Description

[Technical field]

[0001] The present invention relates to an indoor air cleaning system, and more particularly to an indoor air cleaning system applicable to a clean room level where the gas state in an indoor area is determined by a cleanliness standard of particle count. [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 paying attention to the quality of the gases around them in their lives, for example, carbon monoxide, carbon dioxide, volatile organic compounds (VOCs), PM2.5, nitrogen monoxide, sulfur monoxide, and other gases, as well as the fine particles contained in gases, are all exposed to the environment and can affect human health, and in severe cases, even be life-threatening. 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 move 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. In addition to outdoor air quality, indoor air conditioning conditions and pollution sources are all major factors that affect indoor air quality. It is possible to intelligently and quickly detect indoor air pollution sources in various indoor areas, effectively remove indoor air pollution, and form a clean and safe to breathe gas state, and monitor indoor air quality in real time anytime and anywhere. Of course, in indoor areas, as long as the concentration of suspended particles is strictly controlled in accordance with the "clean room" standards, the introduction, generation and retention of particles can be avoided, and the temperature and humidity can be controlled within the required range, that is, the indoor area is distinguished by its level according to the number of suspended particles in the air, and the clean room requirements of the indoor area that can be safely breathed can be achieved.

[0006] At present, the main application field of clean rooms is the industrial environment, where a low-pollution indoor space is set up in the production facility, and pollutants such as fine dust particles in the air in the space are removed to obtain a clean environment. The pollution level of airborne particles is classified according to the number of free particles with a particle diameter of ≥ 0.5 μm contained in 1 cubic meter of air, and clean rooms have particularly strict requirements for indoor temperature, humidity, and cleanliness, so they must be controlled within a certain range to meet the required process production and working environment. Traditional clean rooms used in industrial environments have the disadvantages of high cost, large equipment scale, and large power consumption, and are not suitable for ordinary homes, offices, schools, restaurants, and public places.

[0007] In addition, traditional clean rooms, which are generally used in industrial environments, are not equipped with sensors to detect air pollution in real time 24 hours a day, so they need to operate at high speeds 24 hours a day. This operation method results in a large amount of energy loss and leads to a high-noise environment, and such clean room systems are not applicable to normal indoor domestic life.

[0008] The main objective of the present invention is to detect indoor air quality in indoor spaces such as homes, offices, schools, restaurants and public places, solve the air pollution problem, make the indoor area reach the clean room requirements, and avoid the human health impact and injury caused by environmental gas hazards. Therefore, the present invention provides an indoor air cleaning system. Summary of the Invention [Problem to be solved by the invention]

[0009] The main objective of the present invention is to provide an indoor air purification system that can generate indoor air quality as clean as that of conventional clean rooms used in industrial environments. A combination of devices such as a circulating air return passage, a circulating filter, a gas exchanger, an exhaust device, and an exhaust fan is installed in the indoor area, and a smart interlocking system is formed by arranging gas detectors and smart clouds in the indoor and outdoor areas, and the gas detectors installed in the indoor and outdoor areas detect information on PM2.5 concentration / particle count, carbon dioxide (CO2) and volatile organic compounds (VOCs) in air pollution, and compare them using cloud computing. In addition, the operating speed of the circulating filter is intelligently selected and automatically adjusted to quickly purify the pollution source, realize quiet and highly efficient operation, and quickly respond to a sudden increase in pollution through the interlocking control of the devices. Therefore, the indoor air purification system of the present invention generates indoor air quality as clean as that of conventional clean rooms used in industrial environments, does not require the wearing of dustproof clothing, and is the only system currently available for general indoor life that can provide clean room-like air quality.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The following description will provide detailed descriptions of the embodiments that illustrate 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 that the description and drawings are illustrative in nature, and are not intended to limit the present invention.

