Description

Technical Field

[0001] This invention relates to the field of aerosol supply technology, and more particularly to a test method, apparatus, computer equipment, and computer-readable storage medium for evaluating the heating performance of a heating device under test. Background Technology

[0002] Heated non-combustible aerosol (THP) devices rely on heating elements or electrodes to heat cigarettes. The heating methods of these elements involve a wide variety of structural and material designs. In other words, many heating schemes can be designed for a single type of cigarette, primarily including resistance heating and inductive heating. However, even within these two main categories, there are different specific implementations. For example, even with resistance heating elements, the presence or absence of an infrared coating results in different heating effects.

[0003] In conclusion, evaluating the quality of a heating scheme based on the heating performance of cigarettes becomes an important task during the selection process. However, currently, assessing the quality of a heating element requires extensive testing with a large number of real cigarettes to determine if the heat generated by the heating element is sufficient. This testing method is not only unsuitable for accurately evaluating heating elements, but also for large-scale evaluation.

[0004] Therefore, there is an urgent need to propose a new testing method for evaluating the heating performance of the heating device under test in order to solve one or more of the above problems. Summary of the Invention

[0092] Aerosol-generating materials are materials capable of generating aerosols, for example, when heated, irradiated, or electrified in any other way. Aerosol-generating materials may be in solid, liquid, or gel form, and may or may not contain active substances and / or fragrances. In some embodiments, aerosol-generating materials may include “amorphous solids,” which may alternatively be referred to as “monolithic solids” (i.e., non-fibrous). In some embodiments, the amorphous solid may be a dried gel. An amorphous solid is a solid material that can retain some fluid (e.g., liquid) within it.

[0097] Consumables are articles comprising or composed of aerosol-generating materials, some or all of which are intended to be consumed by a user during use. Consumables may include one or more other components, such as an aerosol-generating material storage area, an aerosol-generating material delivery component, an aerosol-generating area, a housing, packaging paper, a nozzle, a filter, and / or an aerosol modifier. Consumables may also include an aerosol generator, such as a heater, which releases heat during use to cause the aerosol-generating material to generate an aerosol. The heater may, for example, comprise a combustible material, a material that can be heated by electrical conduction, or a sensor.

[0098] A sensor is a material that can be heated by being penetrated by a changing magnetic field (e.g., an alternating magnetic field). A sensor can be a conductive material, such that penetration by a changing magnetic field results in inductive heating of the heating material. A heating material can be a magnetic material, such that penetration by a changing magnetic field results in hysteresis heating of the heating material. A sensor can be both conductive and magnetic, allowing it to be heated by both heating mechanisms. In this paper, a device constructed to generate a changing magnetic field is referred to as a magnetic field generator.

[0099] Aerosol modifiers are substances typically located downstream of the aerosol generation region, configured to modify the generated aerosols, for example, by altering their taste, flavor, acidity, or other properties. Aerosol modifiers can be disposed in aerosol modifier release components operable to selectively release the aerosol modifier. For example, aerosol modifiers can be additives or adsorbents. For example, aerosol modifiers may include one or more of fragrances, colorants, water, and carbon adsorbents. For example, aerosol modifiers can be solid, liquid, or gel. Aerosol modifiers can be in powder, filament, or granular form. Aerosol modifiers may not contain filter material.

[0100] An aerosol generator is a device configured to cause the generation of aerosols from an aerosol-generating material. In some embodiments, an aerosol generator is a heater configured to subject the aerosol-generating material to heat energy in order to release one or more volatiles from the aerosol-generating material to form an aerosol. In some embodiments, an aerosol generator is configured to cause the generation of aerosols from an aerosol-generating material without heating. For example, an aerosol generator may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.

[0101] This disclosure relates to aerosol delivery systems (which may also be referred to as vapor delivery systems), such as aerosol sprayers or electronic cigarettes. In the following description, the terms "electronic cigarette" or "electronic cigarette" may sometimes be used, but it will be understood that this term is used interchangeably with aerosol delivery systems / devices and electronic aerosol delivery systems / devices. Furthermore, as is common in the art, the terms "aerosol" and "vapor," as well as related terms such as "evaporation," "atomization," and "aerosolization," are generally used interchangeably.

