Description

Technical Field

[0002] Currently, the power supply and endurance methods of aerosol generation devices have many drawbacks such as limited endurance and insufficient power supply flexibility.

[0003] First, the endurance is limited: As the battery capacity of the aerosol generation device gradually decreases, even though there is still remaining battery power, it cannot be fully and effectively utilized, resulting in the aerosol generation device being difficult to drive high-power loads and having poor endurance performance.

[0004] Secondly, the flexibility is severely insufficient. In the face of some special or comprehensive requirements, traditional aerosol generation devices lack flexible and practical power supply strategies, which greatly limits the applicability of the product in diverse application scenarios and the room for improvement of the user experience.

[0060] Currently, aerosol generating devices generally use a single battery to maintain power supply. This prior art has many drawbacks.

[0061] Firstly, the endurance is limited. As the aerosol generating device is used, the battery capacity gradually decreases. When the battery capacity drops to a certain level, the output power of the aerosol generating device also drops significantly, making it difficult for the device to drive high-power loads. Even if there is still remaining battery power, it cannot be fully and effectively utilized, resulting in poor endurance performance of the device and being unable to meet the long-term and high-intensity usage needs of users.

[0062] Secondly, the flexibility is severely insufficient. In the face of some special or comprehensive requirements, for example, in terms of reducing frequency noise, a single-battery-powered aerosol generating device lacks flexible and practical coping strategies and cannot dynamically adjust the device performance according to different usage scenarios and functional requirements, greatly limiting the applicability of the product in diverse application scenarios and the improvement space of the user experience.

[0063] To solve the above technical problems, an example of an aerosol generating device is provided in this application example. Please refer to Figure 1 as shown Figure 1 which shows a schematic structural diagram of an aerosol generating device provided by this application. The aerosol generating device includes:

[0064] A body 100, in which a first power supply element 101, at least one second power supply element 102 ( Figure 1 only one is schematically shown), an electrical load element 103, and a controller 104 are provided;

[0065] The first power supply element and the second power supply element are connected in parallel, and the first power supply element and the second power supply element after parallel connection are connected to the electrical load element. The capacity of the second power supply element is smaller than that of the first power supply element, and the capacity of the second power supply element and the capacity of the first power supply element conform to a predetermined proportional relationship;

[0066] A controller, connected to a first power supply element and a second power supply element, is configured to control at least one of the first power supply element and the second power supply element to supply electrical energy to an electrical load element according to the operating stage of the aerosol generating device and the proportional relationship between the capacity of the second power supply element and the capacity of the first power supply element.

[0067] Optionally, the first power supply element is a battery, for example, a high-capacity battery; the second power supply element is a battery or a capacitor, for example, a low-capacity battery. For example, taking the second power supply element as a battery, the capacity of the second power supply element can be 5%-10%, 20%-30%, or 10%-35% of the capacity of the first power supply element, etc. The present application does not specifically limit the specific proportional value, as long as the capacity of the second power supply element is less than the capacity of the first power supply element and the capacity of the second power supply element and the capacity of the first power supply element conform to a predetermined proportional relationship.

[0068] It should be understood that in the following examples, a second power supply element (such as a battery or a capacitor) is mostly used for illustration. However, when two or more second power supply elements are provided in the body, it is the same or similar to the embodiment in which one second power supply element is provided in one body, and for the example of the connection structure with more than one second power supply element, for the specific connection method of two or more second power supply elements, refer to the connection method of the first power supply element and the second power supply element.

[0069] In some examples, the capacity of the second power supply element and the capacity of the first power supply element conform to a predetermined proportional relationship, and this predetermined proportional relationship means that the capacity of the second power supply element is below a predetermined percentage of the capacity of the first power supply element (for example, below 35%, and the capacity of the second power supply element does not exceed 35% of the capacity of the first power supply element).

[0070] In some examples, the positive electrode of the first power supply element and the positive electrode of the second power supply element can be connected to each other, and the negative electrode of the first power supply element and the negative electrode of the second power supply element can also be connected to each other to form a parallel structure. The above connection method makes the voltage values at both ends of the first power supply element and the second power supply element equal, and they can jointly supply power to the electrical load element in the aerosol generating device.

[0071] In some examples, the parallel-connected first power supply element and second power supply element are connected to the electrical load element to provide the required electrical energy for the electrical load element. Optionally, in the examples of the present application, the electrical load element can be a key component in the aerosol generating device for heating the aerosol matrix to generate aerosol, such as heating elements like a heating body and a heating wire.

[0072] In the examples of this application, the controller is connected to the first power supply element, the second power supply element, and the electrical load element respectively. In some examples, the controller can monitor parameters such as voltage, current, and power of the power supply element in real time through sensors in the aerosol generating device, as well as the working state of the electrical load element.

[0073] In some examples, a predetermined proportional relationship between the capacity of the second power supply element and the capacity of the first power supply element can be determined in advance according to the actual requirements of the aerosol generating device. For example, when the second power supply element is mainly used for auxiliary power supply, the capacity of the second power supply element can be set to 20%-30%, 10%-35%, etc. of the capacity of the first power supply element.

[0074] In some examples, the operating stages of the aerosol generating device include but are not limited to: preheating stage, non-preheating stage (normal working stage), standby stage.

[0075] In some examples, when the aerosol generating device starts the preheating stage or other high-power stages, if the capacity ratio of the second power supply element to the first power supply element meets the predetermined proportional relationship (for example, 20%-30%, 10%-35%), since the power demand of the electrical load element is large, the controller controls the first power supply element and the second power supply element to supply power to the electrical load element simultaneously, so as to provide sufficient power to meet the requirements of the high-power load element, extend the battery life of the device, improve the flexibility of power supply, and avoid the situation that the electrical load element cannot be driven due to insufficient output power of a single power supply element.

