Funnel-shaped valve piezoelectric pump and working method thereof

Abstract

The invention relates to a funnel-shaped valve piezoelectric pump and a working method thereof, and belongs to the field of fluid machinery. A pump body (1) is provided with an inverted conical or round table-shaped pump cavity, a central passage and a lateral passage; a valve body consists of a valve core and a central conduit connected with the valve core; the valve core is also provided with an open valve core inner cavity, and the valve core and the central conduit are combined to integrally form into a funnel shape; the edge of the valve core and the inner wall of the pump cavity form anedge valve port; and the pump cavity is divided into a cavity A and a cavity B by the valve core, wherein the inner wall of the pump cavity and the side wall of the valve core form the cavity A, and the inner wall of the valve core, the inner wall of the pump cavity, a pump cover and a piezoelectric vibrator surround into the cavity B. The edge of a funnel-shaped valve contacts the approximate points on the conical surface of a funnel-shaped cavity, the piezoelectric vibrator vibrates to lead the volume of the pump cavity B to periodically change, and a fluid only can flow into the pump cavity B from the pump cavity A through the boundary of the funnel-shaped valve and can not reversely flow, thereby performing the function of the valve, and achieving the purpose of miniaturization, simplification and convenient installation of the piezoelectric pump.

Description

Technical field [0001] The funnel -shaped valve pump and its working method of the invention belong to the field of fluid machinery, which involves passive valve voltage pumps. Background technique [0002] If the volume volume pump is classified as the valve body is classified, it can be divided into: valve and no valve volume pump.The definition of the valve is: During the inhalation and spitting process of the pump, at least a moment, the pump cavity and the inhaled inlet or vomiting exit can generate discomfort mechanical devices.At present, most of the valve volume pumps are mostly used in the flow pipe litter or the stream pipe end installation parts, which can control the opening and closing of the pipeline through activity components, thereby achieving or preventing the fluid.

AI Technical Summary

Problems solved by technology

[0005] At present, the flow pipe valve body mechanism includes spherical valves, membrane valves, cantilever beam valves and disc valves, etc. Since these valves must be installed in the pipeline or at the end of the flow pipe, the size to be done is very small, which requires processing and processing. It is difficult to install, and there are also disadvantages such as short life, unstable operation, and easy blockage, which is not conducive to the miniaturization of piezoelectric pumps and the improvement of reliability.
