Description

Binary composite cigarette filter rod capable of reducing smoke temperature and cigarette comprising same

Technical Field

The utility model belongs to the technical field of the cigarette technique and specifically relates to a can reduce smoke temperature's binary composite filter rod for cigarette and contain its cigarette.

Background

The phenomenon that the temperature of smoke rises often appears along with the combustion cone is close to the end of the filter rod at the rear section of cigarette smoking, consumption experience is influenced, part of cigarette consumers can feel that the lip end is scalded, the temperature of smoke in the oral cavity is high, and the smoke has great irritation when flowing through the throat and the nasal cavity. In order to solve the problem of overhigh smoke temperature in the smoking process of cigarettes, the cigarette specification is changed in part of cigarette product designs, and limited cooling effect can be realized due to the size change of a filter stick, but the smoking resistance of the cigarettes is increased, so that the light smoking experience of consumers in the smoking process is influenced.

Most filter sticks of cigarettes sold in the market adopt acetate fiber tows as production raw materials, but acetate fiber materials are difficult to degrade in natural environment, and if cigarette butts are discarded in the natural environment, soil and water sources are easily polluted due to the difficulty in degradation.

Therefore, how to fully utilize the design of materials and structure to develop a degradable cigarette filter stick with the effect of reducing the smoke temperature and apply the degradable cigarette filter stick to cigarettes is urgent need and trend of cigarette innovation and development.

In order to solve the above problems, the utility model is provided.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the defects existing in the prior art, and provides a degradable binary composite plant polysaccharide aerogel cigarette filter rod capable of reducing the smoke temperature and a cigarette containing the filter rod.

In order to solve the technical problem, the utility model discloses a realize through following technical scheme:

the utility model discloses a first aspect provides a binary composite filter rod for cigarette capable of reducing smoke temperature, the filter rod for cigarette has an air passage axially penetrating through the filter rod, the filter rod for cigarette comprises a first part 1 close to the far lip end and a second part 2 close to the near lip end; wherein the first part 1 is a cylindrical filter stick, and the second part 2 is a filter stick with a hollow cavity 21; the cross-sectional shape of the hollow cavity 21 is selected from: circular, rectangular, square, trapezoidal, pentagonal, equiangular triangular, or equiangular hexagonal.

Preferably, the filter stick for the cigarette is a plant polysaccharide aerogel filter stick.

Preferably, the plant polysaccharide aerogel filter stick is selected from konjac polysaccharide aerogel

Preferably, the plant polysaccharide aerogel filter stick is prepared by drying, freezing and extruding plant polysaccharide.

The utility model discloses a degradation of being heated of plant polysaccharide aerogel plays the effect to the flue gas cooling. The smoke that the tobacco section produced reaches second part 2 through the inside hole of the plant polysaccharide aerogel cylinder stick of first part 1, and the hollow cavity 21 of second part 2 can assemble the smoke, makes smog volume more sufficient. Furthermore, due to the existence of the hollow cavity 21, the contact area between the smoke and the filter stick is increased, so that the cooling effect on the smoke is further improved. In addition, as the first part 1 is a cylindrical filter stick, smoke is uniformly dispersed in the section, and after reaching the second part 2, the smoke is gathered in the hollow cavity 21 and then dispersed in the oral cavity of a user, and the smoke is loosened, gathered and loosened to flow through the hollow cavity, so that a Venturi effect is generated, the temperature of the smoke flowing through the hollow cavity is further reduced under the action of the Venturi effect, and the comfort of the oral cavity and lips during suction can be improved due to the reduction of the temperature of the smoke.

In addition, because the second part 2 is provided with the hollow cavity 21, the suction resistance can be reduced, and the feeling of relaxation of a user in the suction process can be improved.

In addition, the plant polysaccharide aerogel raw material for manufacturing the filter stick can be completely degraded, so that the pollution of the used filter stick to the environment is reduced.

The utility model discloses the second aspect provides one kind and contains the utility model discloses the first aspect cigarette of filter rod for cigarette.

Compared with the prior art, the utility model has the advantages of as follows:
