Description

Technical Field

[0001] The present invention relates to an indoor air purification system, and particularly to a detection and disconnection prevention mechanism for an indoor air purification system.

Background Art

[0002] Suspended particulate matter refers to individual particles or droplets contained in gas. Since its particle size is extremely fine, it can pass through the nasal hairs in the nasal cavity and enter the human lungs, easily causing lung inflammation, asthma or cardiovascular diseases. When other pollutants adhere to the suspended particulate matter, the harm to the respiratory system also deteriorates. In recent years, the problem of gas pollution has become increasingly serious. In particular, the concentration data of fine suspended particles (such as PM2.5) are often too high, and the importance of monitoring the concentration of gas suspended particles is increasing. However, the gas flow is unstable due to the wind direction and wind volume, and most of the current gas quality monitoring stations for detecting suspended particulate matter are fixed-point type, so the current concentration of surrounding suspended particulate matter cannot be confirmed.

[0003] In addition, modern people are paying more and more attention to the quality of the gas around them. For example, gases such as carbon monoxide, carbon dioxide, volatile organic compounds (VOC), PM2.5, nitric oxide, sulfur monoxide, and thus the particles contained in the gas are exposed to the environment, affecting human health and in some cases threatening life. Therefore, the quality of environmental gas has attracted the attention of various countries. A method for detecting gas quality to avoid areas with poor gas quality and stay away from those areas has become an important issue at present.

[0004] As a method for confirming the gas quality, it is considered to detect the surrounding environmental gas using a gas sensor. In addition, since it can immediately provide detection information and warn people in the environment to take immediate prevention or evacuation to prevent the impact and injury on human health caused by gas danger in the environment, detecting the surrounding environment with a gas sensor is a very good method.

[0005] Furthermore, it is difficult to grasp the quality of indoor air. In addition to the quality of outdoor air, the indoor air conditioning situation and pollution sources are also the main factors affecting indoor air quality. Therefore, it has become the focus of current research and development to intelligently and quickly detect indoor air pollution sources in various areas of the room, effectively remove indoor air pollution to form a clean and safe breathing gas state, and be able to monitor the quality of indoor air immediately at any time and anywhere. Of course, in the indoor area, strictly manage the concentration of floating particles according to the standards of a "Clean Room", avoid the introduction, generation and retention of particles as much as possible, and manage the temperature and humidity within the required range. That is, if the classes can be distinguished by the number of floating particles in the air in the indoor area, the clean room requirements for a safely breathable indoor area can be met.

[0006] In the air pollution detection of the currently provided indoor air purification system, a gas detector is used to detect and transmit air pollution information. Furthermore, through IoT communication, a cloud computing service device receives the air pollution information of the outdoor area and the indoor area, stores it to form a big database of air pollution data, and intelligently calculates and compares based on the big database of air pollution data to intelligently select and issue a control command, which is sent to the blower of the gas filtration device to activate an adjustment operation. As a result, an internal circulation air flow continuously occurs in the indoor area, and the air pollution is guided multiple times to pass through the filter element for filtration and removal, so that the gas state in the indoor area can reach the clean room class based on the cleanliness standard of the number of floating particles. However, the air pollution information output by the air pollution detection is transmitted through IoT communication. If the IoT communication for transmission is disconnected, it may affect the guidance of the gas filtration device and the filtration operation of air pollution. Measures for the detection mechanism to prevent the disconnection of IoT communication have become the main issue of the present invention.

Summary of the Invention

[0007] The main object of the present invention is to provide a detection disconnection prevention mechanism for an indoor air purification system. A gas detector is provided for each of the gas filtration devices in the room, whereby air pollution is detected, air pollution information is transmitted, a control command is received, and it is electrically connected to the drive control element of the gas filtration device. The drive control element controls the startup and operation of the gas filtration device, and the transmission of the air pollution information output from the gas detector is realized by IoT communication. Here, IoT communication may be realized by selecting a communication mechanism capable of performing transmission by two methods of wired communication and wireless communication. Under the monitoring mechanism of the actual handshake communication protocol of wired communication and wireless communication, by spontaneously selecting one of the wired communication capable of performing transmission communication or the wireless communication capable of performing transmission communication, the air pollution information output by air pollution detection is transmitted to the cloud computing service device. Further, the cloud computing service device generates a control command and feeds it back to the gas detector, and transmits it to the electrically connected drive control element. The drive control element controls the startup and operation of the gas filtration device, and realizes the detection disconnection prevention mechanism measures to be solved by IoT communication. Also, when both the wired communication and the wireless communication of the air pollution information detected and output by the gas detector are disconnected, the gas detector can spontaneously calculate and compare the air pollution information, and spontaneously transmit a control command to the drive control element of the gas filtration device to control the startup and operation of the blower. Thus, the blower is started under control, and air pollution is guided so that air pollution passes through the filter element and is filtered, and the air pollution gas state in the indoor area approaches zero and meets the requirements of the clean room class.

