[0020] The present utility model will be further described below in conjunction with the attached drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0021] The present utility model provides a control button with a waterproof function as shown in Figure 1-2 Figure 10, which includes a housing 1. There is a chamber 11 inside the housing 1. An inductor 12 is provided at the bottom end inside the chamber 11. A through hole 13 communicating with the chamber 11 is provided on the surface of the housing 1. A pressing rod 14 is movably connected inside the through hole 13. One end of the pressing rod 14 penetrates through the through hole 13 and extends to the outside of the housing 1 to be connected with a rubber soft sleeve 2. An installation groove 15 is provided on the surface of the housing 1 outside the through hole 13. A sealing ring 16 is provided in the installation groove 15. The bottom end of the rubber soft sleeve 2 is provided with a first sealing pressing plate 21 adapted to the installation groove 15. A second sealing pressing plate 22 is provided below the first sealing pressing plate 21. Both the first sealing pressing plate 21 and the second sealing pressing plate 22 are embedded in the installation groove 15.

[0022] A sealing groove 211 is provided at the bottom end of the first sealing pressing plate 21. A sealing protrusion 221 is provided at the top end of the second sealing pressing plate 22. The sealing protrusion 221 is snap-fitted with the sealing groove 211. By the way of snap-fitting the sealing protrusion 221 with the sealing groove 211, the tightness of the connection between the first sealing pressing plate 21 and the second sealing pressing plate 22 can be improved, and it can be avoided that rainwater flows into the rubber soft sleeve 2 through the gap between the first sealing pressing plate 21 and the second sealing pressing plate 22, which affects the service life of the device.

[0023] A waterproof groove 222 is provided at the top end of the sealing protrusion 221. A water absorption ring 223 is embedded inside the waterproof groove 222. Through the water absorption ring 223 embedded in the waterproof groove 222, the rainwater flowing into the gap between the sealing protrusion 221 and the sealing groove 211 can be absorbed, which can avoid rainwater flowing into the rubber soft sleeve 2 and affecting the service life of the device, and it is convenient to replace the water absorption ring 223, and the waterproof performance of the device is also improved.

[0024] The inner side wall of the chamber 11 is symmetrically provided with sliding grooves 18. A slider 181 is slidably connected in each sliding groove 18. One end of each slider 181 penetrates through the sliding groove 18 and extends to the outside and is fixedly connected to the side wall of the pressure rod 14. A spring 182 is connected between the bottom end of each slider 181 and the bottom end of the inner wall of the chamber 11.

[0025] A guide rod 183 is slidably penetrated through the surface of each slider 181. Both ends of the guide rod 183 are fixedly connected to the upper and lower inner walls of the chamber 11. By providing the guide rod 183, the slider 181 can move up and down more stably and smoothly.

[0026] A sealing sleeve 19 is sleeved outside the pressure rod 14. The top end of the sealing sleeve 19 is fixedly connected to the inner wall top end of the chamber 11. The inner wall of the sealing sleeve 19 is in close contact with the outer wall of the pressure rod 14. By providing the sealing sleeve 19, the connection between the housing 1 and the pressure rod 14 can be sealed and waterproofed, thereby further improving the waterproof performance of the device.

[0027] A plurality of uniformly distributed threaded holes 17 are opened on the surface of the housing 1 outside the installation groove 15. The rubber soft sleeve 2 is fixedly connected to the housing 1 by means of bolts passing through the rubber soft sleeve 2 and the threaded holes 17. By fixing the rubber soft sleeve 2 to the housing 1 by means of bolts passing through the rubber soft sleeve 2 and the threaded holes 17, the disassembly and assembly between the rubber soft sleeve 4 and the housing 1 can be facilitated, so that when the rubber soft sleeve 4 is damaged, the rubber soft sleeve 4 can be conveniently replaced.

[0028] The working principle of the present utility model:

[0029] Refer to the attached Figure 1-2 In the specification, when the button needs to be pressed, the user presses the top position of the rubber soft sleeve 4, so that the pressure rod 14 moves downward in the through hole 13 and contacts the sensor 12 to touch the sensor 12, so as to transmit an instruction. During the downward movement of the pressure rod 14, the slider 181 is driven to move downward along the guide rod 183 and compress the spring 182. After the pressing is completed, under the action of the spring 182, the slider 181 drives the pressure rod 14 to reset. In rainy days, by providing the rubber soft sleeve 4, the pressure rod 14 can be prevented from being directly exposed to the air, avoiding rainwater from entering the chamber 11 through the gap of the through hole 13 and damaging the sensor 12. And through the combined use of the first sealing pressing plate 21, the second sealing pressing plate 22 and the sealing ring 16, rainwater can be prevented from entering the rubber soft sleeve 4 through the installation groove 15, and the waterproof performance is good.

[0030] Refer to the attached Figure 1-2, when using this device, by means of the snap connection between the sealing protrusion 221 and the sealing groove 211, the tightness of the connection between the first sealing pressing plate 21 and the second sealing pressing plate 22 can be improved, and rainwater can be prevented from flowing into the rubber soft sleeve 2 through the gap between the first sealing pressing plate 21 and the second sealing pressing plate 22, which affects the service life of the device. Through the water-absorbing ring 223 embedded in the waterproof groove 222, the rainwater flowing into the gap between the sealing protrusion 221 and the sealing groove 211 can be absorbed, preventing rainwater from flowing into the rubber soft sleeve 2 and affecting the service life of the device. Moreover, it is convenient to replace the water-absorbing ring 223, which also improves the waterproof performance of the device. By providing the guide rod 183, the slider 181 can move up and down more stably and smoothly. By providing the sealing sleeve 19, the connection between the housing 1 and the pressure rod 14 can be sealed and waterproofed, further improving the waterproof performance of the device. By fixing the rubber soft sleeve 2 to the housing 1 by means of bolts passing through the rubber soft sleeve 2 and the threaded holes 17, the disassembly and assembly between the rubber soft sleeve 4 and the housing 1 can be facilitated, so that when the rubber soft sleeve 4 is damaged, it is convenient to replace the rubber soft sleeve 4.

[0031] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
