Description

Technical Field

[0001] The present invention relates to an indoor air purification system, and in particular to a detection disconnection prevention mechanism of the indoor air purification system. Background Art

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

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

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

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

[0006] The air pollution detection of the indoor air purification system currently provided is that the gas detector detects and transmits the air pollution information, which is then transmitted to the cloud computing service device through the Internet of Things communication to receive the air pollution information of the outdoor field and the indoor field to store and form a big data database of air pollution data, and intelligently calculates and compares the big data database of air pollution data, and intelligently selects to send a control instruction to the fan of the gas filtering device to start the regulation operation, so that the indoor field continuously generates an internal circulation directional airflow, and the air pollution is drained and filtered through the filter element for multiple times, so that the gas state of the indoor field can reach the clean room grade formed by the cleanliness specification of the number of suspended particulate particles; however, the air pollution information output by the air pollution detection is transmitted through the Internet of Things communication. If the Internet of Things communication of the detection transmission is disconnected, it will affect the drainage and air pollution filtering operation of the gas filtering device. How to prevent the disconnection of the Internet of Things communication and solve the detection mechanism measures are the main topics developed by the present invention. Summary of the invention

[0007] The main purpose of the present invention is to provide a detection disconnection prevention mechanism for an indoor air purification system. A gas detector is set on each indoor gas filter device to implement air pollution detection, transmit air pollution information, and receive control instructions to electrically connect the driving control element of the gas filter device. The driving control element regulates the gas filter device to start operation, and outputs air pollution information in the gas detector. The transmission is realized through Internet of Things communication. It uses the Internet of Things communication, which can be a dual mode of wired communication and wireless communication, to select an operable transmission communication mechanism to achieve it. Under the monitoring mechanism of the actual handshake communication protocol of wired communication and wireless communication, it independently judges and selects the wired communication that can operate the transmission communication or the wireless communication that can operate the transmission communication to achieve air The air pollution information output by the pollution detection is transmitted to the cloud computing service device, and then the cloud computing service device generates a control instruction to feed back to the gas detector and transmit it to the electrically connected drive control element, and the drive control element regulates the gas filter device to start operation, thereby realizing a detection disconnection prevention mechanism measure to be solved by Internet of Things communication; in addition, when the air pollution information output by the gas detector is disconnected in both wired communication and wireless communication, the gas detector can autonomously calculate and compare the air pollution information, and autonomously issue a control instruction to the drive control element of the gas filter device to regulate the fan to start operation, so that the fan is controlled to start and guide the air pollution to pass through the filter element for filtration, so that the air pollution gas state in the indoor field tends to zero to meet the clean room grade requirements.

[0008] To achieve the above-mentioned purpose, the present invention provides a detection disconnection prevention mechanism for an indoor air purification system, comprising: at least one gas filtering device, arranged in the indoor field, comprising a fan, a filter element, a gas detector and a drive control element, wherein the gas detector detects an air pollutant and outputs the air pollutant information through an Internet of Things communication, and the gas detector receives a control instruction to the drive control element through the Internet of Things communication to control the fan to start operation, and the fan is controlled to start and guide the air pollutant to pass through the filter element for filtration; a cloud computing service device receives the air pollutant information detected and output by the gas detector through the Internet of Things communication and stores it to form an air pollutant data The control command is intelligently selected to send the control command to the gas detector of the gas filter device for receiving and transmitting to the drive control element for regulating the fan to start operation; wherein, when the Internet of Things communication is disconnected in the handshake communication protocol, the air pollution information output by the gas detector is detected and compared with the air pollution information independently, and the control command is sent to the drive control element for regulating the fan to start operation, and the fan is controlled to start and guide the air pollution to pass through the filter element for filtration, so that the air pollution gas state of the indoor field approaches zero to meet the clean room grade requirements.

[0120] Embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different aspects without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0121] See also Figure 1A and Figure 1B The figure shows a schematic diagram of the indoor air purification system of the present invention in use in an indoor field. Therefore, in order to realize a detection disconnection prevention mechanism measure to be solved in the indoor air purification system to prevent the disconnection of the Internet of Things communication, the present invention further provides a detection disconnection prevention mechanism for the indoor air purification system, including:

[0122] At least one gas filtering device D is arranged in the indoor field A, and includes a fan D1, a filter element D2, a gas detector 1 and a drive control element D3, wherein the gas detector 1 detects air pollution and outputs air pollution information through an Internet of Things communication, and the gas detector 1 receives a control instruction to the drive control element D3 through the Internet of Things communication to control the fan D1 to start operation, and the fan D1 is controlled to start and guide the air pollution to pass through the filter element D2 for filtration. It is worth noting 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.

