[0001] This invention relates to a controller for detecting and eliminating air pollution, and more particularly to a central controller suitable for eliminating air pollution in an indoor space. [Background Technology]

[0002] As people pay increasing attention to the air quality around them, particulate matter (PM) such as PM1 and PM2.5 are becoming increasingly important. 2.5 PM 10 Gases such as carbon dioxide, total volatile organic compounds (TVOC), and formaldehyde, as well as particulate matter, aerosols, bacteria, and viruses contained in these gases, can all affect human health when exposed to the environment, and in severe cases, even endanger life.

[0003] Indoor air quality is not easy to control. In addition to outdoor air quality, the condition of indoor air conditioning and sources of pollution are the main factors affecting indoor air quality, especially dust caused by poor indoor air circulation. In order to quickly improve the indoor air environment and achieve good air quality, people often use air conditioners or air filters to improve indoor air quality.

[0004] Therefore, the main research topic of this invention is to intelligently and quickly detect indoor air pollution sources, effectively remove indoor air pollution to form a clean and safe breathing gas state, and monitor indoor air quality anytime and anywhere. When indoor air quality is poor, the invention aims to intelligently generate gas convection in the indoor space, quickly detect and locate the area of ​​indoor air pollution, and effectively control multiple filtration and purification devices to implement intelligent gas convection to accelerate the direction of air pollution, filter and remove indoor air pollution sources, and achieve zero indoor air pollution, thus achieving a clean and safe breathing gas state. [Summary of the Invention]

[0005] This invention is a central controller for eliminating indoor air pollution. Its main purpose is to detect indoor air pollution and generate air pollution data. After processing and calculating the air pollution data with wireless communication, it can intelligently determine the nature, concentration, and location of indoor air pollution. It can then intelligently drive a fan to generate the direction of gas convection. Through physical or chemical filtration elements, it can remove indoor air pollution and create a clean and safe indoor environment.

[0006] To achieve the above objectives, a central controller for eliminating indoor air pollution is provided. This central controller is installed indoors to detect air pollution and output air pollution data. Based on the air pollution data, the central controller performs intelligent calculations to locate the area of ​​air pollution within the room. It can intelligently select and send a control command via wireless communication to multiple physical or chemical filtration devices. Each physical or chemical filtration device includes at least one fan and at least one filter element. The fan receives the control command and is driven to generate directional gas convection, allowing the air pollution to pass through the filter element and be removed, thereby eliminating indoor air pollution and creating a clean, safe-to-breath environment.

Detailed Implementation Methods

[0009] Embodiments embodying 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 be varied in different forms without departing from the scope of the invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the invention.

[0010] Please see Figure 1A The present invention is a central controller B for eliminating indoor air pollution. The central controller B is installed indoors to detect air pollution and provide air pollution data output. The central controller B performs intelligent calculations based on the air pollution data to find the area where indoor air pollution is located. It can intelligently select and send control commands via wireless communication to multiple physical filter devices C or chemical filter devices C. Each physical filter device C or chemical filter device C includes at least one fan 11 and at least one filter element 12. The fan 11 is driven by the control command to generate directional gas convection, so that air pollution is removed by passing through the filter element 12, thereby eliminating indoor air pollution and creating a clean and safe breathing gas state.

[0011] It is worth noting that the aforementioned air pollution refers to one or a combination of particulate matter, carbon monoxide, carbon dioxide, ozone, sulfur dioxide, nitrogen dioxide, lead, total volatile organic compounds, formaldehyde, bacteria, fungi, and viruses.

[0012] The central controller B includes a central processing unit 13, a communication interface 14, and a gas detection device A. The gas detection device A detects air pollution and provides air pollution data output to the central processing unit 13. The central processing unit 13 performs intelligent calculations based on the air pollution data to find the area of ​​indoor air pollution and can intelligently select to send control commands to multiple physical or chemical filter devices C through the communication interface 14.

[0013] It is worth noting that the communication interface 14 can be connected via a wired communication transmission link or via a wireless communication transmission link. The wireless communication transmission link can be one of the following: Wi-Fi module, Bluetooth module, RFID module, or near-field communication module.

