[0003] However, this technology has certain limitations. During preheating, the absorbed energy of the aerosol matrix has not yet reached the standard for aerosol generation. At this time, if heating is paused due to personal operation errors or machine failures, etc., the partially heated aerosol matrix is difficult to reuse.

[0055] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. However, those skilled in the art should clearly understand that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present application.

[0056] It should be understood that when used in the specification of the present application and the appended claims, the term "comprising" indicates the presence of the described features, wholes, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or their combinations.

[0057] It should also be understood that in the description of this application, unless otherwise specified, the " / " used in the specification and appended claims of this application indicates that the objects associated before and after are in an "or" relationship. For example, A / B can represent A or B; the "and / or" in this application is merely a description of the association relationship of the associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. Here, A and B can be singular or plural. Also, in the description of this application, unless otherwise specified, "a plurality of" means two or more than two. "At least one (item)" or similar expressions refer to any combination of these items, including any combination of single items or plural items. For example, at least one (item) of a, b, or c can represent: a, b, c, a - b, a - c, b - c, or a - b - c, where a, b, c can be single or multiple.

[0058] In addition, for the convenience of clearly describing the technical solutions of the embodiments of this application, in the embodiments of this application, terms such as "first" and "second" are used to distinguish the same items or similar items with basically the same functions and roles. Those skilled in the art can understand that terms such as "first" and "second" do not limit the quantity and execution order, but are only used for differential description. Also, terms such as "first" and "second" are not necessarily different, nor can they be understood as indicating or implying relative importance.

[0060] The reference to "one embodiment" or "some embodiments" etc. described in the specification of this application means that a specific feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of this application. Thus, statements such as "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments" etc. that appear in different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in another way. The terms "comprise", "include", "have" and their variants all mean "include but not limited to", unless otherwise specifically emphasized in another way.

[0061] When the aerosol generating device is in the preheating operation, the energy generated by the heating element of the aerosol generating device has two destinations: part of the energy is transferred to the outer wall of the device by heat conduction due to the temperature difference inside and outside the device; and all the remaining energy is absorbed by the aerosol matrix. The dry-wet degree (water molecule content) of the aerosol matrix has a significant impact on its own heating rate. During the preheating and baking stage, as the heating continues, the water molecules in the aerosol matrix continuously dissipate, and the content gradually decreases, resulting in an accelerated heating rate of the aerosol matrix.

[0062] Based on this characteristic, to ensure the final normal generation of aerosol, the target temperature curve of the aerosol generating device will show a specific change: after the temperature rise reaches the highest point, the target temperature at the next time node will decrease, and this cycle continues until the preheating process ends. In addition, the energy generated by the heating element is positively correlated with both the temperature and the time duration, that is, the higher the temperature and the longer the heating time, the more energy is generated.

[0063] However, during the preheating period of the aerosol generating device, the energy absorbed by the aerosol matrix has not reached the standard for generating aerosol. At this time, if the heating is paused due to personal operation errors or machine failures, etc., the partially heated aerosol matrix is difficult to reuse.

[0064] Since the partially heated aerosol matrix cannot be reused, it not only increases the usage cost of the aerosol matrix, but also greatly reduces the user experience by frequently replacing the aerosol matrix.

[0065] An embodiment of a preheating processing method for an aerosol generating device is provided in the embodiments of the present application. Please refer to Figure 1 as shown Figure 1 The schematic flowchart of a preheating processing method for an aerosol generating device provided by the present application is shown. As an embodiment rather than a limitation, this method can be applied to or run in an aerosol generating device. The method includes:

[0066] S101, in response to the trigger of the start preheating instruction, determine the preheating mode flag bit of the aerosol generating device.

[0067] S102, determine the preheating working mode corresponding to the preheating mode flag bit.

[0068] S103, if the preheating working mode is the target preheating mode, then correct the preheating parameters in the standard temperature curve of the aerosol generating device to obtain the corrected temperature curve, where the target preheating mode is used to preheat at least part of the preheated aerosol matrix, and the preheating parameters include at least one of the total preheating duration and the target temperature corresponding to each time node.

