Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of atomization, and more particularly to a key structure, a power supply device, and an aerosol generating device. BACKGROUND

[0002] An aerosol generating device refers to a device for heating an aerosol generating substrate to atomize the aerosol generating substrate to form an aerosol. The aerosol formed by atomizing the aerosol generating substrate can be used for a user to smoke.

[0003] The aerosol generating device is usually provided with a switching member, a magnetic attraction assembly, and a pressing assembly. The magnetic attraction assembly and the switching member are oppositely arranged. The pressing assembly includes a fixing member and a magnetic attraction member attached to the fixing member. The magnetic attraction member is magnetically attracted to the magnetic attraction assembly. When the aerosol generating device is used, the user can press the pressing assembly. The magnetic attraction assembly is driven by the pressing assembly to move toward the switching member to trigger the switching member, so that the aerosol generating device is started to perform atomization work.

[0004] It should be noted that the magnetic attraction member and the magnetic attraction assembly are magnetically attracted to each other to achieve detachable connection between the magnetic attraction assembly and the pressing assembly. In this way, the pressing assembly can be disassembled and replaced according to needs and preferences.

[0005] However, the magnetic attraction member and the fixing member are fixed by adhesion, which limits the fixing firmness between the magnetic attraction member and the fixing member. This makes the magnetic attraction member have a high risk of falling off the fixing member. Moreover, during the disassembly of the pressing assembly, the magnetic attraction member has a tendency to move away from the fixing member under the magnetic attraction of the magnetic attraction assembly, thereby easily falling off the fixing member.

[0039] The following will be described in detail in combination with specific drawings and embodiments: Please see Figures 1 to 3 Wherein, Figure 1 The three-dimensional structure diagram of the power supply device provided by some embodiments of the present application Figure 2 For Figure 1 The sectional view along A-A, Figure 3 For Figure 2 The enlarged view at B in FIG. 10. The key structure 10 provided by the embodiments of the present application includes a shell assembly 11, a switch piece 12, a magnetic attraction assembly 13 and a pressing assembly 14. The switch piece 12 is arranged in the shell assembly 11. The magnetic attraction assembly 13 is arranged in the shell assembly 11, and the magnetic attraction assembly 13 is arranged opposite to the switch piece 12 along a first direction X. The magnetic attraction assembly 13 is used to move towards the switch piece 12 along the first direction X to trigger the switch piece 12. The pressing assembly 14 includes a fixing piece 141, a first magnetic attraction piece 142 and a pressing piece 143. The fixing piece 141 is sleeved on the outer periphery of the first magnetic attraction piece 142, and the fixing piece 141 is in interference fit with the first magnetic attraction piece 142. The first magnetic attraction piece 142 is arranged on the side of the magnetic attraction assembly 13 away from the switch piece 12 along the first direction X, and the first magnetic attraction piece 142 is in magnetic attraction with the magnetic attraction assembly 13. The pressing piece 143 is arranged on the fixing piece 141, and at least part of the pressing piece 143 is exposed outside the shell assembly 11.

[0040] The shell assembly 11 is the shell structure of the key structure 10. Wherein, when the key structure 10 is applied to the power supply device, the shell assembly 11 can be the shell structure of the power supply device.

[0041] The switch piece 12 refers to a semiconductor device that makes the circuit closed or disconnected when triggered. Wherein, the switch piece 12 can be a touch switch or a key switch. Wherein, when the key structure 10 is applied to the power supply device, when the switch piece 12 is triggered, the power supply device starts and supplies power to the atomization assembly to make the atomization assembly work.

[0042] Magnetic component 13 refers to a component structure with magnetic attraction capability.

[0043] The first direction X is the approximate distribution direction of the magnetic attraction component 13 and the switch component 12. At least a portion of the magnetic attraction component 13 is positioned directly opposite the switch component 12 along the first direction X.

[0044] The magnetic component 13 is used to move along the first direction X toward the switch element 12 to trigger the switch element 12. This means that at least a portion of the magnetic component 13 facing the switch element 12 along the first direction X can move along the first direction X toward the switch element 12, such that the at least portion of the magnetic component 13 facing the switch element 12 along the first direction X touches or presses the switch element 12, thereby triggering the switch element 12. Specifically, when the switch element 12 is a touch switch, the switch element 12 is triggered when the at least portion of the magnetic component 13 facing the switch element 12 along the first direction X moves toward the switch element 12 to touch it; when the switch element 12 is a push-button switch, the switch element 12 is triggered when the at least portion of the magnetic component 13 facing the switch element 12 along the first direction X moves toward the switch element 12 to press it.

[0045] Press component 14 refers to the component structure of button structure 10 for users to press. Specifically, the press member 143 of press component 14 is for users to press.

[0046] The fastener 141 refers to the component of the pressing assembly 14 used to mount the first magnetic member 142 and the pressing member 143.

[0047] The fastener 141 is sleeved around the outer periphery of the first magnetic attractor 142, meaning that at least a portion of the fastener 141 is sleeved around the outer periphery of the first magnetic attractor 142. Specifically, at least a portion of the fastener 141 is sleeve-shaped and sleeves around the outer periphery of the first magnetic attractor 142. In some possible designs, such as... Figures 1 to 3 As shown, one portion of the fastener 141 is sleeve-shaped and fitted around the outer periphery of the first magnetic member 142; another portion of the fastener 141 is located on at least one side of the first magnetic member 142 along the first direction X. For example, the first magnetic member 142 and the second protrusion 1413 of the fastener 141 (described below) are distributed along the first direction X. Alternatively, in some other possible designs, the fastener 141 is sleeve-shaped and fitted around the outer periphery of the first magnetic member 142, and a portion of the fastener 141 is not located on at least one side of the first magnetic member 142 along the first direction X.

