Description

Technical Field

[0001] This application relates to the field of atomizing equipment, and in particular to an aerosol generating device and its control method and control device. Background Technology

[0002] The working principle of the aerosol generating device is mainly to heat the atomizing matrix by means of atomization without combustion, so that the components of the tobacco segment of the atomizing matrix volatilize and are inhaled by the user, thereby achieving the smoking experience.

[0003] Commonly used heating technologies include electromagnetic heating. Electromagnetic heating uses a tubular metal heating element to contain the atomized substrate, generating heat upon sensing an alternating magnetic field from a coil. This heat is then conducted to heat the atomized substrate. Furthermore, depending on the length of the atomized substrate, the tobacco segment can be heated in a single or dual-segment manner. For example, patent application CN109843097A discloses a dual-segment electromagnetic heating method. The induction heating device includes two induction coils, each controlled separately. When one induction coil is operating normally, the other is deactivated. This method is prone to interference between the two induction coils, leading to significant temperature fluctuations and hindering temperature control. Summary of the Invention

[0004] Therefore, it is necessary to provide an aerosol generating device and its control method and device that can reduce temperature fluctuations to address the above-mentioned technical problems.

[0005] In a first aspect, this application provides an aerosol generating apparatus. The aerosol generating apparatus includes:

[0006] The system includes a power module, a control module, a first electromagnetic heating circuit, and a second electromagnetic heating circuit. The first electromagnetic heating circuit forms a first accommodating space, and the second electromagnetic heating circuit forms a second accommodating interval. The first electromagnetic heating circuit is used to heat the atomizing matrix in the first accommodating space, and the second electromagnetic heating circuit is used to heat the atomizing matrix in the second accommodating space.

[0007] The power module is used to provide energy to the first electromagnetic heating circuit and the second electromagnetic heating circuit.

[0008] The control module is used to control the amount of energy provided by the power supply module to the first electromagnetic heating circuit and the second electromagnetic heating circuit, so that when the first electromagnetic heating circuit operates at a first power, the second electromagnetic heating circuit operates at a second power, or when the second electromagnetic heating circuit operates at a first power, the first electromagnetic heating circuit operates at a second power, and the first power and the second power are not equal.

[0009] In one embodiment, the first power is greater than or equal to the minimum power for normal atomization of the atomizing matrix in the aerosol generating device, and the second power is less than the minimum power and greater than 0.

[0010] In one embodiment, when the first electromagnetic heating circuit or the second electromagnetic circuit operates at a first power, the temperature of the first accommodating space or the second accommodating space reaches a first target temperature; when the first electromagnetic heating circuit or the second electromagnetic circuit operates at a second power, the temperature of the first accommodating space or the second accommodating space is maintained at a second target temperature or a preset temperature range, wherein the second target temperature belongs to the preset temperature range.

[0011] In one embodiment, the control module includes:

[0012] First switch, second switch, and processor;

[0013] The first terminal of the first switch is connected to the power module, the second terminal is connected to the first electromagnetic heating circuit, and the enable terminal is connected to the processor.

[0014] The first end of the second switch is connected to the power module, the second end is connected to the second electromagnetic heating circuit, and the enable end is connected to the processor.

[0015] In one embodiment, the processor is configured to control the on-time of the first switch and the second switch such that when the first electromagnetic heating circuit operates at a first power, the second electromagnetic heating circuit operates at a second power, or when the second electromagnetic heating circuit operates at a first power, the first electromagnetic heating circuit operates at a second power, wherein the on-time of the first switch or the second switch corresponding to the first power is greater than the on-time of the second switch or the first switch corresponding to the second power.

[0016] In one embodiment, the first electromagnetic heating circuit includes a first capacitor and a first coil, and the second electromagnetic heating circuit includes a second capacitor and a second coil.

[0017] The first capacitor is connected in parallel with the first coil. One end of the first capacitor is connected to the power module, and the other end is grounded through the first switch. The enable terminal of the first switch is connected to the processor.

[0018] The second capacitor is connected in parallel with the second coil. One end of the second capacitor is connected to the power module, and the other end is grounded through the second switch. The enable terminal of the second switch is connected to the processor.

[0019] In one embodiment, the coils of the first electromagnetic heating circuit and the second electromagnetic heating circuit have the same winding direction.

