Abstract

The invention discloses an integrated valve piezoelectric pump based on a rhombus amplification mechanism. The integrated valve piezoelectric pump is composed of a pump body, a piezoelectric stack, screws, an end cover and a rhombus integrated valve, wherein a liquid inlet plug, a right liquid outlet plug, a left liquid outlet plug and the rhombus integrated valve on the rhombus integrated valve are of an integrated structure, the right liquid outlet plug and the left liquid outlet plug leave a right outflow port and a left outflow port when the liquid inlet plug is ejected into an inflow port, the right liquid outlet plug and the left liquid outlet plug are ejected into the right outflow port and the left outflow port when the liquid inlet plug leaves the inflow port, and used for blocking fluid or enabling the fluid to communicate, the similar-valve effect is achieved, and the lower wall and an upper arm of the rhombic integrated valve do planar motion in a pump cavity along with therhombic integrated valve, so that the volume of the pump cavity formed by the pump body and the end cover is changed, pressure difference is formed in the pump cavity, and the liquid is sucked in ordischarged out.

Description

technical field [0001] The invention relates to an integrated valve piezoelectric pump based on a diamond-shaped amplifying mechanism, which belongs to the field of fluid machinery. Background technique [0002] The inverse piezoelectric effect of the piezoelectric stack is applied to the valveless piezoelectric pump, which can realize the circulation output of the liquid. Because the valveless piezoelectric pump has the advantages of small size and no electromagnetic interference, it has attracted people's attention in recent years. However, valveless piezoelectric pumps also have the disadvantages of serious backflow and low output flow, which makes it difficult for valveless piezoelectric pumps to be widely used in daily life. Contents of the invention [0003] Aiming at the problems existing in the current valveless piezoelectric pump, the present invention proposes an integrated valve piezoelectric pump capable of alleviating backflow and having high output flow.
