Referring to fig. 3, the bottom wall of the sewage tank 13 is disposed obliquely to form an angle with the horizontal plane, and the water suction port of the drain pump 19 is connected below the bottom wall of the sewage tank 13. When the liquid level in the sump 13 gradually decreases, the sewage is collected at the suction port of the drain pump 19, so that complete emptying of the sump 13 can be achieved.
Wherein the clean water tank 12 and the sewage tank 13 are integrally formed. Specifically, the fresh water tank 12 and the sewage tank 13 may be integrally formed of the housing 11, in other words, the inner receiving space of the housing 11 forms the fresh water tank 12 and the sewage tank 13.

When the water level exceeds the highest position of the siphon tube 162, water flows out from the outlet to form a siphon, and under the action of the siphon, clean water continuously flows in from the clean water tank 12 to the communicating pipe 16 and is sprayed out from the outlet of the siphon tube 16, so that a spraying effect is generated, and a flushing effect can be generated on the sewage tank.
In a particular embodiment, the outlet of siphon tube 162 is higher than the end of first end 1610. Siphon 162 is inverted U-shaped.
In order to ensure proper spraying of the siphon tube 162, the outlet of the siphon tube 162 is higher than a preset level for triggering the drainage mechanism, that is, the level of the sewage tank is always kept below the outlet of the siphon tube 162, so that the sewage does not close the outlet of the siphon tube 162, and thus the siphon cannot be performed.
The automatic water supply and drain device 1 further includes a cover 14 for sealing the clean water tank 12 and the sewage tank 13. Sealing rings are arranged between the cover 14 and the clean water tank 12 and the sewage tank 13, so that the clean water tank 12 and the sewage tank 13 can be isolated from external air pressure.
