Embodiment Construction
[0014] The specific embodiment of the present invention will be described with reference to the accompanying drawings.
[0015] Such as figure 1 As shown, the piezoelectric jet type precise quantitative dispensing device includes a piezoelectric stack PZT driver 1, a primary amplification mechanism 2, a triple amplification mechanism 3 and a mechanical base 11;
[0016] The primary amplification mechanism 2 adopts the triangular amplification principle. The primary amplification mechanism 2 includes an elastic amplification mechanism body 202 and two elastic metal sheets 201. The elastic amplification mechanism body 202 is an integral structure cut by wire. The two elastic metal sheets 201 Using 65Mn material with relatively large elastic modulus, the piezoelectric stack PZT driver 1 is embedded in the body 202 of the elastic amplification mechanism through interference fit; the piezoelectric stack PZT driver 1 is connected to the piezoelectric ceramic high-voltage power suppl...
