Description

Filter screen assembly and range hood Technical Field The utility model relates to the technical field of oil fume suction equipment, in particular to a filter screen assembly and an oil fume suction machine. Background The fume exhauster, also called fume exhauster, is one kind of kitchen appliance capable of purifying kitchen environment and capable of exhausting fume from indoor to outdoor, and consists of fume collecting cavity and casing and enclosing board assembly. The range hood is generally arranged above a kitchen range, can rapidly pump away waste generated by combustion of the range or oil smoke harmful to human bodies in a cooking process, is discharged outdoors, can condense and collect the oil smoke, reduces pollution, purifies air, and has the functions of gas protection and explosion prevention. The cooking temperatures of the kitchen are different, the content of the generated oil smoke is different, and most of the oil smoke generated by cooking contains substances harmful to human health. For example, when the cooking temperature is low, the generated oil smoke is mainly steam and a small amount of volatile odor molecules, when the cooking temperature is high, the generated oil smoke in the kitchen is mainly volatile organic matters and a small amount of tiny liquid drop particles, such as PM2.5, PM2.5 refers to particles with the aerodynamic equivalent diameter less than or equal to 2.5 microns, and the particles are also called fine particles or lung-entering particles, have long residence time in the atmosphere and long transmission distance, contain various toxic and harmful substances and have serious influence on human health and environment, and when the cooking temperature is extremely high, the generated oil smoke in the kitchen contains a large amount of solid particles and other harmful substances. In order to ensure the health of users, the range hood usually adopts a filter screen installation mode to filter the oil smoke generated in a kitchen so as to reduce the emission of harmful substances.
