Description

[Technical field]

[0001] The present invention relates to an indoor air purifying system, and particularly to an indoor air purifying system that is applied to an indoor space and whose gas condition reaches a clean room class according to a cleanliness specification based on the number of particles passing through. [Background technology]

[0002] Suspended particles refer to solid particles or liquid droplets contained in gas. Because the particle size is very small, they can easily enter human lungs through nasal hairs in the nasal cavity, causing lung inflammation, asthma, and cardiovascular disease. In addition, if other pollutants adhere to the suspended particles, they may harm the respiratory system and worsen the damage. In recent years, the problem of air pollution has become increasingly serious, and the concentration data of suspended particles (e.g., fine particles such as PM2.5) is often too high, so the concentration monitoring of gas-suspended particulate matter has gradually attracted attention. However, gas changes due to wind direction and unstable wind volume, and most of the current gas quality monitoring stations that detect suspended particulate matter are fixed-point observations, so it is not possible to check the concentration of suspended particulate matter in the surrounding area.

[0003] Furthermore, modern humans are subject to carbon monoxide, carbon dioxide, volatile organic compounds (VOCs), and PM 2.5 Exposure to gases such as nitrogen monoxide and sulfur, as well as fine particles contained in gases, in the environment can affect human health and, in severe cases, even endanger life, so people are increasingly paying attention to the quality of the gas around them. Therefore, the quality of the ambient gas has attracted the attention of many countries, and how to avoid areas with poor gas quality and how to detect the gas quality to avoid them has become an important issue.

[0004] To check the quality of gas, a gas sensor can be used to detect the surrounding gas. If the gas is detected and the detection information is provided in real time, it can warn people in the vicinity so that they can avoid the situation immediately. In order to avoid the impact and injury of the gas hazards in the environment to the human body, using a gas sensor to detect the surrounding environment is a very good application.

[0005] In addition, it is not easy to grasp indoor air quality. In addition to outdoor air quality, indoor air conditioning conditions and pollution sources are the main factors that affect indoor air quality. It is possible to intelligently and quickly detect indoor air pollution sources in each area indoors, effectively remove indoor air pollution to form a safe breathable state, and monitor indoor air quality in real time anytime and anywhere. Of course, if the concentration of suspended particles in the air can be controlled according to the "clean room" standard in the indoor field, and efforts are made to avoid the introduction, generation and retention of fine particles, and the temperature and humidity can be controlled within the required range, that is, if the indoor field can distinguish classes according to the number of suspended particles in the air, it will reach the clean room requirements of a safe breathable indoor feel. Therefore, the main task of the present invention is how to detect indoor air quality and how to solve the problem of air pollution so that the indoor field can reach the requirements of the clean room and avoid the impact and injury of gaseous harmful substances in the environment on the human body. Summary of the Invention [Problem to be solved by the invention]

[0006] The main object of the present invention is to provide an indoor air purification system, comprising a plurality of gas sensors, at least one purification device, and a cloud computing service device, the gas sensors being arranged in outdoor and indoor fields, the purification device being configured to monitor outdoor and indoor air pollution information in real time, receive air pollution information through Internet of Things (IoT) communication through the cloud computing service device, store air pollution data in a big data database, intelligently calculate and compare to determine the location of air pollution, and intelligently select a control command and transmit it to the fan of the purification device through Internet of Things communication to start it and control the air volume, thereby generating a circulating directional airflow in the indoor field, guiding the air pollution in the indoor field to be quickly filtered and purified to a class close to zero through the filtering member, and sterilized and purified through the sterilization assembly, improving the purification efficiency of the indoor field, and reducing the environmental noise of the indoor field. In this way, the indoor air purification system forms a detection and purification prevention effect of identifying the location of air pollution, guiding air pollution, and purifying air pollution to a class close to zero. In addition, the filter material of the purifier is a high-efficiency particulate air filter (HEPA) class filter for filtering air pollution, and the fan of the purifier has a specific clean air delivery rate (CADR) to generate a circulating directional airflow, so that the gas condition of the indoor field reaches the clean room class requirements according to the cleanliness specification based on the number of passing particles, and the impact and injury to the human body caused by gaseous harmful substances in the environment is avoided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The following detailed description will be given of the embodiments embodying the features and advantages of the present invention. It should be noted that the present invention can be modified in various ways without departing from the scope of the present invention. It should be understood that the present specification and drawings are for illustrative purposes only and not for limiting the present invention.

