Description

[0001] This application claims priority to Chinese Patent Application No. 2025101071002, filed on January 22, 2025, entitled "Smoke Generating Device, Smoke Cartridge, Smoke Generating Body and Preparation Method", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electronic atomization technology, and in particular to a smoke generator, an aerosol generating product, and a heated non-combustible system. Background Technology

[0003] In the field of generating inhalable aerosols through low-temperature heating, the core functional components typically include a matrix for releasing volatile components upon heating and an integrated heating element. In recent years, an advanced design concept aimed at optimizing heat transfer efficiency and uniformity has garnered significant attention. This involves using precision textile or composite material processes to physically weave and composite metal heating wires (such as resistance wires) with matrix fibers made from specific plant materials at the microscopic or macroscopic scale, forming a unified, directly electrically heated functional fabric or entity. This integrated structural design aims to achieve uniform heat generation and transfer from multiple internal points, thereby improving the stability and consistency of the release of effective components.

[0004] However, existing technologies face a significant technological challenge in the manufacturing process of achieving the aforementioned integrated textile structure. Currently, to adapt to textile processing procedures, chopped fibers processed from plant materials are typically chosen as the functional matrix material. In subsequent processing steps such as carding, spinning, weaving, or lamination, these chopped fibers, due to their insufficient mechanical strength, limited length, and high brittleness, are prone to breakage, fuzzing, and the formation of process dust. This not only leads to raw material waste but, more importantly, severely disrupts the continuity and mechanical integrity of the constructed textile structure, directly resulting in a decrease in the functionality, durability, and production yield of the final product, thus hindering the large-scale production and commercial application of this high-performance design. Summary of the Invention

Detailed Implementation

[0022] 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.

[0023] This application provides a smoke-generating body; please refer to [link / reference]. Figure 4-6 The smoke-generating body 100 comprises multiple monomers 110. For example... Figure 3 At least one monomer 110 includes a core 111 and a winding element 112. The winding element 112 includes an aerosol generating matrix. The winding element 112 is spirally wound around the periphery of the core 111 along the axial direction of the core 111. Multiple monomers 110 are bundled or woven to form a smoke generator 100. The smoke generator 100 can generate aerosols when heated.

[0024] The smoke generator 100 is composed of several monomers 110, at least one of which includes a core 111 and a winding 112 surrounding the core 111. The winding 112 incorporates an aerosol-generating matrix, which, unlike traditional short fibers, possesses certain tensile and bending mechanical strength. In this structural design, the core 111 provides support, while the aerosol-generating matrix, with its enhanced mechanical properties, maintains continuity and prevents breakage during the further bundling or weaving of the monomers 110 into the complete smoke generator 100. This design helps improve the structural durability of the final product and increases production yield during manufacturing.

[0025] It should be noted that for a single unit 110 of a specific length, the length of the winding member 112 after unfolding along the axial direction of the core is greater than the axial length of the core 111, in order to meet the winding and covering requirements of the winding member 112 on the core 111. This covering requirement is based on the preset specifications of the smoke-generating body 100, such as the weight and outer diameter of the smoke-generating body 100. A higher degree of coverage per unit length of the axial direction of the single unit 110 indicates that the unfolded length of the winding member 112 is larger, and therefore the weight of the winding member 112 is larger, and the corresponding weight of the single unit 110 is larger. When the number of single units 110 in the smoke-generating body 100 is the preset amount, the weight of the smoke-generating body 100 is larger. Therefore, the unfolded length of the winding member 112 and the number of single units 110 can be precisely adjusted according to the specification requirements of the smoke-generating body 100, which is easier to achieve continuous production and precise control of production compared to traditional tobacco sheet products. The aforementioned degree of coverage can be calculated by the ratio of the coverage area of ​​the winding member 112 on the core 111 to the circumferential surface area of ​​the core 111, or by the ratio of the axial distance of the winding member 112 on the core 111 to the axial length of the core 111. A higher ratio indicates a higher degree of coverage. In addition, the winding member 112 is spirally wound on the core 111 with a preset helix angle (or winding angle). For the winding member 112 of the preset unfolded length, the aforementioned coverage can be adjusted by adjusting the helix angle. The helix angle is the ratio of the pitch to the outer diameter. The pitch is the distance the winding member travels axially for each rotation. The outer diameter is the circumference of the winding member 112 after winding. When the helix angle is smaller, the coverage is smaller, the winding member on the core 111 per unit length is shorter, and the load corresponding to the winding member 112 is smaller, and the weight of the unit length is smaller. Conversely, the larger the helix angle, the greater the coverage. However, in order to ensure the spiral winding structure, the helix angle must be greater than 0° and less than 90°, or between 10° and 80°, or between 30° and 50°.

