Combination brushroll and nozzle inlet control mechanism |
摘要 |
A vacuum cleaner including a nozzle base comprising a primary suction opening and a suction source. A dust cup assembly is releasably secured to the nozzle base. The dust cup assembly comprises a first inlet and a door positioned adjacent the inlet to selectively open and close the inlet. A rotatable brushroll assembly is positioned adjacent the primary suction opening. A three position control assembly is located on the nozzle base. The control assembly comprises a selector switch and a slide bar. Movement of the selector switch to first and second positions moves the slide bar out of engagement with a finger extending from the door allowing the door to open due to suction air. Movement of the selector switch to a third position moves the slide bar into engagement with the finger to prevent the door from opening due to suction air. The control assembly further comprises a guide arm assembly with a pair of walls forming an opening which selectively receives a first pulley belt, which moves the first pulley belt between alignment with the full-size pulley and an idler pulley. A second pulley belt engages a reduction pulley and a shaft of the brushroll.
