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.

Abstract: A sewage tank structure for a cleaning apparatus, and a cleaning apparatus. The sewage tank structure comprises a sewage tank (110). A first flow channel (110a) and a second flow channel (110b), provided with the sewage tank (110), both connecting through an inside portion and an outside portion of the sewage tank (110), the first flow channel (110a) divides a fluid stream flowing to the sewage tank (110) into multiple fluid streams to make the multiple fluid streams collide in the sewage tank (110), the second flow channel (110b) discharges air in the sewage tank (110). After the air-incorporated sewage and garbage is divided into multiple fluid steams through the first flow channel (110a), each fluid stream of air-incorporated sewage and garbage undergoes an air-liquid separation process during the downward flow into the sewage tank (110). During the air-liquid separation process, every fluid stream of the air-incorporated sewage and garbage collides with each other in the sewage tank (110), so that the kinetic energy of each fluid stream of the air-incorporated sewage and garbage is reduced, cancelled out, or at least cancelled out in part due to the above collisions. Therefore, the sewage and garbage is able to flow into the sewage tank more smoothly and fluently. The separated air collides with the air of other fluid streams in the sewage tank structure, thus reducing its own kinetic energy, enabling the suction producing device to more easily suck the separated air away through the second flow channel (110b).
