    • An air valve includes a frame and a sheet of thin material. The frame may have an outlet-side member configured mounted on a fan housing and an inlet-side member rotatably coupled to the outlet-side member. The material may have top and bottom edges, and a plurality of folds perpendicular to the top and bottom side edges that divide the sheet into a plurality of sections. The material may be attached to the outlet-side member and the inlet-side member, and configurable between folded and expanded positions. An attraction between a magnetic component on the inlet-side member and a magnetic component on a rotating fan blade may cause the inlet-side member to rotate, moving the material into the folded configuration. When the fan blade is not rotating, a spring attached at a pivot point may cause the inlet-side member to rotate in an opposite direction, moving the material into the expanded position.
    • 空气阀包括框架和薄材料片。 框架可以具有安装在风扇壳体上的出口侧构件和可旋转地联接到出口侧构件的入口侧构件。 材料可以具有顶部和底部边缘,以及垂直于顶部和底部侧边缘的多个折叠部,其将片材分成多个部分。 该材料可以附接到出口侧构件和入口侧构件,并且可在折叠位置和扩展位置之间配置。 入口侧构件上的磁性部件与旋转的风扇叶片上的磁性部件之间的吸引力可能导致入口侧部件旋转,将材料移动到折叠构型。 当风扇叶片不旋转时,附接在枢转点处的弹簧可以使入口侧构件沿相反方向旋转,从而将材料移动到展开位置。
