Description

Technical Field

[0001] This invention relates to the field of aerosol generation technology, and more particularly to aerosol products and aerosol generation systems. Background Technology

[0002] Electromagnetic induction heating is one of the mainstream heating methods in heated non-combustible aerosol generators. An aerosol generator typically includes an electronic circuit system and an induction coil. During use, the aerosol product is placed in a preset position within the generator. The electronic circuit system generates high-frequency resonance, driving the induction coil to generate an alternating magnetic field. Magnetic sensors in the aerosol product generate eddy currents and heat up within this alternating magnetic field, thus heating the aerosol-generating matrix.

[0003] In existing technologies, the magnetic characteristics exhibited by magnetic sensors relative to fixed-mode alternating magnetic fields often differ significantly due to various factors, including: variations in material and dimensional consistency during manufacturing, positional accuracy during assembly into aerosol products, positional changes during transportation, improper placement during use, and the interference of temperature fluctuations on magnetic strength. These differences affect the coupling effect between the magnetic sensor and the alternating magnetic field, thereby interfering with the accuracy of aerosol product identification, temperature control, and other functional controls. This can lead to misjudgments in electronic circuit systems, resulting in inappropriate operations or even abnormal shutdowns, impacting user experience.

[0004] Meanwhile, related technologies use magnetic fillers added to the outside of aerosol products to improve recognition performance, but the magnetic parameters of the fillers (e.g., particle size, particle diameter, magnetism) are unconstrained, resulting in poor magnetic reinforcement and low recognition pass rate of aerosol products.

[0005] Currently, no effective solution has been proposed to address the problem of misjudgment, malfunction, and negative impact on user experience caused by significant differences in magnetic characteristics in aerosol generators. Summary of the Invention

[0006] In view of this, it is necessary to provide an aerosol product and an aerosol generation system to solve at least some of the problems in the aforementioned related technologies.

[0007] In a first aspect, the present invention provides a technical solution as follows: an aerosol product comprising a smoke-generating body, a single magnetic sensor, a carrier, and magnetic particles, wherein the single magnetic sensor is embedded in the smoke-generating body, the smoke-generating body is configured as a combination of a smoke-generating matrix and the carrier, the single magnetic sensor is capable of generating heat energy in an alternating magnetic field to heat the smoke-generating matrix, the carrier is arranged radially outward of the smoke-generating matrix, the magnetic particles are dispersed in a predetermined region of the carrier, and the carrier constrains the magnetic particles radially outward of the smoke-generating matrix, the specific saturation magnetization of the magnetic particles is 5~90 ​​emu / g, and the longitudinal coverage ratio of the predetermined region to the single magnetic sensor is 0.5-1.

[0008] In some embodiments, the carrier is a smoke-generating medium, and the magnetic particles are placed on the carrier by pre-addition or post-addition.

[0009] In some embodiments, the carrier and the smoke-generating matrix are smoke-generating sheets.

[0010] In some embodiments, the carrier is an adhesive medium, and the magnetic particles are mixed with the carrier and then cover the outer peripheral surface of the smoking matrix.

[0011] In some embodiments, the smoke generator is surrounded by packaging paper, and the carrier is placed between the smoke generator and the packaging paper.

[0012] In some embodiments, the magnetic particles have an average particle size of 1~50000 nm; and / or The magnetic particles have a positive temperature resistivity; and / or The Curie temperature of the single magnetic sensor is 300~800℃; and / or The Curie temperature of the magnetic particles is 200~1100℃; and / or The specific saturation magnetization of the magnetic particles is 50~90 emu / g.

[0013] In some embodiments, the mass ratio of the magnetic particle to the single magnetic receptor is (0.3~3):1, and / or the mass of the magnetic particle is 6~150mg.

[0014] In some embodiments, the magnetic particles are made of at least one of the following materials: elemental iron, elemental nickel, elemental cobalt, ferroalloys, nickel alloys, cobalt alloys, iron oxides, cobalt oxides, nickel oxides, ferrites, iron-based / cobalt-based / nickel-based nanocrystalline soft magnetic alloys, permalloys, composite magnetic alloy materials, modified graphite, and modified graphene. The single magnetic sensor is made of at least one of the following materials: elemental iron, elemental nickel, elemental cobalt, ferroalloys, nickel alloys, cobalt alloys, Tenets alloys, permalloys, iron-aluminum alloys, iron-silicon-aluminum alloys, iron-chromium-aluminum alloys, iron-cobalt alloys, nickel-chromium alloys, Sendastel alloys, iron-based / nickel-based / cobalt-based amorphous alloys, neodymium-iron-boron alloys, samarium-cobalt alloys, aluminum-nickel-cobalt alloys, iron-chromium-cobalt alloys, silicon steel, and magnetic stainless steel.

[0015] In some embodiments, a plug is also provided on one side of the smoke-generating body in the axial direction, the plug comprising a matrix and the magnetic particles dispersed in the matrix.

