[0002] With the rapid development of the world's population and industries, air quality is gradually deteriorating. Since people are exposed to these harmful air pollutions for a long time, it is harmful not only to human health but also to life.
[0003] In the air, for example, there are many pollutants such as carbon dioxide, carbon monoxide, formaldehyde, bacteria, fungi, volatile organic compounds (VOCs), fine particulate matter 2.5 (PM 2.5 ), or ozone. When the concentration of pollutants increases, it may cause serious harm to the human body. For example, regarding PM 2.5 , such fine particles penetrate into the alveoli, follow the body's blood circulation, and not only harm the respiratory system but also increase the risk of cardiovascular diseases or cancer.
[0004] Today, with the spread of epidemic diseases such as influenza and pneumonia, people's health is threatened, so people's social activities are restricted, and they relatively rarely go out on public transportation, and people are getting used to going out by car.

[0008] Some typical embodiments showing the features and advantages of the present invention will be described in the following explanation. It should be understood that the present invention can have various changes in different aspects, all without departing from the scope of the present invention, and the description and drawings are essentially used for illustration and are not intended to limit the present invention.
[0009] As shown in FIGS. 1A to 12, the present invention provides an in-vehicle air pollution control system that is applied to filter and exchange gas pollution inside the vehicle and quickly filter the gas pollution inside the vehicle to form a state where clean and complete breathing is possible. The in-vehicle air pollution control system includes a plurality of gas detection modules, a vehicle body gas air-conditioning control device 2, and a plurality of filtration and purification assemblies D.
[0010] The plurality of gas detection modules include a plurality of in-vehicle gas detection modules 1a and a plurality of out-of-vehicle gas detection modules 1b. The in-vehicle gas detection module 1a is installed at the position of the external air supply port 213 of the in-vehicle A, detects the air pollution source inside the in-vehicle A, and is used to transmit gas detection data. In an embodiment, the in-vehicle gas detection module 1a is a mobile detection device, that is, the in-vehicle gas detection module 1a is a wearable device such as a wristwatch or a wristband. In that case, it can be directly worn on the human body (not shown) to detect the gas pollution in the in-vehicle space at any time when a person gets into the in-vehicle A. The out-of-vehicle gas detection module 1b is installed outside the vehicle B, detects the external gas of the out-of-vehicle B, and is used to transmit gas detection data.
[0011] The vehicle body air-conditioning control device 2 controls the introduction or non-introduction of the outside air of the outside B into the vehicle interior A. The vehicle body air-conditioning control device 2 includes a ventilation path 21, a control drive unit 22, and an air supply control member 24. The control drive unit 22 has a touch display 221 used for touch setting of the control commands of the vehicle body air-conditioning control device 2 and display of the gas detection data inside the vehicle. As shown in FIGS. 2A to 2D, the ventilation path 21 is provided with a blower C, at least one exhaust port 211, at least one air supply port 212, and an outside air supply port 213. The blower C guides the air supply of at least one exhaust port 211, the air supply of the outside air supply port 213, and the air supply of at least one air supply port 212. As shown in FIGS. 2C and 2D, at least one exhaust port 211 communicates with the ventilation path 21 in FIG. 2A so that the gas is discharged to the outside B through the ventilation path 21 after being discharged from the exhaust port 211.
[0012] The filtration and purification assembly D is arranged at each of the exhaust port 211 and the air supply port 212 in the ventilation path 21 to filter and purify the outside air and the air pollution source. At least one in-vehicle gas detection module 1a is arranged on both sides of the filtration and purification assembly D. The gas detection data before and after filtration are detected by the in-vehicle gas detection modules 1a on both sides. The control drive unit 22 receives and compares the gas detection data output from the outside air gas detection module 1b and the gas detection data output from the in-vehicle gas detection module 1a, and drives the filtration and purification assembly D to filter the outside air and the air pollution source to form clean air and introduce it into the vehicle interior A.
[0013] The control drive unit 22 of the vehicle body gas air conditioning control device 2 controls the opening and closing of the air supply control member 24, receives and compares the gas detection data output from the outside air detection module 1b and the gas detection data output from the inside air detection module 1a, determines and selects the opening and closing of the external air supply port 213, thereby controlling the introduction or non-introduction of the external gas outside the vehicle into the vehicle interior A, and also controls in real time the operation of the air blower C of the vehicle body gas air conditioning control device 2 in the monitoring mechanism state. As shown in FIGS. 2A and 2D, the external air supply port 213 and the air supply port 212 are used to introduce the external gas outside the vehicle and the air pollution source inside the vehicle into the vehicle body gas air conditioning control device 2 by the opening and closing control of the air supply control member 24, and after filtering and purifying the external gas and the air pollution source by the filtration and purification assembly D, they are discharged to the outside of the vehicle B through the ventilation path 21.
