Abstract: A fluid transportation device includes a valve body, a valve membrane, a valve chamber seat, an actuator and an outer sleeve. The valve body includes an inlet passage and an outlet passage. The valve chamber seat includes an inlet valve channel, an outlet valve channel and a pressure chamber. The pressure chamber is in communication with the inlet valve channel and the outlet valve channel. The valve membrane is arranged between the valve body and the valve chamber seat. The valve membrane includes two valve plates. The inlet valve channel and the outlet valve channel are closed by the two valve plates. The pressure chamber is covered by the actuator. The outer sleeve has an accommodation space. A ring-shaped protrusion structure is formed on the inner wall of the outer sleeve. Moreover, plural engaging structures are discretely arranged on a periphery of the outer sleeve.

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 piezoelectric actuator includes a suspension plate, an outer frame, at least one bracket and a piezoelectric ceramic plate. The suspension plate is a square structure. The length of the suspension plate is in a range between 4 mm and 8 mm, and the suspension plate is permitted to undergo a curvy vibration from a middle portion to a periphery portion. The outer frame is arranged around the suspension plate. The at least one bracket is connected between the suspension plate and the outer frame for elastically supporting the suspension plate. The piezoelectric ceramic plate is a square structure and has a length not larger than a length of the suspension plate. The piezoelectric ceramic plate is attached on a first surface of the suspension plate. When a voltage is applied to the piezoelectric ceramic plate, the suspension plate is driven to undergo the curvy vibration.

Abstract: A piezoelectric actuator includes a square suspension plate, an outer frame, plural brackets and a square piezoelectric ceramic plate. The outer frame is arranged around the suspension plate. A second surface of the outer frame and a second surface of the suspension plate are coplanar with each other. The plural brackets are perpendicularly connected between the suspension plate and the outer frame for elastically supporting the suspension plate. Each bracket has a length in a range between 1.11 mm and 1.21 mm and a width in a range between 0.2 mm and 0.6 mm. A length of the piezoelectric ceramic plate is not larger than a length of the suspension plate. The piezoelectric ceramic plate is attached on a first surface of the suspension plate.

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.