[0016] Secondly, the present invention also provides the following technical solution: an aerosol generation system, comprising an aerosol product and a magnetic induction heating device for heating the aerosol product, wherein the aerosol product includes the aerosol product described in the first aspect.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The aerosol product and aerosol generation system of this application configure the smoke-generating body as a collection of smoke-generating matrix and carrier, and set magnetic particles on the radially outer side of the smoke-generating matrix, and embed a single magnetic sensor inside the smoke-generating matrix. By utilizing the differences in position, shape and size, and magnetic characteristics, the two work together to effectively compensate for the inconsistency and instability of the magnetic characteristics of the single magnetic sensor caused by factors such as its own material, size, assembly, and usage position, thereby improving the overall magnetic characteristics of the aerosol product and enhancing its coupling effect with the alternating magnetic field. As a result, the accuracy of aerosol product identification, the speed and precision of temperature control of the aerosol generating device can be improved, and the control performance of other related functions can be optimized, reducing the misjudgment of the electronic circuit system and significantly improving the user experience. By adopting the method of covering the magnetic particles with the single magnetic sensor, the magnetic particles act on the single magnetic sensor, with a concentration of 5~90 ​​emu / g. The specific saturation magnetization range can fully compensate for the overall magnetic signal of the product and improve the recognition pass rate of the equipment, while preventing the magnetic field from being too strong and taking over the dominant position of the alternating magnetic field coupling. This ensures that the single internal magnetic sensor undertakes the main eddy current heating function, achieving an ideal heating structure with internal heat and external cold.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] It should be noted that when a component is said to be "mounted on" another component, it can be directly mounted on the other component or may be interspersed with a component. When a component is said to be "set on" another component, it can be directly set on the other component or may be interspersed with a component. When a component is said to be "fixed to" another component, it can be directly fixed to the other component or may be interspersed with a component.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] The technical problem that this application aims to solve is described below: In related technologies, various common errors can easily occur during the preparation and processing of magnetic sensors, the assembly of aerosol products, the transportation of aerosol products, and the use of aerosol products by consumers. These errors alter the magnetic characteristics of the aerosol products, ultimately affecting the coupling effect between the magnetic sensors and the alternating magnetic field. Consequently, they interfere with the accuracy of aerosol product identification, temperature control, and other functional controls, leading to misjudgments in the electronic circuit system, inappropriate operations, or even abnormal shutdowns, thus impacting the user experience.

[0023] For example, material segregation during the smelting process can lead to uneven material distribution in the magnetic sensor, resulting in significant differences in the magnetic characteristics of multiple magnetic sensors produced in the same batch. Alternatively, during rolling or cutting, the thickness or length of the finished product may be smaller than expected, resulting in weaker magnetic strength in the magnetic sensor. Furthermore, when embedded in the smoke-generating matrix, if the magnetic sensor is not placed in the predetermined circumferential and / or radial position, deviating completely or partially from the strong magnetic field region of the alternating magnetic field, it weakens its coupling strength and stability with the induction coil. Additionally, during the transportation of aerosol products, the relative position of the smoke-generating matrix and the magnetic sensor may shift due to external mechanical stress, causing changes in the magnetic characteristics of the aerosol product. Finally, if the user does not insert the aerosol product into the intended position in the induction coil when assembling the aerosol generator, it can affect the heating effect or even cause the device to malfunction.

[0024] One typical phenomenon caused by the above-mentioned problem is that the magnetic strength of certain aerosol products is relatively weak. When they are inserted into the aerosol generating device, the induction coil detects a weak magnetic signal. After comparing it with the preset threshold conditions in the control system program, the electronic circuit system mistakenly believes that the aerosol product contains an incorrect magnetic sensor or that an abnormality has occurred. It then shuts down the device, making it impossible for the heating process to continue and the suction process to be completed.

[0025] Even when existing technologies attempt to improve magnetic signals by adding magnetic fillers to the outside of packaging, there are no systematic constraints on the material, particle size, and magnetization intensity of the magnetic particles: the particle size is not controlled, which can easily lead to coating delamination and local agglomeration; the magnetization intensity is not limited to a certain range, and if the magnetic moment of the magnetic powder is too high, it will compete for the magnetic field coupling weight of the main sensor, while if it is too low, the reinforcement effect will be weak; the magnetic domains of general magnetic fillers are randomly arranged, and the magnetic signal dispersion between batches is large, which cannot stably compensate for the performance fluctuations of a single magnetic sensor.

[0026] To solve the above problems, refer to Figures 1 to 9 This application provides an aerosol product including a smoke generator 100, a single magnetic sensor 200, a carrier 300, and magnetic particles 400. The single magnetic sensor 200 is embedded in the smoke generator 100, which is configured as an assembly of a smoke-generating matrix 500 and a carrier 300. The single magnetic sensor 200 can generate heat energy in an alternating magnetic field to heat the smoke-generating matrix 500. The carrier 300 is arranged radially outside the smoke-generating matrix 500. The magnetic particles 400 are dispersed in a predetermined area of ​​the carrier 300, and the carrier 300 constrains the magnetic particles 400 radially outside the smoke-generating matrix 500. The magnetic particles 400 are used to improve the pass rate of the aerosol product being recognized by the aerosol generating device and to enhance its overall magnetic strength.

[0027] For the smoke-generating body 100 to be configured as a combination of a smoke-generating matrix 500 and a carrier 300, it includes at least the following two configurations: one is, refer to Figure 3 , Figure 4 , Figure 12 , Figure 13 and Figure 14 The carrier 300 can be positioned radially outward from the smoke-generating matrix 500, and the magnetic particles 400 can be dispersed on the carrier 300 using a preset processing method, such as pre-addition or post-addition; secondly, refer to Figure 5 A carrier 300 can be provided on the outer surface of the outermost smoke-generating matrix unit (e.g., smoke-generating sheet 600), and magnetic particles 400 can be placed on the carrier 300 according to a preset processing method, thereby forming a ring of carrier 300 and a ring of magnetic particles 400 on the entire outer side of the smoke-generating matrix 500.

[0028] Regarding the setting of the preset area, the longitudinal coverage ratio between the preset area and the single magnetic sensor 200 can be set to 0.5-1. Optionally, the longitudinal coverage ratio between the preset area and the single magnetic sensor can be one of 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, etc. If the longitudinal coverage ratio is less than 0.5, the magnetic strength of the magnetic particles 400 is insufficient, and there is magnetic leakage at both ends of the single magnetic sensor 200, reducing the recognition and enhancement effect. Since the carrier 300 and the smoke-generating matrix 500 together form the smoke-generating body 100, and the single magnetic sensor 200 is inserted into the smoke-generating body 100, the coverage area of ​​the preset area will not exceed the smoke-generating body 100 itself. Therefore, the maximum longitudinal coverage ratio does not exceed 1.0. It is understandable that the larger the longitudinal coverage ratio, the larger the proportion of unloaded magnetic resistance, which will reduce the magnetic flux of the single magnetic sensor 200, reduce the heating effect of the single magnetic sensor 200, and affect the use of the product.

