FIELD

[0002] The present application relates to the technical field of electronic atomization, and in particular to an atomizer, an atomization core and an electronic atomization device.

BACKGROUND

[0003] At present, an electronic atomization device on the market generally includes a power supply and an atomizer, and the atomizer includes an atomization core, an e-liquid storage chamber and an air channel. The liquid storage chamber stores an e-liquid and supplies the e-liquid to the atomization core. An operation mode of the electronic atomization device is that, an electric control part controls and regulates operation modes and operation power of the atomizer, and the atomizer vaporizes the e-liquid in a liquid state into aerogel.

[0004] In general, only one type of e-liquid is provided in the liquid storage chamber, or the e-liquid itself is a mixture of multiple e-liquids. The e-liquid consists of a mother liquor and taste additives. The mother liquor is a mixture of Propylene Glycol (PG) and Vegetable Glycerin (VG), generates smokes and acts as a solvent for the additives. The additives mainly consist of flavorings and nicotine.

[0005] This atomizer made up of a single liquid storage chamber and a single atomization core has the following deficiencies.

1. Atomization temperatures of ingredients, such as the flavorings and the nicotine in the mother liquor and the additives, differ from each other. There is a gradient of optimum atomization temperatures of at least these ingredients. A single atomization core can only provide single power or an environment at a single operation temperature, which cannot completely satisfy different temperatures of all the above matters. For example, the optimum volatilization temperature of the flavorings is 150 °C . At an over-high temperature, ingredients of the flavorings may be damaged, hence the flavor is lost. The optimum volatilization temperature of the nicotine is 170 °C, and a certain amount of the nicotine may be lost at an over-low temperature. Therefore, a single liquid storage chamber and a single atomization core may cause problems that, if the flavor is emphasized, the nicotine may be lost; if the smoke is sufficient, the taste may be bad; or if the nicotine is emphasized, the flavor may be lost.

2. The content of the nicotine is hard to be quantitatively controlled. Although the content of nicotine in each type of e-liquids is fixed, nicotine intake is hard to be precisely controlled in actual operations, since the nicotine may be lost due to volatilization when pursuing taste of the flavors.

3. It is difficult to some extent to precisely control volatilization of each active constituent in the additives.

[0006] In addition, the e-liquids in the electronic atomization device are divided into three types, namely an e-liquid containing nicotine, an e-liquid containing mint, and a fruit-flavoured e-liquid. Usage scenarios of the three types of e-liquids differ a little from each other. Smokers having a smoking history are all addicted to nicotine, and generally like the e-liquid containing nicotine. The e-liquid containing mint is mainly for refreshing minds and preventing sleepiness, and is very helpful if a user takes a few puffs during working or driving. The fruit-flavoured e-liquid is generally for entertainment, and does not contain nicotine. Time and frequency of using the electronic atomization device vary with e-liquids and users. When using an electronic atomization device with the fruit-flavoured e-liquid, smokers can take a lot of puffs consecutively. However, when using an electronic atomization device with the e-liquid containing mint, smokers only need to take few puffs to solve the problem, and may feel discomfort if taking many puffs consecutively.

[0007] Generally, the atomizer in the current electronic atomization device can only provide one atomization core for operation. If a user has a demand for multiple types of e-liquids, the atomization core or the e-liquid needs to be changed, or even operation conditions needs to be readjusted such as power and air intake. Moreover, the current electronic atomization device can only provide a single operation mode, for instance, a mouth-to-lung mode or a direct-to-lung mode, which cannot satisfy multiple demands of the user

[0065] In the technical solutions in the present application, two liquid storage chambers are formed in an interior of the atomizer housing, and different e-liquids can be respectively stored in different liquid storage chambers.

In this way, atomization processes of the different e-liquids are independent to each other, and the e-liquids can be atomized at corresponding optimum atomization temperatures, thereby effectively improving smoke quality. Furthermore, different smokes generated from the different e-liquids can be used by the user after being mixed, which increases taste diversity of the smoke, provides more using experiences to the user, and improves practicability of the atomizer.

[0066] Further, in the present application, the different liquid storage chambers are in correspondence to different heating elements. Therefore, the user can choose if the different heating elements are operated at different times or at the same time.

When the heating elements are operated at the same time, different smokes are respectively generated in the different atomization chambers, and two smokes are mixed evenly in the air path channel for the user to vape. The user can also control heating power of the heating elements. For example, the user can control different heating elements to be operated at different heating power according to using habits and likes, such that the smoke being generated can satisfy various using demands, which enriches using options of the user. Or, the user can also control the heating power of the different heating elements, such that the different e-liquids can be respectively atomized at their optimum atomization temperatures to produce smokes of proper concentrations. In this way, atomization processes of the e-liquids in the different liquid storage chambers are independent to each other, concentrations of ingredients of the smoke being generated can be ensured, and using experience of the user can be improved.

[0067] Moreover, in the atomizer according to the technical solutions in the present application, two liquid storage chambers isolated from each other and an atomization core mounted at the liquid outlets of the liquid storage chambers are formed in the atomizer housing, such that the e-liquids in the liquid storage chambers can enter the atomization core through the liquid outlets, which enables the e-liquids to be atomized under the action of the atomization core.

The bottom cover is connected to the bottom end of the atomizer housing, and the bottom cover is provided with at least two air inlets in communication with the at least two atomization cores respectively. The air inlet regulating ring is rotatably sleeved at the periphery of the bottom cover, and at least one of the air inlets is opened when the air inlet regulating ring is rotated. In a case that the air inlet regulating ring is rotated such that only one of the air inlets is opened, at least another one of the air inlets is blocked, and air is not able to enter. In this case, one of the atomization cores is not operated, while only the other of the atomization cores is operated, such that only the e-liquid in one of the liquid storage chambers is heated and atomized, and the user can experience the flavor of one of the smokes. In a case that the air inlet regulating ring is further rotated such that at least another one of the air inlets is blocked, and the air inlet being blocked before is communicated and air is able to pass through the air inlet, the other of the atomization cores is not operated, and the one of the atomization cores not being operated before starts to be operated and to heat the e-liquid in the other of the liquid storage chambers, and the user can experience the flavor of the other of the smokes. In a case that the air inlet regulating ring is further rotated such that the air inlets in communication with both of the atomization cores are not blocked and air can pass through, the two atomization cores are operated at the same time, each heats and atomizes the e-liquid in the corresponding liquid storage chamber, and the smokes being generated are mixed together to provide vaping experience for the user. In summary, by rotation of the air inlet regulating ring along a peripheral direction of the atomizer, the air inlets in communication with each atomization core are opened or blocked. In this way, the user is free to choose different favorite flavors, and to choose the smoke with or without nicotine. The user is also free to choose a large amount of smoke, i.e. a direct-to-lung mode, when the air inlets are all opened, or a small amount of smoke, i.e. a mouth-to-lung mode, when a portion of the air inlets is blocked. Therefore, diversity of option and using of the product and the practicality of the product are improved, and various demands of the user are satisfied.

[0074] An atomizer is provided in the present application, to store two different e-liquids, and to heat the different e-liquids at different temperatures by different heating elements, which can satisfy various using habits and likes of different users, diversely satisfy using demands of the user, improve using experience of the user and enrich using options of the user.

[0075] In an atomizer in a first embodiment of the present application, as shown in FIGS. 1 to 5, the atomizer 10 includes an atomizer housing 100, an air path channel 110, liquid storage chambers 120, an atomization core 200 and liquid guiding channels. The atomizer housing 100 is formed with two liquid storage chambers 120 and the air path channel 110 spaced apart from each other. The atomization core 200 is arranged in the air path channel 110, an atomization chamber 201 in communication with the air path channel 110 is provided in the atomization core 200, and at least two atomization chambers 201 are provided in one atomization core 200. The atomization core 200 further includes at least two heating elements 300, and each heating element 300 is correspondingly arranged in one atomization chamber 201. At least one heating element 300 is each arranged in correspondence to one liquid storage chamber 120, and heats an e-liquid, which is delivered to the heating element 300 from the liquid storage chamber 120 arranged in correspondence to the heating element 300, at corresponding power. Each liquid guiding channel is in communication with the heating element 300 and the liquid storage chamber 120. The e-liquid in each liquid storage chamber 120 flows to the corresponding heating element via the liquid guiding channel in communication with the liquid storage chamber 120. The liquid guiding channel is a channel through which the e-liquid in the liquid storage chamber 120 flows to the heating element 300 via a liquid guiding hole 202.

[0076] In the present embodiment, two liquid storage chambers 120 are formed in an interior of the atomizer housing 100, and can store different e-liquids. The e-liquids in the two liquid storage chambers 120 are delivered into different atomization chambers 201 through the liquid guiding holes 202 and the liquid guiding channels to be heated by different heating elements 300 at different power. In this way, atomization processes of the different e-liquids are independent to each other, and the e-liquids can be atomized at corresponding optimum atomization temperatures, thereby effectively improving smoke quality. Furthermore, different smokes generated from the different e-liquids can be used by the user after being mixed, which increases taste diversity of the smoke, provides more using experiences to the user, and improves practicability of the atomizer.

