[0022] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. Embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of the present application in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0024] It can be understood that the terms "first", "second", etc. used in the present application can be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0025] It can be understood that for the "connection" in the following embodiments, if there is an electrical signal or data transfer between the connected circuits, modules, units, etc., it should be understood as "electrically connected", "communicatively connected", etc.

[0026] It can be understood that "at least one" means one or more, and "a plurality" means two or more. "At least a part of an element" means a part or all of the element.

[0027] As used herein, the singular forms "a", "an" and "the" may also include the plural forms unless the context clearly dictates otherwise. It should also be understood that the terms "comprise / include" or "have" etc. specify the presence of the stated features, wholes, steps, operations, components, parts or combinations thereof, but do not preclude the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof. At the same time, the term "and / or" used in this specification includes any and all combinations of the related listed items.

[0028] In one embodiment, there is provided an aerosol-generating article, as Figure 1 shown, comprising a filter section, a functional section, a medium section and an identifiable section arranged in sequence. The medium section generates aerosol after being heated. The functional section is used to cool the aerosol generated by the medium section and then transmit it to the filter section, and the filter section outputs the filtered aerosol. The identifiable section has characteristic parameters that can be recognized by an aerosol-generating device, and different types of aerosol-generating articles have different characteristic parameters. Thus, the aerosol-generating device can determine the type of the aerosol-generating article according to the recognized characteristic parameters of the identifiable section, which is convenient for subsequent targeted heating of the aerosol-generating article according to the type of the aerosol-generating article, reducing the safety hazard caused by the mismatch between the aerosol-producing device and the aerosol-generating article. Moreover, the aerosol-generating device can match corresponding heating methods for different types of aerosol-generating articles, with high usability, which is also beneficial to improving the taste of the aerosol and reliable in operation.

[0029] Specifically, the filter section, the functional section, the medium section and the identifiable section are arranged in sequence, which means that the filter section, the functional section, the medium section and the identifiable section are arranged in sequence in the direction from the proximal lip end to the distal lip end. Two adjacent structures can be directly connected or arranged with a gap, which is not limited herein. Exemplarily, in this embodiment, two adjacent structures are directly connected, the medium section is connected to the functional section and the identifiable section, and the filter section is connected to the side of the functional section away from the medium section.

[0030] The aerosol-generating article is for use in conjunction with an aerosol-generating device. After the aerosol-generating article is inserted into the aerosol-generating device, the aerosol-generating device heats the aerosol-generating article. After the medium section of the aerosol-generating article is heated, a relatively high-temperature aerosol is generated. After passing through the cooling of the functional section, it enters the filtering section, where it is filtered to adsorb some large particulate matter, and then the filtered aerosol at an appropriate temperature is output for the user to use.

[0031] After the aerosol-generating article is heated, the medium section may deform (shrink), posing a risk of detachment. In addition, after the aerosol-generating article is used, a low-pressure area is generated at the distal end away from the lip, which may cause the aerosol to flow back and condense during the use interval, thereby contaminating the aerosol-generating device. In this embodiment, by providing an identifiable section on the side of the medium section away from the user, the detachment of the medium section can be prevented, and the contamination of the aerosol-generating device by the reflux aerosol can also be blocked, thereby achieving the purpose of easy cleaning.

[0032] In addition, the identifiable section has characteristic parameters that can be recognized by the aerosol-generating device, and different types of aerosol-generating articles have different characteristic parameters. After the aerosol-generating article is inserted into the aerosol-generating device, the aerosol-generating device can recognize the characteristic parameters of the identifiable section of the inserted aerosol-generating article. Since different types of aerosol-generating articles have different characteristic parameters, the aerosol-generating device can determine the type of the inserted aerosol-generating article according to the recognized characteristic parameters. The type of the identifiable section is not unique, as long as it can identify different types of aerosol-generating articles. The type of the characteristic parameters corresponds to the structure and type of the identifiable section.

[0033] Extendably, in one embodiment, the aerosol-generating device stores the correspondence between different types of aerosol-generating articles and heating methods. After determining the type of the aerosol-generating article, the heating method corresponding to the inserted aerosol-generating article is matched from the stored correspondence, and then the heating parameters are determined according to the matched heating method, and the aerosol-generating article is heated according to the heating parameters, thereby improving the quality of the generated aerosol and preventing problems such as device damage caused by the mismatch between the aerosol-generating article and the aerosol-generating device. In addition, different types of aerosol-generating articles can be adapted to the same aerosol-generating device, and there is no need to carry multiple aerosol-generating devices during use, which is convenient to use.

[0034] In one embodiment, in one embodiment, as Figure 1 shown, the identifiable section includes a plug and a wrapping layer, and the plug and / or the wrapping layer have identifiable characteristic parameters.

