In addition, the present invention can be implemented in a variety of different forms and is not limited to the embodiments described in this embodiment. The purpose of providing the following specific embodiments is to facilitate a clearer and more thorough understanding of the disclosure of the present invention, in which words indicating directions such as up, down, left, and right are only for the position of the structure shown in the corresponding drawings. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set on..." should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The following description is a preferred embodiment of the present invention, but the above description is for the purpose of illustrating the general principles of the present invention and is not intended to limit the scope of the present invention. The scope of protection of the present invention shall be determined by the appended claims.

[0027] Please also read Figure 1 and Figure 2 , Figure 1 It is a side view of the atomization device 1000 provided in an embodiment of the utility model; Figure 2 yes Figure 1 The atomizing device 1000 is a cross-sectional view along the AA line in FIG. The atomizing device 1000 includes a housing 100, an atomizing module 200, and a power supply module 300. The power supply module 300 and the atomizing module 200 are arranged in the housing 100, and the power supply module 300 can supply power to the atomizing module 200, so that the power supply module 300 atomizes the atomizing matrix in the atomizing module 200 and generates aerosol for the user to inhale.

[0028] In this embodiment, the atomization module 200 is replaceable and can be used as a disposable part of the atomization device 1000. The atomization module 200 can be used as a long-lasting part of the atomization device 1000, that is, a fixed part. Among them, the life of the power supply module 300 is generally greater than the service life of the atomization module 200. Therefore, after the atomization matrix of the atomization module 200 is used up, the atomization module 200 is removed from the housing 100 and replaced with a new atomization module 200, thereby reducing the use cost of the atomization module 200 and improving the environmental protection of the atomization module 200.

[0029] It should be noted that Figure 2 The purpose is only to schematically describe the arrangement of the housing 100, the atomization module 200 and the power supply module 300, and it is not to make specific limitations on the connection positions, connection relationships and specific structures of the various components. Figure 1 The structure of the atomizing device 1000 is only shown in the embodiment of the present invention, and does not constitute a specific limitation on the atomizing device 1000. In other embodiments of the present invention, the atomizing device 1000 may include Figure 2 More or fewer components, or a combination of certain components, or different components, such as the atomization device 1000 may also include but are not limited to a temperature sensor or a light-emitting component, etc.

[0030] For the accuracy of description, please refer to the directions in this article. Figure 1 and Figure 2 For reference, the term "length direction X" refers to the direction parallel to the pressing direction of the key 10, that is, Figure 2 The term “height direction Z” refers to the arrangement direction of the two keys 10 in the key assembly 340, that is, Figure 1 and Figure 2 The term "width direction Y" refers to the direction perpendicular to the length direction X and the height direction Z, that is, Figure 1 The longitudinal direction of the atomizing device 1000 is shown in FIG. The length direction X, the width direction Y, and the height direction Z together constitute three orthogonal directions of the atomizing device 1000. The length direction X, the width direction Y, and the height direction Z of the atomizing device 1000 can be customized according to the specific structure of the product and the viewing angle of the attached drawings, and the present utility model does not make specific limitations.

[0031] See also Figure 2 For example, in this embodiment, the power supply module 300 includes a battery case 310, a power supply battery 320, a circuit board 330 and a key assembly 340. The power supply battery 320 is installed in the battery case 310 and is electrically connected to the circuit board 330. Each key 10 in the key assembly 340 corresponds to the position of the control switch on the circuit board 330.

[0032] Please also read Figure 2 and Figure 3 , Figure 3 yes Figure 2 1 is an enlarged view of part I of the atomizing device 1000 in FIG. At least two control switches 331 are provided on the circuit board 330. The number of control switches 331 corresponds to the number of buttons 10, that is, each control switch 331 is arranged relative to the corresponding button 10. The control switch 331 is electrically connected to the control chip mounted on the circuit board 330, and the control switch 331 is generally a membrane switch. It can be understood that different pins / ports of the control chip can be activated when different control switches 331 are turned on, so that the control chip performs different functions, so the user can press different buttons 10 to make the atomizing device 1000 enter different working modes. For example, at least two buttons 10 may have but are not limited to the function of controlling the opening or closing of the atomizing device 1000, the display function of the atomizing device 1000, the power of the atomizing device 1000, the function of controlling the operation of different atomizing modules, and the unlocking and self-locking of the atomizing device 1000. It should be noted that the function of the button 10 can be set according to the actual situation, and the embodiment of the utility model is not specifically limited.

