[0047] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0050] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0051] like Figure 1 and Figure 2 As shown, a first aspect of an embodiment of the present invention proposes a heating device 100, which is configured to heat an adapted aerosol generating substrate 200. The aerosol generating substrate 200 and the heating device 100 are arranged in a plug-in structure. When the aerosol generating substrate 200 is inserted into the heating device 100 and reaches the heating position, the heating device 100 starts heating, and when the aerosol generating substrate 200 is pulled out of the heating position, the heating device 100 stops heating. An aerosol generating substrate 200 is provided with an atomizing medium, and the atomizing medium generates an aerosol when heated.
[0052] Among them, the aerosol generating matrix 200 is also provided with a magnetic medium 240, and the magnetic medium 240 is distributed in accordance with a preset distribution rule through a certain coding method. The magnetic medium 240 is not magnetized before the aerosol generating matrix 200 is heated and used. The magnetic medium 240 is non-magnetic or weakly magnetic. When the magnetic medium 240 is in direct or indirect contact with the magnetic detection circuit 30, no electrical signal is generated or a weak electrical signal is generated, and the characteristic information cannot be determined and identified.
[0053] To this end, in order to simplify the magnetization cost and production operation, optionally, the heating device 100 includes a heating mechanism 10 , a pre-magnetization unit 20 , a magnetic detection circuit 30 and a main control circuit 40 .
[0054] Among them, the heating mechanism 10 is provided with a accommodating cavity 12 for accommodating the aerosol generating matrix 200, and the accommodating cavity 12 has an opening 11 for inserting and removing the aerosol generating matrix 200. The heating mechanism 10 is also provided with a heating component 13 for heating the aerosol generating matrix 200. The shape of the accommodating cavity 12 is adapted to the aerosol generating matrix 200. For example, when the aerosol generating matrix 200 is a columnar structure, the accommodating cavity 12 is also set to a columnar structure, and the internal size of the accommodating cavity 12 is larger than the size of the aerosol generating matrix 200 and the size is close to that of the aerosol generating matrix 200, so as to perform a limiting effect when the aerosol generating matrix 200 is inserted and removed.
[0055] The accommodating cavity 12 is a hollow structure, and the accommodating cavity 12 can be generated by surrounding thin sheets of corresponding materials. For example, a metal thin sheet is surrounded by welding, clamping, etc. to form a accommodating cavity 12. An opening 11 is left at one end of the accommodating cavity 12 for plugging and unplugging the aerosol generating matrix 200.
[0056] Alternatively, the accommodating cavity 12 may also be generated by opening a hole on the corresponding substrate, for example, the accommodating cavity 12 may be generated on a substrate of silicon material or metal material by deposition, drilling, etc., and the hole opening is the opening 11 of the accommodating cavity 12 .
[0057] The heating component 13 is specifically arranged relative to the accommodating chamber 12 according to the structure of the aerosol generating substrate 200 and the installation position of the atomizing medium. It can be arranged at a corresponding position on the inner wall, bottom or outside of the accommodating chamber 12. The medium segment 210 of the aerosol generating substrate 200 is inserted from the opening 11 of the accommodating chamber 12 and directly reaches the corresponding heating position of the accommodating chamber 12. Corresponding to the structure of the aerosol generating substrate 200, optionally, the accommodating chamber 12 is a columnar structure, and the heating component 13 is located at the bottom of the accommodating chamber 12, or is arranged outside the accommodating chamber 12 and relative to the bottom of the accommodating chamber 12.
[0058] When the heating component 13 is disposed at the bottom of the accommodating cavity 12, when the aerosol generating substrate 200 reaches the heating position, the heating component 13 directly heats the aerosol generating substrate 200; and, when the heating component 13 is disposed outside the accommodating cavity 12 and relative to the bottom of the accommodating cavity 12, when the aerosol generating substrate 200 reaches the heating position, the heating component 13 indirectly heats the aerosol generating substrate 200 through the cavity of the accommodating cavity 12.
