Therefore, the specification and the drawings are only for clearly describing a certain embodiment, and do not mean to be the necessary composition and / or sequence.

[0040] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connections (couplings).

[0041] Please refer to Figures 1 to 8, the electronic atomization device 1 is an appliance for heating and atomizing a matrix to form an aerosol. The electronic atomization device 1 includes a housing assembly 10, a power supply assembly 50 and an atomizer. The housing assembly 10 provides an installation space for the atomizer and the power supply assembly 50. The power supply device is used to supply power to the atomizer. The power supply assembly 50 includes a battery 51 and a circuit board 52 that are electrically connected to each other. The circuit board 52 can control the start, stop or change the working power of the controller according to the user's operation to adapt to different types of atomization matrices or the aerosol volume usage requirements of different users. After being powered on, the atomizer heats the atomization matrix inside it. The atomizer includes a liquid storage cavity 111, an atomization cavity 411 and an atomization core assembly 40. The atomization core assembly 40 is arranged in the atomization cavity 411. There is a liquid path channel between the atomization cavity 411 and the liquid storage cavity 111. When the user sucks, the atomization matrix in the liquid storage cavity 111 can enter the atomization cavity 411 and be heated by the atomization core assembly 40 to form an aerosol.

[0042] It should be noted that the aerosol mentioned in the terms refers to a dispersion of solid particles or liquid particles in a gas. The "aerosol" used in this article is usually used to refer to a substance that has been vaporized, atomized, in the form of a spray or jet, or otherwise transformed from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0043] The atomization matrix is any suitable compound or mixture of compounds that facilitates aerosol formation during use. The atomization matrix includes, but is not limited to: polyols such as triethylene glycol, 1,3-butanediol and glycerol; esters of polyols such as glycerol mono-, di- or triacetate; and aliphatic esters of mono-, di- or polycarboxylic acids such as dimethyl dodecanedioate and dimethyl tetradecanedioate. It may also include nicotine. Or it may include glycerol (also known as glycerin) with a boiling point higher than nicotine. It may also include propylene glycol or plant-based materials. In order to improve the taste, atomization effect, etc. of e-cigarette oil, some other ingredients will also be added, such as edible non-ionic additives such as polyethylene glycol 200, polyethylene glycol 400, sorbitan fatty acid esters, and various flavors and fragrances. Flavors and fragrances include sweeteners, cooling agents, etc.

[0044] The housing assembly 10 can be understood as an aggregate of multiple combined components. Corresponding spaces and assembly structures can be formed inside the housing assembly 10 to facilitate the installation of the atomizer and the power supply assembly 50. The setting of the housing assembly 10 also facilitates the overall carrying or movement of the atomizer and the power supply assembly 50.

[0045] Please refer to Figure 2, a seal 20 and a mounting bracket 30 are provided inside the housing assembly 10, and the seal 20 and the mounting bracket 30 are arranged in sequence along the first direction Y inside the housing assembly 10, and divide the inside of the housing assembly 10 into an atomization space 11, a collection space 12 and an electrical installation space 13 arranged in sequence along the first direction Y; wherein, an atomization core assembly 40 is provided in the atomization space 11; the collection space 12 is used to collect the liquid from the atomization core assembly 40 (including atomization matrix or aerosol condensate); a power supply assembly 50 is provided in the electrical installation space 13, and the circuit board 52 in the power supply assembly 50 is fixed on the mounting bracket 30, and the battery 51 is clamped in the space between the mounting bracket 30 and the housing assembly 10.

[0046] The circuit board 52 being fixed on the mounting bracket 30 includes the circuit board 52 being directly fixedly connected to the mounting bracket 30. For example, corresponding buckle structures are provided on the mounting bracket 30 and the circuit board 52, and the mounting bracket 30 and the circuit board 52 are buckled and connected. It may also include welding and fixing the circuit board 52 on the mounting bracket 30, and may also include fixing the circuit board 52 on the circuit board 52 by screws, bolts or pins, etc.