[0013] 1A and 1B, the present invention is an indoor air purification system including a plurality of gas detectors a, at least one circulating air return passage C, at least one circulating filtration device 2, at least one air conditioning device 3, and a cloud computing service device 4.

[0014] The gas detectors a are provided in the indoor area A and the outdoor area B, detect air pollution information, and output the air pollution information through Internet of Things communication. A gas detection module is provided inside the gas detector a. Referring to FIG. 3A and FIG. 3B, the gas detector a may be configured in a form having an external power supply terminal, which can be directly inserted into the power supply interface in the indoor area A to start operation and detect air pollution. Alternatively, as shown in FIG. 3C, the gas detector a is in the form of a gas detection module without an external power supply terminal, directly incorporated into the device (circulation filtration device 2, air conditioner 3, gas exchange device 5, exhaust device 6, exhaust fan 7), connected to the drive control part b, receives control commands, transmits them to the drive control part b to control the power start operation of the device, and detects air pollution. The Internet of Things (IoT) communication refers to a technology for communication between a collective network connecting various devices and a support device, and between the cloud and the device. The Internet of Things communication may be wired communication for connecting and communicating with a cloud computing service device 4 via a wired line. The Internet of Things communication may be wireless communication to connect and communicate with the cloud computing service device 4 via a wireless connection. The wireless communication may be a Wi-Fi module, a Bluetooth module, a radio frequency identification module, or a near field communication module.

[0015] 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.

[0016] The circulating air return passage C is surrounded and isolated by a plurality of partition members 1C, formed on the side of the indoor area A, and equipped with a plurality of air inlets 2C and a plurality of air return ports 3C. The circulating filtering device 2 is installed in the circulating air return passage C and corresponds to the air inlets 2C. The circulating filtering device 2 includes a wind guide device 21, a filtering part 22, a gas detector a, and a drive control part b, and the gas detector a receives a control command through Internet of Things communication and transmits it to the drive control part b to control and start the operation of the wind guide device 21, and the wind guide device 21 starts under control, and the air pollution is filtered by the filtering part 22, discharged to the air inlet 2C, and guided to enter the space of the indoor area A.

[0017] The air conditioner 3 is installed in the indoor area A to adjust the temperature and humidity, and includes a gas detector a and a driving control part b. The gas detector a directly detects whether the temperature and humidity exceed the temperature and humidity set safe value, that is, the air pollution information of the temperature and humidity of the indoor area A needs to be maintained as air pollution data of temperature 25°C±3°C and humidity 50%±10%. When the gas detector a detects that the temperature and humidity set safe value is exceeded, it directly issues a control command to the driving control part b to control the start-up operation of the air conditioner 3, and adjusts the indoor area A to maintain a comfortable temperature and humidity living environment. Alternatively, the cloud computing service device 4 performs intelligent calculation based on the big data database of the air pollution data, and compares it with the temperature and humidity set safe value of the indoor area A. When the temperature and humidity set safe value of temperature 25°C±3°C and humidity 50%±10% is exceeded, the cloud computing service device 4 intelligently and selectively issues a control command. The gas detector a receives the control command via Internet of Things communication and transmits it to the drive control component b to control the start-up operation of the air conditioner 3, thereby adjusting the indoor area A to maintain a comfortable temperature and humidity living environment. The air conditioner 3 adjusts the indoor area A to maintain a temperature of 25°C±3°C and a humidity of 50%±10%.

[0018] The cloud computing service device 4 receives air pollution information of the indoor area A and the outdoor area B through Internet of Things communication, stores and forms a big data database of air pollution data, receives temperature and humidity information of gas output from the air conditioner 3, and intelligently and selectively issues a control command to the air guide device 21 of the circulation filtration device 2 based on the big data database of air pollution data and the intelligent calculation and comparison of the temperature and humidity information of gas to start and control the operation, continuously generates an internal circulation directional airflow in the indoor area A, guides the air pollution, and filters and removes it multiple times by the filtering part 22, so that the cleanliness standard of the particle number of suspended particles with a particle diameter of less than 2.5 μm in the gas state in the indoor area A reaches clean room levels 1 to 9 (ZAPClean room 1 to 9). The intelligent calculation includes artificial intelligence (AI) calculation and edge calculation.