[0014] It is worth noting that, please refer to Figure 2 The aforementioned central processing unit 13 performs intelligent calculations based on air pollution data. The intelligent calculations are further connected to a cloud device E to perform artificial intelligence (AI) calculations and big data comparisons to find the area of ​​the air pollution in the room. It can also intelligently select to send the control command to multiple physical filter devices C or chemical filter devices C via wireless communication through the communication interface 14.

[0015] In this specific embodiment, the central controller B can be integrated and installed on other physical or chemical filtration devices C that have a fan 11 and a filter element 12. The filtration device C can be a fresh air unit C1, an air purifier C2, an exhaust fan C3, a range hood C4, or an electric fan C5, etc. This embodiment uses the example of the central controller B being installed on the filter device C. The central controller B is installed on the filter device C. The air pollution data detected by the gas detection device A of the central controller B is intelligently calculated by the central processor 13, and further connected to the cloud device E to perform artificial intelligence (AI) calculations and big data comparisons to find the area of ​​indoor air pollution. It can also intelligently select the communication interface 14 through wireless communication to send control commands to multiple physical or chemical filtration devices C.

[0016] Additionally, it is worth noting that gas detection device A is installed within the central controller B to detect the nature and concentration of air pollution. Gas detection device A provides air pollution data output, which is then processed intelligently by the central processor 13. Furthermore, it can connect to the air pollution data outputs of multiple central controllers B (installed on different filter devices C) via cloud device E to perform artificial intelligence (AI) calculations and big data comparisons to locate the area of ​​indoor air pollution. In other words, the air pollution data provided by each gas detection device A is compared through intelligent calculations to determine the level of air pollution data, thereby estimating the area of ​​air pollution and issuing control commands via wireless communication to drive the physical or chemical filter device C.

[0017] It is worth noting that each physical filtration device C or chemical filtration device C includes at least one fan 11 and at least one filter element 12. For example... Figure 1AAs shown, the fan 11 has the function of bidirectionally conveying gas, either by drawing or supplying air. In this embodiment, the airflow path (direction indicated by the arrow) is used for illustration. The fan 11 can be installed in front of the filter element 12, or behind the filter element 12, or both (e.g., front and rear). Figure 1A As shown, the fan 11 can be designed and adjusted according to actual needs.

[0018] It is worth noting that the central processor 13 of the central controller B intelligently selects to send control commands via wireless communication through the communication interface 14 to activate the physical or chemical filter C in the area of ​​air pollution. Then, it intelligently selects to send control commands via wireless communication through the communication interface 14 to activate the remaining physical or chemical filter C, generating gas convection. This gas convection accelerates the movement of air pollution towards the physical or chemical filter C near the area of ​​air pollution, allowing the air pollution to be filtered and removed by the filter element 12, thus clearing the indoor air pollution and creating a clean and safe breathing environment. In other words, when air pollution data is output from multiple gas detection devices A connected via cloud device E, and after artificial intelligence (AI) calculation and big data comparison, the fan 11 of the physical or chemical filter device C, which is closer to the air pollution location, receives a control command and starts to drive. It first generates airflow, and then intelligently selects and sends control commands to the fans 11 of the other physical or chemical filter devices C, which are farther away from the air pollution location. They receive the control commands and start to drive, thereby generating gas convection. This gas convection accelerates the movement of air pollution towards the physical or chemical filter device C, which is closer to the air pollution location, and removes the air pollution with the filter element 12. This eliminates the air pollution in the room, creating a clean and safe breathing environment.

[0019] Furthermore, it's worth noting that "air pollution filtration zeroing" refers to filtering air pollution down to safe levels, or even removing it completely to a state of clean, breathable air. These safe air pollution levels include particulate matter (PM2.5). 2.5 The concentration of ) is less than 10 μg / m 3 The concentrations of carbon dioxide (CO2) and total volatile organic compounds (TVOC) are less than 1000 ppm, less than 0.56 ppm, less than 0.08 ppm, and less than 1500 CFU / m³. 3 Fungal count less than 1000 CFU / m 3The concentrations of sulfur dioxide, nitrogen dioxide, carbon monoxide, ozone, and lead are all less than 0.1 ppm and 0.15 μg / m³, respectively. 3 .

