Description

Fume collecting hood and fume absorbing device Technical Field The utility model relates to the technical field of kitchen appliances, in particular to a smoke collecting hood and a smoke absorbing device. Background The working principle of the fume extractor is that the blower works, under the suction force generated by the blower work, fume enters the fume inlet channel through the air inlet, then enters the air box, and finally is discharged into the public fume exhaust pipeline through the fume exhaust pipeline. The air inlet of the range hood is provided with a filter screen for filtering oil drops, water mist and the like in the oil smoke generated by cooking, so that the oil drops, the water mist and the like entering the range hood are reduced. After long-time use, the interior of the range hood can accumulate oil stains. In practical application, it is found that some oil dirt accumulated in the range hood drips onto the filter screen, and sometimes the oil dirt drips down to pass through holes on the filter screen to directly drip into food in a kitchen range surface or a pot, so that user experience is seriously affected. Disclosure of utility model One of the technical problems to be solved by the utility model is to provide the fume collecting hood, which can guide the greasy dirt which drops down onto the oil screen on the inner wall of the hood body, reduce the possibility that the greasy dirt passes through the fume inlet downwards and improve the user experience. The second technical problem to be solved by the utility model is to provide the oil fume suction device, which reduces the possibility that oil stains pass through the first fume inlet downwards and can improve user experience. The first technical problem is solved by the following technical scheme: The fume collecting hood comprises a hood body provided with an air inlet, and an oil net which is arranged at the air inlet and covers the air inlet, wherein the oil net is provided with a plurality of first fume inlet holes; The edge of one end of the oil guiding shielding part along the left-right direction is a first edge, the edge of the first edge and the edge of the corresponding first smoke inlet hole form a second smoke inlet hole communicated with the first smoke inlet hole along the vertical direction, and the other edges of the oil guiding shielding part are enclosed on the periphery of the corresponding first smoke inlet hole and are in sealing connection with the oil screen. Compared with the background technology, the fume collecting hood has the following beneficial effects: In the oil smoke rising process, the oil smoke enters the cover body through the first smoke inlet hole on the oil screen, and when the oil smoke rising to the upper part of the oil screen is condensed to form liquid drops such as oil drops and the water drops drop down, the liquid drops can drop onto the oil guide shielding part, and the oil guide shielding part can block the liquid drops to downwards pass through the first smoke inlet hole and drop onto the kitchen table surface. Because the oil guiding shielding part is arranged from front to back in a downward sloping way, liquid drops falling onto the upper surface of the oil guiding shielding part can flow backwards under the flow guiding effect of the oil guiding shielding part, and because the oil guiding shielding part forms one end edge of the second smoke inlet hole with the corresponding first smoke inlet hole edge, other edges of the oil guiding shielding part are surrounded on the periphery of the corresponding first smoke inlet hole and are in sealing connection with the oil screen, the probability that oil stains falling onto the upper surface of the oil guiding shielding part fall into the first smoke inlet hole is greatly reduced. Because the oil guide shielding part is located above the corresponding first smoke inlet hole, and the oil guide shielding part only forms a second smoke inlet hole with the corresponding first smoke inlet hole along the vertical direction, other edges of the oil guide shielding part are enclosed to the periphery of the corresponding first smoke inlet hole and are connected with the oil screen in a sealing manner, so that the oil guide shielding part has the effect of shielding the corresponding first smoke inlet hole, when the noise radiated from the inside of the cover body is radiated to the oil guide shielding part, reflection can occur under the effect of the oil guide shielding part, the effect of the noise radiated outwards from the inside of the cover body through the first smoke inlet hole is greatly reduced, and therefore the noise of the oil absorption smoke device is effectively reduced, and the user experience is improved. In one embodiment, the oil screen is arranged in a downward inclination mode from left to right or from right to left; The other end edge of the oil guide shielding part along the left-right direction is a second edge, an