[0077] Further, the user can also control the heating power of the heating elements, such that tastes of produced smokes are diverse, thereby improving using experience of the user.

[0078] Further, in the present embodiment, each heating element 300 is electrically connected in series or electrically connected in parallel. That is, multiple heating elements 300 can be operated at the same time or at different times.

[0079] In some embodiments, different liquid storage chambers 120 store e-liquids of different flavors. The multiple heating elements 300 are electrically connected in parallel to heat the e-liquids in different liquid storage chambers 120 at different times, which enables the user to vape smokes of different flavors. It may be appreciated that, e-liquids of different flavors are added with different kinds of flavorings, and the different kinds of flavorings has different atomization temperatures. Therefore, in the present application, different heating elements 300 heat the e-liquids with different flavors at different power, such that the e-liquids of different flavors are all atomized at their optimum atomization temperatures, which prevents the flavorings from being atomized insufficiently or from being burnt, and further ensures smokes of various flavors to have optimum tastes.

[0080] In the present embodiment, since atomization temperatures of the flavorings and nicotine are different, a mother liquor containing nicotine (i.e. a nicotine e-liquid) and a mother liquor containing the flavorings (i.e. a flavoured e-liquid) are respectively stored in different liquid storage chambers 120. In this way, the two liquid storage chambers 120 can be respectively used for storing the nicotine e-liquid and the flavoured e-liquid. The nicotine e-liquid and the flavoured e-liquid enter different atomization chambers 201 via the liquid guiding holes 202 through different liquid guiding channels, and are heated by different heating elements 300, producing a nicotine-type smoke and a flavoured-type smoke.

[0081] It should be noted that, since an isolating annular plate is arranged between each two adjacent atomization chambers 201, the e-liquids entering into each atomization chamber 201 may not be mixed with each other, and only aerosols (i.e. smokes) after atomization are mixed. In this way, the user operates the atomizer 100, and the atomizer 100 separately regulates operation temperature of each heating element 300, thereby heating and atomizing the different e-liquids.

[0082] In the present embodiment, the different heating elements 300 may be operated independently at the same time. In this case, each heating element 300 can heat the corresponding e-liquid at the same time. For example, in a case that the atomizer 100 is provided with two atomization chambers 201, and each atomization chamber 201 is provided with one heating element 300 therein, when the atomizer 100 is operated, one heating element 300 heats the nicotine e-liquid, and the other heating element 300 heats the flavoured e-liquid at the same time. In this way, the nicotine smokes and the flavoured smokes can be evenly mixed in the air path channel 110 for the user to vape.

[0083] In the present embodiment, the different heating elements 300 may also be operated independently at different times. In this case, each heating element 300 can heat the corresponding e-liquid at a different time period. For example, in a case that the atomizer 10 is provided with two atomization chambers 201, and each atomization chamber 201 is provided with one heating element 300 therein, when the atomizer 10 is operated, one heating element 300 heats the nicotine e-liquid at a first time period, and the other heating element 300 is not operated at the first time period. In this way, only the nicotine smoke is produced, and is vaped into mouth by the user through the air path channel 110. Conversely, the one heating element 300 is not operated at a second time period, and the other heating element 300 heats the flavoured e-liquid at the second time period. In this way, only the flavoured-type smoke is produced, and is vaped into mouth by the user through the air path channel 110.

[0084] Moreover, e-liquids of different types, or e-liquids of the same type but having different concentrations, have different temperatures suitable for heating and atomization. That is to say, the heating elements 300 for heating and atomizing different e-liquids have different optimum heating power. For example, an e-liquid having a high nicotine concentration requires relatively lower heating power for a better atomization effect, while an e-liquid having a low nicotine concentration requires relatively higher heating power for a better atomization effect. Therefore, in the present application, different liquid storage chambers 120 are in correspondence to different heating elements 300. The user may control the different heating elements 300 to be operated at different heating power according to using habits and likes, so as to produce e-liquid smokes of different types or smokes of the same type but having different concentrations that can satisfy various using demands of the user, thereby enriching using options of the user.

[0085] For example, the user may control the heating power of different heating elements 300, such that the nicotine e-liquid and the flavoured e-liquid can be respectively atomized at their optimum atomization temperatures, so as to produce the nicotine-type smoke and the flavoured-type smoke having proper concentrations. In this way, atomization processes of the nicotine e-liquid and the flavoured e-liquid are independent to each other, and nicotine concentration of the nicotine-type smoke and flavoured concentration of the flavoured-type smoke can both be ensured. The user may choose that the atomizer produces only the nicotine-type smoke, or produces only the flavoured-type smoke, or produces both the nicotine-type smoke and the flavoured-type smoke at the same time according to likes, which enriches various using and diverse tastes for the user, thereby improves using experience of the user.

[0086] In the present embodiment, since the nicotine e-liquid can be independently heated, not only an intake at each time is controlled, but also an accumulated intake is alerted for safety. For example, a master control board on a host may monitor items, such as daily an accumulated operation frequency and an operation duration for a single time, of the heating element in correspondence to the nicotine e-liquid, which makes it convenient for the user to control daily intake of nicotine.

[0087] Further, in the present embodiment, as shown in FIG. 5, the atomization core 200 includes a core housing 210. At least two atomization chambers 201 are formed in the core housing 210, and the liquid guiding holes 202 are formed on a housing wall of the core housing 210. Each atomization chamber 201 is provided with a liquid guider 400 therein, the heating element 300 is mounted in the liquid guider 400, and liquid guiders 400 in any two atomization chambers 201 are not in communication with each other. It may be appreciated that, the liquid guiders 400 in different atomization chambers 201 are for absorbing different e-liquids delivered from different liquid storage chambers via the liquid guiding holes 202 through the liquid guiding channels. In the present embodiment, different liquid guiders 400 are not in communication with each other, which prevents different e-liquids from permeating through each other through the liquid guiders 400 and causing crossed flavors, affecting the using experience of the user.

[0088] Further, in the present embodiment, as shown in FIGS. 1 and 2, an injection hole 121 is provided on the atomizer housing 100 in correspondence to each liquid storage chamber 120 for the user to add the e-liquid into the liquid storage chamber 120. In this way, the user can add different e-liquids into different liquid storage chambers 120 according to likes. To ensure taste and quality of the smoke, the heating elements 300 in correspondence to the different liquid storage chambers 120 have heating temperatures at different intervals respectively. The user is supposed to consider matching an optimum temperature of the e-liquid with the heating temperature of the heating element 300, and add different e-liquids into corresponding liquid storage chambers 120. Or, after injecting the e-liquid, the user is supposed to set the power, in correspondence to the optimum atomization temperatures of the different e-liquids, of the heating elements 300 corresponding to different liquid storage chambers 120, so as to ensure all the different e-liquids to be atomized at their optimum atomization temperatures.

[0089] In the present application, multiple atomizer structures and atomization core structures are provided as follows. No matter which atomizer structure and atomization core structure is provided, each liquid storage chamber 120 supplies the e-liquid independently, each atomization chamber 201 of the atomization core 200 can be operated independently, and aerosols after being independently atomized can be mixed together by the air path channel 110, or only one aerogel is produced after atomization for the user to vape.

[0090] As shown in FIGS. 1 and 2, the air path channel 110 includes an air inlet 101, an air outlet 102, a first channel 111 connected to the air inlet 101, and a second channel 112 connected to the air outlet 102, and the air inlet 101 is arranged at a side portion of the atomizer housing 100, the air outlet 102 is arranged at a top portion of the atomizer housing 100, the first channel 111 extends in a horizontal direction, and the second channel 112 extends in a vertical direction. At least two atomization chambers 201 in the atomization core 200 are connected in series, and are arranged adjacent to each other in a front-rear direction in an extension direction of the first channel 111, and are in communication with each other. At least two heating elements 300 are horizontally arranged in the corresponding atomization chambers 201 in one-to-one correspondence. Each liquid storage chamber 120 is correspondingly arranged above at least one atomization chamber 201. In this way, the atomizer has a compact inner structure, which is beneficial to maximally taking use of the inner space of the atomizer housing 100. As shown in FIGS. 3 to 5, in the atomization core 200 in the present embodiment, the core housing 210 includes a housing body 211 and a base 212. An inner cavity of the housing body 211 is formed with two atomization chambers 201, and the two atomization chambers 201 are distributed along an axial direction of the housing body 211. An isolating annular plate 213 is arranged between the two atomization chambers 201 (referring to FIG. 5), such that the two liquid guiders 400 are separated apart to prevent different e-liquids from permeating through each other, while not affecting the smoke flowing between different atomization chambers. An air intake 203 is provided at the base 212, and an air outtake 204 is provided at a top portion of the housing body 211, such that the atomization chambers 201 are communicated with the air path channel 110. Furthermore, a limiting structure 214 is provided at the base 212, which prevents the position of the atomization core 200 from being deflected in the air path channel 110. Each heating element 300 may be a spiral heating wire. Each atomization chamber 201 is provided with a heating wire support 220 thereinside for mounting the heating wire. The liquid guider 400 is mounted inside the heating wire support 220, and is sleeved outside the heating wire. It should be noted that, in the present embodiment, the heating element 300 may also be a heating sheet or a conductive ceramic, which is not specifically limited herein. Moreover, liquid guiding holes 202 in communication with the two atomization chambers 201 respectively are provided at a peripheral wall of the core housing 210. The heating wire support 220 is provided with corresponding liquid passing holes to guide the e-liquids flowing through the liquid guiding channels to flow to the liquid guiders 400 to be absorbed by the liquid guiders 400.