[0010] As shown in Figs. 1, 2A and 2B, the indoor air purification system according to the present invention includes a plurality of gas sensors 1, at least one purification device 2 and a cloud computing service device 4. The plurality of gas sensors 1 may be arranged in an outdoor field A and an indoor field B to detect air pollution. In the embodiment of Fig. 1 of the present invention, one gas sensor 1 is arranged in the outdoor field A to detect outdoor air pollution and output outdoor air pollution information via Internet of Things (IoT) communication, and the plurality of gas sensors 1 are arranged in the indoor field B to detect indoor air pollution and output indoor air pollution information via Internet of Things (IoT) communication. The purification device 2 includes a fan 21, a filtering member 22 and a sterilization assembly 23. The fan 21 is activated and operated via Internet of Things communication, and the fan 21 is controlled to guide the air pollution to pass through the filtering member 22 and pass through the sterilization assembly 23 to be sterilized and purified. The fan 21 has a specific clean air delivery rate (CADR) for generating a circulating directional airflow, and the filter member 22 is a high efficiency particulate air filter (HEPA). The cloud computing service device 4 receives indoor and outdoor air pollution information through Internet of Things (IoT) communication, stores it in a big data database of air pollution data, intelligently calculates and compares the air pollution data based on the big data database, intelligently selects and sends a control command, and transmits it to the fan 21 of the purifier 2 through Internet of Things communication to operate it, thereby generating a circulating directional airflow (the circulating airflow path is indicated by a broken line in FIG. 1) in the indoor field B. Thus, the air pollution in the indoor field B is quickly guided to pass through the filter member 22 multiple times to be filtered and purified, and then passes through the sterilization assembly 23 to be sterilized, so that the gas state in the indoor field achieves the cleanliness specification according to the particle number that forms a clean room class.

[0011] A gas detection module is provided inside the gas sensor 1. As shown in Figures 3A and 3B, the gas sensor 1 may include an external power supply terminal, and may be started up by directly inserting the external power supply terminal into a power supply port in the indoor field B to detect air pollution. Alternatively, as shown in Figure 3C, the gas sensor 1 may not include a gas detection module of an external power supply terminal, but may be directly configured on an apparatus (purifying apparatus 2), and may be connected to a power source and started up to detect air pollution.

[0012] The air pollution includes 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. The computing includes artificial intelligence (AI) computing and edge computing. The Internet of Things (IoT) refers to a collective network that connects various devices and technology that supports communication between the devices and the cloud and between the devices.

[0013] The structure of the gas detection module of the gas sensor 1 according to the present invention will be described in detail below. As shown in Figs. 3A to 11, 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 and integrally formed on the control circuit board 11, and are electrically connected. The microprocessor 13 and the communication device 14 are provided on the control circuit board 11, and the microprocessor 13 controls the drive signal of the gas detection main body 12 to start the detection operation. In this way, the gas detection main body 12 detects air pollution and outputs detection information, which is received and processed by the microprocessor 13, provided to the communication device 14, and externally transmitted to the cloud computing service device 4 via Internet of Things (IoT) communication. In an Internet of Things (IoT) embodiment of the present invention, the gas sensor 1 communicates with the cloud computing service device 4 via wireless communication, which may be a Wi-Fi module, a Bluetooth module, a radio frequency identification module, or a near field communication module.

