Abstract

The invention discloses a miniature pneumatic power device which comprises a miniature air transmission unit. The miniature air transmission unit comprises an air intake plate, a runner plate, a resonance piece and a piezoelectric actuator which are arranged by stacking, a gap reserved between the resonance piece and the piezoelectric actor forms a first chamber, and when the piezoelectric actuator is driven, air is led into the first chamber from the air intake plate via the runner plate and the resonance piece and then transmitted downwards, and a pressure gradient runner is formed to have the air continuously pushed out; a miniature valve unit comprises an air collecting plate, a valve slice and an outlet plate which are arranged by stacking; when downwardly transmitted to an air collecting chamber from the miniature air transmission unit, the air is then transmitted to the interior of the miniature valve unit, so that a valve hole of the valve slice is enabled to be opened or closed due to one-way flow of the air to perform pressure collecting or pressure releasing.

Description

technical field [0001] The invention relates to a pneumatic power device, in particular to a miniature ultra-thin and quiet micro pneumatic power device. Background technique [0002] At present, in various fields, whether it is medicine, computer technology, printing, energy and other industries, products are developing towards refinement and miniaturization. Among them, micro pumps, sprayers, inkjet heads, industrial printing devices and other products include products. The fluid conveying structure is its key technology, so how to break through its technical bottleneck with an innovative structure is an important content of development. [0003] For example, in the pharmaceutical industry, many instruments or equipment that need to be driven by pneumatic power usually use traditional motors and pneumatic valves to achieve the purpose of gas delivery. However, limited by the volume limitations of the traditional motors and gas valves, it is difficult to reduce the volume ...