[0069] S104, preheat the aerosol matrix in the aerosol generating device according to the corrected temperature curve.

[0070] In some alternative embodiments, the aerosol generating device pre-sets preheating mode flag bits corresponding to different preheating modes. Before triggering the preheating instruction, the user can switch different preheating mode flag bits through key operations to determine the final preheating mode to be adopted. The preheating mode flag bit can be a value stored in the memory (such as FLASH) of the aerosol generating device, and different values represent different preheating modes. For example, the preheating mode flag bit corresponding to the target preheating mode is 0, and the preheating mode flag bit corresponding to the conventional preheating mode is 1.

[0071] In some alternative embodiments, when the user triggers the start preheating instruction of the aerosol generating device (such as pressing the start preheating button on the aerosol generating device, issuing a voice instruction, etc.), the controller of the aerosol generating device receives the preheating instruction, and then queries whether the current preheating mode flag bit of the aerosol generating device is 1 or 0 by calling the flag bit discriminator. Different preheating modes are distinguished by different preheating mode flag bits, and then different preheating treatment strategies can be adopted according to different preheating modes, realizing flexible control of the preheating process of the aerosol generating device.

[0072] In some embodiments, a mode mapping table can be pre-stored in the controller of the aerosol generating device. This table records the correspondence between each preheating mode flag bit and the corresponding preheating working mode. The controller looks up and determines the corresponding preheating working mode in this mode mapping table according to the determined preheating mode flag bit. For example, the preheating mode flag bit of 1 corresponds to the normal preheating mode (i.e., the conventional preheating mode), and the preheating mode flag bit of 0 corresponds to the rapid preheating mode (i.e., the target preheating mode, which can also be called the power mode), etc.

[0073] In some embodiments, since a standard temperature curve is stored in the aerosol generating device, the standard temperature curve includes parameters such as the total preheating duration and the target temperature corresponding to each time node. When it is determined that the current preheating working mode is the target preheating mode (such as special modes like the power mode mentioned above), the aerosol generating device can adaptively correct the preheating parameters in the standard temperature curve.

[0074] It should be understood that different preheating working modes require different preheating effects. The target preheating mode is designed for special situations (such as dealing with a partially preheated aerosol matrix). By correcting the preheating parameters in the standard temperature curve, the preheating process of the partially preheated aerosol matrix can be made more in line with the actual requirements, avoiding over-preheating or under-preheating.

[0075] It should be noted that the preheated aerosol matrix has already absorbed a certain amount of energy but has not been used (such as being puffed). Its internal state (such as moisture content, activity level of components, etc.) is different from that of the non-preheated aerosol matrix. If the standard temperature curve of the conventional preheating mode is used to continue heating, the aerosol matrix will be over-baked and produce a burnt smell. Therefore, using the corrected temperature curve in the target preheating mode to preheat the preheated aerosol matrix can be reasonably adjusted according to the preheated state of the aerosol matrix, realizing reuse and ensuring a good puffing experience.

[0076] In some embodiments, the controller of the aerosol generating device can control the temperature of the heating element to the corresponding target temperature at different time nodes according to the corrected temperature curve. For example, at a certain time node, the corrected temperature curve requires the target temperature to be 200 °C, and the heating controller will adjust the heating power to make the temperature of the heating element reach and remain at 200 °C. By precisely controlling the temperature of the heating element and preheating the aerosol matrix according to the corrected temperature curve, the aerosol matrix can achieve the best atomization effect under appropriate temperature and time conditions, thus providing a better user experience.

[0077] Through the embodiments of the present application, the aerosol generating device can determine the corresponding preheating mode according to different preheating mode flag bits, and then execute different preheating treatment strategies to ensure that the aerosol matrix can be properly preheated in various situations. If the preheating working mode is the target preheating mode, the preheating parameters in the standard temperature curve of the aerosol generating device are corrected to obtain the corrected temperature curve, which can realize the reasonable reuse of the partially preheated aerosol matrix, and can avoid unnecessary overheating and reduce energy waste. For example, for a partially preheated aerosol matrix, shortening the total preheating duration and reducing the target temperature at some time nodes can make the aerosol generating device consume less energy while achieving the same preheating effect.