[0059] The pre-magnetization unit 20 can be arranged near the opening 11 of the accommodating cavity 12 or at other positions of the accommodating cavity 12. The pre-magnetization unit 20 magnetizes the magnetic medium 240 so that the magnetic medium 240 carries coded information. The pre-magnetization unit 20 has magnetism. By magnetizing the magnetic medium 240, that is, polarizing it, the magnetic medium 240 presents an N pole and / or an S pole. The magnetic medium 240 carries coded information. The polarized magnetic medium 240 converts a series of binary digital information into a magnetic signal of corresponding polarity according to a preset distribution rule. For example, the polarized magnetic medium 240 includes an N-pole magnetic medium segment and an S-pole magnetic medium segment. The N-pole magnetic medium segment and the S-pole magnetic medium segment are alternately distributed. At the same time, the width and alternation of the N-pole magnetic medium segment and the S-pole magnetic medium segment are set in accordance with the binary digital information. The N-pole magnetic medium segment outputs a magnetic signal corresponding to "1", and the S-pole magnetic medium segment outputs a magnetic signal corresponding to "0".
[0060] By attaching and recording the coded information on the magnetic medium 240 , the recording density is high and the coding methods are diverse. A variety of coded information can be recorded on a magnetic medium 240 with a smaller width, so that the heating device 100 can identify a variety of different aerosol generating matrices 200 .
[0061] The detection terminal of the magnetic detection circuit 30 is arranged on the accommodating cavity 12 or is spaced relative to the accommodating cavity 12. The distance between the magnetic detection circuit 30 and the opening 11 of the accommodating cavity 12 is greater than the distance between the pre-magnetization unit 20 and the opening 11 of the accommodating cavity 12. The magnetic detection circuit 30 is configured to obtain coded information when the aerosol generating matrix 200 is inserted and removed, and convert the output electrical signal.
[0062] The main control circuit 40 is connected to the magnetic detection circuit 30 and the heating component 13, and is configured to determine characteristic information of the aerosol generating matrix 200 according to the electrical signal, and trigger the heating component 13 to start or stop heating according to the characteristic information.
[0063] The magnetic detection circuit 30 is arranged at a position farther away from the opening 11 of the accommodating chamber 12 than the pre-magnetization unit 20. After magnetization, the magnetic medium 240 is accompanied by coding information. When the aerosol generating matrix 200 is inserted into the accommodating chamber 12, the magnetic medium 240 with the coding information passes through the magnetic detection circuit 30. The magnetic detection circuit 30 senses the magnetic signal of the magnetic medium 240 and outputs an electrical signal with the coding information. The main control circuit 40 records the coding information through the electrical signal and identifies the characteristic information of the aerosol generating matrix 200 corresponding to the coding information, and determines whether it is the aerosol generating matrix 200 matching the atomization device, and performs corresponding early warning operations and heating control.
[0064] Optionally, in order to implement early warning operation and / or heating control, optionally, the magnetic detection circuit 30 is specifically configured as follows:
[0065] When the aerosol generating substrate 200 is inserted into the heating position, the coded information is acquired and a first electrical signal is output;
[0066] Or when the aerosol generating substrate 200 leaves the heating position, the coded information is obtained and a second electrical signal is output;
[0067] The main control circuit 40 is specifically configured as follows:
[0068] Determine characteristic information of the aerosol generating substrate 200 based on the first electrical signal, and trigger control of the heating component 13 to heat when the characteristic information matches the preset characteristic information, and trigger control of the heating component 13 not to start heating when the characteristic information does not match the preset characteristic information;
[0069] The heating component 13 is controlled to stop heating based on the second electrical signal.
[0070] In this embodiment, when the aerosol generating matrix 200 is inserted into the heating position corresponding to the accommodating cavity 12, the magnetic detection circuit 30 outputs a first electrical signal with coding information, and the main control circuit 40 obtains the coding information of the magnetic medium 240 through the first electrical signal output by the magnetic detection circuit 30, and compares the characteristic information corresponding to the coding information with the preset characteristic information. When the characteristic information matches the preset characteristic information, it is determined that the aerosol generating matrix 200 is a matching aerosol generating matrix 200, and the main control circuit 40 outputs a heating control signal to the heating component 13, thereby heating the atomized medium of the aerosol generating matrix 200, and at the same time, a corresponding matching indication sound or indicator light can be emitted to inform that it is currently in normal working mode.
[0071] When the aerosol generating matrix 200 is determined to be a non-matching aerosol generating matrix 200 through the characteristic information corresponding to the coding information, the main control circuit 40 can control the heating component 13 to stop heating, and at the same time, issue an alarm through the corresponding indicator sound or indicator light, and report abnormal information.