[0047] Due to the settings of the seal 20 and the mounting bracket 30, not only an installation basis is provided for the atomizer and the power supply assembly 50, enabling the atomizer and the power supply assembly 50 to be integrally integrated inside the housing assembly 10, but also the two can be isolated from each other, reducing the size and weight of the electronic atomization device 1, and thus significantly improving the hand feeling when the user holds it, bringing a more comfortable use experience to the user. Since the atomization core assembly 40 and the power supply assembly 50 are assembled and separated by the seal 20 and the mounting bracket 30, the corresponding assembly structure and sealing structure inside the housing assembly 10 are simplified, thereby reducing the production cost of the electronic atomization device 1 and the user's usage cost, reducing the assembly links of the electronic atomization device 1 and reducing the assembly difficulty, which is beneficial to the market promotion of the electronic atomization device 1. Through the setting of the collection space 12, the liquid from the atomization chamber 411 can be collected, thereby preventing the liquid from flowing to the power supply assembly 50, avoiding the atomization matrix from corroding or damaging the power supply assembly 50, and effectively improving the service life of the power supply assembly 50.

[0048] Please refer to Figure 3, in some embodiments, the housing assembly 10 includes a housing 14. A partition 141 is disposed inside the housing 14. The partition 141 abuts against one side of the seal 20 to form a liquid storage chamber 111 and an air inlet chamber 112 that are isolated from each other on both sides of the partition 141. The liquid storage chamber 111 is used to store the atomization matrix; an atomization chamber 411 is provided in the liquid storage chamber 111, and the atomization core assembly 40 is disposed in the atomization chamber 411; the air inlet chamber 112 is communicated with the atomization chamber 411 through a collection space 12. The air inlet chamber 112 is communicated with the external environment, and is used to guide the external air to enter the atomization chamber 411 through the collection space 12, and carry the aerosol generated in the atomization chamber 411 to the outside of the electronic atomization device 1. The housing 14 and the partition 141 are integrally formed, thereby reducing the setting of the sealing structure in the housing assembly 10, saving the assembly procedure. At the same time, by directly forming the liquid storage chamber 111 and the air inlet chamber 112 through the cavity wall of the housing 14, the overall volume of the housing assembly 10 can be reduced, the volume inside the housing assembly 10 can be increased, the space utilization rate of the entire electronic atomization device 1 can be effectively improved, and the overall volume and weight of the electronic atomization device 1 can be further reduced. Of course, in other embodiments, the housing 14 and the partition 141 can also be separately designed to facilitate the disassembly and assembly of other components shown in the electronic atomization device 1.

[0049] Please refer to Figure 3 and Figure 4 , in some embodiments, the seal 20 includes a first seal portion 21 and a second seal portion 22 that are continuously arranged perpendicular to the second direction X. The extension length of the first seal portion 21 in the first direction Y is greater than that of the second seal portion 22. The partition 141 abuts against the second seal portion 22 in the first direction Y, so that the partition 141, the first seal portion 21 and the housing 14 form the liquid storage chamber 111, and the partition 141, the second seal portion 22 and the housing 14 form the air inlet chamber 112.

[0050] The first direction Y and the second direction X are perpendicular to each other. The first direction Y is the extending direction of the atomization chamber 411, and is also the flowing direction of the aerosol. At the same time, it is the longitudinal direction when the electronic atomization device 1 is normally placed during user use. The second direction X is the transverse direction when the electronic atomization device 1 is normally placed. The liquid storage chamber 111 and the air inlet chamber 112 are placed horizontally, and the liquid storage chamber 111, the collection space 12 and the electrical installation space 13 are placed longitudinally. This design can achieve the full utilization of the space inside the housing assembly 10.

[0051] Further, since there is a height difference between the first sealing portion 21 and the second sealing portion 22 in the first direction Y, in order to save space and improve the sealing performance, the partition 141 abuts against the first sealing portion 21 in the second direction X, that is, one side of the partition 141 in the second direction X abuts against the first sealing portion 21, one end of the partition 141 in the first direction Y abuts against the inside of the housing 14, and the other end abuts against the side of the second sealing portion 22 facing the intake cavity 112, so as to substantially form an L-shaped sealing line between the first sealing portion 21, the second sealing portion 22 and the partition 141, improving the isolation and sealing effect between the intake cavity 112 and the liquid storage cavity 111, and avoiding the influence on the atomization effect caused by the leakage of the intake cavity 112 to the liquid storage cavity 111, or the leakage of the liquid storage cavity 111 to the intake cavity 112 and then directly leaking to the outside of the electronic atomization device 1 through the intake cavity 112. A sealing line is formed between the first sealing portion 21 and the second sealing portion 22 and the housing 14, so that the atomization space 11 and the collection space 12 are completely sealed and isolated except for the opening at the lower end of the atomization cavity 411 and the communication port between the intake cavity 112 and the collection space 12.

