[0002] Traditional e-cigarettes or low-temperature heated cigarettes mainly rely on barcodes (such as one-dimensional or two-dimensional codes) for anti-counterfeiting identification and reading information such as manufacturer and production date. However, the use of optical recognition systems for barcode recognition is limited by various environmental factors.

[0043] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] In the present invention, when an element is referred to as being "fixed to" another element, unless specifically limited to "directly," it may be directly on the other element or there may be an intervening element. When an element is considered to be "connected" to another element, unless specifically limited to "directly," it may be directly connected to the other element or there may be an intervening element. Conversely, when an element is referred to as being "directly connected" or "directly fixed," there is no such intervening element. The various objects in the drawings of the embodiments are drawn to scale for ease of illustration, rather than to the scale of the actual components.

[0045] The "aerosol-generating product" as used in the embodiments of the present invention refers to a product containing a smoking material that can generate an aerosol, such as smoke or mist, upon heating, such as an aerosol-generating product, a cigarette cartridge, or a cigarette, preferably a disposable product. The aerosol-generating product itself cannot generate electrical energy.

[0046] The "aerosol-generating device" described in the embodiments of the present invention refers to a device used to provide heat or electrical energy to an aerosol-generating article, such as a smoking device. The aerosol-generating device may directly provide heat to heat the aerosol-generating article, or preferably, provide electrical energy to the aerosol-generating article, which then converts the electrical energy into heat to heat the smoking material.

[0047] The "smoking material" described in the embodiments of the present invention refers to a smoking substance that can produce odor and / or nicotine and / or smoke upon heating or combustion, i.e., a substance that can be atomized, i.e., an aerosol-forming substance. Smoking materials can be solid, semi-solid, or liquid. Solid smoking materials are often processed into thin sheets due to considerations such as air permeability, assembly, and manufacturing, and are therefore commonly referred to as thin sheets. Thin sheets are also commonly referred to as thin sheets. The smoking materials discussed in the embodiments of the present invention can be natural or synthetic cigarette liquids, cigarette oils, cigarette glues, cigarette pastes, shredded tobacco, tobacco leaves, etc. For example, synthetic smoking materials contain glycerin, propylene glycol, and nicotine. Smoking liquids are liquids, cigarette oils are oily, cigarette glues are gel-like, and cigarette pastes are paste-like. Shredded tobacco can be natural, synthetic, or processed tobacco, and tobacco leaves can be natural, synthetic, or processed tobacco. The tobacco material can be heated in a form sealed by other substances, such as being stored in a heat-degradable package, such as a microcapsule, and the desired volatile substances are extracted from the degraded or porous sealing package after heating.

[0048] The tobacco materials described in the embodiments of the present invention may or may not contain nicotine. Nicotine-containing tobacco materials may include natural tobacco leaf products, at least one of nicotine-based tobacco liquids, tobacco oils, tobacco glue, tobacco paste, cut tobacco, and tobacco leaves. Tobacco liquid is aqueous, tobacco oils are oily, tobacco glue is gelatinous, and tobacco paste is paste-like. Cut tobacco includes natural, artificial, or extracted tobacco, and tobacco leaves include natural, artificial, or extracted tobacco. Nicotine-free tobacco materials primarily contain flavoring substances, such as spices, which can be atomized to simulate the smoking process and help people quit smoking. In one embodiment, the spices include mint oil. The tobacco materials may also include other additives, such as glycerin and / or propylene glycol.

[0049] The "readable information" described in the embodiments of the present invention includes but is not limited to at least one of the smoke material components, the content of the smoke material components, the most suitable heating method for the aerosol generating product, the model, serial number, manufacturer, sales unit, production date, sales date, expiration date, etc.

[0050] See also Figures 1 to 5 An embodiment of the present invention provides an aerosol generating system 10 , comprising an aerosol generating article 100 and an aerosol generating device 200 .

[0051] The aerosol-generating article 100 includes a cigarette body 110 and a magnetic recording medium 160. The magnetic recording medium 160 serves as an information storage unit and stores readable information. The magnetic recording medium 160 can be disposed on the surface and / or inside the cigarette body 110.

[0052] The cigarette body 110 may include a cigarette material 112 for generating aerosol. The magnetic recording medium 160 may cover the cigarette material 112, be covered by the cigarette material 112, and / or be placed in the cigarette material 112.

