Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The present application claims priority to Chinese Patent Application No. 202111557651.7, entitled "ATOMIZATION DEVICE FOR ELECTRONIC CIGARETTE, AND ELECTRONIC CIGARETTE" filed on December 19, 2021, which is incorporated herein by reference in its entirety.

FIELD

[0002] The present disclosure relates to the technical field of electronic cigarettes, and more specifically, to an atomization device for an electronic cigarette and an electronic cigarette.

BACKGROUND

[0003] In recent years, electronic cigarettes have been favored by consumers because of features such as ease of usage and low harm to health. In order to meet the needs of portability and ease of usage, electronic cigarettes have a design trend of a miniaturized volume and a lightweight structure. However, it is very difficult to make existing electronic cigarettes thinner because there are many components inside the electronic cigarettes. If the internal space of an electronic cigarette is designed to be excessively small to meet the demand for miniaturization, internal components of the electronic cigarette are excessively compact, resulting in greater inhaling resistance and poor user experience. Besides, because existing electronic cigarettes are relatively thick, users have poor experience when gripping and carrying electronic cigarettes, and are prone to feel discomfort when holding air outlets of electronic cigarettes.

[0004] Therefore, it is necessary to improve internal structures of electronic cigarettes and optimize electronic cigarette products.

[0064] In other words, the atomization device for an electronic cigarette provided by the embodiments of the present disclosure includes the shell 1, the separation piece 2 provided in the shell 1, and the atomizing core assembly 3 provided on the separation piece 2. The internal structure of the shell 1 is improved to simplify the internal structure of the atomization device and meet the miniaturization design requirement of the shell 1.

[0069] A liquid absorbing cotton 133 is provided on the outer periphery of the air inlet 131 of the lower cover 13, and the liquid absorbing cotton 133 is configured to absorb a leaked liquid matrix.

[0070] In this embodiment, the shell 1 is provided with the air outlet 111. The air outlet 111 is connected to the outside. A user inhales through the air outlet 111.

[0071] In some embodiments of the present disclosure, the separation piece 2 is provided in the shell 1. Specifically, the separation piece 2 is provided within the body of the shell 1. The separation piece 2 can be integrally formed in the shell 1, which simplifies the assembly process of the shell 1; or the separation piece 2 is a separate piece and the separation piece 2 is clamped in the shell 1, or the separation piece 2 is fixed in the shell 1 through a connecting part. For example, the separation piece 2 is detachably arranged in the shell, and the separation piece 2 can be replaced according to the structure of the atomizing core assembly 3.

[0072] The separation piece 2 is arranged in the shell 1 and divides the inner cavity of the shell 1 into the liquid storage chamber 100 and the atomizing chamber 200 in the length direction. The liquid storage chamber 100 is configured to store a liquid matrix, such as e-liquid. The atomizing chamber 200 functions to atomize the liquid matrix.

[0073] In this embodiment, the ventilation hole 4 penetrating in the length direction is formed in the separation piece 2. That is, the ventilation hole 4 is formed at a position where the separation piece 2 is provided.

[0074] In some embodiments of the present disclosure, the ventilation hole 4 is a through hole provided on the separation piece 2, or the ventilation hole 4 is a ventilation hole channel formed between the separation piece 2 and an inner wall of the shell 1.

[0075] In some embodiments of the present disclosure, the ventilation hole 4 is a ventilation hole channel formed between the separation piece 2 and the inner wall of the shell 1. Referring to FIG. 1, FIG. 4 and FIG. 5, the ventilation hole 4 and the separation piece 2 are arranged in the width direction of the shell 1, and the ventilation hole 4 is located at the edge of the separation piece 2 in the width direction of the shell 1.

[0076] In some other embodiments of the present disclosure, the ventilation hole 4 is a through hole provided on the separation piece 2, that is, the ventilation hole 4 and the atomizing core assembly 3 are both provided on the separation piece 2, and the ventilation hole 4 and the atomizing core assembly 3 are staggered in the width direction on the separation piece 2.

[0077] In some other embodiments of the present disclosure, the ventilation hole 4 is a through hole provided on the separation piece 2, that is, the ventilation hole 4 and the atomizing core assembly 3 are both provided on the separation piece 2, the ventilation hole 4 and the atomizing core assembly 3 are staggered in the width direction on the separation piece 2, and the ventilation hole 4 is located between the atomizing core assembly 3 and the inner wall of the shell 1, that is, the ventilation hole 4 is closer to the inner wall of the shell 1 relative to the atomizing core assembly 3.

[0078] In some other embodiments of the present disclosure, the ventilation hole 4 described in this solution can be in two forms: the ventilation hole is directly provided on the separation piece 2, and the ventilation hole is provided on the edge of the separation piece 2 and the inner wall of the shell is used to form the ventilation hole. The ventilation hole 4 refers to a hole structure that is formed on the separation piece 2 and that penetrates in the length direction and can penetrate through two sides of the separation piece 2. Moreover, the ventilation hole 4 is configured to connect the atomizing chamber 200 to the air outlet pipe 5, and does not form direct communication with the liquid storage chamber. The ventilation hole 4 can be connected to the air outlet pipe.

[0079] In this embodiment, the ventilation hole 4 is connected to the atomizing chamber 200, and the liquid matrix in the liquid storage chamber 100 is atomized to form smoke. Air entering from the air inlet 131 carries smoke into the ventilation hole 4, and then can flow to the air outlet 111 for inhaling.

[0080] In this embodiment, the atomization device for an electronic cigarette includes the atomizing core assembly 3. The atomizing core assembly 3 is configured to atomize a liquid matrix transferred to the atomizing core assembly.

[0081] The atomizing core assembly 3 is fixed on the separation piece 2. For example, the atomizing core assembly 3 is fixed on the separation piece 2 through a connecting component, or an accommodating space is formed on the separation piece 2, and the atomizing core assembly 3 is located in the accommodating space, and is clamped in the accommodation space.

[0082] In this embodiment, the ventilation hole 4 penetrating in the length direction is formed on the separation piece 2, the atomizing core assembly 3 is fixed on the separation piece 2, and the atomizing core assembly 3 and the ventilation hole 4 are staggered in the width direction. forming the ventilation hole 4 penetrating in the length direction on the separation piece 2 means that the ventilation hole 4 is a through hole provided on the separation piece 2, or that the ventilation hole 4 is a ventilation hole channel formed between the separation piece 2 and the inner wall of the shell 1.

