[0013] In order to more clearly illustrate the technical solutions of the embodiments of the present disclosure, the following will briefly introduce the drawings needed to be used in the embodiments. It should be understood that the following drawings only show some embodiments of the present disclosure, and therefore should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can also be obtained without creative labor on the basis of these drawings.

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below. If the specific conditions are not specified in the embodiments, the conventional conditions or the conditions recommended by the manufacturer are used. If the reagents or instruments used are not specified by the manufacturer, they are all conventional products that can be purchased on the market.

[0017] The current mainstream aerosol product form is tobacco-oriented reconstituted tobacco or non-tobacco-oriented granular type, and the solid-state aerosol product (Solid aerosol products, hereinafter referred to as SAP product) has become an important research direction in this field due to its own advantages. Compared with the existing reconstituted tobacco and granular type, the advantages of SAP product are as follows:

[0018] 1. Better taste fidelity: This new type of product can better preserve the natural flavoring ingredients in tobacco, reduce the loss of aroma during processing, and provide a more authentic taste close to traditional cigarettes.

[0019] 2. Reduced raw material loss: The integrated process is the main one compared with the reconstituted tobacco type, which does not need to go through the complex tobacco reconstitution process, reducing the energy consumption and cost in the production process. Unlike the granular type product, which may have raw material loss due to particle breakage and scattering during filling and use, the SAP product can more effectively utilize tobacco material.

[0020] 3. Lower resistance fluctuation: Its uniform structure helps to reduce the resistance fluctuation during smoking, making the consumer feel more smooth when smoking.

[0021] However, the smoking segment of the SAP product has the problems of insufficient smoke generation, low smoke generation efficiency per unit time, soft and sticky itself, and easy to get wet, etc. The above problems will lead to poor subsequent processing performance, affecting the quality and use effect of the product. In order to overcome the above defects of the existing solid aerosol product, the present disclosure is proposed.

[0022] In a first aspect, embodiments of the present disclosure provide a solid combined aerosol product, which comprises a smoking segment and a filter segment; the smoking segment comprises a functional smoking segment and a solid core, wherein the functional smoking segment is used to provide aerosol, and the solid core is used to provide tobacco flavoring ingredients;

[0023] The solid core is provided with a through hole in the axial direction; the smoking segment and the filter segment are arranged in the axial direction, and one end of the functional smoking segment is connected with one end of the solid core, and the end of the solid core away from the functional smoking segment is connected with the filter segment.

[0024] It should be noted that the order of the smoking segment and the filter segment in the aerosol product can be adjusted, and in the present disclosure, the position of the functional smoking segment is set, i.e. as the edge segment of the solid combined aerosol product rather than the middle segment, i.e. one end of the solid core is connected with the filter segment, and the other end is connected with the functional smoking segment, and the solid core is in the middle position; this design takes into account the situation that the solid core is easy to shrink after being smoked and fall off, so the solid core is placed in the middle; in addition, since the solid core itself is usually brown or brown, it will become dark black after being smoked, and if it is exposed on the end face, it will affect the appearance and consumer experience.

[0025] In other embodiments of the present disclosure, one end of the solid core is connected with the functional smoking segment, and the other end of the functional smoking segment is connected with the filter segment, i.e. the design of the solid core in the edge position is also possible, but the periphery of the solid core needs to be further protected or optimized in appearance.

[0026] In the embodiments of the present disclosure, the through hole is provided in the axial direction of the solid core, which can reduce the resistance; if there is no hole, the resistance will be increased, which will hinder the release of aerosol of the functional smoking segment and the solid core segment, affect the smoking experience, and cause problems such as difficulty in smoking and small smoke.

[0027] In an alternative embodiment of the present disclosure, the raw materials for preparing the functional smoking segment include, by mass percentage of dry matter, 8-40% of the first smoke forming agent, 0.5-3.0% of the bulking agent, 22-45% of the porous fiber, 5-31% of the natural plant fiber, 0.5-6.5% of the binder, and 0-24% of the flavoring.

