Description

Technical Field

[0001] The present application relates to the technical field of aerosol generating devices, and particularly to an aerosol generating device, a control method thereof, and a storage medium. Background Art

[0002] An aerosol generating device is an electronic product that mimics traditional cigarettes, and at least includes a control module and an atomization module. The atomization module contains at least one heating element and an aerosol generating substrate that can generate aerosol when heated. The control module controls the heating element to heat according to a preset temperature curve so that the aerosol generating substrate is atomized to generate aerosol.

[0003] As a portable electronic device, the aerosol generating device is configured with a battery to provide the necessary energy for the device. When using the aerosol generating device, it is necessary to quickly heat up from zero to the starting value of the temperature curve at the initial stage of heating. During this process, the battery needs to provide a large output voltage / current for the heating element; when the temperature of the heating element reaches a certain value, the temperature change output by the heating element is not large, and at this time, the output voltage / current required by the battery is less than that at the initial stage of heating.

[0004] To shorten the waiting time at the initial stage of heating, a battery with strong discharge capacity and large output current is configured for the aerosol generating device to meet the high-power requirements of the heating element at the initial stage of heating. However, for the same volume, a battery with strong discharge capacity and large output current has the problem of reduced battery capacity, which will lead to a shortened single-charge usage time of the aerosol generating device. Therefore, there is a trade-off between high-power output and single-charge endurance of the battery, and it is impossible to meet the requirements simultaneously to provide a better experience for users.

The embodiments of the present application will be described below with reference to the accompanying drawings.

[0080] Figure 1 It is a schematic structural diagram of an aerosol generating device provided by an embodiment of the present application. As Figure 1 shown, the aerosol generating device provided by this embodiment at least includes an atomization module 110, a power supply module 120, and a control module 130.

[0081] The housing of the aerosol generating device encloses to form a receiving cavity, and the atomization module 110, the power supply module 120, and the control module 130 are all accommodated in this cavity. Among them, the power supply module 120 is respectively connected to the atomization module 110 and the control module 130, and is used to provide stable and safe voltage and current to the atomization module 110 and the control module 130. The atomization module 110 includes an aerosol generating matrix and a heating element for heating the aerosol generating matrix to generate aerosol. When the power supply module 120 provides electrical energy to the atomization module 110 under the control of the control module 130 and there is current passing through the heating element, the heating element converts electrical energy into heat energy, and transfers the heat to the aerosol generating matrix through direct contact or indirect contact, causing it to evaporate to form aerosol for the user to inhale. Common types of heating elements include heating wires, ceramic heating elements, etc. The heating wire is usually made of a metal material, such as a nickel-chromium alloy wire, which has characteristics such as high resistivity and high temperature resistance. When the current provided by the power supply module 120 passes through the heating wire, the heating wire will generate a large amount of heat. The ceramic heating element utilizes the high thermal conductivity and good insulation performance of the ceramic material, embeds the heating element in the ceramic matrix, and evenly generates heat when current passes through, and can quickly heat up.

[0082] In this embodiment, the power supply module 120 includes a first power source and a second power source. When the first power source is used for power supply, the first power source can output a first supply current. When the second power source is used for power supply, the second power source can output a second supply current, and the first supply current is greater than the second supply current. In the aerosol generating device, the first power source and the second power source are non-removable batteries, usually lithium-ion batteries. Lithium-ion batteries have advantages such as high energy density, long life, and low self-discharge rate.

[0083] In some embodiments, to satisfy that the first supply current output by the first power source is greater than the second supply current output by the second power source, the discharge capacity of the first power source is stronger than that of the second power source. The discharge capacity refers to the ability of a battery to release electrical energy per unit time, usually expressed by the discharge rate (C-rate) or the maximum continuous current. The maximum continuous current (A) = rated capacity (Ah) × discharge rate (C). For batteries of the same volume, one of the design goals of a battery with a strong discharge capacity is that it supports a larger current output. By optimizing the materials and structure of the battery, a higher discharge rate can be achieved under the same volume, thereby outputting a larger current.

