The first housing 1 is provided with a first air inlet 11, a second air inlet 12, and a first air outlet 13. The first air inlet 11 is used to introduce outdoor fresh air, the second air inlet 12 is used to introduce indoor return air, and the first air outlet 13 is used to output purified air. The first purification component 2 is disposed inside the first housing 1, and the first purification component 2 includes a first purification... Module 21 and the first energy storage module 22 are electrically connected. The input end of the first purification module 21 faces the first air inlet 11. The second purification component 3 is disposed inside the first housing 1 and is located at the output end of the first purification component 2. The second air inlet 12 is located between the first purification component 2 and the second purification component 3. The second purification component 3 includes a second purification module 31 and a second energy storage module 32, which are electrically connected. The fan 4 is disposed inside the first housing 1, with its input end facing the second purification module 3. The output end of fan 4 is positioned facing the first air outlet 13; the coil assembly 5 is positioned between fan 4 and the first air outlet 13, and is used to regulate the humidity and temperature of the purified air; the pipeline assembly 7 is connected to the first air outlet 13, and includes a first pipeline 71 and a second pipeline 72, the first pipeline 71 being connected to the auxiliary room and the second pipeline 72 being connected to the operating room; the first active composite particle generator 6 is positioned between the coil assembly 5 and the first air outlet 13, and is used to add active composite particles to the purified air. The purified air enters the first duct 71 and the second duct 72, as well as the operating room and auxiliary rooms, to sterilize and disinfect the air. The air diffuser assembly 8 includes a second housing 81, a first branch 82, and a second branch 83. The first branch 82 and the second branch 83 are respectively connected to the second duct 72. One side of the second housing 81 is connected to the first branch 82, and the other side of the second housing 81 is connected to the second branch 83. The second duct 72 is connected to the operating room through the air diffuser assembly 8. The control unit 9 is electrically connected to the first purification assembly 2, the second purification assembly 3, the fan 4, the coil assembly 5, and the first active composite particle generator 6.

[0080] In this embodiment, the first housing 1 is the main outer shell of the air purification and disinfection system for the operating room, used to house and integrate various functional modules, and can be a metal or plastic casing. The first purification component 2, the second purification component 3, the fan 4, the coil assembly 5, and the first active composite particle generator 6 are placed inside the first housing 1. The first purification module 21, the second purification module 31, and the third purification module 841 and fourth purification module 851 (described later) can be air purification devices employing technologies such as high-efficiency filters, ultraviolet germicidal lamps, and activated carbon adsorption. The control unit 9 is an electronic control device capable of centralized monitoring and automated control of the entire system's operation, and can be a controller based on a microcontroller or industrial computer.

[0081] The first active composite particle generating device 6 in this embodiment, and the second active composite particle generating device 843 and the third active composite particle generating device 853 described below, are all active composite particle generators. Specifically, the active composite particle generator includes a discharge electrode and a high-voltage electrode plate. The discharge electrode and the high-voltage electrode plate can be circular, needle-shaped, or peach-shaped. For specific structures, please refer to the "An Active Composite Particle Generating Device" published in CN218388045U. In this device, the PN junction below the discharge electrode condenses water molecules in the air onto the surface of the discharge electrode through a thermoelectric effect, forming aggregated water droplets. After generating high voltage, the high-voltage electrode plate pulls the water droplets on the surface of the discharge electrode upward to the tip to form a Taylor cone and cause corona discharge, ionizing and generating active composite particles. Using a needle-shaped electrode results in less water at the tip, making it easier to generate a large amount of ozone; using a circular electrode makes it difficult to form a Taylor cone; and a peach-shaped electrode, because it satisfies the Taylor curve, makes it easier to form a Taylor cone of discharge and generates less ozone.

[0082] The active composite particle generator produces reactive oxides, such as oxygen ions, superoxide anions, and hydroxyl radicals. These reactive oxides have strong oxidizing and bactericidal effects, capable of destroying the cell walls and membranes of microorganisms such as bacteria, viruses, and molds, thereby killing them. The reactive oxides and negative ions produced by the active composite particle generator can also react chemically with harmful gases, decomposing them into harmless substances or converting them into easily treatable forms. For example, the active composite particle generator can decompose volatile organic compounds such as formaldehyde, benzene, and toluene into carbon dioxide and water, thereby reducing the concentration of harmful gases in the air.

