Embodiment Construction

[0039] figure 1 The suction cleaning device 2 according to the invention is shown by way of example, which is designed here, for example, as a hand-held guided floor cleaner. The suction cleaning device 2 has a base device 25 and a hose 21 connected to the base device. The hose 21 and the base device 25 are articulated via a connecting region 22 . The hose 21 leads into the suction line 16 which has a suction opening 23 through which suction material can be sucked into the suction cleaning device 2 . For example, an additional device (not shown here) having cleaning elements for acting on the surface to be cleaned can also be arranged on the suction opening 23 . A partial area is provided on the suction pipe 16 as a handle 19 by means of which the user can guide the suction cleaning device 2 during suction operation. During the suction operation, the user typically pulls the base device 25 behind him, the user typically alternately pushes and pulls the suction tube 16 away ...

Abstract

A filter (1) for a suction cleaning device (2), the filter (1) having a filter inner cavity (3) for receiving suction, for allowing air with suction to enter the filter The air inlet (4) of the inner chamber (3) and the filter material (5) for filtering the air leaving the filter inner chamber (3) through the filter material (5), the filter (1) has a surrounding filter The base housing (6) of the inner cavity (3), the base housing consists of a plurality of bending-resistant housing walls (7), at least one of which has a filter material (5), the plurality of shells The body walls (7) are pivotable relative to each other, so that the base shell (6) can be transformed from a folded initial posture to a deployed use posture without deformation of each casing wall (7). In order to improve the filter advantageously, it is proposed that the open housing side in the unfolded state of the filter (1) forms an air inlet (4), wherein the filter (1) has the air inlet (4) of the filter (1) A closed housing wall (7), by pivoting of which the air inlet (4) can be opened and closed.

Description

technical field [0001] The invention relates to a filter for a suction cleaning device, wherein the filter has a filter interior for receiving suction, an air inlet for allowing air with suction to enter the filter interior and a Air-filtering filter material through which the air leaves a filter cavity, which relates to a filter for a suction cleaning device, wherein the filter has a filter cavity for receiving suction, for use Air inlet with suction entering the filter cavity and filter material for filtering the air leaving the filter cavity passing through the filter material, wherein the filter has a base housing surrounding the filter cavity, The base housing consists of a plurality of bending-resistant housing walls, at least one of which has a filter material, wherein the housing walls are pivotable relative to one another so that no deformation occurs in each housing wall In the case of the case, the base shell can be converted from the folded initial posture to the ...