[0084] In other embodiments, when ensuring that the first supply current output by the first power source is greater than the second supply current output by the second power source, that is, under the same volume, the discharge capacity of the first power source is stronger than that of the second power source, in some scenarios, it also means that the energy density of the first power source is greater than that of the second power source. The energy density refers to the electrical energy stored per unit mass or volume, divided into mass energy density (Wh / kg) and volume energy density (Wh / L). A battery with a high energy density may have the potential to provide a larger current. Without considering factors such as material stability and structural design that limit its discharge capacity, a battery with a large energy density will also output a relatively larger current.

[0085] In this embodiment, the power supply module 120 includes a first power source and a second power source. Then, when the aerosol generating device supplies power to the heating element of the atomizing module 110 through the first power source and the second power source, there can be multiple ways, such as the single power supply mode of the first power source or the second power source, the alternating combination power supply mode of the first power source and the second power source, and the hybrid power supply mode of single power supply and combined power supply.

[0086] In some embodiments, the multiple power supply modes at least include a first power supply mode and a second power supply mode. The first power supply mode is to supply power at least using the first power source, and the second power supply mode is to disconnect the first power source and supply power at least using the second power source.

[0087] In this embodiment, the control module 130 is further configured to determine the power supply mode of the heating element from multiple power supply modes during the heating process of the heating element, and / or switch between different power supply modes according to the output of the heating element and the preset switching conditions.

[0088] That is to say, while controlling the heating of the heating element, the control module 130 is also used to determine the power supply mode of the heating element from multiple power supply modes during the heating process, so that the heating element has sufficient input current (power) to heat up to the target temperature. In some scenarios, after determining the power supply mode of the heating element from multiple power supply modes, the control module 130 will further switch between multiple power supply modes according to the output of the heating element and preset switching conditions to adapt to the change of the target temperature during the heating process of the heating element. In other scenarios, the control module 130 can also directly switch between multiple power supply modes according to the output of the heating element and preset switching conditions to determine the power supply mode of the heating element.

[0089] In some embodiments, during the heating process of the heating element, when the control module 130 switches between different power supply modes according to the preset switching conditions, it is based on the output current of the heating element at the current moment during the heating process. Specifically, when the output current of the heating element at the current moment is greater than or equal to the first threshold, the power supply mode of the heating element is switched to the first power supply mode; when the output current of the heating element at the current moment is less than the first threshold, the power supply mode of the heating element is switched to the second power supply mode, that is, it switches between the first power supply mode and the second power supply mode.

[0090] It can be understood that during the heating process of the heating element, the control module 130 will monitor the output current of the heating element. When the output current of the heating element at the current moment is greater than or equal to the first threshold, the power supply mode of the heating element is switched to the first power supply mode, that is, at least the first power supply is used to supply power to the heating element. On the contrary, when the output current of the heating element at the current moment is less than the first threshold, the power supply mode of the heating element is switched to the second power supply mode, that is, the first power supply is first disconnected, and at least the second power supply is used to supply power to the heating element.

[0091] In some embodiments, the control module 130 is further used to, after the aerosol generating device responds to the power-on instruction, enter the preheating stage and determine the power supply mode of the heating element as the first power supply mode.

[0092] After receiving the power-on instruction from the user or detecting the user's sucking action, the control module 130 of a common aerosol generating device starts to control the heating element to heat according to a pre-set temperature control curve, so that the aerosol generating matrix is heated and evaporated to generate aerosol. In some scenarios, the pre-set temperature control curve divides a single heating cycle into two stages, namely the preheating stage and the heating stage.

