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 nozzle plate includes at least one bracket, a suspension plate and a through hole. The bracket includes a fixing part and a connecting part. A shape of the fixing part matches a shape of the fixing recess. The nozzle plate is accommodated within the accommodation space. A resonance chamber is defined by the actuator, the chamber frame and the suspension plate collaboratively. When the actuator is enabled, the nozzle plate is subjected to resonance and the suspension plate of the nozzle plate vibrates in the reciprocating manner. Consequently, the gas is transported to a gas-guiding chamber through the at least one vacant space and outputted from the discharging opening, thereby achieving the gas transportation and circulation.