[0053] The cigarette body 110 may further include a supporting tube 114 for wrapping the cigarette material 112. The supporting tube 114 may be formed of, for example, cigarette paper or wrapping paper. The magnetic recording medium 160 may be disposed on the inner surface or outer surface of the supporting tube 114. Figure 6 The aerosol generating device 200 is provided with a receiving cavity 204 for receiving the aerosol generating product 100, and the aerosol generating device 200 includes an information reading unit, which includes a magnetic head 260 arranged in the receiving cavity 204 for reading the readable information.

[0054] In this embodiment of the present invention, an information storage unit is provided in the aerosol-generating article 100, and an information reading unit is provided in the aerosol-generating device 200. When the aerosol-generating article 100 is placed in the receiving chamber 204 of the aerosol-generating device 200, the aerosol-generating device 200 can read the information stored in the information storage unit. The information storage unit is a magnetic recording medium, which has a large information storage capacity and can be installed on surfaces of various shapes and substrates, providing greater flexibility and adaptability. Furthermore, the magnetic recording medium is low-cost, simple to install, and easy to implement.

[0055] The read information is preferably transmitted to a display screen provided on the housing of the aerosol generating device 200. The user can verify the authenticity of the aerosol generating article 100 based on the read information, or adjust the method of using the aerosol generating article 100 based on the read information. It is understood that the information stored in the information storage unit is not limited to being read using the information reading unit provided in the aerosol generating device, and other information reading devices can also be used to read the information stored in the information storage unit.

[0056] Preferably, the readable information weakens or disappears when the temperature is greater than a preset temperature, or the magnetic recording medium 160 weakens or demagnetizes when the temperature is greater than a preset temperature. For example, the spontaneous magnetization of the magnetic recording medium decreases when the temperature is greater than a preset temperature, and the spontaneous magnetization decreases with increasing temperature, or even disappears altogether. The preset temperature may be between 100°C and 300°C. When the aerosol-generating article is inhaled, the stored information weakens to the point of being unreadable or even disappears. This ensures that the aerosol-generating article that can be read each time is an unheated aerosol-generating article, eliminating the need to intentionally erase the readable information using other means. This is convenient and effective.

[0057] In some embodiments, the magnetic recording medium 160 may have a quasi-two-dimensional structure, such as a sheet, layer, or film. The magnetic recording medium 160 may be rigid or flexible, for example, having a certain strength but being bendable. The quasi-two-dimensional magnetic recording medium 160 may be further bent or curled, allowing the same volume of the aerosol-generating article 100 to accommodate a larger area of ​​the magnetic recording medium 160.

[0058] The magnetic recording medium 160 may include a magnetic storage material layer 161. Magnetic storage materials are materials that use rectangular hysteresis loops or magnetic moment changes to store information. The magnetic storage material may be in the form of particles (i.e., magnetic powder) or a continuous film.

[0059] The magnetic recording medium 160 may further include a substrate 162. The substrate 162 supports the magnetic storage material layer 161 and may be a layered substrate. The magnetic storage material layer 161 may be stacked on the surface of the substrate 162. The substrate 162 may be made of a non-magnetic material, such as a polymer layer or a non-magnetic metal layer.

[0060] When the magnetic storage material is in granular form, the granular magnetic storage material can be uniformly dispersed on the surface of the substrate 162 to form the magnetic storage material layer 161. For example, the granular magnetic storage material can be mixed with a non-magnetic adhesive, solvent, or the like to form a magnetic slurry, which is then coated on the surface of the substrate 162 to form the magnetic storage material layer 161. The granular magnetic storage material can be at least one of metal oxide magnetic powder and metal magnetic powder. The metal oxide magnetic powder includes but is not limited to at least one of γ-Fe2O3 magnetic powder, Fe3O4 magnetic powder, and CrO2 magnetic powder. The metal magnetic powder includes but is not limited to at least one of Fe magnetic powder, Co magnetic powder, Ni magnetic powder, Fe alloy magnetic powder, Co alloy magnetic powder, and Ni alloy magnetic powder. The granular magnetic storage material can be, for example, acicular in shape.

[0061] When the magnetic storage material is a continuous thin film material, the magnetic storage material layer 161 can be composed of a continuous magnetic storage material. For example, the magnetic storage material layer 161 can be a Co alloy layer. The Co alloy can be, for example, a Co-Ni-P, Fe-Ni-Co, Co-P, or other alloy. The magnetic storage material layer 161 can have a multilayer thin film structure. For example, the magnetic storage material layer can be formed by sandwiching a non-magnetic metal layer between two magnetic metal layers. The intermediate non-magnetic metal layer can generate a demagnetizing coupling effect between the two magnetic metal layers, thereby enabling the two magnetic metal layers to obtain high coercivity. The magnetic storage material layer 161 can be formed on the substrate 162 by electroplating, chemical plating, sputtering, evaporation, or ion plating.

