With the increased smoking control movement and the increased health consciousness of people, new tobacco products have been developed vigorously in recent years. The novel tobacco product adopts a heating and non-combustion mode, reduces harmful components generated by high-temperature combustion cracking of tobacco, and greatly reduces the release amount of chemical components in mainstream smoke. Meanwhile, different from the conventional cigarette which still generates a lot of smoke when smoldering, the sidestream smoke and the environmental smoke of the cigarette can be greatly reduced, and the contradiction between smoking and smoking ban in public places is relieved to a certain extent.
However, the cigarette has small smoke volume and low smoke concentration when the novel cigarette is not combusted by heating, the adsorption performance of the conventional filter stick can further reduce the satisfaction of consumers, and the problem that the total smoking amount is increased on the contrary because the smoking frequency is increased is also easily caused; moreover, the cigarette is generally too short and too thin, and particularly, a smoking set needs to be adopted for continuous heating, so that the temperature of smoke sucked into the oral cavity of a human body is high, and the smoke has burning sensation. These can greatly affect the smoking taste of such cigarettes and reduce the satisfaction of smokers. Thereby affecting the acceptable degree of the cigarettes and failing to achieve the purpose of reducing the harm of the cigarettes. Therefore, a cigarette filter stick capable of effectively reducing the temperature of taste smoke and keeping the smoke concentration as much as possible is needed.
A great deal of research work with great effect is carried out on the aspects of cigarette filter tip materials and structures inside and outside the industry. The results of the former people show that the smoke temperature of the filter tip of the traditional cigarette can reach 70-80 ℃ at most in the first 2-3 mouths of smoking near the end, the smoke temperature of the filter tip even reaches more than 100 ℃ in a deep smoking mode, and the overhigh temperature of the filter tip not only influences the interception effect of the filter tip on smoke aerosol particles in the filter tip, but also influences the acceptance of consumers on the smoke sensory quality. There are also researches on adding a half-width partition guide plate or a micropore device in the filter stick to guide the smoke to flow so as to achieve the effect of intercepting the smoke. And the design of adopting polylactic acid film, aluminum foil paper and the like as the cigarette filter stick to reduce the smoke temperature. However, regulating and controlling the smoke temperature and improving the smoke sensory quality are always the key points and difficulties in the design of the novel cigarette filter stick which is not combusted by heating.

In addition, in the process of smoking cigarettes, the side, close to the heating area of the smoking set, of the acetate filter stick sections has the bad phenomena of fusion and agglomeration under the influence of high-temperature smoke, so that the smoking resistance is increased and the smoke amount is obviously reduced from the third opening and even the second opening of smoking. The 0D # acetate filter stick is more serious. The composite filter sticks of No. 11 and No. 12 have the function of reducing the temperature of smoke, so that the phenomenon is not obvious.
The filter stick reduces the adsorption of cigarette smoke and the maximum smoke temperature at the lip end of the outer edge of the filter tip. Effectively reduces the interception and adsorption effects of the cigarette filter stick on the smoke of the novel heating non-combustible cigarette, reduces the mouth feel temperature of the smoke of the cigarette, improves the sensory quality of the cigarette and promotes the satisfaction of consumers.
