Description

Technical Field

[0001] This invention relates to the field of tobacco product technology, and more specifically to an aerosol generating product and system. Background Technology

[0002] Aerosol-generating products, such as modern electronic cigarettes or heated tobacco products, are gradually becoming alternatives to traditional tobacco products, aiming to provide users with a safer and cleaner smoking experience.

[0003] Traditional tobacco products rely on combustion to generate aerosols, a process that often results in the formation of numerous harmful substances. For example, burning tobacco releases tar, carbon monoxide, heavy metals, and other harmful substances that pose a serious threat to human health. Therefore, combustion-based aerosol generation technology has significant safety shortcomings.

[0004] HNB (Heat Not Burn), also known as low-temperature cigarettes, is a new type of tobacco product that combines a heating device and a tobacco cartridge. Designed with the concept of "heating without burning," it uses a special heating device (such as a smoking device) to heat processed tobacco (such as a special tobacco cartridge) to a certain temperature, enough to release smoke for inhalation. Its advantages include reduced harm and restoration of the pure taste and throat hit of traditional cigarettes, providing smokers with a smoking alternative that is closest to traditional cigarettes.

[0005] HNB-related aerosol generation systems use various heating mechanisms to convert aerosol-generating materials containing nicotine, flavorings, and other ingredients into aerosols for users to inhale. However, despite significant progress in reducing harmful substances, these novel aerosol-generating products still face numerous challenges. For example, some HNB systems heat the aerosol-generating materials using air heating or media heating (such as inserts), but these methods often suffer from uneven heating and slow temperature rise in practical applications. Uneven heating can lead to poor aerosol generation, affecting the user experience; while slow temperature rise limits the efficiency and speed of aerosol generation, requiring users to wait longer to obtain the desired aerosol.

[0006] Furthermore, while existing technologies mention using propylene glycol / glycerol-coated capsules as aerosol-generating matrices, most related technologies merely use capsules as a supplement to tobacco materials. Some patents also mention using pure capsules directly as aerosol-generating materials and placing them in the aerosol-generating matrix section; however, these technologies all use single capsules and require addressing the issue of core material leakage after capsule rupture, for example, by using absorbent pads to absorb the capsule core material. It is evident that the relevant technical literature does not explicitly propose how to efficiently heat the aerosol-generating capsules to improve aerosol release efficiency, nor does it solve a series of technical problems associated with directly using capsules as aerosol-generating materials. Summary of the Invention

[0007] The technical problem solved by this invention is how to improve the efficiency of aerosol generation, reduce the heating release temperature, and at the same time reduce the generation of harmful substances.

[0008] To address the aforementioned technical problems, this invention provides an HNB product, namely an aerosol generation article, comprising an aerosol generation matrix segment. The aerosol generation matrix segment includes aerosol generation capsules and a sensor. The sensor can generate heat under the influence of an electromagnetic field to heat the aerosol generation capsules. The aerosol generation capsules, as aerosol generation material, have a lower heating release temperature, thus enabling faster smoke release during electromagnetic heating. Simultaneously, as spherical structures, the aerosol generation capsules can form continuous voids during filling, allowing the heat emitted by the sensor to be more smoothly transferred to each capsule, thereby improving the continuity and uniformity of aerosol release and further reducing the heating temperature.

[0009] Optionally, the aerosol-generating capsule includes a core material and a shell encapsulating the core material. The core material is a colloid, paste, or solid-liquid mixture. Liquid core materials have good flowability and are less likely to adhere to the capsule shell. If the core material is not a pure liquid or has a certain viscosity, it is easier to adhere to the capsule shell even after heating, which can effectively prevent the core material from flowing out of the aerosol-generating product.

[0010] Optionally, the aerosol-generating capsule includes a core material and a shell encapsulating the core material, wherein the core material includes at least one of propylene glycol and glycerol. Preferably, the core material includes both propylene glycol and glycerol. Propylene glycol and glycerol are common smoke-generating agents, and their combined use achieves a balance between rapid release and smoke effect, realizing the goal of releasing sufficient smoke at low temperatures.

[0011] Optionally, the aerosol-generating capsule includes a core material and a shell encapsulating the core material, the shell having a thickness of 50–150 μm. A higher shell thickness increases the difficulty of capsule rupture under heat, reducing the release rate; a lower shell thickness results in insufficient capsule strength and makes it difficult to manufacture and process.