[0029] In this embodiment, the longitudinal coverage ratio is defined as the longitudinal length ratio of a single magnetic sensor covered by a preset area. It can be understood that the magnetic particles 400 in the preset area actually have an effect on the single magnetic sensor 200, so the alignment should be between the magnetic particles 400 and the single magnetic sensor 200.

[0030] Regarding the magnetic emphasis of the magnetic particles 400, in this embodiment of the application, the specific saturation magnetization of the magnetic particles 400 is limited to 5~90 ​​emu / g, preferably 50~90 emu / g.

[0031] In this application, the unit of specific saturation magnetization is emu / g, which characterizes the total magnetic moment of a unit mass of magnetic particles in saturation. In this embodiment, the specific saturation magnetization of the magnetic particles is limited to 5~90 ​​emu / g. When the specific saturation magnetization is less than 5 emu / g, the magnetic reinforcement effect of the magnetic particles is weak and cannot compensate for the magnetic fluctuations caused by the material and assembly of a single magnetic sensor. The cigarette corresponding to the aerosol product is prone to equipment recognition failure. When the specific saturation magnetization is greater than 90 emu / g, the magnetic flux of the external magnetic particles is too high, diverting the energy of the alternating magnetic field, weakening the eddy current heating power of the internal single magnetic sensor, and reducing the heating rate. By using magnetic particles with a specific saturation magnetization in the range of 5~90 ​​emu / g, the overall magnetic signal of the aerosol product can be improved and the recognition pass rate can be increased, while ensuring that the internal single magnetic sensor acts as the main heating carrier, thus balancing recognition stability and heating efficiency.

[0032] In this application, the magnetic particles 400 of the materials used correspond to a specific saturation magnetization range of 5~90 ​​emu / g. For example, the specific saturation magnetization of ferrite magnetic powder is 35~65 emu / g, that of iron-based nanocrystals and permalloy is 40~85 emu / g, and that of modified graphite and graphene composite magnetic powder is 5~45 emu / g. High-saturation pure iron and cobalt elemental powders, due to their specific saturation magnetization exceeding 100 emu / g, need to be modified by oxidation and alloy doping to reduce the magnetic moment to below 90 emu / g before they can be used. In this application, the term "single magnetic sensor" refers to a sensor in a smoke-generating body that contains only one material (magnetic element or alloy), has a single-layer physical structure and a single Curie temperature, which differs from the "composite sensor" in the prior art, which is composed of composite metal materials and has a multi-layer physical structure and multiple Curie temperatures. In contrast, the manufacturing process of a single magnetic sensor is simpler, offers greater flexibility in thickness design, and has lower material and processing costs; however, its magnetic characteristics, such as magnetic induction intensity, are weakened to some extent. In this embodiment, the composite configuration of "internal single magnetic sensor 200 and external magnetic particles 400" based on the smoke generator 100 not only compensates for this weakening effect but also endows the aerosol product with more signal feedback capabilities.

[0033] This application configures magnetic particles 400 with high permeability and resistivity as a discretely distributed fine powder. On the one hand, the superposition of internal and external magnetism can significantly enhance the overall magnetic baseline level of the aerosol product, increasing the probability of a single magnetic sensor 200 being recognized by the induction coil and improving the coupling strength. On the other hand, while maintaining its extremely weak heating effect, it remains in a high magnetic state and maintains magnetic stability, which can significantly reduce the ratio of the overall magnetic variation amplitude, i.e., the ratio of the change in magnetism of a single magnetic sensor 200 with temperature change to the baseline level, thereby maintaining coupling stability. It is worth noting that one of the core technical approaches of this application is to construct a synergistic magnetic distribution and feedback structure based on differences in position, size, and magnetic characteristics, and accordingly utilize temperature differences, heating rate differences, and magnetic stability to achieve multiple functions.

[0034] From the perspective of positional differences, considering that when aerosol products are used with common solenoid induction coils, the magnetic field is stronger and the temperature changes more significantly in the region inside the smoke-generating body 100 near the central axis, reaching a high temperature of 350°C or even higher under stable operating conditions, a single magnetic sensor 200 is centrally located here. Outside the smoke-generating body 100, the magnetic field is weaker and the temperature changes less, reaching a lower temperature of as low as 50°C under stable operating conditions, where magnetic particles 400 are discretely arranged. This configuration allows the aerosol product to be efficiently identified by its high overall magnetism within the induction coil, while simultaneously focusing eddy current heating onto a single magnetic sensor 200, which then acts on the smoke-generating matrix, ensuring that the magnetic particles 400 are in a state of weak self-heating and exhibit weak magnetic fluctuations under small temperature changes.

[0035] In this embodiment, the induction coil generates an alternating magnetic field under the high-frequency resonance of the electronic circuit system. Typically, the magnetic field is strongest in the region where the central axis of the inner side of the solenoid induction coil is located. As the distance increases from the center point of the induction coil along the axial and radial directions, the magnetic field strength gradually decreases.

[0036] In this embodiment, the magnetic field generated by the induction coil was simulated and analyzed using COMSOL Multiphysics software, with reference to... Figure 18As shown, in this model, the induction coil is a circular solenoid without a magnetic flux concentrator on its periphery. Its inner diameter is R0 (9mm, defined as the effective width), and its height is L0 (14mm, defined as the effective height). The height L0 is the vertical distance between the upper and lower ends of the induction coil winding along the central axis. The magnetic field strength on the central axis exhibits a smooth, single peak characteristic within the effective height L0 and effective width R0 segments, reaching its maximum value at the center of both segments. The center of the effective height and effective width segments is the central region of the induction coil, where the overall magnetic field strength is highest. As the distance from the central region increases, the magnetic field strength gradually decreases. In addition to the high-density magnetic field lines inside the induction coil, there are still magnetic field lines of a certain intensity distributed at both ends of the axial direction (e.g., the two L1 regions in the axial direction) and on both outer radial directions (e.g., the two R1 regions in the radial direction). The magnetic field distribution in these regions can be used to enhance the detection, identification, and signal feedback of aerosol products.