[0028] It should be noted that the functional smoking segment is composed of specific smoking materials, and its main function is to improve the smoking efficiency and the amount of smoke; the surface and the inner core of the prepared functional smoking segment have a porous structure, good aerosol generating capacity, and good sustainability.

[0029] In an alternative embodiment of the present disclosure, the first smoke forming agent includes polyhydric alcohols and derivatives thereof; preferably glycerol and propylene glycol, and the mass ratio of glycerol to propylene glycol is (70-97):(3-30).

[0030] It should be noted that the main function of the first smoke forming agent is to generate aerosol when heated, form smoke, and provide users with a visual and sensory experience similar to smoking.

[0031] The amount of the first smoke forming agent can be selected from any one of 8%, 10%, 13%, 18%, 20%, 24%, 30%, 35%, and 40%, or other values within the range of 8-40%, by mass percentage of dry matter. For example, when the amount of the first smoke forming agent is 10%, the amount of glycerol is 7-9.7%, and the amount of propylene glycol is 0.3-3%.

[0032] In an alternative embodiment of the present disclosure, the bulking agent includes at least one of povidone, polyvinylpyrrolidone, potassium aluminum sulfate, potassium hydrogen tartrate, sodium diacetate, sodium bicarbonate, potassium bicarbonate, and calcium hydrogen phosphate; preferably povidone, sodium bicarbonate, and calcium hydrogen phosphate, and the mass ratio of povidone to sodium bicarbonate to calcium hydrogen phosphate is (32-42):(29-39):(19-39).

[0033] It should be noted that the bulking agent helps to increase the bulkiness and porosity of the smoking material, reduce the adhesion, improve the air permeability, and help to form a porous structure, thereby improving the generation and sustainability of aerosol and increasing the amount of smoke.

[0034] The amount of the bulking agent can be selected from any one of 0.5%, 0.8%, 1.0%, 1.3%, 1.5%, 1.75%, 1.9%, 2.5%, 2.8%, and 3.0%, or other values within the range of 0.5%-3.0% by mass percentage of dry matter. Exemplarily, taking the amount of the bulking agent 1.0% as an example, the amount of povidone is 0.32%-0.42%, the amount of sodium bicarbonate is 0.29%-0.39%, and the amount of calcium hydrogen phosphate is 0.19%-0.39%.

[0035] In an alternative embodiment of the present disclosure, the porous fiber comprises at least one of cellulose acetate fiber, polycaprolactone fiber, phosphorylated cellulose fiber, chitin fiber, kapok fiber, and microcrystalline cellulose; preferably chitin fiber and kapok fiber, and the mass ratio of chitin fiber to kapok fiber is (25-53):(47-75).

[0036] It should be noted that the porous property of the porous fiber improves the air permeability of the material, helps to form a porous structure, easily adsorbs and stores the smoke forming agent, promotes the uniform generation of smoke, and improves the smoke generation rate.

[0037] The amount of the porous fiber can be selected from any one of 22%, 25%, 28%, 30%, 32%, 33.5%, 35%, 40%, 42%, and 45%, or other values within the range of 22%-45% by mass percentage of dry matter. Exemplarily, taking the amount of the porous fiber 30% as an example, the amount of chitin fiber is 7.5%-15.9%, and the amount of kapok fiber is 14.1%-22.5%.

[0038] In an alternative embodiment of the present disclosure, the natural plant fiber comprises at least one of hemp fiber, bamboo fiber, broadleaf wood fiber, coniferous wood fiber, and bamboo cane fiber; preferably hemp fiber, broadleaf wood fiber, and bamboo fiber, and the mass ratio of hemp fiber to broadleaf wood fiber to bamboo fiber is (25-35):(15-45):(20-60).