[0052] Please continue to refer to Figure 3 、 Figure 4 and Figure 5 , in some embodiments, a first air inlet 142 is provided on the housing 14, and the intake cavity 112 communicates with the external environment through the first air inlet 142; a second air inlet 221 is provided on the second sealing portion 22, and the intake cavity 112 communicates with the collection space 12 through the second air inlet 221; an installation cavity 211 penetrating through itself in the first direction Y is formed on the first sealing portion 21, and at least part of the atomization core assembly 40 is installed in the installation cavity 211. When the user sucks, the external air enters the intake cavity 112 through the first air inlet 142, and then enters the atomization cavity 411 through the second air inlet 221 and then through the collection space 12. The setting of the installation cavity 211 not only provides an installation basis for the atomization core assembly 40, but also can realize the sealing between the atomization core assembly 40 and the liquid storage cavity 111, and the opening of the installation cavity 211 facing the collection space 12 can also communicate the collection space 12 and the atomization cavity 411.

[0053] Please continue to refer to Figure 5 , a liquid injection port 143 and a liquid injection plug 144 are provided on the housing 14, the liquid injection port 143 communicates with the liquid storage cavity 111, and the liquid injection plug 144 is used to block or open the liquid injection port 143. Through the setting of the liquid injection port 143, repeated liquid injection into the liquid storage cavity 111 can be realized. On the one hand, the service life of the atomizer can be extended by supplementing the atomization matrix, avoiding equipment waste caused by scrapping due to the depletion of the atomization matrix when the atomization core assembly 40 and the power supply assembly 50 have not reached their service lives. On the other hand, the situation of loss of the atomizer or the power supply assembly 50 or liquid leakage of the atomizer caused by repeated disassembly of the atomizer can be avoided.

[0054] Through the setting of the liquid injection port 143, additives can also be supplemented into the liquid storage cavity 111 to adjust the taste of the atomization matrix (such as sweetness, cool feeling, etc.), bringing users a flexible and rich usage experience.

[0055] The atomization core assembly 40 includes an atomization cover 41 and an atomization core 42. The atomization cover 41 is arranged in the liquid storage cavity 111 and is respectively connected to the outer shell 14 and the seal 20 at both ends; an atomization cavity 411 is arranged in the atomization cover 41, and the atomization core 42 is arranged in the atomization cavity 411; a liquid inlet 412 is arranged on the atomization cover 41, and the liquid inlet 412 communicates with the liquid storage cavity 111 and the atomization cavity 411. When the user sucks, the atomization matrix in the liquid storage cavity 111 enters the atomization cavity 411 through the liquid inlet 412 and is heated by the atomization core 42. The atomization core 42 includes a liquid storage member (such as a liquid storage cotton or a porous ceramic body) and a heating element arranged on the inner surface or the outer surface of the liquid storage member. The heating element is in a mesh structure, a spiral structure or a hollow cylindrical structure, and the heating element is electrically connected to the power supply assembly 50. After being powered on, the heating element heats the atomization matrix. Different from the traditional solution of forming a liquid storage cavity 111 and an atomization channel in the housing assembly 10 and arranging the atomization core assembly 40 in the atomization channel, the present application directly uses the atomization cover 41 to assemble the atomization core 42, isolate it from the liquid storage cavity 111, and form the atomization cavity 411, which can further effectively reduce the structure of the housing assembly 10 and maximize the application of the volume in the housing assembly 10.

[0056] Please continue to refer to Figure 5 , the housing assembly 10 further includes a mouthpiece 15, a bottom cover 16 and a mounting tube 17. The mouthpiece 15 and the bottom cover 16 are oppositely arranged at both ends of the outer shell 14 in the first direction Y. The mouthpiece 15 communicates with the atomization cavity 411 and also communicates with the outside. The user completes the sucking action through the mouthpiece 15; the mounting tube 17 is installed in the electrical installation space 13. The mounting tube 17 has an accommodating cavity for assembling the power supply assembly 50. The setting of the mounting tube 17 provides an assembling and fixing basis for the power supply assembly 50.