[0012] Optionally, the particle size of the aerosol generating capsule is 1-3 mm, preferably 1.5-2.5 mm. When the smoke release is designed to be the same, if the capsule particle size is too small, the amount of core material in each capsule is lower. Although the uniformity of release will improve, it will also lead to a decrease in the carrying capacity of the smoke-generating agent and a reduction in the filling porosity, all of which adversely affect the smoke release effect. Therefore, a suitable particle size, especially a moderate particle size, can ensure a good inhalation experience and also prevent the problem of large-diameter capsule core material flowing out of the aerosol generating product.

[0013] Optionally, the filling amount of the aerosol generating capsule is 0.05-0.5g, preferably 0.1-0.3g. When the amount of smoke released is constant, a higher filling amount may lead to material waste, while a lower filling amount will reduce the persistence of aerosol generation. Therefore, a moderate filling amount can ensure a good inhalation experience.

[0014] Optionally, the aerosol generating capsules are filled with 5 to 100 capsules, preferably 15 to 30 capsules. When the smoke release is designed to be the same, a lower number of capsules may result in too much core material in each capsule, which may cause the core material to flow out of the aerosol generating product; while a higher number of capsules will lead to an increase in draw resistance, affecting the vaping experience; at the same time, an appropriate filling amount can also ensure the uniformity of smoke release.

[0015] Optionally, the aerosol generating matrix segment does not include other aerosol generating materials besides the aerosol generating capsule. Since different aerosol generating materials have different heating release temperatures, the aerosol generating capsule can release at a lower temperature, thus further reducing the heating release temperature. Using a single type of aerosol generating material, such as the aerosol generating capsule, can maintain release efficiency while using a lower heating release temperature, thereby saving energy and reducing potentially harmful components released at high temperatures.

[0016] Optionally, the thickness of the sensor 107 is between 10 and 100 μm. A suitable sensor thickness can ensure good heating efficiency.

[0017] Optionally, the receptor is located at the radial center of the aerosol generation matrix segment and extends axially. Positioning the receptor centrally ensures effective thermal contact with more capsules, achieving uniform heating from the center outwards and improving the uniformity of aerosol release.

[0018] Optionally, the sensor can be sheet-shaped, hollow cylindrical, or impeller-shaped. A sheet-shaped sensor can be located at the center of the aerosol generating product tube; a hollow cylindrical sensor can be filled with aerosol generating capsules both inside and out, with its geometric center located at the center; an impeller-shaped sensor can transfer heat to the surrounding area more quickly through the impeller blades, effectively improving heat transfer efficiency and heating uniformity.

[0019] Optionally, the sensor may comprise a metallic material, preferably stainless steel. Metallic materials are the preferred material for electromagnetic heating sensors and generally possess good electrical and thermal conductivity.

[0020] Optionally, the sensor includes a non-metallic material and a metallic material layer in contact with the non-metallic material. The non-metallic material can provide protection for the metallic material, improving the stability of the product.

[0021] Optionally, there may be multiple sensors. Arranging multiple sensors in combination can also improve the uniformity and efficiency of heating.

[0022] The present invention also provides an aerosol generation system, including the above-mentioned aerosol generation article and an electromagnetic heating device for heating the aerosol generation article. The aerosol generation matrix segment of the aerosol generation article is inserted into the electromagnetic heating device. The electromagnetic heating device generates a fluctuating electromagnetic field acting on the receptors inside the aerosol generation matrix segment, causing the receptors to heat up and heating the aerosol generation capsule through heat transfer.

[0023] Optionally, the heating power of the electromagnetic heating device is 1 to 8 W. Considering the need for heating efficiency and uniformity of release, the electromagnetic heating power can fluctuate within a certain range, and the power can also be adjusted according to the heating and release stages during the actual heating process.

[0024] Optionally, the frequency of the fluctuating electromagnetic field is between 1 MHz and 30 MHz. A suitable frequency can ensure sufficient heating efficiency.

