Claim 10:
11. The gas detection purification device according to claim 10, wherein the piezoelectric actuator comprises:
a suspension plate being square-shaped and being permitted to undergo a bending vibration;
an outer frame surrounding the suspension plate;
at least one bracket connected between the suspension plate and the outer frame to provide an elastic support for the suspension plate, wherein a surface of the suspension plate and a surface of the outer frame are non-coplanar, and a chamber space is formed between a surface of the suspension plate and the resonance plate, and
a piezoelectric element having a side, wherein a length of the side of the piezoelectric element is less than or equal to that of the suspension plate, and the piezoelectric element is attached on a surface of the suspension plate, wherein when a voltage is applied to the piezoelectric element, the suspension plate is driven to undergo the bending vibration.
