[0006] Embodiments embodying the features of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different forms without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0007] Please refer to Figures 1A, 1B, and 1C. This invention provides an intelligent networked air purifier, comprising a main body 1, at least one filter module 2, a host drive controller 3, and at least one gas detection module 4. It is worth noting that in this embodiment, there is one set of filter modules 2 and one set of gas detection modules 4, but this is not a limitation.

[0008] The aforementioned main body 1 is provided with an airflow path (as indicated by the arrow) that is a ventilation method with parallel openings on both sides and a vertical opening. The top surface of the main body 1 is provided with at least one filter slot 11. The filter module 2 is installed in the airflow path inside the main body 1 and includes a blower 21 and a filter cleaning component 22. The filter slot 11 is used for the filter cleaning component 22 to be inserted into the airflow path. The blower 21 is set in the airflow path to form a guided airflow with parallel air intake on both sides and a vertical opening for exhaust, thereby purifying and filtering the air.

[0009] The aforementioned host drive controller 3 controls the start or stop of the air guide fan 21, and dynamically adjusts the operating frequency and output air volume. The gas detection module 4 is electrically connected to the host drive controller 3 for control. The gas detection module 4 detects humidity, temperature and air pollution in the air and outputs detection data. The detection data is transmitted to a networked cloud computing service device 5 through Internet of Things communication. The networked cloud computing service device 5 adjusts the host drive controller 3 in real time to control the start and stop of the air guide fan 21, and dynamically adjusts the operating frequency and output air volume of the air guide fan 21.

[0010] 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. The Internet of Things (IoT) communication is a wireless communication method, providing wireless communication with the networked cloud computing service device 5. This wireless communication can be one of a Wi-Fi module, a Bluetooth module, a radio frequency identification (RFID) module, or a near-field communication (NFC) module; alternatively, the IoT communication can be a wired communication method, providing wired communication with the networked cloud computing service device 5. It is worth noting that the aforementioned fan 21 can be an armature-type or centrifugal fan, but is not limited thereto. Any fan 21 capable of generating airflow is an extension of the embodiments of this case. The clean air delivery rate (CADR) output by the air guide fan 21 is 200 m³ / h or higher; or, the clean air delivery rate (CADR) output by the air guide fan 21 is 2400~10200 m³ / h, for example, the clean air delivery rate (CADR) of the air guide fan 21 can be 2400 CADR, 3200 CADR, 4000 CADR, 4800 CADR, 5600 CADR, 6400 CADR, 7200 CADR, 8000 CADR, 8800 CADR, 9600 CADR, 10200 CADR; or, the clean air delivery rate (CADR) output by the air guide fan 21 is 20000~40000 m³ / h, for example, the clean air delivery rate (CADR) of the air guide fan 21 can be 20000 CADR, 30000 CADR, 40000 CADR.

[0011] As shown in Figure 3, the gas detection module 4 includes a control circuit board 41 and a gas detection body 42. The gas detection body 42 detects humidity, temperature and air pollution and outputs detection data. The control circuit board 41 collects, calculates and analyzes the detection data and outputs a serial communication (IIC) signal input. The networked cloud computing service device 5 receives and analyzes the detection data in real time and outputs a universal asynchronous transceiver (UART) signal and a universal input and output (GPI / O) signal to the host drive controller 3.

