As shown in fig. 4, the laser assembly 34 and the particle sensor 35 are both disposed on the driving circuit board 33 and located in the base 31, and the driving circuit board 33 is omitted in fig. 4 for the purpose of clearly explaining the positions of the laser assembly 34, the particle sensor 35 and the base 31; referring to fig. 4, the laser assembly 34 is accommodated in the laser installation region 313 of the base 31, the particle sensor 35 is accommodated in the air inlet groove 314 of the base 31 and aligned with the laser assembly 34, the laser assembly 34 corresponds to the light-transmitting window 314b for laser light emitted by the laser assembly 34 to pass through, so that the laser light irradiates the air inlet groove 314, and a beam path emitted by the laser assembly 34 passes through the light-transmitting window 314b and forms an orthogonal direction with the air inlet groove 314.

In addition, by the operation of the piezoelectric actuator 32, the gas outside the device body 1 can be further guided to enter the gas channel 13 from the gas inlet 11, then pass through the gas detection module 3 of the gas channel 13, and finally be discharged from the gas outlet 12, and the guided gas is detected by the particle sensor 35 to obtain a gas information.

As shown in fig. 6A and 6B, the piezoelectric actuator 32 includes a jet hole piece 321, a cavity frame 322, an actuator 323, an insulating frame 324, and a conductive frame 325.

The air hole piece 321 is made of a flexible material and has a suspension piece 321a, a hollow hole 321b and a plurality of connecting pieces 321 c. The suspension plate 321a is a plate-shaped structure capable of bending and vibrating, and the shape and size thereof approximately correspond to the inner edge of the air guide assembly carrying region 315, but not limited thereto, and the shape of the suspension plate 321a may be one of square, circle, ellipse, triangle, and polygon. The hollow hole 321b is formed through the center of the floating plate 321a for gas to flow through. In this embodiment, the number of the connecting members 321c is four, the number and the type of the connecting members 321c mainly correspond to the positioning notches 315b of the air guide device bearing region 315, and each connecting member 321c and the corresponding positioning notch 315b form a fastening structure for fastening and fixing with each other, so that the piezoelectric actuator 32 can be disposed in the air guide device bearing region 315.

The cavity frame 322 is stacked on the air injection hole piece 321, and the shape thereof corresponds to the air injection hole piece 321. The actuating body 323 is stacked on the cavity frame 322, and defines a resonant cavity 326 between the cavity frame 322 and the floating plate 321 a. An insulating frame 324 is stacked on the actuating body 323, and has an appearance similar to that of the cavity frame 322. The conductive frame 325 is stacked on the insulating frame 324, and has an appearance similar to that of the insulating frame 324, and the conductive frame 325 has a conductive pin 325a and a conductive electrode 325 b. The conductive pin 325a extends outward from the outer edge of the conductive frame 325, and the conductive electrode 325b extends inward from the inner edge of the conductive frame 325. In addition, the actuator 323 further includes a piezoelectric carrier 323a, an adjusting resonator plate 323b and a piezoelectric plate 323c, wherein the piezoelectric carrier 323a is stacked on the cavity frame 322, the adjusting resonator plate 323b is stacked on the piezoelectric carrier 323a, the piezoelectric plate 323c is stacked on the adjusting resonator plate 323b, and the adjusting resonator plate 323b and the piezoelectric plate 323c are accommodated in the insulating frame 324 and electrically connected to the piezoelectric plate 323c through the conductive electrode 325b of the conductive frame 325. The piezoelectric carrier 323a and the tuning resonator plate 323b are made of conductive material, the piezoelectric carrier 323a has a piezoelectric pin 323d, and the piezoelectric pin 323d and the conductive pin 325a are connected to a driving circuit (not shown) on the driving circuit board 33 for receiving driving signals (driving frequency and driving voltage). The driving signal is formed into a loop by the piezoelectric pin 323d, the piezoelectric carrier plate 323a, the tuning resonator plate 323b, the piezoelectric plate 323c, the conductive electrode 325b, the conductive frame 325, and the conductive pin 325a, and the insulating frame 324 separates the conductive frame 325 from the actuator 323 to avoid short circuit, so that the driving signal is transmitted to the piezoelectric plate 323c, and after receiving the driving signal (driving frequency and driving voltage), the piezoelectric plate 323c deforms due to the piezoelectric effect to further drive the piezoelectric carrier plate 323a and tune the resonator plate 323b to generate reciprocating bending vibration.

