In addition, the actuator 1323 further includes a piezoelectric carrier 1323a, an adjusting resonant plate 1323b and a piezoelectric plate 1323c, the piezoelectric carrier 1323a is stacked on the cavity frame 1322, the adjusting resonant plate 1323b is stacked on the piezoelectric carrier 1323a, the piezoelectric plate 1323c is stacked on the adjusting resonant plate 1323b, the adjusting resonant plate 1323b and the piezoelectric plate 1323c are accommodated in the insulating frame 1324, and are electrically connected to the piezoelectric plate 1323c by the conductive electrode 1325b of the conductive frame 1325, wherein the piezoelectric carrier 1323a and the adjusting resonant plate 1323b are made of electrically conductive materials, the piezoelectric carrier 1323a has a piezoelectric pin 1323d, the piezoelectric pin 1323d and the conductive pin 1325a are connected to a driving circuit (not shown) on the driving circuit board 133, to receive the driving signal (driving frequency and driving voltage), the driving signal is formed by the piezoelectric pin 1323d, the piezoelectric carrier 1323a, the tuning resonant plate 1323b, the piezoelectric plate 1323c, the conductive electrode 1325b, the conductive frame 1325, and the conductive pin 1325a, and the insulating frame 1324 blocks the conductive frame 1325 and the actuating body 1323 to avoid the occurrence of a short circuit, so that the driving signal is transmitted to the piezoelectric plate 1323c, and after the piezoelectric plate 1323c receives the driving signal (driving frequency and driving voltage), the piezoelectric carrier 1323a and the tuning resonant plate 1323b are further driven to generate the reciprocating bending vibration due to the deformation of the piezoelectric effect.

As described above, the tuning resonant plate 1323b is located between the piezoelectric plate 1323c and the piezoelectric carrier 1323a, and can be used as a buffer between the piezoelectric carrier 1323a and the piezoelectric carrier. Basically, the thickness of the tuning resonant plate 1323b is greater than the thickness of the piezoelectric carrier plate 1323a, and the thickness of the tuning resonant plate 1323b can be varied, thereby tuning the vibration frequency of the actuator 1323.

Referring to fig. 7A, the gas jet plate 1321, the cavity frame 1322, the actuating body 1323, the insulating frame 1324 and the conductive frame 1325 are sequentially stacked and disposed in the gas guide assembly bearing area 1315, and a gas flow chamber 1327 is formed between the gas jet plate 1321 and a bottom surface (not labeled) of the gas guide assembly bearing area 1315. The gas flow chamber 1327 communicates with the resonance chamber 1326 between the actuator 1323, the chamber frame 1322, and the suspension 1321a through the hollow hole 1321b of the gas ejection hole sheet 1321. By controlling the frequency of vibration of the gas in resonant cavity 1326 to be approximately the same as the frequency of vibration of floating sheet 1321a, helmholtz resonance effect (Helmholtz resonance) is created between resonant cavity 1326 and floating sheet 1321a, resulting in improved gas transfer efficiency.

Referring to fig. 7B and 7C, when the piezoelectric plate 1323C moves away from the bottom surface of the gas guide assembly carrying area 1315, the suspension sheet 1321a of the gas jet sheet 1321 is driven to move away from the bottom surface of the gas guide assembly carrying area 1315, so that the volume of the gas flow chamber 1327 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 132 flows into the plurality of voids 1321d and enters the resonance chamber 1326 through the hollow holes 1321B, so that the gas pressure in the resonance chamber 1326 is increased to generate a pressure gradient. As shown in fig. 7C, when the piezoelectric plate 1323C drives the suspension sheet 1321a of the air jet hole sheet 1321 to move toward the bottom surface of the air guide assembly carrying area 1315, the air in the resonance chamber 1326 flows out quickly through the hollow hole 1321b, presses the air in the air flow chamber 1327, and makes the converged air jet out quickly and largely in an ideal air state close to the bernoulli's law. Based on the principle of inertia, the exhausted resonant cavity 1326 has an internal gas pressure lower than the equilibrium gas pressure, which directs the gas into the resonant cavity 1326 again. Accordingly, by repeating the operations of fig. 7B and 7C, piezoelectric plate 1323C is caused to vibrate reciprocally, and the frequency of vibration of the gas in resonant cavity 1326 is controlled to be approximately the same as the frequency of vibration of piezoelectric plate 1323C, so as to generate the helmholtz resonance effect, thereby realizing high-speed and mass transfer of the gas.

Referring to fig. 8A to 8C, which are schematic diagrams of the gas path of the gas detection module 13, firstly, referring to fig. 8A, the gas enters through the gas inlet port 1361a of the cover 136, enters the gas inlet channel 1314 of the base 131 through the gas inlet port 1314a, flows to the position of the particle sensor 135, and then, as shown in fig. 8B, the piezoelectric actuator 132 continuously drives the gas that is sucked into the gas path, so that the external gas is rapidly introduced and stably flows through the top of the particle sensor 135, at this time, the projection beam emitted by the laser component 134 enters the gas inlet channel 1314 through the light-transmitting window 1314B, when the light beam contacts the suspended particles in the gas above the particle sensor 135, the projection beam scatters and generates a projection spot, the particle sensor 135 receives the projection spot generated by scattering, so as to obtain the relevant information of the particle size and concentration of the suspended particles in the gas, and the gas above the particle sensor 135 is continuously driven and transmitted by the piezoelectric actuator 132 to be introduced into the gas outlet channel 5a of the gas guide component bearing region 1315, so that the external gas is introduced into the gas outlet channel 1316B, and finally, the gas inlet channel 1316B is introduced into the gas outlet channel 1316C through the first window 131B, and the gas outlet channel 131B is not introduced into the gas outlet channel 131B, and finally, and the gas outlet channel 131C 6C is introduced into the gas outlet channel 131C 6B is introduced into the first region and the gas outlet channel 131C 6B, and the gas outlet channel 131C is finally, as shown in fig. 6C.

With continued reference to fig. 9 and 2C, the gas detection module 13 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 detection module 13 further includes a first volatile organic compound sensor 137a, which is positioned on the driving circuit board 133 and electrically connected thereto, and is accommodated in the gas outlet groove 1316, and is configured to detect the gas guided out of the gas outlet path, so as to detect the concentration or the characteristic of the volatile organic compound contained in the gas outlet path.
