Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of heated non-combustible smoke appliances, specifically relating to an electromagnetic induction heating smoke appliance with adjustable heating stroke. Background Technology
[0002] Traditional cigarettes require an open flame to produce tobacco aerosol. As people become increasingly health-conscious, the harmful effects of aerosols from the combustion of traditional cigarette products are gaining attention. To mitigate these risks, heated tobacco products (HTPs) have emerged. HTPs are devices that heat the aerosol-generating components of cigarettes. Through energy conversion, they heat the atomizing area of the aerosol-generating component to a specific temperature, producing an aerosol that is then inhaled. This method significantly reduces the tar, carbon monoxide, and other harmful substances produced during combustion, thereby lowering the health risks to smokers and those around them. Traditional heated tobacco devices only achieve an effective volatilization temperature of ≥280℃ in the central heating mode, heating only the area within 5mm of the heating element. The temperature in the outer area is less than 200℃, resulting in a tobacco material utilization rate of less than 40%. To compensate for heat transfer loss, the heating element temperature is usually raised to above 400-450℃, causing the smoke temperature to reach 70-80℃, which is about 15℃ higher than that of traditional cigarettes. High-temperature operation will cause the heating element to age rapidly and is prone to local overheating, which may lead to a fire risk.
[0003] Electromagnetic heating technology boasts significant advantages such as high efficiency, safety, and intelligence, and has become an important development direction in the field of new tobacco products. With technological iteration and standard improvement, its market penetration rate is expected to further increase, but continuous breakthroughs are still needed in areas such as material innovation, energy consumption control, and user experience. Traditional electromagnetic induction heating devices generate a magnetic field by passing alternating current through a coil, causing eddy currents and heating in metal sheets (such as ferromagnetic sheets) within the aerosol-generating product. For example, IQOS Iluma employs a flat coil design, optimizing the magnetic field distribution through dynamic frequency control to improve energy efficiency. An induction sheet (such as an aluminum foil layer) built into the aerosol-generating product assists in preheating the airflow, enhancing heating uniformity.
[0004] However, such electromagnetic heating devices require a built-in metal plate in each heated cigarette. The device must be able to identify the electromagnetic properties of the specific heated cigarette to prevent the use of third-party products. While this creates a technological barrier, it also results in a waste of metal plate material. Therefore, it is necessary to design an electromagnetic induction heating device that can adapt to different heated cigarette sizes, has an adjustable heating stroke, provides uniform heating, and is highly hygienic, in order to enhance the consumer's smoking experience. Utility Model Content
[0005] The purpose of this patent is to obtain an electromagnetic induction heating device that can adapt to heated cigarettes of different sizes, has an adjustable heating stroke, provides uniform heating, and is easy to clean.
[0006] To solve the above technical problems:

The heating module is located in the lower part of the heating chamber. The heating module includes an inductor, a sliding sleeve, and a pusher. The inductor is located inside the sliding sleeve, and the pusher is located below the inductor. The pusher is used to adjust the heating stroke of the inductor, so that the inductor rotates along the sliding sleeve, passes through the threaded hole that matches the inductor, and is inserted into the aerosol-generated product located in the heating chamber.
[0009] Furthermore, the power supply module provides power to the induction coil. When the electromagnetic induction heating smoke device is energized, after the inductor is inserted into the aerosol generating product, the inductor and the induction coil generate electromagnetic induction, which can heat the aerosol generating product.
[0010] Furthermore, the inductor includes a heating body and a conical guide section that is smoothly connected to the heating body, and the outer peripheral surface of the inductor is provided with threads.
[0011] Furthermore, a sliding sleeve is fitted onto the outside of the sensor, and a spiral channel is provided on the inner wall of the sliding sleeve; the sensor is engaged with the spiral channel through a thread, so that the sensor reciprocates along the axial direction of the sensor.

[0015] Furthermore, a knob is provided at the lower part of the booster, and the knob protrudes from the outer surface of the electromagnetic induction heating smoke device; by rotating the knob to adjust the booster, the slider located on the inductor moves along the booster track, the inductor passes through the slide sleeve and is inserted into the heating chamber, and the inductor generates axial displacement, moving from the first position to the second position.
