[0039] The aerosol generating article provided by the present application can be placed in the accommodating cavity of the aerosol generating device, and only the smoking segment 10 can be placed in the accommodating cavity, and then the smoking segment 10 can be heated by the above-mentioned accommodating cavity to generate aerosol through hot air flow or circumferential heating, so as to realize the smoking effect.
[0040] In the embodiments of the present application, the smoking segment 10 is solid, the smoking matrix 11 as the main part of the smoking segment 10 has a water content of 0-5%, which can directly generate aerosol with fragrance under heating conditions, avoiding the problem of prominent paste taste in aerosol caused by direct heating on the wrapping piece in the circumferential heating mode.
[0041] In the embodiments of the present application, the smoking matrix is formed by mixing and pressing tobacco powder, second flavor, smoking agent, filler and adhesive, and the water content of the mixture after mixing is not more than 5%, which can effectively ensure the processing strength of the smoking matrix. The appropriate moisture content in the mixed mixture can also reduce the molding difficulty, ensure that the smoking segment 10 has certain loose and breathable properties, and also ensure a certain amount of smoke.
[0042] In some embodiments, the second flavor and the smoking agent account for 30-50% of the mass percentage of the smoking segment, which can ensure the smoke amount and fragrance amount on the premise of ensuring the processing strength.
[0043] In addition, in some embodiments, the smoking matrix 11 includes 20-30 parts of tobacco powder, 10-20 parts of second flavor, 20-30 parts of smoking agent, 10-20 parts of filler and 10-20 parts of adhesive, which can ensure the smoke amount and fragrance amount on the premise of ensuring the processing strength.
[0044] In addition, in some embodiments, the particle size of the tobacco powder, the filler and the adhesive is 30-100 mesh, for example, one of 30 mesh, 40 mesh, 50 mesh, 80 mesh and 100 mesh or a range value of any two thereof.
[0045] In addition, in some embodiments, the second flavor includes at least one of monomer synthetic flavor, natural flavor raw material, fragrance base and essence;

[0047] In addition, in some embodiments, the filler includes at least one of anhydrous lactose and microcrystalline cellulose. The weight and volume of the smoking segment 10 are filled to make the smoking matrix 11 easy to be molded.
[0048] In addition, in some embodiments, the adhesive includes at least one of carboxymethyl cellulose and dextrin, which can bond each powder raw material into a solid, and also can increase stability to prevent oxidation or decomposition; in addition, the joint action of the filler and the adhesive makes the smoking segment 10 have better moisture-proof effect.
[0049] In the embodiment of the present application, the through hole 12 is arranged in the smoking segment 10 of the aerosol generating article, so that when the aerosol generating article is placed in the accommodating cavity of the aerosol generating device, the through hole 12 can be in communication with the accommodating cavity and the suction end of the aerosol generating article at the same time, and the essence and spices in the smoking segment 10 and the through hole 12 can be slowly and uniformly released, so that the smoking amount and the aroma amount are persistent and stable, thereby effectively solving the problem that the addition amount of the smoking agent and the essence and spices is limited due to the processing strength of the existing solid smoking segment 10, resulting in insufficient aroma amount and non-persistent aroma.
[0050] When the user sucks the aerosol generating article, the through hole 12 will have a negative pressure, so that the aerosol generated by the smoking segment 10 penetrates into the through hole 12, thereby ensuring the stability of the smoking amount and the aroma amount; at the same time, the negative pressure formed in the through hole 12 also causes the gas to flow into the through hole 12, and the gas contacts the smoking segment 10, thereby increasing the oxygen content in the aerosol generating article and helping to improve the smoking rate of the aerosol generating article.
[0051] In addition, in the embodiment of the present application, the extension direction of the through hole 12 is consistent with the suction direction of the aerosol generated by the smoking segment 10, so as to form a negative pressure in the through hole 12, thereby making the aerosol suction path smooth, and thereby smoothly sucking the aerosol to the suction end.