[0083] Fan 4 is a fan device that provides airflow drive for the entire system. It can be a centrifugal fan or an axial fan. Outdoor fresh air is driven by fan 4 and enters the first housing 1 through the first air inlet 11. After passing through the first purification module 21, the particulate matter in the outdoor fresh air is initially intercepted and filtered. The air after interception is then subjected to secondary interception and filtration by the second purification module 31. The filtered air then passes through the coil assembly 5 for dehumidification, heating, and cooling regulation. The coil assembly 5 can be a refrigeration and heating device using condensation heating technology. The air then passes through the first active composite particle generator 6, which generates highly efficient sterilization and disinfection active composite particles that are carried into the pipeline assembly 7. That is, the first active composite particle generator 6 can kill bacteria and viruses that are about to enter the pipeline assembly 7. The piping assembly 7 can be made of metal pipes or flexible tubing, including a first pipe 71 and a second pipe 72. The air in the second pipe 72 is divided into two channels, which are connected to a first branch 82 and a second branch 83 respectively. The first branch 82 and the second branch 83 can be circular pipes. The air passing through the first branch 82 and the second branch 83 flows into the operating room through the air distribution assembly 8. The air in the operating room passes through the return air duct in the operating room and enters the first housing 1 from the second air inlet 12, so that it can be recirculated into the operating room.

[0084] The first purification module 21 is equipped with a first energy storage module 22, which provides energy support for the first purification module 21. This energy storage module can be an integrated battery or a supercapacitor, among other energy storage devices. In the event of an emergency power outage, the first purification module 21 may fail due to power failure, and the particles adsorbed on it may detach. The first energy storage module 22 can maintain power supply to the first purification module 21 for a short period during a power outage, preventing the particles adsorbed on it from becoming unusable due to power failure. Similarly, the second purification module 31 is also equipped with a second energy storage module 32 to prevent the particles adsorbed on the second purification module 31 from detaching due to power failure.

[0085] This embodiment employs a dual purification system consisting of a first purification module 21 and a second purification module 31, along with a first active composite particle generator 6. This system efficiently removes particulate matter, bacteria, and viruses from the air, significantly improving air cleanliness. Secondly, the active composite particles possess strong oxidizing and bactericidal properties. Following the purified air into the first and second pipelines, as well as the operating room and auxiliary rooms, they effectively kill bacteria, viruses, and other microorganisms, achieving excellent disinfection results. Furthermore, the system is equipped with a precise temperature and humidity control device, ensuring that the operating room environment meets temperature and humidity standards through the coil assembly 5. The system is equipped with backup power supplies for the first purification module 21 and the second purification module 31, namely a first energy storage module 22 and a second energy storage module 32. In the event of a sudden power outage, these backup power supplies can maintain the operation of critical equipment for a short period, preventing the release of contaminants due to power failure, ensuring a continuously clean surgical environment, and ensuring that the system is always in optimal operating condition. The system possesses high-efficiency purification, powerful disinfection, precise temperature and humidity control, and reliable emergency power outage response capabilities.

[0086] In some embodiments, the air purification and disinfection system for operating rooms further includes: a third purification component 84 and a fourth purification component 85.

[0087] In this embodiment, the third purification module 841 is equipped with a third energy storage module 842, and the fourth purification module 851 is equipped with a fourth energy storage module 852. When powered on, the third energy storage module 842 and the fourth energy storage module 852 are charged. In the event of a power outage, the third energy storage module 842 and the fourth energy storage module 852 supply power to the third purification module 841 and the fourth purification module 851 respectively, which can prevent the purification modules from failing due to a sudden power outage, causing the adsorbed particulate matter to fall off.

[0088] This embodiment is equipped with a third purification component 84 and a fourth purification component 85 to further purify the air, and is also equipped with corresponding energy storage modules (i.e., the third energy storage module 842 and the fourth energy storage module 852). In the event of a sudden power outage, it can maintain the operation of critical equipment for a short period of time, avoid the release of pollutants caused by the power outage, ensure the continuous cleanliness of the surgical environment, ensure that the system is always in the best operating state, and further improve the reliability and stability of the system.