[0012] The aforementioned control circuit board 41 is embedded on the top surface of the main body 1 and electrically connected to the host drive controller 3 for control. The control circuit board 41 is also connected to external components or devices via at least one connection interface 412. In this embodiment, the control circuit board 41 has a plurality of connection interfaces 412, which are respectively connected to the gas detection main body 42, the host drive controller 3, and a wired communication port 43. However, this is not a limitation; in specific implementations, the control circuit board 41 can select one connection interface 412 to connect to the gas detection main body 42, the host drive controller 3, and the wired communication port 43 respectively. The control circuit board 41 includes a power converter 411, which provides a DC voltage divider and modulated output of a required DC voltage, and supplies this required DC voltage to the gas detection unit 42 and the host drive controller 3 via the connection interface 412 for startup operation; the control circuit board 41 also includes a microcontroller (MCU) 413, which connects to the gas detection unit 42 via the connection interface 412 to form a serial communication (IIC) signal input for processing and analyzing the detection data, and connects to the connection interface 412 to output a universal asynchronous transceiver (UART) signal and a universal input / output (GPIO) signal. The I / O signal is provided to the host drive controller 3 for regulation; and the control circuit board 41 includes a wireless communicator 414, which receives detection data and wirelessly transmits it to the networked cloud computing service device 5. The networked cloud computing service device 5 collects, analyzes and monitors the detection data in real time and intelligently selects control commands. The wireless communicator 414 receives and transmits the data to the microcontroller (MCU) 413, which outputs a universal asynchronous transceiver (UART) signal and a universal input and output (GP I / O) signal to provide regulation to the host drive controller 3, so as to control the host drive controller 3 to start and regulate the operation of the fan 21 and dynamically adjust the operating frequency and output air volume. Furthermore, the intelligent networked air purifier further includes a wired communication port 43, which is electrically connected to the control circuit board 41 via a connection interface 412. This allows for external wired communication transmission, transmitting received detection data to the networked cloud computing service device 5. The device collects and analyzes real-time monitoring data and intelligently selects control commands, which are received via the wired communication port 43 and transmitted to the microcontroller (MCU) 413. The MCU outputs a Universal Asynchronous Receiver / Transmitter (UART) signal and a Universal Input / Output (GPI / O) signal, providing control to the host drive controller 3. This control enables the host drive controller 3 to activate and regulate the operation of the fan 21 and dynamically adjust its operating frequency and output airflow. Notably, the wired communication port 43 is an RS485 port, communicating with the networked cloud computing service device 5 via a wired connection.

[0013] Please refer to Figures 4A, 4B, 5, 6A to 6C, 7A and 7B. The gas detection body 42 mentioned above includes a base 421, a piezoelectric actuator 422, a drive circuit board 423, a laser assembly 424, a particle sensor 425, an outer cover 426 and a gas sensor 427.

[0014] The aforementioned base 421 has a laser mounting area 4211, an air inlet groove 4212, an air guide component support area 4213, and an air outlet groove 4214. The air inlet groove 4212 has an air inlet port 4215 and a light-transmitting window 4216 penetrating through each of its two side walls, communicating with the laser mounting area 4211. The air guide component support area 4213 is connected to the air inlet groove 4212 and has a vent hole 4217 penetrating through its bottom surface. The air outlet groove 4214 is connected to the vent hole 4217 and has an air outlet 4218. The outer cover 426 covers the base 421 and has a side plate 4261. The side plate 4261 is provided with an air inlet 4262 and an air outlet 4263. The air inlet 4262 corresponds to the air inlet 4215 of the base 421, and the air outlet 4263 corresponds to the air outlet 4218 of the base 421.

[0015] The aforementioned laser assembly 424, particle sensor 425, and gas sensor 427 are all integrally electrically connected on the drive circuit board 423, and are located within the base 421 when the drive circuit board 423 is closed. To clearly illustrate the positions of the laser assembly 424 and particle sensor 425 relative to the base 421, the drive circuit board 423 is deliberately omitted. The laser assembly 424 is housed within the laser mounting area 4211 of the base 421, and the particle sensor 425 is housed within the air intake groove 4212 of the base 421, aligned with the laser assembly 424. Furthermore, the laser assembly 424 corresponds to the light-transmitting window 4216, through which the laser light emitted by the laser assembly 424 passes, illuminating the air intake groove 4212. The beam path emitted by the laser assembly 424 passes through the light-transmitting window 4216 and forms an orthogonal direction with the air intake groove 4212. The laser assembly 424 emits a light beam that enters the air intake groove 4212 through the light-transmitting window 4216. The beam illuminates the gas within the groove, illuminating the gas containing the emitted light. When the beam contacts suspended particles in the gas, it scatters, generating projected light spots. This positions the particle sensor 425 in an orthogonal direction, allowing it to receive and calculate the projected light spots to obtain the gas detection data. Notably, the light source emitted by the laser assembly 424 is a parallel light source that passes through the light-transmitting window 4216.