[0048] The first magnetic attraction member 142 refers to a component with magnetic attraction capability. The first magnetic attraction member 142 can be a magnet, and the magnetic attraction member on the magnetic attraction assembly 13 can be a magnet or a metal structure. Alternatively, the first magnetic attraction member 142 can be a metal structure, and the magnetic attraction member on the magnetic attraction assembly 13 can be a magnet. The magnetic attraction member on the magnetic attraction assembly 13 is referred to as the second magnetic attraction member 132 below.

[0049] The fixing member 141 is in interference fit with the first magnetic attraction member 142, that is, the inner peripheral wall of the fixing member 141 and the outer peripheral wall of the first magnetic attraction member 142 abut against and press each other, achieving firm fixing of the fixing member 141 and the first magnetic attraction member 142.

[0050] In the first direction X, the magnetic attraction assembly 13 is arranged between the switch member 12 and the first magnetic attraction member 142. At least part of the first magnetic attraction member 142 is arranged opposite the magnetic attraction assembly 13 along the first direction X, and the side of the first magnetic attraction member 142 along the first direction X towards the magnetic attraction assembly 13 is exposed outside the fixing member 141, so that the first magnetic attraction member 142 and the magnetic attraction assembly 13 abut against and magnetically attract each other along the first direction X.

[0051] The pressing member 143 is arranged on the fixing member 141. Specifically, at least part of the pressing member 143 can be arranged on the side of the first magnetic attraction member 142 away from the magnetic attraction assembly 13 along the first direction X, so that the pressing member 143 is exposed outside the housing assembly 11, facilitating the pressing member 143 being pressed by the user.

[0052] At least part of the pressing member 143 is exposed outside the housing assembly 11. Specifically, at least part of the pressing member 143 on the side away from the magnetic attraction assembly 13 along the first direction X is exposed outside the housing assembly 11. That is, at least part of the pressing member 143 is exposed outside the side of the housing assembly 11 along the first direction X. In this way, the user can easily apply a force along the first direction X to the pressing member 143, that is, the user can easily press the pressing member 143 along the first direction X.

[0053] It can be understood that the housing assembly 11 is provided with a key space 107, the switch member 12 is fixed in the key space 107, the magnetic attraction assembly 13 is installed in the key space 107, and part of the pressing assembly 14 is located in the key space 107.

[0054] The key structure 10 provided by the embodiment of the application can be pressed by the user through the part of the pressing member 143 exposed outside the housing assembly 11, specifically by pressing the pressing member 143 towards the switch member 12. In this way, the fixing member 141 and the first magnetic attraction member 142 can be driven by the pressing member 143 to move towards the switch member 12 along the first direction X, so that the magnetic attraction assembly 13 is driven by the first magnetic attraction member 142 to move towards the switch member 12 along the first direction X, thereby triggering the switch member 12 by the magnetic attraction assembly 13.

[0055] The fixing member 141 is sleeved on the outer periphery of the first magnetic member 142, and the fixing member 141 and the first magnetic member 142 are in interference fit, thereby improving the fixing strength between the first magnetic member 142 and the fixing member 141, and thus reducing the risk of the first magnetic member 142 falling off the fixing member 141.

[0056] It should be noted that in the scheme in which the magnetic member is bonded to the fixing member 141, the fixing member 141 and the magnetic member are fixed by bonding, so that the bonding firmness between the fixing member 141 and the magnetic member is limited. In the process of bonding the magnetic member to the fixing member 141, the glue between the fixing member 141 and the magnetic member is easy to overflow, so that the glue between the fixing member 141 and the magnetic member is limited, thereby further reducing the bonding firmness of the fixing member 141 and the magnetic member. In the key structure 10 provided by the embodiment of the application, the fixing member 141 and the first magnetic member 142 are in interference fit, and glue is not arranged between the fixing member 141 and the first magnetic member 142, which can solve the problem that the bonding firmness of the fixing member 141 and the magnetic member is further reduced due to glue overflow. Moreover, the arrangement operation of the glue is omitted, so that the assembly steps of the pressing assembly 14 are very simple and efficient.

[0057] In some embodiments, the first magnetic member 142 is a magnet.

[0058] In this way, the magnetic attraction strength between the first magnetic member 142 and the magnetic assembly 13 is high, thereby improving the firmness of the detachable connection between the pressing assembly 14 and the magnetic assembly 13, and solving the risk of the pressing assembly 14 being separated.

[0059] It should be noted that when the first magnetic member 142 is a magnet, the weight of the first magnetic member 142 is large. On the basis that the first magnetic member 142 is a magnet, if the first magnetic member 142 is bonded to the fixing member 141, the first magnetic member 142 and the fixing member 141 are difficult to be firmly combined, so that the first magnetic member 142 is very easy to fall off the fixing member 141. By interference fit between the first magnetic member 142 and the fixing member 141, the firmness of the combination between the first magnetic member 142 and the fixing member 141 can be improved, thereby greatly reducing the risk of the first magnetic member 142 falling off the fixing member 141, so that the scheme of interference fit between the first magnetic member 142 and the fixing member 141 is very suitable for the scheme in which the first magnetic member 142 is a magnet.

[0060] In some embodiments, the fixing member 141 is a plastic structure, and the fixing member 141 and the first magnetic member 142 are injection molded.

[0061] Specifically, the first magnetic member 142 is arranged in the injection mold as an insert, and an injection operation is performed to obtain the fixing member 141 in interference fit with the first magnetic member 142. That is, the fixing member 141 is integrally injection molded with the first magnetic member 142.

[0062] In this way, on the one hand, the combination of the first magnetic member 142 and the fixing member 141 is greatly improved, and the risk of the first magnetic member 142 falling off the fixing member 141 is greatly reduced. In this way, the first magnetic member 142 can be a magnet, which is used to improve the connection reliability of the magnetic assembly 13 and the pressing assembly 14. On the other hand, the fixing member 141 is integrally fixed with the first magnetic member 142 in the incoming material of the key structure 10, which reduces the assembly steps between the parts of the pressing assembly 14, thereby simplifying the assembly operation of the key structure 10.

