Description
Technical Field
The invention relates to the technical field of tobacco, in particular to a cigarette cartridge for heating cigarettes.
Background
At present, when the cigarette is heated for smoking, no matter peripheral heating or inner core heating is carried out, the heat conduction is not uniform enough, atomization media, flavor components and additional essence and spice contained in tobacco substances cannot be effectively atomized and volatilized, and the smoking experience that a smoker cannot be satisfied by an atomization effect is poor.
The heated cigarette is relatively short and the whole smoking part is heated in the heating process, so that the heating temperature of the heated cigarette is far lower than the combustion temperature of tobacco shreds, but the temperature of smoke generated when the heated cigarette is smoked is far higher than that of the traditional cigarette. At present, the mainstream low-temperature cigarette brand in the international market has the highest smoke temperature of more than 50 ℃ and is located in a region sensitive to the experience of consumers, and if the cigarette brand is not controlled, the safety of smokers can still be damaged by overhigh temperature.
The tobacco core material of the heating cigarette mostly uses tobacco shreds and slices, and glycerin with higher content is added, and the addition amount of the glycerin in some products can reach 50%. Glycerin is a polyol compound, has a plurality of hydroxyl groups, can form chemical bonds with water molecules, and thus has certain hygroscopicity. When the moisture-absorbed heated cigarette is heated, water vapor is brought out by the smoke gas, so that the cooling effect of the smoke gas can be reduced, and meanwhile, the thin sheet is easy to damp and mildew in the storage process.
In the prior art, regarding the research on increasing the atomization effect of heating cigarettes, a person skilled in the art usually adds a heat conduction auxiliary agent in the preparation process of a tobacco sheet so as to improve the heat conduction performance of the sheet and increase the atomization effect. The research on the temperature reduction of the heated cigarette generally stores, absorbs and transfers heat by adding a heat absorbing material in a temperature reduction section. The cigarettes used by iQOS marketed by Felmo International use polylactic acid as a cooling material to reduce the temperature of the smoke to below 40 ℃. In the research on moisture resistance of heated cigarettes, a novel humectant is generally used to replace glycerin which is easy to absorb moisture.
In the prior art, no matter a heat conduction auxiliary agent is added into a special slice, the heat conduction performance of the slice is improved, and the atomization effect is increased; the novel humectant is used for replacing glycerin to prevent moisture; new materials are introduced, and the taste is influenced to a certain extent. Melting phenomenon can appear after phase change cooling material PLA thin slice contacts high temperature flue gas in the cooling section, leads to flue gas passageway to block up, influences cooling material's cooling effect, smog volume when can appearing two mouthfuls after the suction is showing and is reducing scheduling problem even.
At present, a method for achieving moisture resistance by sealing the end part of a cigarette core section of a heated cigarette is reported, and a cigarette cartridge with a cooling and moisture-proof function for increasing an atomization effect is designed, so that the method has great significance for the application of the heated cigarette.

The relevant performances of the comparative examples and the examples are evaluated, and the following aspects are specifically included:
1. heat conductivity
The thermal conductivity of the cartridges prepared in this comparative example and example was measured using a thermal conductivity tester, and the measurement results are shown in table 1.
TABLE 1 thermal conductivity of different samples
As can be seen from Table 1, the heated cigarette cartridge prepared in example 1 of the present application has high thermal conductivity, so that when the heated cigarette is heated, the heating heat can be conducted rapidly and uniformly.
2. Cooling effect
Simulating smoking according to a cigarette smoking model specified in national standard YC/T29-1996, and detecting the temperature of the central position of the middle section of the cigarette filter stick when smoking the non-combustion tobacco product heated by the heating non-combustion cooling section of the invention by using an IQOS heater and a K-type thermocouple temperature detector, wherein the result is shown in Table 2;
TABLE 2 temperature detection results (. degree. C.) of cigarette smoke heated without burning using the cooling unit of the present invention
As can be seen from Table 2, the heated cigarette cartridge prepared in example 1 of the present application has the best cooling effect, and can reduce the temperature of the smoke to below 40 ℃ on average.
The results clearly show that the heating and non-combustion tobacco product using the heating and non-combustion cooling unit has obvious effect of cooling the smoke, improves the smoking experience of consumers, improves the smoking experience, and meets the psychological and physiological requirements of the consumers.
3. Moisture resistance
The change of the moisture content of the cartridges after sealing the ports at both ends for 24 hours at a humidity of 60% and a temperature of 22 ℃ and the maximum smoke temperature of the cartridges (as shown in table 3) were measured by gas chromatography and thermocouple thermometry in comparative example and example;
TABLE 3 moisture Change and maximum flue gas temperature conditions
| Sample (I) | Increase in Water content (mg/24 h) | Maximum flue gas temperature (. degree. C.) |
| Comparative example 1 | 11 | 55.1 |
| COMPARATIVE EXAMPLE 2 (non-hygroscopic layer) | 5 | 50.0 |
| COMPARATIVE EXAMPLE 3 (without dampproof course) | 10 | 48.1 |
| COMPARATIVE EXAMPLE 4 (No Cooling layer) | 4 | 53.1 |
| Comparative example 5 | 3 | 48.2 |