[0123] The cloud computing service device 2 receives the air pollution information output by the gas detector 1 through the Internet of Things communication and stores it to form a large data database of air pollution data. It also intelligently calculates and compares the large data database of air pollution data, and intelligently selects to send a control instruction to the gas detector 1 of the gas filter device to receive and transmit it to the drive control element D3 to adjust the fan D1 to start the operation. The fan D1 is controlled to start and guide the air pollution to pass through the filter element D2 for filtration, so that the air pollution gas state of the indoor field A tends to zero to meet the clean room grade requirements. It is worth noting that the Internet of Things (IoT) communication refers to the collective network connecting various devices and the technology that helps devices communicate with the cloud and each other.

[0124] The above-mentioned Internet of Things communication is a wired communication, which is connected to the cloud computing service device 2 for communication through a wired line. The cloud computing service device 2 receives the air pollution information and performs intelligent calculation and comparison, and intelligently selects to send a control instruction to the gas detector 1 for receiving and transmitting it to the driving control element D3. The driving control element D3 regulates the fan D1 of the gas filtering device D to start operation. The fan D1 is controlled to start and guide the air pollution to pass through the filtering element D2 for filtration, so that the air pollution gas state of the indoor field A is approached to zero to meet the clean room grade requirements.

[0125] The aforementioned Internet of Things communication is a wireless communication, which is used to communicate with the cloud computing service device 2 through a wireless connection, and the cloud computing service device 2 receives the air pollution information and performs intelligent calculation comparison, and intelligently selects to send a control instruction to the gas detector 1 to receive and transmit it to the driving control element D3 to control the fan D1 of the gas filter device D to start operation. The fan D1 is controlled to start and guide the air pollution through the filter element D2 for filtration, so that the air pollution gas state of the indoor field A tends to zero to meet the clean room grade requirements. The wireless communication can be one of a Wi-Fi module, a Bluetooth module, a wireless radio frequency identification module, and a near field communication module.

[0126] Of course, the above-mentioned Internet of Things communication is able to determine whether the handshake communication protocol of wired communication and wireless communication is disconnected, and adjust and select a start-up mechanism of wired communication or wireless communication that can be operated for transmission. The cloud computing service device 2 receives the air pollution information and performs intelligent calculation and comparison through the start-up mechanism of wired communication or wireless communication that can be operated for transmission, and intelligently selects to send a control instruction to the gas detector 1 for receiving and transmitting it to the drive control element D3 to adjust the fan D1 to start operation. The fan D1 is controlled to start and guide the air pollution to pass through the filter element D2 for filtration, so that the air pollution gas state of the indoor field A is approached to zero to meet the clean room grade requirements. Furthermore, when the wired communication and wireless communication of the Internet of Things communication are disconnected in the handshake communication protocol, the air pollution information output by the gas detector 1 can be independently calculated and compared with the air pollution information, and a control instruction is automatically issued to the drive control element D3 to control the fan D1 to start operation. The fan D1 is controlled to start and guide the air pollution to pass through the filter element D2 for filtration, so that the air pollution gas state of the indoor field A is brought close to zero to meet the clean room grade requirements.

[0127] Furthermore, the gas filter device D can be installed in the indoor space A in a built-in or plug-in manner. Figure 1A and Figure 1BAs shown), at least one circulating return air channel C is set in the indoor field A, which is surrounded and isolated by a number of partitions C1 and formed on the side of the indoor field A, and is provided with a plurality of air inlets C2 and a plurality of return air inlets C3, and the gas filtering device D is set in the circulating return air channel C of the indoor field A and corresponds to the air inlet C2.

