1. A device for evaporating volatile substances comprising:
a heater which heats a wick impregnated in said volatile substances, wherein said heater is formed from a printed circuit board provided with at least one resistor;
the wick is flat, the wick has opposite sides with both sides of the wick exposed to allow evaporation of the volatile substances into air by capillary action, the wick has a heat emission area that is optimized by a flat shape of an impregnated surface of the wick that allows evaporation of volatile substances to the air;
the at least one resistor is arranged on a face of the printed circuit board that is oriented toward the exposed heat emission area of the flat shape of the impregnated surface of the wick;
the wick is mounted in U-shaped sections of a support; and
said printed circuit board comprises grooves for the passage of stops, in an assembled position the stops are in placement in the grooves of the printed circuit board and in contact with the U-shaped sections of the support.
