发明名称 Spring retainer for vacuum cleaner nozzle brush
摘要 A nozzle for a vacuum suction cleaner has a suction inlet on its bottom surface, and behind the inlet, the nozzle has a brush receiving chamber. The brush comprises a support bar in the brush chamber and the support bar supports depending bristles. A respective spring at both lateral ends of the brush chamber presses against the bristle support bar and urges the brush out of the housing. A respective spring supporting retainer which is integral with each spring is clipped to each of two projections at the lateral ends of the brush chamber and that spring supporting retainer is removable from its projection to facilitate removal of the brush from the brush chamber.
