Abstract
Description
[Technical field]
[0001] The present invention relates to an indoor air purification system, and more particularly to an indoor air purification system adapted to make the gas conditions in an indoor area reach a clean room level of cleanliness. [Background technology]
[0002] Suspended particulates refer to solid particles or liquid droplets contained in gas. Because the particle size is very small, they can easily enter the human lungs through the nasal hairs in the nasal cavity, causing lung inflammation, asthma, cardiovascular disease, etc., and if other pollutants adhere to the suspended particulates, the harm to the respiratory system becomes even greater. In recent years, the problem of air pollution has become increasingly serious, and the concentration data of fine suspended particles (e.g., PM2.5) in particular is often too high, so monitoring the concentration of suspended particulates in gas has attracted attention. However, the flow of gas is unstable depending on the wind direction and volume, and most of the gas monitoring stations that currently detect suspended particulates are fixed-point type, so it is not possible to immediately check the concentration of suspended particulates in the surrounding area.
[0003] In addition, modern people are increasingly paying attention to the quality of gases around them, such as carbon monoxide, carbon dioxide, volatile organic compounds (VOCs), PM 2.5 Gases such as nitrogen monoxide, sulfur monoxide, and even fine particles contained in gases are all exposed in the environment and can affect human health, and in severe cases, can even be life-threatening. Therefore, the quality of environmental gases has attracted the attention of many countries, and how to detect gas quality and avoid areas with poor gas quality or move away from areas with poor gas quality has become a hot topic.
[0004] As a way to check the quality of gas, gas sensors can be used to detect the surrounding environmental gases. If the detection information can be provided in real time to alert people in the environment, so that the impacts and injuries on human health caused by environmental gas hazards can be prevented or avoided in real time, it is a very good application of using gas sensors to detect the surrounding environment.
[0005] In addition, indoor air quality is difficult to grasp. In addition to outdoor air quality, indoor air conditioning conditions and pollution sources are all major factors that affect indoor air quality. It is possible to intelligently and quickly detect indoor air pollution sources in various indoor areas, effectively remove indoor air pollution, and form a clean and safe to breathe gas state, and monitor indoor air quality in real time anytime and anywhere. Of course, in the indoor space area, if the suspended particle concentration in the indoor area is strictly controlled according to the "clean room" standard, the introduction, generation and retention of fine particles can be avoided, and the temperature and humidity can be controlled within the required range, that is, the level of the indoor space area is distinguished by the number of suspended particles in the air, and is determined by the number of fine particles (≧0.5 μm) contained in 1 cubic meter, and the clean room requirements of the indoor space area that can be safely breathed are achieved. In addition, clean rooms are divided into two types: positive pressure and negative pressure. Positive pressure clean rooms are commonly used in the semiconductor industry, mainly to prevent outdoor dust pollution, while negative pressure clean rooms are used in hospitals and some biotechnology factories, and require the indoor air pressure to be negative relative to the outdoor air pressure to prevent bacteria from leaking. Both positive pressure and negative pressure require a large amount of air exchange to achieve indoor cleanliness, and the installation costs of these clean room equipment are quite high, and when applied to the indoor space area of a home, it is difficult for general consumers to accept and introduce them. Therefore, the main task of the present invention is how to detect indoor air quality, how to solve the air pollution problem, how to make the indoor space area reach the requirements of the clean room, and how to avoid the impact and injury of human health caused by gas hazards in the environment. Summary of the Invention [Problem to be solved by the invention]
[0006] The present invention is an indoor air purification system. By mainly disposing at least one gas detector and at least one purification device in the indoor area, the gas detector can monitor and confirm air pollution at any time, and output and form air pollution information. The cloud computing service device receives air pollution information, stores a database of air pollution data, performs artificial intelligence calculation to determine the location of air pollution, issues a control command and sends it to the purification device to start operation, generates a circulating directional airflow in the indoor area, quickly guides the air pollution, and filters and removes it multiple times through the purification device, and sterilizes and completely removes it. Through the detection, purification and prevention functions of air pollution location identification-air pollution guide-air pollution removal in the indoor area, the gas state in the indoor area reaches the clean room level of cleanliness. [Means for solving the problem]
[0007] In order to achieve the above object, the present invention provides an indoor air purification system, which includes at least one gas detector, at least one purification device, and a cloud computing service device. The at least one gas detector is disposed in an indoor area, detects air pollution, and outputs and forms air pollution information.

