[0007] Embodiments showing the features and advantages of the present invention will be described in detail in the following description. 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.

[0008] Refer to FIGS. 1A and 1B. The present invention provides a purification and prevention system that is suitable for installation in an indoor space and approaches zero indoor air pollution. The system includes a plurality of gas detection devices A, a central control and monitoring device B, and a plurality of air exchange and filtration devices C. The plurality of gas detection devices A detect the nature and concentration of air pollution and output indoor air pollution data and outdoor air pollution data. The central control and monitoring device B receives the outdoor air pollution data and the indoor air pollution data, performs intelligent calculation and comparison, identifies the location and area of air pollution in the indoor space, intelligently issues a control command, and transmits it through wireless communication. The plurality of air exchange and filtration devices C receive the control command and start, and filter and exchange the air pollution by the plurality of air exchange and filtration devices C until the indoor air pollution data detected by the plurality of gas detection devices A reaches the safety detection value, thereby quickly removing the air pollution so as to approach zero, and reaching a state where the air in the indoor space is clean and breathable. Air pollution refers to any one or a combination of suspended particulate matter, carbon monoxide, carbon dioxide, ozone, sulfur dioxide, nitrogen dioxide, lead, total volatile organic compounds, formaldehyde, bacteria, fungi, and viruses.

[0009] The above-mentioned plurality of gas detection devices A include at least one outdoor gas detector A0 and at least one indoor gas detector A1. The outdoor gas detector A0 detects the nature and concentration of air pollution and outputs outdoor air pollution data, and the indoor gas detector A1 detects the nature and concentration of air pollution and outputs indoor air pollution data. The output of the outdoor air pollution data and the indoor air pollution data is transmission by wireless communication. The wireless communication is any one of a Wi-Fi module, a Bluetooth (registered trademark) module, a radio frequency identification module, and a near-field communication module.

[0010] The above central control and monitoring device B receives outdoor air pollution data and indoor air pollution data through wireless communication, performs intelligent calculation and comparison, identifies the location and area of air pollution in the indoor space, and issues control commands intelligently and selectively. The wireless communication is any one of a Wi-Fi module, a Bluetooth (registered trademark) module, a radio frequency identification module, and a near field communication module.

[0011] Each of the above air exchange and filtration devices C includes at least one air guiding device 1 and at least one filtration component 2. The air exchange and filtration device C is combined with a smart switch D. The smart switch D receives the control command, controls the startup operation of at least one air guiding device 1, and filters and exchanges air pollution by the filtration component 2 until the indoor air pollution data detected by the plurality of gas detection devices A reaches the safety detection value, thereby quickly removing the air pollution so as to approach zero, and making the air in the indoor space reach a clean and breathable state. The safety detection values include that the concentration of fine particulate matter 2.5 (PM 2.5 ) is less than 15 μg / m 3 , the concentration of carbon dioxide (CO2) is less than 1000 ppm, the concentration of total volatile organic compounds (TVOC) is less than 0.56 ppm, the concentration of formaldehyde (HCHO) is less than 0.08 ppm, the number of bacteria is less than 1500 CFU / m 3 , the number of fungi is less than 1000 CFU / m 3 , the concentration of sulfur dioxide is less than 0.075 ppm, the concentration of nitrogen dioxide is less than 0.1 ppm, the concentration of carbon monoxide is less than 9 ppm, the concentration of ozone is less than 0.06 ppm, and the concentration of lead is less than 0.15 μg / m 3 .

[0012] The above-mentioned outdoor gas detector A0 and indoor gas detector A1 can be, for example, gas detection devices A with the same structure, but are not limited thereto. Hereinafter, the gas detection device A will be described using the reference numeral 3. The gas detection device 3 may be in the form of a gas detection device 3 including an external power supply terminal 35 as shown in FIGS. 2A and 2B. The external power supply terminal 35 is formed integrally with the control circuit board 31 and protrudes outside the outer shell. In another embodiment, the gas detection device 3 may be in the form of a gas detection device 3 without an external power supply terminal as shown in FIG. 2C.

