Abstract: The system is based on a change in the intensity of evaporation caused by a chimney effect, modifying the flow of air that circulates through the environment apparatus in the surrounding area of the wick. It consists of using a casing (1) with slots (6) for the passage of air in its upper part. This is done in such a manner that said casing (1) can be used in isolation, thus attaining an apparatus that does not regulate the evaporation intensity, but that has a complementary part (7) joined to the upper part of said casing (1). This assembly, enabling free turning, has complementary slots (9), that determine a greater or lesser flow of air and the consequent regulation of the intensity of the evaporation, depending on the greater or lesser degree of opposition they have to the slots (6).

Abstract: The device comprises a base (1) and an exchangeable case (7), between which are placed corresponding components such as a bottle (9) containing the fragrant liquid and the corresponding wick (8), as well as the heating elements (4) connected to corresponding metallic contacts (5) and mounted on a support (3), also including a platform or printed circuit (2) with electronic components that allow optimizing the diffusion of the fragrance, to prevent olfactory saturation of the user, independently of the manual actuation means that allow regulating the intensity of evaporation of the fragrant liquid itself. The device also includes the corresponding plug (10) placed in correspondence with the part near the bottom end of the base (1).

Abstract: A heater device includes an external casing (1), an inner part (2), a pair of contact elements (3) and (3?), and a jack plug (4). Contact elements (3) and (3?) define pairs of salient projections (17) and (18) which allow connection of the jack plug (4) in two positions of rotation, at 90° to each other, and prevent connection in an intermediate position. The heater device operates to heat a wick which emerges from a vessel containing an active substance to cause the evaporation of the substance. The vessel is retained on the lower end of the heather device by a ring (26) provided on inner part (2).

Abstract: The invention provides a method for disinfection or the inhibition of microbial growth in the air, freshening and perfuming of the air, being based on the emission of particles into the air of a disinfecting composition based on essential oils and/or their active ingredients their mixtures with glycols and/or glycol ethers in variety of proportions. In accordance with the method of the invention, the particles emitted into the air which it is sought to disinfect, freshen and perfume, are produced using the evaporation of the liquid composition, through a wick indirectly heated to a temperature of less than 100° C. in its upper area.

Abstract: The device comprises four components, namely an external casing (1), an inner part (2), a pair of contact elements (3) and (3′), and a jack plug (4), with casing (1) and inner part (2) being provided with complementary means of retention, and inner part (2) being provided with means for mounting and securing contact elements (3) and (3′), in which are defined pairs of salient projections (17) and (18) which allow connection of jack plug (4) in two positions of rotation, at 90° to each other, and prevent connection in an intermediate position as the inner ends of the pins of jack plug (4) are left opposite a segment (19) recessed with respect to contact elements (3) and (3′).

Abstract: The device is based on an optionally single piece body (1), obtained by plastic molding, of cylindrical configuration, with the opening and the corresponding axial and central neck (3) for the passing of a wick that, at its lower end, is immersed in an active substance contained in a vessel to which the device is applicable, having optional ribs (4) for holding and positioning the wick heating resistances, as well as projections (6) with cross channels (7) for the positioning of the ends of the electrical resistances wires, being supplemented with a piece (8) acting as a clip, that by means of a flap or arm (9) formed in it, the ends of the resistances are kept in the flutings (7), and allows the positioning of the contactors through which the electrical supply to those heating resistances is set up, a positioning that is carried out on an upper slot (10) set up in that piece (8) which has contactor connection flaps (11), and optionally a cover that assures a more reliable fastening by pressing on the upper e