[0093] In the preheating stage, the heating element needs to reach a relatively high temperature within a short period of time. For example, it needs to reach 260 °C within 5 s, which means that a relatively large input power (voltage) needs to be provided to the heating element during the preheating stage. That is, a power supply with strong discharge capacity and large discharge current is required for power supply. That is, in this embodiment, after the aerosol generating device responds to the power-on instruction, the control module 130 controls the aerosol device to enter the preheating stage. At this time, the power supply mode of the heating element is determined to be the first power supply mode using the first power supply with a relatively large output current, so that the heating element reaches the preheating temperature within a short period of time, shortening the waiting time of the user and providing a better experience for them.

[0094] The heating stage comes after the preheating stage. At this time, the heating element continues to heat up at the preheating temperature according to the pre-set temperature control curve, but the heating-up process becomes slow. Even in some scenarios, combined with the user's puffing habit, there is also a process of temperature decrease in a short period of time. That is to say, during the heating stage, the temperature of the heating element rises or falls within a certain range, and thus there is no need to provide a relatively large input power (voltage) to the heating element, as long as the provided input power (voltage) can make the temperature of the heating element change according to the target temperature corresponding to the temperature control curve.

[0095] Therefore, in some embodiments, after the preheating is completed in the preheating stage, the power supply mode of the heating element is switched from the first power supply mode using the first power supply to the second power supply mode using the second power supply.

[0096] In other embodiments, during the heating stage, the control module 130 still monitors the output current of the heating element. When the output current of the heating element at the current moment is greater than or equal to the first threshold, the power supply mode of the heating element is switched to the first power supply mode, that is, at least the first power supply is used to supply power to the heating element. Conversely, when the output current of the heating element at the current moment is less than the first threshold, the power supply mode of the heating element is switched to the second power supply mode, that is, the first power supply is first disconnected, and at least the second power supply is used to supply power to the heating element. That is to say, during the preheating stage, a power supply with a relatively large input current is used for power supply; during the heating stage, further based on the output current of the heating element, when large current (power) output is not required, a power supply with a relatively small input current is used for power supply, and when large current (power) output is required, a power supply with a relatively large input current is used for power supply. That is, during the heating stage, the power supply mode is switched between the first power supply mode and the second power supply mode based on the preset switching conditions. In different stages, multiple power supply modes are used to supply power to the heating element, so that it has good temperature performance and provides a high-quality puffing taste for the user.

[0097] In summary, the aerosol generating device provided in this embodiment includes an atomization module, a power supply module, and a control module. The atomization module includes an aerosol generating substrate and a heating element for heating the aerosol generating substrate to generate aerosol. The power supply module includes a first power supply and a second power supply, and the current output by the first power supply is greater than the first supply current of the current output by the second power supply. When the control module controls the heating element to heat the aerosol generating substrate, it is further configured to determine the power supply mode of the heating element from multiple power supply modes during the heating process of the heating element, and / or switch between different power supply modes according to the output of the heating element and a preset switching condition. Among them, the multiple power supply modes at least include a first power supply mode in which at least the first power supply is used for power supply, and a second power supply mode in which the first power supply is disconnected and at least the second power supply is used for power supply. In this embodiment, by providing two power supplies with different output currents for the heating element in the aerosol generating device, it is realized that a power supply with a large current output is selected for power supply at the initial stage of heating the heating element and when high-power output is required, and a power supply with a small current output is selected for power supply when low-power output is required. The configuration of the dual batteries can take into account the high-power output of the aerosol generating device and the extension of the single-charge battery life cycle, providing the best experience for users.

[0099] Based on any of the above embodiments, the power supply module 120 of the aerosol generating device provided in this embodiment further includes a third power supply, and the third power supply can output a third supply current, and the third supply current is less than the second supply current. That is to say, the power supply module 120 is configured with three power supplies with different output currents, and the output current magnitudes decrease in sequence. After introducing the third power supply, a third power supply mode is also provided, that is, the multiple power supply modes include a first power supply mode, a second power supply mode, and a third power supply mode. Among them, the first power supply mode is at least using the first power supply for power supply, the second power supply mode is disconnecting the first power supply and at least using the second power supply for power supply, and the third power supply mode is disconnecting the first power supply and the second power supply and using the third power supply for power supply.

