Description

Technical Field

[0001] This application relates to the field of aerosol technology, and more specifically, to an aerosol generating apparatus, an aerosol generating system, and an insertion detection method. Background Technology

[0002] When determining whether an aerosol product is inserted into an aerosol generating device, the insertion or non-insertion of the aerosol product is usually determined by comparing the sensor signal with a signal threshold (for example, if the sensor signal is greater than the signal threshold, it is determined that the aerosol product has been inserted).

[0003] However, when sensor signals are easily affected by external environmental factors (such as temperature changes, humidity fluctuations, etc.), the sensor signals are prone to fluctuations, leading to misjudgments or repeated fluctuations in judgment. Summary of the Invention

The accommodating element has an accommodating cavity for accommodating an aerosol-generated product. The controller is configured to: acquire multiple detection information collected by the detection electrode, wherein the multiple detection information are acquired by the detection electrode after the aerosol-generated product is inserted into the accommodating cavity; and, based on the detection information, detect whether the aerosol-generated product has been removed from the accommodating cavity.

[0006] In some embodiments, the detection electrodes include one or more, and the step of detecting whether the aerosol generating product has been pulled out based on the detection information includes: determining whether the difference between the detection information of each detection electrode and the corresponding preset pull-out threshold is greater than a preset difference threshold and lasts for a preset duration; if so, then it is determined that the aerosol generating product has been pulled out.

[0007] In some embodiments, the detection electrode includes one or more, and the plurality of detection electrodes are respectively disposed at different positions of the receiving member. The step of detecting whether the aerosol generating product has been pulled out based on the detection information includes: determining whether the difference between the detection information of each detection electrode and the corresponding preset pull-out threshold is greater than a preset difference threshold and lasts for a preset duration; if so, determining whether the time sequence of each detection electrode reaching the corresponding preset pull-out threshold matches the position sequence of each detection electrode; if the time sequence matches the position sequence, determining that the aerosol generating product has been pulled out.

[0008] In some embodiments, the step of detecting whether the aerosol-generating product has been pulled out based on the detection information further includes: detecting whether the detection information has a sudden change; if so, obtaining the suction detection result within a preset time period including the time when the detection information has a sudden change; if the suction detection result indicates that a suction action has been detected, determining that the aerosol-generating product has not been pulled out; if the suction detection result indicates that no suction action has been detected, proceeding to the step of determining whether the detection information of each of the detection electrodes is greater than the corresponding preset pull-out threshold and continues for a preset duration.

[0009] In some embodiments, detecting whether the aerosol-generating product has been pulled out based on the detection information includes: detecting whether the detection information has abruptly changed; if so, obtaining a suction detection result within a preset time period including the moment when the detection information abruptly changed; if the suction detection result indicates that a suction action was detected, determining that the aerosol-generating product has not been pulled out; if the suction detection result indicates that no suction action was detected, determining that the aerosol-generating product has been pulled out.

[0010] In some embodiments, the controller is further configured to: detect whether the changing trend of the detection information meets a preset trend; if yes, determine that a suction action has been detected; if no, determine that a suction action has not been detected.

[0011] In some embodiments, the aerosol generating apparatus further includes a suction detection element for performing suction detection to obtain the suction detection result.

[0012] In some embodiments, the detection electrode includes a first detection electrode and a second detection electrode, which are respectively disposed at different positions in the accommodating member; when the aerosol generating article is not inserted into the accommodating cavity, the detection information collected by the first detection electrode and the second detection electrode may be the same or different; when the aerosol generating article is inserted into the accommodating cavity, the detection information collected by the first detection electrode and the second detection electrode may be different.

[0013] This application also proposes an aerosol generation system, including an aerosol generation article and an aerosol generation device as described in any of the above embodiments.

[0014] This application also proposes a detection method for an aerosol generating device, the aerosol generating device including a receiving element, a detection electrode, and a controller, wherein the receiving element has a receiving cavity; the receiving cavity is used to contain an aerosol generating product; the method includes: acquiring multiple detection information collected by the detection electrode, wherein the multiple detection information are collected by the detection electrode after the aerosol generating product is inserted into the receiving cavity; and detecting whether the aerosol generating product has been removed based on the detection information.

