[0006] Embodiments embodying the features of the present invention will be described in detail in the following description. The present invention can be modified in various ways in different embodiments, none of which will depart from the scope of the invention, and the description and drawings are used for illustrative purposes only and are not intended to limit the invention.

[0007] Refer to FIGS. 1A, 1B, 1C, 1D and 1E. The present invention provides a network-connected smart fresh air cleaner comprising a main body 1, at least one filter module 2, a host drive controller 3, and at least one gas detection module 4. In particular, in this embodiment, one set each of the filter module 2 and the gas detection module 4 are provided, but the present invention is not limited thereto.

[0008] The main body 1 is provided with an air guide path L (indicated by the arrow) consisting of parallel openings on both sides and one vertical opening that connects them. The top surface of the main body 1 is also provided with at least one filter slot 11. As shown in Figures 1A and 1E, a ventilation channel 12 is attached to the outside of the main body 1, and the other end of the ventilation channel 12 has a cover plate 13 that is positioned and sealed by the window W, allowing the ventilation channel 12 to guide air from the outdoor space B. The filter module 2 is installed in the air guide path L inside the main body 1 and includes a fan 21 and a filter unit 22. The filter unit 22 is inserted into the air guide path L via the filter slot 11, and the fan 21 is also located in the air guide path L, forming an induced airflow that draws in air from both parallel directions and exhausts it through the vertical opening for purification and filtration. The host drive controller 3 controls the on / off state of the fan 21 and dynamically adjusts the operating frequency and output airflow of the fan 21. Furthermore, the gas detection module 4 is electrically connected to the host drive controller 3. The gas detection module 4 detects humidity, temperature, and air pollution in the air, outputs detection data, and transmits the detection data to the network-connected cloud computing service device 5 via the Internet of Things communication. The network-connected cloud computing service device 5 controls the host drive controller 3 in real time, turning the air guide fan 21 on and off, and dynamically adjusting the operating frequency and output airflow of the air guide fan 21. Air from the outdoor space B enters through the ventilation channel 12, is guided by the air guide fan 21, filtered while passing through the filter unit 22, and then enters the indoor space A to achieve gas exchange, maintaining a balance in carbon dioxide (CO2) air quality detection data between the indoor space A and the outdoor space B.

[0009] The air pollution refers to any one or a combination of the following: suspended 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 communication is wireless communication that connects wirelessly to the network-connected cloud computing service device 5. This wireless communication may be any one of the following: a Wi-Fi module, a Bluetooth® module, a radio frequency identification module, or a short-range communication module. Alternatively, the Internet of Things communication may be wired communication that connects wired to the network-connected cloud computing service device 5. The air guide fan 21 may be an armature type or a centrifugal type air guide fan, but is not limited to these. Any air guide fan 21 capable of creating airflow is included in the embodiments of the present invention. The clean air delivery rate (CADR) output by the air guide fan 21 is 200 m³. 3 It is 2400m / h or more. Alternatively, the clean air delivery rate (CADR) output by the air guide fan 21 is 2400m 3 / h~10200m 3 / h, and for example, the Clean Air Delivery Rate (CADR) of the air guide fan 21 may be 2400 CADR, 3200 CADR, 4000 CADR, 4800 CADR, 5600 CADR, 6400 CADR, 7200 CADR, 8000 CADR, 8800 CADR, 9600 CADR, and 10200 CADR. Alternatively, the Clean Air Delivery Rate (CADR) output by the air guide fan 21 may be 20000m 3 / h~40000m 3 The value is / h, and for example, the clean air supply rate (CADR) of the air guide fan 21 may be 20,000 CADR, 30,000 CADR, or 40,000 CADR.

