Description

Technical Field

[0001] The present application relates to the technical field of atomization devices, and particularly to a temperature compensation method, an atomization device, and a computer-readable storage medium. Background Art

[0002] Common atomization devices at least include a processor, an atomizer containing an aerosol-forming substrate, and a heating element for heating the atomizer. A fixed temperature-time curve for controlling the heating of the heating element is preset in the processor. During the heating stage, the heating element is controlled to heat according to this temperature-time curve, and the aerosol-forming substrate in the atomizer is heated by controlling the heating element to generate aerosol.

[0003] The taste of the atomization device is closely related to the heating temperature to a large extent, and the temperature-time curve is often related to the number of puffs of the user. Different users have different puffing habits. If the temperature of the atomization device drops too much between two puffs, it may take a long time to reach the ideal atomization temperature when puffing again, which will affect the continuity of the taste. At the same time, when the temperature drops to a certain extent, some components in the aerosol-forming substrate may condense into a liquid state to form condensate, which will also affect the taste of the electronic cigarette and may even damage the electronic cigarette device. On the contrary, if the atomization device remains at a high temperature between two puffs, a large amount of electric energy will be consumed.

[0004] Therefore, during the heating stage of the atomization device, it is necessary to compensate for it, which can not only improve the stability of the taste, avoid the generation of condensate, but also optimize the energy consumption management and adapt to the puffing frequencies of different users.

[0051] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and more detailed descriptions will be given later. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Description of the Embodiments

[0052] The present application will be further described in detail below in conjunction with the accompanying drawings through specific embodiments. Similar elements in different embodiments are denoted by related similar element numbers. In the following embodiments, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification to avoid overshadowing the core part of the present application with excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the descriptions in the specification and general technical knowledge in the art.

[0053] In addition, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method descriptions can also be reordered or adjusted in an obvious manner by those skilled in the art. Therefore, the various sequences in the specification and drawings are only for clearly describing a certain embodiment and do not mean a necessary sequence unless it is stated that a certain sequence must be followed.

[0054] The terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of this application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after. And the "connection" and "coupling" mentioned in this application, unless otherwise specified, both include direct and indirect connection (coupling).

[0055] As described in the background art, in an electronic atomization device, the core functional modules usually include a processor, a liquid storage chamber, a liquid guiding medium, an atomizer, and an electric heating element. Its working principle is as follows: The aerosol generating matrix (such as e-liquid) in the liquid storage chamber penetrates through the liquid guiding medium to the atomizer, and the electric heating element heats the atomizer under the control of the processor, so that the aerosol generating matrix is heated and atomized, and finally an aerosol that can be inhaled by the user is formed through the air flow. To achieve a stable atomization effect, a temperature-time curve is usually preset in the processor, and the heating power and duration of the electric heating element are accurately controlled through a closed-loop feedback system (such as the PID algorithm) to ensure that the atomization process meets the preset temperature requirements.

[0056] However, in actual use, the taste of the atomization device is closely related to the temperature control accuracy and faces significant technical challenges. First, the diversity of user suction habits leads to the complexity of temperature control: when the low-frequency suction user has a long interval between two suctions, the temperature of the atomizer may drop significantly, and it takes a long time to return to the ideal range (such as 200 - 250 °C) when suctioning again, which is likely to cause a weak taste or "cold start" phenomenon; while for high-frequency suction users, if the device operates at a high temperature continuously, it may cause carbonization of the aerosol matrix or shorten the lifespan of the electric heating element. Second, temperature fluctuations will cause secondary problems. For example, when the temperature of the atomizer is lower than the condensation point of the aerosol matrix (such as the mixed solution of propylene glycol / vegetable glycerin is about 120 - 150 °C), the unatomized liquid is likely to condense and form condensate in the atomization channel, which not only affects the taste consistency, but may also corrode the circuit or cause a short circuit after long-term accumulation. In addition, the traditional static temperature-time curve relies on a fixed heating mode and is difficult to dynamically respond to changes in the suction interval, resulting in the prominent contradiction between energy efficiency and taste: maintaining a high temperature can reduce condensate, but significantly increases energy consumption; reducing the temperature can extend the battery life, but increases the risk of condensation.

