[0041] Below, some implementation modes of the present application will be described in detail in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0042] In the present application, the connection structure of the position of the key assembly is improved to avoid the situation of abnormal noise or shaking of the keys, making the keys stable and having good performance.

[0043] Please refer to Figures 1 to 3As shown, in some embodiments, a key assembly 130 is provided. The key assembly 130 mainly includes a key 131, a microswitch 133, and an elastic connecting member 132. One end of the microswitch 133 is arranged towards the key 131; the elastic connecting member 132 abuts against the key 131, and the elastic connecting member 132 is arranged between the key 131 and the microswitch 133. The above key assembly 130 is only one embodiment of the present application, and the specific connection structure of the key assembly 130 will not be elaborated here. Exemplarily, the key 131 and the elastic connecting member 132 can adopt an interference connection method.

[0044] In some embodiments, the microswitch 133 is an electronic switch, which is used to close or disconnect a circuit by a small physical touch, has the characteristic of fast response, and is suitable for high-frequency operations; the elastic connecting member 132 needs to have a certain elastic deformation amount, and can cause the elastic connecting member 132 to undergo elastic deformation and abut against the microswitch 133, so as to facilitate triggering the microswitch 133. When the key 131 is pressed, the elastic connecting member 132 abuts against the microswitch 133, so that the key 131 triggers the microswitch 133 through the elastic connecting member 132.

[0045] Therefore, the key 131 can trigger the microswitch 133 through the elastic connecting member 132. The elastic connecting member 132 can play a buffering role for the key 131, and the structure is simple. Thus, pressing the key 131 can achieve the purpose of triggering the microswitch 133. After pressing, the key 131 can be reset under the action of the elastic connecting member 132. The elastic connecting member 132 can have a reaction force on the key 131, maintain a constant displacement amount of the key 131, and make reasonable use of the internal space.

[0046] In some embodiments, as Figure 1 and Figure 2 shown, the elastic connecting member 132 can define an installation cavity 134, and the microswitch 133 is arranged in the installation cavity 134. Correspondingly, the installation cavity 134 is used to place the microswitch 133, limit the microswitch 133, reduce the situation of misalignment or offset of the microswitch 133, and further make the position of the microswitch 133 correspond to the position of the key 131, improve the sensitivity of the key assembly 130, and the key 131 drives the elastic connecting member 132 to deform and then trigger the microswitch 133.

[0047] Furthermore, in combination with Figure 2 and Figure 3As shown, the elastic connecting member 132 includes a fixing portion 1322 and an elastic portion 1323. The fixing portion 1322 is snap-connected to the microswitch 133. One side of the elastic portion 1323 abuts against the button 131. There is a gap between the elastic portion 1323 and the microswitch 133. When the elastic portion 1323 undergoes elastic deformation, the button 131 reaches the purpose of triggering the microswitch 133 through the elastic portion 1323. When the button 131 is pressed, the side of the elastic portion 1323 away from the button 131 can abut against the microswitch 133 to trigger the microswitch 133. In addition, after the button 131 is released, the elastic portion 1323 will gradually return to its original position, so that there is a gap between the elastic portion 1323 and the microswitch 133, completing a process of triggering the microswitch 133. The elastic portion 1323 needs to have a certain elasticity. The fixing portion 1322 may not have elasticity. Of course, the elastic portion 1323 and the fixing portion 1322 may also be integrally provided, that is, the fixing portion 1322 may also have a certain elasticity. Exemplarily, the material of the elastic portion 1323 is one of silicone, polyurethane, TPU (Thermoplastic Polyurethane), TPE (Thermoplastic Elastomer), and latex.

[0048] This application does not specifically limit the shape of the button 131, which can be regular shapes such as a runway shape, a circular shape, a square shape, a diamond shape, or other irregular shapes, as long as it has a pressing portion for the user to press. Of course, the button 131 can also integrate a capacitance detection function for detecting and receiving the user's pressing.

[0049] Exemplarily, the elastic portion 1323 is connected to the fixing portion 1322 and forms an installation groove 1321. The installation groove 1321 of the elastic connecting member 132 and the circuit board 120 can define an installation cavity 134 for placing the microswitch 133.

