The invention relates to a device for evaporating an active fluid substance (12). Said device has a wick (7) which can be dipped into the active fluid substance (12) and is entended to deliver the active substance. When dipped one end of the wick protrudes from the active fluid susbtance and is provided with a heating device (3) provided on the wick in the region of the protruding end. Said device is characterised in that the form of the wick is such that the active fluid substance (12) cannot substantially pass through the outer surface of said wick at least along the length thereof dipping into the active fluid substance, the active fluid substance (12) can substantially pass through said wick in the region of its end surface (10) opposite the protruding end, and evaporating active substance (12) can pass through in the region of the heating device (3) at least when the wick is heated. The active fluid substance therefore rises uniformly into the wick.
L'invention concerne un dispositif permettant de vaporiser une substance liquide, comprenant une mèche (7) pouvant être plongée dans la substance liquide (12) et servant à faire remonter ladite substance, ladite mèche présentant, à l'état plongé, une extrémité qui sort de la substance liquide. Dans la zone de l'extrémité de la mèche sortant de la substance liquide, se trouve un dispositif de chauffage (3). Le dispositif présenté se caractérise par une mèche conçue de façon que son enveloppe soit sensiblement imperméable à la substance liquide (12), au moins sur sa partie plongée dans ladite substance, et qu'elle soit, dans la zone de sa face (10) opposée à son extrémité sortant de la substance liquide (12), sensiblement perméable, et, dans la zone du dispositif de chauffage (3), au moins lorsqu'elle est chauffée, perméable à la substance (12) vaporisée. Ainsi on obtient une remontée plus régulière de la substance liquide dans la mèche.