[0072] When the aerosol generating matrix 200 is pulled out, the magnetic medium 240 with the coded information passes through the magnetic detection circuit 30, and the magnetic detection circuit 30 again outputs a second electrical signal with the coded information to the main control circuit 40. The main control circuit 40 can determine that the aerosol generating matrix 200 is pulled out from the heating device 100 based on the second electrical signal received again. When the matching aerosol generating matrix 200 is pulled out, the main control circuit 40 can control the heating component 13 to stop heating. When the non-matching aerosol generating matrix 200 is pulled out, the main control circuit 40 can stop issuing an alarm and reset the state of the heating device 100.
[0073] In order to improve heating efficiency and safety, optionally, the main control circuit 40 is further configured as follows:
[0074] When the characteristic information matches the preset characteristic information, the temperature curve corresponding to the aerosol generating substrate 200 is determined according to the preset characteristic information, and during the heating process, the temperature of the aerosol generating substrate 200 is controlled to be consistent with the temperature curve over time.
[0075] In this embodiment, a matching preset characteristic information is provided for the aerosol generating matrix 200 matched with the heating device 100. At the same time, the preset characteristic information is matched with the corresponding temperature curve. After the characteristic information of the aerosol generating matrix 200 is obtained, the characteristic information of the aerosol generating matrix 200 is matched with the preset characteristic information. When the two match, it is determined that the aerosol generating matrix 200 is an aerosol generating matrix 200 matched with the heating device 100. The main control circuit 40 obtains the corresponding temperature curve. At the same time, it controls the heating component 13 to start heating, and during the heating process, adjusts the heating temperature of the heating component based on the temperature curve, so that the changing temperature of the aerosol generating matrix follows the changing curve, thereby improving the heating efficiency and safety.
[0076] The heating curve includes temperature parameters that change with time, and the change curve can be set accordingly, and can be rising, falling, etc.
[0077] At the same time, when a heating device 100 can be adapted to multiple aerosol generating substrates 200, each aerosol generating substrate 200 is matched with a preset characteristic information. At the same time, each preset characteristic information is matched with a preset temperature curve. After obtaining the characteristic information corresponding to a matching aerosol generating substrate 200, the corresponding temperature curve can be selected for heating control, thereby improving heating accuracy and safety.
[0078] The main control circuit 40 may include a controller, a processor, a driving circuit, and the like.
[0079] The power supply source of the main control circuit 40, the heating component 13, the pre-magnetization unit 20, and the magnetic detection circuit 30 can be provided by the corresponding power supply module. The power supply module can be set in the heating device 100 or independently set from the heating device 100. The specific setting method of the power supply module is not limited.
[0080] The main control circuit 40, the magnetic detection circuit 30 and the power module can be arranged on the same circuit board, or separately arranged, and the specific arrangement method is not limited.
[0081] The heating device 100 can be a fixed device structure, or a portable device, such as Figure 1As shown, optionally, the heating device 100 further includes a housing 50 , and the heating mechanism 10 , the pre-magnetization unit 20 , the magnetic detection circuit 30 and the main control circuit 40 are arranged in the housing 50 .
[0082] The outer shell 50 is formed by surrounding a sheet of corresponding material, and includes a shell and an upper cover that are adapted to be installed. The upper cover is provided with an opening at a position relative to the opening 11 of the accommodating cavity 12. For the convenience of maintenance, the shell and the upper cover are detachably installed.
[0083] The magnetic medium 240 may be a structure such as magnetic ink or magnetic tape. The magnetic medium 240 may be disposed at a corresponding position of the aerosol generating substrate by printing, polarization, or the like.
[0084] The pre-magnetization unit 20 may be an electromagnetization circuit, a permanent magnet 21, etc. Optionally, the pre-magnetization unit 20 is one of a permanent magnet 21, a magnetic head, and an electromagnet. Figure 3 As shown, the pre-magnetization unit 20 uses a permanent magnet 21 with an N pole and an S pole. The permanent magnet 21 polarizes the magnetic medium 240 so that the magnetic medium 240 carries coded information.
[0085] In order to realize that the magnetic medium 240 transforms a series of binary digital information into a corresponding structure for storing coded information according to a preset distribution rule, before being polarized, the magnetic medium 240 may be polarized to form a magnetic medium segment or a plurality of magnetic medium segments, such as Figure 4 and Figure 5 As shown, after being polarized by the magnetic field, the magnetic medium 240 as a whole is manifested as one or more magnetic medium segments with corresponding magnetic strengths, and is processed by the magnetic detection circuit 30 to generate corresponding pulse signals.
