Abstract
An electrically energized vaporizing unit for medications, room deodorizers, room scenting compounds, room insecticides, and the like, which is simple and inexpensive in its construction and which is compact in size. The vaporizing unit includes a housing having a central slot for holding a compressed paper fiber pad which is impregnated with the substance to be vaporized. The pad is heated by a pair of electrical heating elements which are located in the housing and positioned on opposite sides of the slot for maximum vaporizing efficiency of the pad. The housing may also contain paraffin wax. The melting point of the wax is selected to correspond to the vaporizing temperature of the particular substance in the pad. The vaporizing unit is provided 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 thermostat.