[0026] In some embodiments, such as Figure 6 The radial cross section of the core 111 is one of a circle, an ellipse, a rounded rectangle, and a rectangle, or an equivalent shape to the aforementioned shapes. For example, the core 111 can be a sheet-like shape within a rectangle.

[0027] Bundling refers to the process of combining multiple monomers 110 into a strand through twisting, plying, or bonding. Textile fabrication refers to using multiple monomers 110 as warp or weft yarns, forming a two-dimensional or three-dimensional mesh or tubular structure through weaving, knitting, or nonwoven processes. For example, the smoke generator 100 can be a hollow tubular smoke generator 100 formed through weaving, a smoke generator 100 with an elastic mesh structure formed through knitting, or a nonwoven integrated smoke generator 100 formed through nonwoven processes.

[0028] In some embodiments of this application, the winding member 112 is a tobacco strip with a preset length.

[0029] This design allows the tobacco strips to be continuously and stably wound around the core 111, forming a uniformly structured winding layer. Compared to traditional short fibers or fragmented matrices, the winding morphology—the monomer—formed by the tobacco strips on the core 111 has higher tensile strength than the tobacco strips themselves. Therefore, it provides better physical integrity and is less prone to breakage or detachment during subsequent bundling and weaving processes. This ensures that the aerosol-generating matrix maintains its predetermined distribution and continuity throughout the entire smoke-generating body 100. This not only enhances the structural stability and durability of the smoke-generating body 100 but also improves operational stability and product consistency during production, ultimately contributing to higher overall product yield and a better user experience.

[0030] It should be added that the winding element 112 can be in the form of strips, ropes, tubes, and mesh strips, among other things. When the winding element 112 is rope-like, its material can be cotton thread, hemp thread, or synthetic fiber rope impregnated with a matrix. When the winding element 112 is tubular, it can specifically be a hollow tubular structure, which can be a thin-walled, compressible "micro-tube" filled or encapsulated with an aerosol generating matrix. The aerosol generating matrix can be encapsulated in the hollow tubular structure in the form of powder, granules, or gel. When the winding element 112 is a mesh strip, the aerosol generating matrix is ​​loaded onto the surface and mesh of the mesh strip in the form of a coating layer or impregnation layer.

[0031] As one of the specific forms of the winding component 112, the tobacco strip can be designed in a variety of ways according to the product function and process requirements. It includes at least one of the following: homogeneous thin strip, composite laminated strip, porous structure strip, surface textured strip, gradient density strip, and aroma-carrying fiber woven strip.

[0032] Among them, homogeneous thin strips are thin strips of uniform thickness produced by rolling or drying reconstituted tobacco pulp, with a uniform composition that facilitates stable winding. Composite laminated strips are composed of multiple functional materials such as tobacco layers, moisturizing layers, or flavoring layers, enabling phased release of aerosols or flavor adjustment. Porous structure strips form an internal microporous network through physical foaming or fiber interlacing processes to enhance air permeability, aroma retention capacity, and airflow permeation efficiency during heating. Surface textured strips increase the effective heating area and improve winding adhesion by embossing raised or recessed patterns or grooves. Gradient density strips adjust the density or composition distribution along the length or cross-sectional direction to control aerosol generation kinetics. Flavor-loaded fiber woven strips load tobacco extracts onto a flexible fiber matrix, balancing mechanical strength and high matrix loading.

