Abstract

A heater arrangement for a volatile material dispenser includes a cylinder defining an opening and a resistor embedded in the cylinder. The dispenser further includes a housing configured to receive a refill containing a volatile material and a wick. The housing includes a first cavity configured to support the heater arrangement. Further, the dispenser is configured such that, when the refill is received within the housing, the opening receives the wick therein so that a radial gap is formed between the heater arrangement and the wick.