[0008] To achieve the above object, the present invention provides a detection and disconnection prevention mechanism for an indoor air purification system. The detection and disconnection prevention mechanism for the indoor air purification system includes at least one gas filtration device and a cloud computing service device. The at least one gas filtration device is provided in the indoor area and includes a blower, a filter element, a gas detector, and a drive control element. The gas detector detects air pollution and outputs the air pollution information by IoT communication. The gas detector receives a control command by the IoT communication and transmits it to the drive control element to control the startup and operation of the blower. The blower is activated upon receiving control and guides the air pollution so that the air pollution passes through the filter element and is filtered. The cloud computing service device receives the air pollution information detected and output by the gas detector by the IoT communication, stores it to form a big database of air pollution data, and intelligently selects and issues the control command by performing intelligent calculation and comparison based on the big database of the air pollution data. The gas detector of the gas filtration device receives the control command and transmits it to the drive control element to control the startup and operation of the blower. When a disconnection situation occurs in the IoT communication with the Handshake communication protocol, the air pollution information detected and output by the gas detector automatically calculates and compares the air pollution information, transmits the control command to the drive control element to control the startup and operation of the blower, and the blower is activated upon receiving control and guides the air pollution so that the air pollution passes through the filter element and is filtered. As a result, the air pollution gas state in the indoor area approaches zero and meets the requirements of the clean room class.

Embodiments for Carrying Out the Invention

[0010] Hereinafter, embodiments showing the features and advantages of the present invention will be described in detail. It should be understood that there are various changes in different aspects of the present invention, all of which are included in the scope of the present invention, and the description and drawings thereof are essentially for explanatory purposes and do not limit the present invention.

[0011] FIG. 1A and FIG. 1B are schematic diagrams of the usage states in the indoor area of the indoor air purification system according to the present invention. The present invention provides a detection disconnection prevention mechanism for an indoor air purification system in order to achieve the detection disconnection prevention mechanism measures to be solved for preventing the disconnection situation of the IoT communication of the indoor air purification system.

[0012] The detection and disconnection prevention mechanism for the indoor air purification system includes at least one gas filtration device D provided in the indoor area A. The gas filtration device D includes a blower D1, a filter element D2, a gas detector 1, and a drive control element D3. Here, the gas detector 1 detects air pollution and outputs air pollution information through IoT communication. The gas detector 1 receives a control command through the IoT communication, transmits it to the drive control element D3, and controls the startup and operation of the blower D1. The blower D1 is activated upon receiving control and guides the air pollution so that the air pollution passes through the filter element D2 and is filtered. Note that 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.

[0013] The cloud computing service device 2 receives the air pollution information detected and output by the gas detector 1 through IoT communication, stores it, forms a big database of air pollution data, and intelligently calculates and compares based on the big database of air pollution data to intelligently select a control command and transmit it to the gas detector 1 of the gas filtration device. The gas detector 1 receives this control command, transmits it to the drive control element D3, and controls the startup and operation of the blower D1. The blower D1 is activated upon receiving control and guides the air pollution so that the air pollution passes through the filter element D2 and is filtered. As a result, the state of the air pollution gas in the indoor area A approaches zero and meets the class requirements of the clean room. Note that the Internet of Things (IoT) communication refers to a collective network connected to various devices, as well as technologies that support communication between devices and the cloud and between devices.

[0014] The IoT communication is a wired communication for connecting and communicating with the cloud computing service device 2 via a wired line. The cloud computing service device 2 receives air pollution information, performs intelligent calculations, makes comparisons, intelligently selects a control command, and sends it to the gas detector 1. The gas detector 1 receives this control command and sends it to the drive control element D3. The drive control element D3 controls the startup and operation of the blower D1 of the gas filtration device D. The blower D1 is activated upon receiving the control and guides the air pollution so that the air pollution passes through the filter element D2 and is filtered. As a result, the state of the air pollution gas in the indoor area A approaches zero and meets the class requirements of the clean room.

[0015] The IoT communication is a wireless communication for connecting and communicating with the cloud computing service device 2 wirelessly. The cloud computing service device 2 receives air pollution information, performs intelligent calculations, makes comparisons, intelligently selects a control command, and sends it to the gas detector 1. The gas detector 1 receives this control command and sends it to the drive control element D3. The drive control element D3 controls the startup and operation of the blower D1 of the gas filtration device D. The blower D1 is activated upon receiving the control and guides the air pollution so that the air pollution passes through the filter element D2 and is filtered. As a result, the state of the air pollution gas in the indoor area A approaches zero and meets the class requirements of the clean room. This wireless communication may be one of a Wi-Fi module, a Bluetooth module, a radio frequency identification module, and a near-field wireless communication module.