[0052] In the aerosol generating article provided in the embodiment of the present application, the above-mentioned through hole 12 can be arranged only one in the smoking matrix 11, as shown in Figures 1-3 、 Figures 7-8 、 Figures 11-12 The above-mentioned through hole 12 can also be arranged in parallel in the smoking matrix 11, for example, two, three, four, five or six, as shown in Figures 4-6 、 Figures 9-10 、 Figures 13-14 so that the gas can be more fully contacted with the smoking segment 10, thereby helping to improve the smoking rate of the aerosol generating article.
[0053] In addition, in some embodiments, a plurality of the above-mentioned through holes 12 are arranged through the smoking matrix 11, and the hole diameters of each of the above-mentioned through holes 12 are the same, so that the gas flow intensity of each gas channel is consistent, and thereby the aerosol generated by the smoking segment 10 is more uniform and stable.
[0054] In addition, in some embodiments, a plurality of the above-mentioned through holes 12 are uniformly distributed along the cross section of the smoking segment 10 perpendicular to the aerosol flow direction, and the gas flow intensity of each region of the smoking segment 10 along the cross section of the smoking segment perpendicular to the aerosol flow direction tends to be consistent, which can better improve the uniformity and stability of the aerosol generated by the smoking segment 10.
[0055] In addition, in some embodiments, the plurality of holes 12 are arranged in a central symmetric manner along the cross section of the smoking segment perpendicular to the direction of the aerosol flow, which can further improve the uniformity and stability of the aerosol generated by the smoking segment 10.
[0056] In addition, in some embodiments, the cross section of the hole can be a regular or irregular polygon, which can be a circle, a triangle, a quadrilateral, a pentagon, a pentagram, or the like.
[0057] In addition, in some embodiments, the distance between the edge of the hole and the edge of the smoking segment substrate is greater than or equal to 1 mm, and the distance between adjacent holes is greater than or equal to 0.5 mm, so as to ensure that the smoking segment substrate has sufficient structural strength.
[0058] In addition, in some embodiments, a plurality of holes 12 are arranged through the smoking substrate 11, and at least one of the holes is not filled with the flavoring filler. That is, in the embodiments of the present application, among the plurality of holes 12 arranged through the smoking substrate 11, at least one hole 12 is filled with the flavoring filler 13, and at least one hole 12 is kept as a gas permeable hole. On the premise of ensuring the normal flow of the gas flow, the flavoring filler 13 filled in the hole 12 can continuously release the fragrance, thereby effectively solving the problem that the amount of fragrance is insufficient and the fragrance is not long-lasting due to the limitation of the amount of smoking agent and flavoring agent added in the existing solid smoking segment 10.
[0059] In some embodiments, the resistance of the hole filled with the flavoring filler is less than or equal to 4000 Pa, for example, it can be one of 500 Pa, 1000 Pa, 1500 Pa, 1800 Pa, 2000 Pa, 3000 Pa, 4000 Pa or a range value of any two of them. Not only can it ensure the normal flow of the gas flow and the amount of aerosol generated by the aerosol product, but also the flavoring filler 13 filled in the hole 12 can continuously release the fragrance, thereby effectively solving the problem that the amount of fragrance is insufficient and the fragrance is not long-lasting due to the limitation of the amount of smoking agent and flavoring agent added in the existing solid smoking segment 10.
[0060] In addition, in some embodiments, a plurality of holes 12 are arranged through the smoking substrate 11, and at least one of the holes 12 is hollow, and the remaining holes 12 are filled with the flavoring filler 13. That is, in the embodiments of the present application, among the plurality of holes 12 arranged through the smoking substrate 11, at least one hole 12 is kept in a hollow or cavity state as an air flow channel, and the other holes 12 are filled with the flavoring filler 13. Not only can it ensure the normal flow of the gas flow and the amount of aerosol generated by the aerosol product, but also the flavoring filler 13 filled in the hole 12 can continuously release the fragrance, thereby effectively solving the problem that the amount of fragrance is insufficient and the fragrance is not long-lasting due to the limitation of the amount of smoking agent and flavoring agent added in the existing solid smoking segment 10.
