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] 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 or not by comparing the sensor signal with the 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 the difference between the sensor signals in the inserted and non-inserted states is small, the sensor signals are prone to fluctuations, leading to misjudgments or repeated fluctuations in judgment. Summary of the Invention

[0004] This application provides an aerosol generating device, an aerosol generating system, and an insertion detection method, which can avoid misjudgment and ensure detection accuracy.

[0005] One embodiment of this application provides an aerosol generating apparatus, comprising a accommodating element, a detection element, and a controller. 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 element, wherein the multiple detection information are collected by the detection element when different parts of the aerosol-generated product pass through the detection element during the insertion of the aerosol-generated product into the accommodating cavity; and detect whether the aerosol-generated product is inserted into the accommodating cavity based on the changing trend of the multiple detection information.

[0006] In some embodiments, detecting whether the aerosol-generating article is inserted into the receiving cavity based on the changing trends of the multiple detection information includes: determining whether the changing trends of the multiple detection information meet a preset trend; if so, determining that the aerosol-generating article has been inserted.

[0007] In some implementations, the preset trend includes a fluctuation trend. If the fluctuation change of multiple detection information is greater than a preset fluctuation threshold and / or the slope is greater than a preset slope, the change trend of the multiple detection information is determined to satisfy the fluctuation trend.

[0008] In some embodiments, the detection element includes a detection capacitor, the detection information is the voltage of the detection capacitor, at least two locations in the aerosol generating article have different dielectric constants, and the preset trend is determined based on the position of the detection element, the dielectric constants of each location in the aerosol generating article, and the insertion order; or, the detection element includes a light sensor, the light sensor includes a light emitter and a light receiver, at least two locations in the aerosol generating article have different surface reflectivities, the detection information is light intensity, and the preset trend is determined based on the position of the detection element, the surface reflectivities of each location in the aerosol generating article, and the insertion order; or, the detection element includes a magnetic sensor, at least two locations in the aerosol generating article have different magnetic susceptibility, the detection information is magnetic field strength, and the preset trend is determined based on the position of the detection element, the magnetic susceptibility of each location in the aerosol generating article, and the insertion order.

[0009] In some embodiments, the detection element includes a first detection element, and determining whether the changing trends of the plurality of detection information meet a preset trend includes: determining whether the changing trends of the plurality of detection information meet a first fluctuation trend, wherein the first fluctuation trend is either decreasing first and then increasing or decreasing and maintaining a preset duration.

[0010] In some embodiments, the detection element includes a second detection element, and determining whether the changing trend of the plurality of detection information satisfies a preset trend includes: determining whether the changing trend of the plurality of detection information satisfies a second fluctuation trend, wherein the second fluctuation trend is a decrease and maintenance for a preset duration.

[0011] In some embodiments, the second detection element is positioned near the bottom wall of the accommodating cavity.

[0012] In some embodiments, the detection element includes a first detection element and a second detection element, which are respectively disposed at different positions in the accommodating cavity. Determining whether the changing trend of the plurality of detection information meets a preset trend includes: determining whether the changing trend of the detection information collected by the plurality of first detection elements meets a first fluctuation trend; and / or whether the changing trend of the detection information collected by the plurality of second detection elements meets a second fluctuation trend; wherein the first fluctuation trend is first decreasing and then increasing, and the second fluctuation trend is decreasing.

[0013] In some embodiments, the detection element further includes a third detection element. The first, second, and third detection elements are respectively disposed at different positions in the accommodating cavity. Determining whether the changing trends of the plurality of detection information meet a preset trend includes: determining whether the changing trends of the detection information collected by the plurality of first detection elements meet a first fluctuation trend; and / or whether the changing trends of the detection information collected by the plurality of second detection elements meet a second fluctuation trend; and / or whether the changing trends of the detection information collected by the plurality of third detection elements meet a third fluctuation trend; wherein the first fluctuation trend is first decreasing and then increasing, the second fluctuation trend is decreasing, and the third fluctuation trend is decreasing.

