DETAILED DESCRIPTION

[0028] The application will be further described in details through specific embodiments combined with the drawings. In different embodiments, similar elements are marked with similar element reference numbers. In the following embodiments, many details are described in order to make the application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different cases, or can be replaced by other elements, materials, methods. In some cases, some operations related to the application are not shown or described in the specification, in order to avoid the core part of the application being overwhelmed by too much description, and it is not necessary to describe these related operations in detail for those skilled in the art according to the description in the specification and general technical knowledge in the art.

[0029] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate way to form various embodiments. At the same time, the steps or actions in the method description can also be sequentially adjusted or adjusted in a manner that is obvious to those skilled in the art. Therefore, the order in the specification and the drawings is only for the purpose of clearly describing a certain embodiment, and does not mean that it is the necessary order, unless otherwise stated that a certain order must be followed.

[0030] The serial numbers of components in this document, such as "first", "second", etc., are only used to distinguish the described objects, and have no technical meaning. Unless otherwise specified, "connected", "coupled" in this application includes direct and indirect connections (couplings).

[0031] As shown in Figures 1 to 4 The electronic atomization device 1 provided by the application can heat and atomize liquid substrate to generate aerosol for user. The electronic atomization device 1 includes a shell 10, an atomizer module 20, a battery module 30 and a main control module 40. The shell 10 has a first end and a second end arranged opposite to each other, and an installation cavity 100 is defined in the shell 10 and extends through from the first end to the second end. The atomizer module 20 is detachably inserted into the installation cavity 100 from the first end, and can store liquid substrate and heat and atomize the liquid substrate after being powered. The battery module 30 is also detachably inserted into the installation cavity 100 from the first end and is electrically connected with the atomizer module 20, and is used for supplying power for the atomization of the atomizer module 20. The battery module 30 and the atomizer module 20 can be arranged transversely and side by side along the shell 10. The main control module 40 is inserted into the installation cavity 100 from the second end and is electrically connected with the battery module 30 and the atomizer module 20, and can control the battery module 30 to supply power to the atomizer module 20.

[0032] By arranging the shell 10, the atomizer module 20, the battery module 30 and the main control module 40 as several mutually independent and detachable parts, the electronic atomization device 1 can be conveniently disassembled and assembled. When assembling the electronic atomization device 1, the user only needs to insert the atomizer module 20, the battery module 30 and the main control module 40 into the shell 10 from the first end and the second end, respectively, to complete the assembly. The insertion manner can simplify the operation of the user and improve the user experience.

[0033] If the parts in the electronic atomization device 1 need to be recycled, the insertion manner also simplifies the disassembly operation of the electronic atomization device 1. For example, if the battery module 30 needs to be recycled, the battery module 30 can be taken out from the first end of the shell 10, and the steps are simple and easy to operate, which is convenient for the user to disassemble.

[0034] Of course, in other optional embodiments, at least one of the atomizer module 20, the battery module 30 and the main control module 40 can be fixedly arranged with the shell 10.

[0035] As shown in Figure 3 and Figure 4As shown, the housing 10 can be substantially in a flat cylindrical structure with two ends penetrating therethrough, the first end and the second end being opposite ends of the cylindrical structure along the axial direction. The cross section perpendicular to the axial direction of the housing 10 is substantially in a flat oval or track shape, so that the battery module 30 and the atomizer module 20 can be arranged in parallel to the axis of the housing 10 in the mounting cavity 100.

[0036] Of course, the housing 10 can also be provided in a cylindrical shape, a polygonal cylindrical shape, an irregular cylindrical shape, or other shapes. The line between the first end and the second end can be parallel to the axis of the housing 10 or have an included angle.

[0037] In some embodiments, the housing 10 can include a shell 11 and at least one partition structure 12. The shell 11 defines a mounting cavity 100 with two ends penetrating therethrough, and the partition structure 12 is arranged on the inner wall surface of the shell 11, i.e., on the cavity wall of the mounting cavity 100. The partition structure 12 extends from the first end to the second end, parallel to the axial direction of the housing 10. The partition structure 12 can separate part of the mounting cavity 100 into a battery receiving cavity 60 and an atomizer receiving cavity 50.

