[0028] Example:

[0029] like Figures 1-4 As shown, in this embodiment, the key structure 100 includes: a shell 1, a pressing member 2, an elastic member 3 and a key plate 4; the shell 1, the side wall of the shell 1 is provided with an assembly opening 11 set along the first direction, and the shell 1 is also provided with a mounting portion 12; the pressing member 2 is assembled at the assembly opening 11; the key plate 4 is inserted into the mounting portion 12 along a second direction perpendicular to the first direction, and the key plate 4 is provided with a trigger member 41 on the side facing the pressing member 2 along the first direction; and, the elastic member 3 is arranged between the pressing member 2 and the key plate 4; wherein, the elastic member 3 includes a base 31 with an avoidance opening 311 and an elastic arm 32 connected to the base 31 and located outside the avoidance opening 311, the end of the elastic arm 32 away from the base 31 elastically abuts against the pressing member 2, and the trigger member 41 is passed through the avoidance opening 311.

[0030] Specifically, the pressing piece 2 and the elastic piece 3 form an avoiding space communicated to the avoiding port 311; the side of the key plate 4 facing the pressing piece 2 is provided with a trigger piece 41, and the end of the trigger piece 41 away from the key plate 4 penetrates through the avoiding port 311, and the pressing piece 2 and the trigger piece 41 are spaced apart from each other in the natural state. The elastic piece 3 can buffer, rebound and support the pressing piece 2 and the trigger piece 41. The trigger piece 41 can be a patch switch. The elastic piece 3 is connected between the pressing piece 2 and the key plate 4, and the elastic force direction of the elastic piece 3 is parallel to the pressing direction (the first direction) of the pressing piece 2, so that the pressing piece 2 can automatically return to the original position after being pressed by the user. The user operates the pressing piece 2 to make it contact with the trigger piece 41, so that the switch circuit of the key structure 100 is turned on, that is, the control of the switch is closed. The avoiding port 311 is arranged on the elastic piece 3, and the trigger piece 41 penetrates through the avoiding port 311, which not only ensures the rebound effect of pressing, but also saves the installation space. The avoiding port 311 and the trigger piece 41 can be assembled in an interference fit, which is simple to assemble and has good structural connection stability. As shown in Figure 1 and 2 The shell 1 is provided with a mounting portion 12 for plug-in cooperation with the key plate 4, and has good structural connection stability. During the assembly of the key structure 100, the pressing piece 2 can be first assembled into the assembly port 11 of the shell 1, then the trigger piece 41 and the elastic piece 3 are fixed, and then the key plate 4 is inserted into the mounting portion 12 in the shell 1, which is simple and convenient, and does not need to be fixed between the pressing piece 2, the trigger piece 41 and the elastic piece 3 in advance, and can be continuously operated by the system equipment to quickly complete the assembly, which is conducive to improving the production efficiency.

[0031] In the embodiment, as shown in Figure 2 The mounting portion 12 is located on the side of the shell 1 opposite to the assembly port 11 in the first direction, and is provided with an assembly space having a plug-in port formed in the second direction, and the key plate 4 and the elastic piece 3 are plug-in assembled in the assembly space through the plug-in port; so that the two ends of the key plate 4 and the side of the key plate 4 away from the assembly port 11 respectively abut against the inner wall of the mounting portion, thereby stabilizing the position of the key plate 4.

[0032] In the embodiment, the elastic piece 3 can be a silica gel piece, and the hardness of the elastic piece 3 can be set to 50°-60°. The continuous life test results show that the key structure 100 prepared in this way has good rebound, structural stability and can maintain good hand feeling for a long time. The elastic piece 3 and the key plate 4 can also be connected and reinforced by an adhesive piece, for example, the elastic piece 3 can be fixed on the key plate 4 by double-sided adhesive, so as to improve the installation stability of the elastic piece 3.

[0033] Further, as shown in Figure 1 and 3 In the embodiment, the elastic member 3 comprises a base 31 and a resilient arm 32 connected to the outer periphery of the base 31, the end of the resilient arm 32 away from the base 31 elastically abuts against the pressing member 2, the avoiding opening 311 penetrates through the base 31, and the avoiding space is formed between the base 31, the resilient arm 32 and the pressing member 2. The end of the resilient arm 32 away from the base 31 is provided with an abutting surface 321 for elastically abutting against the pressing member 2. Specifically, the pressing member 2 and the resilient arm 32 can be connected in the mode of interference connection; the interference amount can be set to 0.1mm-0.3mm, preferably 0.3mm, so that the two abutting surfaces are not in contact or the resilient arm 32 provides a small supporting force to the pressing member 2 due to the material and assembly tolerance, thereby avoiding the pressing member 2 from shaking in the shell 1 and generating abnormal sound; the interference amount of 0.2mm can ensure that the two abutting surfaces are in sufficient contact and that the resilient arm 32 can provide a large supporting force to the pressing member 2. The avoiding opening 311 is connected to the trigger member 41 in the mode of interference connection, and the interference amount can be 0.1mm-0.2mm, so that the elastic member 3 can be preliminarily positioned by the trigger member 41 during assembly.

[0034] In some embodiments, in the first direction, the side of the pressing member 2 facing the elastic member 3 is a contact plane, the contact plane abuts against the resilient arm 32, and the side of the trigger member 41 facing the pressing member 2 protrudes from the avoiding opening 311, so that the structure of the pressing member 2 is simplified, and a protruding structure is not needed to touch the trigger member 41 through the avoiding opening 311, and the stability of the contact between the pressing member 2 and the resilient arm 32 can be improved by the elastic abutment between the contact plane and the resilient arm 32.

