Abstract: Incorporates a device for active substances (3) which has a wick (6) and a first heating resistor (8) for operating the diffuser on normal system. It also has a single button (12) connected through an electronic circuit (10) to an additional second heating resistor (9) located in the same channel and after the first heating resistor (8) in the vicinity of the wick (6). Activation of the button (12) determines the switching on of the second heating resistor (9) and can also activate at the same time a fan (4) or even based on a fan speed (4) increase the same, moving from normal operating mode to boost mode in which a substantial and instant increase in evaporation and diffusion of the active substances is produced.

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.
