Electrical evaporator including fan and louver structure

An evaporator, comprising:

• a bottle containing a substance to be evaporated;
• a wick, having a lower portion disposed within the bottle and an upper portion protruding from the bottle, for drawing the substance to be evaporated from the bottle toward the upper portion of the wick;
• a housing in which the bottle is retained;
• means, within the housing, for creating an airstream;
• and means for directing the airstream upwardly and away from the upper portion of the wick.

A plug-in evaporator for dispersing a chemical active into a surrounding environment, the evaporator comprising:

• a bottle containing a liquid formulation including at least one chemical active;
• a wick, having a lower portion disposed within the bottle and an upper portion protruding from the bottle, for drawing the liquid formulation from the bottle toward the upper portion of the wick;
• a housing in which the bottle is detachably retained;
• an electrical heating device, disposed within the housing at a position proximate to the upper portion of the wick, for enhancing evaporation of the liquid formulation from the upper portion of the wick;
• a fan, disposed within the housing, for creating an airstream that entrains the evaporated liquid formulation;
• and
• an electrical plug, extending from the housing, for supplying power to the heating device and the fan and for supporting the evaporator in a wall outlet, wherein the housing includes a plurality of louvers located downstream from the fan for directing the airstream created by the fan upwardly and away from the heating device and the upper portion of the wick, the louvers being inclined at an angle between about 20 degrees to about 60 degrees relative to horizontal when the evaporator is in an upright position.
