Description

[Technical field]

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

[0002] Suspended particulate matter refers to solid particles or liquid droplets contained in the gas. Due to their very fine size, they can easily enter the lungs through the nasal hairs in the nasal cavity, causing lung inflammation, asthma or cardiovascular disease. If other pollutants are attached to the suspended particulate matter, the harm to the respiratory system will be aggravated. In recent years, the problem of gas pollution has become increasingly serious, especially fine suspended particulate matter (such as PM 2.5 ) concentration data is often too high, and 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 most of the gas quality monitoring stations that detect suspended particulates are currently fixed points, it is impossible to confirm the current surrounding suspended particulate concentration.

[0003] In addition, modern people are paying more and more attention to the quality of the air around them, such as carbon monoxide, carbon dioxide, volatile organic compounds (VOC), PM 2.5 , nitric oxide, sulfur oxide and other gases, and even the particles contained in the gases, will be exposed to the environment and affect human health, and even endanger life in serious cases. Therefore, the quality of environmental gases has attracted the attention of all countries. How to detect gas quality to avoid and stay away from areas with poor gas quality is a current topic of concern.

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

[0005] In addition, indoor air quality is not easy to grasp. In addition to outdoor air quality, indoor air conditioning conditions and pollution sources are the main factors affecting indoor air quality. Indoor air pollution sources can be intelligently and quickly detected in various indoor fields, effectively removing indoor air pollution to form a clean and safe gas state, and real-time monitoring of indoor air quality can be performed anytime and anywhere. Of course, if the indoor field can strictly control the concentration of suspended particulate matter 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 is distinguished by the number of suspended particles in the air, and the number of suspended particles in the air pollution is distinguished by the number of particles contained in 1 cubic meter, so as to achieve the clean room requirements of indoor fields that can be safely breathed. Therefore, how to detect indoor air quality and how to solve the problem of air pollution, so that the indoor field can meet the requirements of the clean room and avoid the harm of gas in the environment and the impact and harm to human health, this is the main subject developed by the present invention. [Summary of the invention]

The air is filtered and removed to zero and sterilized and removed through the sterilization component, thereby improving the purification efficiency of the indoor space and reducing the environmental noise of the indoor space. In this way, the indoor air purification system forms the detection, purification and prevention benefits of locating air pollution - draining air pollution - zeroing air pollution, and the filter component of the purification device filters air pollution at the high-efficiency particulate air filter (HEPA) level, and the fan of the purification device is equipped with a specific clean air output (CADR) to generate a circulating directional airflow, so that the gas state of the indoor space is achieved to meet the clean room grade requirements formed by the cleanliness specifications of the number of particles, avoiding the impact and harm to human health caused by the hazards of gases in the environment.

[0012] The gas detector 1 mentioned above has a gas detection module disposed therein. Figure 3A and Figure 3B As shown, the gas detector 1 can be a type of structure with an external power terminal, which can be directly plugged into the power interface in the indoor field B to start the operation of air pollution detection. Figure 3CThe gas detection module type shown does not contain an external power terminal, is directly constructed on the device (purification device 2), and is connected to a power source to start the operation to detect air pollution.

[0013] 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. The above-mentioned intelligent computing includes artificial intelligence (AI) computing and edge computing. The above-mentioned Internet of Things (IoT) refers to the collective network connecting various devices and the technology that helps devices communicate with the cloud and between devices.

[0014] The following is a detailed description of the gas detection module structure of the gas detector 1 of the present invention. Figures 3A to 11 As shown, the 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 in the control circuit board 11 to form a whole and are electrically connected to each other. The microprocessor 13 and the communicator 14 are arranged on the control circuit board 11, and the microprocessor 13 controls the driving signal of the gas detection body 12 to start the detection operation, so that the gas detection body 12 detects air pollution and outputs a detection information, which is then processed by the microprocessor 13 and provided to the communicator 14 for external transmission to the cloud computing service device 4 through the Internet of Things (IoT) communication. The Internet of Things (IoT) of the present embodiment is that the gas detector 1 communicates with the cloud computing service device 4 through wireless communication, and the wireless communication can be one of a Wi-Fi module, a Bluetooth module, a wireless radio frequency identification module, and a near field communication module.

[0015] Please see again 4A to 9AAs 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.

[0016] 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.

[0017] The laser assembly 124 and the particle sensor 125 are both disposed on the driving circuit board 123 and located in the base 121. In order to clearly explain the positions of the laser assembly 124 and the particle sensor 125 and the base 121, the driving circuit board 123 is omitted. The laser assembly 124 is accommodated in the laser setting area 1213 of the base 121, and the particle sensor 125 is accommodated in the air inlet groove 1214 of the base 121 and aligned with the laser assembly 124. In addition, the laser assembly 124 corresponds to the light-transmitting window 1214b, and the light-transmitting window 1214b allows the laser light emitted by the laser assembly 124 to pass through, so that the laser light is irradiated to the air inlet groove 1214. The path of the light beam emitted by the laser assembly 124 is to pass through the light-transmitting window 1214b and form an orthogonal direction with the air inlet groove 1214. The laser component 124 emits a light beam through the light-transmitting window 1214b into the air intake groove 1214, and the detection data in the gas in the air intake groove 1214 is irradiated. When the light beam contacts the gas, it will scatter and generate a projected light spot, so that the particle sensor 125 is located in its orthogonal direction and receives the projected light spot generated by the scattering for calculation to obtain the detection data of the gas.

