ABSTRACT:
An aroma generator has a toroidal incense container with a toroidal channel and cylindrical walls. A toroidal channel floor is extended in a plane perpendicular to an axis that is common to the cylindrical walls of the toroidal channel. A bulb-attachment wall having a central bulb orifice is extended inward radially at a design distance from a base of the toroidal incense container. A cover plate is held in a covering position over the toroidal channel by attachment appendages on a cylindrical attachment sleeve. At least one attachment appendage is extended outward radially from a distal end of the cylindrical attachment sleeve and positioned in at least one arcuate attachment channel in an outside surface of the inside cylindrical wall for attachment of the cover plate to the aroma generator. A plurality of spacer ridges are extended radially from the cover plate to provide aroma-discharge passages between the cover plate and top edges of the toroidal channel. A resistance heater is positioned in the channel floor and optionally in channels walls to activate emission of aroma from toroidal incense material positioned in the toroidal channel. The resistance heater can be divided into segments to protect structural integrity. An approximately hemispherical light dome is positioned centrally on the cover plate and extended in an opposite direction from the cylindrical attachment sleeve. A toroidal bulb socket made of rubber or rubber-like material is extended inward radially from the bulb-attachment wall. A Christmas tree light bulb or other similar light bulb can be inserted in the toroidal bulb socket and extended into the light dome on the cover plate.
