Abstract
This utility model discloses a kitchen fume purification device, relating to the field of kitchen fume purification technology. The utility model includes a range hood body, with a fume extraction duct at the top and a fume inlet at the bottom. A control mechanism is located on the top right side of the range hood body. Rectangular holes are formed on the left and right sides of the fume inlet, with a fixing frame inside each rectangular hole. A fume filter is housed inside the fixing frame. A fixing block is located on the left side of the fixing frame, with a limit hole inside the fixing block. A fixing component is located at the bottom of the range hood body. The utility model uses a connecting plate to insert a limit rod into the limit hole, fixing the fixing frame in a fixed position. Conversely, when the uprights move away from each other, the movable block moves the limit rod out of the limit hole, thus facilitating the disassembly and installation of the fixing frame without damaging the fume filter during disassembly.