[0062] The readable information can be recorded in the magnetic storage material layer 161 in an encoded manner. Specifically, the binary digital information can be converted into a magnetization reversal form of the magnetic storage material and recorded in the magnetic storage material layer 161. For example, when recording "1", the magnetic storage material changes from an unmagnetized state to a saturated magnetized state in a first direction, and when recording "0", the magnetic storage material changes from an unmagnetized state to a saturated magnetized state in a second direction. The tracks of these information records form magnetic tracks, and the readable information is stored in the magnetic storage material layer 161 along the magnetic tracks.

[0063] See also Figure 2 and Figure 3In some embodiments, the quasi-two-dimensional magnetic recording medium 160 can be wrapped around the entire periphery of the tobacco material 112. For example, the tobacco material 112 can be formed into a rod or bar shape, and the magnetic recording medium 160 can be bent into a cylindrical structure and placed around the entire periphery of the tobacco material 112. In one embodiment, the magnetic recording medium 160 also serves as a support tube, wrapping, supporting, and containing the tobacco material 112 while recording information, eliminating the need for a separate support tube 114.

[0064] In another embodiment, the cigarette body 110 may also include the supporting tube 114 that wraps the entire cigarette material 112. The supporting tube 114 is preferably stacked with the magnetic recording medium 160. Figure 2 As shown, in one embodiment, the supporting tube 114 can be wrapped around the periphery of the magnetic recording medium 160. Figure 3 As shown, in another embodiment, the support tube 114 can be sandwiched between the magnetic recording medium 160 and the entire smoking material 112. In both cases, the support tube 114 is made of non-magnetic material.

[0065] In another embodiment, Figure 4 As shown, the cylindrical magnetic recording medium 160 is disposed within the tobacco material 112. A portion of the tobacco material 112 is disposed within the cylindrical magnetic recording medium 160, while another portion of the tobacco material 112 is disposed outside the magnetic recording medium 160, wrapping the outer surface of the magnetic recording medium 160. The cylindrical magnetic recording medium 160 can be concentrically spaced apart from the support tube 114. Of course, the cylindrical structure of the magnetic recording medium can also be left unfilled with tobacco material 112, for example to accommodate other components, such as support rods.

[0066] See also Figure 5 In other embodiments, the quasi-two-dimensional magnetic recording medium 160 may be in the form of a strip. The support tube 114 may wrap around the entire periphery of the tobacco material 112. The strip-shaped magnetic recording medium 160 may be disposed along the axial direction of the cigarette body 110 on the surface (i.e., the inner and outer surfaces) of the support tube 114 close to or away from the tobacco material 112. In other embodiments, the strip-shaped magnetic recording medium 160 may also be disposed within the tobacco material 112 and wrapped by it.

[0067] In the above-mentioned embodiment, in the case where the magnetic recording medium 160 is disposed on a surface (i.e., inner or outer surface) of the carrier tube 114 close to or away from the tobacco material 112, a magnetic storage material layer 161 can be directly disposed on the inner or outer surface of the carrier tube 114. For example, magnetic slurry can be coated on the inner or outer surface of the carrier tube 114, or the magnetic storage material layer 161, such as a film or alloy layer, can be directly plated or deposited on the inner or outer surface of the carrier tube 114. In this case, the carrier tube 114 can also serve as the substrate 162. Of course, the magnetic storage material layer 161 can also be bonded to the inner or outer surface of the carrier tube 114 via the substrate 162. For example, the surface of the substrate 162 away from the magnetic storage material layer 161 can be bonded to the inner or outer surface of the carrier tube 114.

[0068] Preferably, the magnetic recording medium 160 is disposed on the outer surface of the carrier tube 114. In this case, when the magnetic head 260 reads information stored in the magnetic recording medium 160, the magnetic head 260 is closer to the magnetic recording medium 160, facilitating information reading. Preferably, when the magnetic recording medium 160 is disposed, the distance between the substrate 162 and the axis of the aerosol-generating article 100 is shorter than the distance between the magnetic storage material layer 161 and the axis of the aerosol-generating article 100. This arrangement allows the magnetic head 260 to be closer to the magnetic storage material layer 161 when reading information stored in the magnetic recording medium 160, facilitating information reading. Preferably, the magnetic storage material layer 161 is disposed directly on the carrier tube 114, that is, the carrier tube 114 serves as the substrate for the magnetic storage material layer 161. This arrangement is simpler, not only conserves raw materials but also simplifies the manufacturing process of the aerosol-generating article 100.