[0078] In one possible implementation, the method further includes:

[0079] If the preheating working mode is the conventional preheating mode, the aerosol matrix is preheated according to the standard temperature curve.

[0080] In some examples, the conventional preheating mode is used to preheat the non-preheated aerosol matrix.

[0081] When it is determined that the preheating working mode of the aerosol generating device is the conventional preheating mode, the aerosol generating device directly uses a pre-stored standard temperature curve to preheat the aerosol substrate placed in the aerosol generating device. This is because the conventional preheating mode mainly targets un-preheated aerosol substrates, and the standard temperature curve is designed according to the characteristics of un-preheated aerosol substrates, which can ensure that the un-preheated aerosol substrate is properly preheated to a usable state under normal circumstances, enabling the components inside the aerosol substrate to gradually reach an ideal atomization state, thereby generating a suitable aerosol.

[0082] It should be noted that the conventional preheating mode is used to process un-preheated aerosol substrates, while the target preheating mode is for partially preheated aerosol substrates.

[0083] By clearly distinguishing between the two preheating modes and their applicable objects, the aerosol generating device can select a suitable preheating method according to the actual state of the aerosol substrate, thereby improving the adaptability of the aerosol generating device to different usage scenarios. At the same time, for users, whether using a new aerosol substrate or re-preheating a partially heated aerosol substrate, the aerosol generating device can provide a suitable preheating treatment, thereby obtaining a better aerosol generation effect.

[0084] In one possible implementation, please refer to Figure 2 as shown, Figure 2 shows a schematic flowchart of a preheating treatment method for an aerosol generating device provided by the present application. S103, modifying the preheating parameters in the standard temperature curve of the aerosol generating device to obtain a modified temperature curve, including:

[0085] S201, obtaining a preheating proportionality coefficient corresponding to the aerosol substrate.

[0086] S202, modifying the preheating parameters in the standard temperature curve according to the preheating proportionality coefficient to obtain a modified temperature curve.

[0087] In some embodiments, in the aerosol generating device, for a preheated aerosol substrate (in the case of applying the target preheating mode), it is necessary to first determine a value that can reflect the preheated degree of the aerosol generating substrate, that is, the preheating proportionality coefficient. For example, by monitoring the temperature change of the heating element and time nodes within a specific time (such as the first 3 s), calculating the total energy value absorbed by the aerosol substrate, and comparing it with the pre-stored standard energy value, the preheating proportionality coefficient can be obtained.

[0088] It should be understood that different aerosol generating devices can adopt different specific algorithms to obtain the preheating proportionality coefficient according to their own designs and measurement methods, but the overall purpose is to quantify the degree of energy already absorbed by the aerosol substrate relative to the standard preheating energy.

[0089] After obtaining the preheating ratio coefficient R, the preheating parameters in the standard temperature curve can be adjusted by using the preheating ratio coefficient R. Specifically, the preheating parameters mainly include the total preheating duration and the target temperatures corresponding to each time node, etc. Taking the total preheating duration as an example, the original total preheating duration can be multiplied by the preheating ratio coefficient R to obtain the corrected total preheating duration; for each time node, it can also be adjusted according to the same ratio coefficient R, so that each time node is correspondingly shortened or lengthened. At the same time, the target temperature corresponding to the time node can also be modified according to the ratio coefficient R, such as multiplying the original target temperature by the ratio coefficient R to obtain the corrected target temperature.

[0090] In some embodiments, corresponding sensors can be provided in the aerosol generating device to monitor parameters such as the temperature and current of the heating element in real time, so that the energy absorbed by the aerosol matrix can be accurately calculated. For example, a temperature sensor is used to measure the temperature of the heating element, and the current and voltage values are obtained through a sampling circuit to calculate the resistance, etc. At the same time, the storage unit (such as FLASH) in the aerosol generating device is used to store data such as the standard temperature curve and the standard energy value, and can also store and process calculation results such as the preheating ratio coefficient.