[0128] Furthermore, in the present embodiment, if Figure 1A and Figure 1B As shown, the gas filter device D can be a gas exchange device 1D, which is connected to an air inlet channel 1D1 and is connected to the gas of an outdoor field B. The gas detector 1 of the gas exchange device 1D receives a control instruction through the Internet of Things communication and transmits it to the driving control element D3 to control the fan D1 to start operation, so that the gas of the outdoor field B is introduced into the indoor field A for ventilation. It is worth noting that Figure 1A and Figure 1B As shown, multiple gas detectors a are further arranged in the indoor field A and the outdoor field B to detect air pollution and output air pollution information. The gas detector a is internally provided with a gas detection module, such as Figure 3A and Figure 3B The gas detector a shown in the figure may be a gas detector having an external power terminal. The external power terminal is directly inserted into the power interface in the indoor field A or the power interface arranged in the outdoor field B to start the operation of air pollution detection. The gas detector a is similar to the gas detector a shown in the figure. Figure 3C The gas detector 1 shown in the figure, which does not include an external power terminal and is constructed in the form of a gas detection module, has the same role and function, except that the gas detector 1 is directly constructed in the form of a gas detection module on the gas filter device D to detect air pollution, and is electrically connected to a drive control element D3, and can receive a control instruction to the drive control element D3 to control the fan D1 of the gas exchange device 1D to start operation. It is worth noting that the gas exchange device 1D can be a fresh air fan.

[0129] In addition, the above-mentioned gas detector a outputs air pollution information through the Internet of Things communication, and the cloud computing service device 2 receives the air pollution information of the indoor field A and the outdoor field B to store and form a big data database of air pollution data, and intelligently calculates and compares the air pollution information of the indoor field A and the outdoor field B. When the air pollution information of the indoor field A is higher than the air pollution information of the outdoor field B, the cloud computing service device 2 sends a control instruction to the gas detector a through the Internet of Things communication to receive the control instruction and transmit it to the driving control element D3 to adjust the fan D1 of the gas exchange device 1D to start operation, and provide the gas of the outdoor field B to be introduced into the indoor field A for ventilation, wherein the air pollution information of the outdoor field B and the indoor field A is the air pollution data of carbon dioxide (CO2), and the air pollution information of carbon dioxide (CO2) detected by the gas detector 1 must maintain a safe value air pollution data below 800PPM. If the safe value air pollution data is exceeded, the gas exchange device 1D provides the gas of the outdoor field B to be introduced into the indoor field A for ventilation. It is worth noting that a valve 1D2 is provided between the air duct 1D1 and the gas connection of the outdoor field B, which is controlled by the driving control element D3. When the gas detector 1 receives the control instruction, it transmits it to the driving control element D3 to regulate the fan D1 of the gas exchange device 1D to start operation, and at the same time controls the opening of the valve 1D2 to connect the air duct 1D1 with the gas of the outdoor field B, so that the gas of the outdoor field B can be introduced into the indoor field A for ventilation.

[0130] The above-mentioned gas filtering device D can be a circulating filtering device 2D. The gas detector 1 transmits air pollution information to the cloud computing service device 2 to form a big data database of air pollution data, and intelligently calculates and compares to intelligently select and issue control instructions. The gas detector 1 receives the control instruction through the Internet of Things communication and transmits it to the driving control element D3 to control the fan D1 of the circulating filtering device 2D to start operation, and the induced air pollution is filtered through the filter element D2 and discharged from the air inlet C2 into the space of the indoor field A.

[0131] The gas filter device D can be an air conditioning device 3D, which is set in the indoor field A to adjust the temperature and humidity. The gas detector 1 receives the control command through the Internet of Things communication and transmits it to the driving control element D3 to adjust the air conditioning device 3D to start operation, and the gas detector 1 transmits the temperature and humidity information of the gas in the indoor field A to the cloud computing service device 2 to receive and form a big data database of air pollution data. It is worth noting that the temperature and humidity control is to adjust the indoor field A to maintain a temperature of 25℃±3℃ and a humidity of 50%±10%.

[0132] The gas filtering device D can be a negative pressure exhaust fan 4D, such as Figure 1B and Figure 1CAs shown, it is arranged at the kitchen unit A1 position of the indoor field A, and is provided with an air intake channel 4D1 connecting to the outdoor field B. The gas detector 1 transmits air pollution information to the cloud computing service device 2 for receiving and forming a big data database of air pollution data, and performs intelligent calculation and comparison to intelligently select and issue control instructions. The gas detector 1 receives the control instruction through the Internet of Things communication and transmits it to the driving control element D3 to regulate the fan D1 of the negative pressure exhaust fan 4D to start operation, and the induced air pollution is filtered by the filter element D2, so that the air pollution in the indoor field A is accelerated to be discharged to the outdoor field B.