[0102] Aerosol delivery systems (electronic cigarettes) typically (though not always) comprise modular components, including reusable device parts and replaceable (disposable / consumable) cartridge components. Typically, the replaceable cartridge component will include aerosol generating material and an vaporizer (which may be collectively referred to as an "atomizer"), and the reusable device part will include a power source (e.g., a rechargeable power source) and control circuitry. It will be understood that these different parts may include additional components depending on their function. For example, the reusable device part will typically include a user interface for receiving user input and displaying operational status characteristics, and the replaceable cartridge device part may include, in some cases, a temperature sensor to aid in temperature control. The cartridge is electrically and mechanically connected to the control unit for use, for example, using threads, bayonet connections, or magnetic connections with suitably arranged electrical contacts. When the aerosol generating material in the cartridge is depleted, or when the user wishes to switch to a different cartridge with a different aerosol generating material, the cartridge can be removed from the reusable part, and a replacement cartridge can be attached to its appropriate position. Systems and devices that conform to this type of two-piece modular configuration can generally be referred to as two-piece systems / devices.

[0103] Electronic cigarettes typically have a generally elongated shape. For the sake of specific examples, some embodiments of this disclosure will be considered to include such a generally elongated two-piece system employing a disposable cartridge. However, it will be understood that the basic principles described herein can be equally applied to different constructions, such as single-piece systems or modular systems comprising more than two components, refillable devices and single-use disposable items, as well as other overall shapes, such as high-performance devices based on a so-called box-shaped pattern that typically has a box-like shape. More generally, it will be understood that some embodiments of this disclosure are based on aerosol delivery systems that are operatively configured to provide the functionality according to the principles described herein, and the construction aspects of the system configured to provide the functionality according to some embodiments of this disclosure are not of primary importance.

[0104] As described in the background section, existing methods for evaluating heating schemes require extensive testing with a large number of real cigarettes to determine whether the heat generated by the heating element is sufficient for the cigarette. This testing method is not only unfavorable for accurately evaluating the heating element, but also for large-scale evaluation.

[0105] Example 1

[0106] Figure 1 This is a flowchart of a test method for evaluating the heating performance of a heating device under test, provided in some embodiments of this application, with reference to... Figure 1 As shown, the method includes the following steps:

[0107] S100: Insert a simulated cigarette into a standard heating device to conduct a simulated smoking test, and obtain the target curve of the simulated cigarette with respect to temperature change.

[0108] This application addresses the problems existing in the prior art by proposing the use of simulated cigarettes instead of real cigarettes in simulated smoking tests within a heating device. The simulated cigarettes can be heated and smoked like real cigarettes. Firstly, the simulated cigarettes are made of heat-resistant materials, have the same dimensions as actual low-temperature cigarettes, and are not consumed during the test (i.e., the simulated cigarettes do not contain an aerosol-generating matrix). Therefore, the simulated cigarettes can be inserted into the heating device for simulated smoking without producing harmful substances. Secondly, since no aerosol-generating matrix is ​​consumed during the heating process, the simulated cigarettes can be recycled, thus eliminating the need to consume large quantities of real cigarettes and reducing testing costs. It is understood that the aerosol-generating matrix refers to the material that atomizes upon heating to generate an aerosol for the user to inhale.

[0109] As a preferred embodiment, in the facility example of this application, a thermocouple is provided in the simulated cigarette, so that the temperature change at the sampling point can be accurately measured, and a curve of the simulated cigarette with respect to temperature change can be generated based on the temperature change.

[0110] S200: Insert the simulated cigarette into the heating device under test for simulated smoking test, and obtain the test curve of the simulated cigarette with respect to temperature change.

[0111] As a preferred implementation, the method provided in this application uses an analogy method when evaluating the heating performance of the heating device. Therefore, it can be understood that the simulated puffing test performed by simulating the insertion of a cigarette into the heating device under test is the same as the simulated puffing test performed by simulating the insertion of a cigarette into a standard heating device. This makes the obtained test curve comparable to the target curve and improves the accuracy of the evaluation. It should be noted that the term "same puffing test" is not specifically limited here. In specific implementation, it can be set according to actual testing needs. For example, it can be a test with the same puffing cycle, a test using the same heating power, or a test with the same puffing cycle and the same heating power, etc., which will not be listed here.