[0033] In some embodiments of this application, the core 111 is a magnetic induction core, which can sense changes in the magnetic field of the outer magnetic induction coil and generate heat to heat the winding 112.

[0034] The core 111 can generate heat under the influence of the alternating magnetic field produced by the outer magnetic induction coil, thereby achieving efficient and precise heating of the winding component 112. This heating method does not require complex physical contact or external heat conduction; heat can be quickly and evenly transferred from the inside of the core 111 to the tobacco strip. At the same time, since the heat generation is concentrated in the core 111 itself, the thermal impact on the surrounding materials is reduced, the consistency of aerosol release is improved, and the overall system's heating controllability and user experience are enhanced.

[0035] In some embodiments, the magnetic induction coil is arranged around the entire smoke-generating body 100°. The magnetic induction coil has a single-layer or multi-layer solenoid structure.

[0036] In some embodiments of this application, when the core 111 only serves a supporting function, the core 111 may be selected from polymer fibers (such as polylactic acid, cellulose acetate, aramid), ceramics, metals (such as aluminum, stainless steel), carbon materials (such as graphite, carbon fiber), or composite materials. When the core 111 is a magnetic induction core, the material of the core 111 is preferably a ferromagnetic alloy, ferrite, or magnetically conductive stainless steel. In the foregoing embodiments, the core 111 may be configured as a porous, non-hollow structure in the winding member 112 to form airflow channels formed by the porous structure within the winding member 112.

[0037] In some embodiments of this application, such as Figure 3 The smoke generator 100 also includes a heating element 120, which is used to heat the winding member 112 to generate an aerosol. The heating element 120 is arranged around the periphery of a unit 110 along the axial direction of the unit 110.

[0038] In some embodiments of this application, the smoke generator 100 includes multiple groups of monomers 110, each group of monomers 110 includes two or more monomers 110, and the heating element 120 is arranged around the periphery of each group of monomers 110 along the axial direction of the monomers 110.

[0039] In some embodiments of this application, the smoke generator 100 includes a plurality of monomers 110, and the heating element 120 is arranged around all monomers 110 along the axial direction of the monomers 110.

[0040] That is, the smoke generator 100 provided in this application can be a heating element 120 and a core 111 working together to heat the aerosol generating matrix, or the core 111 heating the aerosol generating matrix alone, or the heating element 120 heating the aerosol generating matrix alone, while the core 111 provides a supporting function.

[0041] Various structures employing a heating element 120 circumferentially surrounding the unit 110 offer significant advantages. When the heating element 120 axially surrounds a single unit 110, a group of units 110, or all units 110, this circumferential heating method provides direct, comprehensive, and uniform heat radiation or conduction to the inner winding component 112 from the outside. Compared to single-point or unilateral heating, this design greatly improves heating uniformity and efficiency, ensuring that the aerosol generation matrix in the winding component 112 is synchronously and fully heated along its entire circumference and corresponding length. This not only facilitates rapid and complete aerosol generation, enhancing the immediacy and fullness of the inhalation experience, but also effectively prevents localized overheating or underheating caused by uneven heating. Therefore, while improving aerosol quality consistency, it also contributes to increasing the thermal efficiency and overall operational reliability of the smoke generator 100.

[0042] In some embodiments of this application, the heating element 120 is a metal wire, which is spirally arranged around the periphery of the unit 110.

[0043] In some embodiments of this application, the heating element 120 is a metal mesh, which is arranged around the periphery of the unit 110.

