Abstract
A volatile material dispenser includes a housing configured to receive a refill containing a volatile material and a wick, the housing including a first cavity supporting a heater arrangement and a second, separate cavity supporting a fan arrangement for dispersing a vapor plume of the volatile material. The first cavity is substantially unobstructed between an upper, interior surface of the housing and an upper surface of the heater arrangement. The housing also includes an aperture through which the vapor plume exits the housing and a plurality of openings through which air from the fan arrangement directs the vapor plume away from the aperture. When a refill is received within the hosing, the upper surface of the heater arrangement is disposed nearer the aperture than a distal end of the wick, and a radial gap is formed between the heater arrangement and the wick.