[0100] In some embodiments, when the control module 130 switches between different power supply modes according to the output of the heating element and the preset switching conditions, based on the current output current of the heating element, when the output current of the heating element at the current moment is greater than or equal to the first threshold, the power supply mode of the heating element is switched to the first power supply mode; when the output current of the heating element at the current moment is less than the first threshold, the power supply mode of the heating element is switched to the second power supply mode, that is, based on the current output current of the heating element, the power supply mode of the heating element is switched between the first power supply mode and the second power supply mode. At this time, the second power supply mode is at least powered by the second power supply, that is, the second power supply mode can be powered by the second power supply alone, or can be jointly powered by the second power supply and the third power supply.

[0101] In other embodiments, when the control module 130 switches between different power supply modes according to the output of the heating element and the preset switching conditions, based on the current output current of the heating element, when the output current of the heating element at the current moment is greater than or equal to the first threshold, the power supply mode of the heating element is switched to the second power supply mode; when the output current of the heating element at the current moment is less than the first threshold, the power supply mode of the heating element is switched to the third power supply mode, that is, based on the current output current of the heating element, the power supply mode of the heating element is switched between the second power supply mode and the third power supply mode. At this time, the second power supply mode is also at least powered by the second power supply, that is, the second power supply mode can be powered by the second power supply alone, or can be jointly powered by the second power supply and the third power supply, and the third power supply mode is powered by the third power supply alone.

[0102] It can be understood that when the control module 130 switches between different power supply modes according to the output of the heating element and the preset switching conditions, when the output current of the heating element at the current moment is greater than or equal to the first threshold, that is, when a large current output is required, the first power supply mode powered by the first power supply or the second power supply mode powered by at least the second power supply can be selected; conversely, when the output of the heating element at the current moment is less than the first threshold, the second power supply mode powered by at least the second power supply or the third power supply mode powered by the third power supply can be selected. All in all, it is to select the power supply with a large current output when the heating element requires a high-power output, and select the power supply with a small current output when a low-power output is required.

[0103] In some embodiments, the control module 130 is further configured to, after the aerosol generating device responds to a power-on instruction, enter a preheating stage and determine the power supply mode of the heating element as the first power supply mode. After the aerosol generating device completes preheating, it switches between the second power supply mode and the third power supply mode according to the output of the heating element and a preset switching condition. Specifically, when the current output of the heating element is greater than or equal to a first threshold, the power supply mode of the heating element is switched to the second power supply mode; when the current output of the heating element is less than the first threshold, the power supply mode of the heating element is switched to the third power supply mode; wherein, the third power supply mode is to disconnect the first power supply and the second power supply and supply power using a third power supply.

[0104] It can be understood that when the aerosol generating device is in the preheating stage that requires rapid temperature rise and high-power output, the first power supply with the maximum output current is used for power supply. After completing preheating and entering the heating stage, according to the currently monitored output current of the heating element, the second power supply and / or the third power supply are selected for power supply. At this time, the second output current and the third output current output by the second power supply and the third power supply can be much smaller than the first output current.

[0105] In some other embodiments, the control module 130 is further configured to determine the power supply mode of the heating element as the third power supply mode when the aerosol generating device is in a low-power state; wherein, the low-power state includes the aerosol generating device entering a standby state or the output temperature of the heating element continuously decreasing within a preset time period.

[0106] It can be understood that when the aerosol generating device enters a standby state or the output temperature of the heating element continuously decreases within a preset time period, when the heating element of the aerosol generating device no longer continues to heat or does not need to maintain a large output temperature, the third power supply with the minimum output current can be used to supply power to the heating element.

[0107] Figure 3 FIG. is a schematic structural diagram of an aerosol generating device provided in another embodiment of the present application. As Figure 3 shown, the aerosol generating device provided in this embodiment includes at least one of an atomization module 110, a power supply module 120, a control module 130, a PID feedback module 140, and a driving module 150.