[0020] It is worth noting that, please refer to Figure 1BThe physical filtration device described above uses a filter element 124, which removes air pollution through physical means of blocking and adsorption. This filter element 124 is a high-efficiency filter 124a, which adsorbs chemical fumes, bacteria, dust particles, and pollen contained in the air pollution, thus achieving a filtration and purification effect. The chemical filtration device uses a chemical method to remove air pollution by coating the filter element 12 with a decomposition layer 121. This decomposition layer 121 is activated carbon 121a, which removes organic and inorganic substances from the air pollution, as well as colored and odorous substances. The decomposition layer 121 also contains a chlorine dioxide purification factor 121b, which inhibits viruses, bacteria, fungi, influenza A virus, influenza B virus, enterovirus, and norovirus in the air pollution with an inhibition rate of over 99%, helping to reduce viral cross-infection. The decomposition layer 121 also contains a herbal protective layer 121c of ginkgo and sumac, which effectively resists allergies and destroys the surface proteins of influenza viruses (e.g., H1N1). The system employs a silver ion 121d to inhibit viruses, bacteria, and fungi in introduced air pollution. The decomposition layer 121 is a zeolite 121e that removes ammonia nitrogen, heavy metals, organic pollutants, E. coli, phenol, chloroform, and anionic surfactants. The filter element 12 of this chemical filtration device, combined with a light irradiation 122, removes air pollution through a chemical process. The light irradiation 122 is a photocatalyst unit consisting of a photocatalyst 122a and an ultraviolet lamp 122b. When the photocatalyst 122a is irradiated by the ultraviolet lamp 122b, it converts light energy into electrical energy, decomposing harmful substances in the air pollution and disinfecting and sterilizing, thus achieving filtration and purification. The light irradiation 122 also includes a photoplasma unit with a nanotube 122c. Irradiating the introduced air pollution through the nanotube 122c decomposes oxygen and water molecules in the air pollution into highly oxidizing photoplasma, forming an ion stream that destroys organic molecules. This removes volatile organic compounds (VOCs) such as formaldehyde, toluene, and volatile organic compounds from the air pollution. Organic compounds (VOCs) and other gas molecules are decomposed into water and carbon dioxide, achieving filtration and purification. The filter element 12 of this chemical filtration device, combined with a decomposition unit 123, removes air pollution chemically. The decomposition unit 123 is a negative ion unit 123a, which causes positively charged particles in the introduced air pollution to attach to negatively charged particles, achieving filtration and purification. The decomposition unit 123 also includes a plasma unit 123b, which uses plasma to ionize oxygen and water molecules in the air pollution to generate cations (H+). + ) and anion (O 2-Furthermore, substances with water molecules attached to the ions adhere to the surface of viruses and bacteria. Under the action of chemical reactions, they are transformed into highly oxidizing reactive oxygen species (hydroxyl, OH groups), which take away hydrogen from the surface proteins of viruses and bacteria, oxidizing and decomposing them, thereby achieving the effect of filtering and purifying the introduced air pollution.

[0021] To understand the implementation of the method of the present invention, the structure of the gas detection device A of the central controller B of the present invention will be described in detail below.

[0022] Please see Figures 3 to 11 As shown, the gas detection device A of the present invention will be referred to as 3 below. The gas detection device 3 includes: a control circuit board 31, a gas detection body 32, a microprocessor 33, and a communicator 34. The gas detection body 32, microprocessor 33, and communicator 34 are integrated into the control circuit board 31 and electrically connected to each other. The microprocessor 33 and communicator 34 are disposed on the control circuit board 31. The microprocessor 33 controls the drive signal of the gas detection body 32 to start the detection operation. The gas detection body 32 detects the air pollution and outputs a detection signal. The microprocessor 33 receives the detection signal, processes it, and outputs air pollution data, which is then provided to the communicator 34 for wireless transmission to a connected device. The wireless transmission can be performed using one of a Wi-Fi module, a Bluetooth module, a radio frequency identification (RFID) module, or a near-field communication (NFC) module.

