Description

Technical Field

[0001] The utility model relates to a household appliance, in particular to a purification device. Background Art

[0002] Range hoods have become one of the indispensable kitchen appliances in modern families. Range hoods work based on the principle of fluid dynamics, using a centrifugal fan installed inside the range hood to absorb and exhaust oil fumes, and using a filter to filter out some grease particles.

[0003] At present, users' demand for cooking is not limited to the kitchen. They also cook at the dining table, island counter and other places in the living room, such as using some popular small appliances to cook hot pot and snail noodles. The existing range hoods with built-in fans are not suitable for installation in restaurants and other areas closer to human activities due to their large size and relatively high noise, and require a separate outdoor exhaust duct; and some range hoods using technologies such as internal circulation are installed in restaurants, but due to the accumulation of oil and odor in the filter element and the short replacement cycle, the restaurant's air is polluted again, affecting the actual user experience, so that the purchase of high-end range hood products fails to achieve the expected experience improvement, which in turn affects word of mouth.

[0004] If purification equipment is installed in every space, the cost will be relatively high. In addition, in addition to solving cooking needs, there will be air purifiers and fresh air purifiers in the living room and other places, so multiple appliances will take up space and be costly.

[0005] Therefore, there is room for further improvement. Utility Model Content