[0076] For example, in the preheating stage of the aerosol generating device, electrical load elements such as the heating wire of the aerosol generating device require a large amount of power to quickly heat up. By controlling the first power supply element and the second power supply element to work together to supply power to the electrical load element, the normal startup of the aerosol generating device can be ensured.

[0077] In some examples, in the low-power stage when the aerosol generating device is working normally, the controller can preferentially let the first power supply element supply power to the electrical load element according to the power of the power supply element, while the second power supply element is in a standby state. When the power of the first power supply element drops to a predetermined proportion (for example, below 20% of the power of the first power supply element), the controller then enables the second power supply element to assist in power supply, or lets the second power supply element supply power alone, so as to make full use of the power of each power supply element, improve the overall battery life, and avoid the situation that the remaining part cannot be utilized due to the exhaustion of the power of a single power supply element.

[0078] An example of an aerosol generating device provided by an application example. By setting a first power supply element and a second power supply element in parallel in the aerosol generating device, and connecting the first power supply element and the second power supply element after parallel connection to an electrical load element. Since the capacity of the second power supply element is smaller than that of the first power supply element, and the capacity of the second power supply element and the capacity of the first power supply element conform to a predetermined proportional relationship. Through a reasonable parallel setting of power supply elements and an intelligent power supply control strategy, the power of multiple power supply elements is fully utilized, avoiding power waste, effectively extending the battery life of the aerosol generating device, and meeting the user's demand for long-term use of the device.

[0079] Furthermore, the controller is connected to the first power supply element and the second power supply element, and can determine the power demand of the electrical load element according to the working stage of the aerosol generating device and the proportional relationship between the capacity of the second power supply element and the capacity of the first power supply element. Dynamically adjust the power supply mode according to the power demand of the electrical load element, and control at least one of the first power supply element and the second power supply element to supply power to the electrical load element. According to different operating stages of the aerosol generating device and the capacity ratio relationship of the power supply elements, flexibly adjust the power supply mode, so that the aerosol generating device can better adapt to various complex usage scenarios and special requirements, improving the adaptability and flexibility of the aerosol generating device. In addition, reasonable power supply control reduces equipment failures caused by power problems, such as avoiding situations such as over-discharge or insufficient power supply of the power supply element, ensuring that the electrical load element can stably obtain power supply, thereby enhancing the performance stability and reliability of the aerosol generating device.

[0080] It should be understood that when the capacity of the second power supply element and the first power supply element satisfy different proportional relationships, it indicates that the importance of the two power supply elements in the power supply system is different. Therefore, it is necessary to set different voltage thresholds (a first voltage threshold and a second voltage threshold, and the second voltage threshold is greater than the first voltage threshold) according to different proportional relationships, thereby determining the power supply capacity of the first power supply element and controlling the output power of the power supply accordingly to meet the power output demand of the electrical load element.

[0081] In one implementation, the controller is further configured to, if the capacity of the second power supply element and the capacity of the first power supply element satisfy a first proportional relationship, control at least one of the first power supply element and the second power supply element to supply power to the electrical load element according to the operating stage of the aerosol generating device and the comparison result between the voltage value of the first power supply element and the first voltage threshold.

[0082] In one implementation, the controller is further configured to, if the capacity of the second power supply element and the capacity of the first power supply element satisfy a second proportional relationship, control at least one of the first power supply element and the second power supply element to supply power to the electrical load element according to the operating stage of the aerosol generating device and the comparison result between the voltage value of the first power supply element and the second voltage threshold.

[0083] Wherein, the second voltage threshold is greater than the first voltage threshold.

[0084] In some examples, if the capacity of the second power supply element and the capacity of the first power supply element satisfy a first proportional relationship, the controller continuously monitors the voltage value of the first power supply element and compares the voltage value of the first power supply element with the first voltage threshold. Further, according to the operating stage of the aerosol generating device and the comparison result between the voltage value of the first power supply element and the first voltage threshold, control at least one of the first power supply element and the second power supply element to supply power to the electrical load element.

[0085] In some examples, when the capacity of the second power supply element and the capacity of the first power supply element satisfy a second proportional relationship, since the second voltage threshold is relatively high, that is, the second voltage threshold is greater than the first voltage threshold (for example, the first voltage threshold is 3.55V and the second voltage threshold is 3.70V, etc.). Therefore, in this case, the power requirement for the first power supply element is more stringent. The controller also monitors the voltage value of the first power supply element and compares the voltage value of the first power supply element with the second voltage threshold. Further, according to the operating stage of the aerosol generating device and the comparison result between the voltage value of the first power supply element and the second voltage threshold, control at least one of the first power supply element and the second power supply element to supply power to the electrical load element.

[0086] By setting different voltage thresholds according to different capacity proportional relationships, the controller can accurately determine the power supply capacity of the first power supply element, thereby flexibly adjusting the power supply strategy. In this way, it can be ensured that the electrical load element can obtain a stable power supply under various conditions, improving the performance and reliability of the aerosol generating device. Dynamically adjusting the power supply mode according to the operating stage of the aerosol generating device and the actual power of the power supply element can make full use of the power of each power supply element and avoid energy waste. On the premise of meeting the requirements of the electrical load element, the power supply efficiency is improved.

[0087] Moreover, a reasonable power supply control strategy can prevent the power supply element from being over-discharged or over-charged, reducing damage to the power supply element. For example, when the first power supply element has sufficient power, it is preferentially used to avoid prematurely enabling the second power supply element; when the power of the first power supply element is insufficient, the power supply mode is switched in time to prevent the first power supply element from being over-discharged, which helps to extend the service life of the two power supply elements and reduce the maintenance cost of the aerosol generating device.

