[0037] Reference Figures 1 to 7 The present invention provides a waterproof switch 100 .

[0038] In the embodiment of the present invention, the waterproof switch 100 is applied to the installation plane 200, wherein the "installation plane 200" can be understood as a wall, a desktop or other surface of an object on which the waterproof switch 100 needs to be installed. The waterproof switch 100 specifically includes a mounting base 10, the mounting base 10 and the mounting plane 200 are detachably connected, and are formed with a water guide groove 10a, a through hole 10b and a drainage hole 10c. The through hole 10b passes through the upper and lower surfaces of the mounting base 10, and the water guide groove 10a is arranged around the outside of the through hole 10b. The drainage hole 10c is connected to the water guide groove 10a; the micro-trigger 20 is detachably connected to the mounting plane 200 and is arranged on one side of the mounting base 10; the push seat 30 is slidably connected to the mounting base 10 and is provided with a trigger column 32 and a guide horizontal surface 31a. The trigger column 32 is passed through the through hole 10b and can abut against the micro-trigger 20. The guide horizontal surface 31a and the side wall of the water guide groove 10a form a diversion gap 30a connected to the water guide groove 10a.

[0039] Specifically, in this embodiment, the mounting base 10 can be made of metal through machining or plastic through integral injection molding. The lower portion of the mounting base 10 is formed with external threads, and the mounting surface 200 is provided with a mounting hole 200a. The mounting hole 200a is provided with internal threads. The lower portion of the mounting base 10 is screwed into the mounting hole 200a and fixedly connected to the mounting surface 200. The mounting base 10 and the mounting surface 200 are fixed by threads, which has a simple structure and is relatively easy to assemble and disassemble. Of course, the mounting base 10 and the mounting surface 200 can also be connected and fixed by a snap or screw structure, which is not specifically limited here. The mounting base 10 is generally cylindrical in shape, with a through hole 10b formed in the middle thereof extending through its upper and lower surfaces. A water guide groove 10a is formed outside the through hole 10b. The water guide groove 10a is arranged around the outside of the through hole 10b and extends in an annular shape. The bottom wall of the water guide groove 10a is provided with a drainage hole 10c that communicates with the water guide groove 10a.

[0040] The micro-trigger 20 and the mounting surface 200 are removably connected to one side of the mounting base 10 via screws. The trigger base 30 includes a base 31 and a trigger column 32 connected to the base 31. The base 31 also extends in a cylindrical shape. The trigger column 32 slidably passes through the through-hole 10b, slidably connecting the base 31 to the mounting base 10. The trigger column 32 and the mounting base 10 are coaxially arranged. Under the action of external forces, the base 31 can slide back and forth relative to the mounting base 10, and the trigger column 32 can repeatedly abut the micro-trigger 20. The operating principle of the micro-trigger 20 is relatively mature technology and will not be described in detail here. The upper surface of the base 31 is the guide water surface 31a. The guide water surface 31a extends into the water channel 10a and forms a flow-guiding gap 30a connected to the sidewalls of the water channel 10a.

[0041] In the present application, operating the push-button base 30 causes the trigger cylinder 32 to slide back and forth relative to the mounting base 10, thereby reciprocatingly triggering the micro-trigger 20. External water can be guided and drained by the guide surface 31a, flowing through the guide gap 30a into the water guide groove 10a, and then out through the drainage hole 10c. This largely prevents water from flowing into the interior of the waterproof switch 100 through the through hole 10b and affecting the electrical connection between the micro-trigger 20 and other electronic components. Furthermore, since water in the water guide groove 10a can flow out through the through hole 10b or evaporate, it also prevents water from accumulating inside the waterproof switch 100 to a certain extent, thereby improving the waterproof performance of the waterproof switch 100.

[0042] Please see again Figure 4 and Figure 7 Furthermore, in this embodiment, the mounting base 10 is integrally formed with an isolation flange 11. When the mounting base 10 is connected to the mounting surface 200, the isolation flange 11 surrounds the outer side of the mounting hole 200a and abuts the mounting surface 200. The isolation flange 11 separates a portion of the lower surface of the mounting base 10 from the mounting surface 200, forming a drainage gap 11a between the mounting base 10 and the mounting surface 200. The drainage gap 11a is connected to the drainage hole 10c and can promptly guide water discharged from the drainage hole 10c to the outside, thereby preventing water from accumulating in the water channel 10a.