[0057] In some embodiments, the housing 14 is made of a transparent material so as to view the operation of the various components within the electronic atomization device 1, particularly the operation of the atomizer and the liquid level of the liquid storage chamber 111, so as to replenish the atomization matrix in a timely manner. The mounting tube 17 includes a metal tube. Taking advantage of the certain strength and good ductility of the metal material, using the metal tube as the assembly basis for the power supply component 50 can reduce the thickness of the mounting tube 17. With the very small-volume mounting tube 17, the assembly and protection of the power supply component 50 can be achieved. When the metal tube is assembled with the housing 14, by the abutment of the bottom cover 16 and the bracket assembly on both ends of the metal tube, and through the interference fit between the metal tube and the housing 14, the metal tube is fixed within the housing 14. No additional assembly structure needs to be provided, and the metal tube is not easily deformed, which can further simplify the internal structure of the housing assembly 10 and simplify the structure of its production mold. Exemplarily, the metal tube can be a stainless steel thin-walled tube, a steel-plastic composite tube, etc.

[0058] In order to enhance the design sense of the electronic atomization device 1, the metal tube has a decorative structure, which includes a preset pattern or color. Through the combination of the pattern and color, the power supply component 50 can be blocked to enhance the ornamental value of the electronic atomization device 1 and bring a good visual effect to the user. The decorative structure can be formed by engraving and printing on the outer surface of the metal tube or by pasting a sticker.

[0059] Please continue to refer to Figure 5 , an induction chamber 31 and an induction channel 32 communicating with the induction chamber 31 are provided on the mounting bracket 30. An air flow sensor 53 is provided in the induction chamber 31, and the air flow sensor 53 is electrically connected to the power supply component 50; the induction channel 32 communicates with the collection space 12, and the air flow sensor 53 is electrically connected to the circuit board 52. Through the setting of the induction channel 32 and the air flow sensor 53, when the user sucks, the outside air enters the collection space 12 through the first air inlet hole, the air inlet chamber 112, and the second air inlet 221, and enters the atomization chamber 411 from the collection space 12. When the air flows through the collection space 12, a pressure difference (Bernoulli effect) is formed on both sides of the induction channel 32. This pressure change is acquired by the air flow sensor 53 and transmitted to the circuit board 52, and the circuit board 52 triggers the atomization core assembly 40 to work, thus realizing the self-start of the electronic atomization device 1 and improving the start-up efficiency of the electronic atomization device 1.

[0060] In some embodiments, an air vent portion 33 is provided on the side of the mounting bracket 30 facing the seal 20. The outlet end of the air vent portion 33 communicates with the induction channel 32, and the inlet end of the air vent portion 33 is disposed in the collection space 12 and is spaced apart from the seal 20. The intake section of the air vent portion 33 is disposed in the collection space 12, that is, the inlet end is higher than the bottom wall of the collection space 12. Since the collection space 12 is used to collect the atomized matrix or the aerosol condensate, the atomized matrix or the aerosol condensate has a certain viscosity and generally flows along the wall of the collection space 12, and its volume is small. Based on this, setting the inlet end higher than the bottom wall of the collection space 12 can prevent the atomized matrix or the aerosol condensate from entering the induction cavity 31 through the inlet end and affecting the service life and sensitivity of the airflow sensor 53. The spaced arrangement of the seal 20 and the inlet end allows air to first enter the collection space 12 and then flow through the inlet end of the air vent portion 33, effectively ensuring the sensitivity of the airflow detection of the airflow sensor 53. The airflow sensor 53 includes a differential pressure sensor or a MEMS airflow sensor 53. In some specific embodiments, the airflow sensor 53 includes an induction body and a seal sleeve. One side of the induction body is disposed on the circuit board 52, and the other side is covered by the seal sleeve, and the seal sleeve is provided with a through hole communicating the induction surface of the induction body with the induction cavity 31. Preferably, the air vent portion 33 extends along the first direction Y.

[0061] Further, in some embodiments, the orthographic projections of the air vent portion 33 and the atomization chamber 411 along the first direction Y are staggeredly arranged, avoiding the existence of relative portions of the air vent portion 33 and the atomization chamber 411 in the first direction Y, and avoiding the atomized matrix or the aerosol condensate from directly falling into the induction channel 32 and the induction cavity 31 under the action of gravity, effectively preventing the atomized matrix or the aerosol condensate from flowing to the airflow sensor 53. The orthographic projections of the air vent portion 33 and the intake cavity 112 along the first direction Y can also be staggeredly arranged to avoid affecting the sensitivity and accuracy of the airflow sensor 53 due to the second air inlet 221 directly facing the air vent portion 33.

