Patent ID: 10801489

Abstract:
A gas transportation device includes a gas outlet cover, at least one flow-guiding pedestal, a primary gas pump, a secondary gas pump and an adhesive film. The gas outlet cover includes a gas outlet nozzle and a gas outlet cavity. Each flow-guiding pedestal includes a main plate, a protruding frame and a chamber frame. The main plate includes a recess and a communicating aperture. The primary gas pump is disposed in the protruding frame, and the secondary gas pump is disposed in the chamber frame. The adhesive film has a hollow structure, is disposed between the primary gas pump and the flow-guiding pedestal and defines a convergence chamber. Consequently, the gas is introduced into the recess, transported to the primary gas pump through the communicating apertures and the convergence chamber, transported to the gas outlet cavity via the primary gas pump, and finally discharged out from the gas outlet nozzle.