[0063] It should be noted that when the first magnetic member 142 is a magnet, the injection operation needs to be performed under high temperature conditions, and in order to ensure the magnetic force of the first magnetic member 142, the first magnetic member 142 can be magnetized after the first magnetic member 142 and the fixing member 141 are integrally injection molded.

[0064] In some embodiments, please refer to Figures 3 to 5 , and in combination with other drawings. Among them, Figure 4 is a perspective view of the pressing assembly 14 of the key structure 10 provided by some embodiments of the present application, Figure 5 is Figure 4 a perspective view of the fixing member 141 of the pressing assembly 14 provided by some embodiments of the present application. The first magnetic member 142 includes a magnetic main body 1421 and a first protruding portion 1422, and the first protruding portion 1422 is arranged on the outer periphery of the magnetic main body 1421. The fixing member 141 is sleeved on the outer periphery of the magnetic main body 1421, and the fixing member 141 is in interference fit with the magnetic main body 1421. The inner peripheral wall of the fixing member 141 is provided with a first limiting groove 101, and the first protruding portion 1422 is limited between the two side groove walls of the first limiting groove 101 along the first direction X, and the first protruding portion 1422 is in interference fit with the first limiting groove 101.

[0065] The magnetic main body 1421 and the first protruding portion 1422 are two parts of the first magnetic member 142, and both the magnetic main body 1421 and the first protruding portion 1422 have magnetic attraction capability. Among them, the first protruding portion 1422 can be an annular structure surrounding the outer periphery of the magnetic main body 1421, or the first protruding portion 1422 can also be a non-annular structure.

[0066] The magnetic body 1421 is in interference fit with the fixing member 141, and the first protrusion 1422 is in interference fit with the first limiting groove 101, so that the fixing member 141 is sleeved on the outer periphery of the magnetic body 1421 and the first protrusion 1422, and the fixing member 141 is in interference fit with the magnetic body 1421 and the first protrusion 1422.

[0067] The first limiting groove 101 is a groove structure formed by the inner peripheral wall of the fixing member 141 being recessed. When the first protrusion 1422 is in annular structure, the first limiting groove 101 is an annular groove; when the first protrusion 1422 is in non-annular structure, the first limiting groove 101 is also a non-annular groove. That is, the first protrusion 1422 is matched with the first limiting groove 101.

[0068] The first protrusion 1422 is limited between the two side groove walls of the first limiting groove 101 in the first direction X, so that the first protrusion 1422 cannot move relative to the fixing member 141 towards the magnetic assembly 13 in the first direction X, nor can it move relative to the fixing member 141 away from the magnetic assembly 13 in the first direction X. That is, under the limiting action of the first limiting groove 101, the first magnetic member 142 cannot move relative to the fixing member 141 towards the magnetic assembly 13 in the first direction X, nor can it move relative to the fixing member 141 away from the magnetic assembly 13 in the first direction X.

[0069] In this way, the combination of the first magnetic member 142 and the fixing member 141 is further improved. Specifically, the combination strength of the first magnetic member 142 and the fixing member 141 in the first direction X is further improved. In this way, when the pressing assembly 14 is disassembled from the magnetic assembly 13, the problem that the first magnetic member 142 is separated from the fixing member 141 in the first direction X under the magnetic attraction of the magnetic assembly 13 can be solved. In this way, the risk of the first magnetic member 142 falling off the fixing member 141 is further reduced.

[0070] It should be noted that the magnetic body 1421 and the first protrusion 1422 are arranged as inserts in the injection mold, and the injection operation is performed to obtain the fixing member 141 which is in interference fit with the magnetic body 1421 and the first protrusion 1422. That is, the magnetic body 1421 is injection connected with the fixing member 141, and the first protrusion 1422 is injection connected with the fixing member 141. That is, the fixing member 141 is integrally injection molded with the magnetic body 1421 and the first protrusion 1422.

[0071] In some embodiments, please refer to Figures 3 to 5, and in combination with other drawings. The fixing member 141 comprises a fixing body 1411 and a plurality of wrapping portions 1412. The fixing body 1411 is sleeved on the outer periphery of the first magnetic member 142, and the fixing body 1411 is in interference fit with the first magnetic member 142. The plurality of wrapping portions 1412 are arranged on one end of the fixing body 1411 close to the switch member 12 along the first direction X, the plurality of wrapping portions 1412 are arranged at intervals along the circumferential direction, and the plurality of wrapping portions 1412 wrap the outer periphery of the first magnetic member 142.

[0072] The fixing body 1411 is the main body part of the fixing member 141. The fixing body 1411 and the wrapping portions 1412 can both be injection molded structures. When the wrapping portions 1412 are injection molded structures, the wrapping portions 1412 have a certain elastic effect.

[0073] It can be understood that the plurality of wrapping portions 1412 are arranged at intervals along the circumferential direction and wrap the outer periphery of the first magnetic member 142, so that the whole formed by the plurality of wrapping portions 1412 is in interference fit with the first magnetic member 142. That is, the wrapping portions 1412 abut against the outer periphery of the first magnetic member 142 and press the first magnetic member 142.

[0074] By arranging the plurality of wrapping portions 1412 at intervals along the circumferential direction, the wrapping portions 1412 can more firmly abut against and press the first magnetic member 142 under the elastic effect of the wrapping portions 1412, which further improves the combination firmness between the fixing member 141 and the first magnetic member 142.

[0075] In some possible designs, as shown in Figures 3 to 5 , the fixing body 1411 and the wrapping portions 1412 surround to form the first limiting groove 101. Alternatively, in some other possible designs, the first limiting groove 101 is formed on the inner peripheral wall of the fixing body 1411.

