Description

Smoke generator, cartridges and e-cigarettes

[0001] This application claims priority to Chinese Patent Application No. 202510107100.2, filed on January 22, 2025, with the China National Intellectual Property Administration; and to Chinese Patent Application Nos. 202610030991.0, 202610033713.0, 202610033552.5, and 202610032803.8, filed on January 9, 2026, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application mainly relates to the field of smoke generator technology based on aerosol matrix, and particularly to a smoke generator, a cartridge, and an electronic cigarette. Background Technology

[0003] In related technologies, a carrier substrate supporting an aerosol matrix is ​​usually tightly bonded to a heating element used to heat the substrate. The temperature field generated by the heating element heats and carbonizes the carrier substrate, thereby generating an aerosol. Technical issues

[0004] However, in the prior art, the heating elements are generally arranged in a concentrated manner. The temperature field formed by the concentrated arrangement of heating elements has an obvious temperature gradient, which causes the carbonization degree of the substrate to be uneven with different positions. At the same time, it causes the aerosol release to be unstable over time, which is manifested as the decrease in the amount of aerosol generated between different numbers of suction ports. Technical solutions

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0036] The electronic cigarette of this application (not shown in the figure) is a heat-not-burn type aerosol generation system, which includes a cartridge 10 and a device for heating the cartridge 10.

[0037] In the embodiments of this application, the aerosol matrix 303 (or smoke-generating medium) refers to a mixture that can release aerosols (i.e. smoke), and its main components are nicotine substances, fogging agents and tobacco flavorings.

[0038] The concept of nicotine substances here is used in a broad sense, including free nicotine alkaloids, other nicotine compounds, and nicotine derivatives. The molecular formula of nicotine is C1. 10 H 14N2, its chemical structure comprises a pyridine ring and a pyrrolidine ring, which are connected by a covalent bond, and the pyrrolidine ring also has a methyl substituent. The active ingredient of nicotine can be in a free or bound state, and its existence can include: nicotine and nicotine salts naturally occurring in or extracted from tobacco plants, as well as synthetic nicotine and synthetic nicotine salts.

[0039] Tobacco plants typically contain nicotine bases and nicotine salts, such as nicotine citrate, nicotine malate, and nicotine tartrate; they also contain trace amounts of other nicotine compounds, such as nornicotine, anatabine, myosmine, and anabasine.

[0040] Synthetic nicotine is mainly produced through multi-step synthesis using nicotinic acid or 3-acetylpyridine as starting materials, or through asymmetric synthesis, biological or enzymatic synthesis methods to generate nicotine in its free base form. Synthetically produced nicotine salts mainly include: nicotine benzoate, nicotine salicylate, nicotine lactate, nicotine hydrochloride, nicotine citrate, nicotine tartrate, and nicotine malate, etc.

[0041] To form stable and dense smoke, in some applications, different polyols or mixtures thereof are added to the aerosol matrix 303 as fogging agents, such as propylene glycol, vegetable glycerin, and polyethylene glycol, and may also include esters of polyhydroxy alcohols or esters of hydroxy acids. These fogging agents have significantly different volatilization temperatures; for example, glycerol and 1,3-butanediol have boiling points of 290°C and 207.5°C, respectively, at 760 mmHg. However, this invention defines the boiling point temperature range as 180-350°C.

[0042] The function of tobacco flavorings and fragrances is to impart various flavors to aerosols. They contain natural flavorings such as vanillin, menthol, eugenol, citral, linalool, ethyl acetate, and other fruit and spice extracts; and synthetic flavorings such as acetylpyrazine, diacetyl, cyclic ketones, and various esters.

[0043] When inhaling the heated tobacco cartridge 10, nicotine is one of the key components ingested by the user. At the same time, abundant vapor production and diverse flavors are also important factors in enhancing the user experience. To this end, this design incorporates composite linear materials 302, which involves distributing the aerosol matrix 303 into a linear carrier substrate 302a, or preparing the carrier substrate 302a containing the aerosol matrix 303 into a linear shape. These composite linear materials 302 are coated with a linear heating element 302b to construct the basic unit of the smoke-generating body 3.

[0044] Typically, tobacco cartridges 10 can be classified according to the shape of their smoke-generating body 3 constituent units. Currently, the most common types include sheet-type tobacco cartridges 10 and granular tobacco cartridges 10.

[0045] In the thin-film type tobacco cartridge 10, the main component of the smoke-generating body 3 is a layered stack of tobacco sheets, which are arranged in an orderly manner.

[0046] Tobacco sheets are a type of reconstituted tobacco, made from tobacco as raw material with the addition of cellulose, flavorings, fogging agents, preservatives, and adhesives. The main production processes include rolling, papermaking, and slurry processing.

[0047] In the molding process of the thin-film tobacco cartridge 10, the tobacco sheet needs to be longitudinally cut and then rolled and bonded into a smoking rod. This process has high requirements for the dimensional accuracy, material uniformity, tensile strength and other material parameters of the tobacco sheet, otherwise it is easy to break.

[0048] Within the sub-category of thin-film tobacco cartridges 10, there is also an electromagnetically heated thin-film tobacco cartridge 10. In the high-speed mass production of this type of cartridge 10, tobacco sheets and metal strips need to be wound together. The metal strip is wound to the central area and then wrapped around the tobacco sheet to form a continuous three-bar smoke-generating body, which is then cut into individual segments. Because the metal strip is typically thick and wide (e.g., approximately 4mm wide and greater than 0.07mm thick), cutting often faces problems such as high resistance, rapid tool wear, and severe deformation of the metal strip. Furthermore, this structure places the metal strip at the center of the cartridge 10, which is a central heating method. Its disadvantages include overly concentrated heat, leading to uneven carbonization and significant fluctuations in aerosol release between different puff counts, affecting the consistency of the vaping experience.

[0049] In the thin-film type tobacco cartridge 10, the main component of the smoke-generating body 3 is a layered stack of tobacco sheets, which are arranged in an orderly manner.

[0050] In the granular tobacco cartridge 10, the main component of the smoke-generating body 3 is tobacco particles or herbal particles, and its structure is in a disordered filling state.

[0051] Within the sub-field of granular e-cigarette cartridges 10, there is also an electromagnetically heated granular e-cigarette cartridge 10. In the high-speed mass production of this type of cartridge 10, the heating element 302b (magnetic metal sheet) needs to be inserted into the cartridge 10 piece by piece. If the metal sheet is too thin, it is prone to deformation during insertion, making it impossible to guarantee the expected position and shape; if the metal sheet is too thick, there are problems with cutting difficulties and tool wear. Furthermore, this disordered particle arrangement structure makes the smoke-generating body 3 prone to defects such as unstable airflow and inconsistent carbonization areas during heating.

