As shown in fig. 9A and 9B, the piezoelectric actuator 22 includes a jet hole sheet 221, a cavity frame 222, an actuator 223, an insulating frame 224, and a conductive frame 225. The air hole sheet 221 is made of a flexible material, and has a suspension 2210 and a hollow hole 2211. The suspension plate 2210 is a bendable and vibrating plate-shaped structure, and the shape and size thereof substantially correspond to the inner edge of the air guide module carrying area 215, but not limited thereto, the suspension plate 2210 may be one of square, circular, oval, triangular and polygonal, and the hollow hole 2211 penetrates through the center of the suspension plate 2210 for air circulation.

The cavity frame 222 is stacked on the air injection hole piece 221, and the shape thereof corresponds to the air injection hole piece 221. The actuating body 223 is stacked on the cavity frame 222, and defines a resonant cavity 226 with the cavity frame 222 and the suspension plate 2210. The insulating frame 224 is stacked on the actuating body 223, and has an appearance similar to that of the chamber frame 222. The conductive frame 225 is stacked on the insulating frame 224, and has an appearance similar to the insulating frame 224, and the conductive frame 225 has a conductive pin 2251 and a conductive electrode 2252, the conductive pin 2251 extends outward from the outer edge of the conductive frame 225, and the conductive electrode 2252 extends inward from the inner edge of the conductive frame 225. In addition, the actuator 223 further includes a piezoelectric carrier 2231, a tuning resonator 2232, and a piezoelectric 2233. Piezoelectric carrier 2231 is carried and stacked on cavity frame 222. The tuning resonator plate 2232 is supported and stacked on the piezoelectric carrier plate 2231. The piezoelectric plate 2233 bears a stack of tuning resonator plates 2232. The tuning resonator plate 2232 and the piezoelectric plate 2233 are accommodated in the insulating frame 224, and the piezoelectric plate 2233 is electrically connected to the conductive electrode 2252 of the conductive frame 225.

The piezoelectric plate 2233 receives the driving signal (driving frequency and driving voltage), and then deforms due to the piezoelectric effect, thereby further driving the piezoelectric carrier plate 2231 and adjusting the resonator plate 2232 to generate reciprocating bending vibration.

As described above, the tuning resonator plate 2232 is located between the piezoelectric plate 2233 and the piezoelectric carrier plate 2231, and serves as a buffer between them, thereby tuning the vibration frequency of the piezoelectric carrier plate 2231. Basically, the thickness of the tuning resonance plate 2232 is greater than the thickness of the piezoelectric carrier plate 2231, and the thickness of the tuning resonance plate 2232 may be varied, thereby tuning the vibration frequency of the actuating body 223.

As shown in fig. 9A, 9B and 10A, the air hole sheet 221, the cavity frame 222, the actuator 223, the insulating frame 224 and the conductive frame 225 are correspondingly stacked and positioned in the air guide device supporting region 215 in sequence, so that the piezoelectric actuator 22 is supported and positioned in the air guide device supporting region 215 and is supported and positioned by the positioning bump 215B fixed at the bottom, and thus a gap 2212 is defined between the suspension 2210 and the inner edge of the air guide device supporting region 215 for the circulation of air by the piezoelectric actuator 22.

Referring to fig. 10A, an airflow chamber 227 is formed between the air injection hole sheet 221 and the bottom surface of the air guide member supporting region 215. The gas flow chamber 227 is communicated with the resonance chamber 226 among the actuating body 223, the cavity frame 222 and the suspension plate 2210 through the hollow hole 2211 of the gas injection hole plate 221, and the vibration frequency of the gas in the resonance chamber 226 is controlled to be approximately the same as that of the suspension plate 2210, so that the resonance chamber 226 and the suspension plate 2210 can generate a Helmholtz resonance effect (Helmholtz resonance) to improve the gas transmission efficiency.