[0025] In existing technologies, the aerosol generating materials used in HNB products are mainly tobacco sheets, tobacco particles, and solid-formed cigarette cores. Even with electromagnetic heating, their heating release efficiency is relatively low. Furthermore, after the material near the sensor is heated and released, it surrounds the sensor, reducing heat transfer to materials farther away. Heating and releasing the edge materials is difficult, resulting in weak smoke persistence. The technical solution of this invention uses an aerosol generating capsule as the aerosol generating material, which can lower the heating release temperature, thereby achieving faster smoke release efficiency during electromagnetic heating and exhibiting good heat transfer performance, resulting in better smoke persistence. Compared to heating the aerosol generating capsule using traditional heating methods, electromagnetic heating can quickly heat the sensor to the required temperature, thereby rapidly heating the aerosol generating capsule to generate aerosols. This also significantly shortens the preheating start-up time and improves the efficiency of aerosol generation. Attached Figure Description

[0028] Figure 3 This is a schematic diagram of an aerosol generation system according to an embodiment of the present invention. Detailed Implementation

[0029] As described in the background section, existing HNB aerosol generation systems mainly heat aerosol generating materials, such as tobacco sheets, tobacco particles, and solid tobacco core materials, through heat transfer. This has the drawbacks of slow heating rate and the tendency to generate unintended harmful substances.

[0030] To address the aforementioned technical problems, embodiments of the present invention provide an aerosol generation product and system, wherein the aerosol generation product includes an aerosol generation matrix segment, the aerosol generation matrix segment includes an aerosol generation capsule and a sensor, and the sensor can generate heat under the action of an electromagnetic field to heat the aerosol generation capsule.

[0031] This invention relates to a method that introduces a sensor that heats up under the influence of an electromagnetic field to create aerosol-generating capsules. Electromagnetic heating rapidly raises the sensor to the required temperature, thus quickly heating the aerosol-generating capsules to produce aerosols. This significantly shortens the preheating start-up time and improves the efficiency of aerosol generation. Compared to traditional heating methods, such as air heating or medium heating, electromagnetic heating has a faster temperature rise rate and can reach a stable operating state more quickly.

[0032] To make the above-mentioned objectives, features and beneficial effects of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Figure 1 This is a schematic diagram of an aerosol-generating product 10 according to an embodiment of the present invention. Figure 2 yes Figure 1 A schematic diagram of the receptor 107. Figure 3 This is a schematic diagram of an aerosol generation system according to an embodiment of the present invention.

[0034] Combination Figures 1 to 3 In some embodiments, the aerosol generating article 10 may include an aerosol generating matrix segment 101, which includes an aerosol generating capsule 104 and a receptor 107. The receptor 107 can generate heat under the action of an electromagnetic field to heat the aerosol generating capsule 104.

[0035] Furthermore, the aerosol generating capsule 104, which is filled in the aerosol generating matrix section 101, can rupture when heated and generate aerosols that can be inhaled by the user.

[0036] In a typical application scenario, when the aerosol generating capsule 104 is heated by an external heat source, its volatile components begin to vaporize. These components may include, for example, nicotine, flavorings, glycerin, etc., which gradually change from a solid or liquid (or a solid-liquid mixture) state to a gaseous state during heating. Further, the vaporized volatile components cool in the air and condense into tiny particles, which are the components of the aerosol. The formed aerosol particles are inhaled into the lungs by the user through the act of smoking. During inhalation, the aerosol particles can deposit in the respiratory tract and release their active ingredients, such as nicotine.

[0037] In some embodiments, the aerosol generating capsule 104 includes a core material and a shell encapsulating the core material. The shells of multiple aerosol generating capsules 104 are capable of rupturing when a certain temperature condition is met to release the core material and generate aerosol. The heating release temperature of the aerosol generating capsule is generally between 180 and 300°C, preferably 200 to 250°C, and is related to the material and thickness of the capsule shell.

[0038] Furthermore, the receptor 107 can be connected to an external device (e.g., a... Figure 3 The sensor 107 heats up under the influence of a wave electromagnetic field provided by the sensor (in the middle). When the wave electromagnetic field acts on the sensor 107, the sensor 107 can rapidly heat up and heat the aerosol generation capsule 104 in contact with it through heat transfer. This optimizes the aerosol generation process and improves the heating and release efficiency.

[0039] In some embodiments, the core material inside the aerosol generating capsule 104 is liquid.

[0040] In some embodiments, the capsule core material is in the form of a paste, a colloid, or a solid-liquid mixture.