[0091] In some other embodiments, the controller of the aerosol generating device can run a software algorithm to calculate the preheating ratio coefficient and correct the target temperature curve. Specifically, after the aerosol generating device enters the target preheating mode, the temperature calculation function and the energy calculation function are called at a predetermined frequency (such as 100 ms / time), the energy absorbed by the aerosol matrix is calculated according to the data collected by the sensor, and the preheating ratio coefficient is obtained by comparing with the standard energy value. Then, the preheating parameters in the stored standard temperature curve are modified according to the preheating ratio coefficient to generate a corrected temperature curve, and the corrected temperature curve is sent to the heating controller to control the heating element to heat the aerosol matrix based on the corrected temperature curve.

[0092] Due to different absorbed energies of different preheated matrices, the subsequent required preheating degrees are also different. By obtaining the preheating ratio coefficient corresponding to the preheated matrix and correcting the temperature curve accordingly, the preheating parameters in the standard temperature curve can be adjusted according to the actual situation, avoiding the problems of over-preheating or under-preheating, and ensuring that the aerosol matrix reaches the best atomization state.

[0093] Furthermore, for the preheated aerosol matrix, reasonable reuse can be achieved, rather than directly discarding it or following an inappropriate standard temperature curve as in the traditional method, which may cause damage to the matrix. Precise preheating control is achieved by automatically correcting the temperature curve according to the preheating ratio coefficient, enabling the preheated matrix to be correctly processed again, improving the utilization rate of the matrix, and reducing the user's usage cost. Moreover, the preheating strategy is automatically adjusted according to the actual state of the aerosol matrix without manual intervention by the user, providing a more convenient and intelligent usage experience for the user.

[0094] In one possible implementation, please refer to Figure 3 as shown Figure 3 FIG. shows a schematic flow chart of a preheating processing method for an aerosol generating device provided by the present application. S201, obtaining a preheating ratio coefficient corresponding to the aerosol matrix, including:

[0095] S301, obtaining the total absorbed energy value of the aerosol matrix within a predetermined time period.

[0096] S302, reading the standard energy value stored in the aerosol generating device.

[0097] S303, calculating the preheating ratio coefficient corresponding to the aerosol matrix according to the standard energy value and the total absorbed energy value.

[0098] In some embodiments, during the preheating of the aerosol matrix by the aerosol generating device, a specific time period (i.e., the predetermined time period, such as the first 3 seconds, or the first 2 seconds, or the first 5 seconds mentioned above) can be preset. Within this time period, the energy absorbed by the aerosol matrix is monitored and calculated in real time through the built-in sensors and related calculation modules of the aerosol generating device.

[0099] For example, the temperature of the heating element is measured at a fixed frequency (such as 100 ms / time), and according to the temperature change and the time interval, the energy calculation formula (such as P = (ΔT)^2 * t), where ΔT is the temperature difference and t is the real-time time node) is used to calculate the energy P absorbed by the aerosol matrix at each time node. Then, the energy values at each time node within the predetermined time period are accumulated to obtain the total absorbed energy value ∑P.

[0100] It should be understood that the standard energy value is a reference value preset and stored in the aerosol generating device, representing the energy that the aerosol matrix should absorb when being preheated from the initial state to the normal usable state under normal conditions without prior partial preheating.

[0101] When calculating the preheating ratio coefficient, the controller of the aerosol generating device can read the standard energy value from the storage unit, and calculate the preheating ratio coefficient corresponding to the aerosol matrix according to the standard energy value and the total absorbed energy. For example, by calling the energy calculation function, according to the real-time temperature value and time nodes, the energy value absorbed by the aerosol matrix at each time node is calculated using the energy calculation formula, and then the energy values at each time node within a predetermined period are accumulated to obtain the total absorbed energy.

[0102] By calculating the preheating ratio coefficient, the preheated degree of the aerosol matrix can be accurately quantified, enabling the aerosol generating device to make targeted corrections to the standard temperature curve based on the actual state of the aerosol matrix. Based on the accurate preheating ratio coefficient, the aerosol generating device can adjust the total preheating duration and the target temperature at each time node, thereby optimizing the preheating process, flexibly adjusting the preheating parameters, and improving the preheating efficiency. For example, for a matrix that has absorbed more energy, the total preheating duration can be shortened to reduce unnecessary heating time and save energy.