[0037] In this application, a single magnetic sensor 200 in the aerosol product is placed in the central region of the effective width segment, and correspondingly, magnetic particles 400 are placed in the edge region (outer peripheral region) of the effective width segment, adjacent to the outer surface of the smoke generator 100 in the radial direction. The magnetic particles 400 themselves are strongly magnetic; although falling into a relatively weak magnetic field region, they can still be effectively magnetized, thus becoming an additional magnetic source, thereby enhancing the overall magnetism of the aerosol product. Even if the internal single magnetic sensor 200 exhibits material deviations, dimensional errors, assembly errors, or fails to reach a preset position (e.g., angular mismatch), the magnetic characteristics of the aerosol product can still meet the preset threshold conditions in the aerosol generating device, thus passing identification and authentication and functioning normally. Therefore, this configuration of the magnetic particles 400 can significantly reduce the requirements for material uniformity, processing accuracy, assembly accuracy, and positional accuracy of the single magnetic sensor 200, thereby improving manufacturability and enhancing the user experience.

[0038] It should be understood that, in this embodiment, the magnetic particles 400 not only increase the probability of aerosol products passing the identification operation, but also achieve strong coupling, enabling the induction coil to continuously and stably input energy with a large power. This effectively shortens the time for a single magnetic sensor 200 to reach the expected operating temperature, increases its heating speed on the smoking matrix, and rapidly releases aerosols, further enhancing the user experience.

[0039] From the perspective of morphological and dimensional differences, the single magnetic sensor 200 is a concentrated, elongated, sheet-like continuous phase, while the magnetic particles 400 are multiple discretely distributed, tiny powdery phases. Even using the same materials under the same magnetic field strength, they will produce significantly different eddy current heating effects. Furthermore, the single magnetic sensor 200 is located in a strong magnetic field region, achieving a higher magnetic induction intensity and higher heating efficiency, while the magnetic particles 400 are located in a weaker magnetic field region, achieving a lower magnetic induction intensity and lower heating efficiency. This configuration satisfies the different thermal energy requirements at different locations in this invention, namely, internal heating and external cooling.

[0040] The underlying logic mainly stems from the method for calculating the heating power P of a magnetic conductor located in an alternating magnetic field, which is expressed by the following formula (1): (1) Where B is the magnetic flux density, measured in Tesla (T); f is the frequency of the alternating magnetic field, measured in Hertz (Hz); d is the thickness of the conductor, measured in meters (m); and V is the volume of the conductor, measured in cubic meters (m³). 3 ); ρ is the resistivity of the conductor, with units of ohm-meter (Ω·m).

[0041] Formula (1) above shows that, under the premise that other parameters are fixed, the heating power P is proportional to the magnetic induction intensity, the square of the thickness of the magnetic conductor, and the volume of the magnetic conductor, respectively. Based on this, the B, d, and V of the single magnetic sensor 200 located in the central region are much larger than those of the magnetic particles 400 located in the edge region; therefore, the heating power P of the single magnetic sensor 200 is much larger. c It is also much greater than the heating power P of the magnetic particles 400. e .

[0042] Specifically, in this embodiment, the magnetic particles 400 are fine powders distributed discretely. The magnetic field loops through which the magnetic field lines pass are extremely short, resulting in a very weak eddy current effect, thus the particles themselves do not heat up significantly. Nevertheless, the magnetic particles 400 can significantly enhance the overall magnetism of the aerosol product without generating a significant eddy current heating effect themselves. This allows the aerosol product to accept a strong power input, and most of this input power is converted into a single magnetic sensor 200, thereby further improving its heating rate.

[0043] It should be understood that, in this embodiment, the magnetic particles 400 not only increase the probability of aerosol articles being identified and accelerate the heating rate of a single magnetic sensor 200, but also enable more stable temperature control of the entire aerosol generation system (including the aerosol articles and the aerosol generation device). This is due to the contributions of the following four aspects.

[0044] Firstly, the magnetic particles 400 and the single magnetic sensor 200 compete with each other in the alternating magnetic field. The magnetic particles 400 can disperse the input power of the system, making the power ratio adjustment process on the single magnetic sensor 200 smoother, thereby reducing local overheating caused by temperature overshoot and preventing the generation of harmful substances and local overcarbonization during the heating of the smoke generator 100 due to excessive temperature.

[0045] Secondly, given its limited heat generation, the magnetic particles 400 can construct more internal magnetic circuits, reducing magnetic circuit losses in the air gap, thereby reducing system energy loss and making system temperature control more effective.

[0046] Thirdly, the magnetic particles 400 can conduct some magnetic lines of force, generating a certain magnetic field shielding effect and reducing interference to nearby circuit board modules and other components. At the same time, since their own heat generation is limited, they will not have a significant thermal impact on the carrier 300 and surrounding components, and can also avoid the generation of odors due to high-temperature heating of the carrier 300. As a result, the magnetic field coupling, heating effect, and working status of nearby components of the entire system are more stable, which further facilitates more stable temperature control of the single magnetic sensor 200.

[0047] Fourthly, the magnetic particles 400 can significantly improve the overall magnetic reference level of the aerosol product. Because their own magnetic strength changes very little with temperature, their magnetic coupling with the induction coil remains stable. This reduces the relative amplitude of the change in permeability of a single magnetic sensor 200 with temperature (i.e., the ratio of its absolute change in permeability to the overall magnetism of the aerosol product), resulting in a smoother change in the sensor's permeability. Combined with these effects, the entire aerosol exhibits a more balanced magnetic response with temperature changes, improving the stability of feedback signals such as inductance, which in turn facilitates more precise and stable temperature control of the magnetic excitation system.

[0048] In this embodiment, any carrier 300 that satisfies the requirement of carrying magnetic particles 400 is suitable for the carrier 300 of this application embodiment. For example, the carrier 300 can be configured as a smoke-generating medium 700 or as an adhesion medium 800. When the carrier 300 is configured as a smoke-generating medium 700, refer to... Figures 6 to 11 The magnetic particles 400 can be placed on the smoke-generating medium 700, which serves as the carrier 300, either by pre-addition or post-addition.

