The piston 22 is movably assembled in the hydraulic cavity 201 and connected with the water stopping assembly 24, so that the piston 22 can drive the water stopping assembly 24 to move synchronously, and the elastic resetting piece 23 acts on the piston 22; as shown in fig. 4, in a natural state, the piston 22 is driven by the elastic restoring member 23 to close the water discharge opening 203, and the water stop assembly 24 is made to close the water discharge opening 203. The output end of the water pump 10 is connected with the hydraulic water inlet 202, the hydraulic water outlet is connected with a brush ring pipe 25, and the brush ring pipe 25 is connected with a brush ring pipeline of the toilet.
The piston 22 moves against the elastic force of the elastic reset piece 23 under the action of the water pressure output by the water pump 10 to open the hydraulic water outlet, and drives the water stopping assembly 24 to open the water outlet 203. That is, when the water pump 10 operates, as shown in fig. 3, the water in the water tank is pumped into the hydraulic drain valve 20, so as to drive the piston 22 to move (move upwards in this embodiment) against the elastic force of the elastic restoring member 23 to open the hydraulic water outlet, and drive the water stopping assembly 24 to move upwards to open the water outlet 203; at the moment, the water in the water tank is discharged from the water outlet 203 to realize jet flushing, and the water pumped by the water pump 10 flows into a brush ring pipeline of the closestool through the brush ring pipe 25 to realize brush ring flushing; so, realize that single water pump 10 drives simultaneously and sprays to wash and brush the circle and wash, with reduce cost under the circumstances of guaranteeing the operation, and simple structure possesses good popularization nature.
As shown in fig. 4, when the water pump 10 loses its function, the piston 22 is reset by the elastic reset piece 23 to close the hydraulic water outlet, and drives the water stop assembly 24 to close the water outlet 203. When the water pump 10 stops running, the piston 22 loses the water pressure effect output by the water pump 10, the elastic resetting piece 23 drives the piston 22 to reset and move downwards to close the hydraulic water outlet again, and meanwhile, the water stopping assembly 24 moves downwards to close the water outlet 203; thereby stopping the flushing.
The embodiment also provides a closestool, which comprises a closestool seat, a water tank and a drainage system arranged in the water tank, wherein the drainage system is the drainage system for the closestool; the water outlet 203 of the hydraulic drain valve 20 is connected with an injection pipeline of a toilet seat, and the brush ring pipe 25 is connected with a brush ring pipeline of the toilet seat; in this manner, the drive control of the single water pump 10 described above is realized.
