Description

Technical Field

[0001] This invention relates to the field of aerosol generation technology, and more particularly to aerosol products and aerosol generating devices. 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] 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

[0014] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] The technical problem that this application aims to solve is described below:

[0033] 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.

[0034] 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.

[0035] 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.

[0036] To solve the above problems, refer to Figures 1 to 9 This application provides an aerosol product, including a smoke-generating body 100, a single magnetic sensor 200, packaging paper 300, and magnetic particles 400. The single magnetic sensor 200 is embedded in the smoke-generating body 100 and can generate heat energy in an alternating magnetic field to heat the smoke-generating body 100. The packaging paper 300 is arranged radially outside the smoke-generating body 100, and the magnetic particles 400 are dispersed at target positions on the packaging paper 300. 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. The packaging paper 300 is also used to constrain the magnetic particles 400 radially outside the smoke-generating body 100.

[0037] 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 comparison, the manufacturing process of a single magnetic sensor is simpler, the thickness design is more flexible, and the material and processing costs are lower; 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-generating body 100 not only compensates for this weakening effect but also endows the aerosol product with more signal feedback functions.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] In this embodiment, the magnetic field generated by the induction coil was simulated and analyzed using COMSOL Multiphysics software, with reference to... Figure 9 As 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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).

[0046] 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 .

[0047] 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 increasing its heating rate.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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 packaging paper 300 and surrounding components, and can also avoid the generation of odors caused by high-temperature heating of the packaging paper. 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.

[0052] 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.

[0053] Regarding size, this application aims for magnetic particles with equivalent diameters at the micro-nano scale and relatively uniform 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.

[0054] refer to Figures 1 to 8 To achieve the setting of corresponding magnetic particles 400 on the outer side of the aerosol product in the radial direction, and to set packaging paper 300 as a carrier substrate, while also constraining and shaping the smoke-generating body 100, the smoke-generating matrix inside the smoke-generating body 100 can be formed by various methods, such as expansion.

[0055] In some embodiments, the packaging paper 300 includes a first packaging paper for constraining and shaping the smoke-generating body 100, the smoke-generating body 100 containing an expanded smoke-generating matrix, and the inner sidewall of the first packaging paper is in contact with the smoke-generating matrix.

[0056] In this embodiment, the first packaging paper can be a hollow tube corresponding to the molded smoke body 100. The hollow tube can be 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, providing the hardness and heat resistance characteristics required by the embodiment of the present invention.

[0057] In this embodiment, the smoke-generating matrix extruded into the hollow tube is expanded using 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 from the inside out, eliminating the need for heat conduction and thus achieving uniform heating and expansion in a short time.

[0058] In some alternative embodiments, a microwave heating device (such as a microwave oven) is used, with a heating power of 1~100KW, a heating temperature of 30~80°C, and a heating time of 30~180 minutes. Preferably, the heating power is 10~20KW, the heating temperature is 45~60°C, and the heating time is 30~80 minutes. In other embodiments, a high-frequency heating device (such as a high-frequency baking oven) is used, with an operating frequency of 1~30MHz (megahertz), a heating temperature of 30~80°C, and a heating time of 30~180 minutes. Preferably, the high-frequency heating device provides a heating frequency of 5~15MHz, a heating temperature of 45~60°C, and a heating time of 30~80 minutes. It can be understood that when a hollow tube containing a smoking matrix is ​​placed in a microwave oven or a high-frequency baking oven, the material expands after being acted upon by microwaves or high frequency, forming tiny pores inside. Because the sludge in the smoking matrix expands simultaneously inside and out, the outer portion of the sludge material adheres to the inner wall of the hollow tube, forming an integral structure with the tube. In other embodiments, the aforementioned microwave or high-frequency heating process can be carried out under vacuum. This allows the sludge in the smoking matrix to achieve a good aging effect under uniform temperature control, eliminating off-odors and making its taste more mellow. Using sludge as the smoking matrix also has advantages in molding process: it can more precisely limit the position of the receptors located inside the smoking body, effectively reducing receptor position displacement caused by subsequent transportation and other processes.

