Abstract
Description
Technical Field
[0001] This patent belongs to the field of electromagnetic induction heating technology, specifically relating to a heated cigarette for use in electromagnetic induction heating appliances. Background Technology
[0002] Heated cigarettes are tobacco products that generate an aerosol by heating an aerosol-generating matrix to a specific temperature for the user to inhale. The aerosol-generating matrix mainly consists of tobacco materials, smoke-generating agents (such as glycerin and propylene glycol), flavoring additives, and binders. These components work together to produce an aerosol containing nicotine and flavor. The typical smoke-generating temperature of heated cigarettes is 250℃~350℃. If the metal induction plate has poor heat conduction and the temperature is not reached, insufficient initial smoke release will occur. The latest heating method used in heated cigarette products is electromagnetic induction heating technology, such as IQOSILUMA, which uses a high-frequency electromagnetic field to generate eddy currents in the metal induction plate inside the cartridge, heating the tobacco. Although this method can improve heating efficiency and reduce physical contact, the longer heat transfer path still leads to insufficient initial smoke release.
[0003] E-cigarettes are another type of new tobacco product that releases smoke. The main components of the aerosol-generating matrix of this product include propylene glycol, glycerin, nicotine, and flavor additives. Its smoke-generating temperature is 100℃ to 300℃. It produces aerosols through evaporation and atomization. The content of propylene glycol and glycerin in e-cigarettes is about 30% to 50% and 50% to 70%, respectively. However, the smoke-generating temperature of heated cigarettes is generally 250℃ to 350℃, and the content of propylene glycol and glycerin is lower, about 5% to 15% and 5% to 20%, respectively. The sluggish heating function further aggravates the problem of insufficient smoke release.
[0004] In recent years, with the younger generation becoming the main consumer group and their increasing demand for personalization, young users are no longer satisfied with the single taste of traditional tobacco, but instead pursue a richer and more diverse flavor experience. This trend has driven the rapid development of new tobacco products that combine flavors and have a unique character. Heated cigarettes, as a representative of this new type of tobacco, push the personalized experience to the extreme with their multi-flavor adjustment function. Users can freely adjust the nicotine content, smoke volume, and flavor concentration according to their preferences to create a customized smoking experience. However, in actual production, the multi-flavor adjustment function is affected by the lag in the heating function, preventing the release of characteristic aromas and limiting the application of heated cigarettes.

[0006] To solve the above-mentioned technical problems, this patent adopts the following technical solution:

[0011] Furthermore, an aerosol matrix layer and an additive conditioning layer are arranged sequentially along the direction from the filter section to the plug.
[0012] Furthermore, the additive conditioning layer is a fragrance conditioning layer;
[0013] The additive conditioning layer is provided with a fragrance carrier, and the fragrance carrier material includes gel, porous material, microencapsulated fragrance carrier or fiber carrier;

[0022] Furthermore, the receptors can be sheet-like, cylindrical, or annular.
[0023] Furthermore, the sensor is made of an iron-based composite material, which includes ferromagnetic materials, stainless steel, or soft magnetic materials.
[0024] In this patent, the aerosol generation matrix segment contains an aerosol generation matrix.
[0025] Preferably, the aerosol generating matrix is a solid aerosol generating matrix. The aerosol generating matrix may include both solid and liquid components.
[0026] Preferably, the solid aerosol forming matrix may include one or more of the following: powder, granules, pellets, fragments, strips, bars, or sheets, and contains one or more of the following: herbaceous plant leaves, tobacco leaves, tobacco ribs, flat tobacco, and homogenized tobacco.
[0027] Alternatively, the solid aerosol forming matrix may contain tobacco volatile aromatic compounds or non-tobacco volatile aromatic compounds released when the solid aerosol forming matrix is heated. The solid aerosol forming matrix may also contain one or more capsules comprising, for example, additional tobacco volatile aromatic compounds or non-tobacco volatile aromatic compounds, and such capsules may melt during heating of the solid aerosol forming matrix.
[0028] Alternatively, the solid aerosol forming matrix can be disposed on or embedded in a heat-stabilized carrier. The carrier can be in the form of powder, granules, pellets, fragments, strips, bars, or sheets. The solid aerosol forming matrix can be arranged on the surface of the carrier, for example, in the form of sheets, foams, gels, or slurries. The solid aerosol forming matrix can be placed on the entire surface of the carrier, or alternatively, it can be patterned to provide uneven fragrance delivery during use.
