[0001] POWER PROVIDING METHOD FOR AEROSOL PROVISION SYSTEM AND AEROSOL PROVISION SYSTEM

[0002] Technical Field

[0003] The present application relates to the field of aerosol provision technology, particularly to a power providing method for an aerosol provision system and an aerosol provision system.

[0004] Technical Background

[0005] An aerosol provision system generally comprises a housing. Inside the housing, there is a cavity for accommodating aerosol - generating material, and a controller, a power source, and a heater are disposed within the accommodating cavity. Under the control of the controller, the power source supplies electric power to the heater, causing the heater to increase in temperature, thereby heating and atomizing the aerosol - generating material to produce an aerosol for the user to puff.

[0006] For current aerosol provision systems, although pre - testing is carried out to determine system parameters in an attempt to ensure that, during use, the power source capacity and the aerosol - generating material can be balanced, that is, they can be depleted simultaneously or almost simultaneously. However, in actual use, it often occurs that when the aerosol - generating material is depleted, there is remaining power in the power source, resulting in dry - burning, or when the power in the power source is depleted, the aerosol - generating material remains and is wasted. That is, there is a problem of system imbalance.

[0007] In addition, for current aerosol provision systems, after the puffing ends and the supply of electric power stops, the system is still at the atomization temperature and takes a certain period of time after the puffing ends to drop below the atomization temperature. This causes the aerosol - generating material to be atomized for a period of time after the puffing ends, resulting in the ineffective consumption of the aerosol - generating material and also the waste of electric energy.

[0008] However, through research, the applicant has found that the above - mentioned problems are all related to the system providing a fixed supply of electric power.

[0009] During the use of the aerosol provision system, the power source supplies a fixed electric power to the heater. This fixed electric power is generally obtained through testing, and it can make the power source capacity and the aerosol - generating material reach a balance under a preset single - puff duration. However, the actual single - puff duration of the user is difficult to predict. When the user's puff duration is longer than the preset single - puff duration, a relatively high proportion of the power is used for aerosol atomization after heating up. As a result, overall, the amount of aerosol - generating material that can be atomized per unit of power relatively increases, causing the power source to have remaining power when the aerosol - generating material is depleted. When the user's puff duration is shorter than the preset single - puff duration, due to a relatively high proportion of the power being used for heating up in the early stage of the puff, overall, the amount of aerosol - generating material that can be atomized per unit of power relatively decreases. Thus, when the power in the power source is depleted, the aerosol - generating material remains. That is, the amount of atomized aerosol is not simply linearly related to the magnitude of the power but is affected by the single - puff duration. The fixed - power method ignores the influence of the single - puff duration, thus causing the problem of system imbalance.

[0010] In addition, this fixed electric power needs to ensure that the system can heat up to the atomization temperature to generate an aerosol in the early stage of the puffing process. Consequently, this power keeps the system at the atomization temperature at the moment when the puffing ends. Since the change in temperature lags behind the supply of power, even if the power stops at the moment when the puffing ends, it takes a certain amount of time for the temperature to drop below the atomization temperature. As a result, for a period of time after the puffing ends, the temperature of the system can still atomize to produce an aerosol, causing the ineffective consumption of the aerosol - generating material and the waste of electric energy. That is, the supply of power ignores the different power requirements at different stages of the puffing process, resulting in the problem of waste of electric energy. And the different stages of the puffing process need to be determined according to the length of the single - puff duration.

[0011] Furthermore, the single - puff durations of different users may vary, and the single - puff durations of the same user for different puffs also vary, making it difficult to set the single - puff duration in advance. This further complicates the realization of system balance and energy conservation.

[0012] Therefore, there is an urgent need for a new aerosol provision system to solve one or more of the above - mentioned problems.

[0013] Summary

[0014] In accordance with some embodiments described herein, there is provided a power providing method for an aerosol provision system and an aerosol provision system, which determines the average duration of a single puff based on the user's historical puff duration habits, and determines the target power supply according to this duration, so as to facilitate the realization of balance and energy conservation of the aerosol provision system.

[0015] In accordance with a first aspect, there is provided a power providing method for an aerosol provision system. The method comprises: determining the average duration of a single puff for a user based on a puff duration of at least two preceding puffs before a current puff, and determining a target electric power and controlling a power source of the system to provide the target electric power to a heater of the system to heat the current puff based on an average duration of a single puff.