[0076] It should be noted that the fixing body 1411 is injection molded with the first magnetic member 142, and the wrapping portions 1412 are injection molded with the first magnetic member 142. That is, the fixing body 1411, the wrapping portions 1412, and the first magnetic member 142 are integrally injection molded.

[0077] In some embodiments, please refer to Figures 3 to 5 , and in combination with other drawings. The inner peripheral wall of the fixing member 141 is provided with a second protrusion 1413, and the first magnetic member 142 and the pressing member 143 are respectively arranged on opposite sides of the second protrusion 1413 along the first direction X.

[0078] Specifically, the second protrusion 1413 is arranged on the inner peripheral wall of the fixing body 1411.

[0079] The second protruding part 1413 can also be an injection molding structure. Specifically, the second protruding part 1413 is injection molded with the first magnetic member 142, that is, the fixed body 1411, the wrapping part 1412, the second protruding part 1413, and the first magnetic member 142 are integrally injection molded.

[0080] The second protruding part 1413 can be an annular structure arranged around the inner circumferential wall of the fixed body 1411, or a non-annular structure.

[0081] Specifically, the first magnetic member 142 and the pressing member 143 are arranged on opposite sides of the second protruding part 1413 along the first direction X, the first magnetic member 142 abuts against the second protruding part 1413 along the first direction X, and the pressing member 143 is arranged on the second protruding part 1413 along the first direction X.

[0082] In this way, the first magnetic member 142 and the pressing member 143 are spaced apart by the second protruding part 1413, so that the first magnetic member 142 and the pressing member 143 are arranged apart along the first direction X. In this way, when the user presses the pressing member 143, the pressing member 143 will not push the first magnetic member 142 along the first direction X under the limiting action of the second protruding part 1413, so that the first magnetic member 142 will not be pushed out of the fixed member 141 by the pressing member 143, thereby further reducing the risk of the first magnetic member 142 being pulled out of the fixed member 141.

[0083] In some possible designs, the pressing member 143 can be bonded to the second protruding part 1413. Based on this, if the glue between the pressing member 143 and the second protruding part 1413 overflows during the bonding process of the pressing member 143 to the second protruding part 1413, the glue can fill the space between the pressing member 143 and the first magnetic member 142, thereby facilitating the bonding of the pressing member 143 and the second protruding part 1413.

[0084] In some embodiments, please refer to Figures 3 to 5 , and in combination with other drawings. The fixed member 141 is sleeved on the outer periphery of the pressing member 143. Specifically, the fixed body 1411 is sleeved on the outer periphery of the pressing member 143.

[0085] In this way, the fixed member 141 can limit the pressing member 143 in the radial direction, thereby improving the bonding strength of the pressing member 143 and the fixed member 141.

[0086] The pressing member 143 can also be bonded to the inner circumferential wall of the fixed body 1411.

[0087] In some embodiments, please refer to Figures 3 to 7 , and in combination with other drawings. Wherein, Figure 6 is an exploded view of Figure 1 ,Figure 7 For Figure 6 The enlarged view at C. The housing assembly 11 is provided with a through hole 102 along the first direction X, and the fixing member 141 is arranged in the through hole 102. The inner peripheral wall of the through hole 102 is provided with a first step portion 1111, and the outer peripheral wall of the fixing member 141 is provided with a second step portion 1414, which is located on the side of the first step portion 1111 away from the switch member 12 along the first direction X, and the second step portion 1414 is arranged opposite to the first step portion 1111 along the first direction X.

[0088] It can be understood that the side wall of the housing assembly 11 is provided with a through hole 102 along the first direction X, which is communicated with the key space 107. The fixing member 141 is arranged in the through hole 102 along the first direction X.

[0089] Specifically, the second step portion 1414 is arranged on the outer peripheral wall of the fixing body 1411.

[0090] It can be understood that the second step portion 1414 is located on the side of the first step portion 1111 away from the switch member 12 along the first direction X, and the second step portion 1414 is arranged opposite to the first step portion 1111 along the first direction X, and the second step portion 1414 is spaced apart from the first step portion 1111 along the first direction X. In this way, during the process that the user presses the pressing member 143 to drive the fixing member 141, the first magnetic attraction member 142 and the magnetic attraction assembly 13 to move towards the switch member 12 along the first direction X to trigger the switch member 12, the first step portion 1111 can limit the second step portion 1414, that is, the first step portion 1111 can limit the movement stroke of the fixing member 141 moving towards the switch member 12 along the first direction X, so that the pressing assembly 14 and the magnetic attraction assembly 13 cannot move towards the switch member 12 along the first direction X unlimitedly, thereby solving the problem that the switch member 12 is damaged by the magnetic attraction assembly 13.

[0091] The first step portion 1111 can be a ring structure or a non-ring structure. The second step portion 1414 can be a ring structure or a non-ring structure.

[0092] In some embodiments, please refer to Figure 3 and Figure 8 together with other drawings. Among them, Figure 8A perspective view of the magnetic attraction assembly 13 of the key structure 10 according to some embodiments of the present application is shown in FIG. 1. The magnetic attraction assembly 13 includes a cantilever structure 131 and a second magnetic attraction member 132. The cantilever structure 131 is disposed in the housing assembly 11, and the cantilever structure 131 is disposed opposite the switch member 12 along the first direction X. The cantilever structure 131 is configured to move along the first direction X toward the switch member 12 to trigger the switch member 12. The second magnetic attraction member 132 is disposed on the cantilever structure 131, and the second magnetic attraction member 132 is magnetically attracted to the first magnetic attraction member 142.

[0093] The cantilever structure 131 refers to a structure that is at least partially elastically movable. Specifically, the cantilever structure 131 is mounted in the key space 107, and the second magnetic attraction member 132 is disposed in the key space 107.