[0016] Furthermore, the axial displacement of the inductor is the heating stroke, which is 0–0.5 cm, 0.5–1.0 cm, or 1.0–2.0 cm.

[0018] Furthermore, the inductor and the induction coil are arranged coaxially, and a magnetic shielding layer is provided on the outside of the induction coil. When energized, the induction coil generates an induced magnetic field, which causes the inductor to heat the aerosol to form the matrix segment of the product.
[0019] Among them, aerosol generating products are smoking products, including an aerosol forming matrix (located within the matrix segment), which generates aerosols through heating that can be directly inhaled into the user's lungs through the user's mouth.

[0022] For example, the aerosol-forming material can be formed from a sheet of homogeneous tobacco. Alternatively or additionally, the aerosol-forming matrix can include a tobacco-free aerosol-forming material. For example, the aerosol-forming material can be a sheet comprising nicotine salts and an aerosol-forming agent.
[0023] If the aerosol forming matrix is a solid aerosol forming matrix, then 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 homogeneous tobacco.
[0024] 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.
[0025] 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.
[0026] The aerosol forming matrix can be in the form of a plug, which includes an aerosol forming material defined by paper or other packaging material. In the case where the aerosol forming matrix is in the form of a plug, an integral plug comprising any packaging paper is considered to be an aerosol forming matrix.
[0027] Preferably, the aerosol forming matrix includes a plug, said plug comprising an aggregate of homogeneous tobacco material or other aerosol forming material surrounded by packaging material.
[0028] In this patent, "aerosol forming agent" is used to describe any suitable known compound or mixture of compounds that promotes aerosol formation in use and is substantially resistant to thermal degradation at the operating temperature of the aerosol-generated article.
[0029] Suitable aerosol forming agents are known in the art and 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.
[0030] The aerosol forming matrix may include a single aerosol forming agent. Alternatively, the aerosol forming matrix may include a combination of two or more aerosol forming agents.
[0031] Preferably, the aerosol forming matrix has an aerosol forming agent content of more than 5% by dry weight. More preferably, the aerosol forming matrix may have an aerosol forming agent content between about 5% and about 30% by dry weight. In one embodiment, the aerosol forming matrix has an aerosol forming agent content of about 20% by dry weight.
[0032] Preferably, the aerosol forming article includes an aerosol forming matrix, a support section, and a filter section. Preferably, the aerosol forming matrix, the support section, and the filter section are generally cylindrical and have substantially similar outer diameters.
[0033] An aerosol generating device is used to describe an apparatus that interacts with an aerosol-forming matrix of an aerosol-generating article to generate an aerosol. Preferably, the aerosol generating device is a heated smoking device that interacts with the aerosol-generating matrix of the aerosol-generating article to generate an aerosol that can be directly inhaled into the user's lungs through the user's mouth. The aerosol generating device can also be a holder for a smoking article.
[0034] An inductor is a material that can convert electromagnetic energy into heat. When placed in a undulating electromagnetic field, the eddy currents induced in the inductor cause it to heat up. When an elongated inductor is positioned in thermal contact with an aerosol-forming matrix, the aerosol-forming matrix is heated by the inductor.
[0035] The aerosol generating article is designed to engage with an electrically operated aerosol generating device, including an induction heating source. The induction heating source or sensor generates a fluctuating electromagnetic field to heat an inductor located within the fluctuating electromagnetic field. In use, the aerosol generating article is engaged with the aerosol generating device such that the inductor is located within the fluctuating electromagnetic field generated by the sensor.
[0036] The inductor can be made of any material capable of being heated inductively to a temperature sufficient to generate an aerosol matrix. Preferred inductors include metals or carbon. Preferred inductors may include ferromagnetic materials, such as ferrite, ferromagnetic steel, or stainless steel. Suitable inductors may be aluminum or may include aluminum. Preferred inductors 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 inductor, such as material type, length, width, and thickness, can be varied within a known electromagnetic field to provide the desired energy consumption.
[0037] The preferred inductor may be heated to a temperature exceeding 250 degrees Celsius. A suitable inductor 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.
[0038] The sensor may have an outer protective layer, such as a ceramic or glass protective layer encapsulating the elongated sensor, thereby forming a complete sensor. The sensor may include a protective coating formed of glass, ceramic, or inert metal, which is formed on the core of the sensor material.
