While exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be embodied in various forms without being limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0039] With reference to Figures 1-9 , the present application provides a button device, which can include a shell 1, an inner shell assembly 2, a fixed box 3, a circuit board 4, and a control button 5, wherein:

[0040] The shell 1 is a hollow structure, for example, the shell 1 can be a square tube structure. A key through hole 101 is formed on one end surface of the shell 1, and the cross section of the key through hole 101 is adapted to the cross section shape of the control key 5. The inner shell assembly 2 is embedded in the shell 1, for example, the inner shell assembly 2 can be in sliding connection with the shell 1, so that the inner shell assembly 2 can be fixed by providing a cover plate assembly at the two openings of the shell 1. The fixing box 3 is located on the end surface of the inner shell assembly 2 close to the key through hole 101, wherein the fixing box 3 is provided with a key mounting area 301 on the end surface close to the key through hole 101, and the cross section shape of the key mounting area 301 is consistent with the cross section shape of the key through hole 101.

[0041] The cross section shape of the control key 5 can be circular and annular, etc. The number of control keys 5 can also be multiple.

[0042] The circuit board 4 is located between the inner shell assembly 2 and the fixing box 3, wherein the circuit board 4 includes a button 401, the key mounting area 301 has a button through hole, and the button 401 is embedded in the button through hole, thereby forming the assembly positioning of the fixing box 3 and the circuit board 4. The button 401 is connected in series in the control circuit on the circuit board 4, so that different functions of the air pump can be controlled by operating the button 401. The control key 5 is located on the outer surface of the shell 1 and is clamped with the button 401 through the key through hole 101. Thus, the circuit board 4 can be installed close to the key through hole 101 by embedding the inner shell assembly 2, and the key can be installed on the metal shell 1 by the fixing box 3 between the circuit board 4 and the shell 1. Thus, it is beneficial to improve the product quality of the air pump, and the product applicability and user experience of the air pump can be improved.

[0043] An alternative embodiment of the application is described with reference to Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, a positioning post 501 is provided on the end face of the control button 5 near the button 401 (also referred to as the mounting surface of the control button 401). A positioning hole 302 is provided in the button mounting area 301. The positioning post 501 and the positioning hole 302 are shaped to fit together to lock the installation position of the control button 5 relative to the fixing box 3. That is, during the assembly process of the control button 5, it is pre-positioned into the positioning hole 302 by the positioning post 501, thereby locking the current installation position of the control button 5. This facilitates precise engagement between the control button 5 and the fixing box 3, improving the assembly efficiency of the device.

[0044] In one example, a button clip 502 is also provided on the end face of the control button 5 near the button 401. A button locking hole 306 is provided on the fixing box 3 at the corresponding assembly position of the button clip 502, so that the control button 5 and the fixing box 3 can be fixed by engaging the button clip 502 with the button locking hole 306. A button boss 503 is also provided on the end face of the control button 5 near the button 401. After assembly, the button boss 503 can shorten the pressing stroke between the control button 5 and the button 401, thereby improving the pressing efficiency of the control button 5.

[0045] An optional embodiment of the invention, referring to... Figure 4 and Figure 5 As shown, the fixing box 3 is also provided with two folded edges 304, which are located on opposite sides of the fixing box 3. The folded edges 304 extend from the fixing box 3 away from the button through hole 101, so as to secure the fixing box 3 to the circuit board 4. For example, the two folded edges 304 can be provided with fixing buckles 3041, so that during the assembly of the fixing box 3 and the circuit board 4, the two folded edges 304 on the fixing box 3 are pressed towards the circuit board 4, causing the two folded edges 304 to deform relative to each other, so that the circuit board 4 contacts the fixing box 3, and the folded edges 304 return to their original shape, thus completing the fixation between the fixing box 3 and the circuit board 4 through the fixing buckles 3041.

[0046] In one example, referencing Figure 4 and Figure 5 As shown, considering that the relative positions of the fixing box 3 and the circuit board 4 are not fixed during assembly, a guide hole 404 can be opened on the circuit board 4, and a guide post 307 adapted to the shape of the guide hole 404 can be provided in the corresponding area of ​​the fixing box 3. Thus, the guide post 307 can be embedded into the guide hole 404 to lock the relative positions of the fixing box 3 and the circuit board 4.

[0047] An optional embodiment of the invention, referring to... Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, the end face of the housing 1 with the button through-hole 101 also has a display through-hole 102, and the end face of the fixing box 3 near the display through-hole 102 also has a display area 303. The circuit board 4 also includes an indicator light 402, which can be LEDs arranged in a figure-eight shape and electrically connected to the control circuit on the circuit board 4. Thus, the operation status of each button 401 can be determined by the indicator light 402. For example, when the indicator light 402 is connected in series with a button 401, the indicator light 402 does not display when the button 401 controls the corresponding control circuit to disconnect. When the button 401 controls the corresponding control circuit to close, the indicator light 402 displays. The indicator light 402 is located below the display area 303. The device may also include a display window 6, which is located on the outer surface of the housing 1 and is snapped into place by the display through-hole 102. Therefore, the current operating status of the air pump can be determined by observing the display status of the indicator light 402 through the display window 6.

