Description

Heating non-combustible device and its heating control method Technical Field

[0001] This invention relates to the field of atomization, and more particularly to a heating non-combustible device and its heating control method. Background Technology

[0002] Due to the complexity of the effective components in aerosol-forming matrix (ACM), it is difficult to accurately measure the internal temperature of the ACM during actual heating in heated non-combustible devices. Most methods rely on measuring the temperature of the heat source or other surfaces, hoping to deduce the internal temperature of the ACM from these readings. However, due to user preferences, the complexity of the atomization process, and the lag in heating feedback, it is difficult to establish an accurate heat and mass transfer model based on temperature. In practical applications, it is even more difficult to precisely control the atomization process of the ACM using temperature alone. Summary of the Invention

[0062] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0063] First, it's important to clarify that during the actual heating process of the heated non-combustible device, temperature is a scalar quantity of energy, and all energy originates from battery power. Without battery power, the aerosol forming matrix cannot be heated and atomized, nor can there be any significant temperature change. Based on this principle, precise control of the energy supply also allows for precise control of the atomization of the aerosol forming matrix. Temperature serves merely as a benchmark to monitor for any abnormal conditions (such as excessively high or low temperatures) caused by uncontrolled energy supply.

[0064] Based on this, the correlation between atomization and power heating control can be analyzed using the energy transfer model of heating and the relationship model between atomization and energy, and a suitable power control scheme can be designed. During actual power heating, a suitable power is output by combining the suction duration and suction interval, i.e., adaptively adjusting the energy supply to the aerosol-forming matrix.

[0065] According to the drying kinetics-infrared radiation heating unsteady-state drying rate equation, the atomization rate of the aerosol-forming matrix depends on: the temperature of the heating element, the temperature of the aerosol-forming matrix, the temperature difference between the heating element and the aerosol-forming matrix, and the temperature rise rate. Furthermore, when radiation accounts for a large proportion, it is proportional to the fourth power of the temperature; when heat transfer accounts for a large proportion, it is proportional to the first power of the temperature.

[0066] The following analysis uses the radiative heat transfer model of an infrared atomizer at the center of the light wave as an example:

[0067] Assume a cylindrical infrared radiation source is surrounded by a quartz tube, and an aerosol-forming matrix completely encapsulates the quartz tube. The temperature of the infrared radiation source is Ts, and the radiative heat transfer rate (W / m²) is q. rad The convective heat transfer rate (W / m2) is q conv Heat conduction is expressed as the heat transfer rate (W / m²) q con The temperature of the quartz tube can be measured by a thermocouple or a temperature-sensing membrane, for example, as Tsur, and Tsur ≠ Ts.

[0068] Assumptions: The absorptivity of the infrared element surface is equal to its emissivity, i.e., a = ɛ, and the radiative heat transfer rate is q. rad Possible forms:

[0069] Formula 1

[0070] Where ɛ is the infrared emissivity of the surface, and σ is the Stephen-Boltzmann constant. Ts is the temperature of the infrared radiation source, K; Tsur is the temperature of the quartz tube surrounding the infrared radiation source, K. Equation 1 gives the difference between the heat energy released by the surface due to its own radiation and the heat energy gained from absorbing radiation.

[0071] Simultaneously, heat can be transferred to the adjacent gas via convection and to the quartz tube via conduction (heat transfer from the quartz tube to the cigarette burner). In this case, the total outward heat transfer rate from the surface is as follows:

[0072] Formula 2

[0073] Where A is the surface area, m 2 h is the convective heat transfer coefficient, in W / (m²). 2 ▪K 4 K is the thermal conductivity of the quartz tube carrier, W / (m²). 2 ▪℃), ф is the thermal conductivity area of ​​the quartz tube carrier, in m². 2 ΔT represents the temperature difference between the infrared radiation source and the quartz tube, in Kelvin. Since the effect of temperature on the convective heat transfer coefficient h is generally weak in this model, and Ts and T∞ are not significantly different, the effect of qconv can be ignored when calculating the sum of heat transfer rates. Equation 2 can be simplified to:

[0074] Formula 3

[0075] As can be seen from the above formulas, thermal radiation is proportional to the fourth power of temperature, and thermal conduction is proportional to the first power of the temperature change.

