Abstract: Cleaning equipment includesa water divider structure comprisinga pressuresource connected to a water supply tank, a water divider provided with a first distribution channel and a second distribution channel, wherein the first and second distribution channels both are connected with the pressuresource, anda first unidirectional valve connecting between the pressuresource and the water divider, wherein the first unidirectional valve connects through the pressuresource and the water divider under pressure formed when the pressuresource is activated. When there is residual water in the pipeline between the first unidirectional valve and the water divider structure, the first unidirectionalvalve can prevent the water in the water supply tank from being transported downstream. At this time, there is water in the pipeline downstream of the first unidirectionalvalve. One end is closed, and one end of the water divider structure is connected to the outside.
