Abstract:
1. Device for evaporation of active substances comprising: a casing having at least one slot for the diffusion of the active substance to the outside, a container for containing an active substance, said container being provided with a wick having a lower portion inside the bottle and an upper portion protruding from the bottle, electric plugs for the connection of the device to the electric mains, a first heating resistor arranged inside said casing in the vicinity of said upper portion of the wick and connected to the electric plugs, a fan arranged in said casing for providing an airflow through the upper portion of the wick, a second heating resistor arranged inside said casing in the vicinity of said upper portion of the wick, an electric push button to electrically supply said second heating resistor and at the same time act on the speed of said fan, and wherein the electric push button is operable to alternatively change the operation of the device between a normal operation mode and a boost operation mode, wherein in said normal operation mode said first heating resistor is activated and the fan is in a first condition, and wherein in said boost operation mode, the second heating resistor is selectively activated in addition to said first heating resistor and the speed of the fan is increased so as to increase the evaporation and diffusion of the active substance.