[0020] In one embodiment, the coils of the first electromagnetic heating circuit and the coils of the second electromagnetic heating circuit are wound in opposite directions.

[0021] Secondly, this application also provides a temperature control method for an aerosol generating apparatus, the method comprising:

[0022] The power supply module provides energy to the first electromagnetic heating circuit and the second electromagnetic heating circuit such that when the first electromagnetic heating circuit operates at a first power, the second electromagnetic heating circuit operates at a second power, or when the second electromagnetic heating circuit operates at a first power, the first electromagnetic heating circuit operates at a second power, and the first power and the second power are not equal.

[0023] Thirdly, this application also provides a temperature control device for an aerosol generating apparatus, the device comprising:

[0024] The control module is used to control the amount of energy supplied by the power supply module to the first electromagnetic heating circuit and the second electromagnetic heating circuit, so that when the first electromagnetic heating circuit operates at a first power, the second electromagnetic heating circuit operates at a second power, or when the second electromagnetic heating circuit operates at a first power, the first electromagnetic heating circuit operates at a second power, wherein the first power and the second power are not equal.

[0025] The aforementioned aerosol generating device and its control method and control device include: a power supply module, a control module, a first electromagnetic heating circuit and a second electromagnetic heating circuit. The first electromagnetic heating circuit forms a first accommodating space, and the second electromagnetic heating circuit forms a second accommodating interval. The first electromagnetic heating circuit is used to heat the atomizing matrix in the first accommodating space, and the second electromagnetic heating circuit is used to heat the atomizing matrix in the second accommodating space. The power supply module is used to provide energy to the first and second electromagnetic heating circuits. The control module is used to control the amount of energy provided by the power supply module to the first and second electromagnetic heating circuits, such that when the first electromagnetic heating circuit operates at a first power, the second electromagnetic heating circuit operates at a second power, or when the second electromagnetic heating circuit operates at a first power, the first electromagnetic heating circuit operates at a second power, wherein the first power and the second power are not equal. In this way, to achieve the target taste, this application controls two electromagnetic heating circuits to operate simultaneously. One circuit operates at a first power, while the other operates at a second power. That is, while one area of ​​the atomized matrix is ​​heated at a high power, the other area maintains its current temperature at a low power. This allows the temperature of the atomized matrix to be more accurately within the preset temperature range to achieve the target taste. On the other hand, since the second power can maintain the current temperature of the atomized matrix, the temperature fluctuation of the atomized matrix is ​​smaller throughout the heating process, allowing the target temperature to be reached with a relatively low first power. This is beneficial for precise temperature control, reduces power loss, and thus reduces the overall power consumption of the system. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0034] In one embodiment, an aerosol generating apparatus is provided, such as... Figure 1 As shown, the aerosol generating device includes:

[0035] The system includes a power module 110, a control module 120, a first electromagnetic heating circuit 130, and a second electromagnetic heating circuit 140. In this embodiment, the electromagnetic heating circuits (i.e., the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140) include, but are not limited to, LC series resonant circuits, LC parallel resonant circuits, single-tube parallel resonant circuits, half-bridge series resonant circuits, full-bridge series resonant circuits, and Class E power amplifier resonant circuits. The first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140 each form an accommodating space (not shown in the figure). Specifically, the first electromagnetic heating circuit 130 forms a first accommodating space, and the second electromagnetic heating circuit 140 forms a second accommodating space. Both accommodating spaces are used to place the atomizing substrate. The first electromagnetic heating circuit 130 is used to heat the atomizing substrate in the first accommodating space, and the second electromagnetic heating circuit 140 is used to heat the atomizing substrate in the second accommodating space. It should be noted that the atomizing substrate in the first accommodating space and the second accommodating space is the same atomizing substrate; that is, a portion of the atomizing substrate is located in the first accommodating space, and another portion is located in the second accommodating space. 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 supply module 110.

[0036] Power module 110 provides energy to the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140. Power module 110 also provides energy to control module 120, enabling control module 120, the first electromagnetic heating circuit 130, and the second electromagnetic heating circuit 140 to operate normally. The first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140 heat the atomizing matrix passing through their respective accommodating spaces according to the received energy, forming an aerosol for the user to inhale.

[0037] The control module 120 is used 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 at a first power, the second electromagnetic heating circuit 140 operates at a second power, or when the second electromagnetic heating circuit 140 operates at a first power, the first electromagnetic heating circuit 130 operates at a second power, and the first power and the second power are not equal.