[0094] The cantilever structure 131 is disposed opposite the switch member 12 along the first direction X, which means that at least a portion of the cantilever structure 131 is disposed directly opposite the switch member 12 along the first direction X. In this way, when the cantilever structure 131 moves along the first direction X toward the switch member 12, at least a portion of the cantilever structure 131 can trigger the switch member 12.

[0095] The second magnetic attraction member 132 is a component having magnetic attraction properties. When the first magnetic attraction member 142 is a magnet, the second magnetic attraction member 132 can be a metal structure or a magnet. When the first magnetic attraction member 142 is a metal structure, the second magnetic attraction member 132 is a magnet.

[0096] It can be understood that the second magnetic attraction member 132 is exposed on a side of the cantilever structure 131 that is away from the switch member 12 along the first direction X, and the first magnetic attraction member 142 is exposed on a side of the fixed member 141 that is toward the magnetic attraction assembly 13 along the first direction X. In this way, the first magnetic attraction member 142 and the second magnetic attraction member 132 are disposed directly opposite each other along the first direction X and are magnetically attracted to each other.

[0097] In this way, the magnetic attraction assembly 13 can be magnetically attracted to the first magnetic attraction member 142, and the magnetic attraction assembly 13 can move along the first direction X toward the switch member 12 to trigger the switch member 12.

[0098] It should be noted that after the cantilever structure 131 triggers the switch member 12, the user can remove the pressing force on the pressing member 143, and the cantilever structure 131 can move along the first direction X to return to the original position.

[0099] In some embodiments, please refer to Figure 3 and Figure 8, and in conjunction with other figures. The cantilever structure 131 comprises a fixed part 1311, a moving part 1312, and an elastic arm 1313. The fixed part 1311 is fixed in the housing assembly 11. The moving part 1312 is arranged opposite to the switch piece 12 along the first direction X, and the moving part 1312 is configured to move along the first direction X towards the switch piece 12 to trigger the switch piece 12. The second magnetic attraction piece 132 is arranged on the moving part 1312, and the elastic arm 1313 is connected between the fixed part 1311 and the moving part 1312.

[0100] Specifically, the second magnetic attraction piece 132 is arranged on a side of the moving part 1312 away from the switch piece 12 along the first direction X.

[0101] The elastic arm 1313 refers to an arm capable of elastic deformation, so that the moving part 1312 can move along the first direction X relative to the fixed part 1311.

[0102] It should be noted that when the user presses the pressing piece 143, the fixed piece 141 and the first magnetic attraction piece 142 can drive the second magnetic attraction piece 132 and the moving piece to move along the first direction X towards the switch piece 12 to trigger the switch piece 12. At this time, at least part of the elastic arm 1313 moves with the moving piece to make the elastic arm 1313 elastically deform. When the user removes the pressing on the pressing piece 143, the elastic arm 1313 resets the movement to make the moving part 1312, the second magnetic attraction piece 132, and the pressing assembly 14 reset the movement along the first direction X.

[0103] Among them, the fixed part 1311, the moving part 1312 and the elastic arm 1313 are arranged in the key space 107.

[0104] In some embodiments, please refer to Figure 3 and Figure 8 , and in conjunction with other figures. The fixed part 1311 is arranged around the outer periphery of the moving part 1312, and the elastic arm 1313 is connected between the fixed part 1311 and the moving part 1312.

[0105] In this way, the moving part 1312 can stably move along the first direction X to trigger the switch piece 12 or reset.

[0106] In some embodiments, please refer to Figure 3 and Figure 8 , and in conjunction with other figures. The number of elastic arms 1313 is multiple, and the multiple elastic arms 1313 are arranged between the fixed part 1311 and the moving part 1312, so as to improve the resetting capability of the moving part 1312 when the pressing operation of the pressing piece 143 is removed.

[0107] Please refer to Figures 1 to 3, and in combination with other drawings. The power supply device provided by the embodiment of the application comprises a key structure 10, a battery module 20 and a control assembly 30. The battery module 20 is arranged in the shell assembly 11, the control assembly 30 is arranged in the shell assembly 11, the control assembly 30 is electrically connected to the battery module 20, and the switch piece 12 is arranged on the control assembly 30. Wherein, the key structure 10 in the embodiment is the same as the key structure 10 in each of the above embodiments, and specific reference can be made to the related description of the key structure 10 in each of the above embodiments, which will not be described here.

[0108] It can be understood that the switch piece 12 is arranged on the control assembly 30 and is electrically connected to the control assembly 30.

[0109] The control assembly 30 refers to an assembly structure for controlling the battery module 20 to supply power.

[0110] It should be noted that the user presses the pressing piece 143 to drive the magnetic attraction assembly 13 to move along the first direction X towards the switch piece 12 under the driving of the pressing assembly 14, so as to trigger the switch piece 12. After the switch piece 12 is triggered, the control assembly 30 controls the battery module 20 to supply power to the atomization assembly according to the triggering information of the switch piece 12, so that the atomization assembly performs atomization work.

[0111] The power supply device provided by the embodiment of the application can reduce the risk of the first magnetic attraction piece 142 falling off from the fixed piece 141 by using the key structure 10 related in each of the above embodiments.

[0112] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 6 , and in combination with other drawings. The control assembly 30 comprises a first circuit board assembly 31, a display screen 32 and a conductive connecting piece 33. The first circuit board assembly 31 is arranged in the shell assembly 11, and the first circuit board assembly 31 is electrically connected to the battery module 20. The display screen 32 is arranged on the shell assembly 11. The conductive connecting piece 33 is a flexible structure. The conductive connecting piece 33 is connected between the display screen 32 and the first circuit board assembly 31, and the switch piece 12 is arranged on the conductive connecting piece 33.