[0057] Therefore, the present application intends to propose a method that, based on the changes in the existing temperature-time curve and combined with the differentiated needs of users, compensates the temperature of the atomizer between two puffs of the user, that is, supplements energy between two puffs, so as to improve the taste consistency and reliability of the atomization device, and balance energy efficiency and user experience.

[0058] The following will specifically describe the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems with specific embodiments. These specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0059] Figure 1 It is a schematic structural diagram of an atomization device provided by an embodiment of the present application. As Figure 1 shown, the atomization device provided by this embodiment at least includes a heating chamber 110, a heating component 120, and a temperature control device 130.

[0060] The heating chamber 110 has a space for an atomizer with an aerosol-generating matrix. In some embodiments, the heating chamber 110 can be made of high-temperature-resistant materials such as ceramics or metals, and its interior is generally hollow and can accommodate an atomizer.

[0061] The heating component 120 is used to heat the atomizer to generate aerosol. In some embodiments, the heating component 120 can be arranged inside the heating chamber 110 and directly contact the outside of the atomizer. In some embodiments, the heating component 120 can be arranged on the outer side wall of the heating chamber 110, first heat the heating housing, and then heat the atomizer through the heating housing.

[0062] In some embodiments, the heating component 120 can be a heating tube and a coil, and the coil is configured to heat the heating tube by electromagnetic induction, and the heating tube contacts the side wall of the heating chamber 110; the heating tube is sleeved on the inner wall or outer wall of the heating chamber 110.

[0063] In some embodiments, the heating component 120 can be a resistively heated heating element, arranged on the inner wall or outer wall of the heating chamber 110. By using the electromagnetic induction method, the heating tube does not need to be connected to a circuit, so that the heating tube can be sleeved on the inner wall of the heating chamber 110 to directly contact the atomizer, and directly contact to heat the atomizer, which can quickly heat to the required temperature.

[0064] The temperature control device 130 is used to control the heating component 120 to heat according to a preset temperature-time change curve, so as to realize that the atomization matrix in the atomizer generates aerosol after being heated.

[0065] Figure 2The structural schematic diagram of the temperature control device provided by an embodiment of the present application. As Figure 2 shown, the temperature control device 130 provided by this embodiment includes an acquisition module 1301, a processing module 1302, and a compensation module 1303. Each of the above modules may be a functional module implemented by a processing chip, or multiple modules may be implemented by the same processing chip.

[0066] In this embodiment, the acquisition module 1301 is configured to acquire the temperature-time change curve for controlling the heating of the heating element during the heating stage.

[0067] The processing module 1302 is configured to determine the reference interval for temperature compensation according to the temperature-time change curve, and determine the temperature compensation value for the entire section of the temperature-time change curve according to the reference interval for temperature compensation and the preset temperature compensation strategy.

[0068] The compensation module 1303 is configured to perform temperature compensation on the heating temperature at the current moment according to the temperature compensation value for the entire section of the temperature-time change curve after detecting a suction action.

[0069] It should be noted that since the main improvement point of the present application is directed to the temperature compensation control of the heating component 120 by the temperature control device 130, therefore, the present application can be used for any heating non-combustion atomization device with an electric heating method through the temperature control device 130, having the technical effects of the above temperature control device 130, and not limiting the specific structure of the heating non-combustion atomization device. Other structures of the heating non-combustion atomization device provided by the present application (such as the housing, the cigarette tip structure, etc.) will not be elaborated herein.

[0070] Next, the specific process of the temperature compensation method for the temperature control device 130 will be described. Taking the heating non-combustion atomization device as an example, the heating non-combustion atomization device has a heating component 120 for heating the atomizer. The temperature compensation method provided by the embodiment of the present application specifically refers to the method of controlling the temperature of the heating element in the heating component 120 to achieve heating the atomizer to generate an aerosol.

[0071] Figure 3 The flowchart of the temperature compensation method provided by an embodiment of the present application. As Figure 3 shown, the temperature compensation method provided by this embodiment specifically includes the following steps:

[0072] Step S310: Acquire the temperature-time change curve for controlling the heating of the heating element during the heating stage.