[0039] It should be noted that the natural plant fiber provides structural support, increases the stability and mechanical strength of the smoking segment, and enhances flexibility. In addition, the natural plant fiber also has the function of air permeability, and its loose structure can maintain the air flow inside the product, reducing the suction resistance.

[0040] The amount of natural plant fiber can be selected from any one of 5%, 8%, 10%, 12%, 15%, 18%, 20%, 23%, 28%, and 31%, or other values within the range of 5%-31% by mass percentage of dry matter. Exemplarily, taking the amount of porous fiber as 18% for example, the amount of hemp fiber is 4.5%-6.3%, the amount of broadleaf wood fiber is 2.7%-8.1%, and the amount of bamboo fiber is 3.6%-10.8%.

[0041] In an alternative embodiment of the present disclosure, the binder is selected from any one of cellulose derivatives, pectin, and plant polysaccharides.

[0042] It should be noted that the main role of the binder is to assist in molding and maintain structural stability. In the preparation process of the functional smoking segment, the binder helps to shape the mixture into the desired shape, improving production efficiency and consistency of product quality.

[0043] The amount of binder can be selected from any one of 0.5%, 0.8%, 1.0%, 1.5%, 2.3%, 2.8%, 3.5%, 4.6%, 5.2%, 6.0%, and 6.5%, or other values within the range of 0.5%-6.5% by mass percentage of dry matter.

[0044] In an alternative embodiment of the present disclosure, the flavoring agent is selected from any one of natural plant extracts and synthetic flavoring agents.

[0045] It should be noted that the flavoring agent can impart specific taste and aroma characteristics to the smoke, such as mint flavor, fruit flavor, tobacco flavor, etc., according to different needs and product positioning. In the process of preparing the functional smoking segment, reasonable adjustments can be made according to actual needs.

[0046] The flavoring agent can not be added, and its amount can be selected from any one of 0.1%, 1.8%, 2.3%, 5.0%, 7.5%, 9.6%, 15%, 17%, 18.5%, 19.25%, and 24%, or other values within the range of 0%-24% by mass percentage of dry matter.

[0047] As mentioned above, the use of bulking agent and porous fiber in functional smoking segment, and the use of hemp fiber or bamboo fiber in natural plant fiber. The composition of these materials makes the functional smoking segment form a high adsorption material, the fibers are interwoven into a skeleton under the action of the adhesive, and the bulking agent has a pore-forming effect, making the surface covered with numerous through holes, the use of natural plant fiber increases the contact area with air, enhances the air permeability of the functional smoking segment, and facilitates the smooth flow of air into the aerosol product from the bottom or the circumference during smoking. The adsorbed smoke forming agent and aroma forming component forms an aerosol, which is mixed uniformly with the aerosol generated by the solid core, and then released through the filter segment.

[0048] In an optional embodiment of the present disclosure, the raw materials for preparing the solid core include, by mass percentage of dry matter: 50%-80% of tobacco powder raw material, 3%-12% of second smoke forming agent, 10%-20% of powdered fiber, 0.5%-5% of binder, and 0%-25% of essence and spice.

[0049] It should be noted that the main function of the solid core is to supply tobacco aroma components, which cooperates with the functional smoking segment to play a "supplementary function", which can effectively improve the smoking effect of the whole product, and at the same time the processing performance of the product is improved, and the continuous production efficiency is greatly improved.

[0050] For example, the amount of tobacco powder raw material can be selected from any one of 50%, 53%, 55%, 63%, 65%, 70%, 72%, 75%, 77%, 78% and 80%, or other values within the range of 50%-80%, by mass percentage of dry matter; the amount of second smoke forming agent can be selected from any one of 3%, 5%, 7%, 7.5%, 9%, 9.6%, 11%, 11.5% and 12%, or other values within the range of 3%-12%. The amount of powdered fiber can be selected from any one of 10%, 12%, 12.5%, 14%, 14.5%, 15%, 16%, 18%, 18.5%, 19.25% and 20%, or other values within the range of 10%-20%. The amount of binder can be selected from any one of 0.5%, 0.8%, 1.3%, 1.75%, 2.5%, 2.75%, 3%, 3.45%, 3.8%, 4% and 5%, or other values within the range of 0.5%-5%. The essence and spice can not be added, and the amount thereof can also be selected from any one of 0.1%, 1.8%, 2.3%, 5.0%, 7.5%, 9.75%, 13%, 16.5%, 18.5%, 23% and 25%, or other values within the range of 0%-25%.

