The outlet 126 of the second end of the outlet conduit 33 is arranged above the lowest overflow surface of the toilet, and the outlet 126 of the main body 12 is connected to a pressurizing device through a conduit and then connected to the main body of the toilet, and the pressurizing device pumps water from the water tank 100 into the main body of the toilet.

When the valve body 22 of the water inlet valve 2 is switched on, running water supplied from a water source enters the accommodating cavity 121 until the water level rises to a preset height, at the moment, the valve body 22 is switched off, and the water inlet valve 2 stops water inlet; when the water level drops due to the consumption of the water in the accommodating chamber 121 during the toilet flushing, the valve body 22 of the water inlet valve 2 is conducted again, and the above process is repeated. If the valve body 22 cannot be closed due to the failure of the water inlet valve 2, the water level in the accommodating cavity 121 rises continuously, the water level cannot rise continuously in the air cavity 111 after rising to a preset height due to the air pressure generated by the air sealed in the air cavity 111, and the water level is lower than the outlet of the second end of the output pipeline 23, at the moment, surplus water is discharged through an overflow channel at the overflow port 123, enters a flushing tank of the toilet through the second end of the water outlet pipeline 33, and is discharged to a sewer through a sewage discharge pipeline; if the overflow pipe 3 is blocked and cannot drain water, the water level in the air cavity 111 is also maintained at a predetermined height due to the air pressure in the air cavity 111; when the sewage in the toilet body is poured into the water tank 100 due to a siphon action in the pipe communicating between the water tank 100 and the toilet body, the water level in the air chamber 111 is also maintained at a predetermined level due to the air pressure in the air chamber 111. In summary, due to the effect of the air pressure in the air chamber 111, the water surface in the water tank 100 cannot submerge the outlet of the second end of the output pipeline 23, and when the water supply source generates negative pressure during water cut-off, the water in the water tank 100 can be prevented from flowing back to the water supply source through the output pipeline 23, which causes water source pollution.

Because the position of the outlet of the water outlet pipe 33 is higher than the main body 12 of the water tank 100, the water tank 100 can set the main body 12 at a position lower than the lowest overflow surface of the toilet bowl in the practical process, as long as the second end of the water outlet pipe 33 is set on the lowest overflow surface of the toilet bowl, the water is pumped into the toilet bowl without adding a pressurizing device, the water in the water tank 100 can be discharged into a toilet bowl flushing tank by utilizing the water pressure of a water supply source, and meanwhile, the situation that when a toilet drain pipe is blocked, the water level in the toilet bowl is higher than the outlet of the second end of the water outlet pipe 33, so that the sewage flows back into the accommodating cavity 121 through the overflow pipe 3 can be avoided.

The intelligent closestool also comprises a control box and an electric water pump, the control box and the electric water pump are arranged in the space around the water tank 100 behind the closestool, and the water tank 100 is of a sealing structure and can prevent water vapor in the water tank 100 from damaging electric equipment.
