The invention discloses a ducted fan structure and aims to provide a ducted fan structure beneficial to noise reduction, the ducted fan structure comprises a motor base and an annular outer cover, the motor base is located in the outer cover and located in the center of the bottom of the outer cover, a motor and a plurality of guide vanes are arranged on the motor base, one end of the motor is detachably connected with the motor base, and the other end of the motor is detachably connected with the guide vanes. The other end of the motor is an output end and is provided with a fan, the fan is located in the top of the outer cover and detachably connected with the output end of the motor, the multiple guide blades are evenly distributed in the circumferential direction of the motor base, the motor base is detachably connected with the inner side wall of the outer cover through the guide blades, the outer cover is provided with multiple hanging lugs, and the hanging lugs are fixedly connected with the outer side wall of the outer cover. The plurality of hanging lugs form a rectangular force unloading area corresponding to the motor, the left-right width of the force unloading area is larger than the diameter of the motor, and the up-down height of the force unloading area is larger than the height of the motor. The beneficial effects of the invention are that the motor vibration is reduced, and the purpose of reducing noise is achieved.