[0016] In embodiments, the average duration of a single puff is determined based on the user's historical puff duration habits, and this average duration of a single puff can more accurately reflect the possible duration of the user's current puff. Determining the target electric power for the current puff based on this duration can, compared with the prior art, facilitate the realization of the balance, energy conservation and other purposes of the system.

[0017] In embodiments of the or any of the above power providing method for an aerosol provision system, the system may have a balanced puff duration, wherein the balanced puff duration refers to a single puff duration required for depleting both the maximum amount of aerosol-generating material the system can accommodate and the power source under the premise that the power source operates at its maximum capacity to provide balanced power to the heater for heating.

[0018] In embodiments of the or any of the above power providing method for an aerosol provision system, determining the target electric power based on the average duration of a single puff comprises: if the average duration of a single puff is greater than the balanced puff duration, a first power is used as the target electric power to reduce the atomized aerosol amount relative to the balanced power. When the average duration of a single puff is greater than the balanced puff duration, it reflects that in the previous puffs, a relatively large amount of aerosol - generating material has been consumed, and the duration of the current puff is also very likely to be longer than the balanced puff duration. Therefore, the supplied power can be reduced to decrease the atomization amount, so as to avoid excessive consumption of the aerosol - generating material due to the relatively long average duration of a single puff, and prevent the aerosol - generating material from being depleted prematurely and causing dry - burning.

[0019] In embodiments of the or any of the above power providing method for an aerosol provision system, the first power corresponding to at least part of the duration segments of the average duration of a single puff may be less than the balanced power.

[0020] In embodiments of the or any of the above power providing method for an aerosol provision system, determining the target electric power based on the average duration of a single puff comprises: if the average duration of a single puff is less than the balanced puff duration, a second power is used as the target electric power to increase the atomized aerosol amount relative to the balanced power. When the average duration of a single puff is less than the balanced puff duration, it reflects that in the previous puffs, a relatively small amount of aerosol - generating material has been consumed, and the duration of the current puff is also very likely to be shorter than the balanced puff duration. Therefore, the supplied power can be increased to increase the atomization amount, so as to avoid too little consumption of the aerosol - generating material due to the relatively short average duration of a single puff, and prevent the power from being depleted prematurely and the aerosol - generating material from being wasted.

[0021] In embodiments of the or any of the above power providing method for an aerosol provision system, the second power corresponding to at least part of the duration segments of the average duration of a single puff may be greater than the balanced power.

[0022] In embodiments of the or any of the above power providing method for an aerosol provision system, determining the target electric power based on the average duration of a single puff may comprise: if the average duration of a single puff is equal to the balanced puff duration, the balanced power is used as the target electric power.

[0023] In embodiments of the or any of the above power providing method for an aerosol provision system, the power source may be a non-rechargeable battery.

[0024] In embodiments of the or any of the above power providing method for an aerosol provision system, determining the target electric power based on the average duration of a single puff comprises: taking a time elapsed by the average duration of a single puff as a time axis, the time axis is divided into at least two time periods along a time sequence; and the target electric power comprises power corresponding to each of the time periods, wherein the power corresponding to at least two time periods is different. Through this embodiment, time periods can be divided according to the puff duration, and the corresponding power can be determined according to the characteristics of each time period to save power.

[0025] In embodiments of the or any of the above power providing method for an aerosol provision system, the time axis is divided into multiple time periods along a time sequence, the multiple time periods comprise at least three time periods, the power corresponding to the multiple time periods is sequentially reduced. During the single - puff process, the early stage of the puff needs to be rapidly heated up to generate an aerosol, and the later stage of the puff can puff the aerosol generated in the early stage and needs to prepare for cooling down. Therefore, different time periods can be divided according to the puff duration, and the power of each time period can be decreased in a time sequence to save power while ensuring the puffing experience.

[0026] In embodiments of the or any of the above power providing method for an aerosol provision system, the power corresponding to the multiple time periods is reduced in geometric progression.

[0027] In embodiments of the or any of the above power providing method for an aerosol provision system, in the multiple time periods, the duration corresponding to the initial period in the time sequence of multiple periods is greater than at least one of the remaining time periods. In embodiments of the or any of the above power providing method for an aerosol provision system, in the multiple time periods, the durations corresponding to the multiple time periods after the initial period in the time sequence are the same.