[0069] See also Figure 6 The information reading unit of the aerosol generating device may include a magnetic head 260 for reading information. The aerosol generating device 200 may include a housing, which may define a housing cavity 204 for accommodating the aerosol generating article 100. The magnetic head 260 may be disposed in the housing cavity 204. Furthermore, the magnetic head 260 may be positioned such that, when the aerosol generating article 100 is inserted into the cavity, it is aligned with the magnetic track of the magnetic recording medium 160. The magnetic head 260 may not contact the magnetic recording medium 160, as long as the distance between the magnetic head 260 and the magnetic recording medium 160 is within the effective sensing distance range of the magnetic head 260.

[0070] The primary function of the magnetic head 260 is to achieve electromagnetic energy conversion. In one embodiment, the magnetic head 260 includes a gapped annular magnetic core and a coil wound around the annular magnetic core. The magnetic recording medium can affect the magnetic field of the gap in the magnetic head, thereby causing a change in the current in the coil, thereby converting the readable information in the magnetic recording medium into an electrical signal output. The material of the magnetic core is preferably a soft magnetic material with high magnetic permeability. The material of the magnetic core can be, for example, one or more of an alloy core material, a ferrite core material, an amorphous core material, and a microcrystalline thin film core material. The alloy core material can be, for example, a molybdenum permalloy material or a Sendai-based core material.

[0071] See also Figure 7 In one embodiment, the aerosol-generating device 200 further includes a drive unit configured to drive relative movement between the magnetic head and the aerosol-generating article. For example, the aerosol-generating device 200 further includes a magnetic head drive unit 270 configured to drive relative movement of the magnetic head 260 relative to the magnetic recording medium 160, thereby reading readable information stored on the magnetic recording medium 160. When the magnetic recording medium 160 is a cylindrical structure, the magnetic head drive unit 270 can drive the magnetic head 260 to rotate circumferentially around the aerosol-generating article 100 to read information. When the magnetic recording medium 160 is configured as a strip extending axially of the aerosol-generating article 100, the magnetic head drive unit 270 can drive the magnetic head 260 to move axially along the aerosol-generating article 100 to read information. The head driving unit 270 may include a driving device and a transmission device. The head 260 may be connected to the driving device via the transmission device. The transmission device may include at least one of a crank slider mechanism, a swing guide rod mechanism, an eccentric wheel mechanism, a hinge connecting rod mechanism, a gear rack mechanism, etc.

[0072] Of course, in the embodiment where a drive unit drives the aerosol-generating article 100 to move relative to the magnetic head 260, the drive unit may also be an aerosol-generating article drive unit, connected to the aerosol-generating article, and driving the aerosol-generating article to rotate circumferentially or move axially of the accommodating cavity. The movement of the aerosol-generating article 100 causes the magnetic head 260 to rotate circumferentially or move axially relative to the aerosol-generating article 100 to read information.

[0073] In one embodiment, the aerosol generating device 200 further includes a control unit 230, which can be electrically connected to the magnetic head 260 and configured to receive information transmitted by the magnetic head 260. The aerosol generating device 200 can also include a display unit 280, on which the control unit 230 can transmit the information transmitted by the magnetic head 260 for display. The control unit 230 can further be connected to a magnetic head driving unit 270 to control the movement path of the magnetic head 260. The magnetic head driving unit 270, the control unit 230, and the display unit 280 can be disposed on the housing.

[0074] In one embodiment, multiple magnetic heads 260 may be positioned at different locations within the accommodating cavity 204. When the magnetic recording medium 160 is cylindrical, multiple magnetic heads 260 may be positioned axially along the accommodating cavity 204. When the magnetic recording medium 160 is configured as a strip extending axially along the aerosol-generating article 100, multiple magnetic heads 260 may be positioned axially along the accommodating cavity 204. By providing multiple magnetic heads 260, when the aerosol-generating article 100 is not installed in the accommodating cavity 204 as configured, the magnetic head 260 closest to the magnetic recording medium can be used to read information, thereby avoiding situations where the magnetic recording medium cannot correspond to the magnetic head 260. Multiple tracks may be provided on the magnetic recording medium corresponding to the multiple magnetic heads 260, or multiple magnetic recording media 160 may be provided on the aerosol-generating article 100 corresponding to the multiple magnetic heads 260. The multiple magnetic recording media 160 may store the same or different readable information.