[0113] The first circuit board assembly 31 refers to an assembly structure comprising a circuit board, which is used to control the display screen 32 and the battery module 20.

[0114] The display screen 32 can be a touch display screen 32 or a non-touch display screen 32.

[0115] The conductive connecting piece 33 is a flexible structure, that is, the conductive connecting piece 33 is a flexible flat cable.

[0116] The conductive connecting piece 33 is connected between the display screen 32 and the first circuit board assembly 31, and is located between the display screen 32 and the first circuit board assembly 31. The conductive connecting piece 33 is connected to the display screen 32 and the first circuit board assembly. Specifically, the conductive connecting piece 33 is electrically connected to the display screen 32, and the conductive connecting piece 33 is electrically connected to the first circuit board assembly, so that the display screen 32 and the first circuit board assembly 31 are electrically connected.

[0117] The switch piece 12 is arranged on the conductive connecting piece 33, so that the switch piece 12 is electrically connected to the conductive connecting piece 33, and the switch piece 12 is electrically connected to the first circuit board assembly 31.

[0118] The conductive connecting piece 33 is a flexible structure, so that the arrangement of the conductive connecting piece 33 in the shell assembly 11 is very flexible. The switch piece 12 is arranged on the conductive connecting piece 33 which is a flexible structure, so that the arrangement of the switch piece 12 is also very flexible, so that the switch piece 12, the magnetic attraction assembly 13 and the pressing assembly 14 can be flexibly installed in the small key space 107. In this way, the shell assembly 11 can save space to arrange the battery module 20, so that the power supply capacity of the power supply device can be improved.

[0119] It should be noted that the first conductive terminal 311 is arranged on the first circuit board assembly 31. When the atomization assembly is installed on the power supply device, specifically when the atomization assembly is installed on the shell assembly 11, the first conductive terminal 311 on the first circuit board assembly 31 is connected to the atomization assembly in a conductive manner, so that the first circuit board assembly 31 and the atomization assembly are electrically connected.

[0120] The first conductive terminal 311 can be a conductive structure such as a spring needle or a spring sheet.

[0121] It should be noted that the user presses the pressing piece 143 to drive the magnetic attraction assembly 13 to move along the first direction X towards the switch piece 12 under the driving of the pressing assembly 14, so as to trigger the switch piece 12. After the switch piece 12 is triggered, the first circuit board assembly 31 controls the battery module 20 to supply power to the atomization assembly according to the trigger information of the switch piece 12, so that the atomization assembly performs atomization work.

[0122] In some embodiments, please refer to Figure 3 and Figure 9 , and in combination with other drawings. Among them, Figure 9 is a perspective view of the display screen 32, the conductive connecting piece 33 and the reinforcing piece 60 of the power supply device provided by some embodiments of the present application. The switch piece 12 is arranged on one side of the conductive connecting piece 33 along the first direction X, and the other side of the conductive connecting piece 33 away from the switch piece 12 along the first direction X is provided with the reinforcing piece 60.

[0123] The reinforcing member 60 can be, but is not limited to, a plate structure. The reinforcing member 60 can be a metal structure, a plastic structure, or the like.

[0124] By arranging the reinforcing member 60 on the side of the conductive connecting member 33 away from the switch piece 12 along the first direction X, the reinforcing member 60 can support the conductive connecting member 33, thereby maintaining the position stability of the switch piece 12 along the first direction X. In this way, when the user presses the pressing piece 143 to drive the magnetic attraction assembly 13 to move along the first direction X towards the switch piece 12 under the driving of the pressing assembly 14, the switch piece 12 will not move along the first direction X under the pushing of the magnetic attraction assembly 13 due to the support of the reinforcing member 60, thereby enabling the magnetic attraction assembly 13 to stably trigger the switch piece 12.

[0125] In some embodiments, please refer to Figure 3 , Figures 9 to 11 , and in combination with other drawings. Among them, Figure 10 is a partial perspective view of a power supply device provided by some embodiments of the present application, Figure 11 is a perspective view of a mounting bracket 112 of a power supply device provided by some embodiments of the present application. The housing assembly 11 is provided with a second limiting groove 103, the switch piece 12 is arranged on the side of the conductive connecting member 33 along the first direction X, and the conductive connecting member 33 is provided with a third protruding part 331 on the side away from the switch piece 12 along the first direction X. The third protruding part 331 is limited in the second limiting groove 103 along the second direction Y and is limited in the second limiting groove 103 along the third direction Z. Among them, the first direction X and the second direction Y are perpendicular, the first direction X and the third direction Z are perpendicular, and the second direction Y and the third direction Z intersect.

[0126] It can be understood that the second limiting groove 103 is located in the key space 107.

[0127] It can be understood that the third protruding part 331 is inserted into the second limiting groove 103 along the first direction X and is limited in the second limiting groove 103 along the second direction Y and the third direction Z. In this way, the position stability of the conductive connecting member 33 in the housing assembly 11 is improved, thereby improving the position stability of the switch piece 12 in the key space 107, which facilitates the stable triggering of the switch piece 12 by the magnetic attraction assembly 13.

[0128] The second direction Y and the third direction Z intersect, which means that the third direction Z and the second direction Y can form an included angle greater than 0° and less than 180°, that is, the third direction Z and the second direction Y are not parallel. The third direction Z and the second direction Y can be perpendicular to each other or not. The third direction Z and the second direction Y can be directions intersecting on the same plane, or directions on planes respectively perpendicular to each other, and the projection of the second direction Y on the plane where the first direction X is located can intersect the third direction Z. As an example, the second direction Y and the third direction Z are perpendicular.

[0129] As an example, the first direction X can be the width direction of the aerosol generating device, the second direction Y can be the height direction of the aerosol generating device, and the third direction Z can be the thickness direction of the aerosol generating device.