Fig. 10B and 10C are schematic diagrams illustrating the operation of the piezoelectric actuator 22 in fig. 10A, please refer to fig. 10B, when the piezoelectric plate 2233 moves away from the bottom surface of the air guide assembly carrying region 215, the piezoelectric plate 2233 drives the suspension 2210 of the air hole piece 221 to move away from the bottom surface of the air guide assembly carrying region 215, so as to expand the volume of the air flow chamber 227 sharply, the internal pressure thereof decreases to form a negative pressure, and the air outside the piezoelectric actuator 22 is sucked into the resonant chamber 226 through the gap 2212 and the hollow hole 2211, so as to increase the air pressure in the resonant chamber 226 to generate a pressure gradient; as shown in fig. 10C, when the piezoelectric plate 2233 drives the suspension 2210 of the gas injection hole piece 221 to move toward the bottom surface of the gas guide module receiving area 215, the gas in the resonant cavity 226 flows out rapidly through the hollow hole 2211, and presses the gas in the gas flow cavity 227, so that the collected gas is rapidly and largely injected into the gas holes 215a of the gas guide module receiving area 215 in a state close to the ideal gas state of bernoulli's law. Therefore, by repeating the operations of fig. 10B and 10C, the piezoelectric plate 2233 is vibrated in a reciprocating manner, and according to the principle of inertia, the gas pressure inside the exhausted resonant cavity 226 is lower than the equilibrium gas pressure, which leads the gas to enter the resonant cavity 226 again, so that the vibration frequency of the gas in the resonant cavity 226 is controlled to be approximately the same as the vibration frequency of the piezoelectric plate 2233, thereby generating the helmholtz resonance effect, and realizing high-speed and large-volume transmission of the gas.

Referring to fig. 11A to 11C, which are schematic gas paths of the gas detecting body 2b, first, as shown in fig. 11A, the gases enter from the inlet frame port 261A of the cover 26, enter the inlet groove 214 of the base 21 through the inlet port 214a, and flow to the position of the particle sensor 25. As shown in fig. 8B, the piezoelectric actuator 22 continuously drives the gas sucking the air inlet path to facilitate rapid introduction and stable circulation of the external air, and the external air passes through the upper portion of the particle sensor 25, at this time, the laser assembly 24 emits a light beam into the air inlet groove 214 through the light-transmitting window 214B, the air inlet groove 214 is irradiated with the aerosol contained in the air inlet path by the gas above the particle sensor 25, the light beam is scattered and generates a projected light spot when contacting the aerosol, the particle sensor 25 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 air, and the gas above the particle sensor 25 is continuously driven by the piezoelectric actuator 22 to be introduced into the air vent 215a of the air guide assembly carrying area 215 and enter the first area 216B of the air outlet groove 216. Finally, as shown in fig. 11C, after the gas enters the first section 216b of the gas outlet groove 216, since the piezoelectric actuator 22 continuously delivers the gas into the first section 216b, the gas in the first section 216b will be pushed to the second section 216C, and finally be exhausted through the gas outlet 216a and the gas outlet 261 b.

Referring to fig. 12, the base 21 further includes a light trap region 217, the light trap region 217 is formed by hollowing from the first surface 211 to the second surface 212 and corresponds to the laser installation region 213, and the light trap region 217 passes through the light-transmitting window 214b so that the light beam emitted by the laser element 24 can be projected into the light trap region 217, the light trap region 217 is provided with a light trap structure 217a having an oblique cone surface, and the light trap structure 217a corresponds to the path of the light beam emitted by the laser element 24; in addition, the light trap structure 217a reflects the projection light beam emitted by the laser assembly 24 into the light trap region 217 in the oblique cone structure, so as to prevent the light beam from reflecting to the position of the particle sensor 25, and a light trap distance D is maintained between the position of the projection light beam received by the light trap structure 217a and the light-transmitting window 214b, where the light trap distance D needs to be greater than 3mm, and when the light trap distance D is smaller than 3mm, the projection light beam projected on the light trap structure 217a is reflected back to the position of the particle sensor 25 directly due to excessive stray light, so that distortion of detection accuracy is caused.

As shown in fig. 5C and fig. 12, the gas detecting body 2b can detect not only particles in the gas, but also characteristics of the introduced gas, such as formaldehyde, ammonia, carbon monoxide, carbon dioxide, oxygen, ozone, and the like.
