[0056] Please refer to Figures 1-5 , an embodiment of the present application provides a detection method, a detection device 800, an aerosol generating device 1000, and a storage medium.

[0057] The detection method of the embodiment of the present application is used for the aerosol generating device 1000. The aerosol generating device 1000 includes a heating pot body 10, a first electrode 110, and a second electrode 120. The heating pot body 10 forms a receiving cavity 101 for receiving an aerosol forming matrix 20. The first electrode 110 and the second electrode 120 are spaced apart and arranged outside the receiving cavity 101.

The comparison module 82 is configured to compare the real-time power supply parameters with preset parameters. The confirmation module 83 is configured to confirm whether the discharge of the first electrode 110 and the second electrode 120 is abnormal according to the comparison result.

[0063] Please refer to Figures 3-5 , an embodiment of the present application provides an aerosol generating device 1000. The aerosol generating device 1000 includes a memory 91 and a processor 92 connected to the memory 91. The memory 91 is configured to store a computer program.

[0064] In the detection method, the detection device 800, and the aerosol generating device 1000 according to the embodiments of the present application, by acquiring the real-time power supply parameters of the power supply 760, comparing the real-time power supply parameters of the power supply 760 with preset parameters, and detecting whether the discharge of the first electrode 110 and the second electrode 120 is abnormal based on the comparison result, the discharge conditions of the first electrode 110 and the second electrode 120 can be detected by avoiding the high-temperature area between the first electrode 110 and the second electrode 120 without adding detection structural components, ensuring the normal formation of aerosols, reducing the risk of abnormal discharge, and further improving the reliability of the aerosol generating device 1000. The detection method according to the embodiments of the present application is relatively simple, has high feasibility and reliability of detection results, and low cost.

[0065] In the embodiment of the present application, the aerosol generating device 1000 refers to a device that can generate aerosols by using an aerosol-forming substrate 20. The aerosol-forming substrate 20 is a processed product of the flowers, stems, or leaves of plants that can generate aerosols after heating. An aerosol is a colloid formed by the distribution of solid or liquid particles in a gaseous medium. The user can inhale the aerosol into the mouth, nasal cavity, or lungs through the mouth or nose, and the aerosol inhaled into the user's respiratory system can be used for various purposes such as food, medicine, and health care.

[0066] Specifically, the bottom of the heating pot bottom 11 may be closed and form the pot bottom 11. An opening 102 may be formed at one end of the heating pot body 10 opposite to the pot bottom 11, and the end forming the opening 102 is the top of the heating pot body 10. In this application, the direction from the opening 102 of the heating pot body 10 to the pot bottom 11 is defined as the direction from top to bottom, and the direction from the center of the opening 102 to the geometric center of the pot bottom 11 is defined as the axial direction of the heating pot body 10, that is, the vertical direction of the heating pot body 10 and the aerosol generating device 1000.

[0067] The heating pot body 10 includes a side wall 12 and a pot bottom 11 connected to the side wall 12, and the pot bottom 11 and the side wall 12 define a receiving cavity 101. The side wall 12 can surround the central axis of the heating pot body 10, and extend along the axial direction of the heating pot body 10 to connect the pot bottom 11 and the opening 102. The outer surface 103 of the heating pot body 10 includes a pot bottom surface 1031 and an outer peripheral surface 1032 connected to the pot bottom surface 1031. The pot bottom surface 1031 is a side surface of the pot bottom 11 away from the receiving cavity 101. The outer peripheral surface 1032 is connected to the outer contour edge of the pot bottom surface 1031, and can extend upward from the pot bottom 11 along the axial direction of the heating pot body 10 to the opening 102.

[0068] It should be noted that arc discharge is a gas discharge phenomenon, which is a process in which the gas between the electrode 150 pair is ionized to form plasma under the action of a strong electric field, that is, an arc. The generation of the arc is accompanied by dazzling brilliance and a large amount of heat. The first electrode 110 and the second electrode 120 are arranged at intervals, and high voltage electricity is applied to the first electrode 110 and the second electrode 120, which can ionize the gas in the interval between the first electrode 110 and the second electrode 120 to generate an arc. The heat of the arc can rapidly heat the heating pot body 10 to a higher temperature, and heat the aerosol-forming matrix 20 in the accommodating cavity 101, so that it is atomized to form an aerosol. It can be understood that during the discharge process, the temperature of the first electrode 110 and the second electrode 120 will also rise, and provide a certain amount of heat to the atomization of the aerosol-forming matrix 20.

