[0043] In an embodiment of the utility model, an elastic support member 300 is provided in the button structure, and a gap is provided between the pressing portion 330 of the elastic support member 300 and the trigger member 120 of the switch component 100. The gap can prevent the switch component 100 from being continuously triggered and causing functional failure, and can adapt to manufacturing and assembly errors within a certain range. At the same time, the supporting portion 320 of the elastic support member 300 can elastically support the button 200 to the limit member 700, thereby realizing the positioning of the button 200 and preventing the button 200 from shaking and affecting the hand feel experience.

[0044] An embodiment of a key structure in the utility model:

[0045] In one embodiment, please refer to Figures 1 to 3 The key structure includes a switch component 100, a key 200, an elastic support member 300 and a device housing 400, and also includes a switch mounting seat 500 for mounting the switch component 100.

[0046] Combined with Figure 2 , Figure 5 and Figure 6 It can be understood that the switch component 100 can be a touch switch, including a switch body 110 and a trigger 120. The trigger 120 is used to be pressed to change the switch state of the switch component 100. Each time the trigger 120 is pressed, the internal circuit can be turned on once. After the trigger 120 is released, the trigger 120 can be reset under the action of the elastic member in the switch body 110. The outer contour of the switch body 110 can be a rectangular parallelepiped, and a plurality of pins 130 (such as Figure 5 ), this pin is Figures 2 to 4 The number of pins 130 can be set as required. When the number of pins 130 is four, the electrical schematic diagram of the switch component 100 can refer to Figure 6 Each time the trigger member 120 is pressed, the circuit can be connected once. The trigger member 120 can be a columnar structure, the trigger member 120 protrudes from the switch body 110, and the top surface can be an oblong to form a larger operating area.

[0047] It should be noted that the above introduction to the switch component 100 is only an example. In some other embodiments, the switch component 100 may also have other structural forms.

[0048] The switch component 100 can be welded on the switch mounting base 500, which can be, for example, a circuit board. The switch mounting base 500 can be fixed on a support base 600 provided on the corresponding electronic product. The structure of the support base 600 is not limited, and can be a part of the housing of the corresponding electronic product, or a separate part assembled on the device housing 400. In a specific embodiment, please refer to Figures 2 to 4 A mounting groove may be provided on the support seat 600, and the circuit board may be embedded in the mounting groove to achieve positioning.

[0049] The button 200 is movably arranged along the pressing direction of the trigger member 120. When pressed by the operator, the button 200 can move toward the trigger member 120 and trigger the switch component 100. In some embodiments, please refer to Figures 2 to 4 The key 200 may include a key body 210 and a side flange 220 .

[0050] The key body 210 can be assembled in the key installation hole 410 provided on the corresponding device housing 400, and move under the guidance of the hole wall of the key installation hole 410. It can be understood that the shape of the key installation hole 410 can match the key body 210. The limiting member 700 can be the above-mentioned device housing 400, or it can be a limiting structure separately provided on the corresponding electronic product.

[0051] The side flange 220 may surround the button body 210, or may be disposed partially on the side of the button body 210. The side flange 220 cooperates with the stopper 700, so that the stopper 700 can prevent the button 200 from escaping from the button mounting hole 410 in a direction away from the switch component 100, and can balance the elastic supporting force of the elastic supporting member 300.

[0052] In order to prevent the button 200 from continuously triggering the switch component 100 or shaking due to an excessive gap between the button 200 and the switch component 100 , in one embodiment, an elastic support member 300 is provided between the button 200 and the switch component 100 .

[0053] The elastic support member 300 includes a base portion 310 , a support portion 320 and a pressing portion 330 . In a specific embodiment, the elastic support member 300 is integrally formed of an elastic material, for example, can be integrally formed of a silicone material, and the support portion 320 and the pressing portion 330 are connected to the base portion 310 .

[0054] In a specific embodiment, the base part 310 is fixedly disposed between the switch component 100 and the button 200, for example, it can be supported on the switch mounting seat 500, or supported on the support seat 600, or supported on both the switch mounting seat 500 and the support seat 600. Considering the positioning requirements of the elastic support member 300, a concave cavity 312 can be provided on the base part 310, and the concave cavity 312 forms an opening on the side of the base part 310 away from the button 200. The button 200 switch is embedded in the concave cavity 312 and positioned by relying on the inner side wall of the concave cavity 312, so that the base part 310 can rely on the button 200 switch to be positioned in a direction perpendicular to the up and down direction.

[0055] It should be noted that, in some other embodiments, the base portion 310 may also be fixed to other positions, such as being fixed to the device housing 400 of the corresponding electronic product, or being fixed to a corresponding supporting structure provided on the device housing 400. Furthermore, the base portion 310 may be separated from the switch component 100, for example, the base portion 310 may be formed by two plate-like bases arranged at intervals, the two plate-like bases may be arranged at intervals left and right or front and back, and there may be an interval between the switch component 100 and the two plate-like portions.