[0010] Refer to Figure 3. The gas detection module 4 comprises a control circuit board 41 and a gas detection main unit 42. The gas detection main unit 42 detects humidity, temperature, and air pollution and outputs detection data. The control circuit board 41 collects, calculates, analyzes, and outputs the detection data to form a serial communication (IIC) signal as input. The network-connected cloud computing service device 5 receives and analyzes the detection data in real time and outputs a universal asynchronous receiver and transmitter (UART) signal and a general-purpose input and output (GP I / O) signal to the host drive controller 3. The control circuit board 41 is embedded in the upper surface of the main unit 1 and electrically connected to the host drive controller 3. Furthermore, the control circuit board 41 is communicatively connected to an external element or device via at least one connection interface 412. In this embodiment, the control circuit board 41 is provided with a plurality of connection interfaces 412, and these plurality of connection interfaces 412 are communicatively connected to the gas detection main unit 42, the host drive controller 3, and the wired communication port 43, respectively, but are not limited to this. In a specific embodiment, the control circuit board 41 may be connected to the gas detection unit 42, the host drive controller 3, and the wired communication port 43 by selecting one connection interface 412. The control circuit board 41 includes a power converter 411, a microcontroller (MCU) 413, and a wireless communication device 414. The power converter 411 outputs the required DC voltage by DC voltage division modulation and provides this required DC voltage to the gas detection unit 42 and the host drive controller 3 via the connection interface 412 to operate them. The microcontroller (MCU) 413 receives a serial communication (IIC) signal as input formed from detection data output from the gas detection unit 42 via the connection interface 412, performs calculations and analysis of the detection data, and outputs general-purpose asynchronous transceiver (UART) signals and general-purpose input / output (GP I / O) signals for controlling the host drive controller 3, which is connected via the connection interface 412.The wireless communicator 414 receives the detection data and transmits the detection data to an external network-connected cloud computing service device 5 via wireless communication. The network-connected cloud computing service device 5 collects and analyzes the detection data and monitors it in real time, thereby intelligently selecting a control command. After the wireless communicator 414 receives it, it transmits the control command to the microcontroller (MCU) 413 and outputs a universal asynchronous receiver / transmitter (UART) signal and a general-purpose input / output (GPIO) signal for controlling the host drive controller 3. Thereby, the host drive controller 3 is controlled to control the startup of the air guide fan 21 and dynamically adjust the operation frequency and the output air volume.

[0011] Further, the network-connected smart fresh air purifier further includes the wired communication port 43. The wired communication port 43 is electrically connected to the control circuit board 41 via the connection interface 412 for communication with an external wired device. The received detection data is transmitted to an external network-connected cloud computing service device 5 via wired communication. The detection data is collected and analyzed and monitored in real time, thereby intelligently selecting a control command. After the control command is received by the wired communication port 43, it is transmitted to the microcontroller (MCU) 413 and outputs a universal asynchronous receiver / transmitter (UART) signal and a general-purpose input / output (GPIO) signal for controlling the host drive controller 3. The host drive controller 3 is controlled to control the startup of the air guide fan 21 and dynamically adjust the operation frequency and the output air volume. Here, the wired communication port 43 is an RS485 port that communicates with the network-connected cloud computing service device 5 via a wired connection.

[0012] Refer to FIGS. 4A, 4B, 5, 6A-6C, and 7. The gas detection body 42 includes a base 421, a piezoelectric actuator 422, a drive circuit board 423, a laser member 424, a particulate sensor 425, an outer cover 426, and a gas sensor 427.

[0013] The base 421 comprises a laser installation area 4211, a gas inlet groove 4212, a gas induction assembly mounting area 4213, and a gas exhaust groove 4214. The gas inlet groove 4212 is provided with an intake port 4215, and light-transmitting windows 4216 penetrate both side walls, communicating with the laser installation area 4211. The gas induction assembly mounting area 4213 communicates with the gas inlet groove 4212, and a ventilation hole 4217 is formed through its bottom surface. The gas exhaust groove 4214 communicates with the ventilation hole 4217 and is provided with an exhaust port 4218. The outer cover 426 covers the base 421 and has side plates 4261. The side plates 4261 have an intake frame port 4262 and an exhaust frame port 4263. The intake port 4262 corresponds to the intake port 4215 of the base 421, and the exhaust port 4263 corresponds to the exhaust port 4218 of the base 421.

