Abstract
A device (1) for the diffusion of solutions is made up of a heating device (50) comprising a shell, formed by two half-shells (51, 52), inside which there is an electric resistance (R1), designed to heat up when an electric current is applied to it, and a refill (1) comprising a shell (4, 5) containing the solution to be diffused and a wick (3) soaked in said solution and comprising at least one part that is in contact with the outside to diffuse the said solution. The refill (1) is coupled to the heating device (50) so that the resistance (R1) may heat the wick (3) causing the evaporation of the solution. The shell (5) of the refill (1) is provided with engaging devices (19) that will fit into the complementary engaging devices (55) provided in the shell (51) of the heating device (50), so that the refill (1) may be coupled with the heating device and may be turned on it so that it may be positioned in such a way as to prevent leakage of the solution it contains, whatever the direction in which the power socket on the wall is installed.