[0133] The gas filtering device D can be a smoke exhauster 5D, such as Figure 1B and Figure 1C As shown, it is arranged at the kitchen unit A1 position of the indoor field A and embedded in the circulating return air channel, and is provided with an air intake channel 5D1 connecting to the outdoor field B. The gas detector 1 transmits air pollution information to the cloud computing service device 2 for receiving and forming a big data database of air pollution data, and performs intelligent calculation and comparison to intelligently select and issue control instructions. The gas detector 1 receives the control instruction through the Internet of Things communication and transmits it to the driving control element D3 to regulate the fan D1 of the smoke exhaust fan 5D to start operation, and the induced air pollution is filtered by the filter element D2, so that the air pollution in the indoor field A is accelerated to be discharged to the outdoor field B.

[0134] The gas filtering device D can be a bathroom exhaust fan 6D, such as Figure 1B As shown, the bathroom unit A2 is set at the indoor field A, and an air inlet channel 6D1 is provided to connect to the outdoor field B. The gas detector 1 transmits air pollution information to the cloud computing service device 2 to form a big data database of air pollution data, and intelligently calculates and compares to intelligently select and issue control instructions. The gas detector 1 receives the control instruction through the Internet of Things communication and transmits it to the drive control element D3 to control the bathroom exhaust fan 6D to start operation, and the drainage air pollution is filtered by the filter element D2, so that the air pollution in the indoor field A is accelerated to be discharged to the outdoor field B. At the same time, the gas detector 1 of the bathroom exhaust fan 6D receives the control instruction issued by the cloud computing service device 2 through the Internet of Things communication to the drive control element D3 to control the bathroom exhaust fan 6D to start operation, so that the indoor field A implements temperature and humidity control. It is worth noting that the temperature and humidity control is to adjust the temperature in the indoor field A to maintain 25℃±3℃ and 50%±10% humidity.

[0135] As can be seen from the above description, the present invention provides a detection disconnection prevention mechanism for an indoor air purification system. In specific implementation, a gas detector 1 is set on each indoor gas filter device D to implement air pollution detection, transmit air pollution information, and receive control instructions to electrically connect the drive control element D3 of the gas filter device D. The drive control element D3 regulates the gas filter device D to start operation, and outputs air pollution information in the gas detector 1. The transmission is realized through Internet of Things communication. It uses the Internet of Things communication, which can be a dual mode of wired communication and wireless communication, to select an operable transmission communication mechanism to achieve it. Under the monitoring mechanism of the actual handshake communication protocol of wired communication and wireless communication, it independently judges and selects a wired communication that can operate the transmission communication or a wireless communication that can operate the transmission communication to select a mechanism to realize the transmission of the air pollution information output by the air pollution detection to the cloud computing service device 2, and then the cloud computing service device 2 generates a control instruction to feed back to the gas detector 1 to transmit it to the electrically connected drive control element D3, and the drive control element D3 regulates the gas filter device D to start operation, thereby realizing a detection disconnection prevention mechanism measure to be solved by Internet of Things communication; in addition, when the gas detector detects the air pollution output 1,

[0136] When both wired and wireless communications are disconnected, the gas detector 1 can autonomously calculate and compare air pollution information, and autonomously send control instructions to the driving control element D3 of the gas filter device D to control the fan D1 to start operation, so that the fan D1 is controlled to start and guide the air pollution to pass through the filter element D2 for filtration, so that the air pollution gas state of the indoor field A is close to zero to meet the clean room grade requirements.

