Description

Technical Field

[0001] This patent belongs to the technical field of electromagnetic induction heating, and specifically relates to a heated cigarette for an electromagnetic induction heating appliance. Background Art

[0002] A heated cigarette is a tobacco product that generates an aerosol by heating an aerosol-forming substrate to a specific temperature for the user to inhale. The main components of the aerosol-forming substrate include tobacco materials, fuming agents (such as glycerin and propylene glycol), flavor additives, and binders. Under the combined action of these components, an aerosol containing nicotine and flavor is produced. Generally, the fuming temperature of a heated cigarette is 250°C to 350°C. When the metal sensor has a thermal conduction lag and the temperature does not reach this temperature, it will cause insufficient release of the first puff of smoke. The latest heating method applied to heated cigarette products is electromagnetic induction heating technology, such as IQOS ILUMA, which uses a high-frequency electromagnetic field to cause eddy currents in the metal sensor inside the cartridge to heat the tobacco. Although this solution can improve the heating efficiency and reduce physical contact, due to the long heat transfer path, there is a problem of insufficient release of the first puff of smoke. The main reasons include: 1. Thermal conduction delay: Induction heating first acts on the metal sheet and then heats the tobacco by conduction, resulting in a time lag. 2. Low initial temperature of the tobacco: Due to limited preheating time, the release of the first puff of smoke is insufficient, affecting the user experience. 3. Power control strategy: The electromagnetic induction system usually adopts a progressive temperature rise curve, resulting in a slow initial heating rate. Therefore, there is a need to provide a heated cigarette to solve the problem of insufficient release of the first puff of smoke. Summary of the Invention

[0015] Furthermore, the electromagnetic induction intensifying matrix layer can be set in the form of a gel, liquid, film, or porous content.

[0016] Furthermore, the electromagnetic induction intensifying matrix layer includes a smoke agent, tobacco material, and flavor additive.

[0020] In this patent, the aerosol - generating matrix section contains an aerosol - generating matrix.

[0021] Preferably, the aerosol - generating matrix is a solid aerosol - forming matrix. The aerosol - generating matrix can include both solid and liquid components simultaneously.

[0024] Optionally, the solid aerosol-forming substrate may be disposed on or embedded in a heat-stable carrier. The carrier may be in the form of powders, granules, pellets, fragments, strips, rods or sheets. The solid aerosol-forming substrate may be arranged on the surface of the carrier in the form of, for example, a sheet, foam, gel or slurry.

[0025] Preferably, the aerosol-generating substrate comprises nicotine. In some preferred embodiments, the aerosol-generating substrate comprises tobacco.

[0026] In this patent, a susceptor refers to a material that can convert electromagnetic energy into heat. When located in a fluctuating electromagnetic field, eddy currents induced in the susceptor cause heating of the susceptor. When an elongated susceptor is positioned in thermal contact with the aerosol-forming substrate, the aerosol-forming substrate is heated by the susceptor. Further, the receptor can have the same function as the susceptor while performing temperature measurement, and together they can achieve heating of the aerosol-forming substrate.

[0027] Preferably, the aerosol-generating article is designed to engage with an electrically-operated aerosol-generating device (i.e., an electromagnetic induction heating appliance) comprising an induction source. The induction source generates a fluctuating electromagnetic field so as to heat a susceptor located within the fluctuating electromagnetic field. In use, the aerosol-generating article is engaged with the aerosol-generating device such that the susceptor is located within the fluctuating electromagnetic field generated by the induction source.

[0028] Preferably, the aerosol-generating device can generate a fluctuating electromagnetic field between about 1 MHz and 30 MHz, such as between 2 MHz and 10 MHz, such as between 5 MHz and 7 MHz, through the induction coil of the induction source.

The shape of the aerosol generating device can basically be cylindrical. The aerosol generating device can have a length between approximately 70 mm and approximately 120 mm.

