In the embodiment, the piezoelectric actuator 322 includes a gas-injection plate 3221, a chamber frame 3222, an actuator element 3223, an insulation frame 3224 and a conductive frame 3225. In the embodiment, the gas-injection plate 3221 is made by a flexible material and includes a suspension plate 3221a and a hollow aperture 3221b. The suspension plate 3221a is a sheet structure and is permitted to undergo a bending deformation. Preferably but not exclusively, the shape and the size of the suspension plate 3221a are accommodated in the inner edge of the gas-guiding-component loading region 3215, but not limited thereto. The hollow aperture 3221b passes through a center of the suspension plate 3221a, so as to allow the gas to flow therethrough. Preferably but not exclusively, in the embodiment, the shape of the suspension plate 3221a is selected from the group consisting of a square, a circle, an ellipse, a triangle and a polygon, but not limited thereto.

In the embodiment, the chamber frame 3222 is carried and stacked on the gas-injection plate 3221. In addition, the shape of the chamber frame 3222 is corresponding to the gas-injection plate 3221. The actuator element 3223 is carried and stacked on the chamber frame 3222. A resonance chamber 3226 is collaboratively defined by the actuator element 3223, the chamber frame 3222 and the suspension plate 3221a and is formed between the actuator element 3223, the chamber frame 3222 and the suspension plate 3221a. The insulation frame 3224 is carried and stacked on the actuator element 3223 and the appearance of the insulation frame 3224 is similar to that of the chamber frame 3222. The conductive frame 3225 is carried and stacked on the insulation frame 3224, and the appearance of the conductive frame 3225 is similar to that of the insulation frame 3224. In addition, the conductive frame 3225 includes a conducting pin 3225a and a conducting electrode 3225b. The conducting pin 3225a is extended outwardly from an outer edge of the conductive frame 3225, and the conducting electrode 3225b is extended inwardly from an inner edge of the conductive frame 3225. Moreover, the actuator element 3223 further includes a piezoelectric carrying plate 3223a, an adjusting resonance plate 3223b and a piezoelectric plate 3223c.

The piezoelectric plate 3223c is carried and stacked on the adjusting resonance plate 3223b. The adjusting resonance plate 3223b and the piezoelectric plate 3223c are accommodated in the insulation frame 3224. The conducting electrode 3225b of the conductive frame 3225 is electrically connected to the piezoelectric plate 3223c. In the embodiment, the piezoelectric carrying plate 3223a and the adjusting resonance plate 3223b are made by a conductive material. The piezoelectric carrying plate 3223a includes a piezoelectric pin 3223d. The piezoelectric pin 3223d and the conducting pin 3225a are electrically connected to a driving circuit (not shown) of the driving circuit board 323, so as to receive a driving signal, such as a driving frequency and a driving voltage. Through this structure, a circuit is formed by the piezoelectric pin 3223d, the piezoelectric carrying plate 3223a, the adjusting resonance plate 3223b, the piezoelectric plate 3223c, the conducting electrode 3225b, the conductive frame 3225 and the conducting pin 3225a for transmitting the driving signal. Moreover, the insulation frame 3224 is insulated between the conductive frame 3225 and the actuator element 3223, so as to avoid the occurrence of a short circuit. Thereby, the driving signal is transmitted to the piezoelectric plate 3223c. After receiving the driving signal such as the driving frequency and the driving voltage, the piezoelectric plate 3223c deforms due to the piezoelectric effect, and the piezoelectric carrying plate 3223a and the adjusting resonance plate 3223b are further driven to generate the bending deformation in the reciprocating manner.

Furthermore, in the embodiment, the adjusting resonance plate 3223b is located between the piezoelectric plate 3223c and the piezoelectric carrying plate 3223a and served as a cushion between the piezoelectric plate 3223c and the piezoelectric carrying plate 3223a. Thereby, the vibration frequency of the piezoelectric carrying plate 3223a is adjustable. Basically, the thickness of the adjusting resonance plate 3223b is greater than the thickness of the piezoelectric carrying plate 3223a, and the vibration frequency of the actuator element 3223 can be adjusted by adjusting the thickness of the adjusting resonance plate 3223b.

