[0002] With the rapid development of the world's population and industry, air quality is gradually deteriorating. People who are exposed to these harmful air pollution gases for a long time are not only harmful to human health, but in severe cases, it can even be life-threatening.

[0003] When the air contains a lot of pollutants, such as carbon dioxide, carbon monoxide, formaldehyde, bacteria, fungi, volatile organic compounds (VOCs), suspended particulates, or ozone, and the concentration of the pollutants increases, it is harmful to the human body. For example, in the case of suspended particulates, such particles can penetrate the alveoli and circulate throughout the body with the blood. This not only harms the respiratory tract, but can also cause cardiovascular diseases and increase the risk of cancer.

[0004] In today's world, epidemic diseases such as influenza and pneumonia are widespread, threatening people's health, and as a result, people's social activities are also restricted, and people go out to use public transportation less frequently, and when people go out, they use their own cars as a means of transportation and drive themselves. Therefore, how to ensure that the gas inside the car is always clean and safe for people to breathe when driving a car is an important research and development topic of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] The embodiments embodying the features and advantages of the present invention will be described in detail in the following. The present invention can be modified in various ways, and all such modifications do not depart from the scope of the present invention. In addition, the description and drawings in this specification are for the purpose of explaining the present invention, and are not intended to limit the present invention.

[0009] As shown in FIGS. 1 to 12B, the present invention is an air pollution prevention and control method suitable for filtering and exchanging gaseous pollution in a vehicle interior space, which specifically includes the following steps:

[0010] (Step S1) Provide an external gas detector 1a, detect external gas pollution, and transmit external gas detection data. As shown in Fig. 2A, the external gas detector 1a is installed outside a vehicle, and the external gas detector 1a includes a gas detection module and is used to detect external gas pollution and transmit external gas detection data.

[0011] (Step S2) Provide an interior gas detector 1b, detect gas pollution in the interior space of the vehicle, and transmit interior gas detection data. As shown in FIG. 2B, the interior gas detector 1b is installed inside the vehicle, and the interior gas detector 1b includes a gas detection module and is used to detect gas pollution in the vehicle and transmit interior gas detection data. The exterior gas detector 1a of this embodiment has the same structure as the interior gas detector 1b, but the present invention is not limited thereto.

[0012] (Step S3) Provide the vehicle interior gas exchange system 2 and control the introduction or non-introduction of the gas outside the vehicle into the vehicle interior space. The vehicle interior gas exchange system 2 includes a purification unit 23 and a control drive unit 25. The purification unit 23 filters and purifies gas pollution in the vehicle interior space, and the control drive unit 25 is used to receive and compare the outside gas detection data and the inside gas detection data. As shown in FIG. 2A to FIG. 2E, the vehicle interior gas exchange system 2 includes at least one intake port 21 and at least one exhaust port 22. The vehicle interior gas exchange system 2 further includes the purification unit 23, an air conditioning unit 24, and a control drive unit 25. The purification unit 23 filters and purifies the gas introduced by the intake port 21, and then introduces the gas into the vehicle interior space through the exhaust port 22. The air conditioning unit 24 adjusts the temperature and humidity of the vehicle interior space. The control drive unit 25 receives the outside gas detection data and the inside gas detection data, performs calculations and comparisons with the artificial intelligence, and controls the operation and operation time of the inside gas exchange system 2. The intake port 21 is connected to the intake passage 211, and the intake port 21 is provided with an intake valve 212 for controlling the opening and closing of the intake port 21 to promote the introduction of outside gas. The exhaust port 22 is connected to a blower 221 to discharge gas through the exhaust port 22. The inside gas exchange system 2 includes a ventilation air in port 26, a ventilation passage 27, and a ventilation air out port 28, and the ventilation air in port 26 is connected to the ventilation passage 27, the ventilation passage 27 is connected to the ventilation air out port 28, and is connected to the intake passage 211 to form a circulation gas flow path. The ventilation air out port 28 is provided with an outlet valve 29 for controlling the opening and closing of the ventilation air out port 28 to control the discharge of gas from the ventilation air out port 28.

