Abstract

The invention discloses an inertial pump with triple piezoelectric stacked diamond-shaped amplifying structure, which consists of a flow tube, a wheel-type check valve, an umbrella-type check valve, a cantilever beam, a cantilever beam screw, a cantilever beam quality block, a pump body, and a diamond-shaped amplifying pump. Structure, small stack cover, small stack cover screw, large stack cover, large stack cover screw, small piezoelectric stack, and large piezoelectric stack. The included angle between the upper and lower arms of the diamond-shaped amplifying structure is 60°, so that the diamond-shaped amplifying mechanism has the best effect of transmitting and amplifying the movement and displacement of the small piezoelectric stack and the large piezoelectric stack. There are three stacks in the driving part. Two small piezoelectric stacks and one large piezoelectric stack are connected to two sets of independent power supplies with opposite phases, so that the small piezoelectric stack and the large piezoelectric stack move in opposite directions. The flow pipe is provided with a one-way valve mounting seat, and a wheel-type one-way valve or an umbrella-type one-way valve can be selected to be placed on the one-way valve mounting seat to reversely stop the liquid return flow.

Description

technical field [0001] The invention relates to an inertial pump with a three piezoelectric stacking rhombus amplifying structure, belonging to the field of fluid machinery. Background technique [0002] Applying the inverse piezoelectric effect of piezoelectric ceramics to the inertia pump can realize the circulating output of the liquid. Because the inertia pump has the advantages of simple structure and easy layout, it has attracted much attention in recent years. However, the inertia pump also has a complex driving part. , The obvious shortcomings of electromagnetic interference make it difficult for inertial pumps to be widely used in daily life. SUMMARY OF THE INVENTION [0003] Aiming at the problems existing in the current inertial pump, the present invention proposes an inertial piezoelectric pump with simple structure and high output flow. [0004] The technical scheme adopted in the present invention is: a three piezoelectric stacked rhombus amplifying structur...