[0083] In an embodiment where the atomizing core assembly and the ventilation hole are partially staggered, the structure of the ventilation hole in the width direction or the thickness direction may have an irregular shape, and a part of the structure may overlap with the atomizing core assembly in the thickness direction. This method is designed mainly by considering the special layout of the internal structure of the atomization device.

[0084] In an optional embodiment, the atomizing core assembly 3 and the ventilation hole 4 are completely staggered in the width direction of the shell 1. Completely staggering the atomizing core assembly and the ventilation hole can effectively prevent the space in the thickness direction from being occupied.

[0085] Staggering the atomizing core assembly and the ventilation hole can reduce the possibility of the atomizing core assembly 3 and the ventilation hole 4 interfering with each other. Moreover, this structural design can reduce the shared space occupied by the atomizing core assembly and the ventilation hole in the thickness direction, thereby reducing the sizes of the entire atomization device and the shell in the thickness direction, which is conducive to making the atomization device more flat and thinner.

[0086] In the related art, in order to realize that the smoke generated in the atomization device can be inhaled by the user, an upper bracket is provided in the atomization device. The upper bracket is located above the atomizing core assembly and forms a connection relationship with the atomizing core assembly; and a ventilation hole is provided on the upper bracket to allow smoke to enter the air outlet pipe. In the related art, the size of the shell in the thickness direction needs to meet the installation requirements of the atomizing core assembly and the upper bracket at the same time, and consequently the thickness of the shell cannot meet the ultra-thin design requirement.

[0087] In this embodiment, the atomizing core assembly 3 and the ventilation hole 4 are staggered in the width direction of the shell 1, to avoid arranging an additional upper bracket with the ventilation hole 4 in the atomization device. In this embodiment, the atomizing core assembly 3 is fixed on the separation piece 2 of the shell 1. The size of the shell 1 in the thickness direction only needs to meet the installation requirement of the atomizing core assembly 3. The size of the shell 1 in the thickness direction is consistent with the size of the atomizing core assembly 3 in the thickness direction. The size of the shell 1 of the atomization device in the thickness direction meets the ultra-thin design requirement.

[0088] In this embodiment, the upper bracket is eliminated, thereby increasing the internal space of the liquid storage chamber 100. The liquid storage chamber 100 can accommodate more liquid matrices to satisfy user experience.

[0089] In this embodiment, the air outlet pipe 5 is provided in the shell 1. Optionally, the air outlet pipe 5 passes through the liquid storage chamber 100. The air outlet pipe 5 extends roughly in the length direction of the shell 1 (including extending vertically in the length direction of the shell 1, and also including extending obliquely in the length direction of the shell 1). Therefore, the air outlet pipe 5 passes through the liquid storage chamber 100 in the length direction of the liquid storage chamber 100. The air outlet pipe 5 pass through the liquid storage chamber 100 roughly in the width direction of the liquid storage chamber 100.

[0090] In this embodiment, the air outlet pipe 5 connects the air outlet 10 to the ventilation hole 4, and the atomizing chamber 200 is connected to the air outlet 10 through the ventilation hole 4 and the air outlet pipe 5.

[0091] When the user inhales, the sensor of the electronic cigarette is triggered, causing the atomizing core assembly 3 to start heating. The liquid matrix (such as e-liquid) in the liquid storage chamber 100 is transmitted to the atomizing core assembly 3 and is heated and atomized by the atomizing core assembly 3 to form smoke. The outside air enters the atomizing chamber 200 through the air inlet 131, enters the air outlet pipe 5 through the ventilation hole 4, and is then led out by the air outlet pipe 5 into the air outlet for the user to inhale.

[0092] In the embodiments of the present disclosure, the atomization device for an electronic cigarette includes the shell 1, the separation piece 2 and the atomizing core assembly 3. The internal structure of the shell 1 is improved, that is, the ventilation hole 4 penetrating in the length direction is formed on the separation piece 2 in the shell 1, and the atomizing core assembly 3 is fixed on the separation piece 2, so that the atomizing core assembly 3 and the ventilation hole 4 are staggered in the width direction. On the one hand, for the size of the shell 1 in the thickness direction, only the size of the atomizing core assembly 3 in the thickness direction needs to be considered, which satisfies the ultra-thin design requirement of the size of the shell 1 in the thickness direction. On the other hand, the atomizing core assembly 3 is fixed on the separation piece 2, the internal structure of the shell 1 is simplified, and the atomizing core assembly 3 is staggered with the ventilation hole 4, so as to minimize the shared space occupied by the ventilation hole and the air outlet pipe together with the atomizing core assembly 3 in the thickness direction, and the internal space of the liquid storage chamber 100 is enlarged, so that the smoke liquid in the liquid storage chamber 100 can flow into the atomizing core assembly 3 more smoothly. This satisfies user experience.

[0093] In an embodiment, as shown in FIG. 1 to FIG. 5, the separation piece 2 is a separation plate.

[0094] In this embodiment, the separation piece 2 is a separation plate, and the atomizing core assembly 3 is fixed on the separation plate. For example, the separation plate can be integrally formed with the shell 1 or the separation plate and the shell 1 can be connected through a connecting part.

[0095] Referring to FIG. 1, the separation plate is a horizontal plate structure extending in the width direction and the thickness direction of the shell 1.

[0096] In an embodiment, as shown in FIG. 1, a liquid passage hole 21 penetrating in the length direction is formed on the separation piece 2, and the atomizing core assembly 3 blocks the liquid passage hole 21.

[0097] Optionally, a liquid passage hole 21 is formed on the separation piece 2, where the liquid passage hole 21 penetrates in the length direction of the shell 1. One end of the liquid passage hole 21 is connected to the liquid storage chamber 100, and the other end of the liquid passage hole 21 is connected to the atomizing core assembly 3. For example, the liquid matrix in the liquid storage chamber 100 is transmitted to the atomizing core assembly 3 through the liquid passage hole 21, and the liquid matrix is heated and atomized by the atomizing core assembly 3 to form smoke.

[0098] During usage, one end of the liquid passage hole 21 is connected to the liquid storage chamber 100, and the other end of the liquid passage hole 21 is connected to the atomizing core assembly 3. That is, the atomizing core assembly 3 blocks the liquid passage hole 21, so that e-liquid in the liquid storage chamber 100 is transmitted to the liquid suction surface of the atomizing core assembly 3 to prevent the e-liquid in the liquid storage chamber 100 from flowing directly to the air inlet 131 and causing liquid leakage in the atomization device.

[0099] In an embodiment, as shown in FIG. 1, a slot 22 is formed on the separation piece 2, and the atomizing core assembly 3 is fixed in the slot 22.

