<p>The present invention refers to a method and a device to evaporate volatile substances such as aromatic substances and/or insecticides, in which these are evaporated using electrical heating means that heat a wick impregnated with the substance to be evaporated. The invention permits the evaporation of the substance efficiently by optimizing the use of heat energy generated by electrical heating devices. The invention comprises a rotating pipe with at least one opening with a portion of wick inserted in the said pipe and depending on the position of the said pipe relative to the heating means the amount of heat flow transmitted to the wick is regulated and, consequently, the degree of evaporation of the substance.</p> |