[0019] In addition, as shown in FIG. 1B, in order to avoid the effects and injuries of carbon dioxide (CO2) on human health, at least one gas exchange device 5 can be further installed in the indoor area A to introduce gas from the outdoor area B into the indoor area A for ventilation. The gas exchange device 5 is installed in the circulating air return passage C, corresponds to the air inlet 2C, and communicates with the air inlet passage 51 to communicate with the gas in the outdoor area B. In addition, the gas exchange device 5 includes a gas detector a and a drive control part b. The gas detector a directly detects whether carbon dioxide (CO2) exceeds the carbon dioxide (CO2) set safety value, that is, the air pollution information of carbon dioxide (CO2) in the indoor area A needs to be maintained at air pollution data below 800 PPM. When the gas detector a detects that the carbon dioxide (CO2) set safety value is exceeded, it directly issues a control command to the drive control part b to control the start-up operation of the gas exchange device 5, and introduces the gas in the outdoor area B into the indoor area A for ventilation. Alternatively, the cloud computing service device 4 performs intelligent calculations based on the big data database of air pollution data, and compares it with the carbon dioxide (CO2) set safety value. When the carbon dioxide (CO2) set safety value is exceeded, the cloud computing service device 4 intelligently and selectively issues a control command. The gas detector a receives the control command through Internet of Things communication, and transmits it to the drive control part b to control the start-up operation of the gas exchange device 5, thereby introducing the gas in the outdoor area B into the indoor area A for ventilation. In addition, a valve 52 controlled by the drive control part b is provided between the air introduction passage 51 communicating with the gas exchange device 5 and the gas communication of the outdoor area B. When the gas detector a receives the control command, it transmits it to the drive control part b to control the start-up operation of the gas exchange device 5, and controls the opening of the valve 52 to connect the air introduction passage 51 to the gas in the outdoor area B, and introduce the gas in the outdoor area B into the indoor area A for ventilation.The air pollution information detected in the indoor area A and the outdoor area B is carbon dioxide (CO2) air pollution data, and the cloud computing service device 4 receives the air pollution information of the indoor area A and the outdoor area B through Internet of Things communication, and performs intelligent calculation and comparison based on the big data database of the air pollution data. In order to avoid the impact and injury of carbon dioxide (CO2) in the indoor area A on human health, it is necessary to maintain the air pollution data of carbon dioxide (CO2) in the indoor area A at less than 800 PPM. When the air pollution information of the indoor area A is higher than the air pollution information of the outdoor area B, that is, when the carbon dioxide (CO2) air pollution information of the indoor area A is higher than the air pollution data of 800 PPM and the air pollution information of the indoor area A is higher than the air pollution information of the outdoor area B, the cloud computing service device 4 intelligently and selectively issues a control command, which is transmitted to the gas detector a of the gas exchange device 5 via Internet of Things communication, and further transmitted to the drive control part b to control the start-up operation of the gas exchange device 5, so as to introduce the gas in the outdoor area B into the indoor area A for ventilation. Note that the gas exchange device 5 may be, but is not limited to, a ventilation device.