[0100] In this embodiment, the slot 22 is formed on the separation piece 2, and the atomizing core assembly 3 is fixed in the slot 22, which improves the connection strength between the atomizing core assembly 3 and the separation piece 2. The slot 22 is configured to position and clamp the atomizing core assembly 3. The atomizing core assembly 3 of this solution can be fixedly arranged only through the slot 22 without relying on the cooperation of other components. The position of the slot 22 can correspond to the position of the liquid passage hole 21, and the atomizing core assembly 3 blocks the liquid passage hole 21 to prevent smoke liquid from directly leaking into the atomizing chamber from the liquid passage hole.

[0101] In a specific embodiment, the separation piece 2 includes a transverse plate extending in the width direction and the thickness direction of the shell 1, and the slot 22 is formed by at least two vertical plates connected to the separation piece 2 and extending in the length direction. The slot 22 is formed between the two vertical plates, and the atomizing core assembly 3 is clamped between the two vertical plates.

[0102] In this embodiment, the atomizing core assembly 3 is fixed in the separation piece 2 through the slot 22. Optionally, the atomizing core assembly 3 and the separation piece 2 are in an interference fit, which improves the connection strength between the atomizing core assembly 3 and the separation piece 2.

[0103] In an optional embodiment, as shown in FIG. 1, the slot 22 is located on a side of the separation piece 2 close to the atomizing chamber 200, and the slot 22 is arranged opposite to the liquid passage hole 21.

[0104] Referring to FIG. 1, FIG. 4 and FIG. 5, the slot 22 and the liquid passage hole 21 are arranged in the length direction of the shell 1. The atomizing core assembly 3 is fixed in the slot 22, and a liquid matrix flowing into the liquid passage hole 21 can flow to the liquid suction surface of the atomizing core assembly 3, and then be transmitted to an atomizing surface of the atomizing core assembly 3. The liquid matrix is atomized to form smoke.

[0105] In an optional embodiment, as shown in FIG. 1, FIG. 4 and FIG. 5, the ventilation hole 4 is located between the atomizing core assembly 3 and the inner wall of the shell 1 in the width direction, that is, the ventilation hole 4 is closer to the inner wall of the shell 1 than the atomizing core assembly 3.

[0106] Referring to FIG. 1, FIG. 4 and FIG. 5, in the width direction of the shell 1, the ventilation hole 4 is arranged adjacent to the atomizing core assembly 3. The ventilation hole 4 is located on the right side of the atomizing core assembly 3. In another embodiment, the ventilation hole 4 is arranged adjacent to the atomizing core assembly 3 in the width direction, and the ventilation hole 4 is located on the left side of the atomizing core assembly 3. This embodiment does not limit the specific position of the ventilation hole 4, as long as the atomizing core assembly and the ventilation hole are staggered in the width direction, and the ventilation hole 4 is closer to the inner wall of the shell 1 than the atomizing core assembly 3.

[0107] Referring to FIG. 1, FIG. 4 and FIG. 5, the right edge of the separation piece 2 and the inner surface of the shell 1 together form the ventilation hole 4. The lower cover 13 of the shell 1, the inner surface of the shell 1 and the atomizing surface of the atomizing core assembly 3 form the atomizing chamber 200. The ventilation hole 4 is connected with the atomizing chamber 200, and the liquid matrix is atomized to form smoke, and the smoke enters the atomizing chamber 200, enters the air outlet pipe 5 through the ventilation hole 4, and then enters the air outlet 111 to be inhaled by the user. Using the inner surface of the shell and the separation piece to jointly form the ventilation hole can minimize the space occupied to form the structure of the ventilation hole in the width direction, and effectively utilize the space as a part of the air path. In other embodiments, the ventilation hole can also be directly provided on the separation piece without using the inner surface of the shell.

[0108] In an embodiment, the separation piece 2 is integrally formed with the shell 1.

[0109] In this embodiment, the separation piece 2 is integrally formed with the shell 1 and is injection molded together with the shell. This method can simplify the assembly of the separation piece, make the positioning more accurate, and make it easy to fix the atomizing core assembly.

[0110] In a specific embodiment, the shell 1 includes a body of the shell 1 and a lower cover 13 covering the body of the shell 1. The body of the shell 1 is integrally formed. The separation piece 2 is integrally formed with the body of the shell 1.

[0111] In another specific embodiment, the shell 1 includes the body of the shell 1 and a lower cover 13 covering the body of the shell 1. The body of the shell 1 includes an upper shell 11 and a lower shell 12. The lower shell 12 and the upper shell 11 form a connection relationship. The upper shell 11 and the lower shell 12 are formed separately, and the separation piece 2 is integrally formed with the lower shell 12.

[0112] In an embodiment, as shown in FIG. 1, the air outlet 111 is located on an end surface of one end of the shell 1 in the length direction. The air outlet 111 is arranged at this position to facilitate the user inhaling and usage.

[0113] In this embodiment, the air outlet 111 is located at the top end of the shell 1 in the length direction to facilitate the user to inhale through the air outlet 111. Specifically, the air outlet 111 is located at the top end of the shell 1 in the length direction, and is located at the center of the top end of the shell 1. Therefore, the structure of the atomization device is more aesthetic.

[0114] In an embodiment, the atomizing chamber 200 and the air outlet pipe 5 are a gas path area of the atomization device for an electronic cigarette, and the liquid storage chamber 100 is a liquid path area of the atomization device for an electronic cigarette.

[0115] In the shell 1, a ventilation channel 7 connecting the gas path area to the liquid path area is formed on the shell 1, and the ventilation channel 7 allows gas in the gas path area to enter the liquid path area and prevents liquid in the liquid path area from entering the gas path area.

[0116] In this embodiment, the atomizing chamber 200 and the air outlet pipe 5 are the air path area of the atomization device for an electronic cigarette. Specifically, outside air enters the atomizing chamber 200 through the air inlet 131, and the liquid matrix is atomized to form smoke. The smoke and the air entering the atomizing chamber 200 enter the air outlet pipe 5 through the ventilation hole 4, and enter the air outlet 111 through the air outlet pipe 5. The user can implement the inhaling process through the air outlet 111.

[0117] In this embodiment, the liquid storage chamber 100 is the liquid path area of the atomization device for an electronic cigarette. Specifically, a liquid matrix is stored in the liquid storage chamber 100. The liquid matrix is absorbed by the liquid suction surface of the atomizing core assembly 3 through the liquid passage hole 21 and then transmitted to the atomizing surface of the atomizing core assembly 3. The atomizing surface atomizes the liquid matrix to form smoke in the atomizing chamber 200.

