A method of cleaning a rotating screen of a built-in cartridge type range hood, the rotating screen of the built-in cartridge type range hood according to any one of claims 1 to 9 being mounted on a forward air disk of an impeller (14), characterized in that: the built-in chuck type range hood rotary filter screen synchronously rotates along with the impeller (14), based on high-speed rotation, oil smoke enters the impeller (14) through the meshes (7) and the meshes (9) which are uniformly distributed on the built-in chuck type range hood rotary filter screen under the action of negative pressure generated by the impeller (14), the mesh (1) which is uniformly distributed on the built-in chuck type range hood rotary filter screen can impact the oil smoke entering the impeller (14) through the front meshes (7) and the meshes (9) at high speed, the oil smoke particles are extruded and rubbed due to the high-speed impact action, the oil smoke particles are continuously gathered and grown up by the extrusion and friction action, the intercepted oil smoke particles are thrown away under the action of centrifugal force generated by the high-speed rotation of the impeller (14), thereby greatly reducing the opportunity that the oil smoke enters the impeller (14), effectively reducing the pollution of the impeller (14) by the oil smoke, and being more beneficial to the separation of, thereby improving the degree of grease separation.
