Description

[Technical field]

[0001] The present invention relates to an indoor air pollution control system, and more particularly to an indoor air pollution control system suitable for implementation in various areas of a room. [Background technology]

[0002] Suspended particulates refer to solid particles or liquid droplets contained in gas. Because the particle size is very small, they can easily enter the human lungs through the nasal hairs in the nasal cavity, causing lung inflammation, asthma, cardiovascular disease, etc., and if other pollutants adhere to the suspended particulates, the harm to the respiratory system becomes even greater. In recent years, the problem of air pollution has become increasingly serious, and the concentration data of fine suspended particles (e.g., PM2.5) in particular is often too high, so monitoring the concentration of suspended particulates in gas has attracted attention. However, the flow of gas is unstable depending on the wind direction and volume, and most of the gas monitoring stations that currently detect suspended particulates are fixed-point type, so it is not possible to immediately check the concentration of suspended particulates in the surrounding area.

[0003] In addition, modern people are increasingly placing importance on the quality of the air around them, and gases such as carbon monoxide, carbon dioxide, volatile organic compounds (VOCs), PM2.5, nitrogen monoxide, sulfur monoxide, and even the fine particles contained in gases are all exposed to the environment, affecting human health and, in severe cases, even threatening life. Therefore, the quality of environmental gases has attracted the attention of many countries, and how to detect gas quality and avoid areas with poor gas quality or keep away from areas with poor gas quality is currently a hot topic.

[0004] As a way to check the quality of gas, gas sensors can be used to detect the surrounding environmental gases. If the detection information can be provided in real time to alert people in the environment, so that the impacts and injuries on human health caused by environmental gas hazards can be prevented or avoided in real time, it is a very good application of using gas sensors to detect the surrounding environment.

[0005] In addition, indoor air quality is difficult to grasp, and in addition to outdoor air quality, indoor air conditioning conditions and pollution sources are all major factors that affect indoor air quality. How to intelligently and quickly detect indoor air pollution sources in various areas of the room, effectively remove indoor air pollution, form a clean and safe gas state, and monitor indoor air quality in real time at any time and anywhere, and when indoor air quality is poor, quickly purify indoor air, intelligently generate gas convection in the indoor space, quickly detect and identify the location of indoor air pollution areas, effectively control multiple filtering devices to intelligently implement gas convection, accelerate the direction of air pollution, and filter and remove indoor air pollution sources, so that indoor air pollution is in the form of air pollution location identification-air pollution guide-air pollution complete removal, and reach a clean and safe air state, is the main task of the research and development of the present invention. Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention is an indoor air pollution prevention system. Because indoor air pollution occurs and moves from time to time, the present invention mainly arranges multiple gas detectors in various areas outdoors and indoors, so that the gas detectors identify the nature, concentration and location of the air pollution, output and form air pollution information, arrange an intake filter device in the intake passage of the gas exchange device, and arrange an exhaust filter device in the exhaust passage, and the cloud computing service device receives the air pollution information of the indoor area unit and the outdoor area unit, stores it in the air pollution data database, performs artificial intelligence calculation to identify the location of the air pollution, issues a control command, and sends it to the intake filter device and the exhaust filter device to start operation, so as to not only intelligently and selectively exchange the indoor and outdoor air, but also generate a directional airflow in the indoor area unit, quickly guide, filter and remove the air pollution, and achieve the effects of detection, purification and prevention of indoor air pollution for air pollution location identification-air pollution guide-air pollution complete removal.

[0009] The following description will provide detailed descriptions of the embodiments showing the features and advantages of the present invention. It should be understood that the present invention can have various modifications in different aspects, all without departing from the scope of the present invention, and the description and drawings are illustrative in nature, and are not intended to limit the present invention.

[0010] 1A and 1B, the present invention is an indoor air pollution prevention system including at least one indoor area unit A, a gas exchange device H, a plurality of gas detectors 3, and a cloud computing service device B.

[0011] The above indoor area unit A is a space surrounded and isolated by a plurality of partition members L. In this embodiment, the indoor area unit A can be an indoor space formed in a general residential building, including a living room A1, a bedroom A2, a family room A3, an office A4, a conference room A5, a tea room A6, a dressing room A7, a kitchen A8, a toilet A9, etc. (as shown in FIG. 1B). The indoor area unit A of the indoor air pollution prevention system of the present invention can include spaces separated by all indoor areas, and in some embodiments, the indoor area unit A may be an indoor space formed in a public building, including, but not limited to, a gymnasium, a concert hall, a theater, an exhibition space, a hospital space, an airport space, a station space, etc.