[0016] The aforementioned gas sensor 427 is positioned and housed in the gas outlet groove 4214 for detecting gas contamination introduced into the gas outlet groove 4214. In a preferred embodiment of the present invention, the particulate sensor 425 detects suspended particulates and outputs detection data, and the gas sensor 427 is a volatile organic compound sensor that detects carbon dioxide or total volatile organic compounds and outputs detection data; or a formaldehyde sensor that detects formaldehyde gas and outputs detection data; or a bacteria sensor that detects bacteria or fungi and outputs detection data; or a virus sensor that detects virus gas and outputs detection data; or a temperature and humidity sensor that detects the temperature and humidity of the gas and outputs detection data.

[0017] Please refer to Figure 7. The piezoelectric actuator 422 described above is housed in the air guide assembly support area 4213 of the base 421. The air guide assembly support area 4213 communicates with the air inlet groove 4212. When the drive circuit board 423 is sealed inside the base 421 and the outer cover 426 covers the outside of the base 421, the air inlet frame 4262 corresponds to the air inlet port 4215 of the base 421, defining an air inlet path, and the air outlet frame 4263 corresponds to the air outlet port 4218 of the base 421, jointly defining an air outlet path. At this time, the piezoelectric actuator 42... 2. During operation, gas is drawn from the inlet groove 4212 into the piezoelectric actuator 422, and then supplied through the vent 4217 of the air guide assembly bearing area 4213 into the outlet groove 4214. Finally, after the gas enters the outlet groove 4214, the piezoelectric actuator 422 continuously supplies gas from the inlet path into the outlet groove 4214. Therefore, the gas in the outlet groove 4214 is pushed to the outlet path and discharged to the outside through the outlet port 4218 and the outlet frame port 4263, realizing high-speed and large-volume gas transmission.

[0018] Having understood the above description of the gas detection body 42 structure, the following is a detailed explanation of the piezoelectric actuator 422 structure.

[0019] Please refer to Figures 8A and 8B. The piezoelectric actuator 422 includes an air jet plate 4221, a cavity frame 4222, an actuator 4223, an insulating frame 4224, and a conductive frame 4225. The air jet plate 4221 is made of a flexible material and has a suspension plate 4221a and a hollow hole 4221b. The suspension plate 4221a 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 4213. The hollow hole 4221b penetrates the center of the suspension plate 4221a to allow gas flow. In a preferred embodiment of the invention, the shape of the suspension plate 4221a can be square, graphic, elliptical, triangular, or polygonal.

[0020] Furthermore, the aforementioned cavity frame 4222 is stacked on the jet orifice plate 4221, and its appearance corresponds to that of the jet orifice plate 4221. An actuator 4223 is stacked on the cavity frame 4222, defining a resonant chamber 4226 between itself, the jet orifice plate 4221, and the suspension plate 4221a. An insulating frame 4224 is stacked on the actuator 4223, and its appearance is similar to that of the cavity frame 4222. A conductive frame 4225 is stacked on the insulating frame 4224, and its appearance is similar to that of the insulating frame 4224. The conductive frame 4225 has a conductive pin 4225a and a conductive electrode 4225b extending outward from the outer edge of the conductive pin 4225a, and the conductive electrode 4225b extending inward from the inner edge of the conductive frame 4225.

