Continuing to refer to FIGS. 6A and 6B , the piezoelectric actuator 42 described above includes an air injection hole sheet 421 , a cavity frame 422 , an actuator 423 , an insulating frame 424 and a conductive frame 425 . The air jet hole sheet 421 is made of a flexible material, and has a suspension sheet 4210 and a hollow hole 4211 . The suspension piece 4210 is a sheet-like structure that can bend and vibrate, and its shape and size roughly correspond to the inner edge of the air guide element bearing area 415, but not limited to this, the shape of the suspension piece 4210 can also be square, circular, oval , one of triangle and polygon; the hollow hole 4211 runs through the center of the suspension sheet 4210 for gas circulation.

The cavity frame 422 described above is stacked on the air injection hole sheet 421 , and its shape corresponds to the air injection hole sheet 421 . The actuating body 423 is stacked on the cavity frame 422 and defines a resonance chamber 426 between the cavity frame 422 and the suspension plate 4210 . The insulating frame 424 is stacked on the actuating body 423 , and its appearance is similar to the cavity frame 422 . The conductive frame 425 is stacked on the insulating frame 424, and its appearance is similar to that of the insulating frame 424. The conductive frame 425 has a conductive pin 4251 and a conductive electrode 4252. The conductive pin 4251 extends from the outer edge of the conductive frame 425 and conducts electricity. The electrodes 4252 extend inward from the inner edge of the conductive frame 425 . In addition, the actuating body 423 further includes a piezoelectric carrier plate 4231, an adjustment The resonance plate 4232 and a piezoelectric plate 4233. The piezoelectric carrier plate 4231 is supported and stacked on the cavity frame 422 . The adjustment resonance plate 4232 is supported and stacked on the piezoelectric carrier plate 4231 . The piezoelectric plate 4233 is supported and stacked on the adjustment resonance plate 4232 . The adjustment resonance plate 4232 and the piezoelectric plate 4233 are accommodated in the insulating frame 424 , and are electrically connected to the piezoelectric plate 4233 by the conductive electrodes 4252 of the conductive frame 425 . The piezoelectric carrier plate 4231 and the adjustment resonance plate 4232 are all made of conductive materials. The piezoelectric carrier plate 4231 has a piezoelectric pin 4234, and the piezoelectric pin 4234 and the conductive pin 4251 are connected to the driving circuit board 43. The driving circuit (not shown) on the upper part is used to receive the driving signal (driving frequency and driving voltage). 4252 , the conductive frame 425 , and the conductive pins 4251 form a loop, and the insulating frame 424 blocks the conductive frame 425 from the actuator 423 to avoid short circuit, so that the driving signal can be transmitted to the piezoelectric plate 4233 . After receiving the driving signal (driving frequency and driving voltage), the piezoelectric plate 4233 is deformed due to the piezoelectric effect to further drive the piezoelectric carrier plate 4231 and adjust the resonance plate 4232 to generate reciprocating bending vibration.

Based on the above, the adjustment resonance plate 4232 is located between the piezoelectric plate 4233 and the piezoelectric carrier plate 4231, and as a buffer between the two, the vibration frequency of the piezoelectric carrier plate 4231 can be adjusted. Basically, the thickness of the adjustment resonance plate 4232 is greater than the thickness of the piezoelectric carrier plate 4231 , and the thickness of the adjustment resonance plate 4232 can be varied, thereby adjusting the vibration frequency of the actuating body 423 .

Please refer to Fig. 6A, Fig. 6B and Fig. 7A at the same time, the air injection hole sheet 421, the cavity frame 422, the actuating body 423, the insulating frame 424 and the conductive frame 425 are correspondingly stacked in sequence and arranged and positioned on the air guide assembly. In the bearing area 415, the piezoelectric actuator 42 is urged to be positioned in the bearing area 415 of the air guide assembly, and the bottom is fixed on the positioning bump 415b for support and positioning. Therefore, the piezoelectric actuator 42 is positioned between the suspension piece 4210 and the A gap 4212 is defined between the inner edges of the air guide assembly bearing area 415 for air circulation.

