FIELD: mechanics. ^ SUBSTANCE: device for separation of flying substance (4) includes the tank (1) and two inspecting elements. The first controlling element (6) shows the controlling function defined by properties, at least, of one flying substance (4) and properties of materials of making parts of the first controlling element (6). Unlike it the second controlling element (7) executes inspecting function irrespective of properties, at least, one flying substance (4) and properties of materials of making parts of the first controlling element (6). The first controlling element (6) is located between the tank (1) and the second controlling element (7), it is penetrable for, at least, one flying substance (4). The second inspecting element (7) consists of an impenetrable material for flying substance and is characterised by presence of certain recesses (8). The first inspecting element (6) is located between the tank (1) and the second controlling element (7). Fragrant substances in particular, protection frames of plants refer to flying substances, ferromones and repellents which can be selected in a controllable condition. ^ EFFECT: device is simple for manufacturing and makes it possible to perform controllable selection of flying substance without a supply of mechanical or electric energy. ^ 17 cl, 3 dwg, 1 ex |