[0033] The present invention provides a heated cigarette for an electromagnetic induction heating appliance. By setting the positions of the electromagnetic induction surrounding matrix layer and the electromagnetic induction strong emission area, when heating, the amount of smoke generated in the electromagnetic induction strong emission area is greater than that in the electromagnetic induction surrounding matrix layer, so as to meet the requirement of achieving a higher smoke release amount at a lower heating temperature, thereby making up for the problem of insufficient smoke release amount in the first puff of the existing heated cigarette.

[0034] At the same time, this patent also uses a receptor with a special shape. Due to the skin effect, the electric field will be concentrated at the tip of the receptor, thus generating more heat, making it easier for the electromagnetic induction strong emission matrix layer embedded in the concave part to generate aerosol, and it is also easier to implement in the composite process. Due to the special shape with multiple upward protrusions or downward depressions, the heating rate of the heated cigarette is relatively fast, and the initial temperature of the tobacco can be quickly increased. The influence of heat conduction delay is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] For the convenience of explaining the working mode of the heated cigarette of this patent, as Figure 13 shown, the electromagnetic induction heating appliance 2 is arranged to receive an aerosol-generating substrate section so as to generate aerosol from the aerosol-generating substrate in the heated cigarette 1. The electromagnetic induction heating appliance 2 and the heated cigarette 1 inserted therein constitute an aerosol-generating system.

The electromagnetic induction heating appliance 2 includes a housing, a power supply and control assembly 22, a heating chamber 21 for receiving at least a part of the heated cigarette 1, and an electromagnetic wave-emitting induction coil 23 serving as an induction source.

After receiving the energy, the electromagnetic induction body 15 can heat the aerosol-generating substrate section.

[0064] This patent provides a heated cigarette for an electromagnetic induction heating appliance. The heated cigarette includes an aerosol-generating substrate section and a filter section. The aerosol-generating substrate section includes an electromagnetic induction surrounding substrate layer and an electromagnetic induction strong emission area. The electromagnetic induction surrounding substrate layer wraps the electromagnetic induction strong emission area. The electromagnetic induction strong emission area includes a receptor and an electromagnetic induction strong emission substrate layer. The receptor is used to inductively heat the electromagnetic induction strong emission substrate layer and the electromagnetic induction surrounding substrate layer under the influence of an alternating electromagnetic field generated by an induction source. Among them, the filter section includes a filter tip section and a cooling section. The electromagnetic induction strong emission substrate layer is closer to the receptor or the filter section than the electromagnetic induction surrounding substrate layer. The receptor is an electromagnetic induction body to achieve the purpose of pre-sensing temperature and generating smoke.

[0065] Specifically, the cooling section has a low suction resistance. That is, preferably, the cooling section provides a low resistance to air passing through the heated cigarette. Preferably, the cooling section basically does not affect the suction resistance of the heated cigarette.

[0066] Specifically, the electromagnetic induction intensifying matrix layer is coated around the receptor.

[0067] Preferably, the receptor has a special shape. At this time, the electromagnetic inductor is used as a special body. The material of the electromagnetic inductor is generally a ferromagnetic material, stainless steel, soft magnetic material or other iron-based composite materials, and materials that can be inductively heated to the required temperature (generally 350 °C) are acceptable.

[0068] Specifically, at least part of the receptor has a shape with an upward bulge or a downward depression.

[0069] Exemplarily, the receptor is a plurality of continuous inverted triangle structures.

[0070] Exemplarily, the receptor is a plurality of cone structures arranged side by side.

[0071] Exemplarily, the receptor is a plurality of downwardly concave hemispherical structures.

[0072] In addition, the receptor is in the shape of a sheet, a cylinder, a ring or other shapes that can be accommodated in a heated cigarette, and the electromagnetic induction intensifying matrix layer is filled inside the receptor.

[0073] Specifically, a plug is provided at one end of the electromagnetic induction surrounding matrix layer away from the filter section.

[0074] Preferably, the axial length of the electromagnetic inductor is at least 0.7 - 0.75, 0.75 - 0.80, 0.80 - 0.85, 0.85 - 0.90, 0.90 - 0.95 or 0.95 - 1.00 times the axial length of the electromagnetic induction intensifying matrix layer.

