Description

Technical Field

[0001] This patent belongs to the field of novel tobacco technology, specifically relating to an induction-heated cigarette and an aerosol generation system. Background Technology

[0002] Induction-heated cigarettes are a new type of tobacco product that uses a heating element inside the cigarette to generate heat in an electromagnetic field, thereby activating tobacco substances to produce aerosols. The heating principle is that the induction heating element added to the heated cigarette generates an electromagnetic field when the heating device is turned on. The induction heating element absorbs the energy of the electromagnetic field, raising its temperature, and thus heating the tobacco substances to produce atomization.

[0003] Based on its heating principle, induction heating elements require the use of magnetic materials, typically magnetic metals. To improve the utilization rate of tobacco materials, they are usually made into sheet-like inductors, with a portion placed at the center of the electromagnetic field for better heating. Simultaneously, their width is maximized to cover a wider heating range. However, increasing the width leads to higher costs. Therefore, a combination of strongly magnetic metal sheets and weakly magnetic but less expensive metal sheets can be used to increase the heating range without raising costs.

[0004] However, in order to reduce costs and better control the heating temperature, the method of using two or more magnetic materials as composite sensing elements is often adopted. Due to the differences in the physical properties of composite materials, it is difficult to form the composite sheet-like sensing element with the existing smoke-generating material structure of heated cigarettes. This is because the existing smoke-generating material is usually composed of tobacco sheets, which are made by mixing tobacco powder, binder, atomizing agent, fiber, water and other materials in a certain proportion and then flattening them into sheets. When added to heated cigarettes, these sheets need to be shredded (including completely separated filaments and incompletely separated sheets with small widths) and then gathered into a cylinder. However, during the gathering process, due to the large number of pores in the sheet-like sensing element itself, i.e., the gaps between the tobacco sheets during the cigarette forming process, uneven disturbances will occur to the composite heating element, making it difficult to position the sensing element. The position of the sheet-like sensing element may deviate, or it may even break or be stretched and deformed, affecting the heating efficiency. Summary of the Invention

[0005] The purpose of this patent is to provide an induction heating cigarette and aerosol generation system to improve heating efficiency.

[0006] To solve the above-mentioned technical problems, this patent adopts the following technical solution: An induction-heated cigarette, comprising a smoke-generating section, a cooling section, and a filter rod; The smoke-generating section includes the smoke-generating material, induction heating elements, and airflow channels; The fuming substance is in solid form, and its density is 500-2000 kg / m³. 3 ; The airflow channel runs through the smoke-generating material. The induction heating element is arranged in the smoke-generating material, and the induction heating element has a bend point that is not in contact with the airflow channel.

[0007] Furthermore, the cross-sectional area of ​​the airflow channel accounts for 35-40%, 40-50%, 50-60%, 60-70%, or 70-75% of the circular cross-sectional area of ​​the smoke-generating section.

[0008] Furthermore, the induction heating element is the same length as the smoke-generating section.

[0009] Furthermore, the width of the induction heating element is 3-4mm, 4-5mm, or 5-6mm; The thickness of the induction heating element is 0.3-0.4mm, 0.4-0.5mm, 0.5-0.6mm or 0.6-0.8mm.

[0010] Furthermore, the number of airflow channels is set to an even number.

[0011] Furthermore, the bending point is set close to the center of the smoke-generating section.

[0012] Furthermore, the bends are at least partially located between adjacent airflow channels.

[0013] Furthermore, the smoke-generating substances include smoke powder, binders, atomizing agents, fibers, and water.

[0014] Atomizing agents include, but are not limited to: polyols, such as propylene glycol, triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols, such as glycerol monoacetate, glycerol diacetate, or glycerol triacetate; and aliphatic esters of mono-, di-, or polycarboxylic acids, such as dimethyl dodecanoate and dimethyl tetradecanoate. Preferred aerosol forming agents are polyols or mixtures thereof, such as propylene glycol, triethylene glycol, 1,3-butanediol, and most preferably glycerol.

[0015] Preferably, the smoke-generating substance has an atomizing agent content of more than 5% by dry weight. More preferably, the gaseous smoke-generating substance may have an atomizing agent content of between about 5% and about 30% by dry weight. In one embodiment, the smoke-generating substance has an atomizing agent content of about 20% by dry weight.

[0016] Smoke-generating substances for induction-heated cigarettes can be manufactured using existing manufacturing processes in the field, such as rolling, slurry, and papermaking.

