[0001] This application claims priority to Chinese Patent Application No. 202310091736.3, entitled "AEROSOL GENERATION DEVICE, AND CONTROL METHOD AND CONTROL DEVICE THEREFOR" and filed on January 16, 2023, which is incorporated herein by reference in its entirety.TECHNICAL FIELD

[0002] This application relates to the field of vaporization devices, and in particular, to an aerosol generation device, and a control method and control device therefor.BACKGROUND

[0003] A working principle of an aerosol generation device is mainly to heat, through a vaporization means, a vaporization substrate in a heating-without-combustion manner, so that components of the vaporization substrate are vaporized and volatilized and puffed by a user, thereby achieving a puffing experience.

[0004] A conventional heating technology includes electromagnetic heating. A peripheral heating manner adopted for electromagnetic heating is that a tubular metal heating element accommodates a vaporization substrate, and produces heat after sensing an alternating magnetic field of a coil, to heat the vaporization substrate through heat conduction. In addition, according to the length of the vaporization substrate, single-section heating or two-section heating may be performed on the vaporization substrate. For example, in the technology of Application No. CN109843097A, which discloses an electromagnetic heating manner of two-section heating, an inductive heating arrangement includes two induction coils that are separately controlled, where when one induction coil works normally, the other induction coil stops working. This manner is prone to mutual interference between the two induction coils, resulting in large temperature fluctuations, which is adverse to temperature control.SUMMARY

[0010] In an embodiment, the processor is configured to control the switch-on time of the first switch and the switch-on time of the second switch, to enable the second electromagnetic heating circuit to work at the second power when the first electromagnetic heating circuit works at the first power or enable the first electromagnetic heating circuit to work at the second power when the second electromagnetic heating circuit works at the first power, where the switch-on time of the first switch or second switch corresponding to the first power is greater than the switch-on time of the second switch or first switch corresponding to the second power.

[0012] In an embodiment, the coil of the first electromagnetic heating circuit and the coil of the second electromagnetic heating circuit have the same winding direction.

[0013] In an embodiment, the coil of the first electromagnetic heating circuit and the coil of the second electromagnetic heating circuit have opposite winding directions.

[0014] In an embodiment, the second power is used for maintaining a current temperature state of the vaporization substrate.

[0015] According to a second aspect, this application further provides a temperature control method for an aerosol generation device. The method includes: controlling amounts of energy provided by a power supply component to a first electromagnetic heating circuit and a second electromagnetic heating circuit, to enable the second electromagnetic heating circuit to work at a second power when the first electromagnetic heating circuit works at a first power or enable the first electromagnetic heating circuit to work at a second power when the second electromagnetic heating circuit works at a first power, where the first power and the second power are not equal.

[0016] According to a third aspect, this application further provides a control device for an aerosol generation device.

In the foregoing manner, in this application, to achieve a target puffing effect, two electromagnetic heating circuits are separately controlled to work at the same time. One circuit works at the first power, and the other circuit works at the second power. That is, when one region of the vaporization substrate is heated at a high power, the other region maintains a current temperature state at a low power, so that the temperature of the vaporization substrate can be controlled within a preset temperature range more precisely, to achieve a target puffing effect. In addition, because the second power can maintain the current temperature state of the vaporization substrate, fluctuations of the temperature of the vaporization substrate in the entire heating process are small, so that the target temperature can be reached at a lower first power, which is conducive to precise temperature control, and reduces the power loss, thereby reducing the total power consumption of the system.BRIEF DESCRIPTION OF THE DRAWINGS

In the following description, many specific details are described for thorough understanding of this application. However, this application may be implemented in many other manners different from those described herein.

Therefore, such terms should not be construed as a limitation to this application.

[0021] In this application, unless explicitly specified or limited otherwise, the terms, such as "connect" and "fix", should be understood broadly, for example, which may be a fixed connection, a detachable connections, or an integral connection; or may be a mechanical connection or an electrical connection; or may be a direct connection, an indirect connection through an intermediary, or internal communication between two elements or mutual action relationship between two elements, unless otherwise specified explicitly.

[0022] It should be noted that if an element is referred to as "being fixed to" another element, the element may be directly on the another element, or an intervening element may be present. If an element is considered to be "connected to" another element, the element may be directly connected to the another element, or an intervening element may also be present. If the intervening element is present, the terms "above" and "below" and similar expressions used in this specification are only for purposes of illustration but not indicate a unique implementation.

