Description

Technical Field

[0001] This application relates to the field of atomized aerosol technology, and in particular to an aerosol generating product and an aerosol generating system. Background Technology

[0002] Aerosol generating products generally produce aerosols through heating without combustion. Specifically, aerosol generating products use an external heat source to heat the aerosol generating matrix in the product to produce aerosols. The aerosol generating matrix does not burn, but instead loads an atomizing agent. When used, the atomizing agent is released by heating to form smoke.

[0003] In related technologies, the efficiency of extracting aerosols through the negative pressure generated during suction is low, and the aerosol generation matrix will deform after heating, which can easily lead to the aerosol generation matrix becoming loose or even falling off, affecting the user's suction experience. Utility Model Content

[0004] In view of this, the embodiments of this application aim to provide an aerosol generating article and an aerosol generating system to improve the user's inhalation experience.

[0005] One embodiment of this application provides an aerosol generating article, including a substrate segment arranged along a first direction and two stop segments, wherein the substrate segment is located between the two stop segments and the substrate segment is used to generate aerosol;

[0006] The aerosol-generated article further includes a coating layer, which covers the outer periphery of the substrate segment and the two stop segments;

[0007] The substrate segment is filled with an aerosol generating substrate, and the filling density of the aerosol generating substrate is 0.1 g / cm3 to 0.6 g / cm3.

[0008] In some embodiments, at least one of the stop sections is provided with an aroma substance.

[0009] In some embodiments, the two stop sections are made of the same or different materials; and / or, the two stop sections have the same or different structures.

[0010] In some embodiments, at least one of the stop sections is: a membrane structure with air permeability, a solid fiber structure, a hollow tubular structure, a structure formed by setting a separator in a hollow tubular structure, or a solid porous molecular sieve structure.

[0011] In some implementations, the suction resistance of any one of the stop sections does not exceed 15 Pa / mm.

[0012] In some embodiments, the substrate segment and the two stop segments are cylinders with the same outer diameter and coaxially arranged.

[0013] In some embodiments, the aerosol-generating article has a dimension of 10 mm to 85 mm along the first direction; and / or, the cross-sectional shape of the aerosol-generating article is circular, and the outer diameter of the aerosol-generating article is 4 mm to 12 mm.

[0014] In some embodiments, the sum of the dimensions of the two stop segments in the first direction is not less than 10% of the dimension of the aerosol-generating article along the first direction.

[0015] In some embodiments, the dimension of any one of the stop segments along the first direction is 3mm to 20mm.

[0016] In some implementations, the difference in size between the two stop segments along the first direction is 0 mm to 10 mm.

[0017] This application provides an aerosol generation system according to a second embodiment, comprising:

[0018] The aerosol generating device has a containment space;

[0019] And the aerosol generating article described in any of the above embodiments, wherein the accommodating space is at least used to accommodate the substrate segment of the aerosol generating article;

[0020] The aerosol generating device includes a filter nozzle and a heating element. The filter nozzle connects the receiving space and the external space. The heating element heats the substrate segment contained in the receiving space.

[0021] In some embodiments, the aerosol-generating article is interchangeably inserted into the receiving space at both ends in the first direction.

[0022] In some embodiments, at least one of the two stop sections has a clearance channel into which at least a portion of the heating element is inserted to heat the substrate section.

[0023] The aerosol generating article and aerosol generating system of this application limit the filling density of tobacco particles in the substrate segment, keeping the draw resistance of the substrate segment within a reasonable range. This prevents the filled tobacco particles from excessively increasing the overall draw resistance of the aerosol generating article, facilitating aerosol extraction by the user and improving the user experience. Furthermore, the two stop segments are located at both ends of the substrate segment along the first direction. This aerosol generating article lacks components such as support segments, cooling segments, and filter segments, resulting in a simple structure that is easy to manufacture. The two stop segments also effectively stop the substrate segment, significantly reducing the possibility of shrinkage and deformation leading to detachment after heating.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0032] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this application will not be described separately.