[0035] In the embodiment, the cross-sectional area of the end of the resilient arm 32 close to the base 31 is larger than that of the end of the resilient arm 32 away from the base 31. Specifically, the cross-sectional area of the resilient arm 32 can gradually decrease from the end close to the base 31 to the end away from the base 31; the cross-sectional area of the end of the resilient arm 32 close to the base 31 is large, so that the strength of the resilient arm 32 is large and the resilient arm 32 is not easy to deform, thereby improving the structural stability of the resilient arm 32; the cross-sectional area of the end of the resilient arm 32 away from the base 31 is small, so that the flexibility of the resilient arm 32 is good, thereby improving the operation feeling of the user.

[0036] In the embodiment, the elastic arms 32 extend outwardly and obliquely relative to the base 31, that is, the elastic arms 32 extend outwardly and obliquely away from the avoiding opening 311 on the side of the base 31 facing the pressing member 2, which can reduce the size of the key structure 100 in the longitudinal direction (the pressing direction) while ensuring that the elastic arms 32 have a rebounding effect on the pressing member 2. Further, the oblique angle of the elastic arms 32 can be set to 20°-50°, the oblique angle referring to the included angle between the length extension direction of the elastic arms 32 and the transverse direction perpendicular to the pressing direction. It should be understood that the free ends (the ends away from the base 31) of the elastic arms 32 can extend outwardly and obliquely at a single oblique angle or at different oblique angles at different longitudinal positions (to form curved elastic arms 32), which is not limited herein. Preferably, the oblique angles corresponding to the positions of the elastic arms 32 gradually decrease from the end close to the base 31 to the end close to the pressing member 2.

[0037] In the embodiment, the base 31 is connected with the elastic arms 32 on opposite sides of the outer periphery of the avoiding opening 311, thereby providing a stable balancing force for the pressing member 2, avoiding the offset of the pressing member 2, and improving the stability of the key triggering. Of course, in some other embodiments, more elastic arms 32 can be arranged at intervals, so that the elastic arms 32 are uniformly distributed around the base 31, which is not limited herein.

[0038] Further, in the embodiment, the end of the base 31 facing the pressing member 2 is provided with a reinforcing rib 33, and the reinforcing rib 33 is also connected to the side of the end of the elastic arm connected to the base 31 close to the avoiding opening 311. In the natural state, the distance from the reinforcing rib 33 to the pressing member 2 is greater than or equal to the distance from the triggering member 41 to the pressing member 2, which ensures that the pressing stroke of the pressing member 2 is not affected. Specifically, the reinforcing rib 33 can include an interference portion 331 and an elastic portion 332, the interference portion 331 and the elastic portion 332 are connected around and enclose a part of the avoiding opening 311, and the elastic portion 332 is also connected to the elastic arm 32 and the base 31, which ensures that the elastic member 3 has sufficient structural strength as a whole, is conducive to increasing the elasticity of the elastic arm 32, and is also conducive to reducing the length of the elastic arm 32 in the pressing direction and reducing the installation space; that is, while ensuring that the key structure 100 has excellent performance, the key structure 100 can be made more exquisite and compact; the interference portion 331 is located on the two sides adjacent to the elastic arm 32, and is used to contact and cooperate with the outer periphery of the end of the pressing member 2 close to the triggering member 41, thereby improving the stability of the key signal triggering. In some specific embodiments, the base 31, the elastic arm 32, and the reinforcing rib 33 can be obtained by an integral molding processing method, that is, the elastic member 3 is an integral structure.

[0039] As Figure 1 and 4As shown, in the embodiment, the outer periphery of the pressing piece 2 is connected with a limiting edge 21, and the side of the limiting edge 21 away from the key plate 4 is in abutment with the inner wall of the shell 1. The cross-sectional shape of the outer surface of the limiting edge 21 can be a reverse C angle, which can play a guiding role in assembling the trigger piece 41. The limiting edge 21 and the pressing piece 2 are provided with inward abutment forces by the inner wall surface of the shell 1 at the assembly opening 11, and the pressing piece 2 is provided with outward elastic abutment forces by the elastic arm 32, so as to ensure that the pressing piece 2 can produce elastic action and contact with the trigger piece 41, and also ensure the stability of the pressing piece 2 at the assembly opening 11. The pressing piece 2 in the embodiment can be a metal key or a hardware, and can also be a plastic piece, which is not limited here.

[0040] In the embodiment, the power supply device includes the power source 200 and the key structure 100, the power source 200 is electrically connected to the key plate 4 of the key structure 100, and the power source 200 can be detachably or non-detachably installed in the shell 1, so that the key structure 100 can be powered by the power source 200 to realize the on-off control of the key structure 100.

[0041] In the embodiment, the electronic atomization device includes the atomizer 300 and the power supply device, the atomizer 300 and the power supply device are electrically connected, the power supply device can supply power to the electronic atomizer 300 and control the operation of the electronic atomizer 300; the atomizer 300 is also fixed on the shell 1, and the shell 1 is provided with a suction nozzle communicating with the atomization channel of the atomizer 300, so that the aerosol generated after the atomization medium is heated and atomized by the atomizer 300 can be discharged to the outside of the shell 1 along the atomization channel and the suction nozzle for the user to experience.