[0015] This application also proposes a non-volatile computer-readable storage medium containing a computer program, characterized in that, when the computer program is executed by a processor, the processor performs the insertion detection method described in any of the above embodiments.

The aerosol generating apparatus includes a receiving component, a detection electrode, and a controller. The receiving component has a receiving cavity for accommodating the aerosol generating product. The controller acquires multiple detection information collected by the detection electrode after the aerosol generating product is inserted into the receiving cavity, thereby monitoring the state of the aerosol generating product within the receiving cavity and providing real-time information on the insertion, use, and removal status of the aerosol generating product within the receiving cavity. Based on the detection information, the controller detects whether the aerosol generating product has been removed from the receiving cavity, improving the removal recognition rate of the aerosol generating product. Due to the high precision and high sensitivity of the detection electrode, the detection accuracy of the insertion and removal of the aerosol generating product can be guaranteed. Furthermore, even under the influence of external environmental factors (e.g., temperature changes, humidity fluctuations, etc.), the detection electrode can still stably output detection information, effectively preventing misjudgments caused by environmental factors, shaking or rotation of the aerosol generating product, etc., thus improving the user experience.

Detailed Implementation

[0034] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting the embodiments of this application.

[0035] To facilitate understanding of this application, the following explanations are provided for the terms and background information used in this application:

[0036] In related technologies, when detecting whether an aerosol product of a heat-not-burn (HNB) appliance (e.g., an electronic cigarette device) is inserted into the HNB appliance, a sensor (such as a photoelectric sensor) is usually set for the HNB appliance. A fixed signal threshold is then set, and the aerosol product is determined to be inserted into or not inserted into the HNB appliance by comparing the sensor signal with the signal threshold (e.g., if the sensor signal is greater than the signal threshold, it is determined that the aerosol product has been inserted).

[0037] However, when the difference between the sensor signals in the inserted and non-inserted states is small, or when the sensor signals are easily affected by external environmental factors (such as temperature changes, humidity fluctuations, etc.), the sensor signals are prone to fluctuations, leading to misjudgments or repeated fluctuations in judgment. Furthermore, since aerosol products generate a large amount of aerosol during heating, and a large amount of aerosol is also carried away during suction, and some sensors can also respond to changes in aerosol and output sensor signals, if the sensor changes caused by aerosol generation and suction meet the removal judgment conditions, misjudgments are likely to occur, leading to interruption of appliance heating, waste of aerosol products, and negatively impacting the user experience.

[0038] To address the aforementioned technical problems, this application provides an aerosol generating apparatus.

[0039] The application scenarios of the technical solution in this application will be introduced below. Please refer to [link / reference]. Figure 1This application provides an aerosol generation system 1000, which includes an aerosol generation device 100 and an aerosol generation product 200. The aerosol generation device 100 includes a accommodating member 101, a detection electrode 102, and a controller 103. The accommodating member 101 has an accommodating cavity 104 for accommodating and fixing the aerosol generation product 200. The aerosol generation device 100 can heat the aerosol generation product 200 to obtain aerosol.

[0040] The aerosol generating device 100 can be an apparatus or equipment capable of processing (such as heating) the aerosol generating product 200 to obtain aerosol.

[0041] The aerosol generating product 200 includes a front end 201, a medium section 202, and a functional section 203. The medium section 202 is located between the front end 201 and the functional section 203. The medium section is heated to generate aerosol.

[0042] The functional segment 203 may include at least one of the support segment 2031 and the filter segment 2032. For example, the functional segment 203 may include the filter segment 2032 and the support segment 2031, with the support segment 2031 located between the medium segment 202 and the filter segment 2032; or, for another example, the functional segment 203 may include the filter segment 2032; or, for yet another example, the functional segment 203 may include the support segment 2031. This application does not impose any limitations on these aspects.

[0043] Optionally, functional segment 203 may also include at least one of a cooling segment, a support segment, and a filter segment; or, the support segment may also serve as a cooling segment.