[0028] In embodiments of the or any of the above power providing method for an aerosol provision system, if the average duration of a single puff is greater than the balanced puff duration, at least one of the power corresponding to the multiple time periods is less than the balanced power.

[0029] In embodiments of the or any of the above power providing method for an aerosol provision system, if the average duration of a single puff is less than the balanced puff duration, at least one of the power corresponding to the multiple time periods is greater than the balanced power. The balanced puff duration refers to a single puff duration required for depleting both the maximum amount of aerosol-generating material accommodated by the system and the power source under the premise that the power source operates at its maximum capacity to provide balanced power to the heater for heating.

[0030] In embodiments of the or any of the above power providing method for an aerosol provision system, controlling a power source of the system to provide the target electric power to a heater of the system to heat the current puff may comprise: providing the target electric power to the heater from the starting time on the time axis at the beginning of the current puff; and if the puff duration of the current puff is greater than the average duration of a single puff, for the exceeding duration, providing power to the heater according to the power corresponding to the end time of the time axis. Through this embodiment, when there is a deviation between the predicted average duration of a single puff and the actual puff duration, an appropriate power supply can be provided for the deviation period.

[0031] In embodiments of the or any of the above power providing method for an aerosol provision system, determining the target electric power and controlling a power source of the system to provide the target electric power to a heater of the system to heat the current puff based on the average duration of a single puff comprises: determining the target electric power curve along the time axis based on the average duration of a single puff, and controlling the power source to provide power to the heater according to the target electric power curve to heat the current puff.

[0032] In embodiments of the or any of the above power providing method for an aerosol provision system, the power source is rechargeable.

[0033] In embodiments of the or any of the above power providing method for an aerosol provision system, any power value in the target electric power is not less than a preset power and / or a duration of any power value in the target electric power is not less than a first preset duration. The preset power is the minimum electric power required by atomization of the heater to generate an aerosol or the minimum electric power required for the cartomizer to atomize to generate an aerosol amount acceptable to the user. The first preset duration is the minimum duration required by atomization of the heater to generate an aerosol or the minimum duration of the aerosol amount acceptable to the user by atomization of the cartomizer. Through this embodiment, it is ensured that the power supply can atomize to generate an aerosol, so as to avoid providing ineffective power supply.

[0034] In embodiments of the or any of the above power providing method for an aerosol provision system, determining the average duration of a single puff for a user based on the puff duration of at least the last two puffs before the current puff comprises: determining the average duration of a single puff for a user based on the puff duration of all puffs before the current puff, or determining the average duration of a single puff for a user based on the puff duration of puffs for a fixed preset count before the current puff, or determining the average duration of a single puff for a user based on the puff duration of all puffs in a second preset duration before the current puff, or based on the puff duration of puffs occurring before the current puff, wherein the time interval since the previous puff does not exceed the third preset duration, determining the average duration of a single puff for a user.

[0035] In accordance with a second aspect, there is provided an aerosol provision system. The system comprises: a heater configured to heat the aerosol - generating material in the system after being powered; a power source configured to supply electric power to the heater; and a controller configured to execute the method described in the first aspect to determine the target electric power and control the power source to provide the target electric power to the heater.

[0036] In accordance with a third aspect, there is provided a computer device. The device comprises a memory and a processor. The memory stores a computer program executable on the processor. When the computer program is executed by the processor, the method described in the first aspect is implemented.

[0037] In accordance with a fourth aspect, there is provided a computer - readable storage medium. The computer - readable storage medium stores a computer program. When the computer program is executed, the method described in the first aspect is implemented.

[0038] One or more of the above - mentioned solutions of the present invention have at least one or more of the following beneficial effects.

[0039] This application determines the average duration of a single puff based on the user's historical single - puff duration habits, and determines the target electric power based on this average single - puff duration. Since the average duration of a single puff can reflect the possible duration of the user's current puff and the historical consumption of the aerosol - generating material. Therefore, the solution of this application can comprehensively determine the target electric power for the current puff based on the possible duration of the current puff and the historical consumption of the aerosol - generating material. Compared with the fixed - power method in the prior art, this obviously facilitates the realization of system balance and energy conservation.