[0088] In one possible implementation, as Figure 2 shown, the controller is further configured to perform the following method steps:

[0089] S201, if the capacity of the second power supply element and the capacity of the first power supply element satisfy a first proportional relationship, then when a preheating instruction is received, detect whether the voltage value of the first power supply element is higher than a first voltage threshold.

[0090] S202, if it is detected that the voltage value of the first power supply element is higher than the first voltage threshold, then when the operation stage is the preheating stage, control the first power supply element and the second power supply element to provide electrical energy for the electrical load element.

[0091] S203, when the operation stage is not the preheating stage, control the first power supply element to provide electrical energy for the electrical load element.

[0092] In some examples, the preheating instruction can be a signal triggered by a user operation or automatically determined by the device to enter the preheating stage. The first voltage threshold is a preset standard voltage value. For example, it can be 3.55V, which is used to measure whether the power of the first power supply element is sufficient to support subsequent power supply operations.

[0093] It should be understood that in the examples of the present application, when the capacity of the second power supply element and the capacity of the first power supply element satisfy a first proportional relationship (for example, 20%-30%, 10%-35%), once the controller detects that the aerosol generating device has received a preheating instruction, the controller immediately detects the voltage value of the first power supply element and compares the voltage value of the first power supply element with the first voltage threshold. If it is detected that the voltage value of the first power supply element is higher than the first voltage threshold, it indicates that the power of the first power supply element is relatively sufficient.

[0094] In some examples, when the operation stage of the aerosol generating device is the preheating stage, the electrical load element (such as a heating element) usually requires a relatively large output power to quickly increase the temperature to effectively heat the aerosol generating substrate. Therefore, the controller can control the first power supply element and the second power supply element to jointly provide electrical energy for the electrical load element. By using two power supply elements in parallel to supply power to the electrical load element, a larger current can be provided, thereby meeting the high-power requirements of the aerosol generating device in the preheating stage, ensuring that the aerosol generating device can quickly reach the target operating temperature, and then generating aerosol.

[0095] In some examples, when the aerosol generating device completes preheating and enters the non-preheating stage from the preheating stage, the power demand of the electrical load element relatively decreases. Therefore, the controller adjusts the power supply strategy and only controls the first power supply element to supply electrical energy to the electrical load element. Since when the aerosol generating device is in the non-preheating stage, the power supply of the first power supply element alone can meet the power demand of the electrical load element, the second power supply element is in a standby state, which can reduce unnecessary energy consumption, extend the service life of the second power supply element, and also helps to improve the power supply efficiency of the aerosol generating device.

[0096] Through the examples of the present application, when the aerosol generating device is in the preheating stage, the two power supply elements jointly supply power to the electrical load element, which can quickly respond to the high power demand of the electrical load element, enable the device to quickly reach the working state, and improve the user experience. When the aerosol generating device is in the non-preheating stage, only the first power supply element is used for power supply, which can not only meet the low power demand of the electrical load element, but also avoid excessive discharge of the second power supply element when it is not necessary, save energy, and realize flexible adjustment of the power supply mode according to the characteristics of different working stages of the aerosol generating device.

[0097] Furthermore, the examples of the present application accurately control the power supply according to the voltage state of the power supply element and the device working stage, which can ensure that the electrical load element always obtains a stable power supply, reduce device failures caused by insufficient or unstable power supply, and improve the overall stability and reliability of the aerosol generating device.

[0098] In a possible implementation, still as Figure 2 shown, the controller is further configured to perform the following method steps:

[0099] S204, if it is detected that the voltage value of the first power supply element is higher than the first voltage threshold and the operation stage is the standby stage, control the voltage value of the first power supply element to be equal to the voltage value of the second power supply element.

[0100] In some examples, during the use of the aerosol generating device, the charging and discharging conditions of the two power supply elements are different, resulting in a voltage difference between the two power supply elements. Moreover, voltage imbalance will affect the overall performance and life of the power supply system (power system). Therefore, when the capacity of the second power supply element and the capacity of the first power supply element satisfy the first proportional relationship, and it is detected that the voltage value of the first power supply element is higher than the first voltage threshold, and at the same time the operation stage of the aerosol generating device is the standby stage, the controller starts the voltage equalization operation.

[0101] In some examples, the controller may continuously monitor the voltage values of the first power supply element and the second power supply element. When the aerosol generating device is in the standby stage, when it is determined that the voltage of the first power supply element is higher than the first voltage threshold, the voltage difference between the two power supply elements is started to be monitored. In an alternative example, the controller controls the switching element in the control circuit to establish a charging circuit between the first power supply element and the second power supply element. Since the voltage value of the first power supply element is relatively high, the current will flow from the first power supply element to the second power supply element, charging the second power supply element, and the voltage value of the second power supply element will gradually increase.

[0102] During the charging process, the controller monitors the voltage changes of the two power supply elements in real time. When it is detected that the voltage difference between the two shrinks to a predetermined equalization range, the controller adjusts the parameters of the charging circuit to reduce the charging current until the voltage values of the first power supply element and the second power supply element are basically equal, completing the voltage equalization operation.

[0103] Through the examples of the present application, if it is detected that the voltage value of the first power supply element is higher than the first voltage threshold and the operation stage is the standby stage, the voltage value of the first power supply element is controlled to be equal to the voltage value of the second power supply element. The equalized voltage state helps to reduce the stress and loss inside the power supply element, delay the battery aging speed, extend the service life of the first power supply element and the second power supply element, enable the two power supply elements to work more cooperatively in subsequent operations, and avoid over-discharging or insufficient charging of a certain power supply element due to voltage differences, thereby improving the overall output stability and efficiency of the power supply system.

[0104] In one possible implementation, still as Figure 2 shown, the controller is further configured to perform the following method steps:

[0105] S205, if it is detected that the voltage value of the first power supply element is lower than the first voltage threshold, then control the aerosol generating device to output a charging prompt message and shut down.

