Water pump with self-cleaning function

The invention relates to a water pump, in particular to a water pump with a self-cleaning function. According to the water pump with the self-cleaning function, impurities can be cleaned conveniently while water pumping is conducted, the impurities can be filtered out, and pipeline blockage is avoided. A water pump with a self-cleaning function comprises a base, a supporting plate, a motor, a rotating disc and the like. A supporting plate is fixedly connected to the upper end of the base, a motor is fixedly installed on the upper side face of the supporting plate, and a rotating disc is fixedly connected to one end of an output shaft of the motor. The second transmission disc rotates to drive the first transmission disc and the large overrun clutch to rotate, the large overrun clutch drives the rotating pipe to rotate, and due to the fact that the rotating pipe is in sliding connection with the rod sealing ball, the rotating pipe can rotate to drive the rod sealing ball to rotate, so that the rod sealing ball
