Patent ID: RE38686

Claim:
A smoke generating apparatus, comprising: a combustion chamber having an air flow inlet and an air flow outlet; a heating element disposed in the combustion chamber, the heating element having a central flow axis; a smoke generating fluid injection tube positioned along the central flow axis of in alignment with the heating element; means for conveying smoke generating fluid to the smoke generating fluid injection tube; and means for generating an air flow through the combustion chamber from the air flow inlet to the air flow outlet; at least two operating modes being provided including one operating mode in which power is supplied only to the means for generating an air flow from the air flow inlet to the air flow outlet and one operating mode in which power is applied to all systems to heat the heating element, inject smoke generating fluid by means of pressurized air onto the helical heating element and create and air flow of pressurized air to draw smoke out the outlet of the combustion chamber.