[0033] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0034] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0035] This application provides an aerosol-generating article 10, please refer to... Figure 1 and Figure 2 The aerosol-generating article 10 includes a substrate segment 11 arranged along a first direction and two stop segments 12, with the substrate segment 11 located between the two stop segments 12.

[0036] It should be noted that the first direction refers to Figure 1 The direction indicated by the middle arrow.

[0037] The aerosol-generating article 10 also includes a coating layer 13, which covers the outer periphery of the substrate segment 11 and the two stop segments 12. It is understood that the coating layer 13 can connect the substrate segment 11 and the two stop segments 12, thereby improving the overall stability of the aerosol-generating article 10.

[0038] The material of the covering layer 13 is not limited. For example, the covering layer 13 includes, but is not limited to, one or more of the following materials: fiber paper, metal foil, metal foil composite fiber paper, polyethylene composite fiber paper, PE (polyethylene), PBAT (butylene adipate-co-terephthalate).

[0039] The substrate segment 11 is used to generate aerosols. For example, the substrate segment 11 releases aerosols when heated.

[0040] The substrate segment 11 is filled with an aerosol-generating substrate, and the packing density (abbreviated as p) of the aerosol-generating substrate is 0.1 g / cm³. 3 ~0.6g / cm 3 That is, 0.1 g / cm³ 3 ≤p≤0.6g / cm 3 For example, p can be 0.1 g / cm³. 3 0.2g / cm 3 0.3g / cm 3 0.4g / cm 3 0.5g / cm 3 0.6g / cm 3 Understandably, the reasonable filling density of the aerosol generating substrate allows the substrate segment 11 to generate sufficient aerosols while also ensuring good airflow permeability, facilitating aerosol extraction for users and thus improving their user experience.

[0041] It should be noted that the filling density refers to the bulk density, which is the ratio of mass to total volume. The total volume refers to the sum of the solid volume of the filling material in the substrate segment 11 and the volume of the pores between the filling materials.

[0042] In some embodiments, 0.3 g / cm 3 ≤p≤0.5g / cm 3 This improves the airflow permeability of the substrate section 11, making it easier for users to extract aerosols.

[0043] It should be noted that the aerosol generating substrate can be a filamentous, sheet-like, strip-like, granular, or extruded cylindrical material made from one or more of tobacco leaves, tobacco leaf fragments, tobacco stems, tobacco dust, reconstituted tobacco leaves, or other herbaceous plants.

[0044] In related technologies, in order to enable users to extract as much aerosol as possible during the inhalation process, the filling density of tobacco particles in the substrate segment is increased, which leads to an increase in the draw resistance of the substrate segment, making it more difficult for users to inhale and thus reducing the user experience.

[0045] The aerosol generating article 10 of this application embodiment limits the filling density of tobacco particles in the substrate segment 11, so that the draw resistance of the substrate segment 11 can be kept within a reasonable range. This prevents the filled tobacco particles from excessively increasing the overall draw resistance of the aerosol generating article 10, making it easier for users to extract aerosols by inhalation and improving the user experience.

[0046] Furthermore, in some related technologies, aerosol generating products generally have four or more components, such as a matrix section, a support section, a cooling section, and a filtration section. This makes the manufacturing process complex, and the aerosol generating matrix section shrinks and deforms after heating, making it prone to loosening or even detachment during suction. In contrast, the aerosol generating product 10 provided in this application has two stop sections 12 located at both ends of the substrate section 11 along the first direction. This aerosol generating product 10 lacks components such as a support section, a cooling section, and a filtration section, resulting in a simple structure that is easy to manufacture. Moreover, the two stop sections 12 effectively stop the substrate section 11, significantly reducing the possibility of it shrinking and deforming after heating and detaching.

[0047] The specific composition of the substrate segment 11 is not limited here. For example, in one embodiment, the substrate segment 11 may also include plant ingredients, smoke-generating agent ingredients, etc.

