Description

Technical Field

[0001] This utility model belongs to the field of new tobacco technology, and specifically relates to a capsule-shaped electromagnetic induction heating non-combustible tobacco cartridge. Background Technology

[0002] Electronic atomization devices are gaining increasing popularity worldwide as an alternative to traditional cigarettes. Existing heated tobacco products (HTPs) primarily generate aerosols by heating tobacco sheets or herbal granules, but these devices suffer from uneven heating and a tendency to produce a pasty taste.

[0003] To address these issues, some companies, including the applicant, have developed heated tobacco cartridges using electromagnetic induction heating technology. These cartridges typically contain an electromagnetic induction magnetic heating sensor and are filled with tobacco sheets or granules containing an aerosol-generating matrix. However, existing electromagnetic induction heated tobacco cartridges have the following shortcomings: 1. The limited contact area between the magnetic heating sensor and the aerosol-generating matrix leads to poor heat conduction in localized areas, resulting in insufficient carbonization of the aerosol-generating matrix; 2. The molding, filling, and magnetic heating sensor implantation processes for the aerosol-generating matrix are complex, resulting in low yields and high production costs; 3. Due to the stringent requirements on materials, structure, and form in heated tobacco applications, the selection range for aerosol-generating matrices, magnetic heating sensors, and tobacco tubes is limited, making it difficult to achieve simplified production methods and efficient heating effects.

[0004] Therefore, there is an urgent need to design innovative electromagnetic induction heating non-combustible tobacco cartridges to solve these problems. Utility Model Content

[0005] To address the aforementioned problems in the prior art, this invention provides a capsule-type electromagnetic induction heating non-combustible tobacco cartridge. An aerosol generating matrix and a magnetic heating sensor are encapsulated within a capsule, which is housed within the cartridge shell. During use, the device generates a high-frequency alternating electromagnetic field, inducing eddy currents in the magnetic heating sensor, carbonizing the aerosol generating matrix. The resulting aerosol escapes through vents on the capsule shell for the user's consumption. This tobacco cartridge offers advantages such as good heating uniformity, high design flexibility, and good product stability.

[0006] The specific solution is: a capsule-type electromagnetic induction heating non-combustible tobacco cartridge, including a cartridge shell and a capsule contained therein, the capsule including a capsule shell, an aerosol generating matrix and a magnetic heating sensor contained in the capsule shell; the capsule shell is provided with at least one vent hole.

[0007] Preferably, the capsule shell is made of a material that can withstand at least 300°C, and the size of the vent is no greater than 900 μm.

[0008] Preferably, the capsule consists of a capsule cap and a capsule body that are fitted together, with the capsule cap and capsule body coaxially fitted together to form an accommodating space in which the aerosol generating matrix and the magnetic heating sensor are accommodated, and the capsule cap and / or capsule body are provided with vent holes.

[0009] Preferably, the magnetic heating sensor is a magnetic metal powder or magnetic metal fragment distributed in the aerosol generating matrix, and the size of the magnetic metal powder or magnetic metal fragment is larger than the size of the vent hole.

[0010] Preferably, the magnetic heating sensor is a magnetic metal foil attached to the inner wall of the capsule shell, and the vent hole penetrates the capsule shell and the magnetic metal foil.

[0011] Preferably, the magnetic heating sensor is one or more magnetic metal sheets disposed inside the capsule shell.

[0012] Preferably, the aerosol generating matrix is ​​granular, and the magnetic heating sensor is a magnetic film wrapped around the surface of the aerosol generating matrix, with the size of the composite particle formed by the two being larger than the size of the vent hole; or, the magnetic heating sensor is powdered, and the aerosol generating matrix is ​​wrapped around the surface of the magnetic heating sensor, with the size of the composite particle formed by the two being larger than the size of the vent hole.

[0013] Preferably, the aerosol generating matrix is ​​columnar, and the magnetic heating sensor is a magnetic metal strip, which is wound around the side of the columnar aerosol generating matrix; the magnetic metal strip is one or more strips, which extend axially along the side of the aerosol generating matrix, or extend spirally.

[0014] Preferably, the inner wall of the capsule shell is provided with a metal foil magnetic heating sensor.

[0015] Preferably, the number of capsules in the same cartridge shell is two or more.