[0069] It should also be noted that, when the first electrode 110 and the second electrode 120 are powered on, discharge will occur between the two ends with the shortest distance to generate an arc. Since the arc is generated by breaking through the gas, the shortest distance is the shortest distance between the end of the first electrode 110 and the end of the second electrode 120 along the outer surface 103 of the heating pot body 10, rather than the straight-line distance between the first electrode 110 and the second electrode 120. The two ends of the first electrode 110 and the second electrode 120 with the shortest connecting line on the outer surface 103 of the heating pot body 10 are the discharge ends 140, and the arc is generated between the discharge ends 140 of the first electrode 110 and the second electrode 120.

[0070] The power supply 760 may include a battery 720 and a transformer 710. The battery 720 may be connected to the primary input terminal of the transformer 710 to provide low-voltage direct current. The transformer 710 may convert the primary low voltage into secondary high voltage. The conductive parts 130 of the first electrode 110 and the second electrode 120 may be connected to the secondary output terminal of the transformer 710 to conduct the secondary voltage of the transformer 710 and break down the air gap to form an arc.

[0071] In step S10, the real-time power supply parameters of the power supply 760 include, but are not limited to, the primary side voltage of the transformer 710, the secondary side voltage of the transformer 710, the current of the circuit connected to the first electrode 110 or the second electrode 120, the equivalent resistance of the first electrode 110 or the second electrode 120, etc.

[0072] The heating pot body 10 is detachably installed in the aerosol generating device 1000. The heating pot body 10 can be removed and reinstalled when cleaning or replacement is needed. After the heating pot body 10 is replaced or reinstalled, since the discharge ends 140 of the first electrode 110 and the second electrode 120 are close to or abut against the outer surface 103 of the heating pot body 10, an arc is generated along the outer surface 103. The position of the heating pot body 10 directly affects the arc length and the generation position of the arc. The real-time power supply parameters of the power supply 760 are affected by the arc length. For example, when the arc length increases, the secondary voltage of the transformer 710 increases.

[0073] In step S20, the preset parameters may be the power supply parameters of the power supply 760 when the relative positions of the heating pot body 10, the first electrode 110, and the second electrode 120 are correct. The relative positions of the heating pot body 10, the first electrode 110, and the second electrode 120 being correct may mean that the discharge ends 140 of the first electrode 110 and the second electrode 120 are close to or abut against the outer surface 103 of the heating pot body 10, and the arc generated when the first electrode 110 and the second electrode 120 are energized adheres to the bottom of the pot 11, and the aerosol forming matrix 20 can be quickly heated and atomized to form an aerosol, and the heating is relatively sufficient and uniform. For example, the discharge end 140 of the first electrode 110 may surround the heating pot body 10, the second electrode 120 may be provided at the bottom of the pot 11 and the discharge end 140 of the second electrode 120 abuts against the center of the bottom of the pot 11. Another example is that the first electrode 110 and the second electrode 120 may be distributed along the radial direction of the heating pot body 10 on the side wall of the heating pot body 10, and the shortest connection line between the first electrode 110 and the second electrode 120 passes through the center of the bottom of the pot 11.

[0074] The electrode 150 includes a first electrode 110 and a second electrode 120. When the relative positions of the heating pot body 10 and the electrode 150 are correct, the distance between the discharge ends 140 of the first electrode 110 and the second electrode 120 is within a predetermined range, and the arc length of the formed arc is also within a predetermined arc length range. Comparing the real-time power supply parameters of the comparison power supply 760 with the preset parameters, the generated deviation does not exceed a predetermined threshold. For example, when the first electrode 110 and the second electrode 120 are energized, an arc is generated along the connection line passing through the center of the bottom of the pot 11 at the two discharge ends 140, and the secondary voltage of the transformer 710 is measured as a predetermined parameter. The secondary voltage value of the transformer 710 is relatively high.

[0075] In step S30, when the heating pot body 10, the first electrode 110, and the second electrode 120 are in the correct relative positions, the first electrode 110 and the second electrode 120 discharge normally. When the heating pot body 10, the first electrode 110, and the second electrode 120 are not in the correct relative positions, the arc length and arc position generated by the first electrode 110 and the second electrode 120 are abnormal, and the discharge of the first electrode 110 and the second electrode 120 is abnormal. For example, when the heating pot body 10 is not installed or reinstalled in the incorrect position, it may be that the bottom of the pot 11 is higher than the discharge ends 140 of the first electrode 110 and the second electrode 120, resulting in an arc being generated by the first electrode 110 and the second electrode 120 discharging along a shorter connection line. At this time, the secondary voltage of the transformer 710 is significantly lower than the predetermined parameter.