[0118] In this embodiment, the ventilation channel 7 is formed on the shell 1 to connect the gas path area to the liquid path area. Since the smoke liquid in the liquid storage chamber 200 gradually penetrates the atomizing core assembly and is vaporized, the air pressure in the liquid storage chamber 200 gradually decreases with the usage of the electronic cigarette. When the air pressure of the atomizing chamber 200 is higher than the air pressure of the liquid storage chamber 100, the outside air enters the liquid storage chamber 100 through the ventilation channel 7 to achieve the air pressure balance between the atomizing chamber 200 and the liquid storage chamber 100, so that the liquid matrix in the liquid storage chamber 100 can flow to the atomizing core assembly 3.

[0119] In an embodiment, a one-way ventilation seal is provided in the atomization device, and the one-way ventilation seal is configured to block the ventilation channel 7.

[0120] The one-way ventilation seal is configured to release blocking of the ventilation channel 7 when a pressure in the gas path area is greater than a pressure in the liquid path area.

[0121] In a specific embodiment, when the user inhales, the sensor in the electronic cigarette is triggered and sends a signal to drive the atomizing core assembly 3 to start heating. The liquid matrix is heated and atomized in the atomizing surface, and at the same time, the outside air passes through the air inlet 131 of the lower cover 13 and enters the atomizing chamber 200, and the air entering the atomizing chamber 200 mixes with the heated smoke in the atomizing chamber 200. After mixing, the aerosol smoke passes through the ventilation hole 4, the air outlet pipe 5 and then enters the user mouth through the air outlet 111. As the smoke is generated, the e-liquid is gradually adsorbed to a side of the atomizing surface by the atomizing core assembly 3. The liquid matrix on the side of the oil storage cavity is reduced, which causes the air pressure to drop, forming a negative pressure. The air pressure on one side of the atomizing chamber 200 is higher, and the outside air pushes the one-way ventilation seal through the ventilation channel 7 and flows into the liquid storage chamber 100 to achieve air pressure balance. After the air pressure of the atomizing chamber 200 and the liquid storage chamber 100 is balanced, the one-way ventilation seal returns to its original state, that is, the one-way ventilation seal blocks the ventilation channel 7, thereby preventing the liquid matrix in the liquid storage chamber 100 from leaking from the ventilation channel 7. Furthermore, the atomizing core assembly 3 can adsorb sufficient smoke oil to maintain the smoke generation effect.

[0122] In an embodiment, as shown in FIG. 1, the atomizing core assembly 3 includes an atomizing core 30 and an atomizing core seal 31 sleeved around the atomizing core 30, and the atomizing core seal 31 is in an interference fit with the separation piece 2 and the atomizing core 30 respectively.

[0123] The ventilation channel 7 is provided between the separation piece 2 and the atomizing core seal 31, and at least a part of structure of the atomizing core seal 31 serves as the one-way ventilation seal.

[0124] In this embodiment, the atomizing core assembly 3 includes the atomizing core 30 and the atomizing core seal 31 sleeved on the outer periphery of the atomizing core 30. When the atomizing core assembly 3 is fixed on the separation piece 2, the atomizing core seal 31 is in an interference fit with the separation piece 2.

[0125] In this embodiment, the ventilation channel 7 is provided between the separation piece 2 and the atomizing core seal 31. For example, the ventilation channel 7 may be formed on the separation piece 2. Alternatively, the ventilation channel 7 can be formed on the atomizing core seal 31.

[0126] When the atomizing core assembly 3 is fixed on the separation piece 2, the atomizing core seal 31 is in an interference fit with the separation piece 2, and at least a part of the structure of the atomizing core seal 31 serves as the one-way ventilation seal. For example, the separation piece is a separation plate, and vertical plates are arranged at intervals on a side of the atomizing chamber. The two vertical plates form the slot 22, and the atomizing core assembly 3 is fixed in the slot 22. The ventilation channel 7 is formed on the vertical plate, and the side wall portion of the atomizing core seal 31 forms the one-way ventilation seal. The atomizing core seal 31 serves as a component for determining whether the ventilation channel 7 is in a connected state or a blocked state. The ventilation channel 7 may be a groove provided on the vertical plate, and the groove extends in the length direction. Alternatively, the ventilation channel 7 may also be a through hole provided on the vertical plate and penetrating through the vertical plate in the width direction.

[0127] In an embodiment, as shown in FIG. 3, the ventilation channel 7 is a ventilation groove 71 provided on the separation piece 2.

[0128] In this embodiment, the ventilation channel 7 is the ventilation groove 71 provided on the separation piece 2. For example, the separation piece 2 is made of a hard material, and the ventilation channel 7 is provided on the separation piece 2, which reduces the difficulty of providing the ventilation channel 7. Moreover, the depth of the ventilation groove 71 is relatively shallow. Due to the surface tension of the liquid, the smoke liquid in the liquid storage chamber does not easily enter the atomizing chamber in the reverse direction through the ventilation groove 71. This design improves liquid leakage resistance performance.

[0129] In an embodiment, as shown in FIG. 1, the slot 22 is formed on the separation piece 2, the atomizing core assembly 3 is fixed on the slot 22, the ventilation groove 71 is provided on an inner surface of a side wall of the slot 22, the ventilation groove 71 extends in the length direction, and an upper edge of a side wall of the atomizing core seal 31 serves as the one-way ventilation seal.

[0130] In this embodiment, two vertical plates are formed on the separation piece 2, and the two vertical plates are arranged at intervals in the width direction of the shell 1. The two vertical plates form the slot 22 of the separation piece 2. The atomizing core 30 is fixed between the two vertical plates, that is, the atomizing core assembly 3 is fixed in the slot 22.

[0131] In this embodiment, the ventilation groove 71 is provided on an inner surface of a side wall of the slot 22, and the ventilation groove 71 extends in the length direction. Herein, the atomizing core seal 31 disposed opposite to the ventilation groove 71 in the width direction of the shell 1 serves as the one-way ventilation seal. Specifically, the upper edge portion of the side wall of the atomizing core seal 31 arranged opposite to the ventilation groove 71 serves as the one-way ventilation seal.

[0132] Specifically, the ventilation groove 71 is a recessed groove provided on the inner surface of the slot 22. The ventilation groove 71 extends in the length direction of the shell 1 to facilitate external air enter the liquid storage chamber 100 through the ventilation groove 71 to balance the air pressures of the liquid storage chamber 100 and the atomizing chamber 200.

[0133] In some embodiments of the present disclosure, the separation piece 2 includes a top plate and the side wall extending from the top plate toward the atomizing chamber 200, the top plate and the side wall together form the slot 22, the top plate is provided with the liquid passage hole 21, and the atomizing core seal 31 is in an interference fit with the top plate and/or the side wall.

