Micro Pneumatic Power Device

Abstract

The present invention relates to a micro-pneumatic power device, comprising: a micro-gas transmission device, including stacked intake plates, flow channel plates, resonant plates and piezoelectric actuators, wherein there is a gap between the resonant plates and the piezoelectric actuators. A first chamber formed by the gap, when the piezoelectric actuator is driven, the gas is introduced from the inlet plate, passes through the flow channel plate and the resonant plate, enters the first chamber, and then transmits downward to form a pressure gradient flow The gas channel continuously pushes out the gas; the micro valve device includes a stacked gas collecting plate, valve plate and outlet plate; when the gas is transported downward from the micro gas transmission device to the gas collecting chamber, it is then transferred to the micro valve device to respond to the gas flow. The valve hole of the valve plate is opened or closed to collect or relieve pressure.

Description

Technical field [0001] The invention relates to a pneumatic power device, in particular to a miniature, ultra-thin and silent 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 in the direction of refinement and miniaturization. Among them, products such as micro pumps, sprayers, inkjet heads, and industrial printing devices include Fluid transportation structure is its key technology, so how to break through its technical bottleneck by 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 these traditional motors and gas valves, it is difficult for this type of equipme...
