摘要： A self-cleaning joint is disclosed. The joint (15) is disposed in an air flow passage (30), such as that of a vacuum cleaner power nozzle (10), and allows an element attached thereto, such as a vacuum cleaner hose to which it is connected, to be pivoted between first and second positions. The joint (15) includes a chamber (20) and a tubular member (22) having a first portion (23) pivotably disposed in the chamber and a second portion (24) protruding from the chamber (20). To prevent abrasion of the joint (15) caused by the accumulation of abrasive particles, the inner walls of the chamber are provided with grooves (34,35, 36) where any dust which penetrates the joint (15) can collect. The grooves (34, 35, 36) are positioned so that they are cleaned periodically by the flow of air in the passage (30).
摘要翻译： 公开了一种自清洁接头。 接头设置在诸如真空吸尘器动力喷嘴的空气流动通道中，并且允许附接到其上的元件（例如其连接的真空吸尘器软管）在第一和第二位置之间枢转。 接头包括腔室和管状构件，其具有可枢转地设置在腔室中的第一部分和从腔室突出的第二部分。 为了防止由磨料颗粒堆积引起的接头的磨损，腔室的内壁设置有凹槽，其中可以收集穿过接头的任何灰尘。 凹槽定位成使得它们通过通道中的空气流定期清洁。