[0014] The laser member 424, the particulate sensor 425, and the gas sensor 427 are all mounted on the drive circuit board 423 and electrically connected, and are located within the base 421 when the drive circuit board 423 is installed. The drive circuit board 423 has been omitted from this explanation in order to clearly illustrate the positional relationship between the laser member 424, the particulate sensor 425, and the base 421. The laser member 424 is housed within the laser installation area 4211 of the base 421, and the particulate sensor 425 is housed within the gas inlet groove 4212 of the base 421 and is aligned with the laser member 424. The laser member 424 also corresponds to the light transmission window 4216, and the light transmission window 4216 allows the laser light emitted from the laser member 424 to pass through, thereby irradiating the gas inlet groove 4212 with laser light. The beam path emitted from the laser member 424 passes through the light transmission window 4216 and is perpendicular to the gas inlet groove 4212. The beam emitted from the laser member 424 passes through the light transmission window 4216 and enters the gas inlet groove 4212, irradiating the gas in the gas inlet groove 4212. When the beam comes into contact with suspended particulate matter in the gas, it scatters and generates a projected light spot. Since the particulate sensor 425 is positioned perpendicular to this spot, it receives the scattered projected light spot and calculates the gas detection data. The light source emitted by the laser member 424 is a parallel light source and passes through the light transmission window 4216.

[0015] The gas sensor 427 is positioned and housed within the gas discharge channel 4214 and detects contamination of the gas introduced into the gas discharge channel 4214. In a preferred embodiment of the present invention, the particulate sensor 425 detects suspended particulate matter and outputs detection data, and the gas sensor 427 is a volatile organic compound sensor that detects carbon dioxide or total volatile organic compound gas and outputs detection data. Alternatively, the gas sensor 427 is a formaldehyde sensor that detects formaldehyde gas and outputs detection data. Alternatively, the gas sensor 427 is a bacterial sensor that detects bacteria or fungi and outputs detection data. Alternatively, the gas sensor 427 is a virus sensor that detects virus gas and outputs detection data. Alternatively, the gas sensor 427 is a temperature and humidity sensor that detects the temperature and humidity of the gas and outputs detection data.

[0016] As shown in Figures 6C and 7, the piezoelectric actuator 422 is housed in the gas induction assembly mounting area 4213 of the base 421. The gas induction assembly mounting area 4213 communicates with the gas inlet groove 4212. When the drive circuit board 423 is mounted inside the base 421 and the outer cover 426 covers the outside of the base 421, the intake port 4262 forms an intake path corresponding to the intake port 4215 of the base 421, and the exhaust port 4263 forms an exhaust path corresponding to the exhaust port 4218 of the base 421. In this case, when the piezoelectric actuator 422 is operated, it draws gas from the gas inlet groove 4212, allows it to enter the piezoelectric actuator 422, passes it through the vent hole 4217 of the gas induction assembly mounting area 4213, and discharges it into the gas discharge groove 4214. Finally, when the gas enters the gas discharge channel 4214, the piezoelectric actuator 422 continuously transports the gas from the intake path to the gas discharge channel 4214. As a result, the gas in the gas discharge channel 4214 is pushed out into the exhaust path and discharged to the outside via the exhaust port 4218 and the exhaust frame port 4263, achieving high-speed and high-volume transport of gas.

[0017] The structure of the gas detection unit 42 has been described above, but the detailed structure of the piezoelectric actuator 422 will be described below.

[0018] As shown in Figures 8A and 8B, the piezoelectric actuator 422 comprises a nozzle plate 4221, a chamber frame 4222, an actuator element 4223, an insulating frame 4224, and a conductive frame 4225. Here, the nozzle 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 vibrates in a curved manner, and its shape and size correspond to the inner edge of the gas induction assembly mounting area 4213. The hollow hole 4221b passes through the center of the suspension plate 4221a to allow gas to flow. In a preferred embodiment of the present invention, the shape of the suspension plate 4221a may be any one of a square, a circle, an ellipse, a triangle, or a polygon.

[0019] The chamber frame 4222 is stacked on top of the vent plate 4221, and its appearance corresponds to that of the vent plate 4221. The actuator element 4223 is stacked on top of the chamber frame 4222, defining a resonant chamber 4226 between the chamber frame 4222 and the suspension plate 4221a. The insulating frame 4224 is stacked on top of the actuator element 4223, and its appearance approximates that of the chamber frame 4222. The conductive frame 4225 is stacked on top of the insulating frame 4224, and its appearance approximates that of the insulating frame 4224. The conductive frame 4225 has conductive pins 4225a and conductive electrodes 4225b, the conductive pins 4225a extending outward from the outer edge of the conductive frame 4225, and the conductive electrodes 4225b extending inward from the inner edge of the conductive frame 4225.