[0038] Specifically, during the control process, the control module 120 can control the amount of energy supplied by the power supply module 110 to the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140, thereby causing the first electromagnetic heating circuit 130 to operate at a first power and the second electromagnetic heating circuit 140 to operate at a second power, or vice versa. It should be noted that the control module 120 can also control either the first electromagnetic heating circuit 130 or the second electromagnetic heating circuit 140 to operate independently.

[0039] It is understandable that, in order for the aerosol generating device to function properly, i.e., to atomize the atomized matrix correctly, the operating power of at least one of the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140 must be greater than or equal to the minimum atomization power of the atomized matrix. That is, at least one of the first power and the second power must be greater than or equal to the minimum atomization power of the atomized matrix (the minimum atomization power refers to the operating power of the heating circuit corresponding to the minimum temperature at which the atomized matrix can be normally atomized). It should be noted that different atomized matrices will have different minimum atomization powers. Both the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140 include a heating element and a coil. The heating element is made of a material that can sense changing electromagnetic fields and generate induced eddy currents. A temperature sensor is arranged on the surface of the heating element to measure the temperature at the corresponding location. The heating element is positioned within the changing electromagnetic field generated by the coil and is divided into at least two main heating areas by the coil's location. These two heating areas can heat different parts of the atomized matrix respectively.

[0040] Furthermore, to avoid excessive power consumption of the aerosol generating device due to both heating circuits operating at high power simultaneously (i.e., both heating circuits operating at a power greater than the minimum atomization power of the atomizing matrix), a two-stage heating method is employed. This allows for control of the two electromagnetic heating circuits at appropriate temperatures, thereby improving the consistency of the taste before and after heating. In this embodiment, the first power is greater than or equal to the minimum power for normal atomization of the atomizing matrix within the aerosol generating device, and the second power operates at a power less than the minimum power, but greater than 0; or the second power is greater than or equal to the minimum power for normal atomization of the atomizing matrix within the aerosol generating device, and the first power operates at a power less than the minimum power, but greater than 0. That is, at least one of the first power and the second power is greater than or equal to the minimum atomization power of the atomizing matrix, while the other is less than the minimum atomization power of the atomizing matrix, operating at a lower power.

[0041] It is understandable 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.

[0042] The aforementioned aerosol generating device includes: a power supply module, a control module, a first electromagnetic heating circuit, and a second electromagnetic heating circuit. The first electromagnetic heating circuit forms a first accommodating space, and the second electromagnetic heating circuit forms a second accommodating region. The first electromagnetic heating circuit is used to heat the atomizing matrix within the first accommodating space, and the second electromagnetic heating circuit is used to heat the atomizing matrix within the second accommodating space. The power supply module is used to provide energy to the first and second electromagnetic heating circuits. The control module is used to control the amount of energy provided by the power supply module to the first and second electromagnetic heating circuits, such that when the first electromagnetic heating circuit operates at a first power, the second electromagnetic heating circuit operates at a second power, or when the second electromagnetic heating circuit operates at a first power, the first electromagnetic heating circuit operates at a second power, wherein the first power and the second power are not equal. In this way, to achieve the target taste, this application controls two electromagnetic heating circuits to operate simultaneously. One circuit operates at a first power, while the other operates at a second power. That is, while one area of ​​the atomized matrix is ​​heated at a high power, the other area maintains its current temperature at a low power. This allows the temperature of the atomized matrix to be more accurately kept within the preset temperature range to achieve the target taste. On the other hand, since the second power can maintain the current temperature of the atomized matrix, the temperature fluctuation of the atomized matrix is ​​smaller throughout the heating process, allowing the target temperature to be reached with a relatively low first power. This facilitates precise temperature control, reduces power loss, and thus lowers the overall power consumption of the system.

[0043] As one example, see Figure 2 The control module 120 includes:

[0044] 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 module 110, the second end is connected to the first electromagnetic heating circuit 130, and the enable end is connected to the processor 123; the first end of the second switch 122 is connected to the power module 110, the second end is connected to the second electromagnetic heating circuit 140, and the enable end is connected to the processor 123.