[0020] In addition, when the indoor area A is the environment of the kitchen space area A1, serious air pollution will occur relatively quickly when cooking food, and it is necessary to accelerate the discharge of air pollution to the outdoor area B in order to avoid the impact and injury to human health caused by the air pollution generated in the indoor area A. Therefore, the indoor air purification system can further include at least one exhaust device 6 when the indoor area A is the kitchen space area A1. The exhaust device 6 includes a gas detector a and a driving control part b. The gas detector a of the exhaust device 6 directly detects whether PM2.5 exceeds the PM2.5 air pollution set safety value, that is, when the PM2.5 concentration is 10 μg / m 3When gas detector a detects that the PM2.5 air pollution set safety value is exceeded, it issues a control command to drive control component b to control the start-up operation of exhaust device 6, thereby quickly discharging the air pollution in indoor area A to outdoor area B. Alternatively, cloud computing service device 4 receives air pollution information detected by multiple gas detectors a in indoor area A, performs intelligent calculations based on the big data database of air pollution data, compares the air pollution information of PM2.5 air pollution in kitchen space area A1 (concentration of PM2.5 air pollution set safety value is 10 μg / m 3 The control command is sent to the gas detector a of the exhaust device 6 via the Internet of Things communication, and then sent to the driving control component b to control the starting operation of the exhaust device 6, thereby quickly exhausting the air pollution in the indoor area A to the outdoor area B.

[0021] In addition, when the indoor area A is the bathroom / toilet space area A2 environment, high temperature and humidity and air pollution will occur immediately when taking a shower or using the toilet. In order to avoid the impact and injury to human health caused by the temperature, humidity and pollution in the indoor area A, the indoor air purification system can further include at least one exhaust fan 7 when the indoor area A is the bathroom / toilet space area A2. The exhaust fan 7 includes a gas detector a and a drive control part b. The gas detector a directly detects whether the temperature and humidity set safety values ​​and the air pollution set safety values ​​are exceeded, and the temperature and humidity set safety values ​​are maintained at a temperature of 25°C±3°C and a humidity of 50%±10%, and the air pollution set safety values ​​are maintained at a total volatile organic compound (TVOC) concentration of less than 0.56 ppm and a sulfur dioxide concentration of less than 0.075 ppm. When the gas detector a detects that the temperature and humidity set safety values ​​and the air pollution set safety values ​​are exceeded, it issues a control command to the drive control part b to control the start-up operation of the exhaust fan 7, thereby quickly exhausting the air pollution in the indoor area A to the outdoor area B and adjusting the temperature and humidity in the indoor area A. Alternatively, the cloud computing service device 4 receives the air pollution information and the temperature and humidity information detected by the multiple gas detectors a in the indoor area A, performs intelligent calculations based on the big data database of the air pollution data, compares the air pollution information and the temperature and humidity information in the bathroom and toilet space area A2, intelligently and selectively issues a control command, transmits it to the gas detector a of the exhaust fan 7 via Internet of Things communication, and further transmits it to the drive control part b to control the start-up operation of the exhaust fan 7, thereby quickly exhausting the air pollution in the indoor area A to the outdoor area B and adjusting the temperature and humidity in the indoor area A.

[0022] As can be seen from the above description, in the indoor air purification system provided by the present invention, the cloud computing service device 4 receives air pollution information of the indoor area A and the outdoor area B through Internet of Things communication, stores and forms a big data database of air pollution data, receives temperature and humidity information of the gas output from the air conditioner 3, performs intelligent calculation and comparison based on the big data database of air pollution data and the gas temperature and humidity information, and intelligently and selectively issues control commands to the air guidance device 21 of the circulation filtration device 2 to start and control its operation, continuously generating an internal circulation directional airflow in the indoor area A, and guiding the air pollution to be filtered and removed multiple times by the filtering part 22. In other words, the cloud computing service device 4 intelligently calculates the real-time particle number cleanliness of the suspended particles in the indoor area A, intelligently and selectively issues control commands and sends them to the multiple circulating filtration devices 2 to timely start and control the operation of the air guide device 21 of the circulating filtration device 2, thereby randomly adjusting the airflow volume and start-up time of the air guide device 21 according to the real-time particle number cleanliness of the suspended particles, improving the cleaning efficiency of the indoor area A, reducing the environmental noise of the indoor area A, generating an internal circulating directional airflow in the indoor area A, quickly guiding air pollution to be filtered and removed multiple times by the filtering parts 22, and making the cleanliness standard of the particle number of suspended particles with a particle diameter of less than 2.5 μm in the gas state in the indoor area A reach clean room levels 1 to 9 (ZAPClean room 1 to 9).