[0016] Compared with the prior art, the beneficial effects of this utility model include at least the following:

[0017] 1. High heating uniformity of the aerosol generating matrix. The aerosol generating matrix is ​​encapsulated within a capsule, and the capsule is heated using electromagnetic induction technology. The aerosol generating matrix and magnetic heating sensors are evenly distributed within the capsule, resulting in excellent heating uniformity. This effectively avoids localized overheating, improving aerosol generation efficiency and taste consistency. Furthermore, the uniform heating method reduces localized over-carbonization, effectively minimizing the formation of harmful substances and enhancing product safety.

[0018] 2. High flexibility in cartridge design. Encapsulating the aerosol generating matrix and magnetic heating sensor within the capsule expands the range of forms that can be chosen for both, and eliminates the need for separate molding and filling processes for the aerosol generating matrix segment, as well as the implantation process for the magnetic heating sensor. This provides greater flexibility in product structure and material design, allowing for the selection of appropriate solutions based on different needs.

[0019] 3. Excellent cartridge stability. The capsule shell, made of high-temperature resistant materials, effectively protects the aerosol-generating matrix, preventing it from contacting the external environment and preventing leakage and flavor escape, thus improving product stability and lifespan.

[0020] 4. Magnetic heating sensors are available in various forms. Different forms of magnetic heating sensors, combined with different aerosol generating matrices, will produce different effects, as illustrated below:

[0021] 4.1 Form 1: The magnetic heating sensor is a magnetic metal powder or fragment dispersed in the gaps between the particulate aerosol generating matrix. This form employs a discrete, distributed heating mode. The magnetic heating sensor has a large contact area with the aerosol generating matrix, enabling rapid and uniform carbonization and releasing a rich aerosol.

[0022] 4.2 Form Two: The magnetic heating sensor is a thin magnetic metal film wrapped around the surface of the particulate aerosol-generating matrix. This wrapping configuration forms numerous composite particles containing the aerosol matrix, creating a distributed, localized, circumferential heating pattern. This allows for more efficient heat transfer to the aerosol-generating matrix, improving carbonization efficiency. The thin-film magnetic heating sensor tightly wraps around the surface of the aerosol matrix particles, increasing the heating contact area and enabling more thorough carbonization of the aerosol-generating matrix. Furthermore, this fully wrapped configuration effectively prevents the escape of volatile components, enhancing the fragrance retention and aroma retention effect during storage.

[0023] 4.3. Form 3: The magnetic heating sensor is a magnetic metal powder or fragment encapsulated within the aerosol-generating matrix. This encapsulation configuration forms numerous composite particles containing sensors, constituting a distributed, locally centered heating mode. Each composite particle has an independent magnetic heating sensor, enabling more efficient heat transfer to the aerosol-generating matrix and improving carbonization efficiency.

[0024] 4.4 Form Four: The magnetic heating sensor is a magnetic metal foil attached to the inner wall of the capsule shell. This form employs a holistic, circumferential heating method, resulting in excellent heating uniformity. This ensures that heat is transferred over a large area and rapidly to the aerosol-generating matrix, improving carbonization efficiency and aerosol quality. The assembly process is simple; the metal foil magnetic heating sensor can be bonded to the capsule shell through calendering or deposition, then integrally molded and vented, simplifying the production process.

[0025] 4.5 Form Five: The magnetic heating sensor is a magnetic metal sheet located in the central region inside the capsule shell. This form adopts a central heating mode. When the cartridge is located in the induction coil of the electronic atomizing device, because the magnetic flux distribution is concentrated in the central axis region of the coil, the magnetic heating sensor located in the center of the capsule can form a stronger and more stable coupling with the magnetic field, thus maximizing the utilization of the magnetic field and achieving higher heating efficiency. In addition, this configuration has the advantage of concentrating heat on the aerosol generation matrix, reducing the thermal impact on the capsule shell and cartridge shell, thereby improving product safety.

[0026] 4.6 Form Six: The magnetic heating sensor is a magnetic metal wire, and the aerosol generating matrix is ​​a filament or thread, which are woven together to form a rope-like structure. This form employs a rope-like random heating mode. The close integration of the magnetic heating sensor and the aerosol generating matrix results in a large contact area, high heat transfer efficiency, and the ability to achieve a thorough and uniform heating and carbonization effect. The textile technology for creating this rope is relatively mature, and the metal drawing process and the preparation process of the aerosol generating matrix carrier fiber thread are easily scalable for mass production.

