[0034] See also Figure 1 and Figure 2 The present application provides an aerosol generating device 100. The aerosol generating device 100 includes a power system 10, a motion detection device 20 and a controller 30. The power system 10 includes at least one super capacitor 11 and at least one battery 12, and the power system 10 can operate in a plurality of switchable operating modes. The motion detection device 20 is used to detect the motion state of the aerosol generating device 100, and the motion state includes the motion state. The controller 30 is configured to control the charging / power supply object of at least one super capacitor 11 and / or at least one battery 12 based on the operating mode.

[0035] like Figure 1 As shown, in some embodiments, the aerosol generating device 100 can be used by a user to heat the aerosol generating article 200 inserted therein, and the aerosol generating article 200 contains an aerosol generating substrate, and when the aerosol generating substrate is heated to a predetermined temperature, an aerosol that can be consumed by the user is generated. In some embodiments, the aerosol generating device 100 further includes a heating system 40, and the heating system 40 includes at least one heating element 41, and the heating element 41 is used to heat the aerosol generating substrate, and the power system 10 can supply power to the heating element 41 so that the heating element 41 can generate heat. In one embodiment, the heating element 41 can heat the aerosol generating substrate, and the aerosol generating substrate does not burn.

[0036] The heating method of the heating element 41 can be convection, conduction, radiation or a combination thereof. The aerosol generating substrate can be a solid or liquid aerosol generating substrate. The aerosol generating substrate includes, but is not limited to, materials used for medical treatment, health preservation, health, and beauty purposes. For example, the aerosol generating substrate is a liquid medicine, oil, or the aerosol generating substrate is a plant material, such as a plant root, stem, leaf, flower, bud, seed, etc.

[0037] In the embodiments of this invention, only the power system 10 including a super capacitor 11 and a battery 12 is taken as an example for introduction. In other embodiments of the present application, the number of super capacitors 11 may also include 2, 3, 4 or more, which are not listed here; the number of batteries 12 may also include 2, 3, 4 or more, which are not listed here.

[0038] Please combine Figure 3 In some embodiments, the power system 10 can operate in at least the following operating modes, as well as switch operating modes. The operating modes include wake-up mode, preheating mode, constant temperature heating mode and standby mode. Among them, the standby mode and the wake-up mode belong to non-heating processes. In the standby mode and the wake-up mode, the battery 12 or the super capacitor 11 will not supply power to the heating element 41. The preheating mode and the constant temperature heating mode belong to the heating process. In the preheating mode and the constant temperature heating mode, the super capacitor 11 and the battery 12 respectively supply power to the heating element 41, so that the heating element 41 generates heat to heat the aerosol generation matrix.

[0039] In one operation process, the power system 10 enters the heating process from the non-heating process to heat the aerosol generating substrate at the beginning of the puff, and returns to the non-heating process from the heating process after the puff is finished. Specifically, for example, when the motion state is the action state, the power system 10 switches from the standby mode to the wake-up mode, and then enters the preheating mode and the constant temperature heating mode in sequence, and switches from the constant temperature heating mode to the standby mode after the puff is finished to end the heating.

[0040] Among them, in the process of the power system 10 entering the preheating mode and the constant temperature heating mode from the wake-up mode in sequence, it can selectively enter the first charging mode or the second charging mode according to the power status of the supercapacitor 11 and the battery 12, so as to replenish the power of the supercapacitor 11 and / or the battery 12 in time, and ensure that the power of the supercapacitor 11 and / or the battery 12 can support the preheating mode and the constant temperature heating mode to power the heating element 41.

[0041] In some embodiments, the battery 12 is a lithium battery 12 that can be repeatedly charged and discharged.

[0042] The supercapacitor 11 is a passive energy storage device that has the characteristics of high current charging and discharging of capacitors and the energy storage characteristics of batteries 12. In some embodiments, the supercapacitor 11 includes a hybrid supercapacitor 11, an asymmetric supercapacitor 11, a pseudo supercapacitor 11, a double-layer capacitor, etc., which are not limited here.

[0043] The controller 30 controls the charging / power supply objects of the super capacitor 11 and / or the battery 12, including controlling the super capacitor 11 to charge from the charging object, the super capacitor 11 to supply power to the charging object, the battery 12 to charge from the charging object, and the battery 12 to supply power to the charging object.