[0062] Please continue to refer to Figure 5 , in some specific embodiments, the mounting bracket 30 includes a first frame body 34 extending along the first direction Y and a second frame body 35 extending along the second direction X. The second frame body 35 and the seal 20 form the collection space 12, and the air vent portion 33 is disposed on the side of the second frame body 35 facing the atomization space 11. The circuit board 52 is fixed to the first frame body 34, and the installation cavity 211 and the installation channel are formed at the connection of the first frame body 34 and the second frame body 35. The housing 14, the installation pipe 17, the first frame body 34 and the battery 51 are arranged in sequence from inside to outside to achieve stable connection of the battery 51. The first frame body 34 is an arc-shaped structure and partially covers the outside of the battery 51.

[0063] Since the airflow sensor 53 can immediately start the atomization core assembly 40 to work when the user sucks, if there is no atomization matrix in the liquid storage cavity 111 of the electronic atomization device 1, the atomization core assembly 40 is likely to be damaged due to dry burning or produce a burnt smell after starting, which will affect the subsequent aerosol taste. To solve this problem, the power supply assembly 50 further includes an activation mechanism 60. The activation mechanism 60 is used to trigger the circuit board 52 to control the electronic atomization device 1 to switch from the unactivated state to the activated state. In the unactivated state, no matter how the user sucks, at this time, the airflow sensor 53, the atomization core assembly 40 and the circuit board 52 are in a power-off state, and the start of the atomization core assembly 40 cannot be realized. In the activated state, the airflow sensor 53, the atomization core assembly 40 and the circuit board 52 are in a powered-on state. After the user sucks, the start of the atomization core assembly 40 can be realized by the cooperation of the airflow sensor 53 and the circuit board 52.

[0064] Please refer to Figure 6 and Figure 7 , in some embodiments, a first electronic component 521 and a second electronic component 522 are provided on the circuit board 52. The activation mechanism 60 includes an elastic connecting member 61 and a triggering member 62. The elastic connecting member 61 is used to electrically connect the first electronic component 521 and the second electronic component 522, so that the electronic atomization device 1 is in the activated state; the triggering member 62 is movably disposed between the second electronic component 522 and the elastic connecting member 61, and is used to block or conduct the electrical connection between the first electronic component 521 and the second electronic component 522, so that the electronic atomization device 1 switches from the unactivated state to the activated state. Specifically, the triggering member 62 is an insulating structure and can be disposed on the second electronic component 522 to block the conduction between the first electronic component 521 and the second electronic component 522, so that the airflow sensor 53, the atomization core assembly 40 and the circuit board 52 are in a power-off state. After moving away from the second electronic component 522, the elastic connecting member 61 connects the first electronic component 521 and the second electronic component 522, so that the airflow sensor 53, the atomization core assembly 40 and the circuit board 52 are in a powered-on state. The circuit board 52 is disposed between the housing 14 and the mounting tube 17 along the first direction Y, and the first electronic component 521 and the second electronic component 522 are spaced along the first direction Y, so that the elastic connecting member 61 is compressed and disposed between the housing 14 and the triggering member 62. After the triggering member 62 moves away from the second electronic component 522, under the action of the elastic restoring force, the elastic connecting member 61 connects the first electronic component 521 and the second electronic component 522. The triggering member 62 is an insulating strip or an insulating sheet. In order to save space for the electronic device, the triggering member 62 is an insulating sheet. Exemplarily, the triggering member 62 is a PET insulating sheet.

[0065] Since the trigger member 62 is movably disposed on the second electronic component 522, there is a risk that the trigger member 62 may be detached from the second electronic component 522 due to shaking or vibration during the carrying and transportation of the electronic atomization device 1. Please continue to refer to Figure 6 and Figure 7 , a pressing block 63 is further provided between the second electronic component 522 and the housing 14. The trigger member 62 is tightly pressed on the second electronic component 522 through the pressing block 63. The pressing block 63 is an elastic structure, which can buffer the acting force applied to the trigger member 62 by shaking and vibration, can protect the trigger member 62, and can effectively resist external interferences such as shaking and vibration, and at the same time counteract the action of gravity on the trigger member 62 to ensure that the trigger member 62 will not be far away from the second electronic component 522 due to the above factors.

[0066] In order to improve the power endurance of the power supply assembly 50, the battery 51 is a large-capacity battery 51 with a capacity designed to be 800 mah to meet the use requirements of the atomization core assembly 40 for the user to achieve high-power use for a long time.

[0067] In some embodiments, the power supply assembly 50 further includes a charging interface 54. The charging interface 54 is electrically connected to the battery 51 through the circuit board 52. The charging interface 54 is used to connect an external power source to charge the battery 51, and can recharge the battery 51, thereby further improving the power endurance of the power supply assembly 50. The charging interface 54 can be a USB interface. In some specific embodiments, the charging interface 54 can also function as an output interface for the working condition of the electronic atomization device 1.