[0016] Of course, in the case where the IoT communication has a mechanism that can determine whether there is a disconnection situation in the handshake communication protocol of wired communication or wireless communication, one of the wired communication and wireless communication capable of executing transmission can be selected to control the startup of the mechanism. The cloud computing service device 2 controls the startup of the mechanism by controlling one of the wired communication and wireless communication capable of executing transmission, receives air pollution information, performs intelligent calculation and comparison. The gas detector 1 receives this control command and sends it to the drive control element D3. The drive control element D3 controls the startup and operation of the blower D1. The blower D1 is started upon receiving the control, guides the air pollution so that the air pollution passes through the filter element D2 and is filtered, whereby the state of the air pollution gas in the indoor area A approaches zero and meets the class requirements of the clean room. Also, in the case where the wired communication and wireless communication of the IoT communication have the handshake communication protocol disconnected, the air pollution information detected and output by the gas detector 1 automatically calculates and compares the air pollution information, and automatically sends a control command to the drive control element D3 to control the startup and operation of the blower D1. The blower D1 is started upon receiving the control, guides the air pollution so that the air pollution passes through the filter element D2 and is filtered, whereby the state of the air pollution gas in the indoor area A approaches zero and meets the class requirements of the clean room.

[0017] In addition, the gas filtration device D may be provided in the indoor area A in a built-in or plug-in manner. When the gas filtration device D is provided in the indoor area A in a built-in manner (see FIGS. 1A and 1B), at least one circulation and return air passage C, a plurality of air inlets C2, and a plurality of return air outlets C3 are provided in the indoor area A. The circulation and return air passage C is formed on the side of the indoor area A so as to be taken in and isolated by a plurality of spacers C1. The gas filtration device D is provided in the circulation and return air passage C of the indoor area A and corresponds to the air inlet C2.

[0018] In an embodiment of the present invention, as shown in FIGS. 1A and 1B, the gas filtration device D may be a gas exchange device 1D. The gas exchange device 1D communicates with the gas in the outdoor area B by communicating with the intake passage 1D1. The gas detector 1 of the gas exchange device 1D receives a control command through IoT communication, and further transmits this control command to the drive control element D3 to control the startup and operation of the blower D1, thereby introducing the gas in the outdoor area B into the indoor area A to perform ventilation. As shown in FIGS. 1A and 1B, a plurality of gas detectors a are further provided in the indoor area A and the outdoor area B to detect air pollution and output air pollution information. A gas detection module is provided inside the gas detector a. As shown in FIGS. 3A and 3B, it may be a gas detector a configured in a form containing an external power supply terminal. The detection operation of air pollution can be activated simply by directly inserting the external power supply terminal into the power interface in the indoor area A or the power interface arranged in the outdoor area B. The gas detector a has the same function as the gas detector 1 shown in FIG. 3C, which does not include an external power supply terminal and is configured in the form of a gas detection module, but is different in the following points. That is, the gas detector 1 is provided in the gas filtration device D as it is in the form of a gas detection module to detect air pollution, is electrically connected to the drive control element D3, receives a control command, and further transmits this control command to the drive control element D3 to control the startup and operation of the blower D1 of the gas exchange device 1D. Note that the gas exchange device 1D may be an air exchanger.

[0019] In addition, the gas detector a outputs air pollution information through IoT communication. The cloud computing service device 2 receives the air pollution information of the indoor area A and the outdoor area B, stores it, forms a big database of air pollution data, and performs intelligent calculation and comparison on the air pollution information of the indoor area A and the outdoor area B. When the air pollution information of the indoor area A is higher than that of the outdoor area B, the cloud computing service device 2 issues a control command and sends it to the gas detector a through IoT communication. The gas detector a receives the control command and sends it to the drive control element D3 to control the startup and operation of the blower D1 of the gas exchange device 1D, thereby introducing the gas in the outdoor area B into the indoor area A to perform ventilation. Here, the air pollution information of the outdoor area B and the indoor area A is the air pollution data of carbon dioxide (CO 2 ). The air pollution information of carbon dioxide (CO 2 ) detected by the gas detector 1 must be maintained at a safety value air pollution data of less than 800 PPM. When the safety value air pollution data is exceeded, the gas exchange device 1D introduces the gas in the outdoor area B into the indoor area A to perform ventilation. In addition, a valve 1D2 controlled by the drive control element D3 is provided for the gas communication between the intake passage 1D1 and the outdoor area B. When the gas detector 1 receives a control command, it sends it to the drive control element D3 to control the startup and operation of the blower D1 of the gas exchange device 1D, and at the same time controls the opening of the valve 1D2, thereby enabling the gas in the intake passage 1D1 to communicate with the outdoor area B, and the gas in the outdoor area B is introduced into the indoor area A to perform ventilation.