[0091] For electrical connection structures in the atomization core 200, the following arrangements are applied. Two positive electrodes 500 are provided in the core housing 210, and the two positive electrodes 500 are electrically connected to a master control board 21 at a host 20 (referring to FIG. 1). Both ends of the two heating wires are provided with pins, a pin at one end of one of the two heating wires and a pin at one end of the other of the two heating wires are electrically connected to different positive electrodes 500 respectively, and a pin at the other end of one of the two heating wires and a pin at the other end of the other of the two heating wires are electrically connected to the core housing. The core housing may be metallic or made of another conductive material to serve as a negative electrode to be electrically connected to the master control board 21. In this way, the two heating wires can be electrically connected to the master control board 21 in parallel, and the master control board 21 can control the two heating wires to heat at different power.

The two liquid storage chambers 120 are arranged above the atomization core 200, and each liquid storage chamber 120 is correspondingly arranged above at least one atomization chamber 200. Bottom portions of the two liquid storage chambers 120 are each provided with a liquid outlet 122, and the liquid outlets 122 are correspondingly connected to different liquid guiding holes 202, such that the two liquid storage chambers 120 are respectively communicated with the heating elements 300 in the two atomization chambers 201 of the atomization core 200.

[0093] In an atomizer in a second embodiment of the present application, as shown in FIGS. 6 and 7, the air path channel 110 includes an air inlet 101, an air outlet 102, a first channel 111 connected to the air inlet 101, and a second channel 112 connected to the air outlet 102. The air inlet 101 is arranged at a side portion of the atomizer housing 100, the air outlet 102 is arranged at a top portion of the atomizer housing 100, the first channel 111 extends in a horizontal direction, and the second channel 112 extends in a vertical direction. At least two air inlets 101 are provided, at least two first channels 111 are provided, and each first channel 111 is correspondingly communicated with one of the air inlets 101.

During the rotation of the air inlet regulating ring 170, there is also a state where only one of the air inlet holes 161 is opened. In this way, the user can vape smoke produced after the e-liquid in only one of the liquid storage chambers 1120 is heated and atomized, and experience the flavor of only one kind of smoke. Furthermore, in the case that only one of the air inlet holes 161 is opened, the amount of air intake is relatively small, which satisfies a mouth-to-lung demand of the user. The atomizer 10 in the technical solutions of the present application further includes a bottom cover 160 having at least two air inlet holes 161 and an air inlet regulating ring 170 rotatably sleeved at a periphery of the bottom cover 160. During rotation of the air inlet regulating ring 170, the air inlet holes 161 of the bottom cover 160 are in different states (an opened state or a blocked state). During the rotation of the air inlet regulating ring 170, there is a state where all of the air inlet holes 161 are opened. At this time, the two corresponding atomization cores 120 are both in an operated state, such that the user can vape the e-liquids with different flavors mixed together. Furthermore, a large amount of air intake could be achieved when the user is vaping the e-liquids, which satisfies a direct-to-lung demand of the user. During the rotation of the air inlet regulating ring 170, there is also a state where only one of the air inlet holes 161 is opened. In this way, the user can vape smoke produced after the e-liquid in only one of the liquid storage chambers 112 is heated and atomized, and experience the flavor of only one kind of smoke. Furthermore, in the case that only one of the air inlet holes 161 is opened, the amount of air intake is relatively small, which satisfies a mouth-to-lung demand of the user. Certainly, during the rotation of the air inlet regulating ring 170, there is also a case that three or more than three air inlet holes 161 are opened, so as to change the atomization core that external air can be entered and further be mixed with the smoke. The number of the air inlet holes 161 is not specifically limited herein.

[0119] To enable the air inlet regulating ring 170 in the technical solutions in the present application to have both states where at least two air inlet holes 161 are opened or only one of the air inlet holes 161 is opened, in an embodiment, two atomization cores 200 and two air inlet holes 161 are provided as an example for description. Specifically, in the present embodiment, the bottom cover 160 is a cylinder, the two air inlet holes 161 are spaced apart from each other on a side wall of the cylinder along a peripheral direction of the atomizer 10, and an arc angle formed between the two air inlet holes 161 is 180°. Three ventilation holes 171 are provided on the air inlet regulating ring 170, and the three ventilation holes 171 are a first air outlet 171a, a second air outlet 171b and a third air outlet 171c respectively. An arc angle between the first air outlet 171a and the second air outlet 171b is 180°, and an arc angle between the first air outlet 171a and the third air outlet 171c and an arc angle between the second air outlet 171b and the third air outlet 171c are both 90°. In a case that two of the ventilation holes 171 are in one-to-one correspondence to the two air inlet holes 161 in a radial direction of the bottom cover 160, the two air inlet holes 161 are respectively communicated with the two ventilation holes 171, and the state where the two air inlet holes 161 are both opened is achieved, such that the user can vape smoke with two flavors mixed together, and the amount of air intake is relatively large, which can satisfy the direct-to-lung demand of the user. Base on this state, in a case that the air inlet regulating ring 170 is further rotated by 90° in a clockwise direction or a counter-clockwise direction, only one of the air inlet holes 161 is opened, such that the user can vape smoke of only one kind of flavor, and the amount of air intake is decreased, which can satisfy the mouth-to-lung demand of the user.

[0120] In the atomizer 10 according to the technical solutions in the present application, two liquid storage chambers 1120 isolated from each other and an atomization core 200 mounted at the liquid outlets 131 of the liquid storage chambers 1120 are formed in the atomizer housing 100, such that the e-liquids in the liquid storage chambers 1120 can enter the atomization core 200 through the liquid outlets 131, which enables the e-liquids to be atomized by the atomization core 200. At least two liquid storage chambers 1120 isolated from each other and at least two atomization cores 200 are provided, and the at least two atomization cores 200 are respectively mounted at the liquid outlets 131 of the at least two liquid storage chambers 1120. In this way, the user can inject different e-liquids into different liquid storage chambers 1120, which satisfies the demands of the user for vaping smoke of different flavors. The bottom cover 160 is connected to the bottom end of the atomizer housing 100, and the bottom cover 160 is provided with at least two air inlet holes 161 respectively communicated with the at least two atomization cores 200. The air inlet regulating ring 170 is rotatably sleeved at the periphery of the bottom cover 160, and at least one of the air inlet holes 161 is opened when the air inlet regulating ring 170 is rotated. In a case that the air inlet regulating ring 170 is rotated such that only one of the air inlet holes 161 is opened, at least another one of the air inlet holes 161 is blocked, and air is not able to enter. In this case, one of the atomization cores 200 is not operated, while only the other of the atomization cores is operated, such that the e-liquid in only one of the liquid storage chambers 1120 is heated and atomized, and the user can experience the flavor of one kind of smoke. In a case that the air inlet regulating ring 170 is further rotated such that at least another one of the air inlet holes 161 is blocked, and the air inlet hole 161 being blocked before is communicated and air is able to pass through, the other of the atomization cores 200 is not operated, and the one of the atomization cores 200 not being operated before starts to be operated and to heat the e-liquid in the other of the liquid storage chambers 1120, and the user can experience the flavor of the other kind of smoke. In a case that the air inlet regulating ring 170 is further rotated such that the air inlet holes 161 in communication with the two atomization cores 200 are not blocked and air can pass through, the two atomization cores 200 are operated at the same time and each heats and atomizes the e-liquid in the corresponding liquid storage chamber 1120, and smoke being produced is mixed together to provide vaping experience for the user. In summary, by rotation of the air inlet regulating ring 170 along a peripheral direction of the atomizer 10, the air inlets in communication with each atomization core 200 are opened or blocked. In this way, the user is free to choose different favorite flavors for vaping, and to choose the smoke with or without nicotine. The user is also free to choose a large amount of smoke, i.e. a direct-to-lung mode, when the air inlet holes 161 are all opened, or a small amount of smoke, i.e. a mouth-to-lung mode, when a portion of the air inlets is blocked. Therefore, diversity of option and using of the product and the practicality of the product are improved, and various demands of the user are satisfied.

[0121] Specifically, in an embodiment, referring to FIGS. 27 to 32 in conjunction, two atomization cores 200 and two air inlet holes 161 are provided. The two air inlet holes 161 are symmetrically arranged with respect to a central axis of the bottom cover 160 along a radial direction of the bottom cover 160, i.e. an angle between the two air inlet holes 161 is 180°. Three ventilation holes 171 are provided along a peripheral direction of the air inlet regulating ring 170, and the three ventilation holes 171 are a first air outlet 171a, a second air outlet 171b and a third air outlet 171c respectively. An arc angle between the first air outlet 171a and the second air outlet 171b is 180°, and an arc angle between the first air outlet 171a and the third air outlet 171c and an arc angle between the second air outlet 171b and the third air outlet 171c are both 90°. When the bottom cover 160 is rotated, the two air inlet holes 161 are respectively communicated with the first air outlet 171a and the second air outlet 171b, such that the two air inlet holes 161 are each in an opened state; or, one of the air inlet holes 161 is in communication with the third air outlet 171c, and the other of the air inlet holes 161 is blocked.

