Definitions

  • the suction nozzle according to the invention has a fixing part for fixing the replaceable Abziehlippe on the housing front side.
  • the fixing member is movable relative to the housing between a position defining the Abziehlippe (fixed position) and the Abziehlippe releasing position (release position) back and forth.
  • the interchangeable Abziehlippe can be fixed by means of the fixing part on the housing front.
  • the user can move the fixing part in the fixed position.
  • the fixing part can move the fixing part in a release position in which the fixing part releases the Abziehlippe. In the release position, the fixing part is no obstacle to the Abziehlippe so that they are easily separated from the housing.
  • the support edge may form a bearing surface for the rear end portion of the Abziehlippe and thereby support the Abziehlippe, and the retaining strip may cover the rear end portion of the Abziehlippe at least partially.
  • the fixing part can be releasably connected to the housing without tools.
  • the user does not need a tool to connect the fixing part to the housing and to release the connection again when needed.
  • the fixing part is separable from the housing. This makes it possible to completely separate the fixing part from the housing of the suction nozzle to replace the Abziehlippe.
  • the fixing part may have a planar configuration.
  • the fixing part in the fixed position covers at least partially an outside of the housing.
  • the fixing part is arranged in the fixing position on an outer side of the housing, and the outer side is at least partially covered by the fixing part.
  • the fixing part on a cover plate, which covers an outside of the housing at least partially in the fixed position of the fixing part.
  • the housing has on an outer side a receptacle into which the fixing part can be inserted.
  • the fixing part is displaceable along an outer side of the housing of the suction nozzle.
  • the fixing part can be moved relative to the housing.
  • the fixing part is initially displaceable along an outer side of the housing and subsequently separable from the housing.
  • the fixing part can be acted upon in the fixed position of the housing with a holding force directed towards the housing.
  • the fixing part is acted upon in the fixed position with a force in the direction of the housing.
  • the Abziehlippe has in a particularly preferred embodiment of the invention in a direction away from the suction channel forward direction of the housing front side projecting longitudinal section, followed by a in the undeformed basic position of the Abziehlippe inclined to the longitudinal section free end portion.
  • the Abziehlippe example, an L-shaped profile with a first leg, which forms the longitudinal portion, and with a first leg to the first leg obliquely or vertically aligned second leg, the free end portion forms.
  • the free end portion may be formed significantly shorter than the longitudinal portion, so that the profile of the Abziehlippe is configured substantially hook-shaped.
  • the invention relates not only to a suction nozzle but also to a portable hard surface suction device with a suction nozzle, as has been explained in detail above.
  • the portable hard-surface suction device is preferably designed as a hand-held device which can be carried by the user with one hand and can be guided along a hard surface, in particular on a window pane, in the manner of a manual window puller.
  • a suction flow can be generated at the mammal opening of the suction nozzle, under the effect of which a mixture of liquid and air can be sucked into the suction channel.
  • the aspirated liquid can be separated from the mixture of liquid and air with the aid of the separating device and transferred into the liquid tank.
  • the aspirated air can be released through the air outlet openings of the portable hard surface suction device to the environment.

Abstract

L'invention concerne une buse d'aspiration (12) pour un appareil d'aspiration portable pour surfaces dures (10) destinée à retirer et aspirer un liquide sur une surface dure, en particulier une vitre de fenêtre, comprenant un logement (36) qui présente sur une face frontale dudit logement (44) une ouverture d'aspiration (46) à laquelle se raccorde un canal d'aspiration (48) qui peut être raccordé à une source de dépression, et comprenant une lèvre de retrait (58) déformable élastiquement qui est montée de manière à pouvoir être remplacée sur la face frontale de logement (44). Pour perfectionner la buse d'aspiration (12) de sorte que la lèvre de retrait (58) puisse être remplacée plus simplement sans que la lèvre de retrait (58) et le logement (36) ne présentent obligatoirement une très haute durabilité, la buse d'aspiration (12) selon l'invention comprend un élément de fixation (100) pouvant être déplacé en va-et-vient par rapport au logement (36) entre une position de fixation et une position de libération, la lèvre de retrait (58) pouvant être fixée au logement (36) en position de fixation de l'élément de fixation (100) à l'aide de l'élément de fixation (100) et séparée du logement (36) en position de libération de l'élément de fixation (100). L'invention concerne en outre un appareil d'aspiration portable pour surfaces dures (10) doté d'une telle buse d'aspiration (12).