[0013] (Step S4) The control and driving unit 25 compares the outside gas detection data with the inside gas detection data, and then provides the artificial intelligence selection for the inside gas exchange system 2 to introduce the outside gas, and also filters the gas pollution in the inside space and exchanges it to the outside, so as to form a state where the inside space can be clean and safe to breathe. The control and driving unit 25 of the inside gas exchange system 2 provides the artificial intelligence calculation to compare the outside gas detection data with the inside gas detection data, and provides the artificial intelligence selection for the inside gas exchange system 2 to introduce the outside gas, and selects the filtering and exchange of the gas pollution in the inside space, that is, whether to directly filter the gas pollution in the inside space and exchange it to the outside, or whether to introduce the outside gas through the air intake 21 to filter and exchange the gas pollution in the inside space, so as to perform the exchange and filtering of the gas pollution in the inside space, and form a state where the inside space can be clean and safe to breathe.

[0014] According to the above method, the vehicle interior gas exchange system 2 provided by the present invention can intelligently select the gas exchange in the vehicle interior space, and adjust the vehicle interior detection data of the vehicle interior gas pollution to a safe detection value, so that clean and safe gas can be breathed in the vehicle interior space. The device and processing method of the present invention will be described in detail below.

[0015] The above-mentioned outside gas detection data and inside gas detection data are data detected from gas pollution. The gas pollution is airborne fine particles (PM1, PM 2.5 , P.M. 10 ), carbon monoxide (CO), carbon dioxide (CO2), ozone (O3), sulfur dioxide (SO2), nitrogen dioxide (NO2), lead (Pb), total volatile organic compounds (TVOC), formaldehyde (HCHO), bacteria, and viruses, or a combination thereof. The present invention is not limited thereto.

[0016] As shown in FIG. 3 and FIG. 12A to FIG. 12B, the outside gas detector 1a and the inside gas detector 1b further include a gas detection module. The gas detection module includes a control circuit board 11, a gas detection main body 12, a microprocessor 13, and a communication device 14. The gas detection main body 12, the microprocessor 13, and the communication device 14 are packaged in the control circuit board 11 to form an integrated unit, and are electrically connected to each other. The microprocessor 13 and the communication device 14 are installed on the control circuit board 11. The microprocessor 13 controls the detection operation of the gas detection main body 12. The gas detection main body 12 detects gas pollution and outputs a detection signal. The microprocessor 13 receives the detection signal, performs calculations and processing, and then outputs a signal. Thus, the microprocessor 13 of the gas detection module of the outside gas detector 1a and the inside gas detector 1b generates outside gas detection data and inside gas detection data, and provides the generated data to the communicator 14 for external communication. More specifically, the communicator 14 connects and transmits / receives signals with the control and drive unit 25 of the inside gas exchange system 2, and based on the outside gas detection data and inside gas detection data transmitted from the communicator 14, the control and drive unit 25 performs calculations and comparisons using artificial intelligence to control the operation and operation time of the inside gas exchange system 2, and selects whether to use the purification unit 23 to adjust the gas pollution to a safe detection value, select the gas pollution in the inside space of the vehicle by artificial intelligence and control it to be exchanged with the outside of the vehicle, or introduce the gas outside the vehicle through the air intake 21 to exchange it with the gas pollution in the inside space of the vehicle, thereby exchanging the gas pollution in the inside space of the vehicle to create a clean and safe state for breathing. The communication device 14 transmits and receives data to and from the outside via wired communication such as USB, mini-USB, micro-USB, etc., or wireless communication such as Wi-Fi, Bluetooth (registered trademark) communication, radio frequency identification communication, and near field communication.

[0017] The above-mentioned gas detector 1b inside the vehicle operates in the vehicle interior space, and the gas detector 1b inside the vehicle may be fixed in the vehicle interior space (for example, the position shown in FIG. 2B), or the gas detector 1b inside the vehicle may be a mobile detection device. In an embodiment of the present invention, the gas detector 1b inside the vehicle may be a device (not shown) that can be directly worn by a person, such as a watch or a bracelet. In this case, whenever a person is in the vehicle, gas pollution in the vehicle interior space can be detected and gas detection data inside the vehicle can be transmitted. In another embodiment, the gas detector 1b inside the vehicle may be a device (not shown) that can be directly carried by a person, such as a mobile phone. In this case, whenever a person is in the vehicle interior space, gas pollution in the vehicle interior space can be detected and gas detection data inside the vehicle can be transmitted and gas pollution data inside the vehicle can be recorded. When the gas detector 1b inside the vehicle of the present invention is a mobile detection device, the communicator 14 of the gas detection module of the gas detector 1b inside the vehicle adopts a wireless communication format.

[0018] As shown in FIGS. 4A to 6, the gas detection main body 12 includes a base 121, a piezoelectric actuator 122, a drive circuit board 123, a laser assembly 124, a particle sensor 125, a gas sensor 127 and an outer cover 126.