[0017] Induction-heated cigarettes can have the shape of traditional cigarettes. Cigarettes and their specifications are typically named according to their length, as follows: "Standard" usually refers to cigarettes in the range of 68mm to 75mm, for example, approximately 68mm to 72mm in length; "Short" or "Mini" refers to cigarettes shorter than 68mm; "Extra-standard" usually refers to cigarettes in the range of 75mm to 91mm, for example, approximately 79mm to 88mm in length; "Long" or "Extra-long" usually refers to cigarettes in the range of 91mm to 105mm, for example, approximately 94mm to 101mm in length; and "Extra-long" usually refers to cigarettes in the range of approximately 110mm to 121mm in length. Additionally, cigarette products are named according to their outer circumference, as described below. The terms "standard" and "extra-fine" refer to cigarettes with a circumference of approximately 23mm to 25mm; "coarse" refers to cigarettes with a circumference of more than 25mm; "fine" refers to cigarettes with a circumference of approximately 22mm to 23mm; "long and thin" refers to cigarettes with a circumference of approximately 19mm to 22mm; "extra-fine" refers to cigarettes with a circumference of approximately 16mm to 19mm; and "micro-fine" refers to cigarettes with a circumference of less than 16mm. Therefore, extra-standard and extra-fine cigarettes have, for example, a length of approximately 83mm and a circumference of approximately 17mm. Standard and extra-standard cigarettes, with a length of 75mm to 91mm and a circumference of 23mm to 25mm, are popular with many customers. Cigarette products of various sizes can also be manufactured with filters of different lengths. Generally, short filters are used for cigarette products with both short length and short circumference. Typically, filter tip lengths range from 15mm, used with "short" and "standard" cigarettes, to 30mm, used with "extra long" and "extra thin" cigarettes. The tipping paper in the longitudinal direction of the cigarette with a filter tip is, for example, 3mm to 10mm longer than the filter tip.

[0018] Preferably, the smoke-generating section, the cooling section, and the filter rod are generally cylindrical and have substantially similar outer diameters. For example, they have an outer diameter of at least 5 mm. Preferably, they have an outer diameter between about 5 mm and about 12 mm, for example, between about 5 mm and about 10 mm, or between about 6 mm and about 8 mm.

[0019] Preferably, the smoke-generating section can have a length between about 5 mm and about 15 mm, for example, between about 8 mm and about 12 mm. In one embodiment, the smoke-generating section can have a length of about 10 mm. In a preferred embodiment, the smoke-generating section has a length of about 12 mm.

[0020] The cooling section can have a total surface area between approximately 300 square millimeters per millimeter of length and approximately 1000 square millimeters per millimeter of length. In a preferred embodiment, the cooling section has a total surface area of ​​approximately 500 square millimeters per millimeter of length.

[0021] The cooling section can be alternatively referred to as a heat exchanger.

[0022] Preferably, the cooling section has low draw resistance. That is, preferably, the cooling section provides low resistance to air passing through the induction-heated cigarette. Preferably, the cooling section has virtually no impact on the draw resistance of the induction-heated cigarette.

[0023] The cooling section may include multiple longitudinally extending channels. These channels may be defined by a sheet material that has undergone one or more of curling, pleating, gathering, and folding to form the channels. Alternatively, the multiple longitudinally extending channels may be defined by a single sheet that has undergone one or more of curling, pleating, gathering, and folding to form multiple channels.

[0024] In some embodiments, the cooling section may include an aggregate of materials selected from the group consisting of: metal foil, polymeric materials, and substantially non-porous paper or paperboard. In some embodiments, the cooling section may include an aggregate of materials selected from the group consisting of: polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polylactic acid (PLA), cellulose acetate (CA), and aluminum foil. In a preferred embodiment, the cooling section includes an aggregate of biodegradable materials. For example, an aggregate of non-porous paper or an aggregate of biodegradable polymeric materials (such as polylactic acid).

[0025] Induction-heated cigarettes may include a filter rod located at the mouth end of the cigarette. The filter rod may be located directly downstream of and adjacent to the cooling section. The filter rod may include a filter tip. The filter tip may be formed of one or more suitable filter materials. Many such filter materials are known in the art. In one embodiment, the filter rod may include a filter tip formed of cellulose acetate tow.

[0026] The filter rod can have a length between approximately 5 mm and approximately 20 mm. In a preferred embodiment, the filter rod has a length of approximately 14 mm. The filter rod can also have a length between approximately 5 mm and approximately 14 mm. In a preferred embodiment, the filter rod has a length of approximately 7 mm.

[0027] The components of an induction-heated cigarette (e.g., the smoke-generating section and any other components of the induction-heated cigarette, such as the cooling section and the filter rod) are surrounded by an outer wrapping paper. Preferably, the outer wrapping paper is cigarette paper.

