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.

a primary gas pump and at least one secondary gas pump, wherein the primary gas pump is disposed in the protruding frame of the flow-guiding pedestal, and the secondary gas pump is disposed in the chamber frame of the flow-guiding pedestal, wherein the length of the recess is smaller than a length of the secondary pump, and the secondary pump seals the periphery of the recess; and
at least one adhesive film having a hollow structure and disposed between the primary gas pump and the flow-guiding pedestal, wherein the hollow structure defines a convergence chamber in communication with the communicating aperture,
wherein the gas outlet cover covers and seals the flow-guiding pedestal so as to be connected to the protruding frame of the flow-guiding pedestal, wherein while the primary gas pump and the secondary gas pump are enabled to transport gas simultaneously, the gas is introduced into the recess of the flow-guiding pedestal, is transported to the primary gas pump through the communicating aperture and the convergence chamber sequentially, is transported to the gas outlet cavity via the primary gas pump, and finally is discharged out from the gas outlet nozzle.

2. The gas transportation device according to claim 1 , wherein the gas outlet nozzle is in a conical shape having a larger end and a smaller end that the gas outlet nozzle is gradually tapered from the larger end to the smaller end, and has interior diameters gradually decreased from the larger end to the smaller end.

3. The gas transportation device according to claim 1 , wherein the protruding frame protrudes above and is arranged around a periphery of the main plate, the chamber frame protrudes below and is arranged around the periphery of the main plate, and a side length of the protruding frame is smaller than a side length of the chamber frame so that a stepped structure is formed, whereby the gas outlet cover is engaged with the stepped structure and disposed on the flow-guiding pedestal.

4. The gas transportation device according to claim 1 , wherein the flow-guiding pedestal has an adhesive-injecting opening and a pin opening.