[0009] The following description will provide detailed descriptions of the embodiments showing the features and advantages of the present invention. It should be understood that the present invention can have various modifications in different aspects, all without departing from the scope of the present invention, and the description and drawings are illustrative in nature, and are not intended to limit the present invention.
[0010] Please refer to Figures 1, 2A and 2B. The present invention is an indoor air purification system including at least one gas detector 1, at least one purification device 2, and a cloud computing service device 3. The at least one gas detector 1 is disposed in an indoor area A, detects air pollution, and outputs and forms air pollution information. The at least one purification device 2 includes an air guide device 21, a filtering component 22, and a sterilization component 23, the air guide device 21 is activated under control, and guides the air pollution to be filtered by the filtering component 22 and sterilized and removed by the sterilization component 23, and the filtering component 22 is a high-efficiency particulate air filter (HEPA). The cloud computing service device 3 receives air pollution information of indoor area A, stores a database of air pollution data, and issues control commands based on intelligent calculation (AI calculation) and intelligent selection of the air pollution data, and sends them to the air guidance device 21 of the purification device 2 to start operating, generating a circulating directional airflow in indoor area A (as shown by the dotted circulating airflow path in Figure 1), quickly guiding the air pollution in indoor area A to be filtered and removed multiple times by the filtration component 22, and sterilized and completely removed by the sterilization component 23, so that the gas state in indoor area A reaches the cleanliness level of a clean room.
[0011] The gas detector 1 is disposed in the indoor area A, detects air pollution, and outputs and forms air pollution information. A gas detection module is installed inside the gas detector 1 of the present invention. With reference to Figs. 3A and 3B, the gas detector 1 may be configured in a form with an external power supply terminal, which can be directly inserted into a power supply interface in the indoor area A to start operation and detect air pollution. Alternatively, as shown in Fig. 3C, the gas detector 1 is in the form of a gas detection module without an external power supply terminal, directly incorporated into the device (purifying device 2), and is connected to a power source to start operation and detect air pollution. The air pollution refers to any one or combination of suspended particulate matter, carbon monoxide, carbon dioxide, ozone, sulfur dioxide, nitrogen dioxide, lead, total volatile organic compounds, formaldehyde, bacteria, fungi, and viruses.
[0012] The structure of the gas detection module of the gas detector 1 of the present invention will be described in detail below. With reference to Figs. 3A to 11, the gas detection module includes a control circuit board 11, a gas detection body 12, a microprocessor 13, and a communication device 14. The gas detection body 12, the microprocessor 13, and the communication device 14 are packaged in the control circuit board 11, integrally formed, and electrically connected. The microprocessor 13 and the communication device 14 are installed on the control circuit board 11, and the microprocessor 13 controls the drive signal of the gas detection body 12 to start the detection operation, so that the gas detection body 12 detects air pollution and outputs detection information, which is processed and output by the microprocessor 13, and provided to the communication device 14 for communication transmission to the outside, and transmitted to the cloud computing service device 3. The communication transmission may be wireless communication, which is any one of a Wi-Fi module, a Bluetooth (registered trademark) module, a wireless frequency identification module, and a near-field communication module, and thus the communication device 14 of the gas detection module and the cloud computing service device 3 are connected to each other via the Internet of Things (IOT).