[0014] In a preferred embodiment, the control drive unit 22 of the vehicle body gas air conditioning control device 2 can determine the position of the air pollution source inside the vehicle by receiving and comparing the gas detection data detected by at least three inside air detection modules 1a and performing intelligent calculations. Also, the filtration and purification assembly D installed at the position of the air supply port 212 near the air pollution source can be intelligently selected and driven to accelerate the filtration of the air pollution source.
[0015] In another preferred embodiment, the control drive unit 22 of the vehicle body gas air conditioning control device 2 can determine the position of the air pollution source inside the vehicle by receiving and comparing the gas detection data detected by at least three inside air detection modules 1a and performing intelligent calculations. Also, by intelligently selecting and driving the exhaust port 211 near the air pollution source to exhaust preferentially, the air pollution source is sucked into the air supply port 212 nearby. At the same time, the control drive unit 22 of the vehicle body gas air conditioning control device 2 is driven to intelligently select and exhaust other exhaust ports 211 by intelligent calculation. Thereby, the air pollution source can be guided to the air supply port 212 near the air pollution source, and an air flow for quickly sucking and filtering can be formed.
[0016] In this embodiment, the monitoring mechanism state of the air pollution source means that the detection data detected by the gas detection module in the vehicle interior A exceeds the safety detection value. The safety detection value is that the amount of particulate matter 2.5 is less than 35 μg / m 3 , the concentration value of carbon dioxide is less than 1000 ppm, the concentration value of total volatile organic compounds is less than 0.56 ppm, the concentration value of formaldehyde is less than 0.08 ppm, the amount of bacteria is less than 1500 CFU / m 3 , the amount of fungi is less than 1000 CFU / m 3 , the concentration value of sulfur dioxide is less than 0.075 ppm, the concentration value of nitrogen dioxide is less than 0.1 ppm, the concentration value of carbon monoxide is less than 9 ppm, the concentration value of ozone is less than 0.06 ppm, or the concentration value of lead is less than 0.15 μg / m 3 .
[0017] As shown in FIGS. 2A and 2B, in other embodiments of the present invention, the vehicle interior air pollution control system of the present invention further includes at least one purification filter 3. The purification filter 3 includes a blower C and a filtration and purification assembly D, and the vehicle interior gas detection module 1a can be assembled to the purification filter 3. The vehicle interior gas detection module 1a transmits gas detection data so that the control drive unit 22 of the vehicle body gas air conditioning control device 2 receives and compares the gas detection data and performs intelligent calculations, and operates the purification filter 3 near the air pollution source and operates the blower C to guide the air pollution source in the vehicle interior A to the filtration and purification assembly D of the purification filter 3 for filtration and purification. In other embodiments, each purification filter 3 can be installed so as to be embedded in the interior trim panel, seat, or door pillar of the vehicle.
[0018] In a preferred embodiment, the control drive unit 22 of the vehicle body gas air conditioning control device 2 determines the position of the air pollution source in the vehicle interior A, operates the purification filter 3 near the air pollution source, and receives and compares the vehicle interior gas detection data detected by at least three vehicle interior gas detection modules 1a to perform intelligent calculations in order not to suck in and diffuse the air pollution source and to accelerate filtration.
[0019] In another preferred embodiment, the control driving unit 22 of the vehicle body gas air-conditioning control device 2 receives and compares the in-vehicle gas detection data detected by at least three in-vehicle gas detection modules 1a and performs intelligent calculations. Thereby, the position of the air pollution source in the vehicle interior A is determined, and the purification filter 3 near the air pollution source is intelligently selected and controlled to operate preferentially. In addition, the control driving unit 22 of the vehicle body gas air-conditioning control device 2 applies artificial intelligence calculations, selects and operates a plurality of other purification filters 3, guides the air pollution source to the purification filter 3 near the air pollution source, and can form an air flow for rapid filtration.