[0082] A susceptor is a material that is heatable by penetration with a varying magnetic field, such as an alternating magnetic field. The susceptor may be an electrically-conductive material, so that penetration thereof with a varying magnetic field causes induction heating of the heating material. The heating material may be magnetic material, so that penetration thereof with a varying magnetic field causes magnetic hysteresis heating of the heating material. The susceptor may be both electrically-conductive and magnetic, so that the susceptor is heatable by both heating mechanisms. The device that is configured to generate the varying magnetic field is referred to as a magnetic field generator, herein.

[0083] An aerosol-modifying agent is a substance, typically located downstream of the aerosol generation area, that is configured to modify the aerosol generated, for example by changing the taste, flavour, acidity or another characteristic of the aerosol. The aerosolmodifying agent may be provided in an aerosol-modifying agent release component, that is operable to selectively release the aerosol-modifying agent. The aerosol-modifying agent may, for example, be an additive or a sorbent. The aerosol-modifying agent may, for example, comprise one or more of a flavourant, a colourant, water, and a carbon adsorbent. The aerosol-modifying agent may, for example, be a solid, a liquid, or a gel. The aerosol-modifying agent may be in powder, thread or granule form. The aerosol-modifying agent may be free from filtration material.

[0084] An aerosol generator is an apparatus configured to cause aerosol to be generated from the aerosol-generating material. In some embodiments, the aerosol generator is a heater configured to subject the aerosol-generating material to heat energy, so as to release one or more volatiles from the aerosol-generating material to form an aerosol. In some embodiments, the aerosol generator is configured to cause an aerosol to be generated from the aerosolgenerating material without heating. For example, the aerosol generator may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.

[0085] The present disclosure relates to aerosol delivery systems (which may also be referred to as vapour delivery systems) such as nebulisers or e-cigarettes. Throughout the following description the term "e-cigarette" or "electronic cigarette" may sometimes be used, but it will be appreciated this term may be used interchangeably with aerosol delivery system I device and electronic aerosol delivery system I device. Furthermore, and as is common in the technical field, the terms "aerosol" and "vapour", and related terms such as "vaporise", "volatilise" and "aerosolise", may generally be used interchangeably.

[0086] Aerosol delivery systems (e-cigarettes) often, though not always, comprise a modular assembly comprising a reusable device part and a replaceable (disposable / consumable) cartridge part. Often, the replaceable cartridge part will comprise the aerosol-generating material and the vaporiser (which may collectively be called a "cartomizer") and the reusable device part will comprise the power provision (e.g. rechargeable power source) and control circuitry. It will be appreciated these different parts may comprise further elements depending on functionality. For example, the reusable device part will often comprise a user interface for receiving user input and displaying operating status characteristics, and the replaceable cartridge device part in some cases comprises a temperature sensor for helping to control temperature. Cartridges are electrically and mechanically coupled to the control unit for use, for example using a screw thread, bayonet, or magnetic coupling with appropriately arranged electrical contacts. When the aerosol-generating material in a cartridge is exhausted, or the user wishes to switch to a different cartridge having a different aerosol-generating material, the cartridge may be removed from the reusable part and a replacement cartridge attached in its place. Systems and devices conforming to this type of two-part modular configuration may generally be referred to as two-part systems / devices.

[0087] It is common for electronic cigarettes to have a generally elongate shape. For the sake of providing a concrete example, certain embodiments of the disclosure will be taken to comprise this kind of generally elongate two-part system employing disposable cartridges. However, it will be appreciated that the underlying principles described herein may equally be adopted for different configurations, for example single-part systems or modular systems comprising more than two parts, refillable devices and single-use disposables, as well as other overall shapes, for example based on so-called box-mod high performance devices that typically have a boxier shape. More generally, it will be appreciated certain embodiments of the disclosure are based on aerosol delivery systems which are operationally configured to provide functionality in accordance with the principles described herein and the constructional aspects of systems configured to provide the functionality in accordance with certain embodiments of the disclosure is not of primary significance.

[0088] Embodiment 1

[0089] Embodiment 1 of this application provides an aerosol provision system. Figure 1 is a composition diagram of the aerosol provision system of this application. It shows the composition of system 10 in a simplified manner, in which each part is not drawn to scale, and parts that are not relevant to the understanding of the solution of this application are omitted.

[0090] As shown in Figure 1 , the aerosol provision system 10 comprises a housing 100, and the housing 100 forms an internal cavity. An article insertion port 150 and an air inlet 160 are provided on the housing 100.

