Flame-retardant fireproof cigarette

Abstract

A flame-retardant fireproof cigarette comprises a tobacco body (4), a filter core (11) joined end-to-end with the tobacco body (4), a flame-retardant fireproof sleeve (2)covering all or a part of the tobacco body (4) and a filer paper sleeve (1) covering the filter core (11). The flame-retardant fireproof sleeve (2) is sequentially divided into a flame retardant area (22) for preventing combustion and a ventilation area (23) provided with short slits or pores (5a). The ventilation area (23) of the flame-retardant fireproof cigarette is divided into a plurality of sections connected with one another by a plurality of burn-out lines (6), or a raised ventilation passage (5) is disposed on the ventilation area (23). A burned part of the flame-retardant fireproof cigarette during smoking can automatically segmentally fall off along with thermal fusing of the burn-out lines (6), thus retaining original smoking status and feeling. Air enters combustion spots of a cigarette butt from the ventilation passage and the ventilation slits or pores attached to the ventilation passage under suction force so as to guarantee sufficient combustion of a cigarette butt and smooth smoking, and the cigarette butt cannot be extinguished easily.

Description

technical field [0001] The invention relates to a cigarette, in particular to a flame-retardant and fire-resistant cigarette which can reduce fires caused by burning cigarette ends. Background technique [0002] According to China's "Fire Protection Yearbook" statistics: there are about 10,000 fires (reaching the fire level) caused by smoking in my country every year, causing economic losses in the hundreds of millions. Therefore, it is a better choice to prevent fire accidents from the source to provide smokers with a cigarette that can reduce the ignition rate so as to reduce fires caused by smoking. At present, the flame-retardant and fire-resistant technologies of cigarettes invented abroad are basically adding chemical flame retardants to the cigarette paper or surrounding the chemical flame-retardant strips around the cigarette paper at the end of the cut tobacco body. The cigarette butt will be extinguished by itself due to lack of oxygen. During the smoking process ...

AI Technical Summary

Problems solved by technology

At present, the flame-retardant and fire-resistant technologies of cigarettes invented abroad basically add chemical flame retardants to the cigarette paper or surround the chemical flame-retardant strips around the cigarette paper at the end of the cut tobacco body. The cigarette butt will be extinguished by itself due to lack of oxygen. During the smoking process, the chemical reaction of the chemical flame retardant or the flame retardant strip will change the taste of the cigarette, resulting in dry mouth and pain after smoking. Cigarettes are still exposed to open flames during smoking, and the ignition rate is still quite high
