Description

[Technical field]

[0001] The present invention relates to an indoor air purification system, and in particular to an indoor air purification system suitable for forming a clean room grade by a cleanliness specification of the number of particles in the gas state in the indoor field. [Background technology]

[0002] Suspended particulate matter refers to solid particles or liquid droplets contained in the gas. Due to its very fine particle size, it is easy for it to enter the human lungs through the nasal hair in the nasal cavity, thus causing lung inflammation, asthma or cardiovascular disease. If other pollutants are attached to the suspended particulate matter, it will aggravate the harm to the respiratory system. In recent years, the problem of gas pollution has become increasingly serious, especially the concentration data of fine suspended particulate matter (such as PM2.5) is often too high. The monitoring of the concentration of gas suspended particulate matter has gradually received attention. However, since the gas will flow unstably with the wind direction and wind volume, and the gas quality monitoring stations that currently detect suspended particulate matter are mostly fixed points, it is impossible to confirm the concentration of suspended particulate matter in the surrounding area.

[0003] In addition, modern people are paying more and more attention to the quality of the air around them. For example, carbon monoxide, carbon dioxide, volatile organic compounds (VOC), PM2.5, nitrogen monoxide, sulfur monoxide and other gases, and even the particles contained in the gases, will be exposed in the environment and affect human health, and even endanger life in serious cases. Therefore, the quality of environmental gases has attracted the attention of all countries. How to detect gas quality to avoid and stay away from areas with poor gas quality is a current issue of concern.

[0004] How to confirm the quality of gas? It is feasible to use a gas sensor to detect the surrounding gas. If it can provide detection information in real time to warn people in the environment, so that they can take real-time precautions or escape, and avoid being harmed by the gas in the environment and causing health effects and injuries to the human body, using a gas sensor to detect the surrounding environment can be said to be a very good application.

[0005] In addition, indoor air quality is not easy to grasp. In addition to outdoor air quality, indoor air conditioning conditions and pollution sources are the main factors affecting indoor air quality. Indoor air pollution sources can be intelligently and quickly detected in various indoor fields, effectively removing indoor air pollution to form a clean and safe gas state, and real-time monitoring of indoor air quality anytime and anywhere. Of course, if the indoor field can strictly control the concentration of suspended particulates in the air according to the "clean room" standard, strive to avoid the introduction, generation and retention of particles, and control its temperature and humidity within the required range, that is, the indoor field can distinguish their levels by the number of suspended particles in the air, and meet the clean room requirements of indoor fields that can be safely breathed.

[0006] At present, the main application field of clean rooms is industrial environment, which means setting up a low-pollution indoor space in the production facility and removing pollutants such as dust particles in the air within the space to obtain a fairly clean environment. There are pollution levels for suspended particles in the air, and their levels are distinguished by the number of suspended particles with a diameter of ≧0.5μm in 1 cubic foot of air. In addition, clean rooms have particularly strict requirements on indoor temperature, humidity and cleanliness, so they must be controlled within a certain range to meet the required process production and operating environment. The disadvantages of traditional clean rooms used in industrial environments are high cost, huge engineering and power consumption, and they are not suitable for ordinary families, offices, schools, restaurants and public places.

[0007] In addition, clean rooms in traditional industrial environments are generally not equipped with sensors to detect air pollution in real time around the clock, so they need to operate at high speed 24 hours a day. This operation mode will result in a large amount of energy loss and a high-noise environment. Such clean room systems cannot be used in ordinary indoor home life.

[0008] How to detect the indoor air quality in the indoor space of ordinary families, offices, schools, restaurants and public places, and how to solve the air pollution problem, so that the indoor space can meet the requirements of a clean room and avoid the impact and harm to human health caused by the gas hazards in the environment. Therefore, the present invention provides an indoor air purification system, which is the main subject developed by the present invention. [Summary of the invention]

[0009] The main purpose of the present invention is to provide an indoor air purification system that produces indoor air quality that is as clean as that of clean rooms traditionally used in industrial environments. In the indoor field, a circulating return air channel is used in combination with a circulating filter device, a gas exchange device, an exhaust device, an exhaust fan and other devices, and a gas detector and an intelligent cloud are configured in the indoor field and the outdoor field to form an intelligent linkage system. The gas detectors configured in the indoor field and the outdoor field detect the PM2.5 concentration / particle number of air pollution, carbon dioxide (CO2) and volatile organic compound (VOC) information and receive cloud computing and comparison, and then intelligently select and automatically adjust the operating speed of the circulating filter device to quickly purify the pollution source and provide quiet and efficient operation. At the same time, the linkage control of the device is used to quickly deal with sudden pollution. Therefore, the indoor air purification system of this case produces indoor air quality that is as clean as that of clean rooms traditionally used in industrial environments, and there is no need to wear dust-proof clothing. It is currently the only system that can be used in general indoor living life and can provide clean room-like air quality.