[0038] The battery receiving cavity 60 and the atomizer receiving cavity 50 both extend along the axial direction of the housing 10 and are arranged in parallel along the direction perpendicular to the axial direction of the housing 10. The atomizer receiving cavity 50 is formed with an opening towards the first end, and the atomizer module 20 can be inserted into the atomizer receiving cavity 50 from the opening. The battery receiving cavity 60 is formed with an opening towards the first end, and the battery module 30 can be inserted into the battery receiving cavity 60 from the opening.

[0039] By providing the partition structure 12, the assembly work of the electronic atomization device 1 can be further facilitated. When inserting the atomizer module 20 and the battery module 30, there is no need to consider the limiting problem of one of them being inserted into the mounting cavity 100 first, so as to facilitate the insertion of the other one.

[0040] Further, the number of partition structures 12 can be at least two, which can be divided into two groups and symmetrically arranged on the opposite side walls of the shell 11, cooperating to limit the atomizer module 20 and the battery module 30 perpendicular to the axial direction, thereby dividing the atomizer receiving cavity 50 and the battery receiving cavity 60.

[0041] Specifically, each partition structure 12 can include at least one rib, which can be longitudinally arranged and extend along the axial direction of the housing 10. There is a gap between the two partition structures 12 located on the opposite side walls of the shell 11, and the atomizer receiving cavity 50 and the battery receiving cavity 60 can be communicated through the gap between the two partition structures 12.

[0042] It should be understood that when the partition structure 12 comprises at least two ribs, the structure of a single rib can also be arranged in a non-longitudinal manner. The at least two ribs are arranged on the side wall of the shell 11 in parallel to the axial direction of the shell 11, and cooperate to achieve the division of the space.

[0043] In some other optional embodiments, the number of the partition structure 12 can also be one, which can be arranged in a plate-shaped structure and arranged transversely in the shell 11, so as to separate the atomizer accommodation cavity 50 and the battery accommodation cavity 60 from each other.

[0044] In some other optional embodiments, the partition structure 12 can also be arranged as a guide rail structure protruding from the side wall corresponding to the atomizer accommodation cavity 50 and / or the side wall corresponding to the battery accommodation cavity 60, or as a guide groove structure. Through the guide rail or guide groove, the atomizer module 20 and / or the battery module 30 are inserted in the axial direction while being limited. During the assembly of the electronic atomization device 1, the user can first insert the module corresponding to the accommodation cavity provided with the guide groove or guide rail structure therein, without the need for manual limiting, and then continue to install the remaining modules.

[0045] As shown in Figure 2 In some embodiments, the atomizer module 20 can comprise an atomization shell 21, an atomization assembly 22, and a liquid storage assembly 23. The atomization shell 21 is detachably inserted into the atomizer accommodation cavity 50 in the axial direction of the shell 11. The atomization assembly 22 and the liquid storage assembly 23 are arranged in the atomization shell 21. The liquid storage assembly 23 stores liquid substrate. The atomization assembly 22 is arranged in the liquid storage assembly 23 and electrically connected to the control module 40, and is used to atomize the liquid substrate in the liquid storage assembly 23.

[0046] Referring to Figure 3 and Figure 4 The shape of the atomization shell 21 is adapted to the shape of the cavity of the atomizer accommodation cavity 50, so that the side wall of the atomization shell 21 is in surface contact with the cavity wall of the atomizer accommodation cavity 50, and the cavity side wall plays a guiding role during insertion. Specifically, it can be arranged in various shapes such as a cylindrical shape, a polygonal cylindrical shape, an irregular cylindrical shape, a pie shape, a semicircular cylindrical shape, an elliptical cylindrical shape, etc., which are not limited here. Of course, the side wall of the atomization shell 21 can also be spaced apart from at least part of the cavity wall of the atomizer accommodation cavity 50.

[0047] In some embodiments, the atomization shell 21 can comprise a connecting portion 211, an atomization mouth portion 212, and a base portion 213. The base portion 213 and the atomization mouth portion 212 can be located at opposite ends of the connecting portion 211 in the axial direction, respectively, and the three portions define a cavity for accommodating the liquid storage assembly 23.

[0048] As shown in Figure 1 andFigure 2 As shown, when the atomizer module 20 is inserted into the atomizer accommodating cavity 50, the atomizing nozzle portion 212 is exposed to the first end of the shell 10 and forms an air outlet passage 2121 for user to draw. The base portion 213 is located at one end of the atomizer accommodating cavity 50 close to the main control module 40, and a connecting hole 2131 can be defined on the base portion 213 for electrical connection between the atomizing assembly 22 and the main control module 40.