[0051] In an alternative embodiment of the present disclosure, the tobacco powder raw material is selected from any one of cut tobacco, tobacco shreds, tobacco fines, and tobacco rods; the mesh size of the tobacco powder is 50-150 mesh; preferably 80-120 mesh. Illustratively, the mesh size of the tobacco powder can be selected from any one of 80 mesh, 100 mesh, and 120 mesh.

[0052] It should be noted that the tobacco powder raw material provides aroma components and nicotine of tobacco, satisfying the pursuit of tobacco taste and physiological needs of smokers. The tobacco powder in this particle size range can be better mixed with the powdered fiber and other ingredients, providing sufficient specific surface area to enable maximum adsorption of flavoring agents, preventing the loss of flavoring agents from the solid core due to penetration, ensuring the amount of aroma of the solid core, and maintaining the stability of its aroma and taste.

[0053] In an alternative embodiment of the present disclosure, the second smoke forming agent includes polyhydric alcohols and derivatives thereof; preferably glycerol and propylene glycol, and the mass ratio of glycerol to propylene glycol is (68-98):(2-32).

[0054] It should be noted that the second smoke forming agent generates smoke when heated, simulating the smoke effect of traditional cigarettes and enhancing the smoking experience. The amount of smoke forming agent in traditional products is generally 15%-25%, and the amount of the second smoke forming agent in the present disclosure is reduced to 3%-12%, which not only meets the processing requirements but also solves the problems of soft adhesion and moisture absorption, and the storage time of the product is also extended from 3 months to more than 1 year.

[0055] In an alternative embodiment of the present disclosure, the powdered fiber is selected from any one of microcrystalline cellulose, chicory powder, resistant dextrin, and cellulose acetate butyrate.

[0056] It should be noted that the powdered fiber is used to provide structural support, increase the stability and mechanical strength of the solid core, and enhance flexibility and prevent cracking.

[0057] The type and function of the binder used in the preparation of the solid core are the same as those of the functional smoking segment, and the role of the binder at this point is to tightly combine the tobacco powder raw material, smoke forming agent, flavoring agent, and other ingredients, ensuring the structural stability of the solid core. It helps the solid core to maintain its integrity during production, storage, transportation, and use, and is not prone to scattering or breaking.

[0058] The type and function of the flavoring agent used in the preparation of the solid core are the same as those of the functional smoking segment, and the role of the flavoring agent is mainly to add rich and varied flavors to the solid core, improve and modify the original flavor of tobacco, and meet the taste preferences of different consumers. Create a unique aroma characteristic and enhance the pleasure of smoking. During the preparation of the solid core, reasonable adjustments can be made according to actual needs.

[0059] It should be noted that the solid core in the present disclosure is a solid core with an axial through hole, which facilitates the heat transfer of the heating source into the interior of the solid core, uniformly heats the solid core from the inside out, and significantly improves the heating efficiency.

[0060] Specifically, the structure of the solid core is shown in FIG. 2. As can be seen from FIG. 2, the solid core of the present disclosure can be designed as a concentric cylindrical structure with an axial single through hole structure according to actual needs, or can be designed as a structure with a groove axial center single through hole. In other embodiments of the present disclosure, a series of small through hole structures can be uniformly designed around the axial center according to actual needs, which can be rhombic, circular, triangular, sector-shaped, etc., and the center can not have a through hole. The structure of the single through hole can be adjusted according to the shape of the actual heating element, and can be designed in a circular, square, or other shape.