[0076] The factors affecting energy supply are the power amplitude, duty cycle, and frequency. With the frequency remaining constant, energy can be regulated by adjusting the power amplitude and duty cycle. Furthermore, different amplitudes and duty cycles affect the proportions of heat radiation and heat conduction.

[0077] Figure 1 is a flowchart of a first embodiment of the heating control method of the heating non-combustible device of the present invention. The heating control method of this embodiment is applied to the control component of the heating non-combustible device. The heating non-combustible device also includes a heating component, a battery component, a temperature detection component, etc., wherein the battery component provides power to the heating component; the heating component is used to heat the aerosol forming matrix, and the heating component can be an infrared heating component, a microwave heating component, an electromagnetic heating component, or a resistance heating component.

[0078] As shown in Figure 1, the heating control method of this embodiment includes:

[0079] Action judgment step S10: Acquire the user's suction information in real time, and determine whether a suction action has occurred based on the suction information;

[0080] Regarding this step, in some embodiments, the user's suction information can be directly acquired by setting an airflow sensor. In other embodiments, since the increase in airflow during user suction causes a decrease in the temperature of the heating component, the user's suction information can be indirectly acquired by detecting the temperature information of the heating component in real time. The suction action refers to the user directly inhaling the aerosol-generated product through their mouth. Through the user's suction, a certain amount of airflow flows from the aerosol-generated product to the user's mouth. Alternatively, the user inhales through their mouth to the nozzle of the aerosol-generating device, and through the user's suction, a certain amount of airflow flows from the nozzle to the user's mouth. The suction action can be detected directly by an airflow sensor or indirectly by whether the temperature change of the heating element (the value of the temperature drop within a preset time) exceeds a threshold.

[0081] Feature acquisition step S20: When a suction action occurs, the current suction features are acquired by processing the suction information;

[0082] Energy determination step S30: Determine the supply energy information for the current pumping based on the current pumping characteristics;

[0083] Energy output step S40: Output energy according to the supplied energy information.

[0084] In this embodiment, the system determines whether a suction action has occurred by real-time monitoring of the user's suction information. If a suction action occurs, the system further analyzes the current suction characteristics based on the suction information, determines the energy supply information based on these characteristics, and then outputs the energy. In this control process, because the energy supply to the aerosol forming matrix can be precisely controlled based on the user's suction characteristics (related to preferences and habits), the atomization process of the aerosol forming matrix can be precisely controlled without considering the complexity of the atomization process or the lag in heating feedback.

[0085] In one specific embodiment, the suction characteristics include, for example, the number of suction ports, suction depth, suction duration, and the interval between suction ports and the previous suction port. Furthermore, the current suction characteristics can be determined as follows: For the current number of suction ports, the current number of suction ports can be updated each time a suction action is detected. For example, if the initial number of suction ports is 0, the number of suction ports is incremented by 1 each time a suction action is detected. For the current suction depth, the current suction depth can be determined based on the change in temperature between the current temperature and the temperature before a preset time period; a larger rate of change indicates a larger suction depth, and vice versa. For the suction duration of the current number of suction ports, the moment the heating start signal is received can be used as the start time, and the suction duration of the current number of suction ports can be determined by calculating the time between the current moment and the start time. For the interval between the current suction port and the previous suction port, the time of the end of each suction port can be recorded, and the interval between the current suction port and the previous suction port can be determined by calculating the difference between the end times of two adjacent suction ports.