[0014] As shown in FIGS. 4A to 9A, the gas detection main body 12 includes a base 121, an actuator 122, a drive circuit board 123, a laser assembly 124, a particulate sensor 125, and an outer lid 126. The base 121 includes a first surface 1211, a second surface 1212, a laser installation area 1213, an air inlet groove 1214, a gas guide assembly arrangement area 1215, and an exhaust groove 1216. The first surface 1211 and the second surface 1212 are two surfaces provided opposite to each other. The laser installation area 1213 is formed by hollowing out from the first surface 1211 toward the second surface 1212. The outer lid 126 covers the base 121 and has a side plate 1261 having an air inlet opening 1261a and an exhaust opening 1261b. The air inlet groove 1214 is recessed from the second surface 1212 and is adjacent to the laser installation area 1213. The air inlet groove 1214 is connected to the outside of the base 121 and is provided with an air inlet vent 1214a corresponding to the air inlet opening 1261a of the outer lid 126. A light-transmitting window 1214b is formed through both side walls of the air inlet groove 1214 and connected to the laser installation area 1213. Therefore, the first surface 1211 of the base 121 is covered by the outer lid 126 and the second surface 1212 is covered by the drive circuit board 123, and thus an air inlet path is defined by the air inlet groove 1214.

[0015] The gas guide assembly arrangement area 1215 is recessed from the second surface 1212, communicates with the air inlet groove 1214, and has a vent hole 1215a penetrating the bottom surface. The gas guide assembly arrangement area 1215 has positioning protrusions 1215b at each of its four corners. The exhaust groove 1216 is provided with an exhaust vent 1216a corresponding to the exhaust opening 1261b of the outer cover 126. The exhaust groove 1216 includes a first section 1216b recessed in a vertical projection area of ​​the first surface 1211 relative to the gas guide assembly arrangement area 1215, and a second section 1216c hollowed out from the first surface 1211 to the second surface 1212 in a region extending from the vertical projection area of ​​the gas guide assembly arrangement area 1215. The first section 1216b and the second section 1216c are connected to form a step, and the first section 1216b of the exhaust groove 1216 communicates with the ventilation hole 1215a of the gas guide assembly arrangement area 1215, and the second section 1216c of the exhaust groove 1216 communicates with the exhaust vent 1216a. Therefore, when the first surface 1211 of the base 121 is covered with the outer lid 126 and the second surface 1212 is covered with the driving circuit board 123, an exhaust path is defined by the exhaust groove 1216 and the driving circuit board 123.

[0016] The laser assembly 124 and the particulate sensor 125 are both mounted on the driving circuit board 123 and located in the base 121. In order to more clearly explain the positions of the laser assembly 124 and the particulate sensor 125 and the base 121, the driving circuit board 123 is intentionally omitted. The laser assembly 124 is accommodated in the laser installation area 1213 of the base 121, and the particulate sensor 125 is accommodated in the air inlet groove 1214 of the base 121 and aligned with the laser assembly 124. The laser assembly 124 corresponds to the light-transmitting window 1214b, through which the laser light emitted from the laser assembly 1244 passes and is irradiated to the laser light air inlet groove 1214. The light beam path emitted from the laser assembly 124 passes through the light-transmitting window 1214b and is perpendicular to the air inlet groove 1214. The light beam emitted from the laser assembly 124 passes through the light-transmitting window 1214b and enters the air inlet groove 1214, where it is irradiated to particles suspended in the gas within the air inlet groove 1214, and when the light beam comes into contact with the gas, it is scattered to generate a projection spot. The particle sensor 125 is positioned in the perpendicular direction, and receives and calculates the scattered projection spot to obtain detection data of particles suspended in the air.

[0017] The actuator 122 may be a fan or a piezoelectric pump, but in this embodiment, the actuator 122 is described as a piezoelectric pump as an example, but is not limited thereto. The actuator 122 is accommodated in a square gas guide assembly arrangement area 1215 of the base 121. The gas guide assembly arrangement area 1215 and the inlet groove 1214 are in communication with each other. When the actuator 122 is operated, the gas in the inlet groove 1214 is sucked into the actuator 122, and the gas passes through the vent hole 1215a of the gas guide assembly arrangement area 1215 and enters the exhaust groove 1216. The driving circuit board 123 covers the second surface 1212 of the base 121. The laser assembly 124 is provided on the driving circuit board 123 and is electrically connected thereto. The particulate sensor 125 is also provided on the driving circuit board 123 and is electrically connected thereto. When the outer lid 126 covers the base 121 , the air inlet opening 1261 a corresponds to the air inlet vent 1214 a of the base 121 , and the air exhaust opening 1261 b corresponds to the air exhaust vent 1216 a of the base 121 .

