Baffle structure for improving sampling efficiency of impact type air microorganism sampler

The utility model provides a baffle structure for improving the sampling efficiency of an impact type air microorganism sampler. The device comprises a baffle, a first supporting ring and a second supporting ring, the baffle is of a semi-hollow cylinder structure. The baffle comprises a baffle top end, a baffle bottom end and a baffle side wall; the left end of the side wall of the baffle extendsoutwards along the bottom end of the baffle to form a first clamping plate. The right end of the side wall of the baffle extends outwards along the bottom end of the baffle to form a second clamping plate. The first clamping plate and the second clamping plate are used for clamping the outer wall of the impact type air microorganism sampler; an opening allowing a spring drag hook on the impact type air microorganism sampler to penetrate through is formed in the side wall, close to the middle position of the bottom end of the baffle, of the baffle; the first supporting ring and the second supporting ring are fixedly ar