[0020] Furthermore, the actuator element 4223 comprises a piezoelectric carrier plate 4223a, a resonance adjustment plate 4223b, and a piezoelectric plate 4223c. Here, the piezoelectric carrier plate 4223a is stacked on the chamber frame 4222. The resonance adjustment plate 4223b is stacked on the piezoelectric carrier plate 4223a. The piezoelectric plate 4223c is stacked on the resonance adjustment plate 4223b. The resonance adjustment plate 4223b and the piezoelectric plate 4223c are housed in an insulating frame 4224. The conductive electrode 4225b of the conductive frame 4225 and the piezoelectric plate 4223c are electrically connected. Here, in a preferred embodiment of the present invention, both the piezoelectric carrier plate 4223a and the resonance adjustment plate 4223b are made of conductive material. The piezoelectric carrier plate 4223a has piezoelectric pins 4223d, and the piezoelectric pins 4223d and conductive pins 4225a are connected to a drive circuit (not shown) on the drive circuit board 423 to receive a drive signal (which may be a drive frequency and drive voltage). The piezoelectric pins 4223d, piezoelectric carrier plate 4223a, resonance adjustment plate 4223b, piezoelectric plate 4223c, conductive electrode 4225b, conductive frame 4225, and conductive pins 4225a form a transmission path for the drive signal. The conductive frame 4225 and actuator element 4223 are insulated by an insulating frame 4224 to prevent short circuits and ensure that the drive signal is transmitted to the piezoelectric plate 4223c. When the piezoelectric plate 4223c receives a drive signal, it deforms due to the piezoelectric effect, further driving the piezoelectric carrier plate 4223a and resonance adjustment plate 4223b to generate reciprocating bending vibrations.

[0021] To further explain, the resonance adjustment plate 4223b is located between the piezoelectric plate 4223c and the piezoelectric carrier plate 4223a, and functions as a buffer between them, thereby adjusting the vibration frequency of the piezoelectric carrier plate 4223a. Basically, the thickness of the resonance adjustment plate 4223b is greater than that of the piezoelectric carrier plate 4223a, and the vibration frequency of the actuator element 4223 is adjusted by changing the thickness of the resonance adjustment plate 4223b. The blowhole plate 4221, chamber frame 4222, actuator element 4223, insulating frame 4224, and conductive frame 4225 are stacked in this order and positioned within the gas induction assembly mounting area 4213, thereby positioning the piezoelectric actuator 422 within the gas induction assembly mounting area 4213. The piezoelectric actuator 422 has a gap 4221c defined between the suspension plate 4221a and the inner edge of the gas induction assembly mounting area 4213 for gas to flow through.

[0022] A fluid chamber 4227 is defined between the nozzle plate 4221 and the bottom surface of the gas induction assembly mounting area 4213. The fluid chamber 4227 communicates with a resonant chamber 4226 between the actuator element 4223, the chamber frame 4222, and the suspension plate 4221a via the hollow hole 4221b of the nozzle plate 4221. By bringing the vibration frequency of the gas in the resonant chamber 4226 closer to the vibration frequency of the suspension plate 4221a, a Helmholtz resonance effect is generated between the resonant chamber 4226 and the suspension plate 4221a, improving the gas transport efficiency. As the piezoelectric plate 4223c moves away from the bottom surface of the gas induction assembly mounting area 4213, the suspension plate 4221a of the nozzle plate 4221 is moved away from the bottom surface of the gas induction assembly mounting area 4213 by the piezoelectric plate 4223c, causing the volume of the fluid chamber 4227 to rapidly expand, the internal pressure to decrease and become negative, the gas outside the piezoelectric actuator 422 is drawn in and flows in through the gap 4221c, enters the resonant chamber 4226 through the hollow hole 4221b, the air pressure inside the resonant chamber 4226 increases and a pressure gradient is generated. When the suspension plate 4221a of the nozzle plate 4221 is moved toward the bottom surface of the gas induction assembly mounting area 4213 by the piezoelectric plate 4223c, the gas in the resonant chamber 4226 rapidly flows out through the hollow hole 4221b, pushing out the gas in the fluid chamber 4227. The combined gas is then rapidly and in large quantities ejected through the vent hole 4217 of the gas induction assembly mounting area 4213 in a state close to the ideal gas according to Bernoulli's theorem.