[0027] 4.7 Form Seven: The magnetic heating sensor is a thin magnetic metal strip, and the aerosol generating matrix is ​​columnar. The magnetic metal strip is wound around the side of the columnar aerosol generating matrix. This form uses a magnetic strip for circumferential localized heating. The magnetic heating sensor and the aerosol generating matrix make localized contact in a spiral manner, which can prevent localized over-carbonization. This winding process is relatively simple and easy to insert into the capsule. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1

[0036] This embodiment provides a capsule-type electromagnetic induction heating non-combustible tobacco cartridge, comprising: a cartridge shell and a capsule, wherein the capsule is a sphere-like object containing discretely distributed particles (or at least has a circular cross-section).

[0037] like Figure 1 As shown, the cartridge shell adopts a hollow tubular design with an internal cavity for accommodating the capsule. To withstand the high temperatures during the heating process, the cartridge shell is made of a high-temperature resistant material. In this embodiment, the cartridge shell is made of a stiff, thick paper tube formed by cross-rolling ordinary paper and bonding it with glue. The example uses two capsules; in other embodiments, the number can be any.

[0038] like Figure 2 As shown, the capsule is disposed within the receiving cavity of the cartridge shell, and the capsule includes the following components: capsule shell 1, aerosol generating matrix 2, and magnetic heating sensor 3.

[0039] The capsule shell 1 has a spherical design and is made of high-temperature resistant polyimide material. It can also be made of materials such as polytetrafluoroethylene, aramid, modified fire-resistant paper (such as hydroxyapatite compounds), and other plant fibers that can withstand the high temperature, and can withstand 300°C for at least 10 minutes.

[0040] To ensure the smooth passage of aerosols and airflow, the capsule shell 1 is provided with multiple vent holes 11 with a diameter of 50 μm. This size is smaller than the minimum particle size of the internal particles, effectively preventing leakage. The internal particles include powder with a diameter of a few micrometers that is indistinguishable to the naked eye, as well as particles with a diameter of a few millimeters that are distinguishable to the naked eye.

[0041] The aerosol generating matrix 2 is granular and is made from a mixture of tobacco plants, a fogging agent, a gelling agent, a flavoring agent, and a preservative. The aerosol generating matrix particles have an average particle size of 300 μm and are filled inside the capsule shell 1.

[0042] The magnetic heating sensor 3 is in powder form and is made of a 4J42 soft magnetic alloy material with strong magnetism. The average particle size of the magnetic heating sensor 3 powder is 100 μm, and it is discretely distributed in the gaps between the particles of the aerosol generation matrix 2.

[0043] This embodiment employs a discrete distributed heating mode. Magnetic heating sensors 3 are uniformly distributed within the aerosol generation matrix 2, resulting in a large contact area between them, which enables rapid and uniform carbonization and releases a rich aerosol.

[0044] The manufacturing process for the spherical capsule shell is mature and facilitates large-scale production. The encapsulation process of the granular aerosol generating matrix 2 and the powdered magnetic heating sensor 3 within the capsule shell is simple and easily scalable for mass production. The plant material granulation process for the aerosol generating matrix 2 and the metal powder spraying process for the magnetic heating sensor 3 are mature and reliable.

[0045] This embodiment also includes similar alternative implementation methods, including:

[0046] In addition to using the pre-formed rigid thick paper tube mentioned above, the cartridge shell can also use a post-formed soft thin paper tube, which is made by rolling and bonding the capsule and other components (such as the filter tip, cooling components, etc.) together in parallel using cigarette paper. The cartridge shell can also be made of high-temperature resistant plastics, plant fibers, and other materials, and is formed by molding.

[0047] The capsule shell 1 can be designed into other shapes that are easy to manufacture and assemble, such as basic geometric shapes like disc, ring, olive, cylinder, tube, teardrop, gourd, eggplant, and fish, or similar shapes, according to actual needs.

