AI Technical Summary

Technical Problem

In existing granular cigarettes, the smoke-generating particles tend to flow when the cigarette is placed horizontally, resulting in uneven heating and affecting the smoke generation effect. Furthermore, the presence of porous fasteners increases the length of the cigarette.

Method used

The smoke-generating section structure with a skirted isolator includes a tube body, a sealing element, and a rear isolator. The rear isolator consists of a rear sealing diaphragm and an annular frame. The skirt extends towards the lip end and is connected by a crease line. The valve design allows for the flow of smoke. The sealing element is press-fitted to the tube body and is made of paper material for its environmental friendliness and biodegradability.

Benefits of technology

It effectively blocks smoke particles without increasing the length of the cigarette, is suitable for non-insertion heating methods, ensures smooth flue gas flow, and is made of environmentally friendly and easily degradable materials, reducing equipment investment costs and providing more employment opportunities.

Abstract

The present application belongs to the field of heating cigarettes, and particularly relates to a smoking segment with a skirt edge spacer, a preparation method thereof and a granular cigarette. The smoking segment comprises a tube body, a blocking piece arranged at a distal lip end of the tube body, a rear end spacer arranged at a proximal lip end of the tube body, and a blocking piece and a rear end spacer. The rear end spacer arranged at the proximal lip end of the tube body blocks the smoking granules and realizes ventilation at the same time in the smoking segment of the present application. The blocking piece at the distal lip end of the tube body comprises two schemes: scheme one, the blocking piece is the same as the rear end spacer, and the smoking segment or cigarette is suitable for various non-insertion type heating mode smoking devices; scheme two, the blocking piece is a front end spacer, which has a "cross" shaped frame opening, and can block the smoking granules and facilitate the insertion of the heating element.
