Abstract

An electrically energized vaporizing unit for medications, room deodorizers, room scenting compounds, room insecticides, and the like, is provided which is simple and inexpensive in its construction and which is compact in size. The vaporizing unit has one or more compartments which are adapted to be filled with a liquid to be vaporized, or to hold a solid tablet saturated with a substance to be vaporized, the compartments being heated by positive thermal coefficient (PTC) electrical heating elements in conjunction with paraffin wax, the melting point of the wax being selected to correspond to the vaporizing temperature of the particular substance in the compartments. The vaporizing unit is equipped with an electric plug which may be directly plugged into an electric receptacle to energize the PTC heating elements, and it does not require a switch or protective thermostats.
