In the suction nozzle a connectable with a vacuum cleaner suction tube receiving spigot is rotatably mounted and secured by locking in the axial direction. The connecting piece for the suction pipe is partially inserted into the suction. The arranged in the suction end portion of the connecting piece for the suction pipe forms an edge, which represents a flow obstacle with respect to the flow direction. Dirt can accumulate on this flow obstruction during operation of the vacuum cleaner, so that the effective flow cross-section is reduced, which adversely affects the suction power.
  • The WO 02/26097 shows a vacuum cleaner nozzle, in which the structure therefore is reversed, i. the suction nozzle is in sections in the connection piece introduced and rotatably mounted there. In such couplings, the connection is in usually realized by means of a copper ring, which is in grooves of Suction or connecting piece runs. In this structure, however, the assembly is very complex and leads to high costs.

  • The Saugrohranschlusseinheit invention builds on the generic state the technology in which the suction nozzle sections in the Saugrohranschlussstut zen introduced is. In this solution forms the arranged in the Saugrohranschlussstutzen end portion Although the suction nozzle also has an edge, this edge provides related to the flow direction no flow obstacle so that the risk of dirt accumulation and reduction of the effective cross section is eliminated. The invention exists therein, the connection between suction nozzle and suction pipe connection piece to design as a latching connection. To any flow obstacle To avoid this is the engaging hook on the inside the outer connection part, the suction pipe connecting piece so that it from the pipe of the suction nozzle, in its outer circumference an intervention for the hook is provided opposite the flow is covered. The air is flowing So along a completely plan pipe surface, which is not affected by any unevenness. The inventively provided Locking connection, in which the latching hook of Saugrohranschlussstutzens in the on the outer circumference the suction nozzle provided annular groove rotatably engaged meets two Functions at once. On the one hand, it connects the suction nozzle the suction pipe connecting piece, on the other hand it allows the rotation of the two nozzles against each other. So there are in addition to the locking coupling no further connecting parts such as copper rings or similar necessary to decouple attachment and rotation. This allows to form the Saugrohranschlusseinheit in two parts. In one In such case, the assembly of the Saugrohranschlusseinheit is particularly easy and inexpensive feasible.
  • Preferably are several over provided the circumference of the Saugrohranschlussstutzens distributed latching hook, which in the on the outer circumference of Saugstutzens provided annular groove rotatably engage. Only one latching hook can easily tilt in the annular groove by the one-sided load and is thus difficult to turn. At least two opposite ensure engaging latching hooks a simple common Slewing ring.
  • Especially It is advantageous if the latching hooks the entire end portion form the Saugrohranschlussstutzens. Especially if several over the Scope of Saugrohranschlussstutzens distributed latching hook provided are formed or a full circumference comprehensive locking edge is, a particularly good rotatable locking connection formed become. This locking edge is advantageously of cuts interrupted. This ensures a certain flexibility of the suction pipe connecting piece. So can the suction pipe connection easier to handle during assembly put the suction nozzle.
  • In this context, it is preferably further provided that the latching hook has a run-on slope. A run-on slope facilitates the radially outwardly directed movement of the latching hook when inserting the suction nozzle. If a plurality of latching hooks are provided, each of these latching hooks preferably has a corresponding starting bevel. Alternatively, the inserted end of the suction could be conical be formed.
  • According to one preferred development of Saugrohranschlusseinheit invention is provided that between the suction nozzle and the Saugrohranschlussstutzen a seal is provided. Such a seal prevents that in the connection region of the suction nozzle and the Saugrohranschlussstutzens Ambient air is sucked in, which deteriorate the efficiency of the vacuum cleaner would. The seal is preferably not provided as a separate element, but integral with the suction nozzle and / or the Saugrohranschlussstutzen formed to the assembly of Saugrohranschlusseinheit invention not to complicate.
  • In this relationship can be provided in an advantageous manner that the seal comprises a sealing lip which is integral with the suction nozzle or the Saugrohranschlussstutzen is formed. For example, the sealing lip can be molded onto the suction nozzle and be formed circumferentially.
  • Farther can be provided that the seal comprises a groove which in the suction nozzle or the Saugrohranschlussstutzen is formed. For example can the groove through a on the inner circumference of the Saugrohranschlussstutzens trained circumferential annular groove may be formed in the one at the suction provided sealing lip engages.
  • at preferred embodiments the Saugrohranschlusseinheit invention is provided that the suction in the suction pipe connection is rotatable. The arrangement is preferably chosen so that the suction nozzle and the suction pipe connecting piece through the locking connection (and optionally one or more stops) are axially secured, a Turning the suction nozzle in the suction pipe connection piece or However, a turning of the suction pipe connection to the suction nozzle possible is.