[0048] The function of the smoke-generating agent is to produce a large amount of vapor upon heating, thereby increasing the amount of smoke in the smoke-generating product. In one embodiment, the smoke-generating agent may include, for example, one or more combinations of: a monohydric alcohol (such as menthol); a polyhydric alcohol (such as propylene glycol, triethylene glycol, 1,3-butanediol, and glycerol); an ester of a polyhydric alcohol (such as glyceryl monoacetate, glyceryl diacetate, or glyceryl triacetate); a monocarboxylic acid; a polycarboxylic acid (such as lauric acid, myristic acid) or an aliphatic ester of a polycarboxylic acid (such as dimethyl dodecanoate, dimethyl tetradecanoate, erythritol, 1,3-butanediol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl lauryl acetate, triacetin, meso-erythritol, a mixture of diacetins, diethyl caprylate, triethyl citrate, methyl benzoate, phenylacetic acid methyl ester, ethyl vanillate, glyceryl tributate, and lauryl acetate).

[0049] For example, the weight of the smoke-generating agent component in the substrate segment 11 accounts for no less than 10% of the total weight of the substrate segment 11. This ensures that the aerosol generated by the substrate segment 11 has a reasonable amount of smoke.

[0050] For example, the substrate segment 11 may be a filamentous structure, a sheet-like structure, a granular structure, or a monolithic structure.

[0051] One embodiment of this application provides an aerosol generation system 1, please refer to... Figure 1 The aerosol generation system 1 includes an aerosol generation device 20 and an aerosol generation article 10 according to any embodiment.

[0052] The aerosol generating apparatus 20 has a receiving space 20a, which is at least used to accommodate the substrate segment 11 of the aerosol generating article 10.

[0053] The aerosol generating device 20 includes a filter 21 and a heating element 22. The filter 21 connects the receiving space 20a and the external space. The heating element 22 heats the substrate segment 11 housed in the receiving space 20a. It is understood that the heat generated by the heating element 22 can heat and atomize the substrate segment 11. During suction, the aerosol generated by the heated substrate segment 11 can enter the user's mouth through the filter 21.

[0054] Furthermore, the shape of the substrate segment 11 is not limited; for example, please refer to [reference needed]. Figure 1 The substrate segment 11 can be columnar. The cross-sectional shape of the columnar substrate segment 11 can be circular or other shapes, such as polygons (including but not limited to triangles, squares, rhombuses, etc.), ellipses, racetracks, or irregular shapes. Irregular shapes refer to other symmetrical or asymmetrical shapes other than those listed above.

[0055] In some embodiments, please refer to Figure 1 The substrate segment 11 and the two stop segments 12 are cylinders with the same outer diameter and coaxially arranged. In this way, the uniformity of the contour of the aerosol-generated article 10 along the first direction can be improved. On the one hand, it can improve the cleanliness of the appearance surface of the aerosol-generated article 10. On the other hand, it can facilitate the coating layer 13 to better cover the substrate segment 11 and the two stop segments 12, reducing the manufacturing difficulty of the aerosol-generated article 10.

[0056] In some embodiments, please refer to Figure 3 and Figure 4 At least one stop section 12 contains an aromatic substance. This enriches the aroma of the aerosol and enhances the user's inhalation experience.

[0057] For ease of description, the two stop sections 12 can be referred to as the first stop section 12' and the second stop section 12, respectively.

[0058] It should be noted that the above-mentioned aroma substances are provided in the following ways: firstly, the aroma substance is provided in the first stop section 12'; secondly, the aroma substance is provided in the second stop section 12"; and thirdly, the aroma substance is provided in both stop sections 12".

[0059] It should be noted that in embodiments where aroma substances are provided in both stop sections 12, the aroma substances of each of the two stop sections 12 are not limited in their fragrance. They can be the same fragrance, such as both being mint; or they can be different fragrances, such as one being mint and the other being blueberry.

[0060] It should be noted that the specific structure carrying the aroma substance is not limited; for example, the structure carrying the aroma substance can be as follows: Figure 4 The fragrance line structure 12a shown can also be as follows: Figure 3The fragrance bead structure 12b is shown.

