Various range hoods are usually equipped with air ducts for exhausting fumes.

[0003] When the range hood is far away from the smoke exhaust port, the air duct used will generally be longer. When the two ends of the air duct are respectively fixed to the range hood and the smoke exhaust port, the middle part of the longer air duct will naturally hang down. After a certain period of use, the gravity of the air duct may cause a certain looseness at the fixed positions at both ends, thereby reducing the overall installation firmness of the air duct.