[0075] See also Figure 6 The aerosol-generating article 100 according to embodiments of the present invention may further include an electrically powered heating element 120 disposed adjacent to the tobacco material 112 and capable of heating the tobacco material 112. The electrically powered heating element 120 converts electrical energy into thermal energy and may encase, be encased by, and / or be positioned within the tobacco material 112. By disposing the electrically powered heating element 120 within the tobacco body 110, i.e., by making the electrically powered heating element 120 an integral component of the aerosol-generating article 100, better and more complete contact between the tobacco material 112 and the electrically powered heating element 120 can be achieved during the manufacturing process of the aerosol-generating article 100, thereby improving heating efficiency. The electrically powered heating element 120 may have a variety of shapes and structures and does not need to be highly strong enough to withstand the pressure of multiple insertions into the tobacco material 112.

[0076] The aerosol-generating article 100 can be disposable, and thus the electrically powered heating element 120 can also be disposable, thus avoiding issues associated with repeated use of the electrically powered heating element 120, such as contamination and accumulation of harmful substances caused by substances such as tar remaining on the surface of the electrically powered heating element 120, which are difficult to remove. In one embodiment, the aerosol-generating article 100 is a disposable cigarette.

[0077] Preferably, the electrically conductive heating element 120 has a quasi-two-dimensional structure, such as a sheet, layer, or film, thereby having a large surface area. The electrically conductive heating element 120 with a quasi-two-dimensional structure can be rigid or flexible, for example, it can have a certain strength but bendable. The electrically conductive heating element 120 with a quasi-two-dimensional structure can be further bent or curled, so that a larger area of ​​the electrically conductive heating element 120 can be accommodated within the same volume of the aerosol-generating article 100. The thickness of the electrically conductive heating element 120 with a quasi-two-dimensional structure can be 1 nanometer to 1 millimeter, in one embodiment, 500 nanometers to 500 micrometers, and in another embodiment, 1 micrometer to 130 micrometers.

[0078] The materials for preparing the electrically heated heating element 120 may include, but are not limited to, carbon nanotubes, carbon nanotube films, graphene, carbon fibers, carbon fiber films, carbon films, carbon fiber cloths, metals, alloys and metal compounds that generate heat when electrically heated, including gold, silver, copper, aluminum, nickel, chromium, iron, stainless steel, nickel-chromium alloys, metal oxides, iron-chromium-aluminum alloys, palladium alloys and amorphous metal alloys, as well as one or more of other derivatives and compounds with carbon as a constituent element.

[0079] In other embodiments, the material used to make the electrically conductive heating element includes a solid composite material. The solid composite material may be composed of two or more substances with different physical and chemical properties. One of the substances may be a conductive substance containing a metal, semiconductor, conductive polymer, alloy, or carbon material, and the other substances may include, but are not limited to, resins, rubber, ceramics, fibers, and synthetic polymer compounds. Examples include silicone rubber, rubber and conductive polymer composites, carbon fiber and graphene composites, conductive polymer and ceramic composites, carbon fiber paper (composite of chopped carbon fiber with pulp and other polymer additives), carbon paper (composite of carbon powder or graphite powder with pulp and other additives), and polyimide heating film. Polyimide heating film is also known as polyimide film.

[0080] See also Figure 8 and Figure 9In one embodiment, the two-dimensionally shaped electrically heated element 120 is wrapped around the entirety of the tobacco material 112, forming a cylindrical structure. The electrically heated element 120 itself can also function as cigarette paper or a supporting tube, wrapping, supporting, and containing the tobacco material 112 while electrically heating it. Of course, the aerosol generating device 200 can also include a separate supporting tube 114, which can wrap around the electrically heated element 120 or be sandwiched between the electrically heated element 120 and the entirety of the tobacco material 112. In the latter case, the supporting tube 114 preferably has good thermal conductivity.

[0081] In another embodiment, the quasi-two-dimensional electrically-heating element 120 is disposed in a spiral shape within the smoking material 112. For example, the aerosol-generating article 100 may be manufactured using a method similar to that of cigarettes, where the smoking material 112 is first formed into a smoking material 112 sheet, the quasi-two-dimensional electrically-heating element 120 is superimposed on the smoking material 112 sheet to form a laminated structure, and the laminated structure is then rolled into a rod or bar shape, thereby obtaining the spirally-shaped electrically-heating element 120 within the smoking material 112.

