Description

Technical Field

[0001] The utility model relates to the field of range hoods, and in particular to an oil filter structure and a range hood. Background Art

[0002] A range hood is an electrical appliance used in a home kitchen to remove oil fumes produced during cooking. It should not only perform its functional role well, but also have a decorative concept that integrates with the modern kitchen layout. After the oil fumes are inhaled, the filter in front of the fan blades will first filter out larger particles of oil, and then small particles of oil will adhere to the fan blades. The fan blades then rotate rapidly to throw the oil attached to the fan blades onto the separation plates on both sides, and finally flow into the oil cup.

[0003] Most range hood filter assemblies on the market are fixed to the smoke hood by screws. Currently, one end of the filter is fastened to the bottom of the smoke box by a buckle and the other end is fastened by screws. Therefore, when disassembling the filter (for example, when the user needs to clean the filter), a screwdriver is required to assist in turning the screws. During the long-term use of the range hood, oil stains are easily contaminated on the screws, which can easily cause the grooves on the screws to be blocked and inconvenient to disassemble. At the same time, when disassembling the filter, after the screws are unscrewed, the filter is easily dropped directly due to its own gravity, and may hit the stove or injure the person disassembling the filter. How to invent an oil filter structure and a range hood to improve these problems has become an urgent problem to be solved by those skilled in the art. Summary of the invention

[0004] In order to remedy the above deficiencies, the utility model provides an oil filter structure and a range hood, which aim to improve the problem that oil stains are easily contaminated on the screws, which easily leads to clogging of the grooves on the screws and makes disassembly inconvenient; and when disassembling and assembling the filter, the filter is easily dropped directly due to the influence of its own gravity after the screws are unscrewed.