[0018] The actuator 122 includes a blower sheet 1221, a cavity frame 1222, an actuator 1223, an insulating frame 1224, and a conductive frame 1225. The blower sheet 1221 is made of a flexible material and has a floating sheet 1221a and a hollow hole 1221b. The floating sheet 1221a is a sheet-like structure capable of bending and vibrating, and its shape and dimensions correspond to the inner edge of the gas guide assembly arrangement area 1215, and the hollow hole 1221b penetrates the center part of the floating sheet 1221a to allow gas to flow. In a preferred embodiment of the present invention, the shape of the floating sheet 1221a may be any one of a rectangle, a circle, an ellipse, a triangle, and a polygon.

[0019] The cavity frame 1222 is laminated on the blowhole sheet 1221, and its shape corresponds to the blowhole sheet 1221. The actuator 1223 is laminated on the cavity frame 1222, and a resonant chamber 1226 is formed between the blowhole sheet 1221 and the floating sheet 1221a. The insulating frame 1224 is laminated on the actuator 1223, and its shape is similar to that of the cavity frame 1222. The conductive frame 1225 is laminated on the insulating frame 1224, and its shape is similar to that of the insulating frame 1224. The conductive frame 1225 has 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. The actuator 1223 further includes a piezoelectric mounting plate 1223a, an adjusted resonator plate 1223b, and a piezoelectric plate 1223c. The piezoelectric mounting plate 1223a is stacked on the cavity frame 1222. The adjusted resonator plate 1223b is stacked on the piezoelectric mounting plate 1223a. The piezoelectric plate 1223c is stacked on the adjusted resonator plate 1223b. The adjusted resonator plate 1223 and the piezoelectric plate 1223c are accommodated in an insulating frame 1224. The piezoelectric plate 1223c is electrically connected to the piezoelectric plate 1223c by a conductive electrode 1225b of a conductive frame 1225. In a preferred embodiment of the present invention, the piezoelectric mounting plate 1223a and the adjusted resonator plate 1223b are both made of conductive materials. The piezoelectric mounting plate 1223a has 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 (which may be a driving frequency and a driving voltage), whereby the piezoelectric pin 1223d, the piezoelectric mounting plate 1223a, the adjusted resonant plate 1223b, the piezoelectric plate 1223c, the conductive electrode 1225b, the conductive frame 1225 and the conductive pin 1225a form a circuit, and the insulating frame 1224 isolates the conductive frame 1225 and the actuator 1223 to avoid a short circuit, so that the driving signal can be transmitted to the piezoelectric plate 1223c. After receiving the driving signal, the piezoelectric plate 1223c is deformed by the piezoelectric effect, and further drives the piezoelectric mounting plate 1223a and the adjusted resonant plate 1223b to flexurally vibrate back and forth.

[0020] Furthermore, the adjusted resonance plate 1223b is located between the piezoelectric plate 1223c and the piezoelectric mounting plate 1223a, and serves as a buffer between the two, enabling adjustment of the vibration frequency of the piezoelectric mounting plate 1223a. Basically, the thickness of the adjusted resonance plate 1223b is greater than that of the piezoelectric mounting plate 1223a, and the vibration frequency of the actuator 1223 is adjusted by adjusting the thickness of the adjusted resonance plate 1223b.

