As an example, the control module 120 is connected to the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140, respectively, and the control module 120 is also connected to the power module 110.
The power module 110 is configured to supply power to the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140, and the same power module 110 also supplies power to the control module 120, so that the control module 120, the first electromagnetic heating circuit 130, and the second electromagnetic heating circuit 140 operate normally. The first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140 heat the atomized substrate passing through the accommodating space of the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140 according to the received energy, so as to form aerosol for the user to suck.
The control module 120 is configured to control the amount of energy provided by the power supply module 110 to the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140, so that when the first electromagnetic heating circuit 130 operates with a first power, the second electromagnetic heating circuit 140 operates with a second power, or when the second electromagnetic heating circuit 140 operates with a first power, the first electromagnetic heating circuit 130 operates with a second power, and the first power and the second power are unequal.
Specifically, during the control process, the control module 120 can control the amount of energy provided by the power supply module 110 to the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140, such that the first electromagnetic heating circuit 130 operates at a first power and the second electromagnetic heating circuit 140 operates at a second power, or the first electromagnetic heating circuit 130 operates at a second power when the second electromagnetic heating circuit 140 operates at the first power.

I.e. at least one of the first power and the second power is greater than or equal to the minimum atomizing power of the atomized substrate and the other is less than the minimum atomizing power of the atomized substrate, at a lesser power.
It is understood that the sum of the first power and the second power is less than or equal to the maximum output power of the power module 110.

In the time period from 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 falls, and thus the internal magnetic field is continuously changed, so that the changing magnetic field generates changing eddy current to heat the atomized substrate, the temperature in the corresponding second accommodating space reaches the first target temperature, and in the time period from T2 to T3, the heating power of the first electromagnetic heating circuit 130 is the second power, the voltage at the point a continuously rises and falls, and the process is repeatedly changed, similar to the above.

In operation, the processor 123 controls the on/off of the first switch 121, so that the current output by the power module 110 passes through the first coil 132 and the first capacitor 131, and the first coil 132 starts to operate. At the same time, the second switch 122 is controlled to be turned on/off, so that the current output by the power module 110 passes through the second coil 142 and the second capacitor 141, and the second electromagnetic heating circuit 140 also starts to work.

The surface of the heating body is provided with a temperature sensor capable of measuring temperature and used for measuring the temperature of the corresponding position of the heating body. The heating element is arranged in a varying electromagnetic field generated by the coil and is divided by the position of the coil arrangement into at least two main heating zones, which can be individually controlled to be heated by the coil.
Meanwhile, a two-section heating mode is adopted, so that the two sections of electromagnetic heating circuits can be controlled to be at proper temperatures respectively, and the consistency of front and rear tastes is improved. In the implementation, the first power is larger than or equal to the minimum power for normal atomization of the atomized matrix in the aerosol generating device, and the second power works smaller than the minimum power and larger than 0; or the second power is greater than or equal to the minimum power at which the nebulized matrix is normally nebulized in the aerosol-generating device, the first power being operated less than said minimum power and greater than 0. I.e. at least one of the first power and the second power is greater than or equal to the minimum atomizing power of the atomized substrate and the other is less than the minimum atomizing power of the atomized substrate, at a lesser power.
According to the control method of the aerosol generating device, two electromagnetic heating circuits are controlled to work simultaneously, one circuit works with first power, and the other circuit works with second power, namely when one area of the atomized substrate is heated with high power, the other area maintains the current temperature state with low power, so that the temperature of the atomized substrate is more accurate within a preset temperature range, and the target taste is achieved; on the other hand, as the second power can maintain the current temperature state of the atomized matrix, the temperature fluctuation of the atomized matrix in the whole heating process is small, so that the first power with relatively low temperature can reach the target temperature, the accurate control of the temperature is facilitated, the power loss is small, and the effect of reducing the total power consumption of the system is further achieved.
The first power is greater than or equal to the minimum power for normal atomization of the atomized matrix in the aerosol generating device, the second power is smaller than the minimum power and greater than 0, and at the moment, the received working instruction is to heat the atomized matrix at the position of the first electromagnetic heating circuit; or the second power is greater than or equal to the minimum power for normal atomization of the atomized matrix in the aerosol generating device, the first power works less than the minimum power and is greater than 0, and at the moment, the received working instruction is to heat the atomized matrix at the position of the second electromagnetic heating circuit.

When applied to the aerosol-generating device as shown in fig. 3 or 5, the processor 123 controls the first switch 121 to be turned on, and the current output by the power module passes through the first coil 132 and the first capacitor 131, and the first electromagnetic heating circuit 130 starts to operate. At the same time, the second switch 122 is controlled to be turned on, so that the current output by the power module 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 the power supplied from the power supply module 110 to the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140 by controlling the conduction time of the first switch 121 and the second switch 122 to be different, thereby controlling the operating power of the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140.