[0082] It is understood that the energized heating element 120 is not limited to a two-dimensional structure, and may include, for example, one or more one-dimensional structures, such as a heating rod, a heating bar, or a heating wire.

[0083] In one embodiment, the electrically heated element 120 includes an electrically heated material uniformly mixed with the tobacco material 112. The electrically heated material is in the form of powder, flakes, granules, or short fibers. The electrically heated material is mixed with the tobacco material 112 and interconnected to form a conductive pathway, allowing current to be more evenly introduced into the aerosol-generating article 100, thereby uniformly heating a localized area of ​​the tobacco material 112. The size of the electrically heated material can range from 10 nanometers to 5 millimeters. The electrically heated material can be, for example, metal or alloy powder or debris, or conductive carbon material, such as carbon nanotubes, graphene, carbon fibers, amorphous carbon, or graphite particles or powder.

[0084] There can be various positional relationships between the magnetic recording medium 160 and the electrically heated element 120. For example, the magnetic recording medium 160 and the electrically heated element 120 can be arranged in a superimposed or spaced relationship. The magnetic recording medium 160 and the electrically heated element 120 can be in contact with or not in contact with each other.

[0085] When the magnetic recording medium 160 and the electrically heated element 120 are stacked, the magnetic recording medium 160 can be attached to the surface of the cylindrical electrically heated element 120. For example, the side of the substrate 162 of the magnetic recording medium 160 away from the magnetic storage material layer 161 can be attached to the surface of the cylindrical electrically heated element 120 using an adhesive or other means. Alternatively, the magnetic storage material layer 161 can be directly formed on the surface of the electrically heated element 120 by coating, plating, or spraying, thereby directly forming the magnetic recording medium 160. In other words, the electrically heated element 120 can serve as the substrate of the magnetic recording medium 160.

[0086] See also Figure 8 and Figure 10 In one embodiment, the magnetic recording medium 160 and the electrically heated element 120 are both cylindrical structures, and the magnetic recording medium 160 is stacked on the outer surface of the cylindrical electrically heated element 120. Figure 9 In another embodiment, the magnetic recording medium 160 and the electrically powered heating element 120 are both cylindrical structures, and the magnetic recording medium 160 is stacked on the inner surface of the cylindrical electrically powered heating element 120. When the magnetic recording medium 160 is stacked on the outer surface of the cylindrical electrically powered heating element 120, the magnetic head 260 can be closer to the magnetic recording medium 160 when reading information, thereby facilitating information reading.

[0087] See also Figure 11 In another embodiment, the magnetic recording medium 160 may have a strip-shaped structure, and the electrically heated element 120 may have a cylindrical structure. The strip-shaped magnetic recording medium 160 may be disposed on the inner or outer surface of the electrically heated element 120 along the axial direction of the aerosol-generating article. When the strip-shaped magnetic recording medium 160 is stacked on the outer surface of the cylindrical electrically heated element 120, the magnetic head 260 can be closer to the magnetic recording medium 160 when reading information, thereby facilitating information reading.

[0088] Since the magnetic recording medium 160 is directly arranged on the surface of the energized heating element 120, when the aerosol generating product 100 is inhaled, as the energized heating element 120 generates heat, the magnetic recording medium 160 will gradually demagnetize, and no readable information will be stored. In this way, it can be ensured that each time the aerosol generating product can read information, it is the first time it is used.

[0089] The two stacked magnetic recording media 160 and the electrically heated element 120 can be used as the carrier tube 114 of the aerosol-generating article 100 , eliminating the need for a separate carrier tube 114 .

[0090] In another embodiment, the cylindrical structure of the electric heating element 120 can also be directly used as the supporting tube of the aerosol generating product 100, and the cylindrical structure or strip structure of the magnetic recording medium 160 can also be arranged in the inner cavity of the electric heating element 120 and wrapped by the tobacco material 112. The electric heating element 120 and the magnetic recording medium 160 can be arranged at intervals.

[0091] In one embodiment, the electrically heated element 120 can be made of a material having both electrothermal and magnetic properties, or a mixture of a material having electrothermal and magnetic properties. This allows the electrically heated element 120 to simultaneously function as the magnetic recording medium 160, simplifying the preparation of the aerosol-generating article. The material having both electrothermal and magnetic properties can be, for example, a Co alloy layer, and the Co alloy can be, for example, a Co-Ni-P, Fe-Ni-Co, or Co-P alloy. It should be understood that when the electrically heated element 120 and the magnetic recording medium 160 are two independent layers, the electrically heated element 120 can be made of a non-magnetic material to prevent the electrically heated element 120 from shielding or affecting the magnetic head's induction of the magnetic recording medium 160.