[0122] The bottom cover 160 has a cylinder shape, and the two air inlet holes 161 may be arranged at a side wall of the cylinder or a bottom wall of the cylinder. The two air inlet holes 161 are symmetrically arranged with respect to the central axis of the bottom cover 160 along the radial direction of the bottom cover 160, such that an angle between the two air inlet holes 161 formed on the bottom cover 160 is 180°. At this time, the atomization cores 200 may be arranged along a left-right direction or a front-rear direction, such that the two atomization cores 200 are in correspondence to the two air inlet holes 161. The air inlet regulating ring 170 has three ventilation holes 171. An arc angle between the first air outlet 171a and the second air outlet 171b of the three ventilation holes 171 is 180°, and an arc angle between the first air outlet 171a and the third air outlet 171c and an arc angle between the second air outlet 171b and the third air outlet 171c are both 90°. In this way, the first air outlet 171a and the second air outlet 171b have a state where the first air outlet 171a and the second air outlet 171b are in correspondence to the two air inlet holes 161 respectively, and a state where only one of the air inlet holes 161 is opened.

[0123] The two air inlet holes 161 are respectively defined as a first air inlet hole 161a and a second air inlet hole 161b. Specifically, referring to FIGS. 22 and 23, in a first state, the two air inlet holes 161 (the first air inlet hole 161a and the second air inlet hole 161b) are respectively communicated with the first air outlet 171a and the second air outlet 171b, such that the two air inlet holes 161 (the first air inlet hole 161a and the second air inlet hole 161b) are both opened, which increases the amount of air intake, and satisfies the direct-to-lung demand of the user.

[0124] Referring to FIGS. 29 and 30 in conjunction, based on the first state, after the air inlet regulating ring 170 is further rotated by 90° in the clockwise direction, the air inlet regulating ring 170 is in a second state. At this time, the third air outlet 171c is correspondingly communicated with the first air inlet hole 161a, the first air outlet 171a or the second air outlet 171b is not in communication with any of the air inlet holes 161, and the second air inlet hole 161b is blocked by a wall surface of the air inlet regulating ring 170, such that air can pass through only one of the air inlet holes 161, which satisfies the mouth-to-lung demand of the user.

[0125] Referring to FIGS. 31 and 32, based on the first state, after the air inlet regulating ring 170 is further rotated by 90° in the counter-clockwise direction, the air inlet regulating ring 170 is in a third state. At this time, the third air outlet 171c is correspondingly communicated with the second air inlet hole 161b, the first air outlet 171a or the second air outlet 171b is not in communication with any air of the inlet holes 161, and the first air inlet hole 161a is blocked by the wall surface of the air inlet regulating ring 170, such that air can pass through only one of the air inlet holes 161, which can also satisfy the mouth-to-lung demand of the user.

[0126] Furthermore, by defining the above three ventilation holes 171 on the air inlet regulating ring 170, the user only needs to rotate the air inlet regulating ring 170 by 180° for realizing the alternate opening and blocking of the two air inlet holes 161, and only needs to rotate the air inlet regulating ring 170 by 90° for realizing the switching between the state where the two air inlet holes 161 are both opened and the state where only one of the air inlet holes 161 is opened, hence the rotation angle is small, which facilitates operation of the user.

[0127] Further, referring to FIGS. 27 and 32 in conjunction, the bottom cover 160 includes a bottom wall 160a and a side wall 160b. The side wall 160b is connected to the bottom wall 160a, and one end of the side wall 160b away from the bottom wall 160a is connected to the atomizer housing 100. The air inlet holes 161 are arranged on the side wall 160b.

[0128] When the air inlet regulating ring 170 is sleeved outside the bottom cover 160, it is basically sleeved outside the side wall 160b of the bottom cover 160. Thus by providing the air inlet holes 161 on the side wall 160b of the bottom cover 160, the air inlet holes 161 can be directly communicated with the ventilation holes 171 on the air inlet regulating ring 170 instead of being communicated with the ventilation holes 171 on the air inlet regulating ring 170 through a relatively long channel, such that the structure of the bottom cover 160 is simplified, and air inlet path is shortened, which facilitates cleaning and clearing of the air inlet channel, and ensures stable air inletting effects.

[0129] Further, referring to the FIGS. 27 to 29 in conjunction, the atomizer housing 100 includes a housing 1100 and connection tubes 130. At least two mounting chambers 1020 isolated from each other are formed in the housing 1100, and each mounting chamber 1020 is mounted with one connection tube 130 thereinside. Liquid storage chambers 1120 are formed between outer walls of the connection tubes 130 and an inner wall of the housing 1100. Each connection tube 130 is provide with a liquid outlet 131, the atomization core 200 is detachably mounted in the connection tube 130, and each connection tube 130 is formed with a first air outlet channel 1010 thereinside.

[0130] The liquid storage chambers 1120 are formed between the outer walls of the connection tubes 130 and the inner wall of the housing 1100, and the connection tubes 130 are provided with the liquid outlets 131, therefore the e-liquids in the liquid storage chambers 11 can flow into the connection tubes 130 via the liquid outlets 131, and the atomization cores 200 arranged in the connection tubes 130 can absorb the e-liquids flowing into the connection tubes 130, and heat the e-liquids to form smoke for the user to vape. Furthermore, the liquid storage chambers 1120 are formed between the outer walls of the connection tubes 130 and the inner wall of the housing 1100, instead of providing an independent liquid storage tank structure, therefore the overall structure of the atomizer 10 is simplified. Moreover, through the connection tubes 130, the atomization cores 200 and the liquid storage chambers 1120 are communicated only by the liquid outlets 131, and other parts thereof are isolated from each other, therefore that the atomization cores 200being directly immersed in the e-liquids and a large amount of liquid leakage are prevented. By arranging the first air outlet channel 1010 in each connection tube 130, smoke, formed after the atomization core 200 heats the e-liquid, can flow out of the first air outlet channel 1010 of the connection tube 130 for the user to vape the smoke.

[0131] Further, as shown in FIG. 23, each atomization core 200 is provided in one first air outlet channel 1010.

[0132] By arranging each atomization core 200 in the first air outlet channel 1010, the smoke, formed after the atomization core 200 heats the e-liquid, can directly flow out of the first air outlet channel 1010 of the connection tube 130, such that the air outlet path is shortened, and that the residual condensate remains on the wall is reduced.

[0133] Further, as shown in FIG. 23, the atomizer 10 further includes a mouthpiece 190, the mouthpiece 190 is in communication with the at least two first air outlet channels 1010, and is arranged at a side of the first air outlet channels 1010 away from the atomization cores 200.

[0134] The mouthpiece 190 is in communication with the at least two first air outlet channels 1010, such that the user can vape smokes formed in the at least two first air outlet channels 1010 via the mouthpiece 190 at the same time, and can further vape smokes of different flavors mixedly, and a sufficient smoke intake is provided to the user who adopts a direct-to-lung mode. Furthermore, by arranging the mouthpiece 190 at the side of the first air outlet channels 1010 away from the atomization cores 200, the user is prevented from vaping the e-liquid in the atomization core 200 without being heated.

[0135] In the embodiments of the present application, the atomizer 10 includes two first air outlet channels 1010, and the mouthpiece 190 is in communication with both the two first air outlet channels 1010. The number of the first air outlet channels 1010 is not specifically limited herein.

[0136] Further, referring to FIGS. 22, 24 and 25 in conjunction, each of the atomization cores 200 further includes a limiting cover 140 and a resilient movable assembly 150. The limiting cover 140 covers a top end of the connection tube 130, and the resilient movable assembly 150 is arranged in the connection tube 130. One end of the resilient movable assembly 150 is resiliently connected to the limiting cover 140, the other end of the resilient movable assembly 150 abuts against the atomization core 200. The resilient movable assembly 150 can slide back and forth in the connection tube 130 so as to open or block the liquid outlet 131.

[0137] By providing the limiting cover 140 and the resilient movable assembly 150 where one end of the resilient movable assembly 150 is connected to the limiting cover 140, the limiting cover 140 performs a good supporting and limiting to the resilient movable assembly 150, which prevents the resilient movable assembly 150 from getting out of the connection tube 130. Moreover, the other end of the resilient movable assembly 150 abuts against the atomization core 200, and can slide back and forth in the connection tube 130. In this way, the resilient movable assembly 150 can drive the atomization core 200 to move when sliding, therefore the atomization core 200 has different states when moving in the connection tube 130.

