| (54) | E-LIQUID CORE SEPARATION STRUCTURE, ATOMIZATION APPARATUS, AND ATOMIZATION DEVICE |
| (57) The present application discloses an e-liquid core separation structure, an atomization
device, and atomization equipment, relating to the field of atomization technology.
The e-liquid core separation structure includes an e-liquid cup body, an atomization
assembly, and an e-liquid inlet switch. The atomization assembly is mounted in the
e-liquid cup body. The e-liquid cup body is provided with a first chamber, a second
chamber, a first e-liquid inlet hole, and a second e-liquid inlet hole. The first
chamber is used for storing e-liquid and is communicated with the second chamber through
the first e-liquid inlet hole. The second chamber is communicated with the e-liquid
storage cotton of the atomization assembly through the second e-liquid inlet hole.
The e-liquid inlet switch is mounted in the e-liquid cup body and is used to open
or close the first e-liquid inlet hole. The multi-chamber design ensures that any
leaked e-liquid enters the second chamber without directly contacting the atomization
assembly, thereby further enhancing the sealing effect. Additionally, it effectively
prevents the anxiety of dry burning when the e-liquid in the first chamber is depleted. |
Technical Field
[0001] The present application relates to the field of atomization technology, particularly to an e-liquid core separation structure, an atomization device, and atomization equipment.
Background
[0002] Atomization device is a device that generates aerosol particles by heating an aerosol-generating substrate, typically using e-liquid as the aerosol-generating substrate. Correspondingly, the interior of the atomization device is equipped with an e-liquid cup for storing the aerosol-generating substrate and an atomization assembly for heating the e-liquid.
[0003] In traditional atomization devices, there is no isolation structure between the e-liquid stored inside the e-liquid cup and the atomization assembly within the e-liquid cup. The e-liquid can continuously seep into the atomization assembly. This design structure, when subjected to vibrations due to transportation or other external factors, can easily cause the internal e-liquid to leak from the atomization assembly. Therefore, addressing this leakage issue has become one of the key improvement areas for industry designers.

Moreover, thanks to the design of the second chamber, after the e-liquid in the first chamber is used up, the second chamber still contains e-liquid for the user to continue using for a period of time without causing the core to burn, so the user does not need to constantly check whether the e-liquid in the first chamber is used up, avoiding the anxiety of the core burning when the e-liquid in the first chamber is used up.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings. It is evident that the described embodiments are part of the embodiments of this application, rather than all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of this application.

Therefore, they should not be understood as limitations on the embodiments of this application. Moreover, the terms "first," "second," and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.
[0033] In the description of the embodiments of this application, it should be noted that unless otherwise explicitly specified and defined, the terms "install," "connect," and "link" should be understood in a broad sense. For example, they can be fixed connections, replaceable connections, or integral connections. They can be mechanical connections or electrical connections, direct connections, or indirect connections through intermediate media. They can be connections between the interiors of two elements. For those skilled in the art, the specific meanings of the above terms in the embodiments of this application can be understood according to specific situations.
[0035] Please refer to FIGs. 1 to 3. An embodiment of the e-liquid core separation structure provided in this application includes: an e-liquid cup body 100, an atomization assembly 300, and an e-liquid inlet switch 200.
[0037] The e-liquid cup body 100 is provided with a first chamber 101, a second chamber 102, a first e-liquid inlet hole 105, and a second e-liquid inlet hole 106; the first chamber 101 is used for storing e-liquid and is communicated with the second chamber 102 through the first e-liquid inlet hole 105; and the first chamber 101 can be designed as a visible chamber to facilitate the user in knowing the amount of e-liquid stored in the first chamber 101.
[0038] The second chamber 102 is communicated with the atomization assembly 300 through the second e-liquid inlet hole 106; and the e-liquid inlet switch 200 is mounted in the e-liquid cup body 100 and is used to open or close the first e-liquid inlet hole 105.