[0014] This application proposes an aerosol generation system, comprising: an aerosol generation article; and an aerosol generation device according to any of the above embodiments, wherein the accommodating cavity of the aerosol generation device is used to accommodate the aerosol generation article.

[0015] This application also proposes an insertion detection method for an aerosol generating device, the aerosol generating device including a receiving element and a detection element, the receiving element having a receiving cavity; the receiving cavity is used to contain an aerosol generating product, the method including: acquiring multiple detection information collected by the detection element, the multiple detection information being collected by the detection element when different parts of the aerosol generating product pass through the detection element during the insertion of the aerosol generating product into the receiving cavity; and detecting whether the aerosol generating product is inserted into the receiving cavity based on the changing trend of the multiple detection information.

[0016] 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.

[0017] The aerosol generating device, aerosol generating system, and insertion detection method of this application acquire multiple detection information collected by a detection element. These multiple detection information are collected by the detection element when different parts of the aerosol generating product pass through the detection element during the insertion of the aerosol generating product into the receiving cavity. Based on the changing trend of the multiple detection information, the system detects whether the aerosol generating product has been inserted into the receiving cavity. The judgment on whether the aerosol generating product has been inserted into the receiving cavity is based on the changing trend of the multiple detection information and does not rely on a single detection information threshold. Even if the aerosol generating device changes its usage scenario or other foreign objects are inserted into the receiving cavity (e.g., cleaning tools), the accuracy and reliability of the detection will not be affected.

[0018] For example, when a cleaning tool is inserted into the receiving cavity, if the detection information of the detection component for the cleaning tool is greater than the detection information threshold, a false identification of the insertion of the aerosol-generating product will occur. However, this application uses the analysis of the changing trends of multiple detection information to determine whether the aerosol-generating product has been inserted. Even if the detection information is greater than the detection information threshold, it will not be considered that the aerosol-generating product has been inserted into the receiving cavity. This can avoid the problems of misjudgment and repeated fluctuations in detection results caused by a single threshold, and further improve the reliability, accuracy and applicability of the detection.

[0019] Furthermore, by analyzing the changing trends of multiple detection information, it is also possible to reversely determine whether the aerosol generating product is correctly inserted or inserted in place, thus avoiding problems such as incorrect placement of the aerosol generating product or malfunction of the aerosol generating device.

Detailed Implementation

[0036] 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.

[0037] To facilitate understanding of this application, the following explanations are provided for the terms and background information used in this application:

[0038] 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 or not by comparing the sensor signal with the signal threshold. For example, if the sensor signal is greater than the signal threshold, it is determined that the aerosol product has been inserted.

[0039] However, when the difference between the sensor signal in the inserted and non-inserted states is small, or when the sensor signal is easily affected by external environmental factors (such as temperature changes, humidity fluctuations, etc.), the sensor signal is prone to fluctuation, leading to misjudgment or repeated fluctuations in judgment. Since a fixed threshold cannot adapt to all application scenarios, the accuracy of detection cannot be guaranteed when HNB devices are used in different application scenarios, affecting the user experience.

[0040] Furthermore, when objects that cause similar changes in sensor characteristics are inserted (such as cleaning tools), they are easily mistaken for aerosol products, leading to misidentification.

[0041] To address the aforementioned technical problems, this application provides an aerosol generating apparatus.

[0042] The application scenarios of the technical solution in this application will be introduced below. Please refer to [link / reference]. Figure 1 This application provides an aerosol generation system 1000, which includes an aerosol generation device 100 and an aerosol generation article 200. The aerosol generation device 100 includes a receiving member 101 and a detection member 102. The receiving member 101 has a receiving cavity 103 for receiving at least a portion of the aerosol generation article 200. The aerosol generation device 100 also includes a controller 104, which can be used to perform an insertion detection method.