[0092] The aerosol-generating device 200 also includes device electrodes, such as a first device electrode 222 and a second device electrode 224, disposed within the accommodating cavity 204 for supplying power to the electrically powered heating element 120. Theoretically, simply connecting both ends of the electrically powered heating element 120 to the device electrodes of the aerosol-generating device 200 can power the electrically powered heating element 120, thereby achieving electrically heated tobacco material 112. For example, when the electrically powered heating element 120 is cylindrical and wrapped around the tobacco material 112, the portion of the electrically powered heating element 120 that faces the device electrodes can directly contact the device electrodes, thereby achieving electrical connection. To enhance electrical connection with the device electrodes, the aerosol-generating article 100 may include product electrodes, such as a first product electrode 122 and a second product electrode 124. The product electrodes may be made of a material with a higher electrical conductivity than the electrically powered heating element 120 and may be in the form of a layer, film, filament, sheet, or block. The product electrodes may be welded to the electrically powered heating element 120, fixedly connected by snaps, or bonded with conductive adhesive. Alternatively, the product electrode can also be formed on the surface of the energized heating element 120 by coating, spraying or printing.

[0093] To facilitate mutual contact and electrical connection between the device electrode of the aerosol-generating device 200 and the product electrode of the aerosol-generating article 100, the position of the device electrode in the receiving cavity 204 corresponds to the position of the product electrode on the aerosol-generating article 100, so that the device electrode and the product electrode face each other when the aerosol-generating article 100 is placed in the aerosol-generating device 200. More preferably, the dimensions of the aerosol-generating article 100, such as the radial dimensions, match the dimensions of the receiving cavity 204, such that the device electrode and the product electrode can contact each other during initial use.

[0094] See also Figure 6 and Figure 10 In one embodiment, the aerosol-generating article 100 has a cylindrical structure, and the first article electrode 122 and the second article electrode 124 are annular structures disposed circumferentially along the cylindrical structure. The electrically conductive heating element 120 has a cylindrical structure, and the first article electrode 122 and the second article electrode 124 are disposed at opposite ends of the cylindrical structure in the axial direction, extending circumferentially around the aerosol-generating article 100. This ensures that current flows uniformly across all locations of the electrically conductive heating element 120, thereby achieving uniform temperature. Correspondingly, the housing of the aerosol-generating device 200 includes a cylindrical sidewall 202 for defining the accommodating chamber 204. The device electrodes include a first device electrode 222 and a second device electrode 224 in an annular structure, which are circumferentially disposed on the inner surface of the cylindrical sidewall 202. The axial positions of the first device electrode 222 and the second device electrode 224 in the accommodating chamber 204 correspond to the positions of the first product electrode 122 and the second product electrode 124. Therefore, when the aerosol-generating article 100 is disposed in the aerosol-generating device 200, the first device electrode 222 is directly opposite the first product electrode 122, and the second device electrode 224 is directly opposite the second product electrode 124. The outer diameters of the annular first and second product electrodes 122, 124 are equal to or slightly smaller than the inner diameters of the annular first and second device electrodes 222, 224.

[0095] In this embodiment, the magnetic recording medium 160 may also be configured as an annular or cylindrical structure and extend circumferentially around the aerosol-generating article 100. The magnetic head 260 may rotate around the circumference of the aerosol-generating article 100 when reading information, preventing the magnetic head 260 from approaching the article electrodes and / or the device electrodes during rotation. During inhalation of the aerosol-generating article, the temperature near the electrodes is generally high, potentially damaging the magnetic head 260. Preferably, the magnetic recording medium 160 may be disposed midway between the first article electrode 122 and the second article electrode 124, and spaced apart from the first article electrode 122 and the second article electrode 124.