[0039] By adding a second chamber 102 in the e-liquid cup body 100 and communicating it with the atomization assembly 300 through the second e-liquid inlet hole 106, the second chamber 102 is then communicated with the first chamber 101 storing e-liquid through the first e-liquid inlet hole 105. The e-liquid inlet switch 200 is used to control the opening and closing of the first e-liquid inlet hole 105 to achieve isolation or conduction of the atomization assembly 300 and the e-liquid. With this design, only the opening and closing control of the first e-liquid inlet hole 105 is needed to achieve isolation or conduction of the atomization assembly 300 and the e-liquid. Importantly, even if the first e-liquid inlet hole 105 leaks, the leaking e-liquid will enter the second chamber 102 and not directly contact the atomization assembly 300, further enhancing the sealing effect. Moreover, thanks to the design of the second chamber 102, after the e-liquid in the first chamber 101 is used up, the second chamber 102 will still have e-liquid for the user to continue using for a period without burning the core, so the user does not need to constantly pay attention to whether the e-liquid in the first chamber 101 is used up, avoiding the anxiety of burning the core when the e-liquid in the first chamber 101 is used up.
[0040] The above is the first embodiment of the e-liquid core separation structure provided by this application. Below is the second embodiment of the e-liquid core separation structure provided by this application. Please refer to FIGs. 1 to 10.
Based on the solution of the first embodiment:
[0041] Further, the atomization assembly 300 includes an atomization core 301 and an e-liquid storage cotton 302 wrapped outside the atomization core 301 (correspondingly, the second chamber 102 is communicated with the e-liquid storage cotton 302 of the atomization assembly 300 through the second e-liquid inlet hole 106). The e-liquid storage cotton 302 supplies e-liquid to the atomization core 301 and has a certain e-liquid-locking function to prevent e-liquid from leaking from the atomization core 301. More importantly, the design of the e-liquid storage cotton 302 allows for pre-wetting, meaning that a small amount of e-liquid is stored in the e-liquid storage cotton 302 before use, so when the first e-liquid inlet hole 105 is opened for use, there is no need to consider the wetting time, and the user can directly use it, effectively avoiding abnormal phenomena such as burnt taste caused by using the atomization assembly 300 without being wetted or not being wetted properly, thus improving the user experience.
[0042] Further, in terms of the design of the e-liquid cup body 100, as shown in FIGs. 2 and 3, it includes a cup body 1 and a base body 2.
[0043] The cup body 1 is provided with a suction hole 11; the base body 2 is mounted in the cup body 1 and is provided with a third chamber 103 hermetically connected with the suction hole 11 and used to mount the atomization assembly 300; one end of the third chamber 103 away from the suction hole 11 is provided with a first air inlet hole 21 communicated with outside air to ensure the atomization assembly 300 can be used normally.
[0044] Further, in terms of the formation of the first chamber 101, as shown in FIG. 2, it is enclosed by the part of the base body 2 facing the suction hole 11 and the cup body 1. As shown in FIG. 3, a first groove chamber can be provided on the outer peripheral surface of the base body 2, and the first groove chamber and the cup body 1 can be used to enclose the second chamber 102. This design allows the base body 2 and the cup body 1 to form the corresponding first chamber 101 and second chamber 102 simultaneously when they are fitted together, and also allows the first chamber 101 and the second chamber 102 to promptly open upon detachment of the base body 2, making the design more compact and maintenance more convenient.
[0045] Correspondingly, the first e-liquid inlet hole 105 and the second e-liquid inlet hole 106 can be provided on the base body 2.
[0046] Further, as shown in FIG. 4, to facilitate the sealed connection between the third chamber 103 and the suction hole 11, a suction pipe part 12 extending into the cup body 1 is provided on the suction hole 11; at the same time, an annular flange 22 is provided on the base body 2, and the annular flange 22 is hermetically connected with the suction pipe part 12 through a first atomization sealing member 31, and the third chamber 103 is provided in the annular flange 22. The overall shape of the third chamber 103 is adapted to the e-liquid storage cotton 302 to ensure the reliable installation of the e-liquid storage cotton 302 and the atomization core 301.
[0047] Further, as shown in FIGs. 2 and 4, to ensure the reliable installation of the atomization assembly 300, one end of the atomization core 301 of the atomization assembly 300 is designed to abut against the suction pipe part 12, and the other end is hermetically connected with the third chamber 103 through a second atomization sealing member 32; one end of the e-liquid storage cotton 302 is designed to contact and abut with the first atomization sealing member 31, and the other end contacts and abuts with the second atomization sealing member 32. It can be understood that the position of the e-liquid storage cotton 302 is limited by the first atomization sealing member 31, the second atomization sealing member 32, the atomization core 301, and the inner peripheral surface of the third chamber 103; the position of the atomization core 301 is limited by the suction pipe part 12 and the bottom surface of the third chamber 103, and the atomization core 301 is hermetically connected with the suction pipe part 12 through the first atomization sealing member 31 and with the bottom surface of the third chamber 103 through the second atomization sealing member 32. The first atomization sealing member 31 is used to prevent e-liquid from leaking from the top of the atomization core 301 in the first chamber 101. The second atomization sealing member 32 is used to prevent e-liquid from leaking from the bottom of the atomization core 301 in the e-liquid storage cotton 302.