[0086] The magnetic detection circuit 30 can be set at a corresponding position according to the size of the aerosol generating matrix 200, the containing cavity 12 and the pre-magnetization unit 20. The magnetic detection circuit 30 can be separated from the pre-magnetization unit 20 and set on the same straight line, or combined into the same module for use.
[0087] In order to improve the detection accuracy and detection range, the magnetic detection circuit 30 is arranged near the opening 11 of the accommodating cavity 12. In an optional embodiment, as shown in FIG. Figure 1 As shown, the magnetic detection circuit 30 is disposed on the side of the accommodating cavity 12 and is disposed obliquely below the opening 11 .
[0088] Corresponding to the magnetic medium 240, the magnetic detection circuit 30 may adopt a corresponding magneto-electric conversion circuit, such as Figure 6 As shown, optionally, the magnetic detection circuit 30 includes:
[0089] The magnetic sensor 31 is disposed on the accommodating cavity 12 and is configured to convert the coded information of the magnetic medium 240 into an electrical signal;
[0090] The signal processing circuit 32 is connected to the magnetic sensor 31 and is configured to process the electrical signal and output the processed signal to the main control circuit 40 .
[0091] In this embodiment, the magnetic sensor 31 is configured to perform magneto-electric conversion, and obtains corresponding coding information by sensing the polarized magnetic medium 240 on the aerosol generating matrix 200, and converts it into an electrical signal with the coding information. The electrical signal with the coding information is processed by the signal processing circuit 32, such as signal amplification, filtering, rectification, comparison and other processing, and then outputs an electrical signal of a preset amplitude to the main control circuit 40, wherein the electrical signal may be one or more according to the distribution of the magnetic medium 240, and one or more electrical signals are sequentially output to the main control circuit 40 at preset time intervals. The main control circuit 40 determines the characteristic information of the aerosol generating matrix 200 corresponding to the coding information according to the size, number and time interval of the electrical signal, and then performs corresponding heating, early warning and other operations.
[0092] Among them, the specific circuit structure of the signal processing circuit 32 can be set according to needs. Since the electrical signal output by the magnetic sensor 31 is small, in order to meet the signal detection requirements of the main control circuit 40, in an optional embodiment, the signal processing circuit 32 at least includes a signal amplification circuit for amplifying the electrical signal output by the magnetic sensor 31. The signal amplification circuit amplifies the electrical signal output by the magnetic sensor 31 so that it meets the sampling requirements of the main control circuit 40. The signal amplification circuit can adopt structures such as operational amplifiers and transistor amplifier circuits, and the specific circuit structure is not limited.
[0093] Among them, the heating position of the heating component 13 can be set according to the needs, and one heating interval or multiple heating intervals can be set. For example, the middle position of the accommodating chamber 12 is the heating position, and when the aerosol generating matrix 200 reaches the middle position of the accommodating chamber 12 and is a matching aerosol generating matrix 200, the heating is started, and when it leaves the middle position, the heating is stopped. Alternatively, the bottom position of the accommodating chamber 12 is the heating position, and when the aerosol generating matrix 200 reaches the bottom of the accommodating chamber 12, the heating is started, and when it leaves the bottom, the heating is stopped.
[0094] In an optional embodiment, the heating component 13 includes a plurality of heating zones, the plurality of heating zones corresponding to different regions of the accommodating cavity 12, and the plurality of heating zones can work independently or simultaneously;
[0095] The main control circuit 40 is further configured to determine the position of the aerosol generating substrate 200 in the containing chamber 12 according to the electrical signal, and control the operation of the corresponding heating interval according to the position.
[0096] When multiple heating intervals are included, for example, the middle to the bottom of the accommodating chamber 12 is equally or unequally divided into the first heating area to the nth heating area, each area is assigned a heating interval, and each heating interval can correspond to the same heating temperature or different heating temperatures. When the aerosol generating matrix 200 is inserted along the opening of the accommodating chamber 12, the magnetic medium 240 on the aerosol generating matrix 200 is magnetized, and the magnetic medium 240 is accompanied by coded information. During the movement, the magnetic detection circuit 30 outputs a first electrical signal with coded information. At the same time, the main control circuit 40 determines the aerosol according to the change of the first electrical signal. The generating matrix moves to a corresponding heating area or multiple heating areas among the first heating area to the nth heating area, and the main control circuit 40 controls the matching heating intervals to perform separate heating or simultaneous heating according to the position information; and when the aerosol generating matrix 200 is pulled out, for example, when leaving the corresponding heating area or multiple heating areas among the first heating area to the nth heating area, the main control circuit 40 controls the matching one or more heating intervals to stop heating according to the position information, thereby realizing heating control of a single position or multiple positions of the aerosol generating matrix 200, thereby improving heating diversity and heating efficiency.