[0044] The design of the heating element 120, which employs a spiral winding of metal wire or a metal mesh surrounding the monomer 110, offers multiple beneficial effects. This structure achieves close contact or near-distance coverage between the heating element and the winding 112 of the monomer 110, thereby establishing an efficient and uniform radial heat transfer path. The spiral structure of the metal wire provides continuous and controllable heating distribution in both the axial and radial directions, while the metal mesh forms a more comprehensive circumferential thermal enclosure. This circumferentially uniform heating ensures that the aerosol generation matrix in the winding 112 is heated more consistently throughout its periphery and thickness direction, effectively promoting rapid, sufficient, and stable aerosol generation and avoiding localized overheating or underheating. Meanwhile, the rapid thermal response characteristics of metallic materials improve heating efficiency, and their stable mechanical structure also helps to maintain the durability and reliability of the smoke generator 100 during manufacturing and use. In particular, for bundled smoke generators 100, the smoke generators 100 can be bundled or limited by spiral winding or metal mesh rings to maintain the bundled product state, which also ensures continuous and long-distance production.

[0045] In some embodiments of this application, the smoke generator 100 is provided with an insertion space for inserting a heating element to heat the smoke generator 100. The insertion space extends along the axial direction of the smoke generator 100, and its cross-sectional shape is adapted to the cross-sectional shape of the heating element to be inserted, such as a circular hole, a rectangular slot, or a polygonal channel. The insertion space can be located on the central axis of the smoke generator 100 or it can be offset.

[0046] By reserving a dedicated insertion channel for the external heating element, this design achieves precise and close contact between the heating element and the aerosol-generating matrix inside the smoke generator 100, thereby establishing an efficient embedded heating path. This heating method allows heat to be transferred directly and rapidly from the inside to the surrounding matrix material, significantly improving heat conduction efficiency and heating uniformity, and contributing to the rapid and complete generation of aerosols. Simultaneously, this structure physically separates the main heating components from the smoke generator 100, facilitating independent control, replacement, or maintenance of the heating element, enhancing the system's modularity and ease of use, and reducing the heat load on the smoke generator 100 itself. This, in turn, improves the overall controllability, safety, and design flexibility of the heating process.

[0047] In some embodiments of this application, the heating element can be a rod-shaped or needle-shaped resistance heating element, such as a slender needle-shaped or rod-shaped structure made of high-temperature resistant metal alloy or ceramic. It can also be a plate-shaped insert heating element, such as a rigid or flexible insert made of metal sheet or ceramic-based thick film heating element.

[0048] In some embodiments of this application, such as Figure 6 Along the radial direction of the core 111, at least two layers of winding members 112 are wound on each individual unit 110, and the at least two layers of winding members 112 are stacked in sequence.

[0049] Through multi-level winding, the aerosol-generating matrix, such as tobacco strips, forms a thicker effective material layer and a more complex internal structure in the radial direction of monomer 110. This not only significantly increases the total matrix area available for heating and gasification but also optimizes the heat transfer and aerosol flow paths through the gaps and contact relationships between layers. When heat is conducted outward from the core 111 or penetrates inward from the external heating element 120, the multi-layer structure helps to distribute heat more evenly and gradually in the radial direction, thereby achieving more thorough and stable heating of the matrix and promoting continuous and abundant aerosol generation. At the same time, this superimposed structure also enhances the overall structural strength and stability of monomer 110, enabling it to maintain its morphological integrity better in subsequent bundling or textile processing, which is beneficial to improving the structural durability and production yield of the final smoke generator 100.

[0050] In some embodiments of this application, along the radial direction of the core 111, at least two winding members 112 are wound on each individual unit 110, and at least two winding members 112 are wound synchronously on the core 111.