[0049] It should be understood that the atomizing nozzle portion 212, the connecting portion 211, and the base portion 213 can be detachably or non-detachably connected together by thread connection, bolt connection, glue bonding, buckle connection, or one-piece forming, which is not specifically limited herein.

[0050] In some embodiments, referring to Figure 3 and Figure 4 the outer contour size of the atomizing nozzle portion 212 at one end close to the connecting portion 211 is greater than the outer contour size of the connecting portion 211 at one end close to the atomizing nozzle portion 212, and the size difference between the contours can make the outer surface of the atomizing nozzle portion 212 smoothly transition with the outer surface of the first end of the shell 10 when the atomizer module 20 is inserted into the atomizer accommodating cavity 50. Such a configuration can serve as a limiting function after assembly in the process of inserting the atomizer module 20, and can also improve the appearance and smoothness of the outer surface of the electronic atomization device 1, thereby improving the user experience.

[0051] In some embodiments, the outer contour size of the connecting portion 211 at one end close to the atomizing nozzle portion 212 can be at least partially segmented and slightly greater than the contour size of the chamber wall of the atomizer accommodating cavity 50. When the atomizer shell 21 is inserted into the atomizer accommodating cavity 50, the connecting portion 211 can be in interference fit with the chamber wall of the atomizer accommodating cavity 50 to improve the stability of the assembly therebetween.

[0052] As shown, Figure 2 In some embodiments, the liquid storage assembly 23 can include a liquid storage shell 231, the inside of which can be defined with a liquid storage cavity 2311 and an atomizing cavity 2312 in liquid communication with the liquid storage cavity 2311. The liquid storage cavity 2311 stores liquid substrate therein, and the atomizing assembly 22 is arranged in the atomizing cavity 2312 for atomizing the liquid substrate conducted from the liquid storage cavity 2311 into the atomizing cavity 2312. The electronic atomization device 1 can also be defined with an air inlet hole (not shown in the figure), and the atomizing cavity 2312 can be in communication with the air inlet hole and the air outlet passage 2121, respectively. During user suction, gas can enter the atomizing cavity 2312 from the air inlet hole, mix with the atomized liquid substrate in the atomizing cavity 2312, and flow out of the air outlet passage 2121 together.

[0053] The side wall of the liquid storage shell 231 can be spaced apart from the atomization shell 21, so as to facilitate production and manufacturing, and to achieve the temperature insulation effect through the gap between the liquid storage shell 231 and the atomization shell 21.

[0054] In some embodiments, the liquid storage assembly 23 can further include a liquid storage member 232, which can be made of ceramic, cotton structure or other porous materials with a plurality of capillary channels, and is filled in the liquid storage cavity 2311. The liquid storage member 232 can store the liquid substrate through the internal porous channels.

[0055] In some embodiments, the atomization assembly 22 can include a liquid guide member 221 and an atomization member 222. The liquid guide member 221 is arranged in the atomization cavity 2312 and can guide the liquid substrate in the liquid storage cavity 2311. The atomization member 222 is arranged on the liquid guide member 221 and can atomize the liquid substrate around it when powered.

[0056] It should be understood that when the liquid storage assembly 23 includes the liquid storage member 232, the liquid guide member 221 can be arranged in close contact with the chamber wall of the atomization cavity 2312 defined by the liquid storage member 232. The liquid guide member 221 can be provided with a liquid guide hole to facilitate the conduction of the liquid substrate. Alternatively, the liquid guide member 221 can be made of porous material with capillary channels to achieve liquid guidance through capillary action. When the liquid storage assembly 23 does not include the liquid storage member 232, the liquid guide member 221 can also be used to separate the liquid storage cavity 2311 and the atomization cavity 2312.

[0057] The atomization member 222 can also be in the form of a sheet, arranged on the liquid guide member 221. It can also be in the form of a wire, a block or a column, and other shapes, which are not limited here.

[0058] In some embodiments, the liquid storage assembly 23 can further include a first liquid absorption member 233 and a second liquid absorption member 234. The first liquid absorption member 233 and the second liquid absorption member 234 can be arranged on the liquid storage shell 231 respectively, to absorb the leaked liquid substrate and prevent the liquid substrate from leaking to the shell 10 through the gap, thereby further improving the user experience.