[0061] In some embodiments, the two stop segments 12 may be made of the same or different materials. That is, the two stop segments 12 may be made of the same material or different materials.

[0062] For example, at least one stop section 12 is one of the following: a membrane structure with air permeability, a solid fiber structure, a hollow tubular structure, a structure formed after setting a separator in a hollow tubular structure, or a solid porous molecular sieve structure.

[0063] Breathable membrane structures refer to structures such as breathable paper and breathable membranes that have good breathability, allowing airflow to pass through more smoothly.

[0064] Hollow tubular structures refer to tubular structures with hollow channels, such as PET tubes, cellulose acetate tubes, silicone tubes, paper tubes, etc. The hollow channels are for airflow.

[0065] The structure formed after setting a separator in the hollow tubular structure refers to the following: the stop section 12 may include a tube with a hollow channel and a separator set in the hollow channel. The separator divides the hollow channel into multiple air passages. In other words, the hollow channel can be further divided into multiple air passages, and the airflow can pass through different air passages respectively.

[0066] A solid fiber structure refers to a structure primarily composed of fibers, with airflow passing through naturally formed pores between the fibers. Solid fiber structures do not have macroscopic air channels. Macroscopic air channels refer to airflow passages mainly formed through processing (such as the air channels described in the previous examples). The cross-sectional area and length of the air channels can be changed according to design requirements, while the cross-sectional area and length of the pores between the fibers are mainly formed naturally during processing.

[0067] The material of a solid porous molecular sieve structure is a porous molecular sieve, which is a porous crystal. Porous molecular sieves have a large number of naturally formed channels with relatively uniform pore sizes. Moreover, these channels generally only allow molecules smaller than their pore size to enter. Therefore, porous molecular sieves can be used to sieve molecules in a substance according to their size.

[0068] The solid porous molecular sieve structure also does not have macroscopic gas channels.

[0069] For example, the two stop sections 12 may have the same or different structures. Depending on different design requirements, the two stop sections 12 may have the same or different structures. For example, one of the two stop sections 12 may be a hollow tubular structure, while the other stop section 12 may be a solid fiber structure or a solid porous molecular sieve structure.

[0070] In some embodiments, the suction resistance of any one of the stop sections 12 does not exceed 15 Pa / mm. It is understood that the suction resistance of both stop sections 12 does not exceed 15 Pa / mm, which makes the suction resistance of the stop sections 12 reasonable, allowing the external airflow to pass smoothly through the stop sections 12, reducing the difficulty of suction for the user, and improving the suction experience of the aerosol generating product 10.

[0071] For example, the two stop sections 12 have different suction resistances. For instance, the first stop section 12' is the stop section 12 located at the first end of the substrate section 11 along the first direction, and the second stop section 12" is the stop section 12 located at the second end of the substrate section 11 along the first direction. Since the first stop section 12' needs to allow external airflow to smoothly enter the substrate section 11 while providing a stop, its suction resistance can be relatively small. On the other hand, the second stop section 12" can be used to increase the suction resistance of the aerosol-generating article 10 to prevent suction voids, so its suction resistance can be relatively large. For example, the suction resistance of the first stop section 12' is 6 Pa / mm, and the suction resistance of the second stop section 12" is 12 Pa / mm.

[0072] In some embodiments, please refer to Figure 2 The aerosol generating article 10 has a dimension D1 of 10 mm to 85 mm along the first direction; and / or, the cross-sectional shape of the aerosol generating article 10 is circular, and the outer diameter of the aerosol generating article 10 is 4 mm to 12 mm. It is understood that making the dimensions of the aerosol generating article 10 reasonable facilitates both its manufacture and its insertion into the aerosol generating apparatus 20.

