Abstract: 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.

Abstract: It relates to an evaporator device of those which are used to diffuse fragrances, insecticides or other substances which are held in a recipient (1) in the form of two immiscible liquids. It comprises two wicks (2, 2?) which extend from the interior of the recipient (1) in contact with the liquid or the liquids to the exterior where the evaporation area thereof is located, and a stopper cover (3) which closes the recipient (1) and which is traversed by the wicks (2, 2?). One of the wicks (2) has an impermeable layer (4) which extends from its lower extremity to the stopper cover (3) of the recipient (1) preventing contact with one of the liquids and enabling the ingress of the other liquid into the wick (2) only through its lower extremity, thereby allowing the independent egress of each liquid through each wick (2, 2?).

Abstract: The invention relates to a diffuser of multiple volatile substances (air freshener liquid, odour absorption formulae, bactericide active substances, insecticides, etc.) comprising two or more containers (2, 2?) placed with a symmetrical or approximately symmetrical arrangement about a central body (1) to which they are joined by corresponding supports (3, 3?) that constitute said central body (1). Each container (2, 2?) holding the air freshener liquid or the desired formulation is closed by an active substance diffuser body (4) that also acts as a stopper and prevents dripping. When the device is at rest only one of the containers is diffusing. To change the fragrance, simply turn the device automatically or manually so that the container that was emanating is in the opposite position with respect to the other container, which will then diffuse its active substance, its evaporation being regulated individually or globally.

Abstract: Comprises a vessel (1) that houses the active liquid substance to be diffused, such as a fragrance, insecticide or other, through a breathable membrane (2) that closes the vessel (1) and comprises a porous part (3) placed near and parallel to the breathable membrane (2) in order to prevent the deformation of the membrane (2) when a vacuum is generated as the vessel (1) is emptied. The porous part (3) has a number of openings (4) through which passes the liquid to ensure its contact with the membrane (2) at all times for a homogenous evaporation and it occupies part of the volume of the vessel (1), absorbing the active substances, the non-volatile substances remaining in said porous part (3) after the vessel (1) has no more volatile components.

Abstract: Comprises a vessel (1) containing scented liquid, a wick (2) partially submerged in the liquid, a stopper (3) coupled on the mouth (7) of the vessel (1) and a cap (5) that covers the stopper (3) and has a lower tubular portion (11) provided with two windows (15) and an inner threaded segment that unscrews from a central threaded tubular portion (13) of the stopper (3) as the cap (5) is turned, raising it and gradually revealing the windows (15) so that the wick (2) is exposed to the exterior, facilitating the adjustable evaporation of the scented liquid, the cap (5) being provided with flexible stops (16) that are prolonged externally from the base of its lower tubular portion (11) and as they rise meet a trapezoidal inner peripheral flange (17) defined in a cylindrical body (14) of the stopper (3) to prevent the exit of the cap (5).

Abstract: The device comprises conventionally a plug (2) for the electrical supply of a heater element (14) to bring about the heating and evaporation, by way of a flat wick (10), of an active substance contained in a main receptacle (5). The novelty lies in the fact that said container (5) is heat-formed and defines a triangular configuration reservoir (6) with a flat extension (7) that accommodates the flat “Y”-shaped wick (10) in which the ends of its divergent arms (11) are engaged in recesses (9) in the mouth of the active substance reservoir (6), said wick (10) being pressed by an impermeable strip (12) which is heat-sealed to the body of the reservoir (6), so that the heater element (14) positioned facing the front end of the extension (7) brings about the warming of the wick (10) and the corresponding evaporation of the active substance, which will issue by way of a hole (16) in the impermeable strip (12) to be diffused in the environment.
