[0004] In aerosol generation equipment, the temperature of the heater is typically controlled by pre-setting temperature control parameters using a heating algorithm when heating the aerosol generation matrix. Different aerosol generation matrices have different heating characteristics, and even for the same aerosol generation matrix, different heating temperatures may occur at different times. Generally, a corresponding heating curve is set for each aerosol generation matrix. Improving the accuracy of temperature control plays a crucial role in enhancing the taste of the generated aerosol. Summary of the Invention

[0052] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting the embodiments of this application.

[0053] In current related technologies, a typical heating curve for heating without combustion is shown in Figure 1, where the horizontal axis represents time and the vertical axis represents temperature. During the time period T0-T1, the heater is heated, causing its temperature to rise from room temperature W0 to temperature W1.

[0054] During the T1-T2 time period, the temperature of the heater is maintained at W1;

[0055] During the T2-T3 time period, the temperature of the heater is reduced so that its temperature drops from W1 to W2.

[0056] During the T3-T4 time period, keep the temperature of the heater at W2;

[0057] After T4, turn off the heating and allow the temperature to cool down naturally from W2 until it reaches room temperature.

[0058] The T0 to T3 stages are the preheating stages, and the T3 to T4 stages are the suction stages.

[0059] The duration of the preheating stage varies depending on the heating method and the aerosol generating matrix, ranging from 0 to 15 seconds. The suction stage (T3-T4) typically lasts 4 to 6 minutes, depending on the volume of the aerosol generating matrix. To rapidly generate aerosols, the preheating stage requires a rapid increase to a high temperature. To maintain consistent aerosol flavor, the suction stage usually maintains a relatively constant temperature, such as W1 (320-370℃) and W2 (300-360℃). In some embodiments, W2 can be a fixed value, such as 350℃, or it can be within a fixed range that varies slightly over time, such as gradually increasing, decreasing, or fluctuating within a fixed value.

[0060] Currently, the temperature control method in related technologies involves pre-determining the correspondence between the electrical characteristic values ​​of the heater (such as the current resistance value of the heater) and the temperature value, and then determining the current temperature value of the heater based on the current electrical characteristic values. However, in practical applications, the heater is generally welded to the aerosol generating matrix containment tube or the heater base. Due to heat conduction, the heater temperature is affected by the outer shell material of the aerosol generating device, which leads to a discrepancy between the temperature control parameters set based on the above algorithm and the actual measured temperature curve. This phenomenon is particularly pronounced in centrally located (i.e., the heater is fixed in the center of the aerosol generating matrix containment tube, and the heater is needle-shaped or plate-shaped, inserted into the aerosol generating matrix for heating) heated non-combustible aerosol generating devices.

[0061] Please refer to Figure 2. The temperature data compensation method in this embodiment of the application, used in an aerosol generating device, includes the following steps:

[0062] 01: Configure the first target parameter and the second target parameter.

[0063] The first target parameter is the heating time parameter, and the second target parameter is the heating temperature parameter corresponding to the first target parameter;

[0064] 02: Control the heater of the aerosol generating device to heat according to the first target parameter and the second target parameter;

[0065] 03: Obtain the actual temperature data of the heater of the aerosol generating device operating with the first target parameter and the second target parameter;

[0066] 04: Determine the target temperature compensation parameters based on the second target parameter and the actual temperature data;

[0067] 05: Control the heater of the aerosol generating equipment to operate at the target temperature control parameters.

[0068] The target temperature control parameter is determined based on the target temperature compensation parameter and the second target parameter.

[0069] The electronic device in this application can implement the above-described temperature data compensation method. Specifically, the electronic device includes a data configuration module, a temperature measurement module, a data processing module, and a device control module. The data configuration module is used to configure a first target parameter and a second target parameter. The temperature measurement module is used to acquire the actual temperature data of the heater of the aerosol generating device operating with the first and second target parameters. The data processing module is used to determine the target temperature compensation parameters based on the second target parameter and the actual temperature data. The device control module is used to control the heater of the aerosol generating device to heat according to the first and second target parameters, and to control the heater of the aerosol generating device to operate with the target temperature control parameters.