[0023] As shown in FIG. 13, a comparison table is created to distinguish the clean room levels formed by the cleanliness standard of the number of suspended particles with a particle diameter of less than 2.5 μm for the air pollution in indoor area A. The indoor air cleaning system provided by the present invention adjusts the gas state in indoor area A so that the number of suspended particles with a particle diameter of less than 2.5 μm formed per cubic meter is less than 1, thereby satisfying the cleanliness standard requirements of clean room level 1 (ZAP Clean room 1). The gas state in indoor area A adjusts the number of suspended particles with a particle diameter of less than 2.5 μm formed per cubic meter to less than 10, thereby satisfying the cleanliness standard requirements of clean room level 2 (ZAP Clean room 2). The gas conditions in indoor area A are adjusted so that the number of suspended particles less than 2.5 μm in diameter formed per cubic foot is less than 3, and the number of suspended particles less than 2.5 μm in diameter formed per cubic meter is less than 100, thereby satisfying the cleanliness standard requirements for cleanroom level 3 (ZAP Clean room 3). The gas conditions in indoor area A are adjusted so that the number of suspended particles less than 2.5 μm in diameter formed per cubic foot is less than 28, and the number of suspended particles less than 2.5 μm in diameter formed per cubic meter is less than 1,000, thereby satisfying the cleanliness standard requirements for cleanroom level 4 (ZAP Clean room 4). The gas conditions in indoor area A are adjusted so that the number of suspended particles less than 2.5 μm in diameter formed per cubic foot is less than 286, and the number of suspended particles less than 2.5 μm in diameter formed per cubic meter is less than 10,000, thereby satisfying the cleanliness standard requirements for cleanroom level 5 (ZAP Clean room 5). The gas conditions in indoor area A are adjusted so that the number of suspended particles less than 2.5 μm in diameter formed per cubic foot is less than 2,860, and the number of suspended particles less than 2.5 μm in diameter formed per cubic meter is less than 100,000, thereby satisfying the cleanliness standard requirements for cleanroom level 6 (ZAP Clean room 6).The gas conditions in the indoor area A are adjusted so that the number of suspended particles less than 2.5 μm in diameter formed per cubic foot is less than 28,600, and the number of suspended particles less than 2.5 μm in diameter formed per cubic meter is less than 1,000,000, to meet the cleanliness standard requirements for cleanroom level 7 (ZAP Clean room 7). The gas conditions in the indoor area A are adjusted so that the number of suspended particles less than 2.5 μm in diameter formed per cubic foot is less than 77,200, and the number of suspended particles less than 2.5 μm in diameter formed per cubic meter is less than 2,720,000, to meet the cleanliness standard requirements for cleanroom level 8 (ZAP Clean room 8). The gas conditions in indoor area A are adjusted so that the number of suspended particulate particles less than 2.5 μm in diameter formed per cubic foot is less than 154,300, and the number of suspended particulate particles less than 2.5 μm in diameter formed per cubic meter is less than 5,440,000, thereby meeting the cleanliness standard requirements for clean rooms level 9 (ZAP Clean room 9).

[0024] In order to understand the specific implementation of the indoor air cleaning system provided by the present invention, the structure of the gas detection module of the gas detector a of the present invention will be described in detail below. With reference to Figs. 3A to 11, the gas detection module includes a control circuit board 11, a gas detection body 12, a microprocessor 13, and a communication device 14. The gas detection body 12, the microprocessor 13, and the communication device 14 are packaged and integrally formed in the control circuit board 11 and are electrically connected. The microprocessor 13 and the communication device 14 are installed on the control circuit board 11, and the microprocessor 13 controls the drive signal of the gas detection body 12 to start the detection operation, so that the gas detection body 12 detects air pollution and outputs the detection information, which is processed and output by the microprocessor 13, provided to the communication device 14, communicated to the outside via Internet of Things (IoT) communication, and transmitted to the cloud computing service device 4.