[0039] The inductor is arranged in thermal contact with the aerosol forming matrix. Therefore, when the inductor is heated, the aerosol forming matrix is heated and an aerosol is formed. In one embodiment, the inductor, including the sensor, is inserted into the aerosol forming matrix, and the aerosol generating apparatus may include one or more elongated inductors.
[0040] 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.
[0041] 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.
[0042] The induction coil material should be a material with good conductivity, such as metal; in addition, in this patent, the induction coil material should also have good elastic deformation ability, and can be spring steel, gold, silver or other metals.
[0043] The movable coil support and fixed coil support of the induction coil can be connected to the induction coil body through methods such as integral molding, welding, or clamping. The displacement of the movable coil support can be achieved manually or by motor drive.
[0044] An aerosol generator is a portable or handheld device that can be comfortably held between the fingers of one hand. The shape of the aerosol generator is generally cylindrical. The aerosol generator can have a length between approximately 70 mm and approximately 120 mm.
[0045] The power source 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.
[0046] The control element can be a simple switch. Alternatively, the control element can be a circuit and may include one or more microprocessors or microcontrollers.
[0047] An aerosol generation system may include an aerosol generation device and one or more aerosol generation articles, wherein the aerosol generation device is configured with a corresponding number of heating chambers to contain the aerosol generation articles.
[0048] Compared with existing technologies, this patent has the following beneficial effects:
[0049] 1. The present invention provides an electromagnetic induction heating smoke device with adjustable heating stroke. By setting an induction coil in the heating chamber and setting an induction body that can reciprocate in the heating module, the induction body can be accurately pushed into the center of the matrix section of the aerosol generating product and set coaxially with the induction coil, so as to achieve uniform heating of the aerosol generating product, avoid puncturing the outer wrapping paper of the aerosol generating product, and is applicable to aerosol generating products of different sizes.
[0050] 2. A threaded hole is provided at the center of the bottom of the heating chamber to match the external thread of the sensor body. This allows the tobacco matrix remaining on the sensor body to be blocked in the heating chamber when the sensor body is heated and reciprocating, making it easy to clean and improving the smoking experience of the independent aerosol generation product.

[0088] To make the objectives, technical solutions, and advantages of this patent clearer, the embodiments of this patent will be described in further detail below with reference to the accompanying drawings.
[0089] like Figure 1-10 The illustration shows a specific embodiment of this patent. This patent provides an electromagnetic induction heating smoke appliance with adjustable heating stroke. The electromagnetic induction heating smoke appliance includes a heating chamber 2, a heating module 3, a control module 4, a drive module 5, and a power supply module 6. The heating chamber 2 is used to accommodate the aerosol generating product 1. An induction coil 21 is provided on the inner wall of the heating chamber 2, and a spiral hole 22 is provided at the bottom of the heating chamber 1. The heating module 3 is located at the lower part of the heating chamber 2. The heating module 3 includes an inductor 31, a sliding sleeve 32, and a pusher 33. The inductor 31 is located inside the sliding sleeve 32. The booster 33 is located at the lower part of the inductor 31. The booster 33 is used to adjust the heating stroke of the inductor 31, so that the inductor 31 rotates along the slide sleeve 32, passes through the threaded hole 22 that is adapted to the inductor 31, and is inserted into the aerosol generating product 1 located in the heating chamber 2. The power supply module 5 provides power to the induction coil 21. When the electromagnetic induction heating smoke appliance is in the energized state, after the inductor 31 is inserted into the aerosol generating product 1, the inductor 31 and the induction coil 21 generate electromagnetic induction to heat the aerosol generating product 1.
[0090] Specifically, the aerosol generating product 1 includes a filter rod segment 11, a support segment 12, and a matrix segment 13.
[0091] Specifically, an induction coil 21 is provided on the inner wall of the heating chamber 2, and the induction coil 21 is arranged circumferentially along the inner wall of the heating chamber 2. The inner wall of the induction coil 21 is used to receive the aerosol-generated product 1, and the outer wall of the induction coil 21 is provided with a magnetic shielding layer.
