Embodiment Construction
[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. (but protection scope of the present invention is not limited to this.)
[0032] A piezoelectric pump with a spring valve body and a valve is mainly composed of a pump body, a piezoelectric chip, a rigid element, an elastic diaphragm, an elastic film, an inlet check valve, an outlet check valve and a controller. The left and right sides of the pump body are symmetrically arranged, and the inlet and outlet valve bodies are arranged in the same direction, so that when one of the valve bodies is open and working, the other is in a closed state, which can realize one-way transmission of liquid.
[0033] In the present invention, the pump body adopts 3D printing technology and uses plastic high molecular polymer, which has strong rigidity and high strength. Preferably, the one-way valve in the present invention is made of polymer rubber, which has good toughn...
