Improved water pump

The utility model relates to an improved water pump, which comprises a pump body, an impeller, a water inlet, and a water outlet. The improved water pump is characterized in that one side of the water inlet of the pump body is integrally provided with a collecting chamber of sundries, and the internal part of the collecting chamber of the sundries is sheathed with a filter. Since the utility model adopts a structure of the collecting chamber which is provided with the filter; in the working process of the water pump, the sundries in the water which enter the impeller can stay in the collecting chamber of the sundries through the filter, and accordingly, the sundries can be effectively prevented from being adsorbed on the impeller; normal operation of the water pump and the motor can be ensured, and the situation of the sundries in the collecting chamber can be conveniently observed. The improved water pump has the advantages of simple structure, reliable use, and strong practicability.