[0051] Unlike sequential stacking, synchronous winding allows multiple tobacco strips and other aerosol-generating matrices to be arranged in parallel and tightly around the core 111, forming a composite winding layer. This method enables uniform distribution and tight bonding of the matrix material in the radial cross-section within a single layer. This not only ensures higher integrity and density uniformity of the winding component 112 structure during molding, but also allows heat to diffuse more quickly and consistently to all matrix materials in both the circumferential and radial directions when transferred outward from the core 111 or penetrated inward from the outside. This facilitates more efficient and synchronized heating and aerosol release, improving the consistency of the inhalation response speed and experience. Furthermore, the structure itself possesses excellent radial tensile strength, which helps enhance the morphological stability of the monomer 110 during subsequent processing.

[0052] In some embodiments, such as Figure 6 The core 111 is wound with 2-7 layers of winding material 112. By changing the number of winding layers, the overall thickness of the smoke generator 100 can be adjusted, thereby structurally controlling the total content of the aerosol generation matrix loaded on the smoke generator 100. This design allows smoke generators 100 of different specifications to adapt to different aerosol release requirements, providing a flexible and controllable technical means for product serialization.

[0053] It should be added that, in other embodiments, the core 111 may also have only one layer of winding member 112 wound around it. This is not specifically limited.

[0054] In some embodiments of this application, at least two winding members 112 are wound around the core 111 on each individual unit 110, and the at least two winding members 112 are partially staggered along the axial direction of the core 111.

[0055] Through an axially staggered design, the winding elements 112 are not perfectly aligned, but rather arranged in an alternating pattern on the surface of the core 111. This layout not only increases the uniformity and continuity of the aerosol generation matrix covering the outer surface of the core 111 and reduces heating blind spots, but more importantly, it creates longer airflow channels and richer heat exchange interfaces. When airflow passes through or is heated, the staggered structure guides the airflow to diffuse more fully, thereby improving the efficiency of heat transfer from the core 111 or heating element 120 to the matrix and promoting more effective removal of the generated aerosol. This helps to achieve more complete and stable aerosol generation and release, optimizing the fullness and smoothness of the suction experience. At the same time, this structure also enhances the axial structural toughness and integrity of the unit 110.

[0056] In some embodiments of this application, gaps are formed between different winding members 112 or between winding members 112 and core 111 in the smoke-generating body 100, or gaps are formed between multiple individual units 110, so that the winding members 112 can deform within the smoke-generating body 100 to allow the heating element to be inserted and heat the individual units 110.

[0057] It should be noted that because the core 111 is wrapped with two or more layers of winding material 112, it has a certain thickness, which makes the monomer 110 as a whole deformable. After the monomers 110 are bundled together, they will squeeze and deform each other, thus almost filling the interior of the smoke body 100. There are actually no obvious gaps inside the smoke body 100. In this way, the roundness and hardness of the smoke body 100 can be guaranteed.

[0058] Within the smoke generator 100, gaps are designed and formed between the winding elements 112, between the winding elements 112 and the core 111, and / or between multiple individual units 110. These gaps provide the necessary deformation space for the internal winding elements 112, allowing them to undergo elastic deformation or adaptive displacement when subjected to external pressure. This characteristic enables external heating elements (such as sheet-like or needle-like heating elements) to be inserted into the smoke generator 100 more smoothly and stably, and to form a tight and uniform contact with the individual units 110, especially the winding elements 112, after insertion, thereby establishing an efficient and direct heat transfer path. The existence of gaps not only ensures the smoothness of the insertion process and reduces the risk of damage to the winding elements 112 due to hard friction, but also optimizes the flow and diffusion of hot air during heating, helping to distribute heat more evenly throughout the smoke generator 100, thereby achieving more efficient and complete aerosol generation, and improving the overall heating reliability and ease of product use.

[0059] In some embodiments of this application, such as Figure 1-2 and Figure 4-6 The smoke generator 100 also includes a covering 130, which covers the periphery of all monomers 110 to fix all monomers 110.

