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