[0021] The gas filtration device D may be an air conditioner 3D provided in the indoor area A for adjusting temperature and humidity. The gas detector 1 receives a control command through IoT communication, transmits it to the drive control element D3, and controls the startup and operation of the air conditioner 3D. The gas detector 1 transmits the gas temperature and humidity information in the indoor area A to the cloud computing service device 2 externally. The cloud computing service device 2 receives the gas temperature and humidity information and forms a big database of air pollution data. Note that the adjustment of temperature and humidity refers to maintaining the temperature in the indoor area A at 25°C ± 3°C and the humidity at 50% ± 10%.

[0022] The gas filtration device D may be a negative pressure exhaust fan 4D. As shown in FIGS. 1B and 1C, the negative pressure exhaust fan 4D is provided at the position of the kitchen unit A1 in the indoor area A. The negative pressure exhaust fan 4D is provided with an intake passage 4D1 communicating with the outdoor area B.

[0023] The gas filtration device D may be a smoke exhaust device 5D. As shown in FIGS. 1B and 1C, the smoke exhaust device 5D is provided at the position of the kitchen unit A1 in the indoor area A and is fitted into the circulation return air passage. The smoke exhaust device 5D is provided with an intake passage 5D1 communicating with the outdoor area B. The gas detector 1 transmits air pollution information to the cloud computing service device 2 externally.

The gas detector 1 receives a control command through IoT communication, transmits it to the drive control element D3 to control the startup and operation of the blower D1 of the smoke exhaust device 5D, guides the air pollution so that the air pollution passes through the filter element D2 and is filtered, and quickly discharges the air pollution in the indoor area A to the outdoor area B.

[0024] The gas filtration device D may be the toilet exhaust fan 6D. As shown in FIG. 1B, the toilet exhaust fan 6D is provided at the position of the toilet unit A2 in the indoor area A. The toilet exhaust fan 6D is provided with an intake passage 6D1 communicating with the outdoor area B. The gas detector 1 transmits air pollution information to the cloud computing service device 2 externally.

At the same time, the gas detector 1 of the toilet exhaust fan 6D receives the control command transmitted from the cloud computing service device 2 through IoT communication, transmits it to the drive control element D3 to control the startup and operation of the toilet exhaust fan 6D, thereby implementing temperature and humidity adjustment in the indoor area A. Note that the temperature and humidity adjustment refers to maintaining the temperature in the indoor area A at 25°C ± 3°C and the humidity at 50% ± 10%.

[0025] As can be seen from the above, the present invention provides a detection disconnection prevention mechanism for an indoor air purification system. In a specific implementation, a gas detector 1 is provided for each of the gas filtration devices D in the room. Thereby, air pollution is detected, air pollution information is transmitted, a control command is received, and it is electrically connected to the drive control element D3 of the gas filtration device D. The drive control element D3 controls the startup and operation of the gas filtration device D, and the transmission of the air pollution information output from the gas detector 1 is realized by IoT communication. Here, the IoT communication may be realized by selecting a communication mechanism capable of performing transmission by two methods of wired communication and wireless communication. Under the monitoring mechanism of the actual handshake communication protocol of wired communication and wireless communication, by spontaneously selecting one of the wired communication capable of performing transmission communication or the wireless communication capable of performing transmission communication, the air pollution information output by air pollution detection is transmitted to the cloud computing service device 2. Further, the cloud computing service device 2 generates a control command, feeds it back to the gas detector 1, and transmits it to the electrically connected drive control element D3. The drive control element D3 controls the startup and operation of the gas filtration device D, and realizes the detection disconnection prevention mechanism measures that the IoT communication attempts to solve. Also, when both the wired communication and the wireless communication of the air pollution information detected and output by the gas detector 1 are disconnected, the gas detector 1 spontaneously calculates and compares the air pollution information, and spontaneously transmits a control command to the drive control element D3 of the gas filtration device D to control the startup and operation of the blower D1. Thereby, the blower D1 is started under control, guides the air pollution so that the air pollution passes through the filter element D2 and is filtered, the air pollution gas state in the indoor area A approaches zero, and the requirements of the clean room class are satisfied.