[0138] Specifically, it may be appreciated that, the atomization core 200 has a liquid inlet. When the atomization core 200 moves in the connection tube 130 along with the resilient movable assembly 150, the liquid inlet can be communicated with the liquid outlet 131 of the connection tube 130. In this way, the e-liquid flowing out of the liquid outlet 131 can flow into the atomization core 200 via the liquid inlet of the atomization core 200. Certainly, when the atomization core 200 continues moving, the liquid inlet is staggered from the liquid outlet 131, such that the resilient movable assembly 150 blocks the liquid outlet 131, thereby preventing the e-liquid in the liquid storage chamber 1120 from flowing into the atomization core 200 when the e-liquid in the liquid storage chamber 1120 is not required to be atomized, and further preventing the e-liquid in the atomization core 200 from being saturated and therefore leaking.

[0139] In an embodiment, the atomizer 10 can be connected to the host into a whole. In a case that the atomizer 10 is not connected with the host into a whole, the atomizer 200 is under the action of the gravity, such that the resilient movable assembly 150 is in a stretched state, and the resilient movable assembly 150 is in a state of blocking the liquid outlet 131. The host may have a cooperation structure abutting against the atomization core 200. After the atomizer 10 is connected to the host into a whole, the atomization core 200 can move upwards and compress the resilient movable assembly 150. At this time, the resilient movable assembly 150 steps aside the liquid outlet 131, such that the liquid inlet of the atomization core 200 is in communication with the liquid outlet 131 of the connection tube 130, whereby the e-liquid in the liquid storage chamber 1120 flows into the atomization core 200 after the atomizer 10 is connected to the host into a whole. When it is required to switch to a non-operation state, only plucking the atomizer 10 off the host is needed, such that deformation of the resilient movable assembly 150 is restored, and the resilient movable assembly 150 abuts the atomization core 200 and moves downwards, which makes the liquid inlet not in communication with the liquid outlet 131 any more, and realizes the resilient movable assembly 150 blocking the liquid outlet 131 and preventing the leakage of the liquid at the liquid outlet 131.

[0140] The resilient movable assembly 150 may only include a spring tube or a resilient sheet, or, apart from that, the resilient movable assembly may further includes a guiding sleeve for mounting the spring tube, and the guiding sleeve may be fixedly connected to the limiting cover or may move along with the spring.

[0141] Specifically, in an embodiment, as shown in FIG. 24, the resilient movable assembly 150 includes a movable valve tube 151 and a spring 152, and the movable valve tube 151 abuts against the atomization core 200. One end of the spring 152 is connected to the movable valve tube 151, and the other end of the spring 152 is connected to the limiting cover 140.

[0142] A side wall of the movable valve tube 151 does not have a hole structure, and can serve as a component for blocking the liquid outlet 131. The movable valve tube 151 is combined with the spring 152, which ensures the resilient movable assembly 150 to have a state of stably blocking the liquid outlet 131 and a state of stepping aside and opening the liquid outlet 131.

[0143] Further, please refer to FIGS. 24 and 25 in conjunction, an inner wall of the connection tube 130 is protrudingly provided with a limiting ring 132, the atomization core 200 is clamped in the limiting ring 132, and is slidable in an axial direction of the limiting ring 132, such that the movable valve tube 151 is able to abut against the limiting ring 132 to block the liquid outlet 131 when moving downwards.

[0144] By providing the limiting ring 132 protruding from the inner wall of the connection tube 130, the limiting ring 132 has a limiting effect on a downward motion of the movable valve tube 151, which prevents the spring 152 from losing resilience due to being stretched by the atomization core 200 for a long time. Moreover, the movable valve tube 151 can block the liquid outlet 131 when abutting against the limiting ring 132, thus leakage of the liquid in the liquid storage chamber 1120 is prevented in a natural state.

[0145] Specifically, referring to FIGS. 23 to 25 in conjunction, each of the atomization cores 200 includes a support sleeve 1210, a liquid guider 1220 and a heating body 123, and the support sleeve 1210 is mounted in the connection tube 130. The support sleeve 1210 is further provided with a liquid inlet 1210a, and the liquid inlet 1210a is in communication with the liquid outlet 131. The liquid guider 1220 is arranged in the support sleeve 1210 and is mounted at the liquid inlet 1210a. The heating body 123 is arranged in the support sleeve 1210, the liquid guider 1220 envelops outside the heating body 123, and the heating body 123 is formed with a first air inlet channel 123a for communicating the air inlet 161 with the first air outlet channel 1010.

[0146] By providing the support sleeve 1210 and the support sleeve 1210 having the liquid inlet 1210a, the e-liquid can only flow into an interior of the atomization core 200 via the liquid inlet 1210a. By arranging the liquid guider 1220 in the support sleeve 1210 and mounting the liquid guider 1220 at the liquid inlet 1210a, the liquid guider 1220 can absorb the e-liquid via the liquid inlet 1210a, and the e-liquid is further heated and atomized by the heating body 123 enveloped by the liquid guider 1220 to produce smoke for the user to vape. Moreover, the first air inlet channel 123a (FIG. 20) is formed in the heating body 123, and the first air inlet channel 123a is in communication with the air inlet hole 161 and the first air outlet channel 1010. In this way, on one hand, smoke formed by heating the e-liquid by the heating body 123 can be mixed with air entering via the air inlet hole 161; on the other hand, the mixed smoke can flow out through the first air outlet channel 1010 to provide a good vaping taste for the user.

[0147] Further, referring to FIG. 23 to 25, each atomization core 200 further includes a conductive electrode 124, and the conductive electrode 124 is mounted at a bottom end of the support sleeve 1210 and is electrically connected to the heating body 123.

[0148] The conductive electrode 124 may be electrically connected to a power supply, and the power supply provides a current to the conductive electrode 124. Further, the conductive electrode 124 is electrically connected to the heating body 123, such that the conductive electrode 124 provides the current to the heating body 123, so that the heating body 124 stably heats the e-liquid. By providing the conductive electrode 124 at the bottom end of the support sleeve 1210, electrical connection between the heating body 123 and the power supply via the conductive electrode 124 is facilitated.

[0149] Further, as shown in FIG. 23, a second air inlet channel 124a is formed in the conductive electrode 124, and two ends of the second air inlet channel 124a are in communication with the first air inlet channel 123a and the air inlet hole 161 respectively.

[0150] By such arrangements, the conductive electrode 124 also performs a good bridging effect on the communication between the first air inlet channel 123a and the air inlet hole 161. Furthermore, by providing the second air inlet channel 124a at the conductive electrode 124, material cost of the conductive electrode 124 becomes lower.

[0151] Further, referring to FIGS. 23 to 27, each of the air inlet holes 161 is correspondingly communicated with the second air inlet channel 124a of one conductive electrode 124.

[0152] Each of the air inlet holes 161 is in correspondence to the second air inlet channel 124a of one conductive electrode 124, such that each of the air inlet holes 161 can be communicated with one first air inlet channel 123a via one second air inlet channel 124a, and two different second air inlet channels 124a are independent to each other and may not affect each other. In this way, in a case that air enters both of the two second air inlet channels 124a, the direct-to-lung demand of the user is satisfied. In a case that the air enters only one of the two second air inlet channels 124a, the other one of the second air inlet channels 124a may not be affected and can keep in a state where no air enters, and the mouth-to-lung demand of the user is satisfied.

[0153] Further, as shown in FIG. 25, the liquid guider 1220 includes a main body portion 1221 and a protrusion ring 1222. The main body portion 1221 is mounted at the liquid inlet 1210a, and is sleeved outside the heating body 123. The protrusion ring 1222 is protrudingly arranged at a bottom end of the main body portion 1221, and abuts against the bottom end of the support sleeve 1210.

[0154] The main body portion 1221 of the liquid guider 1220 is mounted at the liquid inlet 1210a and is sleeved outside the heating body 123. In this way, the e-liquid flowing in from the liquid inlet 1210a is firstly absorbed by the main body portion 1221, and the heating body 123 firstly heats the e-liquid absorbed by the main body portion 1221 to form smoke for the user to vape. Moreover, the bottom end of the main body portion 1221 is protrudingly provided with the protrusion ring 1222, and the protrusion ring 1222 abuts against the bottom end of the support sleeve 1210, such that the protrusion ring 1222 can absorb the condensate, which prevents the condensate at the main body portion 1221 from directly dripping to the bottom end of the support sleeve 1210 and flowing out of the bottom end of the support sleeve 1210.

[0155] Further, referring to FIGS. 24 and 25 in conjunction, a top end of the second air inlet channel 124a extends into a space enclosed by the protrusion ring 1222, and is provided close to the bottom end of the first air inlet channel 123a.

[0156] The top end of the second air inlet channel 124a extends into a space formed being enclosed by the protrusion ring 1222, such that the second air inlet channel 124a is closer to the bottom end of the first air inlet channel 123a, such that the top end of the second air inlet channel 124a is higher than a bottom wall of the support sleeve 1210. Thus, after the e-liquid dripping from the liquid guider 1220 drips on the bottom wall of the second air inlet channel 1210, the e-liquid can hardly leak to an exterior of the atomizer 10, thereby achieving a good effect of preventing leakage of the e-liquid.

[0157] Further, an electronic atomization device is also provided in the present application.