[0021] As shown in Figures 7A, 7B, 8A, 8B and 9A, the blower sheet 1221, the cavity frame 1222, the actuator 1223, the insulating frame 1224 and the conductive frame 1225 are stacked in order and positioned in the gas guide assembly arrangement area 1215, so that the actuator 122 is positioned in the gas guide assembly arrangement area 1215. The actuator 122 has a gap 1221c for gas flow between the floating sheet 1221a and the inner edge of the gas guide assembly arrangement area 1215. An airflow chamber 1227 is formed between the blower sheet 1221 and the bottom surface of the gas guide assembly arrangement area 1215. The airflow chamber 1227 is connected to the resonance chamber 1226 between the actuator 1223, the cavity frame 1222, and the floating sheet 1221a of the blower hole sheet 1221 via the hollow holes 1221b in the blower hole sheet 1221. By making the vibration frequency of the gas in the resonance chamber 1226 the same as the vibration frequency of the floating sheet 1221a, the resonance chamber 1226 and the floating sheet 1221a generate a Helmholtz resonance effect, improving the gas transport efficiency. When the piezoelectric plate 1223c moves away from the bottom surface of the gas guide assembly placement area 1215, the piezoelectric plate 1223c moves the floating sheet 1221a of the blower sheet 1221 away from the bottom surface of the gas guide assembly placement area 1215, causing the volume of the airflow chamber 1227 to expand suddenly, the internal pressure to decrease and generate negative pressure, and gas outside the actuator 122 flows in through the gap 1221c and enters the resonating chamber 1226 via the hollow hole 1221b, increasing the air pressure in the resonating chamber 1226 and generating a pressure gradient. When the piezoelectric plate 1223c moves the floating sheet 1221a of the blower sheet 1221 to the bottom surface of the gas guide assembly placement area 1215, the gas in the resonance chamber 1226 quickly flows out through the hollow hole 1221b, pressing against the gas in the air flow chamber 1227, causing the merged gas to be ejected quickly and in large quantities under ideal air conditions close to Bernoulli's theorem, and introduced into the air vent 1215a of the input gas guide assembly placement area 1215.

[0022] 9B and 9C, the piezoelectric plate 1223c vibrates back and forth, and according to the principle of inertia, when the internal air pressure of the resonance chamber 1226 after exhaust becomes lower than the equilibrium air pressure, the gas is guided to enter the resonance chamber 1226 again. In this way, the vibration frequency of the gas in the resonance chamber 1226 is controlled to be the same as the vibration frequency of the piezoelectric plate 1223c, thereby generating the Helmholtz resonance effect and realizing high-speed and large-volume transportation of gas. All the gas enters through the intake opening 1261a of the outer cover 126, passes through the intake vent 1214a, enters the intake groove 1214 of the base 121, and flows to the position of the particle sensor 125. In addition, the gas in the intake path is absorbed by the continuous drive of the actuator 122, so that the outside gas is quickly introduced and stably flows, passing above the particle sensor 125. At this time, the light beam emitted from the laser assembly 124 passes through the light-transmitting window 1214b, enters the air inlet groove 1214, and passes above the particle sensor 125. When the light beam from the laser assembly 124 is irradiated on the suspended particles in the gas, a scattering phenomenon and a projection spot are generated, so that the particle sensor 125 receives the projection spot caused by scattering and performs calculations to obtain relevant information such as the particle diameter and concentration of the suspended particles contained in the gas, and the gas above the particle sensor 125 is also introduced into the vent hole 1215a of the gas guide assembly arrangement area 1215 by the continuous driving of the actuator 122, and enters the exhaust groove 1216. Finally, when the gas enters the exhaust groove 1216, the actuator 122 continues to transport the gas to the exhaust groove 1216, so that the gas in the exhaust groove 1216 is pushed out and exhausted to the outside through the exhaust vent 1216a and the exhaust opening 1261b.

[0023] The gas sensor 1 of the present invention can detect not only suspended particles in the gas, but also the characteristics of the introduced gas, such as formaldehyde, ammonia, carbon monoxide, carbon dioxide, oxygen gas, ozone, etc. Therefore, the gas sensor 1 of the present invention further includes a gas sensor 127, which is positioned and provided, electrically connected to the driving circuit board 123, and accommodated in the exhaust groove 1216 to detect the characteristics of the introduced gas. The gas sensor 127a may include a volatile organic sensor that detects gas information of carbon dioxide or total volatile organics. The gas sensor 127 may include a formaldehyde sensor that detects gas information of formaldehyde. The gas sensor 127 may include a bacteria sensor that detects bacteria information or fungus information. The gas sensor 127 may include a virus sensor that detects virus gas information. The gas sensor 127 may include a temperature and humidity sensor that detects temperature and humidity information of the gas.

