    Abstract: A V-spring member (18) for use in a driving system for a personal care appliance has regions (34, 36) at the ends of the spring which are large enough to support a contact with an end clamping assembly, the spring member including a cross-piece (40) extending between the longitudinal edges of the spring at the end regions, such that the ends of the spring member define a closed line. End clamping assemblies (16, 24) provided for such a V-spring member include a body portion (64) having a lower support portion (66) on which the V-spring is supported and a mating clamping member (88) positioned in registry with the support portion on top of the V-spring. The support portion and the clamping member include peripheral edges (74, 92) which have a curved cross-sectional configuration, and which are in registry, making contact with the spring member in the end regions in such a manner as to reduce stress concentrations in the end regions of the spring, thereby reducing fretting fatigue and fretting damage in the spring.

    Abstract translation: 用于个人护理用具的驱动系统中的V形弹簧构件（18）在弹簧的端部处具有足够大的尺寸以支撑与端部夹紧组件的接触的区域（34,36），弹簧构件包括 横截面（40），其在所述端部区域处在所述弹簧的纵向边缘之间延伸，使得所述弹簧构件的端部限定闭合线。 为这种V形弹簧构件提供的端部夹持组件（16,24）包括主体部分（64），其具有支撑V形弹簧的下部支撑部分（66）和位于注册表中的配合夹紧构件（88） 其支撑部分位于V形弹簧的顶部。 支撑部分和夹紧构件包括具有弯曲横截面构造的周边边缘（74,92），并且它们处于对准状态，以使得与端部区域中的弹簧构件接触以减小应力集中的应力集中 弹簧的端部区域，从而减少弹簧的微动疲劳和微动损坏。

    Abstract: The invention provides a wearable air purification device which actively generates a propelled stream of purified air for direct delivery to a region proximal to a user's mouth or nose for their immediate inhalation. An air chamber comprises a flexible diaphragm adapted to fluctuate between two extreme positions, thereby altering the volume within the chamber and alternately sucking and blowing air into and out of the chamber. Filtration elements are arranged in said air chamber. The filtration elements are arranged so as to make fluid communication with air displaced into the air chamber and, to make fluid communication with air displaced out of said chamber so that air is cleaned as it passes both into, and out of, the air chamber. The filtration elements actively remove particulate or gaseous pollutants. Embodiments of the invention may comprise a plurality of such air chamber assemblies, arranged so as to collectively deliver a continuous flow of air to a breathing zone of the user.