[0012] The gas exchange device H is configured to exchange indoor and outdoor air, and includes at least one intake passage H1 and at least one exhaust passage H2, the intake passage H1 and the exhaust passage H2 communicate with the indoor area unit A, the intake passage H1 is installed in the indoor area unit A so as to introduce outdoor air, and the exhaust passage H2 is installed in the indoor area unit A so as to discharge indoor air. An intake filter device D1 is embedded at a position where the intake passage H1 communicates with the partition member L of the indoor area unit A, and as shown in FIG. 2A, the intake filter device D1 includes at least one air guide device 1, at least one filtering part 2, and a gate G. When the air guide device 1 is started, the gate G opens, and the outdoor air in the intake passage H1 is guided by the air guide device 1, filtered and removed by the filtering part 2, and enters the indoor area unit A. An exhaust filter device D2 is embedded at a position where the exhaust passage H2 communicates with the partition member L of the indoor area unit A, and as shown in Figure 2B, the exhaust filter device D2 includes at least one air guide device 1, at least one filtering part 2, and a gate G. When the air guide device 1 is activated, the gate G opens and the indoor air of the indoor area unit A is guided to the exhaust passage H2 by the air guide device 1, where it is filtered and removed by the filtering part 2 and discharged outside.

[0013] The air guide device 1 has a function of transporting gas in both exhaust and air supply directions, and the exhaust or air supply direction is set based on the airflow path (the direction shown by the arrow in FIG. 2A). The air guide device 1 may be installed in front of the filtering part 2, or may be installed in the rear of the filtering part 2, or may be installed in front and rear of the filtering part 2 (as shown in FIG. 2A). In the embodiment shown in FIG. 2A and FIG. 2B, there are two air guide devices 1, which are installed in front and rear of the filtering part 2, respectively, but this is not limited. As shown in FIG. 2A, an intake filter device D1 is incorporated in the intake passage H1, and the air guide device 1 and the filtering part 2 of the intake filter device D1 can be replaced, updated, and maintained, and as shown in FIG. 2B, an exhaust filter device D2 is incorporated in the exhaust passage H2, and the air guide device 1 and the filtering part 2 of the exhaust filter device D2 can be replaced, updated, and maintained.

[0014] Refer to FIG. 2C. The filtering part 2 is a filter screen. The filter screen removes air pollution by physical methods of blocking and adsorption. The filter 2 is a high-efficiency filter screen 2a, which adsorbs chemical smog, bacteria, dust particles and pollen contained in the air pollution, thereby achieving the effect of filtering and purifying the introduced air pollution. The filtering part 2 chemically removes air pollution by applying a decomposition layer 21 to the high-efficiency filter screen 2a. The decomposition layer 21 is activated carbon 21a, which removes organic and inorganic matter in air pollution and removes colored substances and odorous substances. The decomposition layer 21 is a chlorine dioxide purifying factor 21b, which inhibits viruses, bacteria, fungi, influenza A virus, influenza B virus, enteric virus and norovirus in air pollution, and the inhibition rate reaches more than 99%, which contributes to reducing cross-infection of viruses. The decomposition layer 21 is a herbal protective layer 21c containing ginkgo and Japanese water chestnut (Rhus chinensis), which effectively resists allergies and destroys the surface protein of influenza viruses (e.g., H1N1). The decomposition layer 21 is silver ions 21d, which inhibits viruses, bacteria, and fungi in the introduced air pollution. The decomposition layer 21 is zeolite 21e, which removes ammonia nitrogen, heavy metals, organic pollutants, E. coli, phenol, chloroform, and anionic surfactants. In some embodiments, the filtration component 2 combines with light irradiation 22 to chemically remove air pollution. The light irradiation 22 is a photocatalyst unit including a photocatalyst 22a and an ultraviolet lamp 22b, and when the photocatalyst 22a is irradiated by the ultraviolet lamp 22b, it converts light energy into electrical energy, which decomposes harmful substances in air pollution for disinfection and sterilization, thereby achieving the effect of filtering and purifying.The light irradiation 22 is an optical plasma unit including optical nanotubes 22c, and by irradiating the introduced air pollution with the optical nanotubes 22c, the oxygen molecules and water molecules in the air pollution are decomposed into optical plasma having high oxidizing properties, forming an ion airflow having destroyed organic molecules, and decomposing gas molecules such as volatile formaldehyde, toluene, and volatile organic gases (VOCs) contained in the air pollution into water and carbon dioxide, thereby achieving the effect of filtering and purifying. In some embodiments, the filtering part 2 can also be combined with a decomposition unit 23 to chemically remove air pollution. The decomposition unit 23 is a negative ion unit 23a, which attaches positively charged fine particles contained in the introduced air pollution to a negatively charged dust collecting plate, thereby achieving the effect of filtering and purifying the introduced air pollution. The decomposition unit 23 is a plasma ion unit 23b, which ionizes oxygen molecules and water molecules contained in the air pollution with plasma ions to turn them into positive ions (H. + ) and anions (O 2- ) and the substances with water molecules attached around the ions attach to the surface of viruses and bacteria, where they are converted into powerful oxidizing active oxygen (hydroxyl group, OH group) through a chemical reaction, which steals hydrogen from the surface proteins of the viruses and bacteria and oxidizes and decomposes them, thereby achieving the effect of filtering and purifying the introduced air pollution.