[0091] The aerosol provision system 10 further includes a controller 110, a power source 120, a heater 130, and an airflow sensor 140. The controller 110, the power source 120, the heater 130, and the air flow sensor 140 may all be arranged in the internal cavity.

[0092] Wherein, the controller 110 is used to control the power supply of the power source 120 to the heater 130, thereby controlling the system heating. It can be understood that the controller 110 can have various possible settings. The controller 110 may be programmable.

[0093] The power source 120 may be any suitable power source. In one embodiment, the power source is a non - rechargeable disposable power source. Or the power source is a rechargeable power source. In addition, in one embodiment, the power source can be a DC voltage source. In one embodiment, the power source is a lithium - ion battery. Or the power source may be a nickel - metal hydride battery, a nickel - cadmium battery, or a lithium - based battery, such as a lithium - cobalt, lithium - iron phosphate, or lithium - polymer battery.

[0094] The heater 130 may adopt various possible settings. As an example rather than a limitation, it may be a central heater such as a heating needle. In other possible examples, the heater may be in the form of a heating mesh, a heating coil, etc. This application does not specifically limit this.

[0095] The air flow sensor 140 is configured to obtain the air pressure in the system 10 to determine whether a user is puffing, so that the controller 110 may start the heating of system 10 accordingly.

[0096] The aerosol provision system 10 may further comprise a timer for providing time records. The timer may be integrated with or independent of the controller 110.

[0097] The controller 110 may also be configured to determine relevant time information based on the time recorded by the air flow sensor 140 and the timer. For example, it determines the start and end of the user's puffing according to the air pressure detected by the airflow sensor 140, and combines the time recorded by the timer to determine the duration of the user's single puff, the time interval between the user's previous and subsequent puffs, etc.

[0098] The controller 110 is further configured to perform the following:

[0099] Determine the average duration of a single puff for a user based on the puff durations of at least two puffs before the current puff, and determine the target electric power according to the average duration of a single puff, and control the power source 120 to provide the target electric power to the heater 130 to heat the current puff. The average duration of a single puff determined by this application based on the user's historical single - puff duration habits can more accurately reflect the possible duration of the user's current puff and the consumption of the aerosol - generating material in the past. Determining the target electric power based on this average single - puff duration makes the power supply related to the puff duration, solves a series of problems caused by the fixed power, and facilitates system balance and power saving.

[0100] It should be noted that Figure 1 and the above text only exemplify one structure of the aerosol provision system. The aerosol provision system can also have various possible variations. For example, a cartridge is provided at the product insertion port 150, or the air inlet 160 is arranged on the side of the housing 100. For another example, the aerosol provision system further includes a button or a display screen on the housing 100, etc. This application does not specifically limit this. How the controller 110 determines the average duration of a single puff, how to determine the target electric power, and how to control the heating according to the target electric power will be described in detail in Embodiment 2 and will not be repeated here.

[0101] Embodiment 2

[0102] Corresponding to Embodiment 1 above, Embodiment 2 provides a power providing method for an aerosol provision system. The aerosol provision system in Embodiment 2 can be the same as or substantially the same as the aerosol provision system in Embodiment 1. The power providing method in Embodiment 2 can be specifically implemented by the controller in the aerosol provision system.

[0103] Figure 2 is a flowchart of the power providing method for the aerosol provision system provided by an embodiment of this application. Referring to Figure 2, the method comprises the following steps.

[0104] S21. Determining the average duration of a single puff for a user based on the puff durations of at least two puffs before the current puff.

[0105] Usually, the user's puffing shows the same or similar habits within a certain period. That is, there is a high possibility that the duration of the user's current puff is related to the average single - puff duration of the user's historical puffs: for example, the duration of the user's current puff is the same as or close to the average single - puff duration. Based on this, this application uses the user's multiple historical single - puff durations to determine the average duration of a single puff, and uses this to reflect the possible duration of the current puff. In addition, this average duration of a single puff can also reflect the historical consumption of the aerosol - generating material as a whole.

[0106] Both the duration of the current puff and the historical consumption of the aerosol - generating material in the system are related to the determination of the target electric power. This application makes use of this to associate the target electric power of the current puff with the average duration of a single puff in the following, which is convenient for achieving the purposes of system balance, energy conservation, etc.

[0107] It should be noted here that in the embodiments of this application, the average duration of a single puff for a user can be determined in various possible ways. This application does not specifically limit the implementation method of this step. Under the premise of not violating the inventive concept of this application, the user can make settings according to actual needs. The following provides several examples in this application.

