Miniature fluid control device
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.