[0035] Specifically, the wrapping layer can be disposed on the outer surface of the plug member. Further, it can be partially or entirely wrapped around the plug member. In addition, the wrapping layer can be disposed not only on the outer surface of the plug member, but also on the outer surface of one or more of the medium section, the functional section, and the filtering section. As Figure 1 shown, when the wrapping layer is disposed on the outer surfaces of the filtering section, the functional section, the medium section, and the plug member, these components can be wrapped, serving functions such as fixing the structure, providing protection, and facilitating the installation of the aerosol-generating article.

[0036] The plug member can have recognizable characteristic parameters. After the recognizable section is inserted into the aerosol-generating device, the aerosol-generating device determines the type of the aerosol-generating article by recognizing the characteristic parameters of the plug member.

[0037] Alternatively, the wrapping layer can have recognizable characteristic parameters. When the wrapping layer is disposed to wrap the outer surface of the plug member, after the recognizable section is inserted into the aerosol-generating device, the aerosol-generating device can recognize the characteristic parameters of the wrapping layer from multiple directions, improving the detection sensitivity.

[0038] Alternatively, both the plug member and the wrapping layer can have recognizable characteristic parameters. After the recognizable section is inserted into the aerosol-generating device, the aerosol-generating device can determine the type of the aerosol-generating article more quickly and accurately by recognizing the characteristic parameters.

[0039] In addition, the recognizable section can be a hollow structure to facilitate gas exchange. In this embodiment, when the recognizable section includes the plug member and the wrapping layer, there is a gap between the plug member and the wrapping layer to facilitate gas exchange. The plug member can be made of acetate fiber material.

[0040] In this embodiment, the recognizable section includes the plug member and the wrapping layer, and the plug member and / or the wrapping layer have recognizable characteristic parameters. Multiple structural settings can enable the aerosol-generating article to have characteristic parameters of recognizable types.

[0041] In one embodiment, the recognizable section is a resistance section, and the characteristic parameter of the resistance section is resistivity. The recognizable section includes a conductive metal, or a non-metallic material, or a semiconductor material, or a mixture of a polymer material and a conductive metal, or a mixture of a polymer material and a non-metallic material, or a mixture of a polymer material and a semiconductor material. Different aerosol-generating articles have resistance sections with different resistivities, and the aerosol-generating device recognizes the resistivity of the resistance section of the aerosol-generating article to determine the type of the aerosol-generating substrate that matches the recognized resistivity.

[0042] Specifically, when the resistance section includes a conductive metal, it can include a conductive metal made of one or more materials such as gold, silver, copper, iron, cobalt, nickel, aluminum, tungsten, platinum, lead, germanium, etc. and their corresponding alloys. The resistivity of the resistance section made of such materials is 1.4×10 -8Ω·m - 5.1×10 -4 Ω·m.

[0043] When the resistance segment includes non-metallic materials, it may include one or more non-metallic materials such as graphite, graphene, carbon powder, silicon, etc. and their mixtures, and the resistivity is 0.7×10 -8 Ω·m - 6.4×10 2 Ω·m.

[0044] When the resistance segment includes semiconductor materials, it may include the composition of one or more semiconductor materials such as TiO2, NiO, ZnO, ZnInS, CdS, C3N4, etc. The resistivity of the resistance segment made of such materials is 1.0×10 -4 Ω·m - 2.0×10 2 Ω·m.

[0045] When the resistance segment includes a mixture of a polymer material and a conductive metal, the polymer material can be a thermoplastic or thermosetting polymer material. For example, the material of the resistance segment can be a uniform mixture of polymer materials such as polyethylene terephthalate, polylactic acid, polypropylene, acetate fiber, epoxy resin, etc. and conductive metals such as gold, silver, copper, iron, cobalt, nickel, aluminum, tungsten, platinum, lead, germanium, etc. and their corresponding alloys, and is prepared by extrusion, film pressing, hot pressing or injection molding. The resistivity of the resistance segment made of such materials is 7.5×10 -8 Ω·m - 9.3×10 -4 Ω·m. Or, the material of the resistance segment can be that conductive metals such as gold, silver, copper, iron, cobalt, nickel, aluminum, tungsten, platinum, lead, germanium, etc. and their corresponding alloys are uniformly attached to the surfaces of polymer materials such as polyethylene terephthalate, polylactic acid, polypropylene, acetate fiber and epoxy resin. The resistivity of the resistance segment made of such materials is 4.5×10 -8 Ω·m - 6.8×10 -4 Ω·m.