[0134] In some embodiments of the present disclosure, the air outlet pipe 5 includes a first air outlet pipe and a second air outlet pipe that are in communication with each other, the first air outlet pipe is connected to the ventilation hole 4, and the second air outlet pipe is connected to the air outlet 111.

[0135] In an optional embodiment, as shown in FIG. 1, the first air outlet pipe is an air outlet vertical pipe 51, the air outlet vertical pipe 51 extends in the length direction, and the air outlet vertical pipe 51 is staggered from the atomizing core assembly 3 in the width direction.

[0136] In this embodiment, the air outlet pipe 5 includes an air outlet vertical pipe 51, and the air outlet vertical pipe 51 extends in the length direction of the shell 1. One end of the air outlet vertical pipe 51 is directly connected to the ventilation hole 4, and the other end of the air outlet vertical pipe 51 is indirectly connected to the air outlet 111.

[0137] The air outlet vertical pipe 51 is staggered from the atomizing core assembly 3 in the width direction of the shell 1. For example, the air outlet vertical pipe 51 and the atomizing core assembly 3 are partially staggered in the width direction of the shell 1. Alternatively, the air outlet vertical pipe 51 and the atomizing core assembly 3 are completely staggered in the width direction of the shell 1. Referring to FIG. 1, FIG. 4 and FIG. 5, the air outlet vertical pipe 51 and the atomizing core assembly 3 are completely staggered in the width direction.

[0138] In this embodiment, the air outlet vertical pipe 51 and the atomizing core assembly 3 are staggered in the width direction to prevent the air outlet vertical pipe 51 from occupying the internal space of the liquid storage chamber 100, so that more liquid matrices can be stored inside the liquid storage chamber 100. Besides, in this embodiment, the air outlet vertical pipe 51 is only arranged on a side of the shell 1, and there is no need to provide an additional upper bracket with the ventilation hole 4. When setting the size of the shell 1 in the thickness direction, only the thickness of the atomizing core assembly 3 needs to be considered. In this way, the thickness of the shell 1 can be reduced.

[0139] In an embodiment, as shown in FIG. 1, in the width direction, the air outlet vertical pipe 51 is located adjacent to the inner wall of the shell 1.

[0140] In an embodiment, as shown in FIG. 1 and FIG. 4, the air outlet vertical pipe 51 is integrally formed with the shell 1. That is, the air outlet vertical pipe 51 is directly formed in the shell 1. In a specific embodiment, as shown in FIG. 1, in the width direction of the shell 1, the shell 1 is provided with a first side wall, a second side wall adjacent to the first side wall, and a third side wall adjacent to the second side wall. The first side wall, the second side wall, and the surface of the shell 1 together form the air outlet vertical pipe 51, and the second side wall, the third side wall, and the surface of the shell 1 form the liquid storage chamber 100.

[0141] Relative to the liquid storage chamber 100, the inner surface of the first side wall forms a surface of the air outlet vertical pipe 51. The air outlet vertical pipe 51 in this embodiment is formed in a simple manner, which reduces the assembly process of the shell 1. Furthermore, the inner cavity space in the shell is almost not occupied by the air outlet vertical pipe, and the air outlet vertical pipe only occupies the edge position. This design facilitates the layout inside the atomization device.

[0142] In an embodiment, the air outlet vertical pipe 51 is a separate piece. In this embodiment, there is a gap between the air outlet vertical pipe 51 and the inner surface of the first side wall, which facilitates the assembly and disassembly of the air outlet vertical pipe 51. Relative to the liquid storage chamber 100, in this embodiment, the air outlet vertical pipe 51 is disposed closer to the inner surface of the first side wall. Using a separate piece to form the air outlet vertical pipe 51 can simplify the internal structure of the shell and reduce the difficulty of the injection molding process of the shell.

[0143] In other optional embodiments, the air outlet vertical pipe can also be replaced by a pipe that extends in a bending manner.

[0144] In an optional embodiment, as shown in FIG. 1, the second air outlet pipe is an inclined pipe 52 extending in the length direction of the shell 1, and the inclined pipe 52 is formed on the shell 1.

[0145] In the width direction, there is a predetermined distance between the air outlet 111 and the air outlet vertical pipe 51. The offset distance in this part is connected by the inclined pipe 52 in the width direction.

[0146] In this embodiment, the air outlet pipe 5 includes the inclined pipe 52, and the inclined pipe 52 is connected between the air outlet vertical pipe 51 and the air outlet 111. For example, the aerosol smoke enters the ventilation hole 4, passes through the air outlet pipe 5 and the inclined pipe 52, and then enters the air outlet 111 for the user to inhale.

[0147] In this embodiment, the inclined pipe 52 is formed on the shell 1. For example, the inclined pipe 52 is integrally formed with the shell 1. For example, in the width direction of the shell 1, the shell 1 includes a first side wall, a second side wall adjacent to the first side wall, and a third side wall adjacent to the second side wall. The second side wall, the third side wall and the surface of the shell 1 together form the liquid storage chamber 100. The second side wall includes an inclined side wall. The inclined side wall and the surface of the shell 1 form the inclined pipe 52. In an embodiment, the shell 1 is injection molded by means of a mould. In order to facilitate the formation of the inclined pipe 52 on the shell 1, the body of shell 1 is divided into the upper shell 11 and the lower shell 12. The inclined pipe 52 is formed on the upper shell 11.

[0148] In this embodiment, there is a predetermined distance between the air outlet 111 and the air outlet vertical pipe 51 in the width direction of the shell 1. For example, the air outlet 111 is located in the middle of the top end of the shell 1, and the air outlet vertical pipe 51 is arranged closer to the inner surface of the first side wall of the shell 1. The air outlet 111 and the air outlet vertical pipe 51 are connected through the inclined pipe 52.

[0149] In this embodiment, the air outlet pipe 5 includes the air outlet vertical pipe 51 and the inclined pipe 52 connected to the air outlet vertical pipe 51. The aerosol smoke passes through the air outlet vertical pipe 51, enters the inclined pipe 52, and finally enters the air outlet 111 for the user to inhale. In the related art, the aerosol smoke directly enters the air outlet 111 through the vertical air outlet pipe 5 for the user to inhale. Compared with the related art, the air outlet pipe 5 designed in the embodiments of the present disclosure can better satisfy the user experience. The inclined extension of the inclined pipe 52 helps air and smoke flow out, has relatively small resistance and brings better inhaling experience for the user. Moreover, the inclined pipe is easy to be integrally formed in the shell, and the processing technology is relatively easy to implement.