[0108] In this embodiment, the PID feedback module 140 is connected to the control module 130 and is used to assist the control module 130 in determining the output current of the heating element at the current moment. Specifically, the control module 130 first determines the output temperature of the heating element at the current moment according to the resistance value of the heating element at the current moment and its own temperature resistance coefficient. The heating element is a resistive component. When the heating element changes the same temperature, the degree of change in the resistance value of the heating element is directly proportional to the magnitude of its temperature coefficient. When determining the output temperature of the heating element at the current moment, based on the resistance value R0 of the heating element at the standard temperature and its temperature coefficient TCR of resistance value changing with temperature, the resistance value of the heating element can be calculated. Further, according to the resistance value of the heating element at the current moment and its own temperature resistance coefficient TCR, the output temperature of the heating element at the current moment can be obtained. The control module 130 inputs the determined output temperature of the heating element at the current moment into the PID feedback module 140. The PID feedback module 140 determines the output duty cycle of the heating element at the current moment, that is, the duty cycle of the power supply voltage, according to the output temperature of the heating element at the current moment and the target temperature at the current moment. Then, the determined output duty cycle of the heating element at the current moment is transmitted to the control module 130. Finally, the control module 130 determines the output current of the heating element at the current moment according to the output duty cycle of the heating element at the current moment, the power supply voltage at the current moment, and the resistance value, and uses it as the basis for judging and selecting the power supply mode of the heating element.

[0109] In some embodiments, the PID feedback module 140 and the control module 130 can be two independent hardware modules or integrated in the same microprocessor to achieve their technical effects.

[0110] In some embodiments, the driving module 150 includes switch circuits with the same number of power supplies as in the power supply module 120. Each switch circuit is connected between its corresponding power supply and the heating element and is used to conduct or disconnect the circuit connection between its corresponding power supply and the heating element. That is, the driving module 150 includes a first switch circuit, a second switch circuit, and / or a third switch circuit. The first switch circuit realizes the connection between the first power supply and the heating element, the second switch circuit realizes the connection between the second power supply and the heating element, and the switch circuit realizes the connection between the third power supply and the heating element.

[0111] Specifically, the first end of the first switch circuit is connected to the output end of the first power supply, the second end of the first switch circuit is connected to the power supply end of the heating element, and the control end of the first switch circuit is connected to the first drive output end of the control module 130; the first end of the second switch circuit is connected to the output end of the second power supply, the second end of the second switch circuit is connected to the power supply end of the heating element, and the control end of the second switch circuit is connected to the second drive output end of the control module 130; the first end of the third switch circuit is connected to the output end of the third power supply, the second end of the third switch circuit is connected to the power supply end of the heating element, and the control end of the third switch circuit is connected to the third drive output end of the control module 130.

[0112] When the control module 130 determines the power supply mode of the heating element, it will output a drive control signal to the control end of the switch circuit of the power supply corresponding to the determined power supply mode through its drive output end, so as to realize the connection between the power supply and the heating element. Specifically, when the control module 130 determines that the power supply mode of the heating element at the current moment is the first mode, it outputs a first drive control signal at least through its first drive output end to drive the first switch circuit to conduct, connecting the output end of the first power supply and the power supply end of the heating element. Similarly, when it is determined that the power supply mode of the heating element at the current moment is the second mode, it outputs a second drive control signal at least through its second drive output end to drive the second switch circuit to conduct, connecting the output end of the second power supply and the power supply end of the heating element; when the power supply mode of the heating element at the current moment is the third mode, it outputs a third drive control signal at least through its third drive output end to drive the third switch circuit to conduct, connecting the output end of the first three power supplies and the power supply end of the heating element.

[0113] In some embodiments, the switch circuit is any one of a field effect transistor, a triode, and a relay.