[0073] For an atomization device, the atomizer therein can have multiple types or only one type. Atomizers of different types have different heating atomization temperatures. Therefore, the atomization device will use different heating curves to heat different types of atomizers. In actual applications, when the atomization device leaves the factory, one or more temperature control curves will be set in advance in its temperature control device 130.

[0074] Some embodiments of the atomization device may be applicable only to one type of atomizer. In this case, it is only necessary to pre-set the heating curve corresponding to the atomizer in the atomization device; some embodiments of the atomization device are applicable to multiple types of atomizers. In this case, it is necessary to pre-store the heating curves of multiple different types of atomizers in the atomization device. Among them, these heating curves have a one-to-one correspondence with the time period or the number of puffs.

[0075] In some embodiments, the preset heating curve is a temperature-time change curve in a heating mode based on the temperature-time relationship. For example, a first time period corresponds to a heating temperature, and a second time period corresponds to a heating temperature. The first time period and the second time period are consecutive time periods. The heating temperature corresponding to the number of puffs can increase first, then decrease, and then increase, or there is no limit on the size, which can be set according to the type of atomizer and the atomization device itself. The heating mode based on the temperature-time relationship is specifically: according to the preset heating temperature and time change relationship database, obtain the heating temperature corresponding to the current time, and heat according to the temperature.

[0076] Specifically, collect the relationship between the temperature and time change required for the atomizer to generate aerosol during the puffing process of multiple users, establish a database of the relationship between the heating temperature and time change during the heating process of the heating element, obtain the current time, that is, the time from the start of puffing to the current time, and according to the relationship between temperature and time change, obtain the heating temperature corresponding to the current time, and then control the heating element to heat according to this temperature.

[0077] In some embodiments, the preset heating curve is a temperature-time change curve in a heating mode based on the temperature-number of puffing ports relationship. For example, the first puff corresponds to a heating temperature, and the second puff corresponds to a heating temperature. The heating temperature corresponding to the number of puffs can increase first, then decrease, and then increase, or there is no limit on the size, which can be set according to the type of atomizer and the atomization device itself. The heating mode based on the temperature-number of puffing ports relationship is specifically: according to the preset database of the number of puffing ports and time change, obtain the heating temperature corresponding to the current number of puffing ports, and heat according to the temperature.

[0078] Specifically, during the aerosol generation process of the atomizer when multiple users are puffing, the relationship between the puff count and time change of the users is collected, a database of the puff count and time change during the heating process of the heating element is established, the current puff count at the current time is obtained, and according to the relationship between the puff count and time change, the heating temperature corresponding to the current puff count is obtained, and then the heating element is controlled to heat according to this temperature.

[0079] When the atomization device leaves the factory, one or more matching temperature-time change curves have been pre-set in its temperature control device 130. Under the control of an external signal, the heating component 120 heats according to this temperature-time change curve, and the atomization matrix in the atomizer will generate aerosol after being heated.

[0080] Step S320: Determine the reference interval for temperature compensation according to the temperature-time change curve.

[0081] In practice, whether it is the temperature-time change curve obtained based on the temperature-time relationship or the temperature-puff count relationship during the heating process, a stable temperature value will be maintained within one or more time intervals; even if a stable value cannot be maintained, it will change with a very small curvature within this interval, so it can also be regarded as maintaining a stable temperature range within this time interval.

[0082] Analyze the obtained temperature-time change curve to find one or more stable intervals or target temperature intervals of the curve. This interval is usually the desired temperature value or the temperature range to be maintained; select one or more intervals with stable temperature values and close to the target temperature as the reference interval for temperature compensation. For example: Suppose there is a temperature-time change curve, where the temperature rises from 20°C to 30°C within 0-10 minutes, then stabilizes at 30°C within 10-20 minutes, and then rises again. In this case, we can select the interval of 10-20 minutes as the reference interval because the temperature is stable within this interval.

[0083] Step S330: Determine the temperature compensation value for the entire section of the temperature-time change curve according to the reference interval for temperature compensation and the preset temperature compensation strategy.

[0084] The temperature compensation strategy usually adjusts the temperature values of other intervals according to the temperature value of the reference interval to achieve the purpose of reducing errors. The compensation strategy may include linear compensation, non-linear compensation, piecewise compensation, etc. Based on the temperature value of the reference interval and the preset compensation strategy, the temperature compensation values for multiple time intervals in the temperature-time change curve can be determined, or even the temperature compensation value for each time point.

