Atmosphere sampler with protective structure

The utility model discloses an atmosphere sampler with a protective structure, which comprises a body, heat dissipation ports are arranged on the left side and the right side of the body, first sliding chutes are arranged at the upper ends of the heat dissipation ports, a concentric-square-shaped frame is mounted in the body and positioned on the inner sides of the heat dissipation ports, and a baffle is movably mounted in the concentric-square-shaped frame. According to the air sampler disclosed by the utility model, when the air sampler is detected in an environment with relatively high humidity, the push block is pushed to push the connecting rod to move, so that the baffle fixed with the connecting rod is pushed to the rear end of the heat dissipation opening, and the heat dissipation opening is shielded and protected through the baffle, so that moisture is prevented from entering the air sampler to influence the accuracy of a sampling detection result.
