Claim 16:
17. The home device capable of gas detection according to claim 12, wherein the piezoelectric actuator comprises:
a gas-injection plate comprising a plurality of connecting elements, a suspension plate and a hollow aperture, wherein the suspension plate is permitted to undergo a bending deformation, the plurality of connecting elements are adjacent to a periphery of the suspension plate, and the hollow aperture is formed at a center of the suspension plate, wherein the suspension plate is fixed through the plurality of connecting elements, and the plurality of connecting elements are configured for elastically supporting the suspension plate, wherein a flowing chamber is formed between the gas-injection plate and the bottom surface of the gas-guiding-component loading region, and at least one clearance is formed among the plurality of connecting components and 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, comprising:
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 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 and result 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 clearance, flowed into the flowing chamber, and discharged out, so as to achieve gas transportation.