[0023] By repeating the operations shown in Figures 9B and 9C, the piezoelectric plate 4223c vibrates back and forth, and due to the principle of inertia, the air pressure inside the resonant chamber 4226 after exhaust becomes lower than the equilibrium pressure, causing the gas to re-enter the resonant chamber 4226. In this way, by controlling the vibration frequency of the gas inside the resonant chamber 4226 to approach the vibration frequency of the piezoelectric plate 4223c, Helmholtz resonance is generated, enabling high-speed and high-volume transport of gas.

[0024] As shown in Figures 10A to 10C, the gas enters entirely through the intake frame port 4262 of the outer cover 426, passes through the intake port 4215, enters the gas inlet groove 4212 of the base 421, and flows to the position of the particulate sensor 425. The piezoelectric actuator 422 is continuously driven to draw in the gas in the intake path, which is advantageous for the rapid introduction and stable flow of the external gas, and the gas passes above the particulate sensor 425. At this time, the beam from the laser member 424 passes through the light transmission window 4216 and enters the gas inlet groove 4212, and also passes above the particulate sensor 425. When the beam from the laser member 424 is irradiated onto the suspended particulate matter in the gas, scattering phenomena and projection points are generated, and the particulate sensor 425 receives the projection points generated by scattering and performs calculations to obtain information on the particle size and number of suspended particulate matter contained in the gas. The gas above the particulate sensor 425 is also driven by the piezoelectric actuator 422 and introduced into the vent 4217 of the gas induction assembly mounting area 4213, and enters the gas discharge groove 4214. Finally, after the gas enters the gas discharge groove 4214, the piezoelectric actuator 422 continues to send gas into the gas discharge groove 4214, so that the gas inside the gas discharge groove 4214 is pushed out and discharged to the outside through the exhaust port 4218 and the exhaust frame port 4263.

[0025] Understanding the overall structure of the network-connected smart fresh air purifier of the present invention, the gas detection module 4 built into the network-connected smart fresh air purifier of the present invention is equipped with a cloud connectivity function. By applying this to the indoor air purification network control system, all air pollution detection data can be uploaded to the network-connected cloud computing service device 5, allowing the user to remotely check the air quality of indoor space A. In particular, the purification efficiency can be monitored and automatically adjusted in real time, enabling energy saving, improving air comfort, and maintaining optimal air quality in the indoor environment. As shown in Figure 11, the network-connected cloud computing service device 5 comprises 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 smart control platform 55. Here, the wireless network cloud computing service module 51 receives data detected by the gas detection module 4 of the network-connected smart fresh air purifier and transmits control commands. The wireless network cloud computing service module 51 receives detection data, transmits and stores it in the cloud control service unit 52 to form an air pollution big data database, performs intelligent calculations and comparisons using the air pollution big data database, outputs control commands and transmits them back to the wireless network cloud computing service module 51, and transmits them via the wireless network cloud computing service module 51 to the gas detection module 4 of the network-connected smart fresh air purifier to control their activation.The device management unit 53 receives communication information from the gas detection module 4 of the network-connected smart fresh air purifier via the wireless network cloud computing service module 51 to manage user registration and device binding. It also provides management information to the application unit 54, such as maintenance management of the network-connected smart fresh air purifier, automatic inspection, analysis, processing and improvement of abnormal areas, control and inspection measurement of whether cleanliness requirements are met, feedback of customer requirements, and correction mechanisms for improving software and hardware technology, thereby controlling and managing the system. The application unit 54 also acquires and displays air quality detection data via the cloud control service unit 52, allowing users to understand the air pollution removal status in real time using their mobile phones or communication devices. Furthermore, users can control the operation of the indoor air purification network control system through the application unit 54 on their mobile phones or communication devices. Furthermore, the AI ​​smart control platform 55 intelligently selects control commands by collecting and analyzing the obtained air quality detection data and monitoring it in real time, and transmits them to the gas detection module 4 of the network-connected smart fresh air purifier. This controls the host drive controller 3, which in turn controls the operation of the air guide fan 21 and dynamically adjusts the operating frequency and output airflow. In other words, the intelligently determined control commands are transmitted to the host drive controller 3, which controls the operation of the air guide fan 21 and dynamically adjusts the operating frequency and output airflow of the air guide fan 21. Specifically, the greater the gas detection data is compared to the safety detection value, the greater the output airflow of the air guide fan 21 is adjusted, and the enhanced purification mode of the air guide fan 21 is automatically activated. The closer the gas detection data is to the safety detection value, the smaller the output airflow of the air guide fan 21 is adjusted. By collecting and analyzing the detection data and monitoring it in real time, the operating frequency of the air guide fan 21 is dynamically adjusted, the system automatically switches to a low power consumption mode, reduces airflow noise, and ultimately stops operation when the air quality in indoor space A becomes zero, reducing unnecessary energy consumption.