[0108] In one example, the average duration of a single puff for a user is determined based on the puff durations of all puffs before the current puff. Since all historical puffs are comprehensively considered, the error caused by the short - term fluctuation of the user's puffing behavior is avoided, and the user's single - puff duration habit can be determined more accurately, thus providing a premise for more accurately determining the target electric power later.

[0109] In another example, the average duration of a single puff for a user is determined based on the puff durations of a fixed number of puffs before the current puff. Considering all historical puffs will cause the problem of excessive data volume. Therefore, a fixed number of puffs can be selected as the basis for determining the average duration of a single puff to reduce the problem of excessive data volume. In a preferred embodiment, the fixed number can be selected to be greater than a first threshold and less than a second threshold to ensure that the data volume is neither too large nor too small.

[0110] In another possible example, the average duration of a single puff for a user is determined based on the puff durations of all puffs within a second preset duration before the current puff. The user's puffing habits have different characteristics in different periods. By selecting historical puffs by duration, on the one hand, the problem of excessive data volume can be reduced, and on the other hand, by setting the second preset duration, historical puffs of the user within a certain period can be selected to better reflect the user's puffing habits. The second preset duration can be selected as one day, one week, or one month, etc. according to needs. In a preferred embodiment, the second preset duration can also be related to the duration of a classic puffing session. For example, if the time for puffing a traditional cigarette is 4 minutes, taking this as the duration of a classic puffing session, then 1 minute (1 / 4 of the session duration) or 2 minutes (1 / 2 of the session duration) can be selected as the second preset duration.

[0111] In another possible example, the average duration of a single puff for a user is determined based on the puff durations of puffs whose time interval from the previous puff before the current puff does not exceed a third preset duration. This method can, on the one hand, reduce the problem of excessive data volume, and on the other hand, can select the concentrated puffs as historical puffs. Concentrated puffs are more likely to reflect the same puffing habits than scattered puffs.

[0112] Considering that there are inevitably some fluctuations during the user's puffing, in order to avoid the adverse effects of such fluctuations on the determination of the user's puffing habits. In the preferred embodiments of this application, filtering is also set for multiple puffs before the current puff, puffs that do not meet the preset conditions are filtered, and the average duration of a single puff is determined according to the durations of the filtered puffs. The preset conditions can be set according to needs, and this application does not limit this. As an example, the preset conditions can be set as not exceeding a duration threshold, or not being lower than a duration threshold, or being within a duration range, or the deviation from other puffs in multiple puffs not exceeding a preset value, etc. S22. Determining the target electric power based on the average duration of a single puff and control the power source of the system to provide the target electric power to the heater of the system to heat the current puff.

[0113] Specifically, the target electric power curve with the average duration of a single puff as the time axis can be determined, and the power source is controlled to provide power to the heater according to the target electric power curve to heat the current puff.

[0114] In the above - mentioned embodiments, the average single - puff duration is determined according to the historical puff duration habits. The average single - puff duration can reflect the historical consumption of the aerosol and the possible duration of the current puff. Therefore, determining the target power based on this is convenient for achieving the purposes of system balance, energy conservation, etc.

[0115] In step S22, the target electric power may be determined from the perspective of balancing the power capacity of the system power source and the consumption of the aerosol - generating material. As shown in Figure 3, in one embodiment, the target electric power may be determined based on the following method:

[0116] 531. Determining the relationship between the average duration of a single puff and the balanced puff duration.

[0117] 532. If the average duration of a single puff is greater than the balanced puff duration, then using a first power as the target electric power to reduce the atomized aerosol amount relative to the balanced power. An average duration of a single puff greater than the balanced puff duration means that a relatively large amount of aerosol - generating material has been consumed in the past, and it is also very likely that a relatively large amount of aerosol - generating material will be consumed in the current puff. Therefore, in the embodiments of this application, when the average duration of a single puff is relatively long, it is determined that the supplied power can reduce the atomization amount, so as to avoid excessive consumption of the aerosol - generating material due to the relatively long average duration of a single puff, and prevent the aerosol - generating material from being depleted prematurely and causing dry - burning.