[0044] Optionally, the detection electrode 102 may include a detection capacitor.

[0045] Optionally, the detection electrode 102 may include a first detection electrode 1021 and a second detection electrode 1022, with the first detection electrode 1021 and the second detection electrode 1022 respectively disposed at different positions in the accommodating member 101.

[0046] For example, the first detection electrode 1021 can be disposed in the accommodating member 101, opposite to the position of the front end member 201 when the aerosol generating product 200 is inserted into the accommodating cavity 104, and the second detection electrode 1022 can be disposed opposite to the position of the support section 2031.

[0047] Optionally, the detection electrode 103 includes a first detection electrode 1031 and a second detection electrode 1032, which are respectively disposed at different positions in the accommodating member. When the aerosol generating product 200 is not inserted into the accommodating cavity, the detection information collected by the first detection electrode 1031 and the second detection electrode 1032 may be the same or different. When the aerosol generating product 200 is inserted into the accommodating cavity, the detection information collected by the first detection electrode 1031 and the second detection electrode 1032 may be different.

[0048] For example, when the aerosol generating article 200 is not inserted into the receiving cavity, the detection information of the first detection electrode 1031 and the second detection electrode 1032 is collected based on air, so the detection information collected by the first detection electrode 1031 and the second detection electrode 1032 can be the same; as another example, when the aerosol generating article 200 is inserted into the receiving cavity 104, the detection information of the first detection electrode 1031 and the second detection electrode 1032 is generated based on different parts of the aerosol generating article 200, so the detection information collected by the first detection electrode 1031 and the second detection electrode 1032 is different.

[0049] Optionally, the aerosol generating device 100 may also include a suction detection element 105, which may be such as a third detection electrode 105, a temperature detection element, etc.

[0050] Optionally, the controller 103 may be a microcontroller unit (MCU) (a microcomputer chip that integrates multiple functions such as a central processing unit (CPU), memory, and input / output (I / O) interfaces), a digital signal processor (DSP) (a controller for digital signal processing), etc.

[0051] Optionally, please refer to Figure 3 The aerosol generating device 100 may include a detection module 301, a suction detection module 302, and a control module 303.

[0052] The detection module 301 can be used to acquire and analyze detection information after the aerosol-generated product 200 is inserted into the receiving cavity 104; the suction detection module 302 can be used to detect whether the user has performed suction (for example, it can be used to identify the user's suction action and suction time); the control module 303 can be used to control the various components or modules of the aerosol generating device. The detection module 301 can output multiple detection information to the control module 303, and the control module 303 determines whether the aerosol-generated product 200 has been removed from the receiving cavity 104 based on the multiple detection information; the suction detection module 302 can output multiple suction information to the control module 303, and the control module 303 can obtain the suction detection result by analyzing the suction information.

[0053] Optionally, each module can be a functional control module or a hardware module. For example, the detection module 301 may include a first detection module 3011 and a second detection module 3012. The first detection module 3011 may be one of the first detection electrode 1031 and the second detection electrode 1032, and the second detection module 3012 may be the other (e.g., Figure 3 As shown, the first detection module 3011 is disposed on the receiving member 101, located opposite the bottom of the receiving cavity 104, and the second detection module 3012 is disposed on the receiving member 101, located opposite the top of the receiving cavity 104; or, the first detection module 3011 may be a functional control module connected to one of the first detection electrode 1031 and the second detection electrode 1032, and the second detection module may be a functional control module connected to the other. For example, as... Figure 3 As shown, the suction detection module 302 can be a capacitive sensor installed in the airway of the aerosol generating device 100 (based on the capacitive signal output by the capacitive sensor, it determines whether suction has occurred); for example, the control module 303 can be the controller 104 of the aerosol generating device 100.

[0054] The aerosol generating apparatus 100 of this application will now be described in detail:

[0055] This application provides an aerosol generating apparatus 100. Please refer to [link to relevant documentation]. Figures 1 to 4 The aerosol generating device 100 includes a housing 101, a detection electrode 102, and a controller 103. The housing 101 has a housing cavity 104 for accommodating the aerosol generating product 200. The controller 103 can be used to execute a detection method, wherein the detection method includes:

[0056] Step 011: Acquire multiple detection information collected by the detection electrode 102. The multiple detection information is collected by the detection electrode 102 after the aerosol generating product 200 is inserted into the accommodating cavity 104.

