Description

Technical Field

[0001] The present invention relates to the technical field of air pollutant detectors, and in particular to an air pollutant AQI detection and analysis device. Background Art

[0002] The background of the atmospheric pollutant AQI detection and analysis device stems from the urgent need for air quality monitoring and environmental protection. With the acceleration of industrialization and urbanization, the problem of air pollution has become increasingly serious, posing a serious threat to public health and the ecological environment. In order to accurately assess the air quality status, timely warn of air pollution events, and provide a scientific basis for the formulation of environmental protection policies, atmospheric pollutant AQI detection and analysis devices came into being. These devices can monitor and analyze the concentrations of various pollutants in the air in real time, calculate AQI values, and provide the public with timely and accurate air quality information. At the same time, they also provide important data support for environmental protection departments.

[0003] After searching, the invention patent of Chinese patent number CN116400019B discloses a detection device for online monitoring of atmospheric pollutants, including a detection device, the input end of the detection device is fixedly connected with an air intake pipe, the detection device is connected with a conversion component, and the detection device is connected with a storage component; the conversion component is connected with a blowing component, and the blowing component is located below the storage component; the storage component is provided with a mounting component, and one end of the mounting component is connected to the conversion component; the mounting component is connected with a cleaning component, and the cleaning component is located in the storage component, and the cleaning component is connected with a connecting component. In the present invention, the staff can replace the sampling head according to the actual situation. At the same time, when the sampling head is replaced, the suction force generated by the air extraction is further used to seal the connection between the rotating plate and the air intake pipe, further avoiding air leakage of the device, so that the device can meet different usage requirements and indirectly improve the practicality of the device. Compared with the prior art, the invention patent with Chinese patent number CN116400019B solves the problem that when replacing the sampling head of the existing device, the staff still needs to manually replace it, which not only increases the workload of the staff, but also makes it impossible to ensure the sealing of the sampling head and the equipment during the installation process, further affecting the detection efficiency of the device.

[0004] However, in actual use of the above device, the device cleans the outside of the probe with a brush. However, when the probe is sampling, most of the dust and other impurities in the air adhere to the inside of the probe, and the cleaning effect is not good. Moreover, the cleaning process is carried out in the storage room, which causes the cleaned dust and other impurities to remain in the storage room, causing deviations in subsequent test data. Therefore, an atmospheric pollutant AQI detection and analysis device is proposed. Summary of the invention
