The device comprises a container (1) of active substance in liquid form, which is sealed by means of a permeable membrane (3) which lets the active substance vapour pass and prevents the passage of liquid, being completed with a porous support ( 5) on the inner face of the membrane (3), so as to take the active substance to the centre of the membrane (3), this being warmed by a heater element (9) with pins (10) which are coupled directly onto the pins (8) of a socket plug (7), via which the device is powered, so that the evaporation of the active substance takes place by warming and it issues to the exterior by ways of slots (12) provided in a housing (11) which joins the container (1) to the socket plug (7). The assembly forms a disposable device, although the container (1) can be embodied so that it is interchangeable.

The invention claimed is: 1. Electrical device for releasing active substances, which includes a container (1) for an active substance in a liquid state, a heater (9) for evaporating this active substance and a socket plug (7) for power supply to the heater, characterised in that the container (1)

The invention claimed is: 1. Electrical device for releasing active substances, which includes a container (1) for an active substance in a liquid state, a heater (9) for evaporating this active substance and a socket plug (7) for power supply to the heater, characterised in that the container (1) includes a permeable membrane (3) which seals an open base of said container, said membrane (3) being composed of a polymeric material which allows vapour of the active substance to pass through the membrane but prevents the active substance in liquid state from passing through the membrane, the inner face of said membrane (3) being provided with a plain porous support (5) defining a wick by way of which the active substance is taken to the centre of the membrane (3), whilst, externally to the membrane, in correspondence with an intermediate area of the membrane and adjacent to said membrane, lies the heater element (9). 2. Electrical device, as defined in claim 1, characterised in that attached to the outer face of the permeable membrane (3) an impermeable film (6) is provided, sealed on the actual container (1) together with the membrane (3), said impermeable film (6) defining a barrier that prevents the evaporation of the active substance while the container is in storage, said impermeable film ( 6) being removable before the device is first put into service. 3. Electrical device, as defined in claim 1, characterised in that it comprises an intermediate housing (11) between the container (1) and the assembly formed by the heater (9) and the socket outlet plug (7), said housing (11) being provided with slots (12) for the active substance vapour produced by warming to issue to the external atmosphere. 4. Electrical device, as defined in claim 1, characterised in that the plain porous support (5) has the form of a disc or cross, being embodied in paper of high porosity, hardness and strength or of polymer or any other porous material, whose configuration enables the liquid or active substance to be taken from the container (1) to the centre of the permeable membrane (3). 5. Electrical device, as defined in claim 1, characterised in that the heater element (9) is linked directly to the pins ( 8) of the socket outlet plug (7), forming a single unit with said socket outlet plug. 6. Electrical device, as defined in claim 1, characterized in that it is a disposable device. 7. Electrical device, as defined in claim 1, characterized in that it is designed to be re-used by means of replacing the container. 8. Container to be used in an electric diffuser device, whether disposable or not, said container being arranged for housing an active substance to be evaporated, the container (1) including a permeable membrane (3) that closes an open base of the container, said membrane (3) being composed of a polymeric material selected to let vapour of the active substance vapour pass through the membrane (3) and to prevent passage of the active substance in liquid state; the inner face of said membrane (3) being provided with a plain porous support (5) defining a wick by way of which the active substance is taken to the centre of the membrane (3); characterised in that the container is provided with means (2) for attaching the container to the electrical diffuser device for heating the active substance in the plain porous support. 9. Container according to claim 8, characterised in that the outer face of the permeable membrane (3) is provided with an impermeable film (6), sealed on the container (1) together with the membrane (3), said film (6) defining a barrier that prevents the evaporation of the active substance while the container is in storage, said impermeable film (6) being removable prior to initial use of the device. 10. Container according to claim 8, characterised in that the means (2) for attaching the container to the electrical diffuser device comprise a perimetric wing (2). 11. Container according to claim 8, characterised in that the means (2) for attaching the container to the electrical diffuser device are configured so as to arrange the container with the centre of the membrane (3) adjacent to a heater element of the electrical diffuser device. 12. A container assembly for an electric diffuser, the container assembly comprising: a container for an active substance to be evaporated, the container comprising an open base; a permeable membrane that closes the base of the membrane comprising a polymeric material, the membrane for passing the active substance in a vapor state and for retaining the active substance in a liquid state a plain porous support provided proximate to an inner face of the membrane and wicking the active substance to the membrane.