[0048] Further, as shown in FIG. 5, to achieve a better sealing connection effect, the first atomization sealing member 31 is designed to be sleeved between the annular flange 22 and the suction pipe part 12, and a first step part in contact and abutted with the annular flange 22 is provided on the outer peripheral surface of the first atomization sealing member 31; and a second step part in contact and abutted with the suction pipe part 12 is provided on the inner peripheral surface of the first atomization sealing member 31 to achieve a good sealing effect.
[0049] The second atomization sealing member 32 is sleeved on one end of the atomization core 301 away from the suction pipe part 12, and encloses the inner and outer edges of the end of the atomization core 301 to achieve a good sealing effect.
[0050] Further, to facilitate the operation of the e-liquid inlet switch 200, the e-liquid inlet switch 200 is designed to switch between an e-liquid blocking state of closing the first e-liquid inlet hole 105 and an e-liquid guiding state of opening the first e-liquid inlet hole 105 through pushing and pulling movement, that is, the e-liquid inlet switch 200 is designed as a push-pull switch.
[0051] Further, as shown in FIGs. 6 to 8, taking the push-pull design as an example, the e-liquid inlet switch 200 includes a push-pull rod 41.
[0052] The e-liquid cup body 100 is further provided with a plug hole 23 communicated with the second chamber 102 and outside air, and corresponding to the first e-liquid inlet hole 105, the push-pull rod 41 is movably provided in the first e-liquid inlet hole 105 and the plug hole 23. The design of the plug hole 23 can cooperate with the push-pull rod 41 to make the push-pull rod 41 move stably, and it also facilitates the connection of external structures with the push-pull rod 41 through the plug hole 23 to drive the push-pull rod 41 to move, or facilitates the push-pull rod 41 to extend out of the e-liquid cup body 100 for the convenience of operation.
[0053] A first switch sealing member 42 configured to hermetically contact the inner wall surface of the first e-liquid inlet hole 105 is provided on the outer peripheral surface of the push-pull rod 41 to seal the first e-liquid inlet hole 105; a second switch sealing member 43 configured to hermetically contact the inner wall surface of the plug hole 23 is provided on the outer peripheral surface of the push-pull rod 41 to seal the plug hole 23. The first switch sealing member 42 is designed as a sealing ring structure, and a first mounting groove 414 for embedding the first switch sealing member 42 is provided on the outer peripheral surface of the push-pull rod 41; similarly, the second switch sealing member 43 is designed as a sealing ring structure, and a second mounting groove 415 for embedding the second switch sealing member 43 is provided on the outer peripheral surface of the push-pull rod 41.
[0054] Further, as shown in FIG. 7, a stop convex ear in contact and abutted with the outer edge of the first e-liquid inlet hole 105 is provided on one end of the push-pull rod 41 extending into the first chamber 101 to prevent accidental operation from completely pulling out the push-pull rod 41.
[0055] Further, when the push-pull rod 41 is in a state of sealing the first e-liquid inlet hole 105, the other end of the push-pull rod 41 extends out of the plug hole 23, facilitating the action of external structures on this exposed part to push the push-pull rod 41.
[0056] Further, as shown in FIG. 9, the push-pull rod 41 is designed to include a first rod segment 411, a second rod segment 412, and a third rod segment 413.
[0057] The first rod segment 411 is of a cross-sectional shape matching the shape of the first e-liquid inlet hole 105, the third rod segment 413 is of a cross-sectional shape matching the shape of the plug hole 23, and the second rod segment 412 is integrally connected between the first rod segment 411 and the third rod segment 413.
[0058] Correspondingly, the first switch sealing member 42 is sleeved on the outer peripheral surface of the first rod segment 411, and the second switch sealing member 43 is sleeved on the outer peripheral surface of the third rod segment 413 to achieve the cooperation between the push-pull rod 41, the plug hole 23, and the first e-liquid inlet hole 105.