[0076] In the case of reinstalling or replacing the heating pot body 10, by comparing the real-time power supply parameters and the preset parameters, the consistency of the position and arc length of the discharge arc between the first electrode 110 and the second electrode 120 is ensured, thereby ensuring the consistency of the heating and atomization of the aerosol-forming matrix 20.

[0077] The bottom of the pot 11 of the heating pot body 10 can be a round-bottom structure, and the bottom of the pot 11 can protrude downward along the axial direction of the heating pot body 10. In some embodiments, the inner and outer contours at the center of the bottom of the pot 11 are both arc-shaped, and the connection between the bottom of the pot 11 and the side wall 12 is connected and transitioned by an arc. The bottom surface of the pot 1031 can be an overall arc surface, or the bottom surface of the pot 1031 can be a flat surface at the center or the edge and is transitionally connected by an arc surface. The radius of curvature of the bottom surface of the pot 1031 is not limited. The bottom of the pot being a round-bottom structure that protrudes downward makes the influence of the position change of the heating pot body on the arc length more obvious. Therefore, when the position of the heating pot body changes, the deviation of the real-time power supply parameters of the power supply relative to the predetermined parameters is more significant, which is convenient for comparison and is beneficial to improving the detection accuracy.

[0078] Please refer to Figure 6 , in some embodiments, based on the comparison result, confirming whether the discharge of the first electrode 110 and the second electrode 120 is abnormal includes:

[0079] Step S31, when the deviation between the real-time power supply parameters and the preset parameters exceeds the preset threshold, confirm that the first electrode 110 and the second electrode 120 discharge abnormally;

[0080] Step S32, when the deviation between the real-time power supply parameters and the preset parameters does not exceed the preset threshold, confirm that the first electrode 110 and the second electrode 120 discharge normally.

[0081] In some embodiments, the confirmation module 83 is configured to confirm that the first electrode 110 and the second electrode 120 discharge abnormally when the deviation between the real-time power supply parameters and the preset parameters exceeds the preset threshold, and is configured to confirm that the first electrode 110 and the second electrode 120 discharge normally when the deviation between the real-time power supply parameters and the preset parameters does not exceed the preset threshold.

[0082] In some embodiments, the processor 92 is configured to confirm that the first electrode 110 and the second electrode 120 discharge abnormally when the deviation between the real-time power supply parameters and the preset parameters exceeds the preset threshold, and is configured to confirm that the first electrode 110 and the second electrode 120 discharge normally when the deviation between the real-time power supply parameters and the preset parameters does not exceed the preset threshold.

[0083] In this way, by detecting the real-time power supply parameters, comparing whether the deviation between the real-time power supply parameters and the preset parameters exceeds the preset threshold, and then detecting whether the first electrode 110 and the second electrode 120 discharge normally, information is fed back to the user or the aerosol generating device 1000, and protection control is performed on the heating atomization device.

[0084] Specifically, the preset threshold of the deviation between the real-time power supply parameters and the preset parameters can be 50% of the preset parameters. When the deviation between the real-time power supply parameters and the preset parameters is greater than 50% of the preset parameters, confirm that the first electrode 110 and the second electrode 120 discharge abnormally. When the deviation between the real-time power supply parameters and the preset parameters is less than or equal to 50% of the preset parameters, confirm that the first electrode 110 and the second electrode 120 discharge normally.

[0085] Please refer to Figure 5, in some embodiments, the first electrode 110 and the second electrode 120 can be movably arranged relative to the heating pot body 10, and the first electrode 110 and the second electrode 120 can move relative to each other to adjust the distance between the discharge ends 140. For example, the heating pot body 10 is installed in the aerosol generating device 1000, and the bottom 11 of the pot is located between the first electrode 110 and the second electrode 120. The first electrode 110 and the second electrode 120 move away from each other along the radial direction of the heating pot body 10 as the heating pot body 10 is inserted, and the distance between the discharge end 140 of the first electrode 110 and the discharge end 140 of the second electrode 120 increases. Another example is that the second electrode 120 is located at the bottom 11 of the pot, and the second electrode 120 moves downward along the axial direction of the heating pot body 10 as the heating pot body 10 is inserted, and the distance between the discharge end 140 of the first electrode 110 and the discharge end 140 of the second electrode 120 increases. The power supply parameter of the initial power supply 760 before the heating pot body 10 is disassembled can be used as a predetermined parameter, and the power supply parameter of the power supply 760 after the heating pot body 10 is reinstalled is the real-time discharge parameter. In this embodiment, the arc length of the arc increases as the distance between the discharge ends 140 increases, and the preset threshold value of the deviation between the real-time power supply parameter and the preset parameter can be increased accordingly to improve the accuracy of the comparison result.