[0021] Furthermore, the actuator 4223 further includes a piezoelectric carrier plate 4223a, an adjusting resonance plate 4223b, and a piezoelectric plate 4223c. The piezoelectric carrier plate 4223a is stacked on the cavity frame 4222. The adjusting resonance plate 4223b is stacked on the piezoelectric carrier plate 4223a. The piezoelectric plate 4223c is stacked on the adjusting resonance plate 4223b. The adjusting resonance plate 4223b and the piezoelectric plate 4223c are housed within an insulating frame 4224. The piezoelectric plate 4223c is electrically connected to the conductive plate 4223c by the conductive electrode 4225b of the conductive frame 4225. In a preferred embodiment of the present invention, both the piezoelectric carrier plate 4223a and the adjusting resonance plate 4223b are made of conductive materials. The piezoelectric carrier plate 4223a has a piezoelectric pin 4223d, which is connected to the drive circuit (not shown) on the drive circuit board 423 via a conductive pin 4225a to receive drive signals (which may be drive frequency and drive voltage). The drive signal forms a circuit through the piezoelectric pin 4223d, the piezoelectric carrier plate 4223a, the adjusting resonant plate 4223b, the piezoelectric plate 4223c, the conductive electrode 4225b, the conductive frame 4225, and the conductive pin 4225a. The insulating frame 4224 isolates the conductive frame 4225 from the actuator 4223 to prevent short circuits, allowing the drive signal to be transmitted to the piezoelectric plate 4223c. After receiving the drive signal, the piezoelectric plate 4223c deforms due to the piezoelectric effect, further driving the piezoelectric carrier plate 4223a and the adjusting resonant plate 4223b to produce reciprocating bending vibrations.

[0022] To further explain, the adjusting resonant plate 4223b is located between the piezoelectric plate 4223c and the piezoelectric carrier plate 4223a, acting as a buffer between the two, and can adjust the vibration frequency of the piezoelectric carrier plate 4223a. Basically, the thickness of the adjusting resonant plate 4223b is greater than that of the piezoelectric carrier plate 4223a, and the vibration frequency of the actuator 4223 is adjusted by changing the thickness of the adjusting resonant plate 4223b. The jet nozzle plate 4221, the cavity frame 4222, the actuator 4223, the insulating frame 4224, and the conductive frame 4225 are stacked sequentially and positioned within the air guiding assembly support area 4213, causing the piezoelectric actuator 422 to be positioned within the air guiding assembly support area 4213. The piezoelectric actuator 422 defines a gap 4221c between the suspension plate 4221a and the inner edge of the air guiding assembly support area 4213 for gas flow.

[0023] An airflow chamber 4227 is formed between the jet nozzle 4221 and the bottom surface of the air guide assembly support area 4213. The airflow chamber 4227 is connected to the resonant chamber 4226 between the actuator 4223, the jet nozzle 4221, and the suspension plate 4221a through the hollow hole 4221b of the jet nozzle 4221. By making the vibration frequency of the gas in the resonant chamber 4226 close to that of the suspension plate 4221a, the resonant chamber 4226 and the suspension plate 4221a can generate a Helmholtz resonance effect, thereby improving the gas transmission efficiency. When the piezoelectric plate 4223c moves away from the bottom surface of the air guide assembly bearing area 4213, the piezoelectric plate 4223c drives the suspension plate 4221a of the jet nozzle plate 4221 to move away from the bottom surface of the air guide assembly bearing area 4213, causing the volume of the airflow chamber 4227 to expand rapidly, the internal pressure drops and a negative pressure is generated, which attracts the gas outside the piezoelectric actuator 422 to flow in through the gap 4221c, and enter the resonant chamber 4226 through the hollow hole 4221b, increasing the air pressure in the resonant chamber 4226 and thus generating a pressure gradient. When the piezoelectric plate 4223c drives the suspension plate 4221a of the jet nozzle plate 4221 to move toward the bottom surface of the air guide assembly bearing area 4213, the gas in the resonant chamber 4226 flows out rapidly through the hollow hole 4221b, compressing the gas in the airflow chamber 4227, and causing the converged gas to be ejected rapidly and in large quantities through the vent 4217 of the air guide assembly bearing area 4213 in an ideal gas state close to Bernoulli's law.

