METHOD FOR CLEANING SMOKING PIPE IN COURSE OF SMOKING AND DEVICE FOR ITS IMPLEMENTATION (VERSIONS) Russian patent published in 2011 - IPC A24F9/06 

FIELD: tobacco industry.

SUBSTANCE: group of inventions relates to accessories for smoking pipe cleaning in the course of smoking and envisages four versions of the cleaning method: In accordance with the first version one blows a unidirectional air flow from the bowl towards the mouthpiece so that to force contaminants from the pipe channel and collect them on the filter. In accordance with the second version one provides for vacuum depression at the mouthpiece outlet with the contaminants sucked out and collected on the filter. In accordance with the third version one subjects the contaminants to inertia force impact with the contaminants removed from the pipe channel and collected on the filter. In accordance with the fourth version one subjects the contaminants to centrifugal force impact with the contaminants removed from the pipe channel and collected on the filter. Per each method a version of the device for its implementation is proposed. These cleaning methods are recommended for both straight and curved pipes. Notably, their application does not result in the pipe extinguishing but (with some versions of the device) on the contrary facilitate its ignition. Thus, after such express-cleaning completion, one may proceed with smoking the pipe.

EFFECT: improved efficiency of pipe cleaning and reliability of the proposed devices operation.
