<p>The device serves for evacuating a liquid substance in order to influence the ambient air. It is provided with a housing closed by two covers (2, 3) and having the configuration of a hollow cylinder (1). Mounted in this housing is the hollow roller (4) which can be rewound by a spring motor (5). An evaporation element (6) in the form of a towel, provided with a pulling strip (7) first leads, passing through the slit (1a) of the housing, inside the latter, and from there, passing through the slit (4c) into the hollow roller (4) where it envelops, in the manner of a pipe, a pad (8) filled with said substance. When the evaporation element (6) is pulled out the drive spring of the motor (5) is tensioned, then allowing automatic rewinding. The hollow roller (4), the evaporation element (6), the pulling strip (7) and the pad (8) constitute a replaceable assembly. For this purpose, a segmented region (1c) of the housing (1) is designed in the form of a cover which can be raised and is provided also with evaporation slits (1e), the width of which can be locked or adjusted by an adjusting closure device (9).</p> |