[0106] It should be understood that when it is detected that the voltage value of the first power supply element is lower than the first voltage threshold, it indicates that the power of the first power supply element has dropped to a relatively low level. Continuing to use will cause over-discharge of the first power supply element, resulting in irreversible damage and inability to provide stable electrical energy for the aerosol generating device.

[0107] Therefore, the controller monitors the voltage value of the first power supply component in real time and compares the voltage value of the first power supply component with the first voltage threshold. When the voltage value of the first power supply component is lower than the first voltage threshold, corresponding control operations are triggered. For example, the controller controls the prompting device in the aerosol generating device to output a charging prompt message in various ways, such as a sound prompt (emitting a beep of a specific frequency), a light prompt (the indicator light flashing a specific color), or a text prompt displayed on the display screen (such as, "Please charge"), to remind the user to charge the first power supply component in a timely manner.

[0108] In some examples, simultaneously with or after outputting the charging prompt message, the controller can also control the aerosol generating device to perform a shutdown operation, cut off the power supply to the power-consuming load component, and avoid continuing to use the device when the power is extremely low, thus protecting the safety of the power supply component and the device.

[0109] Through the examples of the present application, over-discharge of the first power supply component can be avoided, the service life of the first power supply component can be extended, abnormal conditions or damage of the device caused by too low power of the power supply can be prevented, and the safety of the aerosol generating device during use can be ensured. Moreover, the timely charging prompt message enables the user to understand the power status of the device in advance, reasonably arrange the charging time, and avoid the inconvenience caused by sudden power-off of the device.

[0110] In a possible implementation manner, as Figure 3 shown, the controller is further configured to execute the following method steps:

[0111] S301, if the capacity of the second power supply component and the capacity of the first power supply component satisfy a second proportional relationship, then when a preheating instruction is received, detect whether the voltage value of the first power supply component is higher than a second voltage threshold;

[0112] S302, if it is detected that the voltage value of the first power supply component is lower than the second voltage threshold, then when the operation stage is the preheating stage and the non-preheating stage, control the first power supply component to provide electrical energy for the power-consuming load component.

[0113] S303, when the operation stage is the standby stage, control the voltage value of the first power supply component and the voltage value of the second power supply component to reach equilibrium.

[0114] Wherein, after controlling the voltage value of the first power supply component and the voltage value of the second power supply component to reach equilibrium, execute step S201. When a preheating instruction is received, detect whether the voltage value of the first power supply component is higher than the first voltage threshold, and then, according to the comparison result between the voltage value of the first power supply component and the first voltage threshold, control at least one of the first power supply component and the second power supply component to provide electrical energy for the power-consuming load component.

[0115] In some examples, when the capacity of the second power supply element and the capacity of the first power supply element satisfy a second proportional relationship (for example, the capacity of the second power supply element can be set to 5%-10%, 8%-15%, etc. of the capacity of the first power supply element), the power supply system enters a specific power supply management mode. Once the controller detects that the aerosol generating device has received a preheating instruction, the controller first detects whether the voltage value of the first power supply element is higher than a second voltage threshold (for example, the second voltage threshold is 3.70V).

[0116] In some examples, if the voltage value of the first power supply element is lower than the second voltage threshold, it indicates that the power of the first power supply element is relatively insufficient, but it still has the ability to supply power. When the aerosol generating device is in the preheating stage and the non-preheating stage, the controller controls the first power supply element to supply power to the electrical load element. This is considered that in this power situation, giving priority to using the first power supply element to supply power can, on the one hand, continue to consume the remaining power of the first power supply element, and on the other hand, avoid prematurely enabling the second power supply element to ensure that the second power supply element can play a role in subsequent high-power demand scenarios.

[0117] In some examples, when the aerosol generating device is in the standby stage, the power consumption demand of the aerosol generating device is in a very low state compared to the preheating stage and the non-preheating stage. At this time, the controller controls the voltage values of the first power supply element and the second power supply element to reach equilibrium. For example, through the circuit connection between the first power supply element and the second power supply element, the power supply element with relatively higher power charges the power supply element with relatively lower power until the voltage values of the first power supply element and the second power supply element tend to be the same, thereby improving the overall performance and stability of the power supply system.

[0118] In some examples, after the voltage equilibrium of the first power supply element and the second power supply element is completed, when the aerosol generating device receives a preheating instruction again, the controller will re-detect the voltage value of the first power supply element and compare the voltage value of the first power supply element with the first voltage threshold. According to the comparison result, the controller can adopt different power supply strategies:

[0119] In the first case, if the voltage value of the first power supply element is higher than the first voltage threshold: it indicates that the power of the first power supply element has increased after voltage equilibrium. At this time, according to the power demand of the electrical load element, it is possible to flexibly choose to let the first power supply element supply power alone, the second power supply element supply power alone, or both supply power together. For example, in the preheating stage, if the power demand is large, the first power supply element and the second power supply element supply power together to meet the requirement of rapid heating.

[0120] In the second case, if the voltage value of the first power supply component is lower than the first voltage threshold: it indicates that the power of the first power supply component is still insufficient. The controller can preferentially control the second power supply component to participate in power supply, or adjust the working mode of the electrical load component to reduce the power demand, ensuring that the aerosol generating device can operate normally.

[0121] In the examples of this application, by performing power supply control according to different capacity ratio relationships and voltage thresholds, the power of the first power supply component and the second power supply component can be more accurately allocated, avoiding unnecessary power waste. For example, when the power of the first power supply component is insufficient, the power supply timing of the first power supply component is reasonably determined, and voltage equalization is performed during the standby stage, improving the energy utilization rate of the power supply system.

