Patent ID: 10975856

Abstract:
A gas transportation device is provided and includes a plurality of flow guiding units. Each of the flow guiding units includes an inlet plate, a substrate, a resonance plate, an actuating plate, a piezoelectric component, an outlet plate and a valve, which are sequentially stacked. A convergence chamber is formed between the resonance plate and the inlet plate. The actuating plate has a suspension part, an outer frame and a plurality of interspaces. The piezoelectric component is attached on a surface of the suspension part. Gas is inhaled into the convergence chamber via an inlet aperture of the inlet plate, is transported into a first chamber via a central aperture of the resonance plate, is further transported into a second chamber via the interspaces, and is discharged out from an outlet aperture of the outlet plate. The gas is transported by the flow guiding units disposed in a specific arrangement.
