ABSTRACT:
The device draws the smoke up from lit cigarettes and the like and disperses it thoroughly in large amounts of air to make it nearly invisible and less offensive. A battery operated motor drives an impeller which draws smoke through a ram tube. The smoke then proceeds through an annular flow channel and passes through a perforated dispersal ring before being ejected through a dispersal rim slot near the top of the device. The flow path is arranged to minimize the drain on the batteries and maximize dispersal; the motor, its batteries and electrical circuit connectors (including a novel electrical switch) are arranged such that smoke and ashes are kept away from their compartment. The entire device disassembles easily for cleaning. In one embodiment, the smoke passes through an ash screen having a low resistance to air flow. In another, there is no screen or filter at all, but the smoke may pass along (not through) an absorbant material which may be saturated or otherwise provided with chemicals which reduce the amount of harmful ingredients in the smoke and/or deodorize the smoke. Additional containers of such chemicals may be provided in the device.