[0086] Further, in an optional embodiment, the current suction characteristics include: the current number of suction ports. Moreover, the energy determination step S30 includes:

[0087] Step S31: Obtain the basic power curve, and determine the basic energy information corresponding to the current number of suction ports based on the current suction characteristics and the basic power curve, wherein the basic power curve is the relationship curve between power and suction characteristics;

[0088] Step S32: Obtain the pre-stored first energy table, and determine the compensation energy information corresponding to the current number of suction ports based on the current suction characteristics and the first energy table. The first energy table includes the compensation energy information corresponding to different suction characteristics under good taste obtained through testing.

[0089] Step S33: Determine the supply energy information corresponding to the current number of suction ports based on the basic energy information and the compensation energy information.

[0090] In this embodiment, after obtaining the current pumping characteristics, the supply energy information can be determined by combining the base power curve and the first energy table. This method is simple to calculate and consumes fewer resources. Of course, in other embodiments, after obtaining the current pumping characteristics, the supply energy information of the current pumping can also be obtained through model analysis. For example, this specifically includes: obtaining a pre-stored energy model and inputting the current pumping characteristics into the energy model to obtain the supply energy information of the current pumping.

[0091] Furthermore, in an optional embodiment, the current suction characteristics further include: the suction duration of the current suction stroke, and the interval between the current suction stroke and the previous suction stroke. Moreover, step S31 includes:

[0092] Based on the basic power curve, the suction duration of the current suction port, and the interval between the current suction and the previous suction, the basic energy information corresponding to the current suction port is determined, wherein the basic power curve is a curve of power changing with time.

[0093] In one specific embodiment, the basic energy information can be determined as follows: Since the basic power curve is a curve of power changing with time, the basic energy information corresponding to the current number of suction ports can be obtained by integrating the power value in the corresponding time period on the basic power curve based on the suction duration of the current number of suction ports and the interval between the current suction and the previous suction.

[0094] Furthermore, in an optional embodiment, the current aspiration feature further includes: the current aspiration depth. Moreover, step S32 includes:

[0095] The compensation energy information corresponding to the current number of puffs is determined based on the first energy table, the current number of puffs, the current puff depth, and the interval between the current puff and the previous puff. The first energy table includes the compensation energy information corresponding to each number of puffs under good taste conditions at different intervals from the previous puff, obtained through testing.

[0096] In one specific embodiment, the compensation energy information can be determined as follows: Since the first energy table (the energy table corresponding to good taste) includes the compensation energy information corresponding to each number of puffs under good taste at different intervals from the previous puff, that is, the first energy table is a two-dimensional table, the corresponding energy value can be determined by looking up the table based on the current number of puffs and the interval between the current puff and the previous puff. Then, the energy value determined by looking up the table is adjusted according to the current puff depth, and the adjusted energy value is used as the compensation energy.

[0097] In another specific embodiment, the compensation energy information can be determined in the following way: the first energy table is configured to include the compensation energy information corresponding to each number of sucking holes under good taste at different sucking depths and at different intervals from the previous sucking. That is, the first energy table is a three-dimensional table. In this way, the corresponding compensation energy information can be determined directly by looking up the table based on the current number of sucking holes, the current sucking depth, and the interval between the current sucking and the previous sucking.

[0098] Furthermore, in an optional embodiment, a second energy meter is pre-stored, and step S33 includes:

[0099] The basic energy information is added to the compensation energy information to obtain the first total energy information;

[0100] Based on the pre-stored second energy table, determine the second total energy information corresponding to the current sucking feature, and determine whether the first total energy information falls within the numerical range of the second total energy information. The second energy table includes the total energy information corresponding to different sucking features under poor taste obtained through testing, such as the total energy information corresponding to multiple sucking durations under poor taste.

[0101] If it does not fall into the pool, the first total energy information will be used as the supply energy information corresponding to the current number of suction ports;

[0102] If the value falls within the range of the second total energy information, the first total energy information is adjusted so that the adjusted first total energy information does not fall within the range of the second total energy information, and the adjusted first total energy information is output.