[0023] In an embodiment of this application, an aerosol generation device is provided. As shown in FIG. 1, the aerosol generation device includes: a power supply component 110, a control component 120, a first electromagnetic heating circuit 130, and a second electromagnetic heating circuit 140. The electromagnetic heating circuit in this embodiment (that is, the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140) includes, but is not limited to, an LC series resonant circuit, an LC parallel resonant circuit, a single-tube parallel resonant circuit, a half-bridge series resonant circuit, a full-bridge series resonant circuit, a class E power amplifier resonant circuit, and the like. Accommodating spaces (not shown in the figure) are respectively formed in the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140. Specifically, the first electromagnetic heating circuit 130 forms a first accommodating space, and the second electromagnetic heating circuit 140 forms a second accommodating space. The two accommodating spaces are configured for placing a vaporization substrate. The first electromagnetic heating circuit 130 is configured to heat the vaporization substrate in the first accommodating space, and the second electromagnetic heating circuit 140 is configured to heat the vaporization substrate in the second accommodating space. It should be noted that the vaporization substrate in the first accommodating space and the vaporization substrate in the second accommodating space are the same vaporization substrate. That is, one part of the vaporization substrate is located in the first accommodating space, and the other part is located in the second accommodating space. In an example, the control component 120 is separately connected to the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140. The control component 120 is further connected to the power supply component 110.

[0024] The power supply component 110 is configured to provide energy to the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140. Similarly, the power supply component 110 further provides energy to the control component 120, to enable the control component 120, the first electromagnetic heating circuit 130, and the second electromagnetic heating circuit 140 to work normally. The first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140 heat, according to the received energy, the vaporization substrate passing through the accommodating spaces of the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140, to form an aerosol for a user to puff.

[0025] The control component 120 is configured to control amounts of energy provided by the power supply component 110 to the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140, to enable the second electromagnetic heating circuit 140 to work at a second power when the first electromagnetic heating circuit 130 works at a first power or enable the first electromagnetic heating circuit 130 to work at a second power when the second electromagnetic heating circuit 140 works at a first power, where the first power and the second power are not equal.

[0026] Specifically, in a control process, the control component 120 can control amounts of energy provided by the power supply component 110 to the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140, to enable the second electromagnetic heating circuit 140 to work at a second power when the first electromagnetic heating circuit 130 works at a first power or enable the first electromagnetic heating circuit 130 to work at a second power when the second electromagnetic heating circuit 140 works at a first power. It should be noted that the control component 120 can also independently control the first electromagnetic heating circuit 130 or the second electromagnetic heating circuit 140 to work.

[0027] It may be understood that, to enable the aerosol generation device to work normally, that is, to vaporize the vaporization substrate normally, a working power of one of the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140 is greater than or equal to the minimum vaporization power of the vaporization substrate, that is, one of the first power and the second power is greater than or equal to the minimum vaporization power of the vaporization substrate. The minimum vaporization power herein refers to a working power of a heating circuit corresponding to the minimum temperature at which the vaporization substrate can be normally vaporized. It should be noted that for different vaporization substrates, minimum vaporization powers corresponding to the vaporization substrates are also different. The first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140 both include a heating element and a coil. The heating element may sense a changing electromagnetic field and is made of a material that generates an induced eddy current. A temperature sensor capable of measuring the temperature is arranged on the surface of the heating element, to measure the temperature at a position corresponding to the heating element. The heating element is arranged in the changing electromagnetic field generated by the coil, and is partitioned into at least two main heating regions by a position at which the coil is arranged. The two heating regions can respectively heat different parts of the vaporization substrate.

[0028] Further, to avoid two heating circuits simultaneously working at high powers (that is, the two heating circuits simultaneously work at powers greater than the minimum vaporization power of the vaporization substrate) from leading to excessively large overall power consumption of the aerosol generation device. In a manner of performing heating by using two sections simultaneously, the two electromagnetic heating circuits can be controlled at proper temperatures respectively, thereby improving consistency between puffing effects of front and back sections. In this embodiment, the first power is greater than or equal to the minimum power for normal vaporization of the vaporization substrate in the aerosol generation device, and the second power is less than the minimum power and is greater than 0. Alternatively, the second power is greater than or equal to the minimum power for normal vaporization of the vaporization substrate in the aerosol generation device, and the first power is less than the minimum power and is greater than 0. That is, one of the first power and the second power is greater than or equal to the minimum vaporization power of the vaporization substrate, and the other is less than the minimum vaporization power of the vaporization substrate. Working is performed at a smaller power.