[0026] In addition, the detection and disconnection prevention mechanism for the indoor air purification system according to the present invention receives air pollution information in the indoor area A and the outdoor area B through IoT communication by the cloud computing service device 2, stores it to form a big database of air pollution data, receives the gas temperature and humidity information output from the air conditioner 3D, and performs intelligent calculation and comparison based on the big database of the air pollution data and the gas temperature and humidity information, thereby intelligently selecting a control command and transmitting it to the blower D1 of the gas filtration device D to activate a control operation. As a result, an internal circulation air flow is continuously generated in the indoor area A, and air pollution is guided to pass through the filter element D2 multiple times and removed. That is, the cloud computing service device 2 calculates the particle number cleanliness of the immediate suspended particles in the indoor area A through intelligent calculation, intelligently selects a control command and transmits it to a plurality of gas filtration devices D, and controls the activation of the blower D1 of the gas filtration device D in a timely manner. Thereby, based on the particle number cleanliness of the immediate suspended particles, the air volume, start time, and cycle of the blower D1 are immediately adjusted, the cleaning efficiency of the indoor area A is improved, the environmental noise in the indoor area A is reduced, an internal circulation air flow is generated in the indoor area A, and air pollution is quickly guided to pass through the filter element D2 multiple times for filtration and removal, meeting the particle number cleanliness standard that the particle size of the suspended particles in the gas state in the indoor area A is less than 2.5 μm, and can reach the clean room 1-9 (ZAP Clean room 1-9) class.

[0027] As shown in Fig. 13, a clean room class discrimination comparison table is prepared based on the cleanliness standard of the number of particles with a particle size of less than 2.5 μm, which is required for air pollution in the indoor area A. By the detection and cut-off prevention mechanism for the indoor air purification system provided by the present invention, the gas state in the indoor area A is such that the number of particles with a particle size of less than 2.5 μm formed per cubic meter is less than 1, meeting the cleanliness standard requirements of Class 1 clean room (ZAP Clean room 1).

[0028] In the specific implementation of the detection and cut-off prevention mechanism for the indoor air purification system provided by the present invention, the gas detector 1 and the gas detector a have the same gas detection module in function, and only differ in appearance. Hereinafter, the structure of the gas detection modules of the gas detector 1 and the gas detector a will be described in detail.

[0029] As shown in FIGS. 3A to 11, the gas detector 1 includes 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 to be integrally formed on the control circuit board 11 and are electrically connected to each other. Here, the control circuit board 11 is electrically connected to drive the drive control element D3. The microprocessor 13 and the communicator 14 are provided on the control circuit board 11. The microprocessor 13 controls the drive signal of the gas detection body 12 to start the detection operation. In this way, the gas detection body 12 detects air pollution and outputs detection information, and the microprocessor 13 receives, calculates, and processes it, then transmits it to the communicator 14 and further transmits it to the cloud computing service device 2 via IoT (Internet of Things) communication externally.

[0030] As shown in FIGS. 4A to 9A, the gas detection main body 12 includes a base 121, a piezoelectric actuator 122, a drive circuit board 123, a laser assembly 124, a particulate sensor 125, and an outer lid 126. The base 121 has a first surface 1211, a second surface 1212, a laser placement area 1213, an intake groove 1214, an air guide assembly placement area 1215, and an exhaust groove 1216. The first surface 1211 and the second surface 1212 are two surfaces provided opposite to each other. The laser placement area 1213 is formed by punching out from the first surface 1211 toward the second surface 1212. Further, the outer lid 126 covers the base 121 and has a side plate 1261. The side plate 1261 has an intake frame opening 1261a and an exhaust frame opening 1261b. The intake groove 1214 is formed by recessing from the second surface 1212 and is close to the laser placement area 1213. An intake port 1214a is provided in the intake groove 1214, which communicates with the outside of the base 121 and corresponds to the intake frame opening 1261a of the outer lid 126. Light transmission windows 1214b penetrate through both side walls of the intake groove 1214 and communicate with the laser placement area 1213. Therefore, the first surface 1211 of the base 121 is covered by the outer lid 126, and the second surface 1212 is covered by the drive circuit board 123, whereby the intake groove 1214 defines an intake path.

[0031] The air guiding assembly arrangement area 1215 is formed with the second surface 1212 being recessed, communicates with the intake groove 1214, and has vent holes 1215a penetrating through the bottom surface. Positioning blocks 1215b are respectively provided at the four corners of the air guiding assembly arrangement area 1215. An exhaust port 1216a is provided in the exhaust groove 1216. The exhaust port 1216a is provided corresponding to the exhaust frame opening 1261b of the outer cover 126. The exhaust groove 1216 includes a first section 1216b formed with the first surface 1211 being recessed with respect to the vertical projection area of the air guiding assembly arrangement area 1215, an area extending from the vertical projection area of the air guiding assembly arrangement area 1215, and a second section 1216c formed by cutting through from the first surface 1211 to the second surface 1212. The first section 1216b and the second section 1216c are connected so that a step is formed. The first section 1216b of the exhaust groove 1216 communicates with the vent holes 1215a of the air guiding assembly arrangement area 1215, and the second section 1216c of the exhaust groove 1216 communicates with the exhaust port 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 jointly define an exhaust path.

