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 (R 1 ), designed to heat up when an electric current is applied to it, and a refill ( 1 ) comprising a shell ( 4,
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 (R 1 ), 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 (R 1 ) 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.

1. A device for the diffusion of solutions, including:a heating device comprising a heater shell inside which there is an electric resistance designed to heat up when an electric current is applied to the resistance, anda refill comprising a refill shell containing the solution to be diffused and a wick soaked with the said solution and comprising at least one part in communication with the outside to diffuse the said solution, said refill being coupled to the said heating device so that the said resistance is operative to heat the said wick causing evaporation of the solution,the refill shell of said refill providing engagement means operative to engage with corresponding engagement means provided in the heater shell of said heating device, so that the said refill is selectably coupled to said heating device in position with respect to said heating device so that said refill is placed in the correct position for use and to prevent leakage of the solution said refill contains. 2. The device of claim 1, wherein said heater shell of the heating device comprises two half-shells fitted together by fixing means. 3. The device of claim 2, wherein said fixing means are clamps, heat sealing or ultrasonic welding. 4. The device of claim 1, wherein said engagement means provided on said refill includes at least one projection and said corresponding engagement means provided in said heating device is a circular channel designed to accept at least one said projection, or vice versa. 5. The device of claim 4, wherein said engagement means of the refill includes four projections arranged in a ring substantially similar to a circular or annular path defined by the circular channel of the heating device. 6. The device of claim 1, wherein said refill shell comprises a front half-shell and a rear half-shell on the outer surface of which the said engagement means of the shell is provided, and said heating device comprises a rear half-shell in which an electric plug is incorporated and connected to said resistance and a front half-shell in which said corresponding engagement means in the heater shell is provided. 7. The device of claim 4, wherein said refill shell comprises a front half-shell and a rear half-shell on the outer surface of which the said engagement means is provided, and said heating device comprises a rear half-shell in which an electric plug is incorporated and connected to said resistance and a front half-shell in which said corresponding engagement means in the heater shell is provided. 8. The device of claim 4, wherein said circular channel delimits a disc-shaped wall of said front half-shell of the heating device on the inside surface of which said resistance is positioned. 9. The device of claim 7, wherein said circular channel delimits a disc-shaped wall of said front half-shell of the heating device on the inside surface of which said resistance is positioned. 10. The device of claim 8, wherein said resistance has an axis positioned at an oblique angle of about 45° to the plane on which poles of a plug are placed. 11. The device of claim 6, wherein said front half-shell of the refill shell has a flat peripheral flange within which a recessed chamber to contain the solution and a recess to house the head part of said wick are defined, and said rear half-shell of the refill shell is in the shape of a flat plate and has substantially the same peripheral profile as said front half-shell of the refill shell so that the rear half-shell of the refill shell is attachable to the peripheral flange of said front half-shell of the refill shell. 12. The device of claim 11, wherein said wick comprises a stem part designed to be immerged in said solution inside said chamber and a head part wider than the stem part and designed to be at least partially in contact with the outside to permit evaporation of the solution. 13. The device of claim 12, wherein said recess to house the head part of said wick is substantially rectangular in shape and is provided with at least one opening to permit the head part of the wick to at least partially communicate with the outside. 14. The device of claim 13, wherein said opening in the front half-shell of the refill shell is closed by a strip which is removable by the user. 15. The device of claim 6, wherein said rear half-shell of said refill shell is made by moulding, so that said engagement means comprises projections solid enough to ensure that the projection fit firmly into a circular channel comprising said corresponding engagement means on the heating device.