[0043] Optionally, the aerosol generating article 200 includes a front end 201, a medium segment 202 and a functional segment 203, the medium segment 202 is located between the front end 201 and the functional segment 203, and the medium segment 202 includes an aerosol generating matrix; the detection element 102 is disposed in the area opposite to the accommodating element 101 and the medium segment 202.

[0044] Specifically, functional segment 203 may include at least one of cooling segment 2031 and filtration segment 2032. For example, functional segment 203 may include filtration segment 2032 and cooling segment 2031; for another example, functional segment 203 may include filtration segment 2032; for yet another example, functional segment 203 may include cooling segment 2031, and this application does not limit this.

[0045] Optionally, the controller 104 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.

[0046] Optionally, the aerosol generating device 100 includes a second detection element 105, which is disposed near the bottom wall of the accommodating cavity 103.

[0047] Optionally, the aerosol generating device 100 includes a third detection element 106, which is positioned opposite to the connection between the front end 201 and the medium section 202 after the aerosol generating article 200 is inserted into place; and / or, positioned above the second detection element 105, etc.

[0048] The aerosol generating apparatus 100 of this application will now be described in detail:

[0049] This application provides an aerosol generating apparatus 100. Please refer to [link to relevant documentation]. Figure 1 and Figure 2 The aerosol generating apparatus 100 includes a receiving member 101 and a detection member 102. The receiving member 101 has a receiving cavity 103 for receiving at least a portion of the aerosol generating article 200. The aerosol generating apparatus 100 also includes a controller 104, which can be used to execute an insertion detection method, wherein the insertion detection method includes:

[0050] Step 011: Acquire multiple detection information collected by the detection component 102. The multiple detection information is collected by the detection component 102 when different parts of the aerosol generating product 200 pass through the detection component 102 during the process of inserting the aerosol generating product 200 into the accommodating cavity 103.

[0051] Step 012: Based on the changing trends of multiple detection information, detect whether the aerosol-generated product 200 is inserted into the accommodating cavity 103.

[0052] The aerosol generating device 100 can be a device or equipment capable of processing (such as heating) the aerosol generating product 200 to obtain an aerosol generating matrix.

[0053] The detection element 102 can be a detection device capable of collecting capacitance information (such as capacitance value), voltage information (such as voltage value and voltage change), current information (such as current value and current change), temperature information (such as temperature value and temperature change), and magnetic information (such as magnetic field strength and direction) (such as a Hall effect sensor). The detection information can include information of different magnitudes (e.g., capacitance value, capacitance information, photoelectric information, photoelectric value, etc.) corresponding to the detection element 102 detecting different positions of the aerosol generating product 200.

[0054] For example, taking the detection element 102 including a capacitance detection device (such as a capacitance sensor) as an example, during the insertion of the aerosol generating product 200 into the receiving cavity 103, different parts of the aerosol generating product 200 pass through the detection element 102, and the dielectric constants of the different parts are different, resulting in different detection information (i.e., capacitance information) collected by the detection element 102. At this time, the detection information includes multiple different capacitance values. As another example, taking the detection element 102 including a photoelectric sensor for collecting photoelectric information as an example, during the insertion of the aerosol generating product 200 into the receiving cavity 103, different parts of the aerosol generating product 200 pass through the detection element 102, and the light intensity reflected from the different parts is different, resulting in different detection information (i.e., light intensity values) collected by the detection element 102. At this time, the detection information includes multiple different light intensity values.

[0055] For ease of description, this application will use the example of a detection device 102 including capacitance detection device and detection information including capacitance information. The capacitance information can be represented as a voltage value, and the trend of capacitance information change can be represented as the trend of voltage value change. The capacitance detection device outputs different voltages for materials with different dielectric constants; the higher the dielectric constant of the detected material, the lower the voltage output by the capacitance detection device.

[0056] The trend of change can include the direction of change of the detection information collected by the detection component 102 within a preset time period.