[0158] In another embodiment of the present application, referring to FIGS. 33 to 38, and FIGS. 40 to 43, the electronic atomization device includes an atomizer 10 and a power supply host. The atomizer 10 includes an atomizer housing 100, an atomization core 200 and a bottom cover 112c. At least two liquid storage chambers 111a isolated from each other are formed in the atomizer housing 100, and a chamber wall of each of the liquid storage chambers 111a is provided with a liquid outlet 111b. The atomization core 200 includes at least two atomization portions 121a (as shown in FIG. 34) isolated from each other, and the at least two atomization portions 121a isolated from each other are respectively arranged at different liquid outlets 111b (FIG. 34). The bottom cover 112c is connected to a bottom end of the atomizer housing 100, the atomization core 200 is covered by the bottom cover 112c, a bottom wall of the bottom cover 112c is provided with at least two air inlets 112b, and an opening of each air inlet 112b faces a different atomization portion 121a. The power supply host includes a host housing 2100. The bottom cover 112c is rotatably mounted on the host housing 2100, and in a case that the bottom cover 112c is rotated with respect to the host housing 2100, at least one of the air inlets 112b is in an opened state.

[0159] The at least two liquid storage chambers 111a isolated from each other are formed in the atomizer housing 100, the chamber wall of each liquid storage chamber 111a is provided with the liquid outlet 111b, and the at least two atomization portions 121a of the atomization core 200 isolated from each other are mounted at the liquid outlets 111b of different liquid storage chambers 112a respectively. In this way, e-liquids of different flavors can be stored in different liquid storage chambers 111a, such that the user can selectively vape the e-liquid of a favorite flavor, and make the atomization portion 121a corresponding to this e-liquid be in an operation state, thereby satisfying vaping demands of the user for different flavors. The atomizer 10 in the technical solutions in the present application further includes a bottom cover 112c being provided with at least two air inlets 112b and a host housing 2100 which can be rotated with respect to the bottom cover 112c. In a case that the bottom cover 112c is rotated with respect to the host housing 2100, the air inlets 112b on the bottom cover 112c are in different states (an opened state or a blocked state) with respect to the host housing 2100, and at least one of the air inlets 112b is in the opened state, such that the user can vape smoke having at least one flavor.

[0160] Specifically, during rotation of the bottom cover 112c with respect to the host housing 2100, there is a state where one of the air inlets 112b is opened. At this time, the atomization core 200 in correspondence to the one of the air inlets 112b being opened is in the operation state, such that the user can vape a flavor of smoke produced from one e-liquid after being heated and atomized. Furthermore, the atomizer has a relatively small amount of air intake when the user is vaping the smoke produced from the e-liquid after being heated and atomized, thereby satisfying the mouth-to-lung demand of the user who likes a small amount of smoke. Conversely, in a case that the bottom cover 112c is further rotated with respect to the host housing 2100, the one of the air inlets 112b being opened before is blocked, and the at least one of the air inlets 112b being blocked before is opened to be in communication with other atomization cores 200. Since the other atomization cores 200 are in communication with other liquid storage chambers 111a, the user can heat and atomize the e-liquids in other liquid storage chambers 111a by rotating the bottom cover 112c with respect to the host housing 2100, thus can experience different flavors of smokes. Moreover, during rotation of the bottom cover 112c with respect to the host housing 2100, there is another state where all of the air inlets 112b are opened. The e-liquids of different flavors in the multiple liquid storage chambers 111a are atomized and mixed together for the user to vape, which provides a mixed-type taste, which cannot be experienced if the user vapes smoke of a single flavor, to the user. Furthermore, after all of the air inlets 112b are opened, the amount of air intake of the atomizer 10 is maximized, which can satisfy the direct-to-lung demand of the user who likes a large amount of smoke.

[0161] To enable the bottom cover 112c and the host housing 2100 in the technical solutions in the present application to have both states including at least two air inlet holes 161 are opened and only one of the air inlets holes 161 is opened during rotation with respect to each other, specifically, in another embodiment, two atomization portions 121a and two air inlet holes 112b are provided as an example for description. The bottom cover 112c is a cylinder, the two air inlet holes 112b are arranged on a bottom wall of the cylinder, and an arc angle formed between the two air inlet holes 112b is 180° with respect to a center of the bottom wall of the bottom cover 112c being taken as a central axis. Three ventilation channels are provided on the host housing 2100, two sides of each of the ventilation channels are in communication with an exterior and one of the air inlets 112b respectively, and three air outlets 2120 of the three ventilation channels are a first air outlet 2120a, a second air outlet 2120b and a third air outlet 2120c respectively. An arc angle between the first air outlet 2120a and the second air outlet 2120b is 180°, and an arc angle between the first air outlet 2120a and the third air outlet 2120c and an arc angle between the second air outlet 2120b and the third air outlet 2120c are both 90°. In a case that the bottom cover 112c is rotated with respect to the host housing 2100, at least one of the air inlets 112b of the bottom cover 112c is in communication with at least one of the air outlets 2120, and at least another one of the air outlets 2120 is in the blocked state. In use, in a case that the bottom cover 112c is rotated with respect to the host housing 2100 by a certain angle, the first air outlet 2120a and the second air outlet 2120b on the host housing 2100 are in communication with the two air inlets 112b (a first air inlet 1121b and a second air inlet 1122b as shown in FIG. 41) respectively. At this time, the two atomization portions 121a are in communication with the exterior through the ventilation channels on the host housing 2100. Hence, when the two atomization portions 121a are both in the operation state, the two atomization portions 121a each can heat the e-liquid in the corresponding atomizer housing 100, and produce smoke of a different flavor. The two kinds of smoke of different flavors are mixed with air flowing in from the exterior, and then are vaped by the user, such that the user can experience smoke of a mixed flavor. Since the two air inlets 112b are both in the opened state, the amount of air intake is relatively large, which can satisfy the direct-to-lung demand of the user who likes a large amount of smoke. Based on this state, referring to FIG. 40, in a case that the bottom cover 112c is further rotated by 90° in a clockwise direction with respect to the host housing 2100, only the third air outlet 2120c is in communication with one of the air inlets 112b (i.e. the first air inlet 1121b in FIG. 41), and the second air outlet 2120b and the first air outlet 2120a are both in the blocked state, and the other one of the air inlets 112b (i.e. the second air inlet 1122b in FIG. 41) is also in the blocked state. In this state, since only one of the atomization cores 200 in communication with the first air inlet 1121b is in communication with the exterior, the user can only vape a flavor of smoke produced by a single e-liquid. Conversely, firstly going back to the state shown in FIG. 38, the first air outlet 2120a and the second air outlet 2120b on the host housing 2100 are in communication with the two air inlets 112b respectively. Then with continued reference to FIG. 39, in a case that the bottom cover 112c is further rotated by 90° in a counter-clockwise direction with respect to the host housing 2100, only the third air outlet 2120c is in communication with the other one of the air inlets 112b (i.e. the second air inlet 1122b in FIG. 41), and the first air outlet 2120a and the second air outlet 2120b are both in the blocked state, and the one of the air inlets 112b (i.e. the first air inlet 1121b in FIG. 41) is also in the blocked state. In this state, since only the other one of the atomization cores 200 in communication with the second air inlet 1122b is in communication with the exterior, the user also can only vape a flavor of smoke produced by a single e-liquid. Furthermore, the amount of air intake is relatively small at this time, which can satisfy the mouth-to-lung demand of the user who likes a small amount of smoke.

[0162] In the technical solutions in the present application, at least two liquid storage chambers 111a isolated from each other are formed in the atomizer housing 100 of the atomizer 10, and different e-liquids can be respectively stored in different liquid storage chambers 111a, thereby providing different flavors for the user. By arranging the at least two atomization portions 121a of the atomization core 200 isolated from each other at the liquid outlets 111b of different liquid storage chambers 111a respectively, each of the atomization portions 121a is in correspondence to one of the liquid storage chambers 111a, and the e-liquid in the liquid storage chamber 111a can flow to the corresponding atomization portion 121a via the liquid outlet 111b for the atomization portion 121a to heat and atomize the e-liquid. In a case that the user choose the e-liquid of one of the flavors, the user only needs to operate the atomization portion 121a in correspondence to the e-liquid of this flavor, such that the user can vape smoke of the demanded flavor. In a case that the user choose the e-liquids of at least two flavors, the user only needs to operate different atomization portions 121a in correspondence to the e-liquids of the at least two flavors respectively, such that the user can vape smoke of the at least two flavors. The at least two air inlets 112b facing different atomization portions 121a respectively are provided on the bottom wall of the bottom cover 112c, and the bottom cover 112c is rotatably mounted on the host housing 2100 of the power supply host. In this way, when the bottom cover 112c is rotated with respect to the host housing 2100, at least one of the air inlets 112b is opened. In a case that the bottom cover 112c is rotated with respect to the host housing 2100 such that only one of the air inlets 112b is opened, at least another one of the air inlets 112b is blocked, and air is not able to enter. In this case, one of the atomization cores 200 is not operated, while only the other of the atomization cores 200 is operated, such that only the e-liquid in one of the liquid storage chambers 111a is heated and atomized, and the user can experience the flavor of one kind of smoke. In a case that the bottom cover 112c is further rotated with respect to the host housing 2100 such that at least another one of the air inlets 112b is blocked, and the air inlet 112b being blocked before is communicated and air is able to pass through, the other of the atomization cores 200 is not operated, and the one of the atomization cores 200 not being operated before starts to be operated and to heat the e-liquid in the other of the liquid storage chambers 111a, and the user can experience the flavor of the other kind of smoke. In a case that the bottom cover 112c is further rotated with respect to the host housing 2100 such that the air inlets 112b in communication with both of the atomization cores 200 both are not blocked and air can pass through, the two atomization cores 200 are operated at the same time, each heats and atomizes the e-liquid in the corresponding liquid storage chamber 111a, and the smokes being produced are mixed together to provide vaping experience of mutually mixed smoke of multiple e-liquids for the user. In summary, by rotation of the bottom cover 112c with respect to the host housing 2100, the air inlets 112b in communication with each atomization core 200 are opened or blocked. In this way, the user is free to choose different favorite flavors, and to choose the smoke with or without nicotine. The user is also free to choose a large amount of smoke, i.e. a direct-to-lung mode, when the air inlets 112b are all opened, or a small amount of smoke, i.e. a mouth-to-lung mode, when a portion of the air inlets 112b is blocked. Therefore, diversity of option and using of the product and the practicality of the product are improved, and various demands of the user can be satisfied.