[0085] In some embodiments, the temperature compensation strategy at least includes a temperature compensation reference value and a temperature target value for determining the temperature compensation value for the entire section of the temperature-time change curve.

[0086] It should be noted that the temperature compensation reference value is an important reference point in the temperature compensation process. In the entire section of the temperature-time change curve, one or more representative temperature points or temperature intervals are selected as the reference. These temperature points or temperature intervals are usually key points or extreme points in the temperature change range, such as the lowest temperature point / temperature interval. Based on these reference points or reference intervals, the compensation strategy for the entire temperature range can be further determined.

[0087] The temperature target value refers to the temperature value or temperature range that is expected to be achieved through temperature compensation in different temperature intervals. The target value is determined according to the performance requirements, stability requirements of the system or device, and the degree of influence of temperature change on performance.

[0088] In some embodiments, the temperature compensation strategy further includes a compensation formula or coefficient. According to the device characteristics and the temperature change range, a suitable compensation formula or coefficient is selected to calculate the temperature compensation value. These formulas or coefficients may be obtained based on experimental data, mathematical models, or empirical formulas.

[0089] Step S340: After detecting the suction action, perform temperature compensation on the heating temperature at the current moment according to the temperature compensation value of the entire section of the temperature-time change curve.

[0090] In some embodiments, at least one of a pressure sensor, a temperature sensor, a flow sensor, an air flow sensor, and a noise sensor can be provided in the atomization device. The suction behavior of the user is detected by at least one of the pressure sensor, the temperature sensor, the flow sensor, the air flow sensor, and the noise sensor above to detect whether the user has a suction action. For example, when the user uses a heat-not-burn atomization device and turns it on after installing a new atomizer, it can judge the user's suction action by collecting information such as pressure, temperature, air flow, gas, and noise generated by the user's inhalation operation.

[0091] After detecting the suction action of the user, perform compensation on the heating temperature of the heating component 120 at that moment according to the temperature compensation value corresponding to each time interval or time point of the determined temperature-time change curve, so as to ensure that the temperature of the atomizer is maintained between two suctions of the user, and avoid the user experience delay caused by the fact that the temperature of the atomizer will drop significantly due to natural heat dissipation between two suctions, and more energy and time are required to reheat to the target temperature during the next suction.

[0092] In summary, the temperature compensation method provided in this embodiment analyzes and determines the reference interval for temperature compensation by controlling the temperature-time change curve of the heating element according to the preset heating stage in the atomization device. Further, according to the preset temperature compensation strategy, the temperature compensation values for the entire temperature-time change curve are determined. Finally, after detecting the user's suction action, the heating temperature at the current moment is temperature-compensated according to the temperature compensation values for the entire temperature-time change curve determined, so as to achieve temperature compensation between two suctions of the user. This application maintains the temperature of the atomizer between two suctions, timely compensates for the energy consumption, shortens the temperature recovery time during the next suction, ensures that the ideal atomization state can be quickly achieved for each suction, and improves the user's taste coherence and experience. At the same time, it also effectively reduces the liquid residue, extends the service life of the device and ensures safety.

[0093] Figure 4 FIG. is a flowchart of a temperature compensation method provided in another embodiment of the present application. As Figure 4 shown, in the above embodiment, step S320: Determine the reference interval for temperature compensation according to the temperature-time change curve, which specifically includes the following steps:

[0094] Step S3201: During the temperature compensation process, divide the temperature-time change curve into multiple temperature intervals; wherein, each temperature interval has the same temperature value or the same temperature value range, and has a corresponding temperature target value.

[0095] As described above, whether the temperature-time change curve during the heating process is obtained based on the temperature-time relationship or the temperature-puff number relationship, it will maintain a stable temperature value (i.e., the temperatures of all points in the interval are equal) in one or more time intervals, or will maintain a stable temperature range with a very small curvature change in this interval (i.e., the temperatures of all points in the interval fluctuate within a specific range). Such a division helps us to more carefully understand the temperature change at different time points and formulate appropriate temperature compensation strategies for each interval.