[0150] In some embodiments of the present disclosure, the air outlet vertical pipe 51 is formed on the shell 1 and integrally formed with the inclined pipe 52.

[0151] In some embodiments of the present disclosure, a baffle is formed on the shell 1, and the baffle separates the inner cavity of the shell 1 into the liquid storage chamber 100 and the air outlet pipe 5 in the length direction.

[0152] In some embodiments of the present disclosure, the first air outlet pipe is a connecting pipe provided in the shell 1.

[0153] In some embodiments of the present disclosure, the connecting pipe is an elbow pipe or a straight pipe, the second air outlet pipe is formed on the shell 1, a first end of the connecting pipe is inserted into the ventilation hole 4, and a second end of the connecting pipe is inserted into an inner surface of an end of the second air outlet pipe away from the air outlet 111.

[0154] In some embodiments of the present disclosure, there is a seal sleeve between an outer circumferential surface of the first end of the connecting pipe and an inner circumferential surface of the ventilation hole 4, and/or there is a seal sleeve between an outer circumferential surface of the second end of the connecting pipe and an inner surface of an end of the second air outlet pipe away from the air outlet 111.

[0155] In some embodiments of the present disclosure, the connecting pipe is a hose, the ventilation hole 4 is a ventilation hole channel formed between the separation piece 2 and the inner wall of the shell 1, one end of the hose is sleeved on an outer circumferential surface of an end of the ventilation hole channel facing the air outlet 111, and the other end of the hose is sleeved on an outer surface of an end of the second air outlet pipe away from the air outlet 111.

[0156] In some embodiments of the present disclosure, the shell 1 includes a shell body and a lower cover 13, the lower cover 13 is arranged to cover an end of the shell body away from the air outlet 111 to form a sealed connection, an air inlet 131 is formed on the lower cover 13, and the air inlet 131 is connected to the atomizing chamber 200.

[0157] In an embodiment, as shown in FIG. 1, the shell body includes an upper shell 11 and a lower shell 12, the upper shell 11 is connected to the lower shell 12 in a sealed manner, and the air outlet 111 is provided on the upper shell 11.

[0158] In this embodiment, the shell 1 includes the upper shell 11 and the lower shell 12, and the upper shell 11 and the lower shell 12 are formed separately. The upper shell 11 and the lower shell 12 are accurately connected to form seal, which facilitates arrangement of the air outlet pipe 5 on the upper shell 11 and the lower shell 12 respectively, so that the air outlet pipes 5 inside the upper shell 11 and the lower shell 12 can be formed separately.

[0159] The separated upper shell 11 and the lower shell 12 reduce the processing difficulty of the atomization device, and the air outlet pipe 5, separation piece 2 and other components in the shell 1 are easier to arrange and form. Moreover, it is easier to form the liquid storage chamber 100 and the air outlet pipe 5 in the shell 1 into required shapes.

[0160] In this embodiment, when the upper shell 11 and the lower shell 12 are respectively formed, the air outlet 111 is provided at the top end of the upper shell 11. Optionally, the air outlet 111 is located in the middle of the upper shell 11 in the width direction, that is, the air outlet 111 is located in the middle of the top end of the upper shell 11. This design method ensures aesthetic beauty and is convenient for users to inhale. In other methods, the air outlet may also be located on a side surface of the top end of the upper shell, for example, located on the edge on a side of the top end of the upper shell in the width direction.

[0161] In an embodiment, the separation piece 2 is provided in the lower shell 12; the upper shell 11, the lower shell 12 and the separation piece 2 together form the liquid storage chamber 100; and the lower shell 12, the separation piece 2, the atomizing core assembly 3 and the lower cover 13 together form the atomizing chamber 200.

[0163] In this embodiment, the upper shell 11, a part of the lower shell 12 and the separation plate together form the liquid storage chamber 100. Compared with the related art, this embodiment increases the internal space of the liquid storage chamber 100.

[0164] In an embodiment, a junction between the upper shell 11 and the lower shell 12 is configured to be sealed by ultrasonic welding or sealed by snap fasteners.

[0165] In this embodiment, the junction between the upper shell 11 and the lower shell 12 forms a sealed connection after ultrasonic welding. On the basis of ensuring the connection strength between the upper shell 11 and the lower shell 12, sealing between the upper shell 11 and the lower shell 12 is improved. The ultrasonic welding process can fuse the materials of the upper shell 11 and the lower shell 12 together to prevent the liquid in the liquid storage chamber 100 from leaking.

[0166] In a specific embodiment, at the junction between the upper shell 11 and the lower shell 12, the end surface of the upper shell 11 and the end surface of the lower shell 12 are connected, and the inner circumferential surface of the upper shell 11 and the outer circumferential surface of the lower shell 12 are connected. For example, a junction between end faces of the upper shell and the lower shell and/or a junction between circumferential surfaces of the upper shell and the lower shell can be sealed by ultrasonic welding.

[0167] In an embodiment, as shown in FIG. 1, a first seal ring 81 is provided at the junction between the upper shell 11 and the lower shell 12.

[0168] In an embodiment, the first seal ring 81 is provided at the junction between the circumferential surfaces of the upper shell 11 and the lower shell 12, and the junction between the end surfaces of the upper shell 11 and the lower shell 12 is connected by ultrasonic welding.

[0170] In this embodiment, the junction between the upper shell 11 and the lower shell 12 is connected through a combination of the seal ring and ultrasonic welding, which improves the connection reliability and sealing performance of the upper shell 11 and the lower shell 12.

[0171] In an embodiment, as shown in FIG. 1, a positioning end surface 112 and a surrounding edge 113 are formed at a lower end of the upper shell 11, the surrounding edge 113 is located on the periphery of the positioning end surface 112, and in the length direction, the positioning end surface 112 is closer to the air outlet 111 than the surrounding edge 113.

[0172] A top end of the lower shell 12 is inserted on an inner side of the surrounding edge 113 and abuts against the positioning end surface 112.

[0173] In this embodiment, the positioning end surface 112 is arranged closer to the air outlet 111 than the surrounding edge 113, so that the surrounding edge 113 is arranged closer to the lower shell 12 than the positioning end surface 112.

[0174] In this embodiment, the surrounding edge 113 and the positioning end surface 112 cooperate to form a stepped annular structure. When the upper shell 11 and the lower shell 12 are sealed and connected, the top end of the lower shell 12 can be inserted on an inner side of the surrounding edge 113, so that accurate alignment is formed between the upper shell 11 and the lower shell 12. After the top end of the lower shell 12 abuts against the positioning end surface 112, the upper shell 11 and the lower shell 12 are connected desirably, thereby implementing accurate assembly between the upper shell 11 and the lower shell 12.

