  • an adjustable additional part is therefore attached to the underside of the mouthpiece, which can be adjusted according to the nature of the surface to be extracted.
  • at least the support surface of the vacuum cleaner nozzle can be changed so that the best possible cleaning result is achieved.
  • the suction channel itself remains unchanged, so that the cleaning result cannot be optimal.
  • the invention has for its object to design a vacuum cleaner mouthpiece of the type described in such a way that an optimal cleaning effect is always achieved with the most varied floor coverings.
  • the achievement of the object is achieved according to the invention in that several suction channels are provided on the mouthpiece part, specially adapted for suction on different floor coverings, which can optionally be coupled in terms of flow to the suction nozzle.
  • the geometry of the individual suction channels can be designed such that an optimal cleaning result is achieved with the correspondingly assigned floor covering. This is when the respective suction channel is used effective contact surface of the vacuum cleaner mouthpiece also adapted accordingly for achieving an optimal cleaning result.
  • Suctional activation of a suction channel specially designed for a specific floor covering is achieved in a simple manner in that the mouthpiece part is rotatably connected about a vertical axis to the upper housing part provided with the suction nozzle and can be blocked in a position corresponding to the working direction of the respective suction channel.
  • a suction pipe connected to the suction pipe By means of a suction pipe connected to the suction pipe, a pivoting movement can be exerted on the upper housing part until it locks in a position corresponding to the working direction of the desired suction channel with the mouthpiece part, so that this position is maintained when working with the vacuum cleaner mouthpiece.
  • the contact surface of the mouthpiece part can be adapted in a simple manner by providing support elements on the mouthpiece part, which are activated by the mutual pivoting of the mouthpiece part and upper housing part during the suction activation of at least one of the suction channels into one of the normal support level of the mouthpiece part protruding position can be brought.
  • the contact surface of the underside of the mouthpiece is simultaneously adapted to the type of flooring without an additional switching process.
  • Bristle strips are expediently provided as support elements on the underside of the mouthpiece. Instead of bristle strips, it is also possible to use rolling or sliding bodies which are adjustable in height relative to the underside of the mouthpiece.
  • a sufficient number of adjustment options is provided for most suction work in that three suction channels arranged in a triangular shape are provided on the mouthpiece part.
  • Such a vacuum cleaner mouthpiece can then be adjusted according to the three most common types of floor covering, namely hard and / or smooth floors, textile floor coverings with a loose and / or long pile, and coverings with a fixed and / or short pile, for optimal cleaning.
  • a bristle strip with respect to the working direction of the vacuum cleaner mouthpiece is arranged behind one of the suction channels running parallel to the latter, and a further bristle strip oriented perpendicular to the one bristle strip in the area of the triangular tip of the lower part of the mouthpiece opposite the suction channel in question is provided.
  • a relatively stable support of the vacuum cleaner mouthpiece is achieved by means of the bristle strips when vacuuming on smooth and hard floors.
  • the mouthpiece part is designed as a roller body which is provided with a plurality of suction channels and is rotatably arranged in the mouthpiece housing, the suction channels being able to be coupled in terms of flow to the connecting channel by correspondingly rotating the roller body.
  • FIG. 1 is a top view of the lower mouthpiece part of a vacuum cleaner mouthpiece
  • FIG. 2 a vacuum cleaner mouthpiece in a partial section along the line l-l
  • FIG. 3 a vacuum cleaner mouthpiece in top view, with an indication of the position of the suction nozzle in the three working directions,
  • FIG. 4 shows a side view of a vacuum cleaner mouthpiece which is provided with additional support rollers on its rear side
  • FIG. 5 shows a further embodiment variant of a vacuum cleaner mouthpiece.
  • a mouthpiece part of a vacuum cleaner mouthpiece 2 is designated.
  • the mouthpiece part 1 is triangular and rotatably arranged on a vertical journal 3 of an upper housing part 4.
  • a connecting channel 7 leads to the front of the vacuum cleaner mouthpiece 2 in the interior of the upper housing part 4.
