    • A generally flat air filtering device for an optical disk drive is disclosed. As air is sucked into the disk drive via an inlet of a filter, a filter mat included in the filter removes dust and other impurities from the air. The purified air comes out of the outlet of a tube and then enters and cools an optical disk unit. The filter mat has a generally V-shaped section and, therefore, has a filtering area great enough to enhance efficient dust collection as well as the service life of the filter. To isolate the purified air from surrounding dust-containing air, an endless projection or rail is provided on the tube to bite into the filter mat which is flexible.
    • 公开了一种用于光盘驱动器的大体平坦的空气过滤装置。 当空气通过过滤器的入口被吸入盘驱动器时,过滤器中包括的过滤垫从空气中除去灰尘和其它杂质。 净化的空气从管的出口排出,然后进入并冷却光盘单元。 过滤垫具有大致V形截面,因此具有足够大的过滤面积以增强高效的粉尘收集以及过滤器的使用寿命。 为了将净化的空气与周围的含灰尘的空气隔离,在管上设置有环形突起或轨道以咬入柔性的过滤垫。
