  • the device generally comprises a heating element 14 carried by and embodied in the base 11. h the embodiment shown in FIGs. 1 and la, the base is configured to include a base housing 12 such that the heating element 14 is disposed within the base housing 12.
  • the heating element is disposed adjacent an upper portion 12a of the base housing, or rests on an upper surface of a base, rather than lower in the housing as in the illustrated embodiment.
  • the heating element is configured to heat an aromatic substance. Since the idea is to increase the aroma given off by the aromatic substance by heating it to increase a vapor pressure or otherwise enhance evaporation and other mechanisms of transfer of the aromatic substance to the air, the heating element of the device can be configured in a wide variety of configurations, depending on the aromatic substance(s) to be heated. For example, a popular aromatic substance currently in the marketplace is scented wax, sold as a scented wax candle.
  • these candles include a glass container, which is filled with the scented wax and include a wick for burning.
  • the present device can be configured in such a way as to receive a scented candle and to heat it without burning the wick.
  • the heating element can comprise a substantially flat upper surface 15 on which the scented candle can be rested.
  • the device 10 can be configured such that the heating element 14 is configured to receive a scented liquid, hi this embodiment, the heating element itself can be configured in such a way that a bowl-shaped receiving area 17 is formed.
  • An advantage of this embodiment is that it allows the user to use an aromatic substance that is not in a separate container, if desired. For example, if the user preferred scented oil as the favored aromatic substance, the user could simply pour the oil directly into the heating element receiving area. As the oil dissipates into the atmosphere, the user would simply refill the receiving area to replenish the desired aromatic substance. Additionally, in this embodiment, the user can place one or more conventional scented wax candles that are not confined in a container, such as traditional candles made for use with traditional candle holders, within the bowl shaped receiving area to heat them.
  • This embodiment likewise allows the user to place within the bowl shaped receiving area any scented substance that releases fragr-ance at moderately elevated temperature; such as palletized wax, fragrance gel beads, and other such substances.

  • the side wall can be comprised of a material that inhibits thermal conduction.
  • a conductive side wall is desired then the side wall can either be comprised of a thermally conductive material or simply be an integrally connected or unitary part of the heating element.

  • the invention herein contemplates all known heating element configurations even though the primary embodiment shown in the drawings and in the description herein will be to a heating element having a generally circular shape.
  • the heating element is a PTC (Positive Temperature Coefficient) heating element.
  • PTC heating elements generally have a unique resistance to temperature which results in the resistance of the PTC decreasing as heat is drawn from the PTC.
  • PTC heating elements generally have an extreme positive temperature coefficient over a very narrow range of temperatures. PTCs can thus be self-regulated at a preset temperature and can vary wattage automatically in order to maintain the preset temperature.
  • the use of a PTC heating element in the present invention provides a heating device that accurately and efficiently controls temperatures and minimizes energy consumption.
  • the heating element is similarly not restricted to an electrical heating element.
  • the heating element could, for example, be a solar heating element, or a chemical heating device which produces heat in response to a chemical reaction.
  • the heating element could also be a combustion device, in which a fuel and oxidizer are combusted to produce heat.

  • More than one heating element can be included in the present invention, and can be located in one or more locations in the base. When a provision for a light source is included (as discussed in further detail below), one or more heating elements can be disposed in one or more locations around and adjacent the provision for a light source.
  • the device 10 is configured to receive a container 18 upon the heating element 14.
  • the heating element When power is applied to the heating element and the temperature of the heating element begins to rise, heat transfer from the heating element to the container warms or heats the aromatic material. As the temperature of the aromatic material begins to rise, aroma is released into the atmosphere at an increased rate.
  • the upwardly extending side wall 16 is comprised of an insulating material, the insulating side wall 16 will serve to retain heat inside the bottom portion of the container to more efficiently heat the aromatic material in the container 18. Additionally, as discussed above, the side wall 16 can also act as a barrier to restrict lateral movement of the container and thereby reduce spillage of the aromatic material.
  • the present invention thus provides an aromatic substance heating device that can be used with a variety of aromatic materials to emit a pleasant aroma.
  • the container 18 can be of any shape or substance that provides the desired heat transfer effects and is compatible with the desired heating element configuration.
  • any type of aromatic substance known in the art including scented wax, oil, or potpourri may be used with the present invention.
  • the present invention can be used with a conventional scented wax candle (not shown) which can be placed on the heating element 14 and warmed to an elevated temperature. As the candle is heated, the aroma from the wax is released at an increased rate.
  • the present device thereby provides a system for enjoying scented candles without requiring that the candle be lit. Because combustion of candles can lead to undesirable combustion byproducts, the device provides a healthier and cleaner alternative to burning scented candles. It is understood that the device is not limited to use with scented candles, but can be used with alternate aromatic materials, as discussed further below.
  • the present invention can be operated for many hours without requiring close supervision.
  • the device can be used in areas where open flames are not allowed, such as office buildings, dormitories and apartment complexes. Because the device does not burn the aromatic substance, when used with a conventional candle, it can dramatically extend the life of the candle. It is also believed that, when used with conventional candles, the present invention extracts a higher degree of aroma from the candle, in contrast to the aroma released when burning the candle.

The pressure switch can be configured to automatically initiate the heating element when a container is placed on the heating element.
