Embodiment Construction
[0037] Specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0038] A valveless piezoelectric pump with a filtering function, including a pump body 1 , a pump cover 2 and a piezoelectric vibrator 3 .
[0039] Such as figure 1 and figure 2 As shown, the pump body 1 is in the shape of a tank. In this embodiment, the cross section of the pump body 1 is circular, including a cylindrical tank body, and the top of the pump body 1 has a circular top opening. The shape of the pump cover 2 matches the shape of the top opening of the grooved pump body 1, and is installed at the top opening of the pump body 1. The pump cover 2 covers the notch of the pump body 1 and forms a pump chamber structure with the pump body 1. A fluid inlet 101 and a fluid outlet 102 are provided on the side wall of the trough-shaped pump body 1; when the valveless piezoelectric pump is working, the fluid flows in through the fluid inlet ...

A valveless piezoelectric pump with a filtering function comprises a pump body, a pump cover and a piezoelectric vibrator. The pump body is in a circular groove shape. The pump cover is matched with a top opening of the circular-groove-shaped pump body in shape and is arranged at the position of the top opening of the pump body, and a pump cavity structure is formed by the pump cover and the pump body. A fluid inlet and a fluid outlet are formed in the side wall of the circular-groove-shaped pump body. A filtering ring is arranged in the pump cavity and comprises a filtering ring body. The pump cavity is internally provided with a lap joint table, and the filtering ring body is arranged on the lap joint table. The filtering ring body is provided with a filtering hole. The filtering ring comprises a section of annular side wall, and the upper end face and the lower end face of the side wall extend towards the outer side of the filtering ring. The fluid inlet and the fluid outlet are located between the upper end face and the lower end face of the filtering ring, and a filtering cavity is formed by the filtering ring and the inner wall of the pump body in a surrounding manner. An outflow through hole communicating with the fluid outlet is formed in the inner wall filtering ring. The valveless piezoelectric pump with the filtering function is provided and is capable of filtering fluid in the fluid pumping process, and the application field of the valveless piezoelectric pump is enlarged.
Description
technical field [0001] The invention belongs to the technical field of fluid machinery and relates to a valveless piezoelectric pump, in particular to a valveless piezoelectric pump with filtering function. Background technique [0002] In the fields of chemical analysis and detection, bioengineering, heat dissipation and cooling of integrated circuit chips, micro components, and miniaturized production systems (micro factories), there is an urgent need for high-performance, high-reliability micro-flow liquid delivery devices, which make micro The development and research work of flow fluid pump has important practical significance. [0003] Piezoelectric pump, as a new type of fluid driver in the field of micropumps, is the product of the combination of piezoelectric drive technology and fluid pump technology. Piezoelectric drive technology is a technology that uses the inverse piezoelectric effect to drive mechanisms or fluid motion. [0004] In recent years, with the ra...