[0163] Further, referring to FIGS. 35 to 38, and FIGS. 41 to 43, two air inlets 112b are provided, and the host housing 2100 is provided with three second air inlet channels 211a. Each of the three second air inlet channels 211a is provided with an air outlet 2120, and the three air outlets 2120 are all provided on an ventilation regulating end portion 2010(FIGS. 36 and 43) of the host housing 2100. The ventilation regulating end portion 2010 is an end portion of the host housing 2100 close to the bottom cover 112c, and the three air outlets 2120 are a first air outlet 2120a, a second air outlet 2120b and a third air outlet 2120c respectively. An arc angle between the first air outlet 2120a and the second air outlet 2120b is 180°, and an arc angle between the first air outlet 2120a and the third air outlet 2120c and an arc angle between the second air outlet 2120b and the third air outlet 2120c are both 90°. In a case that the bottom cover 112c is rotated with respect to the host housing 2100, at least one of the air inlets 112b of the bottom cover 112c is in communication with at least one of the air outlets 2120, and at least another one of the air outlets 2120 is in the blocked state.

[0164] Specifically, an arc angle formed between the two air inlets 112b with respect to a center of the bottom wall of the bottom cover 112c being taken as a central axis may be 90° or 180° or another degree, as long as at least one air outlet 2120 of the three air outlets 2120 of the three air inlet channels 211 on the host housing 2100 can be communicated with at least one of the air inlets 112b as well as at least another one of the air outlets 2120 is in the blocked state.

[0165] In some embodiments, as shown in FIG. 41, two air inlets 112b are provided on the bottom cover 112c, and are a first air inlet 1121b and a second air inlet 1122b respectively. In the embodiment illustrated by FIG. 41, an arc angle formed between the first air inlet 1121b and the second air inlet 1122b with respect to the center of the bottom wall of the bottom cover 112c being taken as the central axis is 180°. In a case that the bottom cover 112c is rotated with respect to the host housing 2100 by a certain angle, the first air outlet 2120a on the host housing 2100 is in communication with the first air inlet 1121b, and the second air outlet 2120b is in communication with the second air inlet 1122b. In this state, the two atomization cores are both in communication with the exterior through the multiple second air inlet channels 211a on a side wall of the host housing 2100. Hence, in the case that the two atomization cores 200 are both in the operation state, the two atomization cores 200 each can heat the e-liquid in the corresponding atomizer housing 100, and produce smoke of a different flavor at the same time. The two kinds of smoke of different flavors are mixed with air flowing in from the exterior, and then flow out of a second air outlet channel 111c (FIG. 39), such that the user can experience smoke of a mixed flavor. Based on this state, with continued reference to FIG. 43, in a case that the bottom cover 112c is further rotated by 90° in a clockwise direction with respect to the host housing 2100, only the third air outlet 2120c is in communication with the first air inlet 1121b, and the first air outlet 2120a and the second air outlet 2120b are both in the blocked state, and the second air inlet 1122b is also in the blocked state. In this state, since only one of the atomization cores 200 is in communication with the third air outlet 2120c, the air inlet 1121b and the second air inlet channel 211a provided on the side wall of the host housing 2100, and is in communication with the exterior. Hence, in the case that only one of the atomization cores 200 is operated, the e-liquid in the atomizer housing 100 in communication with the one of the atomization cores 200 is atomized, then being mixed with the external air, and flows out of the second air outlet channel 111c, such that the user can vape a flavor of smoke produced by a single e-liquid. Conversely, firstly going back to the state shown in FIG. 41, the first air outlet 2120a and the second air outlet 2120b on the host housing 2100 are in communication with the two air inlets 1121b and 1122b respectively. Then with continued reference to FIG. 42, in a case that the bottom cover 112c is further rotated by 90° in a counter-clockwise direction with respect to the host housing 2100, only the third air outlet 2120c is in communication with the second air inlet 1122b, and the first air outlet 2120a and the second air outlet 2120b are both in the blocked state, and the first air inlet 1121b is also in the blocked state. In this state, differing from the state shown in FIG. 43, the other one of the atomization cores 200 is in communication with the third air outlet 2120c, the second air inlet 1122b and the second air inlet channel 211a provided on the side wall of the host housing 2100, and is in communication with the exterior. Hence, in the case that only the other one of the atomization cores 200 is operated, the e-liquid in the atomizer housing 100 in communication with the other one of the atomization cores 200 is atomized, then mixed with the external air, and flows out of the second air outlet channel 111c, such that the user can vape another smoke of a single flavor produced by another e-liquid.

[0166] In other words, the two air inlets 112b are respectively defined as a first air inlet 1121b and a second air inlet 1122b. Referring to FIG. 41 in specific, in a case that the bottom cover 112c is rotated with respect to the host housing 2100 and is in the first state, the first air inlet 1121b and the second air inlet 1122b of the two air inlets 112b are in communication with the first air outlet 2120a and the second air outlet 2120b respectively, such that the two air inlets 112b are both in the opened state. In the state where the first air outlet 2120a and the second air outlet 2120b are in correspondence to the two air inlets 112b respectively, the two air inlets 112b are both opened, thereby increasing the amount of air intake, and satisfying the direct-to-lung demand of the user.

[0167] Referring to FIG. 42 in specific, based on the first state, the bottom cover 112c is further rotated by 90° in the counter-clockwise direction, and this state of the bottom cover 112c with respect to the host housing 2100 is a second state. At this time, the second air inlet 1122b is in communication with the third air outlet 2120c, and the first air inlet 1121b is blocked by the ventilation regulating end portion 2010 such that one of the air inlets 112b is in the opened state. In this way, one of the atomization portions 121a in correspondence to the second air inlet 1122b is in an opened state, and the other one of the atomization portions 121a in correspondence to the first air inlet 1121b is in a blocked state, such that the amount of air intake is relatively small to satisfy the mouth-to-lung demand of the user.

[0168] Referring to FIG. 43 in specific, based on the first state, the bottom cover 112c is further rotated by 90° in the clockwise direction, and this state of the bottom cover 112c with respect to the host housing 2100 is a third state. At this time, the first air inlet 1121b is in communication with the third air outlet 2120c, and the second air inlet 1122b is blocked by the ventilation regulating end portion 2010 such that the other one of the air inlets 112b is in the opened state. In this way, the other one of the atomization portions 121a in correspondence to the first air inlet 1121b is in the opened state, and the one of the atomization portions 121a in correspondence to the second air inlet 1122b is in the blocked state, such that the amount of air intake is also relatively small to satisfy the mouth-to-lung demand of the user.

[0169] Moreover, by providing the above three air outlets 2120 on the host housing 2100, the user only needs to rotate by 180° for alternately opening or blocking the two air inlets 112b, and only needs to rotate by 90° for switching between the state where the two air inlets 112b are both opened and the state where only one of the air inlets 112b is opened, hence the rotation angle is small, which facilitates operation of the user.