[0033] Exemplarily, the atomizer module 200 is installed in the battery sleeve 310, so that the atomizer module 200 and the power supply module 300 are integrated into one body and installed in the housing 100, thereby realizing the modular assembly of the atomizer device 1000. Of course, in some other embodiments, the atomizer module 200 and the power supply module 300 can be set independently of each other. For example, the atomizer module 200 can be set at one end of the power supply module 300, that is, the atomizer module 200 and the power supply module 300 are at Figure 1 The atomizing module 200 and the power supply module 300 are arranged in parallel in the height direction Z to achieve Figure 1 The atomizing device 1000 is stacked in the height direction Z, thereby reducing the volume of the atomizing device 1000 and making the atomizing device 1000 more compact and portable.

[0034] In one possible implementation, the atomizer module 200 is detachably connected to the battery sleeve 310, thereby facilitating operations such as maintenance and replacement of the atomizer module 200, improving usage flexibility, and enriching application scenarios. In another possible implementation, the atomizer module 200 is non-detachably connected to the battery sleeve 310, thereby improving the reliability and stability of the connection between the atomizer module 200 and the battery sleeve 310 and improving assembly efficiency.

[0035] The battery sleeve 310 is detachably connected to the housing 100. For example, the battery sleeve 310 and the housing 100 may be detachably connected together by, but not limited to, a snap structure, an adsorption structure, or a screw. For example, in this embodiment, the battery sleeve 310 and the housing 100 are detachably connected together by a snap structure. In a possible implementation, the battery sleeve 310 and the housing 100 may also be non-detachably connected together by gluing or welding.

[0036] Please also read Figure 1 and Figure 2 , the housing 100 includes a shell body 110 and a cover plate 120. The button assembly 340 is arranged between the cover plate 120 and the battery sleeve 310, and can be movably penetrated through the cover plate 120 and the battery sleeve 310, so as to realize the pressing operation of the button 10 to control the opening or closing of the control switch 331 of the circuit board 330 corresponding to the button 10. The shell body 110 and the cover plate 120 are detachably connected, so as to facilitate the assembly of the button assembly 340. The shell body 110 and the cover plate 120 can be detachably connected together by a snap-on structure, an adsorption structure or screws, etc., but not limited to. The outer wall of the cover plate 120 is smoothly connected to the outer wall of the shell body 110. For example, the outer wall of the cover plate 120 is connected and flush with the outer wall of the shell body 110, so that the atomizing device 1000 has a complete and regular outer wall, avoiding scratches on the outer wall of the atomizing device 1000.

[0037] In one possible implementation, please also refer to Figure 1 and Figure 2 The atomizing device 1000 further includes a display screen 400. The display screen 400 can be used to display visual information of the atomizing device 1000, thereby improving the user experience and visual experience. The visual information includes but is not limited to at least one of the state parameters such as atomizing parameters, power parameters, and oil quantity parameters. The display screen 400 can be but is not limited to an organic light-emitting diode (OLED) screen or a liquid crystal display (LCD) screen.

[0038] For example, in this embodiment, the display screen 400 and the button assembly 340 can be arranged on the same side of the atomizing device 1000, so as to facilitate the user's viewing and operation, and optimize the spatial layout of the display screen 400 and the button assembly 340, shorten the distance of the connection line between the circuit board 330 and the display screen 400, and improve the space utilization rate of the atomizing device 1000. More specifically, the display screen 400 and the button assembly 340 are arranged on the side wall of the housing 100 along the width direction Y. In a possible implementation, the display screen 400 and the button assembly 340 can also be arranged on different sides of the atomizing device 1000; or, the atomizing device 1000 can also omit the display screen 400, which is not specifically limited in the embodiment of the utility model.

[0039] See also Figure 2 , the button assembly 340 is applied to the power supply module 300 of the atomization device 1000. The button assembly 340 includes at least two buttons 10, an elastic arm 20 and a positioning member 30. The elastic arm 20 is connected to the at least two buttons 10 as a whole. The positioning member 30 is arranged on the elastic arm 20, and is used to position the elastic arm 20 in an area adjacent to the display area of ​​the power supply module 300 of the atomization device 1000. Specifically, the positioning member 30 fixes the elastic arm 20 on the battery sleeve 310 of the power supply module 300. Among them, the display area is the area where the atomization device 1000 can display the picture or atomization data or battery data, and the adjacent area of ​​the display area is the area close to the display area. For example, the display area can be Figure 1 In the display screen 400 shown, the adjacent area of ​​the display area may be as follows Figure 1 The area on the left side of the display screen 400 is on the same side of the atomization device 1000 as the display screen 400. In some other embodiments, the adjacent area and the display area may not be on the same side of the atomization device 1000, but may be on two adjacent or intersecting sides. The specific setting can be made according to actual needs, and the button assembly 340 can be set close to the display area.