[0029] Preferably, the aerosol-generating matrix includes nicotine. In some preferred embodiments, the aerosol-generating matrix includes tobacco.
[0030] In this patent, the sensor refers to a material that can convert electromagnetic energy into heat. When located in a fluctuating electromagnetic field, the eddy currents induced in the sensor cause it to heat up. When the elongated sensor is positioned in thermal contact with the aerosol-forming matrix, the aerosol-forming matrix is heated by the sensor. Furthermore, the sensor body, while performing temperature measurement, can also have the same function as the sensor, jointly achieving the heating of the aerosol-forming matrix.
[0031] Preferably, the aerosol generating article is designed to engage with an electrically operated aerosol generating device (i.e., an electromagnetic induction heater) including an induction source. The induction source generates a fluctuating electromagnetic field to heat a sensor located within the fluctuating electromagnetic field. In use, the aerosol generating article is engaged with the aerosol generating device such that the sensor is located within the fluctuating electromagnetic field generated by the induction source.
[0032] Preferably, the aerosol generating device is able to generate a fluctuating electromagnetic field between approximately 1 MHz and 30 MHz, for example, between 2 MHz and 10 MHz, or for example, between 5 MHz and 7 MHz, through the induction coil of the induction source.

The aerosol generating device can be substantially cylindrical in shape. The aerosol generating device can have a length between approximately 70 mm and approximately 120 mm.
[0037] This patent provides a heated cigarette for an electromagnetic induction heating device. By simultaneously arranging the sensor in the aerosol matrix layer and the additive conditioning layer, two areas are heated at the same time during heating, thereby increasing the heating rate. Furthermore, the additive conditioning layer can compensate for the problem of insufficient smoke release in the first puff and enrich the flavor.
[0038] The additive conditioning layer can serve as a high-smoke-generating agent conditioning layer. By sequentially setting the high-smoke-generating agent conditioning layer and the aerosol matrix layer in the near-mouth area of the heated cigarette, a higher smoke release can be achieved at lower temperatures, thereby effectively compensating for the problem of insufficient smoke in the first puff.
[0039] The additive adjustment layer can also serve as a flavor adjustment layer for replaceable modules. Designing multi-layered heated cigarettes as a modular, replaceable structure not only enhances the product's flexibility and playability but also allows consumers to freely adjust and change the overall flavor of the heated cigarette according to their personal preferences, further enhancing the personalization and enjoyment of the user experience. This design not only solves technical pain points but also provides consumers with more space for exploration and enjoyment. Attached Figure Description

[0062] To facilitate the explanation of how this patented heated cigarette works, as follows: Figure 5 As shown, the electromagnetic induction heating device 2 is arranged to receive the aerosol generating matrix section so that the aerosol generating matrix in the heated cigarette 1 generates aerosol. The electromagnetic induction heating device 2 and the heated cigarette 1 inserted therein constitute an aerosol generating system. The heated cigarette 1 can be any of the following embodiments. The electromagnetic induction heating device 2 includes a housing, a power supply and control assembly 22, a heating chamber 21 for receiving at least a portion of the heated cigarette 1, and an electromagnetic wave emitting induction coil 23 as the induction source. When the heated cigarette 1 is inserted into the electromagnetic induction heating device 2, the power supply and control assembly 22 activates the heating mode. Electrical energy from the power supply is supplied to the induction coil 23 in an alternating current manner and to the electromagnetic induction body 15 in the form of electromagnetic waves. After receiving the energy, the electromagnetic induction body 15 can heat the aerosol generating matrix section.
[0063] Example 1
[0064] like Figure 1 As shown, this embodiment provides a heated cigarette 1 for an electromagnetic induction heating device. The heated cigarette 1 includes an aerosol generating matrix section, a filter section, and a sensor. The sensor is used to inductively heat the aerosol generating matrix section under the influence of an alternating electromagnetic field generated by an induction source to form an aerosol for the user to inhale. The aerosol generating matrix section includes an aerosol matrix layer 14 and an additive conditioning layer 13, which are arranged in an array. The sensor is arranged along the axial direction of the aerosol generating matrix section in the aerosol matrix layer 14 and the additive conditioning layer 13. The sensor is an electromagnetic induction element 15, and both the aerosol matrix layer 14 and the additive conditioning layer 13 may contain an aerosol generating matrix for forming an aerosol.
