Actuating device

Abstract

An actuating device comprises an actuating part, a piezoelectric unit, a bearing part, an adjusting layer, a conduction unit and a perforated sheet. The actuating part comprises a first actuating area, a second actuating area and at least one connecting section. The piezoelectric unit comprises a first through hole, a first signal area and a second signal area, and the two signal areas are electrically insulated from each other. The bearing part and the piezoelectric unit are located on the same plane. The adjusting layer is located on the same side surface of the piezoelectric unit and the bearing part. The conduction unit comprises a first conduction area, a second conduction area and a second through hole, the first signal area of the piezoelectric unit is electrically connected to the first conduction area of the conduction unit, and the second signal area of the piezoelectric unit is electrically connected to the second conduction area of the conduction unit. The perforated sheet is arranged at the corresponding positions of the first through hole and the second through hole, penetrates through the two through holes and then is fixed to the actuating part.

Description

technical field [0001] The present invention relates to an actuating device, in particular to an actuating device whose overall composition structure has uniform flatness through the design of the adjustment layer. Background technique [0002] The piezoelectric pump is a new type of fluid driver. It does not need an additional drive motor. It can deform the piezoelectric vibrator only through the inverse piezoelectric effect of the electroceramic, and then generate the volume change of the pump chamber according to the aforementioned deformation to achieve fluid output. Or the fluid can be transmitted through the vibration of the piezoelectric vibrator, so the piezoelectric pump has gradually replaced the traditional pump and is widely used in electronics, biomedicine, aerospace, automobile and petrochemical industries [0003] Generally speaking, a piezoelectric pump is composed of a piezoelectric unit and a pump body. When the piezoelectric unit is energized, the piezoele...