[0041] In some embodiments, the core material may include an aqueous liquid formulation containing a fuming substance that can be released by heating, the fuming substance including propylene glycol and glycerol, the shell comprising a colloidal substance, the colloidal substance being at least one of animal glue, plant glue, microbial glue, starch and starch modifiers, and the aerosol generating capsule 104 comprising only one shell layer.

[0042] In some specific embodiments of the aerosol generating capsule 104 of the present invention, the aqueous liquid preparation is water or a liquid preparation that can be uniformly dispersed in water molecules to form a solution, such as ethanol, glycerol, or propylene glycol, etc.

[0043] In some specific embodiments of the aerosol-generating capsule 104 of the present invention, the aqueous liquid formulation accounts for 5-60 wt% of the weight of the core material; in some specific embodiments, the aqueous liquid formulation accounts for 15-50 wt% of the weight of the core material; in some specific embodiments, the aqueous liquid formulation accounts for 25-45 wt% of the weight of the core material, and for example, it can be 25 wt%, 30 wt%, 35 wt%, 40 wt%, or 45 wt%, etc.

[0044] In some embodiments of the aerosol-generating capsule 104 of the present invention, the propylene glycol and glycerol account for more than 80 wt% of the total weight of the aqueous liquid formulation; in some embodiments, the propylene glycol and glycerol account for more than 85 wt% of the total weight of the aqueous liquid formulation; in some embodiments, the propylene glycol and glycerol account for more than 90 wt% of the total weight of the aqueous liquid formulation; in some embodiments, the propylene glycol and glycerol account for more than 95 wt% of the total weight of the aqueous liquid formulation; and in some embodiments, the propylene glycol and glycerol account for 100 wt% of the total weight of the aqueous liquid formulation.

[0045] In some specific embodiments of the aerosol-generating capsule 104 of the present invention, the capsule core material further includes 0.1 to 20 wt% of fragrance, extract, nicotine and / or nicotine salt, which may be animal extracts or plant extracts, such as musk, ambergris, tea extract, monk fruit extract, etc.

[0046] In some specific embodiments of the aerosol-generating capsule 104 of the present invention, the capsule core material further includes an oily preparation and a structural agent; the structural agent includes cellulose and / or cellulose derivatives, low molecular weight lipids, and surfactants, and the core material is a paste, a colloid, or a solid-liquid mixture. The combination of the cellulose and / or cellulose derivatives and the low molecular weight lipids facilitates the formation of a network structure in the oily preparation that promotes the dispersion and fixation of propylene glycol and glycerol. The surfactants contribute to the formation of an oil film between the core material and the shell layer, thereby facilitating the encapsulation of the core material by the shell. The core material formed by the propylene glycol and glycerol, the oily preparation, and the structural agent is in the form of a paste, a colloid, or a solid-liquid mixture at room temperature (25°C), which facilitates the stable encapsulation of the core material by the shell.

[0047] It should be clarified that the use of oily agents and structural agents in the core material is only one means of coating propylene glycol and glycerol. In order to coat propylene glycol and glycerol, other known encapsulation methods in the existing technology can also be used, such as photocuring dripping, coating and spheroidizing, cryo-coating, coagulation, etc.

[0048] In some embodiments, the thickness of the housing is 50–150 μm.

[0049] In specific embodiments of the aerosol-generating capsule 104 of the present invention, considering the influence of shell thickness on the strength and aerosol release amount of the aerosol-generating capsule 104, in some specific embodiments, the shell thickness is 50–150 μm, specifically, for example, 50 μm, 60 μm, 70 μm, 80 μm, 90 μm, 100 μm, 110 μm, 120 μm, 130 μm, 140 μm, or 150 μm, etc. This ensures both the structural stability and heating efficiency of the aerosol-generating capsule 104, while also generating high-quality aerosols. Simultaneously, this range also provides a degree of flexibility, allowing for fine-tuning according to different core material compositions, heating conditions, and product requirements.

[0050] In some specific embodiments of the aerosol generating capsule 104 of the present invention, considering the aerosol release effect, the particle size of the aerosol generating capsule 104 is 1 to 3 mm, specifically, it can be 1 mm, 1.5 mm, 2 mm, 2.5 mm or 3 mm, etc.