[0052] To address the aforementioned technical problems, this application designs a tobacco cartridge 10, one structural configuration of which is shown in Figure 1, including: a filter tip 1, a cooling component 2, a smoke-generating body 3, a smoke tube 4, and a plug 5. In this embodiment, the lengths of the filter tip 1, the cooling component 2, and the smoke-generating body 3 are 11mm, 18mm, and 16mm, respectively; these three components are enclosed by the smoke tube 4, forming a three-section tobacco cartridge 10. The outer diameter of the tobacco cartridge 10 can be 7.2mm, and the total length is 45mm. The outermost layer of the smoke-generating body 3 is a shaping layer 301, which can be composed of a thin aluminum foil composite paper with an average wall thickness of 0.3mm. The shaping layer 301 contains multiple linear elements, and an aerosol matrix 303 is diffusely distributed on its surface and inside. The linear elements are intertwined, forming wire gaps 304 between them.

[0053] The wire gap 304 is incorporated into the air passage. Furthermore, this wire gap 304 is controllable; its size is controlled by adjusting the outer diameter of adjacent slender wires (e.g., using composite wire 302, or wires composed solely of the carrier substrate 302a), thereby controlling the equivalent inner diameter of the air passage. If the air passage of the smoke generator 3 is divided radially, the size of the wire gap 304 can be controlled by adjusting the outer diameter of adjacent slender wires in different zones, thus controlling the equivalent inner diameter of the air passage in different zones. This satisfies the need for localized adjustments to suction resistance and air intake volume due to uneven heating and varying smoke output in the smoke generator 3.

[0054] For example, the shaping layer 301 can be made of aluminum foil 301a and pine paper 301b. The lengths of the filter tip 1, cooling component 2, smoke generator 3, and bottom plug 5 can be 11mm, 18mm, 12mm, and 4mm respectively. The four components are wrapped by the smoke tube 4 to form a four-section electromagnetic cartridge 10. The outer diameter of the cartridge 10 is 7.2mm and the total length is 45mm. The shaping layer 301 is a thin pine paper with a thickness of 0.025mm. The bottom plug 5 can be made of porous cellulose acetate, and its functions include preventing tobacco dust and tar leakage, slowing down aerosol condensation, and improving the aesthetics of the cartridge 10.

[0055] Referring to Figures 2 to 20, as an improvement of this application, in some embodiments of this application, the smoke-generating body 3 includes: a carrier substrate 302a and a heating element 302b.

[0056] For example, the carrier 302a is configured to support the aerosol matrix 303; the heating element 302b is configured to heat the aerosol matrix 303; wherein the carrier 302a covers at least a portion of the heating element 302b; the carrier 302a and the heating element 302b are constructed to form a composite linear 302.

[0057] It should be noted that the "coverage" referred to in this application does not only refer to complete adhesion. As shown in Figures 2 and 3, the substrate 302a being positioned around and in contact with the heating element 302b is also one type of "coverage" as referred to in this application. The "coverage" referred to in this application can be understood as satisfying the following two characteristics: being positioned outside the heating element 302b and in contact with the heating element 302b; however, the area and form of contact are not required. Common covering methods include: weaving, knitting, wrapping, layering, wrapping, and bundling.

[0058] It is understood that the composite linear object 302, the carrier linear object 3021, and the heating linear object 3022 in this application all belong to the linear objects defined in this application. The linear object defined in this application refers to an object that can be flexibly or plastically extended, and whose length dimension in the extension direction is much larger than the maximum cross-sectional dimension, and whose length-to-diameter ratio (the ratio of length to the maximum cross-sectional dimension) is greater than 5.

[0059] Linear materials include: metal wires, metal strips, metal rods, etc., made of metallic materials; and fiber filaments, fiber threads, fiber strips, fiber rods, fiber ropes, etc., made of organic and / or non-metallic inorganic materials. These linear materials can be mutually covered by methods such as weaving, weaving, winding, layering, wrapping, and bundling to form a composite linear material 302 structure. Therefore, the "covering" mentioned in this application refers to achieving mutual contact and coverage between linear materials through the above-mentioned methods.

[0060] Referring to Figures 3 to 7, the cross-section of the linear object in this application is equiaxed or approximately equiaxed, meaning that the difference between any two mutually perpendicular dimensions of the cross-section is small (the ratio of the difference to the larger dimension is less than 30%). As another embodiment, referring to Figure 14, the cross-section of the linear object in this application may also have a dimension in one direction that is significantly larger than the dimension in another direction (the ratio of the difference to the larger dimension is greater than 50%). In this case, the linear object in this application is more consistent with the common understanding of the shape of a "strip," therefore, the "line" in the name of the linear object in this application should not be considered a limitation on the cross-section. The linear object in this application simultaneously includes at least the two embodiments described above.

[0061] The composite linear material 302 in this application can be understood as an integral part consisting of a carrier substrate 302a and a heating element 302b. This integral part is constructed as a composite linear material 302 consisting of a carrier substrate 302a and a heating element 302b using the aforementioned covering method. Typical covering methods, such as twisted spinning, spiral winding, flat or oblique roll wrapping, and layered composite, all have good manufacturability.

[0062] Referring to Figure 4, in this scheme, the carrier 302a completely covers the heating element 302b (fully and tightly adheres to it), that is, the heating element 302b is completely enclosed inside the carrier 302a.

[0063] Referring to Figures 5 and 6, the substrate 302a is still tightly attached to the heating element 302b, but a portion of the heating element 302b is exposed in the external space.

[0064] Referring to Figure 8, the substrate 302a can simultaneously cover multiple heating elements 302b.

[0065] Referring to FIG9, in one embodiment, the carrier 302a may wrap around the heating element 302b in a winding manner.

[0066] Referring to Figure 7, the difference between this embodiment and the one shown in Figure 4 is that the outer substrate 302a (existing as an outer covering layer) has several local through-hole channels 308 penetrating the outer covering layer; these through-hole channels 308 connect the heating element 302b to the outside. This allows for the effective transfer of heat generated by the heating element 302b (including but not limited to contact conduction, convection, and radiation). It should be emphasized that this structural design can improve the heat transfer speed and heating uniformity on the one hand, and further refine and homogenize the airflow channels on the other.