[0040] In some embodiments, the atomization module device is not actually equipped with a display screen, but such atomization devices are often equipped with LED lights to display information. In this case, the LED lights can also be considered as the display area. The above-mentioned button assembly 340 is arranged in the vicinity of the LED. The vicinity and the display area may not be on the same surface of the atomization device 1000, but may be on two adjacent or intersecting sides. The specific arrangement can be made according to actual needs, and the button assembly 340 can be arranged close to the display area.

[0041] The button assembly 340 provided in the embodiment of the utility model is based on connecting at least two buttons 10 into a whole through an elastic arm 20, and a positioning piece 30 is provided on the elastic arm 20 for fixing the elastic arm 20 on the battery sleeve 310 of the power supply module 300. On the one hand, the number of parts of the button assembly 340 is reduced, the cost is reduced, modular assembly is achieved, and the space utilization rate of the atomization device 1000 is improved; on the other hand, the button 10 is fixed to the battery sleeve 310 through the positioning piece 30 provided on the elastic arm 20, thereby avoiding the button 10 from shaking when the atomization device 1000 moves, thereby improving the user experience.

[0042] It can be understood that the button 10 has a pressed state and a non-pressed state. Figure 2 and Figure 3 When the button 10 is subjected to an external force, the button 10 moves toward one side of the circuit board 330 under the action of the external force until the button 10 presses against the control switch 331 on the circuit board 330, so as to trigger the control switch 331 of the circuit board 330 to be turned on or off. When the button 10 is in a pressed state, the elastic arm 20 is deformed. When the external force acting on the button 10 is removed, the elastic arm 20 gradually recovers its deformation, and the button 10 moves toward the side facing away from the circuit board 330 under the action of the elastic force of the elastic arm 20, until the button 10 is separated from the contact with the control switch 331 on the circuit board 330, so as to achieve the reset of the button 10, which is convenient for the user to press the button 10 next time. When the button 10 is in a non-pressed state, the elastic arm 20 recovers its deformation.

[0043] Please also read Figure 1 , Figure 3 and Figure 4 , Figure 4 yes Figure 1 The atomization device 1000 in the structure diagram omits the cover plate 120. The button 10 is movably provided in the cover plate 120 and the battery sleeve 310. Specifically, the cover plate 120 is provided with a first movable hole 1201 at a position corresponding to the button 10, and the battery sleeve 310 is provided with a second movable hole 3101 at a position corresponding to the first movable hole 1201. The button 10 is movably provided in the first movable hole 1201 and the second movable hole 3101. Exemplarily, in the present embodiment, the button 10 is clearance-matched with the first movable hole 1201 and the second movable hole 3101, that is, a gap is formed between the button 10 and the hole wall of the first movable hole 1201 and the hole wall of the second movable hole 3101, thereby providing a movable space for the pressing operation of the button 10.

[0044] The elastic arm 20 can be movably inserted into the battery sleeve 310. Specifically, the elastic arm 20 can also be movably inserted into the second movable hole 3101, so as to realize the elastic deformation of the elastic arm 20. The radial dimension of the second movable hole 3101 is larger than the radial dimension of the first movable hole 1201, so that the elastic arm 20 can drive the button 10 to reset. The elastic arm 20 and the second movable hole 3101 are clearance-matched, that is, a gap is also formed between the elastic arm 20 and the hole wall of the second movable hole 3101, thereby providing a movable space for the deformation of the elastic arm 20.

[0045] When the button 10 is in a non-pressed state, the elastic arm 20 is suspended above the circuit board 330 in the pressing direction of the button 10, thereby providing a movable space for the elastic deformation of the elastic arm 20. In a possible implementation, when the button 10 is in a non-pressed state, the elastic arm 20 abuts against the cover plate 120, so that the elastic arm 20 and the cover plate 120 are stopped, thereby preventing the end of the elastic arm 20 facing away from the fixing portion 21 from causing the button 10 to shake. The surface of the elastic arm 20 facing away from the circuit board 330 is parallel to the surface of the cover plate 120 facing the elastic arm 20, thereby facilitating alignment and assembly.