[0048] The vent 11 in the capsule shell 1 can be adjusted according to the minimum particle size of the internal material, and its equivalent diameter range is recommended to be 1-900 μm. The design of multiple vent 11 is beneficial for improving ventilation and reducing suction resistance. The magnetic heating sensor 3 is magnetic metal powder or magnetic metal fragments distributed in the aerosol generating matrix 2, and the size of the magnetic metal powder or magnetic metal fragments is slightly larger than the vent size to ensure no leakage.

[0049] The aerosol generating matrix 2 can be selected in other shapes that are easy to fill and wrap, such as blocks or sheets, according to actual needs.

[0050] The magnetic heating sensor 3 can be configured in various shapes to facilitate uniform mixing into the aerosol generation matrix 2, including powder, fragments, etc.

[0051] Example 2

[0052] This embodiment provides a capsule-shaped electromagnetic induction heating non-combustible tobacco cartridge, whose external structure is basically the same as that of Embodiment 1. The main difference lies in the design of the magnetic heating sensor 3 inside the capsule, as detailed below. Figure 3 As shown, its structural features are that the aerosol generating matrix 2 is in the form of spherical particles, and each particle is coated with a magnetic heating sensor 3 in the form of a thin film. After the two are wrapped together, the size of the composite particle is larger than the size of the air vent.

[0053] In this embodiment, the magnetic heating sensor 3 film is made of nickel material with a thickness of 2-3 μm, which encapsulates each aerosol generating matrix 2 particle to form a "microcapsule" structure.

[0054] This embodiment employs localized circumferential heating, which more effectively transfers heat to the aerosol-generating matrix, improving carbonization efficiency. Simultaneously, it effectively prevents the escape of volatile components, enhancing the fragrance retention and aroma retention of the product during storage.

[0055] This embodiment also includes similar alternative implementations: the magnetic heating sensor 3 is a powder or fragment, and the aerosol generating matrix 2 is a film wrapped around the surface of the magnetic heating sensor 3, forming a distributed localized central heating mode. The size of the composite particles formed by the two is larger than the size of the vent holes, which can more effectively transfer heat to the aerosol generating matrix and improve carbonization efficiency.

[0056] Example 3

[0057] This embodiment provides a capsule-shaped electromagnetic induction heating non-combustible tobacco cartridge, whose external structure is basically the same as that of Embodiment 1. The main difference lies in the design and placement of the magnetic heating sensor 3, as detailed below. Figure 4 As shown, its structural features are that the capsule includes a metal foil magnetic heating sensor 3 which is fixed to the inner wall of the capsule shell 1 by means of adhesion, compression or other methods.

[0058] The magnetic metal foil is made of 1J50 soft magnetic alloy material with a thickness of 30μm. It forms an integrated structure with the capsule shell 1 and completely encapsulates the aerosol generation matrix 2 inside. To ensure the smooth escape of the aerosol, multiple through-holes 11 with a diameter of 50μm are provided on the integrated structure.

[0059] This embodiment employs a holistic, circumferential heating method, which ensures good heating uniformity and guarantees that heat is transferred over a large area and quickly to the aerosol generation matrix 2, thereby improving carbonization efficiency and aerosol quality. This method also simplifies the assembly process; the magnetic metal foil magnetic heating sensor 3 can be bonded to the capsule shell 1 via calendering or deposition, and then integrally molded with ventilation holes 11, simplifying the production process.

[0060] This embodiment also includes similar alternative implementation methods:

[0061] In addition to using heat-resistant materials that do not participate in chemical reactions, the capsule shell 1 can also be made of fibrous materials containing tobacco plants, nicotine, or nicotine salts. This design allows the capsule shell 1 to partially decompose during heating, releasing additional tobacco components and providing users with an experience closer to that of traditional cigarettes.

[0062] Example 4

[0063] This embodiment provides a capsule-type electromagnetic induction heating non-combustible tobacco cartridge, the capsule structure of which is as follows: Figure 5 As shown, its structural feature is that the capsule is a columnar body containing a central plate-type magnetic heating sensor 3 inside.

[0064] In this embodiment, the capsule shell 1 adopts a generally cylindrical design, consisting of a coaxial capsule cap and a capsule body that can be fitted together. Both the capsule cap and capsule body have an open end, a closed end, and a sidewall. The sidewall is 100 μm thick, and the closed end and the sidewall together form the complete capsule shell 1. To ensure the smooth escape of the aerosol, the capsule cap and / or capsule body are provided with several vent holes 11, each with a diameter of 50 μm.