[0010] To achieve the above-mentioned purpose, the present invention provides an indoor air purification system, comprising: a plurality of gas detectors, arranged in an outdoor field and an indoor field to detect air pollution information, the gas detector outputting the air pollution information through Internet of Things communication; at least one circulating return air channel, surrounded and isolated by a plurality of partitions and formed on the side of the indoor field, and provided with a plurality of air intake ports and a plurality of return air intake ports; at least one circulating filter device, arranged in the circulating return air channel and corresponding to the air intake port, and the circulating filter device comprising a fan, a filter component, a gas detector and a drive control component, the gas detector receiving a control instruction to the drive control component through Internet of Things communication to control the start of the operation of the fan, the fan is controlled to start and guide the air pollution to pass through the filter component for filtration, and discharge it from the air intake port into the space of the indoor field; at least one air conditioning device, arranged in the indoor field to adjust the temperature and humidity, comprising a gas A gas detector and a drive control component, the gas detector receives a second control instruction to the drive control component through the Internet of Things communication to control the start-up operation of the air-conditioning device, and the gas detector transmits a gas temperature and humidity information in the indoor field to the outside, and; a cloud computing service device, which receives the air pollution information of the outdoor field and the indoor field through the Internet of Things communication to store and form a big data database of air pollution data, and receives the gas temperature and humidity information output by the air-conditioning device, and intelligently calculates and compares the big data database of air pollution data and the gas temperature and humidity information, and intelligently selects to send a control instruction to the fan of the circulation filtering device to start the regulation operation, so that the indoor field continuously generates an internal circulation directional airflow, and the air pollution is repeatedly drained and filtered through the filter component, so that the gas state of the indoor field can reach the formed clean room grade through the cleanliness specification of the number of suspended particulate particles.

[0013] Embodiments that embody 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 variations in different aspects without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0014] See also Figure 1A and Figure 1B As shown, the present invention is an indoor air purification system, comprising a plurality of gas detectors a, at least one circulating return air channel C, at least one circulating filter device 2, at least one air conditioning device 3 and a cloud computing service device 4.

[0015] The above-mentioned multiple gas detectors a are arranged in an indoor field A and an outdoor field B to detect air pollution information, and the gas detector a outputs the air pollution information through the Internet of Things communication. The above-mentioned gas detector a is internally provided with a gas detection module. It is worth noting that please refer to Figure 3A and Figure 3B As shown, the gas detector a can be a type with an external power terminal, which can be directly plugged into the power interface in the indoor field A to start the operation of air pollution detection. Figure 3CThe gas detection module type shown does not contain an external power terminal, and is directly constructed on the device (circulation filter device 2, air conditioning device 3, gas exchange device 5, exhaust device 6, exhaust fan 7), connected to a drive control component b, and receives a control instruction to the drive control component b to control the device power startup operation to detect air pollution. The above-mentioned Internet of Things (IoT) communication refers to a collective network connecting various devices and a technology that helps devices communicate with the cloud and between devices. The IoT communication can be a wired communication for connecting to the cloud computing service device 4 through a wired line. The IoT communication can be a wireless communication for communicating with the cloud computing service device 4 through a wireless connection, and the wireless communication can be one of a Wi-Fi module, a Bluetooth module, a wireless radio frequency identification module, and a near field communication module.

[0016] It is worth noting that the above-mentioned air pollution refers to 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.

[0017] The above-mentioned circulating return air channel C is surrounded and isolated by several partitions 1C and is formed on the side of the indoor field A, and is provided with multiple air inlets 2C and multiple return air inlets 3C; the above-mentioned circulating filtering device 2 is arranged in the circulating return air channel C and corresponds to the air inlet 2C, and the circulating filtering device 2 includes a fan 21, a filter component 22, a gas detector a and a drive control component b. The gas detector a receives a control instruction to the drive control component b through the Internet of Things communication to control the start-up of the operation of the fan 21. The fan 21 is controlled to start and guide the air pollution through the filter component 22 for filtration, and is discharged from the air inlet 2C to enter the space of the indoor field A.

