Embodiment 1

[0056] figure 1 It is a schematic cross-sectional view of the aerosol cooling element 2 of the present invention.

[0057]As mentioned above, the aerosol cooling element 12 of the present invention is composed of several cellulose acetate sheets 10 that are freely stacked and wrapped with molded paper 13 on the outside, and the cellulose acetate sheets 10 are separated from each other. The cellulose acetate sheets 10 of the present invention are allowed to overlap at a certain inclination angle; the aerosol cooling element 12 can be formed by free stacking of cellulose acetate sheets 10 with different lengths, widths and thicknesses, as long as the size It is sufficient to be within the aforementioned numerical range.

[0058] Further, the length of the cellulose acetate sheet: width=(1-10):1, in an optional embodiment, may be a 4mm*18mm sheet, or a 4mm*4mm sheet, or other sizes. For example, in a cylindrical cavity with a diameter of 7mm and a length of 18mm, sheets of diff...

Embodiment 2

[0083] Figure 4 The axial schematic diagram of the mouth stick embodiment 2 made for the aerosol cooling element shown in embodiment sample 8 and sample 9, as Figure 4 As shown, the cellulose acetate nozzle stick includes a cellulose acetate mouthpiece 11, an aerosol cooling element 12, a molding paper 13, and a hollow cellulose acetate tube 14; the cellulose acetate mouthpiece 11, the cooling section 12, the The hollow cellulose acetate tubes 14 are connected in sequence to obtain the mouthpiece of the present invention, and a heated cigarette product can be obtained by combining the front end of the hollow cellulose acetate mouthpiece 14 with a 13mm tobacco segment.

[0084] The diameter of the composite nozzle rod is 7.2 mm, the inner diameter of the hollow acetate tube 14 is 3.0 mm, and the length is 7 mm; the cellulose acetate mouthpiece 11 is single denier 20 / total denier 27000, and the suction resistance is 9.1 Pa / mm of cellulose acetate tow tip, 8mm long.

Abstract

An aerosol cooling element is formed by free accumulation of cellulose acetate sheets, and the cellulose acetate sheets are separated from each other. The width of the cellulose acetate sheet ranges from 2 mm to 5 mm, the length of the cellulose acetate sheet ranges from 4 mm to 25 mm, and the thickness of the cellulose acetate sheet ranges from 0.2 mm to 1 mm. The cellulose acetate sheet comprises cellulose acetate and a modifier. The modifier comprises a plasticizer and/or polyol. The invention further discloses a preparation method of the cellulose acetate sheet and a filter rod capable ofbeing used for heating cigarettes, the aerosol cooling element is adopted in a cooling section, and a hollow section, the aerosol cooling element and a mouthpiece section are sequentially connected inthe axis direction of the filter rod and are formed by wrapping forming paper. When being applied to heating cigarettes, the element has the advantages of strong high-temperature thermal deformationresistance, high material safety and the like, can achieve the technical effects of reducing the smoke temperature of the cigarettes, low suction resistance and low smoke adsorption, improves the sensory comfort of smoke, and enhances the smoking experience of consumers.

Description

technical field [0001] The invention belongs to the technical field of tobacco and relates to an aerosol cooling element which can be used for heating cigarettes. Background technique [0002] Heated cigarettes are a new type of tobacco product. Most of the smoke aerosol products are completely wrapped by heating appliances. At a heating temperature of 250-300°C, the temperature of the smoke produced is relatively high, and the temperature in the first three puffs can reach 55- At 65°C, the amount of smoke released is 5% of that of traditional cigarettes. [0003] In order to reduce the smoke temperature and smoke filtration efficiency of heated cigarettes, some materials and mouth rod structures different from those used in conventional cigarettes have been developed and applied. For example, CN104203015B provides an aerosol-generating article with an aerosol cooling element. The cooling element used With 300mm per mm 2 -1000mm 2 The total surface area; patents CN1074580...
