The accumulated oil stains are attached to the inner wall of the smoke hood 1. When in use, the driving motor is energized and rotated, driving the driving frame 6 to rotate, thereby driving the arc-shaped scraper 7 to rotate, and the cleaning scraper 9 cleans the oil stains attached to the inner wall of the smoke hood 1 and makes it enter the guide groove 8. An annular collecting groove 10 is fixedly installed at the bottom of the smoke hood 1, and the oil stains inside the guide groove 8 enter the annular collecting groove 10 under the action of gravity.

[0031] An auxiliary guide structure is provided inside the guide groove 8, and the auxiliary guide structure includes a cleaning sliding block 11 slidably connected inside the guide groove 8, and the cross section of the cleaning sliding block 11 is set to be triangular, and an automatic winding device 12 is fixedly installed on the side of the arc scraper 7 away from the guide groove 8, and the automatic winding device is installed at the lower end of the arc scraper 7.

Until the lifting block 19 on the driving frame 6 contacts the matching block 17, the lifting block 19 pushes the matching block 17 upward, thereby pushing the control ring 14 to slide upward, so that the limiting groove 15 and the limiting block 16 are separated. The automatic winding device 12 pulls the cleaning sliding block 11 to slide in the direction away from the control ring 14 through the steel wire rope 13, and at the same time drives the control ring 14 to rotate on the connecting pipe 4 until the cleaning sliding block 11 slides to the lower end of the arc-shaped scraper 7.
