The air inlet groove 414 is concavely formed from the second surface 412 and is adjacent to the laser installation region 413. The air inlet groove 414 has an air inlet port 414a communicating with the outside of the base 41 and corresponding to the air inlet frame opening 461a of the cover 46, and two sidewalls passing through a light-transmitting window 414b and communicating with the laser installation region 413.

As shown in fig. 6A and 6B, the piezoelectric actuator 42 includes a vent plate 421, a cavity frame 422, an actuator 423, an insulating frame 424, and a conductive frame 425. The air hole plate 421 is made of a flexible material, and includes a suspension plate 4210 and a hollow hole 4211. The suspension plate 4210 is a plate-shaped structure capable of bending and vibrating, and the shape and size of the suspension plate 4210 approximately correspond to the inner edge of the air guide assembly carrying area 415, but not limited thereto, and the shape of the suspension plate 4210 may be one of square, circle, ellipse, triangle and polygon; the hollow hole 4211 penetrates the center of the suspension plate 4210 to allow gas to flow.

The cavity frame 422 is stacked on the air injection hole plate 421, and the shape thereof corresponds to the air injection hole plate 421. The actuating body 423 is stacked on the cavity frame 422, and defines a resonant cavity 426 with the cavity frame 422 and the suspension plate 4210. An insulating frame 424 is stacked on the actuating body 423 and has an appearance similar to that of the chamber frame 422. The conductive frame 425 is stacked on the insulating frame 424, and has an appearance similar to the insulating frame 424, and the conductive frame 425 has a conductive pin 4251 and a conductive electrode 4252, the conductive pin 4251 extends outward from the outer edge of the conductive frame 425, and the conductive electrode 4252 extends inward from the inner edge of the conductive frame 425. In addition, the actuator 423 further includes a piezoelectric carrier 4231, an adjusting resonator 4232 and a piezoelectric plate 4233. The piezoelectric carrier plate 4231 is supported and stacked on the cavity frame 422. The tuning resonator plate 4232 is supported and stacked on the piezoelectric carrier plate 4231. The piezoelectric plate 4233 bears and is superposed on the tuning resonator plate 4232. The tuning resonator plate 4232 and the piezoelectric plate 4233 are accommodated in the insulating frame 424, and are electrically connected to the piezoelectric plate 4233 via the conductive electrode 4252 of the conductive frame 425. The piezoelectric carrier 4231 and the tuning resonator plate 4232 are made of conductive materials, the piezoelectric carrier 4231 has a piezoelectric pin 4234, the piezoelectric pin 4234 and the conductive pin 4251 are connected to a driving circuit (not shown) on the driving circuit board 43 to receive a driving signal (driving frequency and driving voltage), the driving signal forms a loop by the piezoelectric pin 4234, the piezoelectric carrier 4231, the tuning resonator plate 4232, the piezoelectric plate 4233, the conductive electrode 4252, the conductive frame 425 and the conductive pin 4251, and the insulating frame 424 separates the conductive frame 425 and the actuator 423 to avoid short circuit, so that the driving signal is transmitted to the piezoelectric plate 4233. After receiving the driving signal (driving frequency and driving voltage), the piezoelectric plate 4233 deforms due to the piezoelectric effect, thereby further driving the piezoelectric carrier plate 4231 and adjusting the resonator plate 4232 to generate reciprocating bending vibration.

As described above, the tuning resonator plate 4232 is located between the piezoelectric plate 4233 and the piezoelectric carrier plate 4231, and serves as a buffer between the two, thereby tuning the vibration frequency of the piezoelectric carrier plate 4231. Basically, the thickness of the tuning resonance plate 4232 is larger than the thickness of the piezoelectric carrier plate 4231, and the thickness of the tuning resonance plate 4232 is varied, thereby tuning the vibration frequency of the actuating body 423.

