Water purifier, stabilized pressure pump and matching structure of swash plate assembly and membrane of stabilized pressure pump

Abstract

The invention provides a water purifier, a stabilized pressure pump and a matching structure of a swash plate assembly and a membrane of the stabilized pressure pump. The matching structure comprises the membrane and the swash plate assembly. The membrane is installed on the end face of the swash plate assembly. The swash plate assembly comprises a plate body, at least two swinging heads arranged on the plate body and a bearing. The bearing is installed in the plate body. The surface of the membrane is parallel to the surfaces of the swinging heads. An included angle exists between the end face of the bearing and the surface of each swinging head. The end face of the membrane is parallel to the end faces of the swinging heads, so that it is guaranteed that the swash plate assembly makes contact with the membrane effectively and reliably, and the situation that sealing of the swash plate assembly fails due to harmful bending deformation generated by the membrane is avoided when the stabilized pressure pump works; stress concentration of the membrane is reduced, and the risk that the membrane is torn in long-term operation is lowered; meanwhile, it can also be guaranteed that three pressurization cavities are separated and no circulating current is generated, and accordingly it is guaranteed that the output water pressure of the stabilized pressure pump is constant and reliable, and the performance of the water purifier is guaranteed.

Description

technical field [0001] The invention relates to the field of water purification equipment, in particular to a cooperation structure of a water purifier, a pressure stabilizing pump, a swash plate assembly thereof, and a diaphragm. Background technique [0002] At present, with the improvement of people's living standards and the development of the water purification industry, the health of drinking water has become a focus of attention, and more and more water purifiers have entered people's lives. As the core component of the water purifier, the stabilized pump outputs constant and reliable water pressure to ensure the reliable operation of the RO membrane, so that the water purifier can produce high-quality drinking water. [0003] The stabilizer pump belongs to the swash plate diaphragm pump. The swash plate assembly converts the rotational motion of the motor into an axial linear motion. The volume of the diaphragm changes under the drive of the swash plate assembly to f...

AI Technical Summary

Problems solved by technology

However, the diaphragm is prone to harmful bending deformation driven by the swash plate assembly, resulting in circulation in the pressurized chamber, which in turn makes the output water pressure of the stabilizing pump prone to instability, or insufficient water pressure or loss of pressure after a period of operation and other abnormalities, which affect the user's use