[0045] In this embodiment, the first switch 121 and the second switch 122 can be MOSFETs, but in specific implementations, they can be other types of switches. The control module 120 is connected to the enable terminals of the first switch 121 and the second switch 122. The control module 120 can control the on / off state of the first switch 121 and the second switch 122, thereby controlling the duration for which the power module 110 is connected to the first electromagnetic heating circuit 130 via the first switch 121 and the duration for which the power module 110 is connected to the second electromagnetic heating circuit 140 via the second switch 122 within a unit cycle. This allows control over the energy received by the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140 within a unit cycle, thus controlling the energy received by the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140. The operating power of circuit 130 and the second electromagnetic heating circuit 140 is specifically controlled by adjusting the on and off times of the first switch 121 to control the first electromagnetic heating circuit 130 to operate at a first power, and simultaneously adjusting the on and off times of the second switch 122 to control the second electromagnetic heating circuit 140 to operate at a second power; or, adjusting the on and off times of the second switch 122 to control the second electromagnetic heating circuit 140 to operate at the first power, and simultaneously adjusting the on and off times of the first switch 121 to control the first electromagnetic heating circuit 130 to operate at the second power. When the first electromagnetic heating circuit 130 operates at the first power, the on-time of the corresponding first switch 121 is greater than the on-time of the corresponding second switch 122, or when the second electromagnetic heating circuit 140 operates at the first power, the on-time of the corresponding second switch 122 is greater than the on-time of the corresponding first switch 121, thus ensuring that the first power is greater than the second power.

[0046] As another embodiment, see Figure 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 with the first coil 132. One end of the first capacitor 131 is connected to the power module 110, and the other end is grounded through the first switch 121. The enable terminal of the first switch 121 is connected to the processor 123. The second capacitor 141 is connected in parallel with the second coil 142. One end of the second capacitor 141 is connected to the power module 110, and the other end is grounded through the second switch 122. The enable terminal of the second switch 122 is connected to the processor.

[0047] 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 on the tubular heating body in the same way, and the tubular heating body has a accommodating space for inserting the atomizing matrix. During operation, the processor 123 controls the first switch 121 to turn on / off, so 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 working. At the same time, the processor 123 controls the second switch 122 to turn on / off, so 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 working. By controlling the different on times of the first switch 121 and the second switch 122, the processor 123 controls the energy flowing from the power module 110 to the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140, thereby controlling the working power of the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140.

[0048] When a large current flows through the first coil 132 as the main heater, an induced electromotive force in the opposite direction is generated across the second coil 142. At this time, the processor 123 controls the current flowing through the second coil 142 to be in the same direction as that flowing through the first coil 132, and controls the magnitude of the current flowing through the second coil 142 to be smaller than that flowing through the first coil 132. This drives the second coil 142 to heat the second part of the heating element with lower power.

[0049] When a large current flows through the second coil 142 as the main heater, an induced electromotive force in the opposite direction is generated across the first coil 132. At this time, the control circuit of the first coil 132 controls the current flowing through it to be in the same direction as that flowing through the second coil 142, and controls the magnitude of the current flowing through the first coil 132 to be smaller than that flowing through the second coil 142. This drives the first coil 132 to heat the first part of the heating element with relatively low power.

[0050] For example, see Figure 4 , Figure 4The diagram illustrates the voltage at point A of the first electromagnetic heating circuit and point B of the second electromagnetic heating circuit during operation. Specifically, during the time period T1 to T2, the heating power of the first electromagnetic heating circuit 130 is at its first power. The voltage at the end of the first electromagnetic heating circuit 130 connected to the first switch 121 (corresponding to point A in the diagram) begins to rise (i.e., the voltage across the capacitor rises) and reaches the maximum voltage value corresponding to the first power. Then, the voltage drops from the maximum voltage value to a preset valley value, and this process repeats. The internal magnetic field of the first electromagnetic heating circuit 130 continuously changes, thereby generating changing eddy currents, which heat the atomized substrate. The corresponding first accommodating space... The temperature inside the space reaches the first target temperature. It should be noted that the first target temperature can be a fixed value or not, as long as it can ensure the atomization of the atomization substrate. The heating power of the second electromagnetic heating circuit 140 is the second power. The voltage at point B in the second electromagnetic heating circuit 140 also begins to rise and reaches the maximum voltage corresponding to the second power, and then falls. This process repeats, and the magnetic field inside the second electromagnetic heating circuit 140 changes continuously. The changing magnetic field generates changing eddy currents, thereby heating the atomization substrate and maintaining the temperature of the corresponding second accommodating space at the second target temperature. The second target temperature is the current temperature of the atomization substrate, or within a preset range of the current temperature.