[0067] In one embodiment, the internal and external positional relationship between the carrier substrate 302a and the heating element 302b can also be reversed, that is, the heating element 302b can cover the carrier substrate 302a, and the heating element 302b can form multiple through channels 308.

[0068] Additionally, it should be noted that the extension direction of the body-penetrating channel 308 can be perpendicular to the extension direction of the composite linear material 302, or it can intersect the extension direction of the composite linear material 302 at an angle.

[0069] Referring to Figure 9, when the carrier 302a winds the heating element 302b, the portion not covered by the carrier 302a can also be used as the through-body channel 308 of this application. Alternatively, the inner and outer relationships of the carrier 302a and the heating element 302b can be interchanged; that is, the carrier 302a is located inside, and the heating element 302b is spirally wound on the periphery, or the heating element 302b is located inside, and the carrier 302a is spirally wound on the periphery. In this case, the two partially cover each other, and the spiral winding gap on the periphery constitutes the through-body channel 308.

[0070] Based on the above description, it can be understood that in this application, at least a portion of at least one of the carrier substrate 302a and the heating element 302b covers at least a portion of the other; one of the carrier substrate 302a and the heating element 302b located on the periphery is provided with a through-body channel 308 so that the internal element communicates with the outside; the extending direction of the through-body channel 308 intersects with the extending direction of the whole.

[0071] Referring to FIG7, in one specific embodiment, different through-body channels 308 have different extending directions.

[0072] In one embodiment, in the extension direction of the composite linear 302 (i.e., the whole consisting of the heating element 302b and the carrier 302a), at least a portion of the heating element 302b covers at least a portion of the carrier 302a; in a first interval in the extension direction of the whole, at least a portion of the carrier 302a covers at least a portion of the heating element 302b; and in a second interval in the extension direction of the whole, at least a portion of the heating element 302b covers at least a portion of the carrier 302a.

[0073] That is, the carrier 302a and the heating element 302b can be alternately set as the outer part in different positions, thus forming an alternating winding or covering structure.

[0074] The presence of the through-body channel 308 enables heat transfer (including but not limited to contact conduction, convection or radiation) or aerosols to be effectively diffused or transferred through the through-body channel 308, thereby ensuring the efficiency of energy or material diffusion while achieving the synchronous extension of the substrate 302a and the heating element 302b.

[0075] Referring to Figures 14 and 15, it should be noted that the "coverage" referred to in this application does not mean that the substrate 302a and the heating element 302b need to be covered along their entire length, but only need to be covered in certain cross-sections.

[0076] In one specific embodiment, the substrate 302a can be various natural fibers (plant fibers and mineral fibers) or chemical fibers (man-made fibers, synthetic fibers, and inorganic fibers) that do not contain nicotine-containing substances. Suitable natural fibers include plant fibers and mineral fibers that can withstand high temperatures of 250°C.

[0077] Plant fibers include: seed fibers, bast fibers, leaf fibers, and fruit fibers. Seed fibers are single-celled fibers formed from the epidermal cells of some plant seeds, such as cotton and kapok. Bast fibers are single-celled or processed fibers obtained from the phloem of some plants, such as flax, ramie, jute, and bamboo fibers. Leaf fibers are processed fibers obtained from the leaves or leaf sheaths of some plants, such as sisal and abaca. Fruit fibers are fibers obtained from the fruits of some plants, such as coconut fiber.

[0078] Mineral fibers are fibers obtained from fibrous mineral rocks. Their main components are various oxides, such as silicon dioxide, aluminum oxide, and magnesium oxide. Their main source is various types of asbestos, such as chrysotile and crocidolite.

[0079] Suitable chemical fibers are fibers that have been chemically processed, including non-toxic and easily cut man-made fibers, synthetic fibers, and inorganic fibers.

[0080] Man-made fibers, also known as regenerated fibers, refer to textile fibers made from materials containing natural or protein fibers, such as wood, sugarcane, reeds, and soybean protein fibers, through chemical processing. These fibers are then modified to prepare fiber yarns suitable for this invention. The main suitable man-made fibers include viscose fiber, modal fiber, bamboo fiber, and acetate fiber.

[0081] Synthetic fibers are first synthesized from substances that do not inherently contain cellulose or protein, such as petroleum, coal, natural gas, limestone, or agricultural byproducts. These are then processed into fibers using chemical synthesis and mechanical processing. Finally, they are modified to be heat-resistant by adding flame-retardant substances or altering their composition. For example, polyester fibers, polyamide fibers, nylon fibers, aromatic polyamide fibers, polytetrafluoroethylene fibers, and polyimide fibers can be modified to withstand temperatures of 250°C or even 400°C, making them suitable for use as aerosol carriers in this invention. Simultaneously, at these high temperatures, they do not undergo significant chemical reactions, release harmful substances, produce unpleasant odors, or generate large amounts of dust.

[0082] Inorganic fibers are made from natural inorganic materials or carbon-containing polymer fibers through artificial spinning or direct carbonization, including glass fibers, metal fibers and carbon fibers.

[0083] For example, the 302a substrate needs to withstand temperatures of 300°C to 400°C. Suitable substrates include polytetrafluoroethylene (PTFE) fibers, certain aromatic polyamide fibers, and polyimide fibers, whose safe operating temperature is between 250-500°C. Graphite fibers can withstand temperatures of 1500-3000°C; glass fibers have excellent heat resistance, with a decomposition temperature exceeding 500°C; para-aramid (PPTA), such as DuPont's Kevlar or Teijin's TWARON, has a limiting oxygen index of around 30 and a decomposition temperature as high as 560°C; meta-aramid (MPIA), such as DuPont's Nomex, has a thermal decomposition temperature of 430°C; and some ceramic fibers, such as Nextel alumina ceramic fibers, can withstand temperatures up to 1200°C.

[0084] The heating element 302b can be made of any material that can generate heat under the action of a physical field (such as an electromagnetic field, electric field, or optical field). For example, magnetic materials, wave-absorbing materials, and light-absorbing materials.

