Abstract

The invention discloses a low-suction-resistance low-filtration cooling composite cigarette filter tip. The filter tip comprises an ultrahigh single-denier cellulose acetate tow part, and the ultrahigh single denier cellulose acetate tow comprises greater than or equal to 10 deniers of single deniers. The filter tip also comprises a structure which can reduce the smoke temperature of a cigarette and is partially connected with the ultrahigh single-denier cellulose acetate tow. The filter tip also comprises a hollow pipe part which is connected with the ultrahigh single-denier cellulose acetatetow part; and the hollow pipe part is positioned at the upstream of the ultrahigh single-denier cellulose acetate tow part. The filter tip also comprises a structure which is capable of reducing thesmoke temperature of the cigarette and is positioned between the hollow pipe part and the ultrahigh single-denier cellulose acetate tow part. The structure capable of reducing the smoke temperature ofthe cigarette comprises any structural unit capable of reducing the smoke temperature and a filter stick formed by gathering particles. The composite filter tip not only can reduce cigarette pressuredrop and smoke adsorption, but also has a cooling effect, and can keep the comfort of a cigarette smoke inlet.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, and relates to a mouthpiece structure, in particular to a mouthpiece structure with cooling, low draw resistance and low filtering functions. Background technique [0002] Shredded tobacco for heated cigarettes is reconstituted tobacco leaves (tobacco flakes), which are extracted from traditional tobacco leaves, and the emissions of heated cigarette products are only about 5% of traditional tobacco. In order to further reduce the adsorption and filtration performance of the filter, it is necessary to develop products that meet the requirements of low suction resistance and low filtration, so as not to have a greater impact on the sensory quality of suction. At the same time, because the distance from the heating end to the mouth end of new tobacco products is shorter than that of ordinary cigarettes, it brings discomfort such as burning heat to smokers, and cooling the smoke is also an inevita...