[0020] On both sides of the plurality of purification filters 3, at least one in-vehicle gas detection module 1a is installed respectively. The in-vehicle gas detection modules 1a on both sides detect the gas detection data before and after filtration, and the control driving unit 22 receives and compares the gas detection data output from the in-vehicle gas detection module 1a at the position of the plurality of purification filters 3, so as to ensure that the plurality of purification filters 3 introduce the clean air formed by filtering the air pollution source into the vehicle interior A.
[0021] In this embodiment, the monitoring mechanism state of the air pollution source means that the detection data detected by the gas detection module in the vehicle interior A exceeds the safety detection value. The safety detection value is that the amount of suspended particles 2.5 is less than 35 μg / m 3 , the concentration value of carbon dioxide is less than 1000 ppm, the concentration value of total volatile organic compounds is less than 0.56 ppm, the concentration value of formaldehyde is less than 0.08 ppm, the amount of bacteria is less than 1500 CFU / m 3 , the amount of fungi is less than 1000 CFU / m 3 , the concentration value of sulfur dioxide is less than 0.075 ppm, the concentration value of nitrogen dioxide is less than 0.1 ppm, the concentration value of carbon monoxide is less than 9 ppm, the concentration value of ozone is less than 0.06 ppm, or the concentration value of lead is less than 0.15 μg / m 3 including being less than.
[0022] The above-mentioned filtration and purification assembly D may combine various forms. For example, it may be a combination of activated carbon D1 and a High-Efficiency Particulate Air (HEPA) filter D2, or a combination of activated carbon D1, a High-Efficiency Particulate Air (HEPA) filter D2, and a zeolite mesh D3. The activated carbon D1 is used to adsorb and filter particulate matter 2.5 (PM 2.5 ), the zeolite mesh D3 is used to adsorb and filter volatile organic compounds (VOCs), the high-efficiency filter D2 is used to adsorb and filter photochemical smog, bacteria, dust particles, and pollen contained in the gas, and realizes the filtration and purification effect on gas pollution in the filtration and purification assembly D. In other embodiments, a chlorine dioxide purifying agent can be applied to the high-efficiency filter D2 to suppress viruses, bacteria, and fungi in the gas of the filtration and purification assembly D. By applying a chlorine dioxide purifying agent to the high-efficiency filter D2, the suppression rate against viruses, bacteria, fungi, influenza A virus, influenza B virus, enterovirus, and norovirus contained in the gas pollution of the filtration and purification assembly D reaches 99% or more, and cross-infection of viruses can be reduced. In other embodiments, an organic protective coating extracted from ginkgo leaves and camellia japonica may be applied to the high-efficiency filter D2, thereby forming an organic protective anti-allergy filter, effectively resisting allergies, and also destroying the surface proteins of influenza viruses introduced into the filtration and purification assembly D and passing through the high-efficiency filter D2 and the surface proteins of influenza viruses (e.g., H1N1) in the gas passing through the high-efficiency filter D2. In other embodiments, silver ions are applied to the high-efficiency filter D2 to suppress viruses, bacteria, and fungi in the gas introduced into the filtration and purification assembly D.
[0023] In other embodiments, the filtration and purification assembly D may be composed of activated carbon D1, a high-efficiency filter D2, a zeolite mesh D3, and a photocatalyst unit D4. When outdoor air pollution is introduced into the filtration and purification assembly D, the photocatalyst unit D4 that can convert light energy into electrical energy decomposes harmful substances in the air and performs disinfection and sterilization, thereby realizing the filtration and purification effect of the air.
[0024] In other embodiments, the filtration and purification assembly D may be composed of activated carbon D1, a high-efficiency filter D2, a zeolite mesh D3, and a photo-plasma unit D5. Since the photo-plasma unit D5 is equipped with optical nanotubes, the optical nanotubes irradiate the air pollution introduced into the filtration and purification assembly D, promoting the decomposition and purification of volatile organic gases contained in the air pollution. When the filtration and purification assembly D introduces air pollution, the optical nanotubes irradiate the introduced air, decomposing oxygen molecules and water molecules in the air into highly oxidative photo-plasma, and forming an ion airflow that can destroy (decompose) organic molecules. Gas molecules such as volatile formaldehyde, toluene, and volatile organic compounds (VOC) contained in the air can be decomposed into water and carbon dioxide, thereby realizing the filtration and purification effect of the air.