[0026] Refer to Figure 2. The filter unit 22 of the present invention can be a combination of various embodiments. In some embodiments, the filter unit 22 may be a filter 22a, which may be a MERV (Minimum Efficiency Reporting Value) class 8 or higher, or a high-performance air filter (HEPA), which aims to filter and purify introduced air pollution by adsorbing chemical fumes, bacteria, dust particles and pollen contained in the air pollution. In particular, the high-performance air filter (HEPA) in this invention is a high-performance air filter (HEPA) class 10 or higher, with a dust holding capacity exceeding 12,000 mg. Alternatively, filter 22a may be a more efficient ULPA14 filter class, further improving filtration efficiency and satisfying higher cleanliness requirements. In some embodiments, the filter unit 22 can be further combined with physical or chemical materials to provide a sterilizing effect on the air pollution passing through it. The airflow direction from the induction fan 21 is indicated by the arrow. By applying a decomposition layer to the filter unit 22, air pollution can be sterilized and removed by chemical means. The decomposition layer may be activated carbon 22b, which can remove organic and inorganic substances in the air pollution, as well as colored and odorous substances. In particular, in this invention, the formaldehyde absorption capacity of the activated carbon 22b exceeds 1500 mg. In some embodiments, the filter unit 22 may be combined with a light irradiation element that sterilizes and removes air pollution by chemical means. The light irradiation element is a photocatalytic unit including a photocatalyst 22c and an ultraviolet lamp 22d. This further improves the efficiency of removing pollutants and allergens from the air. When the photocatalyst 22c is irradiated by the ultraviolet lamp 22d, it converts light energy into electrical energy, decomposing harmful substances in the air pollution to disinfect and sterilize, achieving a filtration and sterilization effect. In particular, in this invention, the output of the ultraviolet lamp 22d is 120 mW or more.The light irradiation element may be a photoplasma unit of the nanophototube 22e. When introduced air pollutants are irradiated by the nanophototube 22e, oxygen molecules and water molecules in the air pollutants are decomposed into a highly oxidizing photoplasma, forming an ion flow that destroys organic molecules. This decomposes gas molecules such as volatile formaldehyde, toluene, and volatile organic compounds (VOCs) contained in the air pollutants into water and carbon dioxide, further improving the efficiency of removing airborne pollutants and allergens and achieving a filtration and sterilization effect. In some embodiments, the filter unit 22 may be combined with a decomposition unit that sterilizes and removes air pollutants by chemical means. The decomposition unit may be a negative ion unit 22f. By giving positive charges to fine particles contained in the introduced air pollutants and causing them to adhere to negative charges, the efficiency of removing airborne pollutants and allergens is further improved, achieving a filtration and sterilization effect on the introduced air pollutants. The decomposition unit may be a plasma ion unit 22g. Plasma ions ionize oxygen molecules and water molecules contained in the air pollutants to form positive ions (H. + ) and anions (O 2- The decomposition unit generates ions, and after the substance with water molecules attached around the ions attaches to the surface of viruses and bacteria, a chemical reaction converts it into highly oxidative reactive oxygen species (hydroxyl radicals, OH groups), which remove hydrogen from the proteins on the surface of viruses and bacteria, and oxidatively decompose them, thereby decomposing and removing airborne pollutants, allergens, and microorganisms, improving air purity and providing a filtration and sterilization effect on introduced air pollutants. The decomposition unit may also be an electrostatic filtration unit 22h, which uses electrostatic force to capture and remove airborne particulate matter (e.g., dust, pollen, bacteria, and other pollutants).