[0018] 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 .

[0019] 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.

[0020] 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 further includes a piezoelectric carrier 1223a, an adjustment resonance plate 1223b and a piezoelectric plate 1223c. The piezoelectric carrier 1223a is stacked on the cavity frame 1222. The adjustment resonance plate 1223b is stacked on the piezoelectric carrier 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 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 vibrations.

[0021] Further, 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.

[0022] Please refer to Fig. 7A , Figure 7B , Fig. 8A , Figure 8B and Fig.9A As shown, the jet hole sheet 1221, the cavity frame 1222, the actuator 1223, the insulating frame 1224 and the conductive frame 1225 are stacked and positioned in sequence in the air guide component support area 1215, so that the piezoelectric actuator 122 is positioned in the air guide component support area 1215. The piezoelectric actuator 122 defines a gap 1221c between the suspension sheet 1221a and the inner edge of the air guide component support area 1215 for gas circulation. An airflow chamber 1227 is formed between the jet hole sheet 1221 and the bottom surface of the air guide component support area 1215. The airflow chamber 1227 is connected to the resonant chamber 1226 between the actuator 1223, the airflow hole sheet 1221 and the suspension sheet 1221a through the hollow hole 1221b of the airflow hole sheet 1221. The vibration frequency of the gas in the resonant chamber 1226 is made close to the vibration frequency of the suspension sheet 1221a, so that the resonant chamber 1226 and the suspension sheet 1221a can produce a Helmholtz resonance effect, thereby improving the gas transmission efficiency. When the piezoelectric plate 1223c moves away from the bottom surface of the air guide component supporting area 1215, the piezoelectric plate 1223c drives the suspension plate 1221a of the jet hole plate 1221 to move away from the bottom surface of the air guide component supporting area 1215, so that the volume of the airflow chamber 1227 expands rapidly, the internal pressure drops to produce negative pressure, and the gas outside the piezoelectric actuator 122 flows in through the gap 1221c and enters the resonance chamber 1226 through the hollow hole 1221b, increasing the air pressure in the resonance chamber 1226 and thus producing a pressure gradient. When the piezoelectric plate 1223c drives the suspended plate 1221a of the jet hole plate 1221 to move toward the bottom surface of the air guide component supporting area 1215, the gas in the resonance chamber 1226 quickly flows out through the hollow hole 1221b, squeezing the gas in the air flow chamber 1227, and making the converged gas quickly and massively ejected out of the air hole 1215a of the air guide component supporting area 1215 in an ideal gas state close to Bernoulli's principle.

[0023] 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 .

[0026] Please see again Figure 1 , Fig.11 As shown, a gas detector 1 can be directly set on the purification device 2. The gas detection module architecture of the gas detector 1 is connected to the power supply and control driving circuit on the purification device 2, so that the communicator 14 of the gas detection module and the cloud computing service device 4 can communicate with each other through the Internet of Things (IoT). At this time, the cloud computing service device 4 issues a control instruction to control the fan 21 of the purification device 2 to start the regulation operation. The start-up regulation operation is based on the air pollution information detected by the indoor field B. Through the intelligent calculation and comparison of the big data database of the air pollution data of the cloud computing service device 4, the start-up time cycle and the air volume of the fan 21 of the purification device 2 are regulated to improve the purification efficiency of the indoor field B and reduce the environmental noise of the indoor field B, so that the indoor field B generates a circulating directional airflow, and the air pollution in the indoor field B is quickly drained through the filter component 22 for multiple filtration and removal to zero and sterilized and removed through the sterilization component 23. In some specific embodiments, multiple gas detectors 1 and multiple purification devices 2 are arranged in the indoor field B, wherein the indoor air pollution information detected by at least two or more gas detectors 1 is output to the cloud computing service device 4 through the Internet of Things communication, and the intelligent computing judgment can find the air pollution location in the indoor field B, and intelligently select and issue control instructions to transmit to multiple purification devices 2, so as to mobilize and control the fan 21 of the purification device 2 closest to the air pollution location to start operation to generate a directional airflow, and then mobilize and control the fans 21 of other purification devices 2 to start operation, so that the indoor field B generates a circulating directional airflow, and the air pollution in the indoor field B is quickly drained through the filter component 22 for multiple times to be filtered and removed to zero, and sterilized and removed through the sterilization component 23, so that the gas state of the indoor field B is formed to a clean room grade according to the cleanliness specification of the number of particles.

[0027] Please see again Figure 1As shown, the present invention can further be provided with a gas exchange device 3 to provide gas from the outdoor field A to be introduced into the indoor field B for ventilation. When the gas exchange device 3 is started, the gas is introduced and exported along the arrow path shown in the figure to implement ventilation between the indoor field B and the outdoor field A.

The command is transmitted to the wireless network cloud computing service module 41, and then transmitted to the gas exchange device 3 and the fan 21 of the purification device 2 through the wireless network cloud computing service module 41 to control the start-up operation. The device management unit 43 receives the communication information of the purification device 2 and the gas exchange device 3 through the wireless network cloud computing service module 41 as user login management and device binding management, and can provide the device management information to the application unit 44 for system control management.