[0103] In this embodiment, the basic energy information and the compensation energy information are first added together to obtain the first total energy information. At this time, the first total energy information is not directly used as the supply energy information. Instead, it is first determined whether the first total energy information falls within the corresponding energy range of the second energy table corresponding to poor taste. If so, in order to avoid the user obtaining poor taste, the first total energy information can be adjusted (for example, increased or decreased) so that the adjusted first total energy information does not fall within the numerical range of the second total energy information. Then, the adjusted first total energy information is output.

[0104] Further, in an optional embodiment, the energy output step S40 includes:

[0105] Step S41: In the i-th adjustment period, determine the current power and output the current power, wherein the interval duration is longer than the adjustment period, and the current power is negatively correlated with i, i=1, 2, 3, ...;

[0106] Step S42: Calculate the output energy corresponding to the current number of suction ports based on the current power.

[0107] Step S43: Determine whether the supplied energy information is consistent with the current output energy. If not, proceed to the next adjustment cycle and execute step S41.

[0108] Regarding this embodiment, it should be noted that different users' suction habits will lead to different suction intervals, generally ranging from 5 to 30 seconds. Therefore, the adjustment cycle can be set to 1 second or 2 seconds. Thus, taking 1 second as an example, one interval can include 5 to 30 adjustment cycles. Moreover, the power of each adjustment cycle is negatively correlated with i, that is, the power decreases as the adjustment cycle increases (high power first, then low power). For example, the power of the first adjustment cycle is 3W, the power of the second adjustment cycle is 2.8W, the power of the third adjustment cycle is 2W, and so on, until the output energy equals the supply energy.

[0109] Further, in an optional embodiment, obtaining the base power curve includes:

[0110] Obtain a pre-stored reference power curve, wherein the reference power curve is a curve of power changing over time at a specific ambient temperature;

[0111] Obtain the current ambient temperature and determine the current environmental change coefficient corresponding to the current ambient temperature;

[0112] The baseline power curve is corrected based on the current environmental change coefficient to obtain a basic power curve, which is the curve of power changing over time at the current ambient temperature.

[0113] In this embodiment, since different users may use this type of heated non-combustible device at different ambient temperatures, and different ambient temperatures affect the atomization effect of the aerosol-forming matrix, a reference power curve can be pre-stored in the heated non-combustible device. This reference power curve is a curve showing the change in power with suction time at a specific ambient temperature (e.g., 10 degrees Celsius). When the user uses the device, the current ambient temperature can be obtained. For example, temperature information can be detected by setting temperature sensing components on the battery and charging chip, and the current ambient temperature can be determined by fusing the detected temperature information from both. After determining the current ambient temperature, a corresponding environmental change coefficient is determined based on this ambient temperature. For example, in one implementation, multiple environmental change coefficients corresponding to different ambient temperatures can be pre-stored in the heated non-combustible device. After determining the current ambient temperature, the current environmental change coefficient can be obtained by looking up a table. In another implementation, a function for the environmental change coefficient can be pre-stored in the heated non-combustible device. After determining the current ambient temperature, the function can be substituted to calculate the current environmental change coefficient. Finally, after obtaining the current environmental change coefficient, the reference power curve at a specific ambient temperature is corrected based on this coefficient to obtain the base power curve at the current ambient temperature.

[0114] Furthermore, in an optional embodiment, the reference power curve is obtained in the following manner:

[0115] Step S51: During the process of multiple testers using N1 test prototypes to conduct suction tests in a standard suction method, the first power curve is adjusted by receiving the power adjusted in real time by the testers to obtain a good taste, so as to obtain N1 adjusted second power curves; wherein, the initial first power curve is pre-stored in the N1 test prototypes, and N1 is a natural number greater than 1.

[0116] Step S52: Perform fusion processing on the N1 second power curves to obtain the optimal power curve;

[0117] Step S53: Store the optimal power curve in N2 test samples, where N2 is a natural number greater than 1 and N2 is greater than N1;

[0118] Step S54: During the process of multiple testers using N2 test samples to conduct suction tests in multiple different ambient temperatures according to the standard suction method, the taste evaluation type of each suction port is obtained by the testers, and the real-time output power and temperature information of the heating component are recorded. The taste evaluation type includes good taste, poor taste, and may further include general taste.

