[0002] Viruses flow in the air in the form of aerosols. They need carriers to survive and have a limited survival time.

[0035] Reference Figure 1 to Figure 2 The virus and microorganism purification efficiency detection system of the first embodiment of the present application is used to detect the purification efficiency performance of the virus purification device. The virus and microorganism purification efficiency detection system includes an isolation room 100, a test cabin 200, a two-way flow fresh air system 110, an air duct device 300 and a control device 400.

[0036] The test cabin 200 is arranged in the isolation room 100; the two-way flow fresh air system 110 is respectively connected to the isolation room 100 and the test cabin 200, so that there is a preset positive pressure value between the isolation room 100 and the test cabin 200; the air duct device 300 is arranged in the test cabin 200, and the air duct device 300 includes a pipeline 310 and a pollutant generator 320, a fan component, a pre-sampling device 340, and a post-sampling device 350 arranged on the pipeline 310, the fan component is used to output air volume to the pipeline 310, the pipeline 310 is provided with a sample installation station 311, the pre-sampling device 340 and the post-sampling device 350 are respectively arranged upstream and downstream of the sample installation station 311, and the pollutant generator 320 is arranged upstream of the pre-sampling device 340; the control device 400 is respectively connected to the two-way flow fresh air system 110 and the air duct device 300 and is suitable for obtaining information collected by the pre-sampling device 340 and the post-sampling device 350.

[0037] It is understandable that the sample installation station 311 is a reserved position for installing the sample, and the purification efficiency of the virus and microorganism contaminants of the sample is calculated by collecting the pollutant concentrations at the front and rear ends of the sample. Specifically, the virus and microorganism purification efficiency of the tested machine is the percentage of the ratio of the difference between the concentration collected by the front sampling device 340 and the concentration collected by the rear sampling device 350 to the concentration collected by the front sampling device 340. In some embodiments, the test chamber 200 has a self-cleaning system, which is continuously turned on during the entire test to ensure safety.

[0038] Reference Figure 1 to Figure 2 The virus and microorganism purification efficiency detection system of the first embodiment of the present application ensures the test environment through the isolation room 100, the test chamber 200 and the two-way flow fresh air system 110. The pollutant generator 320, the fan component, the front sampling device 340, and the rear sampling device 350 are integrated on the pipeline to form a simple detection device. By placing the virus and microorganism purification equipment at the sample installation station 311, the control device 400 is used to control the operation of the pollutant generator 320 and the fan component, and after the test is completed, the virus and microorganism purification efficiency of the tested machine can be obtained efficiently and quickly based on the concentration data collected by the front sampling device 340 and the rear sampling device 350.

[0039] In some embodiments of the present application, the air duct device 300 includes a rectifier 360, a front static pressure ring 370 and a rear static pressure ring 380, the rectifier 360 is arranged between the pollutant generator 320 and the front sampling device 340, the front static pressure ring 370 is arranged between the rectifier 360 and the front sampling device 340, and the rear static pressure ring 380 is arranged between the sample installation station 311 and the rear sampling device 350. It can be understood that the rectifier 360 is used to eliminate the swirl of the gas and make the asymmetric speed uniform, the static pressure ring is installed before and after the sample, and the pressure resistance of the sample under a certain air volume is obtained by the pressure difference before and after the static pressure ring.

[0040] In some embodiments, the rectifier 360 is a star rectifier 360 to achieve a better uniformity effect.

[0041] In some embodiments of the present application, the fan component includes a variable frequency fan 331 and an air volume flow meter 332. The air volume flow meter 332 is disposed between the rectifier 360 and the front static pressure ring 370. The variable frequency fan 331 is suitable for adjusting the output air volume to meet the test requirements. It can be understood that the variable frequency fan 331 is a device that provides power to the air duct, and the air volume flow meter 332 is used to monitor the air volume flow in the pipeline 310.

[0042] In some embodiments of the present application, the air duct device 300 includes a first ultraviolet lamp 390 and a filter 313, the filter 313 is arranged at the front end of the pipeline 310, and the first ultraviolet lamp 390 is arranged near the front and rear ends of the pipeline 310. It is understandable that ultraviolet lamps are installed at the front and rear ends, so that the ultraviolet lamps are turned on after the test to purify the semi-automatic air duct. The front filter 313 can reduce the interference of external factors on the detection. In some embodiments, an observation window 312 is also provided on the pipeline 310, and the observation window 312 is arranged near the sample installation station 311. It is understandable that the front high-efficiency filter 313 is installed at the front end of the air duct pipeline 310, and then the air duct pipeline 310 is left with a pollutant access port connected to the pollutant generator 320, and a sealed glass window is left at the front and back of the sample installation station 311.

