Therefore, only one water pump is used for pumping water to the negative pressure cavity and supplying water to the hydraulic cavity, the structure is simple and ingenious, two water pumps are not needed, and the cost of one water pump is saved. Of course, in other embodiments, the water pump and the water supply pump may be independently configured as different water pumps.
In this embodiment, the hydraulic mechanism 30 is provided in the drain valve 10, and a hydraulic chamber 31 is formed in the valve body 11. The piston 32, the control floating barrel 13 and the valve core 12 are assembled into an integrated structure, so that the control floating barrel 13 and the piston 32 are in transmission connection with the valve core 12, and the structure in the valve body 11 is simple and compact. The timing when the piston 32, the control float 13 and the valve core 12 are reset to the initial position to finish the water discharge can be selected as the timing when the water pumping mechanism stops pumping water, the timing when the water supply mechanism stops supplying water, or the timing when the water level in the water tank drops to a predetermined position. In this embodiment, the end of the water discharge is realized by specifically adopting a mode that when the water level in the water tank drops to a predetermined position, the piston 32, the control float 13 and the valve core 12 drop together and reset to an initial position.

The guide sleeve 162 is provided to allow the control float 13 to reliably and smoothly slide up and down in the valve body 11.
In this embodiment, in order to enable the water level in the water tank to fall to a predetermined position, the piston 32, the control float bucket 13 and the valve core 12 can fall and reset reliably in time to finish water drainage, the valve body 11 is further provided with a counterweight cavity 17, the counterweight float bucket 171 capable of moving up and down is arranged in the counterweight cavity 17, and when the water level falls to the predetermined water level, the counterweight float bucket 171 falls and applies a downward acting force to an integrated structure formed by the piston 32, the control float bucket 13 and the valve core 12, so that the valve core 12 can fall and close the water outlet 1111 reliably in time. Also, in some embodiments, the height of the weighted pontoon 171 may be designed to be adjustable, so that the amount of water discharged can be adjusted by adjusting the height of the weighted pontoon 171. Specifically, the counterweight float bucket 171 is provided with an abutting portion 1711, when the counterweight float bucket 171 is located at a falling position, the abutting portion 1711 is located above the top end opening of the hydraulic pressure chamber 31 or located at the top end opening or located in the hydraulic pressure chamber 31, and when the counterweight float bucket falls, the abutting portion 1711 abuts against the piston 32, so that the piston 32, the control float bucket 13 and the valve spool 12 form an integrated structure, and the integrated structure falls and returns to an initial position. As shown in fig. 3 and 5, when the weighted float 171 of the present embodiment is in the falling position, the abutting portion 1711 is located slightly above the top end opening of the hydraulic chamber 31.
In this embodiment, the top end of the control floating barrel 13 is closed, the bottom end of the control floating barrel is opened, the top wall of the control floating barrel 13 and the inner wall of the valve body 11 enclose a negative pressure cavity 14, an overflowing gap 15 is formed between the side wall of the control floating barrel 13 and the inner wall of the valve body 11, and water in the water tank flows into the negative pressure cavity 14 through the overflowing gap 15. Thus, the water flow flowing through the flow gap 15 flows from bottom to top, and can further play a role in assisting in controlling the floating of the floating barrel 13.
In this embodiment, the valve body 11 includes a base 111 and an upper valve body 112, the water outlet 1111 is disposed on the base 111, and the base 111 and the upper valve body 112 are connected to form an inner cavity for accommodating the control float bowl 13.
A water pump mounting seat 23 is further fixed to one side of the upper valve body 112 or the base 111, and the common water pump 20 is mounted on the water pump mounting seat 23.

In other embodiments, the water pump mounting seat 23 can be fixed on one side of the base 111, and the whole drainage device can be more compact and faster to install.
Preferably, in this embodiment, the overall position of the negative pressure chamber 14 is lower than the operating water level of the water tank. This makes it possible to make the negative pressure chamber 14 in a full water state in an initial state of not draining water, so that it is easier to form a sufficient negative pressure.

In the embodiment, referring to fig. 4, the water flow of the outlet 22 of the common water pump 20 is divided into two paths, one path flows to the hydraulic chamber 31, and the other path flows to the flushing water path (which may be the brush ring water path or the spraying water path of the toilet).
Referring to fig. 3 to 5, when the drainage device of the toilet is just started and the drainage port 1111 is not opened, the common water pump 20 pumps water from the negative pressure chamber 14, and a part of the water flows to the flushing waterway of the toilet, and another part of the water flows to the hydraulic chamber 31 of the hydraulic mechanism 30, and the water in the cistern is replenished into the negative pressure chamber through the overflow gap 15 and continuously pumped out of the negative pressure chamber by the water pump 20 to provide a sufficient flushing water amount to the flushing waterway of the toilet, and the curves with arrows in fig. 3, 4 and 5 show the path of the flushing water flow of the common water pump 20.
When water in the negative pressure cavity 14 is pumped out by a certain amount to form sufficient negative pressure, the floating barrel 13 is controlled to float under the combined action of the negative pressure and the self buoyancy and drives the valve core 12 to open the water outlet 1111 for water drainage. Meanwhile, referring to fig. 5, the common water pump 20 supplies water to the hydraulic chamber 31 such that the piston 32 moves upward and the piston 32 also drives the valve cartridge 12 to open the drain port 1111 to drain, i.e., controls both the float 13 and the piston 32 to act on the valve cartridge 12, and drives the valve cartridge 12 upward together.
Referring to fig. 6, at this time, when the water level in the tank drops to a predetermined water level, the counterweight float tub 171 drops, and the counterweight float tub 171 abuts against the piston 32 through the abutting portion 1711 so that the integrated structure composed of the piston 32, the control float tub 13, and the valve element 12 drops and returns to the initial position, so that the valve element 12 closes the water outlet 11 in time to finish water drainage.