[0065] Specifically, the additive conditioning layer 13 and the aerosol matrix layer 14 are arranged sequentially along the direction from the filter section to the plug 16. The filter section of the heated cigarette 1 includes a filter tip section 11 and a cooling section 12. The heated cigarette 1 is arranged axially from the near end to the far end as the filter tip section 11, the cooling section 12, the additive conditioning layer 13, the aerosol matrix layer 14 and the plug 16. The electromagnetic induction element 15 is located at the center of the additive conditioning layer 13 and the aerosol matrix layer 14 to improve the heating uniformity.
[0066] More specifically, the additive conditioning layer 13 is a high-smoke-generating agent conditioning layer. Preferably, the aerosol matrix layer 14 also contains a smoke-generating agent, and the smoke-generating agent content in the additive conditioning layer 13 is higher than that in the aerosol matrix layer 14. The additive conditioning layer 13 is structurally closer to the electromagnetic induction element 15 or the filter section 11 than the aerosol matrix layer 14, which can further achieve the purpose of pre-sensing temperature and generating smoke. The addition ratio of the additive conditioning layer 13 to the aerosol matrix layer 14 should be less than 1, that is, the axial length of the additive conditioning layer 13 is greater than the axial length of the aerosol matrix layer 14, so that it plays a role in the early stage of the entire inhalation process without affecting the overall smoke balance.
[0067] Specifically, the additive conditioning layer 13 and the aerosol matrix layer 14 can be composed of tobacco materials, smoke-generating agents (such as glycerin, propylene glycol), flavoring additives, etc., the difference being that the smoke-generating agent content in the additive conditioning layer 13 should be higher than that in the aerosol matrix layer 14. Additionally, the additive conditioning layer 13 can be in the form of a gel, liquid, membrane, or porous contents, and its composition includes smoke-generating agents, nicotine, flavoring additives, etc.
[0068] Specifically, the additive conditioning layer 13 is a replaceable module, with a channel in the middle to accommodate the electromagnetic induction element 15. More specifically, one or more electromagnetic induction elements 15 are respectively disposed in the aerosol matrix layer 14 and the additive conditioning layer. More specifically, one or more electromagnetic induction elements 15 can be disposed in the aerosol matrix layer 14 and the additive conditioning layer 13, and different sensors can be disposed for different layers to achieve non-uniform temperature heating. At least one electromagnetic induction element 15 is simultaneously disposed in both the aerosol matrix layer 14 and the additive conditioning layer 13 through the channel.
[0069] Specifically, the heated cigarette 1 is integrally formed by cigarette paper 17. In order to ensure that the cigarette paper 17 is not damaged and to protect each cigarette layer when the module is replaced, the cigarette paper 17 should have a certain strength, preferably with the following values: basis weight 40-60 g / m2; longitudinal tensile strength ≥3.0 kN / m, transverse tensile strength ≥1.5 kN / m; thickness 50-80 μm; and its constituent fiber components can be flax fiber, wood pulp fiber or mixed fiber.
[0070] More specifically, the end cap 16 should have a certain frictional force on the inner wall of the cigarette paper 17 in the circumferential direction, so as not to fall vertically due to the weight of the end cap 16. The optimal value of its parameters varies depending on the type and specification of the end cap 16 in actual production. Alternatively, the cigarette paper 17 can be set as a bib structure, which is made by splicing together ordinary cigarette paper with good flexibility and folding.
[0071] Specifically, the electromagnetic induction element 15 can be sheet-like, cylindrical, annular, or other shapes that can be accommodated within the heated cigarette 1. Its material is generally ferromagnetic, stainless steel, soft magnetic, or other iron-based composite materials, and can be inductively heated to the required temperature (generally 350°C).
[0072] In this embodiment, the high smoke-generating agent conditioning layer, by sequentially layering the high smoke-generating agent conditioning layer and the aerosol matrix layer in the near-mouth area of the heated cigarette, can achieve a higher smoke release at a lower temperature, thereby effectively compensating for the problem of insufficient smoke in the first puff.
[0073] Example 2
[0074] like Figure 2-4 As shown, this embodiment provides a heated cigarette 1 for an electromagnetic induction heating device. The heated cigarette 1 includes an aerosol generating matrix section, a filter section, and a sensor. The sensor is used to inductively heat the aerosol generating matrix section under the influence of an alternating electromagnetic field generated by an induction source to form an aerosol for the user to inhale. The aerosol generating matrix section includes an aerosol matrix layer 14 and an additive conditioning layer 13, which are arranged in an array. The sensor is arranged along the axial direction of the aerosol generating matrix section in the aerosol matrix layer 14 and the additive conditioning layer 13. The sensor is an electromagnetic induction element 15. The filter section of the heated cigarette 1 includes a filter tip section 11 and a cooling section 12. Both the aerosol matrix layer 14 and the additive conditioning layer 13 may contain an aerosol generating matrix for forming an aerosol.