[0023] Please see Figures 4A to 9AAs shown, the gas detection body 32 includes a base 321, a piezoelectric actuator 322, a drive circuit board 323, a laser assembly 324, a particle sensor 325, and an outer cover 326. The base 321 has a first surface 3211, a second surface 3212, a laser setting area 3213, an air inlet groove 3214, a gas guide assembly support area 3215, and an air outlet groove 3216. The first surface 3211 and the second surface 3212 are two surfaces arranged opposite to each other. The laser assembly 324 is formed by hollowing out from the first surface 3211 towards the second surface 3212. The outer cover 326 covers the base 321 and has a side plate 3261 with an air inlet frame 3261a and an air outlet frame 3261b. The air inlet groove 3214 is recessed from the second surface 3212 and is adjacent to the laser setting area 3213. The air intake groove 3214 has an air intake port 3214a that connects to the outside of the base 321 and corresponds to the air intake frame port 3261a of the outer cover 326. The air intake groove 3214 also has light-transmitting windows 3214b that penetrate both sides of its walls, connecting to the laser setting area 3213. Therefore, the first surface 3211 of the base 321 is covered by the outer cover 326, and the second surface 3212 is covered by the drive circuit board 323, causing the air intake groove 3214 to define an air intake path.

[0024] The air guide component bearing area 3215 is formed by a recess in the second surface 3212 and is connected to the air inlet groove 3214. A vent 3215a is passed through the bottom surface, and each of the four corners of the air guide component bearing area 3215 has a positioning protrusion 3215b. The aforementioned air outlet groove 3216 is provided with an air outlet 3216a, which is correspondingly set with the air outlet frame opening 3261b of the outer cover 326. The venting groove 3216 includes a first section 3216b formed by the recess of the first surface 3211 into the vertical projection area of ​​the air guiding component support area 3215, and a second section 3216c formed by hollowing out from the first surface 3211 to the second surface 3212. The first section 3216b and the second section 3216c are connected to form a step, and the first section 3216b of the venting groove 3216 communicates with the vent hole 3215a of the air guiding component support area 3215, and the second section 3216c of the venting groove 3216 communicates with the vent outlet 3216a. Therefore, when the first surface 3211 of the base 321 is covered by the outer cover 326 and the second surface 3212 is covered by the drive circuit board 323, the venting groove 3216 and the drive circuit board 323 together define an venting path.

[0025] The aforementioned laser component 324 and particle sensor 325 are both mounted on the drive circuit board 323 and located within the base 321. To clarify the positions of the laser component 324 and particle sensor 325 relative to the base 321, the drive circuit board 323 is deliberately omitted. The laser component 324 is housed within the laser setting area 3213 of the base 321, and the particle sensor 325 is housed within the air intake groove 3214 of the base 321 and aligned with the laser component 324. Furthermore, the laser component 324 corresponds to the light-transmitting window 3214b, through which the laser emitted by the laser component 324 passes, illuminating the air intake groove 3214. The beam path emitted by the laser component 324 passes through the light-transmitting window 3214b and forms an orthogonal direction with the air intake groove 3214. The laser component 324 emits a beam that enters the air intake groove 3214 through the light-transmitting window 3214b. The gas in the air intake groove 3214 is irradiated. When the light beam comes into contact with the gas, it scatters and generates projected light spots. The particle sensor 325 is positioned in the orthogonal direction and receives the projected light spots generated by the scattering to calculate and obtain gas detection data. Additionally, a gas sensor 327 is positioned on and electrically connected to the drive circuit board 323 and housed in the air intake groove 3214 to detect air pollution entering the air intake groove 3214. In a preferred embodiment of the present invention, the gas sensor 327 is a volatile organic compound sensor, detecting carbon dioxide or total volatile organic compound gas information; or a formaldehyde sensor, detecting formaldehyde gas information; or a bacteria sensor, detecting bacteria and fungi information; or a virus sensor, detecting virus gas information.

