Non-spitting noiseless electric steam vaporizer

摘要

A cool-running noiseless, non-spitting electric steam vaporizer has a liquid container with a top opening closed by a cap having a steam outlet and a vent opening. An inner housing cooperates with the cap to define a steam collection space communicating with the steam outlet and includes a depending heating chamber communicating with the steam collection space and surrounding a pair of electrodes extending into the container from the cap. An opening between the steam collection space and the container allows excess steam produced during periods of rapid boiling to flow to the container. An isolated conduit extending through the steam collection space from the container interior to the vent opening allows the excess steam to be exhausted without noise or spitting. An insulative double walled outer housing surrounds the heating chamber.