[0019] The base 121 includes a first surface 1211, a second surface 1212, a laser installation area 1213, an air-in groove 1214, an air guide assembly mounting area 1215, and an air-out groove 1216. The first surface 1211 and the second surface 1212 are two surfaces arranged opposite each other. The laser installation area 1213 is formed hollow from the first surface 1211 toward the second surface 1212. The outer cover 126 covers the base 121 and includes a side plate 1261, and the side plate 1261 includes an intake opening 1261a and an exhaust opening 1261b. The air-in groove 1214 is provided to recess the second surface 1212 and is provided adjacent to the laser installation area 1213. The air-in groove 1214 is provided with an intake port 1214a which is connected to the outside of the base 121 and corresponds to the intake opening 1261a of the outer cover 126, and both side walls of the air-in groove 1214 are provided with light-transmitting windows 1214b which are connected to the laser installation area 1213. Thus, the first surface 1211 of the base 121 is covered by the outer cover 126, and the second surface 1212 is covered by the drive circuit board 123, so that the air-in groove 1214 defines an air-in path.

[0020] The air guide assembly mounting area 1215 is formed by recessing the second surface 1212, communicates with the air-in groove 1214, and has a vent hole 1215a on the bottom surface. Positioning block members 1215b are provided at the four corners of the air guide assembly mounting area 1215. An exhaust port 1216a is provided in the air-out groove 1216, and the exhaust port 1216a is installed to correspond to the exhaust opening 1261b of the outer cover 126. The air-out groove 1216 includes a first region 1216b formed by recessing the first surface 1211 with respect to the vertical projection region of the air guide assembly mounting area 1215, and a second region 1216c formed by hollowing out from the first surface 1211 to the second surface 1212 in a region extending from the vertical projection region of the air guide assembly mounting area 1215. The first region 1216b is connected to the second region 1216c and forms a step. The first region 1216b of the air-out groove 1216 communicates with the vent hole 1215a of the air guide assembly mounting area 1215, and the second region 1216c of the air-out groove 1216 communicates with the exhaust port 1216a. Thus, when the first surface 1211 of the base 121 is covered by the outer cover 126 and the second surface 1212 is covered by the driving circuit board 123, the air-out groove 1216 and the driving circuit board 123 define an air-out path.

[0021] The laser assembly 124, the particle sensor 125, and the gas sensor 127 are provided on the driving circuit board 123 so as to be electrically connected, and are positioned in the base 121. In order to clearly explain the positions of the laser assembly 124, the particle sensor 125, the gas sensor 127, and the base 121, the driving circuit board 123 is omitted in FIG. 6. The laser assembly 124 is accommodated in the laser installation area 1213 of the base 121, and the particle sensor 125 is accommodated in the air-in groove 1214 of the base 121 and aligned with the laser assembly 124. The laser assembly 124 is installed to correspond to the light transmission window 1214b. The light transmission window 1214b is used so that the laser light emitted by the laser assembly 124 passes through and is irradiated to the air-in groove 1214. The beam path of the laser light emitted by the laser assembly 124 passes through the light transmission window 1214b and is perpendicular to the air-in groove 1214. The beam path of the laser light emitted by the laser assembly 124 passes through the light-transmitting window 1214b and irradiates the air-in groove 1214, and the gas in the air-in groove 1214 is irradiated. When the beam comes into contact with the gas, the laser light is scattered to form a projected light spot. The particulate sensor 125 is disposed at an orthogonal position, senses the projected light spot formed by scattering, and performs calculations to obtain gas detection data. The particulate sensor 125 detects suspended particulates (PM1, PM 2.5 , P.M. 10 ) information. The gas sensor 127 is disposed so as to be electrically connected on the driving circuit board 123, and is housed in the air-out groove 1216, and is used to detect gas introduced into the air-out groove 1216. In a specific embodiment of the present invention, the gas sensor 127 includes a volatile organic sensor that detects information on carbon dioxide (CO2) or total volatile organic compounds (TVOC) gas, a formaldehyde sensor that detects information on formaldehyde (HCHO) gas, a bacteria sensor that detects bacteria and fungi, and a virus sensor that detects information on virus gas.

