Abstract
A miniature fluid control device for transporting gas is disclosed, which includes a gas inlet plate, a resonance plate, a piezoelectric actuator and a gas collecting plate stacked on each other. The gas inlet plate includes at least one inlet, at least one convergence channel and a circular cavity which forms a convergence chamber. The resonance plate has a central aperture. The piezoelectric actuator includes a suspension plate, an outer frame and a piezoelectric plate, wherein the suspension plate has a cylindrical bulge aligned with the circular cavity. The ratio of a second diameter of the cylindrical bulge to a first diameter of the circular cavity is set in a specified range to optimize the gas pressure of the transported gas, thus assuring efficiency of gas transmission of the miniature fluid control device.