[0046] When the resistance segment includes a mixture of a polymer material and a semiconductor material, the material of the resistance segment can be a uniform mixture of polymer materials such as polyethylene terephthalate, polylactic acid, polypropylene, acetate fiber, epoxy resin, etc. and semiconductor materials such as TiO2, NiO, ZnO, ZnInS, CdS, C3N4, etc., and is prepared by extrusion, film pressing, hot pressing or injection molding. The resistivity of the resistance segment made of such materials is 3.5×10 -4 Ω·m - 5.5×10 2 Ω·m. Or, the material of the resistance segment can be that semiconductor materials such as TiO2, NiO, ZnO, ZnInS, CdS, C3N4, etc. are uniformly attached to the surfaces of polymer materials such as polyethylene terephthalate, polylactic acid, polypropylene, acetate fiber and epoxy resin. The resistivity of the resistance segment made of such materials is 1.5×10 -4Ω·m - 2.7×10 2 Ω·m.

[0047] For the above-mentioned polyethylene terephthalate, polylactic acid, polypropylene, acetate fiber and epoxy resin, other thermoplastic or thermosetting polymer materials can also be selected. For the above-mentioned conductive metals, other conductive metals can also be selected in addition to gold, silver, copper, iron, cobalt, nickel, aluminum, tungsten, platinum, lead, germanium and their alloys. For the above-mentioned semiconductor materials, other semiconductor materials can also be selected in addition to TiO2, NiO, ZnO, ZnInS, CdS, C3N4.

[0048] In this embodiment, various types of resistance segments are provided, and the specific composition of the resistance segment can be determined according to actual needs.

[0049] In one embodiment, the recognizable segment is a magnetic permeability segment, and the characteristic parameter of the recognizable segment is magnetic permeability. The recognizable segment includes a magnetoconductive material, or includes graphite, or includes a mixture of a polymer material and a magnetoconductive material. Different aerosol-generating articles have magnetic permeability segments with different magnetic permeabilities, and the aerosol-generating device identifies the magnetic permeability of the magnetic permeability segment of the aerosol-generating article, thereby determining the type of aerosol-generating substrate that matches the identified magnetic permeability.

[0050] Specifically, when the magnetic permeability segment includes a magnetoconductive material, it can include iron, cobalt, nickel and their corresponding alloys, and the magnetic permeability of the magnetic permeability segment made of such materials is 20 - 1000×10 -6 H / m; the material of the magnetic permeability segment can also be aluminum and its alloys, and the magnetic permeability of the magnetic permeability segment made of such materials is 1 - 20 ×10 -6 H / m.

[0051] When the magnetic permeability segment includes graphite, the magnetic permeability is 0.1 - 2×10 -6 H / m.

[0052] When the magnetic permeability segment includes a mixture of a polymer material and a magnetoconductive material, the magnetic permeability segment can be prepared by uniformly mixing polyethylene terephthalate with magnetoconductive materials such as iron, cobalt, nickel and their alloys, and then by extrusion, film pressing, hot pressing or injection molding. The magnetic permeability of the magnetic permeability segment made of such materials is 100 - 600×10 -6 H / m.

[0053] Alternatively, the magnetic permeability segment can be prepared by uniformly mixing polylactic acid with magnetoconductive materials such as iron, cobalt, nickel and their alloys, and then by extrusion, film pressing, hot pressing or injection molding. The magnetic permeability of the magnetic permeability segment made of such materials is 200 - 900×10 -6 H / m.

[0054] Alternatively, the permeability section can be prepared by uniformly mixing polypropylene with ferromagnetic materials such as iron, cobalt, nickel and their alloys, and then extruding, film pressing, hot pressing or injection molding. The permeability of the permeability section made of such materials is 50 - 600×10 -6 H / m.

[0055] Alternatively, the permeability section can be prepared by uniformly mixing cellulose acetate with ferromagnetic materials such as iron, cobalt, nickel and their alloys, and then extruding, film pressing, hot pressing or injection molding. The permeability of the permeability section made of such materials is 100 - 700×10 -6 H / m.

[0056] Alternatively, the permeability section can be prepared by uniformly mixing epoxy resin with ferromagnetic materials such as iron, cobalt, nickel and their alloys, and then extruding, film pressing, hot pressing or injection molding. The permeability of the permeability section made of such materials is 10 - 500×10 -6 H / m.

[0057] Alternatively, the permeability section can be prepared by uniformly attaching ferromagnetic materials such as iron, cobalt, nickel and their alloys to the surfaces of polymer materials such as polyethylene terephthalate, polylactic acid, polypropylene, cellulose acetate and epoxy resin. The permeability of the permeability section made of such materials is 20 - 700×10 -6 H / m.

[0058] Other thermoplastic or thermosetting polymer materials can also be selected for the above polyethylene terephthalate, polylactic acid, polypropylene, cellulose acetate and epoxy resin. Other ferromagnetic materials can also be selected in addition to iron, cobalt, nickel and their alloys for the above ferromagnetic materials.