[0114] Figure 4 It is a flowchart of a control method for an aerosol generating device provided by an embodiment of the present application. As Figure 4 shown, the control method provided in this embodiment is applied to the aerosol generating device described in any of the above embodiments, which has at least a first power supply and a second power supply, and the first supply current output by the first power supply is greater than the second supply current output by the second power supply. The control method specifically includes the following steps:

[0115] Step S401: During the heating process of the heating element, determine the power supply mode of the heating element from multiple power supply modes; wherein, the multiple power supply modes at least include a first power supply mode and a second power supply mode. The first power supply mode is to supply power at least using the first power supply, and the second power supply mode is to disconnect the first power supply and supply power at least using the second power supply.

[0116] Step S402: Switch between different power supply modes according to the output of the heating element and a preset switching condition.

[0117] It is understandable that the control module 130 of the aerosol generating device or the processor in the control module 130, while controlling the heating element to heat, determines the power supply mode of the heating element from multiple power supply modes so that the heating element has sufficient input current (power) to heat up to the target temperature. After determining the power supply mode of the heating element from multiple power supply modes, the control module 130 will further switch between multiple power supply modes according to the output of the heating element and the preset switching conditions to adapt to the change of the target temperature during the heating process of the heating element.

[0118] Figure 5 It is a flowchart of the control method for the aerosol generating device provided in another embodiment of the present application. As Figure 5 shown, for the control method of the aerosol generating device provided in this embodiment, the above step S402, switching between different power supply modes according to the output of the heating element and the preset switching conditions, specifically includes the following steps:

[0119] Step S501, obtain the output current of the heating element at the current moment during the heating process.

[0120] Step S502, when the output current of the heating element at the current moment is greater than or equal to the first threshold, switch the power supply mode of the heating element to the first power supply mode; when the output current of the heating element at the current moment is less than the first threshold, switch the power supply mode of the heating element to the second power supply mode.

[0121] During the heating process of the heating element, when switching between different power supply modes according to the preset switching conditions, it is based on the output current of the heating element at the current moment monitored at a certain frequency during the heating process. Specifically, when the output current of the heating element at the current moment is greater than or equal to the first threshold, switch the power supply mode of the heating element to the first power supply mode; when the output current of the heating element at the current moment is less than the first threshold, switch the power supply mode of the heating element to the second power supply mode, that is, switch between the first power supply mode and the second power supply mode.

[0122] Figure 6 It is a flowchart of the control method for the aerosol generating device provided in another embodiment of the present application. As Figure 6 shown, for the control method of the aerosol generating device provided in this embodiment, the applied aerosol generating device further includes a third power supply in addition to the first power supply and the second power supply, wherein the third power supply can output a third supply current, and the third supply current is less than the second supply current. The control method specifically includes the following steps:

[0123] Step S601, when the aerosol generating device enters the preheating stage in response to the power-on instruction, determine the power supply mode of the heating element as the first power supply mode.

[0124] Step S602: When the aerosol generating device has completed preheating, switch between different power supply modes according to the output of the heating element and a preset switching condition.

[0125] After the control module 130 of a common aerosol generating device receives a power-on instruction from the user or detects the user's sucking action, it starts to control the heating element to heat according to a pre-set temperature control curve, so that the aerosol generating substrate is heated and evaporated to generate aerosol. A single heating cycle can be divided into two stages, namely a preheating stage and a heating stage.

[0126] In the preheating stage, the heating element needs to reach a relatively high temperature in a short time. For example, it reaches 260 °C within 5 s, which means that a relatively large input power (voltage) needs to be provided to the heating element in the preheating stage, that is, a power supply with strong discharge capacity and large discharge current is required for power supply. That is, in this embodiment, after the aerosol generating device responds to the power-on instruction, the control module 130 controls the aerosol device to enter the preheating stage. At this time, the power supply mode of the heating element is determined to be the first power supply mode powered by a first power supply with a relatively large output current.

