Abstract
Abstract The device comprises a combustion chamber into which smoking material is disposed for burning, and has means for igniting the smoking material. A first conduit communicates the combustion chamber with a conduit-terminating mouthpiece, and a second conduit communicates the combustion chamber with an air pump. Accordingly, the combustion chamber is intermediate the pump and the mouthpiece, so that the pump forces air through the second conduit, to and through the chamber, and to and through the first conduit, serially. In one embodiment of the device, a water chamber is interposed between the combustion chamber and the mouthpiece to serve as a smoke washing filter.