[0013] The gas detection device 3 includes a control circuit board 31, a gas detection body 32, a microprocessor 33, and a communicator 34. The gas detection body 32, the microprocessor 33, and the communicator 34 are packaged on the control circuit board 31, integrally formed, and electrically connected. The microprocessor 33 controls the detection operation of the gas detection body 32. The gas detection body 32 detects air pollution and outputs a detection signal. The microprocessor 33 receives the detection signal, performs arithmetic processing and output, forms air pollution data, provides it to the communicator 34, and transmits and outputs it externally through wireless communication. In this embodiment, the communicator 34 outputs indoor air pollution data or outdoor air pollution data through wireless communication transmission and transmits it to the central control and monitoring device B (as shown in FIG. 11). The communicator 34 outputs indoor air pollution data or outdoor air pollution data through wireless communication transmission, and the wireless communication may be any one of a Wi-Fi module, a Bluetooth (registered trademark) module, a radio frequency identification module, and a near field communication module.

[0014] Refer to FIGS. 4A to 10C. The gas detection body 32 includes a base 321, a piezoelectric actuator 322, a drive circuit board 323, a laser component 324, a particulate sensor 325, and an outer lid 326. The base 321 has a first surface 3211, a second surface 3212, a laser installation region 3213, an intake groove 3214, a conductive component mounting region 3215, and an exhaust groove 3216. The first surface 3211 and the second surface 3212 are two opposed surfaces. The laser installation region 3213 is formed by being hollowed out from the first surface 3211 toward the second surface 3212. Further, the outer lid 326 covers the base 321 and has a side plate 3261 provided with an intake frame opening 3261a and an exhaust frame opening 3261b. The intake groove 3214 is formed by being recessed from the second surface 3212 and is adjacent to the laser installation region 3213. An intake through hole 3214a that communicates with the outside of the base 321 and corresponds to the intake frame opening 3261a of the outer lid 326 is provided in the intake groove 3214, and both side walls of the intake groove 3214 are penetrated by a light transmission window 3214b and communicate with the laser installation region 3213. Therefore, by covering the first surface 3211 of the base 321 with the outer lid 326 and covering the second surface 3212 with the drive circuit board 323, an intake path is defined by the intake groove 3214.

[0015] The air guiding component mounting area 3215 is formed to be recessed from the second surface 3212, communicates with the intake groove 3214, has ventilation holes 3215a penetrating through the bottom surface, and has positioning protrusions 3215b at the four corners of the air guiding component mounting area 3215 respectively. An exhaust vent 3216a corresponding to the exhaust frame opening 3261b of the outer cover 326 is provided in the exhaust groove 3216. The exhaust groove 3216 includes a first section 3216b formed to be recessed in the vertical projection area of the first surface 3211 onto the air guiding component mounting area 3215, and a second section 3216c formed by being cut out from the first surface 3211 towards the second surface 3212 in an area extending from the vertical projection area of the air guiding component mounting area 3215. The first section 3216b of the exhaust groove 3216 is connected to the second section 3216c so as to form a step. The first section 3216b of the exhaust groove 3216 communicates with the ventilation hole 3215a of the air guiding component mounting area 3215, and the second section 3216c of the exhaust groove 3216 communicates with the exhaust vent 3216a. Therefore, when the first surface 3211 of the base 321 is covered by the outer cover 326 and the second surface 3212 is covered by the drive circuit board 323, an exhaust path is defined by both the exhaust groove 3216 and the drive circuit board 323.

[0016] The above laser component 324 and the particulate sensor 325 are both installed on the drive circuit board 323 and are located within the base 321. To clearly explain the positions of the laser component 324 and the particulate sensor 325 and the base 321, the drive circuit board 323 is intentionally omitted. The laser component 324 is housed within the laser installation region 3213 of the base 321, and the particulate sensor 325 is housed within the intake groove 3214 of the base 321 and is aligned with the laser component 324. Also, by the laser component 324 corresponding to the light transmission window 3214b through which the laser light emitted by the laser component 324 passes, the laser light irradiates the intake groove 3214. The beam path emitted by the laser component 324 passes through the light transmission window 3214b and forms a direction perpendicular to the intake groove 3214. The beam emitted by the laser component 324 enters the intake groove 3214 through the light transmission window 3214b, irradiates the gas within the intake groove 3214, and when the beam contacts the gas, it scatters to generate a projection spot. The particulate sensor 325 is located at the orthogonal direction position and receives the projection spot due to scattering and performs calculations to obtain gas detection data. Also, the gas sensor 327 is positioned and installed on the drive circuit board 323 and is electrically connected, is housed within the intake groove 3214, and detects air pollution introduced into the intake groove 3214. In a preferred embodiment of the present invention, the gas sensor 327 is a volatile organic compound sensor that detects gas information of carbon dioxide or total volatile organic compounds, or a formaldehyde sensor that detects gas information of formaldehyde, or a bacteria sensor that detects bacteria information or fungal information, or a virus sensor that detects gas information of a virus.