[0175] By providing the positioning end surface 112 and the surrounding edge 113 on the upper shell 11, the connection reliability and sealing between the upper shell and the lower shell 12 can be effectively improved. On the one hand, the surrounding edge 113 functions to position the upper shell and the lower shell 12 to prevent misalignment between the upper shell and the lower shell, and connects to the lower shell 12 from the surrounding to improve the connection reliability. On the other hand, the surrounding edge 113 extends a docking gap between the upper shell and the lower shell 12 and further prevents air and liquid from leaking from the junction.

[0176] In other optional implementations, the surrounding edge can be formed on the lower shell, and the lower end of the upper shell is inserted within the surrounding edge of the lower shell.

[0177] In an embodiment, as shown in FIG. 1, a seal groove is formed on an outer peripheral side surface of the top end of the lower shell 12; and a first seal ring 81 is embedded in the seal groove; where the first seal ring 81 is in an interference fit with the seal groove and an inner side surface of the surrounding edge 113.

[0178] In this embodiment, a seal groove is provided on the outer peripheral side surface of the lower shell 12 close to the top end of the lower shell. The first seal ring 81 is embedded in the seal groove. That is, in this embodiment, the junction between the circumferential surfaces of the upper shell 11 and the lower shell 12 is connected through the first seal ring 81. The junction between the end faces of the upper shell 11 and the lower shell 12 is sealed by ultrasonic welding.

[0179] After the upper shell 11 and the lower shell 12 are accurately connected, inner side surfaces of the first seal ring 81, the seal groove and the surrounding edge 113 are in an interference fit, further improving the connection reliability between the upper shell 11 and the lower shell 12. In particular, through implementation of the combination of the first seal ring and ultrasonic welding, the connection reliability and sealing between the upper shell and the lower shell can be more effectively improved. For example, preferably, a seal groove and a first seal ring are provided on the outer peripheral side surface of the lower shell, and an ultrasonic welding line is formed between the top end surface of the lower shell and the positioning end surface of the upper shell. This method can not only ensure the connection and positioning reliability, but also improve the sealing performance through the effect of the seal ring and the surrounding edge. In this method, a first sealing barrier is the ultrasonic welding line, and a second sealing barrier is the first seal ring. Furthermore, the ultrasonic welding line and the first seal ring complement each other to provide a positioning connection function.

[0180] In other optional implementations, the first seal ring 81 may also be provided on the positioning end surface, and the ultrasonic welding line is formed at the junction surrounding the side wall.

[0181] In an embodiment, as shown in FIG. 4, in the length direction, a height of the middle area of the first seal ring 81 in the width direction is lower than heights of two end areas of the first seal ring 81 in the width direction.

[0182] In this embodiment, the height of the middle area of the first seal ring 81 in the width direction is lower than the heights of the two end areas of the first seal ring 81 in the width direction. Specifically, a circle of reference line is provided on the first seal ring 81. A distance between the middle area of the first seal ring 81 and the reference line is a first distance. A distance between one of the two end areas of the first seal ring 81 and the reference line is a second distance, where the first distance is greater than the second distance.

[0183] When the upper shell is formed, the upper shell 11 has an area of the shell 1 corresponding to the middle area of the first seal ring 81. In this embodiment, the position of the middle area of the first seal ring 81 in the width direction and the positions of the two end areas of the first seal ring 81 in the width direction are defined, to better match the shape of the upper shell 11. This provides good sealing performance for the upper shell and the lower shell while making full use of the accommodation space of the upper shell. In some preferred implementations, the upper shell is usually made such that the length of the middle area in the width direction is large and the lengths of the two end areas are small. This design is to ensure the stability of the injection molding structure of the upper shell and avoid an excessively thin wall in a local area caused by uneven flow of an injection molding material. Designing the first seal ring into a shape that matches this structural feature is conducive to making full use of the shape feature of the upper shell.

[0184] In an embodiment, the air outlet pipe 5 is integrally formed in the shell 1.

[0185] In this embodiment, the air outlet pipe 5 is integrally formed with the shell 1, which reduces the assembly process of the shell 1.

[0186] In an embodiment, as shown in FIG. 1, the air outlet pipe 5 is integrally formed in the shell 1, the upper shell 11 has an upper air outlet pipe 53, the lower shell 12 has a lower air outlet pipe 54, and the upper air outlet pipe 53 and the lower air outlet pipe 54 are connected to jointly form the air outlet pipe 5.

[0187] In this embodiment, a part of the air outlet pipe 5 is provided in the upper shell 11, and a part of the air outlet pipe 5 is provided in the lower shell 12. For example, the air outlet pipe 5 provided in the upper shell 11 is the upper air outlet pipe 53. The air outlet pipe 5 provided in the lower shell 12 is the lower air outlet pipe 54. The upper shell 11 and the lower shell 12 are accurately connected to form seal, and the upper air outlet pipe 53 and the lower air outlet pipe 54 are connected to jointly form the air outlet pipe 5.

[0188] In this embodiment, the upper air outlet pipe 53 and the lower air outlet pipe 54 are formed on the upper shell 11 and the lower shell 12 respectively. For example, the upper air outlet pipe 53 is formed inside the upper shell 11 by injection molding, and the lower air outlet pipe 54 is formed inside the lower shell 12 by injection molding.

[0189] In this embodiment, the air outlet pipe 5 is formed in the upper shell 111 and the lower shell 122 respectively, which can simplify the processing technology of the air outlet pipe 5 and avoid the difficulty of injection molding of the air outlet pipe 5.

[0190] In an embodiment, as shown in FIG. 2, a slot is formed at a lower end of the upper air outlet pipe 53, a pipe plug is formed at a top end of the lower air outlet pipe 54, and the pipe plug is fixedly inserted in the slot.

[0191] In this embodiment, the slot is formed at the lower end of the upper air outlet pipe 53, and the pipe plug is formed at the top end of the lower air outlet pipe 54. The upper air outlet pipe 53 and the lower air outlet pipe 54 are connected by the cooperation between the slot and the pipe plug, to form the air outlet pipe 5.

[0192] Alternatively, in another embodiment, the pipe plug is formed at the lower end of the upper air outlet pipe 53, and the slot is formed at the top end of the lower air outlet pipe 54. The upper air outlet pipe 53 and the lower air outlet pipe 54 are connected by the cooperation between the slot and the pipe plug, to form the air outlet pipe 5.

