The piezoelectric vibrator comprises a circular base body 3-2, and piezoelectric ceramics 3-1 are arranged on the upper surface of the circular base body.

Through the inverse piezoelectric effect, the piezoelectric ceramic 3-1 deforms, expands and contracts, drives the substrate 3-3 to vibrate up and down, changes the pressure of the pump cavity, and sucks and pumps out the mixed liquid.

Through the action of the piezoelectric vibrator 3, fluid enters the pump cavity from the pump body inlet 1-5 through the pump body inlet channel 1-7 of the pump body 1 through the cross silica gel valve 10 and is finally pumped out through the pump body outlet 1-6.

When fluid flows through the front-end cross silica gel valve 10 and the rear-end cross silica gel valve 10, the energy loss of the fluid is small, and the fluid flow is facilitated.

When the fluid passes through the inlet channels 1-7 of the Y-shaped pump body, the fluid is preliminarily mixed at the intersection, and the energy loss of the fluid is small when the fluid flows through the cross silica gel valve 10, so that the fluid mixing effect is facilitated.