[0017] The piezoelectric actuator 322 is accommodated in the square air-conducting component mounting area 3215 of the base 321. Further, the air-conducting component mounting area 3215 communicates with the air intake groove 3214. When the piezoelectric actuator 322 operates, the gas in the air intake groove 3214 is sucked into the piezoelectric actuator 322, and the gas enters the exhaust groove 3216 through the ventilation hole 3215a of the air-conducting component mounting area 3215. The drive circuit board 323 covers the second surface 3212 of the base 321. The laser component 324 is installed on and electrically connected to the drive circuit board 323. The particulate sensor 325 is also installed on and electrically connected to the drive circuit board 323. When the outer cover 326 covers the base 321, the air intake frame opening 3261a corresponds to the air intake port 3214a of the base 321, and the exhaust frame opening 3261b corresponds to the exhaust port 3216a of the base 321.

[0018] The piezoelectric actuator 322 includes a gas orifice plate 3221, a chamber housing 3222, an actuator 3223, an insulating housing 3224, and a conductive housing 3225. The gas orifice plate 3221 is made of a flexible material and has a suspension plate 3221a and a hollow hole 3221b. The suspension plate 3221a is a sheet-like structure that vibrates in bending, and its shape and dimensions correspond to the inner edge of the air-conducting component mounting area 3215. The hollow hole 3221b penetrates the center of the suspension plate 3221a so that gas can flow through. In a preferred embodiment of the present invention, the shape of the suspension plate 3221a may be any of a square, a circle, an ellipse, a triangle, and a polygon.

[0019] The above-mentioned chamber housing 3222 is stacked on the gas orifice plate 3221, and its appearance corresponds to that of the gas orifice plate 3221. The actuator 3223 is stacked on the chamber housing 3222, and defines a resonance chamber 3226 between the chamber housing 3222 and the suspension plate 3221a. The insulating housing 3224 is stacked on the actuator 3223, and its appearance is similar to that of the chamber housing 3222. The conductive housing 3225 is stacked on the insulating housing 3224, and its appearance is similar to that of the insulating housing 3224. The conductive housing 3225 has a conductive pin 3225a and a conductive electrode 3225b. The conductive pin 3225a extends outward from the outer edge of the conductive housing 3225, and the conductive electrode 3225b extends inward from the inner edge of the conductive housing 3225. Further, the actuator 3223 further includes a piezoelectric carrier plate 3223a, a resonance adjustment plate 3223b, and a piezoelectric plate 3223c. The piezoelectric carrier plate 3223a is stacked on the chamber housing 3222. The resonance adjustment plate 3223b is stacked on the piezoelectric carrier plate 3223a. The piezoelectric plate 3223c is stacked on the resonance adjustment plate 3223b. The resonance adjustment plate 3223b and the piezoelectric plate 3223c are accommodated in the insulating housing 3224. The piezoelectric plate 3223c is electrically connected to the conductive electrode 3225b of the conductive housing 3225. In a preferred embodiment of the present invention, both the piezoelectric carrier plate 3223a and the resonance adjustment plate 3223b are conductive materials. The piezoelectric carrier plate 3223a has a piezoelectric pin 3223d, and the piezoelectric pin 3223d and the conductive pin 3225a are connected to a drive circuit (not shown) on the drive circuit board 323 to receive a drive signal (which may be a drive frequency and a drive voltage). The drive signal can form a loop through the piezoelectric pin 3223d, the piezoelectric carrier plate 3223a, the resonance adjustment plate 3223b, the piezoelectric plate 3223c, the conductive electrode 3225b, the conductive housing 3225, and the conductive pin 3225a. The insulating housing 3224 blocks the conductive housing 3225 and the actuator 3223 to prevent a short-circuit phenomenon and transmit the drive signal to the piezoelectric plate 3223c. After receiving the drive signal, the piezoelectric plate 3223c deforms due to the piezoelectric effect, and further drives the piezoelectric carrier plate 3223a and the resonance adjustment plate 3223b to generate reciprocating bending vibration.