This network-connected smart fresh air purifier has a built-in gas detection module 4 with cloud connectivity, which enables real-time monitoring and adjustment. Furthermore, by coordinating with a network-connected cloud computing service device 5 of the indoor air purification network control system, it achieves the following effects. Real-time monitoring and adjustment effect: The built-in gas detection module 4 can monitor indoor air humidity, temperature, and air pollution detection data in real time. The detection data is transmitted to the network-connected cloud computing service device 5 via the Internet of Things (wireless or wired communication). The AI ​​smart control platform 55 controls the operation of the air guide fan 21 and dynamically adjusts the operating frequency and output airflow based on the detection data monitored, collected, and analyzed in real time, thereby improving purification efficiency. Specifically, the greater the gas detection data is than the safety detection value, the greater the output airflow of the air guide fan 21 is adjusted, and the closer the gas detection data is to the safety detection value, the smaller the output airflow of the air guide fan 21 is adjusted. Intelligent Filtration Effect: If the carbon dioxide (CO2) air quality detection data in indoor space A is too high, the system automatically increases the amount of fresh air introduced, bringing gas from outdoor space B into indoor space A to improve indoor air circulation and air quality. Intelligent Cloud Connectivity Effect: The gas detection module 4 has cloud connectivity and can upload all air pollution detection data to the network-connected cloud computing service device 5, allowing the user to remotely check the air quality of indoor space A. Multiple Filtration Effect: The filter unit 22 of the filter module 2 can be combined with activated carbon, high-performance filters, electrostatic filtration, photocatalytic units, negative ion units, plasma units, etc., to achieve optimal filtration effects according to various pollution sources.Multiple Device Collaborative Operation Effect: When multiple network-connected smart fresh air purifiers are placed in the same indoor space A, the network-connected cloud computing service device 5 can form a collaborative purification network by adjusting its operation based on the air pollution detection data of each device, thereby achieving optimal air quality throughout the entire area. In other words, the network-connected cloud computing service device 5 can detect different detection data from the gas detection modules 4 of network-connected smart fresh air purifiers located in different places. Furthermore, the network-connected cloud computing service device 5 can send control signals to the corresponding network-connected smart fresh air purifiers based on different air quality conditions. The network-connected cloud computing service device 5 controls the activation of the air guide fan 21 and adjusts the operating frequency of the air guide fan 21. Energy-saving effect: When the humidity of the indoor and outdoor environments is similar, or when the air quality meets the standard, the network-connected cloud computing service device 5 dynamically adjusts the operating frequency of the air guide fan 21 based on detection data monitored, collected, and analyzed in real time, automatically switches to low power consumption mode, reduces airflow noise, and ultimately stops operation when the air quality in indoor space A is completely purified, thereby reducing unnecessary energy consumption.

[0028] Based on the above, the present invention provides a network-connected smart fresh air purifier that incorporates a filter module 2 and a gas detection module 4 to detect air pollution in real time. Furthermore, the gas detection module 4 is equipped with a cloud connectivity function, making remote monitoring and operation by the user easy. In addition, air pollution detection data is transmitted to a network-connected cloud computing service device 5 via the Internet of Things (wireless or wired communication), and the network-connected cloud computing service device 5 collects and analyzes the air pollution detection data and monitors it in real time, intelligently selecting control commands and transmitting them to the gas detection module 4 to control the activation of the air guide fan 21 and dynamically adjust the operating frequency and output airflow of the air guide fan 21, thereby improving the purification efficiency. Furthermore, air from the outdoor space enters through the ventilation channel, is guided by the air guide fan 21, filtered while passing through the filter unit 22, and then enters the indoor space, thereby achieving ventilation and maintaining the balance of carbon dioxide (CO2) air quality detection data between the indoor and outdoor spaces. The network-connected smart fresh air purifier of the present invention, by linking with an indoor air purification network control system, can constitute a complete real-time processing system and has extremely high industrial value.
