Abstract

Abstract The invention relates to a smoking appliance and includes first and second chambers connected by a conduit to permit the passage of air from one to the other through a quantity of lighted tobacco. A source of compressed air is connected to one of the chambers and a flexible tube including a mouthpiece is connected to the other chamber whereby smoke may be delivered under pressure to the mouthpiece. In a preferred embodiment, the chamber to which the flexible tube is attached contains a quantity of water through which the smoke is forced by the pressurized air supply before it flows into the outlet tube. The tobacco itself may be ignited by means of a flame-type lighter mounted within one of the chambers or by electrical means wherein a resistance element is positioned underneath the tobacco across the flow of fresh air to the tobacco.
