Abstract
A fan structure includes a housing extending along a first axis, a fan blade rotatably disposed within the housing and along the first axis, and a gear assembly. The gear assembly includes a sun gear coaxially arranged with the fan blade, a ring gear disposed on an inner wall of the housing, a plurality of planet gears meshing between the sun gear and the ring gear, and a decorative plate mounted on the planet gears. When the fan blade is driven to generate airflow, rotation of the fan blade drives the sun gear to rotate, the rotating sun gear causes the planet gears to revolve between the sun gear and the ring gear, and the revolving planet gears drive the decorative plate to rotate.

A fan structure, comprising:
- a housing arranged along a first axis,
- a fan blade rotatably arranged within the housing and along the first axis, and
- a gear assembly including:
- a sun gear coaxially arranged with the fan blade,
- a ring gear arranged on an inner wall of the housing,
- a plurality of planet gears meshing between the sun gear and the ring gear, and
- a decorative plate arranged on the planet gears,
- wherein when the fan blade is driven to generate airflow, the driven fan blade rotates the sun gear, the rotating sun gear drives the planet gears to revolve between the sun gear and the ring gear, and the revolving planet gears drive the decorative plate to rotate.
A fan assembly, comprising:
- a housing;
- a fan rotor rotatably arranged within the housing;
- a sun gear coaxially connected to the fan rotor;
- a ring gear secured relative to the housing;
- a plurality of planet gears meshing with the sun gear and the ring gear;
- a transmission gear meshing with the planet gears;
- and
- a decorative plate coupled to the transmission gear,
- wherein rotation of the fan rotor drives the sun gear to rotate, the rotation of the sun gear propels the planet gears to revolve between the sun gear and the ring gear, the revolving planet gears drive the transmission gear to rotate, and the rotating transmission gear drives the decorative plate to rotate about the first axis.