[0026] The piezoelectric actuator 322 is housed in the square gas guide assembly support area 3215 of the base 321. Furthermore, the gas guide assembly support area 3215 communicates with the inlet groove 3214. When the piezoelectric actuator 322 is actuated, gas is drawn from the inlet groove 3214 into the piezoelectric actuator 322, and then supplied through the vent hole 3215a of the gas guide assembly support area 3215 into the outlet groove 3216. The drive circuit board 323 is sealed on the second surface 3212 of the base 321. The laser assembly 324 is disposed on the drive circuit board 323 and electrically connected. The particle sensor 325 is also disposed on the drive circuit board 323 and electrically connected. When the outer cover 326 covers the base 321, the air inlet 3261a corresponds to the air inlet 3214a of the base 321, and the air outlet 3261b corresponds to the air outlet 3216a of the base 321.

[0027] The piezoelectric actuator 322 includes an air jet plate 3221, a cavity frame 3222, a co-actuator 3223, an insulating frame 3224, and a conductive frame 3225. The air jet plate 3221 is made of a flexible material and has a suspension plate 3221a and a hollow hole 3221b. The suspension plate 3221a is a sheet-like structure that bends and vibrates, and its shape and size correspond to the inner edge of the air-guiding component bearing area 3215. The hollow hole 3221b penetrates the center of the suspension plate 3221a to allow gas flow. In a preferred embodiment of the invention, the shape of the suspension plate 3221a can be square, graphic, elliptical, triangular, or polygonal.

[0028] The aforementioned cavity frame 3222 is stacked on the jet orifice plate 3221, and its appearance corresponds to that of the jet orifice plate 3221. An actuator 3223 is stacked on the cavity frame 3222, defining a resonant chamber 3226 between itself, the cavity frame 3222, and the suspension plate 3221a. An insulating frame 3224 is stacked on the actuator 3223, and its appearance is similar to that of the cavity frame 3222. A conductive frame 3225 is stacked on the insulating frame 3224, and its appearance is similar to that of the insulating frame 3224. The conductive frame 3225 has a conductive pin 3225a and a conductive electrode 3225b, wherein the conductive pin 3225a extends outward from the outer edge of the conductive frame 3225, and the conductive electrode 3225b extends inward from the inner edge of the conductive frame 3225. Furthermore, the actuator 3223 further includes a piezoelectric carrier plate 3223a, an adjusting resonance plate 3223b, and a piezoelectric plate 3223c. The piezoelectric carrier plate 3223a is stacked on the cavity frame 3222. The adjusting resonance plate 3223b is stacked on the piezoelectric carrier plate 3223a. The piezoelectric plate 3223c is stacked on the adjusting resonance plate 3223b. The adjusting resonance plate 3223b and the piezoelectric plate 3223c are housed within an insulating frame 3224. The piezoelectric plate 3223c is electrically connected to the conductive plate 3223c by the conductive electrode 3225b of the conductive frame 3225. In a preferred embodiment of the present invention, both the piezoelectric carrier plate 3223a and the adjusting resonance plate 3223b are made of conductive materials. The piezoelectric carrier plate 3223a has a piezoelectric pin 3223d, which is connected to the drive circuit (not shown) on the drive circuit board 323 via a conductive pin 3225a to receive drive signals (which may be drive frequency and drive voltage). The drive signal forms a circuit through the piezoelectric pin 3223d, the piezoelectric carrier plate 3223a, the adjusting resonant plate 3223b, the piezoelectric plate 3223c, the conductive electrode 3225b, the conductive frame 3225, and the conductive pin 3225a. The insulating frame 3224 isolates the conductive frame 3225 from the actuator 3223 to prevent short circuits, allowing the drive signal to be transmitted to the piezoelectric plate 3223c. After receiving the drive signal, the piezoelectric plate 3223c deforms due to the piezoelectric effect, further driving the piezoelectric carrier plate 3223a and the adjusting resonant plate 3223b to reciprocate bending vibrations.

[0029] To further explain, the adjusting resonant plate 3223b is located between the piezoelectric plate 3223c and the piezoelectric carrier plate 3223a, acting as a buffer between the two, and can adjust the vibration frequency of the piezoelectric carrier plate 3223a. Basically, the thickness of the adjusting resonant plate 3223b is greater than that of the piezoelectric carrier plate 3223a, and the vibration frequency of the actuator 3223 is adjusted by changing the thickness of the adjusting resonant plate 3223b.