[0103] In a possible implementation, please refer to Figure 4 as shown in Figure 4 FIG. shows a schematic flow chart of a preheating processing method for an aerosol generating device provided in the present application. S301, obtaining the total absorbed energy of the aerosol matrix within a predetermined period, including:

[0104] S401, obtaining the current temperature value of the heating element in the aerosol generating device and the current time node corresponding to the current temperature value of the heating element.

[0105] S402, calculating the temperature difference between the current temperature value of the heating element and the historical temperature value, where the historical temperature value is the temperature value calculated at the previous time node of the current time node.

[0106] S403, determining the absorbed energy value corresponding to the current time node according to the temperature difference and the current time node.

[0107] S404, summarizing the absorbed energy values corresponding to multiple time nodes within a predetermined period to obtain the total absorbed energy of the aerosol matrix.

[0108] In some embodiments, when the aerosol generating device runs a preheating program, the temperature sensor of the aerosol generating device monitors the temperature value of the heating element in real time and transmits the measured temperature value to the controller of the device. The controller records the time point corresponding to each time the temperature value is obtained, that is, the current time node. For example, the aerosol generating device reads the temperature of the heating element at a fixed frequency of 100 ms, and each time it reads, it will obtain a current temperature value and the corresponding current time node (such as the time node at the 1st 100 ms, the time node at the 2nd 100 ms, etc.).

[0109] After obtaining the current temperature value and the current time node, the controller compares the current temperature value with the temperature value recorded at the previous time node (i.e., the historical temperature value) and calculates the temperature difference between the two. For example, when the current time node is the 3rd 100 ms, the historical temperature value is the temperature value recorded at the 2nd 100 ms, and the temperature difference ΔT between these two time nodes is obtained through subtraction operation. Furthermore, in the case where the temperature difference ΔT and the current time node t (the time interval is usually fixed, such as 100 ms) are known, the energy value P absorbed by the aerosol matrix at the current time node is determined using a specific energy calculation formula (P = (ΔT)^2 * t).

[0110] Within a predetermined time period (such as the first 3 seconds, the first 5 seconds, etc.), the aerosol generating device continuously obtains temperature values, calculates temperature differences, and absorbs energy values according to the above steps. For each absorbed energy value corresponding to a time node, the controller accumulates the absorbed energy values. When the end time of the predetermined time period is reached, the total sum of the absorbed energy values corresponding to all time nodes is the total absorbed energy value ∑P of the aerosol matrix within this predetermined time period.

[0111] By monitoring the temperature change of the heating element in real time and calculating the absorbed energy value at fixed time intervals, the energy absorbed by the aerosol matrix within a predetermined time period can be obtained more accurately. Since this method takes into account the dynamic change of temperature over time, compared with simple estimation methods, it can accurately reflect the actual energy absorption situation.

[0112] Moreover, by calculating the absorbed energy value in real time, the aerosol generating device can adjust the preheating process in a timely manner according to real-time data. For example, if it is found that the aerosol matrix absorbs energy too fast or too slow in a short period of time, the aerosol generating device can correspondingly adjust the heating power or preheating time of the heating element to ensure that the preheating process meets expectations and improve the accuracy and stability of preheating. Furthermore, the aerosol generating device can automatically calculate the preheating proportionality coefficient based on the total absorbed energy value and the preset standard energy value, and then intelligently adjust the preheating parameters to achieve more intelligent and personalized preheating control and enhance the user experience.

[0113] In one possible implementation, please refer to Figure 5 as shown in Figure 5 FIG. Figure 5 shows a schematic flow chart of a preheating method for an aerosol generating device provided by the present application. Obtaining the current temperature value of the heating element in the aerosol generating device includes:

[0114] S501, obtaining the temperature coefficient TCR value stored in the aerosol generating device and the initial resistance value of the heating element.

[0115] S502, collecting the current resistance value of the heating element in real time, and the ambient temperature value of the environment where the aerosol generating device is located.

[0116] S503, determining the current temperature value of the heating element based on the current resistance value, the initial resistance value, the ambient temperature value, and the TCR value.