[0059] Specifically, the first liquid absorption member 233 can be arranged between the liquid storage shell 231 and the atomization nozzle 212 to prevent the liquid substrate from leaking from the connection between the atomization cavity 2312 and the air outlet passage 2121. Since the atomization assembly 22 needs to be electrically connected to the main control module 40, an electrical connection hole needs to be reserved at one end of the liquid storage shell 231 close to the battery module 30. Therefore, the second liquid absorption member 234 can be arranged between the liquid storage shell 231 and the base 213 to prevent the liquid substrate from leaking from the reserved electrical connection hole.

[0060] Continuing to refer to Figure 2In some embodiments, the battery module 30 can include a battery 31 and a battery shell 32. At least part of the battery 31 is arranged in the battery shell 32 and can be electrically connected to the main control module 40 to supply power to the atomizer module 20. The battery shell 32 is detachably inserted into the battery receiving cavity 60 along the axial direction of the shell 11 from the first end thereof.

[0061] Specifically, the shape of the battery shell 32 is adapted to the shape of the cavity of the battery receiving cavity 60 to achieve the guiding effect of the insertion process by the cavity side wall.

[0062] In some embodiments, the shape of the battery shell 32 can be adapted to the shape of the cavity of the battery receiving cavity 60 so that the side wall of the battery shell 32 is in surface contact with the cavity wall of the battery receiving cavity 60 to achieve the guiding effect of the insertion process by the cavity side wall. Specifically, it can be provided in various shapes such as cylindrical, polygonal cylindrical, irregular cylindrical, pie-shaped, semi-circular cylindrical, elliptical cylindrical, etc., which are not limited here. Of course, the side wall of the battery shell 32 can also be spaced apart from at least part of the cavity wall of the battery receiving cavity 60.

[0063] Referring to Figure 3 and Figure 4 In some embodiments, the battery shell 32 can include a main body portion 321 and a fitting portion 322. The main body portion 321 is hollow inside and is detachably inserted into the battery receiving cavity 60 from the first end. The fitting portion 322 is capped at one end of the main body portion 321 and is exposed to the battery receiving cavity 60 to cap the battery in the main body portion 321.

[0064] Specifically, as shown in Figure 2 and Figure 4 The end of the main body portion 321 away from the fitting portion 322 can be through, so that the battery shell 32 as a whole has an open end and a closed end structure, and is detachably buckled in the battery receiving cavity 60. One end of the battery 31 can extend from the through end of the main body portion 321 to the main control module 40 to achieve electrical connection therewith.

[0065] The fitting portion 322 can be arched and protrude from the battery receiving cavity 60. The outer contour size of the end connected to the main body portion 321 of the fitting portion 322 can be slightly larger than the outer contour size of the end connected to the main body portion 321 of the fitting portion 322, and is smoothly connected with the outer surface of the shell 10 to further improve the appearance of the electronic atomization device 1 and the smoothness of the outer surface, thereby improving the user's experience.

[0066] Further, the outer profile of the main body portion 321 near the end of the fitting portion 322 is larger than the outer profile of the main body portion 321 away from the end of the fitting portion 322. When the battery shell 32 is inserted into the battery accommodating cavity 60, the change in the outer profile of the main body portion 321 can be such that at least part of the main body portion 321 can be in interference fit with the cavity wall of the battery accommodating cavity 60 (i.e. the outer shell 10), so as to improve the firmness of the assembly of the battery module 30 and the outer shell 10, and avoid accidental falling.

[0067] It needs to be understood that the main body portion 321 and the fitting portion 322 can be detachably or non-detachably connected together by means of threaded connection, bolted connection, glue bonding, interference fit, snap connection, one-piece forming, etc., which is not specifically limited here.

[0068] In some other alternative embodiments, the fitting portion 322 can also be located inside the battery accommodating cavity 60 and cover the top end thereof, and smoothly transitionally connected with the outer surface of the outer shell 10.

[0069] In some other alternative embodiments, the end of the main body portion 321 away from the fitting portion 322 can also be a closed end, and the battery 31 can be integrally arranged in the battery shell 32. A through hole is reserved on the closed end of the main body portion 321, so as to facilitate the electrical connection of the battery 31 with the master control module 40 through flexible wires or rigid conductive structures.

[0070] As shown in Figure 4 In some embodiments, at least one guide structure 3201 is arranged on the outer side of the battery shell 32. The guide structure 3201 is movably fitted with the partition structure 12 along the extension direction of the partition structure 12, so as to realize the guiding and limiting of the battery shell 32 during the insertion process.