[0060] The covering 130, acting as an external, integral constraint layer, tightly and securely integrates multiple independent units 110 together to form a structurally complete and unified smoke generator 100. This not only effectively prevents the individual units 110 from loosening, shifting, or deforming during subsequent processing, transportation, or use, ensuring the long-term stability of the internal structure of the smoke generator 100, but also provides additional mechanical protection through external wrapping, enhancing the overall durability of the product.

[0061] In some embodiments of this application, the covering 130 includes covering paper, covering filaments, or covering mesh. The covering paper covers the periphery of all monomers 110, and the covering filaments or covering mesh cover the periphery of all monomers 110 for heating the monomers 110.

[0062] The covering paper can be selected from cigarette paper, parchment paper, or composite paper coated with a heat-insulating coating. The covering wire or covering mesh can be selected from nickel-chromium alloy wire, stainless steel wire, iron-chromium-aluminum wire, or their woven fabric, and an insulating layer can be provided on its surface.

[0063] When using covering paper, it primarily serves a good fixing and shaping function, tightly integrating all monomers 110 to ensure the structural stability of the smoke-generating body 100, facilitating subsequent processing and use. When using covering filaments or covering mesh, in addition to achieving stable bundling, they can also function directly as heating elements—the covering filaments or mesh can uniformly and comprehensively wrap all monomers 110, thereby transferring heat from the outer periphery to the interior when energized or induction heated, achieving more uniform and efficient heating of the aerosol-generating matrix. Both methods improve the structural integrity, production convenience, and consistency of heating performance of the smoke-generating body 100.

[0064] like Figure 7 This application also provides an aerosol generating article 200, which includes a mouthpiece 210, a cooling body and the aforementioned smoke generator 100 arranged sequentially along the axial direction.

[0065] Applying the aforementioned smoke-generating body 100 to the aerosol-generating product 200 offers several advantages. Functionally, the continuous aerosol-generating matrix provides stable and sufficient aerosol release, which, in conjunction with the cooling section and mouthpiece 210, enhances the user's vaping experience. In terms of durability, the structural integrity of the continuous aerosol-generating matrix within the smoke-generating body 100 ensures the product's resistance to mechanical stress during assembly, transportation, and use, reducing the likelihood of functional failure due to internal component breakage or deformation. From a production and quality perspective, the continuous shape of the core component (winding element 112) of the smoke-generating body 100 significantly reduces breakage rates and uneven distribution during production. This directly improves the overall assembly yield and batch-to-batch consistency, making the manufacturing process from component to finished product more reliable and efficient.

[0066] In some embodiments of this application, the aerosol generating article 200 further includes a plug 230, which is disposed at the end of the smoke-generating body 100 away from the cooling body.

[0067] A plug 230 is provided at the end of the smoke-generating body 100 of the aerosol-generating product 200, mainly serving to seal and prevent contamination, axially solidify, and guide airflow. It protects the internal aerosol-generating matrix from moisture contamination, maintains structural stability, and optimizes the heating airflow path, thereby improving product shelf life, reliability, and aerosol generation effect.

[0068] This application also provides a heated non-combustible system, which includes a heated non-combustible device, the aforementioned smoke generator 100 or the aforementioned aerosol generating article 200.

[0069] In some embodiments of this application, the smoke generator 100 can be installed on a heating non-combustion device and heated by the heating non-combustion device.

[0070] In some embodiments of this application, the aerosol generating article 200 can be installed on a heat-not-burning device and heated by the heat-not-burning device.

[0071] In use, the user inserts the aerosol generating product 200 into the heating chamber of the heated non-combustible device. The heated non-combustible device heats the magnetic induction core by providing an alternating magnetic field to the core through its internal magnetic induction coil, or by supplying power to the heating element 120 through contact electrodes, or by pushing the heating element into the insertion space of the smoke-generating body 100. The aerosol generating matrix produces aerosol after heating, and the airflow passes sequentially through the smoke-generating body 100 and the cooling body, finally being inhaled by the user through the mouthpiece 210.
