Abstract
A wind guiding cover, mounted on a fan, includes a rotating ring and a plurality of slats. The rotating ring is pivoted to the fan, and has an opening for an air flow generated by the fan to pass through. The rotating ring has a weight portion for offsetting the center of gravity of the rotating ring and normally maintaining the rotating ring at a static equilibrium position. The slats are pivoted to the rotating ring and arranged at the opening. When the fan operates, the slats are lifted by the air flow to open the opening. When the fan stops operating, the slats cover the opening under the gravity.

A wind guiding cover, mounted on a fan adapted to operate to generate an air flow, comprising:
- a rotating ring, rotatably disposed on the fan, and having an opening for the air flow to pass through, wherein the rotating ring has a weight portion for offsetting the center of gravity of the rotating ring and normally maintaining the rotating ring at a static equilibrium position;
- and
- a plurality of slats, pivoted to the rotating ring and arranged at the opening, wherein when the fan operates, the slats are lifted by the air flow so as to open the opening, and when the fan stops operating, the slats cover the opening due to the gravity.
