- FIG. 4 shows the rechargeable vacuum device 38 in a suction mode without a flexible collecting container 14, 16 being mounted on the dust separator unit 10, in particular the collecting funnel 30.
- the battery suction device 38 comprises a closure element 50.
- the closure element 50 is provided to close the outlet opening 52 of the collecting funnel 30 in a gas-tight manner. By closing the outlet opening 52 by means of the closure element 50, the collecting funnel 30 itself forms a (removable) rigid collecting container 82.
- the situation shown in FIG. 4 represents an emergency suction operation which can be used when no flexible collecting container 14, 16 is present.
- the intake protection unit 34 In order to enable the closure element 50 to be installed, the intake protection unit 34 must be dismantled in front of it. In the emergency suction mode, the suction protection unit 34 is unnecessary and does not exist.
- FIG. 6 shows a flow chart of a method with the battery-powered suction device 38.
- a full endless hose cartridge 22 is inserted into the collecting container magazine 18.
- a white direct method step 86 a piece of endless hose 20 is pulled down from the endless hose cartridge 22 in the collecting container magazine 18.
- the endless hose 20 is pulled out over the lower end 32 of the collecting funnel 30 and over the anti-suction unit 34.
- the open end of the endless hose 20 is sealed gas-tight by tying and / or tying.
- the endless The hose 20 is attached to the lower end 32 of the collecting funnel 30 by means of the mounting device 12.
- the endless tube 20 is placed in the circumferential direction of the collecting funnel 30 by means of the sealing unit 24 in a gastight manner against the collecting funnel 30.
- the connection of the knotted and / or tied part of the endless tube 20 to the collecting funnel 30 is sealed gas-tight relative to the surrounding atmosphere.
- another collecting container 16 for example a commercially available plastic bag 80, which is different from the endless hose 20, can be attached to the collecting funnel 30 by means of the assembly device 12 and sealed in a further process step 98 by means of the sealing unit 24 become.
- the suction mode is activated regardless of the previously selected alternative.
- the suction operation In the suction operation, a negative pressure is generated, which sucks the air out of the inner volume 70 of the collecting container 14, 16, whereby the collecting container 14, 16 contracts.
- the cyclone 28 In the suction mode, the cyclone 28 separates the coarse suction material from the gas flow.
- the suction operation is stopped, the collecting container 14, 16 unfolds and the separated suction material sinks down into the collecting container 14, 16.
- the collecting container 14, designed as an endless tube 20 is cut off and new knotted or twisted or tied above the suction material collected in the collecting container 14. This can be repeated until the entire endless tube 20 of the endless tube cartridge 22 is used up.
- a subsequent process step 106 the empty endless hose cartridge 22 is replaced by a full endless hose cartridge 22 and the process goes back to the aforementioned process step 86.
- the collecting container 16 which is designed as a commercially available plastic bag 80, is removed from the stow separator unit 10 and disposed of. If, after disposal of the collecting container 16 or after the collecting container 14 formed as an endless tube 20 has closed, no new collecting container 14, 16 is available, the closure element 50 can be mounted on the outlet opening 52 of the collecting funnel 30 in a method step 110.
- the intake protection unit 34 must first be dismantled in a procedural step 108.
- the rigid collecting container 82 is thereby formed. In at least one further procedural step 112, the rigid collecting container 82 is dismantled, emptied and reassembled.
