Definitions

  • the invention relates to a suction nozzle for a portable hard surface suction device for removing and sucking off a liquid from a hard surface, in particular from a window pane, with a housing which has a suction opening on a housing front side, which is connected to a suction channel which can be connected to a vacuum source. and with an elastically deformable pull-off lip, which is exchangeably held on the front side of the housing.
  • the invention relates to a portable hard surface suction device with such a suction nozzle.
  • a suction nozzle and a portable hard surface suction device for scraping and sucking a liquid from a hard surface are from the publication DE 20 2008 018 112 U1 known. They are used in particular to clean window panes, but also to clean other hard surfaces, such as shower cubicle walls, glass doors or tiled walls.
  • the suction nozzle has a housing with a housing end face on which a suction opening is arranged.
  • a suction channel connects to the suction opening, which can be connected to a negative pressure source of the portable hard surface suction device.
  • An elastically deformable pull-off lip is exchangeably held on the front side of the housing and protrudes forwards out of the front side of the housing in the direction away from the suction channel.
  • the portable hard surface suction device can be moved along the hard surface with the replaceable squeegee in the manner of a manual window squeegee, so that liquid can be drawn off the hard surface by means of the squeegee.
  • the liquid collects at the suction opening of the suction nozzle and a mixture of liquid and air can be sucked out of the suction opening.
  • the portable hard surface suction device has a suction unit that is flow-connected to the suction nozzle.
  • the separated liquid can be collected in a liquid tank of the portable hard surface suction device, which can be emptied if necessary.
  • the extracted air can be discharged from the suction unit to the surroundings of the hard surface suction device.
  • the suction nozzle can have an elastically deformable support lip, which is also arranged on the front side of the housing and is covered by the lip.
  • the squeegee lip is subject to a certain amount of wear, especially when removing liquid from tiled walls, and should therefore be replaced from time to time.
  • U1 known pull-off lip has a thickened area at its rear end that penetrates into the housing, which extends from a first side edge of the pull-off lip to a second side edge and which is received in a form-fitting manner by a receiving channel of the housing aligned parallel to the front side of the housing.
  • the pull-off lip can be pulled out of the side of the housing and a new pull-off lip can be pushed into the side of the housing, with the thickening dipping into the receiving channel.
  • this requires a high dimensional accuracy of the receiving channel and the thickening.
  • replacing the pull-off lip requires a certain level of skill on the part of the user and is often not readily apparent to the user.
  • a suction nozzle with the features of the preamble of claim 1 is from EP 3 195 780 A1 known.
  • the object of the present invention is therefore to further develop a suction nozzle of the type mentioned at the outset in such a way that the extractor lip can be replaced more easily without the extractor lip and the housing having to have very high dimensional accuracy.
  • the suction nozzle according to the invention has a fixing part for fixing the exchangeable pull-off lip on the front side of the housing.
  • the locking member is reciprocally movable relative to the housing between a pull-lip locking position (locking position) and a pull-lip releasing position (release position).
  • the replaceable pull-off lip can be fixed to the front of the housing with the help of the fixing part.
  • the user can move the fixing part into the fixing position.
  • the locking part In order to separate the peel-off lip from the housing, the user can move the locking part into a release position in which the locking part releases the peel-off lip. In the release position, the fixing part does not represent an obstacle for the pull-off lip, so that it can be easily separated from the housing.
  • Such a configuration makes it easier for the user to replace the pull-off lip, since he only has to move the fixing part from the fixed position into a release position in order to then remove the pull-off lip from the housing. The user can then position another pull-off lip on the housing and then transfer the fixing part back into its fixed position, so that the new pull-off lip is then fixed to the housing by means of the fixing part.
  • the fixing part is slidable along an outside of the housing of the suction nozzle.
  • the fixing part can be displaced relative to the housing.
  • the fixing part can be moved back and forth between the fixed position and the release position without tools. This makes it easier for the user to replace the pull-off lip, since no tools are required for this.
  • the user can move the retainer from the retainer position to a release position without tools, then replace the tear lip, and then move the retainer back to the retainer position without tools.
  • the housing preferably has a supporting edge on the front side of the housing, on which a rear end section of the pull-off lip can be positioned, and the fixing part has a holding strip which can be positioned on the rear end section of the pull-off lip.
  • This makes it possible to fix the pull-off lip to the housing in that its rear end section occupies a position between the supporting edge of the housing and the holding strip of the fixing part.
  • the support edge can form a bearing surface for the rear end section of the pull-off lip and thereby support the pull-off lip, and the holding strip can at least partially cover the rear end section of the pull-off lip.
  • the holding strip extends from a first side edge of the pull-off lip to a second side edge of the pull-off lip.
  • the rear end section of the pull-off lip can be completely covered by the retaining strip between the side edges of the pull-off lip. This enables the pull-off lip to be fixed to the housing with high mechanical loads.
  • the rear end section of the pull-off lip and the supporting edge of the housing have projections which are aligned at an angle to a longitudinal axis of the suction nozzle and which engage behind one another.
  • the projections that engage behind one another ensure that the pull-off lip cannot easily be pulled forwards, that is to say in the direction away from the suction channel, out of the housing.
  • the projections that engage behind one another are aligned at an angle to the longitudinal axis of the suction nozzle.
  • an alignment of the projections perpendicular to the longitudinal axis of the suction nozzle has proven to be advantageous.
  • the projections can extend perpendicularly to the longitudinal axis along the entire rear end portion of the peel-off lip and along the entire support edge of the housing.
  • the fixing part can advantageously be releasably connected to the housing.
  • the fixing part forms a force or form fit with the housing in the fixed position and can be moved into the release position if necessary.
  • 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 if necessary.

  • This end section can, for example, be configured so that it can be plugged into a base body of the portable hard surface suction device.
  • the end section of the suction channel can be inserted into an inlet channel of the base body to establish a flow connection between the suction nozzle and the suction unit of the hard surface suction device.
  • the locking connection between the fixing part and the housing takes place. If the user separates the suction nozzle from the main body of the hard surface suction device, then the end section of the suction nozzle protruding from the rear of the housing is his accessible to the suction channel and he can easily release the latching connection between the at least one first latching element, which is arranged on the rear side of the fixing part, and the at least one second latching element, which is arranged at the end section of the suction channel, in order to move the fixing part into a release position move in which the pull-off lip can be separated from the housing.
  • the fixing part can be separated from the housing. This allows the locking part to be completely separated from the body of the suction nozzle in order to replace the lip.
  • the fixing part can have a flat configuration.

  • the fixing part preferably has first holding elements which, in the fixing position of the fixing part, can be acted upon by second holding elements arranged stationarily on the housing with a holding force in the direction of the housing.
  • the first and second holding elements can together form a linear guide for moving the fixing part relative to the housing.
  • the first and second holding elements in such an embodiment of the invention have a guiding function in that they form a linear guide for the fixing part, so that the fixing part relative to the housing can be moved.
