Abstract: The device is based on an optionally single piece body (1), obtained by plastic moulding, 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

Abstract: An electric heating device releases active substances and has a housing (1) and cover (3) with holes (2) and (4) to receive a wick that is to be heated and soaked in a liquid that is to be evaporated. The housing (1) receives a pill-shaped PTC element (5) which is pressed between two electrodes (6) and (7) having a high heat conducting coefficient. The device has a small number of parts, and, with electrodes of suitable material and structure, provides a uniform heating of the round body which receives the wick.

Abstract: A housing within which a resistor is arranged is connected to two connections projecting through the bottom of the housing. The housing is further provided with an aluminum plate serving as a radiator which is held inside at the top of the housing, held by strips in the latter. The housing and the aluminum plate are provided with a hole through which a wick may pass to project through the mouth of a container holding liquid product to be vaporized by heating the wick through the resistor. A frame-like spacer element is arranged on the housing and fixed thereto, defining a supporting surface for a tablet, which tablet may be spaced to a greater or lesser extent by the spacer element in order for said tablet to be reached at all times by the appropriate heat to be full efficiently vaporized.

Abstract: The plug comprises a body (1) permanently coupled to the neck of a container for an air freshener or insect repellent liquid, with evaporation occurring through a wick (11) axially coupled in a concentric passage of the plug itself. An inner part of the axial passage of the plug in which wick (11) is inserted is provided with slits (7) along the main generatrix line, forming sectors (9) provided with semi pyramidal projections (12), defining means which allow motion in the direction of insertion of wick (11) and prevent its displacement in the outwards direction for removing said wick (11) from the plug, which prevents the container on which the plug is applied from being refilled with a product other than the original.

Abstract: A device is disclosed meant to perform evaporation of insecticides, perfumes or the like, wherein the degree of evaporation is controlled by a moving cap (9) which makes up the regulating element (6), which is meant to produce a chimney effect in the upwards motion of the generated vapor, so that this effect enhances evaporation, while regulation is achieved by the different heights at which moving cap (9) can be placed. This displacement is performed manually by moving guide (13) inside inclined track (10).

Abstract: The adjustment of the intensity of evaporation is conducted by means of the variation in the relative position between the upper end (6′) of the wick (6) which absorbs the product of the vessel (2) and the electroheating resistors (5) which favour the evaporation of said product, and more specifically keeping static said resistors and the assembly constituted by the vessel (2) and the wick (6) being displaceable. For this, said vessel (2) with any configuration, is provided with at least one revolution sector (7) in which a helicoidal groove (8) is established, of great pitch, operating as thread for the axial displacement of the container (2), when a rotational movement is applied to the same, at least one pair of opposed teeth (9) collaborating with said groove (8) which are finished off with leastically deformable arms (10) of the casing (1).

Abstract: It includes a housing (1) within which a resistor (3) is arranged connected to two connections (2) projecting through the bottom of the housing (1), further provided with an aluminum plate (5) serving as a radiator which is held inside at the top of the housing (1), held by strips (6) in the latter. The housing (1) and the aluminum plate (5) are provided with a hole (7) through which a wick may pass to project through the mouth of a container holding liquid product to be vaporized, by heating the wick through the resistor. A frame-like spacer element (8) is arranged on the housing (1) with fixing means to the housing (1), defining a supporting surface for a tablet (12), which tablet may be spaced to a greater or lesser extent by means of the spacer element (8) in order for said tablet (12) to be reached at all times by the appropriate heat to be full efficiently vaporized. The heating device may be used for both liquid and solid products.
