Working principle: before the device is used, the actuating mechanism body 2 is connected with the pneumatic button, the air channel 313 and the drain pipe, the water inlet 302 is connected with the water pipe, the water outlet 303 is connected with the drain pipe, when the device is used, the pneumatic button is pressed to enable high-pressure air to enter the actuating mechanism body 2, then air in the vacuum cavity 310 is discharged into the actuating mechanism body 2 through the air channel 313 and the air flow channel 402 by the actuating mechanism body 2, then the corrugated rubber film is contracted to drive the driving block 312 to overcome the force of the first spring 311, the first valve rod 307 enters the slideway 3123 in the magnetic block 3122, and then the second valve rod 307 in the installation cavity 306 moves downwards against the force of the spring under the suction force of the magnetic block 3122, so that the valve head 308 is far away from the water pipe 304, and water flows to the drain valve through the water outlet 303; at the same time, the actuator body 2 controls the blow-down valve to open, flushing away dirt.
The screw rod 8 rotates under the action of water flow to drive the rotating plate 9 to rotate together, so that the brush hair 10 on the rotating plate 9 cleans the filter screen 7.
When the device is used, gas enters the vacuum cavity 310 through the gas flow channel 402 on the regulating 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 is pushed upwards by the spring in the mounting cavity 306 under the action of no magnetic block 3122, and the valve head 308 seals the water through pipeline 304, so that the water outlet 303 is no longer discharged; and at the same time, when no gas exists, the blow-down valve is closed again.
When the closing speed of the water passage 304 needs to be slowed down, the adjusting rod 404 is rotated anticlockwise, so that the adjusting rod 404 rotates inwards, and as the front end of the adjusting rod 404 is stepped and the diameter of one end close to the outside is the largest, the opening of the air flow channel 402 through which air flows is reduced under the cooperation of the annular gasket 403, the flow speed of the air flow is slowed down, the speed of the driving block 312 separating from the first valve rod 305 is slowed down, and the closing time of the water passage 304 is delayed; when the adjusting lever 404 rotates clockwise, the adjusting lever 404 rotates outwards, the opening of the air flow channel 402 through which the air flow passes becomes larger, the speed of the driving block 312 separating from the first valve rod 305 becomes faster, and the closing speed of the water passage 304 becomes faster.
The above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. within the design concept of the present invention should be included in the scope of the present invention.