[0086] Please refer to Figure 4 and Figure 6 , in some embodiments, the real-time power supply parameter includes the real-time primary side voltage of the transformer 710 of the power supply 760. The step S31, when the deviation between the real-time power supply parameter and the preset parameter exceeds the preset threshold, to confirm that the first electrode 110 and the second electrode 120 discharge abnormally, includes:

[0087] Step S310, when the deviation between the real-time primary side voltage and the preset voltage exceeds the preset voltage threshold, to confirm that the first electrode 110 and the second electrode 120 discharge abnormally.

[0088] The step S32, when the deviation between the real-time power supply parameter and the preset parameter does not exceed the preset threshold, to confirm that the first electrode 110 and the second electrode 120 discharge normally, includes:

[0089] Step S320, when the deviation between the real-time primary side voltage and the preset voltage does not exceed the preset voltage threshold, to confirm that the first electrode 110 and the second electrode 120 discharge normally.

[0090] In some embodiments, the confirmation module 83 is used to confirm that the first electrode 110 and the second electrode 120 discharge abnormally when the deviation between the real-time primary side voltage and the preset voltage exceeds the preset voltage threshold, and is used to confirm that the first electrode 110 and the second electrode 120 discharge normally when the deviation between the real-time primary side voltage and the preset voltage does not exceed the preset voltage threshold.

[0091] In some embodiments, the processor 92 is configured to confirm that the first electrode 110 and the second electrode 120 are discharging abnormally when the deviation between the real-time primary side voltage and the preset voltage exceeds the preset voltage threshold, and to confirm that the first electrode 110 and the second electrode 120 are discharging normally when the deviation between the real-time primary side voltage and the preset voltage does not exceed the preset voltage threshold.

[0092] Specifically, the power supply 760 includes a battery 720 and a transformer 710. The battery 720 provides a low-voltage direct current. The primary side of the transformer 710 is the input side of the voltage, and the secondary side of the transformer 710 is the output side of the voltage after being converted by the transformer 710. The primary side of the transformer 710 is connected to the battery 720, and the primary side voltage of the transformer 710 is a low voltage, which is convenient for detection. The secondary side of the transformer 710 is connected to the first electrode 110 and the second electrode 120, and the secondary side voltage is converted into a high voltage by the transformer 710. The secondary side voltage of the transformer 710 changes in real time according to the discharging states of the first electrode 110 and the second electrode 120 during the discharging process of the first electrode 110 and the second electrode 120. There is a certain proportional relationship between the primary side voltage and the secondary side voltage and it changes with the secondary side voltage. Therefore, the real-time discharging states of the first electrode 110 and the second electrode 120 can be confirmed by detecting the real-time primary side voltage. When the first electrode 110 and the second electrode 120 are discharging normally, the value of the primary side voltage of the transformer 710 is the preset voltage. The preset voltage threshold can be 50% of the preset voltage.

[0093] In step S310, when the absolute value of the difference between the real-time primary side voltage and the preset voltage is greater than 50% of the preset voltage, it is confirmed that the first electrode 110 and the second electrode 120 are discharging abnormally.

[0094] In step S320, when the absolute value of the difference between the real-time primary side voltage and the preset voltage is less than or equal to 50% of the preset voltage, it is confirmed that the first electrode 110 and the second electrode 120 are discharging normally.

[0095] Please refer to Figure 8 , in some embodiments, the detection method further includes:

[0096] Step S321, after confirming that the first electrode 110 and the second electrode 120 are discharging normally, controlling the power supply 760 to continue supplying power to the first electrode 110 and the second electrode 120.

[0097] In some embodiments, the detection device 800 further includes a control module 84. The control module 84 is configured to control the power supply 760 to continue supplying power to the first electrode 110 and the second electrode 120 after confirming that the first electrode 110 and the second electrode 120 are discharging normally.