[0013] 4A to 9A, the gas detection main body 12 includes a base 121, a piezoelectric actuator 122, a drive circuit board 123, a laser component 124, a particulate sensor 125, and an outer lid 126. The base 121 has a first surface 1211, a second surface 1212, a laser installation area 1213, an intake groove 1214, an air-conducting component mounting area 1215, and an exhaust groove 1216. The first surface 1211 and the second surface 1212 are two surfaces that are installed opposite each other. The laser installation area 1213 is formed by hollowing out from the first surface 1211 toward the second surface 1212. The outer lid 126 covers the base 121 and has a side plate 1261 that has an intake frame opening 1261a and an exhaust frame opening 1261b. The intake groove 1214 is formed by being recessed from the second surface 1212, and is adjacent to the laser installation area 1213. The intake groove 1214 is provided with an intake vent 1214a which communicates with the outside of the base 121 and corresponds to the intake frame port 1261a of the outer lid 126, and both side walls of the intake groove 1214 are penetrated by light transmitting windows 1214b and communicate with the laser installation area 1213. Thus, the first surface 1211 of the base 121 is covered with the outer lid 126, and the second surface 1212 is covered with the drive circuit board 123, thereby defining an intake path by the intake groove 1214.
[0014] The air-conducting component mounting area 1215 is recessed from the second surface 1212, communicates with the intake groove 1214, has a ventilation hole 1215a penetrating through the bottom surface, and has positioning protrusions 1215b at each of the four corners of the air-conducting component mounting area 1215. The exhaust groove 1216 is provided with an exhaust vent 1216a that is installed corresponding to the exhaust frame opening 1261b of the outer lid 126. The exhaust groove 1216 includes a first section 1216b recessed in a vertical projection area of the first surface 1211 onto the air-conducting component mounting area 1215, and a second section 1216c hollowed out from the first surface 1211 toward the second surface 1212 in an area extending from the vertical projection area of the air-conducting component mounting area 1215, the first section 1216b is connected to the second section 1216c to form a step, and the first section 1216b of the exhaust groove 1216 communicates with the ventilation hole 1215a of the air-conducting component mounting area 1215, and the second section 1216c of the exhaust groove 1216 communicates with the exhaust vent 1216a. When the first surface 1211 of the base 121 is covered by the outer lid 126 and the second surface 1212 is covered by the drive circuit board 123, the exhaust groove 1216 and the drive circuit board 123 together define an exhaust path.
[0015] The laser component 124 and the particle sensor 125 are both installed on the drive circuit board 123 and located in the base 121. In order to clearly explain the positions of the laser component 124, the particle sensor 125, and the base 121, the drive circuit board 123 is intentionally omitted. The laser component 124 is accommodated in the laser installation area 1213 of the base 121, and the particle sensor 125 is accommodated in the intake groove 1214 of the base 121 and aligned with the laser component 124. In addition, the laser component 124 corresponds to the light transmission window 1214b through which the laser light emitted by the laser component 124 passes, thereby irradiating the laser light to the intake groove 1214. The beam path emitted by the laser component 124 passes through the light transmission window 1214b and is perpendicular to the intake groove 1214. The beam emitted by the laser component 124 passes through the light-transmitting window 1214b into the intake groove 1214, and irradiates the gas in the intake groove 1214. When the beam comes into contact with the gas, it scatters to generate a projected spot, and the particle sensor 125 is located at a position perpendicular to the gas sensor, and receives and calculates the scattered projected spot to obtain gas detection data.
[0016] The piezoelectric actuator 122 is accommodated in a square air-conducting component mounting area 1215 of the base 121. The air-conducting component mounting area 1215 is connected to the air intake groove 1214. When the piezoelectric actuator 122 is activated, the gas in the air intake groove 1214 is sucked into the piezoelectric actuator 122, and the gas passes through the air vent hole 1215a of the air-conducting component mounting area 1215 and enters the exhaust groove 1216. The driving circuit board 123 covers the second surface 1212 of the base 121. The laser component 124 is installed and electrically connected to the driving circuit board 123. The particle sensor 125 is also installed and electrically connected to the driving circuit board 123. When the outer cover 126 covers the base 121, the air intake frame port 1261a corresponds to the air intake vent port 1214a of the base 121, and the exhaust frame port 1261b corresponds to the exhaust vent port 1216a of the base 121.