[0046] The button 10 is protruded relative to the elastic arm 20 toward the side facing away from the circuit board 330, so as to facilitate the alignment and installation of the button 10 with the cover plate 120 and the battery sleeve 310. In the present embodiment, when the button 10 is in a non-pressed state, the button 10 is protruded relative to the cover plate 120, so as to facilitate user operation. Of course, in some other embodiments, when the button 10 is in a non-pressed state, the button 10 is located in the first movable hole 1201, that is, the end face of the button 10 facing away from the circuit board 330 can be retracted relative to the surface of the cover plate 120 facing away from the circuit board 330, or can be connected to and flush with the surface of the cover plate 120 facing away from the circuit board 330, thereby improving the aesthetics of the atomization device 1000.

[0047] For example, in this embodiment, the button assembly 340 includes two buttons 10. The two buttons 10 are arranged at intervals along the height direction Z. It should be noted that the number of the above buttons 10 is only for illustration, and the embodiment of the utility model does not make a specific limitation. For example, the button 10 can also be but not limited to one, three, four or more than four, etc.

[0048] Please also read Figure 5 and Figure 6 , Figure 5 yes Figure 1 A structural schematic diagram of a key assembly 340 of the atomization device 1000 from a first perspective; Figure 6 yes Figure 1Schematic diagram of the structure of the second perspective of the button assembly 340 of the atomization device 1000 in FIG. The button 10 includes a button cap 11 and a pressing rod 12. The pressing rod 12 is connected to the button cap 11 and is used to press the control switch 331 on the circuit board 330. The pressing rod 12 is convexly arranged at one end of the button cap 11. More specifically, the pressing rod 12 is arranged inside the button cap 11. Exemplarily, in this embodiment, the cross section of the button cap 11 along the pressing direction perpendicular to the button 10 is roughly circular, which can provide a uniform force surface for the user to press while maintaining beauty. The cross section of the pressing rod 12 along the pressing direction perpendicular to the button 10 is cross-shaped, which can provide uniform force when abutting the control switch 331. In a possible implementation, the cross section of the button cap 11 along the pressing direction perpendicular to the button 10 can also be but not limited to semicircular, elliptical, triangular or square, etc., and the cross section of the pressing rod 12 along the pressing direction perpendicular to the button 10 can also be but not limited to circular or square, etc. The cross section of the pressing rod 12 along the pressing direction perpendicular to the key 10 may also be, but not limited to, an X-shape, a V-shape, etc. It should be noted that the shape of the cross section of the button cap 11 or the pressing rod 12 along the pressing direction perpendicular to the key 10 can be designed according to actual needs, and the utility model does not make specific limitations.

[0049] In one possible implementation, see Figure 5 , a side of the button 10 close to the fixing portion 21 is provided with an avoidance notch 101. Exemplarily, in this embodiment, the avoidance notch 101 is arranged to avoid the battery sleeve 310. Thus, the arrangement of the avoidance notch 101 can shorten the distance between the two buttons 10, increase the space utilization rate of the battery sleeve 310 between the two buttons 10, thereby improving the compactness of each component of the button assembly 340, saving space, and realizing the miniaturization design of the button assembly 340. More specifically, a side of the button cap 11 close to the fixing portion 21 is provided with an avoidance notch 101 arranged to avoid the battery sleeve 310.

[0050] In a possible implementation, a limiting structure is provided on the surface of the elastic arm 20 facing away from the circuit board 330, and a matching structure matching the limiting structure is provided on the surface of the cover plate 120 facing the elastic arm 20, so as to facilitate the assembly of the elastic arm 20 and the cover plate 120, and can limit the elastic arm 20 in a plane perpendicular to the pressing direction of the button 10, thereby preventing the button 10 from shaking in a non-pressed state following the movement of the atomization device 1000. One of the limiting structure and the matching structure is a groove structure, and the other is a protrusion structure.

[0051] Please also read Figure 3 , Figure 5 and Figure 6, the elastic arm 20 includes a fixing portion 21 and at least two elastic portions 22. One end of each elastic portion 22 is connected to the fixing portion 21, and the other end of each elastic portion 22 is connected to the corresponding button 10. A positioning member 30 is provided on the fixing portion 21. Thus, on the one hand, based on the setting that one end of the elastic arm 20 is fixedly connected to the battery sleeve 310 through the fixing portion 21, the other end of the elastic arm 20 is fixedly connected to the button 10, so that the elastic arm 20 can be deformed under the pressing activity of the button 10, and the elastic force of the elastic arm 20 drives the button 10 to restore the deformation when the external force is removed; on the other hand, the button 10 is fixedly connected to the battery sleeve 310 through the fixing portion 21 of the elastic arm 20, so that the button 10 will not be displaced in the plane perpendicular to the pressing direction of the button 10, thereby avoiding the shaking of the button 10 when the atomizing device 1000 is moved, improving the user experience, and avoiding the button 10 from hitting the shell 100 and being damaged, thereby extending the service life of the button 10.

