Abstract

A gas transportation device includes a gas outlet cover, plural flow-guiding pedestals and plural gas pumps. The gas outlet cover includes a gas outlet nozzle and a gas outlet cavity. The gas outlet nozzle and the gas outlet cavity are in communication with each other. 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 in communication with the recess. The gas pumps are disposed inside the chamber frames of the flow-guiding pedestals, respectively. The gas outlet cover covers the flow-guiding pedestals and is connected to the protruding frames, whereby plural convergence chambers are defined and are in communication with the gas outlet cavity. Consequently, the gas is transported through the recesses, the communicating apertures, the convergence chambers and the gas outlet cavity sequentially, and finally is discharged out from the gas outlet nozzle.

First claim

What is claimed is:

1. A gas transportation device, comprising:
a gas outlet cover comprising a gas outlet nozzle and a gas outlet cavity, wherein the gas outlet nozzle and the gas outlet cavity are in communication with and spatially corresponding to each other;
plural flow-guiding pedestals, each of which has a main plate, a protruding frame and a chamber frame, wherein the main plate has a recess and a communicating aperture in communication with the recess; and
plural gas pumps disposed inside the chamber frames of the plural flow-guiding pedestals, respectively,
wherein the plural flow-guiding pedestals are arranged side by side, the gas outlet cover covers and seals the flow-guiding pedestals and is closely connected to the protruding frames of the plural flow-guiding pedestals, whereby plural convergence chambers are defined and are in communication with the gas outlet cavity, and while the gas pumps are enabled to transport gas, the gas is transported through the recesses, the communicating apertures, the convergence chambers and the gas outlet cavity sequentially, 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, a side length of the protruding frame is smaller than a side length of the chamber frame, and a stepped structure is formed so that 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 protruding frame has an adhesive-injecting opening, and the chamber frame has a pin opening.

5. The gas transportation device according to claim 1 , wherein each of the plural gas pumps comprises:
a gas inlet plate having at least one inlet, at least one convergence channel and a convergence cavity;
a resonance plate having a central aperture;
a piezoelectric actuator comprising a piezoelectric element, a suspension plate, an outer frame, at least one bracket and a first conducting pin, wherein at least one vacant space is defined among the suspension plate, the outer frame and the at least one bracket, the suspension plate has a first surface and a second surface, a bulge is disposed on the second surface, and the piezoelectric element is attached on the first surface;
a first insulation plate;
a conducting plate comprising a second conducting pin; and
a second insulation plate,
wherein the gas inlet plate, the resonance plate, the piezoelectric actuator, the first insulation plate, the conducting plate and the second insulation plate are stacked sequentially, and a compressing chamber is defined by a gap between the resonance plate and the piezoelectric actuator, wherein in response to an applied voltage, the piezoelectric element drives the suspension plate to bend and vibrate in a vertical direction in a reciprocating manner, whereby the gas is fed through the at least one inlet and is transported to the compressing chamber through the convergence channel, the convergence cavity and the central aperture sequentially, and finally is directed to the recess through the at least one vacant space.

6. A gas transportation device, comprising:
at least one gas outlet cover comprising at least one gas outlet nozzle and at least one gas outlet cavity, wherein the gas outlet nozzle and the gas outlet cavity are in communication with and spatially corresponding to each other;
plural flow-guiding pedestals, each of which has at least one main plate, at least one protruding frame and at least one chamber frame, wherein the main plate has at least one recess and at least one communicating aperture in communication with the recess; and
plural gas pumps disposed inside the chamber frames of the plural flow-guiding pedestals, respectively,
wherein the plural flow-guiding pedestals are arranged side by side, the gas outlet cover covers and seals the flow-guiding pedestals and is closely connected to the protruding frames of the plural flow-guiding pedestals, whereby at least one convergence chamber is defined and is in communication with the gas outlet cavity, and while the gas pumps are enabled to transport gas, the gas is transported through the recesses, the communicating apertures, the convergence chamber and the gas outlet cavity sequentially, and finally is discharged out from the gas outlet nozzle.