[0096] See also Figure 12 In another embodiment, the aerosol-generating article 100 further includes an insulating layer 140 for separating the smoking material 112 into different regions. The product electrodes of the aerosol-generating article 100 include multiple pairs of product electrodes, each consisting of a first product electrode 122 and a second product electrode 124. The energized heating element 120 also includes multiple sub-heating elements 120', each of which is connected to a product electrode pair, for heating the smoking material 112 in different regions. Each region includes its own sub-heating element 120' and product electrode pair. Correspondingly, the device electrodes include multiple pairs of device electrode pairs, each consisting of a first device electrode 222 and a second device electrode 224, disposed at different locations and independently controllable. The positions of the multiple product electrode pairs correspond one-to-one with the positions of the multiple device electrode pairs, allowing heating of different regions of the smoking material 112. The magnetic recording medium 160 may also include multiple sub-recording media 160' disposed in different regions, thereby recording information about the smoking material in different regions. The aerosol generating device 200 may also be provided with multiple sub-magnetic heads 260' corresponding to the multiple sub-recording media 160', thereby separately reading the smoking material information from different regions. In one embodiment, the thermal insulation layer 140 extends radially, separating the smoking material 112 into multiple regions in the axial direction of the aerosol generating article 100. In another embodiment, the thermal insulation layer 140 extends axially, separating the smoking material 112 into multiple regions in the radial direction of the aerosol generating article 100.

[0097] See also Figure 11 、 Figures 13 to 15 In one embodiment, the first and second product electrodes 122, 124 extend axially along the aerosol-generating article 100. For example, the axial directions of the first and second product electrodes 122, 124 are parallel to the axial direction of the aerosol-generating article 100, so that the cylindrical electrically heated element 120 is electrically conductive along its circumference. The first and second product electrodes 122, 124 correspond in position to the device electrodes of the aerosol-generating device 200, for example, the first and second device electrodes 222, 224. Preferably, the first and second product electrodes 122, 124 are spaced apart from each other and disposed at opposite radial ends of the cylindrical electrically heated element 120. The first and second device electrodes 222, 224 are spaced apart from each other and disposed at opposite radial ends of the cylindrical sidewall 202. The shapes of the first and second device electrodes 222, 224 can correspond to those of the first and second product electrodes 122, 124, respectively. For example, the axial directions of the first and second device electrodes 222, 224 are parallel to the axial direction of the cylindrical sidewall 202, and their lengths are substantially the same as those of the product electrodes.

[0098] In this case, the magnetic recording medium 160 can be configured as a strip-shaped structure extending axially along the aerosol-generating article 100. The magnetic head 260 can move axially along the aerosol-generating article 100 when reading information, preventing the magnetic head 260 from approaching the electrodes during rotation. During inhalation of the aerosol-generating article, the temperature near the electrodes is generally high, which may damage the magnetic head 260. The magnetic recording medium 160 can be positioned midway between the first article electrode 122 and the second article electrode 124, and spaced apart from the first article electrode 122 and the second article electrode 124.

[0099] It can be understood that the positions of the first product electrode 122 and the second product electrode 124 can be determined according to the material and structure of the energized heating element 120 and the electrical connection method with the power supply unit 210 .

[0100] The aerosol generating device 200 may further include a power supply unit 210 for providing direct current (DC), such as a battery or a socket for connecting to an external power source. The positive and negative electrodes of the power supply unit 210 are electrically connected to the first device electrode 222 and the second device electrode 224, respectively, via wires 240. The control unit 230 may be configured to control the voltage and / or current supplied by the power supply unit 210 to the device electrodes, such as the first device electrode 222 and / or the second device electrode 224, to implement a switching function and / or a heating and temperature regulation function. The power supply unit 210 and the control unit 230 may be disposed within a housing.

[0101] The aerosol generating article 100 may further include a filter 130 , which is disposed at one axial end of the cigarette body 110 and located at the airflow outflow end, and the other axial end of the cigarette body 110 is the airflow inflow end.

[0102] It is understood that the magnetic recording medium 160 is not limited to covering the tobacco material 112, being covered by the tobacco material 112, and / or being placed in the tobacco material 112, or being disposed on the inner or outer surface of the supporting tube 114. In one embodiment, the magnetic recording medium 160 can be disposed in the filter 130 or on the surface of the filter 130.

[0103] In one embodiment, the housing has an opening communicating with the accommodating cavity 204 , so as to allow the aerosol-generating article 100 to be inserted into the accommodating cavity 204 from the opening.

[0104] It can be understood that the above embodiments can be combined with each other, and the aerosol generating article 100 can simultaneously include two or more energized heating elements 120 and / or information storage units of different embodiments.

[0105] In addition to being applicable to electronic cigarettes and low-temperature heated cigarettes, the aerosol-generating products of the embodiments of the present invention can also be applied to other devices that require heating of specific materials, including but not limited to electrically heated hookahs and pipes.

[0106] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0107] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