[0193] In this embodiment, the connection method of the upper air outlet pipe 53 and the lower air outlet pipe 54 is simple, which facilitates the assembly and cooperation of the upper air outlet pipe 53 and the lower air outlet pipe.

[0194] In an embodiment, as shown in FIG. 1, a second seal ring 82 is sleeved on the pipe plug, and the second seal ring 82 is in an interference fit between the pipe plug and the slot.

[0195] In this embodiment, the second seal ring 82 is sleeved on the pipe plug. When the pipe plug and the slot cooperate, the second seal ring 82 are in an interference fit with the pipe plug and the slot, thereby preventing air leakage in the air outlet pipe 5 formed by combining the upper air outlet pipe 53 and the lower air outlet pipe 54.

[0196] In an optional embodiment, referring to FIG. 4, in a direction from the air outlet 111 to the lower shell 12, a size of the upper shell 11 in the thickness direction gradually increases.

[0197] in the length direction, a size of the middle area of the upper shell 11 in the width direction is larger than sizes of the two end areas of the upper shell 11 in the width direction.

[0198] In this embodiment, the upper shell 11 is formed by injection molding. During the injection molding process, in a direction from the air outlet 111 to the lower shell 12, a size of the upper shell 11 in the thickness direction gradually increases. When the user inhales through the air outlet 111, the mouth of the user holds the air outlet 111. Since the thickness of the upper shell 11 at the air outlet 111 is the smallest, the user experience is improved.

[0199] Optionally, in this embodiment, in the length direction, a size of the middle area of the upper shell 11 in the width direction is larger than sizes of two end areas of the upper shell 11 in the width direction. The shell has the feature that the size in the thickness direction gradually changes. Therefore, during the injection molding process, the upper shell 11 is prone to uneven wall thicknesses caused by uneven flow of an injection molding material. This process feature even causes holes in the upper shell. In order to avoid this defect, in this solution, the size of the upper shell in the length direction can be designed such that the two ends are short and the middle is long in the width direction, thereby avoiding that the top end area of the upper shell is excessively thin, and avoiding the impact on the shell quality.

[0200] When the upper shell 11 and the lower shell 12 are connected, and the end faces of the upper shell 11 and the lower shell 12 are connected by ultrasonic welding, the middle area of the formed ultrasonic line can form a downwardly bent arc relative to the two end areas.

[0201] In an embodiment, the top end surface of the upper shell 11 is an arc surface.

[0202] In this embodiment, the top end surface of the upper shell 11 is an arc surface, making the structure of the atomization device more beautiful. Besides, the top end surface of the upper shell 11 is arranged as an arc surface, and the air outlet 111 is formed on the top end surface. The mouth of the user holds the air outlet 111, and the user has a better experience when inhaling.

[0203] In an embodiment, as shown in FIG. 5, the upper shell 11 is divided into an upper shell body and a top cover 9, the top cover 9 is provided to cover a top end of the upper shell body, and the air outlet 111 is formed on the top cover 9.

[0204] The air outlet pipe 5 includes an inclined pipe 52, an inclined baffle 115 is formed on the upper shell body, and the inclined baffle 115 and the top cover 9 together form the inclined pipe 52.

[0205] In this embodiment, the upper shell 11 includes an upper shell body 1011 and a top cover 91. The top cover 9 can be set to different colors to match the upper shell body. The top cover 9 has different appearances to match the upper shell body, making the structure of the atomization device more beautiful.

[0206] In this embodiment, the air outlet pipe 5 includes an inclined pipe 52, and an inclined baffle 115 is formed on the upper shell body. The inclined baffle 115 and the top cover 9 together form the inclined pipe 52, which reduces the demolding difficulty of injection molding of the inclined pipe 52 in the shell 1. The demolding difficulty of the oblique core on the upper shell 11 can be reduced to the demolding difficulty of the upper shell 11.

[0207] In an embodiment, an internal positioning rib 114 extending in the length direction is formed in the upper shell 11 and/or the lower shell 12.

[0208] The inner positioning rib 114 is attached on an inner surface of the lower shell 12 that is not directly connected to the inner positioning rib and/or an inner surface the upper shell 11 that is not directly connected to the inner positioning rib.

[0209] In this implementation, as shown in FIG. 1, FIG. 4 and FIG. 5, the inner positioning rib 114 extending in the length direction is formed in the upper shell 11, and the inner positioning rib 114 is attached on the inner surface of the upper shell 11 that is not directly connected to the inner positioning rib. When the upper shell 11 and the lower shell 12 are close to each other, the inner positioning rib 114 can implement quick docking of the upper shell 11 and the lower shell 12. The inner positioning rib 114 can also form a guide for the upper shell 11 when the upper shell 11 and the lower shell 12 are connected, ensuring the accuracy of the docking of the upper shell 11 and the lower shell 12.

[0210] In an embodiment, the ventilation hole 4 and the atomizing core assembly 3 are completely staggered in the width direction.

[0211] In this embodiment, the ventilation hole 4 and the atomizing core assembly 3 are completely staggered in the width direction, that is, the ventilation hole 4 and the atomizing core assembly 3 are arranged adjacent to each other in the width direction. When the ventilation hole 4 and the atomizing core assembly 3 are arranged adjacent to each other in the width direction, the ventilation hole 4 does not occupy the internal space of the liquid storage chamber 100 at all, thereby increasing the internal storage space of the liquid storage chamber 100.

[0212] According to a second aspect of the embodiments of the present disclosure, an electronic cigarette is provided. The electronic cigarette includes:

a cigarette rod, an electrical component being arranged in the cigarette rod, and the cigarette rod having an accommodating groove with a top end that is open; and

[0213] In this embodiment, the atomizing core assembly 3 can form an electrical connection with the electrical component through a conductive nail 6. The electrical component can supply power to a heating element of the atomizing core assembly 3 through the conductive nail 6.

[0214] When the user uses the electronic cigarette, the user inhales through the air outlet 111. The external air enters the atomizing chamber 200 through the air inlet 131. The sensor in the electronic cigarette senses the inhaling action of the user, and the electrical connection between the electrical component and the heating element is conducted to supply power to the heating element to heat and atomize the liquid in the liquid storage chamber 100 to form smoke, and the air enters the atomizing chamber 200 to drive the smoke to be inhaled by the user through the air outlet pipe 5 and the air outlet 111, to ensure the user inhaling experience.

[0215] The above embodiments focus on describing differences between the embodiments, and different optimization features of the embodiments may be combined to form better embodiments provided that they are not contradictory. Considering brevity, details are not described herein again.
