In a specific embodiment, a three-way pipe is communicated with the water flow port 111 of the clean water tank 11 of the water tank structure 1, and the other two ends of the three-way pipe are respectively provided with a flow stopping water pump.

The embodiment also provides a cleaning system which comprises the cleaning dock and the cleaning equipment. Wherein the cleaning dock is used for providing clean water required by the cleaning device and/or receiving sewage discharged by the cleaning device. Two water stop pumps on the cleaning device respectively act on the cleaning dock and the rolling brush assembly.

In this embodiment, for convenience of description, a water stop pump acting on the cleaning dock is referred to as a water make-up pump, and a water stop pump acting on the rolling brush assembly is referred to as a working pump.

In the working process of the cleaning equipment, the water supplementing pump works first, clean water is sucked out of the cleaning dock and flows into the clean water tank through the three-way pipe, and at the moment, the working pump is in a stop state and keeps a flow stopping state, so that water flow is prevented from flowing into the rolling brush assembly. After the clean water tank is full, the water supplementing pump stops working and keeps a flow stopping state. At the moment, the rolling brush is driven, the working pump starts to work, and clean water in the clean water tank is sucked out and flows into the rolling brush assembly.

Through the design of the structure, the water inlet and the water outlet of the clean water tank can be combined into one water flow port, so that the structural complexity of the clean water tank is simplified, the cost is reduced, the work is more reliable, and the risk of water leakage caused by more openings of the water tank is prevented.

The cleaning dock is also communicated with a water outlet of the sewage tank, and the water outlet is also provided with a stop valve. And (3) discharging the sewage in the sewage tank, vacuumizing the clean dock to pump out the sewage, and discharging the sewage out of the water tank through a stop valve.

The foregoing descriptions of specific exemplary embodiments of the present invention are presented for purposes of illustration and description. It is not intended to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain the specific principles of the invention and its practical application to thereby enable one skilled in the art to make and utilize the invention in various exemplary embodiments and with various modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the claims and their equivalents.
