Description

Technical Field

[0001] The utility model relates to an oil fume filtering device, in particular to an oil net device, and in particular to a range hood applying the oil net device. Background Art

[0002] The range hood is a kitchen cleaning appliance that purifies the kitchen environment. The range hood is installed above or on the side of the kitchen stove. The range hood can quickly extract the fumes and discharge them outdoors to prevent the fumes from spreading indoors, thereby purifying the indoor air. At present, most range hoods are matched with double-eye stoves. The negative pressure area formed by the fan of the range hood is fixed, the negative pressure size is fixed, and the amount of fumes adsorbed and discharged is also fixed. However, the fumes generated by the stove vary with different usage scenarios. For example, when one side of the stove is in use, the stove on that side generates fumes, but the existing range hoods fixedly suck the entire stove area, so half of the inhaled air is clean and invalid, which wastes the exhaust capacity of the range hood itself and affects the exhaust effect of the range hood.

[0003] Existing range hoods have been improved to address the above-mentioned problems, as shown in the Chinese utility model "A range hood" with patent number CN202322235328.5 (authorization announcement number CN220287544U), which includes a range hood body, a smoke hood and an oil net device. The oil net device includes an outer oil net, an inner oil net and a guide rail assembly. The guide rail assembly connects the outer oil net and the inner oil net. The guide rail assembly includes a guide rail and a guide post. The guide rail is arranged on a side surface of the outer oil net close to the oil fume channel. The guide post is connected to the inner oil net. The guide post can move in the guide rail, so that the inner oil net can move relative to the outer oil net to change the relative overlap or stagger of the mesh holes of the inner oil net and the mesh holes of the outer oil net.

[0004] Although the above-mentioned range hood can achieve the effect of efficient smoke extraction through the oil net device, after the range hood is used for a long time, the oil net device will have oil stains that need to be cleaned, especially the guide rail assembly in the oil net device. The guide rail is arranged between the outer oil net and the inner oil net. Solidified oil stains may accumulate in the guide rail, making it impossible for the guide column to move smoothly in the guide rail, thereby affecting the effect of the inner oil net moving relative to the outer oil net; and the guide rail of the oil net device is connected to the outer oil net through fasteners. Therefore, the user needs to use tools to disassemble the guide rail for cleaning, which is inconvenient for the user to operate and may cause the oil net device to be incompletely cleaned, thereby affecting the user's respiratory health.
