Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The utility model is further described below in conjunction with embodiments.

[0032] Example: Reference Figure 1-Figure 3 The controller housing waterproof structure includes a housing 1, and further includes: a first waterproof component 2 is fixedly installed inside the housing 1, a second waterproof component 4 is contacted and connected directly below the first waterproof component 2, a plurality of water outlets 13 are opened at the bottom of the second waterproof component 4, a plurality of water suction pipes 6 are fixedly connected to one side of the plurality of water outlets 13, an air bag 11 is connected to one end of the plurality of water suction pipes 6 away from the water outlet 13, a water outlet pipe 7 is fixedly connected to one side of the air bag 11, and it is worth noting that the water suction pipe 6 and the water outlet pipe 7 are elastic rubber The material can be deformed, and one end of the water outlet pipe 7 away from the airbag 11 is fixedly connected to the water storage box 10. It is worth noting that a one-way valve is provided at one end of the water outlet pipe 7, and only water can enter the water storage box 10. A first cavity 15 is provided inside the first waterproof component 2, and a circular groove 16 is provided on the bottom wall of the first cavity 15. The movable column 14 slides in the circular groove 16, and a water retaining surface 17 is provided between the guide surface 18 and the movable column 14. The inner wall of the circular groove 16 is in contact with the water retaining surface 17, and a pressing surface 21 is provided at the bottom of the movable column 14.

[0033] Among them, a first waterproof component 2 is arranged on the equipment. When water enters the gap, the water enters the first cavity 15 of the first waterproof component 2. Since the water retaining surface 17 is in contact and connected with the bottom of the circular groove 16, when the control button 3 is not pressed, the water will be in the circular groove 16 and the first cavity 15. When the control button 3 is pressed, the bottom surface of the circular groove 16 is separated from the water retaining surface 17, and the water enters the second cavity 19 along the guide surface 18. When the control button 3 is pressed, the airbag 11 is squeezed by the pressing surface 21, and the gas in the airbag 11 is discharged through the water suction pipe 6, and negative pressure is generated in the airbag 11. When the control button 3 is released, the airbag 11 discharges the water discharged into the second cavity 19 into the water storage box 10.

[0034] Specifically, Figure 2 As shown, a limit ring 20 is fixedly installed on the bottom surface of the first waterproof component 2. The limit ring 20 prevents water from overflowing from the second cavity 19. It is worth noting that there is a sealing ring on the limit ring 20 to prevent water from leaking onto the circuit board 9.

A movable column 14 is fixedly installed on the second waterproof component 4, and a control button 3 is fixedly installed on the end of the movable column 14 away from the pressing surface 21. A guide surface 18 is set between the movable column 14 and the second waterproof component 4.

[0036] The guide surface 18 is provided so that water can quickly flow into the second cavity 19 when the control button 3 is pressed, thereby preventing some water from remaining in the first cavity 15 when the control button 3 is released.

[0037] Specifically, Figure 2 and Figure 3 As shown, the pressing surface 21 is in contact with the top surface of the airbag 11. When the control button 3 is pressed, the pressing surface 21 can press the airbag 11.

[0038] Specifically, Figure 3 As shown, a push button 8 is fixedly connected to the bottom surface of the airbag 11, and the push button 8 can be pressed after the airbag 11 discharges gas.

[0039] One end of the push button 8 away from the airbag 11 is electrically connected to a circuit board 9 , and the circuit board 9 is fixedly installed in the housing 1 .

[0040] refer to Figure 3 The water storage box 10 is slidably installed at the bottom of the shell 1. The water storage box 10 can be slidably removed to pour out the water therein. A plurality of spring rods 5 are fixedly installed on the bottom surface of the second waterproof component 4 in order to rebound and reset the control button 3 after pressing the control button 3.
