Description

Technical Field

[0001] The utility model relates to an oil fume purification device, in particular to a power board support frame component and an oil fume extractor. Background Art

[0002] Range hoods are essential appliances for people to absorb oil fumes when cooking. In recent years, multifunctional range hoods have become increasingly popular in the market.

[0003] For existing multifunctional range hoods, the power board is generally placed on the top of the fan frame and separated from the internal fume channel of the fan frame for easy maintenance and fume isolation. Some are fixed through holes with copper studs or ordinary plastic columns. On the one hand, the PCB support frame fixing method easily causes the components on the power board PCB to be vibrated by the fan operation, resulting in loose welding. On the other hand, similar machines have different configurations, such as different AC and DC drive modes, or different interfaces, which may lead to different PCB sizes and interfaces. After-sales service may be unable to install after receiving the maintenance materials. If multiple sets of mounting holes are opened on the top plate under the PCB, it is easy for fume and water vapor to spread from the bottom to under the PCB, resulting in an increased failure rate.
