[0039] Specifically, the valve body shell 1 top is provided with a top cover 104, the pressure relief hole 105 is opened on the top cover 104 and communicates with the valve body shell 1, the sealing member 3 includes: a swing cover and a sealing rubber nail 301 protruding on the lower end surface of the swing cover, the swing cover is provided with a hinge column 302 on both sides and is hingedly connected with the top cover 104, the rear end of the swing cover is provided with a force arm, the float 4 is arranged on the adjusting screw 5, and the upper end of the adjusting screw 5 is hingedly connected with the force arm of the swing cover.

[0040] Specifically, the water pump flushing valve of the present application is installed in the built-in water tank of the intelligent toilet, and is fixed on the wall of the water tank by the four-part nut 9. Specifically, the height of the water pump 6 can be adjusted so that the water suction port is as close as possible to the bottom of the water tank, and the direction of the water pump 6 can also be adjusted. When adjusted to the appropriate position, the water pump 6 and the valve body shell 1 are locked by the locking nut.

[0041] Specifically, the flushing ring outlet 102 is connected with the flushing ring nozzle of the toilet by a hose, and the flushing water outlet 101 is connected with the flushing water nozzle of the toilet by a hose.

[0042] Specifically, the water pump 6 is connected with a control circuit, the water tank of the toilet is provided with a water inlet valve, and the external tap water enters the water tank through the water inlet valve. When the water tank is filled with water, the pressure relief hole 105 is blocked by the sealing rubber nail 301, the air in the piston body 2 cannot be released, and the piston body 2 cannot move upward. Since the water baffle 8 only blocks the flushing water outlet 101 and does not block the flushing ring outlet 102 at the beginning, the water from the water pump 6 can only enter the flushing ring outlet 102 and flush the flushing ring of the toilet. As the water in the water tank is continuously pumped into the valve body shell 1 by the water pump 6, the water level in the water tank decreases. At this time, the float 4 falls down, the swing cover is swung upward by the adjusting screw 5, the sealing rubber nail 301 is pulled out of the pressure relief hole 105, the pressure relief hole 105 is opened, the air pressure at the top of the valve body shell 1 decreases, and the piston body 2 is driven upward by the water pressure of the water pumped into the valve body shell 1 by the water pump 6.

At this time, the water pumped into the valve body shell 1 by the water pump 6 will flow out of the flushing water outlet 101 and perform the flushing action on the bottom of the toilet. When the piston body 2 moves upward, the return spring 7 is compressed. Specifically, when the water in the water tank is pumped out by the water pump 6, the water pump 6 stops the water pumping action, the water pressure at the lower end of the valve body shell 1 decreases, and the piston body 2 moves downward under the action of the return spring 7 to reset. The piston body 2 drives the water baffle 8 to move downward again to block the flushing water outlet 101 and open the flushing ring outlet 102. When the water inlet valve in the water tank is opened to allow water to enter, the float 4 rises, the swing cover swings downward, the sealing rubber nail 301 blocks the pressure relief hole 105 again, and the system returns to the initial state, completing a flushing cycle.

[0043] Specifically, the bottom of the closestool is communicated with the sewer, and the connection between the sewer and the bottom of the closestool forms a U-shaped structure.

[0044] The application is provided with a water supplement pipe 10 on the flushing water outlet 101, the water supplement pipe 10 is connected with a water supplement pipe, the water supplement pipe is communicated with a water inlet valve in the water tank, the water inlet valve is communicated with external tap water, when the flushing water flow in the flushing water outlet 101 is completed to enter the closestool water tank, the water inlet valve is filled with water in the water tank, at the same time, the water can be discharged to the closestool bottom through the water supplement pipe to block the U-shaped structure of the sewer, so as to avoid the odor of the sewer from spreading to the closestool.

[0045] Preferably, the application is provided with a right-angle structure water guide plate 11 at the position corresponding to the water supplement pipe 10 inside the flushing water outlet 101, the opening of the water guide plate 11 is directed to the opening direction of the flushing water outlet 101, so that the supplemented water will enter the closestool through the flushing water outlet 101 along the water guide plate 11, and will not flow reversely to the inside of the valve body shell 1.

[0046] Specifically, the piston body 2 includes a piston head 201 which is in diameter cooperation with the valve body shell 1 and a piston rod 202 which is connected below the piston head 201, wherein the piston rod 202 is connected with the water baffle 8.

[0047] Specifically, a plurality of insertion columns 2021 are formed on the piston rod 202, and a plurality of connection sleeves 801 for inserting the insertion columns 2021 are formed on the water baffle 8.

[0048] Further, the application is provided with an arc-shaped structure elastic compression part 2022 on the water baffle 8, one end of which is connected with the piston rod 202, and the other end is in abutment with the water baffle 8, since the piston rod 202 and the water baffle 8 are movably connected, when the elastic compression part 2022 is in abutment with the water baffle 8, the water baffle 8 can be compressed to the inner side wall of the valve body shell 1, so as to avoid the large gap between the water baffle 8 and the inner side wall of the valve body shell 1 to cause water leakage.

[0049] Preferably, a first guide rail 103 is vertically arranged on the inner side wall of the valve body shell 1, and a first guide sliding block 2023 arranged on both sides of the piston rod 202 is in sliding cooperation with the first guide rail 103, so that the piston body 2 can move vertically up and down.

[0053] Specifically, if the piston cavity 12 is full of air, even if the pressure relief hole 105 is not opened, when the water pump 6 is turned on, the piston body 2 will compress the air in the piston cavity 12 under the action of water pressure, and will still move up a small distance, driving the water baffle 8 to move up a small distance, resulting in that the flushing water outlet 101 below cannot be completely sealed and water leakage occurs. In the preferred embodiment, the water passing channel 2024 is arranged, and part of the water entering the valve body shell 1 will enter the piston cavity 12 through the water passing channel 2024, preventing the piston cavity 12 from moving up, so that the piston body 2 can only move when the pressure relief hole 105 is opened, thereby ensuring the tightness of the water pump flushing valve.

[0054] Specifically, the diameter of the water passing channel 2024 is smaller than the diameter of the pressure relief hole 105, so that the water flow entering the piston cavity 12 is not too large to cause the water sealing rubber nails 301 to be washed away.

[0055] It should be understood that the above specific embodiments of the present application are only used for illustrative or explanatory purposes of the principles of the present application, and do not constitute a limitation on the present application.