[0029] It may be understood that a sum of the first power and the second power is less than or equal to the maximum output power of the power supply component 110. The foregoing aerosol generation device includes: a power supply component, a control component, a first electromagnetic heating circuit, and a second electromagnetic heating circuit, where the first electromagnetic heating circuit forms a first accommodating space, the second electromagnetic heating circuit forms a second accommodating space, the first electromagnetic heating circuit is configured to heat a vaporization substrate in the first accommodating space, and the second electromagnetic heating circuit is configured to heat the vaporization substrate in the second accommodating space; the power supply component is configured to provide energy to the first electromagnetic heating circuit and the second electromagnetic heating circuit; and the control component is configured to control amounts of energy provided by the power supply component to the first electromagnetic heating circuit and the second electromagnetic heating circuit, to enable the second electromagnetic heating circuit to work at a second power when the first electromagnetic heating circuit works at a first power or enable the first electromagnetic heating circuit to work at a second power when the second electromagnetic heating circuit works at a first power, where the first power and the second power are not equal. In the foregoing manner, in this application, to achieve a target puffing effect, two electromagnetic heating circuits are separately controlled to work at the same time. One circuit works at the first power, and the other circuit works at the second power. That is, when one region of the vaporization substrate is heated at a high power, the other region maintains a current temperature state at a low power, so that the temperature of the vaporization substrate can be controlled within a preset temperature range more precisely, to achieve a target puffing effect. In addition, because the second power can maintain the current temperature state of the vaporization substrate, fluctuations of the temperature of the vaporization substrate in the entire heating process are small, so that the target temperature can be reached at a lower first power, which is conducive to precise temperature control, and reduces the power loss, thereby reducing the total power consumption of the system.

[0030] In an exemplary embodiment, as shown in FIG. 2, the control component 120 includes: a first switch 121, a second switch 122, and a processor 123. The first end of the first switch 121 is connected to the power supply component 110, the second end of the first switch 121 is connected to the first electromagnetic heating circuit 130, and the enable end of the first switch 121 is connected to the processor 123. The first end of the second switch 122 is connected to the power supply component 110, the second end of the second switch 122 is connected to the second electromagnetic heating circuit 140, and the enable end of the second switch 122 is connected to the processor 123.

[0031] In this embodiment, the first switch 121 and the second switch 122 may be MOS transistors, or may be switches of other types in specific implementations. The control component 120 is connected to the enable ends of the first switch 121 and the second switch 122. The control component 120 can control the first switch 121 and the second switch 122 to switch on or off, to achieve, within a unit cycle, the duration in which the power supply component 110 is connected to the first electromagnetic heating circuit 130 by the first switch 121 and the duration in which the power supply component 110 is connected to the second electromagnetic heating circuit 140 by the second switch 122, to control, within the unit cycle, the energy received by the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140, that is, control the working powers of the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140. Specifically, the on and off times of the first switch 121 are controlled, to control the first electromagnetic heating circuit 130 to work at the first power; and in addition, the switch-on and switch-off times of the second switch 122 are controlled, to control the second electromagnetic heating circuit 140 to work at the second power. Alternatively, the on and off times of the second switch 122 are controlled, to control the second electromagnetic heating circuit 140 to work at the first power; and in addition, the switch-on and switch-off times of the first switch 121 are controlled, to control the first electromagnetic heating circuit 130 to work at the second power. When the first electromagnetic heating circuit 130 works at the first power, the switch-on duration of the corresponding first switch 121 is greater than the switch-on duration of the second switch 122, or when the second electromagnetic heating circuit 140 works at the first power, the switch-on duration of the corresponding second switch 122 is greater than the switch-on duration of the first switch 121, thereby controlling the first power to be greater than the second power.

[0032] In another exemplary embodiment, as shown in FIG. 3, the first electromagnetic heating circuit 130 includes a first capacitor 131 and a first coil 132, and the second electromagnetic heating circuit 140 includes a second capacitor 141 and a second coil 142. The first capacitor 131 is connected in parallel to the first coil 132. One end of the first capacitor 131 is connected to the power supply component 110, and the other end of the first capacitor 131 is connected to the ground by the first switch 121. The enable end of the first switch 121 is connected to the processor 123. The second capacitor 141 is connected in parallel to the second coil 142. One end of the second capacitor 141 is connected to the power supply component 110, and the other end of the second capacitor 141 is connected to the ground by the second switch 122. The enable end of the second switch 122 is connected to the processor.