[0061] In an optional embodiment of the present disclosure, the length of the functional smoking segment is 3-15 mm; the length of the solid core is 3-22 mm, the circumference of the functional smoking segment and the solid core is 16-28 mm; the radial cross-sectional area of the axial through hole of the solid core is 15-65% of the radial cross-sectional area of the solid cylinder formed by the circumference and the length.

[0062] It should be noted that the length of the functional smoking segment and the solid core has certain requirements. The length of the functional smoking segment of 3-15 mm can basically ensure the smoke concentration, less than 3 mm the concentration is small, and more than 15 mm the concentration is too high to dilute the tobacco aroma components released by the solid core, affecting the tobacco experience of the solid core. The length of the solid core segment of 3-22 mm can basically ensure the supply amount of tobacco aroma components, less than 3 mm the tobacco experience is weak, and more than 22 mm the tobacco experience is not obviously improved but the production cost is increased. The radial cross-sectional area of the axial through hole of the solid core is required to be 15-65% of the radial cross-sectional area of the solid cylinder formed by the circumference and the length, less than 15% the resistance is large, the flow resistance of the aerosol in the through hole is large, the release efficiency is low, and more than 65% the unit weight of the solid core is small, the tobacco aroma components released are less, and at the same time the molding and processing difficulty of the solid core is large.

[0063] Exemplarily, the length of the functional smoking segment can be selected from any one of 3 mm, 4 mm, 4.5 mm, 7.5 mm, 9 mm, 12 mm, 13.5 mm and 15 mm, or other values within the range of 3 mm-15 mm; the length of the solid core can be selected from any one of 3 mm, 6 mm, 8.5 mm, 10 mm, 13 mm, 16 mm, 18 mm and 22 mm, or other values within the range of 3 mm-22 mm; the circumference of the functional smoking segment and the solid core can be selected from any one of 16 mm, 17.5 mm, 19 mm, 20 mm, 23 mm, 25.5 mm, 26 mm and 28 mm, or other values within the range of 16 mm-28 mm; the radial cross-sectional area of the axial through hole of the solid core, which is formed by the circumference and the length of the solid core, can be selected from any one of 15%, 29%, 24%, 28%, 35%, 40%, 48%, 55%, 60% and 65%, or other values within the range of 15%-65%.

[0064] In an alternative embodiment of the present disclosure, the porosity of the functional smoking segment is 45%-80%, the air permeability is 2000 mL / min-20000 mL / min, and the axial steady pressure draw resistance is 0.5 Pa / mm-20 Pa / mm.

[0065] Further, the porosity of the functional smoking segment is 53%-72%, and the air permeability is 6000 mL / min-16000 mL / min. Exemplarily, the porosity of the functional smoking segment can be selected from any one of 53%, 55%, 58%, 60%, 62.5%, 65%, 68%, 69.5%, 70% and 72%, or other values within the range of 53%-72%; the air permeability can be selected from any one of 6000 mL / min, 8000 mL / min, 9500 mL / min, 10000 mL / min, 12000 mL / min, 14000 mL / min, 15000 mL / min and 16000 mL / min, or other values within the range of 6000 mL / min-16000 mL / min; the axial steady pressure draw resistance is affected by the porosity and the air permeability of the functional smoking segment.

[0066] It should be noted that the functional smoking segment prepared by the present disclosure has high porosity and good air permeability, which has a positive effect on the improvement of smoking amount and smoking efficiency.