[0127] The heating stage comes after the preheating stage. At this time, the heating element continues to heat at the preheating temperature according to the pre-set temperature control curve, but the heating and temperature rising process becomes slow. The temperature of the heating element rises or falls within a certain range, so there is no need to provide a relatively large input power (voltage) to the heating element, as long as the provided input power (voltage) can maintain the temperature of the heating element.

[0128] In some embodiments, Step S602: When the aerosol generating device has completed preheating, switch between different power supply modes according to the output of the heating element and a preset switching condition, including:

[0129] When the current output current of the heating element is greater than or equal to a first threshold, switch the power supply mode of the heating element to a second power supply mode; when the current output current of the heating element is less than the first threshold, switch the power supply mode of the heating element to a third power supply mode.

[0130] When the aerosol generating device has completed preheating, the input power (voltage) provided by the power supply module 120 only needs to keep the temperature of the heating element within a certain range. Based on this, further in the heating stage, according to the monitored output current of the heating element, when the output current of the heating element at the current moment is greater than or equal to the first threshold, the power supply mode of the heating element is switched to the second power supply mode; when the output current of the heating element at the current moment is less than the first threshold, the power supply mode of the heating element is switched to the third power supply mode, that is, according to the output current of the heating element at the current moment, the power supply mode of the heating element is switched between the second power supply mode and the third power supply mode. At this time, the second power supply mode also uses at least the second power supply, that is, the second power supply mode can be to use the second power supply alone, or to be jointly powered by the second power supply and the third power supply, and the third power supply mode is to use the third power supply alone.

[0131] That is to say, when the aerosol generating device is in the preheating stage that requires rapid temperature rise and high-power output, the first power supply with the maximum output current is used for power supply. After the preheating is completed and the heating stage is entered, according to the monitored current output of the heating element, the second power supply and / or the third power supply is selected for power supply. At this time, the second output current and the third output current output by the second power supply and the third power supply can be much smaller than the first output current.

[0132] In some embodiments, the control method further includes the following steps:

[0133] Step S603, when the aerosol generating device enters the low-power state, determine the power supply mode of the heating element as the third power supply mode; wherein, the third power supply mode is to disconnect the first power supply and the second power supply and use the third power supply for power supply; the low-power state includes that the aerosol generating device enters the standby state or the output temperature of the heating element continuously decreases within a preset time period.

[0134] Figure 7 This is a flowchart for determining the output current of the heating element provided by an embodiment of the present application. As Figure 7 shown, in any of the above embodiments, during the heating process, determining the power supply mode of the heating element from multiple power supply modes and switching between different power supply modes according to the preset switching conditions are all based on the output of the heating element. When determining the output of the heating element, it specifically includes the following steps:

[0135] Step S701, obtain the resistance value and the power supply voltage of the heating element at the current moment according to the preset frequency.

[0136] Step S702, determine the output temperature of the heating element at the current moment according to the resistance value of the heating element at the current moment and its own temperature resistance coefficient.

[0137] Step S703: Based on a preset PID algorithm, determine the output duty cycle at the current moment according to the output temperature and the target temperature of the heating element at the current moment.

[0138] Step S704: Determine the output current of the heating element at the current moment according to the output duty cycle, the supply voltage, and the resistance value of the heating element at the current moment.

[0139] The heating element is a resistive component. When the heating element changes by the same temperature, the degree of change in the resistance value of the heating element is directly proportional to the magnitude of its temperature coefficient. According to the resistance value of the heating element at the current moment and its own temperature-resistance coefficient, the output temperature of the heating element at the current moment can be calculated. Based on the preset PID algorithm and the difference between the output temperature and the target temperature of the heating element at the current moment, the output duty cycle at the current moment, that is, the duty cycle of the supply voltage, can be calculated. Finally, based on the output duty cycle, the supply voltage, and the resistance value of the heating element at the current moment, the output current of the heating element at the current moment is calculated, which is used as the basis for judging and selecting the power supply mode of the heating element.

[0140] The control method of the aerosol generating device provided in any of the above embodiments is the same as the manner implemented by the aforementioned aerosol generating device control module 130 and has the same technical effects. To avoid repetition, it will not be elaborated here.

