The first snap ring 101 and the second snap ring 102 can be fixed through the locking screw 12 to form an oval-shaped whole soft rubber water tank snap ring.

As shown in fig. 1-4, the intelligent toilet low water tank control system further includes a first connection pipe 01, a second connection pipe 02, a third connection pipe 03, a distribution valve 05, and a ceramic flushing pipe 08; the ceramic inner wall of the closestool is respectively provided with a ceramic flushing water inlet 06 and a ceramic auxiliary flushing water inlet 07; the distribution valve 05 comprises a distribution valve water inlet connector 054, a distribution valve first water outlet 055 and a distribution valve second water outlet 056;

one end of the first connecting pipe 01 is connected with a water outlet 13 of the plastic water tank, and the other end of the first connecting pipe is connected with a constant-pressure DC water pump 04; one end of the second connecting pipe 02 is connected with the constant-pressure DC water pump 04, and the other end is connected with a water inlet connector 054 of the distribution valve; one end of the third connecting pipe 03 is connected with a second water outlet 056 of the distribution valve, and the other end is connected with the ceramic flushing-assisting water inlet 07; one end of the ceramic scouring pipe 08 is connected with the first water outlet 055 of the distribution valve, and the other end is connected with the ceramic scouring water inlet 06.

In this embodiment, it should be noted that, as shown in fig. 2 and 3, the ceramic inner wall and the ceramic plastic nozzle of the toilet are not shown, and the ceramic plastic nozzle is disposed on the ceramic inner wall of the toilet, and the ceramic flushing water inlet 06 and the ceramic auxiliary flushing water inlet 07 are both connected to the ceramic plastic nozzle.

In practice, the ceramic flushing water inlet 06 is located at the upper part of the ceramic inner wall of the toilet bowl, while the ceramic auxiliary flushing water inlet 07 is located at the lower part of the ceramic inner wall of the toilet bowl. The ceramic flushing water inlet 06 mainly plays a role in flushing the ceramic inner wall of the toilet, and the ceramic auxiliary flushing water inlet 07 plays an auxiliary role in flushing. The ceramic inner wall of the toilet bowl can be better cleaned by arranging the two water inlets. And the constant-pressure DC water pump 04 is used for draining water, so that the noise generated when the ceramic inner wall of the toilet is flushed can be reduced.

Specifically, as shown in fig. 1-3, the distributor valve 05 further includes a distributor valve housing 051 and a distributor valve motor 052 disposed on one side of the distributor valve housing 051, a distributor valve diversion adjusting shaft 053 is disposed in the distributor valve housing 051, and the distributor valve diversion adjusting shaft 053 is connected with the distributor valve motor 052;

the distributing valve water diversion adjusting shaft 053 is arranged between the first water outlet 055 of the distributing valve and the second water outlet 056 of the distributing valve. An O-shaped sealing ring 057 is arranged between the distribution valve shell 051 and the distribution valve water distribution adjusting shaft 053. The water outlet of the water distribution adjusting shaft 053 of the distribution valve is controlled to be connected with the water outlet at the upper part of the ceramic in an opening state (the water inlet valve 4 is communicated to overflow outwards when the water level can not be controlled).

In this embodiment, water enters the water inlet joint 054 of the distribution valve through the second connecting pipe 02, and the water distribution adjusting shaft 053 of the distribution valve is controlled by the motor 052 of the distribution valve to rotate 180 degrees around the shaft, so that the water can flow out from the first water outlet 055 of the distribution valve or the second water outlet 056 of the distribution valve, the water outlets can be switched by the water distribution adjusting shaft 053 of the distribution valve, the positions of the two water outlets are adjusted, the water outlet time and the water outlet direction are controlled, and the purpose of flushing and wiping the ceramic toilet bowl is achieved.

As shown in fig. 1-9, the overall working principle of the present invention is as follows:

when the water inlet valve 4 works normally, the water level does not reach the position of the water tank floating box 7, and the water tank floating box fixing piece 9 can be clamped on the upper surface of the water tank cover 6 because the outline size of the water tank floating box fixing piece 9 is larger than the diameter size of the water tank cover opening 601, so that the water tank floating box 7 is hung on the lower part of the water tank cover 6.

When the water inlet valve 4 is damaged and water is continuously fed, the water inlet valve 4 cannot control the water level, tap water is continuously pumped into the plastic water tank 1, when the water level in the plastic water tank 1 reaches a certain height, the water tank floating box 7 floats upwards, the water tank floating box positioning piece column 702 moves upwards along the water tank cover opening 601 due to the mutual limiting effect of the water tank floating box positioning piece column 702 and the water tank cover opening 601, and finally when the water tank floating box 7 rises to the highest position, the water tank floating box sealing gasket 8 seals the water tank cover opening 601. The water is prevented from overflowing from the opening 601 of the water tank cover, a sealed space is formed inside the plastic water tank 1, and the water in the plastic water tank 1 can only overflow from the plastic water tank water outlet 13 at the bottom of the plastic water tank 1 under the action of the peripheral water pressure.

The water passes through the first connecting pipe 01, the constant-pressure DC water pump 04 and the second connecting pipe 02 in sequence, then enters the water inlet connector 054 of the distributing valve, and the water distributing adjusting shaft 053 of the distributing valve is controlled by the motor 052 of the distributing valve to rotate 180 degrees around the shaft, so that the water can flow out from the first water outlet 055 of the distributing valve or the second water outlet 056 of the distributing valve.

If water flows out from the first water outlet 055 of the distribution valve, the water enters the ceramic scouring pipe 08, then flows to the ceramic scouring water inlet 06, and then scours the ceramic inner wall of the closestool through the ceramic plastic nozzle.

If water flows out from the second water outlet 056 of the distribution valve, the water enters the third connecting pipe 03, then flows to the ceramic auxiliary flushing water inlet 07, and then flushes and rubs the ceramic inner wall of the closestool through the ceramic plastic spray head.