[0052] In this embodiment, the fixing portion 21 is spaced apart from the key 10, thereby avoiding interference between the key 10 and the fixing portion 21 and improving the smoothness of pressing the key 10. In a possible implementation, the fixing portion 21 and the key 10 are slidably matched, so that the fixing portion 21 can provide a guide for the pressing activity of the key 10 and avoid the key 10 from shaking.

[0053] The elastic part 22 is configured as an open loop structure. Exemplarily, in this embodiment, the elastic part 22 is bent relative to the button 10 toward the side facing away from the button 10, and forms a gap 201 with the side wall of the button 10. Thus, the length of the elastic part 22 is extended, the elastic coefficient of the elastic part 22 is increased, and the rapid reset of the button 10 is facilitated. Exemplarily, in this embodiment, the elastic part 22 includes an elastic section 221 and a connecting section 222. The elastic section 221 is connected between the connecting section 222 and the fixed part 21, and the elastic section 221 is arranged around the button 10 and forms a gap 201 with the side wall of the button 10. The connecting section 222 is bent relative to the elastic section 221 toward the side of the button 10, and is connected to the side wall of the button 10. Thus, based on the setting that the connecting section 222 is bent relative to the elastic section 221 toward the side of the button 10, the force arm of the elastic part 22 is increased, so that a small force applied to the button 10 can drive the elastic part 22 to deform, thereby improving the user experience.

[0054] In this embodiment, the gap 201 between the elastic segment 221 and the side wall of the key 10 remains unchanged from the fixing portion 21 to the connecting segment 222 along the extension direction of the elastic segment 221, thereby facilitating the processing and forming of the elastic arm 20 and improving the elastic coefficient of the elastic arm 20. In a possible implementation, the gap 201 between the elastic segment 221 and the side wall of the key 10 gradually decreases from the fixing portion 21 to the connecting segment 222 along the extension direction of the elastic segment 221. For example, the connecting segment 222 can be omitted, that is, the elastic segment 221 is directly fixedly connected to the side wall of the key 10.

[0055] The connecting section 222 is disposed close to the fixing portion 21 and spaced from the fixing portion 21, thereby avoiding interference between the key 10 and the elastic arm 20 during the pressing activity, improving the smoothness of pressing the key 10; and extending the length of the elastic arm 20, thereby improving the elastic coefficient of the elastic arm 20. The connecting section 222 is detachably fixed to the side wall of the key 10, thereby facilitating the maintenance of the key assembly 340. Of course, in some embodiments, the connecting section 222 can also be fixed to the side wall of the key 10 in a non-detachable manner.

[0056] At least two elastic parts 22 are arranged at equal intervals around the center of the fixing part 21, so that the force on each elastic part 22 is basically the same, which improves the structural strength of the elastic arm 20 and prolongs the service life. More specifically, one of the two adjacent elastic parts 22 can be obtained by rotating the other elastic part 22 by a preset angle.

[0057] The number of elastic parts 22 corresponds to the number of buttons 10 one by one, so that each button 10 can be reset by the corresponding elastic arm 20, thereby improving the compactness of the structure. By way of example, in the present embodiment, the number of elastic parts 22 is two. The two elastic parts 22 are roughly in the shape of an "8". In one possible implementation, the number of elastic parts 22 may include an even number, that is, all elastic parts 22 are arranged in pairs. The two elastic parts 22 arranged in pairs are arranged symmetrically with respect to the fixed part 21, so that when each button 10 is pressed, the force of the fixed part 21 is concentrated in the center, avoiding the situation where the connection between the fixed part 21 and the elastic part 22 breaks, and extending the service life of the button assembly 340. Of course, in another possible implementation, the number of elastic parts 22 may include an odd number, that is, all elastic parts 22 may not be arranged in pairs.

