Claim 15:
16. The gas detection purification device according to claim 12, wherein the piezoelectric actuator comprises:
a gas-injection plate comprising a suspension plate and a hollow aperture, wherein the suspension plate is permitted to undergo a bending deformation, and the hollow aperture is 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 for being driven in response to an applied voltage to undergo the bending deformation in a reciprocating manner, wherein the actuator element comprises:
a piezoelectric carrying plate carried and stacked on the chamber frame;
an adjusting resonance plate carried and stacked on the piezoelectric carrying plate; and
a piezoelectric plate carried and stacked on the adjusting resonance plate, wherein the piezoelectric plate is configured to drive the piezoelectric carrying plate and the adjusting resonance plate to generate the bending deformation in the reciprocating manner by the applied voltage;
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 four positioning protrusions of the gas-guiding-component loading region for supporting and positioning, so that the gas-injection plate and an inner edge of the gas-guiding-component loading region define a vacant space for gas flowing, a flowing chamber is formed between the gas-injection plate and the bottom surface of the gas-guiding-component loading region, a resonance chamber is formed among the actuator element, the chamber frame and the suspension plate, wherein when the actuator element is enabled to drive the gas-injection plate to move in resonance, the suspension plate of the gas-injection plate is driven to generate the bending deformation in a reciprocating manner, the gas is inhaled through the vacant space, flows into the flowing chamber, and is discharged out, so as to achieve gas transportation.
