Abstract: The present invention provides an improved built-in swing mechanism of a rotary fan. The mechanism includes a ball-and-socket support frame, arranged onto front wall of the main casing corresponding to the axle center of a drive motor and provided with a spherical supporting surface and a through-hole. A spherical abut seat is fastened at a front end of the drive motor is provided with a spherical abut surface that couples with the spherical supporting surface. A punch hole is placed at the center of spherical abut surface for the penetration of the axle center. A crank linkage element is assembled between rear end of the drive motor and the rear wall of the main casing. The first end of the crank linkage element can be driven to enable the oscillation of the second end. The second end is assembled at a rotary pivot corresponding to the main casing.

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.

Abstract: The present invention provides a cylindrical oscillating fan including a base, a cylindrical shell, a blade assembly, a drive motor and an oscillating drive device. The blade assembly and drive motor are assembled into the hollow groove of the cylindrical shell. The oscillating drive device is assembled into the base to drive the oscillation of the cylindrical shell. A support column is placed into the hollow groove. The top end is fastened to the top of cylindrical shell, and the bottom is fastened to the bottom of cylindrical shell. The support column is also screwed onto upper and lower support portions of the base for two-point positioning. The bottom of support column is linked to the oscillating drive device.

Abstract: The circumferential air conditioning fan includes a housing, centrifugal fan, and a drive motor. The housing has a containing space, and one end of the containing space has an air inlet, and the side of the containing space has a circumferential air outlet. A centrifugal fan is placed in the containing space that can be driven by drive motor, and the centrifugal fan has rotary diversion component. The first end is corresponding with the air inlet, and the second end is corresponding with the circumferential air outlet. A centrifugal fan is placed in the containing space that circulates airflow in the directions of circumferential air outlet. The circumferential air conditioning fan disclosed in the present invention can receive circumferential airflow in the circular direction, and further improve the quality of air and degree of comfort.
