Abstract
A miniature pneumatic device includes a miniature fluid control device and a miniature valve device. The miniature fluid control device includes a gas inlet plate, a resonance plate, a piezoelectric actuator and a gas collecting plate. A first chamber is formed between the resonance plate and the piezoelectric actuator. The miniature valve device includes a valve film and a gas outlet plate. The valve film and the gas outlet plate are stacked on the gas collecting plate. An area of the gas outlet plate is smaller than an area of the gas collecting plate. An adhesive-coating space is defined between four edges of the gas outlet plate and the gas collecting plate. A sealing adhesive is filled in the adhesive-coating space to completely seal a periphery region of the valve film. The first surface and the second surface of the valve film comprise sticking areas.
