<p>A casing (1) and a lid (3) have orifices (2 and 4) to receive a wick to be heated and which is impregnated with a liquid to be evaporated. The casing (1) receives a pill-shaped PTC (5), which is held pressed between two electrodes (6 and 7) having a high heat conductivity coefficient. The invention is applicable to the fabrication of active substances evaporating devices which can be conveniently obtained with a reduced number of parts and with electrodes made of appropriate material and structure to provide a regular heating of the round body which receives the wick impregnated with the medium to be evaporated.</p> |