[0137] In addition, the detection disconnection prevention mechanism of the indoor air purification system provided by the present invention receives the air pollution information of the indoor field A and the outdoor field B through the Internet of Things communication by the cloud computing service device 2 to store and form a big data database of air pollution data, and receives the gas temperature and humidity information output by the air conditioning device 3D, and intelligently calculates and compares the big data database of air pollution data and the gas temperature and humidity information, and intelligently selects to send a control instruction to the fan D1 of the gas filter device D to start the regulation operation, so that the indoor field A continuously generates an internal circulation directional airflow, and the air pollution is repeatedly drained through the filter element D2 for filtration and removal; that is, the cloud computing service device 2 calculates the indoor air pollution data by intelligent calculation. The real-time cleanliness of the number of suspended particulate matter in field A is detected, and control instructions are sent to multiple gas filter devices D intelligently. The fan D1 of the gas filter device D is activated in a timely manner. The air volume and the start-up time of the fan D1 are randomly adjusted according to the real-time cleanliness of the number of suspended particulate matter. The cleanliness efficiency of indoor field A is improved and the environmental noise of indoor field A is reduced.

[0139] To understand the specific implementation of the detection disconnection prevention mechanism of the indoor air purification system provided by the present invention, the above-mentioned gas detector 1 and gas detector a both have the same function gas detection module, but differ in appearance. The gas detection module structure of the gas detector 1 and the gas detector a is described in detail below.

[0140] See also Figures 3A to 11 As shown in the figure, the gas detector 1 comprises: a control circuit board 11, a gas detection body 12, a microprocessor 13 and a communicator 14. The gas detection body 12, the microprocessor 13 and the communicator 14 are packaged in the control circuit board 11 to form a whole and are electrically connected to each other. The microprocessor 13 and the communicator 14 are arranged on the control circuit board 11, and the microprocessor 13 controls the driving signal of the gas detection body 12 to start the detection operation. In this way, the gas detection body 12 detects air pollution and outputs a detection information, which is then processed by the microprocessor 13 and provided to the communicator 14 for external transmission to the cloud computing service device 2 through the Internet of Things (IoT) communication.

[0141] Please see again 4A to 9A As shown, the gas detection body 12 comprises a base 121, a piezoelectric actuator 122, a driving circuit board 123, a laser assembly 124, a particle sensor 125 and an outer cover 126. The base 121 has a first surface 1211, a second surface 1212, a laser setting area 1213, an air inlet groove 1214, an air guide assembly bearing area 1215 and an air outlet groove 1216. The first surface 1211 and the second surface 1212 are two surfaces arranged opposite to each other. The laser setting area 1213 is hollowed out from the first surface 1211 toward the second surface 1212. In addition, the outer cover 126 covers the base 121 and has a side plate 1261, and the side plate 1261 has an air inlet frame 1261a and an air outlet frame 1261b. The air inlet groove 1214 is formed by being recessed from the second surface 1212 and is adjacent to the laser setting area 1213. The air inlet groove 1214 is provided with an air inlet port 1214a, which is connected to the outside of the base 121 and corresponds to the air outlet port 1216a of the outer cover 126, and the two side walls of the air inlet groove 1214 penetrate the light-transmitting window 1214b of the piezoelectric actuator 122 and are connected to the laser setting area 1213. Therefore, the first surface 1211 of the base 121 is covered by the outer cover 126, and the second surface 1212 is covered by the actuator circuit board 123, so that the air inlet groove 1214 defines an air inlet path.

[0142] The air guide component carrying area 1215 is formed by a depression of the second surface 1212, and is connected to the air inlet groove 1214, and has an air hole 1215a on the bottom surface, and each of the four corners of the air guide component carrying area 1215 has a positioning protrusion 1215b. The above-mentioned air outlet groove 1216 is provided with an air outlet port 1216a, and the air outlet port 1216a is correspondingly arranged with the air outlet frame port 1261b of the outer cover 126. The air outlet groove 1216 includes a first section 1216b formed by the vertical projection area of ​​the first surface 1211 being recessed to the air guide component bearing area 1215, and an area extending from the vertical projection area of ​​the air guide component bearing area 1215, and a second section 1216c formed by hollowing out from the first surface 1211 to the second surface 1212, wherein the first section 1216b is connected to the second section 1216c to form a step difference, and the first section 1216b of the air outlet groove 1216 is communicated with the vent hole 1215a of the air guide component bearing area 1215, and the second section 1216c of the air outlet groove 1216 is communicated with the air outlet 1216a. Therefore, when the first surface 1211 of the base 121 is covered by the outer cover 126 and the second surface 1212 is covered by the driving circuit board 123, the air outlet groove 1216 and the driving circuit board 123 jointly define an air outlet path.

