Description

Technical Field

[0001] This application belongs to the field of aerosol heating technology, specifically relating to an aerosol generating device, a temperature measurement method for the aerosol generating device, and a storage medium. Background Technology

[0002] Electromagnetic heating technology offers advantages such as rapid heating, high thermal efficiency, and no need for cleaning of smoking appliances. It utilizes the principle of high-frequency electric heating, converting alternating current into high-frequency current to generate a high-frequency magnetic field. When the magnetic field lines act on the heating element, they are cut, generating numerous small eddy currents that rapidly heat the heating element, thus achieving the heating purpose. Compared to traditional resistance heating, electromagnetic heating addresses several consumer pain points, such as uneven heating, difficulty in cleaning, and the susceptibility of the sheet-like heating element to breakage inherent in resistance heating.

[0003] Resistance heating technology is an earlier and more mature field, with related patents already filed by companies such as Philip Morris International, creating high patent barriers that are difficult for newcomers to overcome. Electromagnetic heating technology, on the other hand, is a newer field with relatively fewer patents, providing more room for development for other companies and helping to create differentiated competition in the new tobacco market.

[0004] Consumers are increasingly demanding higher quality from heated cigarette products, hoping for a taste and smoking experience closer to traditional cigarettes, as well as a more stable and uniform heating effect. Electromagnetic heating technology, through optimized design, such as the use of dynamic frequency control and closed-loop temperature control systems, can better meet consumers' requirements for heating effect and quality.

[0005] In the emerging tobacco industry, technological innovation is a key driver of development. High-frequency heating, as a promising heating method, has attracted significant attention and R&D investment from numerous companies. For example, Philip Morris International's IQOS Iluma abandons traditional resistance heating elements and adopts electromagnetic induction technology; British American Tobacco's Glo, Japan Tobacco's Ploom, and Anhui Tobacco's Tooop-zero have also adopted electromagnetic heating technology, promoting the continuous development and progress of electromagnetic heating tobacco products.

[0006] The electromagnetic field generated by this type of electromagnetic heating appliance affects the temperature sensing element in several ways: The element is exposed to a high-frequency electromagnetic field, which can influence its electrical properties. For example, the thermocouple's thermoelectric potential may deviate due to electromagnetic induction, leading to inaccurate temperature readings. Furthermore, the element itself generates heat under the influence of the high-frequency electromagnetic field, increasing its temperature and affecting measurement accuracy. In addition, the element can alter the distribution of the electromagnetic field, causing electromagnetic field lines to accumulate at the element's location, potentially leading to electrical breakdown. This not only affects heating uniformity but also compromises the safety of the circuit board. Summary of the Invention

[0007] In view of this, the purpose of this application is to provide an aerosol generating device, a temperature measurement method thereon, and a storage medium thereon to solve the above problems.

[0008] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0009] In a first aspect, this application provides an aerosol generating apparatus, which includes a heating chamber, a heating component, an LC temperature measuring component, and a control component. The heating component heats an aerosol forming matrix contained within the heating chamber during operation to generate aerosols. The LC temperature measuring component measures the heating temperature of the heating component. The control component controls the heating component based on the heating temperature. The LC temperature measuring component includes a main temperature measuring element and a reference temperature measuring element. The main temperature measuring element is wound around the outer wall surface of the heating chamber and arranged coplanarly with the heating component, and is used to measure first temperature-related information of the heating component. The reference temperature measuring element is disposed at the bottom of the heating chamber and forms a nested structure with the main temperature measuring element, and is used to measure second temperature-related information of the ambient temperature. The control component determines the target temperature of the heating component based on the first and second temperature-related information.

[0010] Furthermore, the heating component is an electromagnetic heating component, which is used to generate a changing magnetic field to heat the aerosol formation matrix.

[0011] Furthermore, a heat insulation layer is provided at the bottom of the heating chamber, which separates the main temperature measuring element from the reference temperature measuring element.

[0012] Furthermore, the main temperature measuring element is an LC circuit made of temperature-sensitive magnetic core material, and the reference temperature measuring element is an LC circuit packaged with non-temperature-sensitive material. The main temperature measuring element and the reference temperature measuring element form a parallel resonance.