[0096] During the temperature compensation process, the temperature-time change curve is divided into multiple temperature intervals. Each of these temperature intervals has the same temperature value or the same temperature value range, and also has a corresponding temperature target value. The target value is determined according to the sensitivity and stability requirements of the system or device for temperature changes. By adjusting these target values, we can ensure that the system or device can maintain stable performance in different temperature intervals. By subdividing the temperature range and setting specific temperature target values for each interval, precise control of temperature changes can be achieved.

[0097] Step S3202: Use the temperature range with the lowest temperature value among multiple temperature ranges as the reference range for temperature compensation.

[0098] When selecting the reference range for temperature compensation, usually the temperature range with the lowest temperature value among multiple temperature ranges is adopted. Low-temperature conditions often have a greater impact on the performance of the device. Therefore, using it as the reference range can better reflect the temperature compensation requirements of the entire device and help ensure the stability of the system or device under extreme low-temperature conditions.

[0099] Figure 5 It is a flowchart of the temperature compensation method provided by another embodiment of the present application. As Figure 5 shown, in the above embodiment, in step S330: Determine the temperature compensation value for the entire section of the temperature-time change curve according to the reference range for temperature compensation and the temperature compensation strategy, which specifically includes the following steps:

[0100] Step S3301: Determine the temperature compensation value of the reference range for temperature compensation as the temperature compensation reference value.

[0101] In this embodiment, the process of determining the temperature compensation value for the entire section of the temperature-time change curve is as follows: First, determine the temperature compensation value of the reference range for temperature compensation determined in the previous step. As at least the temperature compensation reference value and the temperature target value are included in the above temperature compensation strategy, that is, among the multiple ranges after dividing the temperature-time change curve, determine the reference range for temperature compensation, and the temperature compensation value of this range is determined as the temperature compensation reference value.

[0102] Step S3302: Calculate the first proportional relationship between the temperature target value corresponding to the reference range for temperature compensation and the temperature target value corresponding to each temperature range.

[0103] Step S3303: Determine the temperature compensation value corresponding to each temperature range according to the first proportional relationship and the temperature compensation reference value.

[0104] In this embodiment, after determining the temperature compensation value of the reference range, for the calculation of the temperature values of other temperature ranges, the relationship between the temperature target value corresponding to the reference range for temperature compensation and the temperature target values corresponding to each temperature range can be first used to determine the temperature compensation values corresponding to each range.

[0105] Specifically, assume that the temperature-time change curve is divided into n temperature ranges, and the temperature target values of each range are T1, T2,..., T n , where the temperature compensation reference value of the reference range is C base , and the corresponding temperature target value is T base , then,

[0106] The first proportional relationship between each temperature range and the reference range can be expressed as:

[0107] r i = T i / T base , i = 1, 2, …, n;

[0108] The expression of the temperature compensation value corresponding to each temperature range is:

[0109] C i = r i * C base , and further C i = T i / T base * C base , i = 1, 2, …, n.

[0110] In this way, we obtain the temperature compensation value corresponding to each temperature range.

[0111] In a specific embodiment, assuming that the temperature compensation reference value of the reference range is 45 °C, the corresponding temperature target value is 170 °C, and the temperature target value of another divided temperature range is 260 °C, then the temperature compensation value of this temperature range is 170 / 260 * 45 = 29.42 °C.

[0112] It should be noted that the determined reference range for temperature compensation is the range with the lowest temperature value among multiple temperature ranges. It can be understood that the temperature value to be compensated in this range is generally the highest value. Therefore, the temperature compensation values of other ranges can be calculated through the proportional relationship between the temperature target value of this range and the temperature target values of other ranges, and it can also ensure that the temperature compensation values of other regions do not exceed the temperature compensation value of the reference range. Therefore, the temperature compensation value of the reference range, that is, the temperature compensation reference value, is the maximum value of the temperature compensation. For other temperature ranges, in the case of high temperatures themselves, the compensated temperature value is further reduced to ensure that the temperature values after temperature compensation in all temperature ranges are within a controllable range, ensuring the safe use of the equipment.

[0113] Figure 6 This is the flowchart of the temperature compensation method provided by another embodiment of the present application. As Figure 6 shown, the temperature compensation method provided by this embodiment includes the following steps:

[0114] Step S610, obtain the temperature-time change curve for controlling the heating of the heating element during the heating stage.

