SUCTION TOOL FOR AN ELECTRIC VACUUM CLEANER |
摘要 |
A suction tool for an electric vacuum cleaner includes: a suction tool body which is connected to the vacuum cleaner body and has a suction inflow passage therein for conducting a suction air stream from a suction port, to the vacuum cleaner body; and a movable brush which is provided inside the suction inflow passage formed in the suction tool body and is driven by a driver device. In this tool, the movable brush sways and reciprocates back and forth about a support shaft, perpendicular to the direction of the suction inflow stream. Alternatively, the tool may have a linear motor which operates so as to reciprocate a rod which is liked at one end of it with oscillatory plate pivoted inside the suction tool. Further, this movable brush may be formed of a unit which is composed of a sweeping member having a pair of front and rear sweeping parts and a moving brushing part embedded in between, wherein the front sweeping part is shorter than the rear sweeping part.
