Description

TECHNICAL FIELD

[0001] The present application relates to a ceiling type air filter unit, in particular to a ceiling type air filter unit for detecting and purifying indoor air pollution. BACKGROUND

[0002] Suspended particles refer to solid particles or liquid droplets contained in the gas. Because the particle size is very fine, it can easily enter the lungs of the human body through the nasal hair in the nasal cavity, causing inflammation, asthma or cardiovascular disease in the lungs, and if other pollutants are attached to the suspended particles, the harm to the respiratory system will be more serious. In recent years, air pollution problems have become increasingly serious, especially the concentration data of fine suspended particles (such as PM2.5) are often too high, and the monitoring of gas suspended particle concentration has been paid more and more attention. However, because the gas flows unstably with the wind direction and wind volume, and the current gas quality monitoring station for detecting suspended particles is mostly fixed, it is impossible to confirm the current ambient suspended particle concentration.

[0003] In addition, modern people pay more and more attention to the air quality around their lives, such as carbon monoxide, carbon dioxide, volatile organic compounds (VOC), PM2.5, nitrogen monoxide, sulfur monoxide and other gases, and even the particles contained in the gas, which will affect human health in the environment, and even endanger life. Therefore, the quality of the environment is paid attention to by various countries, and how to detect the quality of the gas to avoid and escape from the area with poor gas quality is the current topic.

[0004] How to confirm the quality of the gas, it is feasible to use a gas sensor to detect the ambient environment gas, and if it can provide detection information in real time, warn people in the environment, so that they can prevent or escape in time, avoid the harm of the gas in the environment and cause the influence and harm to the human health, using the gas sensor to detect the surrounding environment can be said to be a very good application.

[0005] In addition, the 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. The indoor air pollution source can be detected intelligently and quickly in various indoor fields, effectively removing indoor air pollution to form a clean and safe breathing gas state, and the indoor air quality can be monitored at any time and anywhere.

[0006] In addition, the indoor air quality is not easy to grasp. In addition to the outdoor air quality, the indoor air conditioning condition and the pollution source are the main factors affecting the indoor air quality. The indoor air pollution source can be intelligently and quickly detected in various fields of the indoor space. The indoor air pollution can be effectively removed to form a clean and safe breathing gas state. The indoor air quality can be monitored at any time and anywhere. Of course, if the indoor field can be strictly controlled according to the "clean room" standard to strictly control the indoor field of the suspended particle concentration, the particle introduction, generation and retention are avoided, and the temperature and humidity are controlled within the required range, the clean room requirement of the indoor field of the safe breathing indoor field is achieved.

[0007] Therefore, how to detect the indoor air quality in the indoor space and how to solve the air pollution problem to achieve the cleanliness requirement of the clean room in the indoor field and avoid the harm of the gas in the environment to the human body are the main topics of the present application.

It should be understood that the present application can be implemented in various ways, none of which depart from the scope of the present application, and that the description and drawings are to be regarded as illustrative in nature and not as restrictive.

[0109] It is worth noting that the embedded fan filter unit in the space of indoor field A is used for air pollution detection and purification to zero, and is embedded in the space of indoor field A without the need for piping design. The longitudinal parallel isolation of the flow channel 24 and the filter air duct 24b effectively suppresses the backflow effect of the circulating filtered gas, and realizes the air pollution purification to zero clean room processing. The indoor field A requires a clean room of ZAP Clean room 1-12 level.

[0110] Please refer to Figure 1B As shown in the drawings, the present application provides an embedded fan filter unit for an indoor air cleaning networking mechanism system, wherein the indoor air cleaning networking mechanism system comprises: a plurality of gas detectors 1 arranged to detect air pollution information and gas temperature and humidity information in an indoor field A and an outdoor field B, and the indoor field A is provided with at least one air inlet C1 and at least one air outlet C2, and at least one control gas molecule hardware device, wherein the control gas molecule hardware device comprises at least one embedded fan filter unit, at least one embedded gas exchange device 4 corresponding to the air inlet C1, at least one cleaning machine 5, at least one exhaust device 6 corresponding to the air outlet C2, at least one exhaust system 7 corresponding to the air outlet C2, at least one air conditioning device 8, at least one dust collector 9 and at least one dehumidifier 10 arranged in the indoor field A, and each control gas molecule hardware device is internally provided with at least one gas detector 1, at least one air guide 21, at least one filter assembly 22 and at least one drive controller 23, and the gas detector 1 is electrically connected with the drive controller 23, and the networking cloud computing service device 3 receives the air pollution information and the gas temperature and humidity information of the indoor field A and the outdoor field B detected by the gas detector 1 through the Internet of Things communication, stores and forms an air pollution big data database, and intelligently selects and sends a control instruction to the gas detector 1 for receiving, to control the drive controller 23 to start the operation of the air guide 21, so that the indoor field A can be ventilated, the temperature and humidity can be adjusted, and the air pollution can be purified to zero through the filter assembly 22 for multiple times, and the gas detector 1 transmits the air pollution information and the gas temperature and humidity information in the indoor field A to the outside.