[0061] In addition, in some embodiments, a plurality of the above-mentioned channels 12 are arranged through the smoking substrate 11, and the smoking substrate is a loose porous body. That is, in the embodiments of the present application, the smoking substrate itself is a loose porous body, which can be used as an air flow channel to ensure the normal flow of air and the amount of smoke of the aerosol generating article, and the plurality of channels 12 arranged through the smoking substrate 11 are filled with the flavor filling 13, which can continuously release the fragrance, thereby effectively solving the problem of insufficient and short-lasting fragrance caused by the limited addition of smoking agents and flavoring agents in the existing solid smoking segment 10 due to the processing strength.
[0062] In some embodiments, the above-mentioned flavor filling includes a flavor carrier and a first flavoring agent combined with the flavor carrier.
[0063] In addition, in some embodiments, the above-mentioned flavor carrier 13 includes, but is not limited to, one or more of activated carbon, diatomite, molecular sieve, and porous polymer, which can absorb fragrance and slowly and uniformly release it, and has a good adsorption effect on low ester fragrance substances such as furanone, menthol, and ethyl maltol.
[0064] In some embodiments, the above-mentioned flavor carrier 13 includes, but is not limited to, one or more of activated carbon, diatomite, molecular sieve, and porous polymer, which can absorb fragrance and slowly and uniformly release it, and has a good adsorption effect on low ester fragrance substances such as furanone, menthol, and ethyl maltol.
[0065] In addition, in some embodiments, the flavor filling 13 filled in each of the above-mentioned channels 12 accounts for 10-20% of the mass percentage of the smoking substrate 11, for example, one of 10%, 12%, 15%, 18%, and 20% or a range value of any two thereof, which can increase the loading amount of flavoring agents and improve the amount and duration of fragrance on the premise of ensuring the overall structural strength of the smoking segment.
[0066] In the embodiments of the present application, the shape of the above-mentioned smoking segment 10 can match the accommodating cavity of the aerosol generating device accommodating the aerosol generating article, and the overall shape can be a tubular shape as shown in Figures 1-6 , an ellipsoidal shape as shown in Figures 7-10 , or a spherical shape as shown in Figures 11-14 .
[0067] The embodiments of the present application also provide a manufacturing method of a smoking segment, as shown in Figure 15 , which includes steps 101-103:
[0068] Step 101, uniformly mixing tobacco powder, smoking flavoring substances, smoking agents, fillers, and binders to obtain a smoking substrate;
[0069] Step 102, stamping the smoking substrate into a smoking substrate with one or more channels;
[0070] Step 103, filling the at least one channel with a flavoring filler to obtain a smoking segment.
[0071] In the embodiments of the present application, after the tobacco powder, the tobacco flavoring substance, the smoking agent, the filler and the binder are uniformly mixed, a smoking matrix having one or more channels is directly prepared by using a compression molding method, and then a flavoring filler is filled into the at least one channel to obtain a smoking segment.
[0072] The compression molding method makes the smoking segment have various forms, has low loss in the manufacturing process, and has a simple manufacturing method, which is suitable for enterprises to develop differentiated products. The shape of the smoking segment can be matched with the accommodation cavity of the aerosol-generating device that accommodates the aerosol-generating article. For example, the overall shape of the smoking segment can be a tube shape as shown in FIG. 1A, an ellipsoidal shape as shown in FIG. 1B, or a spherical shape as shown in FIG. 1C. Figures 1-6 Figures 7-10 Figures 11-14
[0073] Meanwhile, the channel is formed by compression molding, and mechanical punching or grooving is not required on the smoking segment. The channel of the smoking segment is filled with a flavoring filler, so that when the aerosol-generating article is placed in the accommodation cavity of the aerosol-generating device, the channel can be in communication with the accommodation cavity and the suction end of the aerosol-generating article at the same time. This not only allows the flavoring in the smoking segment to be slowly and uniformly released, so that the amount of smoke and the amount of aroma are stable, thereby improving the smoking quality, but also allows the flavoring filler in the channel to be continuously released, thereby effectively solving the problem that the amount of aroma is insufficient and the aroma is not long-lasting due to the limited addition amount of the smoking agent and the flavoring in the existing solid smoking segment.
