A wick-based emanation device for dispensing a volatile liquid is
disclosed. The dispensing device includes a housing and a fan mounted in
the housing for generating an air stream used for dispersing the volatile
liquid. Walls of the housing form an enclosure for mounting the fan and
for receiving an exposed portion of the wick therein. A retention
structure is provided for coupling the wick to the housing and securing
the wick in the air stream generated by the fan. The volatile liquid
migrates along the wick from the reservoir to the exterior of the
container where it is evaporated from the surface of the wick by forced
airflow generated by a motorized fan mounted in the housing. The wick is
formed to have a width dimension W which does not exceed 1.2 times a
dimension R of a blade of the fan extending from the fan axis of rotation
to an edge of the fan blade farthest from the axis of rotation.
