Suction tool for an electric vacuum cleaner
First Claim
1. A suction tool for an electric vacuum cleaner body comprising:
- 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 opening on the bottom face of the suction tool body, to the vacuum cleaner body;
a movable brush including a base having an undersurface with bristles embedded in the undersurface, the movable brush body provided in the middle of the suction inflow passage inside the suction tool body;
a driver device for driving the movable brush; and
a support shaft, located perpendicular to the direction of the suction air stream; and
a support plate including a cam slot, the support plate supported by the support shaft and integrated with the movable brush body, the support plate is driven by the driver device causing the movable brush body to sway and reciprocate back and forth about the support shaft.

Abstract
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.