[0059] In this embodiment, multiple types of permeability sections are provided, and the specific composition of the permeability section can be determined according to actual needs.

[0060] Extensibly, if the identifiable section is a resistance section and the wrapping layer has identifiable characteristic parameters, the wrapping layer can be a resistance layer, and the resistivity of the resistance layer in different types of aerosol generating articles is different. If the identifiable section is a permeability section and the wrapping layer has identifiable characteristic parameters, the wrapping layer can be a permeability layer, and the permeability of the permeability layer in different types of aerosol generating articles is different.

[0061] It can be understood that in other embodiments, the identifiable section can also be an integrated structure, for example, composed only of resistance materials or only of permeability materials, which is convenient for manufacturing.

[0062] In one embodiment, the filter section, the functional section, the medium section and the identifiable section are all cylindrical sections, and the filter section, the functional section, the medium section and the identifiable section are connected in sequence. When the filter section, the functional section, the medium section and the identifiable section are all cylindrical sections, the shape can be better maintained to be consistent, which is convenient for installation and use.

[0063] Specifically, the length of the recognizable segment can be any value within 2 - 8 mm. For example, the length of the recognizable segment is 3 - 7 mm. When the length is greater than 7 mm, the draw resistance is relatively large; when the length is less than 3 mm, the draw feeling is weak. Further, the preferred length of the recognizable segment is any value within 4 - 6 mm.

[0064] Exemplarily, the diameter of the resistance segment or the permeability segment is 3 - 10 mm. For example, the diameter is 4 - 9 mm. When the diameter is less than 4 mm, the draw resistance is relatively large; when the diameter is greater than 9 mm, the draw feeling is weak. Further, the preferred diameter is 5 - 8.5 mm. On the premise of ensuring performance, the volume can be further reduced to facilitate weight reduction.

[0065] In one embodiment, as Figure 2 shown, there is provided an aerosol generating device, including a controller, a heating device and an identifying device. The heating device and the identifying device are both connected to the controller. An accommodation cavity is formed in the aerosol generating device for accommodating the aerosol generating article of any of the above embodiments. Among them, the identifying device is used to identify the characteristic parameters of the recognizable segment and send them to the controller. The controller is used to control the heating device to work according to the characteristic parameters. The heating device is used to heat the aerosol generating article. The controller can determine the type of the aerosol generating article according to the identified characteristic parameters of the recognizable segment, and then heat the aerosol generating article specifically according to the type of the aerosol generating article, so that the flavor substances in the aerosol generating article are released more completely, improving the use taste, reducing the safety hazards caused by the mismatch between the aerosol generating device and the aerosol generating article, and the aerosol generating device can match corresponding heating methods for different types of aerosol generating articles, with high use convenience and also conducive to improving the quality of the aerosol and reliable operation.

[0066] The structure of the identifying device matches the type of the recognizable segment, and is used to identify the characteristic parameters of the recognizable segment and send them to the controller.

[0067] After the aerosol generating article is inserted into the accommodation cavity formed in the aerosol generating device, the controller can control the heating device to heat the aerosol generating article in the accommodation cavity, specifically heating the medium segment of the aerosol generating article.

[0068] In one embodiment, the controller is further configured to determine corresponding heating parameters according to characteristic parameters and control the heating device to operate according to the heating parameters. Specifically, the controller stores the correspondence between different types of aerosol-generating articles and heating methods. After determining the type of the aerosol-generating article, the heating method corresponding to the inserted aerosol-generating article is matched from the stored correspondence, and then the heating parameters are determined according to the matched heating method. Then, the heating device is controlled to heat the aerosol-generating article according to the heating parameters, so as to improve the quality of the generated aerosol and prevent problems such as device damage caused by the mismatch between the aerosol-generating article and the aerosol-generating device. In addition, different types of aerosol-generating articles can be adapted to the same aerosol-generating device, and there is no need to carry multiple aerosol-generating devices during use, which is convenient. It is understandable that the heating parameters can be a heating curve or a numerical value, etc., which are not limited herein.

[0069] In one embodiment, the recognizable segment is a resistance segment, and the recognition device is a resistance recognition device. The resistance recognition device can detect the resistivity of the recognizable segment and then send the resistivity to the controller, and the controller determines the type of the aerosol-generating article according to the resistivity. After the controller determines the type of the aerosol-generating article, the heating method corresponding to the type of the inserted aerosol-generating article is matched from the stored correspondence, and then the heating device is controlled to heat the aerosol-generating article according to the matched heating method.