[0075] Specifically, the added weight ratio of the electromagnetic induction intensifying matrix layer to the electromagnetic induction surrounding matrix layer is less than 1.

[0076] Specifically, the content of the smoke generator in the electromagnetic induction intensifying matrix layer is higher than that in the electromagnetic induction surrounding matrix layer.

[0077] Specifically, the electromagnetic induction intensifying matrix layer can be set in the form of a gel, a liquid, a film or a porous content.

[0078] Specifically, the electromagnetic induction intensifying matrix layer includes a smoke generator, a tobacco material and a flavor additive.

[0079] Specifically, the smoke generator includes glycerol and propylene glycol.

[0080] Specifically, the glycerol content is 5% - 7%, 7% - 9%, 9% - 11%, 11% - 13% or 13% - 15% of the mass of the aerosol generating matrix section.

[0081] Specifically, the content of propylene glycol is 5% - 7%, 7% - 9%, 9% - 11%, 11% - 13%, 13% - 15%, 15% - 17% or 17% - 20% of the mass of the aerosol - generating substrate section.

[0082] For the e - cigarette category among new - type tobacco products that release smoke, the main components of the aerosol - generating substrate in this category include propylene glycol, glycerol, nicotine, flavor additives, etc. Its smoking temperature is 100°C - 300°C, and aerosol is generated through evaporation and atomization. The content of propylene glycol and glycerol in e - cigarettes is approximately 30% - 50% and 50% - 70% respectively; while the content of propylene glycol and glycerol in this patent is relatively low, approximately 5% - 15% and 5% - 20% respectively. An electromagnetic induction - surrounded matrix layer and an electromagnetic induction - enhanced emission area are arranged in a partitioned manner in the area near the induction heating element or the near - mouth end, so as to quickly heat up and reach a higher smoke release amount at a lower temperature, thereby compensating for the problem of insufficient first - puff smoke. On the other hand, when the aerosol - generating substrate is arranged in a partitioned manner, it can have different flavors to enrich the taste of the heated cigarette. To further illustrate the specific structure of this patent, the structures of heated cigarettes in Examples 1 - 4 are given below.

[0083] Example 1

[0084] As Figures 1 - 3 shown, the heated cigarette 1 is axially arranged from the proximal end to the distal end in sequence as a filter section 11, a cooling section 12, an electromagnetic induction - surrounded matrix layer 13 and an electromagnetic induction - enhanced emission matrix layer 14, and a plug 16. Further, an electromagnetic inductor 15 is provided inside the electromagnetic induction - enhanced emission matrix layer 14.

[0085] Specifically, the electromagnetic inductor 15 is in a sheet shape, and the electromagnetic induction - enhanced emission matrix layer 14 is coated around the electromagnetic inductor 15. When rolling the heated cigarette 1, only the process of combining the two needs to be added, without changing other rolling, joining, and packaging processes.

[0086] Specifically, a plug 16 is arranged at one end of the electromagnetic induction - surrounded matrix layer 13 away from the filter section. Among them, the plug 16 in this patent serves both as a seal for the filter section 11 to prevent the aerosol - generating substrate from getting damp and provides a supporting force for the aerosol - generating substrate section of this patent. Due to the setting that the electromagnetic induction - surrounded matrix layer 13 wraps the electromagnetic induction - enhanced emission area, the receptor in the electromagnetic induction - enhanced emission area is easily compressed and deformed, and the plug 16 can further provide a protective supporting force for the receptor.

[0087] Specifically, to compensate for the insufficient release of the first puff of smoke, the addition weight ratio of the electromagnetic induction strong release matrix layer 14 to the electromagnetic induction surrounding matrix layer 13 is less than 1, so that it plays a role in the front stage of the whole suction process without affecting the balance of the overall smoke volume. When set like this to increase the flavor of the heated cigarette 1, the ratio of the two can be freely adjusted as needed. When the purpose is to release smoke in advance at a lower temperature, the electromagnetic induction strong release matrix layer 14 and the electromagnetic induction surrounding matrix layer 13 can be composed of tobacco materials, smoke agents (such as glycerol, propylene glycol), flavor additives, etc. The tobacco material is nicotine, and the content of the smoke agent in the electromagnetic induction strong release matrix layer 14 is higher than that in the electromagnetic induction surrounding matrix layer 13. When the purpose is to add flavor and enrich the taste, the difference between the electromagnetic induction strong release matrix layer 14 and the electromagnetic induction surrounding matrix layer 13 can be the difference in flavor additives.