As described above, the tuning resonator plate 323b is located between the piezoelectric plate 323c and the piezoelectric carrier plate 323a, and serves as a buffer between the two, thereby tuning the vibration frequency of the piezoelectric carrier plate 323 a. Basically, the thickness of the tuning resonance plate 323b is larger than that of the piezoelectric carrier plate 323a, and the thickness of the tuning resonance plate 323b is varied, thereby tuning the vibration frequency of the actuating body 323.

As shown in fig. 6A, fig. 6B and fig. 7A, a plurality of connecting members 321c define a plurality of gaps 321d between the floating plate 321a and the inner edge of the air guide device supporting region 315 for air to flow through.

Referring to fig. 7A, the air injection hole 321, the cavity frame 322, the actuator 323, the insulating frame 324, and the conductive frame 325 are correspondingly stacked and disposed in the air guide assembly supporting region 315. An air flow chamber 327 is formed between the air hole piece 321 and a bottom surface (not labeled) of the air guide assembly carrying region 315. The air flow chamber 327 communicates with the resonance chamber 326 among the actuating body 323, the chamber frame 322 and the floating piece 321a through the hollow hole 321b of the air injection hole piece 321. By controlling the vibration frequency of the gas in the resonance chamber 326 to be approximately the same as the vibration frequency of the floating plate 321a, a Helmholtz resonance effect (Helmholtz resonance) can be generated between the resonance chamber 326 and the floating plate 321a, so as to improve the gas transmission efficiency.

Referring to fig. 7B, fig. 7B and fig. 7C are schematic operation diagrams of the piezoelectric actuator of fig. 7A, and referring to fig. 7B, when the piezoelectric plate 323C moves away from the bottom surface of the air guide assembly holding area 315, the floating piece 321a of the air injection hole piece 321 is driven to move away from the bottom surface of the air guide assembly holding area 315, so as to expand the volume of the air flow chamber 327 abruptly, the internal pressure thereof decreases to form a negative pressure, and the air outside the piezoelectric actuator 32 is sucked to flow into the resonance chamber 326 through the plurality of gaps 321d and the hollow holes 321B, so that the air pressure in the resonance chamber 326 increases to generate a pressure gradient. As shown in fig. 7C, when the piezoelectric plate 323C drives the suspending pieces 321a of the air injection hole pieces 321 to move toward the bottom surface of the air guide assembly supporting region 315, the gas in the resonant chamber 326 flows out rapidly through the hollow holes 321b, and the gas in the gas flow chamber 327 is squeezed, so that the collected gas is rapidly and largely injected in a state close to the ideal gas state of the bernoulli's law. Based on the principle of inertia, the exhausted gas pressure inside the resonant chamber 326 is lower than the equilibrium gas pressure, which leads the gas to enter the resonant chamber 326 again. Thus, by repeating the operations of fig. 7B and 7C, the piezoelectric plate 323C is vibrated in a reciprocating manner, and the vibration frequency of the gas in the resonant chamber 326 and the vibration frequency of the piezoelectric plate 323C are controlled to be approximately the same, so as to generate the helmholtz resonance effect, thereby realizing high-speed and large-volume gas transmission.

