[0022] In the embodiment, the laser component 624, the particulate sensor 625 and the gas sensor 627 are disposed on and electrically connected to the driving circuit board 623 and located within the base 621. In order to clearly describe and illustrate the positions of the laser component 624 and the particulate sensor 625 in the base 621, the driving circuit board 623 is intentionally omitted. The laser component 624 is accommodated in the laser loading region 6211 of the base 621, and the particulate sensor 625 is accommodated in the gas-inlet groove 6212 of the base 621 and is aligned to the laser component 624. In addition, the laser component 624 is spatially corresponding to the transparent window 6216, therefore, a light beam emitted by the laser component 624 passes through the transparent window 6216 and is irradiated into the gas-inlet groove 6212.

In the embodiment, a projecting light beam emitted from the laser component 624 passes through the transparent window 6216 and enters the gas-inlet groove 6212 to irradiate the suspended particles contained in the gas passing through the gas-inlet groove 6212. 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 625 in the orthogonal direction to obtain the gas detection data. Notably, the laser component 624 emits a parallel light source, and the parallel light source passes through the transparent window 6216.

[0023] In the embodiment, the gas sensor 627 is positioned and accommodated in the gas-outlet groove 6214, so as to detect the air pollution introduced into the gas-outlet groove 6214.

In addition, the gas-guiding-component loading region 6213 of the base 621 is in fluid communication with the gas-inlet groove 6212. When the driving circuit board 623 is covered inside the base 621 and the outer cover 626 is covered outside the base 621, the inlet opening 6262 corresponds to the gas-inlet 6215 of the base 621 to collaboratively define an inlet path, and the outlet opening 6263 corresponds to the gas-outlet 6218 of the base 621 to collaboratively define an air outlet path. When the piezoelectric actuator 622 is enabled, the gas in the gas-inlet groove 6212 is inhaled by the piezoelectric actuator 622, so that the gas flows into the piezoelectric actuator 622, and is transported into the gas-outlet groove 6214 through the ventilation hole 6217 of the gas-guiding-component loading region 6213. Finally, when the gas enters the gas-outlet groove 6214, the piezoelectric actuator 622 continuously transports the gas from the gas inlet path into the gas-outlet groove 6214, and the gas in the gas-outlet groove 6214 is pushed to the gas outlet path and through the gas-outlet 6218 and the outlet opening 6263 to discharge to the outside, to achieve the gas transportation at high speed and in large quantities.

The piezoelectric pin 6223d and the conducting pin 6225a are electrically connected to a driving circuit (not shown) of the driving circuit board 623, 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 6223d, the piezoelectric carrying plate 6223a, the adjusting resonance plate 6223b, the piezoelectric plate 6223c, the conducting electrode 6225b, the conductive frame 6225 and the conducting pin 6225a for transmitting the driving signal. Moreover, the insulation frame 6224 is insulated between the conductive frame 6225 and the actuator element 6223, so as to avoid the occurrence of a short circuit. Thereby, the driving signal is transmitted to the piezoelectric plate 6223c. After receiving the driving signal such as the driving frequency and the driving voltage, the piezoelectric plate 6223c deforms due to the piezoelectric effect, and the piezoelectric carrying plate 6223a and the adjusting resonance plate 6223b are further driven to generate the bending deformation in the reciprocating manner.

[0029] Furthermore, in the embodiment, the adjusting resonance plate 6223b is located between the piezoelectric plate 6223c and the piezoelectric carrying plate 6223a and served as a cushion between the piezoelectric plate 6223c and the piezoelectric carrying plate 6223a. Thereby, the vibration frequency of the piezoelectric carrying plate 6223a is adjustable. Basically, the thickness of the adjusting resonance plate 6223b is greater than the thickness of the piezoelectric carrying plate 6223a, and the vibration frequency of the actuator element 6223 can be adjusted by adjusting the thickness of the adjusting resonance plate 6223b. In the embodiment, the gas-injection plate 6221, the chamber frame 6222, the actuator element 6223, the insulation frame 6224 and the conductive frame 6225 are stacked and positioned in the gas-guiding-component loading region 6213 sequentially, so that the piezoelectric actuator 622 is supported and positioned in the gas-guiding-component loading region 6213. A plurality of clearances 6221c are defined between the suspension plate 6221a of the gas-injection plate 6221 and an inner edge of the gas-guiding-component loading region 6213 for gas flowing therethrough.