[0122] Moreover, in the examples of this application, the power supply strategy is dynamically adjusted in different working stages and power supply states to ensure that the electrical load component can always obtain a stable power supply. Especially, after voltage equalization, power supply is controlled again according to the voltage situation, which can adapt to different power demands of the device and reduce device failures caused by power fluctuations. In addition, performing voltage equalization during the standby stage can reduce the voltage difference inside the power supply component, reduce the battery aging speed, thereby extending the service life of the first power supply component and the second power supply component, and reducing the maintenance cost of the device.

[0123] In a possible implementation, still as Figure 3 shown, the controller is further configured to perform the following method steps:

[0124] S304, if it is detected that the voltage value of the first power supply component is higher than the second voltage threshold, then in the case where the operation stage is the preheating stage and the non-preheating stage, control the first power supply component to provide electrical energy for the electrical load component.

[0125] S305, in the case where the operation stage is the standby stage, do not perform control operations and wait to receive a preheating instruction.

[0126] Wherein, in the case where S305 receives a preheating instruction, return to execute the operation of detecting whether the voltage value of the first power supply component is higher than the second voltage threshold in S301.

[0127] In some examples, when the controller detects that the voltage value of the first power supply component is higher than the second voltage threshold, this indicates that the power of the first power supply component is in a relatively sufficient state. Based on this state, the controller can adopt corresponding power supply control strategies according to different working stages of the aerosol generating device:

[0128] In one case, when the aerosol generating device is in the preheating stage and the non-preheating stage, the electrical load element requires a stable power supply to achieve the corresponding functions. Since the first power supply element has sufficient power, the controller can control only the first power supply element to supply power to the electrical load element, making full use of the power of the first power supply element, reducing the usage frequency of the second power supply element, thereby extending the service life of the second power supply element and also reducing the energy consumption of the device.

[0129] In another case, when the aerosol generating device is in the standby stage, the electrical load of the aerosol generating device is extremely low and hardly requires additional power consumption. At this time, the controller does not perform control operations, making the aerosol generating device in a low-power standby state, which helps to further reduce the energy consumption of the device, extend the battery life, and also reduce unnecessary circuit operations and the probability of device failures.

[0130] In some examples, when the operation stage is the standby stage, the controller enters a waiting state and continuously monitors whether a preheating instruction is received (for example, a signal triggered by a user operation indicating that the user has a need to use the device). If the controller detects that the device has received a preheating instruction, the controller can immediately detect whether the voltage value of the first power supply element is higher than the second voltage threshold. This is because during the standby process of the device, the first power supply element may have self-discharge phenomena or the voltage may change due to other factors. By detecting the voltage value of the first power supply element again, the controller can re-evaluate the power supply capacity of the first power supply element based on the latest power supply state, so as to determine a suitable power supply strategy to ensure that stable and sufficient power can be provided to the electrical load element during the preheating stage and ensure the normal start-up and preheating of the device.

[0131] Through the examples of the present application, when the first power supply element has sufficient power, only the first power supply element is used for power supply, avoiding unnecessary losses of the second power supply element and reducing the energy consumption of the power supply system. No additional control operations are performed during the standby stage, further reducing power consumption and extending the device's battery life. Moreover, after receiving a preheating instruction during the standby stage, the voltage value of the first power supply element is detected again, and the power supply strategy can be adjusted according to the real-time power supply state, enabling the aerosol generating device to quickly and stably enter the preheating stage under different power supply conditions, improving the flexibility and reliability of the aerosol generating device, and providing a better user experience for users.

[0132] In one possible implementation, as Figure 4 shown, the controller is further configured to perform the following method steps to replace S203:

[0133] S401, when the operation stage is in the non-preheating stage, after controlling the voltage value of the first power supply component to decrease to the third voltage threshold, electrical energy is provided to the electrical load component, where the third voltage threshold is less than the first voltage threshold.

[0134] In addition, as in Figure 5 steps S302 and S304, when the operation stage is in the non-preheating stage, the controller can first control the voltage value of the first power supply component to decrease to the third voltage threshold, and then control the first power supply component to provide electrical energy to the electrical load component.

[0135] In some examples, during the operation of the aerosol generating device, the non-preheating stage can be understood as the device being in a normal working state. At this time, the power demand of the electrical load component is relatively stable and lower than that in the preheating stage. The controller monitors the voltage of the first power supply component to determine the appropriate power supply timing.

[0136] In some examples, the third voltage threshold (for example, 2.3V, 2.5V, 2.8V, etc.) is less than the first voltage threshold (for example, 3.3V, 3.5V, 3.6V) to manage the use of power more precisely and give full play to the efficiency of the power supply system.

[0137] In an alternative example, when the operation stage of the aerosol generating device is in the non-preheating stage, the controller continuously monitors the voltage value of the first power supply component in real time through devices such as a voltage sensor connected to the power supply component, and compares the monitored voltage value of the first power supply component with the third voltage threshold. It should be understood that when the controller detects that the voltage value of the first power supply component decreases to be equal to or lower than the third voltage threshold, it indicates that the power of the first power supply component has dropped to a specific lower level (i.e., a predetermined ratio), and then the controller issues a control signal to control the first power supply component to start providing electrical energy to the electrical load component.

[0138] Adopting this implementation method, by setting a lower third voltage threshold and enabling a voltage reduction measure for the non-preheating stage, the first power supply component participates in power supply only when the power is relatively low. After voltage reduction, the output voltage value of the first power supply component is relatively low, and it can work at almost full load (work at a higher duty cycle) without frequently switching the power supply component, so as to increase the duty cycle of the load component, and further make full use of the energy of the power supply system and improve the power use efficiency.

