发明名称 Manually guided suction device or blower
摘要 A manually guided suction device or blower is provided that has a housing in which is formed a spiral blower path in which is disposed an impeller that is rotatably driven by a drive motor. The spiral blower path has an air-conveying air inlet and an air-withdrawing outlet. A connector is provided for the detachable connection of an air-conveying connection conduit, whereby when the connection conduit is mounted it overlaps with the connector, which is secured to the housing, over a prescribed axial length. To achieve a mechanically secure connection, an annular sealing element is held in a groove in a surface of the connector or connection conduit in the overlap region, wherein over the entire circumference thereof, the sealing element projects beyond such surface.
