Of course, in other embodiments, the elastic member 14 may not be provided, and the valve element 12 falls back only under its own weight, so that the valve element 12 can be reset.

The following is the working process of this embodiment:

referring to fig. 5, the hydraulic drain is now in an undrained state. The water inlet float 62 of the water inlet mechanism 60 is in a floating position and closes the pressure release hole 613 of the water inlet control valve 61, the water inlet control valve 61 is in a closed state, and the diaphragm 611 of the water inlet control valve 61 closes the valve port 51 on the water supply channel 50 to stop water supply to the water tank. The water stop float bowl 42 of the water stop mechanism 40 is in the float position and opens the relief hole 413 of the water stop control valve 41, the water stop control valve 41 is in the open state, and the diaphragm 411 of the water stop control valve 41 opens the valve port 31 on the through flow passage 30, but at this time the water pump 20 is not turned on, so even if the water stop control valve 41 is in the open state, the through flow passage 30 is not supplied with water to the hydraulic pressure chamber 131 of the hydraulic pressure mechanism 13, and the valve body 12 is in the falling position without being lifted by the piston 132 to close the water discharge port 111.

Referring to fig. 3, at this time, the water pump 20 is just started, the water pump 20 pumps water to the through channel 30, and since the through channel 30 is in an open state at this time, water can enter the hydraulic chamber 131 of the hydraulic mechanism 13 through the through channel 30, the piston 132 moves upward under the pressure of the water and drives the valve element 12 to move upward, so that the water outlet 111 is opened for water drainage. At the same time, a part of the water in the through channel 30 will flow to the toilet through the diversion opening 32 to flush the toilet.

Referring to fig. 4, at this time, the water level in the water tank drops to a position where the float water stopping barrel 42 falls due to insufficient buoyancy, and after the float water stopping barrel 42 falls, the pressure relief hole 413 of the water stopping control valve 41 is controlled to be closed, so that the diaphragm 411 of the water stopping control valve 41 closes the valve port 31 on the through flow channel 30 under the action of the water pressure difference (i.e., the water stopping control valve 41 is in a closed state), thereby cutting off the through flow channel 30, so that the through flow channel 30 cannot continue to supply water to the hydraulic pressure chamber 131, and then the water in the hydraulic pressure chamber 131 is discharged, and the elastic force of the elastic member 14 drives the piston 132 and the valve core 12 to return, thereby closing the water discharge port 111 and ending the water discharge. At the same time, the float 62 also drops with the water level of the tank, thereby opening the pressure release hole 613 of the inlet control valve 61 through the screw 63 and the lift lever 64 of the inlet mechanism 60, so that the diaphragm 611 of the inlet control valve 61 opens the water supply passage 50 to replenish the tank with water.

The present invention further provides a toilet (not shown), which comprises a plurality of flushing water channels, and a hydraulic drainage device according to any one of the above embodiments, wherein the water outlet 111 of the drainage valve 10 is communicated with one of the flushing water channels (e.g., the flushing water channel leading to the jet hole at the bottom of the toilet bowl of the toilet).
