[0002] As people's requirements for quality of life continue to increase, environmental protection is increasingly valued. The detection of air environment is inseparable from gas sampling detection. The gas sampling device is used to sample the air in the environment for subsequent detection of the concentration in the air.
[0003] Existing gas sampling devices for environmental detection generally do not have a filtering and blocking structure for larger sand and gravel particles and flying insects that may enter with the suction force when the gas is absorbed. The filtering and blocking structure is not easy to clean, and the sampling structure and the storage structure are generally fixedly connected, which is not convenient for multiple sampling of different samples. Therefore, the utility model provides a gas sampling device for environmental detection. Utility Model Content