[0074] Specifically, when a user smokes the aerosol-generating article, a negative pressure is generated in the channel, so that the aerosol generated by the smoking segment penetrates into the channel, thereby ensuring the stability of the amount of smoke and the amount of aroma. At the same time, the negative pressure formed in the channel also causes gas to flow into the channel, and the gas contacts the smoking segment, thereby increasing the oxygen content in the aerosol-generating article and helping to improve the smoking rate of the aerosol-generating article.
[0075] In addition, in the embodiments of the present application, the extension direction of the channel is consistent with the suction direction of the aerosol generated by the smoking segment, so as to form a negative pressure in the channel, thereby ensuring smoothness of the aerosol gas path during suction, and thereby smoothly sucking the aerosol to the suction end.
[0076] In addition, the solid smoking segment provided by the present application does not need to be baked after tabletting, thereby avoiding serious volatilization of the added flavoring and smoking agent, and reducing the loss of volatile components.
[0077] In the aerosol generating article provided by the embodiments of the present application, the above-mentioned hole can be arranged only one in the smoking substrate, or can be arranged in parallel in the smoking substrate, for example, two, three, four, five or six, so that the gas can be in more sufficient contact with the smoking segment, which helps to improve the smoking rate of the aerosol generating article.
[0078] In addition, in some embodiments, a plurality of the above-mentioned holes are arranged through the smoking substrate, the hole diameters of each of the above-mentioned holes are the same, so that the airflow intensity of each gas channel is consistent, and further, the aerosol generated by the smoking segment is more uniform and stable.
[0079] In addition, in some embodiments, the plurality of the above-mentioned holes are uniformly distributed along the cross section of the smoking segment perpendicular to the aerosol flow direction, and the airflow intensity of each area of the smoking segment along the cross section of the smoking segment perpendicular to the aerosol flow direction tends to be consistent, which can better improve the uniformity and stability of the aerosol generated by the smoking segment.
[0080] In addition, in some embodiments, the plurality of the above-mentioned holes are centrally symmetrically distributed along the cross section of the smoking segment perpendicular to the aerosol flow direction, which can further improve the uniformity and stability of the aerosol generated by the smoking segment.
[0081] In the manufacturing method provided by the embodiments of the present application, the addition amount of the smoking agent and the flavoring agent is not limited, and under the same weight, the total amount of the smoking agent and the flavoring agent added in the prepared smoking segment can be increased to more than twice that of the smoking segment prepared by the prior art, which can effectively solve the problem of insufficient addition amount of the smoking agent and the flavoring agent in the existing smoking segment due to the limitation of processing strength.
[0082] In some embodiments, the above-mentioned step 101 comprises:
[0083] The tobacco powder, the second flavoring agent, the smoking agent, the filler and the binder are uniformly mixed according to the mass ratio of (20-30):(10-20):(20-30):(10-20):(10-20).
[0084] By uniformly mixing the tobacco powder, the second flavoring agent, the smoking agent, the filler and the binder according to the mass ratio of (20-30):(10-20):(20-30):(10-20):(10-20), and controlling the water content to be 0-5%, the obtained smoking segment substrate material not only facilitates direct molding by molding, but also ensures the smoking amount and the flavor amount under the premise of ensuring the processing strength.
[0085] In addition, in some embodiments, the particle size of the tobacco powder, the filler and the binder is 30-100 mesh, for example, one of 30 mesh, 40 mesh, 50 mesh, 80 mesh, 100 mesh or a range value of any two thereof. The tobacco powder, the filler and the binder are graded within the above particle size range, so that the obtained smoking segment substrate is not only suitable for mold forming, but also effectively balances the processing strength and the smoking rate.