[0048] An optional embodiment of the invention, referring to... Figure 4 and Figure 6 As shown, multiple connecting buckles 601 are provided on the periphery of the end face of the display window 6 near the fixing box 3, and connecting holes 311 are provided at corresponding positions on the fixing box 3. This allows for the snap-fit ​​fixing of the display window 6 and the fixing box 3. To improve the connection stability of the display window 6, the multiple connecting buckles 601 can be evenly spaced on the periphery of the display window 6. A guide rod 602 is also provided on the end face of the display window 6 near the fixing box 3, and a guide groove 309 is provided at a corresponding position on the fixing box 3. Therefore, the assembly position of the display window 6 on the fixing box 3 can be determined by the shape fit between the guide rod 602 and the guide groove 309.

[0049] An optional embodiment of the invention, referring to... Figure 4As shown, the display lamp 402 is provided with a plurality of display card holes 403 on the periphery thereof, and the display area 303 is provided with a plurality of display buckles 305 on the periphery of the end face of the display lamp 402, the number of the display buckles 305 being the same as that of the display card holes 403. The display buckles 305 are matched with the display card holes 403 to press the display area 303 against the display lamp 402. The press can be understood as the pressure contact between the display area 303 and the display lamp 402, so that the display area 303 is tightly attached to the display lamp 402 on the circuit board 4, preventing poor display effect caused by light leakage and light channeling of the display lamp 402. In an example, the device can further include a protective film 8 placed on the display area 303 of the fixed box 3, so as to protect the display lamp 402 from other dust particles and impurities, preventing the display effect of the display lamp 402 from being affected.

[0050] In an optional embodiment, referring to Figure 2 As shown, the hole wall of the display via 102 is provided with a limiting step 103 along the inner periphery of the display via 102, the display window 6 is pressed against the limiting step 103 through the display via 102, and the limiting step 103 is matched with the display window 6 to completely seal the display via 102. The press can be understood as the pressure contact between the limiting step 103 and the display window. That is, on the one hand, the limiting step 103 can control the depth of the display window 6 through the display via 102, facilitating the limiting of the display window 6; on the other hand, the limiting step 103 can form all-around wrapping around the display window 6, so as to improve the assembly airtightness of the display window 6 and the display area 303, preventing poor display effect of the display window 6. In an example, the outer surface of the display window 6 is flush with the outer surface of the shell 1. Thus, the assembly aesthetics of the display window 6 can be improved, and the display window 6 is prevented from protruding outwardly from the shell 1, preventing the display window 6 from being worn during use.

[0051] In an optional embodiment, referring to Figure 4 and Figure 9As shown, a silicone button 7 is also provided between the circuit board 4 and the fixing box 3. The silicone button 7 has a cap 701, which serves as the mounting position for the button 401. The cap 701 penetrates the button mounting area 301 and contacts the control button 5. For example, the silicone button 7, corresponding to the position of the button 401, protrudes towards the fixing box 3 to form the cap 701. The protrusion of the cap 701 serves as the mounting position for the button 401. By fitting the protrusion onto the button 401, the position of the silicone button 7 relative to the circuit board 4 is defined by the cap 701. In one example, when there are multiple buttons 401, the silicone button 7 can be a single silicone pad that fully covers all the buttons 401.

[0052] The silicone cap 701 penetrates the button mounting area 301 and contacts the control button 5. A limiting block 702 is also provided on the silicone button 7, and a limiting hole 308 corresponding to the shape of the limiting block 702 is provided on the fixing box 3. This allows the limiting block 702 to limit the position of the fixing box 3 relative to the silicone button 7. The silicone button 7 increases the pressing stroke of the control button 5, improving the pressing feel and experience.

[0053] An optional embodiment of the invention, referring to... Figure 1 and Figure 2 As shown, a plurality of heat dissipation holes 104 are provided on the side of the housing 1 adjacent to the button through hole 101, and the heat dissipation holes 104 communicate with the inner cavity of the housing 1. Therefore, the heat generated by the circuit board 4 during operation can be dissipated more quickly through the heat dissipation holes 104, improving the product performance of the device.

[0054] In one optional embodiment of the invention, an assembly groove is formed on the inner surface of the housing 1, and the assembly groove extends along the length direction of the housing 1. A guide platform 310 is also provided on the end of the fixing box 3 near the button mounting area 301 (the end of the fixing box 3 along the length direction). The guide platform 310 can slide in the assembly groove, so that during the assembly process, the fixing box 3 and the circuit board 4 can be pre-assembled on the inner shell assembly 2, and then the entire inner shell assembly 2 can be assembled into the inner cavity of the housing 1 through the guide platform 310. The assembly position of the inner shell assembly 2 can be slid through the guide platform 310, and finally the assembly of the device is completed.