[0028] An induction heating element is a material that can convert electromagnetic energy into heat. When placed in a fluctuating electromagnetic field, the eddy currents induced in the induction heating element cause it to heat up. When an elongated induction heating element is positioned in thermal contact with a fuming substance, the fuming substance is heated by the induction heating element.

[0029] Induction heating elements can be made of any material capable of being heated inductively to a temperature sufficient to cause fuming substances to generate aerosols. Preferred induction heating elements include metals or carbon. Preferred induction heating elements may include ferromagnetic materials, such as ferrite, ferromagnetic steel, or stainless steel. Suitable induction heating elements may be aluminum or may include aluminum. Preferred induction heating elements may be made of 400 series stainless steel, such as grade 410, 420, or 430 stainless steel. Different materials will consume different amounts of energy when placed in an electromagnetic field with similar frequency and field strength. Therefore, parameters of the induction heating element, such as material type, length, width, and thickness, can be varied within a known electromagnetic field to provide the desired energy consumption.

[0030] The preferred sensor may be heated to temperatures exceeding 250 degrees Celsius. Suitable induction heating elements may include a non-metallic core having a metal layer disposed on the non-metallic core, such as metal traces formed on the surface of a ceramic core.

[0031] The induction heating element may have an outer protective layer, such as a ceramic or glass protective layer encapsulating the elongated induction heating element, thereby forming a complete heating body. The induction heating element may include a protective coating formed of glass, ceramic, or inert metal, which is formed on the core of the induction heating element material.

[0032] This patent also provides an aerosol generation system, including the induction-heated cigarette and aerosol generation device as described above.

[0033] Furthermore, the aerosol generating device includes a housing, a power supply and control components, a heating chamber, and an induction coil; The housing contains power and control components, a heating chamber, and an induction coil. The heating chamber is used to receive at least a portion of the induction-heated cigarette; The induction coil is used as an electromagnetic wave transmitter to provide electromagnetic waves to the induction heating element.

[0034] The aerosol generating device can 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 emitter.

[0035] Preferably, the aerosol generating device is capable of generating a wave electromagnetic field with a field strength (H field) between 1 kA / m and 5 kA / m, for example between 2 kA / m and 3 kA / m, for example about 2.5 kA / m.

[0036] The power source in the aerosol generating device can be any suitable power source, such as a DC voltage source, like a battery. In one embodiment, the power source is a lithium-ion battery. Alternatively, the power source can be a nickel-metal hydride battery, a nickel-cadmium battery, or a lithium-based battery, such as a lithium cobalt, lithium iron phosphate, lithium titanate, or lithium polymer battery.

[0037] This patent provides an induction heating cigarette and aerosol generation system that changes the form of the smoke-generating material from a loose sheet to a compact solid. The structure also has reserved airflow channels, which can tightly wrap the heating element during the molding process, providing better positioning and fixing of the heating element. This fixes the position of the induction heating element in the center of the smoke-generating material, effectively improving heating efficiency and utilization rate of the smoke-generating material.

[0038] Meanwhile, the solid smoke-generating section itself has good structural strength, so the structural support section commonly found in heated cigarettes can be eliminated, which can reduce costs and prevent the high-temperature induction sheet from contacting the surface of the support section and producing odor.

[0039] In addition, the use of a solid smoke-generating section precisely limits the position of the induction heating element, ensuring that the induction heating element is located in the center of the smoke-generating material. This prevents the problem of the induction heating element shifting position and affecting heating efficiency during the production of traditional tobacco sheet heated cigarettes. At the same time, it can be applied to a wider variety of induction heating element structures and shapes, including irregularly shaped heating elements and left-right composite heating elements.

[0050] like Figure 1-2 As shown, the induction-heated cigarette of this patent consists of a smoke-generating section 1, a hollow paper tube 2, a filter rod 3, and packaging paper 4.

[0051] The smoke-generating section 1 includes a solid smoke-generating substance 1.1, an induction heating element 1.2, and an airflow channel 1.3.

