In one embodiment, the spiral rod 30 is a single spiral rod, the single spiral groove 70 of the single spiral rod is uniformly arranged around the rod axis 80 of the single spiral rod, the outer diameter surface of the single spiral rod (i.e. the outer diameter surface of the spiral 60) is in close contact with the outer wrapper 50 to form a single spiral channel, and both ends of the single spiral channel are respectively communicated with the limiting tube 90 and the filter tip 40 to form an air passing channel. As an embodiment, a cavity is further disposed inside the rod shaft 80 of the spiral rod 30, and the phase change energy storage material PCM is filled in the cavity.

As an embodiment, the aerosol-generating carrier 10 includes a reconstituted cut rolled stem, and the reconstituted cut rolled stem is formed by extracting cut rolled stems to reduce or remove soluble protein, soluble polysaccharide and soluble inorganic salt substances therein, and then refilling a predetermined aroma-generating substance into the cut rolled stems.

As an embodiment, the stem reconstruction of the aerosol generation carrier 10 is electrically heated at a temperature range of 200-.

The preparation method of the reconstituted cut stems contained in the aerosol generating carrier 10 comprises the following steps:

step 1: preparing tobacco stem shreds, and sequentially adopting the procedures of washing original stems, moistening the stems, pressing the stems, shredding, extracting, separating and drying the tobacco stem shreds to remove or reduce protein, polysaccharide and nitrate substances in the tobacco stem shreds and finish the preparation of blank stem shreds;

step 2: fully and uniformly mixing the tobacco aroma substances with the aerosol to obtain a mixture;

and step 3: and (3) feeding the materials prepared in the step (1) and the step (2) through a feeding device, fully and uniformly feeding the materials through an extrusion and homogenization process, and packaging for later use after water balance is carried out in a constant temperature and humidity process.

The aerosol comprises one or more of polyalcohol, ester of polyalcohol, polymer and long carbon chain monohydric alcohol. The aroma substances comprise one or more of volatile tobacco essential oil, volatile natural product essential oil, molecular distillation product of tobacco, and volatile edible essence.

The tobacco stems convey nutrients to the leaves in the tobacco growing process due to the special functions of the tobacco stems, so that the growth of the tobacco is promoted, and the tobacco stems also strengthen the tobacco. Because of its transmission function, its internal structure is porous and multi-channel, so that it can form its special structure and effect, and said characteristic is a character which is not reached by general natural material.

The invention fully utilizes the special structure and the effect of the tobacco stem material, particularly after the tobacco stem is extracted and processed, the effective material containing space of the tobacco stem is improved, and the inherent bad smell released after the tobacco stem is heated is avoided.

The products seen on the market, which are caused by the material of the smoke matrix, have heavy baking paper smell and insufficient smoke quantity in the heating process (the tobacco sheets are used as the smoke carrier, a certain amount of wood fiber is required to be added due to the strength requirement of the sheet preparation, the baking paper smell is generated in the heating process, in addition, due to the limitation of the material, more aerosol can not be added, and the amount accounts for 30 percent in the smoke matrix at most, so the smoke quantity is limited);

CN106723282A describes that the tobacco product smoke amount is improved by using the good absorbing capacity of porous tobacco stalk shreds for the atomizing agent, but the negative effect of the stalk shreds on the smoking taste of the tobacco product is not considered, and the situation that the tobacco product is not burnt by electric heating is not involved.

Generally, heating a non-combustible tobacco product requires heating the tobacco substrate to above 200 ℃ to produce a nicotine-containing aerosol. With continuous smoking of smokers, the tobacco substrate is continuously heated, and the protein and sugar in the heated body are charred along with the rise of temperature, so that unpleasant burnt smell is given out.

Aiming at the self defect that the existing stem material is suitable for being heated and not combusted, the invention provides a specially-made reconstituted stem shred, which is formed by extracting general tobacco stem shreds, reducing or removing protein, polysaccharide and nitrate substances in the tobacco stem shreds, and then refilling predetermined aroma substances into the tobacco stem shreds. Because of the substances such as protein, polysaccharide and nitrate in the tobacco stalk shreds, when the tobacco stalks are heated in the electric heating temperature range, the polysaccharide and the protein can generate burnt smell, and the taste of a smoker is seriously influenced. In addition, nitrate in the common tobacco cut stems is heated and decomposed to generate nitrite (amine), which can cause harm to human bodies, and the possibility of generating toxic gas by thermal decomposition of part of nitrate is fundamentally avoided. The aerosol generating carrier adopts the specially-made reconstituted cut stems, and can well overcome the defects of the common cut stems of the tobacco during electric heating.

Tobacco stem material includes raw stem material, cut stem material, granulated stem material, and stem powder, whether puffed or not, within the ranges we describe. In the examples, the form of the cut rolled stem is preferable from the viewpoint of convenience in processing and use.

The comparison of the extracted cut stems with the original cut stems:

through extraction, more than 90% of water-soluble substances in the stem materials are removed, and the weight of the stem materials is reduced by half compared with the original weight. Due to the elimination of the water-soluble substances, the space for the stem materials to absorb the materials is increased, and more importantly, the chemical components which are inherent in the stem materials and generate bad smell at high temperature are eliminated, so that the method has obvious advantages; the removed protein can avoid the feather burning smell generated when the smog substrate is heated;

after extraction, most of sugar is removed, so that scorched smell (including scorched smell generated when polysaccharide starch and pectin are heated) can be avoided;

through extraction, nitrate is basically eliminated, so that the possibility of generating nitrite (amine) through thermal decomposition of nitrate and the harm to the health of smokers are greatly reduced; in addition, the possibility of generating NO2 toxic gas by the thermal decomposition of part of the nitrate is fundamentally avoided.
