Miniature gas control device

A miniature gas control device, comprising:

• at least one miniature gas transportation device comprising:
• at least one protective film having a waterproof and dustproof film structure allowing gas to pass therethrough;
• at least one gas inlet plate comprising at least one inlet;
• at least one resonance plate;
• and
• at least one piezoelectric actuator;
• wherein the at least one protective film, the gas inlet plate, the resonance plate and the piezoelectric actuator are stacked on each other sequentially to be positioned, and at least one gap is formed between the resonance plate and the piezoelectric actuator to define at least one first chamber, wherein when the piezoelectric actuator is enabled, the gas is fed into the miniature gas transportation device through the at least one inlet of the gas inlet plate, transferred through the resonance plate, introduced into the first chamber, and further transferred along a transportation direction;
• and
• at least one miniature valve device comprising:
• at least one gas collecting plate comprising at least two perforations and at least two chambers,
• at least one valve film comprising a valve opening;
• and
• at least one gas outlet plate comprising at least two perforations and at least two chambers;
• wherein the gas collecting plate, the valve film and the gas outlet plate are stacked on each other sequentially to be positioned and at least one gas-collecting chamber is formed between the miniature gas transportation device and the miniature valve device, wherein after the gas is transferred from the miniature gas transportation device to the gas-collecting chamber along the transportation direction and fed into the miniature valve device, the gas flows unidirectionally in the at least two perforations and the at least two chambers of the gas collecting plate, and the at least two perforations and the at least two chambers of the gas outlet plate, wherein the valve opening of the valve film is opened or closed in response to the unidirectional flow of the gas to perform a pressurizing operation and a pressure-releasing operation selectively.