[0044] The power supply object of the battery 12 and the super capacitor 11 includes the heating element 41. That is, the controller 30 can control the battery 12 to supply power to the heating element 41, and the super capacitor 11 can also supply power to the heating element 41. The battery 12 and the super capacitor 11 can also supply power to each other. For example, the controller 30 can control the battery 12 to charge the super capacitor 11, and can also control the super capacitor 11 to charge the battery 12. Figure 2 As shown, in one embodiment, the aerosol generating device 100 includes a switch assembly, and the switch assembly includes switches Q1, Q3, and Q4. The controller can control only switch Q1 to be turned on, so that the battery 12 charges the super capacitor 11, control only switch Q3 to be turned on, so that the battery 12 supplies power to the heating element 41, and only switch Q4 to be turned on, so that the super capacitor 11 supplies power to the heating element 41.

[0045] Among them, the discharge rate of the supercapacitor 11 is higher than the discharge rate of the battery 12, that is, the discharge current of the supercapacitor 11 is greater than the discharge current of the battery 12. In other words, when the supercapacitor 11 is used to power the heating element 41, the heating rate of the heating element 41 is greater than the heating rate of the heating element 41 when the battery 12 is used to power the heating element 41. The increase in the heating rate of the heating element 41 can reduce the time the user waits for aerosol generation and improve the user experience.

[0046] In conventional aerosol generating devices, the battery 12 is often used to power the heating element 41. Compared with conventional aerosol generating devices, the aerosol generating device 100 of the present application can use the supercapacitor 11 to power the heating element 41 during the heating stage of the heating element 41, so as to increase the heating rate of the heating element 41, reduce the time for users to wait for aerosol generation, and improve user experience.

[0047] The supercapacitor 11 can store electrical energy, but the storage capacity of the supercapacitor 11 is low, while the battery 12 has a higher storage capacity and can provide power for multiple rounds of heating. When the aerosol generating device 100 is in an environment where it can be connected to an external power source, the external power source can be used as a charging object for the supercapacitor 11, that is, the controller 30 can control the supercapacitor 11 to charge from the external power source. In addition, the battery 12 can also be used as a charging object for the supercapacitor 11, that is, the controller 30 can control the battery 12 to charge the supercapacitor 11.

[0048] However, when the aerosol generating device 100 is in standby mode without heating, the power stored in the super capacitor 11 will be consumed. If the super capacitor 11 is charged in advance but is in standby mode for a long time without heating, more power will be consumed and wasted, and the battery life of the aerosol generating device 100 will also be reduced due to the power consumption of the super capacitor 11.

[0049] On the other hand, if the battery 12 is used to charge the supercapacitor 11 after the aerosol generating device 100 responds to the user's interactive operation, the electricity stored in the supercapacitor 11 can be used in time to power the heating element 41, so as to avoid the consumption of the electricity stored in the supercapacitor 11 due to standby. However, this method will increase a waiting time for the battery 12 to charge the supercapacitor 11 after the user performs an interactive operation.

[0050] Based on this, the aerosol generating device 100 of the present application includes a motion detection device 20, which is used to detect the motion state of the aerosol generating device 100, and the motion state is used to determine the use state of the aerosol generating device 100. Among them, the motion state of the aerosol generating device 100 includes a motion state. If the motion detection device 20 detects that the motion state of the aerosol generating device 100 is a motion state, then the aerosol generating device 100 is likely to be in a state of interaction with the user. There is a certain time between the user interacting with the aerosol generating device 100 and the user performing the interactive operation. During this time, the controller 30 controls the battery 12 to charge the supercapacitor 11, which can reduce the standby power consumption of the supercapacitor 11 on the one hand, and can make the supercapacitor 11 have a certain amount of power before the user performs the interactive operation on the other hand, so as to timely power the heating element 41 after the user performs the interactive operation, so that the aerosol generating device 100 quickly responds to the user's interactive operation to heat, and reduces the user's waiting time.

[0051] For example, the action state represents the interactive action of the aerosol generating device 100 being "picked up". After the aerosol generating device 100 is picked up, the user starts heating by the interactive operation of pressing the start button. When the aerosol generating device 100 is picked up, the controller 30 switches to the wake-up mode according to the motion state of the aerosol generating device 100 being the action state. In the wake-up mode, the controller 30 controls the battery 12 to charge the super capacitor 11, so that during the period from when the aerosol generating device 100 is picked up to when the user presses the start button, the battery 12 charges the super capacitor 11, so that the super capacitor 11 has a certain amount of electricity when the user presses the start button, and can promptly respond to the user's operation of pressing the start button to power the heating element 41.

