Embodiment 1

[0033] The invention provides a cigarette filter tip, one end of the filter tip is a shredded tobacco end, the other end is a suction nozzle end, and the Na 2 HPO 4 12H 2 O 7.3 grams, urea 1.9 grams, CaSO 4 2H 2 O 0.8 g, stirred and melted at 50-70°C, placed in an ice bath to crystallize, and repeated melting and crystallization 5 times. During the last melting, spray 70 mg on the cellulose acetate filter rod tow taken out from the cigarette filter, then insert the filter rod into a low-temperature environment, let the phase change material crystallize well, and then insert the filter rod into the filter tip In the process, the cigarette filter tip is obtained; then the cigarette filter tip and shredded tobacco are made into a cigarette, and smoking is carried out.

[0034] According to the results of smoking evaluation, after adopting this method and technology, there is no obvious change in the aroma of the cigarette, and there is no obvious peculiar smell in the smoke. ...

Embodiment 2

[0036] The invention provides a cigarette filter tip, one end of the filter tip is a shredded tobacco end, the other end is a suction nozzle end, and the Na 2 HPO 4 12H 28.7 grams of O and 1.3 grams of urea were stirred and melted at 50-70° C., put into an ice bath to crystallize; the melted crystallization was repeated 5 times in total, and the prepared phase-change heat storage material was obtained. Weigh 60 mg of the phase-change heat storage material, add it between two filter rods of a cigarette, and obtain a cigarette filter tip; then make a cigarette from the cigarette filter tip and shredded tobacco, and conduct smoking evaluation.

[0037] According to the results of smoking evaluation, after adopting this method and technology, there is no obvious change in the aroma of the cigarette, no obvious peculiar smell in the smoke, the smoke is moist and natural, the consistency of the same cigarette is good before and after smoking, and there is no burning sensation in th...

Abstract

The invention discloses a cigarette filter tip and a cigarette. Phase transition heat storage materials are added on the end face of one end of the filter tip or in the filter tip close to the end face, and the phase transition temperature of the phase transition heat storage materials ranges from 15 DEG C to 90 DEG C. The smoke can be further cooled and filtered by the addition of the phase-transition heat storage materials in the cigarette filter tip, the phase-transition heat storage materials absorb heat during the self phase transition, the smoke hot burning sensation of smoking can be reduced, the moisture comfort feeling of the smoke can be improved, and harmful substances entered into the mouth are effectively reduced.

Description

technical field [0001] The invention relates to a cigarette filter tip and a cigarette, belonging to the field of tobacco. Background technique [0002] When traditional cigarettes are burned, the temperature of the combustion cone can reach above 800°C. When puffing, although the unburned shredded tobacco at the rear end and the filter tip can condense and cool down the mainstream smoke entering the filter tip, the mouth still often has a hot feeling, especially when the last few puffs close to the filter tip are drawn. The burning sensation is more pronounced. This not only easily makes the feeling before and after smoking inconsistent, but also often feels uncomfortable symptoms such as hot prickles in the mouth. In addition, a variety of harmful substances (such as polycyclic aromatic hydrocarbons) produced by high-temperature combustion are more likely to enter the mouth with aerosols at higher temperatures, and have a greater impact on human health. At the same time...