[0067] In an alternative embodiment of the present disclosure, the density of the functional smoking segment is 0.2 g / cm 3 -1.5 g / cm 3 , and the density of the solid core is 0.4 g / cm 3 -1.3 g / cm 3For example, the functional smoking segment can have a density selected from any one of 0.2 g / cm 3 , 0.8 g / cm 3 , 1.0 g / cm 3 , 1.2 g / cm 3 , 1.3 g / cm 3 and 1.5 g / cm 3 , or other values within the range of 0.2 g / cm 3 - 1.5 g / cm 3 ; and the solid core can have a density selected from any one of 0.4 g / cm 3 , 0.6 g / cm 3 , 0.85 g / cm 3 , 1.0 g / cm 3 , 1.2 g / cm 3 and 1.3 g / cm 3 , or other values within the range of 0.4 g / cm 3 - 1.3 g / cm 3 .

[0068] It should be noted that the functional smoking segment with a density within the appropriate range is easy to release aerosol and has a fast release rate, and the tobacco flavoring components of the solid core are easy to output. If the density is out of the range, the functional smoking segment has a slow release rate and cannot meet the demand for smoke amount, and the tobacco flavoring components of the solid core are difficult to output and cannot meet the demand for tobacco experience.

[0069] In an optional embodiment of the present disclosure, the solid core has a porosity of 0% to 20%, an air permeability of 0 mL / min to 100 mL / min, and an axial steady pressure draw resistance of 0.1 Pa / mm to 5 Pa / mm.

[0070] For example, the solid core can have a porosity selected from any one of 0%, 5%, 8%, 10%, 12.5%, 15%, 17.5%, 18.5%, 19% and 20%, or other values within the range of 0% to 20%; an air permeability selected from any one of 0 mL / min, 10 mL / min, 20 mL / min, 30 mL / min, 50 mL / min, 60 mL / min, 80 mL / min and 100 mL / min, or other values within the range of 0 mL / min to 100 mL / min; and an axial steady pressure draw resistance affected by the porosity and the air permeability of the solid core.

[0071] In a second aspect, the embodiments of the present disclosure provide a preparation method of the solid combination aerosol product as described above, which comprises:

[0072] The prepared functional smoking segment, solid core and filter segment are connected in sequence.

[0073] Specifically, the preparation method of the solid combined aerosol product is as follows:

[0074] The functional smoking segment and the solid core are prepared according to the material ratio; the prepared functional smoking segment, solid core and filter segment are assembled and connected in a predetermined order, and the specific structure is shown in FIG. 1.

[0075] It should be noted that, compared with the prior art, the present disclosure effectively solves the problems of low smoking efficiency per unit time, low smoke volume, easy to be damp, and poor subsequent processing performance of the traditional solid aerosol product by setting the functional smoking segment and optimizing the formula of the solid core. Not only the smoking efficiency and the smoking volume are improved, but also the stability and reliability of the product in the subsequent processing process are improved, which provides an innovative solution for the aerosol product field and has significant practical value. In addition, compared with the traditional single solid core aerosol product, the smoking start-up time of the solid combined aerosol product of the present disclosure is shortened by 15%, and the smoking volume is increased by more than 30% in the same working time. This improvement is verified by strict experimental tests.

[0076] The features and performance of the present disclosure are further described in detail below in conjunction with the embodiments. Embodiment 1

[0107] The comparative example 1 provides a solid combination aerosol product, which is different from the example 1 only in that (2) the solid core with axial through hole is prepared by deleting the raw material: 7.5% smoke forming agent, and the rest remains unchanged.

[0108] The preparation method of the comparative example 1 comprises the following steps:

[0109] The above raw material substances are mixed uniformly, and water is added to form a solid content of 80% of the solid core initial product.

[0110] The solid core semi-finished product with an axial central single through hole is prepared by an extrusion molding process through a mold, the hole diameter is 4 mm, and the outer circumference is 21.5 mm.

[0111] Drying at 75°C until the moisture content is (6±2)%, to obtain a traditional solid core product with an axial through hole, as shown in FIG. 2.

[0112] (2) Preparation of a traditional single solid aerosol product

[0113] The traditional solid core with an axial through hole and the binary filter rod are sequentially arranged and assembled in the axial direction to obtain a traditional single solid aerosol product.