[0030] Please refer to the following: Figure 7A , Figure 7B , Figure 8A , Figure 8Band Figure 9A As shown, the jet nozzle 3221, cavity frame 3222, actuator 3223, insulating frame 3224, and conductive frame 3225 are stacked sequentially and positioned within the air guide assembly support area 3215, causing the piezoelectric actuator 322 to be positioned within the air guide assembly support area 3215. The piezoelectric actuator 322 defines a gap 3221c between the suspension plate 3221a and the inner edge of the air guide assembly support area 3215, allowing gas to flow. The jet nozzle 3221 and the bottom surface of the air guide assembly support area 3215 form an airflow chamber 3227. The airflow chamber 3227 is connected to the resonant chamber 3226 between the actuator 3223, the cavity frame 3222, and the suspension plate 3221a through the hollow hole 3221b of the jet orifice 3221. By making the vibration frequency of the gas in the resonant chamber 3226 close to that of the suspension plate 3221a, the resonant chamber 3226 and the suspension plate 3221a can generate a Helmholtz resonance effect, thereby improving the gas transmission efficiency. When the piezoelectric plate 3223c moves away from the bottom surface of the air guide assembly bearing area 3215, the piezoelectric plate 3223c drives the suspension plate 3221a of the jet nozzle plate 3221 to move away from the bottom surface of the air guide assembly bearing area 3215, causing the volume of the airflow chamber 3227 to expand rapidly, the internal pressure drops and a negative pressure is generated, which attracts the gas outside the piezoelectric actuator 322 to flow in through the gap 3221c and enter the resonant chamber 3226 through the hollow hole 3221b, increasing the air pressure in the resonant chamber 3226 and thus generating a pressure gradient. When the piezoelectric plate 3223c drives the suspension plate 3221a of the jet nozzle plate 3221 to move toward the bottom surface of the air guide assembly support area 3215, the gas in the resonant chamber 3226 flows out rapidly through the hollow hole 3221b, compresses the gas in the airflow chamber 3227, and causes the converged gas to be ejected rapidly and in large quantities into the vent hole 3215a of the air guide assembly support area 3215 in an ideal gas state close to Bernoulli's law.

[0031] By repeating Figure 9B and Figure 9CAs shown in the diagram, the piezoelectric plate 3223c vibrates reciprocally. Based on the principle of inertia, the gas pressure inside the resonant chamber 3226 after exhaust is lower than the equilibrium pressure, which guides the gas to re-enter the resonant chamber 3226. This controls the vibration frequency of the gas in the resonant chamber 3226 to be similar to the vibration frequency of the piezoelectric plate 3223c, thereby generating the Helmholtz resonance effect and achieving high-speed and large-volume gas transmission. The gas enters through the air inlet 3261a of the outer cover 326, enters the air inlet groove 3214 of the base 321 through the air inlet 3214a, and flows to the position of the particle sensor 325. Furthermore, the piezoelectric actuator 322 continuously drives the intake gas, facilitating the rapid and stable flow of external gas. The gas passes above the particle sensor 325. At this time, the laser component 324 emits a beam that enters the intake groove 3214 through the light-transmitting window 3214b. The intake groove 3214 passes above the particle sensor 325. When the beam from the particle sensor 325 irradiates the suspended particles in the gas, scattering and projection light spots are generated. The particle sensor 325 receives the projected light spots generated by the scattering and calculates to obtain information such as the particle size and concentration of the suspended particles in the gas. The gas above the particle sensor 325 is also continuously driven by the piezoelectric actuator 322 and guided into the vent 3215a of the gas guide component bearing area 3215, entering the outlet groove 3216. Finally, when the gas enters the outlet groove 3216, the gas is continuously supplied into the outlet groove 3216 by the piezoelectric actuator 322. Therefore, the gas in the outlet groove 3216 is pushed and discharged to the outside through the outlet port 3216a and the outlet frame port 3261b.

[0032] The gas detection device A of the central controller B 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 detection device A of the central controller B of the present invention further includes a gas sensor 327, which is positioned and electrically connected to the drive circuit board 323 and housed in the gas outlet groove 3216 to detect the concentration or characteristics of volatile organic compounds contained in the gas exiting the gas outlet path.