[0022] As shown in FIG. 8A to FIG. 9C, the piezoelectric actuator 122 includes a blowhole sheet 1221, a cavity frame 1222, an actuator 1223, an insulating frame 1224, and a conductive frame 1225. The blowhole sheet 1221 is made of a flexible material and includes a suspension plate 1221a and a hollow hole 1221b. The suspension plate 1221a is a bending vibration sheet-like structure, and its shape and dimensions correspond to the inner edge of the air guide assembly mounting area 1215. The hollow hole 1221b is provided through the center of the suspension plate 1221a for gas circulation. In a preferred embodiment of the present invention, the shape of the suspension plate 1221a is any one of, but not limited to, a square, a figure, an ellipse, a triangle, or a polygon. The cavity frame 1222 is arranged to be stacked on the blowhole sheet 1221, and its appearance corresponds to the blowhole sheet 1221. The actuator 1223 is stacked on the cavity frame 1222 to form a resonant cavity 1226 between the cavity frame 1222 and the suspension plate 1221a. The insulating frame 1224 is stacked on the actuator 1223 and has a similar appearance to the cavity frame 1222. The conductive frame 1225 is stacked on the insulating frame 1224 and has a similar appearance to the insulating frame 1224, and the conductive frame 1225 includes a conductive pin 1225a and a conductive electrode 1225b, where the conductive pin 1225a extends from the conductive frame 1225 to the outer edge. The conductive electrode 1225b extends from the conductive frame 1225 to the inner edge. The actuator 1223 includes a piezoelectric carrier plate 1223a, a tuned resonant plate 1223b, and a piezoelectric plate 1223c. Piezoelectric carrier plate 1223a is arranged stacked on cavity frame 1222, tuned resonant plate 1223b is arranged stacked on piezoelectric carrier plate 1223a, and piezoelectric plate 1223c is arranged stacked on tuned resonant plate 1223b, and tuned resonant plate 1223b and piezoelectric plate 1223c are housed in insulating frame 1224 and electrically connected to piezoelectric plate 1223c by conductive electrode 1225b of conductive frame 1225.In a preferred embodiment of the present invention, the piezoelectric carrier plate 1223a and the adjusted resonant plate 1223b are made of conductive material. The piezoelectric carrier plate 1223a includes a piezoelectric pin 1223d, and the piezoelectric pin 1223d and the conductive pin 1225a are connected to a driving circuit (not shown) of the driving circuit board 123 to receive a driving signal (driving frequency or driving voltage). The driving signal forms a loop through the piezoelectric pin 1223d, the piezoelectric carrier plate 1223a, the adjusted resonant plate 1223b, the piezoelectric plate 1223c, the conductive electrode 1225b, the conductive frame 1225, and the conductive pin 1225a. The insulating frame 1224 can isolate the conductive frame 1225 from the actuator 1223 to avoid short circuiting. This allows the driving signal to be transmitted to the piezoelectric plate 1223c. After the piezoelectric plate 1223c receives the driving signal, it is deformed by the piezoelectric effect, which drives the piezoelectric carrier plate 1223a and the adjusted resonating plate 1223b to perform reciprocating bending vibration.

[0023] The adjusted resonant plate 1223b is disposed between the piezoelectric plate 1223c and the piezoelectric carrier plate 1223a, and is used as a buffer between them, so that the vibration frequency of the piezoelectric carrier plate 1223a can be adjusted. Basically, the thickness of the adjusted resonant plate 1223b is thicker than that of the piezoelectric carrier plate 1223a, and the vibration frequency of the actuator 1223 can be adjusted by changing the thickness of the adjusted resonant plate 1223b.

[0024] As shown in Figures 7A, 7B, 8A, 8B and 9A, the piezoelectric actuator 122 includes a blow hole sheet 1221, a cavity frame 1222, an actuator 1223, an insulating frame 1224 and a conductive frame 1225, which are stacked in order. The piezoelectric actuator 122 is accommodated in a square air guide assembly mounting area 1215 on the base 121, and is supported and positioned by a positioning block member 1215b. The outside of the piezoelectric actuator 122 is surrounded by a gap 1221c for gas circulation. That is, the piezoelectric actuator 122 is surrounded by a gap 1221c defined between the suspension plate 1221a and the inner edge of the air guide assembly mounting area 1215. A resonant cavity 1226 is formed between the actuator 1223, the cavity frame 1222 and the suspension plate 1221a. An airflow cavity 1227 is formed between the blower hole sheet 1221 and the bottom surface of the air guide assembly mounting area 1215. The airflow cavity 1227 is connected to the resonant cavity 1226 between the actuator 1223, the cavity frame 1222, and the suspension plate 1221a through the hollow hole 1221b of the blower hole sheet 1221. This makes the vibration frequency of the gas passing through the resonant cavity 1226 tend to be the same as the vibration frequency of the suspension plate 1221a, promoting the Helmholtz resonance effect between the resonant cavity 1226 and the suspension plate 1221a, and improving the gas transport efficiency.

