A heating non-combustible product belongs to a novel tobacco product combining traditional cigarettes and electronic products, and is characterized in that a cigarette is not directly combusted, but tobacco materials are heated by means of electric heating, carbon heating, physical and chemical reaction heating and the like to release smoke, the same satisfaction as that of the traditional cigarette is provided for consumers, and meanwhile, various harmful components generated by cracking in the high-temperature combustion process of the tobacco are reduced to reduce harmful components in mainstream smoke, so that the harm of the tobacco to human health is reduced.
Research shows that in the smoking process of the traditional cigarette, the combustion temperature can reach 800-. To reduce the release of harmful substances at high temperatures, the tobacco material in a heat-not-combustible product is typically heated in a heating appliance only to temperatures of 250-350 ℃ which allows for a sufficient and complete release of nicotine and some of the aromatic substances. On the other hand, the cigarette length of the existing heating non-burning cigarette is usually 45 mm-55 mm, and is shorter than that of the traditional cigarette, so that the temperature of high-temperature smoke generated by heating the tobacco material is higher than that of the smoke of the traditional cigarette when the high-temperature smoke reaches the oral cavity through the filter tip section without being processed. Due to the cigarette structure, the limitation of heating temperature and the like, the problems of insufficient smoke quantity, insufficient fragrance quantity, higher smoke temperature and the like of the non-combustible heating product are obvious. Therefore, the structure of the cigarette rod and the heating appliance needs to be improved to supplement the defects of smoke, insufficient aroma and the like. However, in general, since the non-combustible products are new types of tobacco products, the heating devices, cigarette sticks and other products used for preparing the tobacco are still in the process of continuous exploration and improvement.

Example 2
On the basis of the technical scheme of the embodiment 1, the inventor further optimizes part of parameter specifications, and the specific process is briefly introduced as follows.
During the optimization experiment, the prepared heating non-combustion cigarette with the hollow and groove structure has the structural aspect that the circumference of the cigarette is 23.0mm, and the length of the aroma producing section (tobacco section) is 15mm (the component is the aroma producing section of the heating non-combustion cigarette (Guangdong province gold leaf science and technology development Co., Ltd., dry method reconstituted tobacco leaf) processed by shredding tobacco sheets);
a filter section, which adopts a normal pressure drop filter rod and is made of acetate fiber tows; but adopts different length combinations;
the hollow cooling section (hollow groove rod) is prepared from acetate fiber tows, the cavity structure is in a hexagonal star shape, the diameter of the cavity is about 2mm, the diameter of the groove rod is about 3.5mm, the sectional area of the cavity is about 0.3 time of that of the groove rod, and the depth of the groove is 0.5 mm; but with different types of trenches and different numbers of trenches.
The specific experimental design results are shown in the following table:
in the above table, tobacco segment 15 represents a tobacco segment of 15mm in length; the number behind the four-edge groove, the six-edge groove and the eight-edge groove represents the length (unit, mm) of each type; the post-acetate filter digital description of the filter segment length (in mm); thin-walled paper tubes, thin-walled hollow filter rods (Padan Jiang cigarette Material works, Limited liability company).
The analysis of the above table shows that:
the combination of the six-edge groove filter stick and the eight-edge groove filter stick exists in the No. 1 and No. 2 structures, the groove positions of the six-edge groove filter stick and the eight-edge groove filter stick are distributed differently, so that the groove channel is blocked to a great extent, the actual production process cannot be controlled specifically, the suction resistance is larger compared with other structures, part of smoke has long retention time in a cooling section, and more fragrant substances are intercepted and adsorbed;
no. 3, No. 4 and No. 5 structures directly select hollow groove filter sticks, smoke generated by heating a tobacco section by a heat source mainly passes through a hollow part, and in addition, a part of the smoke passes through a groove channel to finally reach a filter tip section, but because of the difference of the hollow groove structures, the contact area of an eight-edge groove is more, the heat exchange area with the smoke is larger, the cooling effect is better, and because the space between four-edge grooves in the No. 5 structure is large, a peripheral cavity formed after wrapping forming paper is large, the supporting effect cannot be achieved, and the hardness is poorer;
the structures No. 6, No. 7 and No. 8 increase the length of a cooling section, reduce the length of a filter tip section, keep the total length of the cigarette unchanged, lower the temperature of smoke entering an oral cavity, reduce the filter tip section to enable the smoke quantity to be larger, enable the aroma to be fuller and enable the overall experience of the octagonal groove of the structure No. 6 to be better;
the No. 9 and No. 10 structures are made into a two-section type composite structure on the premise of keeping the total length of the cigarette unchanged, most of smoke generated by heating the tobacco section by a heat source directly enters an oral cavity through a hollow part, the cooling effect is poor, no filter tip is trapped, the smoke aerosol has strong granular sensation and heavy impurity gas;
the No. 11 and No. 12 structures also keep the total length of the cigarette unchanged, the cooling section material is changed into a thin-wall paper tube and a thin-wall hollow filter rod, the two materials have no groove structure and large cavity area, the smoke passing speed is higher, the cooling effect is poor, the temperature of an inlet cavity is high, and the smoking experience is poor.
The comprehensive results show that: the cigarette structure is selected to be 15mm of tobacco section, 28mm of octagonal groove and 7mm of acetate fiber filter tip, the cigarette circumference is 23mm, the smoke temperature of the cigarette entering the mouth cavity is moderate, the number of suction openings is large, the satisfaction is strong, the smoking experience is good, and the cigarette structure is an optimal structural design.