[0013] Secondly, this application provides a temperature measurement method for an aerosol generating device, applied to the aerosol generating device of the first aspect above. The temperature measurement method includes: step S1: the control component acquires the main resonant frequency of the main temperature measuring element, the reference resonant frequency of the reference temperature measuring element, and the heating temperature of the heating component; step S2: the control component establishes a temperature-frequency model based on the main resonant frequency, the reference resonant frequency, and the heating temperature; step S3: according to the temperature-frequency model, the main resonant frequency and the reference resonant frequency are converted and processed to obtain the target temperature of the heating component.

[0014] Furthermore, the reference resonant frequency is calculated using the following formula:

[0015]

[0016] Where f1 is the reference resonant frequency, L1 is the inductance of the reference temperature sensor, and C1 is the capacitance of the reference temperature sensor.

[0017] Furthermore, the principal resonant frequency is calculated using the following formula:

[0018]

[0019] Where f2 is the main resonant frequency, L2(T) is the inductance of the main temperature measuring element at temperature T, C2 is the capacitance of the main temperature measuring element, and T is the target temperature of the heating component.

[0020] L2(T)=L0(T)(1+αT)

[0021] Where L0(T) represents the inductance value under the initial temperature conditions, and α is the inductance temperature coefficient of the main temperature measuring element.

[0022] Furthermore, step S2 includes: step S21: the control component obtains the resonant frequency difference based on the main resonant frequency and the reference resonant frequency; step S22: the resonant frequency difference and temperature are fitted based on the least squares method to obtain a temperature-frequency model.

[0023] Furthermore, the temperature-frequency model is calculated using the following formula:

[0024]

[0025] Where T is temperature, Δf is the resonant frequency difference, b is the intercept, and k is the sensitivity coefficient.

[0026] Thirdly, this application provides a computer-readable storage medium having a computer program / instructions stored thereon, which, when executed by a processor, implements the steps of the temperature measurement method of the first aspect.

[0027] Among them, aerosol-generating products are smoking products, including aerosol-forming matrix, which generates aerosols through heating that can be directly inhaled into the lungs of the user through the user's mouth.

[0028] Preferably, the aerosol forming matrix is ​​a solid aerosol forming matrix. The aerosol forming matrix may include both solid and liquid components.

[0029] Preferably, the aerosol-forming matrix includes nicotine. In some preferred embodiments, the aerosol-forming matrix includes tobacco.

[0030] 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 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 may be a fixator for a smoking article.

[0031] A sensor is a material that can convert electromagnetic energy into heat. When placed in a undulating electromagnetic field, the eddy currents induced in the sensor cause it to heat up. When an elongated sensor is positioned in thermal contact with an aerosol-forming matrix, the aerosol-forming matrix is ​​heated by the sensor.

[0032] 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 a sensor located within the fluctuating electromagnetic field. In use, the aerosol generating article engages with the aerosol generating device such that the sensor is located within the fluctuating electromagnetic field generated by the sensor.

[0033] The length of the receptor is greater than its width or thickness, for example, more than twice its width or thickness. Therefore, the receptor can be described as an elongated receptor. The receptor can be arranged generally longitudinally within the aerosol-generating matrix. This means that the length of the elongated receptor is arranged approximately parallel to the longitudinal direction of the aerosol-generating matrix, for example, within plus or minus 10 degrees. In a preferred embodiment, the elongated receptor can be located at a radial center position within the aerosol-generating matrix and extend along the longitudinal axis of the aerosol-generating matrix.

[0034] The sensor can be made of any material capable of being heated inductively to a temperature sufficient to generate an aerosol matrix. Preferred sensors include metals or carbon. Preferred sensors may include ferromagnetic materials, such as ferrite, ferromagnetic steel, or stainless steel. Suitable sensors may be aluminum or may include aluminum. Preferred sensors 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 sensor, such as material type, length, width, and thickness, can be varied within a known electromagnetic field to provide the desired energy consumption.