[0049] For the pre-addition method, it refers to mixing magnetic particles 400 during the preparation of the smoke-generating medium 700, as per reference. Figure 6 , Figure 7 and Figure 8 At this point, the smoke-generating medium 700 is a smoke-generating medium containing magnetic particles 400.

[0050] For the post-addition method, it refers to placing the magnetic particles 400 onto the smoke-generating medium 700, which serves as the carrier 300, after the carrier 300 has been formed, using a predetermined forming method. This predetermined forming method includes, but is not limited to, one of the following: spraying, coating, or printing. (See reference...) Figure 9 , Figure 10 and Figure 11 At this time, the smoke-generating medium 700 is a smoke-generating medium 700 with magnetic particles 400 covering its surface.

[0051] The smoke-generating medium 700 can be the smoke-generating matrix 500 itself, see reference. Figure 6 and Figure 9 At this point, the smoke-generating matrix 500 has a dual function: it possesses smoke-generating properties and also serves as a carrier for the magnetic particles 400. In some embodiments, the smoke-generating medium 700 is the smoke-generating matrix 500, and the carrier 300 and the smoke-generating matrix can be configured as a smoke-generating sheet 600. It should be understood that a smoke-generating sheet refers to a smoke-generating sheet with a long and flat shape, such as tobacco sheets or non-tobacco sheets.

[0052] Smoke sheet 600 can be Figure 4 , Figure 5 , Figure 8 , Figure 11 and Figure 13 The smoke-generating sheet 600 shown, the smoke-generating medium 700 acting as the carrier 300, and the magnetic particles 400 are arranged in a pre-addition method (see reference). Figure 8 ) and the method of adding later (see reference) Figure 11 It should be noted that... Figure 5 The carrier 300 and magnetic particles 400 can be added pre- or post-addition.

[0053] The smoke-generating medium 700 can also be a non-smoke-generating matrix, see reference. Figure 7 and Figure 10 At this time, the non-smoke-generating matrix, as the smoke-generating medium 700, only serves as the attachment carrier for the magnetic particles 400 and does not have smoke-generating properties. It combines the magnetic particles 400 with the smoke-generating matrix 500, which has smoke-generating properties and performs the smoke-generating function, to form a smoke-generating body 100.

[0054] The following descriptions of the smoke-generating body 100 in the paste structure are provided, using the smoke-generating medium 700 as the smoke-generating matrix 500 and the non-smoke-generating matrix respectively: When the smoke-generating body 100 has a paste structure and the smoke-generating medium 700 is the smoke-generating matrix 500, magnetic particles 400 are added to the smoke-generating matrix 500 before expansion molding. After expansion molding, the magnetic particles 400 are mixed in the smoke-generating matrix 500 near the radially outer side. Figure 6 .

[0055] When the smoke-generating body 100 has a paste structure and the smoke-generating medium 700 is the smoke-generating matrix 500, after expansion molding, magnetic particles 500 are placed on the radially outer surface of the smoke-generating matrix 500 by spraying or coating. (Refer to...) Figure 9 .

[0056] When the smoke-generating body 100 has a paste structure and the smoke-generating medium 700 is a non-smoke-generating matrix, refer to Figure 7 When the carrier 300 is formed with a non-smoke-generating matrix, magnetic particles 400 are mixed into the non-smoke-generating matrix to form a smoke-generating medium layer containing magnetic particles 400. The smoke-generating medium layer is then combined with a smoke-generating matrix that has smoke-generating properties to obtain the corresponding smoke-generating body 100.

[0057] When the smoke-generating body 100 has a paste structure and the smoke-generating medium 700 is a non-smoke-generating matrix, refer to Figure 10 After forming a carrier 300 with a non-smoke-generating matrix, magnetic particles 500 are placed on the radially outer surface of the smoke-generating medium 700 by spraying or coating, thereby forming a smoke-generating medium layer containing magnetic particles 400. This smoke-generating medium layer is then combined with a smoke-generating matrix possessing smoke-generating properties to obtain the corresponding smoke-generating body 100. (Refer to...) Figure 10 .

[0058] The following descriptions of the sheet-structured smoke generator 100, using the smoke-generating medium 700 as both the smoke-generating matrix 500 and the non-smoke-generating matrix, illustrate this further: When the smoke-generating body 100 has a thin sheet structure and the smoke-generating medium 700 is the smoke-generating matrix 500, reference Figure 5 and Figure 8 Magnetic particles 400 can be added during the preparation of non-tobacco smoke-generating sheets (expanded smoke-generating sheets) to form non-tobacco sheet units (corresponding to...) Figure 5 The outermost position of the 600 in the middle has magnetic particles 400.

[0059] When the smoke-generating body 100 has a thin sheet structure and the smoke-generating medium 700 is a non-smoke-generating matrix, refer to... Figure 5 and Figure 11 A non-smoking matrix is ​​first formed on the surface of at least the outer layer of the smoking sheet (which may be a tobacco sheet). Then, magnetic particles 500 are placed on the radial outer surface of the smoking medium 700 by spraying or coating, thereby forming a smoking medium layer containing magnetic particles 400. The smoking medium layer is then combined with a smoking matrix that has smoking properties to obtain the corresponding smoking body 100.

[0060] The carrier 300 can be configured as an adhesion medium 800, which means that the magnetic particles 400 are mixed with the carrier 300 as a substrate so that the mixture of magnetic particles 400 and carrier 300 can be applied to the outer peripheral surface of the smoke matrix 500.

[0061] It is understandable that if only the magnetic particles 400 and the smoke matrix 500 are covered, it is difficult to disperse the magnetic particles 500. By using an adhesive medium, the magnetic particles 400 can be quickly covered on the outer surface of the smoke matrix 500.