[0098] In some embodiments, the processor 92 is configured to control the power supply 760 to continue supplying power to the first electrode 110 and the second electrode 120 after confirming that the first electrode 110 and the second electrode 120 are discharging normally.

[0099] In this way, through the detection method, after confirming that the first electrode 110 and the second electrode 120 are discharging normally, the power supply 760 continues to supply power to the first electrode 110 and the second electrode 120, which plays a role in starting protection for the aerosol generating device 1000.

[0100] Specifically, the power supply 760 can first provide a relatively small voltage to the first electrode 110 and the second electrode 120 to perform the detection method. And in step S321, after confirming normal discharge, the power supply 760 provides a relatively high voltage to the first electrode 110 and the second electrode 120.

[0101] Please refer to Figure 9 , in some embodiments, the detection method further includes:

[0102] When at least one of the following conditions is met, control the power supply 760 to stop supplying power to the first electrode 110 and the second electrode 120:

[0103] The discharge duration of the first electrode 110 and the second electrode 120 exceeds a predetermined duration;

[0104] The temperature of the heating pot body 10 exceeds a preset temperature;

[0105] The aerosol generating device 1000 has not been puffed within a predetermined time;

[0106] The button 823 of the aerosol generating device 1000 has not been triggered, and the button 823 is electrically connected to the power supply 760.

[0107] In some embodiments, the control module 84 is configured to control the power supply 760 to stop supplying power to the first electrode 110 and the second electrode 120 when at least one of the above conditions is met.

[0108] In some embodiments, the processor 92 is configured to control the power supply 760 to stop supplying power to the first electrode 110 and the second electrode 120 when at least one of the above conditions is met.

[0109] In this way, the detection method of the embodiments of the present application can be used to detect the heating condition of the arc and control the power supply 760 to supply power according to the arc condition, reducing the risk of abnormal operation of the aerosol generating device 1000.

[0110] Specifically, the heating condition of the electric arc can be fed back through conditions such as the discharge duration of the first electrode 110 and the second electrode 120, the temperature of the heating pot 10, the suction state of the aerosol generating device 1000, and whether the button 823 is triggered. When the heating condition of the electric arc cannot reach the predetermined state, that is, when the discharge duration of the first electrode 110 and the second electrode 120 exceeds the predetermined duration, the temperature of the heating pot 10 exceeds the preset temperature, the aerosol generating device 1000 is not sucked within the predetermined time, and the button 823 of the aerosol generating device 1000 is not triggered, one or more of the following conditions are met, indicating that the heating condition of the electric arc is abnormal and the heating needs to be stopped.

[0111] In the case of abnormal arc heating conditions, the power supply 760 stops supplying power to the first electrode 110 and the second electrode 120 , and may prompt abnormal heating condition information at the same time or later.

[0112] See also Figure 7 and Figure 8 In some embodiments, the detection method further comprises:

[0113] Step S311 , after confirming that the first electrode 110 and the second electrode 120 have abnormal discharge, the power supply 760 is controlled to stop supplying power to the first electrode 110 and the second electrode 120 .

[0114] In some embodiments, the control module 84 is used to control the power supply 760 to stop supplying power to the first electrode 110 and the second electrode 120 after confirming that the discharge of the first electrode 110 and the second electrode 120 is abnormal.

[0115] In some embodiments, the processor 92 is configured to control the power supply 760 to stop supplying power to the first electrode 110 and the second electrode 120 after confirming that the discharge of the first electrode 110 and the second electrode 120 is abnormal.

[0116] In this way, the risk of abnormal discharge causing aerosol generation failure and damage to the aerosol generating device 1000 is reduced, thereby protecting the aerosol generating device 1000.

[0117] In step S31, the preset threshold value of the deviation between the real-time power supply parameter and the preset parameter may be 50% of the preset parameter. If the deviation between the real-time power supply parameter and the preset parameter is greater than 50% of the preset parameter, it is confirmed that the first electrode 110 and the second electrode 120 are abnormally discharged. In step S311, after confirming that the first electrode 110 and the second electrode 120 are abnormally discharged, the power supply 760 stops supplying power to the first electrode 110 and the second electrode 120, and no arc is formed between the first electrode 110 and the second electrode 120, which can prevent the arc from being formed in the non-heating area and damaging other structures, and also prevent the user from inhaling ionized gas.

[0118] Please see Continue ReadingFigure 7 and Figure 8 In some embodiments, the detection method further includes:

[0119] Step S312: After confirming that the first electrode 110 and the second electrode 120 have abnormal discharges, a prompt message is sent.

