Safety cigarette

Abstract

The invention relates to the cigarette field. Technical problem to be solved is to overcome the defect of the existing cigarettes. The invention provides safety cigarettes that have high safety and greatly lower fire hazard initiation rate. The structure of the cigarette is that a rigid fire-retardant layer is embedded into the rice paper of the cigarette, and the fire-retardant layer is reticular. After the cigarette is ignited, tobacco shred burns inside the fire-retardant layer, and the reticular structure ensures unobstructed burning. Due to the rigid structure of the fire-retardant layer, the cigarette still keeps the reticular tube-shaped structure while burning. The tube-shaped fire-retardant layer separates the burning surface form the external, ensure that the burning front is not connected with the external, therefore, though the burning cigarette is discarded, the possibility that the burning surface is connected with the external is small, and a fire is difficult to be caused, thus greatly improving the safety of the cigarette.

Description

technical field [0001] The invention relates to the field of cigarettes, in particular to a safe cigarette capable of reducing the incidence of fire. Background technique [0002] In many cases, fires, especially forest fires, are caused by littering cigarette butts. Many people will habitually throw cigarette butts anywhere, when the cigarette butt is still burning or thinks that the cigarette butt has been extinguished, but it has not been extinguished. The burning temperature of cigarettes is very high, and the shredded tobacco is easy to re-ignite. Even if there is still a little spark, it can re-ignite. When there are flammable materials nearby, it is very easy to cause a fire. Because cigarettes are elongated, after the cigarette butt is discarded, it is in a horizontal state in many cases, and the burning point is on the side, which is very easy to ignite the surrounding combustibles. On the other hand, it is the shaking of soot. Many people will shake off the soot ...

AI Technical Summary

Problems solved by technology

Cigarettes burn at a high temperature, and the shredded tobacco is easy to re-ignite. Even if there is still a little spark, it can re-ignite. When there are flammable materials nearby, it is very easy to cause a fire

Because the cigarette is long, after the cigarette butt is discarded, it is in a horizontal state in many cases, and the burning point is on the side, which is very easy to ignite the surrounding combustibles

Another aspect is the shaking off of soot. Many people will shake off the soot anywhere, but in many cases part of the tobacco has not been completely burned, and it is easy to cause a fire at this time.
