ABSTRACT:
A dual purpose electric vaporizer comprising a container having an electric heating element heated by an electric current, and the heating element connected to an external electric power source. The container has a double deck tablet containing means, for the tablets to be vaporized. The first of the deck containing means is placed at a position close to the heating element, and another deck is positioned at an elevated position above the first deck, at a substantial distance from the heating element. The first containing means can thus be loaded with an insecticide repellant tablet in the lower deck, having a higher evaporating temperature, and the upper deck can be loaded with an air freshener tablet evaporating at a lower temperature.