[0018] The above-mentioned air-conditioning device 3 is arranged in the indoor field A to adjust the temperature and humidity, and includes a gas detector a and a drive control component b. When the gas detector a directly detects that the temperature and humidity exceed the set safety value, the temperature and humidity set safety value, that is, the temperature, humidity and air pollution information of the indoor field A must be maintained at the air pollution data of temperature 25℃±3℃ and humidity 50%±10%. Therefore, when the gas detector a detects that the temperature and humidity exceed the set safety value, it directly sends a control instruction to the drive control component b to control the start-up operation of the air-conditioning device 3, and adjusts the indoor field A to maintain a comfortable temperature and humidity living environment; or the cloud computing service device 4 intelligently calculates and compares the temperature and humidity set safety value of the indoor field A based on the big data database of air pollution data. When the temperature and humidity set safety value exceeds the temperature 25℃±3℃ and humidity 50%±10%, the cloud computing service device 4 intelligently chooses to send a control instruction, and receives the control instruction to the drive control component b through the Internet of Things communication through the gas detector a to control the start-up operation of the air-conditioning device 3, and adjusts the indoor field A to maintain a comfortable temperature and humidity living environment. It is worth noting that the air conditioning device 3 adjusts the indoor field A to maintain a temperature of 25°C±3°C and a humidity of 50%±10%.

[0019] The cloud computing service device 4 receives air pollution information of indoor field A and outdoor field B through Internet of Things communication to form a big data database of air pollution data, and receives the gas temperature and humidity information output by the air conditioning device 3, and intelligently calculates and compares the big data database of air pollution data and the gas temperature and humidity information, and intelligently selects to send a control instruction to the fan 21 of the circulation filter device 2 to start the control operation, so that the indoor field A continuously generates an internal circulation directional airflow, and the air pollution is filtered and removed through the filter component 22 for multiple times, so that the suspended particulate matter in the gas state of the indoor field A is less than 2.5μm in particle number, and the cleanliness specification of the clean room 1~9 (ZAPClean room 1~9) level can be achieved. It is worth noting that the above-mentioned intelligent computing includes artificial intelligence (AI) computing and edge computing.

[0020] Again, if Figure 1BAs shown, in order to prevent carbon dioxide (CO2) from affecting human health and causing harm, indoor field A can further be provided with at least one gas exchange device 5, which provides gas from outdoor field B to be introduced into indoor field A for ventilation. The gas exchange device 5 is arranged in the circulating return air channel C, and corresponds to the air inlet 2C, and is connected to an air inlet channel 51 and the gas of outdoor field B. The gas exchange device 5 includes a gas detector a and a drive control component b. When the gas detector a directly detects that the carbon dioxide (CO2) exceeds the set safety value, the carbon dioxide (CO2) air pollution information of indoor field A must maintain air pollution data below 800PPM. Therefore, when the gas detector a detects that the carbon dioxide (CO2) exceeds the set safety value, a control signal is directly issued. The cloud computing service device 4 intelligently calculates and compares the safety value set for carbon dioxide (CO2) according to the big data database of air pollution data. When the safety value set for carbon dioxide (CO2) is exceeded, the cloud computing service device 4 intelligently selects to issue a control instruction, and the gas detector a receives the control instruction through the Internet of Things communication to the driving control component b to control the start-up operation of the gas exchange device 5, so that the gas of the outdoor field B is introduced into the indoor field A for ventilation. It is worth noting that a valve 52 is provided between the gas duct 51 connected to the gas exchange device 5 and the gas connection of the outdoor field B, which is controlled by the driving control component b. When the gas detector a receives the control instruction, it transmits it to the driving control component b to control the start-up operation of the gas exchange device 5, and at the same time controls the opening of the valve 52, so that the duct duct 51 is connected to the gas of the outdoor field B, so that the gas of the outdoor field B is introduced into the indoor field A for ventilation. It is worth noting that the air pollution information detected by the indoor field A and the outdoor field B is the air pollution data of carbon dioxide (CO2). The cloud computing service device 4 receives the indoor field A and the outdoor field B through the Internet of Things communication and performs intelligent calculation and comparison based on the big data database of air pollution data. The carbon dioxide (CO2) air pollution information of the indoor field A must be maintained below 800PPM air pollution data to avoid the carbon dioxide (CO2) in the indoor field A affecting human health and harm. Moreover, when the air pollution information of the indoor field A is higher than the air pollution information of the outdoor field B, that is, the carbon dioxide (CO2) air pollution information of the indoor field A is greater than 800PPM air pollution data and the air pollution information of the indoor field A is higher than the air pollution information of the outdoor field B, the cloud computing service device 4 intelligently selects to send a control instruction to the gas detector a of the gas exchange device 5 through the Internet of Things communication for reception, and transmits it to the drive control component b to control the start-up operation of the gas exchange device 5, so as to provide the gas of the outdoor field B to be introduced into the indoor field A for ventilation. It is worth noting that the gas exchange device 5 can be a fresh air blower, but is not limited thereto.

