A diaphragm pump with an exhaust structure and the water supply system thereof
By designing an exhaust structure and air control components in the diaphragm pump and controlling the airflow by rotating the motor in both directions, the pumping and exhaust functions of the diaphragm pump are realized. This solves the problem in the prior art that the diaphragm pump cannot pressurize in the initial state and after the water in the tank has been delivered. It also simplifies the pipeline structure of the water supply system and reduces costs.

Abstract
This invention discloses a diaphragm pump with an exhaust structure and a water supply system thereof, including a pump head body and a motor. The pump head body has an inlet, an outlet, and a pressurization chamber. The pressurization chamber is connected to the inlet and outlet respectively through a unidirectional water flow structure. An exhaust structure is provided below the motor. The exhaust structure includes a housing, an air inlet, an air outlet, and an air passage chamber connecting the air inlet and outlet. An air control component is provided in the air passage chamber. Above the air control component is a drive component connected to an extension shaft of the motor's rotating shaft. The motor drives the drive component to move up and down and drives the air control component to control the airflow to open or close. In application, this invention can simplify the piping and corresponding components required for diaphragm pump exhaust in the water supply system, reducing overall cost.