[0017] The piezoelectric actuator 122 includes a gas orifice plate 1221, a chamber housing 1222, an actuator 1223, an insulating housing 1224, and a conductive housing 1225. The gas orifice plate 1221 is made of a flexible material and has a suspension plate 1221a and a hollow hole 1221b, the suspension plate 1221a is a sheet-like structure that vibrates in bending, and its shape and dimensions correspond to the inner edge of the air-conducting component mounting area 1215, and the hollow hole 1221b penetrates the center of the suspension plate 1221a to allow gas to flow through. In a preferred embodiment of the present invention, the shape of the suspension plate 1221a may be any of a square, a circle, an ellipse, a triangle, and a polygon.
[0018] The chamber housing 1222 is stacked on the gas orifice plate 1221, and its appearance corresponds to the gas orifice plate 1221. The actuator 1223 is stacked on the chamber housing 1222, and defines a resonant chamber 1226 between the actuator 1223 and the suspension plate 1221a of the gas orifice plate 1221. The insulating housing 1224 is stacked on the actuator 1223, and its appearance is similar to the chamber housing 1222. The conductive housing 1225 is stacked on the insulating housing 1224, and its appearance is similar to the insulating housing 1224. The conductive housing 1225 has a conductive pin 1225a and a conductive electrode 1225b, where the conductive pin 1225a extends outward from the outer edge of the conductive housing 1225, and the conductive electrode 1225b extends inward from the inner edge of the conductive housing 1225. The actuator 1223 further includes a piezoelectric carrier plate 1223a, a resonance adjustment plate 1223b, and a piezoelectric plate 1223c. The piezoelectric carrier plate 1223a is stacked on the chamber housing 1222. The resonance adjustment plate 1223b is stacked on the piezoelectric carrier plate 1223a. The piezoelectric plate 1223c is stacked on the resonance adjustment plate 1223b. The resonance adjustment plate 1223b and the piezoelectric plate 1223c are housed in an insulating housing 1224. The conductive electrode 1225b of the conductive housing 1225 is electrically connected to the piezoelectric plate 1223c. In a preferred embodiment of the present invention, the piezoelectric carrier plate 1223a and the resonance adjustment plate 1223b are both made of conductive materials. The piezoelectric carrier plate 1223a has a piezoelectric pin 1223d, and the piezoelectric pin 1223d and the conductive pin 1225a are connected to a driving circuit (not shown) on the driving circuit board 123 to receive a driving signal (which may be a driving frequency and a driving voltage). The driving signal can form a loop through the piezoelectric pin 1223d, the piezoelectric carrier plate 1223a, the resonance adjustment plate 1223b, the piezoelectric plate 1223c, the conductive electrode 1225b, the conductive housing 1225, and the conductive pin 1225a, and the insulating housing 1224 can cut off the conductive housing 1225 and the actuator 1223 to prevent a short circuit phenomenon, and the driving signal can be transmitted to the piezoelectric plate 1223c. After receiving the driving signal, the piezoelectric plate 1223c is deformed by the piezoelectric effect, and further drives the piezoelectric carrier plate 1223a and the resonance adjustment plate 1223b to generate a reciprocating bending vibration.
[0019] More specifically, the resonance adjusting plate 1223b is located between the piezoelectric plate 1223c and the piezoelectric carrier plate 1223a as a buffer between them, and can adjust the vibration frequency of the piezoelectric carrier plate 1223a. Basically, the thickness of the resonance adjusting plate 1223b is greater than that of the piezoelectric carrier plate 1223a, and the vibration frequency of the actuator 1223 is adjusted by changing the thickness of the resonance adjusting plate 1223b.