[0089] In some embodiments, the third purification component 84 further includes a second active composite particle generator 843, which is disposed at the output end of the third purification module 841. The second active composite particle generator 843 is used to add active composite particles to the purified air, which then enter the second housing 81 and the operating room with the purified air to sterilize and disinfect the air. The fourth purification component 85 further includes a third active composite particle generator 853, which is disposed at the output end of the fourth purification module 851. The third active composite particle generator 853 is used to add active composite particles to the purified air, which then enter the second housing 81 and the operating room with the purified air to sterilize and disinfect the air. The control unit 9 is electrically connected to the second active composite particle generator 843 and the third active composite particle generator 853.

[0090] In this embodiment, the air inlet of the ventilation device is equipped with a second active composite particle generator 843 and a third active composite particle generator 853. The air passing through the third purification module 841 and the fourth purification module 851 drives the active composite particles with disinfection and sterilization functions generated by the second active composite particle generator 843 and the third active composite particle generator 853 to release disinfection factors and enhance the continuous disinfection effect of viruses and microorganisms in the operating room.

[0091] This embodiment, by installing a second active composite particle generator 843 and a third active composite particle generator 853 at the air inlet of the ventilation device, can continuously release active composite particles with disinfection and sterilization functions into the operating room, further enhancing the disinfection effect against viruses and microorganisms. The control unit 9 is electrically connected to the second and third active composite particle generators 843 and 853 to achieve precise temperature and humidity control and intelligent monitoring, ensuring that the temperature and humidity of the operating room environment meet the standards, and monitoring the entire system's operating status in real time and automatically adjusting it to ensure the system operates at its optimal state.

[0092] In some embodiments, the third purification component 84 further includes a first electric air valve 844, which is disposed at the input end of the third purification module 841. The first electric air valve 844 is used to blow purified air into the third purification module 841. The fourth purification component 85 further includes a second electric air valve 854, which is disposed at the input end of the fourth purification module 851. The second electric air valve 854 is used to blow purified air into the fourth purification module 851. The control unit 9 is electrically connected to the first electric air valve 844 and the second electric air valve 854 respectively. The air dispersing component 8 further includes a damping scattering mesh 86, which is disposed at the connection between the second housing 81 and the operating room.

[0093] In this embodiment, if the third purification module 841 and the fourth purification module 851 malfunction, intelligent opening and closing adjustment can be realized. When the control unit 9 detects the failure of the third purification module 841 or the fourth purification module 851 through changes in current and voltage, it immediately closes the first electric air valve 844 or the second electric air valve 854 at the front end to prevent the dust on the third purification module 841 or the fourth purification module 851 from being blown out. The air distribution device is provided with several air outlets (more than 2). When one of them fails and closes, the other air outlets work normally, realizing a multi-filtration protection system.

[0094] In this embodiment, a first electric air valve 844 and a second electric air valve 854 are respectively provided at the input ends of the third purification component 84 and the fourth purification component 85. These valves can intelligently regulate the opening and closing of the third purification component 84 and the fourth purification component 85. If any purification module malfunctions, the corresponding electric air valve will immediately close to prevent dust from being blown out of the faulty module. Simultaneously, the air distribution device has multiple air outlets; even if one outlet malfunctions and closes, the others can still operate normally, providing multiple layers of protection. Furthermore, a damping and scattering mesh 86 is provided at the air outlet of the air distribution device to smoothly and evenly distribute the airflow, ensuring good air circulation in the operating room.

[0095] In some embodiments, the first purification component 2 further includes a first particle sensor 23 disposed at the output end of the first purification module 21, the first particle sensor 23 being used to detect the concentration of impurity particles in the air output by the first purification module 21; the second purification component 3 further includes a second particle sensor 33 disposed at the output end of the second purification module 31, the second particle sensor 33 being used to detect the concentration of impurity particles in the air output by the second purification module 31; the third purification component 84 further includes a third particle sensor 845 disposed at the output end of the third purification module 841, the third particle sensor 845 being used to detect the concentration of impurity particles in the air output by the third purification module 841; the fourth purification component 85 further includes a fourth particle sensor 855 disposed at the output end of the fourth purification module 851, the fourth particle sensor 855 being used to detect the concentration of impurity particles in the air output by the fourth purification module 851.

[0096] In this embodiment, the air distribution assembly 8 includes a first electric air valve 844, a second electric air valve 854, a third purification module 841, a fourth purification module 851, a third energy storage module 842, a fourth energy storage module 852, a second active composite particle generator 843, a third active composite particle generator 853, a second housing 81, and a damping scattering net 86.

