It usually includes two or more blocking parts to separate the oil fume by multiple blocking. After the oil is separated, it will flow along the blocking part to the oil collecting mechanism under the action of gravity. However, after a certain period of time and under different cooking environments, part of the oil will adhere to the blocking part of the oil fume separator. At this time, the user needs to disassemble and clean the oil fume separator from the range hood.

The cleaning structure is composed of a lower purification combination structure, an upper purification combination structure and a oil scraping structure. The oil scraping sheet is designed according to the shape of the purification device. When cleaning, the oil scraping sheet is pushed to push the oil to the oil cup to achieve cleaning. Although this cleaning scheme does not need to disassemble the oil fume separator, it is not convenient to operate manually to push the oil scraping sheet.