[0024] By repeating the actions shown in Figures 9B and 9C, the piezoelectric plate 4223c vibrates reciprocally. According to the principle of inertia, the gas pressure inside the resonant chamber 4226 after exhaust is lower than the equilibrium gas pressure, which will guide the gas to re-enter the resonant chamber 4226. In this way, the vibration frequency of the gas in the resonant chamber 4226 is controlled to be similar to the vibration frequency of the piezoelectric plate 4223c, so as to generate the Helmholtz resonance effect and realize the high-speed and large-volume transmission of gas.

[0025] Please refer to Figures 10A to 10C. The gas enters through the air inlet 4262 of the outer cover 426, enters the air inlet groove 4212 of the base 421 through the air inlet 4215, and flows to the position of the particle sensor 425. Furthermore, the piezoelectric actuator 422 continuously draws in gas from the intake path to facilitate rapid and stable flow of external gas. The gas passes above the particle sensor 425. At this time, the laser assembly 424 emits a beam of light through the light-transmitting window 4216 into the intake groove 4212. The intake groove 4212 passes above the particle sensor 425. When the beam of light from the particle sensor 425 irradiates suspended particles in the gas, scattering and projection of light spots occur. The particle sensor 425 receives the projected light spots generated by the scattering and performs calculations to obtain information such as the particle size and quantity of suspended particles in the gas. The gas above the particle sensor 425 is also continuously driven by the piezoelectric actuator 422 and guided into the vent 4217 of the air guide assembly bearing area 4213, entering the outlet groove 4214. Finally, when the gas enters the outlet groove 4214, the gas is continuously supplied into the outlet groove 4214 by the piezoelectric actuator 422. Therefore, the gas in the outlet groove 4214 is pushed and discharged to the outside through the outlet port 4218 and the outlet frame port 4263, realizing high-speed and large-volume gas transmission.

[0026] After understanding the overall structure and architecture of the intelligent networked air purifier of this invention, it is clear that the built-in gas detection module 4 of the intelligent networked air purifier has cloud connectivity capabilities. Combined with the intelligent system implemented in the indoor air purification network mechanism, it can upload all air pollution detection data to the networked cloud computing service device 5. Users can remotely view the air quality of the indoor environment, and in particular, it can monitor and automatically adjust purification efficiency in real time, saving energy and reducing consumption, thereby improving air comfort and maintaining optimal indoor air quality. As shown in Figure 11, the networked cloud computing service device 5 includes a wireless network cloud computing service module 51, a cloud control service unit 52, a device management unit 53, an application unit 54, and an AI intelligent control platform 55.The wireless network cloud computing service module 51 receives data detected by the gas detection module 4 of the smart network air purifier and transmits control commands. The wireless network cloud computing service module 51 receives the detection data and transmits it to the cloud control service unit 52 for storage, forming an air pollution big data database. It performs intelligent calculations and compares the data with the database, then sends control commands to the wireless network cloud computing service module 51, which in turn transmits the control start operation to the gas detection module 4 of the smart network air purifier. The device management unit 53 then... The wireless network cloud computing service module 51 receives communication information from the gas detection module 4 of the smart network air purifier for user login management and device binding. It also provides management information such as maintenance and management of the smart network air purifier, automated anomaly detection, analysis, handling and improvement, control and inspection to ensure cleanliness requirements are met, customer feedback, and hardware and software technology improvement correction mechanisms. This information is provided to the application unit for system control and management. The application unit 54 also displays and notifies users of the air quality detection data obtained from the cloud control service unit 52, allowing users to... The user can use a mobile phone or communication device to understand the real-time status of air pollution removal, and control the operation of the indoor air purification network intelligent system through the application unit 54 of the mobile phone or communication device; and the AI ​​intelligent control platform 55 collects and analyzes the air quality detection data obtained from real-time monitoring and intelligently selects control commands to be received by the gas detection module 4 of the intelligent network air purifier, so as to control the main drive controller 3 to start the operation of the guide fan 21 and dynamically adjust the operating frequency and output air volume of the guide fan 21; that is, intelligently judges the control commands issued to the main drive controller 3 to start the operation of the guide fan 21 and dynamically adjust the operating frequency and output air volume of the guide fan 21. The operation of the automatic air guide fan 21 and its dynamic adjustment of operating frequency and output air volume are as follows: As the gas detection data exceeds the safe detection value, the air volume of the air guide fan 21 is increased, automatically activating the enhanced purification mode; conversely, as the gas detection data approaches the safe detection value, the air volume of the air guide fan 21 is decreased. Based on the collected and analyzed real-time monitoring data, the operating frequency of the air guide fan 21 is dynamically adjusted, automatically switching to a low-energy consumption mode and reducing airflow and noise. It even stops operating when the indoor air quality approaches zero, reducing unnecessary energy consumption.

