[0002] Nowadays, people can handle more and more food at home. In the process of indoor cooking, a large amount of oil smoke is easily generated, which can cause harm to the human body. Therefore, when decorating the kitchen, it is necessary to install a range hood to extract the harmful oil smoke generated during the cooking process and discharge it to the outside to ensure that the impact of indoor cooking is small.

[0003] The existing range hoods are simple, beautiful and easy to use in appearance, but in fact they still have some defects. The oil net of the range hood is often installed at the air inlet position to filter the inhaled oil smoke, but the inverted cone oil nets of some range hoods are often installed under the main body of the range hood by screws. When disassembling and assembling the oil net, multiple screws need to be disassembled and assembled before it can be cleaned. This makes it inconvenient for users to manually remove it, and they cannot be cleaned frequently. After long-term use, a lot of grease that is difficult to clean accumulates, which brings a bad user experience. Utility Model Content
