Embodiment Construction
[0012] refer to figure 1 , the cavity valve integrated piezoelectric pump of the present invention is composed of a piezoelectric vibrator 1 and an integrated cavity valve component 2, wherein:
[0013] The piezoelectric vibrator 1 is installed on one side of the integrated cavity valve part 2; the integrated cavity valve part 2 is made of a rubber material or rubber and plastic materials, and the vibrator installation groove is arranged on the integrated cavity valve part 21. The piezoelectric vibrator 1 is installed in the vibrator installation groove 21, and a cavity sinker 22 is arranged in the center of the vibrator installation groove 21. After the piezoelectric vibrator 1 is installed, the cavity sinker 22 forms a sealed cavity, that is, a pump cavity. A diversion groove 23 is arranged at the bottom of the cavity sinker 22, and the inlet 24 and outlet 25 of the cavity are arranged at the bottom of the diversion groove 23; the inlet 24 is a cylindrical structure with an ...