[0021] Furthermore, when the indoor field A is a kitchen space field A1, serious air pollution will be generated relatively quickly when cooking food. In order to prevent the air pollution generated in the indoor field A from affecting human health and causing harm, it is necessary to accelerate the discharge of air pollution to the outdoor field B. Therefore, the indoor air purification system can further be provided with at least one exhaust device 6 when the indoor field A is a kitchen space field A1. The exhaust device 6 includes a gas detector a and a drive control component b. When the gas detector a of the exhaust device 6 directly detects that the suspended particulate matter 2.5 (PM2.5) air pollution setting safety value exceeds the concentration of the suspended particulate matter 2.5 (PM2.5) air pollution setting safety value is less than 10μg / m 3 At this time, the gas detector a will send a control instruction to the driving control component b to control the start-up operation of the exhaust device 6, so that the air pollution in the indoor field A is accelerated to be discharged to the outdoor field B; or the cloud computing service device 4 receives the air pollution information detected by multiple gas detectors a in the indoor field A, and compares the air pollution information of the suspended particulate matter 2.5 (PM2.5) air pollution in the kitchen space field A1 according to the intelligent calculation of the big data database of air pollution data. The concentration of the suspended particulate matter 2.5 (PM2.5) air pollution is set to a safe value of less than 10μg / m 3 , and the intelligent selection sends a control instruction to the gas detector a of the exhaust device 6 through the Internet of Things communication, which receives and transmits it to the drive control component b to control the startup operation of the exhaust device 6, so that the air pollution in the indoor field A is accelerated to be discharged to the outdoor field B.

[0022] Furthermore, when the indoor field A is a bathroom space field A2, higher temperature, humidity and air pollution will be generated in real time when taking a shower or using the toilet. In order to prevent the temperature, humidity and pollution of the indoor field A from affecting human health and causing harm, the indoor air purification system can further set at least one exhaust fan 7 when the indoor field A is a bathroom space field A2. The exhaust fan 7 includes a gas detector a and a drive control component b. When the gas detector a directly detects that the temperature and humidity set safety values ​​and the air pollution set safety values ​​are exceeded, the temperature and humidity set safety values ​​are maintained at a temperature of 25°C ± 3°C and a humidity of 50% ± 10%. The air pollution set safety values ​​maintain the concentration of total volatile organic compounds (TVOC) less than 0.56ppm and the concentration of sulfur dioxide less than 0.075ppm. Therefore, the gas detector a detects that the temperature and humidity set safety values ​​exceed the temperature and humidity set safety values ​​and the air pollution set safety values. When the temperature and humidity exceed the set safety value and the air pollution set safety value, a control instruction is directly issued to the drive control component b to control the start-up operation of the exhaust fan 7, so that the air pollution in the indoor field A is accelerated to be discharged to the outdoor field B, and the indoor field A is provided with temperature and humidity control; or the cloud computing service device 4 receives the air pollution information and temperature and humidity information detected by multiple gas detectors a in the indoor field A, and compares the air pollution information and temperature and humidity information of the bathroom space field A2 according to the big data database of air pollution data, and intelligently chooses to send a control instruction to the gas detector a of the exhaust fan 7 through the Internet of Things communication to receive and transmit it to the drive control component b to control the start-up operation of the exhaust fan 7, so that the air pollution in the indoor field A is accelerated to be discharged to the outdoor field B, and the indoor field A is provided with temperature and humidity control.

[0023] As can be seen from the above description, the indoor air purification system provided by the present invention receives the air pollution information of the indoor field A and the outdoor field B through the Internet of Things communication by the cloud computing service device 4 to store and form a big data database of air pollution data, and receives the gas temperature and humidity information output by the air conditioning device 3, and intelligently calculates and compares the big data database of air pollution data and the gas temperature and humidity information, and intelligently selects to send a control instruction to the fan 21 of the circulation filter device 2 to start the regulation operation, so that the indoor field A continuously generates an internal circulation directional airflow, and the air pollution is repeatedly drained through the filter component 22 for filtration and removal; that is, the cloud computing service device 4 calculates the indoor field A through intelligent calculation. The real-time cleanliness of the number of suspended particulate matter particles can be detected, and control instructions can be sent to multiple circulating filter devices 2 intelligently. The fan 21 of the circulating filter device 2 can be activated in a timely manner to randomly adjust the air volume and the start-up time period of the fan 21 according to the real-time cleanliness of the number of suspended particulate matter particles, thereby improving the cleanliness efficiency of the indoor field A and reducing the environmental noise of the indoor field A. The indoor field A can generate an internal circulation directional airflow, and the air pollution can be quickly drained and filtered through the filter component 22 for multiple times, so as to promote the cleanliness specification of the suspended particulate matter in the gas state of the indoor field A to be less than 2.5μm, so as to reach the clean room 1~9 (ZAPClean room 1~9) level.

