MEMBRANE PUMP
First Claim
1. A membrane pump, comprising:
- a chamber body having an inlet pipeline and an outlet pipeline, respectively;
a membrane provided on a top surface of the chamber body; and
an activating element abutting flatly against an upper surface of the membrane, the activating element having a fixed end and a swinging end, the swinging end generating swinging action with one side thereof swinging like a sector,wherein a large range of the swinging action generated by the activating element changes an internal volume of the chamber body, so that the working fluid remaining in the chamber body flows in the inlet pipeline and drains out of the outlet pipeline to generate a flow in one direction.

Abstract
A membrane pump powered by an activating element includes a chamber body. The interior of the chamber body is provided with a first chamber and a second chamber that are in fluid communication with each other. One side or both sides of the chamber body are provided with an inlet pipeline and an outlet pipeline that are in fluid communication with the first chamber and second chamber, respectively. Valves are provided on the inner wall face of same side of the first chamber and the second chamber, thereby preventing the working fluid from generating a backflow phenomenon. Furthermore, the top surface of the chamber body is provided with a membrane. An activating element abuts on the membrane for driving the membrane to swing up and down, thereby pressing the working fluid within the first chamber to circulatively flow in one direction. Via this arrangement, in addition to miniaturize the pump structure to a further extent, the working performance of the pump and the flowing amount of the working fluid are also increased.
