摘要： A battery-powered washing unit is described which includes a motor drive unit driven by a DC battery pack with a yoke attached around the motor drive unit. An elongate and extendable handle is connected to the yoke for the user to grasp, and various brushes are connectable to the output shaft of the motor drive unit. Preferably the battery pack is sealed and self-contained and includes an integrated switch member at the top of the battery pack which consists of two powered positions, a low power and high power for various rotary speeds of the brush. Furthermore, the connection between the yoke and the motor drive unit consists of a locking mechanism having at least two locked positions, and a swivel position where the motor drive unit and the brush can swivel relative to the brush handle.

摘要： An air purifier, an air filter and a method of manufacturing an air filter for an air purifier are provided. The air purifier includes a base assembly, a filter assembly and a grill. A fan is mounted to the base assembly, and draws air through the filter assembly. The base and filter assemblies include adjoining walls having openings which are substantially smaller in area than the areas of the adjoining walls and area through which air is drawn in through the filter assembly. A resilient gasket having a passage approximately the size of these openings is positioned between the adjoining walls. The filter assembly is drawn towards the base assembly when the fan is operated, thereby enhancing the seal formed by the gasket against the adjoining walls. Unfiltered air is accordingly unlikely to bypass the filter assembly. The air filter is manufactured in an efficient manner through the use of a back plate having oblique end portions. A pleated HEPA filter is positioned in a U-shaped configuration and the ends thereof adhered to the oblique end portions. Top and bottom walls are then applied to the resulting structure.
摘要翻译：提供一种空气净化器，空气过滤器和制造空气净化器的空气过滤器的方法。空气净化器包括基座组件，过滤器组件和格栅。风扇安装在基座组件上，并通过过滤器组件吸入空气。基座和过滤器组件包括邻接的壁，其具有的开口面积小于相邻壁的面积，以及空气通过其穿过过滤器组件被吸入的区域。具有大致这些开口尺寸的通道的弹性垫圈位于相邻的壁之间。当风扇被操作时，过滤器组件被拉向基座组件，从而增强由垫圈抵靠邻接的壁形成的密封。因此，未过滤的空气不太可能绕过滤器组件。空气过滤器通过使用具有倾斜端部部分的背板以有效的方式制造。打褶的HEPA过滤器定位成U形构造，并且其端部粘附到倾斜端部。然后将顶壁和底壁施加到所得到的结构。
