ABSTRACT:
The present invention relates to an electric evaporator device of volatile substances with adjustable evaporation intensity. A heating plate (4) defines a first chamber (6) separated from a second chamber (8), wherein a heat generator (5) is located inside the first chamber (6). A regulation opening (13), located in the first chamber (6), allows the exit of a heated air flow from the first chamber to regulate the temperature both in the first chamber (6) and the heating plate (4), enabling thus the regulation of the evaporation rate.