[0024] like Fig.13As shown, a comparison table of clean room grades formed by the cleanliness specification of the number of suspended particles with a particle size of less than 2.5 μm required for air pollution in indoor field A is formulated. The indoor air purification system provided by the present invention can make the gas state of indoor field A such that the number of suspended particles with a particle size of less than 2.5 μm per cubic meter is less than 1 particle, meeting the cleanliness specification requirement of clean room grade 1 (ZAPClean room 1); make the gas state of indoor field A such that the number of suspended particles with a particle size of less than 2.5 μm per cubic meter is less than 10 particles, meeting the cleanliness specification requirement of clean room grade 2 (ZAPClean room 2); make the gas state of indoor field A such that the number of suspended particles with a particle size of less than 2.5 μm per cubic foot is less than 3 particles, and the number of suspended particles with a particle size of less than 2.5 μm per cubic meter is less than 100 particles, meeting the cleanliness specification requirement of clean room grade 3 (ZAPClean room 4). room3) cleanliness specification requirements; the gas state of indoor field A is that the number of suspended particles with a diameter of less than 2.5μm per cubic foot is less than 28 particles, and the number of suspended particles with a diameter of less than 2.5μm per cubic meter is less than 1000 particles, reaching the cleanliness specification requirements of clean room level 4 (ZAPClean room 4); the gas state of indoor field A is that the number of suspended particles with a diameter of less than 2.5μm per cubic foot is less than 286 particles, and the number of suspended particles with a diameter of less than 2.5μm per cubic meter is less than 10,000 particles, reaching the cleanliness specification requirements of clean room level 5 (ZAPClean room 5); the gas state of indoor field A is that the number of suspended particles with a diameter of less than 2.5μm per cubic foot is less than 2860 particles, and the number of suspended particles with a diameter of less than 2.5μm per cubic meter is less than 100,000 particles, reaching the cleanliness specification requirements of clean room level 6 (ZAPClean room 6) cleanliness specification requirements; the gas state of indoor field A is that the number of suspended particles with a diameter of less than 2.5μm per cubic foot is less than 28,600 particles, and the number of suspended particles with a diameter of less than 2.5μm per cubic meter is less than 1,000,000 particles, reaching the cleanliness specification requirements of clean room level 7 (ZAPClean room 7); the gas state of indoor field A is that the number of suspended particles with a diameter of 2.5μm per cubic foot is less than 77,200 particles, and the number of suspended particles with a diameter of less than 2.5μm per cubic meter is less than 2,720,000 particles, reaching the cleanliness specification requirements of clean room level 8 (ZAPClean room 8) cleanliness specification requirements; the gas state of indoor space A is that the number of suspended particles with a diameter of 2.5μm formed per cubic foot is less than 154,300 suspended particles passing through, and the number of suspended particles with a diameter of less than 2.5μm formed per cubic meter is less than 5,440,000 particles, meeting the cleanliness specification requirements of clean room level 9 (ZAPClean room 9).

[0025] To understand the specific implementation of the indoor air purification system provided by the present invention, the gas detection module structure of the gas detector a of the present invention is described in detail below. Figures 3A to 11 As shown, the gas detection module comprises: a control circuit board 11, a gas detection body 12, a microprocessor 13 and a communicator 14. The gas detection body 12, the microprocessor 13 and the communicator 14 are packaged in the control circuit board 11 to form a whole and are electrically connected to each other. The microprocessor 13 and the communicator 14 are arranged on the control circuit board 11, and the microprocessor 13 controls the driving signal of the gas detection body 12 to start the detection operation, so that the gas detection body 12 detects air pollution and outputs a detection information, which is then processed by the microprocessor 13 and provided to the communicator 14 for external transmission to the cloud computing service device 4 through the Internet of Things (IoT) communication.