[0015] 1B, as for the plurality of gas detectors 3, at least one gas detector 3 arranged in the outdoor area unit C detects and determines the nature, concentration, and location of outdoor air pollution, and outputs and forms air pollution information, and at least one gas detector 3 arranged in each indoor area unit A detects and determines the nature, concentration, and location of indoor air pollution, and outputs and forms air pollution information.

[0016] Please refer to Figures 1A, 1B, 3A, and 3B. The indoor air pollution prevention system of the present invention detects and determines the nature, concentration and location of indoor and outdoor air pollution by multiple gas detectors 3 in the indoor area unit A and the outdoor area unit C, outputs and forms air pollution information, the filtering part 2 filters the passing air pollution, and the air guide device 1 guides the air pollution to be filtered and removed by the filtering part 2. The cloud computing service device B receives the air pollution information of the indoor area unit A and the outdoor area unit C, stores it in an air pollution data database, performs artificial intelligence calculations to identify the location of the air pollution, issues control commands and sends them to multiple exhaust filter devices D2 in the indoor area unit A to control the start-up operation of the air guide device 1 of the exhaust filter device D2 closest to the location of the air pollution location, and opens the gate G to generate a directional airflow. Then, it controls the start-up operation of the air guide device 1 of the other exhaust filter devices D2, and opens the gate G to quickly guide the air pollution in the indoor area unit A to the filtering part 2 of the multiple exhaust filter devices D2 to filter and remove it, thereby forming an air condition that reduces the air pollution in the indoor area unit A to zero.

[0017] The above air pollution refers to any one or combination of suspended particulate matter, carbon monoxide, carbon dioxide, ozone, sulfur dioxide, nitrogen dioxide, lead, total volatile organic compounds, formaldehyde, bacteria, fungi, and viruses.

[0018] Refer to FIG. 12. The cloud computing service device B includes a wireless network cloud computing service module B1, a cloud control service unit B2, a device management unit B3, and an application unit B4. The wireless network cloud computing service module B1 receives air pollution information of the indoor area unit A, receives communication information of the air guide device 1, and sends a control command. The air pollution information of the indoor area unit A received by the wireless network cloud computing service module B1 is sent to the cloud control service unit B2 to form and store a database of air pollution data, and an artificial intelligence calculation is performed to identify the location of air pollution by comparing the database of air pollution data, and a control command is issued and sent to the wireless network cloud computing service module B1, and sent to the air guide device 1 of the intake filter device D1 and the exhaust filter device D2 via the wireless network cloud computing service module B1 to control the start-up operation and open the gate G. The device management unit B3 can receive communication information of the air guide device 1 via the wireless network cloud computing service module B1 for user login management and device binding management, and provide device management information to the application unit B4 for system control management. The application unit B4 displays and notifies the air pollution information obtained by the cloud control service unit B2, so that the user can grasp the air pollution removal status in real time via the mobile phone or communication device, and control the operation of the indoor air pollution prevention system via the application unit B4 of the mobile phone or communication device.

