摘要

Valve-less piezoelectric pump is more suitable for minimization and microminiaturization than valve piezoelectric pump because of its simple structure.However,in order to control the flow direction of the fluid through the pump,some assembles have to be attached outside the chamber.And it is no doubt that these assembles will take some space and hinder its further microminiaturization.In this paper,a novel valve-less piezoelectric pump with cluster of unsymmetrical humps structure (CUHS) is presented.It ingeniously takes advantage of the space of the chamber by developing its bottom into an unsymmetrical humps shape along the axis of the inlet and outlet.Then,the theory on the pump working is presented briefly.Finally,a real CUHS valve-less piezoelectric pump is manufactured,and the experiment is carried out.The different between the theoretical calculation and the experimental value is compared.The test verifies the theory on the pump well.
