Abstract
Pipe for cigarettes, cigars and other tobacco articles, provided with a holder with a receiving hollow at one end for the cigarette, that is connected through a smoke channel with a mouthpiece at the other end of the holder, an apparatus being fixed in the smoke channel for purifying the smoke, said apparatus comprising a catalytic afterburner for the complete smoke flow with which the incompletely burnt hydrocarbons and carbon monoxide are being burnt more completely, the nicotine and tar contents being reduced substantially, said afterburner having a catalytic operation, and comprises an electric incandescent body.
Claims15
A pipe for use in connection with the smoking of cigarettes, cigars and other tobacco articles, said pipe having:
- a receiving hollow at one end to receive the article to be smoked;
- a mouthpiece;
- a smoke channel communicating said mouthpiece with said receiving hollow;
- and
- an apparatus fixed in said smoke channel to purify the smoke;
- said apparatus for purifying the smoke comprising catalytic afterburner means operable to catalytically oxidize incompletely burned hydrocarbons and carbon monoxide and to reduce, substantially, the percentage of nicotine and tar in the smoke passing through said catalytic afterburner means;
- said catalytic afterburner means comprising a spiral-shaped catalyst extended in the direction of flow of smoke and disposed in said smoke channel in the path of smoke passing therethrough, to force the smoke to flow in contact with said spiral shaped catalyst along an extended path.
In a pipe for use in connection with the smoking of cigarettes, cigars and other tobacco articles, said pipe having a receiving hollow at one end to receive the article to be smoked;
- a mouthpiece at the other end, and a smoke channel communicating said mouthpiece with said receiving hollow;
- the improvement comprising in combination:
- an apparatus fixed in said smoke channel to purify the smoke, said apparatus for purifying the smoke comprising catalytic afterburner means operable to catalytically oxidize incompletely burned hydrocarbons and carbon monoxide and to reduce, substantially, the percentage of nicotine and tar in the smoke passing through said catalytic afterburner;
- and,
- a capillary inlet passage disposed through the wall of the pipe upstream of the catalytic afterburner and having substantially the same sucking resistance as a cigarette (20 cm wc), the fall in pressure over the capillary being similar or equal to a cigarette or another smoking article, to provide additional air to the smoke stream without substantially affecting the smoking comfort of a person using the pipe.