[0143] The laser assembly 124 and the particle sensor 125 are both disposed on the driving circuit board 123 and located in the base 121. In order to clearly explain the positions of the laser assembly 124 and the particle sensor 125 and the base 121, the driving circuit board 123 is omitted. The laser assembly 124 is accommodated in the laser setting area 1213 of the base 121, and the particle sensor 125 is accommodated in the air inlet groove 1214 of the base 121 and aligned with the laser assembly 124. In addition, the laser assembly 124 corresponds to the light-transmitting window 1214b, and the light-transmitting window 1214b allows the laser emitted by the laser assembly 124 to pass through, so that the laser is irradiated to the air inlet groove 1214. The path of the light beam emitted by the laser assembly 124 is to pass through the light-transmitting window 1214b and form an orthogonal direction with the air inlet groove 1214. The laser component 124 emits a light beam through the light-transmitting window 1214b into the air intake groove 1214, and the detection data in the gas in the air intake groove 1214 is irradiated. When the light beam contacts the gas, it will scatter and generate a projected light spot, so that the particle sensor 125 is located in its orthogonal direction and receives the projected light spot generated by the scattering for calculation to obtain the detection data of the gas.

[0144] The piezoelectric actuator 122 is accommodated in the square gas guide component carrying area 1215 of the base 121. In addition, the gas guide component carrying area 1215 is connected to the air inlet groove 1214. When the piezoelectric actuator 122 is actuated, the gas in the air inlet groove 1214 is drawn into the piezoelectric actuator 122, and the gas is supplied to enter the gas outlet groove 1216 through the vent hole 1215a of the gas guide component carrying area 1215. In addition, the driving circuit board 123 is sealed on the second surface 1212 of the base 121. The laser component 124 is disposed on the driving circuit board 123 and is electrically connected. The particle sensor 125 is also disposed on the driving circuit board 123 and is electrically connected. When the outer cover 126 is covered on the base 121 , the air outlet 1216 a corresponds to the air inlet 1214 a of the base 121 , and the air outlet frame opening 1261 b corresponds to the air outlet 1216 a of the base 121 .

[0145] The piezoelectric actuator 122 comprises an air jet hole sheet 1221, a cavity frame 1222, an actuator 1223, an insulating frame 1224 and a conductive frame 1225. The air jet hole sheet 1221 is made of a flexible material and has a suspension sheet 1221a and a hollow hole 1221b. The suspension sheet 1221a is a sheet structure that vibrates in bending, and its shape and size correspond to the inner edge of the air guide component bearing area 1215, while the hollow hole 1221b runs through the center of the suspension sheet 1221a for gas circulation. In a preferred embodiment of the present invention, the shape of the suspension sheet 1221a can be one of a square, a figure, an ellipse, a triangle and a polygon.

[0146] The cavity frame 1222 is stacked on the jet hole sheet 1221, and its appearance corresponds to the jet hole sheet 1221. The actuator 1223 is stacked on the cavity frame 1222, and defines a resonance chamber 1226 between the jet hole sheet 1221 and the suspension sheet 1221a. The insulating frame 1224 is stacked on the actuator 1223, and its appearance is similar to the cavity frame 1222. The conductive frame 1225 is stacked on the insulating frame 1224, and its appearance is similar to the insulating frame 1224, and the conductive frame 1225 has a conductive pin 1225a and a conductive electrode 1225b extending outward from the outer edge of the conductive pin 1225a, and the conductive electrode 1225b extends inward from the inner edge of the conductive frame 1225. In addition, the actuator 1223 also includes a piezoelectric carrier 1223a, an adjustment resonance plate 1223b and a piezoelectric plate 1223c. The piezoelectric carrier plate 1223a is stacked on the cavity frame 1222. The adjustment resonance plate 1223b is stacked on the piezoelectric carrier plate 1223a. The piezoelectric plate 1223c is stacked on the adjustment resonance plate 1223b. The adjustment resonance plate 1223b and the piezoelectric plate 1223c are accommodated in the insulating frame 1224. The piezoelectric plate 1223c is electrically connected to the conductive electrode 1225b of the conductive frame 1225. In a preferred embodiment of the present invention, the piezoelectric carrier plate 1223a and the adjustment resonance plate 1223b are both conductive materials. The piezoelectric carrier 1223a has a piezoelectric pin 1223d, and the piezoelectric pin 1223d and the conductive pin 1225a are connected to the driving circuit (not shown) on the driving circuit board 123 to receive the driving signal (which may be the driving frequency and the driving voltage). The driving signal can form a loop by the piezoelectric pin 1223d, the piezoelectric carrier 1223a, the adjustment resonance plate 1223b, the piezoelectric plate 1223c, the conductive electrode 1225b, the conductive frame 1225 and the conductive pin 1225a, and the insulating frame 1224 blocks the conductive frame 1225 and the actuator 1223 to avoid short circuit, so that the driving signal can be transmitted to the piezoelectric plate 1223c. After receiving the driving signal, the piezoelectric plate 1223c is deformed due to the piezoelectric effect, which further drives the piezoelectric carrier plate 1223a and the adjustment resonance plate 1223b to generate reciprocating bending vibration.