[0051] During the time period T2 to T3, the heating power of the second electromagnetic heating circuit 140 is the first power. The voltage at point B in the second electromagnetic heating circuit 140 continuously rises and falls, repeating this cycle. This causes continuous changes in the internal magnetic field, generating changing eddy currents that heat the atomized substrate. The temperature within the corresponding second accommodating space reaches the first target temperature. Similarly, during the time period T2 to T3, the heating power of the first electromagnetic heating circuit 130 is the second power, and the voltage at point A continuously rises and falls, repeating the cycle. It should be noted that the atomized substrates in the first and second accommodating intervals correspond to their respective temperature curves. When heated with the first power, the temperature is controlled to reach the first temperature of the corresponding temperature curve. During the time period T2 to T3, the heating power of the first electromagnetic heating circuit 130 is the second power. One end of the first electromagnetic heating circuit 130 connected to the second switch (equivalent to...) Figure 3 The voltage at point A decreases 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 repeats, causing the magnetic field inside the first electromagnetic heating circuit 130 to change continuously. This changing magnetic field generates changing eddy currents, which in turn heat the atomizing matrix. The temperature of the corresponding first accommodating space is maintained at the second target temperature. It should also be noted that the second target temperature is the current temperature of the temperature curves corresponding to the atomizing matrix in the first and second accommodating intervals.

[0052] As another embodiment, see Figure 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 with the first coil 132. One end of the first capacitor 131 is connected to the power module 110, and the other end is grounded through the first switch 121. The enable terminal of the first switch 121 is connected to the processor 123. The second capacitor 141 is connected in parallel with the second coil 142. One end of the second capacitor 141 is connected to the power module 110, and the other end is grounded through the second switch 122. The enable terminal of the second switch 122 is connected to the processor.

[0053] Specifically, in this embodiment, the winding directions of the first coil 132 and the second coil 142 are opposite, that is, the first coil 132 and the second coil 142 are wound on the tubular heating body in opposite ways, and the tubular heating body has a accommodating space for inserting the atomizing matrix. During operation, the processor 123 controls the first switch 121 to turn on / off, so 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 working. At the same time, the processor 123 controls the second switch 122 to turn on / off, so 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 working. By controlling the different on times of the first switch 121 and the second switch 122, the processor 123 controls the energy flowing from the power module 110 to the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140, thereby controlling the operating power of the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140.

[0054] When a large current flows through the first coil 132 as the main heater, an induced electromotive force in the opposite direction is generated across the second coil 142. At this time, the processor 123 controls the current flowing through the second coil 142 to be in the opposite direction to that flowing through the first coil 132, and controls the magnitude of the current flowing through the second coil 142 to be smaller than that flowing through the first coil 132. This drives the second coil 142 to heat the second part of the heating element with lower power.

[0055] When a large current flows through the second coil 142 as the main heater, an induced electromotive force in the opposite direction is generated across the first coil 132. At this time, the control circuit of the first coil 132 controls the current flowing through it to be in the opposite direction to that flowing through the second coil 142, and also controls the magnitude of the current flowing through the first coil 132 to be smaller than that flowing through the second coil 142. This drives the first coil 132 to heat the first part of the heating element with relatively low power.

[0056] Based on the same inventive concept, this application also provides a control method for implementing the aerosol generating device described above. The solution provided by this method is similar to the solution described in the aerosol generating device above. Therefore, the specific limitations in the control method embodiments of one or more aerosol generating devices provided below can be found in the limitations of the aerosol generating device described above, and will not be repeated here.

[0057] In one embodiment, such as Figure 6 As shown, this application provides a control method for an aerosol generating device. Based on the above embodiments, the method includes:

[0058] Step 610: Control the amount of energy supplied by the power supply module to the first electromagnetic heating circuit and the second electromagnetic heating circuit, so that when the first electromagnetic heating circuit operates at a first power, the second electromagnetic heating circuit operates at a second power, or when the second electromagnetic heating circuit operates at a first power, the first electromagnetic heating circuit operates at a second power, and the first power and the second power are not equal.