[0071] Specifically, the guide structure 3201 can be a longitudinal guide groove, and the number thereof can be adapted to the number of the partition structure 12. In the embodiment shown in Figure 4 there are two, respectively corresponding to the partition structures 12 on the two opposite side walls of the shell 11. During the disassembly process, the guide structure 3201 and the partition structure 12 can move axially relative to each other, thereby realizing the guiding and limiting effect.

[0072] As shown in Figure 2 In some embodiments, part of the side wall of the battery shell 32 can be arranged in close contact with part of the side wall of the atomization shell 21, so as to improve the utilization rate of the installation cavity 100.

[0073] Hereinafter, the part of the side wall of the battery shell 32 in close contact with the atomization shell 21 is defined as a first side wall 320, and the remaining side wall is defined as a second side wall. The part of the side wall of the atomization shell 21 in close contact with the battery shell 32 is defined as a third side wall 210, and the remaining side wall is defined as a fourth side wall.

[0074] Among them, the first sidewall 320 and the third sidewall 210 are both planar wall structures, while the second sidewall and the fourth sidewall are curved wall structures. Figure 4 As shown, the first sidewall 320 partially belongs to the main body 321 and partially belongs to the mating part 322. Figure 3 As shown, the third sidewall 210 partly belongs to the connecting part 211 and partly belongs to the atomizing nozzle part 212.

[0075] In some other alternative embodiments, the first sidewall 320 and the third sidewall 210 may also be configured as curved wall structures with mutually parallel axes. The third sidewall and / or the fourth sidewall may also be configured as planar wall structures.

[0076] like Figure 4 As shown, in some embodiments, the guide structure 3201 is located on both sides of the first sidewall 320 and the second sidewall.

[0077] In some other alternative embodiments, when the partition structure 12 is located within the battery housing cavity 60, the guide structure 3201 may also be correspondingly disposed on the second sidewall. When the partition structure 12 is a concave groove structure, the guide structure 3201 may also be correspondingly disposed as a protrusion.

[0078] In some other alternative embodiments, the guide structure 3201 can also be disposed on the atomizing shell 21, located on both sides where the third sidewall 210 connects to the fourth sidewall. Of course, when the partition structure 12 is located inside the atomizer housing cavity 50, the guide structure 3201 can also be disposed on the fourth sidewall.

[0079] In some embodiments, the atomizing shell 21 and the battery shell 32 can also be detachably connected.

[0080] Specifically, such as Figure 3 and Figure 4 As shown, one of the first sidewall 320 and the third sidewall 210 is provided with an assembly protrusion 323, and the other is provided with an assembly groove 2101. When the atomizer module 20 and the battery module 30 are respectively inserted into the mounting cavity 100, the assembly protrusion 323 is detachably limited within the assembly groove 2101, realizing the snap-fit ​​limitation between the atomizer shell 21 and the battery shell 32.

[0081] exist Figure 3 and Figure 4 In the embodiment shown, the assembly groove 2101 is formed on the third sidewall 210, and the assembly protrusion 323 is disposed on the first sidewall 320.

[0082] In some embodiments, a clearance slot 2102 can also be formed on the third side wall 210, which can be axially spaced from one end of the assembly slot 2101, for providing clearance for the assembly protrusion 323 during the insertion process, so as to avoid the assembly protrusion 323 abutting against the first side wall 320, thus failing to be inserted in place.

[0083] Specifically, the clearance slot 2102 can be arranged at one end of the assembly slot 2101 close to the base portion 213. During the assembly process, the battery module 30 can be inserted first, and then the atomizer module 20. Of course, when the atomizer module 20 is inserted first and then the battery module 30 during the assembly process, the clearance slot 2102 can be arranged at one end of the assembly slot 2101 away from the base portion 213.

[0084] In some embodiments, the clearance slot 2102 close to one end of the assembly slot 2101 can gradually decrease in depth, so as to facilitate the assembly protrusion 323 to smoothly move out of the clearance slot 2102 during the insertion process.

[0085] In other some alternative embodiments, the first side wall 320 and the third side wall 210 can also be spaced apart. The partition structure 12 is clamped therebetween to achieve the blocking effect.

The base 41 may also be entirely disposed within the mounting cavity 100; in this embodiment, the control element 42 may be entirely located within the mounting cavity 100.