[0035] The receptors are arranged in thermal contact with the aerosol-forming matrix. Therefore, when the receptors are heated, the aerosol-forming matrix is ​​heated and forms an aerosol. In one embodiment, a heating element including the receptors is inserted into the aerosol-forming matrix, and the aerosol-generating apparatus may include one or more elongated heating elements. In another embodiment, the aerosol-generating matrix may include the receptors; alternatively, the aerosol-generating matrix may include multiple receptors, and the receptors may be elongated, granular, mesh-like, radial, tubular, hourglass-shaped, spiral, etc.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] As can be seen from the above technical solutions, the advantages and positive effects of the aerosol generating device, its temperature measurement method, and its storage medium proposed in this application are as follows:

[0043] The main temperature sensing element is directly wound onto the outer wall surface of the heating cavity and arranged coplanarly with the heating coil to achieve maximum electromagnetic coupling efficiency. Changes in inductance directly reflect temperature fluctuations within the cavity. The reference temperature sensing element is placed at the bottom of the heating cavity, forming a concentric nested structure with the main temperature sensing element. Physical isolation eliminates magnetic field interference in the heating zone, allowing only the ambient temperature reference signal to be collected. Based on the LC resonance principle, the main and reference temperature sensing elements adopt a parallel resonance mode. By comparing their frequency differences, common-mode interference such as ambient noise and power fluctuations is canceled out. The coordinated operation of the two LC temperature sensing components improves temperature measurement accuracy and anti-interference capability. Attached Figure Description

[0064] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0065] Please refer to Figure 1 This application provides an aerosol generating device, which includes a heating chamber, a heating component 11, an LC temperature measuring component, and a control component.

[0066] The heating component 11 is used to heat the aerosol forming matrix 20 contained in the heating chamber during operation to generate aerosols. The LC temperature measuring component measures the heating temperature of the heating component 11, and the control component controls the heating component 11 according to the heating temperature.

[0067] For example, the heating component 11 can be an electromagnetic heating component 11, such as an electromagnetic heating coil, which is used to form a changing magnetic field to heat the aerosol forming matrix 20.

[0068] The LC temperature measurement assembly includes: a main temperature measuring element 12 and a reference temperature measuring element 13.

[0069] The main temperature measuring element 12 is wound around the outer wall surface of the heating chamber and arranged coplanarly with the heating assembly 11, and is used to measure the first temperature-related information of the heating assembly 11.

[0070] The main LC circuit of the main temperature measuring element 12 uses a toroidal inductor made of temperature-sensitive magnetic core material (permalloy), which is directly wound on the outer wall surface of the heating cavity and arranged coplanarly with the heating coil to achieve maximum electromagnetic coupling efficiency. The change in inductance value directly reflects the temperature fluctuation of the heating cavity.

[0071] The reference temperature measuring element 13 is located at the bottom of the heating chamber and forms a nested structure with the main temperature measuring element 12. It is used to measure the second temperature correlation information of the ambient temperature information.

[0072] A heat insulation layer 14 is also provided at the bottom of the heating chamber, which separates the main temperature measuring element 12 and the reference temperature measuring element 13.

[0073] A heat insulation layer 14 is placed between the main temperature measuring element 12 and the reference temperature measuring element 13. The heat insulation layer 14 is made of heat insulation gel to prevent the heat from the heating chamber from affecting the reference temperature measuring element 13.

[0074] Specifically, the reference LC circuit of the reference temperature sensing element 13 is encapsulated with a non-temperature-sensitive material (PEEK insulation layer 14) and placed in the constant temperature zone at the bottom of the heating chamber, forming a concentric nested structure with the main circuit. Physical isolation eliminates magnetic field interference in the heating zone, and only the ambient temperature reference signal is collected.

[0075] Understandably, based on the LC resonance principle, the main circuit and the reference circuit adopt a parallel resonance mode. By comparing the frequency difference between the two circuits, common-mode interference such as environmental noise and power fluctuations is canceled out. The coordinated work of the two LC circuits improves the temperature measurement accuracy and anti-interference capability.