[0111] Of course, the above-mentioned gas detector 1 is arranged in the indoor field A and the outdoor field B to detect air pollution information and gas temperature and humidity information, and outputs the air pollution information and the gas temperature and humidity information through the Internet of Things (IoT) communication. It is worth noting that the gas detector 1 is internally provided with a gas detection module, please refer to Figure 3A and Figure 3B As shown in the drawings, the gas detector 1 can be a type of external power terminal, which is directly inserted into the power interface in the indoor field A to start operation and detect air pollution, or as Figure 3CThe gas detection module shown without external power terminal is directly structured on the control gas molecule hardware equipment (embedded fan filter unit, embedded gas exchange device 4, purifier 5, exhaust device 6, exhaust system 7, air conditioning device 8, dust collector 9 and dehumidifier 10) and is electrically connected to receive a control instruction to control the power supply of the control gas molecule hardware equipment to start the operation of the fan 21.

[0112] The above-mentioned Internet of Things communication refers to a collective network connecting various devices and a technology helping devices and clouds and devices to communicate with each other. The Internet of Things communication can be a wired communication for connecting the cloud computing service device 3 through a wired line. The Internet of Things communication can be a wireless communication for communicating with the cloud computing service device 3 through a wireless connection. 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.

[0113] It is worth noting that the above-mentioned air pollution refers to one or a combination of suspended particulate matter, carbon monoxide, carbon dioxide, ozone, sulfur dioxide, nitrogen dioxide, lead, total volatile organic compounds, formaldehyde, bacteria, fungi, and viruses.

[0114] Of course, each gas detector 1 monitors the air quality in the space of the indoor field A at any time and anywhere, detects the air pollution information in the space of the indoor field A, and transmits the air pollution big data to the air pollution big data database of the cloud computing service device 3. The intelligent comparison of the environmental air quality state immediately controls the air volume of the fan 21 of the control gas molecule hardware equipment in each region to adjust the air volume, thereby effectively controlling the energy saving benefit of the operation of the control gas molecule hardware equipment.

[0115] To understand the specific implementation of the embedded fan filter unit provided by the present application, the gas detection module structure of the gas detector 1 of the present application will be described in detail. Please refer to Figures 3A to 11 As shown, the above-mentioned gas detection module 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 on the control circuit board 11 to form an integrated body 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. Thus, the gas detection body 12 detects the air pollution and outputs a detection information. The microprocessor 13 processes and outputs the data to the communicator 14, which transmits the data to the cloud computing service device 3 through the Internet of Things (IoT) communication.

[0116] Please also refer to Figures 4A to 9AAs shown, the gas detection main body 12 includes a base 121, a piezoelectric actuator 122, a driving circuit board 123, a laser assembly 124, a particulate sensor 125, and a cover 126. The base 121 has a first surface 1211, a second surface 1212, a laser setting area 1213, an air inlet groove 1214, a gas guide assembly bearing area 1215, and an air outlet groove 1216. The first surface 1211 and the second surface 1212 are oppositely arranged. The laser setting area 1213 is hollowed out from the first surface 1211 toward the second surface 1212. In addition, the cover 126 covers the base 121 and has a side plate 1261 with an air inlet frame opening 1261a and an air outlet frame opening 1261b. The air inlet groove 1214 is recessed from the second surface 1212 and adjacent to the laser setting area 1213. The air inlet groove 1214 is provided with an air inlet opening 1214a, which is connected to the outside of the base 121 and corresponds to the air outlet opening 1216a of the 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 communicate with the laser setting area 1213. Therefore, the first surface 1211 of the base 121 is covered by the cover 126, and the second surface 1212 is covered by the driving circuit board 123, so that the air inlet groove 1214 defines an air inlet path. The gas guide assembly bearing area 1215 is recessed from the second surface 1212 and communicates with the air inlet groove 1214, and a gas passage hole 1215a is formed in the bottom surface, and the four corners of the gas guide assembly bearing area 1215 are respectively provided with a positioning protrusion 1215b. The air outlet groove 1216 is provided with an air outlet opening 1216a, which corresponds to the air outlet frame opening 1261b of the cover 126. The air outlet groove 1216 includes a first interval 1216b recessed from the vertical projection area of the gas guide assembly bearing area 1215 on the first surface 1211, and a second interval 1216c formed by hollowing out from the first surface 1211 to the second surface 1212 in the area extending from the vertical projection area of the gas guide assembly bearing area 1215, wherein the first interval 1216b and the second interval 1216c are connected to form a step difference, and the first interval 1216b of the air outlet groove 1216 communicates with the gas passage hole 1215a of the gas guide assembly bearing area 1215, and the second interval 1216c of the air outlet groove 1216 communicates with the air outlet opening 1216a. Therefore, when the first surface 1211 of the base 121 is covered by the 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 together define an air outlet path.

