ABSTRACT:
The top surface of an electrode type vaporizer water container has a water inlet covered by a safety cover having an apertured concave portion through which the terminal pins of the electrodes are exposed. A detachable electric power source connector is insertable into the concave portion for engagement with the terminal pins for supplying power to the electrodes. A stopper pin on the connector cooperates with a stopper projection on the container adjacent the terminal pins to prevent the engagement between the connector and pins unless the cover, which as provided with a stopper pin release means, is properly positioned on the container. The engagement of the connector with the terminal pins locks the safety cover in position on the container making it impossible to remove the cover while the connector is so engaged. The safety cover arrangement prevents the supply of water into the container through the inlet with the electrodes electrically energized. The steam nozzle of the vaporizer projects through the cover and includes a convex upper edge which prevents blockage of the nozzle by a planar object laid thereon. The steam nozzle includes a concave part having steam outlets in the bottom wall thereof so arranged that an object dropped into the nozzle will not block the outlets. Projections are provided at the steam outlets to permit condensed water to drain rather than clogging the outlets.