[0058] In a possible implementation, the width of the fixed portion 21 along the width direction Y of the power supply module 300 is greater than the width of the elastic portion 22 along the normal direction of the extension path of the elastic portion 22. The area of ​​the longitudinal section of the fixed portion 21 perpendicular to the width direction Y of the power supply module 300 is greater than the area of ​​the longitudinal section of the elastic portion 22 along the normal direction of the extension path of the elastic portion 22. Thus, on the one hand, the area of ​​the fixed portion 21 is increased, which is convenient for the processing and forming of the positioning member 30; on the other hand, the structural strength of the fixed portion 21 is improved, and the service life of the elastic arm 20 is extended. It should be noted that the term "extension path" refers to the trajectory of the extension direction of the elastic portion 22. The elastic portion 22 is strip-shaped. For example, under normal circumstances, for a strip-shaped object, the length direction of the strip-shaped object is the extension direction of the strip-shaped object. Among them, the normal direction refers to the direction perpendicular to the tangent direction of the extension path, that is, the tangent direction of any position point on the extension path of the elastic portion 22 is perpendicular to the normal direction.

[0059] For example, in this embodiment, the positioning member 30 is inserted into the battery sleeve 310. In a possible implementation, the orthographic projection of the positioning member 30 in the pressing direction of the key 10 is located within the orthographic projection of the fixing portion 21 in the pressing direction of the key 10, that is, the fixing portion 21 covers the positioning member 30 in the pressing direction of the key 10. On the one hand, the fixing portion 21 can stop the battery sleeve 310 to limit the depth of the positioning member 30 inserted into the battery sleeve 310, avoid the positioning member 30 from damaging the circuit board 330, and facilitate the alignment of the positioning member 30 and the battery sleeve 310; on the other hand, the edge force of the elastic portion 22 acting on the fixing portion 21 can be transmitted to the battery sleeve 310 and / or the cover plate 120, thereby avoiding the situation where the fixing portion 21 and the elastic portion 22 are broken at the connection. The positioning member 30 is arranged at the center of the fixing portion 21, thereby improving the supporting performance of the fixing portion 21 for the elastic deformation of the elastic portion 22. The center of the fixing portion 21 refers to the central part of the geometric shape of the positioning member 30. The extension lines of the extension paths of the two elastic portions 22 intersect at the center of the positioning member 30 , that is, the two elastic portions 22 are centrally symmetrically arranged relative to the center of the positioning member 30 .

[0060] For example, in this embodiment, the cross section of the fixing portion 21 along the pressing direction perpendicular to the key 10 is substantially rectangular, and the side wall of the fixing portion 21 is protruding relative to the side wall of the elastic portion 22. Of course, in some embodiments, the side wall of the fixing portion 21 and the side wall of the elastic portion 22 may also be connected and flush, thereby simplifying the processing technology of the elastic arm 20.

[0061] In a possible implementation, the side wall of the positioning member 30 is provided with an anti-rotation structure 31. The anti-rotation structure 31 is used to limit the button 10 from rotating relative to the battery sleeve 310. Thus, the button 10 is prevented from shaking when the atomizing device 1000 moves, thereby improving the user experience.

[0062] Exemplarily, in the present embodiment, the anti-rotation structure 31 is an anti-rotation surface provided on the side wall of the positioning member 30. More specifically, the positioning member 30 is configured as a prismatic structure to form an anti-rotation surface on the side wall of the positioning member 30. The cross-section of the positioning member 30 along the pressing direction perpendicular to the key 10 is square. In one possible implementation, the anti-rotation surface can be configured as a profiled surface. A profiled surface refers to an irregular, asymmetric surface. Of course, in other embodiments, the anti-rotation structure 31 can also be an anti-rotation protrusion and / or an anti-rotation groove provided on the side wall of the positioning member 30. The design of the anti-rotation structure 31 can be designed according to actual conditions, and the embodiments of the utility model are not specifically limited.

[0063] At least two of the button 10, the elastic arm 20 and the positioning member 30 may be integrally formed. Of course, in some other embodiments, at least two of the button 10, the elastic arm 20 and the positioning member 30 may be independently provided and connected together. For example, in this embodiment, the positioning member 30 is integrally formed with the elastic arm 20, and the elastic arm 20 is detachably connected to the button 10.

[0064] The key 10, the elastic arm 20 and the positioning member 30 may be made of the same material, for example, including but not limited to at least one of metal, plastic, ceramic, fiber composite material or other suitable materials. Of course, in some other embodiments, at least two of the key 10, the elastic arm 20 and the positioning member 30 may be made of different materials.