[0117] In some optional embodiments, in the storage unit (such as FLASH) of the aerosol generating device, the temperature coefficient value (TCR, Temperature Coefficient of Resistance) of the heating element and the resistance value of the heating element in the initial state (usually refers to the aerosol generating device has not started heating or is in a specific initial condition), that is, the initial resistance value, are pre-stored. It should be understood that the TCR value is used to describe the characteristic of the resistance of the heating element changing with temperature, and the initial resistance value is used as a reference value to compare with the current resistance value of the heating element, so as to calculate the change amount of the resistance.

[0118] In some optional embodiments, the aerosol generating device can obtain the current resistance value of the heating element in real time through a resistance measurement circuit, and this resistance value changes with the temperature of the heating element. At the same time, since the ambient temperature will have a certain impact on the resistance of the heating element, a temperature sensor is used to measure the ambient temperature value of the environment where the aerosol generating device is located.

[0119] After that, according to the relationship formula between resistance and temperature in physics: the heating element temperature calculation function is based on the incoming current resistance value (R 当前阻值 ), the initial resistance value (R 初始阻值 ), the ambient temperature value (T 室温 ), and the TCR value, and uses the following calculation formula for calculation, and finally obtains the temperature value (T 当前温度值 ) of the heating element at the current moment:

[0120]

[0121] By comprehensively considering multiple factors such as the resistance change of the heating element, the temperature coefficient, and the ambient temperature, the current temperature of the heating element can be measured more accurately by using the above calculation method, which can ensure that the aerosol matrix is preheated under appropriate temperature conditions and improve the quality and performance of the product.

[0122] Moreover, the influence of the ambient temperature is considered during the calculation process, enabling the aerosol generating device to adapt to different environmental conditions. Whether in a high-temperature or low-temperature environment, the true temperature of the heating element can be calculated by accurately measuring the ambient temperature and combining with other parameters, thereby ensuring the stable operation of the aerosol generating device and the consistency of the preheating effect. Furthermore, the aerosol generating device can adjust the heating power or preheating time in real time according to the current temperature of the heating element, realizing a more intelligent preheating process control.

[0123] In a possible implementation manner, based on the current resistance value, the initial resistance value, the ambient temperature value, and the TCR value, determining the current temperature value of the heating element includes:

[0124] Obtain a preset first calling frequency.

[0125] At the first calling frequency, call the heating element temperature calculation function stored in the aerosol generating device based on the current resistance value, the initial resistance value, the ambient temperature value, and the TCR value, and calculate the current temperature value of the heating element.

[0126] In some optional embodiments, in the aerosol generating device, to monitor the temperature change of the heating element in a timely and accurate manner, a calling frequency for determining how often to calculate the current temperature value of the heating element, that is, the first calling frequency, can be preset. For example, setting the first calling frequency to 100 ms means calculating the temperature of the heating element every 100 milliseconds.

[0127] Control triggers the heating element temperature calculation function stored in the aerosol generating device at regular intervals according to the obtained first calling frequency, and each time it is called, the currently measured current resistance value of the heating element, the pre-stored initial resistance value, the ambient temperature value, and the temperature coefficient TCR value are passed as parameters into the heating element temperature calculation function. Furthermore, the heating element temperature calculation function calculates according to the passed-in current resistance value (R 当前阻值 ), initial resistance value (R 初始阻值 ), ambient temperature value (T 室温 ), and TCR value, and uses the following calculation formula for calculation, and finally obtains the temperature value (T 当前温度值 ) of the heating element at the current moment:

[0128]

[0129] By calling the heating element temperature calculation function at a fixed first calling frequency, the temperature change of the heating element can be monitored in real time and dynamically. The aerosol generating device can adjust the heating power in a timely manner according to the real-time temperature to ensure that the preheating process meets expectations. And by promptly detecting and handling temperature anomalies, such as too high or too low temperature of the heating element, it is possible to avoid malfunctions of the aerosol generating device due to temperature problems and extend the service life of the device.

[0130] In a possible implementation, determining the absorbed energy value corresponding to the current time node according to the temperature difference and the current time node includes:

[0131] Obtain a preset second call frequency.

