Abstract

The invention discloses an integrated valve piezoelectric pump based on a diamond-shaped amplifying mechanism, which is composed of a pump body, a piezoelectric stack, screws, an end cover, and a diamond-shaped integrated valve. The liquid inlet plug, the right liquid outlet plug, the left liquid outlet plug and the diamond-shaped integrated valve on the diamond-shaped integrated valve are an integral structure. The outflow port, when the liquid inlet plug leaves the inflow port, the right liquid outlet plug and the left liquid outlet plug push into the right outflow port and the left outflow port to block the fluid or make the fluid circulate, and play a role similar to a valve. The wall and upper arm move along with the diamond-shaped integrated valve in the pump chamber to change the volume of the pump chamber formed by the pump body and the end cover, and form a pressure difference in the pump chamber to make the liquid be sucked or discharged.

Description

technical field [0001] The invention relates to an integrated valve piezoelectric pump based on a rhombus amplifying mechanism, belonging to the field of fluid machinery. Background technique [0002] Applying the inverse piezoelectric effect of the piezoelectric stack to the valveless piezoelectric pump can realize the circulating output of the liquid. Because the valveless piezoelectric pump has the advantages of small size and no electromagnetic interference, it has attracted much attention in recent years. However, the valveless piezoelectric pump also has the shortcomings of serious backflow and low output flow, which makes it difficult for the valveless piezoelectric pump to be widely used in daily life. SUMMARY OF THE INVENTION [0003] Aiming at the problems existing in the current valveless piezoelectric pump, the present invention proposes an integrated valve piezoelectric pump that can relieve backflow and have a high output flow. [0004] The technical scheme ...