[0024] As shown in FIG. 1, FIG. 2A and FIG. 2B, the purifying device 2 includes a fan 21, a filter member 22 and a sterilizing assembly 23. The fan 21 is controlled to guide air pollution through the filter member 22 to be filtered, and guide air pollution through the sterilizing assembly 23 to be sterilized and cleaned. The filter member 22 is a high-efficiency particulate air filter (HEPA) that adsorbs chemical smoke, bacteria, dust particles and pollen contained in the air pollution, and achieves the effect of filtering and purifying the introduced air pollution. As shown in FIG. 2A, the airflow path of the fan 21 is in the direction indicated by the arrow, and the fan 21 may be provided in front of the filter member 22 or behind the filter member 22. The sterilizing assembly 23 may be configured to sterilize by a chemical method by coating the filter member 22 with a decomposition layer. The decomposition layer may be activated carbon 231 that removes organic and inorganic substances in the air pollution and removes coloring substances and odorous substances. The decomposition layer may be a chlorine dioxide cleaning agent 232 that inhibits viruses, bacteria, fungi, influenza A virus, influenza B virus, enteric virus, and norovirus in air pollution, with the inhibition rate reaching 99% or more, contributing to reducing cross-infection of viruses. The decomposition layer may be a herbaceous protective layer 233 including ginkgo and Japanese Rhus chinensis that effectively resists allergies and destroys the surface protein of influenza viruses (e.g., H1N1). The decomposition layer may be silver ions 234 that inhibit viruses, bacteria, and fungi in the introduced air pollution. The decomposition layer may be zeolite 235 that removes ammonia nitrogen, heavy metals, organic pollutants, E. coli, phenol, chloroform, and anionic surfactants.

[0025] As shown in FIG. 1 and FIG. 11, the gas sensor 1 may be directly installed in the purifier 2. The gas detection module of the gas sensor 1 is connected to the power supply and control driving circuit of the purifier 2, and the communicator 14 of the gas detection module and the cloud computing service device 4 communicate with each other through the Internet of Things (IoT). At this time, when the cloud computing service device 4 sends a control command, the fan 21 of the purifier 2 can be controlled and operated. The operation is performed by intelligently calculating and comparing the air pollution information detected in the indoor field B based on the big data database of the air pollution data of the cloud computing service device 4, thereby controlling the start-up time period and the air volume of the fan 21 of the purifier 2, improving the purification efficiency of the indoor field B, reducing the environmental noise of the indoor field B, generating a circulating directional airflow in the indoor field B, and guiding the air pollution in the indoor field B to quickly pass through the filter member 22 multiple times for filtering and cleaning, and to pass through the sterilization assembly 23 for sterilization and cleaning. In a specific embodiment, a plurality of gas sensors 1 and a plurality of purifying devices 2 are arranged in the indoor field B, and the indoor air pollution information detected by at least two or more gas sensors 1 is transmitted to the cloud computing service device 4 through the Internet of Things communication, and the location of the air pollution in the indoor field B is identified by intelligently calculating and judging, and a control command is intelligently selected and transmitted to the plurality of purifying devices 2, so that the fan 21 of the purifying device 2 closest to the air pollution location is controlled and operated to generate a directional airflow. Then, the fan 21 of the other purifying devices 2 is controlled and operated to generate a directional airflow in the indoor field B, and the air pollution in the indoor field B is guided to pass through the filtering member 22 multiple times for filtering and purifying, and is guided to pass through the sterilizing assembly 23 for sterilization and purifying, so that the gas state in the indoor field B reaches the clean room class according to the cleanliness specification based on the number of particles passing through.

When the gas exchange device 3 is started, the gas may be introduced and discharged along the path of the arrow as shown in the figure to perform ventilation between the indoor field B and the outdoor field A.