[0062] The adhesive medium 800 may have adhesive properties. For example, the adhesive medium 800 may be configured as an adhesive. In this case, after mixing the adhesive with the magnetic particles 400, the adhesive is applied to the outer surface of the smoke-generating matrix 500 in a preset covering manner, so that the magnetic particles 400 are dispersed in a preset area.

[0063] For the covering method, it can be spraying, coating, printing, etc., see reference. Figures 12 to 14 In some alternative embodiments, the mixture of magnetic particles 400 and adhesive is sprayed onto the outer peripheral surface of the smoke-generating matrix 500 using a spray gun. In some alternative embodiments, a coating machine is used to coat the mixture of magnetic particles 400 and adhesive onto the outer peripheral surface of the smoke-generating matrix 500. In some alternative embodiments, inkjet printing can also be used to coat the mixture of magnetic particles 400 and adhesive onto the outer peripheral surface of the smoke-generating matrix 500.

[0064] For the smoke-generating matrix 500 and the corresponding smoke-generating body 100 that meet the requirements of the covering method processing, it can be Figure 12 and Figure 13 The thin-sheet smoke generator 100 shown can also be Figure 14 The fuming body 100 with the paste structure shown.

[0065] In this embodiment, the smoke-generating body 100 is an assembly of smoke-generating matrices 500. The smoke-generating matrices 500 can be configured as integrally formed rod-shaped smoke-generating matrices as needed (see reference). Figure 3 , Figure 12 ), clustered smoke-emitting flakes (reference) Figure 4 , Figure 5 and Figure 13 ), clustered smoke lines (reference) Figure 14 One of them is smoke-generating particles, etc. The integrally molded rod-shaped smoke-generating matrix is ​​divided into smoke-generating matrix formed by extrusion of ultrafine powder and smoke-generating matrix formed by paste.

[0066] To achieve the coating of the smoke-generating body 100, in this embodiment, reference is made to... Figures 2 to 5 ,as well as Figures 12 to 14 The smoke-generating body 100 is surrounded by packaging paper 900, and the carrier 300 is placed between the smoke-generating body 100 and the packaging paper 900.

[0067] Different packaging papers 900 can be configured according to different packaging requirements, such as outer packaging paper 130 and inner packaging paper 140. The outer packaging paper 130 refers to the paper material that can wrap multiple components such as the smoke generator 100 at the same time without directly contacting the smoke generator 100, while the inner packaging paper 140 refers to the paper material that directly contacts the smoke generator 100 and limits the smoke generator 100.

[0068] When the smoke-generating body 100 is surrounded by an outer packaging paper 130 and an inner packaging paper 140, and the inner packaging paper 140 covers the smoke-generating body 100, refer to Figure 15 At this time, the smoke-generating body 100 is constrained by the inner packaging paper 140, the carrier 300 is placed between the smoke-generating body 100 and the inner packaging paper 140, and the outer packaging paper 130 simultaneously wraps the smoke-generating body 100 and other components.

[0069] When the smoke-generating body 100 is surrounded by an outer packaging paper 130 and an inner packaging paper 140, and the inner packaging paper 140 also wraps multiple components such as the smoke-generating body 100, see reference. Figure 16 At this time, the smoke-generating body 100 is constrained by the inner packaging paper 140, the carrier 300 is placed between the smoke-generating body 100 and the inner packaging paper 140, and then the outer packaging paper 130 is pasted on the outside of the inner packaging paper 140. The outer surface of the outer packaging paper 130 can be printed with a label.

[0070] In another embodiment, only one layer of packaging paper 900 is provided around the outer periphery of the smoke-generating body 100, as shown in the reference. Figure 17 At this time, after the smoke-generating body 100 is wrapped by the packaging paper 900, other components such as the cooling section 110, the filter section 120, and the plug 150 are also wrapped simultaneously, thereby preparing aerosol products. In other words, the function of constraining the smoke-generating matrix 500 and wrapping other components is achieved through a layer of paper.

[0071] refer to Figure 1 , Figure 2 and Figure 15 In Example 1 of this aerosol product, a smoke-generating matrix 500 is injected into a tube 600 partially formed with packaging paper 900 to form a smoke-generating body 100, and then other components (e.g., ...) are placed into the tube. Figure 1 The aerosol product consists of a cooling section 110, a filtering section 120, and a plug 150. The outermost layer is the tube body, and then outer packaging paper 130 is attached to the outer surface of the tube body. Labels can be printed on the outside of the outer packaging paper 130, or label paper can be used directly as the outer packaging paper 130. The tube body serves as the inner packaging paper 140, which is rolled together. The label paper is self-labeling paper.

[0072] refer to Figure 16In Example 2 of this aerosol product, the smoke-generating matrix and other components are first wrapped with inner packaging paper 140 to form the entire aerosol product. Then, outer packaging paper 130 is attached to the outside of the inner packaging paper 140. At the same time, a label can be printed on the outer surface of the outer packaging paper 130.

[0073] In some embodiments, the inner packaging paper 140 may be a hollow tube corresponding to the molded smoke generator 100. The hollow tube may be a thin paper tube, a rigid paper tube, an aluminum foil paper tube, a tin foil paper tube, a high-temperature resistant plastic tube, or a high-temperature resistant silicone tube, which is formed by rolling paper into a hollow tube.

[0074] In this embodiment, to prevent the absorbent material inside the smoke-generating body 100 from absorbing moisture from the air through the outer carrier and becoming damp, the aerosol product of this application embodiment is further provided with an outer packaging paper consisting of an impermeable base paper and an ink layer on the outside of the formed smoke-generating body 100. This outer packaging paper can be the outer packaging paper 130 described in the above embodiments, or it can be a separate impermeable paper provided outside the outer packaging paper 130. The materials used are odorless, tasteless, and non-toxic. The adhesive used to adhere to the smoke-generating body 100 is a food-grade quick-drying adhesive or a self-adhesive adhesive, which is harmless to the human body during the suction process. The weight per square meter of the impermeable base paper is 10~100 g / m². 2 Preferably 25~45 g / m 2 The ink used is food-grade ink. Because the impermeable base paper is difficult to absorb moisture, it can prevent the water-absorbing material in the smoke-generating body 100 from absorbing moisture from the air through the carrier and outer packaging layer, thus avoiding moisture. This keeps the aerosol product of this application embodiment aesthetically pleasing and prevents bacteria or mold growth on the surface of the cigarette due to liquid penetration.

