<p>A heating device (1; 100; 200; 300; 400) for electrodiffuser (9; 409) comprises a housing shell (2, 4; 402, 404) including resistive means (R1, R2) which are heated when a current passes through them in order to heat, by heat exchange, said housing shell which is in contact with a porous element (83; 480) soaked with active ingredients, which are diffused when said porous element is heated. The resistive means comprise at least two resistances (R1, R2) connected in series by a connecting conductor element (7) having good characteristics of electricity and heat conduction to realise the electric connection of the resistive means (R1, R2) and, at the same time, to act also as a heating element. <IMAGE></p> |