[0119] Step S55: Based on the taste evaluation type of each suction port, the ambient temperature, and the real-time output power, obtain the total energy information corresponding to each taste evaluation type at each ambient temperature and the energy information corresponding to each suction port.

[0120] Step S56: Based on the total energy information corresponding to the good taste evaluation type under different ambient temperatures and the energy information of each pump, determine the baseline power curve and the environmental variation coefficient corresponding to multiple different ambient temperatures.

[0121] Furthermore, to improve the accuracy of the optimal power curve, step S52 may specifically include:

[0122] Step S521: Merge the N1 second power curves to obtain the third power curve;

[0123] Step S522: Store the optimal power curve in N3 test samples, where N3 is a natural number greater than 1;

[0124] Step S523: During the process of multiple testers using N3 test samples to conduct suction tests in multiple different ambient temperatures according to the standard suction method, the third power curve is adjusted by receiving the power adjusted in real time by the testers in order to obtain a good taste, so as to obtain N3 adjusted fourth power curves.

[0125] Step S524: The N3 fourth power curves are fused to obtain the optimal power curve.

[0126] Further, the first energy table is obtained in the following manner:

[0127] Step S61: Store the reference power curve and multiple environmental variation coefficients into N4 test prototypes, where N4 is a natural number greater than 1;

[0128] Step S62: Obtain the current ambient temperature, determine the current ambient change coefficient corresponding to the current ambient temperature, and correct the reference power curve according to the current ambient change coefficient to obtain the current base power curve.

[0129] Step S63: During the process of multiple testers using N4 test samples to conduct suction tests in a random suction manner, obtain the taste evaluation type of each suction port from the testers, and record the real-time output power and temperature information of the heating component.

[0130] Step S64: The recorded temperature information is processed to obtain the current suction characteristics, and the first energy meter is determined by combining the taste evaluation type of each suction port, the real-time output power, and the current base power curve.

[0131] After step S63, the second energy table is also obtained in the following manner:

[0132] Step S65: Determine the second energy meter based on the suction characteristics obtained in step S64, the taste evaluation type of each suction port, and the real-time output power.

[0133] It should be noted that the process of determining the reference power curve, the first energy meter, and the second energy meter through taste calibration can occur either before the heated non-combustible device leaves the factory (completed by the manufacturer) or before or during use by the user (completed by the user).

[0134] The calibration and application process of a heated non-combustible device is illustrated below with a specific example:

[0135] The first step involves preparing 15 test prototypes with real-time power settings (the power curve can be adjusted in real time according to the suction taste, and the power has been calibrated) and 1050 aerosol-forming matrix monomers (hereinafter referred to as monomers). Furthermore, each test prototype is connected to an industrial control computer (e.g., a computer), allowing testers to score the taste via the industrial control computer. Simultaneously, the industrial control computer can record data during suction in real time, such as power and temperature.

[0136] The second step, as shown in Figure 2, involves randomly selecting 3 test prototypes (i.e., N1=3) (with pre-stored default power curves) and randomly selecting 30 individual cells for each prototype. The testers then use a standard suction method (e.g., 2 seconds of suction followed by 18 seconds of pause) to conduct the suction test. During the test, the power is adjusted based on the desired taste. Specifically, the current power value is retained when the taste is good, and adjusted when the taste is poor (specifically, the amplitude and duty cycle of the output power can be adjusted) until all 30 individual cells of each test prototype have been suctioned. At this point, each test prototype stores a power curve with relatively good taste: Power Curve 1, Power Curve 2, and Power Curve 3. The power curves from these three test prototypes are then fused and calculated to obtain the optimal power curve A (i.e., the third power curve).

