Abstract (en)
[origin: CN105030154A] The invention relates to a suction nozzle for vacuum suction, in particular for tiled floor surfaces. The suction nozzle comprises a nozzle body (1) which comprises a suction mouth (2) and a suction channel (3) for releasing suction air stream on the underside of the nozzle body; the suction nozzle comprises sealing elements (4, 4 ' ), which are arranged in the working direction in front of and behind the suction mouth (2); and the suction nozzle comprises a suction chamber lateral restraint part (5) at the ends of the suction mouth (2), wherein the suction port (2), the sealing elements (4, 4 ') and the suction chamber lateral restraint part (5) delimit a suction chamber (6) on the underside of the nozzle body (1). The suction nozzle (2) has a measured width (B) between 200 mm and 280 mm transversely to the working direction. At least in the end-side suction port section (L) and the outside of a mouth region (7) of the suction channel (3), the measured height of the suction chamber (6) from the lower edge of the sealing elements (4, 4 ') to the inner surface of the suction mouth (2) is at least 1 mm and at most 20 mm, wherein the end-side suction port section extends from one end of the suction mouth (2) for a length of 60 mm. The distance (x) between a front sealing element (4) and the rear sealing member (4 ') is at least 15 mm and at most 50 mm. Furthermore, the bottom-side through-flow opening between the front sealing element (4) and a planar floor area and the bottom-side through-flow opening between the rear sealing element (4 ') and a planar floor area comprise total cross-section area which are less than 200 mm<2>, preferably less than 150 mm<2>.