[0025] In other embodiments, the filtration and purification assembly D may be composed of activated carbon D1, a high-efficiency filter D2, a zeolite mesh D3, and a negative ion unit D6. The filtration and purification assembly D performs high-voltage discharge on the air pollution introduced from the outside, so that the positively charged particles contained in the air pollution adhere to the dust collection plate with a negative charge, realizing the filtration and purification effect on the introduced air pollution.
[0026] In other embodiments, the filtration and purification assembly D may be composed of activated carbon D1, a high-efficiency filter D2, a zeolite mesh D3, and a plasma ion unit D7. The plasma ion unit D7 forms a high-voltage plasma column, and the plasma ions in the high-voltage plasma column decompose the viruses and bacteria in the gaseous contamination introduced from the outside by the filtration and purification assembly D, and the plasma ions electrolytically separate the oxygen molecules and water molecules contained in the gas to form cations (H + +) and anions (O2 - -). Substances that adhere to the water molecules around the ions adhere to the surfaces of the viruses and bacteria, and then, through a chemical reaction, are converted into highly oxidative reactive oxygen species (hydroxyl, OH groups), which extract the hydrogen atoms of the surface proteins of the viruses and bacteria and are oxidized and decomposed. Thereby, the introduced gas can be filtered to achieve the effect of filtration and purification.
[0027] In other embodiments, the filtration and purification assembly D may be only the high-efficiency filter D2, or a form in which the high-efficiency filter D2 is arbitrarily combined with one selected from the group consisting of a photocatalyst unit D4, a photo-plasma unit D5, a negative ion unit D6, and a plasma ion unit D7, or a form in which the high-efficiency filter D2 is arbitrarily combined with two selected from the group consisting of a photocatalyst unit D4, a photo-plasma unit D5, a negative ion unit D6, and a plasma ion unit D7, or a form in which the high-efficiency filter D2 is arbitrarily combined with three selected from the group consisting of a photocatalyst unit D4, a photo-plasma unit D5, a negative ion unit D6, and a plasma ion unit D7, or a form in which the high-efficiency filter D2 is combined with all of the photocatalyst unit D4, the photo-plasma unit D5, the negative ion unit D6, and the plasma ion unit D7.
[0028] Note that the service life of the high-efficiency filter D2 is determined with reference to the calculation results of the monitoring mechanism of the gas detection data detected by the in-vehicle gas detection module 1a and the out-vehicle gas detection module 1b, and the cumulative start time of the blower C in the vehicle body gas air-conditioning control device 2.
[0029] After understanding the method for filtering in-vehicle gas pollution of the present invention, the implementation device of the present invention will be described in detail below.
[0030] As shown in FIG. 3, the in-vehicle gas detection module 1a and the out-of-vehicle gas detection module 1b include a control circuit board 11, a gas detection body 12, a microprocessor 13, and a communicator 14. The gas detection body 12, the microprocessor 13, and the communicator 14 are packaged on the control circuit board 11 to form an integrated type and are electrically connected to each other. The microprocessor 13 and the communicator 14 are arranged on the control circuit board 11. The microprocessor 13 controls the drive signal of the gas detection body 12 to perform a detection operation, receives the gas pollution detected by the gas detection body 12, performs calculation and processing of data, and also transmits it externally via the communicator 14, or can convert the detection information (gas) of the gas detection body 12 into detection data and save it. The communicator 14 receives the detection data (gas) output from the microprocessor 13 and transfers the detection data to a cloud processing device (not shown) or an external device (not shown). The external device is a portable mobile device (not shown). The above transmission of the communicator 14 to the outside is, for example, a wired bidirectional communication transmission method such as USB, mini-USB, micro-USB, etc., or a wireless bidirectional communication transmission method such as a Wi-Fi module, a Bluetooth module, a radio frequency identification module, a near-field communication module, etc.
[0031] The above gas pollution is any one or a combination of suspended particles, carbon monoxide, carbon dioxide, ozone, sulfur dioxide, nitrogen dioxide, lead, total volatile organic compounds, formaldehyde, bacteria, fungi, and viruses.