As shown in fig. 6A, fig. 6B and fig. 7A, the air injection hole plate 421, the cavity frame 422, the actuating body 423, the insulating frame 424 and the conductive frame 425 are stacked and positioned in the air guide device supporting region 415, so that the piezoelectric actuator 42 is supported and positioned in the air guide device supporting region 415, and is supported and positioned by the positioning bump 415B, and thus the piezoelectric actuator 42 defines a gap 4212 between the suspension plate 4210 and the inner edge of the air guide device supporting region 415 for air circulation.

Referring to fig. 7A, an airflow chamber 427 is formed between the air injection hole 421 and the bottom of the air guide supporting region 415. The gas flow chamber 427 communicates with the resonance chamber 426 among the actuating body 423, the cavity frame 422 and the floating plate 4210 through the hollow holes 4211 of the gas injection hole plate 421, and the resonance chamber 426 and the floating plate 4210 generate a Helmholtz resonance effect (Helmholtz resonance) by controlling the vibration frequency of the gas in the resonance chamber 426 to be approximately the same as the vibration frequency of the floating plate 4210, so that the gas transmission efficiency is improved.

Fig. 7B and 7C are schematic diagrams illustrating the operation of the piezoelectric actuator of fig. 7A, please refer to fig. 7B, when the piezoelectric plate 4233 moves away from the bottom surface of the air guide assembly supporting area 415, the piezoelectric plate 4233 drives the suspension plate 4210 of the air injection hole plate 421 to move away from the bottom surface of the air guide assembly supporting area 415, so that the volume of the air flow chamber 427 is expanded sharply, the internal pressure thereof decreases to form a negative pressure, and the air outside the piezoelectric actuator 42 is sucked to flow in from the plurality of gaps 4212 and enter the resonant chamber 426 through the hollow hole 4211, so that the air pressure in the resonant chamber 426 increases to generate a pressure gradient; as shown in fig. 7C, when the piezoelectric plate 4233 drives the suspension plate 4210 of the gas injection hole plate 421 to move toward the bottom surface of the gas guide module bearing area 415, the gas in the resonance chamber 426 flows out rapidly through the hollow hole 4211, and the gas in the gas flow chamber 427 is squeezed, so that the converged gas is rapidly and massively injected into the vent holes 415a of the gas guide module bearing area 415 in a state close to the ideal gas state of bernoulli's law. Therefore, by repeating the operations of fig. 7B and 7C, the piezoelectric plate 4233 is vibrated in a reciprocating manner, and the gas pressure inside the exhausted resonant chamber 426 lower than the equilibrium pressure leads the gas to enter the resonant chamber 426 again according to the principle of inertia, so that the vibration frequency of the gas in the resonant chamber 426 is controlled to be approximately the same as the vibration frequency of the piezoelectric plate 4233, thereby generating the helmholtz resonance effect, and realizing high-speed and large-volume transmission of the gas.

Referring to fig. 8A to 8C, which are schematic gas paths of the gas detecting module structure 4, first, as shown in fig. 8A, gas enters from the inlet frame port 461a of the cover 46, enters the inlet channel 414 of the base 41 through the inlet port 414a, and flows to the position of the particle sensor 45. As shown in fig. 8B, the piezoelectric actuator 42 continuously drives the gas sucking the gas inlet path to facilitate rapid introduction and stable circulation of the external gas, and the external gas passes through the upper portion of the particle sensor 45, at this time, the laser element 44 emits a light beam into the gas inlet channel 414 through the light-transmitting window 414B, the gas inlet channel 414 is irradiated with the aerosol contained in the gas above the particle sensor 45, the light beam is scattered and generates a projected light spot when contacting the aerosol, the particle sensor 45 receives the projected light spot generated by scattering and performs calculation to obtain information related to the particle size and concentration of the aerosol contained in the gas, and the gas above the particle sensor 45 is continuously driven by the piezoelectric actuator 42 to be introduced into the vent 415a of the gas guide element bearing area 415 and enter the first area 416B of the gas outlet channel 416.