[0020] More specifically, the resonance adjustment plate 3223b is positioned between the piezoelectric plate 3223c and the piezoelectric carrier plate 3223a as a buffer material therebetween, and can adjust the vibration frequency of the piezoelectric carrier plate 3223a. Basically, the thickness of the resonance adjustment plate 3223b is larger than that of the piezoelectric carrier plate 3223a, and the vibration frequency of the actuator 3223 is adjusted by changing the thickness of the resonance adjustment plate 3223b.

[0021] Refer to FIGS. 7A, 7B, 8A, 8B and 9A. The gas orifice plate 3221, the chamber housing 3222, the actuator 3223, the insulating housing 3224, and the conductive housing 3225 are sequentially stacked and positioned within the air guiding component mounting area 3215. As a result, the piezoelectric actuator 322 is positioned within the air guiding component mounting area 3215. The piezoelectric actuator 322 defines a gap 3221c for gas flow between the suspension plate 3221a and the inner edge of the air guiding component mounting area 3215. An air flow chamber 3227 is formed between the gas orifice plate 3221 and the bottom surface of the air guiding component mounting area 3215. The air flow chamber 3227 communicates with the resonance chamber 3226 between the actuator 3223, the chamber housing 3222, and the suspension plate 3221a through the hollow hole 3221b of the gas orifice plate 3221. By making the vibration frequency of the gas in the resonance chamber 3226 the same as the vibration frequency of the suspension plate 3221a, the resonance chamber 3226 and the suspension plate 3221a produce the Helmholtz resonance effect, enhancing the gas transport efficiency. When the piezoelectric plate 3223c moves away from the bottom surface of the air guiding component mounting area 3215, the piezoelectric plate 3223c moves the suspension plate 3221a of the gas orifice plate 3221 away from the bottom surface of the air guiding component mounting area 3215, causing the volume of the air flow chamber 3227 to rapidly expand, the internal pressure to decrease and generate a negative pressure. The gas outside the piezoelectric actuator 322 is sucked in and flows in from the gap 3221c, enters the resonance chamber 3226 through the hollow hole 3221b, increasing the air pressure in the resonance chamber 3226 and generating a pressure gradient. When the piezoelectric plate 3223c moves the suspension plate 3221a of the gas orifice plate 3221 towards the bottom surface of the air guiding component mounting area 3215, the gas in the resonance chamber 3226 rapidly flows out through the hollow hole 3221b, squeezing out the gas in the air flow chamber 3227, and ejecting the confluent gas quickly and in large quantities in an ideal air state close to Bernoulli's theorem and introducing it into the ventilation hole 3215a of the air guiding component mounting area 3215.

[0022] By repeating the operations shown in FIGS. 9B and 9C, the piezoelectric plate 3223c reciprocates. According to the inertia principle, when the internal air pressure in the resonance chamber 3226 after exhaust becomes lower than the equilibrium air pressure, the gas is guided to enter the resonance chamber 3226 again. In this way, by controlling the vibration frequency of the gas in the resonance chamber 3226 to be the same as the vibration frequency of the piezoelectric plate 3223c, the Helmholtz resonance effect is generated to achieve high-speed and large-volume gas transportation. All the gas enters from the intake frame opening 3261a of the outer lid 326, passes through the intake port 3214a and enters the intake groove 3214 of the base 321, and flows to the position of the particulate sensor 325. Also, by continuously driving the piezoelectric actuator 322 to absorb the gas in the intake path, the external gas is quickly introduced and stably circulated, passing above the particulate sensor 325. At this time, the beam emitted by the laser component 324 enters the intake groove 3214 through the light transmission window 3214b, and the intake groove 3214 passes above the particulate sensor 325. When the beam of the particulate sensor 325 irradiates the suspended particulates in the gas, a scattering phenomenon and a projection spot occur. The particulate sensor 325 receives the projection spot due to scattering and performs calculations to obtain relevant information such as the particle size and concentration of the suspended particulates contained in the gas. The gas above the particulate sensor 325 is also introduced into the ventilation hole 3215a of the air guiding component mounting area 3215 by the continuous driving of the piezoelectric actuator 322 and enters the exhaust groove 3216. Finally, after the gas enters the exhaust groove 3216, since the piezoelectric actuator 322 continues to transport the gas to the exhaust groove 3216, the gas in the exhaust groove 3216 is pushed out and discharged to the outside through the exhaust port 3216a and the exhaust frame opening 3261b.

