    Abstract: A gas transportation device includes a casing, a nozzle plate, a chamber frame, an actuator, an insulating frame and a conducting frame, which are stacked sequentially. A cuboidal resonance chamber is defined by the actuator, the chamber frame and a suspension plate of the nozzle plate collaboratively. When the actuator is driven, the nozzle plate is subjected to a resonance and the suspension plate of the nozzle plate vibrates in the reciprocating manner. Consequently, the gas is transported to a gas-guiding chamber through at least one interspace and discharged from the discharging opening so as to implement the gas circulation.

    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. After a gas is fed into the gas inlet plate, the gas is transferred to the first chamber through the resonance plate and then transferred downwardly. Consequently, a pressure gradient is generated to continuously push the gas. The miniature valve device includes a valve plate and a gas outlet plate. After the gas is transferred from the miniature fluid control device to the miniature valve device, the valve opening of the valve plate is correspondingly opened or closed and the gas is transferred in one direction. Consequently, a pressure-collecting operation or a pressure-releasing operation is selectively performed.

    Abstract: A gas transportation device includes a casing, a nozzle plate, a chamber frame, an actuator, an insulating frame and a conducting frame, which are stacked sequentially. The casing has a conduit protruding outwardly from the casing and aligned with a discharging opening. The conduit has a guiding channel and an outlet. The guiding channel has a cone shape and is tapered from an end proximate to the discharging opening to the other end proximate to the outlet. The actuator, the chamber frame and the suspension plate collaboratively define a resonance chamber. When the actuator is driven, the nozzle plate is subjected to resonance and the suspension plate of the nozzle plate vibrates in a reciprocating manner. Consequently, the gas is transported to a gas-guiding chamber through at least one gap and outputted from the discharging opening.

    Abstract: A miniature fluid control device includes a piezoelectric actuator, a gas collecting plate and a base. The piezoelectric actuator includes a suspension plate, an outer frame, at least one bracket and a piezoelectric ceramic plate. The suspension plate is a square plate. The outer frame is arranged around the suspension plate. A surface of the outer frame and a surface of the suspension plate are coplanar with each other. The gas collecting plate is a frame body with an accommodation space. The base includes a gas inlet plate and a resonance plate. The base is disposed within the accommodation space to seal the piezoelectric actuator. An adhesive layer is arranged between the second surface of the outer frame of the piezoelectric actuator and the resonance plate. Consequently, a depth of a compressible chamber between the piezoelectric actuator and the resonance plate is maintained.

    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. The gas collecting plate has a length in a range between 6 mm and 18 mm and a width in a range between 6 mm and 18 mm. A gap is formed between the resonance plate and the piezoelectric actuator to define a first chamber. When the piezoelectric actuator is driven and after the gas is fed into the gas inlet plate, the gas is transferred to the first chamber through the resonance plate and then transferred downwardly. The miniature valve device comprises a valve plate and a gas outlet plate. The gas is transferred from the miniature fluid control device to the miniature valve device so as to perform pressure-collecting operation or pressure-releasing operation.