[0051] In a preferred embodiment, the aerosol generating capsule 104 has a particle size of 1.5 to 2.5 mm.

[0052] In one specific embodiment, at least one of the plurality of aerosol generating capsules 104 has a particle size different from that of the other aerosol generating capsules 104.

[0053] In some specific embodiments of the aerosol generating capsule 104 of the present invention, considering the duration of a user's single use of the aerosol generating product 10 (e.g., characterized by the number of pouches), the filling amount of the aerosol generating capsule 104 is 0.05 to 0.5 g, specifically, for example, 0.05 g, 0.1 g, 0.15 g, 0.2 g, 0.25 g, 0.3 g, 0.35 g, 0.4 g, 0.45 g, or 0.5 g, etc.

[0054] In a preferred embodiment, the aerosol generating capsule 104 has a filling amount of 0.1 to 0.3 g.

[0055] In some specific embodiments, the aerosol generating capsule 104 has a filling amount of 5 to 100 capsules, specifically, for example, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, etc.

[0056] In a preferred embodiment, the aerosol generating capsule 104 is filled with 15 to 30 capsules.

[0057] In some embodiments, the aerosol generating matrix segment 101 does not include other aerosol generating materials besides the aerosol generating capsule 104.

[0058] Therefore, by rationally configuring the shell thickness, particle size, and filling amount of the aerosol generating capsule 104, heating efficiency, external dimensions, and single-use duration can be taken into account simultaneously, thereby optimizing the performance of the aerosol generating system and improving the user experience.

[0059] The aerosol generating capsule 104 used in this embodiment of the invention can be prepared by a variety of methods, such as one of the following methods.

[0060] Heat 40 parts by weight of sunflower seed oil to 100°C, and while stirring, add 7.1 parts by weight of ethyl cellulose, 1.4 parts by weight of beeswax, and 2.1 parts by weight of palm wax. Dissolve and mix evenly, cool to 60°C, and add 24 parts by weight of propylene glycol, 16 parts by weight of glycerol, 2.4 parts by weight of surfactant (prepared from Tween 80 and glyceryl monooleate in a weight ratio of 1:9), 5 parts by weight of mango flavoring, and 2 parts by weight of nicotine salt. Stir evenly to complete the preparation of the core material.

[0061] Add 5 parts by weight of carrageenan and 3 parts by weight of gellan gum to 82 parts by weight of purified water, and heat while stirring at a temperature of 60-90°C to form a homogeneous solution. Add 10 parts by weight of glycerol and stir until homogeneous to prepare the film solution.

[0062] Using a concentric dropper, the core material (inner layer) and film liquid are dripped into the cooling liquid (MCT) while the temperature is controlled at 10℃~25℃ to form wet capsules. The capsules are then stored at -10℃~10℃ for 10 hours and dried at 20~30℃ and 20%~50% humidity to obtain capsule products with a particle size of 2mm and a wall thickness of 70μm.

[0063] In some embodiments, reference Figure 2 The thickness of the sensor 107 is between 10 and 100 μm. Specifically, it can be, for example, 10 μm, 25 μm, 50 μm, 75 μm, 100 μm, etc.

[0064] In practical applications, the thickness of the receptor 107 can be determined based on the specific circumstances. The thickness of the receptor 107 affects its heating efficiency and response time. For example, if the thickness is too thin, the receptor 107 may not be able to effectively generate enough heat to continuously heat the aerosol-forming capsule 104; while if the thickness of the receptor 107 is too thick, although it may improve the heat storage capacity, it will also lead to a slower heating rate and a longer response time.

[0065] In some embodiments, the sensor 107 is located at the radial center of the aerosol generating matrix segment 101 and extends axially. This helps to ensure that the heat generated by the sensor 107 is uniformly transferred to the surrounding aerosol generating capsule 104, thereby achieving uniform heating.

[0066] Furthermore, the sensor 107 extends along the axial direction of the aerosol generation matrix segment 101, which ensures that the entire matrix segment 101 can be effectively heated.

[0067] In some embodiments, the receptor 107 may be sheet-like, hollow cylindrical, or impeller-like.

[0068] In a specific implementation plan, refer to Figure 2 In the first illustration, the cross-sectional shape of the receptor 107 can be in the shape of a "I". Therefore, the structure of the receptor 107 is simpler, easier to manufacture, and can be adapted to and accommodated in aerosol generating matrix segments 101 of different sizes.