[0033] Specifically, in this embodiment, the first coil 132 and the second coil 142 are wound in the same direction. That is, the first coil 132 and the second coil 142 are wound around the tubular heating element in the same manner. The tubular heating element has an accommodating space into which the vaporization substrate is inserted. During working, the processor 123 controls the first switch 121 to switch on / off. When the current output by the power supply component 110 passes through the first coil 132 and the first capacitor 131, the first coil 132 starts to work. In addition, the processor 123 controls the second switch 122 to switch on / off. When the current output by the power supply component 110 passes through the second coil 142 and the second capacitor 141, the second electromagnetic heating circuit 140 also starts to work. The processor 123 controls, by controlling the first switch 121 and the second switch 122 to switch on at different times, different energy to flow from the power supply component 110 to the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140, to control the working powers of the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140.

[0034] When a large current passes through the first coil 132 used as a main heater, induced electromotive forces having opposite directions are induced at two ends of the second coil 142. In this case, the processor 123 controls the current flowing through the second coil 142 and the current flowing through the first coil 132 to have the same direction, and controls the current flowing through the second coil 142 to be smaller than the current flowing through the first coil 132.

[0035] Therefore, the second coil 142 is driven to heat the second part of the heating element at a lower power for temperature preservation.

[0036] When a large current passes through the second coil 142 used as a main heater, induced electromotive forces having opposite directions are induced at two ends of the first coil 132. In this case, the control circuit of the first coil 132 controls the current flowing through the first coil 132 and the current flowing through the second coil 142 to have the same direction, and controls the current flowing through the first coil 132 to be smaller than the current flowing through the second coil 142, thereby driving the first coil 132 to heat the first part of the heating element at a smaller power for temperature preservation.

[0037] For example, as shown in FIG. 4, FIG. 4 is a schematic diagram of a voltage at a point A in a first electromagnetic heating circuit and a voltage at a point B in a second electromagnetic heating circuit according to an embodiment of this application. Specifically, within a time period of T1 to T2, the heating power of the first electromagnetic heating circuit 130 is the first power. The voltage at the end (equivalent to the point A shown in the figure) of the first electromagnetic heating circuit 130 connected to the first switch 121 starts to rise (that is, the voltage across the capacitor rises) and reaches the maximum voltage value corresponding to the first power, and then drops from the maximum voltage value to a preset valley value. This process is repeated. The internal magnetic field of the first electromagnetic heating circuit 130 continuously changes, so that the changing magnetic field generates a changing eddy current, for heating the vaporization substrate. The temperature in the corresponding first accommodating space reaches the first target temperature. It should be noted that the first target temperature may be a fixed value or may not be a fixed value provided that vaporization of the vaporization substrate can be ensured. The heating power of the second electromagnetic heating circuit 140 is the second power. The voltage at the point B in the second electromagnetic heating circuit 140 also starts to rise and reaches the maximum voltage value corresponding to the second power, and then drops. This process is repeated. The internal magnetic field of the second electromagnetic heating circuit 140 continuously changes, so that the changing magnetic field generates a changing eddy current, for heating the vaporization substrate. The temperature in the corresponding second accommodating space is maintained at the second target temperature. The second target temperature is a current temperature of the vaporization substrate or falls within a preset range of the current temperature.

[0038] Within a time period of T2 to T3, the heating power of the second electromagnetic heating circuit 140 is the first power. The voltage at the point B in the second electromagnetic heating circuit 140 continuously rises and drops. This process is repeated. The internal magnetic field continuously changes, so that the changing magnetic field generates a changing eddy current, for heating the vaporization substrate. The temperature in the corresponding second accommodating space reaches the first target temperature. Similarly, within the time period of T2 to T3, the heating power of the first electromagnetic heating circuit 130 is the second power, and the voltage at the point A continuously rises and drops, and changes repeatedly. This process is similar to the process described above. It should be noted that, the vaporization substrate corresponding to the first accommodating space and the second accommodating space correspond to respective temperature curves thereof, and when heating is performed at the first power, the temperatures of the first accommodating space and the second accommodating space are controlled to reach first temperatures in the corresponding temperature curves. Within the time period of T2 to T3, the heating power of the first electromagnetic heating circuit 130 is the second power. The voltage at the end (equivalent to the point A shown in FIG. 3) of the first electromagnetic heating circuit 130 connected to the second switch starts to drop from the maximum voltage value corresponding to the first power and then, rises to the maximum voltage value corresponding to the second power. This process is repeated. The internal magnetic field of the first electromagnetic heating circuit 130 continuously changes, so that the changing magnetic field generates a changing eddy current, for heating the vaporization substrate. The temperature in the corresponding first accommodating space is maintained at the second target temperature. It should also be noted that, the second target temperature is current temperatures in the temperature curves respectively corresponding to the vaporization substrate corresponding to the first accommodating space and the second accommodating space.