[0139] It should be understood that frequent charging and discharging, as well as deep discharging, will accelerate the aging and performance degradation of power supply components. During the non-preheating stage, the power demand of the electrical load component is relatively stable and low. Therefore, after the voltage of the first power supply component drops to a predetermined ratio (lower than 20% of the power of the first power supply component), it can still provide a stable power supply for the load. By enabling a voltage reduction measure during the non-preheating stage, the usage frequency of the first power supply component and the possibility of deep discharging can be reduced, thereby helping to extend the service life of the first power supply component and reducing the cost and frequency of replacing the power supply.

[0140] In a possible implementation, the positive electrode terminal of the first power supply component is electrically connected to the positive electrode terminal of the second power supply component to form a positive electrode common connection point, and the negative electrode terminal of the first power supply component is electrically connected to the negative electrode terminal of the second power supply component to form a negative electrode common connection point; the positive electrode common connection point is connected to the positive electrode access end of the electrical load component via a wire, and the negative electrode common connection point is connected to the negative electrode access end of the electrical load component via a wire.

[0141] In some examples, the first power supply component and the second power supply component are connected in parallel, that is, the positive electrode terminals of the first power supply component and the second power supply component are connected to each other to form a positive electrode common connection point, and the negative electrode terminals are connected to each other to form a negative electrode common connection point. In a parallel circuit, the voltage across each power supply component is equal and is equal to the total voltage after parallel connection. Furthermore, the output voltages of the first power supply component and the second power supply component are kept consistent, providing a stable voltage environment for the electrical load component.

[0142] In some examples, the positive electrode common connection point is connected to the positive electrode access end of the electrical load component via a wire, and the negative electrode common connection point is connected to the negative electrode access end of the electrical load component via a wire. In this way, the first power supply component and the second power supply component are connected in parallel and supply power to the electrical load component as a whole. The current flows out from the positive electrode common connection point, passes through the electrical load component, and then flows back to the power supply from the negative electrode common connection point.

[0143] Through the above examples, after two power supply components are connected in parallel, they can jointly provide current for the electrical load component. According to the characteristics of a parallel circuit, the total current is equal to the sum of the branch currents. Therefore, when the electrical load component requires a large current, the first power supply component and the second power supply component can output current simultaneously to meet the load's demand. For example, during the preheating stage of an aerosol generating device, the heating element requires a large power to quickly increase the temperature. At this time, the power supply components connected in parallel can provide sufficient current, enabling the aerosol generating device to quickly reach the operating temperature.

[0144] In another example, if one of the multiple power supply components fails or runs out of power, the other power supply components can still continue to supply power to the electrical load components, improving the reliability and stability of the entire power supply system and reducing the risk of equipment downtime caused by a single power supply failure. For example, when the first power supply component fails, the second power supply component can supply power to the electrical load components alone to ensure the basic operation of the aerosol generating device.

[0145] In another example, in some cases, the two power supply components can supply power alternately or reasonably distribute the power supply tasks according to the load demand, avoiding excessive discharge or long-term high-load operation of a single power supply component. For example, when the power demand of the electrical load component is small, one power supply component can supply power while the other power supply component is in standby, thereby extending the service life of the power supply component.

[0146] In one possible implementation, the aerosol generating device further includes:

[0147] A first electronic switch, connected in series on the wire from the positive extreme of the first power supply component to the positive common connection point, for controlling the on / off of the circuit between the positive pole of the first power supply component and the positive common connection point.

[0148] A second electronic switch, connected in series on the wire from the positive extreme of the second power supply component to the positive common connection point, for controlling the on / off of the circuit between the positive pole of the second power supply component and the positive common connection point.

[0149] A third electronic switch, connected in series on the wire from the negative extreme of the first power supply component to the negative common connection point, for controlling the on / off of the circuit between the negative pole of the first power supply component and the negative common connection point.

[0150] A fourth electronic switch, connected in series on the wire from the negative extreme of the second power supply component to the negative common connection point, for controlling the on / off of the circuit between the negative pole of the second power supply component and the negative common connection point.

[0151] In one possible implementation, a controller is respectively connected to the first electronic switch, the second electronic switch, the third electronic switch, and the fourth electronic switch.

[0152] The controller is used to control the first power supply component and the second power supply component to provide electrical energy to the electrical load component by controlling the first electronic switch, the second electronic switch, the third electronic switch, and the fourth electronic switch to be all closed.

[0153] In one possible implementation, the controller is used to control the first power supply component to provide electrical energy to the electrical load component by controlling the first electronic switch and the third electronic switch to be closed, and controlling the second electronic switch and the fourth electronic switch to be open.

[0154] In some examples, in an aerosol generating device, in addition to the parallel connection of the first power supply element, the second power supply element and the electrical load element, a plurality of electronic switches can be introduced to precisely control the power supply situation of the power supply:

[0155] The first electronic switch: It is located on the wire from the positive extreme of the first power supply element to the positive common connection point. When the first electronic switch is closed, the positive pole of the first power supply element is conducted with the positive common connection point, allowing current to flow out from the positive pole of the first power supply element; when the first electronic switch is opened, the path between the positive pole of the first power supply element and the positive common connection point is cut off.

[0156] The second electronic switch: It is connected in series on the wire from the positive extreme of the second power supply element to the positive common connection point, and its function is to control the on-off of the circuit between the positive pole of the second power supply element and the positive common connection point.

[0157] The third electronic switch: It is connected on the wire from the negative extreme of the first power supply element to the negative common connection point, controlling the conduction and disconnection between the negative pole of the first power supply element and the negative common connection point to ensure that the current can flow back normally.

[0158] The fourth electronic switch: It is located on the wire from the negative extreme of the second power supply element to the negative common connection point, responsible for controlling the on-off of the circuit between the negative pole of the second power supply element and the negative common connection point.

