Description

Technical Field

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

[0002] Range hoods have become one of the indispensable kitchen appliances in modern families. Range hoods are mainly divided into top suction type and side suction type. Among them, the side suction range hood uses the principle of vortex wind pressure to absorb oil smoke in the form of an arc, which has a better effect of absorbing oil smoke and will not collide with the user's head, and the user experience is better. At present, most range hoods are matched with double-eye stoves. After the range hood is turned on, the entire oil net air inlet area is evenly aired, that is, the range hood sucks the entire stove area. However, in the actual use of the range hood, one side of the stove is often used, which produces more oil smoke, while the other side has less oil smoke, or even no oil smoke. This results in one side of the range hood sucking in clean and invalid air, wasting the range hood's own exhaust capacity and energy, thus affecting the user's experience.

[0003] In view of the above problems, existing range hoods have been improved. For example, a Chinese invention with application number CN201810541690.X (application publication number CN110207200A) discloses an oil net device for a range hood, comprising an outer oil net and at least two movable oil nets, wherein the at least two movable oil nets are respectively slidably arranged on both sides of the outer oil net in a horizontal direction, wherein the movable oil net is fixedly connected with a shift block by means of screws, and the movable oil net is moved by moving the shift block; when the movable oil net is moved to one side of the outer oil net in a horizontal direction, the second air inlet hole on the movable oil net overlaps with the first air inlet hole on the outer oil net, and when the movable oil net is moved to the other side of the outer oil net in a horizontal direction, the second air inlet hole on the movable oil net is staggered with the first air inlet hole on the outer oil net; thereby, the user can adjust the air inlet area of ​​the left and right regions of the oil net according to the oil smoke generated by the left and right stoves, and thereby indirectly adjust the air inlet volume of the left and right regions of the oil net.

[0004] Although the above-mentioned oil net device can independently adjust the air intake volume of the left and right areas of the oil net, after long-term use, the outer oil net and the movable oil net often have oil stains that need to be cleaned, and the movable oil net is fixedly connected to the shift block by screws, and the user cannot remove the movable oil net for separate cleaning, or needs to use tools to remove the movable oil net for cleaning, which results in incomplete cleaning of the oil net device, or the oil net device is inconvenient to disassemble and install. Therefore, the oil net device affects the user experience of the range hood. If the oil net is not thoroughly cleaned, it will also affect the user's respiratory health. For this reason, further improvements are needed to the oil net device of the range hood. Summary of the invention