[0020] 7A, 7B, 8A, 8B, and 9A, the gas orifice plate 1221, the chamber housing 1222, the actuator 1223, the insulating housing 1224, and the conductive housing 1225 are stacked and positioned in order in the air-conducting component mounting area 1215, so that the piezoelectric actuator 122 is positioned in the air-conducting component mounting area 1215, and the piezoelectric actuator 122 defines a gap 1221c for gas flow between the suspension plate 1221a and the inner edge of the air-conducting component mounting area 1215. An airflow chamber 1227 is formed between the gas orifice plate 1221 and the bottom surface of the air-conducting component mounting area 1215. The airflow chamber 1227 is connected to a resonant chamber 1226 between the actuator 1223, the chamber housing 1222, and the suspension plate 1221a of the gas orifice plate 1221 via a hollow hole 1221b in the gas orifice plate 1221. By making the vibration frequency of the gas in the resonant chamber 1226 the same as the vibration frequency of the suspension plate 1221a, the resonant chamber 1226 and the suspension plate 1221a generate a Helmholtz resonance effect, thereby increasing the gas transport efficiency. When the piezoelectric plate 1223c moves away from the bottom surface of the air-conducting component mounting area 1215, the piezoelectric plate 1223c moves the suspension plate 1221a of the gas orifice plate 1221 away from the bottom surface of the air-conducting component mounting area 1215, causing the volume of the airflow chamber 1227 to expand suddenly, the internal pressure to decrease and generate negative pressure, and gas outside the piezoelectric actuator 122 is sucked in and flows in through the gap 1221c, passes through the hollow hole 1221b, and enters the resonating chamber 1226, increasing the air pressure in the resonating chamber 1226 and generating a pressure gradient. When the piezoelectric plate 1223c moves the suspension plate 1221a of the gas orifice plate 1221 to the bottom surface of the air-conducting component mounting area 1215, the gas in the resonating chamber 1226 quickly flows out through the hollow hole 1221b, squeezing out the gas in the airflow chamber 1227, and the merged gas is quickly and in large quantities ejected in an ideal gas state close to Bernoulli's theorem, and introduced into the ventilation hole 1215a of the air-conducting component mounting area 1215.
[0021] 9B and 9C, the piezoelectric plate 1223c vibrates back and forth, and according to the principle of inertia, when the internal air pressure of the resonating chamber 1226 after exhaust becomes lower than the equilibrium air pressure, the gas is guided back into the resonating chamber 1226. In this way, the vibration frequency of the gas in the resonating chamber 1226 is controlled to be the same as the vibration frequency of the piezoelectric plate 1223c, thereby generating the Helmholtz resonance effect and realizing high-speed and large-volume gas transport. All the gas enters from the intake frame port 1261a of the outer cover 126, passes through the intake vent 1214a, enters the intake groove 1214 of the base 121, and flows to the position of the particle sensor 125. In addition, the gas in the intake path is absorbed by the continuous driving of the piezoelectric actuator 122, so that the external gas is rapidly introduced and stably circulated, passing above the particle sensor 125. At this time, the beam emitted by the laser component 124 passes through the light transmission window 1214b, enters the intake groove 1214, and passes above the particle sensor 125. When the beam of the laser component 124 is irradiated to the suspended particles in the gas, a scattering phenomenon and a projection spot are generated, so that the particle sensor 125 receives the projection spot caused by scattering and performs calculations to obtain related information such as the particle size and concentration of the suspended particles contained in the gas. The gas above the particle sensor 125 is also introduced into the ventilation hole 1215a of the air guide component mounting area 1215 by the continuous driving of the piezoelectric actuator 122, and enters the exhaust groove 1216. Finally, after the gas enters the exhaust groove 1216, the piezoelectric actuator 122 continues to transport the gas to the exhaust groove 1216, so that the gas in the exhaust groove 1216 is pushed out and discharged to the outside through the exhaust vent 1216a and the exhaust frame port 1261b.