[0059] In this design, the cross-sectional area of the first rod segment 411 is greater than the cross-sectional area of the second rod segment 412, ensuring a larger e-liquid guiding gap is formed between the second rod segment 412 and the first e-liquid inlet hole 105 for e-liquid to pass through.
[0060] Further, as shown in FIGs. 7, 8, and 10, since there is no external air supplement inside the first chamber 101, the negative pressure inside the first chamber 101 will to some extent hinder the e-liquid from flowing into the second chamber 102, resulting in the e-liquid conduction efficiency still needing improvement. To solve this problem, in this application, when the push-pull rod 41 is in the e-liquid guiding state, the rod segment in the first e-liquid inlet hole 105 of the push-pull rod 41 is designed to divide the first e-liquid inlet hole 105 into a first e-liquid guiding channel 44 and a second e-liquid guiding channel 45. That is, the second rod segment 412 can divide the first e-liquid inlet hole 105 into the first e-liquid guiding channel 44 and the second e-liquid guiding channel 45 as shown in FIG. 10.
[0061] A non-closed side enclosure 24 is convexly provided on the outer edge of the first e-liquid inlet hole 105 facing the first chamber 101, and the inner wall surface of the non-closed side enclosure 24 is flush with the inner wall surface of the first e-liquid inlet hole 105, so as to extend the first e-liquid guiding channel 44 so that a height difference is formed between the first e-liquid guiding channel 44 and the second e-liquid guiding channel 45. This non-closed side enclosure 24 structure is a circumferentially non-closed side enclosure structure. With this design, since there is a height difference between the first e-liquid guiding channel 44 and the second e-liquid guiding channel 45, the e-liquid pressure at the entrance of the lower second e-liquid guiding channel 45 is greater than the e-liquid pressure at the entrance of the higher first e-liquid guiding channel 44, the e-liquid will flow from the lower second e-liquid guiding channel 45 into the second chamber 102, and the gas in the second chamber 102 will flow from the higher first e-liquid guiding channel 44 into the first chamber 101, thereby ensuring the pressure balance inside the first chamber 101, achieving smooth e-liquid flow, and improving e-liquid conduction efficiency. To make the separated first e-liquid guiding channel 44 and second e-liquid guiding channel 45 relatively larger, the first e-liquid inlet hole 105 can be designed as an oval hole.
[0062] Additionally, when the e-liquid inlet switch 200 is in the e-liquid blocking state, the side of the third rod segment 413 facing the first e-liquid inlet hole 105 is not lower than the bottom surface of the second chamber 102, this design can prevent e-liquid from contacting the plug hole 23, providing better sealing.
[0063] Further, the e-liquid cup body 100 is further provided with a fourth chamber 104 and a second air inlet hole 25. The fourth chamber 104 is communicated with the third chamber 103 through the first air inlet hole 21, and the fourth chamber 104 is communicated with outside air through the second air inlet hole 25. As shown in FIGs. 2 and 3, the formation of the fourth chamber 104 can also be achieved by providing a corresponding groove chamber on the outer peripheral surface of the base body 2 and using the cooperation between the groove chamber and the cup body 1 to form the fourth chamber 104. With this design, compared to the first air inlet hole 21 directly connecting to outside air, the additionally provided fourth chamber 104 can be used to fill with filtering material to filter the inhaled air, further enhancing the user experience. The filtering material can be existing materials for air filtration, which will not be elaborated here.
[0064] Further, as shown in FIG. 3, the second air inlet hole 25 is provided at one end of the fourth chamber 104 and is higher than the bottom surface of the fourth chamber 104, this design can block the e-liquid that seeps into the fourth chamber 104 to prevent it from being discharged from the second air inlet hole 25.
[0065] Further, as shown in FIGs. 4 and 6, the e-liquid cup body 100 is further provided with an e-liquid injection channel 26 communicated with the first chamber 101 and outside air to facilitate e-liquid injection, and a plug 5 is provided in the e-liquid injection channel 26 to provide a sealing function after e-liquid injection is completed.
[0066] As shown in FIG. 11, this application also discloses an atomization device, including an electrode assembly 400 and the e-liquid core separation structure of the first or second embodiment mentioned above; the electrode assembly 400 is mounted in the e-liquid cup body 100 of the e-liquid core separation structure and is electrically connected to the atomization assembly 300 of the e-liquid core separation structure. Specifically, the electrode assembly 400 is mounted at the bottom of the base body 2.