[0141] Figure 8 This is a flowchart of the control method of the aerosol generating device provided in another embodiment of the present application. As Figure 8 shown, the control method provided in this embodiment is applied to the aerosol generating device described in any of the above embodiments, which at least has a first power supply and a second power supply, and the first supply current output by the first power supply is greater than the second supply current output by the second power supply. The control method specifically includes the following steps:

[0142] Step S801: In response to the power-on instruction, control the aerosol generating device to enter the preheating stage and determine the power supply mode of the heating element as the first power supply mode.

[0143] Step S802: After the aerosol generating device completes preheating and enters the heating stage, determine the power supply mode of the heating element as the second power supply mode.

[0144] Compared with the control method of the aerosol generating device provided in any of the above embodiments, which focuses on selecting multiple power supply modes and switching between multiple power supply modes, the control method provided in this embodiment focuses on using two different power supply modes in the heating stage and the preset stage. That is, in the preheating stage that requires a greater input power, the first power supply mode with the first power supply is used, and in the heating stage that does not require a large power input, the second power supply mode including at least the second power supply is used.

[0145] In some embodiments, step S802: after the aerosol generating device completes preheating and enters the heating stage, determining the power supply mode of the heating element as the second power supply mode specifically includes:

[0146] Step S8021: in the heating stage, obtaining the output current of the heating element at the current moment;

[0147] Step S8022: when the output current of the heating element at the current moment is greater than or equal to the first threshold, switching the power supply mode of the heating element from the second power supply mode to the first power supply mode; when the output current of the heating element at the current moment is less than the first threshold, keeping the power supply mode of the heating element as the second power supply mode.

[0148] Further, after the aerosol generating device completes preheating and enters the heating stage, and determines to supply power to the heating element in the second power supply mode, it is also possible to switch the second power supply mode to the first power supply mode according to the monitored output current of the heating element when a greater aerosol output is required, so as to meet the needs of users.

[0149] Figure 9 It is a flowchart of a control method for an aerosol generating device provided in another embodiment of the present application. As Figure 9 shown, for the control method of the aerosol generating device provided in this embodiment, the aerosol generating device to which it is applied further includes a third power supply in addition to the first power supply and the second power supply, wherein the third power supply can output a third supply current, and the third supply current is less than the second supply current.

[0150] Step S901: in response to a power-on instruction, controlling the aerosol generating device to enter the preheating stage and determining the power supply mode of the heating element as the first power supply mode.

[0151] Step S902: after the aerosol generating device completes preheating and enters the heating stage, determining the power supply mode of the heating element as the second power supply mode.

[0152] Step S903: obtaining the output current of the heating element at the current moment.

[0153] Step S904: when the output current of the heating element at the current moment is greater than or equal to the first threshold, keeping the power supply mode of the heating element as the second power supply mode; when the output current of the heating element at the current moment is less than the first threshold, switching the power supply mode of the heating element from the second power supply mode to the third power supply mode.

[0154] It can be understood that in the heating stage, even when a greater aerosol output is required, the input power required by the heating element is less than that in the preheating stage. Therefore, in the case of having a third power supply, the heating stage can be selected to switch between the second power supply mode with at least the second power supply and the third power supply mode with the third power supply.

[0155] The control method of the aerosol generating device provided in any of the above embodiments is the same as the manner implemented by the aforementioned aerosol generating device control module 130 and has the same technical effects. To avoid repetition, it will not be elaborated here.

[0156] In summary, the control method of the aerosol generating device provided in any of the above embodiments, based on the power supplies with different output currents in the aerosol generating device, realizes power supply by selecting the power supply with a large current output at the initial stage of heating the heating element and when high-power output is required, and selecting the power supply with a small current output when low-power output is required. The configuration of dual batteries can take into account the high-power output of the aerosol generating device and the extension of the single-charge endurance period, providing the best experience for users.