[0075] In this embodiment, the smoke-generating matrix 500 can be expanded by microwave or high-frequency heating. Utilizing the strong penetrating power of microwaves or high-frequency alternating fields, the smoke-generating matrix can be heated simultaneously inside and out without heat conduction, thus achieving uniform heating and expansion in a short time.

[0076] In some alternative embodiments, the hollow tube containing the fuming matrix is ​​placed in a microwave oven or high-frequency oven. After being subjected to microwave or high-frequency radiation, the material expands, forming micropores inside. Because the fuming matrix expands both internally and externally, the outer portion of the fuming matrix adheres to the inner wall of the hollow tube, forming an integral structure with the tube. In other embodiments, the microwave or high-frequency heating process can be performed under vacuum. This allows for good aging of the fuming matrix under uniform temperature control, eliminating odors and resulting in a milder flavor. Using fuming matrix also offers advantages in molding processes: it allows for more precise control of the position of receptors located inside the fuming body, effectively reducing receptor position shifts caused by subsequent transportation and other processes.

[0077] In this embodiment, for the size of the magnetic particle 400, the design of this application aims for magnetic particles with an equivalent diameter at the micro-nano scale and a relatively consistent size distribution. In one embodiment, the average particle size of the magnetic particles 400 is 1~50000 nm (nanometers); optionally, the average particle size of the magnetic particles 400 can be any one or any two of the following: 1 nm, 5 nm, 10 nm, 100 nm, 1000 nm, 10000 nm, 15000 nm, 20000 nm, 25000 nm, 50000 nm, etc., without limitation. In this embodiment, the micro-nano scale size can meet the aforementioned requirements of low heat generation, low energy consumption, low temperature, effective shielding, and high magnetism; at the same time, the size should not be too small or too large. If the average particle size of the magnetic particles 400 is too small, for example, less than 1 nm, it is easy to increase its production and processing costs; if the average particle size of the magnetic particles 400 is too large, for example, greater than 50000 nm, it is easy to cause precipitation and segregation during mixing or coating with other raw materials, which is not conducive to uniform dispersion. From the perspective of differences in magnetic characteristics, several key parameters include permeability, resistivity, and temperature coefficient of resistance.

[0078] Regarding permeability and resistivity, based on the aforementioned formula (1), high permeability and low resistivity are beneficial for eddy current heating. However, high permeability also leads to large magnetic fluctuations when the temperature changes, affecting the stability of heating. Therefore, in this application, the single magnetic sensor 200 is set to a metallic material with medium or low magnetism and high resistivity, while the magnetic particle 400 is set to a material with high magnetism and high resistivity, including at least one of metallic materials, metal oxides, and carbon-based materials. In this configuration, the single magnetic sensor 200 is excited by a high-intensity magnetic field in the central region to generate efficient heating, while the magnetic particle 400 is detected and identified by a low-intensity magnetic field in the edge region, limiting its own heating effect, so as to achieve the purpose of rapid heating, stable temperature control, and multifunctional signal feedback.

[0079] In some embodiments, the material of the single magnetic sensor 200 includes at least one of elemental iron, elemental nickel, elemental cobalt, iron alloys, nickel alloys, cobalt alloys, Tenets alloys, Permalloy, iron-aluminum alloys, iron-silicon-aluminum alloys, iron-chromium-aluminum alloys, iron-cobalt alloys, nickel-chromium alloys, Sendastel alloys, iron-based / nickel-based / cobalt-based amorphous alloys, neodymium-iron-boron alloys, samarium-cobalt alloys, aluminum-nickel-cobalt alloys, iron-chromium-cobalt alloys, silicon steel, and magnetic stainless steel. These materials are configured to have moderate or low magnetism while having high resistivity, meeting the heating characteristics requirements inside the smoke generator 100.

[0080] In one embodiment, the Curie temperature of the single magnetic sensor 200 is 300~800°C. Optionally, the Curie temperature of the single magnetic sensor 200 can be any one or any two of 300°C, 350°C, 400°C, 450°C, 500°C, 600°C, 700°C, 770°C, 800°C, etc., and is not limited here.

[0081] In some embodiments, the magnetic particles 400 are made of at least one of the following: elemental iron, elemental nickel, elemental cobalt, iron alloys, nickel alloys, cobalt alloys, iron oxides, cobalt oxides, nickel oxides, ferrites, iron-based / cobalt-based / nickel-based nanocrystalline soft magnetic alloys, permalloys, composite magnetic alloy materials, modified graphite, and modified graphene.

[0082] In one embodiment, the Curie temperature of the magnetic particle 400 is 200~1100°C. Optionally, the Curie temperature of the magnetic particle 400 can be any one or any two of 200°C, 400°C, 500°C, 600°C, 700°C, 800°C, 900°C, 1000°C, 1100°C, etc., and is not limited herein.

[0083] For a resistance temperature system, a positive temperature resistivity is advantageous for the magnetic particles 400 in this application. In a positive temperature coefficient material, as the temperature rises, the lattice vibrations inside the material intensify, enhancing the scattering effect on charge carriers (such as electrons), leading to a decrease in charge carrier mobility, which in turn increases the resistivity, further limiting the self-heating of the magnetic particles 400.

[0084] In some embodiments, the magnetic particle 400 has a positive temperature resistivity. Its resistivity is related to temperature by the following formula (2): (2) in, is the resistivity of magnetic particle 400 at temperature T, in ohm-meter (Ω·m). α is the resistivity of magnetic particle 400 at reference temperature T0, i.e., the resistivity value at the base temperature, in Ω·m; α is the temperature coefficient of resistivity, representing the relative change in resistivity caused by a unit change in temperature, in degrees Celsius (°C). -1 T represents the current temperature in degrees Celsius (°C); T0 represents the reference temperature (baseline temperature), usually a value such as 0°C or room temperature (20°C), in degrees Celsius (°C).

