Abstract
A gas transportation device includes a casing, a nozzle plate, a chamber frame, an actuator, an insulating frame and a conducting frame, which are stacked sequentially. The casing has a conduit protruding outwardly from the casing and aligned with a discharging opening. The conduit has a guiding channel and an outlet. The guiding channel has a cone shape and is tapered from an end proximate to the discharging opening to the other end proximate to the outlet. The actuator, the chamber frame and the suspension plate collaboratively define a resonance chamber. When the actuator is driven, the nozzle plate is subjected to resonance and the suspension plate of the nozzle plate vibrates in a reciprocating manner. Consequently, the gas is transported to a gas-guiding chamber through at least one gap and outputted from the discharging opening.