[0025] 9B, when the piezoelectric plate 1223c moves away from the bottom surface of the air guide assembly mounting area 1215, the piezoelectric plate 1223c drives the suspension plate 1221a of the blower hole sheet 1221 to move away from the bottom surface of the air guide assembly mounting area 1215. This causes the volume of the airflow cavity 1227 to expand rapidly, the internal pressure to decrease and generate negative pressure, and the gas outside the piezoelectric actuator 122 flows in through the gap 1221c and enters the resonant cavity 1226 through the hollow hole 1221b, increasing the air pressure in the resonant cavity 1226 and generating a pressure gradient.

[0026] As shown in FIG. 9C, when the suspension plate 1221a of the blower sheet 1221 moves toward the bottom surface of the air guide assembly mounting area 1215 by driving the piezoelectric plate 1223c, the gas in the resonant cavity 1226 rapidly flows out through the hollow hole 1221b, and the gas in the air flow cavity 1227 is compressed. The compressed gas is rapidly and massively ejected into the air vent 1215a of the air guide assembly mounting area 1215 in an ideal gas state close to Bernoulli's law.

[0027] The air guide assembly mounting area 1215 of the base 121 is connected to the air-in groove 1214. The piezoelectric actuator 122 is accommodated in the square air guide assembly mounting area 1215 on the base 121. The driving circuit board 123 covers the second surface 1212 of the base 121. The laser assembly 124 is mounted on and electrically connected to the driving circuit board 123. The particle sensor 125 is mounted on and electrically connected to the driving circuit board 123. Thus, the outer cover 126 covers the base 121, the exhaust port 1216a corresponds to the intake port 1214a of the base 121, and the exhaust opening 1261b corresponds to the exhaust port 1216a of the base 121. When the piezoelectric actuator 122 repeats the operations shown in Figures 9B and 9C, the piezoelectric plate 1223c vibrates back and forth, and according to the principle of inertia, the air pressure inside the resonant cavity 1226 after exhaust is lower than the equilibrium air pressure, so the gas re-enters the resonant cavity 1226, and the vibration frequency of the gas in the resonant cavity 1226 becomes the same as the vibration frequency of the piezoelectric plate 1223c, generating the Helmholtz resonance effect and realizing rapid and large-scale gas transport.

[0028] As shown in FIG. 10A, the gas outside the gas detection module enters through the intake opening 1261a of the outer cover 126, passes through the intake port 1214a, and flows into the intake path defined by the air-in groove 1214 of the base 121, and flows to the position of the particle sensor 125. At the same time, the piezoelectric actuator 122 is continuously driven, so that the gas in the intake path is sucked. This allows the gas outside the gas detection module to flow quickly and stably and pass above the particle sensor 125. As shown in FIG. 10B, the beam of laser light emitted by the laser assembly 124 at this time enters the air-in groove 1214 through the light transmission window 1214b and passes above the particle sensor 125. When the beam of the particle sensor 125 irradiates the suspended particles in the gas, a scattering phenomenon occurs and a projected light spot can be formed. The particle sensor 125 can perform calculations based on the projected light spot generated by scattering to obtain related information such as the particle size and concentration of the suspended particles contained in the gas. The gas above the particle sensor 125 is continuously driven by the piezoelectric actuator 122, and is introduced into the vent hole 1215a of the air guide assembly mounting area 1215, and enters the air-out groove portion 1216. Finally, as shown in Fig. 10C, when the gas enters the air-out groove portion 1216, it is detected by the gas sensor 127. Since the piezoelectric actuator 122 continuously transports the gas to the air-out groove portion 1216, the gas in the air-out groove portion 1216 is pushed out through the exhaust port 1216a and the exhaust opening 1261b, and finally discharged to the outside.

[0029] The outside gas detector 1a and the inside gas detector 1b of the present invention suck up gas pollution outside the outside gas detector 1a and the inside gas detector 1b using a gas detection module installed inside, which enters the intake path defined in the air-in groove portion 1214 through the intake opening 1261a, and the particulate matter concentration of particulate matter contained in the gas pollution is detected by the particulate matter sensor 125.Then, by the piezoelectric actuator 122, the particulate matter enters the air-out path defined in the air-out groove portion 1216 through the air vent 1215a of the air guide assembly mounting area 1215, is detected by the gas sensor 127, and finally is discharged from the exhaust port 1216a of the base 121 to the exhaust opening 1261b. This allows the gas detection module to not only detect suspended particles in the gas, but also detect gas pollution, for example, for one or a combination of gases selected from the group consisting of carbon monoxide (CO), carbon dioxide (CO2), ozone (O3), sulfur dioxide (SO2), nitrogen dioxide (NO2), lead (Pb), total volatile organic compounds (TVOC), formaldehyde (HCHO), bacteria, and viruses.

