[0002] Environmental sanitation is an important factor affecting the quality of life. Therefore, with the continuous improvement of people's requirements for quality of life, the corresponding requirements for environmental sanitation are also getting higher and higher. However, the work pressure of modern people is increasing day by day, and they are in urgent need of being liberated from the heavy cleaning work. Therefore, many ground cleaning equipment have appeared to improve environmental sanitation, and the commonly used ones are vacuum cleaners, automatic mops, sweepers and floor washers. Floor washers are a kind of equipment used to clean the ground. The current floor washers have been developed to have relatively complete functions. The working principle of the floor washers is to spray clean water or detergent from the clean water tank to the ground. After cleaning, the sewage on the ground can be sucked into the sewage tank in the floor washers again, thus completing the cleaning process.

[0003] At present, the existing water storage tank is placed on the floor brush assembly, and the water pump motor assembly is also installed on the floor brush assembly, which can reduce the water delivery length. However, the water outlet sealing effect of the water pump motor assembly is poor, which will cause water leakage and thus cause a short circuit problem in the circuit. Utility Model Content