[0050] In addition, as Figure 3 shown, a card slot 1322a is provided on one side of the fixing portion 1322. The microswitch 133 is snap-connected to the card slot 1322a of the fixing portion 1322 to facilitate the positioning of the microswitch 133.

[0051] Refer to Figure 4 and Figure 5As shown, the power supply device 100 has a first direction X, a second direction Z, and a third direction Y. Taking the length direction of the power supply device 100 as an example for the first direction X, the height direction of the power supply device 100 as an example for the second direction Z, and the width direction of the power supply device 100 as an example for the third direction Y, wherein the first direction X, the second direction Z, and the third direction Y are perpendicular to each other pairwise. It can be understood that the above definitions are only for facilitating the understanding of the relative position relationship of the power supply device 100 and should not be construed as a limitation to this application.

[0052] In some embodiments, referring to Figure 2 and Figure 5 As shown, engaging portions 1311 are provided at both opposite ends of the button 131 along the first direction X. The engaging portions 1311 are used for installing and limiting the button 131, thereby improving the stability of the button 131. Further, the number of the engaging portions 1311 is at least two, that is, the two engaging portions 1311 are arranged along the length direction of the button assembly 130, reducing the occurrence of the situation where the button 131 shakes and improving the stability of the button 131. Of course, the number of the engaging portions 1311 can be multiple, and the multiple engaging portions 1311 are respectively located in the circumferential direction of the button 131.

[0053] Exemplarily, the button 131 further includes a triggering portion 1312, and the triggering portion 1312 is arranged facing the elastic portion 1323 of the elastic connecting member 132. When the button 131 is pressed, the button 131 abuts against the elastic portion 1323 of the elastic connecting member 132 through the triggering portion 1312, and further achieves the purpose that the triggering portion 1312 triggers the micro switch 133 through the elastic portion 1323.

[0054] Please refer to Figure 4 and Figure 5As shown, in some embodiments, a power supply device 100 is further provided. The power supply device 100 includes the button assembly 130, the housing assembly 110, and the circuit board 120 in any of the above embodiments. The housing assembly 110 includes a housing 111 and a cover 112. The housing 111 is provided with an opening, and the cover 112 covers the opening and defines a receiving cavity 113. The cover 112 is detachably connected to the housing 111, facilitating the installation of the cover 112 at the opening position of the housing 111 or the removal of the cover 112 from the housing 111, so as to facilitate the inspection and replacement of other components in the receiving cavity 113. The circuit board 120 is disposed in the receiving cavity 113. A button assembly 130 is disposed on one side of the circuit board 120. The micro switch 133 is disposed on one side of the circuit board 120, and the end of the micro switch 133 away from the circuit board 120 faces the elastic connection member 132. The housing assembly 110 and the cover 112 define the receiving cavity 113, and the circuit board 120 is installed in the receiving cavity 113. The atomizing device is controlled by the button 131 installed on the housing assembly 110, that is, the button 131 triggers the micro switch 133 to achieve the purpose of controlling the circuit board 120, and the circuit board 120 can control the functions of the atomizing device. Exemplarily, the button 131 triggers the micro switch 133 to control the power supply device 100 to supply power to the heating component of the atomizing device, without the need to activate the heating component according to the detection of suction, improving the user's suction experience. The above power supply device 100 is only one embodiment of the present application, and the remaining specific structures inside the power supply device 100 will not be elaborated herein.

[0055] Exemplarily, a snap structure is formed between the housing 111 and the cover 112. As Figure 9 and Figure 10 shown, further, the housing 111 includes a first housing 1111 and a second housing 1112. The first housing 1111 is provided with the opening and the mounting hole 1111a, and the second housing 1112 is connected to the first housing 1111, and the second housing 1112 is a semi-surrounding structure.

[0056] The power supply device 100 can be a disposable product or a cartridge replacement type product. For the cartridge replacement type, the housing assembly 110 is a detachable structure, so as to facilitate the replacement of each component in the receiving cavity 113.

