Indoor wind enters the fan body 1 from the air inlet 3 and is finally output from the air outlet 4. At the same time, the servo motor 53 on the mounting tube 51 is started. The rotation of the servo motor 53 drives the rotation of the first gear 54. Because the slider 56 on the brush 57 is limited by the sliding of the groove 55 on the inner wall of the mounting tube 51, and the first gear 54 is meshed with the second gear 58, the brush 57 rotates and rubs on the surface of the protective net 52, temporarily cleaning the dust and impurities adhering to the protective net 52, thereby ensuring the normal circulation of wind. At this time, when the fan body 1 is in use, it is not easy for impurities and foreign objects to enter the interior of the fan body 1, causing erosion and damage to its internal components, thereby affecting the normal use of the fan body 1, thereby ensuring the use effect and work efficiency of the fan body 1.

[0030] Reference Figure 1 , Figure 2 and Figure 3As shown, in this embodiment: a stabilizing plate 510 is fixedly connected to the surface of the servo motor 53, and the stabilizing plate 510 is rotatably connected to the surface of the rotating rod 513.

[0032] Reference Figure 1 and Figure 4 As shown, in this embodiment: the protective device 6 includes two assembly plates 61, the two assembly plates 61 are respectively fixedly connected to the two sides of the surface of the air outlet 4 of the fan body 1, the inner walls of the two assembly plates 61 are respectively clamped with mounting plates 62, the surface of the mounting plates 62 is fixedly connected with a mesh plate 63, the surfaces of the two assembly plates 61 are respectively penetrated and inserted with bolts 64, and the bolts 64 are threadedly connected to the surfaces of the mounting plates 62. When the air outlet 4 of the fan body 1 is protected, the mounting plate 62 fixedly connected on the mesh plate 63 is first clamped on the inner wall of the assembly plate 61 at the position of the air outlet 4, and then the bolts 64 are inserted into the surface of the assembly plate 61 and penetrated, and the bolts 64 are threadedly connected to the mounting plate 62. At this time, when the fan body 1 stops working, it is not easy for foreign matter and impurities to enter the inside of the fan body 1 from the air outlet 4, thereby better ensuring the normal use of the fan body 1, further extending the service life of the fan body 1, and improving the use effect of the fan body 1.

[0033] Reference Figure 1 and Figure 4 As shown, in the present embodiment: a reinforcement ring 67 is fixedly connected to the surface of one side of the mesh plate 63 close to the fan body 1, and the reinforcement ring 67 is a sponge ring. Through the setting of the reinforcement ring 67, it is not easy to produce a gap when the mesh plate 63 contacts and squeezes the surface of the fan body 1, thereby better preventing dust and foreign matter from entering the interior of the fan body 1, and the surfaces of the two assembly plates 61 are respectively provided with card grooves 65, and the inner walls of the card grooves 65 are clamped with card blocks 66, and the card blocks 66 are fixedly connected to the surface of the mounting plate 62.

[0034] Working principle: when the fan body 1 is in use, the motor body 2 is started to make the fan body 1 run, so that the indoor wind enters the fan body 1 from the air inlet 3 and is finally output from the air outlet 4. At the same time, the servo motor 53 on the mounting tube 51 is started. The rotation of the servo motor 53 will drive the rotation of the first gear 54. Because the slider 56 on the brush 57 is limited by the sliding groove 55 on the inner wall of the mounting tube 51, and the first gear 54 is meshed with the second gear 58, the brush 57 rotates and rubs on the surface of the protective net 52, and the dust and impurities adhering to the protective net 52 are temporarily cleaned, thereby ensuring the normal circulation of the wind. At this time, when the fan body 1 is in use, it is not easy for impurities and foreign matter to enter the interior of the fan body 1, causing erosion and damage to its internal components, thereby affecting the normal use of the fan body 1, thereby ensuring the use effect and work efficiency of the fan body 1.

[0035] When protecting the air outlet 4 of the fan body 1, firstly, the mounting plate 62 fixedly connected to the mesh plate 63 is clamped on the inner wall of the assembly plate 61 at the air outlet 4, and then the bolt 64 is inserted into the surface of the assembly plate 61 and penetrates through it, and the bolt 64 is threadedly connected to the mounting plate 62. At this time, when the fan body 1 stops working, it is not easy for foreign matter and impurities to enter the inside of the fan body 1 from the air outlet 4, thereby better ensuring the normal use of the fan body 1, further extending the service life of the fan body 1, and improving the use effect of the fan body 1.
