Abstract
An air quality modification apparatus for dispensing a volatile material, such as for scenting the air, controlling pests, allergen control, or the like, includes an electric motor having a rotor and a coil. When electric current is applied, the coil produces both heat and an electromagnetic field that causes rotation of the rotor. A source of the volatile material is located adjacent to the coil so as to be volatilized by the coil's heat. An impeller, attached to the rotor, moves air across the volatile material and blows the vapors away from the apparatus. Energy efficiency is provided by employing the electric motor coil as the source of heat to vaporize the volatile material. Also disclosed is a refill supply of a volatile material for use with such an air quality modification apparatus.
