Description

Technical Field

[0001] The utility model relates to a range hood head shell with an air guide structure. Background Art

[0002] The range hood is an indispensable appliance in the kitchen. Currently, most of the common range hoods are described in the patent document of Chinese Patent Publication No. CN216346489U. A head cavity is formed in the casing, and an air outlet is provided on the upper cover of the casing. The air outlet is connected to the oil fume exhaust duct. Driven by the fan, the oil fume can enter the head cavity from the air inlet below the range hood, and then be discharged along the oil fume exhaust duct through the air outlet.