  • a first, second and third suction channel 8, 9 and 10 are formed on the mouthpiece part 1.
  • the three suction channels 8-10 run essentially parallel to the three sides of the mouthpiece part 1.
  • the first suction channel 8 is specially designed for suction work on hard or smooth floors.
  • a bristle strip 11 is arranged behind the first suction channel 8.
  • Another bristle bar 12 is aligned perpendicular to the one bristle bar 11 and is attached in the region of the triangular tip 13 opposite the first suction channel 8.
  • the one bristle strip 11 is attached to the free end of a pivotably mounted lever arm 14.
  • the second suction channel 9 is specially designed for suctioning loose or long-fledged carpets. Its geometry is designed so that the best possible cleaning results are achieved with such a type of carpet. Attention is also paid to maintaining an adequate pushing force. Thread lifters 17 are also arranged on both longitudinal sides of the second suction channel 9.
  • the third suction channel 10 is finally designed for suctioning off solid or short-pile carpets.
  • a thread lifter 17 is also assigned to this suction channel 10 on one long side. There is also the possibility of installing this suction channel 10 thread lifter 17 on both longitudinal sides.
  • Suction channel 8 or 9 or 10 When one of the three suction channels 8 or 9 or 10 is activated by suction by correspondingly pivoting from the mouthpiece part 1 and the upper housing part 4, the relevant one becomes Suction channel 8 or 9 or 10 coupled via an inlet opening 18 of the connecting channel 7 to this and thus to the suction nozzle 5.
  • the corresponding suction channel 8 or 9 or 10 is activated in accordance with the particular nature of the floor surface to be extracted. In this way, optimal cleaning results are achieved even with different properties of the floor surfaces to be vacuumed, without having to accept high pushing forces.
  • supporting rollers 19 are also arranged on the rear of the elongated suction nozzle 5. These support rollers 19 take over a substantial part of the pressing force exerted on the vacuum cleaner nozzle 2 via the suction pipe 6. As a result, the effort required for the back and forth movement of the vacuum cleaner mouthpiece 2 during suction is reduced.
  • FIG. 3 shows the three setting options of the vacuum cleaner mouthpiece 2. I denote the working position for the first suction duct 8, II the working position for the second suction duct 9 and III the working position for the third suction duct 10.
  • the mouthpiece part 1 and the upper housing part 4 are pivoted, these two parts can be held in the respective position by latching, in which one of the three suction channels 8 or 9 or 10 is activated by suction. This makes it possible to work properly in the different positions of the vacuum cleaner mouthpiece 2.
  • a roller body 20 is rotatably arranged in the upper housing part 4 of the vacuum cleaner mouthpiece 2.
  • the roller body 20 has three suction channels 8-10.
  • the roller body 20 is advantageously hollow and provided with through openings 21 on its circumference in the areas lying between the suction channels 8-10.
  • the suction channels 8-10 are fluidly connected to the cavity 22 of the roller body 20.
  • the roller body 20 is inserted into a hollow channel-shaped receiving channel 23 provided in the upper housing part.
  • the receiving channel 23 On the underside of the vacuum cleaner mouthpiece 2, the receiving channel 23 has an interruption on its circumference, through which the respectively active fourth suction channel 8 or 9 or 10 emerges freely from the receiving channel 23 and can thus be guided over a floor surface to be cleaned.
  • the receiving channel 23 is provided with a connecting opening, so that a flow connection between the connecting channel 7 and the cavity 22 of the roller body 20 and thus with the respectively activated suction channel is made via the corresponding passage opening 21 of the roller body 20 8 or 9 or 10.
  • the remaining suction channels and the corresponding passage openings 21 are covered by the wall of the receiving channel 23 and are inactive in terms of flow.
  • a rotary handle can be provided on one or both sides of the vacuum cleaner mouthpiece 2.
  • the roller body 20 can be held in the respectively set position by means of corresponding latching.