[0070] The aerosol generating device in this application embodiment can implement the above-described temperature data compensation method. Specifically, the aerosol generating device includes a memory and a processor, wherein the memory stores a computer program, the processor is used to configure a first target parameter and a second target parameter, and to control the heater of the aerosol generating device to heat according to the first target parameter and the second target parameter, and to acquire actual temperature data of the heater of the aerosol generating device operating with the first target parameter and the second target parameter, and to determine a target temperature compensation parameter based on the second target parameter and the actual temperature data, and to control the heater of the aerosol generating device to operate with the target temperature control parameter.

[0071] Specifically, in the current technical field of aerosol generation devices for users to inhale aerosols, heated non-combustible technology controls the temperature of the heater by executing pre-set temperature control parameters through a heating algorithm. These temperature control parameters have two dimensions: time and the desired target temperature the heater will reach. By controlling the heater to reach the set temperature within a set time using these parameters, a series of temperature-time correspondence data can be generated. In practical applications, the heater is welded to the heated non-combustible atomizer. Due to heat conduction, the heater's temperature is affected by the atomizer's body material, causing inconsistencies between the software-set temperature control parameters and the actual measured temperature curve. The software-set temperature control parameters cannot reflect the true temperature curve, causing inconvenience for equipment debugging and heating control.

[0072] To address the aforementioned problems, this application discloses a temperature data compensation method for an aerosol generating device. First, the temperature that the heater of the aerosol generating device needs to reach over a period of time is configured and set. This configuration is generally achieved by configuring two target parameters: a heating time parameter (corresponding to a first target parameter) and a heating temperature parameter (corresponding to a second target parameter).

[0073] Once the aforementioned time and temperature parameters are configured, the control module of the aerosol control device can control the heater to heat up according to these parameters. For example, the configured heating time parameter is 300 seconds and the heating temperature parameter is 350°C.

[0074] The control module of the aerosol control device, based on the aforementioned heating time and temperature parameters, uses the current moment as the initial time and controls the heater of the aerosol generating device to operate continuously at a temperature of 350°C for the next 300 seconds. Furthermore, during this continuous operation, temperature measuring devices such as temperature sensors installed in the aerosol generating device continuously acquire the actual temperature data of the heater during operation.

[0075] Next, using the heating temperature parameters mentioned above as reference values ​​and combining them with the actual temperature data, one or more sets of target temperature compensation parameters are obtained to compensate for the control temperature of the heater. Finally, in order to meet the needs of subsequent equipment debugging, based on the target temperature compensation parameters mentioned above, the target temperature control parameters that the heater should be configured to meet the target requirements during actual operation are calculated. This ensures that the actual temperature data of the heater when it responds to the target temperature control parameters matches the expectations, thereby meeting the needs of subsequent equipment debugging and aerosol generation mechanism heating tests.

[0076] Thus, this application can measure the temperature of the heater when controlling the temperature of the heater in the device based on time and temperature parameters, and perform numerical compensation based on the temperature measurement results. This ensures that the operating temperature of the heater is consistent with the pre-configured temperature parameters used to control the heater during actual operation, reducing the influence of heat conduction and other phenomena on the heater temperature, and accurately controlling the actual temperature of the heater. This facilitates the debugging of the equipment and further testing of the aerosol generation matrix, and helps improve the operational reliability of the aerosol generation equipment and the taste quality of the generated aerosol.

[0077] In some implementations, step 03 includes:

[0078] Acquire multiple temperature measurement data of the heater of the aerosol generating device within a preset time range.

[0079] In some implementations, the temperature measurement module is also used to acquire multiple temperature measurement data of the heater of the aerosol generating device within a preset time range.

[0080] In some implementations, the processor is also configured to acquire multiple temperature measurement data of the heater of the aerosol generating device within a preset time range.

[0081] Specifically, based on the above implementation method, considering the amount of data that the control module of the current aerosol generating device can process, a method of setting multiple measurement times within a preset time range is generally adopted. At each measurement time, a temperature measurement data point is acquired as the actual temperature data. For example, based on the above implementation method, within a 300-second heating element operating time range, taking the initial time as a reference, a measurement time point is taken every second, totaling 301 measurement times. At each of these measurement times, the temperature sensor or other temperature measuring device of the aerosol generating device is controlled to acquire the heating element's temperature data, resulting in 301 temperature data points. Each measurement time point has a unique temperature data point corresponding to it. In the above example, the time interval between measurement times can be adjusted according to actual conditions, and the amount of data acquired will also change accordingly.