[0115] Step S620, determine the reference range for temperature compensation according to the temperature-time change curve.

[0116] Step S630, determine the temperature compensation value for the entire section of the temperature-time change curve according to the reference range for temperature compensation and the preset temperature compensation strategy.

[0117] Among them, the implementation manners and the technical effects brought by steps S610 to S630 are the same as or similar to those of any of the above embodiments. To avoid repetition, they will not be elaborated here.

[0118] Step S640: After detecting the suction action, obtain the current suction time interval between the current suction action and the previous suction action.

[0119] Step S650: Determine the current temperature compensation duration according to the current suction time interval and the preset temperature compensation duration strategy.

[0120] Step S660: Perform temperature compensation on the heating temperature at the current moment according to the temperature compensation value of the entire temperature-time change curve and the current temperature compensation duration.

[0121] It can be understood that for the temperature compensation of the atomization device, it is necessary to perform temperature compensation between two suction actions. However, if the temperature compensation time between two suction actions is too long, it may also bring some impacts. For example, the heating element reaches the temperature compensation value through a long time. The long-term temperature compensation may cause the user to feel unsmooth during the next suction, and may also cause changes in the taste of the aerosol, such as becoming too strong or too thin. The inconsistency in taste will affect the user's suction experience and reduce the user's satisfaction and usage experience of the electronic cigarette. In addition, if the temperature compensation time is too long and the heating temperature is too high, more harmful substances such as formaldehyde and benzene, which are carcinogens, may be generated in the e-liquid of the electronic cigarette; and the long-term temperature compensation will also increase the burden on the battery, reduce the energy efficiency, and further cause the battery to overheat or be damaged, shortening its service life. Therefore, it is also very necessary to set the compensation duration for the temperature compensation between two suction actions.

[0122] In this embodiment, the temperature compensation duration between two suction actions is determined based on the time interval between two suction actions and the preset temperature compensation duration strategy. Specifically, first, the user's suction action is detected by sensors such as an airflow sensor and a pressure sensor, and then the current suction time interval between the current suction action and the previous suction action can be obtained; then, according to the current suction time interval and the preset temperature compensation duration strategy, the current temperature compensation duration is determined. Finally, temperature compensation is performed on the heating temperature at the current moment according to the temperature compensation value of the entire temperature-time change curve and the current temperature compensation duration.

[0123] In some embodiments, the temperature compensation duration strategy includes the maximum value of the preset suction time interval and the maximum value of the temperature compensation duration.

[0124] Precisely because the temperature compensation duration of the process may bring many adverse consequences, setting the maximum value of the temperature compensation duration related to the puffing time interval can effectively limit the working time of the heating element, thereby reducing the risk of equipment failure and damage, helping to maintain the quality and taste of the e-liquid, and enhancing user satisfaction. Further, correlating the maximum value of the temperature compensation duration with the maximum value of the puffing time interval can coordinately control the temperature compensation duration.

[0125] Figure 7 The flowchart of the temperature compensation method provided by another embodiment of the present application. As Figure 7 shown, in any of the above embodiments, in step S650, according to the current puffing time interval and the preset temperature compensation duration strategy, determine the current temperature compensation duration, which specifically includes the following steps:

[0126] Step S6501: Determine whether the current puffing time interval exceeds the maximum value of the puffing time interval.

[0127] Step S6502: When the current puffing time interval exceeds the maximum value of the puffing time interval, use the maximum value of the temperature compensation duration as the current temperature compensation duration.

[0128] It can be understood that the maximum value of the temperature compensation duration is related to the maximum value of the puffing time interval. The maximum value of the temperature compensation duration is determined in advance according to the performance of the atomization device and the user's usage habits. As long as the temperature compensation duration does not exceed the maximum value, it will not affect the use of the atomization device and the user experience. For a long period of time when the user does not puff, if the temperature compensation duration is not restricted, it is possible that the compensation temperature exceeds the expectation and remains at a high temperature for a long time. This will not only affect the taste of the e-cigarette but also may cause damage to the device. Therefore, when the current puffing time interval exceeds the maximum value of the puffing time interval, use the maximum value of the temperature compensation duration as the current temperature compensation duration.