[0112] Preferably, the heating device under test and the standard heating device are of the same type, which can improve the accuracy of the evaluation.

[0113] S300: Compare the test curve with the target curve to obtain the comparison result.

[0114] Specifically, as described above, when evaluating the heating performance of a heating device using the method provided in this application embodiment, an analogy method is preferably employed. In practice, simulated cigarettes are first inserted into both a standard heating device and the heating device under test for simulated smoking tests. Target curves and test curves of the simulated cigarettes with respect to temperature changes are obtained respectively. Then, the test curves are compared with the target curves to obtain the comparison results for subsequent operations. These subsequent operations include, but are not limited to, selecting heating devices with potential that are closest to the standard heating device from the heating devices under test.

[0115] It is understood that comparison algorithms can be used to compare the test curve and the target curve in the embodiments of this application. It should be noted that the embodiments of this application do not specifically limit the comparison algorithm; any known comparison algorithm can be used in this application without departing from the inventive concept. It should also be noted that the embodiments of this application do not limit the specific representation of the comparison results; the specific representation can be set according to actual needs without departing from the inventive concept. For example, the comparison results can be represented as a percentage or other numerical value.

[0116] In a preferred embodiment of this application, the method further includes the step of acquiring the standard heating device, comprising:

[0117] A real cigarette was placed in an actual heating device for a smoking test. The actual heating device was adjusted until it could bring out the flavor of the real cigarette to meet the set flavor requirements. The adjusted heating device was then used as the standard heating device.

[0118] It is understood that a standard heating device is any actual heating device that has been adjusted in various ways to best bring out the flavor of a real cigarette, that is, a standard heating device that can bring out the flavor of a real cigarette to meet the set flavor requirements. It should be noted that the set flavor requirements in the embodiments of this application are not specifically limited, and can be set according to actual testing needs without departing from the inventive concept of this application.

[0119] Preferably, in some specific embodiments, adjusting the actual heating device includes adjusting the heating properties of the actual heating device.

[0120] More preferably, in some specific embodiments, the heating properties include at least one of the type, material, size, heating power, and heating method of the heater of the actual heating device.

[0121] It is understood that the methods and contents of adjusting the actual heating equipment are not specifically limited in the embodiments of this application. Without departing from the inventive concept of this application, settings can be made according to actual testing needs. As an exemplary rather than restrictive description, in the embodiments of this application, a standard heating equipment can be obtained by adjusting the heating attributes of the actual heating equipment. These heating attributes include, but are not limited to, the type, material, size, heating power, heating method, etc. of the heater, and will not be listed exhaustively here.

[0122] In a preferred embodiment of this application, the suction test is performed after a predetermined suction cycle.

[0123] It should be noted that in this embodiment of the application, during the process of adjusting the actual heating equipment to obtain a standard heating equipment during the smoking test, a predetermined smoking cycle is set for the smoking test, thereby making the testing process more closely resemble the actual smoking process. The predetermined smoking cycle can be a complete smoking cycle of a real cigarette (also known as a smoking session), or it can be a smoking cycle set according to actual testing needs; no specific limitation is made here.

[0124] In a preferred embodiment of this application, the simulated cigarette does not contain an aerosol-generating matrix.

[0125] It is understood that the simulated cigarette in this application embodiment does not contain an aerosol generating matrix, so there is no consumption (i.e., consumption of the aerosol generating matrix to generate aerosol) during the smoking test, thus eliminating the need to consume a large number of cigarettes as in the test using real cigarettes, which can greatly reduce the testing cost.

[0126] In a preferred embodiment of this application, the target curve and the test curve include curves related to temperature changes obtained at preset sampling points of the simulated cigarette.

[0127] It is understood that the simulated cigarette in this embodiment has preset sampling points, and both the target curve and the test curve include curves related to temperature changes obtained at the preset sampling points. Preferably, the preset sampling points set within the simulated cigarette include multiple points, and the target curve and the test curve can be curves related to temperature changes obtained at the same preset sampling point, or curves related to temperature changes obtained at different preset sampling points. More preferably, the target curve and the test curve are curves related to temperature changes obtained at the same preset sampling point, which can further improve the accuracy of the evaluation.

[0128] In a preferred embodiment of this application, the target curve and the test curve include a curve of temperature variation with respect to space.