[0097] Further, in order to reduce the power consumption of the heating device 100 and avoid extra power consumption caused by long-term standby, the heating device 100 optionally includes a low-power working state, and the main control circuit 40 is further configured as follows:
[0098] After the heating device 100 stops heating, if the magnetic detection circuit 30 does not output an electrical signal within a first preset time, the heating device 100 is controlled to enter a low power consumption working state.
[0099] In this embodiment, after the aerosol generating matrix 200 leaves the containing cavity 12 and the heating device 100 stops heating, within the first preset time, when no aerosol generating matrix 200 is inserted into the containing cavity 12, that is, when the magnetic detection circuit 30 does not detect and output the first electrical signal, at this time, the main control circuit 40 controls each module circuit in the heating device 100 to enter a low power consumption working state, and the heating device 100 enters a low power consumption mode to reduce standby power consumption.
[0100] Furthermore, the heating device 100 further includes a start switch, which is connected to the main control circuit 40. The main control circuit 40 controls the heating device 100 to start or stop working by outputting a start signal or a stop signal. At the same time, in order to avoid the aerosol generating substrate 200 being heated for a long time, resulting in damage and generating additional power consumption, the main control circuit 40 is further configured as follows:
[0101] Within the second preset time after the start switch receives the start signal, if no electrical signal output by the magnetic detection circuit 30 is received, the heating device 100 is controlled to enter a low power consumption working state.
[0102] That is, when the heating device 100 is heating the aerosol generating substrate 200, within the second preset time of the heating process, the aerosol generating substrate 200 reaches the heating time, and the aerosol generating substrate 200 maintains the current state, that is, there is no unplugging action, the magnetic detection circuit 30 does not output the second electrical signal. In order to reduce the additional heating power consumption, the main control circuit 40 outputs a shutdown signal to the start switch, controls the heating device 100 to stop heating, and controls the heating device 100 to enter a low power consumption working state, thereby reducing the heating power consumption and improving the heating safety.
[0103] In the low power consumption working state, the magnetic detection circuit 30 remains in the working state and monitors the generation of the first electrical signal or the second electrical signal, that is, monitors whether the aerosol generating substrate 200 is newly inserted or removed. In order to realize the wake-up operation of the heating device 100, optionally, the main control circuit 40 is further configured as follows:
[0104] In the low power working state, the electric signal output by the magnetic detection circuit 30 is received, the low power working state is exited, the working mode is entered, and after receiving the electric signal for a preset time or a preset number of times, the heating component 13 is controlled to perform heating again.
[0105] For example, after the heating device 100 stops heating and after a first preset time, the magnetic detection circuit 30 re-outputs the first electrical signal, indicating that an aerosol generating matrix 200 is currently inserted into the accommodating cavity 12. The main control circuit 40 controls the heating device 100 to exit the low-power working state and enter the working state, and determines the characteristic information of the aerosol generating matrix 200 based on the received first electrical signal, and when the characteristic information matches, controls the heating component 13 to start heating.
[0106] Alternatively, after the second preset time, the aerosol generating matrix 200 is pulled out, and the magnetic detection circuit 30 re-outputs the second electrical signal. At this time, the main control circuit 40 controls the heating device 100 to exit the low power consumption working state and enter the working state.

[0108] The second aspect of the embodiment of the present invention provides an atomization device, including an adapted aerosol generating substrate 200 and a heating device 100;
[0109] The aerosol generating substrate 200 is provided with a magnetic medium 240, which is not magnetized before the aerosol generating substrate 200 is heated for use.
[0110] In this embodiment, the aerosol generating matrix 200 and the heating device 100 are arranged in a plug-in structure. When the aerosol generating matrix 200 is inserted into the heating device 100 and reaches the heating position, the heating device 100 starts heating, and when the aerosol generating matrix 200 is pulled out of the heating position, the heating device 100 stops heating. An aerosol generating matrix 200 is provided with an atomizing medium, and the atomizing medium generates an aerosol when heated.