[0070] Alternatively, the recognizable segment is a permeability segment, and the recognition device is an electromagnetic induction device. The electromagnetic induction device can detect the permeability of the recognizable segment and then send the permeability to the controller, and the controller determines the type of the aerosol-generating article according to the permeability. After the controller determines the type of the aerosol-generating article, the heating method corresponding to the type of the inserted aerosol-generating article is matched from the stored correspondence, and then the heating device is controlled to heat the aerosol-generating article according to the matched heating method.

[0071] In one embodiment, the controller is further configured to determine the number of uses according to the resistance of the resistance segment, and control the heating device to stop operating when the number of uses reaches a preset number-of-uses threshold.

[0072] Specifically, during the user's use, a low-pressure area is generated in the medium segment. After the user stops using, part of the aerosol flows back to the low-pressure area of the medium segment, and the flowing-back aerosol will adhere to the surface of the resistance segment. As the number of uses increases, the amount of the flowing-back aerosol adhering to the surface of the resistance segment also increases, which causes a change in the resistivity of the resistance segment. The resistance recognition device can detect the change in the resistivity of the resistance segment and send it to the controller, so that the controller can determine the number of uses according to the resistivity of the resistance segment. The controller compares the number of uses with the preset number-of-uses threshold, and when the number of uses reaches the preset number-of-uses threshold, controls the heating device to stop operating, so that the aerosol-generating article stops generating aerosol.

[0073] In this embodiment, the controller is further configured to determine the number of uses according to the resistance of the resistance section, and when the number of uses reaches a preset use number threshold, control the heating device to stop working, so as to realize the automatic control of the aerosol generation process.

[0074] In one embodiment, as Figure 2 shown, the aerosol generating device further includes a power-on recognition device. The power-on recognition device is connected to the controller and is used to detect whether an aerosol generating article is inserted into the accommodation cavity and send the detection result to the controller.

[0075] Specifically, the type of the power-on recognition device is not unique. For example, it can be an image acquisition device or a distance detection device, etc., as long as it can detect whether an aerosol generating article is inserted into the accommodation cavity of the aerosol generating device.

[0076] After the power-on recognition device sends the detection result to the controller, the controller can perform subsequent steps. For example, the controller can control the recognition device to start working, identify the characteristic parameters of the recognizable section of the aerosol generating article, so as to determine a suitable heating method, and then control the heating device to work accordingly.

[0077] Extendably, if the power-on recognition device detects that the aerosol generating article in the accommodation cavity is pulled out, the controller controls the heating device to stop working to avoid energy waste.

[0078] In one embodiment, an aerosol generating system is further provided, which includes an aerosol generating article according to any of the above embodiments and an aerosol generating device according to any of the above embodiments.

[0079] To better understand the above embodiments, the following will be explained in detail with a specific embodiment. In one embodiment, the aerosol generating system includes an aerosol generating device and an aerosol generating article.

[0080] The aerosol generating device and the aerosol generating article can cooperate through a resistance detection method. The aerosol generating device includes a power-on recognition device, a heating device, a recognition device, a battery and a controller, as Figure 2 shown. The recognition device is a resistance recognition device. The aerosol generating article includes: a filter section, a functional section, a medium section and a recognizable section. The recognizable section is at the bottom and is a resistance section. The medium section is connected to the resistance section and the functional section, and the filter section is at the top, as Figure 1 shown.

[0081] The aerosol-generating article is inserted into the aerosol-generating device. First, when the device is powered on, the insertion of the aerosol-generating article is detected by the identification device. Then, the resistance identification device detects the resistance section of the aerosol-generating article. The resistivity of the resistance sections made of different materials is different. The aerosol-generating device identifies the model of the inserted aerosol-generating article according to the value of the resistivity, and provides the corresponding heating rate and heating curve according to its model. After being heated, the aerosol-generating article generates hot aerosol. As the user sucks, the aerosol enters the user's mouth. During the user's sucking process, a low-pressure area is generated in the medium section. After the user stops sucking, part of the aerosol flows back to the low-pressure area of the medium section, and the flowing-back aerosol will adhere to the surface of the resistance section. As the number of puffs increases, the amount of the flowing-back aerosol adhering to the surface of the resistance section also increases, which causes a change in the resistivity of the resistance section. The resistance identification device collects the number of puffs of the aerosol-generating article by identifying the change in the resistivity of the resistance section until it detects that the number of puffs of the aerosol-generating article reaches the upper limit, and then the aerosol-generating device automatically cuts off the power and stops heating the aerosol-generating article.

[0082] In addition, the existence of the resistance section prevents the deformation and detachment of the medium section after heating, and also prevents the flowing-back aerosol from contaminating the aerosol-generating device, thereby achieving the purpose of easy cleaning.