[0052] The solid smoke-generating substance 1.1 is composed of smoke powder, binder, atomizing agent, fiber, and water. Its preparation method can be found in the processing technology of raw material B disclosed in Chinese Patent CN115956699A, which includes the following steps: 1) After removing impurities and drying 50g of flue-cured tobacco, pulverize it into tobacco powder of 200 mesh; 2) Thoroughly mix the tobacco powder and auxiliary reagents to form a clump-like mixture; the auxiliary reagents include glycerol as an atomizing agent, chitosan as a binder, bleached coniferous sulfate pulp as an added fiber, and water; wherein, by mass percentage, the atomizing agent is 25%, the binder is 5%, the added fiber is 3%, and the remainder is water; 3) The lumpy mixture is repeatedly kneaded and pressed from multiple directions and angles to form thin sheets; 4) The thin sheet is formed by pressing it with 6 or more sets of rollers; 5) The rolled sheet is dried, shaped, and cut into shreds. First, the sheet coated on the steel strip is heated. Side a of the sheet is heated by steam or electricity through the steel plate, and side b is heated by hot air through a heat exchanger. Then, the sheet is flipped over. Side b of the sheet is heated by steam or resistance through the steel plate, and side a is heated by hot air through a heat exchanger. The sheet is dried until the thickness reaches the specified value of 0.2 mm, and then cut into shreds. The shred width is 1.0 mm and the length is 20 mm, thus obtaining the rolled sheet shreds.

[0053] 6) The thin filaments are dried with hot air at 75℃, and the density obtained by rolling is 1000 kg / m³. 3 1.1 Solid fuming substances.

[0054] The hollow paper tube 2 (i.e. the cooling section) mainly serves a cooling effect. Due to its long length, it can cool down without the need for other cooling methods (such as cooling materials or perforation).

[0055] Filter rod 3 is a conventional cellulose acetate rod.

[0056] The packaging paper 4 tightly wraps and bonds the smoke-generating section 1, the hollow paper tube 2, and the filter rod 3.

[0057] The total length of the induction heating element 1.2 is the same as that of the smoke-generating section 1. The width of the induction heating element 1.2 is 3-6 mm. If the width is too short, the heating range is small; if the width is too long, it will cause the paper to be heated, resulting in an odor. The thickness of the induction heating element 1.2 is 0.3-0.8 mm. If the thickness is too thick or too thin, it will affect the processing performance. In this embodiment, the total width of the induction heating element 1.2 is 5 mm, the thickness of the induction heating element 1.2 is 0.6 mm, and there is a bending point located at the center of the smoke-generating section 1. As another embodiment, the number of bending points can be increased or decreased, and the induction heating element 1.2 can be offset from the center of the smoke-generating section 1.

[0058] There are 6 airflow channels 1.3. The cross-sectional area of ​​the airflow channels 1.3 accounts for 35%-75% of the circular cross-sectional area of ​​the entire smoke-generating section 1. If the cross-sectional area ratio is too large, the amount of smoke-generating material will be reduced, affecting the total suction time. If the cross-sectional area ratio is too small, the preheating time will be longer. In this embodiment, the cross-sectional area accounts for 67% of the circular cross-sectional area of ​​the entire smoke-generating section 1.

[0059] In another implementation, such as Figure 3 As shown, there are 8 airflow channels 1.3, and the cross-sectional area of ​​airflow channels 1.3 accounts for 68.6% of the total circular cross-sectional area of ​​the smoke-generating section 1.

[0060] Another implementation method, such as Figure 4 As shown, there are 6 airflow channels 1.3. The bending point of the induction heating element 1.2 is offset from the center of the smoke-generating section 1. The heating efficiency will be reduced after it is offset from the center, but its manufacturing process will be simpler.

[0061] This patent provides an induction-heated cigarette, in which the smoke-generating material is made into a dense solid, and the induction heating element is located in the center of the smoke-generating material. At the same time, an airflow channel 1.3 is reserved in the solid structure. When the induction heating element heats the smoke-generating material to generate aerosol, the aerosol can be generated from the side wall of the reserved airflow channel 1.3 and transferred to the next section of the heated cigarette through the channel, and finally inhaled into the user's mouth.

[0062] like Figure 5 As shown, this patent also provides an aerosol generation system, which includes an aerosol generation device 200 and the aforementioned induction-heated cigarette.

[0063] The aerosol generating device 200 is arranged to receive induction-heated cigarettes to generate aerosols from the solid smoke-generating substances 1.1 therein.

[0064] The aerosol generating device 200 includes a housing, a power supply and control assembly 210, a heating chamber 220 for receiving at least a portion of an induction-heated cigarette, and an induction coil 230 as an electromagnetic wave transmitter.

[0065] The housing contains a power supply and control assembly 210, a heating chamber 220, and an induction coil 230.

[0066] When the induction heated cigarette is inserted into the aerosol generating device 200, the power supply and control components 210 start the heating mode. The electrical energy of the power supply is provided to the induction coil 230 in the form of alternating current and to the induction heating element 1.2 in the form of electromagnetic waves. After receiving the energy, the induction heating element 1.2 can heat the solid smoke-generating substance 1.1 to generate an aerosol that can be inhaled.