[0082] In other examples, based on the above implementation, a 2-second time interval is taken from the initial starting point, followed by a 1-second interval, and then another 2-second time interval, and so on. Within the 300-second operating time of the heater, a total of 100 measurement time intervals of 2 seconds each can be obtained. Within each of these time intervals, a temperature measuring device, such as a temperature sensor controlling the aerosol generating device, acquires multiple temperature data points from the heater and averages them to obtain the average temperature for each time interval as the actual temperature data. Using this method, 100 sets of average temperature data can be obtained, with each of the above time intervals having a unique average temperature corresponding to it. In the above examples, the time interval for taking the time intervals and the total duration of the time intervals themselves can be adjusted according to actual conditions, and the amount of data obtained will also change accordingly.

[0083] Thus, this application provides a method for obtaining measured temperature data of the heater.

[0084] In some embodiments, the above-described temperature data compensation method further includes:

[0085] Based on each temperature measurement data and the corresponding measurement time, the fitting function relationship between the temperature measurement data and the measurement time is determined.

[0086] In some implementations, the data processing module is further configured to determine the fitting function relationship between the temperature measurement data and the measurement time based on each temperature measurement data and the measurement time corresponding to each temperature measurement data.

[0087] In some implementations, the processor is further configured to determine a fitting function relationship between the temperature measurement data and the measurement time based on each temperature measurement data and the measurement time corresponding to each temperature measurement data.

[0088] Specifically, based on the above implementation method, a temperature measurement method is adopted that takes multiple measurement moments within the operating time range of the heater and obtains the heater temperature corresponding to each measurement moment. For the convenience of data processing, in some examples, since the temperature data collected according to the above measurement method corresponds one-to-one with the measurement moment, each set of temperature data and measurement moment can be treated as an ordered pair and mapped to a Cartesian coordinate system to form a series of discrete points. For example, if the measurement moment is used as the quantity represented by the x-axis and the temperature data is used as the quantity represented by the y-axis, a series of discrete data points with (x, y) coordinates can be obtained. Then, based on these data points, the above-mentioned multiple discrete data points are fitted using data fitting methods in current related technologies to obtain a smooth curve. This curve corresponds to a fitting function relationship with the measurement moment as the independent variable and the temperature data as the dependent variable. Generally, the above-mentioned fitting methods include, but are not limited to, least squares, nonlinear, and higher-order polynomial fitting methods, which can be selected according to the actual situation. This application does not make specific limitations. The fitting result can be seen in the temperature curve shown in Figure 3.

[0089] The above fitting process yields the fitting function relationship between the measurement time and the measured temperature data within the aforementioned heating element operating time range. This transforms a large amount of discrete data into a continuous functional correspondence, thereby reducing the complexity of data processing.

[0090] Generally, the above fitting process can be implemented using MATLAB. For example, based on the above example, 301 measurement times, including the initial time, and the corresponding temperature measurement values ​​are input into MATLAB as discrete data points. Then, based on MATLAB's cftool fitting toolbox, a reasonable fitting method is selected using criteria such as curve coincidence and formula data volume to fit the above discrete data points, and finally, the above fitting function relationship is generated.

[0091] Thus, this application also uses the acquired temperature measurement data to fit a continuous functional relationship, and performs temperature compensation processing by processing the functional relationship.

[0092] Furthermore, in some embodiments, step 04 includes:

[0093] The temperature compensation function is determined based on the fitted function relationship and the second objective parameter;

[0094] In some implementations, the data processing module is also used to determine the temperature compensation function based on the fitted function relationship and the second target parameter.

[0095] In some implementations, the processor is also used to determine a temperature compensation function based on the fitted function relationship and the second target parameter.

[0096] Specifically, based on the above implementation method and having already obtained the fitting function relationship between the measurement time and temperature data, in some examples, the above-mentioned fitting function relationship can be used as a basis for data compensation based on the above-mentioned heating temperature parameters, so that the measured temperature data can be compensated to a degree that meets the target requirements.

[0097] For example, according to the example in the above implementation, the fitting function relationship between the measurement time and the temperature data is f(x), where x is the measurement time. Then, based on the above fitting function relationship f(x) and the heating temperature parameter 350℃, the temperature compensation function Δ(x) can be obtained, where x is the measurement time. The specific correspondence is as follows:

[0098] Δ(x) = 350 - f(x)

[0099] In this way, by determining the temperature compensation function based on the heating temperature parameters, it is possible to ensure that all temperature data obtained through the above measurement process can be stabilized near the heating temperature parameters after data compensation is performed. This compensates the measured temperature data to the pre-configured heating temperature parameters, thereby providing convenience and accuracy for subsequent equipment debugging and aerosol generation matrix debugging.

