Abstract
An electrically heated chemical delivery system which is connectable with an electrical receptacle includes a housing with at least one opening therein. A heat actuated chemical pouch is disposed within the housing adjacent to at least one of the openings. A printed circuit board is disposed within and carried by the housing. The board carries a plurality of electrical components thereon, including at least one heater and a light. The board has at least two electrical contacts connected with the electrical components and positioned on an edge thereof. A base is attached with the housing. At least two electrical conductors are carried by the base. Each electrical conductor includes a first terminal end extending from an exterior of the base and a second terminal end engaged with a respective one of the electrical contacts. The first terminal ends are connectable with the electrical receptacle.
