发明名称 Suction cleaner
摘要 A suction cleaner includes a suction unit for creating a flow of air and a flexible suction hose having a hose inlet at which air may be drawn into the suction hose. The suction hose leads from the suction unit and includes a first hose portion and a second hose portion having a connection to the first hose portion. The second hose portion includes the hose inlet. The suction unit includes a body that at least partially defines a storage volume in which the first hose portion can be accommodated when the first hose portion is in a contracted condition, and from which the first hose portion can be deployed when required. A first roller is positioned within the body and is supported on a first axis that is fixed with respect to the body. A second roller is positioned within the body and is supported on a second axis. The second axis is movable along an arc. A portion of the arc has a focus point positioned on the same side of the arc as the first axis. The first roller and the second roller cooperate to support the first hose portion in the contracted condition.