[0025] 4A to 9A, the gas detection main body 12 includes a base 121, a piezoelectric actuator 122, a drive circuit board 123, a laser component 124, a particulate sensor 125, and an outer lid 126. The base 121 has a first surface 1211, a second surface 1212, a laser installation area 1213, an intake groove 1214, an air-conducting component mounting area 1215, and an exhaust groove 1216. The first surface 1211 and the second surface 1212 are two surfaces that are installed opposite 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 that has an intake frame opening 1261a and an exhaust frame opening 1261b. The intake groove 1214 is recessed from the second surface 1212 and is adjacent to the laser installation area 1213. The intake groove 1214 is provided with an intake vent 1214a that communicates with the outside of the base 121 and corresponds to the intake frame port 1261a of the outer lid 126, and both side walls of the intake groove 1214 are penetrated by light transmission windows 1214b and communicates with the laser installation area 1213. Thus, the first surface 1211 of the base 121 is covered with the outer lid 126, and the second surface 1212 is covered with the drive circuit board 123, thereby defining an intake path by the intake groove 1214.

[0026] The air-conducting component mounting area 1215 is recessed from the second surface 1212, communicates with the intake groove 1214, has a ventilation hole 1215a penetrating through the bottom surface, and has positioning protrusions 1215b at each of the four corners of the air-conducting component mounting area 1215. The exhaust groove 1216 is provided with an exhaust vent 1216a installed corresponding to the exhaust frame opening 1261b of the outer lid 126. The exhaust groove 1216 includes a first section 1216b recessed in the vertical projection area of ​​the first surface 1211 onto the air-conducting component mounting area 1215, and a second section 1216c hollowed out from the first surface 1211 toward the second surface 1212 in an area extending from the vertical projection area of ​​the air-conducting component mounting area 1215, the first section 1216b being connected to the second section 1216c to form a step, and the first section 1216b of the exhaust groove 1216 communicating with the ventilation hole 1215a of the air-conducting component mounting area 1215, and the second section 1216c of the exhaust groove 1216 communicating with the exhaust vent 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 drive circuit board 123, the exhaust groove 1216 and the drive circuit board 123 together define an exhaust path.

[0027] The laser component 124 and the particle sensor 125 are both installed on the drive circuit board 123 and located in the base 121. In order to clearly explain the positions of the laser component 124, the particle sensor 125, and the base 121, the drive circuit board 123 is intentionally omitted. The laser component 124 is accommodated in the laser installation area 1213 of the base 121, and the particle sensor 125 is accommodated in the intake groove 1214 of the base 121 and aligned with the laser component 124. In addition, the laser component 124 corresponds to the light transmission window 1214b through which the laser light emitted by the laser component 124 passes, thereby irradiating the laser light to the intake groove 1214. The beam path emitted by the laser component 124 passes through the light transmission window 1214b and is perpendicular to the intake groove 1214. The beam emitted by the laser component 124 passes through the light-transmitting window 1214b into the intake groove 1214, and irradiates the gas in the intake groove 1214. When the beam comes into contact with the gas, it scatters to generate a projected spot, and the particle sensor 125 is located at a position perpendicular to the gas sensor, and receives and calculates the scattered projected spot to obtain gas detection data.