[0085] The first type of material in the heating element 302b is a magnetically conductive material, exhibiting ferromagnetism or subferromagnetism, suitable for electromagnetic induction heating mode, which belongs to magnetic field heating. That is, the heating element 302b generates eddy current effect and hysteresis loss effect in a changing magnetic field, thereby achieving efficient, non-contact induction heating. Its basic composition is at least one of elemental metal, single alloy, and composite metal. Examples of single-element metal wires include iron (Fe) wire, nickel (Ni) wire, and cobalt (Co) wire; examples of single-alloy wires include alloy wires based on iron, nickel, and cobalt elemental materials that have been doped and modified to form wires; also including various magnetic stainless steel wires (such as ferritic stainless steel, martensitic stainless steel, and some cold-worked austenitic stainless steel), various soft magnetic alloys (such as permalloy, iron-based amorphous alloys, cobalt-based amorphous alloys, iron-based nanocrystalline alloys, iron-silicon-aluminum alloys, Invar alloys, and constant expansion alloys) wires, and Kovar alloy wires, as well as alloy wires based on these single-alloy wires that have been doped and modified to form wires; composite metal wires contain wires composed of two or more metal materials, including at least one magnetic material. Composite refers to the combination of two or more metal materials through rolling, electroplating, electroless plating, sputtering, welding, cladding, and coating (spinning, weaving, winding, layering, wrapping, and bundling).

[0086] The second type of material in the heating element 302b is an absorbing material, which can effectively absorb incident electromagnetic waves of a specific frequency band (radio frequency / microwave) and efficiently convert electromagnetic energy into heat energy through mechanisms such as dielectric loss and resistive loss. This type of material is suitable for radio frequency heating or microwave heating modes, belonging to electric field heating. Its heating originates from the direct action of the electromagnetic field on the polar molecules, ions, or free electrons within the material, enabling rapid and uniform volume heating or surface heating. Its basic composition consists of at least one of the following: elemental material, composite material, or modified functional material. Specific examples of microwave absorbing materials include: (1) carbon-based materials, such as carbon fiber filaments, graphene fibers, carbon nanotube yarns, and conductive carbon black composite filaments; (2) ceramic-based materials, such as silicon carbide fibers, silicon nitride composite fibers, and barium titanate-based ferroelectric ceramic filaments; (3) metal oxides and ferrites, such as zinc oxide whisker fibers, manganese zinc or nickel zinc ferrite composite filaments; (4) conductive polymers and composite materials, such as polyaniline, polypyrrole conductive fibers, or composite filaments made by doping metal particles (silver, copper, nickel) into matrix resins; (5) structural composite materials, such as functionalized fibers or filaments made by loading the above-mentioned microwave absorbing components with glass fiber or polymer fiber as the matrix through coating, impregnation or blending.

[0087] The third type of material in the heating element 302b is a light-absorbing material, a functional material with high absorption rate at specific wavelengths (such as infrared, near-infrared, or visible light bands) and the ability to efficiently convert light energy into heat energy. This type of material is suitable for photothermal modes (such as laser heating), belonging to optical field heating. Its heating originates from the energy of photons being absorbed by the material and converted into lattice vibration energy (heat energy) through non-radiative relaxation, enabling precise, localized, and rapid light-to-heat conversion. Its basic composition consists of at least one of the following: an element with high light absorption characteristics, a compound, a composite material, or a surface-treated functional material. Specific examples of light-absorbing materials include: (1) metals and alloys: such as nanoparticle-coated fibers or metal film-wrapped filaments of gold, silver, aluminum, and nickel, which enhance light absorption by utilizing their plasma resonance effect; (2) carbon-based materials, such as carbon black-coated fibers, graphene oxide fibers, and carbon nanotube yarns, which have near-perfect light absorption characteristics in a wide spectral range; (3) semiconductors and metal oxides, such as copper oxide, iron oxide, black silicon coatings, or composite filaments, which achieve efficient photothermal conversion through narrow band gaps or micro / nano structures; (4) ceramic materials, such as "MAX phase" ceramic filaments of titanium nitride and titanium carbide, or black alumina ceramic fibers, which have both high melting point and high light absorption rate; (5) organic polymers and dyes, such as polymer optical fibers or coated filaments doped with polydopamine coatings or near-infrared absorbing dyes (such as cyanines and phthalocyanines); (6) composite structural materials: such as functionalized wires made by modifying the surface of quartz or sapphire optical fibers with plasma nanoparticles or by preparing multilayer light-absorbing films using physical vapor deposition.

[0088] Referring to FIG2, in some embodiments of this application, the smoke-generating body 3 is constructed as being woven from composite thread 302.

[0089] Referring to Figures 6, 14 and 15, in some embodiments of this application, the angle at which the substrate 302a covers the heating element 302b in a cross-section perpendicular to the extension direction of the composite linear material 302 is defined as the substrate coverage angle A1, and the value of the substrate coverage angle A1 ranges from 10 degrees to 360 degrees.

[0090] In some embodiments of this application, the angle at which the heating element 302b is exposed outside the substrate 302a in a cross-section perpendicular to the extension direction of the composite linear 302 is defined as the heating exposure angle A2, which ranges from 10 degrees to 180 degrees.

[0091] In this application, the substrate coverage angle A1 and the heat exposure angle A2 are both connected to the tangent of the cross-sectional shape of the substrate 302a with the center of the composite linear material 302 as the endpoint (the full coverage connection line coincides), thus forming opposite angles.

[0092] Generally speaking, the sum of the substrate coverage angle A1 and the heat exposure angle A2 should satisfy 360 degrees.

[0093] Referring to Figures 3, 5, and 6, in some embodiments of this application, in a cross-section perpendicular to the extension direction of the composite linear 302, at least a portion of the heating element 302b is exposed outside the substrate 302a.

[0094] Referring to Figures 9 to 13, in the extension direction of the composite linear material 302, the heating element 302b may also be at least partially exposed outside the substrate 302a.

[0095] In some embodiments of this application, at least a portion of the heating element 302b is configured as a heating wire 3022. Referring to FIG2, the heating wire 3022 and the composite wire 302 have the same extending direction.

[0096] In some embodiments of this application, at least a portion of the substrate 302a is configured as a linear support 3021. Referring to FIG2 and FIGS8 to 12, the extension direction of the linear support 3021 intersects obliquely with the extension direction of the composite linear support 302.

[0097] In some embodiments of this application, at least a portion of the heating element 302b is configured as a heating wire 3022; as shown in FIG2, the carrier substrate 302a is at least configured as a carrier wire 3021; ​​the carrier wire 3021 spirally surrounds the heating wire 3022.

[0098] Referring to Figure 10, as an extension, other heating wires 3022 can still be wound around the periphery of the heating wire 3022. Of course, non-heating metal wires can also be used for winding, which makes it easier to maintain the shape of the composite wire 302.