[0043] In some embodiments of the present application, the two-way fresh air system 110 includes a fresh air component 115, a first air intake duct 111, a second air intake duct 112, a first exhaust duct 113, and a second exhaust duct 114. The fresh air component 115 is connected to the isolation room 100 through the first air intake duct 111 and the first exhaust duct 113, respectively, and the fresh air component 115 is connected to the test chamber 200 through the second air intake duct 112 and the second exhaust duct 114. In some embodiments, control valves are provided in the first air intake duct 111, the second air intake duct 112, the first exhaust duct 113, and the second exhaust duct 114, and the control device 400 is suitable for controlling each control valve respectively.

[0044] It is understandable that the fresh air component 115 contains a high-efficiency filter 313, an activated carbon filter 313 and an ultraviolet lamp component, etc., so as to have intelligent control and purification and disinfection functions. Each ventilation pipeline 310 connected to the fresh air has an intelligent control valve, and the fresh air exhaust is controlled by setting the parameter intelligent control valve. It is more convenient to set the positive pressure parameter. In some embodiments, after the two-way flow fresh air system 110 is turned on, a 10Pa positive pressure is generated in the isolation room 100 and the test cabin 200.

[0045] In some embodiments, the air outlet is equipped with a fence to diffuse the air and reduce the wind speed.

[0046] In some embodiments of the present application, a stirring fan 210, a second ultraviolet lamp 220, a safety cabinet 230 and an incubator 240 are provided in the test chamber 200. It is understood that the stirring fan 210 is used to circulate air in the test chamber 200 into the purified air outlet pipeline 310, and the ultraviolet lamp included in the test chamber 200 can purify and disinfect the test chamber 200. The biological safety cabinet 230 and the incubator 240 are used for processing and cultivating viral microorganisms.

[0047] In some embodiments of the present application, a buffer room 116 and a shower room 117 are provided at the entrance of the isolation room 100. Protective equipment can be replaced in the buffer room 116, and individuals can be purified and disinfected in the shower room 117, thereby improving the system configuration.

[0048] In some embodiments of the present application, the control device 400 is installed outside the test cabin 200, and the self-purification system, pollutant generator 320, flow meter, front sampling device 340 and rear sampling device 350, front static pressure ring 370 and rear static pressure ring 380 of the test cabin 200 and the two-way flow fresh air system 110 are all connected to the control device 400. The opening and closing of all connected devices are controlled by the control device 400, and the air volume of the air duct 310, the pressure difference between the front static pressure ring 370 and the rear static pressure ring 380 and the operating time of each device are also displayed on the control computer interface.

[0049] When used specifically, the positive pressure system of the isolation room 100 is first turned on, and the entire test process forms a positive pressure between the cache isolation room 100 and the test chamber 200. The self-purification system of the test chamber 200, the ultraviolet lamp and the fan of the air duct 310 are turned on by the control computer, and the air volume of the air duct 310 is adjusted to the test requirements. After 30 minutes, the ultraviolet lamp in the cabin, the ultraviolet lamp and the fan of the air duct 310 are turned off, the sample is installed, and the virus microbial contaminants and the sampler are prepared, and the test preparation is completed. Then turn on the fan of the air duct 310 and adjust the air volume for trial operation, turn on the virus microorganism pollutant generation device to spray into the air duct 310, and after stable operation for 5 minutes, turn on the front sampling device 340 and the rear sampling device 350 to collect virus microorganism samples at the same time, collect parallel samples 3 times, turn off the pollutant generation device, turn on the ultraviolet sterilization lamp of the air duct 310 for 30 minutes, and the self-purification system of the test cabin 200 is running during the entire test process. After processing and detection, the concentration of the virus microorganism samples collected by the front sampling device 340 and the rear sampling device 350 is calculated. The virus microorganism purification efficiency of the tested machine is the percentage of the difference between the concentration collected by the front sampling device 340 and the concentration collected by the rear sampling device 350 and the ratio of the concentration collected by the front sampling device 340.
