Abstract

The invention is an electrical connection structure for a miniature piezoelectric pump, comprising: a driving circuit board and a wire structure composed of multiple single layers. From top to bottom, it is the drive circuit board, the wire structure, and the piezoelectric film. The drive circuit board is provided with a drive circuit for driving the piezoelectric sheet, and at least one electric contact is provided on the drive circuit board, wherein the electric contacts are electrically connected to the drive circuit. The piezoelectric sheet is on the same surface, and a first electrode contact area and a second electrode contact area electrically isolated from each other are provided. The wire structure is used to transmit the signals of the electrical contacts 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] like 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 above...