[0099] Referring to FIG11, in a specific embodiment, a base line 3021 and / or a heating line 3022 may be used to wrap around another base line 3021. When the wrapped base line 3021 partially covers the outside of the heating line 3022 (it is not covered in FIG10), it can be considered that the wrapped base line 3021 partially covers the heating line 3022, that is, the base 302a partially covers the heating element 302b.

[0100] In one embodiment, the wound heating wire 3022 in Figure 12 can be replaced by a pure reinforcing core 305. This reinforcing core 305 does not have a heating function and only serves as a support structure for the winding of the base wire 3021. Therefore, a wider range of materials can be selected, provided that it meets the following conditions: it has sufficient strength and does not release harmful substances or produce odors at the characteristic temperature of the smoking process (e.g., 250-350°C). Alternatively, the winding of the heating wire 3022 around the reinforcing core 305 can be omitted. In this configuration, the scheme shown in Figure 11 can be considered another implementation of the base wire 3021.

[0101] Referring to Figure 12, the wound structure can be a linear composite structure of the load line 3021 and the heating line 3022, such as the forms in Figures 5 and 6. They can have a common extension direction, but they form an enclosing relationship in the cross-section.

[0102] Referring to Figure 13, the wound structure can be a conjugate composite junction of the load line 3021 and the heating line 3022. That is, the load line 3021 and the heating line 3022 first cover each other, and then form a composite wire bundle on the outer surface by winding.

[0103] Referring to Figures 14 and 15, the wrapped structure can be either circular or waist-shaped, or other shapes can be selected according to specific needs.

[0104] Referring to FIG16, in one embodiment, in order to adjust the amount of aerosol volatilization or odor, the composite linear material 302 can be used as the core material 31, and a carrier substrate 302a can be attached to its outside as the covering material 32. The carrier substrate 302a can be a paste coated on the outside of the composite linear material 302, or it can be made into a sheet and attached to the outside of the composite linear material 302.

[0105] The composite linear material 302 serving as the core material 31 can be the scheme described in this application or a separate carrier substrate 302a.

[0106] In one embodiment, the core material 31 in the structure shown in FIG. 16 may also be composed solely of a carrier substrate 302a. Additionally, the covering material 32 may cover the entire structure composed of multiple core materials 31 as shown in FIG. 16, or it may cover individual core materials 31.

[0107] Referring to FIG16, in a specific embodiment, the covering material 32 may be disposed between the core material 31 and the shaping layer 301.

[0108] Referring to FIG17, in a specific embodiment, the covering material 32 can adopt a multi-layer structure. Each layer of the multi-layer structure can be composed of a carrier substrate 302a and a heating element 302b. The carrier substrate 302a can be disposed either inside or on the periphery of the heating element 302b. These configurations enable relatively uniform heating of the covering material 32.

[0109] Referring to Figures 18 to 20, as an embodiment of the smoke-generating body 3, a base region Z can be provided, mainly filled with the base material 302a. Within this base region Z, only the base material 302a can be filled, or a large amount of the base material 302a and a small amount of the heating element 302b can be filled. In this case, the base material 302a and the heating element 302b do not constitute a composite linear structure 302. The base material 302a can be constructed as a linear structure, or as a multi-layered sheet, or other forms. In one embodiment, within the cross-section of the smoke-generating body 3, the base region Z can be constructed as an annular region.

[0110] Referring to Figures 18 to 20, as an embodiment of the smoke generator 3, a clustering region SJ can be provided, into which a cluster (including multiple clusters) of the composite linear materials 302 provided in the above embodiment can be filled. The substrate region Z can partially or completely surround the clustering region SJ.

[0111] Referring to FIG18, in one embodiment, in order to heat the substrate region Z, a heating film 307 can be provided between the cigarette paper 306 (the outermost shaping part of the smoke-generating body 3) and the bundled region SJ. The heating film 307 can be understood as another form of heating element 302b, which constitutes an overall coverage of the substrate 302a.

[0112] Referring to FIG19, in one embodiment, the heating film 307 can be disposed between the cluster region SJ and the substrate region Z, that is, the substrate region Z is heated from the inside of the substrate region Z.

[0113] Referring to FIG20, in one embodiment, the heating film 307 in FIG19 can be replaced by a heating element 302b wound (e.g., spirally wound) around the periphery of the cluster region SJ, which is constructed as a heating wire 3022. The structural feature of this configuration is that the composite wire 302 within the cluster region SJ is "bundled" by the heating wire 3022.

[0114] This application adopts a combined structure of substrate region Z and cluster region SJ, which can reduce the manufacturing complexity of smoke generator 3, while achieving uniform heating through cluster region SJ, thereby fully volatilizing aerosols.

[0115] In summary, this application effectively solves the problem of uneven carbonization caused by the overly concentrated configuration of the heating element 302b in the traditional smoke-generating body 3 configuration, including phenomena such as local over-carbonization or under-carbonization, by using the covering structure between the substrate 302a and the heating element 302b, and the synergistic extension of the two in three-dimensional space.

[0116] Based on the above embodiments, it can be seen that the extension direction of the substrate 302a interferes with the extension direction of the heating element 302b, so that the substrate 302a and the heating element 302b are constructed as a whole that can extend synchronously.

[0117] The “interference in the extension direction” referred to here can be understood as including the coupling relationship between the substrate 302a and the heating element 302b in the extension direction, as well as the relative positional relationship formed by the mutual coverage of the substrate 302a and the heating element 302b.

[0118] Referring to Figures 21 to 23, based on the above embodiments, the heating element 302b is discretely distributed at least in the first direction and the second direction, and the carrier 302a is correspondingly distributed with the carrier 302a at least in the first direction and / or the second direction.

[0119] The phrase "discrete distribution in the first and second directions" as used here means that in a cross section parallel to the first and second directions (the plane of the paper shown in Figure 21), the cross-sectional profile of the heating element 302b (or the carrier 302a) is discretely distributed in both the first direction (at different positions in the first direction) and the second direction (at different positions in the second direction).

[0120] The phrase "the heating element 302b is distributed correspondingly with the carrier 302a at least in the first direction and / or the second direction" means that the heating element 302b and the carrier 302a are correspondingly related and arranged close to each other in the first direction or the second direction.

