The present application is described in detail below with reference to the accompanying drawings and examples.
Referring to fig. 1, fig. 1 is an exploded view of an embodiment of a flushing system of a smart toilet. As shown in fig. 1, the flushing system of the intelligent toilet includes: a sealed water tank 10, a direct current variable frequency water pump 20 and a diverter valve 30.
The sealed water tank 10 comprises a tank body 11 and a tank cover 12 which is in sealing connection with the tank body 11 through a water tank sealing ring. Wherein the tank 11 stores a liquid. The liquid includes foam and water, and is not limited herein. The tank gasket is provided at a connection position of the tank cover 12 and the tank body 11 so that the tank body 11 and the tank cover 12 form a sealed connection. The water tank sealing ring is made of resin.
The direct-current variable-frequency water pump 20 comprises a water pump water inlet 21 and a water pump water outlet 22, wherein the water pump water inlet 21 extends towards the liquid direction in the box 11 so as to pump the liquid stored in the box 11 out of the water pump water outlet 22. Wherein the water pump outlet 22 is used for controlling the outflow direction of the liquid.

Specifically, the water diversion valve 30 includes at least two water outlets, and the position and direction of the liquid flowing into the ceramic toilet bowl are controlled by controlling the on/off of the water outlets.
In this embodiment, the water tank cover 12 is further provided with an air inlet hole 121, and a secondary pontoon 122 disposed corresponding to the air inlet hole 121. The auxiliary pontoon 122 moves towards the air inlet under the action of the rising water level, and closes the air inlet 121 after the water level rises to the set water level, so that the water tank cover 12 and the tank body 11 form a sealed air cavity, and the anti-siphon function of the water inlet valve can work normally on the premise that the integral water level in the sealed water tank is lower than the ceramic overflow line. Specifically, the overall water level in the sealed water tank is lower than the ceramic overflow line, and the water level in the water tank is rapidly lowered in a short time when the flushing function is started, and at this time, the auxiliary pontoon 122 opens the air intake hole 121 of the water tank to intake air to the water tank, so that negative pressure is prevented from being formed in the sealed water tank. When the water level in the water tank is reset to the set water level and then the water inlet valve works abnormally and can not stop water inlet, the auxiliary pontoon 122 closes the air inlet hole 121, the water inlet valve continuously inlets water to change the pressure in the water tank from negative pressure to positive pressure, and at the moment, under the action of the positive pressure, more water in the water tank overflows into the ceramic closestool through the water dividing valve, so that a water seal is formed. The auxiliary pontoon 122 closes the air inlet hole 121 to form positive pressure in the water tank, thereby ensuring the normal work of the anti-siphon function of the water inlet valve. Specifically, the liquid in the water tank overflows into the ceramic closestool through the bottom flushing water outlet of the water diversion valve.
In this embodiment, the diverter valve 30 is sealingly connected to the tank cover 12 by a diverter valve seal ring. The direct-current variable-frequency water pump 20 is also in sealing connection with the tank body 11 through a water pump sealing ring, so that a sealed water tank controlled by the auxiliary pontoon 122 is formed.

2. The intelligent toilet flushing system of claim 1, further comprising a fill valve controlling the fill of the sealed tank, the fill valve being fixedly connected to the bottom of the sealed tank by a bottom thread.
3. The intelligent toilet flushing system of claim 1, wherein the direct current variable frequency water pump is arranged corresponding to the lower portion of the tank body, a water pump water inlet of the direct current variable frequency water pump is connected with the side wall of the tank body in a sealing manner through a water pump sealing ring, and a water pump water outlet is connected with a water diversion valve arranged on the water tank cover so as to pump water in the sealed water tank into the ceramic toilet through the water diversion valve.
4. The intelligent toilet bowl flushing system of claim 3 wherein the diverter valve includes side and bottom flush outlets and a diverter valve spool controlling the opening and closing of the bottom flush outlets, the diverter valve spool controlling the opening and closing of the side and bottom flush outlets.
5. The intelligent toilet flushing system of claim 4, wherein the diverter valve comprises a diverter valve spindle disposed on the diverter valve spindle core and a diverter valve motor connected to the diverter valve spindle, and the diverter valve motor drives the diverter valve spindle to rotate by driving the diverter valve spindle to drive the diverter valve core to rotate so as to open and close the bottom flushing water outlet.
6. The intelligent toilet bowl flush system of claim 5, wherein the diverter valve comprises a diverter valve elbow having one end connected to the side flush outlet and the other end connected to the side flush head.
7. The intelligent toilet bowl flushing system of claim 6, wherein a side flush suction pipe is further disposed between the diverter valve elbow and the side flush nozzle, a self-priming tee is further disposed on a side wall of the side flush suction pipe, the self-priming tee includes two water inlets and one water outlet, one of the water inlets is connected with an external waterway, the other water inlet is connected with foam liquid in a secondary liquid tank in the sealed water tank through a hose, and the water outlet is connected with the side flush nozzle so as to suck foam liquid from the secondary liquid tank through a venturi effect of the self-priming tee to mix with liquid in the side flush suction pipe.
8. The intelligent toilet bowl flushing system of claim 7, wherein a side flush air suction duct is further provided therein to increase the flow potential of water flowing through the side flush air suction duct.
9. The intelligent toilet bowl flushing system of claim 4 wherein the low flush outlet of the diverter valve is connected by tubing to an undershoot nozzle within the ceramic toilet bowl that is secured to an undershoot hole of the ceramic toilet bowl by a securing member; wherein, the bottom punching hole is arranged opposite to the sewage outlet of the ceramic closestool.
10. A smart toilet, characterized in that the smart toilet comprises a ceramic toilet and a flushing system connected with the ceramic toilet through a pipeline, wherein the flushing system is the flushing system of the smart toilet according to any one of claims 1 to 9.
