Abstract

The accumulated dust sampling head comprises a sampling shell with a hollow interior and two open ends, a port of the sampling shell is connected with a hose, the hose can completely seal the port, a sieve plate is arranged in a cavity of the sampling shell, and the sieve plate is connected with the sampling shell. The sieve plate is in seamless connection with the inner wall of the sampling shell, and the sieve plate can move or rotate along the center line of the sampling shell. According to the scheme, dust samples in the indoor environment can be effectively collected, and dust microorganisms can directly enter the culture dish through the six-stage sieve pore impact type microorganism sampler, so that the limitation of the existing dust microorganism sampling method is solved, the cross contamination among the samples is avoided, and the sampling accuracy and efficiency are improved.