[0073] In some embodiments, please refer to Figure 2 The ratio of the sum of the dimensions of the two stop segments 12 in the first direction (D2+D3) to the dimension D1 of the aerosol generating article 10 in the first direction is not less than 10%, i.e., 10% ≤ (D2+D3) / D1 < 100%. For example, the ratio of the sum of the dimensions of the two stop segments 12 in the first direction to the dimension of the aerosol generating article 10 in the first direction can be: 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%. This ensures that the ratio of the dimensions of the two stop segments 12 to the aerosol generating article 10 is reasonable, which can ensure that the two stop segments 12 can provide a reliable stopping function for the substrate segment 11 without occupying too much space of the substrate segment 11, and can ensure that the user can draw in sufficient aerosol.

[0074] For example, please refer to Figure 2The ratio of the sum of the dimensions of the two stop segments 12 in the first direction (D2+D3) to the dimension D1 of the aerosol generating article 10 in the first direction is 20% to 70%. That is, (D2+D3) / D1 = 20% to 70%. For example, the ratio of the sum of the dimensions of the two stop segments 12 in the first direction to the dimension of the aerosol generating article 10 in the first direction can be: 20%, 30%, 40%, 50%, 60%, or 70%.

[0075] In some embodiments, please refer to Figure 2 The dimensions (D2, D3) of any stop segment 12 along the first direction are 3mm to 20mm, i.e., 3mm≤D2≤20mm and 3mm≤D3≤20mm. For example, D2 can be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 12mm, 14mm, 16mm, 18mm, or 20mm, and D3 can be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 12mm, 14mm, 16mm, 18mm, or 20mm. This ensures that the dimensions of the stop segment 12 along the first direction are reasonable, providing sufficient structural strength to stop the base material segment 11 while also ensuring reasonable suction resistance, thus guaranteeing a good user experience during suction.

[0076] For example, the difference in size between the two stop segments 12 along the first direction ranges from 0mm to 10mm, i.e., 0mm ≤ |D2-D3| ≤ 10mm, meaning the difference is an absolute value. In other words, the two stop segments 12 do not have a significant difference in size along the first direction, facilitating manufacturing.

[0077] For example, the difference in size between the two stop segments 12 along the first direction does not exceed 7mm, i.e., 0mm≤|D2-D3|≤7mm.

[0078] In some embodiments, please refer to Figure 2 The aerosol-generating article 10 can be inserted into the receiving space interchangeably at both ends in the first direction.

[0079] In other words, any one of the stop sections 12 can be located on the side of the substrate section 11 closest to the filter tip 21.

[0080] It is understandable that either of the two stop segments 12 can be located at the first end of the substrate segment 11 along the first direction, and either of the two stop segments 12 can be located at the second end of the substrate segment 11 along the first direction. This means that during the process of inserting the aerosol generating article 10 into the aerosol generating device 20, it is not necessary to distinguish the insertion direction of the aerosol generating article 10, and either end of the aerosol generating article 10 along the first direction can be used as the insertion end for inserting into the aerosol generating device 20.

[0081] To facilitate the interchangeability of the two ends of the aerosol-generated product 10, the two stop sections 12 can be made of materials with the same or similar performance parameters.

[0082] For example, please refer to Figure 1 The aerosol generating apparatus 20 also includes a power source 23, which can supply electricity to operate the aerosol generating apparatus 20. For example, the power source 23 can supply electricity so that the heating element 22 can heat the aerosol generating article 10.

[0083] In some embodiments, please refer to Figure 5 At least one of the two stop sections 12 has a clearance channel 12c, and at least a portion of the heating element 22 is inserted into the clearance channel 12c to heat the substrate section 11. Thus, a portion of the heating element 22 can be inserted into the interior of the aerosol generating article 10 through the clearance channel 12c, while a portion of the heating element 22 is located on the exterior of the aerosol generating article 10. By baking and heating the aerosol generating article 10 from the inside out, the substrate section 11 can be heated uniformly, thereby improving the uniformity of the aerosol generated by the substrate section 11 and thus enhancing the user experience.

Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Furthermore, without contradiction, those skilled in the art can combine different embodiments or examples described in this application, as well as features of different embodiments or examples.
