  • Patent number: 10487821
    Abstract: A miniature fluid control device includes a piezoelectric actuator and a housing. The piezoelectric actuator comprises a suspension plate, an outer frame, at least one bracket and a piezoelectric ceramic plate. The piezoelectric ceramic plate is attached on a first surface of the suspension plate and has a length not larger than that of the suspension plate. The housing includes a gas collecting plate and a base. The gas collecting plate is a frame body with a sidewall and comprises a plurality of perforations. The base seals a bottom of the piezoelectric actuator and has a central aperture corresponding to the middle portion of the suspension plate. When the voltage is applied to the piezoelectric actuator, the suspension plate is permitted to undergo the curvy vibration, the fluid is transferred from the central aperture of the base to the gas-collecting chamber, and exited from the perforations.

  • Patent number: 10487820
    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.
