Description

The present invention belongs to the technical field of cigarette production with respect to the temperature lowering filter rod, its use, and the cigarette.

In a conventional cigarette, when puffing, the amount of heat generated by the combustion cone of the cigarette is sent to the filter by mainstream smoke, and as the cigarette puff progresses, the temperature of the smoke flowing through the filter rises. Studies have shown that when the puff is about to finish, the temperature of the smoke on the filter side is as high as 70-80 ° C, and if the temperature of the filter is too high, the blocking effect of the filter will be impaired and the quality of the cigarette will be affected. It becomes clear that the sensory evaluation of consumers is also adversely affected. It is required to appropriately lower the smoke temperature.

The heated non-combustible cigarette generates smoke by heating the tobacco product through an external heating member. Normally, the tobacco product meets the atomization condition at 250 to 350 ° C. to secure the amount of smoke. In addition, low adsorption and non-adsorption are usually required on the filter side, and the temperature at which high-temperature atomized smoke enters the oral cavity through the filter becomes higher than the combustion temperature of conventional cigarettes. Therefore, proper reduction of smoke temperature is also an important technique studied for cold cigarettes.

Chinese patent CN201510045745.4 provides a filter and cigarette that lowers the smoke temperature by adding a phase change material on the filter side, and the phase change material used is a mixture of hydrated inorganic salt and urea. There is a method of using such a hydrated salt, which is known in the art by spraying on an acetate fiber filter or placing crystals between two filters. This effect is inadequate.

Chinese patent CN101396173 provides a method of cooling and retaining the temperature of a cigarette by vortexing, and a cigarette structure thereof, in which a vortex channel communicating with air is installed in front of the cigarette filter, thereby achieving a temperature lowering effect. It has a complicated structure and is not suitable for low temperature heating type non-combustible cigarettes.

The form of perfume granules, perfume wire or capsule is usually used for the perfume treatment on the filter. Chinese patent CN101390657 discloses a mint sustained release type filter rod for cigarettes and its production process, in which a fragrance means such as using cotton yarn soaked in fragrance is used, but continuous fragrance is not achieved. It is possible.

The technical problem to be solved by the present invention is that when puffing cigarettes (including conventional cigarettes and non-combustible cigarettes), the temperature of smoke generated by combustion is high, giving a burning sensation to the consumer's oral cavity and puffing.
