The range hood of this embodiment mainly comprises quick-witted case 100, fan subassembly 200, collection petticoat pipe subassembly and fender cigarette structure 400, and the theory of operation is: the fan assembly 200 generates negative pressure and transmits the negative pressure to the periphery of the smoke baffle structure 400 through the wind path, and then the smoke collecting hood 300 collects the smoke to make the smoke sucked into the range hood and centrifugally filtered by the oil screen assembly 410 and the impeller of the fan assembly 200, and finally the smoke is discharged through the smoke outlet at the upper end of the case 100.

Note that arrows in fig. 10 indicate the flow of the oil smoke.

The oil cup, the baffle and the oil screen of the existing range hood with the smoke baffle, such as the European range hood with the baffle, are respectively installed as independent parts, and if the range hood needs to be cleaned, the range hood can be completely disassembled after being disassembled for three times, which is very inconvenient; in addition, in the existing range hood with the smoke baffle, because the cavity bottom of the conventional smoke collecting hood is flat or is in a form that the middle is high and the two sides are low, the sump oil of the case 100 can easily flow out along the bottom surface of the smoke collecting hood 300, and finally the sump oil is collected to drop on a pot stove. This embodiment keeps off cigarette board structure 400, collection petticoat pipe subassembly and range hood can be fine solution above-mentioned problem. In the specific smoke baffle plate structure 400, the smoke collecting hood assembly and the range hood of the embodiment, the smoke baffle plate 401, the oil cup 402 and the oil screen assembly 410 are integrated and are integrally installed on the range hood, so that the trouble of repeated assembly and disassembly is avoided; meanwhile, the oil screen assembly 410 can be conveniently detached and cleaned; the locking mechanism 430 is controlled by the control mechanism 420 to be a controllable collision bead structure, so that the smoke baffle structure 400 is not shaken or inclined when being separated from the range hood, and the dirty oil is ensured to be stable and not to drip and spill; the top horizontal part of the smoke collecting cavity of the smoke collecting cover 300 is designed to be similar to an M shape, so that the dirty oil on the inner wall of the case 100 and the bottom of the smoke collecting cover 300 is completely collected towards the middle, drips on the smoke baffle 401 and flows into the oil cup 402, and the hearth is prevented from being polluted.