[0137] The third step, as shown in Figure 3, involves setting the optimal power curve A onto the three test units (N3=3) from the second step, and randomly selecting 20 individual molecules for each unit. Furthermore, the testers employ a standard suction method, adjusting the power based on the desired taste during the test. Specifically, the current power value is maintained for good taste, while the current power value is adjusted for poor taste (specifically, the amplitude and duty cycle of the output power can be adjusted), until all 20 molecules in each test unit have been suctioned. At this point, the power curves with relatively good taste in each test unit can be identified: power curve 4, power curve 5, and power curve 6. The power curves from these three test units are then fused and calculated to obtain the optimal power curve B (i.e., the optimal power curve).

[0138] The fourth step, as shown in Figure 4, involves setting the power curve B across all 15 test units. 450 individual vapor cells are randomly selected, with 30 cells assigned to each test unit. Ten cells are drawn at room temperature, 10 at -35°C, and 10 at 45°C. Testers use standard vaping methods, scoring each puff's flavor across five dimensions: vapor production, aroma, smoothness, satisfaction, and impurities. A total score is calculated for all five. Simultaneously, power and heating element temperature are recorded in real-time (every 100ms). When scoring, each puff can be scored according to the following criteria: 1 point represents poor; 2 points represent average; 3 points represent good. For example, regarding "off-flavor," if the tester perceives a strong burnt taste, 1 point can be awarded; if the tester perceives an average burnt taste, 2 points can be awarded; and if the tester perceives no burnt taste or a slight burnt taste, 3 points can be awarded. After scoring each item, the scores for each item are added together to obtain the total score for that puff. Furthermore, 5-8 points represent poor taste; 9-13 points represent average taste; and 14-15 points represent good taste.

[0139] The fifth step, as shown in Figure 4, calculates the number of suction strokes, current suction depth, suction duration, and interval between each suction stroke based on the temperature information (using the temperature sensor only for suction detection). Then, by analyzing the taste scoring table, power, and temperature data, the energy distribution (power integral) for poor, average, and good taste in the first 14 strokes at room temperature, -35°C, and +45°C, respectively, is determined, along with the total energy distribution within 14 strokes.

[0140] Step 6: The energy per puff and total energy corresponding to the optimal taste at room temperature, -35°C, and +45°C, obtained in Step 5, are arithmetically averaged to obtain the average energy per puff and total energy data for optimal taste. Then, using linear interpolation, power curves C, D, and E are obtained at room temperature, -35°C, and +45°C within 0-300 seconds (300 seconds being the total suction time of one unit). Power curve C is used as the baseline power curve for adaptive energy control. Finally, by modeling power curves C, D, and E, the environmental variation coefficient (lamada) of the power curves at different ambient temperatures is found. For example, the environmental variation coefficient (lamada) corresponding to -35°C is: Environmental variation coefficient (lamada) = Power curve C / Power curve D.

[0141] Step 7, as shown in Figure 5, sets the power curve C and the environmental variation coefficient lamada for all 15 test units. Prepare the remaining 450 individual cigarettes, and smoke 30 individual cigarettes per test unit (10 cigarettes each at room temperature, -35°C, and +45°C). Furthermore, testers conduct random smoking tests (selecting appropriate intervals and smoking depths according to personal preference). During the test, the taste of each puff is scored from five dimensions: smoke volume, aroma, smoothness, satisfaction, and impurities. Power and heating element temperature are recorded in real-time (recording once every 100ms).

[0142] Step 8, as shown in Figure 5, analyze the taste scoring table, power, and temperature information. Specifically, calculate the number of puffs, puff depth, puff duration, and interval between puffs based on the temperature information. Based on the taste scoring table and power information, obtain the energy distribution of poor, average, and good taste for the first 14 puffs, as well as the total energy distribution within 14 puffs.

[0143] The ninth step involves processing the energy and total energy of each puff under poor and good taste conditions to obtain the compensation energy information corresponding to the number of puffs under good taste conditions at different intervals from the previous puff, and storing it in the first energy table. Additionally, it involves obtaining the total energy information corresponding to multiple puff durations under poor taste conditions and storing it in the second energy table.

