Abstract: An air purification apparatus has an inner housing with an air inlet and an air outlet. The inner housing is fabricated of sheet metal material which can be contoured for mounting interior components, such as a blower and a HEPA filter, directly to the inner housing itself, without requiring extraneous mounting brackets, mounting flanges and the like. An outer housing is secured substantially about the inner housing with portions thereof spaced from the inner housing and having an air inlet and an air outlet communicating respectively with the air inlet and the air outlet of the inner housing. In the preferred embodiment, the outer housing is fabricated of molded plastic material, with integrally molded vertical reinforcing ribs, and a recessed integral ring about the outlet for storing an electrical cord. Closures are provided for the inlet and the outlet of the outer housing to seal the housing when the apparatus is not in use.

Abstract translation: 空气净化装置具有带有空气入口和空气出口的内部壳体。 内壳由钣金材料制成，其可以轮廓形成用于将诸如鼓风机和HEPA过滤器的内部部件直接安装到内部壳体本身，而不需要外部安装支架，安装法兰等。 外壳基本上围绕内壳固定，其中其部分与内壳间隔开，并具有与内壳的空气入口和空气出口分别连通的空气入口和空气出口。 在优选实施例中，外壳由模制塑料材料制成，具有整体模制的垂直加强肋，以及围绕出口的凹陷的一体环，用于存储电线。 为外壳的入口和出口提供闭合件，以在设备不使用时密封外壳。