[0121] In one specific embodiment, the carrier 302a is discretely distributed at least in the first and second directions. Referring to FIG22, the heating element 302b can also be discretely distributed at least in the third direction D3; the first and second directions are perpendicular to each other; the third direction D3 is perpendicular to the first and second directions respectively, that is, a rectangular coordinate system can be established by the first direction (X-axis direction), the second direction (Y-axis direction), and the third direction D3 (Z-axis direction) to determine different cross sections. Of course, a polar coordinate system can also be established to determine different cross sections. The difference in coordinate system will not change the relative positional relationship between the carrier 302a and the heating element 302b. That is, in this application, the first direction, the second direction, and the third direction D3 are only for establishing a relative positional relationship, not for establishing an absolute positional relationship.

[0122] Referring to Figure 23, in order to characterize the dispersion of linear distribution in the smoke-generating body 3 structure, this application defines two key parameters. First, this application defines the "layout interval length," which is the maximum distance of the heating element 302b or the carrier 302a within the cross-section. Among them, the one parallel to the first direction is called the first type of layout interval length L1; the one parallel to the second direction is called the second type of layout interval length L2; and the one parallel to the third direction D3 is called the third type of layout interval length L3 (not shown in Figure 23).

[0123] Referring to Figure 23, after projecting the cross-sectional profile formed by a certain type of object (such as the heating element 302b or the carrier 302a) in a certain cross-section into a certain direction, the distance between the two farthest profile points is defined as the length of the layout interval in that direction.

[0124] For example, the length of the layout interval in the first direction D1 is defined as the first type of layout interval length L1 (at this time, the cross section is parallel to the first direction D1 and the second direction D2, or the cross section can also be parallel to the first direction D1 and the third direction D3, the same below); the length of the layout interval in the second direction D2 is defined as the second type of layout interval length L2 (at this time, the cross section is parallel to the first direction D1 and the second direction D2, or the cross section can also be parallel to the second direction D2 and the third direction D3, the same below); the length of the layout interval in the third direction D3 is defined as the third type of layout interval length L3 (at this time, the cross section is parallel to the first direction D1 and the third direction D3, or the cross section can also be parallel to the second direction D2 and the third direction D3, the same below).

[0125] To measure the dispersion of the capabilities provided by a physical entity (such as heating capacity or the ability to support the aerosol matrix 303), this application defines the ratio of the total mass M of a certain type of object (such as heating element 302b or carrier 302a) in the smoke-generating body 3 to the length L1 of the first type of arrangement interval as the "probable dispersion in the first direction D1", with units of mg / mm. If the "probable dispersion in the first direction D1" is expressed as d1, then d1 = M / L1.

[0126] The ratio of the mass of the heating element 302b or the carrier 302a to the length L2 of the second type of layout interval is defined as the "probability of dispersion in the second direction D2"; wherein, if the "probability of dispersion in the first direction D1" is expressed as d2, then d2 = M / L2.

[0127] The ratio of the mass of the heating element 302b or the carrier 302a to the length L3 of the third type of layout interval is defined as the "probability of dispersion in the third direction D3"; where, if the "probability of dispersion in the first direction D1" is expressed as d3, then d3 = M / L3.

[0128] For the first type of deployment interval length L1, there are actually two corresponding cross sections, namely the plane parallel to the first direction D1 and the second direction D2, and the plane parallel to the first direction D1 and the third direction D3. Therefore, the probability dispersion of the first direction D1 can actually measure the degree of dispersion of the capabilities provided by the entity in two dimensions; the probability dispersion of the second direction D2 and the probability dispersion of the third direction D3 are the same.

[0129] Because the cross-sections are different, the length of the layout interval will vary (this is true for all three dimensions). The largest of the probabilistic dispersions obtained from all cross-sections is defined as the most probabilistic dispersion.

[0130] In one specific embodiment, the probabilistic dispersion of the heating element 302b ranges from 0.02 to 40 mg / mm, and the most probabilistic dispersion of the heating element 302b ranges from 10 to 40 mg / mm.

[0149] In other embodiments, the most probable dispersion of the third-direction D3 of the heating element 302b can be in the range of 16-24 mg / mm.

[0150] In a specific embodiment, the probable dispersity of the substrate 302a obtained from all cross sections ranges from 4 to 2500 mg / mm; the most probable dispersity of the substrate 302a ranges from 1000 to 2500 mg / mm.

[0154] In other embodiments, the most probable dispersity of the substrate 302a is in the range of 1000-2000 mg / mm.

[0155] In a specific embodiment, since the three-dimensional structure of the smoke-generating body 3 has an orientational design, such as being configured as a cylinder or other three-dimensional shape with obvious length orientation, the probability dispersion of the first direction D1, the second direction D2, and the third direction D3 is also different.

[0163] In other embodiments, the probabilistic dispersion of the second direction D2 of the substrate 302a ranges from 50 to 500 mg / mm.

[0164] In some embodiments, the most probable dispersion value of the second direction D2 of the substrate 302a is within the range of any two of 1000 mg / mm, 1100 mg / mm, 1850 mg / mm, 2035 mg / mm, and 2500 mg / mm.

[0167] In some embodiments of this application, the probable dispersibility of the third-direction D3 of the substrate 302a ranges from 4 to 2500 mg / mm; the maximum probable dispersibility of the third-direction D3 of the substrate 302a ranges from 1000 to 2500 mg / mm.

[0168] In some embodiments, the probabilistic dispersion of the third-direction D3 of the substrate 302a is within the range of any two of the following: 4 mg / mm, 10 mg / mm, 37 mg / mm, 58 mg / mm, 75 mg / mm, 100 mg / mm, 180 mg / mm, 255 mg / mm, 370 mg / mm, 420 mg / mm, 600 mg / mm, 790 mg / mm, 1100 mg / mm, 1850 mg / mm, 2035 mg / mm, and 2500 mg / mm.

[0169] In other embodiments, the probabilistic dispersion of the third-direction D3 of the substrate 302a ranges from 50 to 500 mg / mm.

[0170] In some embodiments, the most probable dispersion value of the third-direction D3 of the substrate 302a is within the range of any two of 1000 mg / mm, 1100 mg / mm, 1850 mg / mm, 2035 mg / mm, and 2500 mg / mm.

[0171] In other embodiments, the most probable dispersion of the third-direction D3 of the substrate 302a is in the range of 1200-2000 mg / mm.

[0172] Referring again to Figure 23, the ratio of the sum of the cross-sectional areas S of a certain type of object (such as the heating element 302b or the carrier 302a) in the smoke-generating body 3 to the corresponding layout interval length (such as the first type of layout interval length L1, the second type of layout interval length L2 or the third type of layout interval length L3) is defined as the area dispersion s, and its unit is mm.