[0022] The gas detector 1 of the present invention can not only detect suspended particles in the gas, but also detect the characteristics of the introduced gas, such as formaldehyde, ammonia, carbon monoxide, carbon dioxide, oxygen gas, and ozone. Therefore, the gas detector 1 of the present invention further includes a gas sensor 127, which is positioned and installed on the driving circuit board 123, electrically connected, and accommodated in the exhaust groove 1216 to detect the characteristics of the introduced gas. The gas sensor 127 may be a volatile organic compound sensor that detects gas information of carbon dioxide or total volatile organic compounds. The gas sensor 127 may be a formaldehyde sensor that detects gas information of formaldehyde. The gas sensor 127 may be a bacteria sensor that detects bacteria information or fungus information. The gas sensor 127 may be a virus sensor that detects gas information of viruses. The gas sensor 127 may be a temperature and humidity sensor that detects gas temperature and humidity information.
[0023] Also, referring to FIG. 1, FIG. 2A, and FIG. 2B, the above-mentioned purifying device 2 includes an air guide device 21, a filtering part 22, and a sterilizing part 23. The air guide device 21 is activated under control to guide air pollution to be filtered by the filtering part 22 and sterilized and removed by the sterilizing part 23. The filtering part 22 is a high-efficiency particulate air filter (HEPA) that adsorbs chemical smog, bacteria, dust particles, and pollen contained in the air pollution, thereby achieving the effect of filtering and purifying the introduced air pollution. As shown in FIG. 2A, the airflow path direction of the above-mentioned air guide device 21 is the direction indicated by the arrow, and the air guide device 21 may be installed in front of the filtering part 22 or behind the filtering part 22. The sterilizing part 23 can chemically sterilize and remove air pollution by applying a decomposition layer to the filtering part 22. The decomposition layer is activated carbon 231, which removes organic and inorganic substances in the air pollution and removes colored substances and odorous substances. The decomposition layer may be a chlorine dioxide purifying agent 232, which inhibits viruses, bacteria, fungi, influenza A virus, influenza B virus, enteric virus, and norovirus in air pollution, with an inhibition rate of more than 99%, contributing to reducing cross-infection of viruses. The decomposition layer may be a herbal protective layer 233 including ginkgo and Japanese Rhus chinensis, which effectively resists allergies and destroys the surface protein of influenza viruses (e.g., H1N1). The decomposition layer may be silver ions 234, which inhibits viruses, bacteria, and fungi in the introduced air pollution. The decomposition layer may be zeolite 235, which removes ammonia nitrogen, heavy metals, organic pollutants, E. coli, phenol, chloroform, and anionic surfactants. In some embodiments, the filtration component 22 can also chemically remove air pollution in combination with light irradiation. The light irradiation is a photocatalyst unit including a photocatalyst 236 and an ultraviolet lamp 237. When the photocatalyst 236 is irradiated by the ultraviolet lamp 237, the light energy is converted into electrical energy, and harmful substances in air pollution are decomposed and disinfected, thereby achieving the effects of filtering and purifying.The light irradiation may be an optical plasma unit including an optical nanotube 238, and the optical nanotube 238 irradiates the introduced air pollution to decompose the oxygen molecules and water molecules in the air pollution into optical plasma having high oxidizing properties, forming an ion airflow having destroyed organic molecules, and decomposing gas molecules such as volatile formaldehyde, toluene, and volatile organic compounds (VOCs) contained in the air pollution into water and carbon dioxide, thereby achieving the effect of filtering and purifying. In some embodiments, the filtering component 22 may be combined with a decomposition unit to chemically remove the air pollution. The decomposition unit may be a negative ion unit 239, which attaches the positively charged fine particles contained in the introduced air pollution to a negatively charged dust collecting plate, thereby achieving the effect of filtering and purifying the introduced air pollution.