[0159] In an alternative example, when the controller controls the first electronic switch, the second electronic switch, the third electronic switch, and the fourth electronic switch to be all closed, the positive and negative poles of the first power supply element and the second power supply element are respectively conducted with the positive common connection point and the negative common connection point. At this time, the two power supply elements are connected in parallel together to jointly provide electrical energy for the electrical load element. It should be noted that the above situation is applicable to the scenario where the electrical load element requires a relatively large power. For example, during the preheating stage of the aerosol generating device, the heating element needs to quickly heat up and requires a relatively large current to meet the high-power demand. The simultaneous power supply of the two power supply elements can provide sufficient energy, enabling the aerosol generating device to quickly reach the target operating temperature.

[0160] The controller controls the first electronic switch and the third electronic switch to be closed, and at the same time controls the second electronic switch and the fourth electronic switch to be opened. In this way, only the positive and negative poles of the first power supply element are conducted with the common connection point, forming a complete power supply loop, while the second power supply element is isolated from the circuit, and only the first power supply element provides electrical energy for the electrical load element.

[0161] It still needs to be noted that the above situation is applicable to the case where the power demand of the electrical load element is relatively low, or when the second power supply element has insufficient power and needs to be protected. In this way, the power of the first power supply element can be fully utilized, the usage frequency of the second power supply element can be reduced, and its service life can be extended.

[0162] By controlling different combinations of four electronic switches through a controller, multiple power supply modes can be achieved, including independent power supply by the first power supply element, independent power supply by the second power supply element (controlling the first and third electronic switches to be disconnected and the second and fourth electronic switches to be closed), and combined power supply by the two power supply elements. This flexibility enables the aerosol generating device to dynamically adjust the power supply mode according to different working states and power consumption requirements, improving energy utilization efficiency.

[0163] For example, when it is detected that the power of the second power supply element is low, the controller can timely disconnect the second and fourth electronic switches to isolate the second power supply element from the circuit, prevent the second power supply element from over-discharging, and extend the service life of the second power supply element. At the same time, when a certain power supply element fails, the corresponding electronic switch can be quickly cut off to avoid the failure from affecting the normal operation of the power supply system of the aerosol generating device.

[0164] The example of the present application provides an example of a control method for an aerosol generating device. Please refer to Figure 6 as shown Figure 6 which shows a schematic flowchart of a control method for an aerosol generating device provided by the present application. As an example but not a limitation, this method can be applied to or run in an aerosol generating device.

[0165] The aerosol generating device includes: a main body, in which a first power supply element, at least one second power supply element, and an electrical load element are arranged; wherein, the first power supply element and the second power supply element are connected in parallel, and the first power supply element and the second power supply element after parallel connection are connected to the electrical load element. The capacity of the second power supply element is smaller than the capacity of the first power supply element, and the capacity of the second power supply element and the capacity of the first power supply element conform to a predetermined proportional relationship. The method includes:

[0166] S601, obtaining the proportional relationship between the capacity of the second power supply element and the capacity of the first power supply element.

[0167] S602, determining the operation stage of the aerosol generating device.

[0168] S603, according to the operation stage of the aerosol generating device and the proportional relationship between the capacity of the second power supply element and the capacity of the first power supply element, controlling at least one of the first power supply element and the second power supply element to supply electrical energy to the electrical load element.

[0169] Optionally, the first power supply component described above is a battery, for example, a high-capacity battery; the second power supply component is a battery or a capacitor, for example, a low-capacity battery. For example, taking the second power supply component as a battery, the capacity of the second power supply component can be 5%-10%, 20%-30%, or 10%-35% of the capacity of the first power supply component, etc. The present application does not specifically limit the specific proportional value, as long as the capacity of the second power supply component is less than the capacity of the first power supply component, and the capacity of the second power supply component and the capacity of the first power supply component conform to a predetermined proportional relationship.

[0170] In some examples, the capacity of the second power supply component and the capacity of the first power supply component conform to a predetermined proportional relationship, and this predetermined proportional relationship means that the capacity of the second power supply component is below a predetermined percentage of the capacity of the first power supply component (for example, below 35%, and the capacity of the second power supply component does not exceed 35% of the capacity of the first power supply component).

[0171] In some examples, the positive electrode of the first power supply component and the positive electrode of the second power supply component can be connected to each other, and the negative electrode of the first power supply component and the negative electrode of the second power supply component can also be connected to each other to form a parallel structure. The above connection method makes the voltage values at both ends of the first power supply component and the second power supply component equal, and they can jointly supply power to the electrical load components in the aerosol generating device.

[0172] In some examples, the paralleled first power supply component and second power supply component are connected to the electrical load component to provide the required electrical energy for the electrical load component. Optionally, in the examples of the present application, the electrical load component can be a key component in the aerosol generating device for heating the aerosol matrix to generate aerosol, such as heating elements like heating bodies and heating wires.

[0173] In the examples of the present application, the controller is respectively connected to the first power supply component, the second power supply component, and the electrical load component. In some examples, the controller can monitor parameters such as the voltage, current, and power of the power supply component, as well as the working state of the electrical load component in real time through sensors in the aerosol generating device.

[0174] In some examples, the predetermined proportional relationship between the capacity of the second power supply component and the capacity of the first power supply component can be determined in advance according to the actual requirements of the aerosol generating device. For example, when the second power supply component is mainly used for auxiliary power supply, the capacity of the second power supply component can be set to 20%-30%, 10%-35%, etc. of the capacity of the first power supply component.

[0175] In some examples, the operating stages of the aerosol generating device include but are not limited to: a preheating stage, a non-preheating stage (normal working stage), and a standby stage.

