In addition, the actuator 223 further includes a piezoelectric carrier 2231, a tuning resonator plate 2232, and a piezoelectric plate 2233. The piezoelectric carrier 2231 is carried and stacked on the cavity frame 222. The tuning resonant plate 2232 is supported and stacked on the piezoelectric carrier 2231. The piezoelectric plate 2233 is carried overlying the tuning resonating plate 2232. The tuning resonator plate 2232 and the piezoelectric plate 2233 are accommodated in the insulating frame 224, and are electrically connected to the piezoelectric plate 2233 by the conductive electrode 2252 of the conductive frame 225.

Referring to fig. 9A, 9B and 10A, the air hole plate 221, the cavity frame 222, the actuating body 223, the insulating frame 224 and the conductive frame 225 are sequentially stacked and positioned in the air guide assembly bearing area 215, so that the piezoelectric actuator 22 is positioned in the air guide assembly bearing area 215 and supported and positioned on the positioning bump 215B by the bottom, and therefore, a gap 2212 is defined between the suspension plate 2210 and the inner edge of the air guide assembly bearing area 215 for air circulation by the piezoelectric actuator 22.
Referring to fig. 10A, an airflow chamber 227 is formed between the gas jet hole plate 221 and the bottom surface of the gas guide assembly carrying area 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 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 close to the same as the vibration frequency of the suspension 2210, so that the Helmholtz resonance effect (Helmholtz resonance) is generated between the resonance chamber 226 and the suspension 2210, and the gas transmission efficiency is improved.
In addition, fig. 10B and 10C are schematic views of the actuation 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 gas guide assembly carrying area 215, the piezoelectric plate 2233 drives the suspension plate 2210 of the gas injection hole plate 221 to move away from the bottom surface of the gas guide assembly carrying area 215, so that the volume of the gas flow chamber 227 is rapidly expanded, the internal pressure thereof is reduced to form a negative pressure, and the gas sucked from the outside of the piezoelectric actuator 22 flows into the resonance chamber 226 through the gap 2212, and enters the resonance chamber 226 through the hollow hole 2211, so that the gas pressure in the resonance chamber 226 is increased to generate a pressure gradient; as shown in fig. 10C, when the piezoelectric plate 2233 drives the suspension plate 2210 of the air jet hole plate 221 to move toward the bottom surface of the air guide assembly carrying area 215, the air in the resonance chamber 226 flows out rapidly through the hollow hole 2211, presses the air in the air flow chamber 227, and makes the converged air jet out rapidly and largely into the air vent 215a of the air guide assembly carrying area 215 in an ideal air state close to bernoulli's law. Accordingly, by repeating the actions of fig. 10B and fig. 10C, the piezoelectric plate 2233 is vibrated in a reciprocating manner, and the gas is guided to enter the resonant chamber 226 again by the fact that the internal air pressure of the resonant chamber 226 after the air is exhausted is lower than the balance air pressure according to the principle of inertia, so that the vibration frequency of the gas in the resonant chamber 226 is controlled to be approximately the same as the vibration frequency of the piezoelectric plate 2233, and a helmholtz resonance effect is generated, so that high-speed and mass transmission of the gas is realized.
Referring to fig. 11A to 11C, referring to fig. 11A, the gas is introduced through the inlet frame 261A of the cover 26, enters the inlet channel 214 of the base 21 through the inlet port 214a, and flows to the position of the particle sensor 25. As shown in fig. 8B, the piezoelectric actuator 22 continuously drives the gas that is sucked into the gas inlet path, so that the external gas is rapidly introduced and stably flows and passes through the upper portion of the particle sensor 25, at this time, the laser assembly 24 emits a light beam into the gas inlet channel 214 through the light-transmitting window 214B, the gas inlet channel 214 irradiates the suspended particles contained therein through the gas above the particle sensor 25, when the irradiated light beam contacts the suspended particles, the scattered light beam is scattered and generates a projected light spot, the particle sensor 25 receives the projected light spot generated by the scattering and calculates to obtain the information about the particle size and concentration of the suspended particles contained in the gas, and the gas above the particle sensor 25 is continuously transmitted by the piezoelectric actuator 22 and is introduced into the vent hole 215a of the gas guide assembly carrying area 215, and enters the first area 216B of the gas outlet channel 216. Finally, as shown in fig. 11C, after the gas enters the first section 216b of the gas outlet channel 216, the gas in the first section 216b is pushed to the second section 216C and finally is discharged through the gas outlet port 216a and the gas outlet frame port 261b, because the piezoelectric actuator 22 continuously transmits the gas into the first section 216b.
Referring to fig. 12 again, the base 21 further includes a light trapping region 217, the light trapping region 217 is hollowed from the first surface 211 to the second surface 212 and corresponds to the laser setting region 213, and the light trapping region 217 passes through the light transmission window 214b to enable the light beam emitted by the laser component 24 to be projected therein, the light trapping region 217 is provided with a light trapping structure 217a with an inclined cone, and the light trapping structure 217a corresponds to the path of the light beam emitted by the laser component 24; in addition, the optical trap structure 217a makes the projection beam emitted by the laser component 24 reflected in the optical trap area 217 in the inclined plane structure, so as to avoid the reflection of the beam to the position of the particle sensor 25, and a light trap distance D is maintained between the position of the projection beam received by the optical trap structure 217a and the light transmission window 214b, wherein the light trap distance D needs to be greater than 3mm, and when the light trap distance D is less than 3mm, the projection beam projected on the optical trap structure 217a is directly reflected back to the position of the particle sensor 25 due to excessive stray light, resulting in distortion of detection accuracy.
With continued reference to fig. 5C and 12, the gas detecting body 2b of the present invention can detect not only particles in a gas, but also characteristics of the introduced gas, such as formaldehyde, ammonia, carbon monoxide, carbon dioxide, oxygen, ozone, etc. Therefore, the gas detecting body 2b further includes a first volatile organic compound sensor 27a, which is positioned on the driving circuit board 23 and electrically connected thereto, and is accommodated in the gas outlet groove 216, and detects the gas guided out from the gas outlet path, so as to detect the concentration or the characteristic of the volatile organic compound contained in the gas outlet path. Alternatively, the gas detecting body 2b further includes a second volatile organic compound sensor 27b positioned on the driving circuit board 23 and electrically connected thereto, and the second volatile organic compound sensor 27b is accommodated in the light trapping region 217, so as to determine the concentration or characteristic of the volatile organic compound contained in the gas introduced into the light trapping region 217 through the light transmitting window 214b and the gas inlet path of the air inlet channel 214.