[0059] To achieve effective dispersion of the magnetic particles 400, in some embodiments, the magnetic particles 400 are dispersed in the first packaging paper using one of the following methods:

[0060] Method 1: Add magnetic particles 400 to the pulp to prepare the first packaging paper containing magnetic particles 400.

[0061] Specifically, this method involves adding magnetic powder during the papermaking process, distributing magnetic particles 400 throughout the first packaging paper. After the first packaging paper is formed into a hollow tube and a smoke-generating semi-finished product is produced, the magnetic particles 400 are dispersed radially on the outer side of the smoke-generating body 100. It should be noted that the amount of magnetic powder added should meet the smoke generation requirements; simultaneously, during the papermaking process, the magnetic particles 400 can be dispersed at a predetermined location (e.g., the outer layer of the paper) to ultimately position them at the target location on the packaging paper 300.

[0062] Method 2: Add magnetic particles 400 between the two layers of composite paper of the first packaging paper.

[0063] In this method, the first packaging paper is composed of two or more layers of paper. To distribute the corresponding magnetic particles 400 on the packaging paper, they can be filled between the two layers of composite paper. This satisfies the requirements for composite paper forming while also distributing the magnetic particles 400 on the packaging paper 300 to improve cigarette identification accuracy. Furthermore, a grid-shaped medium, such as a honeycomb pattern, can be added between the two layers of composite paper to divide and store the magnetic particles 400. By adjusting the positions of the compartments storing the magnetic particles 400, different distribution patterns of the magnetic particles 400 can be achieved.

[0064] Method 3: Magnetic particles 400 are pre-coated on the radial inner and / or radial outer sides of the tubular first packaging paper.

[0065] In this method, the papermaking process is completed first, and then magnetic particles 400 are pre-coated on the top and / or bottom layers of the resulting packaging paper 300. Next, the packaging paper is formed into a tube, and a smoke-generating matrix is ​​extruded into the corresponding tube. After expansion treatment, a smoke-generating body semi-finished product is formed, so that the magnetic particles 400 are located on the radial outer periphery of the smoke-generating body 100.

[0066] Method 4: Magnetic particles 400 are coated on the radial outer surface of the first packaging paper after the smoke body 100 is constrained and shaped.

[0067] In this method, a semi-finished product of smoke body 100 is first formed and prepared. Then, magnetic particles 400 are coated on the outer layer of the semi-finished product according to preset requirements (such as shape and distribution position), so that the formed smoke body 100 has magnetic particles 400 dispersed on the radial outer periphery.

[0068] Method 5: On the first packaging paper of the formed smoke-generating body 100, magnetic particles 400 are filled in the radially concave anticlinal space.

[0069] In this method, during the molding process of the smoke-generating body 100, the paste of the smoke-generating matrix expands and contracts, resulting in some depressions on the surface of the semi-finished smoke-generating body. Furthermore, the clamping operation during the cutting and preparation of the semi-finished smoke-generating body may also create corresponding depressions. These depressions constitute the radially concave backslope described in this application. Such depressions can lead to empty packages after the smoke-generating body is packaged, affecting the user experience. Therefore, when coating the magnetic particles 400, the coating can be applied at the backslope position, which can both fill the outer peripheral surface of the smoke-generating body 100 and achieve reasonable dispersion of the magnetic particles 400, thereby improving the recognition pass rate of the aerosol product and enhancing the structural strength of the smoke-generating body 100. It is understood that filling the smoke-generating body 100, or coating its outer peripheral surface to a predetermined outer diameter, makes its outer diameter more standardized, which is beneficial for subsequent assembly.

[0070] In this embodiment, the magnetic particles 400 are coated by mixing the magnetic particles 400 with food-grade adhesive to form a coating material, and then coating is completed using a coating device.