[0026] Please see again 4A to 9A As shown, the gas detection body 12 comprises a base 121, a piezoelectric actuator 122, a driving circuit board 123, a laser assembly 124, a particle sensor 125 and an outer cover 126. The base 121 has a first surface 1211, a second surface 1212, a laser setting area 1213, an air inlet groove 1214, an air guide assembly bearing area 1215 and an air outlet groove 1216. The first surface 1211 and the second surface 1212 are two surfaces arranged opposite to each other. The laser setting area 1213 is hollowed out from the first surface 1211 toward the second surface 1212. In addition, the outer cover 126 covers the base 121 and has a side plate 1261, and the side plate 1261 has an air inlet frame 1261a and an air outlet frame 1261b. The air inlet groove 1214 is formed by being recessed from the second surface 1212 and is adjacent to the laser setting area 1213. The air inlet groove 1214 is provided with an air inlet port 1214a, which is connected to the outside of the base 121 and corresponds to the air outlet port 1216a of the outer cover 126, and the two side walls of the air inlet groove 1214 penetrate the light-transmitting window 1214b of the piezoelectric actuator 122 and are connected to the laser setting area 1213. Therefore, the first surface 1211 of the base 121 is covered by the outer cover 126, and the second surface 1212 is covered by the actuator circuit board 123, so that the air inlet groove 1214 defines an air inlet path.

[0027] The air guide component carrying area 1215 is formed by a depression of the second surface 1212, and is connected to the air inlet groove 1214, and has an air hole 1215a on the bottom surface, and each of the four corners of the air guide component carrying area 1215 has a positioning protrusion 1215b. The above-mentioned air outlet groove 1216 is provided with an air outlet port 1216a, and the air outlet port 1216a is correspondingly arranged with the air outlet frame port 1261b of the outer cover 126. The air outlet groove 1216 includes a first section 1216b formed by the vertical projection area of ​​the first surface 1211 being recessed to the air guide component bearing area 1215, and an area extending from the vertical projection area of ​​the air guide component bearing area 1215, and a second section 1216c formed by hollowing out from the first surface 1211 to the second surface 1212, wherein the first section 1216b is connected to the second section 1216c to form a step difference, and the first section 1216b of the air outlet groove 1216 is communicated with the vent hole 1215a of the air guide component bearing area 1215, and the second section 1216c of the air outlet groove 1216 is communicated with the air outlet 1216a. Therefore, when the first surface 1211 of the base 121 is covered by the outer cover 126 and the second surface 1212 is covered by the driving circuit board 123, the air outlet groove 1216 and the driving circuit board 123 jointly define an air outlet path.

[0028] The laser assembly 124 and the particle sensor 125 are both disposed on the driving circuit board 123 and located in the base 121. In order to clearly explain the positions of the laser assembly 124 and the particle sensor 125 and the base 121, the driving circuit board 123 is omitted. The laser assembly 124 is accommodated in the laser setting area 1213 of the base 121, and the particle sensor 125 is accommodated in the air inlet groove 1214 of the base 121 and aligned with the laser assembly 124. In addition, the laser assembly 124 corresponds to the light-transmitting window 1214b, and the light-transmitting window 1214b allows the laser light emitted by the laser assembly 124 to pass through, so that the laser light is irradiated to the air inlet groove 1214. The path of the light beam emitted by the laser assembly 124 is to pass through the light-transmitting window 1214b and form an orthogonal direction with the air inlet groove 1214. The laser component 124 emits a light beam through the light-transmitting window 1214b into the air intake groove 1214, and the detection data in the gas in the air intake groove 1214 is irradiated. When the light beam contacts the gas, it will scatter and generate a projected light spot, so that the particle sensor 125 is located in its orthogonal direction and receives the projected light spot generated by the scattering for calculation to obtain the detection data of the gas.

[0029] The piezoelectric actuator 122 is accommodated in the square gas guide component carrying area 1215 of the base 121. In addition, the gas guide component carrying area 1215 is connected to the air inlet groove 1214. When the piezoelectric actuator 122 is actuated, the gas in the air inlet groove 1214 is drawn into the piezoelectric actuator 122, and the gas is supplied to enter the gas outlet groove 1216 through the vent hole 1215a of the gas guide component carrying area 1215. In addition, the driving circuit board 123 is sealed on the second surface 1212 of the base 121. The laser component 124 is disposed on the driving circuit board 123 and is electrically connected. The particle sensor 125 is also disposed on the driving circuit board 123 and is electrically connected. When the outer cover 126 is covered on the base 121 , the air outlet 1216 a corresponds to the air inlet 1214 a of the base 121 , and the air outlet frame opening 1261 b corresponds to the air outlet 1216 a of the base 121 .