[0088] Specifically, the electromagnetic induction strong release matrix layer 14 can be set in the form of a gel, liquid, film or porous content.

[0089] Specifically, the electromagnetic induction strong release matrix layer 14 includes a smoke agent, a tobacco material and a flavor additive.

[0090] Specifically, the smoke agent includes glycerol and propylene glycol.

[0091] Specifically, the content of glycerol is 5% - 7%, 7% - 9%, 9% - 11%, 11% - 13% or 13% - 15% of the mass of the aerosol generation matrix section.

[0092] Specifically, the content of propylene glycol is 5% - 7%, 7% - 9%, 9% - 11%, 11% - 13%, 13% - 15%, 15% - 17% or 17% - 20% of the mass of the aerosol generation matrix section.

[0093] The heated cigarette of this embodiment has passed the suction test, and its smoke volume is higher than that of conventional heated cigarettes, especially the smoke volume of the first puff is increased.

[0094] Example 2

[0095] As Figures 4 - 5 shown, the heated cigarette 1 is axially arranged in sequence from the proximal end to the distal end as a filter section 11, a cooling section 12, an electromagnetic induction surrounding matrix layer 13 and an electromagnetic induction strong release matrix layer 14, a plug 16, and further provided with an electromagnetic inductor 15 located in the electromagnetic induction strong release matrix layer 14.

[0096] Specifically, the electromagnetic inductor 15 is in the shape of a sheet, the electromagnetic induction strong release matrix layer 14 is coated around the electromagnetic inductor 15, and the electromagnetic induction strong release matrix layer 14 and the electromagnetic induction surrounding matrix layer 13 are circularly combined to form a uniform multi-layer aerosol generation matrix.

[0097] Specifically, a plug 16 is provided at one end of the electromagnetic induction surrounding matrix layer 13 away from the filtering section. Among them, the plug 16 in this patent serves both as a seal for the filter tip section 11 to prevent the aerosol generation matrix from getting damp, and provides a supporting force for the aerosol generation matrix section of this patent. Due to the setting that the electromagnetic induction surrounding matrix layer 13 wraps the electromagnetic induction strong emission area, the receptors in the electromagnetic induction strong emission area are prone to being compressed and deformed, and the plug 16 can further provide a protective supporting force for the receptors.

[0098] Specifically, to compensate for the insufficient release of the first puff of smoke, the added weight ratio of the electromagnetic induction strong emission matrix layer 14 to the electromagnetic induction surrounding matrix layer 13 is less than 1, so that it plays a role in the front stage of the whole smoking process without affecting the balance of the overall smoke volume. When set like this to increase the flavor of the heated cigarette 1, the ratio of the two can be freely adjusted according to needs. When the purpose is to release smoke in advance at a lower temperature, the electromagnetic induction strong emission matrix layer 14 and the electromagnetic induction surrounding matrix layer 13 can be composed of tobacco materials, smoke generators (such as glycerol, propylene glycol), flavor additives, etc. The tobacco material is nicotine, and the content of the smoke generator in the electromagnetic induction strong emission matrix layer 14 is higher than that in the electromagnetic induction surrounding matrix layer 13. When the purpose is to add flavor and enrich the taste, the difference between the electromagnetic induction strong emission matrix layer 14 and the electromagnetic induction surrounding matrix layer 13 can be the difference in flavor additives.

[0099] Specifically, the electromagnetic induction strong emission matrix layer 14 can be set in the form of a gel, liquid, film or porous content.

[0100] Specifically, the electromagnetic induction strong emission matrix layer 14 includes a smoke generator, a tobacco material and a flavor additive.

