Embodiment Construction

[0020] The nozzle shown in the picture can be attached to the vacuum cleaner via the suction tube and suction hose and is optimal for vacuuming on fabric surfaces and smooth floors. The basic structure of this suction nozzle consists of a suction head 1, a suction tube adapter 2, a sliding base 3, and a telescoping support and sealing element, wherein said suction tube adapter 2 is attached to the suction head in a movable manner about an axis of rotation Or a suction channel, which is rotatably connected to the suction head; the sliding base 3 has at least one lower side suction groove 4 defined by the edge of the suction port; the telescopic support and sealing The element for vacuuming smooth floors on the underside of the suction head comprises a front strip 5 which is breathable and / or has openings and is arranged upstream of the suction slot 4 in the suction direction. The front strip 5 is fixed to a vertically adjustable or rotatably arranged support 6 in the suction he...

Abstract

The invention relates to a vacuum cleaner nozzle, which includes: a suction head (1); a suction tube connecting piece (2), which is movably attached to the suction head or a suction channel around an axis of rotation, and the suction channel is rotatably connected to the suction head; a sliding bottom (3), which includes at least one lower suction groove (4) limited by the suction edge; and retractable bearing and sealing elements for sucking slippery floors, which include a front bearing strip (5) with or without air-permeable openings (15) arranged above the suction groove (4) along the dust suction direction. The front strip (5) is vertically adjustable or rotatably mounted on a supporting member (6) and fixed in the suction head (1), and the supporting member is actuated by means of aswitching element (7) available at the suction head. According to the invention, a separately selectable auxiliary device (10) is provided for sucking debris. Using the auxiliary device, a ground clearance of more than 2 mm is set between the floor surface to be cleaned and the already extended front strips (5) for sucking dust on smooth floor, while retaining the pivoting movement of the suctionhead (1), and the flow cross section of the opening (15) in the front strip (5) is changeable or not.

Description

technical field [0001] The invention relates to a nozzle for a vacuum cleaner, the nozzle having: [0002] suction head; [0003] a suction tube connector movably attached to a suction head or a suction channel rotatably connected to the suction head about an axis of rotation; [0004] a sliding base having at least one underside suction slot defined by the edge of the mouthpiece; and [0005] Telescoping support and sealing element for vacuuming smooth floors on the underside, comprising a front strip which is breathable and / or has openings and arranged in the suction direction upstream of the suction slot, [0006] Therein, the front strip is fixed to a vertically adjustable or rotatably arranged support in the suction head, which support can be actuated by a switching element operable on the suction head. The front strip can be formed, for example, from a bristle strip with a profiled lower edge. Background technique [0007] A suction nozzle having the above-mention...