[0118] The longer the duration, the greater the amount of aerosol atomized per unit of power (the proportion of power used for heating up is relatively small). Therefore, the power needs to be reduced to decrease the amount of atomized aerosol. In one example, the first power corresponding to the entire duration segment of the average duration of a single puff is less than the balanced power. Considering the need for rapid heating in the early stage of the puff, it can also be set that the power in only part of the duration segments of the average duration of a single puff, such as in the middle and later stages of the puff, is less than the balanced power. 533. If the average duration of a single puff is less than the balanced puff duration, then using a second power as the target electric power to increase the atomized aerosol amount relative to the balanced power. An average duration of a single puff less than the balanced puff duration means that a relatively small amount of aerosol - generating material has been consumed in the past, and it is also very likely that a relatively small amount of aerosol - generating material will be consumed in the current puff. Therefore, in the embodiments of this application, when the average duration of a single puff is relatively short, it is determined that the supplied power can increase the atomization amount, so as to avoid too little consumption of the aerosol - generating material due to the relatively short average duration of a single puff, and prevent the power from being depleted prematurely and the aerosol - generating material from being wasted.

[0119] The shorter the duration, the smaller the amount of aerosol atomized per unit of power (the proportion of power used for heating up is relatively large). Therefore, the power needs to be increased to increase the amount of atomized aerosol. In one example, the second power corresponding to the entire duration segment of the average duration of a single puff is greater than the balanced power. Considering the energy - saving scheme in subsequent embodiments, in another example, it can also be set that the second power corresponding to part of the duration segments of the average duration of a single puff, such as the early stage of the puff, is greater than the balanced power.

[0120] It should be noted that as the aerosol - generating material in the system is continuously consumed, to atomize and generate the same amount of aerosol, the required power needs to be continuously increased. Therefore, in optional embodiments, the target electric power may be further determined according to the consumption process of the aerosol - generating material when the current puff occurs.

[0121] For example, in a puffing session, the first puff occurs when the system is just activated and started, and there is a relatively large amount of aerosol - generating material remaining; the second puff occurs after the system has been started for a period of time, and there is a relatively small amount of aerosol - generating material remaining. The average duration of a single puff corresponding to both the first puff and the second puff is 3 seconds and is greater than the balanced puff duration. Then, the first power determined for the first puff at this time is less than the first power determined for the second puff. In this way, the consistency of the aerosol atomization amount at different puffing stages can be achieved to improve the user experience.

[0122] 534. If the average duration of a single puff is equal to the balanced puff duration, then using the balanced power as the target electric power.

[0123] It should be noted that the above - mentioned balanced puff duration refers to the single - puff duration required for depleting (including being almost simultaneously depleted) both the maximum amount of aerosol - generating material that the system can accommodate and the power source under the premise that the power source in the state of maximum power capacity supplies balanced power to the heater for heating. That is, for the power source and the aerosol - generating material in the initial state of the system, when the balanced power and the balanced puff duration are used for each puff, they are simultaneously depleted or almost simultaneously depleted (the remaining amount is within a preset range).

[0124] In step S22, the target electric power may be determined from the perspective of power saving of the system. As shown in Figure 4, in another embodiment of this application, the target electric power can be determined based on the following method:

[0125] 541. Dividing the time elapsed during the average duration of a single puff as a time axis into at least two time periods in a time sequence.

[0126] 542. Determining the power corresponding to each of the time periods as the target electric power, and the power corresponding to at least two of the time periods is different.

[0127] Through this embodiment, time periods can be divided according to the average duration of a single puff, and the corresponding power can be determined according to the characteristic requirements of each time period to save electric energy.

[0128] As mentioned above, during the single - puff process, the early stage of the puff needs to be rapidly heated up to generate an aerosol, and the later stage of the puff can puff the aerosol generated in the early stage and needs to prepare for cooling down. Therefore, in a preferred embodiment, the power corresponding to the time period later in the time sequence is less than the power corresponding to the time period earlier in the time sequence. In one example, the time axis is divided into multiple time periods in a time sequence. The multiple time periods include at least three time periods, and the power corresponding to the multiple time periods decreases in sequence. The solution of this embodiment can not only rapidly heat up in the early stage of the puff to generate an aerosol to ensure the puffing experience, but also reduce the power in the later stage of the puff to cool down in advance, so as to save power and avoid the ineffective consumption of the aerosol.

[0129] In one example, the power corresponding to the multiple time periods decreases in a geometric progression.

[0130] In another example, in the multiple time periods, the duration corresponding to the first time period in the time sequence is greater than at least one of the remaining time periods. This enables the system to rapidly heat up to the atomization temperature for atomization.