[0083] Specifically, the material of the resistance section can be one or more conductive metals such as gold, silver, copper, iron, cobalt, nickel, aluminum, tungsten, platinum, lead, germanium, etc. and their corresponding alloys. The resistivity of the resistance section made of such materials is 1.4×10 -8 Ω·m - 5.1×10 -4 Ω·m.

[0084] Alternatively, the material of the resistance section can be one or more non-metallic materials such as graphite, graphene, carbon powder, silicon, etc. and their mixtures, and the resistivity is 0.7×10 -8 Ω·m - 6.4×10 2 Ω·m.

[0085] Alternatively, the material of the resistance section can be composed of one or more semiconductor materials such as TiO2, NiO, ZnO, ZnInS, CdS, C3N4, etc. The resistivity of the resistance section made of such materials is 1.0×10 -4 Ω·m - 2.0×10 2 Ω·m.

[0086] Alternatively, the material of the resistance segment can be prepared by uniformly mixing polymer materials such as polyethylene terephthalate, polylactic acid, polypropylene, acetate fiber, and epoxy resin with conductive metals such as gold, silver, copper, iron, cobalt, nickel, aluminum, tungsten, platinum, lead, germanium and their corresponding alloys, and then through extrusion, film pressing, hot pressing or injection molding. The resistivity of the resistance segment made of such materials is 7.5×10 -8 Ω·m - 9.3×10 -4 Ω·m.

[0087] Alternatively, the material of the resistance segment can be prepared by uniformly mixing polymer materials such as polyethylene terephthalate, polylactic acid, polypropylene, acetate fiber, and epoxy resin with semiconductor materials such as TiO2, NiO, ZnO, ZnInS, CdS, C3N4, and then through extrusion, film pressing, hot pressing or injection molding. The resistivity of the resistance segment made of such materials is 3.5×10 -4 Ω·m - 5.5×10 2 Ω·m.

[0088] Alternatively, the material of the resistance segment can be prepared by uniformly attaching conductive metals such as gold, silver, copper, iron, cobalt, nickel, aluminum, tungsten, platinum, lead, germanium and their corresponding alloys to the surfaces of polymer materials such as polyethylene terephthalate, polylactic acid, polypropylene, acetate fiber and epoxy resin. The resistivity of the resistance segment made of such materials is 4.5×10 -8 Ω·m - 6.8×10 -4 Ω·m.

The resistivity of the resistance segment made of such materials is 1.5×10 -4 Ω·m - 2.7×10 2 Ω·m.

[0090] For the above polyethylene terephthalate, polylactic acid, polypropylene, acetate fiber and epoxy resin, other thermoplastic or thermosetting polymer materials can also be selected. For the above conductive metals, other conductive metals can also be selected in addition to gold, silver, copper, iron, cobalt, nickel, aluminum, tungsten, platinum, lead, germanium and their alloys. For the above semiconductor materials, other semiconductor materials can also be selected in addition to TiO2, NiO, ZnO, ZnInS, CdS, C3N4.

[0091] The shape of the resistance section is a cylinder, and its diameter is 3 - 10 mm. For example, the diameter of the resistance section is 4 - 9 mm. When the diameter is less than 4 mm, the suction resistance is large; when the diameter is greater than 9 mm, the suction feeling is weak and it is inconvenient to use. Further, the diameter of the resistance section is 5 - 8.5 mm. The length of the resistance section is 2 - 8 mm. For example, the length of the resistance section is 3 - 7 mm. When the length is greater than 7 mm, the suction resistance is large; when the length is less than 3 mm, the suction feeling is weak and the use effect is poor. Further, the length of the resistance section is 4 - 6 mm.

[0092] Alternatively, the aerosol generating device and the aerosol generating article can also cooperate through electromagnetic detection. The aerosol generating device includes a heating device, an identification device, a battery and a controller. As Figure 2 shown, the identification device is an electromagnetic induction device. The aerosol generating article includes a filter section, a functional section, a medium section and an identifiable section. The identifiable section is a cleaning section. The cleaning section is at the bottom. The medium section is connected to the cleaning section and the functional section. The filter section is at the top. As Figure 1 shown.

[0093] After the aerosol generating article is inserted into the aerosol generating device, the magnetic permeabilities of the cleaning sections made of different materials are different. The aerosol generating device identifies the model of the inserted aerosol generating article according to the value of the magnetic permeability, and provides a corresponding heating rate and heating curve according to its model. After being heated, the aerosol generating article generates an aerosol at a higher temperature. This aerosol is generated by the medium section, enters the filter section after being cooled by the functional section, and can be used by the user after part of the miscellaneous gas is adsorbed by the filter section. The presence of the cleaning section prevents the medium section from deforming and falling off after heating, and also prevents the aerosol generating device from being polluted by the reflux aerosol, so as to achieve the purpose of easy cleaning.