[0023] The gas detection device 3 of the present invention not only includes a particulate sensor 325 capable of detecting particulate matter information regarding suspended particulate matter (such as PM1, PM2.5, PM10, etc.) in the gas, but can further detect the characteristics of the introduced gas such as formaldehyde, ammonia, carbon monoxide, carbon dioxide, oxygen gas, ozone, etc. Therefore, the gas detection device 3 of the present invention further includes a gas sensor 327. The gas sensor 327 is positioned and installed on the drive circuit board 323 and electrically connected, and is housed in the exhaust groove 3216 to detect the gas derived from the exhaust path. The gas sensor 327 includes a volatile organic compound sensor that detects gas information of carbon dioxide or total volatile organic compounds. The gas sensor includes a formaldehyde sensor that detects gas information of formaldehyde. The gas sensor 327 includes a bacteria sensor that detects bacteria information or fungus information. The gas sensor 327 includes a virus sensor that detects gas information of a virus.

[0024] The above central control and monitoring device B is either a central control box or a portable mobile device. It receives outdoor air pollution data and indoor air pollution data through wireless communication, performs intelligent calculation and comparison, and issues control commands intelligently and selectively. The central control and monitoring device B is a portable mobile device, and in combination with a purification and prevention system application (APP) that brings indoor air pollution close to zero, it can execute control commands and display indoor / outdoor air pollution data. The wireless communication is any one of a Wi-Fi module, a Bluetooth (registered trademark) module, a radio frequency identification module, and a near-field communication module. In this embodiment, the central control and monitoring device B can be connected to the cloud device E via a network. The cloud device E receives the outdoor air pollution data and indoor air pollution data collected by the central control and monitoring device B, performs intelligent calculation and comparison of the outdoor air pollution data and the indoor air pollution data, identifies the location / area of the air pollution in the indoor space, and issues control commands intelligently and selectively.

[0025] Continue to refer to FIGS. 1A and 1B. Each of the above air exchange and filtration devices C includes at least one air guiding device 1 and at least one filtration component 2. The air guiding device 1 has the function of transporting gas in both the exhaust and supply directions. In this embodiment, the air flow path in the direction indicated by the arrow is used for explanation. The air guiding device 1 may be installed in front of the filtration component 2, behind the filtration component 2, or both in front of and behind the filtration component 2 (as shown in FIG. 3A), and the air guiding device 1 can be adjusted according to actual requirements and designs. Also, each of the above air exchange and filtration devices C is combined with a smart switch D. The smart switch D is a unit that realizes smart switching control of a circuit by combining a control panel and electronic components for programming, that is, it controls the switching of devices through wireless communication connection. The smart switch D receives a control command to start the operation of the air guiding device 1. The smart switch D receives the control command through wireless communication, that is, the smart switch D receives the control command transmitted from the central control and monitoring device B through wireless communication. The wireless communication is any one of a Wi-Fi module, a Bluetooth (registered trademark) module, a radio frequency identification module, and a near field communication module.

[0026] Whether the wireless communication connection signal of the above smart switch D is normal can be detected and judged by the central control and monitoring device B. When the wireless communication connection signal of the connected air exchange and filtration device C is not normal, a warning can be displayed or notified. At this time, in order to realize a debugging mechanism for preventing communication connection failures in advance, the user needs to be notified that it is necessary to start the manual operation of the air exchange and filtration device C, so that the entire purification and prevention system for approaching indoor air pollution to zero will not become ineffective. By the user manually operating the air exchange and filtration device C in real time, until the indoor air pollution data detected by a plurality of gas detection devices A reaches the safety detection value, the filtration component 2 quickly filters the air pollution, so as to quickly remove the air pollution and approach zero, and reach the state where the air in the indoor space is clean and breathable.