[0092] The induction coil generates a divergent magnetic field in the working chamber. The magnetic shielding layer, made of a high-permeability material, forms a low magnetic reluctance channel, confining the induction coil inside the magnetic shielding layer. This effectively reduces magnetic leakage and significantly improves energy transmission efficiency. At the same time, the magnetic shielding layer can also attenuate external stray magnetic fields, such as reducing the interference of magnetic fields from nearby equipment on the induction coil.
[0093] Specifically, the material of the induction coil 21 should be a material with good conductivity, such as metal; in addition, in this patent, the material of the induction coil 21 should also have good elastic deformation ability, and can be spring steel, gold, silver or other metals.
[0094] Specifically, the bottom of the heating chamber 2 is also provided with a threaded hole 22.
[0095] Specifically, the heating module 3 is located at the lower part of the heating chamber 2, and the heating module 3 includes an inductor 31, a sliding sleeve 32, and a booster 33.
[0096] Specifically, the sensor 31 is cylindrical in shape and includes a heating body 311 and a conical guide section 312 that is smoothly connected to the heating body.
[0097] Specifically, the conical guide section 312 is located on the inductor 31 at one end near the aerosol generating article 1. The conical guide section 312 is integrally connected with the heating body 311, and the conical guide section 312 and the heating body 311 are smoothly connected to ensure that the resistance experienced by the inductor 31 when it is inserted into the aerosol generating article 1 is as small as possible.
[0098] Specifically, the outer peripheral surface of the inductor 31 is provided with threads. Specifically, the heating body 311 and the conical guide section 312 are provided with threads.
[0099] Specifically, the inductor 31 also includes a base 313, which is located at the lower part of the inductor 31, that is, at the end away from the aerosol generating product 1. The base 313 is integrally connected with the heating body 311 and the conical guide section 312.
[0100] Specifically, at least one slider is provided on the base 313. Preferably, two sliders, namely slider 314a and slider 314b, are symmetrically arranged on the base.
[0101] Specifically, the inductor 31 is a material that can convert electromagnetic energy into heat. When the inductor 31 is located in a fluctuating electromagnetic field, the eddy currents induced in the inductor 31 cause the inductor 31 to heat up. When the elongated inductor 31 is positioned to make thermal contact with the tobacco matrix in the matrix segment 13 of the aerosol forming article 1, the aerosol forming matrix is heated by the inductor 31.
[0102] Specifically, the inductor 31 can be made of any material that can be heated by electromagnetic induction to a temperature sufficient to generate aerosols from the tobacco matrix in the matrix segment 13 of the aerosol generation article 1.
[0103] Preferably, the sensor 31 comprises a metal or carbon. Preferably, the sensor 31 may comprise a ferromagnetic material, such as ferrite, ferromagnetic steel, or stainless steel.
[0104] Preferably, the inductor 31 can be made of 400 series stainless steel, such as grade 410, 420, or 430 stainless steel. When placed in an electromagnetic field with similar frequency and field strength, different materials will consume different amounts of energy.
[0105] Therefore, the parameters of the inductor 31, such as material type, length, width and thickness, can be changed within a known electromagnetic field to provide the required energy consumption.
[0106] Specifically, the sensor 31 may have an outer protective layer, such as a ceramic protective layer or a glass protective layer that encapsulates the elongated sensor 31, thereby forming a complete sensor 31.
[0107] The sensor 31 may include a protective coating formed of glass, ceramic or inert metal, the protective coating being formed on the core of the sensor 31 material.
[0108] Specifically, the sliding sleeve 32 is sleeved on the outside of the sensor 31. The sliding sleeve 32 includes a sleeve body 321. A spiral channel 322 is provided on the inner wall of the sleeve body 321. The spiral channel 322 is a spiral guide groove. The sensor 31 is engaged with the spiral channel 322 through a thread, so that the sensor 31 reciprocates along the axial direction of the sensor 31.
[0109] This can be understood as follows: the thread on the sensor 31 and the spiral channel 322 on the slide sleeve 32 form an adjustable spiral pair connection; the thread on the sensor 31 is an external thread, which meshes with the spiral guide groove on the slide sleeve 32 through the phase in the circumferential direction, that is, the thread helix angle on the sensor 31 is the same as the thread helix angle of the spiral guide groove. The two form a spiral transmission pair under axial action, so that the sensor 31 can reciprocate along the axial direction of the sensor 31.
