Oil screen assembly and range hood

The invention belongs to the technical field of range hoods, and particularly relates to an oil screen assembly and a range hood. The range hood aims at solving the problem that in the related technology, the oil smoke suction efficiency of a range hood is low. According to the oil screen assembly and the range hood, the oil screen assembly comprises an oil screen plate and a flow dividing piece, and the oil screen plate is provided with a first main smoke inlet, an auxiliary smoke inlet and a second main smoke inlet which are sequentially arranged at intervals in the length direction of the oil screen plate. The flow dividing piece is arranged on the smoke outlet side of the oil screen plate and right faces the auxiliary smoke inlet, and a first auxiliary smoke inlet channel and a second auxiliary smoke inlet channel are formed between the flow dividing piece and the oil screen plate. By means of the arrangement, under the condition that the suction force of the draught fan to the auxiliary smoke inlet is no