[0129] It is understood that, in some specific embodiments, the curves relating to temperature changes (including target curves and test curves) include curves relating temperature to spatial changes, such as temperature change curves at different locations in a simulated cigarette at the same time, etc., which are not specifically limited here.

[0130] In a preferred embodiment of this application, the target curve and the test curve include a curve of temperature change with time.

[0131] It is understood that in some other specific embodiments, the curves relating to temperature changes (including target curves and test curves) include curves relating temperature to time, such as temperature change curves at the same location in a simulated cigarette at different times, etc., which are not specifically limited here.

[0132] Reference Figure 2 As shown, in a preferred embodiment of this application, the method further includes:

[0133] S400: Select target devices that meet the preset requirements from the heating devices to be tested based on the comparison results.

[0134] Specifically, the testing method provided in this application, in practical applications, can screen out target devices that meet preset requirements from the heating devices under test based on the comparison results. It is understood that the target device is a heating device with potential that is closest to the standard heating device.

[0135] As a preferred implementation, in this embodiment of the application, comparing the test curve with the target curve to obtain the comparison result includes at least one of the following:

[0136] The temperature rise performance of the test curve is compared with that of the target curve to obtain the comparison results;

[0137] The temperature response performance of the test curve is compared with that of the target curve to obtain the comparison results;

[0138] The temperature thermal field distribution of the test curve is compared with that of the target curve to obtain the comparison results.

[0139] Specifically, in this embodiment of the application, the test curve and the target curve can be set as curves of temperature change with time, so that the test curve and the target curve can be compared from one or more dimensions such as temperature rise performance, temperature response performance, and temperature thermal field distribution to obtain the corresponding comparison results.

[0140] As a preferred implementation, in this embodiment of the application, the comparison of the temperature rise performance between the test curve and the target curve, and the acquisition of the comparison result, includes:

[0141] The slope of the test curve and the target curve during the heating phase is compared to obtain the comparison result.

[0142] It should be noted that the heating stage refers to the period after the cigarette is inserted into the heating device, before sufficient aerosol is generated for the user to inhale. The rate of increase can be represented by the tangent line of the curve, as shown in the reference. Figure 3 As shown, assuming Figure 3 Curve B is the target curve, and curves C1 and C2 are the test curves corresponding to different heating devices under test. objectiv If the target temperature is K, then the slope of the target curve B is K. B The ramp slopes of test curves C1 and C2 are K1 and K2, respectively.

[0143] It is understandable that the heating device for a real cigarette should heat the cigarette as quickly as possible to generate aerosol from the aerosol-generating matrix for the user to inhale. Therefore, the steeper the rise in temperature during the heating phase, the better. Based on this, as a preferred implementation, in this embodiment, when selecting target devices that meet preset requirements from the heating devices under test based on the comparison results, the heating device under test corresponding to the test curve with a steeper rise in temperature than the target curve can be selected as the target device.

[0144] Further reference Figure 3 As shown, the slope K1 of the test curve C1 is greater than the slope K of the target curve B. B The larger curve indicates that the heating device under test, corresponding to test curve C1, has better heating performance, and the time required for the user to inhale for the first puff can be shortened; the slope K2 of test curve C2 is greater than the slope K of the target curve B. B If we consider that the heating device under test corresponding to test curve C2 does not heat up quickly enough, it is not as fast as the standard heating device corresponding to target curve B.

[0145] As a preferred implementation, in this embodiment of the application, the step of comparing the temperature response performance of the test curve and the target curve to obtain the comparison result includes:

[0146] The areas enclosed by the test curve and the target curve and the reference constant temperature line are obtained and compared to obtain the comparison results.

[0147] The temperature corresponding to the reference constant temperature line is the target heating temperature of the standard heating equipment.

[0148] It's understandable that when a user inhales, the airflow causes temperature changes inside the cigarette. For example, taking the temperature at a sampling point inside the cigarette as an example, the temperature will initially decrease and then increase when the user inhales, but the goal of the heating equipment is to maintain the cigarette temperature as constant as possible. (Refer to...) Figure 4 As shown, assuming Figure 4 Curve B is the target curve, and curve C is the test curve corresponding to the heating device under test. T stable Using the baseline constant temperature line as an example, the slope of the target curve B in the cooling section is K. B The slope of the test curve C in the cooling section is K. C ΔT B The target curve B is relative to the reference constant temperature line T. stable The cooling rate, ΔT C The test curve C is relative to the reference constant temperature line T. stable The cooling rate, Δt B Let Δt be the rewarming time of the target curve B. C The temperature recovery time is for test curve C.

