Cooling pipe for cigarette, preparation method of cooling pipe and cigarette with cooling pipe

Abstract

The invention discloses a cooling pipe for a cigarette, a preparation method of the cooling pipe and the cigarette with the cooling pipe. The cooling pipe for the cigarette is in a hollow pipe shape.The cooling pipe for the cigarette sequentially comprises a shell, a damp-proof layer, a functional carrier and a cooling layer from outside to inside. The cooling layer is loaded on the first side ofthe functional carrier; the damp-proof layer is loaded on the second side, opposite to the first side, of the functional carrier; the functional carrier is connected with the inner wall of the shellthrough the damp-proof layer; the damp-proof layer is used for preventing external moisture from entering the cigarette cooling pipe to be in contact with the cooling layer; and the cooling layer is used for reducing the temperature of flue gas. According to the invention, the cooling effect can be improved, and the damage to the appearance and the quality of the cigarette caused by the moisture absorption characteristic of the cooling material can be prevented.

Description

technical field [0001] The invention belongs to the field of low-temperature cigarette cooling technology and technology, and in particular relates to a cooling tube for cigarettes, a preparation method thereof, and a cigarette with the cooling tube. Background technique [0002] Because the low-temperature cigarette is shorter and the smoking part is heated throughout the heating process, although its heating temperature is much lower than the temperature at which shredded tobacco burns, the temperature of the smoke produced when it is smoked is much higher than that of traditional cigarettes. The current mainstream low-temperature cigarette brands in the international market generally have a maximum smoke temperature above 50°C (Celsius), which is located in a range that is relatively sensitive to consumer experience. If it is not controlled, excessively high temperatures may still affect smoking. Therefore, the problem of cooling is still an important issue that cannot be...

Problems solved by technology

Studies have shown that the cooling design of the two methods of simultaneously composite structure cooling and material cooling has good application prospects, but many phase change materials with good cooling functions usually have certain moisture absorption properties