[0065] Unlike the three embodiments mentioned above, in this embodiment, the aerosol generating matrix 2 is made of a mixture of stem-like and fragmented tobacco shreds, which is randomly surrounded around the magnetic heating sensor 3 and fills the inside of the capsule shell 1.

[0066] In this embodiment, the magnetic heating sensor 3 adopts a thin sheet metal design and is centrally located in the inner part of the capsule. Its material is magnetic stainless steel SUS410 (1Cr13) with a thickness of 80μm.

[0067] This embodiment employs a central heating mode. When the cartridge is located within the induction coil of the electronic atomizing device, the magnetic flux is concentrated in the central axis region of the coil. This allows the magnetic heating sensor 3, located at the center of the capsule, to achieve a stronger and more stable coupling with the magnetic field, maximizing the utilization of the magnetic field and thus obtaining higher heating efficiency. Furthermore, this configuration has the advantage of concentrating heat on the aerosol-generating matrix 2, reducing the thermal impact on the capsule shell 1 and the cartridge shell, and improving product safety.

[0068] This embodiment also includes similar alternative implementations: in addition to the single-layer structure and single metal described in this embodiment, the magnetic heating sensor 3 can also adopt a multi-layer structure with a composite structure. For example, multiple metal materials such as iron, cobalt, nickel, chromium, zinc, silver, copper, aluminum, 4J29 Invar alloy, stainless steel 410, and various soft magnetic alloys can be combined and a protective coating, such as a chromium coating, can be applied to the surface to form a composite sensor. This configuration is more conducive to realizing multiple functions such as anti-counterfeiting identification, temperature measurement and control, protection response, and corrosion and rust prevention.

[0069] The number of magnetic metal sheets is configured as one or more, such as three or five sheets, and they are evenly distributed in the aerosol generation matrix 2 to achieve sufficient heating.

[0070] Example 5

[0071] This embodiment provides a capsule-shaped electromagnetic induction heating non-combustible tobacco cartridge, whose structure is basically the same as that of Embodiment 4. The main difference lies in the configuration of the aerosol generating matrix 2 and the magnetic heating sensor 3 inside the capsule. Figure 6 As shown, its structural features are as follows: the internal aerosol generating matrix 2 is a columnar strip, and the magnetic heating sensor 3 is a thin metal strip, which is spirally wound around the side of the columnar strip.

[0072] In this embodiment, the aerosol generating matrix 2 is a loosely structured strip with a diameter of 6 mm.

[0073] In this embodiment, the magnetic heating sensor 3 is a magnetic metal strip with a thickness of 50 μm and a width of 1,000 μm. The metal strip is wound around the side surface of the columnar aerosol generating matrix 2 to form a strip, which is then cut into smoke-generating segments of appropriate length. One smoke-generating segment is then encapsulated inside a capsule. Here, the height of the columnar smoke-generating segment is 10 mm.

[0074] This embodiment employs a thin strip-shaped heating sensor for circumferential localized heating. The magnetic heating sensor 3 and the aerosol generating matrix 2 are in localized contact via a spiral pattern, which prevents excessive localized carbonization. This winding process is relatively simple and facilitates insertion into the capsule.

[0075] In other applications, a thin strip of magnetic heating sensor 3 is wound around the side of a columnar aerosol generating matrix 2 and extends axially, tightly embedding itself into the surface of the aerosol generating matrix 2 to achieve both fixation and heating functions.

[0076] Based on the aforementioned five specific embodiments, when the cartridge is inserted into the electronic atomizing device, the electromagnetic induction coil in the device generates a high-frequency alternating magnetic field. This alternating magnetic field passes through the capsule shell, inducing eddy currents in the magnetic heating sensor 3. The Joule heating effect of the eddy currents is used to heat the aerosol generation matrix 2, carbonizing it and producing an aerosol. The aerosol escapes through the vent on the capsule shell 1 for the user's use.

[0077] In practice, more than two capsules can be configured inside the same cartridge (i.e., cartridge shell) to achieve additional functions such as larger vapor production, longer usage time, or flavor adjustment.