[0057] Step 012: Based on the detection information, detect whether the aerosol-generated product 200 has been removed from the accommodating cavity 104.

[0058] The detection electrode 102 can sense the presence of the aerosol-generating product 200 within the accommodating cavity 104 and convert it into detection information. This detection information can be, for example, capacitance, voltage, or current values.

[0059] Optionally, the detection electrode 102 can be a capacitive detection sensor, an optical detection sensor, etc.

[0060] Specifically, the aerosol generating device 100 includes a receiving element 101, a detection electrode 102, and a controller 103. The receiving element 101 has a receiving cavity 104 for accommodating the aerosol generating product 200. The aerosol generating device 100 can heat the aerosol generating product 200 placed in the receiving cavity 104, enabling the aerosol generating product 200 to generate aerosols. The detection electrode 102 can collect information (e.g., capacitance value) at the location opposite to the detection electrode 102 within the receiving cavity 104. After the aerosol generating product 200 is inserted into the receiving cavity 104, multiple detection information continuously collected by the detection electrode 102 can be transmitted to the controller 103. After acquiring multiple detection information, the controller 103 analyzes the information (e.g., detecting changes in multiple detection information based on time sequence; or, for example, comparing multiple detection information with a preset threshold, etc.) to monitor whether the aerosol generating product 200 has been removed from the receiving cavity 104.

[0061] More specifically, for example, taking the example where the detection electrode 102 includes a capacitance detection sensor and the detection information includes capacitance value, after the aerosol generating product 200 is inserted into the receiving cavity 104, assuming that the aerosol generating device 100 does not heat the aerosol generating product 200, the presence of the aerosol generating product 200 itself will affect the electric field in the receiving cavity 104, that is, change the first capacitance value detected by the capacitance detection sensor. After the aerosol generating product 200 is removed from the receiving cavity 104, the detection information detected by the capacitance detection sensor includes the second capacitance value of air (assuming that the capacitance value of air is greater than the capacitance value of the aerosol generating product 200). Based on the comparison of multiple detection information and preset conditions (e.g., the comparison of the change threshold from the first capacitance value to the second capacitance value and the preset threshold, etc.), it can be determined whether the aerosol generating product 200 has been removed from the receiving cavity 104.

[0062] For example, taking the detection electrode 102 as including a capacitance detection sensor and the detection information including capacitance value as an example, after the aerosol generating product 200 is inserted into the receiving cavity 104, assuming that the aerosol generating device 100 heats the aerosol generating product 200, the aerosol generating product 200 generates aerosol, and the aerosol accumulates in the receiving cavity 104, the detection information detected by the capacitance detection sensor is affected by the accumulated aerosol and the aerosol generating product 200 itself, and the detection information can be reflected as an increasing capacitance value. When the aerosol generating product 200 is removed from the receiving cavity 104, the accumulated aerosol will be carried out along with the aerosol generating product 200. At this time, the direction of change of the detection information detected by the capacitance detection sensor will be opposite to the direction of aerosol accumulation. Therefore, by analyzing multiple detection information, it can be determined whether the aerosol generating product 200 has been removed from the receiving cavity 104.

[0063] Thus, the aerosol generating device 100 includes a receiving element 101, a detection electrode 102, and a controller 103. The receiving element 101 has a receiving cavity 104 for accommodating the aerosol generating product 200. The controller 103 is used to acquire multiple detection information collected by the detection electrode 102 after the aerosol generating product 200 is inserted into the receiving cavity 104, to monitor the state of the aerosol generating product 200 within the receiving cavity 104. Based on the detection information, the aerosol is detected. Whether the generated product 200 has been removed from the receiving cavity 104 is determined, which improves the removal recognition rate of the aerosol generated product 200. Due to the high precision and high sensitivity of the detection electrode 102, the insertion and removal detection accuracy of the aerosol generated product 200 can be guaranteed. Moreover, even under the influence of external environmental factors (such as temperature changes, humidity fluctuations, etc.), the detection electrode 102 can still output detection information stably, effectively preventing misjudgments caused by environmental factors, shaking and rotation of the aerosol generated product 200, etc., and improving the user experience.

