Claim 18:
19. The gas exchange device according to claim 18, wherein the piezoelectric actuator comprises:
a gas-injection plate comprising a suspension plate capable of bending and vibrating and a hollow aperture formed at a center of the suspension plate;
a chamber frame carried and stacked on the suspension plate;
an actuator element carried and stacked on the chamber frame and comprising a piezoelectric carrying plate, an adjusting resonance plate and a piezoelectric plate, wherein the piezoelectric carrying plate is carried and stacked on the chamber frame, the adjusting resonance plate is carried and stacked on the piezoelectric carrying plate, and the piezoelectric plate is carried and stacked on the adjusting resonance plate, and after receiving a voltage, the piezoelectric carrying plate and the adjusting resonance plate are driven to bend and vibrate in a reciprocating manner;
an insulation frame carried and stacked on the actuator element; and
a conductive frame carried and stacked on the insulation frame;
wherein the gas-injection plate is fixed on the gas-guiding-component loading region, so that a vacant space surrounding the gas-injection plate is defined for flowing the gas therethrough, a flowing chamber is formed between the gas-injection plate and the bottom surface of the gas-guiding-component loading region, and a resonance chamber is collaboratively defined by the actuator element, the chamber frame and the suspension plate, thereby through driving the actuator element to drive the gas-injection plate to resonate, the suspension plate of the gas-injection plate generates vibration and displacement in a reciprocating manner, so as to inhale the gas into the flowing chamber through the vacant space and then eject out for completing a gas flow transmission.