[0019] As can be seen from the above explanation, the multiple gas detectors 3 are installed in the indoor area unit A to detect the nature and concentration of indoor air pollution, and are installed in the outdoor area unit C to detect the nature and concentration of outdoor air pollution. When the indoor area unit A is any of the area units of living room A1, bedroom A2, family room A3, office A4, conference room A5, tea room A6, dressing room A7, gymnasium, concert hall, theater, exhibition space, hospital space, airport space, and station space, the cloud computing service device B receives and compares the detected air pollution information of the indoor area unit A and the air pollution information of the outdoor area unit C, and when the air pollution information of the indoor area unit A is higher than the air pollution information of the outdoor area unit C, the cloud computing service device B issues the control command to control the start-up operation of the air guide device 1 of the intake filter device D1 and the exhaust filter device D2, and when the air guide device 1 is started, the gate G opens and guides the outdoor air to the indoor area unit A through the intake passage H1, and guides the air pollution of the indoor area unit A to be discharged to the outside through the exhaust passage H2, thereby replacing the air of the indoor area unit A and forming an air condition that makes the air pollution zero.

[0020] The indoor area unit A is one of the area units of the living room A1, bedroom A2, family room A3, office A4, conference room A5, tea room A6, dressing room A7, gymnasium, concert hall, theater, exhibition space, hospital space, airport space, and station space. The cloud computing service device B receives and compares at least two or more pieces of air pollution information detected by the multiple gas detectors 3 of the indoor area unit A, performs intelligent calculations to determine and identify the location of the air pollution in the indoor area unit A, intelligently and selectively issues a control command, transmits it to the air guide device 1 of the exhaust filter device D2, controls the start-up operation of the air guide device 1 closest to the location of the air pollution, and then controls the start-up operation of the other air guide devices 1 to generate a directional airflow, quickly guide the air pollution to the filtering part 2 for filtering and removing, and quickly eliminates the air pollution in the indoor area unit A to form a clean and breathable air state. In a specific embodiment, as shown in FIG. 1C, a gas detector 3 is installed in an indoor area unit A to detect suspended particulate matter PM2.5. When a user activates the indoor air pollution prevention system before 7:40, the value of suspended particulate matter PM2.5 in the indoor area unit A is close to the value of suspended particulate matter PM2.5 in the outdoor area unit C. When the indoor air pollution prevention system is activated at 7:40, the gas detector 3 in the indoor area unit A detects suspended particulate matter PM2.5. At the same time, the cloud computing service device B receives and compares at least two or more pieces of air pollution information detected by the multiple gas detectors 3 in the indoor area unit A, performs intelligent calculations to determine and identify the location of air pollution in the indoor area unit A, intelligently and selectively issues a control command and sends it to the air guide device 1 to control the starting operation of the air guide device 1 closest to the location of air pollution, and then controls the starting operation of the other air guide devices 1, and opens the gate G to generate a directional airflow, and quickly guides the air pollution to the filtering part 2 for filtering and removing. At 7:44, the air pollution value for the entire indoor area unit A dropped sharply, and it can be seen that the effect of achieving zero air pollution continued thereafter.

[0021] In addition, the indoor area unit A is an area unit of the kitchen A8, and the indoor area unit A is equipped with a range hood 4, and the range hood 4 is connected to the exhaust passage H2. The cloud computing service device B receives and compares the air pollution information detected by the gas detector 3 of the indoor area unit A, and when the data of the air pollution information exceeds the safety detection value, it intelligently and selectively issues a control command and transmits it to the range hood 4 of the indoor area unit A to start operating, and quickly guides the air pollution to be discharged outside, forming an air condition that makes the air pollution of the indoor area unit A zero. In addition, the gas detector 3 is installed in the range hood 4, and the data of the air pollution information is the detection value of oil smoke, VOC, and polycyclic aromatic hydrocarbons, and when the data of the air pollution information exceeds the set safety detection value, it issues a control command and transmits it to the range hood 4 of the indoor area unit A to start operating.

