The two sides of the water pumping pipe 5 are respectively fixedly connected to the two groups of water storage tanks 1. Two groups of water outlet valves 6 are fixedly installed on both sides of the water pumping pipe 5. The water outlet valves 6 are electronic valves. By setting the two groups of water outlet valves 6, the two groups of water storage tanks 1 can be controlled separately. When flushing, the water supply to one group of water storage tanks 1 can be suspended to facilitate flushing; the water pump 4 is fixedly installed on the mounting plate 7, and the mounting plate 7 is fixedly installed on the support frame 2. The water supply structure also includes a frequency converter 13 and a pressure sensor 14. The frequency converter 13 is electrically connected to the water pump 4. The frequency converter 13 is fixedly installed on the mounting plate 7. The pressure sensor 14 is fixedly installed at the water outlet end of the water pump 4.

By setting the pressure sensor 14 and the frequency converter 13 to cooperate with the water pump 4, the pumping efficiency of the water pump 4 can be adjusted according to the water pressure in the water supply pipeline to ensure the stability of the water pressure in the water supply pipeline.

[0028] The flushing structure also includes a flushing structure, which includes a plurality of nozzles 8, which are fixedly mounted on the side wall of the movable seat 9.

More comprehensive flushing further improves the flushing effect; the movable seat 9 is fixedly connected to the bottom of the hose 17, the top of the hose 17 is fixedly connected to the top of the water storage tank 1, the bottom of the hose 17 is connected to the nozzle 8, the top of the hose 17 is connected to the flushing pipe 18, the top of the flushing pipe 18 is fixedly connected to the main water inlet pipe 3, and a flushing valve 19 is fixedly installed on the flushing pipe 18.