[0057] In some embodiments, referring to Figure 8 and Figure 9As shown, the housing 111 is provided with a mounting hole 1111a which communicates with the accommodation cavity 113. The button 131 is inserted through the mounting hole 1111a, and the clamping portion of the button is movably clamped with the hole wall of the mounting hole 1111a. The button 131 is movably and firmly clamped with the housing assembly 110. Under the combined action of the elastic connecting member 132 and the housing assembly 110, the button 131 is limited and fixed, avoiding the situation of abnormal noise or shaking of the button 131, making the button 131 stable and having good performance, and improving the user experience. When the button 131 is clamped with the hole wall of the mounting hole 1111a, there is no gap in the position of the button 131, improving the aesthetics of the button assembly 130. The shape and size of the mounting hole 1111a are adapted to the shape and size of the button 131, and the specifications of the mounting hole 1111a are not specifically limited.

[0058] In this embodiment, as Figure 5 and Figure 6 shown, when the button 131 moves along the second direction Z, the clamping portion 1311 can be separated from the hole wall of the mounting hole 1111a. The second direction Z is perpendicular to the first direction X, that is, by pressing the button 131, the button 131 can move along the height direction of the power supply device 100, so that the clamping portion 1311 of the button 131 is separated from the hole wall of the mounting hole 1111a. Exemplarily, the number of the button assemblies 130 can be one or more. In this application, the number of the button assemblies 130 is not specifically limited and is within the protection scope of this application.

[0059] In some embodiments, referring to Figures 7 to 9 shown, the cover 112 and the housing 111 cooperate to form a mounting track 114. The circuit board 120 is movably assembled in the mounting track 114, that is, the circuit board 120 can be inserted into the housing 111 through the mounting track 114, and then the cover 112 is installed on the housing 111. The mounting track 114 plays a role in fixing and limiting the circuit board 120. Therefore, the circuit board 120 can also be removed from the mounting track 114. Further, both the cover 112 and the housing 111 are provided with limiting protrusions 1143, and the mounting track 114 is formed between the two spaced limiting protrusions 1143. Furthermore, the position of the circuit board 120 is limited by the limiting protrusions 1143. The assembly method of the circuit board 120 is relatively simple and convenient to operate.

[0060] Exemplarily, one end of the circuit board 120 abuts against the cover 112 along the first direction X, and the end of the circuit board 120 away from the cover 112 abuts against the housing 111. When the cover 112 is connected to the housing 111, both the cover 112 and the housing 111 can fix and limit the opposite ends of the circuit board 120. The circuit board 120 can be inserted into or removed from the mounting rail 114 along the first direction X, preventing the position of the circuit board 120 from shifting or being misaligned, without the need to use a snap structure or a bolt structure to fix the circuit board 120.

[0061] In this embodiment, referring to Figure 9 As shown, the mounting rail 114 includes a first mounting rail 1141 and a second mounting rail 1142. The first mounting rail 1141 and the second mounting rail 1142 are arranged side by side along the third direction Y, and the third direction Y is perpendicular to the first direction X. That is, the first mounting rail 1141 and the second mounting rail 1142 are arranged side by side along the width direction of the power supply device 100. Both the first mounting rail 1141 and the second mounting rail 1142 are used to fix and limit the circuit board 120, having a better limiting effect. Further, the first mounting rail 1141 and the second mounting rail 1142 are arranged in parallel.

[0062] In some embodiments, the present application further provides an atomization device (not shown in the figure), including the power supply device 100 and an atomizer (not shown in the figure) in any of the above embodiments. The power supply device 100 is detachably or fixedly connected to the atomizer. The power supply device 100 is used to supply power to the atomizer, and the atomizer is used to heat the atomization matrix into an aerosol. The atomization device can be a disposable product or a cartridge replacement product. For a disposable atomization device, the atomizer is fixedly connected to the power supply device 100; for a cartridge replacement atomization device, the atomizer and the power supply device 100 are detachably connected, and the atomizer and the power supply device 100 can be replaced according to the usage situation. Of course, the atomization device including the power supply device 100 has all the beneficial effects of the power supply device 100, which will not be described in detail here.

[0063] In all the examples shown and described here, any specific value should be construed as merely exemplary, not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0064] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application.
