Abstract: The concealed rotary fan includes a rotary vane, a drive motor and a base. The drive motor is assembled into the base. The first end of the drive motor with the revolving shaft can be assembled onto a front support in a rotary state. The second end of the drive motor is fitted with a crank link, the first end of which can be driven to make the second end rotate. The second end is screwed onto a pivot point on to the base. When the revolving shaft of the drive motor rotates, the second end of the crank link will rotate synchronously, enabling the drive motor and revolving shaft to rotate axially and obliquely along with the rotary vane. Thus, the rotary fan allows automatic change of the outlet direction through the axial rotation of the rotary vane, the outlet area being expanded to improve the actual applicability.