[0052] Furthermore, the motion state of the aerosol generating device 100 may also include a static state. If the motion state is a static state, the aerosol generating device 100 is most likely in an unused state, that is, a state of not being heated. In this case, the supercapacitor 11 is not charged to avoid wasting electricity.

[0053] In summary, in the aerosol generating device 100 of the present application, the power system 10 includes at least one supercapacitor 11, and the supercapacitor 11 can be used as a power source for heating the aerosol generating device 100 to increase the heating rate of the aerosol generating device 100, speed up the time of generating aerosol, and reduce the waiting time of the user. Furthermore, the motion detection device 20 can detect the motion state of the aerosol generating device 100, and when the motion state is the motion state, the controller 30 switches to the wake-up mode. In the wake-up mode, the controller 30 controls the battery 12 to charge the supercapacitor 11. In this way, it can prevent the supercapacitor 11 from being charged too late and increasing the waiting time of the user, and avoid the loss of power caused by the supercapacitor 11 being charged too early.

[0054] See also Figure 1 and Figure 2 In some embodiments, the motion detection device 20 includes a combination of one or more devices such as a speedometer, an angular velocity meter, an accelerometer, a gyroscope, and a pressure sensor, and obtains the motion state of the aerosol generating device 100 by detecting parameters such as the speed, angular velocity, acceleration, posture, and pressure of the aerosol generating device 100. For example, the motion state of the aerosol generating device 100 is the state in which the aerosol generating device 100 is picked up. The motion detection device 20 includes a three-axis accelerometer and a pressure sensor. When the aerosol generating device 100 is picked up, the pressure and acceleration of the aerosol generating device 100 increase. Therefore, the motion state and the static state can be distinguished according to the three-axis acceleration and pressure of the aerosol generating device 100.

[0055] In some embodiments, the aerosol generating device 100 includes a microprocessor (MCU), and the motion detection device 20 and the controller 30 are integrated in the microprocessor. In other embodiments, the motion detection device 20 and the controller 30 can also be independently provided, which is not limited here.

[0056] See also Figure 3 and Figure 4In certain embodiments, the heating cycle of the aerosol generating device 100 for heating the aerosol generating substrate includes a heating stage and a constant temperature heating stage. Among them, the heating stage is a stage of rapidly increasing the temperature of the heating element 41, corresponding to the preheating mode of the aerosol generating device. In the preheating mode, the controller 30 is configured to control at least one supercapacitor 11 to supply power to at least one heating element 41 so as to heat the heating element 41 to a target temperature, which is a temperature sufficient for the aerosol generating substrate to generate an aerosol. The constant temperature heating stage is a stage of maintaining the heating element at a target temperature so that the aerosol generating substrate is continuously heated to generate an aerosol, corresponding to the preheating mode of the aerosol generating device. In the constant temperature mode, the controller 30 is configured to control at least one battery 12 to supply power to at least one heating element 41 so as to maintain the heating element 41 at a target temperature.

[0057] In the heating stage, the high discharge rate of the supercapacitor 11 can be used to quickly heat up the aerosol-generating matrix, shortening the time to start generating aerosols. The duration of the constant temperature heating stage is often longer than the duration of the heating stage, and in the constant temperature heating stage, the temperature of the heating element 41 has reached the target temperature and does not need to be heated quickly. The capacity of the supercapacitor 11 is limited and it is difficult to provide long-term power supply, while the capacity of the battery 12 is large and suitable for long-term power supply. Therefore, using the battery 12 to power the heating element 41 in the constant temperature heating stage can meet the demand for long-term aerosol generation.

[0058] Please combine Figure 5 , Figure 5 1 is a circuit diagram of a heating system 40 and a power system 10 in a certain embodiment. In the figure, H1 is a heating element 41, CAP is a terminal of a super capacitor 11, and BAT is a terminal of a battery 12. The power system 10 also includes four MOS switches: Q7, Q8, Q9, and Q10. The source, drain, and gate directions of the MOS switches are as follows: Figure 5 As shown, no further details are given here. Among them, the MOS switch Q7 is electrically connected to the heating element 41H1 and the positive terminal CAP+ of the super capacitor 11, respectively, and the MOS switch Q8 is electrically connected to the heating element 41H1 and the positive terminal BAT+ of the battery 12, respectively. In the preheating mode, the controller 30 controls the MOS switch Q7 to open, and controls the MOS switch Q8 to close, so as to control the super capacitor 11 to supply power to the heating element 41H1. In the constant temperature mode, the controller 30 controls the MOS switch Q7 to close, and controls the MOS switch Q8 to open, so as to control the battery 12 to supply power to the heating element 41H1.