The first circuit board assembly 31 is arranged on one side of the battery module 20 along the second direction Y. In the second direction Y, the pressing member 143 is arranged between the display screen 32 and the first circuit board assembly 31. The first direction X and the second direction Y are perpendicular.

[0132] It can be understood that the battery module 20 and the first circuit board assembly 31 are distributed along the second direction Y, and the battery module 20 and the display screen 32 are distributed along the first direction X. The key space 107 is located on the side of the battery module 20 along the first direction X with the display screen 32, and is located on the side of the display screen 32 along the second direction Y close to the first circuit board assembly 31. In this way, the switch member 12, the magnetic attraction assembly 13 and the pressing assembly 14 occupy less space inside the shell assembly 11, so that the shell assembly 11 can save more space to arrange the battery module 20, thereby improving the power of the power supply device.

[0133] In some embodiments, please refer to Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figures 10 to 12 , and in combination with other drawings. Among them, Figure 12A perspective view of the housing assembly 11 and the locking structure 40 of the power supply device provided for some embodiments of the present application is shown. The housing assembly 11 can include a housing 111 and a mounting bracket 112, which is arranged in the housing 111.

The electrically conductive connecting member 33 is arranged on the mounting bracket 112, the magnetic attraction assembly 13 is arranged on the mounting bracket 112, and the through hole 102 is arranged on the housing 111. The mounting bracket 112 and the housing 111 form a key space 107.

[0134] In the first direction X, the mounting cavities 104 are arranged along the display screen 32, and in the second direction Y, the mounting cavities 104 are arranged along the first circuit board assembly 31. In the first direction X, the key space 107 is arranged on the side of the mounting cavities 104 where the display screen 32 is located. In the second direction Y, the key space 107 is arranged on the side of the display screen 32 close to the first circuit board assembly 31.

[0135] Specifically, the mounting bracket 112 includes a first bracket body 1121 and a second bracket body 1122, both of which are arranged in the housing 111. The first bracket body 1121 is arranged on one side of the battery module 20 in the first direction X, and the second bracket body 1122 is arranged on one side of the battery module 20 in the second direction Y. The housing 111, the first bracket body 1121, and the second bracket body 1122 form the mounting cavity 104, and the first bracket body 1121 and the housing 111 form the key space 107. The display screen 32 is arranged on the side of the first bracket body 1121 away from the battery module 20 in the first direction X, the switch member 12 is arranged on the side of the first bracket body 1121 away from the battery module 20 in the first direction X, and the first circuit board assembly 31 is arranged on the second bracket body 1122.

[0136] In some embodiments, please refer to Figure 3 and Figure 12 , and in combination with other drawings. The housing assembly 11 has a mounting cavity 104 for mounting the battery module 20. When the battery module 20 is located in the mounting cavity 104, the battery module 20 and the first circuit assembly are in electrical connection.

[0137] It can be understood that the first circuit board assembly 31 has a second electrically conductive terminal 312. When the battery module 20 is located in the mounting cavity 104, the second electrically conductive terminal 312 and the battery module 20 are in electrical connection, so that the first circuit board assembly 31 and the battery module 20 are electrically connected.

[0138] The second electrically conductive terminal 312 can be a spring, a spring needle, or other electrically conductive structure.

[0139] In some embodiments, please refer to Figure 3 and Figure 12 , and in combination with other drawings. The power supply device further comprises a locking structure 40 and an elastic structure 50. The locking structure 40 is rotatably connected to the shell assembly 11 and can be rotated to a first position or a second position. The locking structure 40 is clamped to the battery module 20 when in the first position, so as to limit the battery module 20 in the installation cavity 104. The locking structure 40 is disengaged from the battery module 20 when in the second position, so as to allow the battery module 20 to be taken out of the installation cavity 104. The elastic structure 50 is connected to the locking structure 40 and the shell assembly 11, and is used to provide an elastic force to the locking structure 40 to keep it in the first position.

[0140] The installation cavity 104 refers to a cavity in the shell assembly 11 for installing the battery module 20. Specifically, the installation cavity 104 is provided with an opening 105 for the battery module 20 to enter and exit the installation cavity 104. It can be understood that the battery module 20 can enter the installation cavity 104 from the opening 105, and can also be taken out of the installation cavity 104 through the opening 105.

[0141] The locking structure 40 refers to a structure for limiting the battery module 20. The locking structure 40 can be rotated to a first position or a second position, which means that the locking structure 40 has a first position and a second position, and when the locking structure 40 is rotated relative to the shell assembly 11, it can be rotated to the first position or the second position.

[0142] Specifically, when the battery module 20 is located in the installation cavity 104 and the locking structure 40 is in the first position, the locking structure 40 is clamped with the battery module 20, so that the battery module 20 is limited in the installation cavity 104 under the limiting action of the locking structure 40. At this time, the battery module 20 cannot be taken out of the installation cavity 104.

[0143] Specifically, when the locking structure 40 is in the second position, the locking structure 40 is disengaged from the battery module 20, that is, the clamping action between the locking structure 40 and the battery module 20 is removed. At this time, the battery module 20 is not limited by the locking structure 40, so that the battery module 20 can be taken out of the installation cavity 104.

[0144] The elastic structure 50 refers to a structure with elastic properties. Among them, the elastic structure 50 can be a spring, a spring piece, a tension spring, etc.

[0145] The elastic structure 50 is used to provide an elastic force to the locking structure 40 to keep it in the first position, which means that the elastic structure 50 is used to provide an elastic force to the locking structure 40, so that the locking structure 40 is kept in the first position under the action of the elastic force of the elastic structure 50. In this way, the locking structure 40 and the battery module 20 maintain a clamped relationship, so that the battery module 20 is limited in the installation cavity 104.

