The air bag 5 will not inhale air from the water tank 4 when recovering to inhale, a push plate 6 is fixedly connected to the lower end surface of the air bag 5, the push plate 6 is slidably connected to the fixed plate 3, two return springs 7 are respectively fixedly connected between the fixed plate 3 and the push plate 6, one end of the water outlet pipe 8 is fixedly connected to the side wall of the water tank 4, and a nozzle 9 is fixedly connected to the other end of the water outlet pipe 8.

[0017] The cleaning mechanism also includes a rotating shaft 18 and a cam 19. The end of the support plate 2 away from the fixed plate 3 is fixedly connected to the slide 16, and a fixed seat is slidably connected to the slide 16. The fixed seat is fixedly connected to the motor 17. The rotating shaft 18 is fixedly connected to the output end of the motor 17. The rotating shaft 18 passes through the support plate 2. The cam 19 is fixedly connected to the outer surface of the rotating shaft 18. A turning tool head is provided at the end of the rotating shaft 18 away from the motor 17.

[0018] The side wall of the support plate 2 is rotatably connected with a threaded rod 10, and the threaded rod 10 is threadedly connected with a fixing ring 11. The side wall of the fixing ring 11 is fixedly connected with two sliding rods, and the two sliding rods are slidably connected to the support plate 2. The threaded rod 10 can be rotated to adjust the distance between the fixing ring 11 and the support plate 2. The sliding rod makes the fixing ring 11 maintain horizontal movement as a whole, and will not cause one end of the fixing ring 11 to deflect due to the movement of the threaded rod 10 on one side. The end of the fixing ring 11 away from the threaded rod 10 is fixedly connected with a plurality of push rods, and the end of the push rod away from the fixing ring 11 is fixedly connected with a slider 12, and a V-shaped plate 21 is slidably connected to the slider 12. The lower end surface of the V-shaped plate 21 is fixedly connected with a fixing block, and the nozzle 9 is fixedly connected to the fixed The lower end surface of the block and the lower end surface of the V-shaped plate 21 are fixedly connected with a clamping rod 13, and the outer surface of the clamping rod 13 is slidably connected with a circular ring plate 14. The end of the clamping rod 13 away from the V-shaped plate 21 is fixedly connected with a clamping plate 15. The distance from the nozzle 9 to the clamping plate 15 is fixed, so the nozzle 9 can accurately spray water into the inside of the valve seat. A plurality of fixing rods are fixedly connected between the circular ring plate 14 and the fixed plate 3. When the fixing ring 11 moves forward or backward horizontally, it will drive the slider 12 forward and backward to squeeze the V-shaped plate 21. At the same time, the V-shaped plate 21 is limited by the clamping rod 13 and can only rise or fall. Therefore, when the fixing ring 11 moves toward the circular ring plate 14, it will drive the slider 12 to squeeze the V-shaped plate 21. The V-shaped plate 21 is driven downward, thereby driving the clamping rod 13 and the clamping plate 15 to move closer to the center of the annular plate 14. Conversely, when the fixing ring 11 moves away from the annular plate 14, the clamping rod 13 and the clamping plate 15 are driven away from the center of the annular plate 14, so that valve seats of different diameters can be clamped, thereby improving the practicability of the device.

[0019] When in use, first place the trash can under the annular plate 14, place the valve seat in the annular plate 14, rotate the threaded rod 10 to drive the fixed ring 11 to move, and adjust it according to the size of the valve seat to make the fixed ring 11 move forward or backward, thereby pushing the slider 12 forward or backward, driving the V-shaped plate 21 and the clamping rod 13 to move up or down, and the clamping plate 15 clamps the valve seats of different diameters, and starts the slide 16 and the motor 17. The motor 17 moves forward and drives the rotating shaft 18 to rotate. The rotation of the rotating shaft 18 drives the cutter head to perform turning operations, and the rotating shaft 18 drives the cam 19 to rotate. When the cam 19 approaches the push plate 6, it squeezes the push plate 6 and the airbag 5, and the gas in the airbag 5 is squeezed into the water tank 4. When the cam 19 moves away from the push plate 6, it is reset under the action of the reset spring 7, driving the airbag 5 to stretch and inhale air from the outside, and repeatedly allowing the water in the water tank 4 to enter the nozzle 9 along the water outlet pipe 8, and be sprayed from the nozzle 9 into the valve seat, thereby cooling the inside of the valve seat and flushing the cut debris into the trash can. The distance from the nozzle 9 to the clamping plate 15 is fixed, so the distance from the valve seats of different diameters to the nozzle 9 is basically the same, and the nozzle 9 can accurately spray into the inside of the valve seat.