[0059] In some embodiments, the controller 30 switches from the preheating mode to the constant temperature mode when a preset condition is met, wherein the preset condition may include that the running time of the preheating mode reaches a preset preheating time, the temperature of the heating element 41 reaches a target temperature, and the like.

[0060] In one embodiment, the duration of the heating stage can be preset, and after the controller 30 switches to the preheating mode, it switches to the constant temperature mode after a duration of the heating stage to enter the constant temperature heating stage. For example, the duration of the heating stage is T1, and the controller 30 switches to the preheating mode at time t1, then the controller 30 waits for T1 time from time t1 to switch to the constant temperature mode.

[0061] In another embodiment, the controller 30 switches from the preheating mode to the constant temperature mode according to the temperature of the heating element 41. For example, the aerosol generating device 100 further includes a thermometer, which is used to detect the temperature of the heating element 41. The controller 30 is electrically connected to the thermometer to obtain the temperature of the heating element 41. When the temperature of the heating element 41 reaches the target temperature, the controller 30 switches to operate in the constant temperature mode to avoid the aerosol generating substrate from being heated too high.

[0062] See also Figure 1 and Figure 2 In some embodiments, the aerosol generating device 100 includes an interactive system for generating a start signal based on the interactive signal. Figure 3 and Figure 4 The start signal is used to indicate switching from the wake-up mode to the preheating mode, that is, the aerosol generating device 100 starts heating. The controller 30 controls the power output of the power system 10 according to the start signal to provide power for the heating cycle. Figure 4 As shown, for example, the heating cycle starts from the temperature rise heating stage, corresponding to the preheating mode. Accordingly, when the controller 30 obtains the start signal, it switches from the wake-up mode to the preheating mode to enter the heating cycle.

[0063] In some embodiments, the interactive system includes at least one of a suction detection component, a button component, and a touch component. Correspondingly, the interactive signal can be triggered by the following interactive operations of the user on the aerosol generating device 100: suction operation, button operation, voice control operation, touch action, etc. For example, the interactive system includes a suction detection component, and an interactive signal is generated correspondingly when the suction detection component detects the user's suction operation. For another example, the interactive system includes a button component, and the instruction triggered by a button or a combination of multiple buttons in the button component is an instruction to enter a heating cycle, and an interactive signal is generated correspondingly when the button or button combination is triggered. For another example, the interactive system includes a touch component, and the touch component includes a touch panel. The user's touch operation on the touch panel includes a touch operation to enter a heating cycle, and an interactive signal is generated correspondingly after the touch operation input is recognized.

[0064] See also Figure 3 and Figure 4In some embodiments, the heating stage of a heating cycle requires at least a first preset value of power from the supercapacitor 11. If the power of the supercapacitor 11 is less than the first preset value, the power supply requirement of the heating stage may not be met. Therefore, before the self-wake-up mode is switched to the preheating mode, the power of the supercapacitor 11 can be detected to ensure that the preheating mode is entered when the power of the supercapacitor 11 is sufficient.

[0065] Please combine Figure 6 In some embodiments, the controller 30 obtains the first charge value of the supercapacitor 11 when the start signal is obtained, and switches from the wake-up mode to the preheating mode when the first charge value of the supercapacitor 11 is greater than or equal to the first preset value; or switches from the wake-up mode to the first charging mode when the first charge value of the supercapacitor 11 is less than the first preset value. In the first charging mode, the controller 30 is configured to: control the battery 12 to charge the supercapacitor 11 until the first charge value of the supercapacitor 11 is greater than or equal to the first preset value.

