Embodiment Construction

[0028] figure 1 A suction cleaning device 1 according to the invention is shown, which is designed here, for example, as a battery-operated vacuum cleaner. The suction cleaning device 1 has a housing 20 with a shaped handle 21 (see figure 2 ), for guiding the suction cleaning device 1 by the user. On the side of the suction cleaning device 1 facing away from the handle 21 , the housing 20 has a suction connection 10 to which an accessory, here eg a bottom suction nozzle 32 , is connected. The suction cleaning device 1 has a motor-fan unit, not shown in detail, which is used to suck the suction material into the suction cleaning device 1 . On the lever 21 there is a switch 22 for switching the motor-fan unit on and off, and a selector switch 23, by means of which the different power stages of the motor-fan unit can be selected. Furthermore, on the housing 20 of the suction cleaning device 1 there is a display device 24 which shows the state of charge of the battery of the s...

Abstract

The invention relates to a suction cleaning device (1) with a filter chamber (2) and a filter bag (4) with a holding plate (3), wherein the filter chamber (2) has a chamber cover (5), The chamber cover ( 5 ) has a locking device ( 6 ) with a spring element ( 7 ) on the inner side facing the filter chamber ( 2 ), wherein the locking device ( 6 ) is in contact with the filter bag ( 4 ). The retaining plate (3) is suitably arranged and designed such that the locking device (6) is only moved into the release position by the retaining plate (3) of the filter bag (4) against the restoring force of the spring element (7). Only the cavity cover (5) can move to the closed state of the filter cavity (2). In order to advantageously improve the suction cleaning device ( 1 ), it is proposed here that the locking device ( 6 ) is arranged on a lid edge region ( 8 ) of the chamber lid ( 5 ), which for closing The filter chamber (2) can engage the chamber edge region (9) of the filter chamber (2), wherein the locking device (6) is designed and arranged to be adapted to the chamber edge region (9) such that the locking device ( 6) In a preferred position corresponding to the relaxed state of the spring element (7), the cavity edge region (9) is hit and the lid edge region (8) is prevented from engaging with the cavity edge region (9).

Description

technical field [0001] The invention relates to a suction cleaning device with a filter chamber and a filter bag with a holding plate, wherein the filter chamber has a chamber cover which has a locking device with a spring element on the inner side facing the filter chamber, wherein , the locking device is adapted to the holding plate of the filter bag and is designed so that the cavity cover can only be moved when the holding plate of the filter bag moves the locking device to the release position against the restoring force of the spring element to the closed state of the filter chamber. Background technique [0002] Suction cleaning devices of the type described above are well known in the prior art. Such a suction cleaning device may be, for example, a hand-held vacuum cleaner or a self-propelled vacuum cleaner. The suction cleaning device can have an accumulator for power supply or alternatively can be supplied via the domestic power grid. In order to be able to inse...
