  • the invention relates to a vacuum cleaner nozzle with a suction mouth, which is at least partially surrounded by a sealable on a surface to be cleaned seal.
  • Vacuum cleaner nozzles of the type mentioned are for placing on a substrate to be cleaned and for connecting, typically indirectly via a pipe, a hose and other facilities of the vacuum cleaner, formed with a suction fan of a vacuum cleaner.
  • a recess in the ground such as a crack, groove or joint
  • the suction mouth is surrounded by a seal, so that in the formed between the suction mouth and the ground, limited by the seal suction a high negative pressure can be generated .
  • the vacuum cleaner nozzle is passed over the recess in the ground, air flows at high speed through the recess in the suction chamber, whereby the depression is effectively cleaned.
  • such a seal has the disadvantage that when moving the vacuum cleaner nozzle in the sealed state on the ground coarse dirt is pushed in front of the seal and thereby a suction of coarse dirt is difficult or prevented.
  • a vertically movable limiting means is provided, which is designed as a sealing lip.
  • a sensor is provided for detecting a size property of the dust, depending on the sensor-detected size property, the limiting means is actively raised or lowered.
  • JPH 08206043 A discloses a vacuum cleaner nozzle having in its front region an inclined, connected via a flexible portion with the housing of the vacuum cleaner nozzle seal carrying projections resting on the ground. When advancing the nozzle, the seal is bent by the friction of the projections with the ground to the rear and thereby lifted off the ground. By forward and backward movement of the vacuum cleaner nozzle coarse and fine dirt can be absorbed.
  • the basic structure includes a suction head, which has a lower suction head plate with an open to the floor to be cleaned, channel-shaped suction mouth, supported on the ground support elements and a liftable and lowerable support plate.

As a result, the suction of coarse dirt is facilitated in spite of a sufficient sealing of the suction chamber when placed on the ground vacuum cleaner nozzle.
  • the outside support can be achieved that the sealing lip is bent by a force acting on its lower edge toward the outside force only in a part of its vertical extent, while the supported part only slightly or not at the bend participates; As a result, a relatively high flexural rigidity of the sealing lip is achieved in the relevant direction.

  • At least a first sealing lip is arranged such that when a feed movement of the vacuum cleaner nozzle by friction on the floor bending and especially when striking coarse dirt sufficient bending occurs to let this happen while at least one second sealing lip is downstream of the suction, the the coarse dirt, if this has not been absorbed by the suction mouth during the first run over, because of their in the feed direction higher stiffness pushes in front of him and thus prevents the exit from the suction chamber.
  • the lower rigidity of the at least one second sealing lip in the return direction permits the entry of coarse dirt into the suction space, while the higher rigidity of the at least one first sealing lip in the return direction results in coarse dirt within the suction space being carried along by it and thus within the suction chamber remains.
  • sealing lips with direction-dependent or direction-independent rigidity can also be provided laterally of the suction mouth.

Furthermore, it can thereby be made possible that even with a strong deflection of the sealing lip or wear of the sealing lip, the vacuum cleaner nozzle remains functional, especially in a resting of the at least one row of bristles only a small pushing force for moving the vacuum cleaner nozzle is needed.

  • Fig. 5 is the crossing of a recess formed as a groove 18 in the bottom 11 symbolically represented in the direction indicated by the arrow 13 forward direction. Since the suction chamber 12 is largely sealed even when receiving coarse dirt, in this a high negative pressure can be generated, which leads to a strong flow of air flow through the groove 18 when passing over the groove 18, which removes debris 19 therein. This is especially true if the suction chamber 12 is also sealed laterally. A partial seal is achieved by the wheels 6, which limit the suction chamber 12 laterally. An improved seal can be achieved by a respective, laterally arranged sealing lip, which is not shown in the figures and which can be connected to the sealing lips 9, 10 to a circumferential sealing lip. Depending on the direction of the groove 18 to be cleaned, a strong air flow, which allows effective removal of the dirt 19, is produced when passing over the sealing lip crossing the groove 18.
