Description

Safety type cigarettes

The utility model relates to tobacco product, specifically a kind of smoking article with safety shutdown performance.

To be that a part of crowd is indispensable in daily life have a liking for product to cigarette.Because number of smokers is many, the scope of application is wide, so annual all have a lot of rising to abandon the fire that stub causes by the smoking people, this brings very big harm to the people's lives and property.For addressing this problem, people are seeking always, are developing a kind of cigarette that stub is extinguished automatically, in the hope of reducing the fire hazard that smoking brings to society to greatest extent.CN88101296 discloses a kind of cigarette that can extinguish automatically, this cigarette includes tobacco section, the main points of design are at an end of every cigarette a kind of miniature self-extinguishing water pipe that seals to be installed, utilize the automatic fusing of fire of cigarette self to seal, make water in the water pipe flow out, put out by water the fire of cigarette end automatically, reach the purpose of the fire that extinguishes cigarette end automatically.Though this method has the fire prevention effect, its complicated process of preparation, cost of manufacture height are unfavorable for extensive employing.

The purpose of this utility model will provide a kind of fire safety and manufacture craft simple safety type cigarettes exactly.

The purpose of this utility model is achieved in that designed safety type cigarettes includes smoke and filter tip, and the main points of design are to be provided with the space between smoke and the filter tip, and smoke and filter tip fasten as one by fire-retardant paper web.

So the cigarette of design is owing to have smoke and the space of filter tip formation in fire-retardant paper web, when smoking, cylindrical shell is inside and outside can to form certain pressure differential, under the effect of suction force when smoke burning becomes the lighter stub of weight, stub can enter in the fire-retardant paper web automatically, this significantly reduces with regard to the contact-making surface that makes stub ember and oxygen, thereby makes the stub ember from putting out from going out.In addition, when people's smoking is drawn to stub when very thin, also can stub be blown through by its air-flow that forms under the effect of cylindrical shell external and internal pressure difference, stub ember natural wind goes out.Can avoid the fire of the external initiation of stub ember thus effectively.

Be described in further detail the utility model below in conjunction with accompanying drawing.

Fig. 1 is a structure meaning diagrammatic sketch of the present utility model.

As shown in Figure 1, the utility model has smoke 3, filter tip 1, and smoke 3 and filter tip 1 wrap tightly by fire retardant papers, form fire-retardant paper web 4.Fire-retardant paper web 4 can adopt paper tinsel gold paper, and paper tinsel gold paper web will be longer than filter tip 1, and with filter tip wrap up in be contained in, one end of smoke 3 is also wrapped up in and is contained in the paper tinsel gold paper web, between smoke 3 and the filter tip 1 space 2 will be arranged at interval, this space 2 is preferably 0.2-0.4, to guarantee having enough pressure differentials in the paper web.Joint portion at fire-retardant paper web 4 and smoke 3 preferably is provided with adhesive tape 5, can strengthen smoke 3 and fire-retardant paper web 4 tightness like this, when smoke burns to adhesive tape, adhesive tape is burned, lose cohesive action, stub extinguishes after entering in the fire-retardant paper web 4 under action of pressure automatically.
