And an air inlet of the suction fan is positioned within the radius range of the filter screen disc. Flying smoke dust is sucked and removed through the suction fan, Chinese doughnut leaves in the smoke dust are filtered through the filter screen disc, the Chinese doughnut leaves are prevented from blocking an air inlet of the suction fan, the filter screen disc is rotationally arranged, and when the suction fan sucks air, flowers and leaves left on the filter screen disc can fall off when leaving an area corresponding to the air inlet of the suction fan, so that the flowers and leaves are prevented from entering the air inlet of the suction fan. Therefore, along with the rotation of the filter screen disc, the filter screen piece which is not blocked by the Chinese hemp leaves is kept to correspond to the air inlet of the suction fan all the time.