[0101] Specifically, the smoke generator includes glycerol and propylene glycol.

[0102] Specifically, the content of glycerol is 5% - 7%, 7% - 9%, 9% - 11%, 11% - 13% or 13% - 15% of the mass of the aerosol generation matrix section.

[0103] Specifically, the content of propylene glycol is 5% - 7%, 7% - 9%, 9% - 11%, 11% - 13%, 13% - 15%, 15% - 17% or 17% - 20% of the mass of the aerosol generation matrix section.

[0104] The heated cigarette of this embodiment has passed the smoking test, and its smoke volume is higher than that of conventional heated cigarettes, especially the smoke volume of the first puff is increased.

[0105] Example 3

[0106] Such as Figures 6 - 7As shown, the heated tobacco product 1 is axially arranged from proximal to distal in sequence as a filter segment 11, a cooling segment 12, an electromagnetic induction surrounding matrix layer 13, an electromagnetic induction strong emission matrix layer 14, and a plug 16.

[0107] Specifically, the electromagnetic inductor 15 is in the shape of a sheet, a cylinder, or a ring, preferably a ring. The electromagnetic induction strong emission matrix layer 14 is filled inside the ring-shaped electromagnetic inductor 15. When breathable membranes are provided at both ends of the electromagnetic inductor 15, the electromagnetic induction strong emission matrix layer 14 can be set in the form of a liquid, a gel, etc.

[0108] Specifically, a plug 16 is provided at one end of the electromagnetic induction surrounding matrix layer 13 away from the filter segment. Among them, the plug 16 in this patent serves both as a seal for the filter segment 11 to prevent the aerosol-forming matrix from getting damp and provides a supporting force for the aerosol-forming matrix segment of this patent. Due to the setting that the electromagnetic induction surrounding matrix layer 13 wraps the electromagnetic induction strong emission area, the sensors in the electromagnetic induction strong emission area are prone to being compressed and deformed, and the plug 16 can further provide a protective supporting force for the sensors.

[0109] Specifically, to compensate for the insufficient release of the first puff of smoke, the added weight ratio of the electromagnetic induction strong emission matrix layer 14 to the electromagnetic induction surrounding matrix layer 13 is less than 1, so that it plays a role in the front stage of the whole suction process without affecting the balance of the overall smoke volume. When set in this way to increase the flavor of the heated tobacco product 1, the ratio of the two can be freely adjusted according to needs. When the purpose is to release smoke in advance at a lower temperature, the electromagnetic induction strong emission matrix layer 14 and the electromagnetic induction surrounding matrix layer 13 can be composed of tobacco materials, smoke agents (such as glycerol, propylene glycol), flavor additives, etc. The tobacco material is nicotine, and the content of the smoke agent in the electromagnetic induction strong emission matrix layer 14 is higher than that in the electromagnetic induction surrounding matrix layer 13. When the purpose is to add flavor and enrich the taste, the difference between the electromagnetic induction strong emission matrix layer 14 and the electromagnetic induction surrounding matrix layer 13 can be the difference in flavor additives.

[0110] Specifically, the electromagnetic induction strong emission matrix layer 14 can be set in the form of a gel, a liquid, a film, or a porous content.

[0111] Specifically, the electromagnetic induction strong emission matrix layer 14 includes a smoke agent, a tobacco material, and a flavor additive.

[0112] Specifically, the smoke agent includes glycerol and propylene glycol.

[0113] Specifically, the content of glycerol is 5% - 7%, 7% - 9%, 9% - 11%, 11% - 13%, or 13% - 15% of the mass of the aerosol-forming matrix segment.

[0114] Specifically, the content of propylene glycol is 5% - 7%, 7% - 9%, 9% - 11%, 11% - 13%, 13% - 15%, 15% - 17% or 17% - 20% of the mass of the aerosol - generating substrate section.

[0115] The heated cigarette of this embodiment has undergone a puffing test, and its smoke volume is higher than that of conventional heated cigarettes, especially the smoke volume of the first puff is increased.