[0149] Further reference Figure 4 As shown, from the perspective of temperature response performance, the heating performance of heating equipment can be evaluated based on the following indicators:

[0150] 1. Since the slope of the curve is negative in the cooling section, the greater the slope of the curve in the cooling section, the slower the corresponding heating equipment cools down. That is, if K... C >K B This indicates that the heating device under test is less likely to cool down compared to the standard heating device;

[0151] 2. The curve is relative to the reference constant temperature line T. stable The less the temperature drop, the less the corresponding heating equipment cools down; that is, if ΔT C <ΔT B This indicates that the heating device under test cools down less than the standard heating device.

[0152] 3. The shorter the recovery time of the curve, the faster the corresponding heating equipment recovers its temperature, i.e., Δt C <Δt B This indicates that the heating device under test recovers temperature faster than the standard heating device.

[0153] In summary, the smaller the area enclosed by the curve and the reference constant temperature line, the better the temperature control potential of the corresponding heating device. Therefore, as a preferred implementation, in this embodiment, when selecting target devices that meet preset requirements from the heating devices under test based on the comparison results, the test device corresponding to the test curve whose enclosed area is not greater than the enclosed area formed by the target curve and the reference constant temperature line should be selected as the target device.

[0154] It is understandable that the area enclosed by the test curve, the target curve, and the reference constant temperature line can be calculated based on the cooling rate, the amount of cooling, and the recovery time. In specific calculations, relevant integral formulas can be used, but no specific limitations are made here.

[0155] As a preferred implementation, in this embodiment of the application, the step of comparing the temperature thermal field distribution of the test curve and the target curve to obtain the comparison result includes:

[0156] The deviations between the test curve and the target curve are compared to obtain the comparison results.

[0157] In a preferred embodiment of this application, the preset sampling points include multiple points; the step of comparing the deviation between the test curve and the target curve to obtain the comparison result includes:

[0158] The deviations of the test curves at each of the preset sampling points from the target curves are compared, and the sum of all deviations is taken as the comparison result.

[0159] It should be noted that the temperature thermal field reflects the overall heating effect of the cigarette. Since the contact points between the heating device and the cigarette differ, it doesn't mean that the best result is achieved when the temperature is uniform at every point. In actual cigarette heating, a segmented, zoned heating method is used. Therefore, it can be understood that in practice, the smaller the deviation between the test curve and the target curve, the closer the heating performance of the tested heating device is to that of a standard heating device.

[0160] In some specific embodiments, the preset sampling points set in the simulated cigarette include one; in other specific embodiments, the preset sampling points set in the simulated cigarette include multiple. It is understood that when there are multiple preset sampling points, when comparing the deviations of the test curve and the target curve, the deviations of the test curve and the target curve at each preset sampling point can be compared separately first, and then the sum of all deviations can be used as the final comparison result.

[0161] As a preferred implementation, in this embodiment of the application, the step of comparing the temperature thermal field distribution of the test curve and the target curve to obtain the comparison result includes:

[0162] Compare the slope of the test curve and the target curve during the heating phase to obtain a first comparison result;

[0163] The deviations between the test curve and the target curve during the stable suction phase are compared to obtain a second comparison result;

[0164] The first comparison result and the second comparison result are used as the comparison result.

[0165] In a preferred embodiment of this application, the preset sampling points include multiple points; the step of comparing the deviation between the test curve and the target curve during the stable suction phase to obtain a second comparison result includes:

[0166] The deviations between the test curves and the target curves at each of the preset sampling points during the stable suction phase are compared, and the sum of all deviations is taken as the second comparison result.

[0167] It is understandable that when there are multiple preset sampling points, when comparing the deviation between the test curve and the target curve, the deviation between the test curve and the target curve of each preset sampling point can be compared separately, and then the sum of all deviations can be used as the final second comparison result. This will not be elaborated here.

