Description

Technical Field

[0001] This utility model relates to a desktop range hood, and more particularly to a desktop range hood with an oil cup. Background Technology

[0002] Current desktop range hoods generally consist of a main body and a base. The main body has a smoke extraction channel with a suction port and an exhaust port at each end. An oil fume separator is located at the suction port, and an oil drain hole is located below the separator. An oil cup is located inside the base, and the oil drain hole is connected to the inside of the oil cup via an oil guide pipe. When the sucked-in oil fumes collide with the oil fume separator, oil particles remain on the separator. After accumulating to a certain amount, they drip into the oil drain hole and then flow into the oil cup through the oil guide pipe. Because the oil is transported over a long distance, it easily clogs the pipes, making cleaning difficult. Utility Model Content