[0068] Please continue to refer to Figure 7, the power supply assembly 50 further includes an indicator light 55, a cover plate 56, and a light guide column 57. The indicator light 55 is electrically connected to the control board. The cover plate 56 is disposed between the control board and the housing assembly 10. The light guide column 57 is used to guide the light of the indicator light 55 to the outside of the housing assembly 10. A first mounting hole 561 is provided on the cover plate 56, and a second mounting hole 18 is provided on the housing assembly 10. One end of the light guide column 57 is electrically connected to the indicator light 55, and the other end sequentially passes through the first mounting hole 561 and the second mounting hole 18 and is exposed outside the housing assembly 10. Specifically, both the cover plate 56 and the circuit board 52 extend along the first direction Y, and the cover plate 56 is disposed between the inner wall of the outer shell 14 and the circuit board 52. The first mounting hole 561 penetrates the cover plate 56 along the second direction X; the second mounting hole 18 penetrates the outer shell 14 along the second direction X. The light guide column 57 and the indicator light 55 can play an indicating role when the user charges the electronic atomization device 1. Of course, in some other embodiments, the light guide column 57 can be provided with various colors, such as green, red, and yellow, which can not only display the charging state but also display the working condition of the electronic atomization core assembly 40. For example, the working conditions of high power, medium power, or low power are displayed in three different colors. The setting of the cover plate 56 facilitates the installation and fixation of the indicator light 55 and the light guide column 57. The cover plate 56 also provides an installation base for the above-mentioned pressing block 63, and the pressing block 63 can be clamped and fixed between the circuit board 52 and the cover plate 56.

[0069] Please refer to Figure 8 , in some embodiments, a first electrode hole 341 is provided on the mounting bracket 30, a second electrode hole 212 is provided on the seal 20, and the power supply assembly 50 includes a power supply electrode 58. One end of the power supply electrode 58 is electrically connected to the battery 51, and the other end sequentially passes through the first electrode hole 341 and the second electrode hole 212 and is electrically connected to the atomization core assembly 40. The power supply electrode 58 is in interference fit with the first mounting hole 561 and the second mounting hole 18. The seal 20 can be made of silicone material, so that a sealed setting is provided between the power supply electrode 58 and the second electrode hole 212, and liquid leakage from the second electrode hole 212 can be avoided. Of course, a sealing structure, such as a sealing ring or a sealing block, can also be provided between the power supply electrode 58 and the first electrode hole 341 and the second electrode hole 212 to improve the sealing effect here. Specifically, the first electrode hole 341 penetrates the first frame body 34 along the first direction Y. The second electrode hole 212 is provided on the first seal 20. After the power supply electrode 58 is disposed in the second electrode hole 212 on the first seal 20, the connecting wire of the atomization core 42 is guided into the second electrode hole 212 to be electrically connected to the power supply electrode 58.

[0070] In some embodiments, the electronic atomization device 1 includes a first limiting member 70 and a second limiting member 80. The first limiting member 70 is disposed between the side surface of the battery 51 and the mounting tube 17, and the second limiting member 80 is disposed on the side of the battery 51 facing the atomization space 11. By providing the first limiting member 70 and the second limiting member 80, the battery 51 can be stably disposed in the mounting tube 17, preventing the battery 51 from shifting during carrying or transportation. Of course, the first limiting member 70 and the second limiting member 80 can also play a buffering role to protect the battery 51. Based on this, the first limiting member 70 and the second limiting member 80 can be made of porous fiber (such as foam) or a sheet or block structure made of silica gel (with elasticity). When the first limiting member 70 and the second limiting member 80 are made of porous fiber, they also have a certain adsorption effect on liquids. The first limiting member 70 can completely cover the side surface of the battery 51 or partially cover the side surface of the battery 51. The second limiting member 80 can also completely cover the end of the battery 51 or partially cover the end of the battery 51. In some specific embodiments, the second limiting member 80 is made of porous fiber and completely covers the end of the battery 51 to protect the end of the battery 51 and the power supply electrode 58 at the end in case of liquid leakage. The first limiting member 70 is made of any one of the above, and the first limiting member 70 partially covers the side surface of the battery 51 to fill the gap between the battery 51 and the mounting tube 17, and the first limiting member 70 is disposed between the exposed part of the battery 51 on the first frame body 34 and the mounting tube 17.