[0066] For example, when the user picks up the aerosol generating device 100, the motion state of the aerosol generating device 100 is the action state, the controller 30 switches to operate in the wake-up mode, and controls the battery 12 to charge the supercapacitor 11. The time for the battery 12 to charge the supercapacitor 11 depends on the time when the user makes an interactive action. If the first charge value of the supercapacitor 11 has reached the first preset value when the controller 30 obtains the start signal when the user makes an interactive action, the heating element 41 can be heated to the target temperature, so that the controller 30 can switch from the wake-up mode to the preheating mode; if the first charge value of the supercapacitor 11 has not reached the first preset value when the user makes an interactive action and the controller 30 obtains the start signal, it is necessary to control the battery 12 to charge the supercapacitor 11 until the first charge value of the supercapacitor 11 is greater than or equal to the first preset value, and then switch from the first charging mode to the preheating mode to ensure that the heating element 41 can be heated to the target temperature.

[0067] See also Figure 4 Furthermore, if the duration of the constant temperature heating phase of each heating cycle is fixed, or different heating cycles may have constant temperature heating phases of different durations, but the constant temperature heating phase has a fixed minimum heating time, then the minimum amount of electricity that the battery 12 needs to provide during the constant temperature heating phase can be determined.

[0068] In some embodiments, the battery 12 needs to provide at least a third preset value of power in the constant temperature heating stage. If the power of the battery 12 is less than the third preset value, it may not be able to meet the power supply of a constant temperature heating stage. The controller 30 can also obtain a second power value of the battery 12, and switch from the preheating mode to the constant temperature mode when the second power value of the battery 12 is greater than or equal to the third preset value.

[0069] Please combine Figure 7 , if the first power value of the supercapacitor 11 meets the power required for the heating stage, but the second power of the battery 12 does not meet the power required for the constant temperature heating stage, it still cannot meet the power supply demand of a heating cycle. If the second power value of the battery 12 is less than the third preset value, but after the heating element 41 reaches the target temperature, the supercapacitor 11 still has remaining power, then the supercapacitor 11 can be used to power the heating element 41, so that the heating element 41 is maintained at the target temperature to meet the heating demand of the constant temperature heating stage. In some embodiments, the multiple switchable operating modes also include an auxiliary power supply mode, and the controller 30 can switch from the preheating mode to the auxiliary power supply mode when the second power value of the battery 12 is less than the third preset value, and control the supercapacitor 11 to power the heating element 41 in the auxiliary power supply mode, so that the heating element 41 is maintained at the target temperature. That is to say, when the second power value of the battery 12 is less than the third preset value, the auxiliary power supply mode can be used instead of the constant temperature mode to power the heating element 41.

[0070] Furthermore, in certain embodiments, when the second power value of the battery 12 is less than a third preset value, the controller 30 switches from the preheating mode to the constant temperature mode, and controls the battery 12 to supply power to the heating element 41 in the constant temperature mode; when the power of the battery 12 is exhausted or the power of the battery 12 is less than a fourth preset value, the controller 30 switches from the constant temperature mode to the auxiliary power supply mode, and controls the supercapacitor 11 to continue supplying power to the heating element 41 in the auxiliary power supply mode.

[0071] Based on the first charging mode and the auxiliary power supply mode, both the super capacitor 11 and the battery 12 can supply power to the heating element 41 to maintain the heating element 41 at the target temperature. In this way, when one of the super capacitor 11 and the battery 12 cannot meet the power supply demand of the heating element 41 in the constant temperature heating stage, the other one is used to supply power to the heating element 41.

[0072] Furthermore, based on the above-mentioned first charging mode and auxiliary power supply mode, as long as the sum of the first charge value of the supercapacitor 11 and the second charge value of the battery 12 can meet the power supply requirement of the heating cycle, regardless of whether the first charge value of the supercapacitor 11 and the second charge value of the battery 12 reach the first preset value and the third preset value respectively, the power supply of the heating cycle can be completed.

[0073] If the sum of the first charge value of the supercapacitor 11 and the second charge value of the battery 12 cannot meet the power supply requirement of a heating cycle, the heating cycle should not be entered, and the supercapacitor 11 and / or the battery 12 need to be charged until the sum of the first charge value of the supercapacitor 11 and the second charge value of the battery 12 can meet the power supply requirement of a heating cycle.

[0074] Based on this, in some embodiments, the multiple switchable operating modes further include a second charging mode, in which the controller 30 controls the supercapacitor 11 or the battery 12 to charge from an external power source connectable to the aerosol generating device 100 until the sum of the first power value of the supercapacitor 11 and the second power value of the battery 12 is greater than or equal to a second preset value. The second preset value is the minimum power value required to meet the power supply demand of a heating cycle.