[0022] In addition, the indoor area unit A is an area unit of the toilet A9, and the indoor area unit A is equipped with an exhaust fan 5, and the exhaust fan 5 is connected to the exhaust passage H2. The cloud computing service device B receives and compares the air pollution information detected by the gas detector 3 of the indoor area unit A, and when the data of the air pollution information exceeds the safety detection value, intelligently and selectively issues a control command and transmits it to the exhaust fan 5 to start its operation, quickly guides the air pollution to be discharged outside, forms an air condition that reduces the air pollution in the indoor area unit A to zero, and controls the temperature and humidity in the indoor area unit A. In addition, the gas detector 3 is installed in the exhaust fan 5, and the data of the air pollution information is CO 2 , VOC, PM2.5, and temperature and humidity detection values, and if the air pollution information data exceeds the set safety detection values, a control command is issued and sent to the exhaust fan 5 of the indoor area unit A to start operation.

[0023] The above safety detection values ​​include suspended particulate matter 2.5 (PM 2.5 ) at a concentration of 10 μg / m 3 Less than 10 ... 2) 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 9 ppm, ozone concentration less than 0.06 ppm, lead concentration less than 0.15 μg / m 3 This includes being less than.

[0024] In order to understand the embodiment of the indoor air pollution prevention system of the present invention, the structure of the gas detector 3 of the present invention will be described in detail below.

[0025] With reference to Figs. 3A to 11, the gas detector 3 of the present invention will be described below with the reference numeral 3. A gas detection module is provided inside the gas detector 3, and the gas detection module includes a control circuit board 31, a gas detection main body 32, a microprocessor 33, and a communication device 34. The gas detection main body 32, the microprocessor 33, and the communication device 34 are packaged and integrally formed in the control circuit board 31, and are electrically connected to each other. The microprocessor 33 and the communication device 34 are installed on the control circuit board 31, and the microprocessor 33 outputs a drive signal to control the detection operation of the gas detection main body 32, so that the gas detection main body 32 detects air pollution and outputs detection information, and the detection information is received by the microprocessor 33, processed and output, provided to the communication device 34 for external communication, and transmitted to the cloud computing service device B.

[0026] 4A to 9A. The gas detection main body 32 includes a base 321, a piezoelectric actuator 322, a driving 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 area 3213, an intake groove 3214, an air-conducting component installation area 3215, and an exhaust groove 3216. The first surface 3211 and the second surface 3212 are two surfaces that are installed opposite each other. The laser component 324 is formed by hollowing out from the first surface 3211 toward the second surface 3212. The outer lid 326 covers the base 321, and has a side plate 3261 that has an intake frame port 3261a and an exhaust frame port 3261b. The intake groove 3214 is recessed from the second surface 3212 and is adjacent to the laser installation area 3213. The intake groove 3214 is provided with an intake port 3214a that communicates with the outside of the base 321 and corresponds to the intake frame port 3261a of the outer lid 326, and both side walls of the intake groove 3214 are penetrated by light transmission windows 3214b and communicates with the laser installation area 3213. Thus, the first surface 3211 of the base 321 is covered with the outer lid 326, and the second surface 3212 is covered with the drive circuit board 323, thereby defining an intake path by the intake groove 3214.

[0027] The air-conducting component mounting area 3215 is recessed from the second surface 3212, communicates with the intake groove 3214, has a vent hole 3215a penetrating the bottom surface, and has positioning protrusions 3215b at each of the four corners of the air-conducting component mounting area 3215. The exhaust groove 3216 is provided with an exhaust vent 3216a that is installed corresponding to the exhaust frame opening 3261b of the outer lid 326. The exhaust groove 3216 includes a first section 3216b recessed in a vertical projection area of ​​the first surface 3211 onto the air-conducting component mounting area 3215, and a second section 3216c hollowed out from the first surface 3211 to the second surface 3212 in an area extending from the vertical projection area of ​​the air-conducting component mounting area 3215, and the first section 3216b is connected to the second section 3216c to form a step. A first section 3216b of the exhaust groove 3216 communicates with the ventilation hole 3215a of the air-conducting component mounting area 3215, and a second section 3216c of the exhaust groove 3216 communicates with the exhaust vent 3216a. Thus, when the first surface 3211 of the base 321 is covered with the outer lid 326 and the second surface 3212 is covered with the drive circuit board 323, the exhaust groove 3216 and the drive circuit board 323 together define an exhaust path.