[0091] like Figure 3 As shown, in some embodiments, the base 41 may include a seat body 411 and at least one first limiting portion 412. One end of the seat body 411 is through-hole and partially inserted into the second end of the housing 10, and the connecting groove 4111 is formed on the seat body 411.

[0093] Specifically, the two ends of the battery 31 can abut against the end walls of the second limiting part 324 and the seat 411 respectively along the axial direction, thereby achieving axial limiting. The first limiting part 412 is cylindrical and is used to fit on the outer periphery of the end of the battery 31 to limit the battery 31 in the circumferential direction.

[0094] In some other alternative embodiments, the first limiting part 412 may also be configured as a plurality of protrusions located on the end wall or side wall of the seat 411, which are spaced apart on the outer periphery of the end of the battery 31, and the cooperation between the protrusions and protrusions can also achieve circumferential limiting of the battery 31.

[0095] In some other alternative embodiments, the second limiting part 324 may also be disposed on the outer periphery of the battery 31 to limit the battery 31 in the circumferential direction. The first limiting part 412 may only abut against the end of the battery 31, and cooperate with the battery casing 32 to limit the battery 31 in the axial direction.

[0096] like Figure 2As shown, in some embodiments, the control element 42 can be arranged in the base 41 corresponding to the position of the atomizer receiving cavity 50, so as to be electrically connected with the atomization assembly 22. The end of the battery 31 away from the fitting portion 322 can extend into the base 41, so as to be electrically connected with the control element 42.

[0097] Specifically, the control element 42 can include a main control board 421, an airflow sensor 422, and an electrode column 423. The main control board 421 can be arranged with a control unit, the electrode column 423 can be arranged on the main control board 421 and electrically connected with the control unit, and used to be inserted into the connecting hole 2131 of the base portion 213, so as to be electrically connected with the atomization assembly 22. The airflow sensor 422 is arranged on the main control board 421 and electrically connected with the control unit, and used to sense the change of suction of the user through negative pressure, so as to control the atomization of the atomization assembly 22.

[0098] In other some alternative embodiments, the electrode column 423 can also be arranged on the atomizer module 20, for example, can be fixed in the connecting hole 2131. When the atomizer module 20 and the main control module 40 are respectively inserted into the shell 10, the electrode column 423 can abut against the main control board 421, so as to be electrically connected with the control unit.

[0099] As shown, Figure 3 in some embodiments, the base 41 can also include at least one third limiting portion 413, which can be arranged at a position corresponding to the atomizer receiving cavity 50 of the seat body 411, and used to limit the position of the control element 42 in the base 41.

[0100] Specifically, the third limiting portion 413 can adopt a plurality of rib plates protruding from the inner wall surface of the seat body 411, which can be arranged with clamping grooves to support and clamp the main control board 421, so as to limit the position on the seat body 411.

[0101] In other some alternative embodiments, the third limiting portion 413 can also be arranged in a columnar or other shape structure, and the main control board 421 and the third limiting portion 413 can also be connected and limited by means of bolt connection.

[0102] As shown, Figure 2 and Figure 4 in some embodiments, the base portion 213 of the atomization shell 21 opposite to the connecting portion 211 can also be arranged with a sensor receiving member 214, which can receive the airflow sensor 422 after the main control module 40 and the atomizer module 20 are respectively inserted into the shell 10.

[0103] Specifically, the sensor housing 214 can be substantially cylindrically arranged, and the inner profile thereof is adapted to the outer profile of the airflow sensor 422. When the main control module 40 and the atomizer module 20 are respectively inserted into place, the sensor housing 214 and the airflow sensor 422 jointly build a relatively closed cavity, and the airflow sensor 422 can detect the negative pressure change in the cavity.

[0104] Further, the base portion 213 can further be formed with a negative pressure hole 2132 in communication with the atomization cavity 2312, and the negative pressure hole 2132 can also be in communication with the cavity for detecting the negative pressure by the airflow sensor 422. During the user's suction, the cavity will generate a negative pressure change according to the suction condition. Further, the airflow sensor 422 can feed back to the main control unit according to the detected negative pressure change of the cavity, and correspondingly adjust the atomization control of the atomization assembly 22.

[0105] It should be understood that the airflow sensor 422 can be implemented by using an existing microphone or MEMS sensor, which is not specifically limited here.