[0039] In another exemplary embodiment, as shown in FIG. 5, the first electromagnetic heating circuit 130 includes a first capacitor 131 and a first coil 132, and the second electromagnetic heating circuit 140 includes a second capacitor 141 and a second coil 142. The first capacitor 131 is connected in parallel to the first coil 132. One end of the first capacitor 131 is connected to the power supply component 110, and the other end of the first capacitor 131 is connected to the ground by the first switch 121. The enable end of the first switch 121 is connected to the processor 123. The second capacitor 141 is connected in parallel to the second coil 142. One end of the second capacitor 141 is connected to the power supply component 110, and the other end of the second capacitor 141 is connected to the ground by the second switch 122. The enable end of the second switch 122 is connected to the processor.

[0040] Specifically, in this embodiment, the first coil 132 and the second coil 142 are wound in opposite directions. That is, the first coil 132 and the second coil 142 are wound around the tubular heating element oppositely. The tubular heating element has an accommodating space into which the vaporization substrate is inserted. During working, the processor 123 controls the first switch 121 to switch on / off. When the current output by the power supply component 110 passes through the first coil 132 and the first capacitor 131, the first coil 132 starts to work. In addition, the processor 123 controls the second switch 122 to switch on / off. When the current output by the power supply component 110 passes through the second coil 142 and the second capacitor 141, the second electromagnetic heating circuit 140 also starts to work. The processor 123 controls, by controlling the first switch 121 and the second switch 122 to switch on at different times, different energy provided by the power supply component 110 to the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140, to control the working powers of the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140.

[0041] When a large current passes through the first coil 132 used as a main heater, induced electromotive forces having opposite directions are induced at two ends of the second coil 142. In this case, the processor 123 controls the current flowing through the second coil 142 and the current flowing through the first coil 132 to have opposite directions, and controls the current flowing through the second coil 142 to be smaller than the current flowing through the first coil 132, to drive the second coil 142 to heat the second part of the heating element at a smaller power for temperature preservation.

[0042] When a large current passes through the second coil 142 used as a main heater, induced electromotive forces having opposite directions are induced at two ends of the first coil 132. In this case, the control circuit of the first coil 132 controls the current flowing through the first coil 132 and the current flowing through the second coil 142 to have opposite directions, and controls the current flowing through the first coil 132 to be smaller than the current flowing through the second coil 142, thereby driving the first coil 132 to heat the first part of the heating element at a smaller power for temperature preservation.

[0043] Based on the same inventive idea, the embodiments of this application further provide a control method applied to the foregoing aerosol generation device. The solution to the problem provided by the method is similar to the implementation described in the foregoing aerosol generation device. Therefore, for specific limitations in one or more embodiments of the control method for an aerosol generation device provided below, reference may be made to the limitations on the aerosol generation device above. Details are not described herein again.

[0044] In an embodiment, as shown in FIG. 6, this application provides a control method for an aerosol generation device. Based on the foregoing embodiments, the method includes: Step S610: Control amounts of energy provided by a power supply component to a first electromagnetic heating circuit and a second electromagnetic heating circuit, to enable the second electromagnetic heating circuit to work at a second power when the first electromagnetic heating circuit works at a first power or enable the first electromagnetic heating circuit to work at a second power when the second electromagnetic heating circuit works at a first power, where the first power and the second power are not equal.

[0045] Specifically, this application can be applied to the control component described in any one of the foregoing embodiments. The control component 120 can control amounts of energy provided by the power supply component 110 to the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140, to enable the second electromagnetic heating circuit 140 to work at a second power when the first electromagnetic heating circuit 130 works at a first power or enable the first electromagnetic heating circuit 130 to work at a second power when the second electromagnetic heating circuit 140 works at a first power. It should be noted that the control component 120 can also independently control the first electromagnetic heating circuit 130 or the second electromagnetic heating circuit 140 to work.