[0100] Thus, this application can use the fitted temperature-time function combined with preset temperature parameters to determine the compensation function for compensation.

[0101] Please refer to Figure 4. In some embodiments, step 05 includes:

[0102] 051: Determine the target temperature control function based on the temperature compensation function and the second target parameter;

[0103] 052: The heater of the aerosol generating device is controlled to operate according to the target temperature control function.

[0104] In some implementations, the device control module is also used to determine a target temperature control function based on a temperature compensation function and a second target parameter, and to control the heater of the aerosol generating device to operate according to the target temperature control function.

[0105] In some implementations, the processor is also configured to determine a target temperature control function based on a temperature compensation function and a second target parameter, and to control the heater of the aerosol generating device to operate according to the target temperature control function.

[0106] Specifically, based on the above implementation method, and having obtained the aforementioned temperature compensation function, when the heater operates under the same conditions the next time, the temperature sensor of the aerosol generating device measures the temperature of the heater. To ensure that the heater temperature is approximately equal to the preset heating temperature parameter of 350°C, compensation is required for the configured heating temperature parameter. For example, for a measurement time x within the operating time range, compensation can be performed based on the aforementioned temperature compensation function Δ(x) and the preset temperature parameter 350°C, resulting in the compensated target temperature control function t(x) at that measurement time.

[0107] t(x) = 350 + Δ(x)

[0108] Based on the temperature compensation function described above, the configured temperature parameters are compensated, which can bring the actual operating temperature of the heater to approximately the same level as the expected heating temperature parameter of 350℃, thus providing relatively accurate temperature conditions for subsequent debugging. Finally, the target temperature control function t(x) described above is used as the pre-configured temperature parameter, and the heater is controlled to operate based on the target temperature control function t(x).

[0109] For example, please refer to Figure 5. Figure 5 is a schematic diagram of the compensation result function obtained after data compensation based on Figure 3. The graph shows that the function value of the compensation result function is basically maintained at around 350℃, the pre-configured heating temperature parameter. In the above example, the target temperature control function exists in the form of a functional relationship.

[0110] Thus, this application can use the fitted temperature-time function combined with preset temperature parameters to compensate for the temperature measurement results.

[0111] In some implementations, step 04 further includes:

[0112] Based on the second target parameter, determine the temperature compensation data corresponding to the temperature measurement data at each measurement time.

[0113] In some implementations, the data processing module is further configured to determine temperature compensation data corresponding to the temperature measurement data at each measurement time, based on the second target parameter.

[0114] In some implementations, the processor is also configured to determine temperature compensation data corresponding to the temperature measurement data at each measurement time point based on the second target parameter.

[0115] Specifically, based on the above implementation method, in addition to using the fitting function to determine the compensation method of the compensation function, in some examples, the temperature data corresponding to each measurement time can be calculated one by one to obtain the temperature compensation data obtained from the temperature measurement data at each measurement time.

[0116] For example, according to the example in the above implementation, let the temperature measurement data corresponding to time x1 be f(x1). Based on the second target parameter mentioned above, the temperature compensation data Δ(x1) corresponding to time x1 can be obtained:

[0117] Δ(x1) = 350 - f(x1)

[0118] In this way, by determining the temperature compensation function based on the heating temperature parameters, it is possible to ensure that all temperature data obtained through the above measurement process can be stabilized near the heating temperature parameters after data compensation is performed. This compensates the measured temperature data to the pre-configured heating temperature parameters, thereby providing convenience and accuracy for subsequent equipment debugging and aerosol generation matrix debugging.

[0119] Thus, this application can also determine the corresponding compensation data for each measurement time based on a preset second target parameter, based on the temperature measurement result at each measurement moment.

[0120] Please refer to Figure 6. In some embodiments, step 05 includes:

[0121] 053: Based on the temperature compensation data and the second target parameter, determine the target temperature control data corresponding to each target time point;

[0122] 054: Control the heater of the aerosol generating equipment to operate at the corresponding target temperature control data at the target time.

[0123] In some implementations, the device control module is also used to determine the target temperature control data corresponding to each target time based on the temperature compensation data and the second target parameter, and to control the heater of the aerosol generating device to operate at the target time with the corresponding target temperature control data.