[0064] Please see Figure 4 In some embodiments, the detection electrode 102 includes one or more, and step 012: based on the detection information, detecting whether the aerosol generating article 200 has been pulled out includes:

[0065] Step 0121: Determine whether the difference between the detection information of each detection electrode 102 and the corresponding preset pull-out threshold is greater than the preset difference threshold and continues for a preset duration;

[0066] Step 0122: If yes, then confirm that the aerosol-generating product 200 has been removed.

[0067] The preset pull-out thresholds corresponding to each detection electrode 102 can be the same or different.

[0068] The preset pull-out threshold can be adapted to the aerosol generating device 100, aerosol generating product 200, etc.

[0069] Optionally, the preset pull-out thresholds corresponding to each detection electrode 102 are determined based on the detection information collected by each detection electrode 102 when the aerosol generating product 200 is not inserted into the accommodating cavity 104.

[0070] Each detection electrode 102 has a corresponding preset removal threshold. When the aerosol generating product 200 is not inserted into the receiving cavity 104, the detection information collected by each detection electrode 102 can be determined as the initial information. In each of the following situations—when the aerosol generating product 200 is inserted into the receiving cavity 104, when it is in the receiving cavity 104, and when it is removed from the receiving cavity 104—each detection electrode 102 can detect different changes in detection information. Therefore, by comparing the detection information collected by the detection electrode 102 with the initial information, a preset removal threshold that can be used to determine whether the aerosol generating product 200 has been removed can be determined.

[0071] Specifically, the detection electrode 102 may include one or more, for example, see [link to relevant documentation]. Figure 1 and Figure 2 Assuming the aerosol generating product 200 includes a front end 201, a medium section 202, and a support section 2031, and the detection electrode 102 includes a first detection electrode 1021 and a second detection electrode 1022, the first detection electrode 1021 can be disposed in the receiving member 101, opposite to the position of the front end 201 when the aerosol generating product 200 is inserted into the receiving cavity 104, and the second detection electrode 1022 is disposed opposite to the support section 2031. After the aerosol generating product 200 is removed, the capacitance value in the receiving cavity 104 will return to the capacitance value before the aerosol generating product 200 was inserted into the receiving cavity 104. Therefore, it can be determined whether the aerosol generating product 200 has been removed by calculating whether the difference between the capacitance value detected by the detection electrode 102 and the preset removal threshold is greater than the preset difference threshold. However, for example, when the user adjusts the position of the aerosol generating product 200 in the accommodating cavity 104, the aerosol will also be carried out of the accommodating cavity 104. At this time, the difference between the capacitance value and the preset removal threshold is also greater than the preset difference threshold. However, the user has not removed the aerosol generating product 200. Therefore, if the difference between the capacitance value and the preset removal threshold is greater than the preset difference threshold and continues for a preset time, it can be considered that the change in the detection information is caused by the aerosol generating product 200 being removed from the accommodating cavity 104, thereby determining that the aerosol generating product 200 has been removed.

[0072] Please see Figure 6In some embodiments, the detection electrode 102 includes one or more, and the plurality of detection electrodes 102 are respectively disposed at different positions of the receiving member 101. Step 012: Based on the detection information, detecting whether the aerosol generating article 200 has been pulled out includes:

[0073] Step 0123: Determine whether the difference between the detection information of each detection electrode 102 and the corresponding preset pull-out threshold is greater than the preset difference threshold and continues for a preset duration;

[0074] Step 0124: If yes, determine whether the time sequence of each detection electrode 102 reaching the corresponding preset pull-out threshold matches the position sequence of each detection electrode 102;

[0075] Step 0125: If the time sequence and position sequence match, determine that the aerosol-generated product 200 has been removed.

