The through hole 111 is for discharging air that enters when the water pump 11 is in operation.

When the water pump 11 is operating normally, a water flow enters the inside of the water pump 11 from the water inlet, and the water flow obtains energy under the action of the water pump 11 to flow out to the pipe 13 at the water outlet. During the pumping of the water pump 11, the outside air will enter the water pump 11 together, and the water flow together will enter the pipeline 13, causing the water flow in the pipeline 13 to be unstable. Therefore, the through hole 11 is opened in the water pump 11 so that air entering the water pump 11 can be discharged from the through hole 111, so that the water flowing into the pipe 13 does not entrain air, thereby ensuring the pipe 13 The water flow inside is stable.

The water pump 11 of the present invention may be any water pump capable of realizing a pumping function, and the motor 15 may be any motor that drives the water pump 11 to operate.
