Definitions

  • the invention relates to a filter bag sleeve for a vacuum cleaner, a paper bag and an enveloping film bag being applied to connecting pieces that are aligned with the inside of a vacuum cleaner in connection with mutually aligned openings.
  • the filter bag sleeve according to the invention is so far attached to a two-part filter bag arrangement consisting of a film bag and a paper bag and is from the inside of the vacuum cleaner to the outside acting inlet, which merges into a nozzle in the interior of the vacuum cleaner postponed.
  • the object of the invention is therefore to develop a filter bag sleeve of the type mentioned in such a way that the filter bag is connected to the inlet fitting in a reliable manner and, in addition, contamination of the operator is excluded.
  • the invention is characterized by the technical teaching of claim 1.
  • a slide is integrated in the filter bag sleeve, which is designed as a film slide.
  • the slide is closed, ie it is moved laterally and also engages in its end position, so that the slide valve can no longer be opened automatically.
  • the filter bag sleeve as such is further designed so that it has an additional catch on the cylindrical part of the inlet fitting.
  • additional locking tongues are designed so that they snap into a groove in the inlet fitting.
  • the filter bag sleeve is thus snapped onto the inlet fitting, which has the advantage that a form-fitting and thus also mechanically safe and yet easily manually detachable connection is achieved, the function of the seal between the inlet fitting and the filter bag sleeve being additionally sealed into a groove on the inlet fitting nozzle , inserted sealing ring (O-ring). It is also essential that the film slide is guided in a sealed manner in the space between the flange part and the head part.
  • the sealing is preferably carried out via lip seals which are arranged opposite one another on the circumference of the recess in the flange and head part. These lip seals come into contact with the slide valve from both sides and seal it.
  • the film slide is operated manually by pulling it over the opening of the filter bag sleeve in the manner of a film seal.
  • Figure 1 shows the filter bag sleeve in section.
  • Figure 2 shows the flange part enlarged, partly in section.
  • Figure 3 shows the flange part in plan view.
  • Figure 4 shows the flange part in side view.
  • Figure 5 shows the headboard in plan view.
  • Figure 6 shows the head part, partly in section, in a side view.
  • Figure 7 shows the slide valve in plan view.
  • FIG 1 it can be seen that a head part 7 according to Figure 5 and Figure 6 is glued to the outside of the filter bag 6, which in turn can be covered on the outside by a slide 4 according to Figure 7.
  • This slide 4 is slidably guided along latching feet 18 on the head part 7, the guide on the other side being formed by a corresponding surface of a flange part 5.
  • the flange part 5 and the head part 7 are held together by snap connections.
  • the flange part 5 according to FIG. 1 forms an opening 14 through which the dirt is let into the filter bag 6.
  • the flange part 5 has a tubular extension, on the inside of which two detents 8 are arranged, distributed around the circumference, with which the flange part 5 is snapped onto an associated groove in the region of the inlet fitting, not shown.
  • an O-ring is also arranged in a manner known per se, which lies against the inside of the tubular flange part 5.
  • the flange part 5 On the outer circumference, the flange part 5 according to FIG. 2 has a groove 12 in which a plastic bag 10 is held. The mounting is done in that a clamping ring 13 engages in this groove and clamps the plastic bag 10.
  • the head part 7 according to FIGS. 5 to 6 consists of a pre-bent part, which should adapt to the shape of the flange part 5 as far as possible in order to ensure that the film slide 4 fits snugly against this leaf-shaped head part 7.
  • the pre-bend also makes the necessary dust tightness between the head part 7 and the slide 4 achieved, as well as an inhibiting effect that prevents the slide valve from being accidentally moved.
  • the pre-bending also results in a permanent prestress for the snap-in connection of flange part 5 and head part 7.
  • the head part defines an inner opening 17 which is substantially aligned with the opening 14 of the flange part 5.
  • latching feet 18 are formed on one side of the head part 7.
  • latching feet have hook-shaped lugs which engage in associated recesses 19 in the flange part 5 according to FIG. 3.
  • a dome 25 is attached, which cooperates with the grip hole 26 of the slide 4. So that in addition to the clamping effect by the pre-bending of the head part 7 accidental and unintentional closing of the slide 4 prevented and the slide 4 of Figure 5 is thus locked in the open position on the head part 7 of Figure 5.
  • the entire filter bag sleeve consisting of the head part 7, the flange part 5 and the film slide 4, consists of a plastic material that can be optimally glued to the paper material of the filter bag 6.
  • lip seals 9 (FIG. 1, 2) are present, which are arranged on the circumference of the recess in the head part 7 and the flange part 5 and which seal (frictionally) from both sides against the film slide 4.