[0086] In the embodiments of the present application, the tobacco powder, the second flavoring agent, the smoking agent, the filler and the binder can be directly mixed uniformly according to the above mass ratio, or the tobacco powder, the filler and the binder can be first mixed uniformly according to the above mass ratio, and then the tobacco flavoring agent, the smoking agent, the filler and the binder are added.
[0087] In addition, in some embodiments, the pressure of the stamping process is 10-40 kN, for example, one of 10 kN, 15 kN, 20 kN, 30 kN, 40 kN or a range value of any two thereof, so that the prepared smoking segment has the advantages of loose texture, low relative density, light weight, good adsorption effect, etc.
[0088] In addition, in some embodiments, the second flavoring agent includes at least one of a monomer synthetic flavoring agent, a natural flavoring raw material, a fragrance base and a fragrance essence.
[0089] In addition, in some embodiments, the smoking agent includes at least one of propylene glycol and glycerol.
[0090] In addition, in some embodiments, the filler includes at least one of anhydrous lactose and microcrystalline cellulose. The weight and volume of the smoking segment are filled, so that the above smoking substrate is easy to mold.
[0091] In addition, in some embodiments, the binder includes at least one of carboxymethyl cellulose and dextrin, which can bond the powder raw materials into a solid, and also can increase the stability to prevent oxidation or decomposition. In addition, the joint action of the filler and the binder makes the smoking segment have better moisture-proof effect.
[0092] In some embodiments, the flavoring filler includes a fragrance-carrying part and a first flavoring agent combined with the fragrance-carrying part.
[0093] In addition, in some embodiments, the fragrance-carrying part 13 includes but is not limited to one or more of activated carbon, diatomite, molecular sieve and porous polymer, which can absorb fragrance and slowly and uniformly release, and has a good adsorption effect on low ester flavoring agents such as furanone, menthol, ethyl maltol, etc.
[0094] The first flavoring agent includes one or more of furanone, menthol and ethyl maltol.
[0095] In addition, in some embodiments, the aroma filler 13 filled in each of the above-mentioned holes 12 accounts for 10-20% of the mass percentage of the smoke emitting base 11, for example, one of 10%, 12%, 15%, 18%, 20% or a range value of any two thereof, which can increase the load of the essence flavor, improve the amount of aroma and the duration of aroma on the premise of ensuring the overall structural strength of the smoke emitting segment
[0096] In addition, in some embodiments, the aroma filler 13 filled in each of the above-mentioned holes 12 accounts for 10-20% of the mass percentage of the smoke emitting base 11, for example, one of 10%, 12%, 15%, 18%, 20% or a range value of any two thereof, which can increase the load of the essence flavor, improve the amount of aroma and the duration of aroma on the premise of ensuring the overall structural strength of the smoke emitting segment

[0132] The embodiments of the present application provide an aerosol generating system 100, such as Figure 16 , comprising an aerosol generating device 20, and an aerosol generating article 10 according to any one of the above embodiments;
[0133] The aerosol generating article 10 is used to be mounted inside a containing cavity 21 of the aerosol generating device 20 and is completely contained in the containing cavity 21, and is heated by the aerosol generating device 20.
[0134] In the embodiments of the present application, the aerosol generating article only has a bare smoking segment, without filter and cigarette paper wrapping, and the aerosol generating device 20 includes a suction nozzle 30 communicating with the outlet of the accommodating cavity 21, so that the user can suck the aerosol flowing out of the accommodating cavity 21 through the suction nozzle 30. Since the smoking segment is located inside the accommodating cavity, only the smoking segment is heated when the aerosol generating article is heated, so there is no paper taste. Since the smoking segment is provided with the hole penetrating through at least one end surface along the aerosol flow direction in the aerosol generating article, the hole can be in communication with the accommodating cavity and the suction end of the aerosol generating article at the same time once the aerosol generating article is placed in the accommodating cavity of the aerosol generating device, so that the essence and spices in the smoking segment can be slowly and uniformly released, the amount of smoke and the amount of aroma are stable, and thus the smoking quality is improved.
[0135] In addition, in other embodiments, the aerosol generating article can also include a filter segment connected with the smoking segment.