[0030] In the embodiment, a flowing chamber 6227 is formed between the gas-injection plate 6221 and the bottom surface of the gas-guiding-component loading region 6213. The flowing chamber 6227 is in communication with the resonance chamber 6226 between the actuator element 6223, the chamber frame 6222 and the suspension plate 6221a. By controlling the vibration frequency of the gas in the resonance chamber 6226 to be close to the vibration frequency of the suspension plate 6221a, the Helmholtz resonance effect is generated between the resonance chamber 6226 and the suspension plate 6221a, so as to improve the efficiency of gas transportation. When the piezoelectric plate 6223c is moved away from the bottom surface of the gas-guiding-component loading region 6213, the suspension plate 6221a of the gas-injection plate 6221 is driven to move away from the bottom surface of the gas-guiding-component loading region 6213 by the piezoelectric plate 6223c. In that, the volume of the flowing chamber 6227 is expanded rapidly, the internal pressure of the flowing chamber 6227 is decreased to form a negative pressure, and the gas outside the piezoelectric actuator 622 is inhaled through the clearances 6221c and enters the resonance chamber 6226 through the hollow aperture 6221b. Consequently, the pressure in the resonance chamber 6226 is increased to generate a pressure gradient. When the suspension plate 6221a of the gas-injection plate 6221 is driven by the piezoelectric plate 6223c to move toward the bottom surface of the gas-guiding-component loading region 6213, the gas in the resonance chamber 6226 is discharged out rapidly through the hollow aperture 6221b, and the gas in the flowing chamber 6227 is compressed, thereby the converged gas is quickly and massively ejected out of the flowing chamber 6227 under the condition close to an ideal gas state of the Benulli's law, and transported to the ventilation hole 6217 of the gas-guiding-component loading region 6213.

[0031] By repeating the above operation steps shown in FIG. 9B and FIG. 9C, the piezoelectric plate 6223c 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 6226 is lower than the equilibrium gas pressure after the converged gas is ejected out, the gas is introduced into the resonance chamber 6226 again. Moreover, the vibration frequency of the gas in the resonance chamber 6226 is controlled to be close to the vibration frequency of the piezoelectric plate 6223c, so as to generate the Helmholtz resonance effect to achieve the gas transportation at high speed and in large quantities.

[0032] Please refer to FIG. 10A to FIG. 10C. The gas is inhaled through the gas-inlet 6262 on the outer cover 626, flows into the gas-inlet groove 6212 of the base 621 through the gas-inlet 6215, and is transported to the position of the particulate sensor 625. In addition, the piezoelectric actuator 622 is enabled continuously to inhale the gas into the inlet path, and facilitate the gas outside the gas detection module to be introduced rapidly, flow stably, and transported above the particulate sensor 625. At this time, a projecting light beam emitted from the laser component 624 passes through the transparent window 6216 to irritate the suspended particles contained in the gas flowing above the particulate sensor 625 in the gas-inlet groove 6212. 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 625 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 625 is continuously driven and transported by the piezoelectric actuator 622, flows into the ventilation hole 6217 of the gas-guiding-component loading region 6213, and is transported to the gas-outlet groove 6214. At last, after the gas flows into the gas outlet groove 6214, the gas is continuously transported into the gas-outlet groove 6214 by the piezoelectric actuator 622, and thus the gas in the gas-outlet groove 6214 is pushed to discharge through the gas-outlet 6218a and the outlet opening 6263, to achieve the gas transportation at high speed and in large quantities.
