Abstract

The invention relates to a piezoelectric pump with spiral-line-shaped valves. The piezoelectric pump comprises a piezoelectric vibrator (1), a pump cover (2), a valve base (3), screws (4), a pump base (6), a sealing ring (7), a sealing ring (8) and a screw (9). The pump cover (2) is arranged at the top of the pump base (6). The valve base (3) is arranged at the upper end of the pump base (6). The sealing ring (7) is arranged between the valve base (3) and the pump base (6). The sealing ring (8) is arranged between the valve base (3) and the pump cover (2). The piezoelectric vibrator (1) is arranged at the top of the valve base (3) and arranged between the valve base (3) and the pump cover (2). The piezoelectric vibrator (1) is fixedly connected with the pump cover (2), the valve base (3) and the pump base (6) through the screw (9). A pair of spiral-line-shaped one-way valves (5) inverted to each other is mounted at an inlet and an outlet of the valve base (3) through the screws (4). The piezoelectric pump is simple in structure and low in cost, and can be effectively turned on and off.

Description

technical field [0001] The invention relates to a helical valve piezoelectric pump and belongs to the field of fluid machinery. Background technique [0002] A pump is a machine that moves fluid or transfers energy. Pumps in the traditional sense are generally driven by motors, which have reached a very perfect level no matter in theory, design method or manufacturing technology. However, limited by the working principle and structure, if an additional drive motor is required, the volume will be large, and it will be difficult to control the tiny flow due to electromagnetic interference, so it is difficult to meet the requirements of current aerospace vehicles, robots, automobiles, medical equipment, biogenetic engineering, and micro-machines. application requirements. [0003] Piezoelectric pumps are a new type of fluid actuator. It does not require an additional drive motor, but uses the inverse piezoelectric effect of piezoelectric ceramics to deform the piezoelectric ...