[0117] The laser assembly 124 and the particle sensor 125 are disposed on the driving circuit board 123 and located in the base 121. In order to clearly show the positions of the laser assembly 124, 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 transmission window 1214b, which is used for the laser emitted by the laser assembly 124 to pass through, so that the laser irradiates the air inlet groove 1214. The light beam path emitted by the laser assembly 124 passes through the light transmission window 1214b and forms a perpendicular direction with the air inlet groove 1214. The light beam emitted by the laser assembly 124 enters the air inlet groove 1214 through the light transmission window 1214b, and the detection data in the gas in the air inlet groove 1214 is irradiated. When the light beam contacts the gas, it will scatter and generate a projection point. The particle sensor 125 is located in the position perpendicular to the direction and receives the projection point generated by the scattering to calculate and obtain the detection data of the gas.

[0118] The piezoelectric actuator 122 is accommodated in the square air guide assembly carrying area 1215 of the base 121. In addition, the air guide assembly carrying area 1215 communicates with the air inlet groove 1214. When the piezoelectric actuator 122 is actuated, the gas in the air inlet groove 1214 enters the piezoelectric actuator 122, and the gas passes through the air hole 1215a of the air guide assembly carrying area 1215 and enters the air outlet groove 1216. In addition, the driving circuit board 123 is covered on the second surface 1212 of the base 121. The laser assembly 124 is disposed on the driving circuit board 123 and electrically connected. The particle sensor 125 is also disposed on the driving circuit board 123 and electrically connected. When the cover 126 covers the base 121, the air outlet port 1216a corresponds to the air inlet port 1214a of the base 121, and the air outlet port 1261b corresponds to the air outlet port 1216a of the base 121.

[0119] The piezoelectric actuator 122 includes a gas jet hole sheet 1221, a cavity frame 1222, an actuator 1223, an insulating frame 1224 and a conductive frame 1225. The gas jet hole sheet 1221 is a flexible material and has a suspension sheet 1221a and a hollow hole 1221b. The suspension sheet 1221a is a curved vibration sheet structure, which corresponds to the inner edge of the air guide assembly carrying area 1215 in shape and size. The hollow hole 1221b penetrates the center of the suspension sheet 1221a for gas flow. In the preferred embodiment of the present application, the shape of the suspension sheet 1221a can be one of square, pattern, oval, triangle and polygon.

[0120] The cavity frame 1222 is stacked on the air jet sheet 1221 and has the same shape as the air jet sheet 1221. The actuating body 1223 is stacked on the cavity frame 1222 and defines a resonance chamber 1226 with the air jet sheet 1221 and the suspension sheet 1221a. The insulating frame 1224 is stacked on the actuating body 1223 and has the same shape as the cavity frame 1222. The conductive frame 1225 is stacked on the insulating frame 1224 and has the same shape as the insulating frame 1224. The conductive frame 1225 has a conductive pin 1225a and a conductive electrode 1225b extending outwardly from the outer edge of the conductive pin 1225a. The conductive electrode 1225b extends inwardly from the inner edge of the conductive frame 1225. In addition, the actuating body 1223 includes a piezoelectric carrier plate 1223a, a resonance adjusting plate 1223b and a piezoelectric plate 1223c. The piezoelectric carrier plate 1223a is stacked on the cavity frame 1222. The resonance adjusting plate 1223b is stacked on the piezoelectric carrier plate 1223a. The piezoelectric plate 1223c is stacked on the resonance adjusting plate 1223b. The resonance adjusting plate 1223b and the piezoelectric plate 1223c are accommodated in the insulating frame 1224. The conductive electrode 1225b of the conductive frame 1225 is electrically connected to the piezoelectric plate 1223c. In the preferred embodiment of the present application, the piezoelectric carrier plate 1223a and the resonance adjusting plate 1223b are made of conductive material. The piezoelectric carrier plate 1223a has a piezoelectric pin 1223d. The piezoelectric pin 1223d is connected to a driving circuit (not shown) on the driving circuit board 123 to receive a driving signal (which can be a driving frequency and a driving voltage). The driving signal forms a loop through the piezoelectric pin 1223d, the piezoelectric carrier plate 1223a, the resonance adjusting plate 1223b, the piezoelectric plate 1223c, the conductive electrode 1225b, the conductive frame 1225 and the conductive pin 1225a. The insulating frame 1224 prevents the conductive frame 1225 from short-circuiting with the actuating body 1223, so that the driving signal can be transmitted to the piezoelectric plate 1223c. The piezoelectric plate 1223c deforms due to the piezoelectric effect after receiving the driving signal, which further drives the piezoelectric carrier plate 1223a and the resonance adjusting plate 1223b to produce a reciprocating bending vibration.