[0094] Specifically, the material of the cleaning section can be ferromagnetic materials such as iron, cobalt, nickel and their corresponding alloys. The magnetic permeability of the cleaning section made of such materials is 20 - 1000×10 -6 H / m; the material of the cleaning section can be aluminum and its alloys. The magnetic permeability of the cleaning section made of such materials is 1 - 20 ×10 -6 H / m.

[0095] Alternatively, the material of the cleaning section can be graphite, and the magnetic permeability is 0.1 - 2×10 -6 H / m.

[0096] Alternatively, the cleaning section can be prepared by uniformly mixing polyethylene terephthalate with ferromagnetic materials such as iron, cobalt, nickel and their alloys and then by extrusion, film pressing, hot pressing or injection molding. The magnetic permeability of the cleaning section made of such materials is 100 - 600×10 -6 H / m.

[0097] Alternatively, the cleaning section can be prepared by uniformly mixing polylactic acid with ferromagnetic materials such as iron, cobalt, nickel, and their alloys, and then through extrusion, film pressing, hot pressing, or injection molding. The magnetic permeability of the cleaning section made of such materials is 200 - 900×10 -6 H / m.

[0098] Alternatively, the cleaning section can be prepared by uniformly mixing polypropylene with ferromagnetic materials such as iron, cobalt, nickel, and their alloys, and then through extrusion, film pressing, hot pressing, or injection molding. The magnetic permeability of the cleaning section made of such materials is 50 - 600×10 -6 H / m.

[0099] Alternatively, the cleaning section can be prepared by uniformly mixing cellulose acetate with ferromagnetic materials such as iron, cobalt, nickel, and their alloys, and then through extrusion, film pressing, hot pressing, or injection molding. The magnetic permeability of the cleaning section made of such materials is 100 - 700×10 -6 H / m.

[0100] Alternatively, the cleaning section can be prepared by uniformly mixing epoxy resin with ferromagnetic materials such as iron, cobalt, nickel, and their alloys, and then through extrusion, film pressing, hot pressing, or injection molding. The magnetic permeability of the cleaning section made of such materials is 10 - 500×10 -6 H / m.

[0101] Alternatively, the cleaning section can be prepared by uniformly attaching ferromagnetic materials such as iron, cobalt, nickel, and their alloys to the surfaces of polymer materials such as polyethylene terephthalate, polylactic acid, polypropylene, cellulose acetate, and epoxy resin. The magnetic permeability of the cleaning section made of such materials is 20 - 700×10 -6 H / m.

[0102] For the above polyethylene terephthalate, polylactic acid, polypropylene, cellulose acetate, and epoxy resin, other thermoplastic or thermosetting polymer materials can also be selected. For the above ferromagnetic materials, other ferromagnetic materials can also be selected in addition to iron, cobalt, nickel, and their alloys.

[0103] The cleaning section is in the shape of a cylinder, with a diameter of 3 - 10 mm. For example, the diameter of the cleaning section is 4 - 9 mm. When the diameter is less than 4 mm, the draw resistance is relatively large; when the diameter is greater than 9 mm, the suction feeling is weak. Further, the diameter of the cleaning section is 5 - 8.5 mm. The length of the cleaning section is 2 - 8 mm. For example, the length of the cleaning section is 3 - 7 mm. When the length is greater than 7 mm, the draw resistance is relatively large; when the length is less than 3 mm, the suction feeling is weak. Further, the length of the cleaning section is preferably 4 - 6 mm.

[0104] In order to verify the performance of the aerosol - generating article and the aerosol - generating device provided by this application, the inventor conducted the following experiments:

[0105] Experiment 1:

[0106] The aerosol-generating article A1 consists of a resistance section, a dielectric section, a functional section, and a filter section. The material of the resistance section is copper, with a resistivity of 1.7 ± 0.2×10 -8 Ω·m. It is in the shape of a cylinder, 5 mm in length and 7.3 mm in diameter. After inserting this aerosol-generating article into the aerosol-generating device, the appliance detects the insertion of the aerosol-generating article through the power-on recognition device. Then, the resistance recognition device identifies the product as A1 based on the resistivity and automatically adapts the corresponding heating curve. After fifteen puffs, the reflux aerosol adheres to the resistance section, and the resistance recognition device identifies the change in resistivity and thus shuts down the heating device.

[0107] Experiment 2:

[0108] The aerosol-generating article A2 consists of a resistance section, a dielectric section, a functional section, and a filter section. The polylactic acid is extruded into a cylindrical material, and a layer of metallic iron is coated on its surface. The resistivity is 2.0 ± 0.1×10 -7 Ω·m. It is in the shape of a cylinder, 5 mm in length and 7.4 mm in diameter. After inserting this aerosol-generating article into the aerosol-generating device, the appliance detects the insertion of the aerosol-generating article through the power-on recognition device. Then, the resistance recognition device identifies the product as A2 based on the resistivity and automatically adapts the corresponding heating curve. After seventeen puffs, the reflux aerosol adheres to the resistance section, and the resistance recognition device identifies the change in resistivity and thus shuts down the heating device.