[0097] The first purification module 21 is equipped with a first particle sensor 23 at its rear end. The first particle sensor 23 can detect the concentration of particulate matter in the air passing through the first purification module 21. The filtration efficiency of the first purification module 21 can be determined based on the particulate matter concentration collected by the first particle sensor 23. The control unit 9 controls and reminds the user if the filtration efficiency is lower than the critical value. If so, the user will be reminded to clean or replace the module.

[0098] The second purification module 31 is equipped with a second particle sensor 33 at its rear end. The second particle sensor 33 can detect the concentration of particulate matter in the air passing through the second purification module 31. The filtration efficiency of the second purification module 31 can be determined based on the particulate matter concentration collected by the second particle sensor 33. The control unit 9 can then control and provide reminders. If the filtration efficiency is lower than a critical value, it will remind the user to clean or replace the module.

[0099] The first purification module 21 is the primary filter for outdoor fresh air. Since outdoor fresh air has relatively poor air quality, the first purification module 21 will have a shorter lifespan for cleaning or replacement. The second purification module 31 filters indoor return air, which has relatively better air quality, and therefore has a longer lifespan for cleaning. The control unit 9 intelligently adjusts the on / off state of the first and second purification modules 21 and 31 based on the air particulate matter concentration fed back by the first and second particle sensors 23. This ensures that the first and second purification modules 21 and 31 maintain similar or near-identical cleaning and lifespan times, reducing labor costs for after-sales cleaning and maintenance.

[0100] The airflow from the first active composite particle generator 6 is split into two streams. One stream flows through the first branch 82, passing through the first electric air valve 844, the third purification module 841, the second active composite particle generator 843, and the third particle sensor 845, before entering the second chamber 81. The other stream flows through the second branch 83, passing through the second electric air valve 854, the fourth purification module 851, the third active composite particle generator 853, and the fourth particle sensor 855, before entering the second chamber 81. After mixing, the airflow is evenly scattered by the damped scattering net 86 before flowing into the operating room.

[0101] The first electric air valve 844 and the second electric air valve 854 are open by default. When the third particle sensor 845 or the fourth particle sensor 855 detects an abnormal particulate matter index, it indicates that the third purification module 841 and the fourth purification module 851 have failed. The corresponding first electric air valve 844 or second electric air valve 854, controlled by the control unit 9, will automatically close to prevent the concentration of particulate matter in the operating room from exceeding the standard due to the failure of the purification module.

[0102] In this embodiment, corresponding first particle sensors 23, 33, 845, and 855 are provided at the output terminals of the first purification module 21, the second purification module 31, the third purification module 841, and the fourth purification module 851, respectively, enabling real-time monitoring of the concentration of impurity particles in the purified air. Based on this monitoring data, the control unit 9 can intelligently adjust the activation time of each purification module to ensure that their service life remains approximately the same, thereby reducing subsequent maintenance costs.

[0103] In some embodiments, the first purification module 21, the second purification module 31, the third purification module 841, and the fourth purification module 851 are configured as electrostatic dust removal filter elements.

[0104] In this embodiment, the first purification module 21, the second purification module 31, the third purification module 841, and the fourth purification module 851 employ electrostatic adsorption. All four modules utilize electrostatic dust removal filter technology, significantly improving air purification efficiency and enhancing ease of use and cost-effectiveness. Specifically, the electrostatic dust removal filter utilizes electrostatic force to effectively capture fine particulate matter in the air, resulting in higher filtration efficiency. Compared to traditional mechanical filtration methods, electrostatic filters do not require frequent replacement; only periodic cleaning is needed for long-term use, greatly reducing consumable costs. Furthermore, the electrostatic dust removal filter itself has very low pressure loss and does not require additional fan power, further improving overall energy efficiency.

[0105] This embodiment uses an electrostatic dust removal filter element, which has a high purification and disinfection capacity. It can not only efficiently capture fine particulate matter in the air by utilizing the effect of electrostatic field force, but is also easy to clean and can be used for a long time, which greatly reduces the cost of consumables. While ensuring the stability and reliability of the system, it significantly reduces energy consumption and maintenance costs, and further improves the overall energy efficiency.