[0043] Furthermore, in this embodiment, the push-button base 30 includes a water-retaining flange 33 integrally formed with the base body 31. This water-retaining flange 33 is disposed around the outside of the mounting base 10 and partially extends into the water channel 10a. In this application, the provision of this water-retaining flange 33 prevents water from flowing into the through-hole 10b after the water level in the water channel 10a rises, thereby affecting the circuit connection of the micro-trigger 20. This improves the waterproof performance of the waterproof switch 100.

[0044] In one embodiment of the present invention, the waterproof switch 100 further includes a water-blocking ring 40, which can be made of an elastic silicone rubber material. Preferably, the material of the water-blocking ring 40 is self-lubricating silicone, and a snap-in groove (not shown) is formed on the outer side of the mounting seat 10. The water-blocking ring 40 is elastically snapped into the snap-in groove, and the water-blocking ring 40 can fit the side wall surface of the water-retaining flange 33. In the present application, by providing the water-blocking ring 40, water can be prevented from entering the through hole 10b through the gap between the water-retaining flange 33 and the mounting seat 10, thereby further improving the waterproof performance of the waterproof switch 100. At the same time, the water-blocking ring 40 provided with the self-lubricating silicone can make the user feel smoother when operating the pressing seat 30.

[0045] Please refer to Figure 4 and Figure 5 It is understandable that since a water-blocking ring 40 is provided between the water-blocking flange 33 and the mounting seat 10, and there is a certain friction between the two, in order to prevent the seat body 31 from being unable to reset after the micro-trigger 20 is pressed and to ensure the hand feeling of pressing, in this embodiment, a side of the water-blocking flange 33 facing the mounting seat 10 is recessed to form a position-avoiding groove 33a, and in the vertical direction, the position-avoiding groove 33a can avoid the water-blocking ring 40. The seat body 31 and the mounting seat 10 have a trigger position and a closed position, that is, in the trigger position. Figure 5 In the trigger position, the trigger column 32 abuts against the micro-trigger 20 and triggers it. At this time, the water stop ring 40 is accommodated in the avoidance groove 33a. Therefore, during the reset process, there is no force between the water retaining flange 33 and the water stop ring 40, and the seat body 31 can be reset relatively smoothly. Figure 4 In the closed position, the trigger column 32 is away from the micro-trigger 20. At this time, the water stop 40 is in contact with the side wall of the water retaining flange 33, sealing the gap between the water retaining flange 33 and the base 31. By providing the avoidance groove 33a, the present application can avoid the water stop 40 within a certain range. While ensuring waterproof performance, the waterproof switch 100 has a better operating feel and higher stability.

[0046] Furthermore, the waterproof switch 100 also includes a return spring 50. A mounting groove 10d connected to the through hole 10b is opened on the side of the mounting base 10 facing the base body 31. The return spring 50 is accommodated in the mounting groove 10d and is sleeved on the outside of the trigger column 32. The return spring 50 elastically abuts against the base body 31 and the bottom wall of the mounting groove 10d. Under the elastic force of the return spring 50, the base body 31 has a tendency to move toward the side away from the mounting base 10. This ensures that when the user presses the base body 31 downward, the base body 31 can return to its initial position normally.

[0047] Please see again Figure 2 and Figure 6In this embodiment, the push seat 30 also includes a plurality of limit buckles 34, which are arranged at intervals along the circumference of the mounting seat 10. The side wall of the water guide groove 10a is convex to form a limit flange 12. Under normal conditions, the plurality of limit buckles 34 can abut against the limit flange 12 to limit and fix the seat body 31 and the mounting seat 10 in the vertical direction.

[0048] In this embodiment, the water guide surface 31a extends in an arc shape, that is, the upper portion of the base 31 is hemispherical. This effectively guides water from the water guide surface 31a to the water guide groove 10a. Furthermore, the arc-shaped extension of the water guide surface 31a provides a better tactile feel, further enhancing the user experience of the waterproof switch 100.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