[0129] In some embodiments, for the determination of the temperature compensation duration after the first puffing action, it can be a preset fixed value or the time interval between the end of the preheating stage and the first puffing action.

[0130] Step S6503: When the current puffing time interval does not exceed the maximum value of the puffing time interval, calculate the second proportional relationship between the current puffing time interval and the maximum value of the puffing time interval.

[0131] Step S6504: Determine the current temperature compensation duration according to the second proportional relationship and the maximum value of the temperature compensation duration.

[0132] After determining the temperature compensation duration corresponding to the case where the current pumping time interval exceeds the maximum value of the pumping time interval, for the case where the current pumping time interval does not exceed the maximum value of the pumping time interval, the maximum value of the temperature compensation duration can be proportionally shortened according to the proportional relationship between the current pumping time interval and the maximum value of the pumping time interval, so as to determine the temperature compensation duration for this time.

[0133] In a specific embodiment, assume that the maximum value of the set pumping time interval is 20 s, and the maximum value of the corresponding temperature compensation duration is 5 s. Then, if the pumping interval between two times of the user is greater than or equal to 20 s, the temperature compensation duration for this time is determined to be the maximum value of the temperature compensation duration, which is 5 s; if the pumping interval between two times of the user is less than 20 s, the maximum value of the temperature compensation duration is shortened in proportion. For example, if the current pumping interval between two times is 10 s, the temperature compensation duration for this time is determined to be 2.5 s, so as to ensure that in any case, the duration of temperature compensation will not exceed the maximum value, and the over-temperature situation will not occur, avoiding poor use effects.

[0134] The temperature compensation method described in any of the above embodiments is applied to a non-combustible atomizing device. In some embodiments, the heating component 120 of the atomizing device has at least two heating elements, which are distributed in the upper and lower sections of the atomizing device; the heating elements located in the upper section of the atomizing device and the heating elements in the lower section of the atomizing device correspond to different preset temperature-time change curves; the number of temperature intervals divided by different temperature-time change curves is different, and different temperature intervals have a temperature compensation reference value and a temperature target value.

[0135] It can be understood that for an atomizing device with heating elements in the upper and lower sections, through the cooperation of the upper-section heating element and the lower-section heating element, the effective utilization and control of the aerosol-forming substrate are realized. The upper-section heating element and the lower-section heating element each undertake different tasks. The main feature of the upper-section heating element is that the area of the aerosol-forming substrate it covers is relatively small, making the heat more concentrated, and it can reach the required heating temperature in a short time, enabling the atomizing device to quickly heat and generate aerosol at the beginning stage. Also, precisely because of the small area and concentrated heat, the upper-section heating element can be quickly started at the beginning stage of the heating process and rapidly generate aerosol. The main role of the heating of the upper-section heating element is also in the preheating stage, which can prepare for the subsequent heating of the lower-section heating element. Compared with the upper-section heating element, the lower-section heating element is usually designed to cover a larger area, so that the lower-section heating element can heat the aerosol-forming substrate more evenly and continuously, ensuring the stable generation of aerosol. The lower-section heating element works continuously during the heating process, and is responsible for heating the remaining aerosol-forming substrate to an appropriate temperature to produce continuous and stable aerosol. At the same time, by precisely controlling the heating temperature and power, the lower-section heating element can also optimize the taste, aroma and smoke volume of the aerosol.

[0136] Therefore, by presetting different temperature-time change curves for the upper heating element and the lower heating element of the atomization device, more precise control of the heating process can be achieved. At the same time, based on the main functions of the upper heating element and the lower heating element, different temperature ranges are divided respectively, and temperature compensation is carried out based on their respective temperature compensation reference values and temperature target values to ensure that the upper heating element and the lower heating element can reach the best working state in different working stages, thereby generating high-quality aerosol, which not only improves the working efficiency of the atomization device but also enhances the user experience.

[0137] In some embodiments, when dividing the temperature range for the temperature-time change curves corresponding to the upper heating element and the lower heating element, the temperature ranges corresponding to the upper heating element and the lower heating element can be the same or overlapping in a time period, which can ensure the continuity of the aerosol generated by the upper heating element and the lower heating element after temperature compensation and guarantee the user experience.