[0114] In this test example, the solid combination aerosol products prepared in Examples 1-9 and Comparative Examples 1-8 and the traditional single solid aerosol product prepared in Comparative Example 10 are tested for smoke concentration and smoking efficiency, wherein the heating section length is kept consistent, and the filter section selected is a binary filter rod structure. The specific test method is as follows:

[0115] Under the same environmental conditions (temperature 25°C, humidity (35±5)%RH), heating is performed using a ring-type heating appliance, the smoke concentration is detected by a heating non-combustion comprehensive tester, the time from the start of heating appliance to stable smoking is recorded as a comparison of smoking efficiency, the average value of the 3rd-10th puffs is taken as the comparison of the amount of smoke generated in a fixed time, and the results are shown in Table 1. Table 1 Smoke concentration and smoking efficiency data of aerosol products

[0116] As can be seen from Table 1, the solid combination aerosol products of the present disclosure have obvious advantages in stable smoking start-up time and smoking amount. Among them, Examples 1, 2 and 3 show that the more the amount of swelling agent in the functional smoking section within the limited range, the faster the stable smoking start-up time, and the smoke concentration is also higher. Examples 1, 4 and 5 show that the more the amount of porous fiber in the functional smoking section within the limited range, the faster the stable smoking start-up time, and the smoke concentration is also higher. Examples 1, 6 and 7 show that the amount of tobacco powder raw material in the solid core within the limited range has little effect on the stable smoking start-up time and smoke concentration. Examples 1, 8 and 9 show that the amount of smoke forming agent in the solid core within the limited range has little effect on the stable smoking start-up time and smoke concentration.

[0117] Comparative Example 1 shows that the bulking agent of the functional smoking segment has a great influence on the stable smoking start-up time and the amount of smoke, and the absence of the bulking agent makes the smoking segment compact, the number of tiny pores between fibers greatly reduced, and the air flow passage blocked. Compared with Comparative Example 10 (a traditional single solid aerosol product), the amount of smoke is slightly increased, but the stable smoking start-up time is longer. Similarly, Comparative Examples 2-4 show that any component in the bulking agent is indispensable, and the absence of any component can accelerate the stable smoking start-up time and the amount of smoke, but the effect is not as good as the combination of the three components.

[0118] Comparative Example 5 shows that the porous fiber of the functional smoking segment also has a great influence on the stable smoking start-up time and the amount of smoke, and the absence of the porous fiber makes the air permeability of the fiber skeleton structure of the smoking segment worse, the air flow passage blocked, and the amount of smoke and the stable smoking start-up time affected. From the effect data analysis, the influence of the porous fiber is slightly less than that of the bulking agent, but is equally important. Comparative Examples 6-7 show that any component in the porous fiber is indispensable, and the absence of any component can accelerate the stable smoking start-up time and the amount of smoke, but the effect is not as good as the combination of the two components.

[0119] Comparative Example 8 shows that the absence of the solid core smoke forming agent has a certain influence on the overall amount of smoke, but has little influence on the stable smoking start-up time, which is mainly due to the greater contribution of the functional smoking segment to the amount of smoke, and the result is caused by the improvement of the smoking efficiency. Test Example 2

[0120] In this test example, the porosity and air permeability of the functional smoking segment of the solid combined aerosol product prepared in Examples 1-5 and Comparative Examples 1-7 are tested, and the test method is as follows:

[0121] (1) Porosity test: gas displacement method is adopted, and the test standard GB / T 10799-2008: "Determination of Open and Closed Cell Volume Percentage of Rigid Foamed Plastics" is selected, and the instrument model is BSD-TD full-automatic true density analyzer;

[0122] (2) Air permeability test: constant pressure difference flow rate method is adopted, and the test standard GB / T 22819-2008 "Determination of Air Permeability of High Air Permeability Paper" is selected, and the instrument model is YN-TQD02 electronic air permeability tester;