[0032] A more detailed description will be given with reference to FIGS. 4A to 9A. The gas detection body 12 includes a base 121, a piezoelectric actuator 122, a drive circuit board 123, a laser assembly 124, a particulate sensor 125, a cover member 126, and a gas sensor 127. The base 121 has a first surface 1211, a second surface 1212, a laser installation area 1213, an air supply groove portion 1214, a gas guide assembly support area 1215, and an exhaust groove portion 1216. The first surface 1211 and the second surface 1212 are disposed on two surfaces facing each other. The laser assembly 124 is formed by being hollowed out from the first surface 1211 toward the second surface 1212. The cover member 126 covers the base 121 and has a side panel 1261. The side panel 1261 includes an air supply port 1261a and an exhaust port 1261b. The air supply groove portion 1214 is formed by recessing the second surface 1212 and is adjacent to the laser installation area 1213. The air supply groove portion 1214 is provided with an air supply opening 1214a that communicates with the outside of the base 121 and corresponds to the exhaust opening 1216a of the cover member 126. Light transmission windows 1214b that penetrate the side walls are provided on both side walls of the air supply groove portion 1214, so that the air supply groove portion 1214 communicates with the laser installation area 1213. With this structure, when the first surface 1211 of the base 121 is covered by the cover member 126 and the second surface 1212 is covered by the drive circuit board 123, an air supply path is defined in the air supply groove portion 1214.
[0033] The air guiding assembly support region 1215 is formed by recessing the second surface 1212, communicates with the air supply groove portion 1214, and has air vents 1215a penetrating through the bottom surface. Positioning blocks 1215b are provided at the four corners of the air guiding assembly support region 1215 respectively. An exhaust opening 1216a is provided in the exhaust groove portion 1216, and the exhaust opening 1216a is installed corresponding to the exhaust port 1261b of the cover member 126. The exhaust groove portion 1216 includes a first region 1216b formed by recessing the first surface 1211 in the vertical projection region onto the air guiding assembly support region 1215, and a second region 4216c formed by punching out the first surface 1211 in the extending region that does not overlap with the vertical projection region onto the air guiding assembly support region 1215 toward the second surface 1212. The first region 1216b and the second region 1216c communicate with each other and form a step. The first region 1216b of the exhaust groove portion 1216 communicates with the air vents 1215a of the air guiding assembly support region 1215. The second region 1216c of the exhaust groove portion 1216 communicates with the exhaust opening 1216a. Therefore, when the first surface 1211 of the base 121 is covered by the cover member 126 and the second surface 1212 is covered by the drive circuit board 123, the exhaust groove portion 1216 defines an exhaust path together with the drive circuit board 123.
[0034] The above laser assembly 124 and the particulate sensor 125 are both disposed on the drive circuit board 123 and located within the base 121. To clearly show the positions of the laser assembly 124, the particulate sensor 125, and the base 121, the drive circuit board 123 is intentionally omitted. The laser assembly 124 is housed in the laser installation area 1213 of the base 121, the particulate sensor 125 is housed in the air supply groove portion 1214 of the base 121, and is arranged to be aligned with the laser assembly 124. The laser assembly 124 corresponds to the light transmission window 1214b, and the light transmission window 1214b is provided so that the laser light emitted from the laser assembly 124 can pass through, and the transmitted laser light irradiates the air supply groove portion 1214. The path of the light beam emitted from the laser assembly 124 passes through the light transmission window 1214b and is arranged in a direction orthogonal to the air supply groove portion 1214. The light beam emitted from the laser assembly 124 passes through the light transmission window 1214b and enters the air supply groove portion 1214, irradiating the gas in the air supply groove portion 1214. When the light beam hits the floating particles in the gas, it scatters to form a particulate projection. The particulate sensor 125 is arranged in the orthogonal direction thereto, and receives and calculates the particulate projection due to scattering in order to obtain the detection data of the gas. The gas sensor 127 is disposed on the drive circuit board 123 and electrically connected thereto, and is also housed in the exhaust groove portion 1216, so that it can detect the gas contamination introduced into the exhaust groove portion 1216. In a preferred embodiment of the present invention, the gas sensor 127 is a volatile organic compound sensor that detects information on carbon dioxide or total volatile organic compound gas, a formaldehyde sensor that detects information on formaldehyde gas, a bacteria sensor that detects information on bacteria or fungi, a virus sensor that detects information on virus gas, or a temperature and humidity sensor that detects information on the temperature and humidity of the gas.