[0032] The above-mentioned laser assembly 124 and the particulate sensor 125 are both provided on the drive circuit board 123 and are located within the base 121. To clearly illustrate the positions of the laser assembly 124 and the particulate sensor 125 and the base 121, the drive circuit board 123 is omitted. The laser assembly 124 is housed within the laser placement region 1213 of the base 121, and the particulate sensor 125 is housed within the intake groove 1214 of the base 121, aligning with the laser assembly 124. Also, the laser assembly 124 corresponds to the light transmission window 1214b. The light transmission window 1214b is for the laser light from the laser assembly 124 to pass through and irradiate the intake groove 1214. The path of the light beam from the laser assembly 124 passes through the light transmission window 1214b and is orthogonal to the intake groove 1214. The light beam from the laser assembly 124 passes through the light transmission window 1214b and enters the intake groove 1214. The detection data in the gas within the intake groove 1214 is irradiated. When the light beam contacts the gas, it scatters to generate a projected light spot, and thereby, the particulate sensor 125 is positioned in its orthogonal direction to receive and calculate the projected light spot due to scattering, obtaining the detection data of the gas.

[0033] The piezoelectric actuator 122 is housed within the square air-conducting assembly placement region 1215 of the base 121. Also, the air-conducting assembly placement region 1215 communicates with the intake groove 1214. When the piezoelectric actuator 122 operates, the gas within the intake groove 1214 is introduced into the piezoelectric actuator 122, and the gas passes through the vent hole 1215a of the air-conducting assembly placement region 1215 and enters the exhaust groove 1216. The drive circuit board 123 covers the second surface 1212 of the base 121. The laser assembly 124 is provided on and electrically connected to the drive circuit board 123. The particulate sensor 125 is also provided on and electrically connected to the drive circuit board 123. When the outer lid 126 covers the base 121, the intake frame opening 1261a corresponds to the intake port 1214a of the base 121, and the exhaust frame opening 1261b corresponds to the exhaust port 1216a of the base 121.

[0034] The piezoelectric actuator 122 includes a jet hole sheet 1221, a cavity frame 1222, an actuator body 1223, an insulating frame 1224, and a conductive frame 1225. Here, the jet hole sheet 1221 is made of a flexible material and has a floating sheet 1221a and hollow holes 1221b. The floating sheet 1221a has a sheet structure of bending vibration, and its shape and size correspond to the inner edge of the air guiding assembly arrangement region 1215. The hollow holes 1221b penetrate the center of the floating sheet 1221a and are for gas passage. In a preferred embodiment of the present invention, the rectangle of the floating sheet 1221a may be one of a square, a circle, an ellipse, a triangle, and a polygon.

[0035] The cavity frame 1222 is laminated on the jet hole sheet 1221, and its appearance corresponds to that of the jet hole sheet 1221. The actuator 1223 is laminated on the cavity frame 1222 and defines a resonance cavity 1226 together with the jet hole sheet 1221 and the floating sheet 1221a. The insulating frame 1224 is laminated on the actuator 1223, and its appearance is close to that of the cavity frame 1222. The conductive frame 1225 is laminated on the insulating frame 1224, and its appearance is close to that of the insulating frame 1224. The conductive frame 1225 has a conductive pin 1225a and a conductive electrode 1225b. Here, the conductive pin 1225a extends outward from the outer edge of the conductive frame 1225, and the conductive electrode 1225b extends inward from the inner edge of the conductive frame 1225. Further, the actuator 1223 further includes a piezoelectric mounting plate 1223a, an adjustment resonance plate 1223b, and a piezoelectric plate 1223c. The piezoelectric mounting plate 1223a is laminated on the cavity frame 1222. The adjustment resonance plate 1223b is laminated on the piezoelectric mounting plate 1223a. The piezoelectric plate 1223c is laminated on the adjustment resonance plate 1223b. The adjustment resonance plate 1223b and the piezoelectric plate 1223c are housed within the insulating frame 1224 and are electrically connected to the piezoelectric plate 1223c by the conductive electrode 1225b of the conductive frame 1225. In a preferred embodiment of the present invention, both the piezoelectric mounting plate 1223a and the adjustment resonance plate 1223b are made of a conductive material. The piezoelectric mounting plate 1223a has a piezoelectric pin 1223d. The piezoelectric pin 1223d and the conductive pin 1225a are connected to a drive circuit (not shown) on the drive circuit board 123 and receive a drive signal (which may be a drive frequency and a drive voltage). The drive signal forms a circuit through the piezoelectric pin 1223d, the piezoelectric mounting plate 1223a, the adjustment resonance plate 1223b, the piezoelectric plate 1223c, the conductive electrode 1225b, the conductive frame 1225, and the conductive pin 1225a. The insulating frame 1224 isolates the conductive frame 1225 and the actuator 1223, thereby avoiding a short-circuit phenomenon, and the drive signal is transmitted to the piezoelectric plate 1223c. After the piezoelectric plate 1223c receives the drive signal, it deforms due to the piezoelectric effect and further drives the piezoelectric mounting plate 1223a and the adjustment resonance plate 1223b to bend and vibrate reciprocally.