[0028] The piezoelectric actuator 122 is accommodated in a square air-conducting component mounting area 1215 of the base 121. The air-conducting component mounting area 1215 is also connected to an intake groove 1214. When the piezoelectric actuator 122 is activated, the gas in the intake groove 1214 is sucked into the piezoelectric actuator 122, and the gas passes through a vent hole 1215a of the air-conducting component mounting area 1215 and enters the exhaust groove 1216. The drive circuit board 123 covers the second surface 1212 of the base 121. The laser component 124 is installed and electrically connected to the drive circuit board 123. The particulate sensor 125 is also installed and electrically connected to the drive circuit board 123. When the outer lid 126 covers the base 121 , the intake frame opening 1261 a corresponds to the intake vent opening 1214 a of the base 121 , and the exhaust frame opening 1261 b corresponds to the exhaust vent opening 1216 a of the base 121 .

[0029] The piezoelectric actuator 122 includes a gas orifice plate 1221, a chamber housing 1222, an actuator 1223, an insulating housing 1224, and a conductive housing 1225. The gas orifice plate 1221 is made of a flexible material and has a suspension plate 1221a and a hollow hole 1221b, the suspension plate 1221a 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 1215, and the hollow hole 1221b penetrates the center of the suspension plate 1221a to allow gas to flow through. In a preferred embodiment of the present invention, the shape of the suspension plate 1221a may be any of a square, a circle, an ellipse, a triangle, and a polygon.

[0030] The chamber housing 1222 is stacked on the gas orifice plate 1221, and its appearance corresponds to the gas orifice plate 1221. The actuator 1223 is stacked on the chamber housing 1222, and defines a resonant chamber 1226 between the gas orifice plate 1221 and the chamber housing 1222. The insulating housing 1224 is stacked on the actuator 1223, and its appearance is similar to the chamber housing 1222. The conductive housing 1225 is stacked on the insulating housing 1224, and its appearance is similar to the insulating housing 1224. The conductive housing 1225 has a conductive pin 1225a and a conductive electrode 1225b, where the conductive pin 1225a extends outward from the outer edge of the conductive housing 1225, and the conductive electrode 1225b extends inward from the inner edge of the conductive housing 1225. The actuator 1223 further includes a piezoelectric carrier plate 1223a, a resonance adjustment plate 1223b, and a piezoelectric plate 1223c. The piezoelectric carrier plate 1223a is stacked on the chamber housing 1222. The resonance adjustment plate 1223b is stacked on the piezoelectric carrier plate 1223a. The piezoelectric plate 1223c is stacked on the resonance adjustment plate 1223b. The resonance adjustment plate 1223b and the piezoelectric plate 1223c are housed in an insulating housing 1224. The conductive electrode 1225b of the conductive housing 1225 is electrically connected to the piezoelectric plate 1223c. In a preferred embodiment of the present invention, the piezoelectric carrier plate 1223a and the resonance adjustment plate 1223b are both made of conductive materials. The piezoelectric carrier 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) on the driving circuit board 123 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 1223d, the piezoelectric carrier plate 1223a, the resonance adjustment plate 1223b, the piezoelectric plate 1223c, the conductive electrode 1225b, the conductive housing 1225, and the conductive pin 1225a, and the insulating housing 1224 can cut off the conductive housing 1225 and the actuator 1223 to prevent a short circuit phenomenon, and 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 carrier plate 1223a and the resonance adjustment plate 1223b to generate a reciprocating bending vibration.

[0031] More specifically, the resonance adjusting plate 1223b is located between the piezoelectric plate 1223c and the piezoelectric carrier plate 1223a as a buffer between them, and can adjust the vibration frequency of the piezoelectric carrier plate 1223a. Basically, the thickness of the resonance adjusting 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 resonance adjusting plate 1223b.