[0120] In certain embodiments, the control module 84 is configured to send a prompt message after confirming that the first electrode 110 and the second electrode 120 have abnormal discharges.

[0121] In certain embodiments, the processor 92 is configured to send a prompt message after confirming that the first electrode 110 and the second electrode 120 have abnormal discharges.

[0122] In this way, sending a prompt message after the first electrode 110 and the second electrode 120 have abnormal discharges can remind the user to adjust the position of the heating pot body 10 so that the first electrode 110 and the second electrode 120 can discharge normally.

[0123] In step S312, sending a prompt message after confirming that the first electrode 110 and the second electrode 120 have abnormal discharges can be executed after step S311, where the power supply 760 is controlled to stop supplying power to the first electrode 110 and the second electrode 120 after confirming that the first electrode 110 and the second electrode 120 have abnormal discharges. Step S312 can also be executed synchronously with step S311.

[0124] Specifically, in combination with Figure 4 , the aerosol generating device 1000 can be provided with a control component 820, and the control component 820 includes a lamp bead 824 and a button 823. The lamp bead 824 can be used to indicate abnormal discharge information. For example, after confirming that the first electrode 110 and the second electrode 120 have abnormal discharges, the lamp bead 824 highlights or flashes in red light to prompt abnormal discharge. The user can confirm that the first electrode 110 and the second electrode 120 have abnormal discharges through information such as the color light, luminous brightness, and luminous frequency of the lamp bead 824, and then adjust the position of the heating pot body 10 so that the position and arc length of the arc between the first electrode 110 and the second electrode 120 are adjusted to the normal range, so that the real-time power supply parameters of the power supply 760 are adjusted to be close to the preset parameters.

[0125] After adjusting the position of the heating pot body 10, the real-time power supply parameters can be obtained again, and the real-time power supply parameters are compared with the preset parameters. If the deviation between the real-time power supply parameters and the preset parameters exceeds a predetermined threshold, the power supply 760 is controlled to stop supplying power to the first electrode 110 and the second electrode 120 again, and a prompt message is sent, and the position of the heating pot body 10 is adjusted until the deviation between the real-time power supply parameters and the preset parameters does not exceed the predetermined threshold, and the power supply 760 continues to supply power to the first electrode 110 and the second electrode 120, and the detection ends.

[0126] Please refer to Figure 10 and Figure 11 , in some embodiments, the detection method includes:

[0127] Step S40, when the microphone 825 or the button 823 of the aerosol generating device 1000 is triggered, confirm that the first electrode 110 and the second electrode 120 are in a discharging state.

[0128] In certain embodiments, the confirmation module 83 is configured to confirm that the first electrode 110 and the second electrode 120 are in a discharging state when the microphone 825 or the button 823 of the aerosol generating device 1000 is triggered.

[0129] In certain embodiments, the processor 92 is configured to confirm that the first electrode 110 and the second electrode 120 are in a discharging state when the microphone 825 or the button 823 of the aerosol generating device 1000 is triggered.

[0130] In this way, detection is performed when it is confirmed that the first electrode 110 and the second electrode 120 are in a discharging state, improving the reliability and accuracy of the detection method.

[0131] Specifically, the step S40 of confirming that the first electrode 110 and the second electrode 120 are in a discharging state when the microphone 825 or the button 823 of the aerosol generating device 1000 is triggered is performed before the step S10 of obtaining the real-time power supply parameters of the power supply 760 when the first electrode 110 and the second electrode 120 are discharging. In combination with Figures 3-5 , the microphone 825 or the button 823 can be provided on the outer shell 610 of the aerosol generating device 1000, and the user can trigger the microphone 825 and / or the button 823 by pressing. The microphone 825 and / or the button 823 can also be provided inside the aerosol production device. For example, the microphone 825 can be provided above the heating pot body 10 and can be triggered when the heating pot body 10 is loaded, thereby starting the detection to confirm whether the loading position of the heating pot body 10 is correct and whether the first electrode 110 and the second electrode 120 are discharging normally.

[0132] In the aerosol generating device 1000 according to the embodiment of the present application, the detection method can detect whether the assembly positions of the heating pot body 10, the first electrode 110, and the second electrode 120 are correct, thereby ensuring that discharging is started when the assembly position of the electrode 150 and the heating pot body 10 is correct, ensuring the consistency of the arc formation position, reducing the risk of damage to the aerosol generating device 1000 due to abnormal discharging, and improving the user experience and safety.
