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.