[0036] The adjustment resonance plate 1223b is located between the piezoelectric plate 1223c and the piezoelectric mounting plate 1223a, and can adjust the vibration frequency of the piezoelectric mounting plate 1223a as a buffer material between the two. Basically, the thickness of the adjustment resonance plate 1223b is larger than that of the piezoelectric mounting plate 1223a, and the vibration frequency of the actuator 1223 can be adjusted by adjusting the thickness of the adjustment resonance plate 1223b.

[0037] As shown in FIGS. 7A, 7B, 8A, 8B, and 9A, the jet hole sheet 1221, the cavity frame 1222, the actuator 1223, the insulating frame 1224, and the conductive frame 1225 are laminated and positioned in the gas guide assembly placement area 1215 in sequence, so that the piezoelectric actuator 122 is positioned in the gas guide assembly placement area 1215. In the piezoelectric actuator 122, a gap 1221c through which gas flows is formed between the floating sheet 1221a and the inner edge of the gas guide assembly placement area 1215. An air flow chamber 1227 is formed between the jet hole sheet 1221 and the bottom surface of the gas guide assembly placement area 1215. The air flow chamber 1227 communicates with the resonance chamber 1226 between the actuator 1223, the cavity frame 1222, and the floating sheet 1221a of the jet hole sheet 1221 through the hollow hole 1221b of the jet hole sheet 1221. Due to the vibration frequency of the gas in the resonance chamber 1226, the vibration frequency of the floating sheet 1221a becomes the same, and the resonance chamber 1226 and the floating sheet 1221a generate the Helmholtz resonance effect, which can improve the gas transport efficiency. When the piezoelectric plate 1223c moves in a direction away from the bottom surface of the gas guide assembly placement area 1215, the floating sheet 1221a of the jet hole sheet 1221 moves in a direction away from the bottom surface of the gas guide assembly placement area 1215 along with the piezoelectric plate 1223c. As a result, the volume of the air flow chamber 1227 rapidly increases, the internal pressure decreases, and a negative pressure is formed. The gas outside the piezoelectric actuator 122 is sucked in through the gap 1221c, enters the resonance chamber 1226 through the hollow hole 1221b, and the air pressure in the resonance chamber 1226 increases, forming a pressure gradient. When the piezoelectric plate 1223c moves the floating sheet 1221a of the jet hole sheet 1221 towards the bottom surface of the gas guide assembly placement area 1215, the gas in the resonance chamber 1226 is discharged faster than through the hollow hole 1221b, the gas in the air flow chamber 1227 is compressed, and the collected gas is quickly discharged in a large amount from the vent hole 1215a of the gas guide assembly placement area 1215 in an ideal gas state close to Bernoulli's theorem.

[0038] By repeating the operations shown in FIGS. 9B and 9C, the piezoelectric plate 1223c vibrates back and forth. According to the principle of inertia, since the internal air pressure in the resonance chamber 1226 after exhaust becomes lower than the equilibrium air pressure, the gas re-enters the resonance chamber 1226. 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, generating the Helmholtz resonance effect and realizing the high-speed and large-volume transportation of gas. The gas enters from the intake opening 1261a of the outer lid 126, enters the intake groove 1214 of the base 121 through the intake port 1214a, and flows to the position of the particulate sensor 125. Further, due to the continuous driving of the piezoelectric actuator 122, the gas in the intake path is sucked, the external gas is quickly introduced, flows stably, and passes above the particulate sensor 125. In this case, the laser assembly 124 emits a light beam, and the light beam enters the intake groove 1214 from the light-transmitting window 1214b and passes above the particulate sensor 125. When the light beam of the laser assembly 124 irradiates the floating particles in the gas, scattering phenomena and projection spots occur. By receiving and calculating the projection spots due to scattering by the particulate sensor 125, related information such as the particle size and concentration of the floating particles contained in the gas is obtained. Also, the gas above the particulate sensor 125 is continuously driven by the piezoelectric actuator 122 and introduced into the ventilation hole 1215a in the gas guide assembly arrangement region 1215 and enters the exhaust groove 1216. Finally, after the gas enters the exhaust groove 1216, since the piezoelectric actuator 122 continuously transports the gas to the exhaust groove 1216, the gas in the exhaust groove 1216 is pushed and discharged to the outside through the exhaust port 1216a and the exhaust opening 1261b.