Please refer to FIG. 7A, FIG. 7B, FIG. 8A, FIG. 8B and FIG. 9A. In the embodiment, the gas-injection plate 3221, the chamber frame 3222, the actuator element 3223, the insulation frame 3224 and the conductive frame 3225 are stacked and positioned in the gas-guiding-component loading region 3215 sequentially, so that the piezoelectric actuator 322 is supported and positioned in the gas-guiding-component loading region 3215. A plurality of clearances 3221c are defined between the suspension plate 3221a of the gas-injection plate 3221 and an inner edge of the gas-guiding-component loading region 3215 for gas flowing therethrough. In the embodiment, a flowing chamber 3227 is formed between the gas-injection plate 3221 and the bottom surface of the gas-guiding-component loading region 3215. The flowing chamber 3227 is in communication with the resonance chamber 3226 between the actuator element 3223, the chamber frame 3222 and the suspension plate 3221a through the hollow aperture 3221b of the gas-injection plate 3221. By controlling the vibration frequency of the gas in the resonance chamber 3226 to be close to the vibration frequency of the suspension plate 3221a, the Helmholtz resonance effect is generated between the resonance chamber 3226 and the suspension plate 3221a, so as to improve the efficiency of gas transportation. When the piezoelectric plate 3223c is moved away from the bottom surface of the gas-guiding-component loading region 3215, the suspension plate 3221a of the gas-injection plate 3221 is driven to move away from the bottom surface of the gas-guiding-component loading region 3215 by the piezoelectric plate 3223c. In that, the volume of the flowing chamber 3227 is expanded rapidly, the internal pressure of the flowing chamber 3227 is decreased to form a negative pressure, and the gas outside the piezoelectric actuator 322 is inhaled through the clearances 3221c and enters the resonance chamber 3226 through the hollow aperture 3221b. Consequently, the pressure in the resonance chamber 3226 is increased to generate a pressure gradient. When the suspension plate 3221a of the gas-injection plate 3221 is driven by the piezoelectric plate 3223c to move toward the bottom surface of the gas-guiding-component loading region 3215, the gas in the resonance chamber 3226 is discharged out rapidly through the hollow aperture 3221b, and the gas in the flowing chamber 3227 is compressed, thereby the converged gas is rapidly and massively ejected out of the flowing chamber 3227 under the condition close to an ideal gas state of the Benulli's law, and transported to the ventilation hole 3215a of the gas-guiding-component loading region 3215.

By repeating the above operation steps shown in FIG. 9B and FIG. 9C, the piezoelectric plate 3223c is driven to generate the bending deformation in a reciprocating manner. According to the principle of inertia, since the gas pressure inside the resonance chamber 3226 is lower than the equilibrium gas pressure after the converged gas is ejected out, the gas is introduced into the resonance chamber 3226 again. Moreover, the vibration frequency of the gas in the resonance chamber 3226 is controlled to be close to the vibration frequency of the piezoelectric plate 3223c, so as to generate the Helmholtz resonance effect to achieve the gas transportation at high speed and in large quantities. The gas is inhaled through the inlet opening 3261a of the outer cover 326, flows into the gas-inlet groove 3214 of the base 321 through the gas-inlet 3214a, and is transported to the position of the particulate sensor 325. The piezoelectric actuator 322 is enabled continuously to inhale the gas into the inlet path, and facilitate the gas outside the gas detection device to be introduced rapidly, flow stably, and transported above the particulate sensor 325. At this time, a projecting light beam emitted from the laser component 324 passes through the transparent window 3214b to irritate the suspended particles contained in the gas flowing above the particulate sensor 325 in the gas-inlet groove 3214. When the suspended particles contained in the gas are irradiated and generate scattered light spots, the scattered light spots are received and calculated by the particulate sensor 325 for obtaining related information about the sizes and the concentration of the suspended particles contained in the gas. Moreover, the gas above the particulate sensor 325 is continuously driven and transported by the piezoelectric actuator 322, flows into the ventilation hole 3215a of the gas-guiding-component loading region 3215, and is transported to the gas-outlet groove 3216. At last, after the gas flows into the gas outlet groove 3216, the gas is continuously transported into the gas-outlet groove 3216 by the piezoelectric actuator 322, and thus the gas in the gas-outlet groove 3216 is pushed to discharge through the gas-outlet 3216a and the outlet opening 3261b.
