Background
The low-temperature cigarette, also known as a heated cigarette or a heated non-burning cigarette (heat-not-burn cigarette), heats the tobacco substance by an external heat source, and the atomized medium, the flavor components and the additional flavor in the tobacco substance generate smoke similar to the smoke of the traditional cigarette burning and smoking by heating, so that the consumers can obtain physiological satisfaction. The tobacco substances in the low-temperature cigarette are only heated but not combusted, so that the harmful components and the biotoxicity of the smoke are greatly reduced, and the side-stream smoke and the environmental smoke are also greatly reduced.
The atomized medium, the flavor components and the external flavoring in the tobacco material release atomized smoke to enter the oral cavity of a consumer through the filter section under the condition of heating temperature (250-350 ℃ (centigrade)), and the smoke temperature is obviously higher than the temperature of the smoke entering the oral cavity during the traditional cigarette smoking, thereby greatly influencing the smoking experience of the consumer. Therefore, reducing the temperature of the smoke of the low-temperature cigarette is one of the core technologies.
In the prior art, two methods are generally used for reducing the temperature of the smoke of the low-temperature cigarette: one method is to use a cavity mouth rod or adopt a complex design to lead the smoke to pass through a longer gas path in the mouth rod, thereby increasing the residence time of the smoke in the mouth rod and leading the smoke to have more time for heat exchange, however, because the length and the diameter of the mouth rod are limited, the cavity mouth rod or the complex design leads the smoke to have limited cooling effect when the smoke passes through a longer gas path in the mouth rod, wherein, the complex design leads the longer gas path of the smoke in the mouth rod to lead the production process and equipment of the mouth rod to become more complex; the other method is to directly use heat storage materials in the filter rod to cool the high-temperature atomized smoke flowing longitudinally. However, in the prior art, the heat storage material, especially the cooling tip rod prepared in a film form, melts when the surface of the tip rod contacts high-temperature flue gas, so that on one hand, a flue gas channel is blocked, the subsequent heat storage material is difficult to contact the high-temperature flue gas, the cooling effect of the heat storage material is affected, and even the flue gas amount is sharply reduced; on the other hand, the hardness, the suction resistance and other physical properties of the filter stick are changed, so that the appearance of the filter stick is changed, and the consumption experience is influenced.