[0069] In a specific implementation plan, refer to Figure 2 In the second illustration, the cross-sectional shape of the receptor 107 can be "S" shaped, that is, the sheet-like receptor 107 is bent and extended. As a result, the heat transfer area of ​​the receptor 107 is significantly increased, further improving the uniformity and efficiency of heating the aerosol generating capsule 104.

[0070] In a specific implementation plan, refer to Figure 2In the third illustration, the cross-sectional shape of the sensor 107 can be V-shaped, meaning the sheet-like sensor 107 is bent in a plane perpendicular to the extension direction, and the angle of the V-shape can be adjusted according to actual needs. This increases the heat transfer area of ​​the sensor 107 while simplifying the manufacturing process. For example, it can be formed through simple bending. Figure 2 The third type of "V"-shaped receptor 107 is shown in the diagram.

[0071] In a specific implementation plan, refer to Figure 2 In the fourth illustration, the cross-sectional shape of the receptor 107 can also be radial, also known as impeller-shaped. That is, the receptor 107 can include multiple extension plates, with one side of each extension plate connected together and the sides relatively separated from each other. For example, the cross-sectional shape of the receptor 107 can be a cross shape, an asterisk shape, etc. The number of extension plates is no less than three. This further increases the heat transfer area of ​​the receptor 107, and also allows for a more rational division of the internal space of the aerosol generation matrix section 101, resulting in a more reasonable arrangement of the aerosol generation capsules 104. This also helps to improve heat transfer efficiency, increase the porosity of the aerosol generation capsules, and thus reduce suction resistance.

[0072] In some embodiments, the sensor 107 comprises a metallic material. Thus, in the aerosol generating article 10, the sensor 107 comprising a metallic material serves as a heating element, effectively converting electromagnetic energy into thermal energy and transferring the heat to the aerosol generating capsule 104, thereby generating an aerosol.

[0073] In a preferred embodiment, the metal material is stainless steel. This ensures that the receptor 107 maintains stable performance within the aerosol-generating article 10.

[0074] In some embodiments, the sensor 107 comprises a non-metallic material and a metallic material layer in contact with the non-metallic material. The non-metallic material is primarily used to provide protection for the metallic material.

[0075] refer to Figure 3 This application also provides an aerosol generation system, including the aforementioned Figures 1 to 2 The aerosol generating article 10 and the electromagnetic heating device QE for heating the aerosol generating article 10, wherein the aerosol generating matrix segment 101 of the aerosol generating article 10 is inserted into the electromagnetic heating device QE, and the electromagnetic heating device QE generates a fluctuating electromagnetic field acting on the sensor 107 inside the aerosol generating matrix segment 101, causing the sensor to heat up and heating the aerosol generating capsule 104 through heat transfer.

[0076] Specifically, the electromagnetic heating device QE can be designed using existing technology, generally including an electromagnetic heating cavity QE1 and a power supply and control module QE2. The electromagnetic heating cavity QE1 has a built-in electromagnetic field generating coil for generating a undulating electromagnetic field, and the electromagnetic heating cavity has a heating hole for receiving the aerosol-generated product 10.

[0077] In some embodiments, the aperture and depth of the heating hole may be adapted to the aerosol generating matrix segment 101. When the aerosol generating article 10 is heated, the aerosol generating matrix segment 101 of the aerosol generating article 10 can be inserted into the heating hole and heated.

[0078] In some embodiments, the sections of the aerosol generating article 10 other than the aerosol generating matrix section 101 are located outside the heating holes, thereby preventing the materials in other sections from being heated and generating unintended harmful substances or unpleasant odors that could affect the user's health and experience.

[0079] In some embodiments, the heating power of the electromagnetic heating device QE is 1 to 8 W. This ensures that the aerosol generating capsule 104 is rapidly heated and ruptured, thus meeting user needs promptly.

[0080] In some embodiments, the frequency of the undulating electromagnetic field is between 1 MHz and 30 MHz. This ensures both the heating efficiency of the electromagnetic heating device QE, thereby increasing the aerosol generation rate and shortening the preheating time, and also guarantees the safety of the electromagnetic heating device QE during use.