[0035] The piezoelectric actuator 122 is housed in the square air-conducting assembly support region 1215 of the base 121. The air-conducting assembly support region 1215 communicates with the air supply groove portion 1214. When the piezoelectric actuator 122 operates, it sucks the gas in the air supply groove portion 1214 and causes the gas to flow into the piezoelectric actuator 122, and also causes the gas to flow into the exhaust groove portion 1216 through the ventilation hole 1215a of the air-conducting assembly support region 1215. The drive circuit board 123 covers the second surface 1212 of the base 121. The laser assembly 124 is installed on and electrically connected to the drive circuit board 123. The particulate sensor 125 is installed on and electrically connected to the drive circuit board 123. When the cover member 126 covers the base 121, the exhaust opening 1216a corresponds to the air supply opening 1214a of the base 121, and the exhaust port 1261b corresponds to the exhaust opening 1216a of the base 121.
[0036] The piezoelectric actuator 122 includes a jet hole sheet 1221, a cavity frame 1222, an actuator 1223, an insulating frame 1224, and a conductive frame 1225. The jet hole sheet 1221 is made of a flexible material and includes a floating sheet 1221a and a hollow hole 1221b. The floating sheet 1221a is a sheet-like structure capable of bending vibration, and its shape and dimensions are adapted to the inner edge of the air-conducting assembly support region 1215. The hollow hole 1221b penetrates the central portion of the floating sheet 1221a for the flow of gas. In a preferred embodiment of the present invention, the shape of the floating sheet 1221a is any one of a square, a circle, an ellipse, a triangle, or a polygon.
[0037] The above-described cavity frame 1222 is stacked on the jet hole sheet 1221, and its appearance corresponds to that of the jet hole sheet 1221. The actuator 1223 is stacked on the cavity frame 1222, and together with the cavity frame 1222 and the floating sheet 1221a, defines a resonance chamber 1226. The insulating frame 1224 is stacked on the actuator 1223, and its appearance is similar to that of the cavity frame 1222. The conductive frame 1225 is stacked on the insulating frame 1224, and its appearance is similar to that of the insulating frame 1224. The conductive frame 1225 includes a conductive pin 1225a and a conductive electrode 1225b. The conductive pin 1225a extends outward from the outer edge of the conductive frame 1225, and the conductive electrode 1225b extends inward from the inner edge of the conductive frame 1225.
[0038] Furthermore, the actuator 1223 includes a piezoelectric mounting plate 1223a, an adjustment resonance plate 1223b, and a piezoelectric plate 1223c. The piezoelectric mounting plate 1223a is stacked on the cavity frame 1222. The adjustment resonance plate 1223b is stacked on the piezoelectric mounting plate 1223a. The piezoelectric plate 1223c is stacked on the adjustment resonance plate 1223b. The adjustment resonance plate 1223b and the piezoelectric plate 1223c are housed within the insulating frame 1224. The conductive electrode 1225b of the conductive frame 1225 is electrically connected to the piezoelectric plate 1223c. In a preferred embodiment of the present invention, both the piezoelectric mounting plate 1223a and the adjustment resonance plate 1223b are made of a conductive material. The piezoelectric mounting plate 1223a includes a piezoelectric pin 1223d, and the piezoelectric pin 1223d and the conductive pin 1225a are connected to a drive circuit (not shown) on the drive circuit board 123 in order to receive a drive signal (e.g., drive frequency, drive voltage, etc.). As a result, the drive signal can be transmitted through a circuit composed of the piezoelectric pin 1223d, the piezoelectric mounting plate 1223a, the adjustment resonance plate 1223b, the piezoelectric plate 1223c, the conductive electrode 1225b, the conductive frame 1225, and the conductive pin 1225a. Also, the insulating frame 1224 blocks the conductive frame 1225 and the actuator 1223 to avoid a short circuit, so that the drive signal can be transmitted to the piezoelectric plate 1223c. After receiving the drive signal, the piezoelectric plate 1223c deforms due to the piezoelectric effect and can drive the piezoelectric mounting plate 1223a and the adjustment resonance plate 1223b to generate reciprocating bending vibrations.
[0039] Furthermore, the adjustment resonance plate 1223b is disposed between the piezoelectric plate 1223c and the piezoelectric mounting plate 1223a, and as a buffer material between the two, it can adjust the vibration frequency of the piezoelectric mounting plate 1223a. Basically, the thickness of the adjustment resonance plate 1223b is made thicker than that of the piezoelectric mounting plate 1223a. The vibration frequency of the actuator 1223 is adjusted by changing the thickness of the adjustment resonance plate 1223b. The jet hole sheet 1221, the cavity frame 1222, the actuator 1223, the insulating frame 1224, and the conductive frame 1225 are sequentially stacked and disposed within the air guiding assembly support region 1215. The piezoelectric actuator 122 is positioned within the air guiding assembly support region 1215. The piezoelectric actuator 122 defines a gap 1221c between the floating sheet 1221a and the inner edge of the air guiding assembly support region 1215 for gas to flow through.