[0030] The piezoelectric actuator 122 comprises an air jet hole sheet 1221, a cavity frame 1222, an actuator 1223, an insulating frame 1224 and a conductive frame 1225. The air jet hole sheet 1221 is made of a flexible material and has a suspension sheet 1221a and a hollow hole 1221b. The suspension sheet 1221a is a sheet structure that vibrates in bending, and its shape and size correspond to the inner edge of the air guide component bearing area 1215, while the hollow hole 1221b runs through the center of the suspension sheet 1221a for gas circulation. In a preferred embodiment of the present invention, the shape of the suspension sheet 1221a can be one of a square, a figure, an ellipse, a triangle and a polygon.

[0031] The cavity frame 1222 is stacked on the jet hole sheet 1221, and its appearance corresponds to the jet hole sheet 1221. The actuator 1223 is stacked on the cavity frame 1222, and defines a resonance chamber 1226 between the actuator 1223, the jet hole sheet 1221, and the suspension sheet 1221a. The insulating frame 1224 is stacked on the actuator 1223, and its appearance is similar to the cavity frame 1222. The conductive frame 1225 is stacked on the insulating frame 1224, and its appearance is similar to the insulating frame 1224, and the conductive frame 1225 has a conductive pin 1225a and a conductive electrode 1225b extending outward from the outer edge of the conductive pin 1225a, and the conductive electrode 1225b extends inward from the inner edge of the conductive frame 1225. In addition, the actuator 1223 further includes a piezoelectric carrier 1223a, an adjustment resonance plate 1223b, and a piezoelectric plate 1223c. The piezoelectric carrier plate 1223a is stacked on the cavity frame 1222. The adjustment resonance plate 1223b is stacked on the piezoelectric carrier plate 1223a. The piezoelectric plate 1223c is stacked on the adjustment resonance plate 1223b. The adjustment resonance plate 1223b and the piezoelectric plate 1223c are accommodated in the insulating frame 1224. The piezoelectric plate 1223c is electrically connected to the conductive electrode 1225b of the conductive frame 1225. In a preferred embodiment of the present invention, the piezoelectric carrier plate 1223a and the adjustment resonance plate 1223b are both conductive materials. The piezoelectric carrier 1223a has a piezoelectric pin 1223d, and the piezoelectric pin 1223d and the conductive pin 1225a are connected to the driving circuit (not shown) on the driving circuit board 123 to receive the driving signal (which may be the driving frequency and the driving voltage). The driving signal can form a loop by the piezoelectric pin 1223d, the piezoelectric carrier 1223a, the adjustment resonance plate 1223b, the piezoelectric plate 1223c, the conductive electrode 1225b, the conductive frame 1225 and the conductive pin 1225a, and the insulating frame 1224 blocks 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 due to the piezoelectric effect, which further drives the piezoelectric carrier plate 1223a and the adjustment resonance plate 1223b to generate reciprocating bending vibrations.

[0032] To further illustrate, the adjustment resonance plate 1223b is located between the piezoelectric plate 1223c and the piezoelectric carrier plate 1223a, and serves as a buffer between the two to adjust the vibration frequency of the piezoelectric carrier plate 1223a. Basically, the thickness of the adjustment resonance plate 1223b is greater than that of the piezoelectric carrier plate 1223a, and the vibration frequency of the actuator 1223 is adjusted by changing the thickness of the adjustment resonance plate 1223b.

[0033] Please refer to Fig. 7A , Figure 7B , Fig. 8A , Figure 8B and Fig.9A As shown, the jet hole sheet 1221, the cavity frame 1222, the actuator 1223, the insulating frame 1224 and the conductive frame 1225 are stacked and positioned in sequence in the air guide component support area 1215, so that the piezoelectric actuator 122 is positioned in the air guide component support area 1215. The piezoelectric actuator 122 defines a gap 1221c between the suspension sheet 1221a and the inner edge of the air guide component support area 1215 for gas circulation. An airflow chamber 1227 is formed between the jet hole sheet 1221 and the bottom surface of the air guide component support area 1215. The airflow chamber 1227 is connected to the resonant chamber 1226 between the actuator 1223, the airflow hole sheet 1221 and the suspension sheet 1221a through the hollow hole 1221b of the airflow hole sheet 1221. The vibration frequency of the gas in the resonant chamber 1226 is made close to the vibration frequency of the suspension sheet 1221a, so that the resonant chamber 1226 and the suspension sheet 1221a can generate a Helmholtz resonance effect, thereby improving the gas transmission efficiency. When the piezoelectric plate 1223c moves away from the bottom surface of the air guide component supporting area 1215, the piezoelectric plate 1223c drives the suspension plate 1221a of the jet hole plate 1221 to move away from the bottom surface of the air guide component supporting area 1215, so that the volume of the airflow chamber 1227 expands rapidly, the internal pressure drops to produce negative pressure, and the gas outside the piezoelectric actuator 122 flows in through the gap 1221c and enters the resonance chamber 1226 through the hollow hole 1221b, increasing the air pressure in the resonance chamber 1226 and thus producing a pressure gradient. When the piezoelectric plate 1223c drives the suspended plate 1221a of the jet hole plate 1221 to move toward the bottom surface of the air guide component supporting area 1215, the gas in the resonance chamber 1226 quickly flows out through the hollow hole 1221b, squeezing the gas in the air flow chamber 1227, and making the converged gas quickly and massively ejected out of the air hole 1215a of the air guide component supporting area 1215 in an ideal gas state close to Bernoulli's principle.