[0106] In some embodiments, the coil assembly 5 includes a first coil 51 and a second coil 52. The first coil 51 is disposed at the output end of the fan 4 and is configured to introduce liquid at a first preset temperature to cool and dehumidify the air output by the fan 4. The second coil 52 is disposed between the first coil 51 and the first active composite particle generator 6 and is configured to introduce liquid at a second preset temperature to heat the cooled and dehumidified air. The first preset temperature is lower than the second preset temperature.

[0107] In this embodiment, the first coil 51 is located at the outlet of the fan 4, through which a cooler refrigerant liquid is introduced. This effectively reduces the air temperature while removing moisture from the air, achieving a dehumidification effect. This not only reduces the bacterial and viral load in the air but also prevents condensation and other adverse conditions in the operating room. The second coil 52 is located between the first coil 51 and the first active composite particle generator 6, through which a warmer heat transfer medium is introduced. This reheats the cooled and dehumidified air, ensuring that the air temperature at the outlet meets the comfort requirements of the operating room while avoiding discomfort caused by excessive cooling. Furthermore, the temperature gradient configuration of the first coil 51 and the second coil 52 also helps to further improve the humidity uniformity of the air.

[0108] In this embodiment, a first coil 51 is installed at the outlet of the fan 4, through which a cooler refrigerant liquid is introduced. This can effectively reduce the air temperature while removing moisture from the air, thus achieving a dehumidification effect and reducing the load of bacteria and viruses in the air. A second coil 52 is introduced through which a hotter refrigerant liquid is introduced to reheat the cooled and dehumidified air, thereby ensuring that the air temperature at the outlet meets the comfort requirements of the operating room.

[0109] In some embodiments, the coil assembly 5 further includes an air conditioning unit 53, a water tank 54, a first inlet pipe 55, and a first return pipe 56. The water tank 54 is connected to the air conditioning unit 53. The first inlet pipe 55 is disposed between the water tank 54 and the first housing 1, and is connected to the outlet of the water tank 54. The first inlet pipe 55 is positioned towards the first coil 51. The first return pipe 56 is disposed between the water tank 54 and the first housing 1, and is connected to the inlet of the water tank 54. The first return pipe 56 is positioned towards the second coil 52.

[0110] In this embodiment, precise temperature and humidity control of the purified air is achieved by adding an air conditioning unit 53, a water tank 54, a first inlet pipe 55, and a first return pipe 56. Specifically, the water tank 54 is connected to the air conditioning unit 53, providing a temperature regulating medium for the entire temperature and humidity control loop. The first inlet pipe 55 connects the water outlet of the water tank 54 to the first coil 51, providing low-temperature cooling water to the first coil 51 to lower the air temperature and remove moisture from the air. The first return pipe 56 connects the return water discharged from the second coil 52 to the water inlet of the water tank 54, thus forming a closed-loop circulation. This not only precisely regulates the temperature and humidity parameters of the exhaust air to meet the environmental requirements of the operating room, but also significantly improves the energy efficiency of the system and reduces unnecessary energy loss.

[0111] This embodiment adds an air conditioning unit 53, a water tank 54, a first water inlet pipe 55, and a first water return pipe 56, forming a complete temperature and humidity control loop. This not only accurately adjusts the temperature and humidity parameters of the air outlet to meet the environmental requirements of the operating room, but also significantly improves the system's energy efficiency and reduces unnecessary energy loss.

[0112] In some embodiments, the coil assembly 5 further includes: a first temperature and humidity sensor 57 and a second temperature and humidity sensor 58. The first temperature and humidity sensor 57 is disposed between the second purification module 31 and the fan 4; the second temperature and humidity sensor 58 is disposed between the first active composite particle generator 6 and the first air outlet 13.

[0113] In this embodiment, the air passing through the first purification module 21 and the second purification module 31 is intelligently adjusted by the control unit 9 via the first temperature and humidity sensor 57 and the second temperature and humidity sensor 58. The filtered air is cooled, dehumidified, and heated by the first coil 51 and the second coil 52. The first coil 51 is connected to the first water inlet pipe 55 to cool and dehumidify the flowing air, and the second coil 52 is connected to the first water return pipe 56 to heat the flowing air.

[0114] This embodiment adds a first temperature and humidity sensor 57 and a second temperature and humidity sensor 58, forming an intelligent closed-loop temperature and humidity control system capable of detecting the temperature and humidity parameters of the air after the initial purification process and the final outlet air temperature and humidity. Based on the real-time feedback data from these two sensors, the control unit 9 can precisely adjust the coil assembly 5. This not only ensures stable and controllable air parameters at the outlet but also significantly improves the system's energy efficiency.