[0147] To further illustrate, the adjustment resonance plate 1223b is located between the piezoelectric plate 1223c and the piezoelectric carrier plate 1223a, and serves as a buffer between the two to adjust the vibration frequency of the piezoelectric carrier plate 1223a. Basically, the thickness of the adjustment resonance plate 1223b is greater than that of the piezoelectric carrier plate 1223a, and the vibration frequency of the actuator 1223 is adjusted by changing the thickness of the adjustment resonance plate 1223b.

[0148] Please refer to Fig. 7A , Figure 7B , Fig. 8A , Figure 8B and Fig.9A As shown, the jet hole sheet 1221, the cavity frame 1222, the actuator 1223, the insulating frame 1224 and the conductive frame 1225 are stacked and positioned in sequence in the air guide component support area 1215, so that the piezoelectric actuator 122 is positioned in the air guide component support area 1215. The piezoelectric actuator 122 defines a gap 1221c between the suspension sheet 1221a and the inner edge of the air guide component support area 1215 for gas circulation. An airflow chamber 1227 is formed between the jet hole sheet 1221 and the bottom surface of the air guide component support area 1215. The airflow chamber 1227 is connected to the resonant chamber 1226 between the actuator 1223, the airflow hole sheet 1221 and the suspension sheet 1221a through the hollow hole 1221b in the airflow hole sheet 1221. The vibration frequency of the gas in the resonant chamber 1226 is made close to the vibration frequency of the suspension sheet 1221a, so that the resonant chamber 1226 and the suspension sheet 1221a can generate a Helmholtz resonance effect, thereby improving the gas transmission efficiency. When the piezoelectric plate 1223c moves away from the bottom surface of the air guide component supporting area 1215, the piezoelectric plate 1223c drives the suspension plate 1221a of the jet hole plate 1221 to move away from the bottom surface of the air guide component supporting area 1215, so that the volume of the airflow chamber 1227 expands rapidly, the internal pressure drops to produce negative pressure, and the gas outside the piezoelectric actuator 122 flows in through the gap 1221c and enters the resonance chamber 1226 through the hollow hole 1221b, increasing the air pressure in the resonance chamber 1226 and thus producing a pressure gradient. When the piezoelectric plate 1223c drives the suspended plate 1221a of the jet hole plate 1221 to move toward the bottom surface of the air guide component supporting area 1215, the gas in the resonance chamber 1226 quickly flows out through the hollow hole 1221b, squeezing the gas in the air flow chamber 1227, and making the converged gas quickly and massively ejected out of the air hole 1215a of the air guide component supporting area 1215 in an ideal gas state close to Bernoulli's law.