[0111] Among them, the aerosol generating matrix 200 is also provided with a magnetic medium 240, and the magnetic medium 240 is distributed in accordance with a preset distribution rule through a certain coding method. The magnetic medium 240 is not magnetized before the aerosol generating matrix 200 is heated and used. The magnetic medium 240 is non-magnetic or weakly magnetic. When the magnetic medium 240 is in direct or indirect contact with the magnetic detection circuit 30, no electrical signal is generated or a weak electrical signal is generated, and the characteristic information cannot be determined and identified.
[0112] The shape of the aerosol generating matrix 200 can be set according to the needs, for example, a cylindrical structure. The magnetic medium 240 can adopt structures such as magnetic ink and magnetic tape. The magnetic medium 240 can be set at the corresponding position of the aerosol generating matrix by printing, polarization, etc.
[0113] Alternatively, if Figure 2As shown, the aerosol generating matrix 200 includes a medium segment 210, a filter segment 230 and a support segment 220 connecting the medium segment 210 and the filter segment 230, the medium segment 210 is provided with an atomizing medium, the support segment 220 is provided with a magnetic medium 240 with coding information, the filter segment 230 is provided with a filter element assembly for filtering out aerosol impurities, the medium segment 210 is provided with an atomizing medium, the support segment 220 is provided with a magnetic medium 240 with coding information, and the magnetic medium 240 converts a series of binary digital information into magnetic signals of corresponding polarity according to a preset distribution rule.
[0114] like Figure 2 As shown, the magnetic medium 240 can be disposed on the inner or outer surface of the support section 220, or as shown in FIG. Figure 7 As shown, the magnetic medium 240 can also be integrally arranged with the support segment 220, and the magnetic medium 240 serves as a part of the support segment 220 to form an integrated support segment 220, and the specific arrangement method is not limited.
[0115] A third aspect of the present invention provides a heating method, which is applicable to the above-mentioned heating device 100. Figure 8 As shown, the heating method includes:
[0116] The magnetic medium 240 is magnetized by the pre-magnetization unit 20 so that the magnetic medium 240 carries the coded information;
[0117] When the aerosol generating substrate 200 is inserted into or removed from the containing cavity 12, the magnetic detection circuit 30 obtains the coded information and converts the output electrical signal;
[0118] The main control circuit 40 determines characteristic information of the aerosol generating substrate 200 according to the electrical signal, and triggers the heating component 13 to start heating or stop heating according to the characteristic information.
[0119] In this embodiment, a pre-magnetization unit 20 is arranged near the opening 11 of the accommodating cavity 12 or at other positions of the accommodating cavity 12. The pre-magnetization unit 20 magnetizes the magnetic medium 240 so that the magnetic medium 240 carries coded information. The pre-magnetization unit 20 has magnetism. By magnetizing the magnetic medium 240, that is, polarizing it, the magnetic medium 240 presents an N pole and / or an S pole. The magnetic medium 240 carries coded information. The polarized magnetic medium 240 converts a series of binary digital information into a magnetic signal of corresponding polarity according to a preset distribution rule. For example, the polarized magnetic medium 240 includes an N-pole magnetic medium segment and an S-pole magnetic medium segment. The N-pole magnetic medium segment and the S-pole magnetic medium segment are alternately distributed. At the same time, the width and alternation of the N-pole magnetic medium segment and the S-pole magnetic medium segment are set in accordance with the binary digital information. The N-pole magnetic medium segment outputs a magnetic signal corresponding to "1", and the S-pole magnetic medium segment outputs a magnetic signal corresponding to "0".
[0120] At the same time, a magnetic detection circuit 30 is arranged on the accommodating chamber 12 or relative to the accommodating chamber 12, and the distance between the magnetic detection circuit 30 and the opening 11 of the accommodating chamber 12 is greater than the distance between the pre-magnetization unit 20 and the opening 11 of the accommodating chamber 12. After magnetization, the magnetic medium 240 is accompanied by coding information. When the aerosol generating matrix 200 is inserted into the accommodating chamber 12, the magnetic medium 240 with the coding information passes through the magnetic detection circuit 30, and the magnetic detection circuit 30 senses the magnetic signal of the magnetic medium 240 and outputs an electrical signal with the coding information. The main control circuit 40 records the coding information through the electrical signal and identifies the characteristic information of the aerosol generating matrix 200 corresponding to the coding information, and determines whether it is an aerosol generating matrix 200 matching the atomization device, and performs corresponding early warning operations and heating control.