[0032] 7A, 7B, 8A, 8B, and 9A, the gas orifice plate 1221, the chamber housing 1222, the actuator 1223, the insulating housing 1224, and the conductive housing 1225 are stacked and positioned in order in the air-conducting component mounting area 1215, so that the piezoelectric actuator 122 is positioned in the air-conducting component mounting area 1215, and the piezoelectric actuator 122 defines a gap 1221c for gas flow between the suspension plate 1221a and the inner edge of the air-conducting component mounting area 1215. An airflow chamber 1227 is formed between the gas orifice plate 1221 and the bottom surface of the air-conducting component mounting area 1215. The airflow chamber 1227 is connected to a resonant chamber 1226 between the actuator 1223, the chamber housing 1222, and the gas orifice plate 1221 via a hollow hole 1221b in the gas orifice plate 1221. By making the vibration frequency of the gas in the resonant chamber 1226 the same as the vibration frequency of the suspension plate 1221a, the resonant chamber 1226 and the suspension plate 1221a generate a Helmholtz resonance effect, thereby increasing the gas transport efficiency. When the piezoelectric plate 1223c moves away from the bottom surface of the air-conducting component mounting area 1215, the piezoelectric plate 1223c moves the suspension plate 1221a of the gas orifice plate 1221 away from the bottom surface of the air-conducting component mounting 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 piezoelectric actuator 122 is sucked in and flows in through the gap 1221c, passes through the hollow hole 1221b, and enters the resonating chamber 1226, increasing the air pressure in the resonating chamber 1226 and generating a pressure gradient. When the piezoelectric plate 1223c moves the suspension plate 1221a of the gas orifice plate 1221 to the bottom surface of the air-conducting component mounting area 1215, the gas in the resonating chamber 1226 quickly flows out through the hollow hole 1221b, squeezing out the gas in the airflow chamber 1227, 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 1215a of the air-conducting component mounting area 1215.

[0033] 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 resonating chamber 1226 after exhaust becomes lower than the equilibrium air pressure, the gas is guided back into the resonating chamber 1226. In this way, the vibration frequency of the gas in the resonating 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 gas transport. All the gas enters from the intake frame port 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 driving of the piezoelectric actuator 122, so that the external gas is rapidly introduced and stably circulated, passing above the particle sensor 125. At this time, the beam emitted by the laser component 124 passes through the light transmission window 1214b and enters the intake groove 1214, and the intake groove 1214 passes above the particle sensor 125. When the beam of the particle sensor 125 is irradiated on the suspended particles in the gas, a scattering phenomenon and a projection spot are generated, and the particle sensor 125 receives the projection spot caused by scattering and performs calculations to obtain related information such as the particle diameter and concentration of the suspended particles contained in the gas. The gas above the particle sensor 125 is also introduced into the ventilation hole 1215a of the air-conducting component mounting area 1215 by the continuous driving of the piezoelectric actuator 122, and enters the exhaust groove 1216. Finally, after the gas enters the exhaust groove 1216, the piezoelectric 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 discharged to the outside through the exhaust vent 1216a and the exhaust frame port 1261b.

[0034] The gas detector a 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, and ozone. Therefore, the gas detector a of the present invention further includes a gas sensor 127, which is positioned and installed on the driving circuit board 123, electrically connected, and accommodated in the exhaust groove 1216 to detect the characteristics of the introduced gas. The gas sensor 127 may be a volatile organic compound sensor that detects gas information of carbon dioxide or total volatile organic compounds. The gas sensor 127 may be a formaldehyde sensor that detects gas information of formaldehyde. The gas sensor 127 may be a bacteria sensor that detects bacteria information or fungus information.

The light irradiation is a photocatalyst unit including a photocatalyst 22f and an ultraviolet lamp 22g. When the photocatalyst 22f is irradiated by the ultraviolet lamp 22g, the light energy is converted into electrical energy, and harmful substances in air pollution are decomposed and disinfected, thereby achieving the effects of filtration and sterilization.The light irradiation may be an optical plasma unit including an optical nanotube 22h, and the optical nanotube 22h irradiates the introduced air pollution to decompose the oxygen molecules and water molecules in the air pollution 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 compounds (VOCs) contained in the air pollution into water and carbon dioxide, thereby achieving the effect of filtering and sterilizing.