[0149] By repetition Fig. 9B and Fig. 9CIn the action shown, the piezoelectric plate 1223c vibrates reciprocatingly. According to the inertia principle, the internal air pressure of the resonance chamber 1226 after exhaust is lower than the equilibrium air pressure, which will guide the gas to enter the resonance chamber 1226 again. In this way, the vibration frequency of the gas in the resonance chamber 1226 is controlled to be the same as the vibration frequency of the piezoelectric plate 1223c, so as to produce the Helmholtz resonance effect and realize the high-speed and large-volume transmission of the gas. The gas enters from the air inlet 1214a of the outer cover 126, enters the air inlet groove 1214 of the base 121 through the air inlet 1214a, and flows to the position of the particle sensor 125. Furthermore, the continuous movement of the piezoelectric actuator 122 will absorb the gas in the air intake path, so as to facilitate the rapid introduction and stable circulation of external gas, and pass through the top of the particle sensor 125. At this time, the laser component 124 emits a light beam through the light-transmitting window 1214b to enter the air intake groove 1214. The air intake groove 1214 passes above the particle sensor 125. When the light beam of the particle sensor 125 irradiates the suspended particles in the gas, scattering and projected light spots will occur. When the particle sensor 125 receives the projected light spots generated by the scattering, it calculates to obtain relevant information such as the particle size and concentration of the suspended particles contained in the gas, and the gas above the particle sensor 125 is also continuously driven by the piezoelectric actuator 122 and introduced into the vent 1215a of the air guide component supporting area 1215, and enters the air outlet groove 1216. Finally, when the gas enters the gas outlet groove 1216 , since the piezoelectric actuator 122 continuously delivers the gas into the gas outlet groove 1216 , the gas in the gas outlet groove 1216 will be pushed and discharged to the outside through the gas outlet port 1216 a and the gas outlet frame port 1261 b .

[0150] The gas detector a of the present invention can not only detect suspended particles in the gas, but also further detect the characteristics of the introduced gas, such as formaldehyde, ammonia, carbon monoxide, carbon dioxide, oxygen, ozone, etc. Therefore, the gas detector a of the present invention further includes a gas sensor 127, which is positioned and electrically connected to the driving circuit board 123, and is accommodated in the gas outlet groove 1216 to detect the characteristics of the introduced gas. The gas sensor 127 can be a volatile organic compound sensor to detect carbon dioxide or total volatile organic compound gas information; the gas sensor 127 can be a formaldehyde sensor to detect formaldehyde gas information; the gas sensor 127 can be a bacteria sensor to detect bacteria information or fungus information; the gas sensor 127 can be a virus sensor to detect virus gas information; the gas sensor 127 can be a temperature and humidity sensor to detect gas temperature and humidity information.

The decomposition layer may be a ginkgo and Japanese saltwort herbal protective layer D2c, which is effective in resisting allergies and destroying the surface proteins of influenza viruses (e.g., H1N1). The decomposition layer may be a silver ion D2d, which inhibits the introduction of viruses, bacteria, and fungi in the air pollution. The decomposition layer may be a 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 be used in combination with a chemical method of light irradiation to sterilize and remove air pollution. The light irradiation is a photocatalyst unit of a photocatalyst D2f and an ultraviolet lamp D2g. When the photocatalyst D2f is irradiated by the ultraviolet lamp D2g, the light energy can be converted into electrical energy to decompose harmful substances in the air pollution and sterilize and sterilize to achieve the filtering and sterilization effect. The light irradiation can be a photoelectric plasma unit of a nanotube D2h. The nanotube D2h irradiates the introduced air pollution, decomposing oxygen molecules and water molecules in the air pollution into highly oxidizing photoelectric plasma, forming an ion flow that can destroy organic molecules, and volatile formaldehyde, toluene, and volatile organic gases (Volatile Organic Compounds, VOC) and other gas molecules are decomposed into water and carbon dioxide to achieve the effect of filtering and sterilization; and in some embodiments, the filter element D2 can also be combined with a decomposition unit to sterilize the air pollution by chemical means, and the decomposition unit can be a negative ion unit D2i, so that the positively charged particles contained in the introduced air pollution are attached to the negatively charged particles, so as to achieve the effect of filtering and sterilizing the introduced air pollution. The decomposition unit can be a plasma ion unit D2j, which uses plasma ions to ionize the oxygen molecules and water molecules contained in the air pollution to generate cations (H+) and anions (O2-), and the substances with water molecules attached around the ions are attached to the surface of viruses and bacteria. After that, under the action of chemical reactions, they will be converted into highly oxidizing active oxygen (hydroxyl, OH group), thereby taking away the hydrogen of the proteins on the surface of viruses and bacteria, and oxidizing and decomposing them, so as to achieve the effect of filtering and sterilizing the introduced air pollution.