Referring to fig. 8A to 8C, which are schematic diagrams illustrating gas paths of the gas detection module 3, first, as shown in fig. 8A, the gases enter from the inlet frame opening 361a of the cover 36, enter the inlet groove 314 of the base 31 through the inlet port 314a, and flow to the position of the particle sensor 35. As shown in fig. 8B, the piezoelectric actuator 32 continuously drives the gas sucking path, so as to facilitate the rapid introduction and stable circulation of the external gas, and passes over the particle sensor 35, while the laser assembly 34 emits a projected beam of light through the light-transmissive window 314b into the air intake channel 314, irradiating the air intake channel 314 through aerosols contained in the gas above the particle sensor 35, while the beam of light contacts the aerosols, scatters and generates a projected light spot, the particle sensor 35 receives the projected light spot generated by scattering and calculates to obtain information on the particle size and concentration of the aerosol contained in the gas, the gas above the particle sensor 35 is also continuously driven by the piezoelectric actuator 32 to be introduced into the vent hole 315a of the gas guide assembly carrying region 315, and enters the first section 316b of the gas outlet trench 316 (refer back to fig. 3A). Finally, as shown in fig. 8C, after the gas enters the first section 316b of the gas outlet trench 316, since the piezoelectric actuator 32 continuously transports the gas into the first section 316b, the gas in the first section 316b will be pushed to the second section 316C, and finally discharged through the gas outlet 316a and the frame outlet 361 b.

Referring again to FIG. 9, the susceptor 31 further includes a light trapping region 317. The optical trap region 317 is formed by hollowing from the first surface 311 to the second surface 312 and corresponds to the laser disposing region 313, and the optical trap region 317 passes through the light-transmitting window 314b so that the light beam emitted by the laser element 34 can be projected therein. The optical trap region 317 has a tapered optical trap structure 317a, and the optical trap structure 317a corresponds to the path of the light beam emitted from the laser module 34. In addition, the light trap structure 317a reflects the projection light beam emitted by the laser component 34 into the light trap region 317 in an oblique cone structure, so as to avoid the light beam from reflecting to the position of the particle sensor 35, and a light trap distance D is maintained between the position of the projection light beam received by the light trap structure 317a and the light-transmitting window 314b, where the light trap distance D needs to be greater than 3mm, and when the light trap distance D is less than 3mm, the projection light beam projected on the light trap structure 317a is reflected back to the position of the particle sensor 35 due to excessive stray light, so that distortion of detection accuracy is caused.

As shown in fig. 9 and fig. 2C, the gas detecting module 3 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. Therefore, the gas detection module 3 further includes a first volatile organic compound sensor 37a, which is positioned on the driving circuit board 33 and electrically connected thereto, and is accommodated in the gas outlet groove 316 to detect the gas guided out from the gas outlet path, so as to detect the concentration or characteristics of the volatile organic compounds contained in the gas outlet path. Or the gas detection module 3 further includes a second volatile organic compound sensor 37b, which is positioned on the driving circuit board 33 and electrically connected thereto, and the second volatile organic compound sensor 37b is accommodated in the optical trap region 317, for the concentration or characteristics of volatile organic compounds contained in the gas passing through the gas inlet path of the gas inlet trench 314 and passing through the light-transmitting window 314b and introduced into the optical trap region 317.

Referring to fig. 1 and 10, the household device 100 further includes a control circuit unit 4, the control circuit unit 4 is provided with a microprocessor 4a and a communicator 4b, and the gas detection module 3 is electrically connected thereto. The microprocessor 4a can control the driving signal of the gas detection module 3 to detect the start operation, and convert the detection data of the gas detection module 3 into a detection data for storage, and the microprocessor 4a can control the driving signal and the start operation of the piezoelectric actuator 32, and control the start operation of the whole device according to the detection data, so as to automatically start the piezoelectric actuator 32 and automatically control and adjust the air volume. The communicator 4b can receive the detection data output by the microprocessor 4a and transmit the detection data to an external device 5 for storage through communication, so as to prompt the external device 5 to generate a gas detection message and a notification alarm. The external device 5 can be a cloud system, a portable mobile device, a computer system, etc.; the communication transmission may be a communication transmission by wire, for example: USB connection communication transmission, or communication transmission by wireless, for example: Wi-Fi communication transmission, Bluetooth communication transmission, RFID communication transmission, a near field communication transmission, and the like.
