Abstract:
1. Device for the evaporation of volatile substances that includes a wick which the substance travels up by capillarity, the wick being affected by heating elements that facilitate evaporation of the volatile substance, said device comprising a tubular pipe with open ends which contains an upper part of the wick, wherein a perimetric chamber is defined around the wick between said upper part of the wick and the pipe, in such a manner that a chimney effect can be created in said perimetric chambers wherein the pipe has at least one lateral opening that permits a flow of heat from the heating elements to the wick, wherein the heating elements are fixed and the pipe rotates in one plane and whereupon, upon rotational movement of the pipe a first extreme minimum evaporation position is defined in which the opening is not facing the heating elements and a second maximum evaporation position is also defined in which the opening faces these heating elements, said device further including a casing, wherein the heating elements and the pipe are supported by said casing and wherein an upper end of the pipe juts out of the top of the casing, forming an annular protuberance that facilitates manual movement of the pipe relative to the casing.
