发明名称 SPRING RETAINER FOR VACUUM CLEANER NOZZLE BRUSH
摘要 A nozzle (10) for a vacuum suction cleaner (14) has a suction inlet (24) on its bottom surface, and behind the inlet, the nozzle has a brush receiving chamber (30). The brush (50) comprises a support bar (52) in the brush chamber (20) and the support bar supports depending bristles (54). A respective combined spring and retainer (60) at both lateral ends of the brush chamber presses against the bristle support bar and urges the brush out of the housing (20). A retainer (70) which is integral with each spring (62) is clipped to each of two projections (40) at the lateral ends of the brush chamber and that retainer (70) is removable from its projection to facilitate removal of the brush from the brush chamber.