[0132] At the second call frequency, call the absorbed energy function stored in the aerosol generating device, and calculate the absorbed energy value corresponding to the current time node based on the temperature difference and the current time node.

[0133] In the aerosol generating device, in order to accurately calculate the energy absorbed by the aerosol matrix at different time nodes, a call frequency for calculating the absorbed energy every certain period of time is preset, that is, the second call frequency. For example, it is set to 100 ms, which means calculating the absorbed energy value corresponding to the current time node every 100 milliseconds.

[0134] The controller periodically triggers the call of the absorbed energy function stored in the aerosol generating device according to the obtained second call frequency, and each time it is called, the previously calculated temperature difference and the current time node are passed as parameters to the absorbed energy function. Furthermore, the absorbed energy function calculates according to the incoming temperature difference and the current time node using the energy calculation formula P=(ΔT)^2*t, so as to obtain the absorbed energy value of the aerosol matrix corresponding to the current time node.

[0135] Through the embodiments of the present application, by calling the absorbed energy function at a fixed second call frequency, the absorbed energy value of the aerosol matrix can be accurately calculated at different time nodes, and the aerosol generating device can optimize the preheating process according to the actual energy absorption situation of the aerosol matrix. For example, for a matrix with fast energy absorption, the heating power can be appropriately reduced or the preheating time can be shortened; for a matrix with slow energy absorption, the heating power can be increased or the preheating time can be extended, thereby improving the preheating efficiency and quality.

[0136] In a possible implementation, after preheating the aerosol matrix in the aerosol generating device according to the corrected temperature curve, the method further includes:

[0137] Output a prompt message, where the prompt message is used to feedback that the preheating of the aerosol matrix has ended.

[0138] In some embodiments, the prompt message can have various forms, such as a sound prompt (emitting a specific prompt sound), a light prompt (flashing a light of a specific color), a screen display prompt (displaying relevant text information on the display screen of the device), etc.

[0139] In the embodiment of the present application, after the aerosol generating device completes the preheating process of the placed aerosol matrix according to the corrected temperature curve, the aerosol generating device may perform an additional operation, that is, output a prompt message to inform the user that the aerosol matrix has completed the preheating process and subsequent use operations can be carried out.

[0140] By outputting a prompt message in a timely manner after preheating the aerosol matrix in the aerosol generating device according to the corrected temperature curve, the user can clearly know when the aerosol matrix is preheated, avoiding confusion or incorrect operations caused by the user's uncertainty about the preheating state. Furthermore, the user can perform subsequent use in a timely manner according to the prompt message, improving the convenience and fluency of use, thereby enhancing the user experience.

[0141] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The execution order of each process should be determined according to its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

[0142] Corresponding to the preheating method of the aerosol generating device described in the above embodiments, Figure 6 is a schematic structural diagram of a preheating device of an aerosol generating device provided by an embodiment of the present application.

[0147] Through the embodiments of the present application, the aerosol generating device can determine the corresponding preheating mode according to different preheating mode flag bits, and then execute different preheating treatment strategies to ensure that the aerosol matrix can be properly preheated in various situations. If the preheating working mode is the target preheating mode, the preheating parameters in the standard temperature curve of the aerosol generating device are corrected to obtain a corrected temperature curve, which can realize the reasonable reuse of the partially preheated aerosol matrix, avoid unnecessary overheating, and reduce energy waste. For example, for a partially preheated aerosol matrix, shortening the total preheating duration and reducing the target temperature at some time nodes can enable the aerosol generating device to consume less energy while achieving the same preheating effect.

[0148] In a possible implementation, the preheating processing unit is further configured to, if the preheating working mode is the conventional preheating mode, preheat the aerosol matrix according to the standard temperature curve; wherein, the conventional preheating mode is used to preheat the aerosol matrix that has not been preheated.

[0153] In a possible implementation, the correction processing unit is further configured to: obtain the temperature coefficient TCR value stored in the aerosol generating device and the initial resistance value of the heating element; collect the current resistance value of the heating element and the ambient temperature value of the environment where the aerosol generating device is located in real time; determine the current temperature value of the heating element based on the current resistance value, the initial resistance value, the ambient temperature value, and the TCR value.