[0071] In some alternative embodiments, to prevent the absorbent material inside the smoke-generating body 100 from absorbing moisture from the air through the outer first packaging paper and becoming damp, the aerosol product of this application embodiment also has a second packaging paper on the outside of the formed smoke-generating body 100 (including the first packaging paper). This second packaging paper is composed of an impermeable base paper and an ink layer, and 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 body 100 from absorbing moisture from the air through the first and second packaging papers, thus avoiding dampness. This keeps the aerosol product of the present invention aesthetically pleasing and prevents bacteria or mold growth on the surface of the cigarette due to liquid penetration.

[0072] To balance the anti-permeability function with the proper dispersion of the magnetic particles 400, in some embodiments, the magnetic particles 400 are distributed between the radial outer peripheral surface of the smoke generator 100 (i.e., the first packaging paper) and the second packaging paper. To enhance the overall magnetic field effect while reducing the amount of magnetic powder used, in some embodiments, the magnetic domains of the magnetic particles 400 dispersed in the packaging paper 300 are collimated in the direction of the external magnetic field.

[0073] The term "collimated alignment" refers to the fact that the magnetization directions of the magnetic domains within the magnetic particles 400 are forcibly redirected under the influence of an external magnetic field, becoming essentially parallel to the direction of the external magnetic field, thus forming a highly consistent orientation. In the context of aerosol generation systems, the advantage of this alignment is that it makes the magnetic response characteristics of the magnetic particles 400 more consistent and stronger, thereby improving their coupling efficiency with the alternating magnetic field of the induction coil and reducing performance differences and identification errors caused by disordered magnetic domain orientations.

[0074] In this embodiment, after coating but before drying and shaping, a weak magnetic field can be applied to unify the magnetic domain orientation of the magnetic particles 400. This enhances the overall magnetic field effect while reducing the amount of magnetic powder used.

[0075] It is understood that the magnetic domains, magnetic domain orientations, and collimation arrangements in this embodiment are clear and known to those skilled in the art.

[0076] In one embodiment, reference Figures 3 to 8 The arrangement of the magnetic particles 400 on the packaging paper is not limited, that is, the shape and pattern formed by the magnetic particles 400 are not limited. For example, the magnetic particles 400 can be... Figure 3 The circular or arc-shaped pattern shown ( Figure 3 (not shown in the image), or it could be Figure 4 and Figure 5 The spiral-shaped pattern shown can also be Figure 6 , Figure 7 and Figure 8 The elongated pattern shown extends along the axial direction of the smoke-generating body 100.

[0077] In one embodiment, reference Figure 3 The magnetic particles 400 are arranged to form a ring pattern, and at least two (three in this embodiment) ring patterns are spaced apart along the axial direction of the smoke-generating body 100 on the packaging paper 300.

[0078] In one embodiment, reference Figure 6 and Figure 8 The magnetic particles 400 are distributed in a long strip pattern, and the packaging paper 300 has two long strip patterns symmetrically arranged with the axis of the smoke-generating body 100 as the center.

[0079] In one embodiment, reference Figure 6 and Figure 7 The magnetic particles 400 are distributed in a long strip pattern, and the packaging paper 300 has at least three long strip patterns arranged in a circular array around the axis of the smoke-generating body 100.

[0080] It is understood that the pattern formed by the magnetic particles 400 in this application can also be a combination and distribution of the patterns described above.

[0081] From the perspective of differences in magnetic characteristics, several key parameters include permeability, resistivity, and temperature coefficient of resistance.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] In some embodiments, the magnetic particles 400 are made of at least one of the following: elemental iron, elemental nickel, elemental cobalt, iron alloy, nickel alloy, cobalt alloy, iron oxide, cobalt oxide, nickel oxide, ferrite, iron-based / cobalt-based / nickel-based nanocrystalline soft magnetic alloy, permalloy, composite magnetic alloy material, modified graphite, and modified graphene.

[0086] 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.

[0087] 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.

[0088] 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).

[0089] 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.

[0090] 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.

