Description

Technical Field

[0001] The utility model relates to the technical field of oil fume purifiers, in particular to a filtering device of an oil fume purifier. Background Art

[0002] A fume purifier, also known as a range hood, is a kitchen appliance that purifies the kitchen environment. It is installed above the stove in the kitchen and can quickly extract the waste from stove combustion and the fumes that are harmful to the human body produced during the cooking process and discharge them outdoors, reducing indoor pollution, purifying indoor air, and also has anti-toxic and explosion-proof safety protection functions.

[0003] During the use of the oil fume purifier, a filter needs to be added. The added filter can intercept large-particle impurities in the oil fume to reduce pollution to the environment. However, the filter mechanism of the oil fume purifier in the prior art can only filter out impurities in the oil fume, but cannot remove grease in the oil fume. Excessive grease adheres to the filter and is easy to drip from the surface of the filter. The user also needs to clean the dripping grease. In addition, the filter device in the existing oil fume purifier is not easy to disassemble for cleaning or replacement, which reduces the applicability of the device body. Therefore, it is necessary to improve the existing device to meet actual needs. Utility Model Content