[0028] The laser component 324 and the particle sensor 325 are both installed on the drive circuit board 323 and located in the base 321, and the drive circuit board 323 is intentionally omitted in order to clearly explain the positions of the laser component 324, the particle sensor 325, and the base 321. The laser component 324 is accommodated in the laser installation area 3213 of the base 321, and the particle sensor 325 is accommodated in the intake groove 3214 of the base 321 and aligned with the laser component 324. In addition, the laser component 324 corresponds to the light transmission window 3214b through which the laser light emitted by the laser component 324 passes, thereby irradiating the laser light to the intake groove 3214. The beam path emitted by the laser component 324 passes through the light transmission window 3214b and is perpendicular to the intake groove 3214. The beam emitted by the laser component 324 passes through the light transmission window 3214b and enters the intake groove 3214, irradiating the gas in the intake groove 3214. When the beam comes into contact with the gas, it scatters to generate a projection spot, and the particle sensor 325 is located at a position perpendicular to the gas sensor, receives the scattered projection spot and performs calculations to obtain gas detection data. In addition, the gas sensor 327 is positioned and installed on the driving circuit board 323, electrically connected to the driving circuit board 323, and is housed in the intake groove 3214 to detect air pollution introduced into the intake groove 3214.

[0029] The piezoelectric actuator 322 is accommodated in a square air-conducting component mounting area 3215 of the base 321. The air-conducting component mounting area 3215 is connected to the air intake groove 3214. When the piezoelectric actuator 322 is activated, the gas in the air intake groove 3214 is sucked into the piezoelectric actuator 322, and the gas passes through the air vent 3215a of the air-conducting component mounting area 3215 and enters the exhaust groove 3216. The driving circuit board 323 covers the second surface 3212 of the base 321. The laser component 324 is installed and electrically connected to the driving circuit board 323. The particulate sensor 325 is also installed and electrically connected to the driving circuit board 323. When the outer cover 326 covers the base 321, the air intake frame opening 3261a corresponds to the air intake vent 3214a of the base 321, and the exhaust frame opening 3261b corresponds to the exhaust vent 3216a of the base 321.

[0030] 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, and the hollow hole 3221b penetrates the center of the suspension plate 3221a to allow gas to 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.

[0031] The chamber housing 3222 is stacked on the gas orifice plate 3221, and its appearance corresponds to the gas orifice plate 3221. The actuator 3223 is stacked on the chamber housing 3222, and defines a resonant chamber 3226 between the gas orifice plate 3221 and the suspension plate 3221a. The insulating housing 3224 is stacked on the actuator 3223, and its appearance is similar to the chamber housing 3222. The conductive housing 3225 is stacked on the insulating housing 3224, and its appearance is similar to 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. 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 housed in an insulating housing 3224. The conductive electrode 3225b of the conductive housing 3225 is electrically connected to the piezoelectric plate 3223c. In a preferred embodiment of the present invention, the piezoelectric carrier plate 3223a and the resonance adjustment plate 3223b are both made of 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 driving circuit (not shown) on the driving circuit board 323 to receive a driving signal (which may be a driving frequency and a driving voltage). The driving 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, and the insulating housing 3224 can cut off the conductive housing 3225 and the actuator 3223 to prevent a short circuit phenomenon, and the driving signal can be transmitted to the piezoelectric plate 3223c. After receiving the driving signal, the piezoelectric plate 3223c is deformed by the piezoelectric effect, and further drives the piezoelectric carrier plate 3223a and the resonance adjustment plate 3223b to generate a reciprocating bending vibration.

[0032] More specifically, the resonance adjustment plate 3223b is located between the piezoelectric plate 3223c and the piezoelectric carrier plate 3223a as a buffer between them, and can adjust the vibration frequency of the piezoelectric carrier plate 3223a. Basically, the thickness of the resonance adjustment plate 3223b is greater 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.

