The working principle is as follows: before the device is used, the actuator body 2 is connected with the pneumatic button, the air channel 313 and the sewage discharge pipe, the water inlet 302 is connected with the water pipe, the water outlet 303 is connected with the sewage discharge pipe, when the device is used, the pneumatic button is pressed to enable high-pressure air to enter the actuator body 2, then the air in the vacuum cavity 310 is discharged into the actuator body 2 through the air channel 313 and the air flow channel 402 through the actuator body 2, then the corrugated rubber membrane contracts to drive the driving block 312 to overcome the force of the first spring 311, so that the first valve rod 307 enters the slide channel 3123 in the magnetic block 3122, then under the suction force of the magnetic block 3122, the second valve rod 307 in the mounting cavity 306 is moved downwards to overcome the acting force of the spring, so that the valve head 308 is far away from the water pipeline 304, and water flows to the sewage discharge valve through the water outlet 303; meanwhile, the actuator body 2 controls the opening of the sewage draining valve to flush away the dirt.

Under the action of water flow, the screw rod 8 rotates to drive the rotating plate 9 to rotate together, so that the bristles 10 on the rotating plate 9 clean the filter screen 7.

After the device is used up, gas enters the vacuum cavity 310 through the gas flow channel 402 on the adjusting valve seat 401, meanwhile, the first spring 311 rebounds, the driving block 312 moves downwards under the action of elastic force, so that the magnetic block 3122 is separated from the first valve rod 305, the second valve rod 307 does not have the action force of the magnetic block 3122, the spring in the mounting cavity 306 pushes the second valve rod 307 upwards, so that the valve head 308 seals the water pipeline 304, and water does not flow out from the water outlet 303 any more; and when no gas exists, the blowdown valve is closed again.

When the closing speed of the water pipeline 304 needs to be reduced, the adjusting rod 404 is rotated anticlockwise, so that the adjusting rod 404 rotates inwards, and because the front end of the adjusting rod 404 is in a step shape and the diameter of one end close to the outside is the largest, the opening for air to flow through in the air flow channel 402 is reduced under the matching of the annular gasket 403, the flow rate of the air flow is reduced, the speed of the driving block 312 separating from the first valve rod 305 is reduced, and the closing time of the water pipeline 304 is delayed; when the adjustment lever 404 is rotated clockwise, the adjustment lever 404 is rotated outward, the opening for allowing the air flow to pass through in the air flow path 402 becomes large, the speed of the driving block 312 separating from the first valve stem 305 becomes fast, and the closing speed of the water passage 304 becomes fast.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the design concept of the present invention should be included in the scope of the present invention.