[0039] 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. For example, the gas may be formaldehyde, ammonia gas, carbon monoxide, carbon dioxide, oxygen gas, ozone, etc. Therefore, the gas detector a of the present invention further includes a gas sensor 127. The gas sensor 127 is provided to be electrically connected to the drive circuit board 123, housed in the exhaust groove 1216, and detects the characteristics of the introduced gas. The gas sensor 127 may be a volatile organic compound sensor for detecting carbon dioxide or total volatile organic compound gas information. The gas sensor 127 may be a formaldehyde sensor for detecting formaldehyde gas information. The gas sensor 127 may be a bacteria sensor for detecting bacteria information or fungi information. The gas sensor 127 may be a virus sensor for detecting virus gas information. The gas sensor 127 may be a temperature and humidity sensor for detecting gas temperature and humidity information.

[0040] As shown in FIGS. 2A and 2B, the blower D1 of the gas filtration device D is activated under control to guide the air pollution so that the air pollution passes through the filter element D2 and is filtered. The filter element D2 is a high-efficiency particulate air filter U17 (ULPA17) grade or a high-efficiency particulate air filter (HEPA), and by adsorbing chemical smog, bacteria, dust particles, and pollen contained in the air pollution, it achieves the effect of filtering and purifying the introduced air pollution.

The decomposition layer is activated carbon 231, which removes organic and inorganic substances in the air pollution and removes colored and odoriferous substances. The decomposition layer may be a chlorine dioxide cleaning factor D2b, which suppresses viruses, bacteria, fungi, influenza A virus, influenza B virus, enterovirus, and norovirus in the air pollution, and the suppression rate reaches 99% or more, contributing to reducing the cross-infection of the virus.

The decomposition layer may be zeolite D2e, which removes ammonia nitrogen, heavy metals, organic pollutants, Escherichia coli, phenol, chloroform, and anionic surfactants. In some embodiments, the filter element D2 can also chemically sterilize and remove air pollution in combination with light irradiation. The light irradiation is a photocatalytic unit including a photocatalyst D2f and an ultraviolet lamp D2g. When the photocatalyst D2f is irradiated by the ultraviolet lamp D2g, it converts light energy into electrical energy and decomposes harmful substances in the air pollution to disinfect and sterilize, thereby achieving the effect of filtration and sterilization.The light irradiation may be an optical plasma unit including an optical nanotube D2h, and the optical nanotube D2h 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. In some embodiments, the filter element D2 can also be combined with a decomposition unit to chemically sterilize and remove the air pollution. The decomposition unit may be a negative ion unit D2i, which attaches the positively charged fine particles contained in the introduced air pollution to a negatively charged dust collecting plate to achieve the effect of filtering and sterilizing the introduced air pollution. The decomposition unit may be a plasma ion unit D2j, which ionizes the oxygen molecules and water molecules contained in the air pollution by the plasma ions to 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 sterilizing the introduced air pollution.

[0041] As shown in FIG. 12, the cloud computing service device 2 includes a wireless network cloud computing service module 21, a cloud control service unit 22, a device management unit 23, and an application unit 24.

The device management unit 23 can receive the communication information of the device via the wireless network cloud computing service module 21 for user login management and device binding management, and provide device management information to the application unit 24 for system control management. The application unit 24 displays and notifies the air pollution information obtained by the cloud control service unit 22, so that the user can grasp the air pollution removal situation in real time via a mobile phone or a communication device, and can control a detection cut-off prevention mechanism for the indoor air purification system via the application unit 24 of the mobile phone or the communication device.

The transmission of the air pollution information output from the gas detector 1 is realized by IoT communication. Here, the IoT communication may be realized by selecting a communication mechanism capable of performing transmission by two methods of wired communication and wireless communication. Under the monitoring mechanism of the actual handshake communication protocol of wired communication and wireless communication, one of the wired communication capable of performing transmission communication or the wireless communication capable of performing transmission communication is spontaneously selected to transmit the air pollution information output by the air pollution detection to the cloud computing service device. Further, the cloud computing service device generates a control command, feeds it back to the gas detector, and transmits it to the electrically connected drive control element. The drive control element controls the startup and operation of the gas filtration device, and realizes the detection disconnection prevention mechanism measures that the IoT communication attempts to solve. Also, when both the wired communication and the wireless communication of the air pollution information detected and output by the gas detector are disconnected, the gas detector can spontaneously calculate and compare the air pollution information, and spontaneously transmit a control command to the drive control element of the gas filtration device to control the startup and operation of the blower. As a result, the blower is activated under control, guides the air pollution so that the air pollution passes through the filter element and is filtered, the air pollution gas state in the indoor area approaches zero, meets the requirements of the clean room class, avoids the impact and injury on human health caused by gas hazards in the environment, and has a very high industrial application value.