[0116] Example 4

[0117] In this embodiment, the purpose is to further illustrate the electromagnetic induction surrounding matrix layer and the electromagnetic induction strong - emission area of the heated cigarette. The rest of the components can adopt the solutions in Examples 1 - 3. The electromagnetic induction surrounding matrix layer 13 wraps the electromagnetic induction strong - emission area, the electromagnetic induction strong - emission matrix layer 14 is coated around the electromagnetic induction body 15, the electromagnetic induction body 15 has an irregular shape, and at least part of the electromagnetic induction body 15 has a shape with an upward bulge or a downward depression.

[0118] As an example, as Figure 8 shown in the first structure of the electromagnetic induction strong - emission area, the electromagnetic induction body 15 is composed of multiple continuous inverted - triangle structures. Taking the M - type inductor as an example, the electromagnetic induction strong - emission matrix layer 14 can be in the form of a gel, solid, etc. and be embedded in the electromagnetic induction body 15. In the electromagnetic induction magnetic field, due to the skin effect, the electric field at the tip of the electromagnetic induction body 15 will be concentrated, generating more heat, making the electromagnetic induction strong - emission matrix layer 14 embedded in the depression more likely to generate aerosol, and it is easier to solve the problem of insufficient release of the smoke volume of the first - puff flue gas in the composite process. The heated cigarette of this example has undergone a puffing test, and its smoke volume is higher than that of conventional heated cigarettes, especially the smoke volume of the first puff is increased, the puffing taste is good, and the characteristic flavor is obvious.

[0119] As another example, as Figures 9 - 10 shown in the second electromagnetic induction strong - emission area, the electromagnetic induction body 15 is composed of multiple cone structures arranged side by side, and the electromagnetic induction strong - emission matrix layer 14 is laid in a layered manner above the cone structure. Due to the skin effect, the electric field at the tip of the electromagnetic induction body 15 will be concentrated, generating more heat, making the electromagnetic induction strong - emission matrix layer 14 laid in a layered manner more likely to generate aerosol, and it is easier to solve the problem of insufficient release of the smoke volume of the first - puff flue gas in the composite process. The heated cigarette of this example has undergone a puffing test, and its smoke volume is higher than that of conventional heated cigarettes, especially the smoke volume of the first puff is increased, the puffing taste is good, and the characteristic flavor is obvious.

[0120] As another example, as Figures 11 - 12Shown is the third strong electromagnetic induction area. The electromagnetic inductor 15 is a structure of multiple downwardly concave hemispheres. The strong electromagnetic induction matrix layer 14 is laid in a layered manner below the hemisphere structure. Due to the skin effect, the electric field will be concentrated at the top of the sphere of the electromagnetic inductor 15, generating more heat, making it easier for the layered strong electromagnetic induction matrix layer 14 to generate aerosol, and making it easier to solve the problem of insufficient smoke volume release in the first puff of smoke in the composite process. The heated cigarette of this example has been tested by puffing, and its smoke volume is higher than that of conventional heated cigarettes. In particular, the smoke volume in the first puff is increased, the puffing taste is good, and the characteristic flavor is obvious.

[0121] This patent provides a heated cigarette for an electromagnetic induction heating appliance, and the beneficial effects are as follows:

[0122] 1. The aerosol generation matrix is designed in layers. An electromagnetic induction strong emission matrix layer with high smoke emission efficiency is set in the area close to the induction heating body (i.e., the electromagnetic inductor) or the near-mouth end. This layer can quickly release a large amount of aerosol at a relatively low temperature, thus solving the problem of insufficient release of the first puff of smoke. An electromagnetic induction surrounding matrix layer is set in the area far from the induction heating body. This layer releases aerosol at a relatively high temperature to ensure the balance of the overall smoke volume.

[0123] 2. Multi-flavor design. By designing the aerosol generation matrices of different layers to have different flavors (such as tobacco, mint, fruit, etc.), the gradual change or superposition of flavors is achieved during the heating process, enriching the puffing taste experience of the heated cigarette.