In other words, the outdoor air pollution information of the outdoor field A and the indoor air pollution information of the indoor field B are intelligently compared and calculated via the cloud computing service device 4. When the indoor air pollution information is higher than the outdoor air pollution information, a control command is sent to the gas exchange device 3 via Internet of Things (IoT) communication to start and operate it, thereby introducing the gas in the outdoor field A into the indoor field B to perform ventilation. As a result, the indoor field B maintains a positive pressure ventilation state, so that the air pollution in the indoor field B does not remain indoors and is constantly ventilated, and the multiple purifying devices 2 generate circulating directional airflows to guide the air pollution in the indoor field B to quickly pass through the filtering member 22 multiple times and be filtered and purified. When the indoor air pollution information is lower than the outdoor air pollution information, the cloud computing service device 4 sends a control command to the gas exchange device 3 via Internet of Things (IoT) communication to control the opening and closing operation, so that the gas state of the indoor field B generates a circulating directional airflow through multiple purification devices 2, and guides the air pollution of the indoor field B to pass through the filtering member 22 multiple times to be filtered and purified, so that the air pollution of the indoor field B quickly becomes a class close to zero, and at the same time, sterilizes and purifies through the sterilization assembly 23, so that the gas state of the indoor field B reaches a clean room class according to the cleanliness specification based on the number of particles passing through. Note that the gas exchange device 3 may include a fresh air fan.

[0027] As shown in FIG. 12, the cloud computing service device 4 includes a wireless network cloud computing service module 41, a cloud control service unit 42, a device management unit 43 and an application unit 44. The wireless network cloud computing service module 41 receives outdoor air pollution information of the outdoor field A, indoor air pollution information of the indoor field B, and communication information of the purifying device 2 and the gas exchange device 3, and issues a first control command and a second control command. The wireless network cloud computing service module 41 receives outdoor air pollution information of the outdoor field A and indoor air pollution information of the indoor field B, transmits them to the cloud control service unit 42 to form a big data database of air pollution data, performs intelligent calculations, and compares them through the air pollution data database to determine the location of air pollution, and sends out a control command to be transmitted to the wireless network cloud computing service module 41. In addition, the control command is transmitted to the fan 21 of the gas exchange device 3 and the purifying device 2 through the wireless network cloud computing service module 41 to control the start-up operation. The device management unit 43 receives communication information of the purification device 2 and the gas exchange device 3 via the wireless network cloud computing service module 41, performs user login and device linking management, and provides device management information to the application unit 44 to control and manage the system. The application unit 44 also displays and notifies air pollution information obtained from the cloud control service unit 42, allowing the user to check the real-time status of air pollution purification via a mobile phone or communication device, and the user controls the operation of the indoor air purification system via the application unit 44 of the mobile phone or communication device.

[0028] As can be seen from the above description, by disposing a plurality of gas sensors 1 and at least one purifying device 2 in the outdoor field A and the indoor field B, the gas sensor 1 can constantly monitor and judge the indoor and outdoor air pollution information. In addition, the air pollution information is received through the cloud computing service device 4, stored in the big data database of air pollution data, and intelligently calculated to determine the location of air pollution, and intelligently transmits a control command to the gas exchange device 3 through the Internet of Things communication to start and operate, so that the gas in the outdoor field A is introduced into the indoor field B to form ventilation, and intelligently transmits a control command to the fan 21 of the purifying device 2 through the Internet of Things communication to start and operate, so that a circulating directional airflow is generated in the indoor field B, so that the air pollution in the indoor field B is quickly filtered and purified to a class close to zero by passing through the filtering member 22 multiple times, and is guided to pass through the sterilization assembly 23 for sterilization and purification, so that the gas state in the indoor field B forms a clean room class according to the cleanliness specification based on the number of passing fine particles.

[0029] In addition, the cloud computing service device 4 performs intelligent calculations on the air pollution data stored therein to determine the safe detection value of air pollution, and based on this, transmits control commands to the gas exchange device 3 and the purifier 2 to start and operate them.