[0046] It may be understood that, to enable the aerosol generation device to work normally, that is, to vaporize the vaporization substrate normally, a working power of one of the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140 is greater than or equal to the minimum vaporization power of the vaporization substrate, that is, one of the first power and the second power is greater than or equal to the minimum vaporization power of the vaporization substrate. The minimum vaporization power refers to a working power of a heating circuit corresponding to the minimum temperature at which the vaporization substrate can be normally vaporized. It should be noted that for different vaporization substrates, minimum vaporization powers corresponding to the vaporization substrates are also different. The first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140 both include a heating element and a coil. The heating element may sense a changing electromagnetic field and is made of a material that generates an induced eddy current. A temperature sensor capable of measuring the temperature is arranged on the surface of the heating element, to measure the temperature at a position corresponding to the heating element. The heating element is arranged in the changing electromagnetic field generated by the coil, and is partitioned into at least two main heating regions by a position at which the coil is arranged. The two main heating regions can be individually controlled by the coils to perform heating.

[0047] In a manner of performing heating by using two sections simultaneously, the two electromagnetic heating circuits can be controlled at proper temperatures respectively, thereby improving consistency between puffing effects of front and back sections. In this embodiment, the first power is greater than or equal to the minimum power for normal vaporization of the vaporization substrate in the aerosol generation device, and the second power is less than the minimum power and is greater than 0. Alternatively, the second power is greater than or equal to the minimum power for normal vaporization of the vaporization substrate in the aerosol generation device, and the first power is less than the minimum power and is greater than 0. That is, one of the first power and the second power is greater than or equal to the minimum vaporization power of the vaporization substrate, and the other is less than the minimum vaporization power of the vaporization substrate. Working is performed at a smaller power.

[0048] In the foregoing control method for an aerosol generation device, two electromagnetic heating circuits are separately controlled to work at the same time. One circuit works at the first power, and the other circuit works at the second power. That is, when one region of the vaporization substrate is heated at a high power, the other region maintains a current temperature state at a low power, so that the temperature of the vaporization substrate can be controlled within a preset temperature range more precisely, to achieve a target puffing effect. In addition, because the second power can maintain the current temperature state of the vaporization substrate, fluctuations of the temperature of the vaporization substrate in the entire heating process are small, so that the target temperature can be reached at a lower first power, which is conducive to precise temperature control, and reduces the power loss, thereby reducing the total power consumption of the system.

[0049] The first power is greater than or equal to the minimum power for normal vaporization of the vaporization substrate in the aerosol generation device, and the second power is less than the minimum power and is greater than 0. In this case, a received work instruction is to heat the vaporization substrate at a position at which the first electromagnetic heating circuit is located. Alternatively, the second power is greater than or equal to the minimum power for normal vaporization of the vaporization substrate in the aerosol generation device, and the first power is less than the minimum power and is greater than 0. In this case, a received work instruction is to heat the vaporization substrate at a position at which the second electromagnetic heating circuit is located.

[0050] Specifically, when being applied to the aerosol generation device shown in FIG. 2, the processor 123 can control the first switch 121 and the second switch 122 to switch on or off, to achieve, within a unit cycle, the duration in which the power supply component 110 is connected to the first electromagnetic heating circuit 130 by the first switch 121 and the duration in which the power supply component 110 is connected to the second electromagnetic heating circuit 140 by the second switch 122, to control, within the unit cycle, the energy received by the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140, that is, control the working powers of the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140.

[0051] When being applied to the aerosol generation device shown in FIG. 3 or FIG. 5, the processor 123 controls the first switch 121 to switch on / off, so that the current output by the power supply component passes through the first coil 132 and the first capacitor 131, and the first electromagnetic heating circuit 130 starts to work. In addition, the processor 123 controls the second switch 122 to switch on, so that the current output by the power supply component 110 passes through the second coil 142 and the second capacitor 141, and the second electromagnetic heating circuit 140 also starts to work. The processor 123 controls, by controlling the first switch 121 and the second switch 122 to switch on at different times, different energy provided by the power supply component 110 to the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140, to control the working powers of the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140.

Unless otherwise clearly specified in this specification, the steps are performed without any strict sequence limit, and may be performed in other sequences.
