    Abstract: A fluid vaporizing device useful for vaporizing fluid into an aerosol includes a capillary tube made from an electrically conductive material, an upstream electrode connected to the tube, and a downstream electrode connected to the tube and provided with an electrical resistivity sufficient to cause heating of the downstream electrode during operation to approximately the same temperature as the tube at the point of connection. The upstream and downstream electrodes connected to the capillary tube divide the tube into an initial feed section, a heated section, and a tip. A source of material to be volatilized is provided to the tube at the feed section, passes downstream into the heated section, is vaporized, and then exits from the tube through the tip. The temperature profile of the tube along the heated section is controlled by varying parameters to substantially eliminate any effect of the downstream electrode as a heat sink.

  • Patent number: 6567613
    Abstract: An electrical device for evaporating a volatile liquid (for example an air freshener) into a room employs a wick (14) which extends upwardly from a container of the volatile liquid. A ring heater (16) is in the vicinity of the end of the wick and assists the evaporation. Vapor escapes from the device through an aperture (10) in a casing above the wick. The vapor emission rate is controlled by a user, who operates a control member in the casing, to alter the vertical position of a tubular body (18). Vapor may flow from the wick to the exterior through the tubular body (18) and then through the aperture (10). However, in all positions of the tubular body vapor may also flow to the aperture, and thence to the exterior, by an auxiliary route, not through the tubular body. It is found that the provision of this auxiliary route for vapor significantly improves the performance of the device.

  • Patent number: 6349168
    Abstract: A rotatable electric fumigation device includes an outer housing encasing a canister that contains a heat-activatable fumigant. A heating assembly, including electrical plugs fixedly attached to an electrical heater, extends partially into the housing to deliver heat to the canister and activate the fumigant. The housing is rotatable with respect to the electrical plugs and the heater to selectively position the orientation of the housing, thereby rendering the fumigation device operable regardless of the orientation of the electrical outlet.

  • Publication number: 20010053283
    Abstract: The present invention suitably provides a method and apparatus for controlling the temperature of a liquid vaporizer heating element, and thereby the rate of evaporation and level of fragrance delivery from the same. In accordance with one exemplary embodiment of the present invention, the device may include a switch that suitably allows the temperature of various types of heating elements to be controlled for different levels of fragrance output. For example, an exemplary embodiment may include a two-pronged plug adaptable to typical outlets that might be found in residential homes or businesses. In accordance with another exemplary embodiment of the present invention, the electrical switch generally provides varying resistance values to the electric circuitry of the vaporizer such that, by changing the switch setting, the operating temperature of the wick is controlled and thus the rate of fragrance evaporation from the vaporizer.

  • Patent number: 6309986
    Abstract: Disclosed herein are mats for dispensing volatile vapors such as insecticides. The mats are multi-layered. One layer is a carrier layer impregnated with the volatile. It is secured to at least one metal layer. The metal layer spreads the heat from a heater, thereby minimizing hot spots. In other embodiments additional layers are provided to provide a further heat distribution or temperature step down. An air gap can be provided between two of the layers.

  • Patent number: 6285830
    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).

  • Patent number: 6278840
    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).

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.

  • Patent number: 6250301
    Abstract: A vaporizer apparatus and method for uniformly extracting active ingredients of a specimen of crude natural product or inert particulate matrix impregnated with volatile substances, without pyrolysis, which uses hot air or a heated inert gas stream to volatilize the specimen. The heated air or gas is introduced from below (from either a hot air gun or a high pressure tank connected to a heat exchanger) and ascends through a permeable support structure (e.g., fritted glass disk, etc.), subsequently causing specimen particles disposed on the permeable support structure to be suspended within the confines of an isolation chamber. This allows a maximized gas extraction exposure for each suspended particle, and promotes a uniform extraction of the aggregate charge through its periodic mixing. A filter prevents the particles from being inhaled by the user. During device disuse, the heated airstream flows through an optional side-arm of the vaporizer apparatus, preventing wasteful loss of active ingredients.