[0131] In another example, in the multiple time periods, the durations corresponding to the multiple time periods after the first time period in the time sequence are the same.

[0132] In another example, in the multiple time periods, the power supply of the time period at the end in the time sequence keeps the system below the atomization temperature, so as to ensure that the temperature gradually decreases and drops below the atomization temperature in the later stage of the puff.

[0133] In this application, the specific power level and time length of each time period are not specifically limited. The user can set them according to different aerosol - generating materials, different heaters, or different user tastes, so as to still achieve the desired taste in the power - saving mode.

[0134] The following is a specific scenario example under an energy - saving mode.

[0135] The average duration of a single puff is determined using the two historical puff durations before the current puff. The first puff before the current puff lasts for 1.8 seconds, and the second puff lasts for 2.2 seconds. Then the average duration of a single puff is: (1 .8 + 2.2)12 = 2 seconds.

[0136] The average duration of a single puff of 2 seconds is divided into 3 time periods, corresponding to different powers: the first 1 second is at the set power, the middle 0.5 second is at % of the set power, and the remaining 0.5 second is at of the set power. The set power needs to make the system heat up to the atomization temperature, and specifically can be the balanced power mentioned above.

[0137] The current puff of the system is heated according to the power of the time periods defined above. After heating for 2 seconds, the current puff continues. At this time, heating continues with of the set power for the last 0.5 second until the current puff ends.

[0138] Based on the above - mentioned energy - saving embodiment, and comprehensively considering the balance between the power of the system and the aerosol - generating material, in one embodiment of this application, the power supply for each time period can be further determined based on the following method: If the average duration of a single puff is greater than the balanced puff duration, then at least one of the powers corresponding to the multiple time periods is less than the balanced power.

[0139] If the average duration of a single puff is less than the balanced puff duration, then at least one of the power corresponding to the multiple time periods is greater than the balanced power.

[0140] The above - mentioned embodiments determine the target electric power according to the average duration of a single puff and control the heating of the current puff accordingly. In practical applications, there will be a certain difference between the duration of the current puff and the average duration of a single puff. Therefore, this application further provides the following method to complete the heating according to the actual duration of the current puff. At the beginning of the current puff, provide the target electric power to the heater from the starting time of the time axis. If the puff duration of the current puff is greater than the average duration of a single puff, then for the exceeding duration, provide power to the heater according to the power corresponding to the end time of the time axis. Through this embodiment, when there is a deviation between the predicted average duration of a single puff and the actual puff duration, an appropriate power supply can be provided for the deviation period.

[0141] It can be understood that if the puff duration of the current puff is less than the average duration of a single puff, heating can be carried out according to the time axis until the current puff ends. If the puff duration of the current puff is equal to the average duration of a single puff, heating can be carried out according to the time axis until the end of the time axis.

[0142] The method shown in Figure 3 aims at system balance, and the method shown in Figure 4 aims at energy conservation. In the same aerosol provision system, the target electric power can be determined based on one of these purposes or a combination of the two purposes. When determining based on multiple purposes, different target electric powers can be determined based on different purpose priorities. This application does not limit the specific priorities.

[0143] It should be noted that the above - mentioned methods can be applied to both rechargeable power sources and non - rechargeable disposable power sources. Relatively speaking, since disposable power sources cannot be recharged, more attention is paid to the balance problem. Therefore, the system of a disposable power source can take balance as the first - priority target. While a rechargeable power source can solve part of the balance problem through recharging, so the system of a rechargeable power source can take energy conservation as the first - priority target.

[0144] Although the above - mentioned methods mention that the target electric power can be determined according to the average duration of a single puff, in the pre - selected embodiments, the determination of the target electric power has some other limitations.

[0145] For example, any power value in the target electric power is not less than a preset power.

[0146] For example, the duration of any power value in the target electric power is not less than a first preset duration. The preset power is the minimum electric power required for the heater to atomize and generate an aerosol or the minimum electric power for the atomizer to atomize and generate an aerosol amount acceptable to the user; the first preset duration is the minimum duration required for the heater to atomize and generate an aerosol or the minimum duration for the atomizer to atomize and generate an aerosol amount acceptable to the user. Through this embodiment, it is ensured that the power supply can atomize to generate an aerosol, so as to avoid providing ineffective power supply.