[0033] Please refer to Figures 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 stacked and positioned in order in the air-conducting component mounting area 3215, so that the piezoelectric actuator 322 is positioned in the air-conducting component mounting area 3215, and the piezoelectric actuator 322 defines a gap 3221c for gas flow between the suspension plate 3221a and the inner edge of the air-conducting component mounting area 3215. An airflow chamber 3227 is formed between the gas orifice plate 3221 and the bottom surface of the air-conducting component mounting area 3215. The airflow chamber 3227 is connected to a resonant chamber 3226 between the actuator 3223, the chamber housing 3222, and the suspension plate 3221a of the gas orifice plate 3221 via a hollow hole 3221b in the gas orifice plate 3221. By making the vibration frequency of the gas in the resonant chamber 3226 the same as the vibration frequency of the suspension plate 3221a, the resonant chamber 3226 and the suspension plate 3221a generate a Helmholtz resonance effect, thereby improving the gas transport efficiency. When the piezoelectric plate 3223c moves away from the bottom surface of the air-conducting 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-conducting component mounting area 3215, causing the volume of the airflow chamber 3227 to expand suddenly, the internal pressure to decrease and generate negative pressure, and gas outside the piezoelectric actuator 322 is sucked in and flows in through the gap 3221c, passes through the hollow hole 3221b, and enters the resonating chamber 3226, increasing the air pressure in the resonating chamber 3226 and generating a pressure gradient. When the piezoelectric plate 3223c moves the suspension plate 3221a of the gas orifice plate 3221 to the bottom surface of the air-conducting component mounting area 3215, the gas in the resonance chamber 3226 quickly flows out through the hollow hole 3221b, squeezing out the gas in the airflow chamber 3227, and the merged gas is quickly and in large quantities ejected in an ideal gas state close to Bernoulli's theorem, and introduced into the ventilation hole 3215a of the air-conducting component mounting area 3215.

[0034] 9B and 9C, the piezoelectric plate 3223c vibrates back and forth, and according to the principle of inertia, when the internal pressure of the resonating chamber 3226 after exhaust becomes lower than the equilibrium pressure, the gas is guided back into the resonating chamber 3226. In this way, the vibration frequency of the gas in the resonating chamber 3226 is controlled to be the same as the vibration frequency of the piezoelectric plate 3223c, thereby generating the Helmholtz resonance effect and realizing high-speed and large-volume gas transport. All the gas enters from the intake frame port 3261a of the outer cover 326, passes through the intake vent 3214a, enters the intake groove 3214 of the base 321, and flows to the position of the particle sensor 325. In addition, the gas in the intake path is absorbed by the continuous driving of the piezoelectric actuator 322, so that the external gas is rapidly introduced and stably flows, and passes above the particle sensor 325. At this time, the beam emitted by the laser component 324 passes through the light transmission window 3214b and enters the intake groove 3214, and the intake groove 3214 passes above the particle sensor 325. When the beam of the laser component 324 is irradiated on the suspended particles in the gas, a scattering phenomenon and a projection spot are generated, so that the particle sensor 325 receives the projection spot caused by scattering and performs calculations to obtain related information such as the particle diameter or concentration of the suspended particles contained in the gas. The gas above the particle sensor 325 is also introduced into the ventilation hole 3215a of the air guide 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, the piezoelectric actuator 322 continues to transport the gas to the exhaust groove 3216, so that the gas in the exhaust groove 3216 is pushed out and discharged to the outside through the exhaust vent 3216a and the exhaust frame port 3261b.

[0035] The gas detector 3 of the present invention can not only detect suspended particles in the gas, but also detect the characteristics of the introduced gas, such as formaldehyde, ammonia, carbon monoxide, carbon dioxide, oxygen gas, ozone, etc. Therefore, the gas detector 3 of the present invention further includes a gas sensor 327, which is positioned and installed on the driving circuit board 323 and electrically connected thereto, and is housed in the exhaust groove 3216, and detects the concentration or characteristics of volatile organic compounds contained in the gas led out from the exhaust path.

[0036] As described above, the present invention provides an indoor air pollution prevention system to solve the problem that indoor air pollution occurs and moves at any time and is difficult to grasp. The present invention provides a system for preventing indoor air pollution, by disposing a plurality of gas detectors in various areas outdoors and indoors, and by using the gas detectors to identify the nature, concentration and location of the air pollution, outputting and forming air pollution information, disposing an intake filter device in the intake passage of the gas exchange device, and disposing an exhaust filter device in the exhaust passage, and the cloud computing service device receives the air pollution information of the indoor area unit and the outdoor area unit, stores it in an air pollution data database, performs artificial intelligence calculations to identify the location of the air pollution, issues a control command, and sends it to the intake filter device and the exhaust filter device to start operation, thereby not only can the indoor and outdoor air be intelligently and selectively exchanged, but also generates a directional airflow in the indoor area unit to quickly guide, filter and remove air pollution, and has the functions of detecting, purifying and preventing indoor air pollution to identify the location of air pollution, guide air pollution and completely remove air pollution, and has very high industrial applicability.