[0034] By repetition Fig. 9B and Fig. 9CIn the action shown, the piezoelectric plate 1223c vibrates reciprocatingly. According to the inertia principle, the internal air pressure of the resonance chamber 1226 after exhaust is lower than the equilibrium air pressure, which will guide the gas 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, so as to produce the Helmholtz resonance effect and realize the high-speed and large-volume transmission of the gas. The gas enters from the air inlet 1214a of the outer cover 126, enters the air inlet groove 1214 of the base 121 through the air inlet 1214a, and flows to the position of the particle sensor 125. Furthermore, the continuous movement of the piezoelectric actuator 122 will absorb the gas in the air intake path, so as to facilitate the rapid introduction and stable circulation of external gas, and pass through the top of the particle sensor 125. At this time, the laser component 124 emits a light beam through the light-transmitting window 1214b to enter the air intake groove 1214. The air intake groove 1214 passes above the particle sensor 125. When the light beam of the particle sensor 125 irradiates the suspended particles in the gas, scattering and projected light spots will occur. When the particle sensor 125 receives the projected light spots generated by the scattering, it calculates to obtain relevant information such as the particle size and concentration of the suspended particles contained in the gas, and the gas above the particle sensor 125 is also continuously driven by the piezoelectric actuator 122 and introduced into the vent 1215a of the air guide component supporting area 1215, and enters the air outlet groove 1216. Finally, when the gas enters the gas outlet groove 1216 , since the piezoelectric actuator 122 continuously delivers the gas into the gas outlet groove 1216 , the gas in the gas outlet groove 1216 will be pushed and discharged to the outside through the gas outlet port 1216 a and the gas outlet frame port 1261 b .

[0035] The gas detector a of the present invention can not only detect suspended particles in the gas, but also further detect the characteristics of the introduced gas, such as formaldehyde, ammonia, carbon monoxide, carbon dioxide, oxygen, ozone, etc. Therefore, the gas detector a of the present invention further includes a gas sensor 127, which is positioned and electrically connected to the driving circuit board 123, and is accommodated in the gas outlet groove 1216 to detect the characteristics of the introduced gas. The gas sensor 127 can be a volatile organic compound sensor to detect carbon dioxide or total volatile organic compound gas information; the gas sensor 127 can be a formaldehyde sensor to detect formaldehyde gas information; the gas sensor 127 can be a bacteria sensor to detect bacteria information or fungus information; the gas sensor 127 can be a virus sensor to detect virus gas information; the gas sensor 127 can be a temperature and humidity sensor to detect gas temperature and humidity information.

The light irradiation is a photocatalyst unit of a photocatalyst 22f and an ultraviolet lamp 22g. When the photocatalyst 22f is irradiated by the ultraviolet lamp 22g, the light energy can be converted into electrical energy to decompose harmful substances in the air pollution and sterilize and sterilize to achieve a filtering and sterilization effect. The light irradiation can be a photoplasma unit of a nano-light tube 22h. The air pollution introduced by the nano-light tube 22h is irradiated to decompose oxygen molecules and water molecules in the air pollution into highly oxidizing photoplasmas, forming an ion flow that can destroy organic molecules, and volatile formaldehyde, toluene, and volatile organic gases (Volatile Organic Compounds, VOC) and other gas molecules are decomposed into water and carbon dioxide to achieve the effect of filtering and sterilization; and in some embodiments, the filter component 22 can also be combined with a decomposition unit to sterilize the air pollution by chemical means, and the decomposition unit can be a negative ion unit 22i, so that the positively charged particles contained in the introduced air pollution are attached to the negatively charged particles, so as to achieve the effect of filtering and sterilizing the introduced air pollution.