Referring again to FIG. 7A , an air flow chamber 427 is formed between the above-mentioned air injection hole sheet 421 and the bottom surface of the air guide element bearing area 415 . The airflow chamber 427 communicates with the resonance chamber 426 between the actuating body 423 , the cavity frame 422 and the suspension sheet 4210 through the hollow hole 4211 in the air injection hole sheet 421 , and controls the vibration frequency of the gas in the resonance chamber 426 to make it The vibration frequency of the suspension plate 4210 is close to the same, so that the resonance chamber 426 and the suspension plate 4210 can generate a Helmholtz resonance effect, so as to improve the gas transmission efficiency.

Fig. 7B and Fig. 7C are schematic diagrams of the operation of the piezoelectric actuator in Fig. 7A. Please refer to Fig. 7B first. When the piezoelectric plate 4233 moves to the bottom surface away from the air guide element bearing area 415, the piezoelectric plate 4233 drives the suspension sheet 4210 of the air jet hole sheet 421 to move away from the bottom surface of the air guide assembly bearing area 415, so that the volume of the air flow chamber 427 expands rapidly, and the internal pressure drops to form a negative pressure, which attracts the outside of the piezoelectric actuator 42. The gas flows in through the plurality of gaps 4212, and enters the resonance chamber 426 through the hollow holes 4211, so that the air pressure in the resonance chamber 426 increases to generate a pressure gradient; as shown in Fig. 7C, when the piezoelectric plate 4233 drives the air injection holes When the suspending sheet 4210 of the sheet 421 moves toward the bottom surface of the air guide assembly bearing area 415, the gas in the resonance chamber 426 flows out rapidly through the hollow hole 4211, squeezes the gas in the gas flow chamber 427, and makes the collected gas close to The ideal gas state of Bernoulli's law is rapidly and massively ejected and introduced into the vent hole 415 a of the air guide assembly bearing area 415 . Therefore, after repeating the actions of Fig. 7B and Fig. 7C, the piezoelectric plate 4233 vibrates reciprocally. According to the principle of inertia, the air pressure inside the resonant chamber 426 after exhausting is lower than the equilibrium air pressure, and the gas will be guided to enter again. In the resonance chamber 426, the vibration frequency of the gas in the resonance chamber 426 is controlled to be close to the same as the vibration frequency of the piezoelectric plate 4233, so as to generate the Helmholtz resonance effect, so as to realize the high-speed and large-scale transmission of the gas.

FIGS. 8A to 8C are schematic diagrams of the gas path of the gas detection module structure 4. Referring first to FIG. 8A, the gas enters from the air inlet frame port 461a of the outer cover 46 and passes through the air inlet port 414a. It enters the air inlet groove 414 of the base 41 and flows to the position of the particle sensor 45 . Again As shown in FIG. 8B , the continuous driving of the piezoelectric actuator 42 will absorb the gas in the air intake path, so that the external air can be quickly introduced and circulated stably, and pass above the particle sensor 45 . At this time, the laser element 44 emits a beam through the transparent The light window 414b enters the air inlet groove 414, and the air inlet groove 414 is irradiated with the suspended particles contained in it through the gas above the particle sensor 45. When the irradiated light beam touches the suspended particles, it scatters and produces a projected light spot. The particle sensor 45 The projected light spot generated by the scattering is received and calculated to obtain the relevant information of the particle size and concentration of the suspended particles contained in the gas, and the gas above the particle sensor 45 is also continuously driven and transmitted by the piezoelectric actuator 42 and introduced into the gas guide assembly The vent hole 415a of the bearing area 415 enters the first section 416b of the air outlet groove 416 . Finally, as shown in FIG. 8C, after the gas enters the first section 416b of the gas outlet groove 416, the gas in the first section 416b will be pushed because the piezoelectric actuator 42 will continuously deliver gas into the first section 416b.