[0170] Specifically, taking the embodiment in FIGS. 41 to 43 as an example, and assuming an initial state of the bottom cover 112c with respect to the host housing 2100 is the second state as shown in FIG. 42, the second air inlet 1122b on the bottom cover 112c is in communication with the third air outlet 2120c on the host housing 2100, the second air inlet 1122b is in the opened state, and the first air inlet 1121b is in the blocked state. At this time, a first liquid storage chamber in communication with the second air inlet 1122b stores a first e-liquid. When a first atomization core in communication with the first liquid storage chamber is operated, the user can vape smoke produced after the first e-liquid is heated and atomized. Then, in a case that the bottom cover 112c is rotated by 90° in the counter-clockwise direction with respect to the host housing 2100, the second air inlet 1122b on the bottom cover 112c is in communication with the first air outlet 2120a on the host housing 2100, and the first air inlet 1121b on the bottom cover 112c is in communication with the second air outlet 2120b on the host housing 2100. At this time, the first liquid storage chamber in communication with the first air inlet 1121b on the bottom cover 112c stores the first e-liquid, and a second liquid storage chamber in communication with the second air inlet 1122b on the bottom cover 112c stores a second e-liquid. Thus, the first atomization core in communication with the first liquid storage chamber and a second atomization core in communication with the second liquid storage chamber are operated at the same time, and heat and atomize the e-liquids in the two liquid storage chambers respectively, and smokes being produced are mixed and then vaped into mouth by the user. Then, in a case that the bottom cover 112c is further rotated by 90° in the counter-clockwise direction with respect to the host housing 2100, the second air inlet 1122b on the bottom cover 112c is blocked by the ventilation regulating end portion 2010 of the host housing 2100, and the first air inlet 1121b on the bottom cover 112c is rotated to be in communication with the third air outlet 2120c. At this time, the second air inlet 1122b is in the blocked state, and the first air inlet 1121b is in the opened state. In this way, the second atomization core in communication with the second air inlet 1122b is operated, and heats and atomizes the e-liquid in the second liquid storage chamber in communication with the second atomization core, and smoke being produced is vaped into mouth by the user. It can be known from above that, the user only needs to rotate 180° for alternately opening and blocking the two air inlets 112b, and only needs to rotate 90° for switching between the state where the two air inlets 112b are both opened and the state where only one of the air inlets 112b is opened.

[0171] Further, referring to FIG. 37 to 40 in conjunction, the bottom cover 112c and the atomization core 200 together enclose to form a first air inlet channel 112a, and the first air inlet channel 112a is in communication with the air inlets 112b. The liquid storage chambers 111a has a bottom wall, the bottom wall of the liquid storage chambers 111a is provided with at least two communication ports 111d, and the at least two communication ports 111d are all in communication with the first air inlet channel 112a. The atomization cores 200 further includes an isolating portion 122b, and the at least two atomization portions 121a are respectively arranged at two opposite sides of the isolating portion 122b.

[0172] The first air inlet channel 112a is formed being enclosed by the bottom cover 112c and the atomization core 200 instead of being separately provided in the bottom cover 112c, which simplifies the structure of the bottom cover 112c, and reduces cost of the bottom cover 112c. Moreover, it may be appreciated that, to facilitate vaping smokes by the user, a second air outlet channel 111c is provided in the electronic atomization device for the smoke to flow out. In the present embodiment, by providing the at least two communication ports 111d both in communication with the first air inlet channel 112a on the bottom wall of the liquid storage chambers 111a, air entered into the first air inlet channel 112a can further flow into the second air outlet channel 111c via the communication ports 111d.

[0173] By providing the isolating portion 122b on the atomization cores 200, and the at least two atomization portions 121a being respectively arranged at the two opposite sides of the isolating portion 122b, the e-liquids in the at least two atomization portions 121a may not be mixed with each other, such that when the user adopts the mouth-to-lung mode, a flavor of smoke vaped from one of the atomization portions 121a is ensured to be purer, and a risk that flavors are crossed with each other is further prevented.

[0174] Further, referring to FIGS. 35 and 36 in conjunction, each second air inlet channel 211a includes a first air inlet sub-channel 2111 and a second air inlet sub-channel 2112, and the first air inlet sub-channel 2111 extends in a direction toward the bottom cover 112c and has an air outlet 2120. The second air inlet sub-channel 2112 is in communication with the first air inlet sub-channel 2111 and is arranged to have an angle with respect to the first air inlet sub-channel 2111, and the second air inlet sub-channel 2112 is in communication with an exterior.

[0175] The first air inlet sub-channel 2111 of the second air inlet channel 211a extends in the direction toward the bottom wall of the bottom cover 112c and has an air outlet, which ensures that the first air inlet channel 112a can be in communication with the second air inlet channel 211a. The second air inlet sub-channel 2112 is in communication with the first air inlet sub-channel 2111 and is arranged to have an angle with respect to the first air inlet sub-channel 2111, hence, an end of the second air inlet sub-channel 2112 away from the first air inlet sub-channel 2111 extends in a direction toward the side wall of the host housing 2100, such that an air inlet opening of the second air inlet sub-channel 2112 is provided on the side wall of the host housing 2100, which makes it easy for the user to observe the state of the second air inlet channel 211a, and facilitates releasing of a space of a bottom portion of the host housing 2100, such that more other components can be arranged at the space of the bottom portion of the host housing 2100 to increase space utilization.

[0176] Specifically, an extension direction of the first air inlet sub-channel 2111 may be arranged perpendicular to the bottom wall of the bottom cover 112c, or may have an acute or obtuse angle with respect to the bottom wall of the bottom cover 112c. An extension direction of the second air inlet sub-channel 2112 may be arranged perpendicular to the extension direction of the first air inlet sub-channel 2111, or may have an acute or obtuse angle with respect to the extension direction of the first air inlet sub-channel 2111. Certainly, in a case that the space utilization is not taken into consideration, the extension direction of the second air inlet sub-channel 2112 may be the same as the extension direction of the first air inlet sub-channel 2111.

[0177] Further, referring to FIGS. 34, 35, 36 and 40 in conjunction, each atomization portion 121a includes a liquid guider 121a and a heating body 121b. The liquid guider 121a is mounted at the liquid outlet 11 1b, and the heating body 121b is arranged at a side of the liquid guider 121a away from the liquid storage chamber 111a.

[0178] By providing the liquid guider 121a and mounting the liquid guider 121 at the liquid outlet 111b, the e-liquid flowing out of the liquid outlet 111b can be absorbed by the liquid guider 121a. By arranging the heating body 121b at the side of the liquid guider 121a away from the liquid storage chamber 111a, the heating body 121b is heated in the operation state, and further heats the e-liquid in the liquid guider 121a, making the e-liquid form smoke for the user to vape. Specifically, the heating body 121b is adhered to the liquid guider 121a, or the heating body 121b is hidden or embedded into the liquid guider 121a, which is not specifically limited herein.

[0179] In an embodiment, the liquid guider 121a is a porous ceramic substrate.

[0180] By applying the porous ceramic substrate to the liquid guider 121a, on one hand, the porous structure of the porous ceramic substrate can adsorb the e-liquid; on the other hand, the liquid guider 121a has a stiffness to a certain degree, therefore is not apt to deform, which facilitates mounting and fixation. Certainly, in other embodiments, the liquid guider 121a may be made of another material which is apt to adsorb the e-liquid. For example, the liquid guider 121a may be a liquid guiding cotton.

[0181] To prevent the e-liquids in the two atomization portions 121a from being crossed with each other due to adsorption of the e-liquids by the isolating portion 122b, the isolating portion 122b is made of a non-porous ceramic material. By such arrangements, the isolating portion 122b can isolate the at least two atomization portions 121a from each other, such that each of the atomization portions 121a can absorb only the e-liquid in the liquid storage chamber 111a in correspondence thereto, and may not absorb the e-liquid in another liquid storage chamber 111a, which ensures that the taste of the e-liquid in each of the atomization portions 121a is pure, and prevents a situation that flavors are crossed with each other. Specifically, the isolating portion 122b may be made of a metallic material or a ceramic material without the porous structure.

[0182] Further, referring to FIGS. 35 and 36, a partition portion is provided in the atomizer housing 100, the partition portion divides the atomizer housing 100 into the two liquid storage chambers 111a isolated from each other, and a second air outlet channel 111c is formed in the partition portion.

[0183] By providing the partition portion in the atomizer housing 100, the partition portion can divide the atomizer housing into the two liquid storage chambers 111a isolated from each other, to prevent a situation that the e-liquids in different liquid storage chambers 111a are mixed with each other, which affects a taste for the user. Moreover, by forming the second air outlet channel 111c in the partition portion instead of separately arranging the second air outlet channel 111c, on one hand, a space in the atomizer housing 100 is fully utilized; on the other hand, different atomization portions 121a are in correspondence to the same second air outlet channel 111c, thereby reducing the number of the second air outlet channel 111c and reducing the space occupation of the electronic atomization device.

[0184] Further, referring to FIGS. 35 to 40, the power supply host further includes a battery assembly 2200, and the atomizer 10 is electrically connected to the battery assembly 2200.

[0185] The battery assembly 2200 is provided, and the atomizer 10 is electrically connected to the battery assembly 200. In this way, the battery assembly can supply power to the atomizer 10 to ensure normal operation of the atomizer 10. Specifically, the battery assembly 2200 is arranged in the host housing 2100 to perform a good protection effect on the battery assembly 2200, and extend a service life of the battery assembly 2200. To prevent the battery assembly 2200 from affecting air inletting smoothness of the second air inlet channel 211a, the second air inlet channel 211a may be arranged at an end of the host housing 2100 close to the bottom cover 112c, i.e. the second air inlet channel 211a is arranged on the ventilation regulating end portion 2010 described hereinabove. The battery assembly 2200 is arranged at the other end of the host housing 2100 away from the bottom cover.

[0186] The above is only the preferred embodiments of the present application, and is not therefore limiting the scope of the patent of the present application. Equivalent structure changes made in the application specification and drawings, or directly or indirectly applied in other related technical fields, are intended to be included within the patent protection scope of the present application.