[0059] Specifically, this application can be applied to the control module described in any of the above embodiments. 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, thereby causing the first electromagnetic heating circuit 130 to operate at a first power and the second electromagnetic heating circuit 140 to operate at a second power, or vice versa. It should be noted that the control module 120 can also control either the first electromagnetic heating circuit 130 or the second electromagnetic heating circuit 140 to operate independently.

[0060] It is understandable that, in order for the aerosol generating device to function properly, i.e., to atomize the atomized matrix correctly, the operating power of at least one of the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140 must be greater than or equal to the minimum atomization power of the atomized matrix. That is, at least one of the first power and the second power must be greater than or equal to the minimum atomization power of the atomized matrix (the minimum atomization power refers to the operating power of the heating circuit corresponding to the minimum temperature at which the atomized matrix can be normally atomized). It should be noted that different atomized matrices will have different minimum atomization powers. Both the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140 include a heating element and a coil. The heating element is made of a material that can sense changing electromagnetic fields and generate induced eddy currents. A temperature sensor is arranged on the surface of the heating element to measure the temperature at the corresponding location. The heating element is positioned within the changing electromagnetic field generated by the coil and is divided into at least two main heating areas by the coil's placement. Each heating area can be individually controlled by the coil for heating.

[0061] Simultaneous use of a two-stage heating method allows for precise temperature control of the two electromagnetic heating circuits, improving the consistency of the taste throughout. In this embodiment, the first power is greater than or equal to the minimum power required for normal atomization of the atomizing matrix within the aerosol generating device, while the second power operates below the minimum power and is greater than 0; or the second power is greater than or equal to the minimum power required for normal atomization of the aerosol generating device, while the first power operates below the minimum power and is greater than 0. That is, at least one of the first and second powers is greater than or equal to the minimum atomization power of the atomizing matrix, while the other is less than the minimum atomization power of the atomizing matrix, operating at a lower power.

[0062] The control method of the above-mentioned aerosol generating device controls two electromagnetic heating circuits to operate simultaneously. One circuit operates at a first power, while the other operates at a second power. That is, while one area of ​​the atomized matrix is ​​heated at a high power, the other area maintains its current temperature at a low power. This allows the temperature of the atomized matrix to be more accurately kept within the preset temperature range to achieve the target taste. On the other hand, since the second power can maintain the current temperature of the atomized matrix, the temperature fluctuation of the atomized matrix is ​​smaller throughout the heating process, allowing the target temperature to be reached with a relatively low first power. This is beneficial for precise temperature control, reduces power loss, and thus reduces the overall power consumption of the system.

[0063] Wherein, if the first power is greater than or equal to the minimum power for normal atomization of the atomizing matrix in the aerosol generating device, and the second power is less than the minimum power but greater than 0, then the received working instruction is to heat the atomizing matrix at the location of the first electromagnetic heating circuit; or, if the second power is greater than or equal to the minimum power for normal atomization of the atomizing matrix in the aerosol generating device, and the first power is less than the minimum power but greater than 0, then the received working instruction is to heat the atomizing matrix at the location of the second electromagnetic heating circuit.

[0064] Specifically, in applications such as Figure 2 In the aerosol generating device shown, the processor 123 controls the first switch 121 and the second switch 122 to turn on or off, thereby controlling the duration for which the power module 110 is connected to the first electromagnetic heating circuit 130 through the first switch 121 and the duration for which the power module 110 is connected to the second electromagnetic heating circuit 140 through the second switch 122 within a unit cycle. This controls the energy received by the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140 within a unit cycle, thus controlling the operating power of the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140.

[0065] In applications such as Figure 3 or Figure 5 When the aerosol generating device is used, the processor 123 controls the first switch 121 to turn on, so the current output from the power module passes through the first coil 132 and the first capacitor 131, and the first electromagnetic heating circuit 130 starts working. Simultaneously, the processor 123 controls the second switch 122 to turn on, so the current output from the power module 110 passes through the second coil 142 and the second capacitor 141, and the second electromagnetic heating circuit 140 also starts working. By controlling the different on times of the first switch 121 and the second switch 122, the processor 123 controls the energy flowing from the power module 110 to the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140, thereby controlling the operating power of the first electromagnetic heating circuit 130 and the second electromagnetic heating circuit 140.