[0076] Specifically, during the process of the aerosol generating article 200 being removed from the accommodating cavity 104, different parts of the aerosol generating article 200 sequentially pass through each detection electrode 102, causing changes in the detection information collected by each detection electrode 102. Since the detection information collected by each detection electrode 102 is different, the changes in the detection information will also be different. Therefore, if the difference between the detection information of each detection electrode 102 and the corresponding preset removal threshold is greater than the preset difference threshold and remains greater than the preset threshold for a preset duration, the time sequence in which each detection electrode 102 reaches the corresponding preset removal threshold can be compared with the positional sequence of each detection electrode 102 to further prevent misjudgment.

[0077] For example, taking the detection electrode 102, which includes a first detection electrode 1021 and a second detection electrode 1022, as an example, assuming that when the aerosol generating product 200 is pulled out of the accommodating cavity 104, the time sequence in which each detection electrode 102 reaches its corresponding preset pull-out threshold includes the first detection electrode 1021 reaching the preset pull-out threshold first, followed by the second detection electrode 1022 reaching the preset pull-out threshold, then if the second detection electrode 1022 is detected to have reached the preset pull-out threshold first, it can be considered that the detection information of the detection electrode 102 at this time may not be a true pull-out process, but may be an error or spurious signal caused by other factors. By matching the time sequence with the position sequence, this situation that does not conform to the actual physical process can be effectively filtered out, avoiding misjudgment and greatly improving the accuracy of judgment.

[0078] For example, when the aerosol generating product 200 is basically completely atomized (i.e., the aerosol generating product 200 produces relatively little aerosol), even if suction or removal of the aerosol generating product 200 occurs, the change in detection information (capacitance change) detected by the detection electrode 102 is small. At this time, the change in detection information is mainly due to the capacitance change caused by the front end 201 and the support section 2031 themselves. Therefore, when the aerosol generating product 200 is removed, since the aerosol in the accommodating cavity 104 is basically carried out with the aerosol generating product 200, the residual aerosol in the accommodating cavity 104 is small. At this time, the detection information collected by the detection electrode 102 returns to the detection information (capacitance value) before the aerosol generating product 200 was inserted into the accommodating cavity 104. Therefore, by comparing the difference between the detection information of each detection electrode 102 and the corresponding preset removal threshold with the preset difference, and by also comparing the time sequence and position sequence of the changes of each detection electrode 102, the accuracy of detection is further improved. Figure 7 Assuming the change curve of the detection information of the first detection electrode is c2 and the change curve of the detection information of the second detection electrode is c1, by comparing the difference between the detection information of the first and second detection electrodes and the corresponding preset pull-out thresholds (l2 and l1) with the preset difference, and by comparing the time sequence and position sequence of the changes of each detection electrode 102, the accuracy of detection is further improved.

[0079] Please see Figure 8 In some embodiments, step 012: detecting whether the aerosol generating article 200 has been pulled out based on detection information, further includes:

[0080] Step 0126: Check if any sudden changes have occurred in the detection information;

[0081] Step 0127: If yes, then obtain the aspiration detection results within a preset time period that includes the moment when the detection information changes abruptly;

[0082] Step 0128: If the suction test result shows that a suction action was detected, then it is determined that the aerosol generating product 200 has not been pulled out;

[0083] Step 0129: If the suction detection result is that no suction action is detected, proceed to the step of determining whether the detection information of each detection electrode 102 is greater than the corresponding preset pull-out threshold and continues for a preset duration.

[0084] Among them, mutation can be an abnormal fluctuation or rapid change in the detection information. For example, mutation can include at least one of the following: the rate of change of the detection information is greater than the rate of aerosol accumulation when the aerosol generating product 200 generates aerosols; the change in the detection information (capacitance difference) is greater than a preset change; and the direction of change of the detection information is opposite to the direction of change when the aerosol accumulates.

[0085] The suction detection results can be used to determine whether the user has performed a suction action (removing aerosols).

[0086] The preset time period can be, for example, 3 seconds, 4 seconds, 5 seconds, 6 seconds, etc.

