- the cover 102 of the pressure compensation chamber 100 is formed by the second wall 62 of the first part 52 of the holder 38, optionally in cooperation with the first wall 58.
- the opening or openings 104 are disposed at a portion of, for example, the first wall 58, which is outside the storage chamber 42, d. H. which protrudes beyond the first wall 72 of the second part 54 of the holder 38.
- the opening or the openings 104 is associated with a locking device 106, which prevents the ingress of suction material from the Einsaugraum 34 (which the opening 104 on a dirty side) into the pressure compensation chamber 100 (which is adjacent to the opening 104 on a clean side) is prevented.
- the blocking device 106 may, for example, be a filter device and / or comprise (at least) a movable closure element in the form of a backflow flap or a check valve which is open in a suction operation (when the suction chamber 34 is under negative pressure) , and is closed at balanced pressure difference and in particular at non-negative pressure.
- the closing element opens.
- the suction device 10 includes a separator 108 through which suction bags are separable from the tube 48.
- the suction device 10 comprises a closing device 110, through which hoses can be closed so that a suction bag 50 can be produced or a (filled) suction bag can be closed.
- the separating device 108 or the closing device 110 can be arranged fixedly on the suction device 10 or be assigned loosely. In a fixed arrangement, the separating device 108 and the closing device 110 are arranged in particular in the interior 20 of the suction material container 14.
- a (preferably single) suction bag 50 hangs on the holder 38 in the interior 20 of the suction container 14. This suction bag 50 is closed at the bottom by the closure 88 and is open to the continuous ring opening 78 to accommodate sucked suction.
- the sac bag 50 is made from the tube 48 which is positioned in the reservoir 44.
- a hose portion 86 of the corresponding length is pulled through the through-hole 84 and the bag is made through the closure 88.
- the closure 88 thus closes the hose down to the bottom 16 of the suction container 14, so that just no suction material can fall through and the suction bag 50 can absorb waste.
- the hose 48 is an endless hose, which in particular sits folded in the storage space 44.
- a corresponding hose wall is impermeable to air or formed by a filter medium impermeable to suction material.
- the suction bag 50 is impermeable to impermeability to suction with a corresponding closure 88.
- a pressure equalization takes place in the pressure equalization chamber 100 in that it is connected to the suction fan device 22 in a pressure-effective manner.
- sucking-in of the suction material bag 50 in particular in the case of an air-tight wall, is avoided by the suction fan device 22.
- the suction head 12 is removed from the suction material container 14 for removal of the suction material bag 50, for example completely (FIG. 9) or by unfolding.
- the holder 38 is fixed to the suction head 40. He is thereby mitabêt. With suction material acted upon areas are covered to the outside through the bag 50 and the holder 38.
- the suction material bag 50 By lifting the suction head 12 in a direction 112 away from the suction material container 14, for example, the suction material bag 50 can be enlarged by withdrawing further tube regions from the storage space 44 or, if necessary, an operator can pull on the suction material bag 50 in the opposite direction In the direction 112, draw tubing areas out of the reservoir 44 to extend the suction bag 50 in a direction along the direction 112.
- the suction bag 50 is still connected in this state via an air-tight wall with the hose 48 in the reservoir 44.
- the closure 88 through which the suction bag 50 is closed down, forms a first closure.
- the filled bag Suction bag 50 which was made of a tube, is characterized up-close and down-suction-tight and in particular hermetically sealed (with appropriate design of the second closure 114).
- the solution according to the invention also makes it possible to dispose of dusts which are hazardous to health (for example those in classes L, M or H according to the standard DIN EN 60335-2-69) in a comfortable and dust-free manner. The operator comes with the disposal not in contact with any health-hazardous waste.
- the suction bag 50 or 118 includes suction material acted upon components and the suction material 36 completely.
- the suction material is airtight about the suction bag 50 and 118 against an outside space outside of the corresponding Suction bag 50 and 118 included. Even with a sheuggut zucchini animation this inclusion is retained, as the bag for suction material 118 on the tube 48, on which previously the bag 50 has been made, is made again.
- the pressure compensation chamber 100 ensures that the suction function is not impaired.
- Suction-tight closing of suction bags on the first closure 88 and the second closure 114 can be achieved, for example, via a type of wire clamp pliers with clamping function, wherein, for example, a pair of scissors or the like can be integrated. It is thus also possible to integrate the separating device 108 into the closing device 110.
- FIGS. 2 to 8 A further embodiment of a suction device, which is shown in FIGS. 2 to 8 and designated 122, comprises a suction material container 14 ', on which a suction head 12' is detachably fixed.

- FIG. 12 shows a view in which a suction bag 50 is still arranged on the holder 38 '.
- the hose 48 in the storage space 44 comes to an end.
- a "last" suction bag 138 is made, which is attached to nem lower end as described above with a closure corresponding to the first closure 88 is closed.
- This suction bag 138 covers the suctions-leading portions of the suction device 122 from.
- the suction bag 138 is in particular manufactured and thereafter no further cleaning operation is carried out, so that the suction bag 138 is substantially empty. (However, it can be "contaminated” on its inside by the fluid-effective connection with suction material-carrying regions of the suction device 122.)
- the suction head 12 is placed with its upper side 140 on a base 142.
- the second part 54 'of the holder 38 is then released from the first part 52' (FIG. 13).
- the remaining suction bag 138 is not removed, but remains on the first part 52 'of the holder 38th
- a new tube 144 is inserted. This is thereby slipped over the "old" Suction bag 138 and slipped over in the area of the storage space 44 '.
- the new tube 144 is closed at its lower end 146 as described above to form a "new" sac bag 146.
- the suction head 12 ' is placed back on the suction material container 14'.
- the "old" sack bag 138 is now included in the new sack bag 146 (FIG. 14). He can now or at a later date (if a Cleaning operation is done and the new bag 146 is filled) are pulled in the new bag 146, ie be moved so that it no longer hangs on the holder 38. This makes it possible to insert a new suction hose, from which corresponding suction bag can be formed, without the operator coming into contact with suction material or areas of the suction device 122 that are loaded with suction material. Otherwise, the suction device 122 functions as described above.
