Abstract

The invention discloses an inertia pump with a three-piezoelectric-stack rhombus amplification structure. The inertia pump is composed of a flow pipe, a wheel type one-way valve, an umbrella type one-way valve, a cantilever beam, a cantilever beam screw, a cantilever beam mass block, a pump body, the rhombus amplification structure, a small stack cover, a small stack cover screw, a large stack cover, a large stack cover screw, small piezoelectric stacks and a large piezoelectric stack, wherein the included angle between an upper arm and a lower arm of the rhombic amplification structure is 60degrees, so that the best effect of transmitting the the rhombic amplification structure and amplifying the movement and displacement of the small piezoelectric stacks and the large piezoelectric stack is achieved, the driving part is provided with three stacks, namely two small piezoelectric stacks and one large piezoelectric stack which are connected to two independent power supplies with opposite phases, so that the small piezoelectric stacks and the large piezoelectric stack move in opposite directions, the flow pipe is provided with a one-way valve installation base, and the wheel type one-way valve and an umbrella type one-way valve and the umbrella type one-way valve can be selected and arranged on the one-way valve installation base and used for reversely stopping liquid backflow.

Description

technical field [0001] The invention relates to an inertial pump with triple piezoelectric stacked diamond-shaped enlarged structure, which belongs to the field of fluid machinery. Background technique [0002] Applying the inverse piezoelectric effect of piezoelectric ceramics to the inertial pump can realize the circulation output of the liquid. Due to the advantages of simple structure and easy layout, the inertial pump has attracted people's attention in recent years. However, the inertial pump also has the complexity of the driving part. , The obvious shortcomings of electromagnetic interference make it difficult for inertial pumps to be widely used in daily life. Contents of the invention [0003] Aiming at the problems existing in the current inertial pumps, the invention proposes an inertial piezoelectric pump with simple structure and high output flow. [0004] The technical scheme adopted in the present invention is: a kind of inertial pump with triple piezoelec...
