[0002] Air pollutants are substances released into the atmosphere by human activities or natural processes that have harmful effects on the environment or human health. To monitor atmospheric pollution, air sampling devices are often used to analyze the air and determine the extent of environmental contamination. This information is then provided to the relevant authorities so they can implement countermeasures and ensure a healthy living environment for all.

[0003] Patent application number 202222672470.5, titled "Sampling Device for Atmospheric Detection," proposes setting a positioning and fixing groove, a sampling tube, a lower air outlet pipe, an air pump, an air inlet pipe, an air outlet pipe, a valve, an external air outlet pipe, and a balloon. When the device is in use, the above structure can be used to sample the external air, and during the sampling process, the above structure can be used to discharge excess air inside the sampling tube, thereby improving the accuracy of sampling and preventing excessive air pressure inside the sampling tube, thereby increasing the quality of the device during use. At the same time, the existing device integrates sampling and collection and storage during use, thereby improving the degree of integration of the device; by setting a rain shield, when the device is used outdoors, the rain shield can be used to prevent rainwater from entering the air inlet pipe, thereby improving the accuracy of space detection and improving the quality of the device during use.

[0004] The inventor believes that the device cannot filter solid pollution in the atmosphere and can easily cause the suction pump to be blocked; the rain shield is not easy to store; and the air in the sampling tube is discharged through a balloon, resulting in a large amount of residual gas.
