Abstract

The utility model relates to the field of cigarettes, mainly aims to overcome the fault of the prior cigarette, and provides a cigarette which has high security and enables fire trigger rate to be greatly reduced. The structure of the cigarette is that a rigid flame-retardant layer is embedded in the cigarette paper of the cigarette; and the flame-retardant layer adopts a reticulate structure. When the cigarette is ignited, the shredded tobacco burns in the flame-retardant layer; the reticulate structure of the flame-retardant layer ensures the smoothness of the burning of the shredded tobacco. As the flame-retardant layer adopts a rigid structure, the cigarette still adopts the reticulate pipe structure after burning; as the reticulate flame-retardant layer separates the burning surface from the external world, the burning surface is ensured in non-contact with the external world. Therefore, even a burning cigarette is discarded, the possibility that the burning surface is in contact with the external world is little; a fire is hardly caused; and the security of the cigarette is greatly improved.

Description

A kind of cigarette

Technical field

The utility model relates to the cigarette field, a kind of cigarette that can reduce occurrence index of saying so more specifically.

Background technology

Under many circumstances, causing under a lot of situations of fire, particularly brushfire causes owing to throwing out cigarette end without care.A lot of people understand habituation and lose cigarette end everywhere, when cigarette end still burns or thinks that cigarette end extinguishes, under the situation about not extinguishing as yet in fact.The temperature of cigarette combustion is very high, and the easy resume combustion of pipe tobacco, even also have some Mars to exist, also can resume combustion, and when near the very easy fire that causes when combustibles are arranged.Because cigarette is strip, after cigarette end is dropped, be horizontal state under a lot of situations, burning point is in the side, the combustibles around very easy the lighting.Be exactly shaking off of cigarette ash on the other hand, a lot of people can shake off cigarette ash everywhere, but the also incomplete after-flame of a lot of situation lower parts tobacco just causes fire this moment easily.

The utility model content

Technical problem to be solved in the utility model is the deficiency that overcomes existing cigarette, and a kind of high security that has is provided, and reduces fire initiation rate cigarette greatly.

The utility model is achieved through the following technical solutions:

The improving technology of the cigarette structure that the utility model is related is, the cigarette paper in the tobacco section of cigarette is embedded in one deck rigidity flame-retardant layer at least, and described flame-retardant layer is netted.After lighting cigarette, pipe tobacco is in the flame-retardant layer internal-combustion, and network structure guarantees the unobstructed property of burning.Because flame-retardant layer is a rigid structure, therefore still keep netted tubular construction after the cigarette combustion, the flame-retardant layer of tubulose has been isolated combustion front with extraneous, guarantee that combustion front does not contact with the external world, even therefore also be dropped aflame cigarette, combustion front is very little with the extraneous possibility that contacts, and very difficult meeting causes fire, has improved the security of cigarette greatly.

The flame-retardant layer of the present utility model hollow out that assumes diamond in shape is netted or the honeycombed hollow out is netted, and these two kinds of structures can guarantee to improve air circulation adopting minimum fire proofing can make maximum fretwork area, guarantee the smooth and easy of cigarette combustion, can not influence mouthfeel.On the other hand, rhombus or favose structure have very high structural strength, can guarantee that flame-retardant layer still keeps tubular structure behind high-temp combustion, for security provides safeguard.

In order further to improve security, flame-retardant layer extends to cigarette front end week edge, leaves fire hole in the middle of the cigarette front end, adopt the structure of packaging type can prevent cigarette initial stage of burning with regard to breaking out of fire.Fire hole is convenient to light cigarette, in order to guarantee to light fast cigarette, does not influence use, and the fire hole diameter is not less than 3 millimeters.

Because unburnt pipe tobacco also is a major reason that causes fire, and is an often uncared-for major reason, also be another crucial factor of fireproof if therefore avoid unburnt pipe tobacco to drop.The utility model is arranged on the mesh area of flame-retardant layer between 3～8 square millimeters, and in this areal extent, one side can be good at avoiding the pipe tobacco uncombusted and drops, and can guarantee that also cigarette ash can pass through smoothly.Briefly the mesh area is too little, and then cigarette ash is difficult to smooth and easy passing through, and influences cigarette and sucks effect; Too greatly then unburnt pipe tobacco drops easily, produces disaster hidden-trouble.And cigarette ash passes the Mars that can extinguish all existence behind the mesh, further improves security.

For the security that guarantees to suck with keep the fragrance of cigarette, the utility model flame-retardant layer is made by silicone plasties, particularly has more the organosilicon pure silicon ketone plastic of high stability and makes.The flame-retardant layer that adopts above-mentioned material to make has the higher rigidity characteristics, and stable in properties, and no impurity taste can not take place to mix flavor with pipe tobacco, has guaranteed the fragrance of cigarette.

The length of partly extending at filter tip for flame-retardant layer is less than 1/2nd filter length, and the smoker can not touch flame-retardant layer when containing the filter tip front end like this, the mouthfeel when influencing smoking.

Advantage of the present utility model is to be embedded at cigarette paper the flame-retardant layer of rigidity, adopts the packaging type structure, can effectively stop burning cigarette or cigarette end to contact with extraneous, reduces disaster hidden-trouble greatly.Adopt rhombus or favose flame-retardant layer structure,, improve structural strength, guarantee that flame-retardant layer can not rupture or be crooked in the cigarette combustion process in conjunction with specific fire proofing.Flame-retardant layer is at cigarette front end set-point fire hole, and terminal do not have all to cover the filter tip parts, and keeps higher hollow out and adopt stable material to make to the cigarette smoker providing the good mouthfeel of sucking, the traditional properties of assurance cigarette.In sum, the common cigarette of not having a flame-retardant layer with respect to prior art has outstanding substantive distinguishing features and obvious improvement.