[0144] Step 10, as shown in Figure 6, solidify the power curve C determined above, multiple environmental variation coefficients (lamada), the first energy meter under good taste and the second energy meter under poor taste into the above 15 test prototypes.

[0145] The eleventh step involves determining whether a suction action has occurred during actual suction based on the detected temperature information. If not, monitoring continues until a suction action is detected. At this point, the current suction characteristics are calculated, including: the current number of suction ports, the current suction depth, the suction duration of the current number of ports, and the interval between the current suction and the previous suction. This is then combined with the power curve C, the current environmental change coefficient, and the first energy meter to calculate the supply energy information (including base energy and compensation energy information). It is also crucial to ensure that this supply energy information does not fall within the energy range corresponding to the second energy meter. Finally, the supply energy is output. During output, the power can be increased initially and then decreased. After each adjustment cycle, the output energy is calculated, and it is determined whether the output energy matches the supply energy. If they do not match, power output continues in the next adjustment cycle until the output energy matches the supply energy. If they match, heating stops, and it is determined whether this is the last suction. If yes, the cycle ends; otherwise, a new suction action is detected, and a new cycle begins.

[0149] Energy determination steps: Based on the current pumping characteristics, determine the energy supply information for the current pumping operation;

[0150] Energy output steps: Output energy according to the stated energy supply information.

[0151] It should be understood that the control component can be an MCU, and the MCU implements the steps of the heating control method of the above-mentioned heating non-combustible device by executing the corresponding computer program.

[0152] Finally, it should be noted that although the terms "first," "second," etc., can be used in this document to describe various elements, components, times, and temperatures, these elements, components, components, times, and temperatures should not be limited by these terms. These terms are only used to distinguish one element, component, time, or temperature from another element, component, time, or temperature.

[0153] As used in this article, the term “and / or” includes any and all combinations of one or more associated listed items.

[0154] The aerosol generating matrix can be a solid aerosol generating matrix. Alternatively, the aerosol generating matrix can include solid and liquid components. The aerosol generating matrix can include tobacco-containing materials containing volatile tobacco flavor compounds that are released from the matrix upon heating. Alternatively, the aerosol generating matrix can include non-tobacco materials. The aerosol generating matrix may further include aerosol products. Examples of suitable aerosol products are glycerol and propylene glycol.

[0155] If the aerosol generating matrix is ​​a solid aerosol generating matrix, it may include, for example, one or more of a powder, granules, pellets, fragments, strands, strips, or sheets comprising, for example, vanilla leaves, tobacco leaves, tobacco stem segments, reconstituted tobacco, processed tobacco, homogenized tobacco, extruded tobacco, and expanded tobacco. The solid aerosol generating matrix may be in loose form or may be contained in a suitable container or box. For example, the aerosol-forming material of the matrix may be contained within paper or packaging paper and in the form of a stick. In the case where the aerosol generating matrix is ​​in the form of a stick, the entire stick, including any packaging paper, is considered the aerosol generating matrix.

[0156] Optionally, but not necessarily, the solid aerosol generating matrix may contain additional tobacco or non-tobacco volatile flavor compounds to be released upon heating of the matrix. The solid aerosol generating matrix may also contain capsules, such as those containing additional tobacco or non-tobacco volatile flavor compounds, and these capsules may melt during heating of the solid aerosol generating matrix.

[0157] The examples of temperature, time, and other values ​​in this article and accompanying figures are related to the material / size of the heating element, the composition / size of the aerosol-forming matrix, and the power supply and components used. Therefore, these temperature and time values ​​should not be limited by these examples.

[0158] In practical applications, the temperature sensing component in the heated non-combustible device actually detects the temperature of the heating element, preferably the temperature of the outer wall of the heating element. By controlling the temperature of the heating element, the heating temperature of the aerosol forming matrix is ​​controlled. Therefore, the temperatures of the heating element and the aerosol forming matrix are positively correlated, but not necessarily identical. That is to say, in some cases, the temperature of the heating element can be used to characterize the temperature of the aerosol forming matrix.