[0027] Also, in the present embodiment shown in FIG. 1B, instead of the air exchange and filtration device C, a gas detection device A is provided inside each of the air exchange and filtration devices C. The gas detection device A controls the driving operation of the air exchange and filtration device C, receives the control command, controls the opening and closing mechanism of the air guiding device 1, and controls the air volume adjustment of the air guiding device 1. The gas detection device A provided inside the air exchange and filtration device C can control the operating mechanism of the air guiding device 1 according to the detected indoor air pollution data exceeding the safety detection value, and controls the air guiding device 1 to adjust an appropriate air volume requirement according to the outdoor air pollution data and the indoor air pollution data, so that the air exchange and filtration device can more intelligently control the starting mechanism of the air guiding device 1. That is, when the gas detection device A provided inside the air exchange and filtration device C detects that the indoor air pollution data exceeds the safety detection value, it can actively control the operating mechanism of the air guiding device 1 of the air exchange and filtration device C, and according to the detected indoor air pollution data, control the air guiding device 1 to adjust an appropriate air volume, and quickly filter and remove air pollution by the nearby filtration component 2, and a more intelligent, timely and energy-saving control mechanism for filtration and removal by the air exchange and filtration device C can be realized. The gas detection device A has the same configuration as the above-described gas detection device 3, and the control circuit board 31 of the gas detection device A can control the opening and closing and air volume adjustment mechanism of the air guiding device 1, which will not be repeated here.

[0028] As can be understood from the above description, as a specific operation of the purification and prevention system for bringing indoor air pollution close to zero of the present invention, by arranging a plurality of gas detection devices A in the indoor space, at least one outdoor gas detector A0 and at least one indoor gas detector A1 perform detection, output outdoor air pollution data and indoor air pollution data, and the central control monitoring device B receives the outdoor air pollution data and the indoor air pollution data through wireless communication, connects to the cloud device E, and the cloud device E performs intelligent calculation and comparison. When the indoor air pollution data received by the central control monitoring device B is greater than the outdoor air pollution data, the central control monitoring device B intelligently issues a control command, and the central control monitoring device B receives the control command and immediately controls the driving operation of the air guiding device 1 of the air exchange and filtration device C to quickly exchange the air pollution in the indoor space and discharge it outdoors, and quickly circulates the air pollution through the filtration component 2 to filter and remove it until the safety detection value is reached. In an embodiment of the present invention, the air exchange and filtration device C may be a heating, ventilation, and air conditioning system (HVAC), the filtration component 2 is a filter with a minimum filtration efficiency value (MERV) of 8 or more, and the air pollution in the indoor space is quickly exchanged and discharged outdoors. In another embodiment, the air exchange and filtration device C may be a ventilation system C1, the filtration component 2 is a high-efficiency particulate air (HEPA) filter, and the air pollution in the indoor space is quickly exchanged and discharged outdoors.

[0029] In addition, the cloud device E performs intelligent calculation and comparison on indoor air pollution data. The intelligent calculation implements the comparison between artificial intelligence (AI) calculation and big data, and can identify the location and area of the air pollution in the indoor space by using the highest one among the indoor air pollution data. Or after comparing the indoor air pollution data detected by at least three or more indoor gas detectors, perform intelligent calculation to identify the location and area of the air pollution in the indoor space using at least three detection points. At this time, after the cloud device E identifies the location and area of the air pollution in the indoor space, it issues a control command intelligently and selectively, and sends it to the central control and monitoring device B. The central control and monitoring device B sends it to a plurality of the air exchange and filtration devices C to activate the control mechanism. In this control mechanism, after the air exchange and filtration device C within the location and area of the air pollution receives the control command and preferentially starts operating, it forms a path for purified air pollution. That is, after the air guiding device 1 of the air exchange and filtration device C within the location and area of the air pollution forms an activation operation mechanism, the control command is sent to other air exchange and filtration devices C outside the location and area of the air pollution to form a second activation operation. That is, by subsequently forming a second activation operation mechanism for the air guiding device 1 of other air exchange and filtration devices C outside the location and area of the air pollution, gas convection is generated and directed towards the air pollution to accelerate the convective circulation of the air pollution within the location and area of the air pollution. At this time, the air exchange and filtration device C within the location and area of the air pollution can not only instantaneously filter and remove it, but also diffuse, move, and be directed towards the air pollution outside the location and area of the air pollution, and the filtration and removal can be accelerated by other air exchange and filtration devices C outside the location and area of the air pollution. Therefore, the safety detection value of the air pollution in the indoor space is detected, and the air pollution is detected and removed so as to instantaneously approach or reach zero, and the air pollution is purified to a safe breathing air state. In the specific embodiment of the present invention, as shown in FIGS. 1A and 1B, the plurality of air exchange and filtration devices C may be any one or a combination of a ventilation system C1, an air purifier C2, a heating, ventilation, and air conditioning device C3, an exhaust fan C4, a blower C5, or a range hood C6, but is not limited thereto.That is, the type and number of the air exchange and filtration device C are not limited to one. That is, one or more air exchange and filtration devices C may be provided, and the type and number of the air exchange and filtration device C can be adjusted based on the size of the indoor space and the requirements for the actual air filtration quality.