[0173] The ratio of the sum of the cross-sectional areas S of a certain type of object (such as the heating element 302b or the carrier 302a) in the cross section to the length L1 of the first type of layout interval is defined as the area dispersion s1 of the first direction D1.

[0174] For example, if the sum of the cross-sectional areas of the first type of layout interval length L1 in the two corresponding sections is represented as S12 and S13 respectively, then s1 = S12 / L1 or s1 = S13 / L1.

[0175] The ratio of the sum of the cross-sectional areas S of a certain type of object (such as the heating element 302b or the carrier 302a) in the cross section to the length L2 of the second type of layout interval is defined as the area dispersion s2 of the second direction D2.

[0176] For example, if the sum of the cross-sectional areas of the second type of layout interval length L2 in the two corresponding sections is represented as S21 and S23 respectively, then s2 = S21 / L1 or s2 = S23 / L1.

[0177] The ratio of the sum of the cross-sectional areas S of a certain type of object (such as the heating element 302b or the carrier 302a) in the section to the length L3 of the third type of layout interval is defined as the area dispersion s3 of the third direction D3.

[0178] For example, if the sum of the cross-sectional areas of the third type of layout interval length L3 in the two corresponding sections is expressed as S31 and S32 respectively, then s3 = S31 / L3 or s3 = S32 / L3.

[0179] Understandably, area dispersion measures the dispersion of the area occupied by an object in a cross section and in the corresponding direction. It measures the dispersion of the volume (decomposed into area) of the corresponding object (such as the heating element 302b or the carrier 302a). A more appropriate dispersion can improve the corresponding heating or atomization effect (aerosol volatilization) while ensuring volume reduction.

[0217] In other embodiments, the maximum area dispersion of the third-direction D3 of the substrate 302a ranges from 10 to 14 mm.

[0218] Referring to Figure 25, in this application, a hexahedral solid space is constructed with the cross-section of the smoke-generating body 3 (excluding the cross-section tangent to the edge of the smoke-generating body 3) as the boundary, which is defined as the unit layout space SP. The specific construction method of the unit layout space SP is as follows:

[0219] Two parallel cross sections spaced 1 mm apart form two opposite faces of a hexahedron; another set of two parallel cross sections spaced 1 mm apart (perpendicular to the previous set of cross sections) forms another two opposite faces of the hexahedron; then a third set of two parallel cross sections spaced 1 mm apart (perpendicular to the previous two sets) forms another two opposite faces of the hexahedron. This constitutes the six boundaries of the unit layout space SP of this application.

[0220] Taking Figure 25 as an example, two cross sections perpendicular to the second direction D2, which are 1 mm apart, are used as the first set of relative boundaries of the unit layout space SP; two cross sections perpendicular to the third direction D3, which are 1 mm apart, are used as the second set of relative boundaries of the unit layout space SP; and two cross sections perpendicular to the first direction D1, which are 1 mm apart, are used as the third set of relative boundaries. In this way, a unit layout space SP with a volume related to the length L1 of the first type of layout interval is formed, which is defined as the first type of unit layout space SP.

[0221] It is understandable that, in a similar manner, unit deployment spaces SP related to the second type deployment interval length L2 and the third type deployment interval length L3 can be constructed respectively, and they can be defined as the second type unit deployment space SP and the third type unit deployment space SP.

[0222] The spatial dispersion is defined as the ratio of the mass of a certain type of object (such as the heating element 302b or the carrier 302a) in the smoke-generating body 3 within a unit layout space SP to the volume of the unit layout space SP.

[0223] For example, spatial dispersion can be divided into three categories based on the orientation of the length direction: first type spatial dispersion, second type spatial dispersion, and third type spatial dispersion.

[0224] That is, the ratio of the mass of a certain type of object (such as the heating element 302b or the carrier 302a) in the smoke-generating body 3 to the volume of the first type of unit layout space SP is defined as the first type of spatial dispersion; the ratio of the mass of a certain type of object (such as the heating element 302b or the carrier 302a) in the smoke-generating body 3 to the volume of the second type of unit layout space SP is defined as the second type of spatial dispersion; and the ratio of the mass of a certain type of object (such as the heating element 302b or the carrier 302a) in the smoke-generating body 3 to the volume of the third type of unit layout space SP is defined as the third type of spatial dispersion.

[0225] Specifically, if the first type of spatial dispersion is represented as m1, the mass of a certain type of object in the smoke-generating body 3 (such as the heating element 302b or the carrier 302a) within the first type of unit layout space SP is represented as M1, and the volume of the first type of unit layout space SP is represented as V1, then m1 = M1 / V1, with units of mg / mm3; if the second type of spatial dispersion is represented as m2, the mass of a certain type of object in the smoke-generating body 3 (such as the heating element 302b or the carrier 302a) within the second type of unit layout space SP is represented as M2, and the volume of the second type of unit layout space SP is represented as V2, then m2 = M2 / V2; if the third type of spatial dispersion is represented as m3, the mass of a certain type of object in the smoke-generating body 3 (such as the heating element 302b or the carrier 302a) within the third type of unit layout space SP is represented as M3, and the volume of the third type of unit layout space SP is represented as V3, then m3 = M3 / V3.

[0226] It is understandable that spatial dispersion can measure the dispersion of an object in a unit deployment space SP and the corresponding direction. It can measure the dispersion of the mass of the corresponding object (such as the heating element 302b or the carrier 302a). A more suitable dispersion can ensure uniform mass distribution and thus improve the corresponding heating or atomization effect (aerosol volatilization).

[0227] Similarly, due to different cross sections, the length of the layout interval will change (this is true for all three dimensions), and the maximum spatial dispersion obtained from all cross sections is defined as the maximum spatial dispersion.

[0228] In one specific embodiment, the spatial dispersion of the heating element 302b ranges from 0.1 to 24 mg / mm3; the maximum spatial dispersion of the heating element 302b ranges from 16 to 24 mg / mm3.

[0269] In other embodiments, the third maximum spatial dispersion of the substrate 302a ranges from 0.7 to 0.9 mg / mm3.

[0270] To describe the matching state between the linear elements in the smoke-generating body 3, this application also proposes and defines the concept of "accompaniment degree". Accompaniment degree is a dimensionless parameter, specifically referring to the ratio of the dispersion of the heating element 302b to the dispersion of the carrier 302a. Since the dispersion provided by the technical solution of this application includes probabilistic dispersion, area dispersion, and spatial dispersion, the accompaniment degree of this application also includes probabilistic accompaniment degree, area accompaniment degree, and spatial dispersion degree.

