Claim 7:
8. The gas detection and cleaning system for the vehicle according to claim 3, 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 a driving voltage to undergo the bending deformation 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 supported and positioned on the four positioning protrusions of the gas-guiding-component loading region, so that the gas-injection plate and an inner edge of the gas-guiding-component loading region define a clearance for gas to flow through, 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 between 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, and the gas is inhaled through the clearance, flowing into the flowing chamber, and discharged out, so as to achieve gas transportation.