[0056] The support portion 320 is elastically supported on the side of the button 200 close to the switch component 100, and the elastic support is supported in a supporting manner that can form an elastic force. The support portion 320 can be made of an elastic material, so that it can generate an elastic force by relying on its own elastic deformation. In one embodiment, the support portion 320 includes an elastomer, and the elastomer protrudes from the side of the base portion 310 to form a cantilever structure, and the elastomer relies on its own elasticity to apply an elastic supporting force to the button 200. Specifically, the support portion 320 may include an extension portion 321 and a boss portion 322, and the boss portion 322 is protruding and arranged on the side of the extension portion 321 close to the button 200, and the extension portion 321 can rely on the cantilever structure to more easily generate elastic deformation, and the boss portion 322 can support the button 200 and can also be elastically deformed.

[0057] In order to stably support the key 200, the support parts 320 are evenly distributed on the base part 310 around the circumference of the switch component 100. The circumference of the switch component 100 is the direction around the axis of the switch component 100. This is conducive to forming a symmetrical structure to ensure the force balance of the key 200 and prevent the key 200 from tilting. When there are two support parts 320, the two support parts 320 are arranged at an interval of 180 degrees, located on the left and right sides of the base part 310, and are consistent with the long axis direction of the oval key 200, so as to ensure that the force on both sides of the long axis direction of the oval key 200 is balanced.

[0058] In some other embodiments, the support part 320 itself can also be made of a rigid material, and in this case can be connected to the base part 310 through elastic parts such as shrapnel and springs, and the elastic force is generated by the elastic parts, while the support part 320 itself only plays the role of transmitting the elastic force. In the illustrated embodiment, the elastic support member 300 is integrally formed of an elastic material, and the support part 320 can generate elastic force by its own elasticity, with a simple structure and convenient manufacturing.

[0059] Please refer to Figure 4 The pressing portion 330 is disposed between the trigger member 120 and the button 200, and can transmit the pressing force of the button 200, and is used to move under the drive of the button 200 to trigger the switch component 100. There is a gap between the pressing portion 330 and the trigger member 120, and the gap can accommodate manufacturing and assembly errors to prevent the button 200 from pressing against the switch component 100, that is, continuously triggering the switch component 100.

[0060] In one embodiment, the elastic support member 300 includes an elastic deformation portion 331 connected between the pressing portion 330 and the base portion 310, and the elastic deformation portion 331 enables the pressing portion 330 to move relative to the base portion 310 toward the switch component 100. Figure 2 and Figure 4The pressing portion 330 may protrude from the elastic deformation portion, and the protruding direction of the pressing portion 330 is toward the key 200, which helps to avoid the thickness of the elastic deformation portion 331 being too thick, thereby avoiding excessive pressing force when pressing the key 200, and making the user's pressing operation easier. The elastic deformation portion may be arranged around the support portion 320, which helps to make the left and right sides of the support portion 320 and the front and rear sides more balanced. The above-mentioned elastic connection portion may be mainly used to realize the movement of the pressing portion 330, and may also have a greater elastic force so that the pressing portion 330 can also play a partial elastic supporting role for the key 200.

[0061] In a specific embodiment, the base portion 310 has a top end surface 311, and the top end surface 311 faces the button 200; the elastic deformation portion has a bending portion 332, and the bending direction of the bending portion 332 is away from the button 200. The bending portion 332 is connected to the top end surface 311. The bending portion 332 makes the cross-section of the elastic connection portion "L"-shaped, and has a circular arc transition at the corner, which is more conducive to the deformation of the elastic deformation portion.

[0062] Before pressing the button, the supporting part 320 of the elastic supporting member 300 can apply an elastic supporting force to the button 200, pressing the button 200 against the limiting member 700 to prevent the button 200 from shaking. At the same time, there is a gap between the pressing part 330 of the elastic supporting member 300 and the triggering member 120 of the switch component 100, which can isolate the button 200 from the triggering member 120 and avoid the button 200 directly acting on the triggering member 120 due to manufacturing and assembly errors within a certain range, thereby solving the technical problem that the button 200 is easy to continuously trigger the switch component 100 or shake. When pressing the button, the elastic supporting member 300 can be elastically deformed, and the button 200 can transmit the force to the triggering member 120 through the pressing part 330 to achieve the triggering of the switch component 100, thereby ensuring the realization of the normal function of the switch component 100.

[0064] The local structure of the electronic atomization device can be referred to Figures 1 to 4 , including a device housing 400, in which an atomizing assembly, a power module and a switch component 100 are arranged, and a button 200 is mounted on the device housing 400, and the switch component 100 and the button 200 adopt the button structure of any of the above embodiments. The above atomizing assembly and the power module can adopt existing structures, which will not be described in detail here.

[0065] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