[0091] It should be understood that if the coating of magnetic particles 400 is too thick, the packaging paper 300 will be difficult to roll into a tube or will easily fall off. To avoid falling off, more glue needs to be applied. If there is too much glue, it is easy to produce an odor during subsequent use. Therefore, the coating thickness of magnetic particles 400 needs to be moderate.

[0092] 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.

[0093] In one embodiment, the magnetic particles 400 cover 10% to 100% of the packaging paper 300.

[0094] In this embodiment, the coverage ratio is defined as the ratio of the area of ​​the magnetic particles 400 coated to the area of ​​the packaging paper 300 surrounding the smoke generator 100. In this embodiment, the coverage ratio of the magnetic particles 400 on the packaging paper 300 can be any one of the following values: 10%, 15%, 20%, 30%, 45%, 50%, 60%, 70%, 75%, 80%, 90%, 100%, or any range between two values. The specific value is not limited here.

[0095] It should be understood that the weight per unit area of ​​the magnetic particles 400 coated on the packaging paper 300 also affects the overall magnetic characteristics of the aerosol product.

[0096] In one embodiment, the amount of magnetic particles 400 coated on the packaging paper 300 is 2~100 mg / cm² (milligrams per square centimeter).

[0097] In this embodiment, the coating amount is defined as the ratio of the mass of the magnetic particles 400 to the area of ​​one coated side of the packaging paper 300; in this embodiment, the optional coating amount of the magnetic particles 400 on the packaging paper 300 is 2 mg / cm³. 2 3mg / cm 2 3mg / cm 2 5mg / cm 2 10mg / cm 2 20mg / cm 2 40mg / cm 2 60mg / cm 2 80mg / cm 2 100mg / cm 2 Any one of the values ​​in the range, or any range between the two, with no specific value specified here.

[0098] In one embodiment, the mass ratio of magnetic particle 400 to single magnetic sensor 200 is (0.3~3):1.

[0099] 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 300, resulting in packaging paper 300 with excessive hardness, 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.

[0100] In one embodiment, the magnetic particles 400 have a mass of 6 to 150 mg.

[0101] In this embodiment, the mass of the magnetic particles 400 can be any value from 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 300, resulting in excessively high hardness of the prepared packaging paper 300, 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.

[0102] In one embodiment, reference Figure 1The aerosol product also includes a plug 500, a tube 600, a cooling section 700, and a filter section 800. The filter section 800, the cooling section 700, the smoke generator 100, and the plug 500 are housed in the tube 600, and the plug 500, the smoke generator 100, the cooling section 700, and the filter section 800 are arranged sequentially along the axial direction of the tube 600.

[0103] To further enhance the overall magnetism of the aerosol product, some embodiments further include placing magnetic particles 400 in the plug 500 substrate at one end of the smoke-generating body 100 in the axial direction.

[0104] Understandably, reference Figure 9 By setting a plug 500, the length of the magnetic field region is enhanced in the effective height direction. The plug 500 and the smoke generator 100 are arranged adjacent to each other along 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 a space with a strong magnetic field. 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.

[0105] In this embodiment, the shapes of the smoke-generating body 100 and the plug 500 are not limited; they can be cylinders, cuboids, frustums, or other shapes. The number of plugs 500 is also not limited; there can be one, two, or more. The position of the plugs 500 is also not limited; they can be distributed along the axis of the smoke-generating body 100 at any end of the aerosol product, or at both ends of the aerosol product. Whether the plugs 500 are in contact with the smoke-generating body 100 is not limited; they can be in direct contact or spaced apart.

[0106] The present invention also provides an aerosol generating device, comprising an induction coil, an electronic circuit system, and the aerosol product 100 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.

[0107] 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), by capturing 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, corresponding 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 power input, controlling the remaining heating time, etc.

[0108] 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.

[0109] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any appropriate changes and variations made to the above embodiments within the essential spirit of the present invention fall within the scope of protection claimed by the present invention.
