The rotating mechanism includes a base, a driving gear, a connecting base, and a driving mechanism. A driving gear is arranged on the base, and the driving gear can rotate on the base. The connecting base is fixedly arranged on the driving gear. The fan body is arranged on the driving gear through the connecting base. The rotation of the driving gear drives the connecting base to rotate, thereby driving the fan body to rotate. The driving mechanism consists of a frame, a driving motor, and a driving gear. The driving motor and the driving gear are both arranged on the frame. The driving motor drives the driving gear to work. The driving gear meshes with the driving gear, and the rotation of the driving gear can drive the driving gear to rotate.

[0006] In the above-mentioned fan with an adjustable air outlet direction, an impeller is arranged in the fan body. The motor shaft of the control motor extends into the fan body and is connected to the impeller. The rotation of the control motor drives the impeller to rotate.

[0007] In the above-mentioned fan with an adjustable air outlet direction, the fan body is arranged in a square structure.

[0008] Compared with the prior art, in the blower with adjustable air outlet direction, the blower body is arranged on the rotating mechanism, and the rotation of the rotating mechanism can drive the blower body to rotate, realizing the function of adjustable air outlet of the blower body. BRIEF DESCRIPTION OF THE DRAWINGS