[0176] In some examples, in the case of the preheating stage or other high-power stages of the aerosol generating device, if the capacity of the second power supply element and the capacity of the first power supply element satisfy a predetermined proportional relationship (for example, 20%-30%, 10%-35%), since the power demand of the electrical load element is relatively large, the controller controls the first power supply element and the second power supply element to supply power to the electrical load element simultaneously, so as to provide sufficient power to meet the requirements of the high-power load element, extend the battery life of the device, improve the flexibility of power supply, and avoid the situation that the electrical load element cannot be driven due to insufficient output power of a single power supply element.

[0177] For example, in the preheating stage of the aerosol generating device, electrical load elements such as the heating wire of the aerosol generating device require a large amount of power to quickly heat up. By controlling the first power supply element and the second power supply element to work together to supply power to the electrical load element, the normal startup of the aerosol generating device can be ensured.

[0178] In some examples, in the low-power stage when the aerosol generating device is operating normally, the controller can, according to the power level of the power supply element, preferentially let the first power supply element supply power to the electrical load element, while the second power supply element is in a standby state. When the power level of the first power supply element drops to a predetermined proportion (for example, below 20% of the power level of the first power supply element), the controller then enables the second power supply element to assist in power supply, or lets the second power supply element supply power alone, so as to make full use of the power of each power supply element, improve the overall battery life of the device, and avoid the situation that a part of the device cannot be utilized due to the exhaustion of the power of a single power supply element.

[0179] Through the control method example of the aerosol generating device provided by the application example, by setting the first power supply element and the second power supply element in parallel in the aerosol generating device, and the first power supply element and the second power supply element after parallel connection are connected to the electrical load element. Since the capacity of the second power supply element is smaller than the capacity of the first power supply element, and the capacity of the second power supply element and the capacity of the first power supply element conform to a predetermined proportional relationship, through reasonable parallel setting of the power supply elements and an intelligent power supply control strategy, the power of multiple power supply elements is fully utilized, power waste is avoided, the battery life of the aerosol generating device is effectively extended, and the user's demand for using the device for a long time is met.

[0180] Furthermore, the controller is connected to the first power supply element and the second power supply element. It can determine the power demand of the electrical load element according to the working stage of the aerosol generating device and the proportional relationship between the capacity of the second power supply element and the capacity of the first power supply element. It dynamically adjusts the power supply mode according to the power demand of the electrical load element, and controls at least one of the first power supply element and the second power supply element to supply power to the electrical load element. According to the different operating stages of the aerosol generating device and the capacity proportional relationship of the power supply elements, the power supply mode is flexibly adjusted, so that the aerosol generating device can better adapt to various complex usage scenarios and special requirements, and improve the adaptability and flexibility of the aerosol generating device.

[0181] In addition, reasonable power supply control reduces equipment failures caused by power problems, such as avoiding situations such as over-discharge or insufficient power supply of the power supply element, ensuring that the electrical load element can stably obtain power supply, thereby improving the performance stability and reliability of the aerosol generating device.

[0182] In a possible implementation manner, according to the operating stage of the aerosol generating device and the proportional relationship between the capacity of the second power supply element and the capacity of the first power supply element, controlling at least one of the first power supply element and the second power supply element to supply power to the electrical load element includes:

[0183] If the capacity ratio of the second power supply element to the first power supply element satisfies the first proportional relationship, then according to the operating stage of the aerosol generating device and the comparison result between the voltage value of the first power supply element and the first voltage threshold, control at least one of the first power supply element and the second power supply element to supply power to the electrical load element.

[0184] If the capacity ratio of the second power supply element to the first power supply element satisfies the second proportional relationship, then according to the operating stage of the aerosol generating device and the comparison result between the voltage value of the first power supply element and the second voltage threshold, control at least one of the first power supply element and the second power supply element to supply power to the electrical load element.

[0185] Wherein, the second voltage threshold is greater than the first voltage threshold.

[0186] In some examples, if the capacity ratio of the second power supply element to the first power supply element satisfies the first proportional relationship, the controller continuously monitors the voltage value of the first power supply element and compares the voltage value of the first power supply element with the first voltage threshold. Furthermore, according to the operating stage of the aerosol generating device and the comparison result between the voltage value of the first power supply element and the first voltage threshold, control at least one of the first power supply element and the second power supply element to supply power to the electrical load element.

[0187] In some examples, when the capacity of the second power supply element and the capacity of the first power supply element satisfy a second proportional relationship, due to the higher second voltage threshold, that is, the second voltage threshold is greater than the first voltage threshold (for example, the first voltage threshold is 3.55V and the second voltage threshold is 3.70V, etc.). In this case, the power requirement for the first power supply element is more stringent. The controller also monitors the voltage value of the first power supply element and compares the voltage value of the first power supply element with the second voltage threshold. Furthermore, according to the operating stage of the aerosol generating device and the comparison result between the voltage value of the first power supply element and the second voltage threshold, at least one of the first power supply element and the second power supply element is controlled to supply power to the electrical load element.

[0188] By setting different voltage thresholds according to different capacity proportional relationships, the controller can more accurately judge the power supply capacity of the first power supply element, thereby flexibly adjusting the power supply strategy. In this way, it can be ensured that the electrical load element can obtain a stable power supply under various circumstances, improving the performance and reliability of the aerosol generating device. Dynamically adjusting the power supply mode according to the operating stage of the aerosol generating device and the actual power of the power supply element can make full use of the power of each power supply element on the premise of meeting the requirements of the electrical load element.

[0189] Moreover, a reasonable power supply control strategy can avoid over-discharging or over-charging of the power supply element, reducing damage to the power supply element. For example, when the first power supply element has sufficient power, it is preferentially used to avoid enabling the second power supply element prematurely; when the power of the first power supply element is insufficient, the power supply mode is switched in time to prevent over-discharging of the first power supply element, which helps to extend the service life of the two power supply elements and reduce the maintenance cost of the aerosol generating device.
