ABSTRACT:
A candle-powered aroma generator in a lantern format housing a candle holder within a cylindrical container provided with a translucent shell mounted on a base and having a removable cover thereover whose roof has a central well. Below the bottom of the well is the burning wick of a candle supported in the holder, the candle flame heating the bottom which then functions as a miniature hot plate. Received in the well and resting on the hot plate is a replaceable aroma cartridge within whose cavity is a porous pad that partitions the cavity into upper and lower air chambers. The lower chamber is in heat transfer relation to the hot plate and the upper chamber has a vent therein. The pad is impregnated with a volatile liquid fragrance, and the heated air in the lower chamber produces a positive pressure therein which forces the air through the pad to volatilize the fragrance. The resultant vapor is discharged into the atmosphere through the vent.