[0109] Experiment 3:

[0110] The aerosol-generating article A3 consists of a dielectric section, a functional section, and a filter section, without a resistance section. When the aerosol-generating article A3 is inserted into the aerosol-generating device, the product type cannot be identified, and the heater cannot adapt the corresponding heating curve. Therefore, the suction experience of this aerosol-generating article is poor. In addition, since the number of puffs cannot be identified, after the aerosol in the aerosol-generating article is used up, the aerosol-generating device still does not automatically stop heating, which further reduces the use experience.

[0111] Comparing Experiments 1 to 3, it can be found that the aerosol-generating articles A1 - A2 containing a resistance section can be recognized by the aerosol-generating device for the product type and match the corresponding heating curve. Therefore, the product has a good suction experience. In addition, after use, the aerosol-generating device will automatically stop heating, which is beneficial to improving the user's experience. The aerosol-generating article A3 without a resistance section cannot be recognized by the aerosol-generating device. Therefore, the suction sensory experience is poor, and the aerosol-generating device cannot automatically stop heating after use, which also poses a safety hazard. Thus, it can be seen that the self-identifying aerosol system has a much better use experience than other aerosol products that cannot be recognized.

[0112] Experiment 4:

[0113] The aerosol generating article A4 consists of a cleaning section, a medium section, a functional section, and a filtering section. The material of the cleaning section is nickel-zinc alloy, and the magnetic permeability is (600±50)×10 -6 H / m. It is in the shape of a cylinder, with a length of 5 mm and a diameter of 7.3 mm. After inserting this aerosol generating article into the aerosol generating device, the appliance identifies the product as A4 through the electromagnetic induction device and automatically adapts to the corresponding heating curve. After taking out the aerosol generating article A4 after use, it is found that although the medium section is deformed, it does not fall off from the consumable, and the cavity of the aerosol generating device is clean without any stains remaining.

[0114] Experiment 5:

[0115] The aerosol generating article A5 consists of a cleaning section, a medium section, a functional section, and a filtering section. Acetate fiber and nickel are uniformly mixed in a mass ratio of 5:1 and then formed by membrane pressing. The magnetic permeability is (130±15)×10 -6 H / m. It is in the shape of a cylinder, with a length of 3 mm and a diameter of 7 mm. After inserting this aerosol generating article into the aerosol generating device, the appliance identifies the product as A5 through the electromagnetic induction device and automatically adapts to the corresponding heating curve. Similarly, after use, the medium section does not fall off and the cavity of the aerosol generating device is clean.

[0116] Experiment 6:

[0117] The aerosol generating article A6 consists of a cleaning section, a medium section, a functional section, and a filtering section. Epoxy resin and cobalt are uniformly mixed in a mass ratio of 2:1 and then formed by injection molding. The magnetic permeability is (60±10)×10 -6 H / m. It is in the shape of a cylinder, with a length of 5 mm and a diameter of 6 mm. After inserting this aerosol generating article into the aerosol generating device, the appliance identifies the product as A6 through the electromagnetic induction device and automatically adapts to the corresponding heating curve. Similarly, after use, the medium section does not fall off and the cavity of the aerosol generating device is clean.

[0118] It can be found from Comparative Experiments 3 to 6 that the aerosol generating articles A4 - A6 containing a cleaning section can be recognized by the aerosol generating device for the product type and match the corresponding heating curve, so the product suction experience is good. In addition, after use, the media of the aerosol generating articles A4 - A6 containing a cleaning section do not fall off, and the inside of the cavity of the aerosol generating device is clean. The aerosol generating article A3 without a cleaning section cannot be recognized by the aerosol generating device, so the suction sensory experience is poor, and the appliance is contaminated after use. Thus, it can be seen that the use experience of this easily cleanable self-inductive aerosol system is far better than that of other aerosol products that cannot be recognized.

[0119] The aerosol generation system provided by the present application can identify the type of aerosol generation article according to the resistivity of the resistance section or identify the type of aerosol generation article through the magnetic permeability of the cleaning section, and match the corresponding heating curve, thereby improving the quality of the generated aerosol. In addition, the presence of the cleaning section / resistance section prevents the medium section from deforming and falling off after heating, and also prevents the backflow aerosol from contaminating the aerosol generation device, thereby achieving the purpose of easy cleaning. After use, the aerosol production device will automatically stop heating, reducing potential safety hazards.
