Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-4, the utility model provides an automatic axial-flow fan, including axial-flow fan body 1 and

dust screen

3, 3 joints of dust screen are at axial-flow fan body 1 front end, install servo motor 11 and fan blade 12 in the axial-flow fan body 1, install servo controller on the servo motor 11, fan blade 12 fixed connection is at the 11 outputs of servo motor, be provided with clearance mechanism 4 between the 11 outputs of servo motor and the dust screen 3, axial-flow fan body 1 joint has rail guard 2, servo motor 11 fixes in axial-flow fan body 1 through the mounting bracket.

The cleaning mechanism 4 comprises an inner bushing 41 and a cleaning brush 43, the inner bushing 41 is rotatably connected in the axial flow fan body 1 and is located at the front end of the axial flow fan body 1, a pair of linkage rods 42 is fixedly connected to the inner wall of the front end of the inner bushing 41, the cleaning brush 43 is fixedly connected to one side, close to the dust screen 3, of each linkage rod 42, the cleaning brush 43 abuts against the dust screen 3, a driving gear 44 is installed on the front side of the output end of the servo motor 11, an inner gear sleeve 46 is fixedly connected to the inner side wall of the inner bushing 41 and corresponds to the driving gear 44, a pair of transmission gears 45 are arranged between the inner gear sleeve 46 and the driving gear 44, the transmission gears 45 are meshed with the driving gear 44 and the inner gear sleeve 46, the diameter of the transmission gears 45 is larger than that of the driving gear 44, perforations penetrating through the transmission gears 45 are uniformly formed in the transmission gears 45, a pair of installation rods 47 is fixedly connected to the inner side wall of the axial flow fan body 1 and corresponds to the transmission gears 45, one end, which is close to the installation rods 47 are rotatably connected with the transmission gears 45 through a rotating shaft, when the driving gear 44 rotates along with the output end of the servo motor 11, the driving gear 45, the transmission gears 45 can rotate slowly, the driving gears 42 can rotate, and the driving gears can drive the cleaning brush to rotate along with the dust screen to rotate slowly, and the cleaning brush in the surface of the cleaning brush in the process, and the cleaning brush to reduce the cleaning brush 42.
