  • the elastomer component forms in the region of the passage slot 142 a U-shaped film hinge 143, which makes it possible to move the spring tongue 138 together with the latching projection 140 relative to the first housing half shell 76 forming hard component, but it is ensured that through the passage slot 142nd neither suction nor liquid can escape from the suction channel 80.
  • the elastomer component extends from the non-replaceable Abziehlippe 94 along the first side walls 86, 88 of the suction channel 80 to the latching hook 136. This is particularly clear from Figure 5.
  • the first housing half shell 78 in combination with the elastomer component, forms an injection molded part with a hard component and the elastomer component.
  • the hard component preferably consists of a polypropylene or ABS material and the elastomer component is preferably made of thermoplastic elastomer material.

Then the user can set the filling direction 56 from the dirty liquid tank 54 and empty the dirty liquid tank 54. The user can then insert the filling device 56 back into the dirty liquid tank 54 and insert it with the upper tank section 62 into the upper recess 64 and with the rear tank section 66 into the lower recess and engage with the base part 12.

Abstract

L'invention concerne une buse d'aspiration (32) pour un appareil portable de nettoyage de surface dures (10) destiné à retirer et aspirer des liquides depuis une surface dure, notamment une vitre, comprenant un boîtier de buse d'aspiration (77) présentant une première et une deuxième demi-coque de boîtier (76, 78) et une ouverture d'aspiration (82) sur laquelle est disposée au moins une lamelle de raclage (92, 94) flexible et à laquelle se joint un conduit d'aspiration (80) qui s'étend jusqu'à un segment terminal de conduit d'aspiration (30). Le segment terminal de conduit d'aspiration (30) peut être relié à une source de pression négative pour créer un écoulement d'aspiration, un élément d'encliquetage (136) étant disposé sur le segment terminal de conduit d'aspiration (30). Pour améliorer la buse d'aspiration (32) de telle manière qu'elle puisse être fabriquée de façon plus économique, la première demi-coque de boîtier (76) présente un segment de paroi à déformabilité élastique constituant l'élément d'encliquetage (136).
