ABSTRACT:
An inhalator comprises a water level adjusting chamber which fluidly communicates a water supply chamber and a vaporizing chamber. A manually operable valve interrupts communication between the level adjusting and vaporizing chambers. Upon closing of the valve, a power supply circuit is turned on to energize a heater for heating water in the vaporizing chamber. The interruption of communication between the level adjusting and vaporizing chambers during the use is effective to obtain only a relatively small amount of water to be heated.