[0075] Specifically, an aerosol matrix layer 14 and an additive conditioning layer 13 are arranged sequentially along the direction from the filter section to the plug 16. The additive conditioning layer 13 is a fragrance conditioning layer, which facilitates the replacement of fragrance conditioning layers with different fragrance substances and fragrance carriers. This layer can be made of gel, porous material, or other fragrance carrier gel with high adsorption capacity to stably store fragrance substances. Among them, porous materials can be made of porous ceramics or activated carbon. Other fragrance carriers, such as microencapsulated fragrances or fiber carriers, can maintain the persistence and controlled release of fragrance. Fragrance substances can be set as fragrances, cooling agents, nicotine salts, etc., preferably substances with a boiling point lower than that of the aerosol matrix layer 14.
[0076] When the electromagnetic induction body 15 heats up, the additive conditioning layer 13 will release the aroma substances first. During the consumer's inhalation, these aroma substances will pass through the aerosol matrix layer 14, which not only enhances the aroma but also preheats the smoke-generating layer, thereby improving the overall layering and smoothness of the inhalation experience.
[0077] Preferably, the aerosol matrix layer 14 also contains a smoke-generating agent, and the smoke-generating agent content in the additive conditioning layer 13 is higher than that in the aerosol matrix layer 14. The additive conditioning layer 13 has a structure more similar to that of the electromagnetic induction element 15 or the filter section 11 than the aerosol matrix layer 14, which can further achieve the purpose of pre-sensing temperature and generating smoke. The addition ratio of the additive conditioning layer 13 to the aerosol matrix layer 14 should be less than 1, that is, the axial length of the additive conditioning layer 13 is greater than the axial length of the aerosol matrix layer 14, so that it plays a role in the early stage of the entire inhalation process without affecting the overall balance of smoke volume.
[0078] Specifically, the additive conditioning layer 13 is a replaceable module, with a channel 18 in the middle to accommodate the electromagnetic induction sensor 15. Users can choose modules with different fragrances or functions according to their personal preferences, achieving diversified and personalized odor absorption. More specifically, one or more electromagnetic induction sensors 15 can be respectively set in the aerosol matrix layer 14 and the additive conditioning layer 13, and different sensors can be set for different layers to achieve non-uniform temperature heating. At least one electromagnetic induction sensor 15 is simultaneously set in both the aerosol matrix layer 14 and the additive conditioning layer 13 through the channel 18.
[0079] Specifically, the heated cigarette 1 is integrally formed by cigarette paper 17. In order to ensure that the cigarette paper 17 is not damaged and to protect each cigarette layer when the module is replaced, the cigarette paper 17 should have a certain strength, preferably with the following values: basis weight 40-60 g / m2; longitudinal tensile strength ≥3.0 kN / m, transverse tensile strength ≥1.5 kN / m; thickness 50-80 μm; and its constituent fiber components can be flax fiber, wood pulp fiber or mixed fiber.
[0080] More specifically, the end cap 16 should have a certain frictional force on the inner wall of the cigarette paper 17 in the circumferential direction, so as not to fall vertically due to the weight of the end cap 16. The optimal value of its parameters varies depending on the type and specification of the end cap 16 in actual production. Alternatively, the cigarette paper 17 can be set as a bib structure, which is made by splicing together ordinary cigarette paper with good flexibility and folding.
[0081] Specifically, the electromagnetic induction element 15 can be sheet-like, cylindrical, annular, or other shapes that can be accommodated within the heated cigarette 1. Its material is generally ferromagnetic, stainless steel, soft magnetic, or other iron-based composite materials, and can be inductively heated to the required temperature (generally 350°C).
[0082] In this embodiment, the flavor adjustment layer is designed as a modular, replaceable structure for the multi-layer heated cigarette. This not only enhances the product's flexibility and playability but also allows consumers to freely adjust and change the overall flavor of the heated cigarette according to their personal preferences, further enhancing the personalization and enjoyment of the user experience. This design not only solves technical pain points but also provides consumers with more space for exploration and enjoyment.