[0067] As shown in FIG. 12, this application also discloses an atomization equipment, including a rod body 500 and the above-mentioned atomization device; the atomization device can be detachably inserted on the rod body 500, and the insertion method of the atomization device on the rod body 500 can refer to existing insertion fit structures for design or directly use them, such as completing the insertion in place by snap fit.
[0068] Further, to achieve the linkage between the atomization device and the rod body 500, taking as an example the design of the e-liquid inlet switch 200 of the atomization device that can switch between the e-liquid blocking state of closing the first e-liquid inlet hole 105 and the e-liquid guiding state of opening the first e-liquid inlet hole 105 through pushing and pulling movement.
[0069] Correspondingly, a drive structure 6 is provided on the rod body 500, and the drive structure 6 is used to drive the e-liquid inlet switch 200 to the e-liquid guiding state during the process of inserting the atomization device on the rod body 500.
[0070] Further, as shown in FIGs. 11 and 14, the drive structure 6 can be designed to include a top pushing part 61 provided on the rod body 500.
[0071] During the process of inserting the atomization device on the rod body 500, the top pushing part 61 contacts the e-liquid inlet switch 200 and forms a top pushing on the e-liquid inlet switch 200 so that when the atomization device is inserted in place, the e-liquid inlet switch 200 moves to the e-liquid guiding state. Taking the example where one end of the e-liquid inlet switch 200 extends out of the plug hole 23 when in the e-liquid blocking state, the top pushing part 61 can directly push the part extending out of the plug hole 23 without needing to enter the plug hole 23; of course, if one end of the e-liquid inlet switch 200 does not extend out of the plug hole 23 when in the e-liquid blocking state, the top pushing part 61 needs to be designed to extend into the plug hole 23 to push the e-liquid inlet switch 200.
[0072] Further, as shown in FIG. 13, an elastic member 600 is connected between the e-liquid cup body 100 and the e-liquid inlet switch 200 of the atomization device, and the elastic member 600 provides an elastic force to drive the e-liquid inlet switch 200 to switch to the e-liquid blocking state during the process of the atomization device leaving the rod body 500. The elastic member 600 can be a spring, specifically, when the e-liquid inlet switch 200 is designed to be in the e-liquid blocking state, one end does not extend out of the plug hole 23, and an elastic member 600 is sleeved on the extending part, making one end of the elastic member 600 contact and abut with the outer edge of the plug hole 23 or the bottom of the base body 2, and the other end contacts and abuts with the stop part on the extending part to provide elastic force; the elastic member 600 can be a compression spring. With this design, when the atomization device is removed, the elastic force of the elastic member 600 can be used to pull the e-liquid inlet switch 200 to reset to the e-liquid blocking state, without the user needing to pull the e-liquid inlet switch 200, making it more convenient to use and further enhancing the user experience.
[0073] Further, for the atomization device after removal, the e-liquid inlet switch 200 can also be manually operated to move to the e-liquid blocking state. To facilitate manual operation, the e-liquid inlet switch 200 is designed to have at least a part extending out of the e-liquid cup body 100 when in the e-liquid guiding state, forming an operation part for pulling the e-liquid inlet switch 200 to move to the e-liquid blocking state.
[0074] Further, as shown in FIG. 14, besides the automatic return operation mode of the elastic member 600 mentioned above, a first buckle part 201 can also be provided on the e-liquid inlet switch 200.
[0075] The drive structure 6 includes a second buckle part 62 provided on the rod body 500, and the second buckle part 62 can be provided on the top pushing part 61.
[0076] The second buckle part 62 is used to engage with the first buckle part 201 when the atomization device is inserted in place, and to pull the e-liquid inlet switch 200 to move to the e-liquid blocking state during the process of the atomization device leaving the rod body 500. The first buckle part 201 or the second buckle part 62 is an elastic buckle part, so that the engaged first buckle part 201 and second buckle part 62 can be separated when subjected to a preset external force. After reaching the e-liquid blocking state, continuing to apply an outward force on the atomization device can separate the first buckle part 201 and the second buckle part 62. The second buckle part 62 cooperates with the top pushing part 61, making the drive structure 6 capable of both pushing and pulling the e-liquid inlet switch 200.
