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

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] The present invention is designed as figure 1 The safe cigarette with the structure shown includes a tobacco part 1 and a filter part 2 wrapped in a cigarette paper 3, and a rigid flame-retardant layer 31 in the shape of a honeycomb network is embedded in the cigarette paper 3. The flame retardant layer 31 extends forward to the front end of the tobacco part 1, partially covers the end of the tobacco part 1, and leaves an ignition hole 4, extends backward to the filter part 2, and covers 2 / 5 of the length of the filter part 2. The diameter of the above-mentioned ignition hole 4 is 3.5 mm, and the mesh area of ​​the flame-retardant layer 31 is 5 square millimeters.

[0018] As can be seen from FIG. 2 , the specific structure of the cigarette paper 3 is formed by embedding a flame-retardant layer 31 in the paper material 32 , which facilitates the ignition of the...

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 ...