[0027] Of course, as shown in Figure 2, the filtration and purification component 22 of the present invention can be a combination of various embodiments. In some specific embodiments, the filtration and purification component 22 can be a filter 22a, which can be a filter with an MREV of 8 or higher (minimum filtration efficiency value), or the filter 22a can be a high-efficiency particulate air (HEPA) filter. The filter is HEPA-grade, adsorbing chemical fumes, bacteria, dust particles, and pollen contained in air pollution, thus achieving a filtration and purification effect. It is worth noting that the HEPA filter in this case is HEPA 10 or higher, with a dust holding capacity greater than 12000mg, or the filter 22a is a more efficient LPA14 filter, further improving filtration efficiency and meeting higher cleanliness requirements. In some specific embodiments, the filter cleaning component 22 can be further combined with physical or chemical materials to provide a sterilization effect on the air pollution. The airflow path of the fan 21 is in the direction shown by the arrow. The filter cleaning component 22 combines a chemical method of passing through a decomposition layer to sterilize and remove air pollution. The decomposition layer can be activated carbon 22b, removing organic and inorganic substances from the air pollution, as well as colored and odorous substances. It is worth noting that the formaldehyde absorption capacity of the activated carbon 22b in this case is greater than 1500mg.In some embodiments, the filter and purification component 22 can also be combined with a light-irradiated chemical method to sterilize and remove air pollution. The light irradiation is a photocatalyst unit consisting of a photocatalyst 22c and an ultraviolet lamp 22d, to further improve the removal efficiency of air pollutants and allergens. When the photocatalyst 22c is irradiated by the ultraviolet lamp 22d, it can convert light energy into electrical energy, decompose harmful substances in the air pollution, and disinfect and sterilize to achieve a filtration and sterilization effect. It is worth noting that the power of the ultraviolet lamp 22d in this case is above 120mw. The light irradiation can be a photoplasma unit consisting of a nano-light tube 22e. When the air pollution is irradiated by the nano-light tube 22e, the oxygen and water molecules in the air pollution are decomposed into highly oxidizing photoplasma, forming an ion gas flow that destroys organic molecules, thereby removing volatile organic compounds (VOCs) such as formaldehyde, toluene, and volatile organic compounds from the air pollution. VOCs and other gas molecules are decomposed into water and carbon dioxide to further improve the removal efficiency of air pollutants and allergens, achieving the effect of filtration and sterilization. In some embodiments, the filter and purification component 22 can also be combined with a decomposition unit to chemically remove air pollutants through sterilization. The decomposition unit can be a negative ion unit 22f, which causes the particles contained in the introduced air pollutants to attach to the negatively charged particles, thereby further improving the removal efficiency of air pollutants and allergens, achieving the effect of filtration and sterilization of the introduced air pollutants. The decomposition unit can be a plasma ion unit 22g, through which oxygen molecules and water molecules contained in the air pollutants are ionized to generate cations (H+) and anions (O+). 2-), and substances with water molecules attached to the ions, after adhering to the surface of viruses and bacteria, will be transformed into highly oxidizing reactive oxygen species (hydroxyl, OH groups) under the action of chemical reactions. This will remove hydrogen from the surface proteins of viruses and bacteria, oxidizing and decomposing them. This process can decompose and eliminate pollutants, allergens, and microorganisms in the air, improving air cleanliness and achieving the effect of filtering and sterilizing introduced air pollution. The decomposition unit can be a 22-hour electrostatic filtration unit, using electrostatic force to capture and remove suspended particles in the air (such as dust, pollen, bacteria, and other pollutants).

