[0018] Beneficial effects

[0019] The utility model provides a fan control box with the following beneficial effects:

[0036] like Figure 3 As shown, the scraper 5 is fixedly connected to the end face of the rotating shaft 6 and is attached to the end of the heat sink 3 away from the rotating fan blade 7. The scraper 5 is located at the axis of the first heat dissipation hole 4 and is provided with a rectangular sliding cavity 8. The first magnet 9 is fixedly connected to the sliding cavity 8 at one end away from the first heat dissipation hole 4. The second magnet 10 is slidably connected to the inner wall of the sliding cavity 8. The second magnet 10 and the first magnet 9 have the same magnetic poles at one relative end.

[0037] The dredging rod 11 is fixedly connected to the outer wall of the second magnet 10 on the side close to the first heat dissipation hole 4. The dredging rod 11 is a truncated cone-shaped block with arc-shaped ends at both ends of the cross section.

[0038] A plurality of fixed slots arranged in a circle are provided at one end of the dredging rod 11 close to the first heat dissipation hole 4. The cleaning plate 13 is rotatably connected to the inner wall of the fixed slot and is in an arc shape. The two ends of the return spring 12 are respectively fixedly connected to the opposite wall surfaces of the dredging rod 11 and the cleaning plate 13.