[0115] In some embodiments, the first purification component 2 further includes a flow equalization plate 24, which is disposed between the first air inlet 11 and the first purification module 21. The flow equalization plate 24 is used to evenly distribute the outdoor fresh air introduced into the first air inlet 11.

[0116] In this embodiment, the first purification component 2 is equipped with a flow equalization plate 24, which can effectively improve airflow distribution and enhance the overall efficiency of the purification system. Specifically, the flow equalization plate 24 is located between the first air inlet 11 and the first purification module 21 to distribute the incoming fresh outdoor air, avoiding situations where the local wind speed is too high or too low. This also makes the operation of the fan 4 more stable, thereby reducing noise radiation.

[0117] This embodiment, by setting a flow equalization plate 24 in the first purification component 2, can effectively improve the air intake distribution of fresh outdoor air and avoid situations where the local wind speed is too high or too low. This not only helps to improve the efficiency of the entire purification system, but also makes the operation of the fan 4 more stable, thereby greatly reducing noise radiation and creating a clean and stable air environment and comfortable and quiet working conditions.

[0118] The following example can be derived from the above technical solutions:

[0119] The air purification and disinfection system for operating rooms includes a first housing 1, a first purification component 2, a second purification component 3, a fan 4, a coil assembly 5, a first active composite particle generator 6, a pipeline assembly 7, a diffuser assembly 8, and a control unit 9. The first purification component 2, the second purification component 3, the fan 4, the coil assembly 5, and the first active composite particle generator 6 are placed inside the first housing 1.

[0120] Outdoor fresh air is driven by fan 4 and enters the first housing 1 through the first air inlet 11. After passing through the flow equalization plate 24, the incoming air is evenly distributed through the first purification module 21. The first purification module 21 uses electrostatic adsorption to initially intercept and filter particulate matter in the outdoor fresh air. The air after interception is then subjected to secondary interception and filtration by the second purification module 31. The filtered air then passes through the first coil 51 and the second coil 52 for dehumidification, heating, and cooling regulation. It then passes through the first active composite particle generator 6, where several of the first active composite particle generators 6 generate highly efficient sterilization and disinfection active composite particles, which are then carried into the pipeline assembly 7. The pipeline assembly 7 includes a first pipeline 71 and a second pipeline 72. The air in the second pipeline 72 is divided into two streams, flowing through the third purification module 841 and the fourth purification module 851, respectively. The airflow from the third purification module 841 and the fourth purification module 851 carries the active composite particles with disinfection and sterilization functions generated by the second active composite particle generator 843 and the third active composite particle generator 853. After being uniformly scattered by the damping scattering net 86, the particles flow into the operating room.

[0121] The air in the operating room passes through the return air duct in the operating room and enters the first housing 1 through the second air inlet 12, and then recirculates into the operating room.

[0122] The first purification module 21 is equipped with a first energy storage module 22. In the event of an emergency power outage, the first purification module 21 may fail due to power failure, and the particles adsorbed on the first purification module 21 may fall off. The first energy storage module 22 can maintain the power supply to the first purification module 21 for a short time in the event of a power outage, thus preventing the particles adsorbed on the first purification module 21 from failing due to power failure.

[0123] The first purification module 21 is equipped with a first particle sensor 23 at its rear end. The first particle sensor 23 can detect the concentration of particulate matter in the air passing through the first purification module 21. The filtration efficiency of the first purification module 21 can be determined based on the particulate matter concentration collected by the first particle sensor 23. The control unit 9 controls and reminds the user if the filtration efficiency is lower than the critical value. If so, the user will be reminded to clean or replace the module.

[0124] The second purification module 31 is equipped with a second particle sensor 33 at its rear end. The second particle sensor 33 can detect the concentration of particulate matter in the air passing through the second purification module 31. The filtration efficiency of the second purification module 31 can be determined based on the particulate matter concentration collected by the second particle sensor 33. The control unit 9 can then control and provide reminders. If the filtration efficiency is lower than a critical value, it will remind the user to clean or replace the module.

