FAN ASSEMBLY
First Claim
1. A fan assembly, comprising:
- a rack defining a first vent opening and a second vent opening aligned to the first vent opening;
a shield mounted in the rack and aligned to the first vent opening, the shield defining a circular opening corresponding to the first vent opening, a plurality of shielding pieces pivotally mounted in the circular opening, opposite ends of each of the plurality of shielding piece arc-shaped, the plurality of shielding pieces together forming a circle to shield the circular opening by gravity; and
a fan mounted in the rack and aligned to the second vent opening and the shield;
the fan adapted to drive air blowing towards the plurality of shielding pieces to rotate the plurality of shielding pieces to define an air passage between each two adjacent shielding pieces of plurality of shielding pieces, and the air passage adapted to have air flowing therethrough.

Abstract
A fan assembly includes a rack, a shield, and a fan. The rack defines a first vent opening and a second vent opening aligned with the first vent opening. The shield is mounted in the rack and aligned with the first vent opening. The shield defines a circular opening corresponding to the first vent opening. A plurality of shielding pieces are pivotally mounted in the circular opening. The plurality of shielding pieces together form a circular shield in themselves to cover the circular opening by gravity. The fan is mounted in the rack and aligned with the second vent opening and the shield. The fan blows air towards the plurality of shielding pieces and rotates the shielding pieces to define an air passage between each two adjacent shielding pieces. The air passage allows air to flow therethrough only when the fan is operating.