[0030] As shown in FIG. 11, the control drive unit 25 receives the outside gas detection data of the outside gas detector 1a and the inside gas detection data of the inside gas detector 1b. When the inside gas detection data is higher than the safe detection value, as shown in FIG. 2C, the control drive unit 25 closes the intake valve 212 and the outlet valve 29, and at the same time operates the blower 221, so that the gas pollution in the inside space of the vehicle enters the ventilation passage 27 through the ventilation air inlet 26, and then is introduced into the intake passage 211 to form a circulating gas flow path, so that the gas pollution is filtered and purified by the purification unit 23, and is discharged into the inside space 101 through the exhaust port 22. This reduces the inside detection data detected by the gas pollution in the inside space of the vehicle to a safe detection value. As shown in FIG. 11, the control drive unit 25 receives the outside gas detection data and the inside gas detection data. When the outside gas detection data is lower in gas pollution than the inside gas detection data, as shown in FIG. 2D, the control drive unit 25 opens the intake valve 212 and the outlet valve 29, and at the same time operates the blower 221, so that the outside gas is introduced into the intake passage 211, and after being filtered and purified by the purification unit 23, it is introduced into the interior space through the exhaust port 22. The gas pollution in the interior space passes through the ventilation air in port 26 and enters the ventilation passage 27, and is then discharged outside the vehicle through the ventilation air out port 28. As a result, the gas pollution in the interior space is discharged outside the vehicle, and the interior detection data detected by the gas pollution in the interior space is reduced to a safe detection value.

[0031] As shown in FIG. 11, the control drive unit 25 receives the outside gas detection data and the inside gas detection data, and when the inside gas detection data is lower in gas pollution than the outside gas detection data, as shown in FIG. 2E, the control drive unit 25 closes the intake valve 212 and opens the outlet valve 29 to prevent the introduction of gas outside the vehicle. At the same time, the blower 221 is operated, and the gas pollution in the vehicle interior space enters the ventilation passage 27 through the ventilation air in port 26 and is discharged outside the vehicle through the ventilation air out port 28. At the same time, the gas pollution is introduced into the intake passage 211 to form a circulating gas flow path, and the gas pollution passes through the purification unit 23 for filtering and purification, and finally is discharged into the vehicle interior space through the exhaust port 22. As a result, the gas pollution in the vehicle interior space is ventilated and filtered, so that the inside detection data detected by the gas pollution in the vehicle interior space is reduced to a safe detection value.

[0032] The above safety detection value is for suspended particulate matter 2.5 (PM 2.5 ) at a concentration of 10 μg / m 3 carbon dioxide (CO2) concentration is less than 1000 ppm, total volatile organic compounds (TVOC) concentration is less than 0.56 ppm, formaldehyde (HCHO) concentration is less than 0.08 ppm, and bacterial count is 1500 CFU / m 3 Less than 1000 CFU / m 3 less than 0.075 ppm, sulfur dioxide concentration less than 0.1 ppm, carbon monoxide concentration less than 35 ppm, ozone concentration less than 0.12 ppm, lead concentration less than 0.15 μg / m 3 This includes being less than.

As a result, gas molecules such as volatile formaldehyde, toluene, and volatile organic compounds (VOCs) contained in the gaseous pollution can be decomposed into water and carbon dioxide, thereby achieving the effects of filtering and purification.

[0036] In another embodiment, the purification unit 23 may be configured by a high-efficiency filter 23a equipped with a negative ion unit 23d.

The gaseous pollutants introduced through the intake passage 211 are electrolyzed by the plasma to convert oxygen molecules and water molecules contained in the gaseous pollutants into cations (H + ) and anion (O 2- ) and the substances with water molecules attached around the ions are attached to the surface of viruses and bacteria, and then under the action of chemical reactions, they are converted into highly oxidatively active reactive oxygen species (hydroxyl, OH group), which abstract the hydrogen atoms from the surface proteins of viruses and bacteria, oxidize and culture them, and filter the introduced gaseous pollution, thereby achieving the effect of filtration and purification.
