1. A cartridge-type aroma percolator comprising:

  • (A) a container having an inside bottom surface, an electrical heater secured to the inside bottom surface and a removable vented cap; and

    (B) a replaceable cartridge telescopically received in said container, said cartridge being constituted by a can having a toroidal insert permeable to liquid secured at a position adjacent the top of the can and arranged so that it extends across an entire cross section of the can, the can and insert definining a chamber in the can below the toroidal insert that is partially filled with a pool of an aqueous solution of liquid fragrance, said insert having a hollow core and incorporating a porous pad surrounding the core, and a tube coaxial with the can extending through the hollow core of the insert, the lower end of the tube forming a liquid inlet immersed in the pool, whereby when the heater in the container is energized, the liquid in the can in a region above the heater is boiled to produce a gas pressure in a head space located above the pool in the chamber, forcing the liquid up the tube discharging it from the outlet thereof and showering it down on the insert thus percolating it through the pad before returning it to the pool, an aromatic vapor being exuded from the pad and discharged into the atmosphere through the vented cap, and whereby when the liquid is exhausted, one may dispose of the spent cartridge and replace it with a fresh cartridge; and

    (C) removable cover means for hermetically sealing said can, and for storing the contents thereof, while the cartridge is not in use.
