[0032] The support assembly 2 includes a support rod 201 and a support frame 202; one end of the support rod 201 is fixedly connected to the inner wall of the air duct 1, and the other end is fixedly connected to the outer wall of the support frame 202; the number of support rods 201 is 4, and they are evenly distributed on the outer wall of the support frame 202; the power assembly 3 is fixedly installed inside the support frame 202;

[0033] The power assembly 3 includes a motor 301, a rotating shaft 302 and a rotating cover 303; the motor 301 is fixedly installed inside the bracket frame 202; one end of the rotating shaft 302 is connected to the output end of the motor 301, and the other end is fixedly connected to the inner side of the rotating shaft, and the motor 301 drives the rotating cover 303 to rotate through the rotating shaft 302;

[0034] One end of the fan blade 4 is fixedly mounted on the outer wall of the rotating cover 303, and the rotating cover 303 drives the fan blade 4 to rotate;

[0035] The cleaning assembly 5 includes an upper sliding cover 501, a lower sliding cover 502, a top plate 503, cleaning cotton 504 and a tightening spring 505; the upper sliding cover 501 and the lower sliding cover 502 are respectively fixed on both sides of the fan blade 4; both ends of the upper sliding cover 501 and the lower sliding cover 502 are provided with bolt through holes; by installing fastening bolts in the bolt through holes, the upper sliding cover 501 and the lower sliding rod are connected; the top plate 503 is respectively movably installed inside the upper sliding cover 501 and the lower sliding cover 502;

[0036] One side of the cleaning cotton 504 is fixedly connected to the outer end surface of the top plate 503, and the other side of the cleaning cotton 504 is respectively against the two sides of the fan blade 4; the cleaning cotton 504 is soaked in degreasing cleaning liquid, which can degrease the fan blade 4.

[0037] The tension spring 505 is installed inside the upper sliding cover 501 and the lower sliding cover 502 respectively; one end of the tension spring 505 inside the upper sliding cover 501 is fixedly connected to the inner wall of the upper sliding cover 501, and the other end is fixedly connected to the inner end surface of the top plate 503 inside the upper sliding cover 501; one end of the tension spring 505 inside the lower sliding cover 502 is fixedly connected to the inner wall of the lower sliding cover 502, and the other end is fixedly connected to the inner end surface of the top plate 503 inside the lower sliding cover 502; the elastic force of the tension spring 505 can push the top plate 503, so that the cleaning cotton 504 can always be against the two sides of the fan blade 4. The two sides of the end of the fan blade 4 away from the output end of the power assembly 3 are provided with a limit plate 401, and the inner end surface of the limit plate 401 is respectively against the upper sliding cover 501 and the lower sliding cover 502. Prevent the upper sliding cover 501 and the lower sliding cover 502 from separating from the fan blade 4.

[0038] The traction assembly 6 includes a sleeve 601 and a traction spring 602; one end of the sleeve 601 is fixedly mounted on the outer wall of the rotating cover 303; one end of the traction spring 602 is fixedly mounted in the sleeve 601, and the other end is connected to the upper sliding plate and the lower sliding plate. When the fan blade 4 does not rotate or the centrifugal force of the cleaning assembly 5 is less than the elastic force of the traction spring 602, the traction spring 602 drives the cleaning assembly 5 to shrink and move on the fan blade 4 to clean the fan blade 4.

[0039] Two legs 101 are arranged on the outer wall of the air duct 1. The bracket facilitates the fan to be placed on a plane.

[0040] In this embodiment, the motor 301 first drives the rotating shaft 302 to rotate, thereby driving the rotating cover 303 and the fan blades 4 to rotate. During the rotation process, the upper sliding cover 501 and the lower sliding cover 502 are driven to move outward on the fan blades 4 by the action of centrifugal force, so that the cleaning cotton 504 soaked in degreasing cleaning liquid can wipe and clean the fan blades 4 to prevent oil smoke from adhering to the fan blades 4. When the fan stops rotating, the centrifugal force of the cleaning component 5 is less than the elastic force of the traction spring 602, so that the traction spring 602 pulls the upper sliding cover 501 and the lower sliding cover 502 to move inwardly of the fan blades 4, and then drives the cleaning cotton 504 to wipe the fan blades 4 again, achieving the effect of resisting oil smoke adhesion.

[0041] Specific embodiment 2, see Figure 5-6The difference between this embodiment and the first embodiment lies in the different structures of the fan blade 4 and the cleaning component 5, and the specific difference lies in: guide grooves 402 are provided on both sides of the fan blade 4, and sliding blocks 507 are provided on the lower end surface of the upper sliding cover 501 and the upper end surface of the lower sliding rod, and the sliding blocks 507 are slidably installed in the guide grooves 402; through the cooperation of the guide grooves 402 and the sliding blocks 507, the movement of the upper sliding cover 501 and the lower sliding cover 502 can be guided, avoiding the problem of random movement of the upper sliding cover 501 and the lower sliding cover 502 during the movement of the upper sliding cover 501 and the lower sliding cover 502, thereby increasing the movement stability of the upper sliding cover 501 and the lower sliding cover 502.