[0110] Specifically, the booster 33 is located at the lower part of the sensor 31. The booster 33 is sleeved on the outside of the slide sleeve 32. The booster 33 is provided with at least one booster track, so that the slider on the sensor 31 can extend into the booster track and reciprocate along the booster track.
[0111] Preferably, the booster 33 is provided with two booster tracks, namely booster track 331a and booster track 331b. Booster track 331a and booster track 331b are symmetrically arranged. Slider 314a on the sensor slides along booster track 331a and slider 314b slides along booster track 331b, so that slider 314a and slider 314b on the sensor are on the same horizontal plane.
[0112] Specifically, the heating module 3 also includes a knob 34, which is located at the lower part of the booster 33 and protrudes from the outer surface of the electromagnetic induction heating smoke device.
[0113] When the power supply module 6 does not supply power to the induction coil 21, the electromagnetic induction heating smoke appliance is in a non-working state. At this time, the entire induction body 31 is completely located inside the sliding sleeve 32, that is, the induction body 31 is in the first position.
[0114] When the power supply module 6 supplies power to the induction coil 21, the electromagnetic induction heating smoke appliance is in working condition. By rotating the knob 34, the pusher 33 is mechanically adjusted, causing the slider on the induction body 31 to move along the pusher track. The threads on the induction body 31 cooperate with the spiral channel 322 on the slide sleeve 32, so that the induction body 31 passes through the slide sleeve 32 and the threaded hole 33 at the bottom of the heating chamber 2 and extends into the heating chamber 2. At this time, the induction body 31 is located inside the heating chamber 2, that is, the induction body 31 is in the second position.
[0115] It can be understood that the heating stroke of the inductor 31 can be adjusted according to the length of the aerosol-generated product 1. That is, the entire inductor 31 can be located inside the heating chamber 2, or the inductor 31 can be partially inserted into the heating chamber 2. Here, the inductor 31 being partially inserted into the heating chamber 2 means that the conical guide section 312 is inserted into the heating chamber 2, or the conical guide section 312 together with part of the heating body 311 is inserted into the heating chamber 2.
[0116] The axial displacement of the inductor 31 as it moves from the first position to the second position is the heating stroke of the inductor 31. Specifically, the heating stroke of the inductor 31 is 0-0.5 cm, 0.5-1.0 cm, or 1.0-2.0 cm.
[0117] Specifically, the threaded hole 22 is located at the center of the bottom of the heating chamber 2. The inductor 31 passes through the sliding sleeve 32 and the threaded hole 22 in sequence and is inserted into the matrix section 13 of the aerosol generating product 1 in the heating chamber 2, so that the inductor 31 is located at the center of the matrix section 13, thereby achieving uniform heating of the aerosol generating product 1.
[0118] Specifically, the internal thread on the threaded hole 11 and the external thread on the inductor 31 have the same thread helix angle, so that the internal thread and the external thread mesh.
[0119] Specifically, the inductor 31 and the induction coil 22 are arranged coaxially.
[0120] When using an electromagnetic induction heating device for inhalation, the inductor 31 passes through the threaded hole 22 on the heating chamber 2 and precisely inserts into the matrix section 13 of the aerosol generating product 1. An induction magnetic field is generated between the induction coil 22 and the inductor 31, causing the inductor 31 to heat the matrix section 13 of the aerosol generating product 1.
[0121] After using the electromagnetic induction heating device, by rotating the knob 34, the external thread on the sensor 31 engages with the internal thread on the threaded hole 22, causing the sensor 31 to move away from the aerosol generating product 1. At this time, the tobacco matrix remaining on the sensor 31 will be blocked in the heating chamber 2, making it easier to clean the heating chamber 2 of the electromagnetic induction heating device and improving the smoking experience of the independent aerosol generating product 1.
[0122] Specifically, the control module can be a simple switch. Alternatively, the control element can be a circuit and may include one or more microprocessors or microcontrollers.
[0123] Specifically, the drive module drives the power supply module to transmit power to the induction coil.
[0124] Therefore, it can be concluded that the electromagnetic induction heating smoke hood with adjustable heating stroke provided by this utility model has the following advantages over the prior art:
[0125] 1.