[0123] The test results are shown in Table 2. Table 2 Porosity and air permeability data of the functional smoking segment

[0124] As can be seen from Table 2, the porosities of the functional smoking segments in Examples 1-5 are all higher than 50%, and the higher the porosity, the higher the air permeability, which has a positive effect on the improvement of the smoking amount and the smoking efficiency. On the contrary, the porosities of the Comparative Examples are reduced due to the absence of the bulking agent and the porous fiber or the absence of a single component, and the air permeability is low, thereby affecting the smoking effect of the aerosol product. Test Example 3

[0125] In this test example, the solid-state combined aerosol products of Examples 1, 6, 7, and Comparative Example 9 were evaluated and scored, and the specific test was as follows: seven experts of the evaluation committee were invited to evaluate and score the products using a Korean cigarette lil ring-shaped heating smoking device, and the results are shown in Table 3. Table 3 Sensory quality evaluation of solid-state combined aerosol products

[0126] As can be seen from Table 3, the tobacco powder raw material has a greater influence on the strength and aroma of the solid-state combined aerosol product. The strength mainly reflects the physiological satisfaction brought by the tobacco raw material, and the higher the amount of the tobacco raw material, the better the physiological satisfaction. The aroma mainly reflects the aroma components and tobacco experience brought by the tobacco, and the higher the amount of the tobacco raw material, the better the tobacco experience and the more sufficient the aroma. In Comparative Example 9, the absence of the tobacco raw material led to a 57.7% decrease in strength and a 39.4% decrease in aroma (score comparison), and both indicators obviously decreased, which can be seen as the importance of the tobacco powder raw material. Test Example 4

[0127] In this test example, the storage time of the solid-state combined aerosol product prepared in Example 1 and the traditional single solid-state aerosol product prepared in Comparative Example 10 was tested, and the specific test was as follows: the samples were placed in different temperature and humidity environment conditions, and the time points at which phenomena such as leakage, spots, and mold appeared on the surface were recorded, and the results are shown in Table 4. Table 4 Comparison of storage conditions of aerosol products

[0128] As can be seen from Table 4, the storage time of the product of Example 1 in the above environment was 3.4-4.1 times that of the product of Comparative Example 10. Therefore, the solid-state combined aerosol product of the present disclosure has obvious advantages in product quality and stability. Test Example 5

[0129] In this test example, the hardness of the solid-state cores with axial through holes prepared in Examples 8 and 9 and the traditional single solid-state aerosol product prepared in Comparative Example 10 was tested, and the change in hardness after 30 days of storage under different conditions was observed to evaluate the performance and stability of the product in terms of hardness. It should be noted that the hardness test in this test example refers to the determination method of the physical properties of cigarettes, and the specific test equipment is a mu3164 cigarette tester from Shanghai Mowin Industrial Co., Ltd., and the test standard is YC / T 28.6-1996 “Determination of Physical Properties of Cigarettes Part 6: Hardness Point Pressure Method”. The relevant results are shown in Table 5. Table 5 Hardness data of solid-state cores

[0130] As can be seen from Table 5, the content of raw smoke forming agent in the solid core is related to the hardness of the product, wherein the reduction of the smoke forming agent can effectively improve the hardness, and the hardness fluctuation after 30 days is also smaller.

[0131] In summary, the embodiments of the present disclosure effectively solve the problems of low smoke generating efficiency per unit time, low smoke amount, easy to be damp, and poor subsequent processing performance of the traditional solid aerosol product by setting the functional smoking segment and optimizing the formula of the solid core. Not only the smoke generating efficiency and the smoke amount are improved, but also the stability and reliability of the product in the subsequent processing process are improved, which provides an innovative solution for the aerosol product field and has significant practical value.

For those skilled in the art, the present disclosure can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.

The improved aerosol product can be adapted to various exogenous heating appliances such as ring heating, air heating, ring + air, etc. The preparation method of the solid combined aerosol product is simple, and large-scale production can be realized.