[0271] The probabilistic degree of this application ranges from 0.000008 to 10; the area degree of this application ranges from 0.0015 to 0.5; and the spatial degree of this application ranges from 0.0625 to 240.

[0272] In some embodiments, the probability of association of this application ranges from 0.005 to 0.016; the area association of this application ranges from 0.01 to 0.075; and the spatial association of this application ranges from 1 to 15.

[0273] In one specific embodiment, the maximum range of the degree of association (including all degrees of association) of this application is from 0.000008 to 1000.

[0274] In other embodiments, the degree of association (including all degrees of association) of this application ranges from 10 to 1000; the maximum degree of association (based on the maximum dispersion, including all degrees of association) of this application ranges from 10 to 1000.

[0275] The probabilistic, area, and spatial adjoint degrees of this application may further include the following adjoint degrees for each direction:

[0276] The ratio of the probable dispersion of the heating element 302b to that of the substrate 302a in the first direction D1 can be defined as the probable adjointness of the first direction D1. Similarly, the ratio of the probable dispersion of the heating element 302b to that of the substrate 302a in the second direction D2 can be defined as the probable adjointness of the second direction D2. The ratio of the probable dispersion of the heating element 302b to that of the substrate 302a in the third direction D3 can be defined as the probable adjointness of the third direction D3.

[0277] The ratio of the area dispersion of the heating element 302b to that of the substrate 302a in the first direction D1 can be defined as the area dispersion of the first direction D1. Similarly, the ratio of the area dispersion of the substrate 302a to that of the heating element 302b in the second direction D2 can be defined as the area dispersion of the second direction D2. The ratio of the area dispersion of the substrate 302a to that of the heating element 302b in the third direction D3 can be defined as the area dispersion of the third direction D3.

[0278] The ratio of the first type of spatial dispersion of the heating element 302b to that of the carrier 302a can be defined as the first type of spatial accompaniment; similarly, the ratio of the second type of spatial dispersion of the carrier 302a to that of the heating element 302b can be defined as the second type of spatial accompaniment; and the ratio of the third type of spatial dispersion of the carrier 302a to that of the heating element 302b can be defined as the third type of spatial accompaniment.

[0279] It is understandable that the various associated degrees mentioned above (probability associated degree, area associated degree, and spatial associated degree, as well as their individual associated degrees in each direction) can all be calculated from the various dispersion degrees mentioned above, and the specific range of values ​​will not be elaborated here.

[0280] The degree of association essentially measures the degree of matching and following between the heating element 302b and the carrier 302a in spatial distribution. Generally, a larger degree of association indicates a higher degree of synchronization between the distribution dispersion characteristics of the heating element 302b and the carrier 302a in that direction; a smaller degree of association indicates a lower degree of synchronization between the distribution dispersion characteristics of the heating element 302b and the carrier 302a in that direction.

[0281] By controlling the degree of accompaniment, it can be ensured that the heat generated by the heating element 302b can be uniformly absorbed and transferred by the substrate 302a, thereby achieving a consistent carbonization effect in three-dimensional space. This is also one of the key mechanisms for solving the problem of uneven carbonization in this application.

[0282] By using the correspondence under discrete distribution and the corresponding parameter settings, the heating element 302b of this application can be effectively distributed in space and can also be effectively heated by following the arrangement of the carrier substrate 302a.

[0283] Referring to FIG24, as another implementation of this application, the carrier 302a and / or heating element 302b are discretely distributed within the space defined by the smoke-generating body 3.

[0284] In the smoke-generating body 3, linear materials (which can be heating linear materials 3022, carrier linear materials 3021, or composite linear materials 302) are diffusely filled into the smoke-generating body 3; this can achieve a more uniform heating and smoke generation effect.

[0285] In the example, the carrier 302a and the heating element 302b overlap in a mixed manner within the space defined by the smoke-generating body 3.

[0286] In one specific embodiment, the carrier 302a and the heating element 302b constitute a three-dimensional nonwoven fabric, which can be formed by stacking nonwoven fabrics or by directly filling linear objects in three-dimensional space.

[0287] It is understood that the nonwoven fabric itself can be constructed as the linear material in this application (specifically, it can be the composite linear material 302), that is, it has the properties of the linear material in this application.

[0288] In one specific embodiment, in order to obtain a suitable mixing effect, the mass ratio of the heating element 302b to the carrier 302a ranges from 0.005 to 10.

[0289] In one specific embodiment, in order to ensure the effect of spatial dispersion, the curvature of the substrate 302a and / or the heating element 302b is set to a range of 0.02-2mm-1.

[0290] In some embodiments, the curvature of the substrate 302a and / or the heating element 302b is defined as a range consisting of any two values ​​from 0.02mm-1, 0.03mm-1, 0.04mm-1, 0.05mm-1, 0.06mm-1, 0.07mm-1, 0.08mm-1, 0.09mm-1, 0.1mm-1, 0.2mm-1, 0.3mm-1, 0.4mm-1, 0.5mm-1, 0.6mm-1, 0.7mm-1, 0.8mm-1, 0.9mm-1, 1mm-1, 1.1mm-1, 1.2mm-1, 1.3mm-1, 1.4mm-1, 1.5mm-1, 1.6mm-1, 1.7mm-1, 1.8mm-1, 1.9mm-1, and 2mm-1.

[0291] The curvature refers to spatial curvature, such as the degree of bending in the extension direction of a linear body. It geometrically describes the bending characteristics of the extension path of the linear body itself, affecting the uniformity of heat transfer along the path and the spatial coverage.

[0292] In one specific embodiment, the orientation distribution function of the substrate 302a and / or the heating element 302b has a preset orientation related to the length of the smoke-generating body 3. That is, the orientation trend of the substrate 302a and the heating element 302b can be set according to the length direction of the smoke-generating body 3, which makes it easier to control heating and smoke generation.

[0293] In one specific embodiment, a filler (not shown in Figure 24) may also be provided in this scheme. The filler is configured to fill at least between the carrier 302a and the heating element 302b. The filler can play a role such as bonding the smoke-generating body 3 into a whole and enhancing thermal conductivity.

[0294] This approach allows for a uniform spatial distribution of the substrate 302a or heating element 302b at the microscopic level, while the use of nonwoven technology can improve production efficiency.