[0168] Reference Figure 5 As shown, assuming curve B1 is the target curve for the first preset sampling point, curve B2 is the target curve for the second preset sampling point, curve C1 is the test curve for the first preset sampling point (sample point 1), curve C2 is the test curve for the second preset sampling point (sample point 2), ramp-up corresponds to the heating stage, puff corresponds to the stable suction stage, and H1 and H2 are isothermal curves, then the ramp-up slopes of target curves B1 and B2 are K. B1 and K B2 The ramp slopes of test curves C1 and C2 are K and K, respectively. C1 and K C2 Here, 1 to n represent the sampling time. It can be understood that during the heating phase, a steeper slope of the curve indicates a faster heating rate; therefore, a steeper slope is better during this phase. Conversely, during the stable suction phase, a smaller deviation between the test curve and the target curve indicates that the heating performance of the tested device is closer to that of the standard heating device. Therefore, when comparing the temperature and thermal field distribution of the test curve and the target curve, the comparison can be divided into two parts: the heating phase and the suction phase, and performed separately.

[0169] In specific implementation, for the test curve and target curve during the heating phase, their ramp rates are compared to obtain a first comparison result. For the test curve and target curve during the stable suction phase, their deviations are compared to obtain a second comparison result. Finally, the first and second comparison results are combined as the overall comparison result. Based on this, as a preferred implementation, in this embodiment, when selecting target devices that meet preset requirements from the heating devices under test based on the comparison results, the first and second comparison results can be combined to select target devices from the devices under test. The specific selection criteria can be set according to actual product requirements and are not specifically limited here.

[0170] In one technical solution of the above-mentioned test method for evaluating the heating performance of the heating device under test, the deviation includes the root mean square error between the test curve and the target curve.

[0171] It should be noted that this application does not limit the specific method of comparing the deviation between the test curve and the target curve. Without departing from the inventive concept of this application, the method can be set according to actual testing needs. As an illustrative rather than restrictive explanation, in the embodiments of this application, the deviation between the test curve and the target curve can be represented by the mean square error of the two curves.

[0172] In practice, the root mean square error between the test curve and the target curve can be calculated using the following formula:

[0173]

[0174] Where i = 1 to n, 1 to n is the sampling time, ΔT i To measure the temperature difference between the test curve and the target curve at each sampling time, the root mean square error (RMSE) of this temperature difference is calculated. This yields an overall degree of agreement between the test curve and the target curve at the corresponding sampling points. Understandably, a smaller MSE indicates a higher degree of agreement, meaning the tested heating device closely approximates the performance of the standard heating device.

[0175] As a preferred implementation method, in this embodiment of the application, to improve the accuracy of the evaluation, only the deviation between the test curve and the target curve during the stable suction phase can be considered. Specifically, the root mean square error between the test curve and the target curve can be calculated using the following formula:

[0176]

[0177] Where m = 6, i = m ~ n, m to n is the sampling time during the steady-state suction phase, and ΔT iTo calculate the temperature difference between the test curve and the target curve at each sampling time, the root mean square error (RMSE) of this temperature difference is calculated. This yields the overall degree of agreement between the test curve and the target curve at the corresponding sampling points. Understandably, a smaller MSE indicates a higher degree of agreement, meaning the tested heating device closely approximates the performance of the standard heating device. However, this does not necessarily mean the tested heating device is the optimal device. If the agreement is close to the isothermal curve H, it indicates smaller fluctuations and better isothermal performance.

[0178] Understandably, the period from i=1 to i=5 (the heating phase) does not need to be included in the standard deviation calculation. We only need to focus on the increasing trend of the slope during this phase to judge the effectiveness of the heating device. In summary, the temperature measurement curves obtained by simulating cigarettes can easily help us identify potential heating elements and quickly discard those without potential. At this point, testing with real cigarettes becomes both economical and accurate.

[0179] As a preferred implementation, in this embodiment of the application, at least two of the preset sampling points are arranged at longitudinal intervals along the simulated cigarette and at least two of the preset sampling points are arranged at transverse intervals along the simulated cigarette.

[0180] Specifically, by setting at least two preset sampling points along the longitudinal interval of the simulated cigarette, the radial temperature change in the simulated cigarette can be tested. Similarly, by setting at least two preset sampling points along the transverse interval of the simulated cigarette, the transverse temperature change in the simulated cigarette can be tested, thereby improving the accuracy of the test.
