Background
In recent years, with the enhancement of public awareness of cigarette harmfulness and the increase of government regulation of cigarettes, the international traditional cigarette market is gradually sliding down, and meanwhile, the new tobacco products are rapidly growing in a reverse manner. The sales volume of the heated cigarettes is increased year by year, and particularly, the electrically heated type heated cigarettes are popular in the market, and the technology maturity and the smoking experience of the electrically heated type heated cigarettes are far ahead of other novel tobacco products.
In the process of implementing the present invention, the inventor finds that there are at least the following problems in the prior art:
1. during the heating and smoking process of the electrically heated cigarette, the substance released by the smoking medium may be greatly attenuated or fluctuated as smoking progresses. The general method is to carry out certain adjustment by adjusting the heat release curve of a heat source or changing the material of the smoking medium, but the condition of the smoking medium release fluctuation in the smoking process cannot be effectively changed.
2. At present, the temperature for heating the non-combustible cigarette is lower in order to ensure that the tobacco is not combusted, and is about 300 ℃, so that the release of substances required in the smoking medium for heating the cigarette is limited, and the release efficiency is lower. In order to improve the release amount of substances in the smoking medium, the heating temperature is generally improved, and at present, the heating temperature is improved to about 350 ℃, so that the temperature resistance of the cigarette paper wrapping the smoking medium is higher, otherwise, the cigarette paper is easy to carbonize and break, and the smoking medium is difficult to take out of a smoking set after smoking, so that the smoking experience is influenced.
3. In addition, the improvement of the utilization rate of heat is also the direction of continuous research on heating cigarettes.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problems, the present invention is provided.
The utility model provides a heating cigarette capable of improving the smoking stability and the heat utilization rate, wherein the smoking medium section of the cigarette comprises a smoking medium rod 1 and a composite cigarette paper 2;
wherein the composite cigarette paper 2 is wrapped on the periphery of the smoking media rod 1;

Preferably, the thickness of the graphite paper layer 2b is 40-100 μm.
Preferably, the coating layer 2c is a smoke agent coating layer and/or a flavor coating layer.
Preferably, the coating layer 2c is made by coating the second cigarette paper layer with the desired additives.
Preferably, the additive applied by the coating layer 2c includes a smoking agent, a perfume, or a mixture of a smoking agent and a perfume.
Preferably, the additive further comprises a gel. The gel is used for embedding the smoke agent and/or essence, so that the smoke agent and/or essence are volatilized and dissipated less.
The preparation method of the heating cigarette capable of improving the smoking stability comprises the following steps:
the smoking medium section is prepared by wrapping a smoking medium rod 1 with a composite cigarette paper 2, and the preparation method of the composite cigarette paper 2 comprises the following steps: the paper-based smoking medium rod is formed by bonding a first smoking paper layer 2a, a graphite paper layer 2b and a coating layer 2c through an adhesive layer 2m, wherein the coating layer 2c is in contact with the smoking medium rod 1.
The coating layer 2c is made by coating the required additives on the second cigarette paper layer.
Preferably, the second cigarette paper layer is cigarette paper with the gram weight of 20-40g per square meter and the air permeability of 30-1000 CU.
Preferably, the gram weight of the graphite paper layer 2b is 17-30g per square meter.
The technical scheme can be freely combined on the premise of no contradiction.
The utility model discloses following beneficial effect has:
1. the current method for solving the problem of fluctuation of the smoking medium release process in the smoking process is to change the structure of the cigarette body in ways of adjusting the heat release curve of a heat source or changing the material of the smoking medium and the like. The utility model discloses a new method is opened up, through the three layer construction that the compound cigarette paper 2 design that will wrap up the fuming medium is formed for the bonding of first cigarette paper layer 2a, graphite paper layer 2b and coating layer 2 c. The uniformity of the material release in the process of smoking is effectively improved, the smoking stability is better, and the amount of the smoke which can be smoked by 12 mouths is not obviously reduced.
2. The cigarette can improve the temperature resistance of the cigarette paper, and because the graphite has the high temperature resistance, the temperature resistance of the cigarette paper can reach 400-500 ℃ when the graphite is used in the air, and the temperature resistance of the graphite can reach 2500 ℃ when the graphite is used in vacuum or inert gas, the temperature resistance of the whole cigarette paper can be improved after the graphite paper is used in heating the cigarette, and the use requirement can be met.
3. Wrapping up tobacco core substrate after using aluminium foil and paper complex at present, making core substrate dry distillation effect better, the heat utilization efficiency promotes, and more even effectual being heated of core substrate, the release effect is better. However, the aluminum foil is compounded with the cigarette paper, so that certain requirements are imposed on the thickness of the aluminum foil, the use amount of the aluminum foil is increased, and the production cost is increased; meanwhile, the aluminum foil and the cigarette paper are combined to have thicker total thickness and higher gram weight, and the machine has poorer adaptability and higher waste when in use. The cigarette uses graphite paper to replace aluminum foil, and the graphite is lighter than the aluminum foil, so that the adaptability of the cigarette on a machine is good when the cigarette is used.