[0028] As explained above, the intelligent networked air purifier provided by this invention has a built-in gas detection module 4 with cloud connectivity for real-time monitoring and adjustment. Combined with the networked cloud computing service device 5 of the intelligent indoor air purification network system, it has the following effects: real-time monitoring and adjustment. The built-in gas detection module 4 can monitor the humidity, temperature and air pollution in the indoor air in real time, and transmit the detection data to the networked cloud computing service device 5 through Internet of Things (wireless or wired network) communication. The AI ​​intelligent control platform 55 controls the operation of the duct fan 21 and dynamically adjusts the operation frequency and output air volume to improve the purification efficiency based on the collected and analyzed real-time monitoring detection data. That is, the higher the gas detection data is above the safe detection value, the greater the adjustment of the airflow of the guide fan 21; conversely, the closer the gas detection data is to the safe detection value, the smaller the adjustment of the airflow of the guide fan 21. Intelligent cloud connectivity: the gas detection module 4 has cloud connectivity capabilities, allowing all air pollution detection data to be uploaded to the networked cloud computing service device 5, enabling users to remotely view the air quality of the indoor environment. Multiple filtration technologies: the filtration and purification components 22 of the filter module 2 can be combined with activated carbon, high-efficiency filters, electrostatic filters, photocatalyst units, negative ion units, or plasma units to achieve optimal filtration effects based on different pollution sources. Multi-device collaborative operation: if multiple intelligent networked air purifiers are configured in the same indoor space, the networked cloud computing service device 5 can adjust the airflow based on the air pollution detection data of each device. The entire system operates as a collaborative air purification network, achieving optimal air quality across the entire area. The networked cloud computing service device 5 can detect different data from the gas detection modules 4 of the smart networked air purifiers in different locations. The networked cloud computing service device 5 will also transmit control signals to the corresponding smart networked air purifiers based on different levels of air quality. The networked cloud computing service device 5 controls the start-up operation of the fan 21 and the adjustment of the airflow. It is energy-saving and low-consumption. When the indoor and outdoor humidity is similar or the air quality meets the standards, the networked cloud computing service device 5 will dynamically adjust the operating frequency of the fan based on the collected and analyzed real-time monitoring detection data, automatically switch to a low-energy consumption mode, and reduce airflow and noise. It will even stop operating when the indoor air quality approaches zero to reduce unnecessary energy consumption.

[0029] In summary, this invention is an intelligent networked air purifier. The device has a built-in filter module 2 and a gas detection module 4 to detect air pollution in real time. In addition, the gas detection module 4 has cloud connectivity, which facilitates remote monitoring and operation by users. It transmits air pollution detection data to a networked cloud computing service device 5 through Internet of Things communication (wireless or wired). The networked cloud computing service device 5 intelligently selects a control command based on the collected and analyzed real-time monitoring air pollution detection data and transmits it to the gas detection module 4 to modulate the start of the fan 21 and dynamically adjust the operating frequency and output air volume to improve purification efficiency. Furthermore, it is integrated with an intelligent networked indoor air purification system to form a complete real-time processing system, which has great industrial practical value.
