Abstract
Abstract An electrically heated vaporizer comprises a base and an annular container removably mounted thereon. The base has means for connection to an electrical power supply and includes a broad lower portion and a narrower upper portion. The lower and upper base portions constitute an enclosed housing wherein an electrical resistance heating means is mounted and connected to the connection means. The container has an inner and an outer wall defining therebetween an interior annular chamber wherein an annular carrier for a substance to be vaporized is arranged. The inner wall of the container fits over the upper base portion and a bell-shaped rotary member is mounted on the upper end of the container. The upper end of the outer container wall defines outlet port means for the substance vaporized by electrical heating and the rotary member defines corresponding port means arranged to be moved into register with the container wall port means by rotation of the rotary member whereby the latter port means may be gradually opened and closed upon rotation.
