Abstract
An airflow shielding device is configured for being secured to fan and includes a first member, a second member, and a plurality of shielding pieces. The first member defines a first through opening. The second member defines a second through opening corresponding to the first through opening. The shielding pieces are rotatably secured between the first member and the second member and rotate between a closed position, where the shielding pieces cover the first through opening, and an open position, where the shielding pieces are located so that air can flow through the first and second through openings.
Claims6
An airflow shielding device configured for being secured to a fan, the airflow shielding device comprising:
- a first member defining a first through opening;
- a second member defining a second through opening corresponding to the first through opening;
- and
- a plurality of shielding pieces rotatably secured between the first member and the second member, the plurality of shielding pieces can rotate between a closed position, where the plurality of shielding pieces cover the first through opening, and an open position, where the plurality of shielding pieces are located so that air can flow through the first and second through openings;
- the first member defines a plurality of gaps;
- a shaft is disposed on each shielding piece;
- and the shafts are rotatably received in the plurality of gaps;
- the first member defines a plurality of grooves respectively adjacent to the plurality of gaps;
- each shielding piece comprises a blocking portion;
- and the blocking portions are rotated in the plurality of grooves when the plurality of shielding pieces are rotated between the open and closed positions;
- and
- a positioning block is located in each groove;
- and the blocking portions of the plurality of shielding pieces abut the positioning blocks when the plurality of shielding pieces are in the open position.
A computer system comprising:
- a fan;
- a first member defining a first through opening;
- a second member attached to the fan and engaging with the first member, the second member defining a second through opening corresponding to the first through opening;
- and
- a plurality of shielding pieces rotatably secured between the first member and the second member, the plurality of shielding pieces can be rotated between a closed position, where airflow is blocked by the plurality of shielding pieces from passing through the first and second through opening, and an open position, where airflow is directed from the fan to pass through the first and second through openings;
- the first member defines a plurality of gaps;
- a shaft is disposed on each shielding piece;
- and the shafts are rotatably received in the plurality of gaps;
- the first member defines a plurality of grooves respectively adjacent to the plurality of gaps;
- each shielding piece comprises a blocking portion;
- and the blocking portions are rotated in the plurality of grooves when the plurality of shielding pieces are rotated;
- and
- a positioning block is located in each groove;
- and the blocking portions of the plurality of shielding pieces abut the positioning blocks when the plurality of shielding pieces are in the open position.