[0085] According to formula (2), when the magnetic particle 400 itself generates heat and begins to overheat due to the influence of the temperature of adjacent components, the resistivity ρ increases under the influence of the positive temperature resistivity. Combined with formula (1), its heating power P can be deduced. e The temperature will drop, thereby achieving self-limiting temperature protection for the magnetic particles 400 to prevent the external temperature of the smoke generator 100 from becoming too high.

[0086] The amount of magnetic particles 400 also affects the overall magnetic characteristics of the aerosol product. In this application, an appropriate amount of magnetic particles is set based on the magnetic characteristics of a single magnetic sensor 200 and the control program of the aerosol generation system.

[0087] In one embodiment, the coating thickness of the magnetic particles 400 is 20~200μm (micrometers). Optionally, the coating thickness of the magnetic particles 400 can be any one or any two of the following: 20μm, 30μm, 40μm, 50μm, 60μm, 80μm, 90μm, 100μm, 120μm, 150μm, 180μm, 200μm, etc., and is not limited herein.

[0088] In one embodiment, the mass ratio of magnetic particle 400 to single magnetic sensor 200 is (0.3~3):1.

[0089] In this embodiment, the mass ratio of the magnetic particle 400 to the single magnetic sensor 200 can be any one of the following values: 0.3:1, 0.5:1, 0.8:1, 1:1, 1.5:1, 1.8:1, 2:1, 3:1, or any range between the two. The specific value is not limited here. If the mass ratio of magnetic particles 400 to the single magnetic sensor 200 is too large, the following problems will arise: First, it will easily increase the material cost of magnetic particles 400; second, the overall magnetism of magnetic particles 400 may be much higher than that of the single magnetic sensor 200, causing it to "overshadow" the single magnetic sensor 200, thus significantly weakening the coupling effect between the single magnetic sensor 200 and the magnetic excitation system, affecting its dominant position in coupling with the magnetic excitation coil, and hindering the single magnetic sensor 200 from generating the preset magnetic strength and eddy current effect in the magnetic field, thereby reducing the probability of the aerosol product passing the recognition operation; in addition, an excessively large mass ratio may also easily lead to uneven mixing and dispersion of magnetic particles 400 in the raw materials during the preparation of packaging paper 900, resulting in excessively high hardness of the finished packaging paper 900, which is not conducive to product demolding, cutting, and assembly. Conversely, if the mass ratio of magnetic particles 400 to the single magnetic sensor 200 is too small, the effect of magnetic particles 400 in enhancing the overall magnetism of the aerosol product will be unsatisfactory, reducing its role in concentrating magnetic flux and conducting electromagnetic waves.

[0090] In one embodiment, the magnetic particles 400 have a mass of 6 to 150 mg.

[0091] In this embodiment, the selectable mass of the magnetic particles 400 is any one of 6mg, 10mg, 20mg, 40mg, 60mg, 80mg, 100mg, 120mg, and 150mg, or any range between two values, and the specific value is not limited here. If the mass of the magnetic particles 400 is too large, the following problems will arise: First, it will easily increase the material cost; second, it may cause the overall magnetism of the magnetic particles 400 to be higher than that of the single magnetic sensor 200, thereby significantly weakening the coupling between the latter and the magnetic excitation system, affecting the dominant position of the coupling between the single magnetic sensor 200 and the magnetic excitation coil, which is not conducive to generating the preset magnetic strength and eddy current effect in the magnetic field; in addition, excessive mass may also easily lead to uneven mixing and dispersion of the magnetic particles 400 in the raw materials during the preparation of the packaging paper 900, resulting in excessively high hardness of the prepared packaging paper 900, which is not conducive to its demolding, cutting, and assembly. Conversely, if the mass of the magnetic particles 400 is too small, it will result in an unsatisfactory effect on enhancing the overall magnetism of the aerosol product, reducing its role in concentrating magnetic flux and conducting electromagnetic waves.

[0092] In some embodiments, the aerosol article further includes a plug 150, a cooling section 110, and a filter section 120, wherein the plug 150, the smoke generator 100, the cooling section 110, and the filter section 120 are arranged sequentially along the axial direction of the aerosol article.

[0093] Understandably, reference Figure 1 By setting the plug 150, the length of the magnetic field region is strengthened in the effective height direction. The plug 500 and the smoke generator 100 are arranged adjacent to each other in the axial direction of the smoke generator 100. The plug 500 can be located near the center region of the induction coil, so that the plug 500 can fall into the space with strong magnetic field strength. The magnetic particles 400 dispersed on the plug 500 can be effectively magnetized in the alternating magnetic field, thus becoming an additional magnetic source. The magnetic particles 400 participate in the coupling between the aerosol product and the induction coil, which further enhances the overall magnetism of the aerosol product and has multi-faceted signal feedback function characteristics.

[0094] This application also provides an aerosol generating device, including an induction coil, an electronic circuit system, and the aerosol product described in the above embodiments; the induction coil is capable of generating an alternating magnetic field, and a single magnetic sensor 200 and magnetic particles 400 are located in the alternating magnetic field.

[0095] During the operation of the aerosol generation system, the aerosol generator typically performs an identification operation on the aerosol product. This identification operation is based on the magnetic characteristics of the aerosol product, contributed by a single magnetic sensor 200 and magnetic particles 400. It captures changes in one or more physical quantities in the electronic circuitry caused by the aerosol product entering or leaving an alternating magnetic field, or by changes in temperature or position within the alternating magnetic field. Then, based on preset threshold conditions, appropriate response actions are taken, such as: activating power input, increasing power input, decreasing or cutting off power input, adjusting the amplitude or duty cycle of the power input, and controlling the remaining heating time.

[0096] This application also provides an aerosol generation system, including an aerosol product and a magnetic induction heating smoke device for heating the aerosol product, wherein the aerosol product includes the aerosol product in the above embodiments.

[0097] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
