Claim 9:
10. The gas detection purification according to claim 9, wherein the actuating pump comprises:
a gas inlet plate having at least one gas inlet aperture, at least one convergence channel, and a convergence chamber, wherein the at least one gas inlet aperture is disposed to inhale the gas, the at least one gas inlet aperture correspondingly penetrates through the at least one convergence channel, and the at least one convergence channel is converged into the convergence chamber, so that the gas inhaled through the at least one gas inlet aperture is converged into the convergence chamber;
a resonance plate disposed on the gas inlet plate and having a central aperture, a movable part and a fixed part, wherein the central aperture is disposed at a center of the resonance plate, and corresponds in position to the convergence chamber of the gas inlet plate, the movable part surrounds the central aperture and corresponds in position to the convergence chamber, and the fixed part surrounds the movable part and is fixedly attached on the gas inlet plate; and
a piezoelectric actuator correspondingly disposed on the resonance plate and comprising:
a first insulation plate;
a conductive plate; and
a second insulation plate
wherein, the gas inlet plate, the resonance plate, the piezoelectric actuator, the first insulation plate, the conductive plate and the second insulation plate are stacked sequentially, and a chamber space is formed between the resonance plate and the piezoelectric actuator, so that when the piezoelectric actuator is driven, the gas introduced from the at least one gas inlet aperture of the gas inlet plate is converged to the convergence chamber through the at least one convergence channel, and flows through the central aperture of the resonance plate so as to produce a resonance by the movable part of the resonance plate and the piezoelectric actuator to transport the gas.