[0124] In some implementations, the processor is also configured to determine target temperature control data corresponding to each target time based on temperature compensation data and a second target parameter, and to control the heater of the aerosol generating device to operate at the target time with the corresponding target temperature control data.

[0125] Specifically, based on the above implementation method, according to the above approach, for any measurement time xi, there is a unique corresponding temperature compensation data Δ(xi). Therefore, when the heater operates under the same conditions the next time, the temperature of the heater is measured by the temperature sensor of the aerosol generating device. In order to ensure that the temperature of the heater is approximately equal to the preset temperature parameter of 350°C, compensation is required for the configured heating temperature parameter. For example, for any measurement time xi within the operating time range, compensation can be performed according to the above temperature compensation function Δ(x) and the heating temperature parameter 350°C to obtain the compensated target temperature control data t(xi) at that measurement time:

[0126] t(xi) = 350 + Δ(xi)

[0127] Based on the temperature compensation function described above, the configured heating temperature parameters are compensated, which means that the actual operating temperature of the heater can be compensated to be equal to the expected temperature parameters, thus providing relatively accurate temperature conditions for subsequent debugging. Finally, at any time xi within the running time range, the corresponding target temperature control data t(xi) is used as the pre-configured heating temperature parameters for that time xi to control the heater's operation. In the above example, the temperature compensation data exists in discrete form.

[0128] Thus, this application can obtain actual control data for controlling the operation of the heater based on compensation data and preset output temperature parameters, and control the operation of the heater according to the determined actual control data at the corresponding time.

[0129] Please refer to Figure 7. The temperature control method in this embodiment of the application, used in an aerosol generating device, specifically includes the following steps:

[0130] 001: Obtain the target temperature compensation value corresponding to the first target parameter, and the second target parameter.

[0131] The first target parameter is the heating time parameter, and the second target parameter is the heating temperature parameter corresponding to the first target parameter;

[0132] 002: Calculate the target temperature control parameters based on the target temperature compensation value and the second target parameter;

[0133] 003: Control the heater of the aerosol generating device to operate at the target temperature control parameters.

[0134] Furthermore, in some embodiments, the target temperature compensation value is calculated as follows:

[0135] Configure the first target parameter and the second target parameter.

[0136] The first target parameter is the heating time parameter, and the second target parameter is the heating temperature parameter corresponding to the first target parameter;

[0137] The heater of the aerosol generating device is controlled to heat according to the first target parameter and the second target parameter;

[0138] Acquire the actual temperature data of the heater of the aerosol generation device operating with the first target parameter and the second target parameter;

[0139] Based on the second target parameter and the actual temperature data, the target temperature compensation parameter is determined.

[0140] Specifically, the calculation method for the compensation value of the target temperature is described in the above implementation method and will not be repeated here.

[0141] In some examples, the first target parameter refers to the heating time parameter during the aspiration stage. To improve the user experience, the preheating time should be as short as possible. Reducing the precision of temperature control helps to shorten the preheating time. Improving the precision of temperature control during the aspiration stage helps to improve the taste of the aerosol.

[0142] For example, for an aerosol generating device, the heating time parameter is first configured as 200 seconds, and the corresponding heating temperature parameter is 350°C. Based on the heating time parameter and heating temperature parameter, and using the temperature control method described in the above embodiment, the target temperature compensation value at a certain moment can be obtained as -0.04°C. After compensation and correction, the target temperature control parameter at the aforementioned moment is 349.96°C. The heater of the aerosol generating device controls the energy supply of the heating element according to the resistance value corresponding to the temperature of 349.96°C, so that the resistance value of the heating element reaches the resistance value corresponding to 349.96°C, and finally achieves the goal of controlling the actual working temperature of the heating element to reach the aforementioned heating temperature parameter.

[0143] Thus, this application can measure the temperature of the heater when controlling the temperature of the heater in the device based on time and temperature parameters, and perform numerical compensation based on the temperature measurement results. This ensures that the operating temperature of the heater is consistent with the pre-configured temperature parameters used to control the heater during actual operation, reducing the influence of heat conduction and other phenomena on the heater temperature, and accurately controlling the actual temperature of the heater. This facilitates the debugging of the equipment and further testing of the aerosol generation matrix, and helps improve the operational reliability of the aerosol generation equipment and the taste quality of the generated aerosol.
