  • the other Place of the vacuum cleaner nozzle is for determining the wet suction properties of the nozzle.
  • the scraper elements consist of flexible scrapers that on the underside of the vacuum cleaner nozzle on both sides of the suction mouth are attached.
  • the scrapers have a smooth Wiping edge and above the wiping edge in the longitudinal direction lined up openings.
  • the well-known vacuum cleaner nozzle is suitable for wet vacuuming smooth floors. Your dry suction properties are bad.
  • the invention has for its object a stripping element to specify for vacuum cleaner nozzles that both due to good dry suction properties as well as good wet suction properties distinguished on smooth floors.
  • the scraper is made of rubber or plastic and is flexible. It stands slightly on the bottom, e.g. approx. 1 mm, in front of the brush strip. Each according to the direction of movement of the vacuum cleaner nozzle Wipe edge in one direction or the other.
  • the Brush strip limits the deflection movement in one Direction and leads to a stiffening of the Scraper in this direction of movement. That allows the Training scraper very flexibly.
  • the openings of the Scraper and the notches associated with the openings the brush strip allow an effective entry of the Suction air, being taken up by the brush strip Particles detached in the air flow and with the suction air flow be dissipated. In addition, the openings are in in the immediate vicinity of the wiping edge so that stagnant moisture finds a passage.
  • Fluid retention on the floor to be cleaned are in a forward and / or backward movement of the suction head can be run over and can as soon as they are in the work area of the vacuum cleaner nozzle arrive, taken up in the suction air flow and discharged become.
  • One remaining on the floor to be cleaned Liquid film is captured by the wiping edge of the scraper and extracted in the suction air flow.
  • the invention teaches that the Scraper with a thickening on the top and one on it integrally formed flexible pull lip, the thickening on the brush bar and the pull-off lip which has the wiping edge and the openings contains, freely movable to the distance Brush strip is aligned.
  • the brush strip points expediently a head strip enclosing the bristles.
  • the arrangement is preferably such that the head-end thickening of the scraper on one leg this top bar is applied as well as the top of the Includes header.
  • the thickening of the scraper at the top as well as the head strip of the brush strip can e.g. by Adhesive bonded together.
  • the receiving groove can be arranged on a housing-fixed sole, it can but also be part of a raised and lowered arrangement.
  • the head Thickening of the scraper and the top of the Brush strip clamped in the receiving groove of a terminal strip are those who have the flexible pull-off lip on theirs outside of the brush strip facing away from the Has openings supporting legs.
  • the terminal block is for example, can be raised and lowered within the suction head the vacuum cleaner nozzle and can by means of a Actuating device can be retracted and extended.
  • the scraper is above of the openings has a web, which on the Brush strip facing away from the outside is molded on abuts a housing wall of the vacuum cleaner nozzle.
  • This footbridge fulfills additional sealing functions, supports the pull-off lip of the scraper and in this respect also has the function of a Stiffening.
  • the stripping element 1 shown in the figures consists from a brush strip 2 and a scraper 3 from one elastomeric material, e.g. made of rubber or a flexible Plastic.
  • the brush strip 2 and the scraper 3 are arranged immediately one behind the other and form a Functional unit, which in a receiving groove 4 on the in Fig. 1 only indicated underside of a vacuum cleaner nozzle is attachable.
  • a comparative examination of the Fig. 1 and 2 it can be seen that the scraper 3 is opposite the Brush strip 2 protruding smooth wiping edge 5 on the underside as well as in the longitudinal direction above the wiping edge 5 Has openings 6. In the area of these openings 6 Brush strip 2 with notches 7 (Fig. 3).
  • the Wiping edge 5 is about 0.5 to 2 mm at the bottom of the Brush strip 2 in front.
  • the scraper 3 is flexible and attaches depending on the direction of movement of the vacuum cleaner nozzle away from the brush strip 2 or towards the inside Brush strip 2 around.
  • the brush strip 2 limits the Deflection movement of the scraper 3 in one direction and prevents the scraper 3 under the suction of the Vacuum cleaner nozzle lifts off the floor.
  • the scraper 3 can therefore be made of very flexible material.
  • the scraper 3 in the embodiment and according to a preferred embodiment of the invention from a head-side thickening 8 and a molded thereon flexible pull-off lip 9, the head-side Thickening 8 abuts the brush strip 2 and the Pull lip 9 freely movable to the brush strip at a distance 2 is aligned.
  • the Brush strip 2 is a head strip 10 enclosing the bristles has and that the head-side thickening 8 of the scraper 3 abuts on one leg of the head strip 10 and on the other hand includes the top of the header 10.
  • the header 10 and the head-side thickening 8 of the Scraper 3 can be firmly connected, e.g. glued, his.
  • the exemplary embodiment consists of the receiving groove 4 Terminal strip 11, which has a flexible pull-off lip on it to the brush strip 2 facing away from the outside Has openings 6 supporting leg 11 '. That thigh 11 'limits the deflection movement of the pull-off lip 9 outside and contributes to the fact that the pull lip 9 with sufficient Pressure is on the floor to be cleaned, if the vacuum cleaner nozzle (to the right in Fig. 1) is moved.