[0040] A gas flow chamber 1227 is formed between the blower hole sheet 1221 and the bottom surface of the air guide assembly support area 1215. The gas flow chamber 1227 communicates with the resonant chamber 1226 between the actuator 1223, the blower hole sheet 1221, and the floating sheet 1221a through the hollow hole 1221b of the blower hole sheet 1221. When the vibration frequency of the gas in the resonant chamber 1226 is made to match the vibration frequency of the floating sheet 1221a, the resonant chamber 1226 and the floating sheet 1221a generate the Helmholtz resonance phenomenon, so that the transport efficiency of the gas can be improved. When the piezoelectric plate 1223c moves in a direction away from the bottom surface of the air guide assembly support area 1215, the piezoelectric plate 1223c drives the floating sheet 1221a of the blower hole sheet 1221 to move in a direction away from the bottom surface of the air guide assembly support area 1215. As a result, the volume of the gas flow chamber 1227 expands rapidly, the internal pressure drops, generating a negative pressure, and the gas outside the piezoelectric actuator 122 is sucked in through the gap 1221c, and then flows into the resonating chamber 1226 through the hollow hole 1221b, so that the air pressure in the resonating chamber 1226 can create a pressure gradient. When the piezoelectric plate 1223c drives the floating sheet 1221a of the blowhole sheet 1221 to move it to the bottom surface of the air guide assembly support area 1215, the gas in the resonating chamber 1226 flows out rapidly through the hollow hole 1221b, and the gas in the gas flow chamber 1227 is compressed. The compressed gas becomes close to an ideal gas according to Bernoulli's law, and is rapidly and in large quantities introduced or discharged to the vent hole 1215a of the air guide assembly support area 1215.
[0041] 9B and 9C are repeated, the piezoelectric plate 1223c vibrates back and forth, and according to the principle of inertia, the air pressure inside the resonating chamber 1226 after exhaust is lower than the equilibrium air pressure, so that the gas can be reintroduced into the resonating chamber 1226. The vibration frequency of the gas in the resonating chamber 1226 is controlled to be the same as the vibration frequency of the piezoelectric plate 1223c, thereby generating the Helmholtz resonance phenomenon and achieving high-speed and large-volume transport of the gas.
[0042] As shown in FIGS. 10A to 10C, the gas flows in from the air supply port 1261a of the cover member 126, flows into the air supply groove portion 1214 of the base 121 through the air supply opening 1214a, and reaches the position of the particulate sensor 125. The continuous driving of the piezoelectric actuator 122 sucks the gas in the air supply path, so that the external gas is quickly introduced and stably circulated and passes above the particulate sensor 125. The light beam emitted from the laser assembly 124 passes through the light transmission window 1214b and enters the air supply groove portion 1214. When the air supply groove portion 1214 passes above the particulate sensor 125, the light beam of the particulate sensor 125 irradiates the suspended particles in the gas, forming a light scattering phenomenon and a particulate projection. The particulate sensor 125 detects the particulate projection generated by the light scattering and can calculate information such as the particle size and quantity of the suspended particles contained in the gas. The gas above the particulate sensor 125 is continuously driven by the piezoelectric actuator 122, introduced into the vent hole 1215a of the air guide assembly support region 1215, and flows into the exhaust groove portion 1216. Finally, even after the gas enters the exhaust groove portion 1216, the piezoelectric actuator 122 continuously transports the gas to the exhaust groove portion 1216, so that the gas in the exhaust groove portion 1216 is pushed out to the outside through the exhaust opening 1216a and the exhaust port 1261b.
[0043] As described above, in the present invention, as shown in FIGS. 11 and 12, a plurality of in-vehicle gas detection modules 1a, a plurality of out-of-vehicle gas detection modules 1b, a vehicle body gas air-conditioning control device 2, and a plurality of filtration and purification assemblies D are arranged in the vehicle.

Thereby, a state in which clean and complete breathing can be performed in the vehicle A can be formed.