[0121] Further, the resonance adjusting plate 1223b is located between the piezoelectric plate 1223c and the piezoelectric carrier plate 1223a and serves as a buffer therebetween to adjust the vibration frequency of the piezoelectric carrier plate 1223a. Basically, the thickness of the resonance adjusting plate 1223b is greater than that of the piezoelectric carrier plate 1223a. The vibration frequency of the actuating body 1223 is adjusted by changing the thickness of the resonance adjusting plate 1223b.

[0122] Please refer to Figure 7A , Figure 7B , Figure 8A , Figure 8B andFigure 9A As shown, the jet orifice plate 1221, the cavity frame 1222, the actuating body 1223, the insulating frame 1224 and the conductive frame 1225 are sequentially stacked and positioned within the air guide assembly bearing area 1215, so that the piezoelectric actuator 122 is positioned within the air guide assembly bearing area 1215, and defines a gap 1221c between the suspension plate 1221a and the inner edge of the air guide assembly bearing area 1215 for gas flow. The jet orifice plate 1221 and the bottom surface of the air guide assembly bearing area 1215 form a gas flow chamber 1227 therebetween. The gas flow chamber 1227 is in communication with the resonance chamber 1226 between the actuating body 1223, the jet orifice plate 1221 and the suspension plate 1221a through the hollow hole 1221b of the jet orifice plate 1221, so that the vibration frequency of the gas in the resonance chamber 1226 is close to the vibration frequency of the suspension plate 1221a, and the resonance chamber 1226 and the suspension plate 1221a generate Helmholtz resonance, thereby improving the transmission efficiency of the gas. When the piezoelectric plate 1223c moves away from the bottom surface of the air guide assembly bearing area 1215, the piezoelectric plate 1223c drives the suspension plate 1221a of the jet orifice plate 1221 to move away from the bottom surface of the air guide assembly bearing area 1215, so that the volume of the gas flow chamber 1227 is rapidly expanded, the internal pressure is reduced to generate negative pressure, the gas outside the piezoelectric actuator 122 is attracted to flow into the gap 1221c, and then enters the resonance chamber 1226 through the hollow hole 1221b, thereby increasing the gas pressure in the resonance chamber 1226 and generating a pressure gradient. When the piezoelectric plate 1223c drives the suspension plate 1221a of the jet orifice plate 1221 to move toward the bottom surface of the air guide assembly bearing area 1215, the gas in the resonance chamber 1226 rapidly flows out through the hollow hole 1221b, presses the gas in the gas flow chamber 1227, and makes the gathered gas rapidly and massively sprayed into the air hole 1215a of the air guide assembly bearing area 1215 in the ideal gas state close to Bernoulli's law.

[0123] By repeating Figure 9B With Figure 9CThe piezoelectric actuator 122 drives the gas in the inlet path to facilitate the rapid introduction and stable flow of external gas, and the gas passes above the particle sensor 125. At this time, the laser assembly 124 emits a light beam through the light-transmitting window 1214b into the inlet channel 1214, which passes above the particle sensor 125. When the light beam of the particle sensor 125 strikes the suspended particles in the gas, scattering and projection points are generated. The particle sensor 125 receives the projection points generated by scattering to calculate the particle size and concentration of the suspended particles in the gas and other related information. The gas above the particle sensor 125 is also continuously driven by the piezoelectric actuator 122 into the air hole 1215a of the air guide assembly bearing area 1215 and into the outlet channel 1216. Finally, when the gas enters the outlet channel 1216, the piezoelectric actuator 122 continuously transports the gas into the outlet channel 1216, so that the gas in the outlet channel 1216 is pushed and discharged to the outside through the outlet port 1216a and the outlet frame port 1261b.

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; and the gas sensor 127 can be a temperature and humidity sensor to detect gas temperature and humidity information.