[0125] The first purification module 21 is the primary filter for outdoor fresh air. Since outdoor fresh air has relatively poor air quality, the first purification module 21 will have a shorter lifespan for cleaning or replacement. The second purification module 31 filters indoor return air, which has relatively better air quality, and therefore has a longer lifespan for cleaning. The control unit 9 intelligently adjusts the on / off state of the first and second purification modules 21 and 31 based on the air particulate matter concentration fed back by the first and second particle sensors 23. This ensures that the first and second purification modules 21 and 31 maintain similar or near-identical cleaning and lifespan times, reducing labor costs for after-sales cleaning and maintenance.

[0126] The air passing through the first purification module 21 and the second purification module 31 is intelligently regulated by the control unit 9 via the first temperature and humidity sensor 57 and the second temperature and humidity sensor 58. The filtered air is cooled, dehumidified, and heated by the first coil 51 and the second coil 52. The first coil 51 is connected to the first water inlet pipe 55 to cool and dehumidify the air flowing through it, and the second coil 52 is connected to the first water return pipe 56 to heat the air flowing through it.

[0127] The air distribution assembly 8 includes a first electric air valve 844, a second electric air valve 854, a third purification module 841, a fourth purification module 851, a third energy storage module 842, a fourth energy storage module 852, a second active composite particle generator 843, a third active composite particle generator 853, a second housing 81, and a damping scattering net 86.

[0128] The airflow from the first active composite particle generator 6 is split into two streams. One stream flows through the first branch 82, passing through the first electric air valve 844, the third purification module 841, the second active composite particle generator 843, and the third particle sensor 845, before entering the second chamber 81. The other stream flows through the second branch 83, passing through the second electric air valve 854, the fourth purification module 851, the third active composite particle generator 853, and the fourth particle sensor 855, before entering the second chamber 81. After mixing, the airflow is evenly scattered by the damped scattering net 86 before flowing into the operating room.

[0129] The first electric air valve 844 and the second electric air valve 854 are open by default. When the third particle sensor 845 or the fourth particle sensor 855 detects an abnormal particulate matter index, it indicates that the third purification module 841 and the fourth purification module 851 have failed. The corresponding first electric air valve 844 or second electric air valve 854, controlled by the control unit 9, will automatically close to prevent the concentration of particulate matter in the operating room from exceeding the standard due to the failure of the purification module.

[0130] The third purification module 841 is equipped with a third energy storage module 842, and the fourth purification module 851 is equipped with a fourth energy storage module 852, which can prevent the adsorbed particles from falling off due to the purification module's failure due to a sudden power outage.

[0131] Unlike existing technologies, this utility model includes a first housing 1, a first purification component 2, a second purification component 3, a fan 4, a coil component 5, a first active composite particle generator 6, a pipeline component 7, a diffuser component 8, and a control unit 9.

[0132] The first purification component 2, the second purification component 3, the fan 4, the coil assembly 5, and the first active composite particle generator 6 are housed within the first enclosure 1. The first purification component 2 and the second purification component 3 employ a multi-stage filtration system. First, outdoor fresh air is initially intercepted, and then the initially treated air undergoes secondary filtration. This effectively removes particulate matter, harmful gases, and other pollutants, ensuring extremely high air cleanliness at the air outlet and providing a hygienic and safe airflow guarantee for the surgical environment. The fan 4 provides airflow drive for the entire system, delivering the purified air to the coil assembly 5. The coil assembly 5, through temperature and humidity regulation, not only ensures that the outlet air meets the comfort requirements of the operating room but also effectively inhibits the growth of bacteria, viruses, and other microorganisms. The first active composite particle generator 6 releases highly oxidizing disinfectant factors, continuously sterilizing the air about to enter the ductwork, further enhancing the air disinfection effect and effectively compensating for the limitations of physical filtration.

[0133] Furthermore, this invention ensures emergency power supply during power outages through the first energy storage module 22, the second energy storage module 32, the third energy storage module 842, and the fourth energy storage module 852. Intelligent functions such as fault monitoring are achieved through integrated control via the control unit 9, significantly improving anti-interference capabilities and reliability. Simultaneously, energy-saving measures such as electrostatic dust removal filters and waste heat recovery significantly enhance the system's energy efficiency and economy.

[0134] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this utility model, this should not limit the scope of patent protection of this utility model. Any technical solutions resulting from equivalent structural or procedural substitutions or modifications made based on the essential concept of this utility model and utilizing the content described in the text and drawings of this utility model, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this utility model.