[0030] In addition, in the embodiment of the present invention, the filtering component 2 of the air exchange and filtering device C removes the air pollution by a physical method of blocking and adsorbing with a filter. Or, by applying the decomposition layer 21 to the filtering component 2, the air pollution is chemically removed. Or, the filtering component 2 chemically removes the air pollution in combination with light irradiation 22. Or, the filtering component 2 chemically removes the air pollution in combination with the decomposition unit 23, but is not limited thereto. The filter is a high-efficiency filter 2a, which achieves the effect of filtering and purifying the introduced air pollution by adsorbing chemical smog, bacteria, dust particles and pollen contained in the air pollution. The decomposition layer 21 is activated carbon 21a, which removes organic and inorganic substances in air pollution and removes colored and odoriferous substances. The decomposition layer 21 is a chlorine dioxide cleaning factor 21b, which suppresses viruses, bacteria, fungi, influenza A virus, influenza B virus, enterovirus, norovirus in air pollution, and the suppression rate reaches 99% or more, contributing to reducing the cross-infection of viruses. The decomposition layer 21 is a herb protection layer 21c containing ginkgo and Rhus chinensis, which effectively resists allergies and destroys the surface protein of influenza virus (for example, H1N1). The decomposition layer 21 is silver ions 21d, which suppress viruses, bacteria and fungi in the introduced air pollution. The decomposition layer 21 is zeolite 21e, which removes ammonia nitrogen, heavy metals, organic pollutants, Escherichia coli, phenol, chloroform, and anionic surfactants. The light irradiation 22 is a photocatalytic unit including a photocatalyst 22a and an ultraviolet lamp 22b. When the photocatalyst 22a is irradiated by the ultraviolet lamp 22b, it converts light energy into electrical energy, decomposes harmful substances in air pollution to disinfect and sterilize, and thus can achieve the effect of filtering and purifying.The light irradiation 22 is a photo-plasma unit including carbon nanotubes 22c. By irradiating the introduced air pollution with the carbon nanotubes 22c, oxygen molecules and water molecules in the air pollution are decomposed into photo-plasma with high oxidizing properties to form an ion airflow having destroyed organic molecules, and gas molecules such as volatile formaldehyde, toluene, and volatile organic compounds (VOCs) contained in the air pollution are decomposed into water and carbon dioxide to achieve the effect of filtration and purification.

[0031] As described above, the present invention provides a purification and prevention system for bringing indoor air pollution close to zero. By installing a plurality of gas detection devices, the nature, concentration, and location of the air pollution are identified. The central control and monitoring device receives the outdoor air pollution data and the indoor air pollution data through wireless communication and performs intelligent calculation and comparison. Further, by connecting the central control and monitoring device to a cloud device, after performing various mathematical operations and artificial intelligence operations to identify the location of the air pollution, a control command is issued intelligently and selectively, and the air exchange and filtration device in the area closest to the location of the air pollution is activated to generate an air current, quickly guiding the air pollution to at least one air exchange and filtration device for filtration, and filtering and removing the air pollution by the filtration component until the indoor air pollution data detected by the plurality of gas detection devices reaches a safety detection value. Thereby, the air pollution can be quickly and instantaneously removed so as to approach zero or reach zero, and the air in the indoor space can be made clean and breathable, and the industrial applicability is very high.