[0075] Please combine Figure 8 Accordingly, when the controller 30 obtains the start signal, it obtains the sum of the first charge value of the supercapacitor 11 and the second charge value of the battery 12, and switches to the preheating mode to enter the heating cycle when the sum of the first charge value of the supercapacitor 11 and the second charge value of the battery 12 is greater than or equal to the second preset value; or switches to the second charging mode when the sum of the first charge value of the supercapacitor 11 and the second charge value of the battery 12 is less than the second preset value.

[0076] In one embodiment, when the sum of the first power value of the supercapacitor 11 and the second power value of the battery 12 is less than the second preset value, a low power prompt signal is issued to remind the user to charge the supercapacitor 11 and / or the battery 12. For example, when the sum of the first power value of the supercapacitor 11 and the second power value of the battery 12 is less than the second preset value, the prompt light of the aerosol generating device 100 is turned on as a low power prompt signal.

[0077] See also Fig. 9 , Fig. 9 1 is a circuit diagram of a power system 10 in a certain embodiment. In the figure, CAP is the terminal of the super capacitor 11, BAT is the terminal of the battery 12, and USBIN is the external power input terminal. The power system 10 also includes at least 6 MOS switches: Q15, Q16, Q5, Q18, Q12, and Q13. The source, drain, and gate directions of the MOS switches are as follows: Fig. 9When charging with an external power source, if the controller 30 controls the MOS switches Q15, Q16, Q5, and Q18 to be turned on, and controls the MOS switches Q12 and Q13 to be turned off, the external power source can be controlled to charge the supercapacitor 11 first. If the controller 30 controls the MOS switches Q15, Q16, Q12, and Q13 to be turned on, and controls the MOS switches Q5 and Q18 to be turned off, the external power source can be controlled to charge the supercapacitor 11 first.

[0078] See also Figure 3 In summary, in the process of switching the controller 30 from the wake-up mode to the preheating mode and from the preheating mode to the constant temperature mode, the acquisition of the first power value of the supercapacitor 11, the acquisition of the second power value of the battery 12, and the acquisition of the total power values ​​of the supercapacitor 11 and the battery 12 are added. When the above power values ​​are lower than the preset power values, the corresponding charging mode is entered for charging to ensure that the power of the supercapacitor 11 and the battery 12 meets the power supply requirements of the preheating mode and the constant temperature mode.

[0079] In some embodiments, the controller 30 is configured to obtain the heating state of the heating element 41, and the heating state includes a heated state and a non-heated state. The motion detection device 20 is configured to detect the motion state of the aerosol generating device 100 when the heating state is a non-heated state. Accordingly, the motion detection device 20 does not detect the motion state of the aerosol generating device 100 when the heating state is a heated state.

[0080] See also Figure 4 , wherein the heating state of the heating element 41 is a heated state, indicating that the heating element 41 is in a heating cycle; correspondingly, the heating state of the heating element 41 is a non-heated state, indicating that the heating element 41 is not in a heating cycle. Figure 3 , the motion state of the aerosol generating device 100 is mainly used to determine whether to enter the wake-up mode, and the wake-up mode is not in the heating cycle. That is to say, when the heating element 41 is in the heating cycle, the switching between the preheating mode and the constant temperature mode, or the switching between the preheating mode and the auxiliary power supply mode, will not enter the wake-up mode. Only when the heating element 41 is not in the heating cycle, it is necessary to determine whether to enter the wake-up mode based on the motion state of the aerosol generating device 100. Therefore, the heating state of the heating element 41 can be obtained by the controller 30, so that the motion detection device 20 detects the motion state of the aerosol generating device 100 when the heating state is a non-heated state, and does not detect the motion state of the aerosol generating device 100 when the heating state is a heated state, thereby avoiding the motion detection device 20 from frequently detecting the motion state of the aerosol generating device 100 to save power consumption.

[0081] In some embodiments, the controller 30 can determine the heating state of the heating element 41 according to the power supply condition of the heating element 41. For example, when the super capacitor 11 and the battery 12 both supply power to the heating element 41, it is determined that the heating state of the heating element 41 is a non-heating state; and when the super capacitor 11 and / or the battery 12 supply power to the heating element 41, it is determined that the heating state of the heating element 41 is a heating state.

[0082] In some embodiments, the controller 30 can obtain the real-time temperature and temperature change rate of the heating element 41 , and determine whether the heating element 41 is heated based on the real-time temperature and temperature change rate of the heating element 41 to determine the heating state of the heating element 41 .