[0146] The locking structure 40 is rotationally connected to the housing assembly 11 and can be rotated to a first position or a second position, and the locking structure 40 is disengaged from the battery module 20 when in the second position, so that the locking structure 40 can be rotated to the second position relative to the housing assembly 11 under the action of an external force to disengage the locking structure 40 from the battery module 20, thereby removing the locking effect of the locking structure 40 on the battery module 20. In this way, the user can remove the locking effect of the locking structure 40 on the battery module 20 by applying an external force to the locking structure 40, so that the battery module 20 can be removed from the mounting cavity 104, thus making the disassembly and assembly of the battery module 20 very simple and convenient.

[0147] It should be noted that when the battery module 20 is not located in the mounting cavity 104, the locking structure 40 is in the first position under the elastic action of the elastic structure 50. During the process of installing the battery module 20 into the mounting cavity 104, the locking structure 40 can be pressed by the battery module 20 to rotate to the second position. When the battery module 20 is moved into position in the mounting cavity 104, the locking structure 40 is again rotated to the first position under the elastic action of the elastic structure 50, so that the battery module 20 is limited in the mounting cavity 104 under the limiting action of the locking structure 40. Based on this, the operation of installing the battery module 20 into the mounting cavity 104 is very simple, and no external force needs to be applied to the locking structure 40.

[0148] In some embodiments, please refer to Figure 3 and Figure 12 together with other drawings. The opening 105 is provided at one end of the housing assembly 11 away from the first circuit board assembly 31 in the second direction Y.

[0149] In some embodiments, please refer to Figure 3 , Figures 12 to 15 together with other drawings. Among them, Figure 13 is a perspective view of the locking structure 40 of the power supply device provided in some embodiments of the present application. Figure 14 is Figure 2 an enlarged view of D in FIG. 8, Figure 15 is Figure 6 an enlarged view of E in FIG. 8. The battery module 20 is provided with a third limiting groove 201 on the side close to the switch piece 12 in the first direction X, and the third limiting groove 201 is provided with a first groove wall 202 away from the opening 105 in the second direction Y. The locking structure 40 includes a pivoting portion 41, a pressing portion 42 and a clamping portion 43. The pivoting portion 41 is rotationally connected to the housing assembly 11. The pressing portion 42 is provided on the pivoting portion 41 and at least partially exposed on the side of the housing assembly 11 away from the mounting cavity 104 in the first direction X. The clamping portion 43 is provided on the pivoting portion 41.

[0150] It can be understood that the pivot portion 41, the pressing portion 42 and the clamping portion 43 can be synchronously rotated relative to the shell assembly 11.

[0151] When the lock catch structure 40 is in the first position, the clamping portion 43 abuts against the first slot wall 202, so that the clamping portion 43 is clamped in the third limiting slot 201. At this time, the battery module 20 cannot be pulled out of the opening 105 along the second direction Y under the abutting action of the clamping portion 43. When the lock catch structure 40 is in the second position, the clamping portion 43 is located on the side of the first slot wall 202 away from the mounting cavity 104 along the first direction X, so that the clamping portion 43 is separated from the first slot wall 202, and the lock catch structure 40 does not limit the battery module 20. At this time, the battery module 20 can be pulled out of the opening 105 along the second direction Y.

[0152] In this way, by pressing the pressing portion 42, the pressing portion 42, the pivot portion 41 and the clamping portion 43 can be synchronously rotated, so that the lock catch structure 40 is rotated from the first position to the second position, and thus the battery module 20 can be pulled out of the mounting cavity 104.

[0153] In some embodiments, please refer to Figure 3 , Figures 12 to 15 , and other drawings. The elastic structure 50 is abutted between the shell assembly 11 and the pressing portion 42.

[0154] Specifically, the pivot portion 41 is rotationally connected to the first frame body 1121, and the pivot portion 41 and the pressing portion 42 are both arranged on the side of the first frame body 1121 away from the mounting cavity 104 along the first direction X. The first frame body 1121 is provided with a through slot 106 along the first direction X, and at least part of the clamping portion 43 is arranged in the through slot, so that the clamping portion 43 can be clamped in the third limiting slot 201.

[0155] Specifically, the conductive connecting piece 33 is arranged on the side of the first frame body 1121 away from the mounting cavity 104 along the first direction X, and specifically, the second limiting slot 103 is arranged on the side of the first frame body 1121 away from the mounting cavity 104 along the first direction X. The first frame body 1121 and the shell 111 surround to form a key space 107.

[0156] The first circuit board assembly 31 is arranged on the second frame body 1122.

[0157] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 6 and Figure 14 , and other drawings. The battery module 20 is provided with a charging interface 24.

[0158] In this way, the battery module 20 can be charged independently. Thus, the battery module 20 can be charged through the charging interface 24 when the battery module 20 is located in the installation cavity 104, or the battery module 20 can be charged through the charging interface 24 after the battery module 20 is removed from the installation cavity 104.

[0159] It can be understood that the battery module 20 includes a battery shell 21, a battery 22, a second circuit board assembly 23, and a charging interface 24. The battery 22 is arranged in the battery shell 21, the second circuit board assembly 23 is arranged in the battery shell 21, and the second circuit board assembly 23 is electrically connected to the battery 22. The charging interface 24 is arranged on the battery shell 21, and the second circuit board assembly 23 is electrically connected to the charging interface 24.

[0160] When the battery module 20 is located in the installation cavity 104, the second circuit board assembly 23 and the second conductive terminal 312 are in butt joint conduction, so that the first circuit board assembly 31 and the second circuit board assembly 23 are electrically connected. In this way, the first circuit board assembly 31 and the second circuit board assembly 23 can cooperate to control the battery 22 to perform a power supply operation.

[0161] In some embodiments, the shell 111 is a transparent structure. In this way, the appearance of the power supply device can be improved.