[0087] Specifically, during the heating process of the aerosol generating product 200, if the aerosol generating product 200 is not completely atomized and a large amount of aerosol remains in the accommodating cavity 104, and a sudden change in the detection information is detected at this time, the controller 103 can acquire the suction detection data within a preset time period starting from the time of the sudden change to determine whether a suction action has occurred. If a suction action has occurred, it can be assumed that the sudden change in the detection information is caused by the user suctioning the aerosol generating product 200. If no suction action has occurred, it can be assumed that the sudden change in the detection information may be caused by the aerosol generating product 200 being pulled out, requiring a step to determine whether the detection information of each detection electrode 102 is greater than the corresponding preset pull-out threshold and continues for a preset duration, in order to perform further pull-out detection and avoid misjudgment. For example, please refer to... Figure 7 and Figure 9 Assuming the detection information curve corresponding to the first detection electrode 1021 is c2 and the detection information curve corresponding to the second detection electrode 1022 is c1, and assuming the event of a sudden change in the first detection electrode 1021 is e1 and the event of a sudden change in the second detection electrode 1022 is e2, if a sudden change is detected but no suction action is detected, it can be determined that the aerosol-generated product has not been pulled out.

[0088] Please see Figure 10 In some embodiments, step 012: based on detection information, detecting whether the aerosol generating article 200 has been pulled out includes:

[0089] Step 0126: Check if any sudden changes have occurred in the detection information;

[0090] Step 0127: If yes, then obtain the aspiration detection results within a preset time period that includes the moment when the detection information changes abruptly;

[0091] Step 0128: If the suction test result shows that a suction action was detected, then it is determined that the aerosol generating product 200 has not been pulled out;

[0092] Step 0131: If the suction test result shows that no suction action was detected, then it is determined that the aerosol generating product 200 has been removed.

[0093] Specifically, since the changes in detection information during the heating of aerosol generation product 200 by aerosol generation device 100 are usually caused by aerosol generation product 200 being inserted into accommodating cavity 104, suction action, and aerosol generation product 200 being pulled out of accommodating cavity 104, if the detection information changes abruptly and no suction action is detected, it can also be considered that aerosol generation product 200 has been pulled out if no suction action occurs.

[0094] Please see Figure 11 In some embodiments, the controller 103 is also used for:

[0095] Step 013: Detect whether the trend of change in the detection information meets the preset trend;

[0096] Step 014: If yes, then confirm that a suction action has been detected;

[0097] Step 015: If not, then it is determined that no suction action was detected.

[0098] Optionally, the aerosol generating device 100 further includes a suction detection element for performing suction detection to obtain suction detection results.

[0099] The suction detection element can also be a detection electrode 102 (capacitance sensor), a temperature sensor, etc. For example, if the suction detection element includes a capacitance sensor, the preset trend can include the trend of the detected capacitance information change, which can be an increase followed by a decrease (when suction occurs, the aerosol is first carried away from the accommodating cavity 104, and the trend of the capacitance information change is an increase; after suction, the aerosol accumulates again, and the trend of the capacitance information change is a decrease).

[0100] Specifically, by monitoring whether the changing trend of the monitoring information meets the preset trend, for example, if the changing trend of the monitoring information meets the preset trend, it indicates that an airflow change has occurred in the accommodating cavity 104, that is, it can be considered that the user has performed suction.

[0101] Please see Figure 12To facilitate better implementation of the aerosol generating apparatus of this application, this application also provides an insertion detection device 300. The insertion detection device 300 can be used in the aerosol generating apparatus 100, which includes a receiving member 101, a detection electrode 102, and a controller 103. The receiving member 101 has a receiving cavity 104; the receiving cavity 104 is used to accommodate the aerosol generating product 200 inserted into the insertion detection device 400. The insertion detection device 400 includes an acquisition module 401 and a detection module 402. The acquisition module 401 is used to acquire multiple detection information collected by the detection electrode, which is collected by the detection electrode after the aerosol generating product is inserted into the receiving cavity. The detection module 402 is used to detect whether the aerosol generating product has been removed from the receiving cavity based on the detection information.
