| 摘要 |
The invention relates to a combined nozzle for a dust vacuum cleaner, comprising a brush (10) or similar with an interchangeable arrangement at the end of a tube (2) connected to a suction device, with a lower planar face (11) and with joint means for an arrangement in two different transverse positions with relation to the tube (2) or longitudinally in the tube extension (2), where, in each position, the suction is achieved by an opening (12) in the planar face (11), or an opening (13) at one of the ends. The joint means comprises means for a pivoting (P, R) about at least two axes such that when in a position for suction by an end, the brush (10) is oriented such that said lower face (11) and the longitudinal axis of the brush are essentially parallel to the axis of the suction tube (2). |