[0076] The temperature sensing inductor L2 of the main LC circuit of the main temperature sensing element 12 is made of a toroidal inductor with a temperature-sensitive magnetic core material (permalloy), and is directly wound on the outer wall surface of the heating cavity below the heating coil. The inductor L1 of the reference LC circuit of the reference temperature sensing element 13 is located below the temperature sensing inductor L2, and is encapsulated with a non-temperature-sensitive material (PEEK insulation layer 14), and placed in the constant temperature zone at the bottom of the heating cavity, forming a concentric nested structure with the main LC circuit.

[0077] Understandably, based on the LC resonance principle, the main circuit and the reference circuit adopt a parallel resonance mode. By comparing the frequency difference between the two circuits, common-mode interference such as environmental noise and power fluctuations is canceled out. The coordinated work of the two LC circuits improves the temperature measurement accuracy and anti-interference capability.

[0078] The control component determines the target temperature of the heating component 11 based on the first temperature association information and the second temperature association information.

[0079] Please refer to Figure 2 Based on the same inventive concept, this application also provides a temperature measurement method for an aerosol generating device, the specific steps of which are as follows:

[0080] Step S1: The control component acquires the main resonant frequency of the main temperature measuring element 12, the reference resonant frequency of the reference temperature measuring element 13, and the heating temperature of the heating component 11.

[0081] The reference temperature measuring element 13 is equipped with an LC circuit 1, and the reference resonant frequency of the LC circuit 1 is calculated according to the following formula:

[0082]

[0083] Where f1 is the reference resonant frequency, L1 is the inductance of the reference temperature measuring element 13, and C1 is the capacitance of the reference temperature measuring element 13.

[0084] The main temperature measuring element 12 is equipped with an LC circuit 2, which constitutes a measuring circuit and consists of an inductor L2 and a capacitor C2.

[0085] The temperature change relationship is as follows:

[0086] L2(T)=L0(T)(1+αT)

[0087] Where L0(T) represents the inductance value under the initial temperature conditions, that is, the initial inductance value of inductor L2 measured before heating starts, and the temperature coefficient of inductor L2 is α, in units of (H / ℃).

[0088] Its main resonant frequency is calculated using the following formula:

[0089]

[0090] Where f2 is the main resonant frequency, L2(T) is the inductance of the main temperature measuring element 12 at temperature T, C2 is the capacitance of the main temperature measuring element 12, and T is the target temperature of the heating component 11.

[0091] The main resonant frequency and the reference resonant frequency can be acquired by using the timer module of a microcontroller or a dedicated frequency counter to acquire the oscillation frequencies of the two circuits.

[0092] Step S2: The control component establishes a temperature-frequency model based on the main resonant frequency, the reference resonant frequency, and the heating temperature.

[0093] Specifically, a functional correspondence between temperature and frequency is established by placing the dual LC circuit at different temperatures (e.g., 0℃ to 300℃) and recording the corresponding frequency difference Δf = f2 - f1.

[0094] The relationship between Δf and temperature T is fitted using the least squares method.

[0095] For example: the model is fitted as a linear model Δf = kT + b.

[0096] Where k is the sensitivity coefficient (Hz / ℃) and b is the intercept.

[0097] By acquiring f1 and f2 in real time, Δf is calculated and converted into a temperature value through a calibration model.

[0098]

[0099] Where T is temperature, Δf is the resonant frequency difference, b is the intercept, and k is the sensitivity coefficient.

[0100] Step S3: Based on the temperature-frequency model, convert the main resonant frequency and the reference resonant frequency to obtain the target temperature of the heating component 11.

[0101] It is understandable that, referring to the relevant literature "Research on an LC Resonant Wireless Passive Temperature Sensor", the impedance characteristics of the sensor at different temperatures show that the resonant frequency shifts towards lower frequencies and decreases almost linearly with increasing temperature. Using linear fitting, the relationship between the resonant frequency and temperature can be obtained as: f(MHz) = 1.24 - 0.0023T. For every degree Celsius increase in temperature, the sensor's resonant frequency decreases by approximately 2.3 kHz.
