Abstract

The invention relates to an electrically connecting structure applied to a micro piezoelectric pump, comprising a driving circuit board and a lead structure consisting of a plurality of single layers.The electrically connecting structure sequentially comprises the driving circuit board, the lead structure and piezoelectric patches from top to bottom. The driving circuit board is provided with a driving circuit which is used for driving the piezoelectric patches and at least more than one electrically connecting point, wherein the electrically connecting points are electrically connected withthe driving circuit. The piezoelectric patches are arranged on the same surface on which a first electrode contact area and a second electrode contact area which are mutually and electrically isolatedare arranged. The lead structure is used for transmitting signals of the electrically connecting points to the first electrode contact area and the second electrode contact area.

Description

technical field [0001] The invention relates to a piezoelectric (Piezoelectric) miniature piezoelectric pump, and in particular to a miniature piezoelectric pump with an internal wire structure. Background technique [0002] Such as figure 1 As shown, the electrical connection means between the driving circuit board 1 and the piezoelectric sheet 2 of the known miniature piezoelectric pump is to use two electric wires 1a to connect. Two ends of the wires 1 a are welded to the driving circuit board 1 and the piezoelectric film 2 respectively. When the known miniature piezoelectric pump is further designed to be miniaturized, the electric wires 1a will hinder the design of the miniaturized pump. [0003] In view of the fact that the above-mentioned known miniature piezoelectric pump still has room for improvement, the inventor of the present invention desperately wants to invent a wire structure between the driving circuit board and the piezoelectric sheet to replace the abov...