[0057] Optionally, the detection element 102 can be set at a position where different detection information can be collected when the aerosol generating article 200 is inserted into the receiving cavity 103. For example, it can be set at a position near the top or bottom wall of the receiving cavity 103.

[0058] Optionally, the detection element 102 may include one or more, and multiple detection elements 102 may be disposed at different positions in the receiving cavity 103.

[0059] Optionally, the aerosol generating article 200 includes a front end 201, a medium segment 202 and a functional segment 203, the medium segment 202 is located between the front end 201 and the functional segment 203, and the medium segment 202 includes an aerosol generating matrix; the detection element 102 is disposed in the area opposite to the accommodating element 101 and the medium segment 202.

[0060] The medium section 202 may contain a matrix material capable of generating aerosols, such as tobacco or plant extracts (e.g., mugwort). When the matrix material is heated by a heat source or subjected to physical atomization, it can release aerosols for user use.

[0061] The front-end component 201 can be used to prevent leakage of aerosols generated by the aerosol generating product 200.

[0062] Among them, functional segment 203 can come into contact with the user and can filter out impurities in aerosols, improving the user experience.

[0063] For example, please see Figure 8 Taking functional section 203, which includes a filtration section 2032 and a cooling section 2031, as an example, the aerosol-generating product 200 in the medium section 202, when heated, can release high-temperature aerosols. These aerosols pass through the cooling section 2031 and the filtration section 2032 before coming into contact with the user (e.g., entering the user's mouth for inhalation). It is understandable that direct contact between high-temperature aerosols and the user could easily affect user safety and experience. Therefore, by setting up the cooling section 2031, the temperature of the aerosol is reduced, preventing irritation and harm to the user and ensuring a better user experience. The aerosols generated from the matrix material may contain impurities such as tiny particles. By setting up a filter, the user experience can be further improved, and the filter can also help regulate airflow, allowing the aerosol to enter the user's mouth more evenly.

[0064] Optionally, the aerosol generating article 200 may include a front end 201, a medium section 202, and a functional section 203, for example, see [link to relevant documentation]. Figure 1 The aerosol generating product 200200 includes a front end component 201 at one end and a functional segment 203 at the other end. A medium segment 202 is provided between the functional segment 203 and the front end component 201.

[0065] Optionally, the aerosol generating article 200 may include a functional segment 203 and a media segment 202. For example, see [link to relevant documentation]. Figure 3 The aerosol generating product 200200 includes a medium section 202 and a functional section 203.

[0066] Specifically, the aerosol generating device 100 has a receiving cavity 103 within its receiving member 101. The receiving cavity 103 can accommodate the aerosol generating product 200, and the detection element 102 can output corresponding detection information based on the characteristics of the material being detected (e.g., dielectric constant). During the insertion of the aerosol generating product 200 into the receiving cavity 103, different parts of the aerosol generating product 200 pass through the detection element 102 sequentially. Since the material characteristics of different parts of the aerosol generating product 200 are different (e.g., different light reflectivity, different dielectric constant), the detection element 102 can collect multiple detection information accordingly. Based on the changing trend of the multiple detection information over time, it is determined whether the aerosol generating product 200 is inserted into the receiving cavity 103. For example, if the changing trend of the multiple detection information matches a preset trend (e.g., a change from large to small), it is determined that the aerosol generating product 200 is inserted into the receiving cavity 103.

[0067] Thus, the aerosol generating device 100 includes a receiving element 101, a detection element 102, and a controller 104. The receiving element 101 has a receiving cavity 103; the receiving cavity 103 is used to accommodate the aerosol generating product 200. The detection element 102 can be disposed on the receiving element 101. The detection element 102 can collect and monitor multiple detection information in real time during the process of the aerosol generating product 200 being inserted into the receiving cavity 103. By acquiring the multiple detection information collected by the detection element 102, the multiple detection information indicates the aerosol generation process during the insertion of the aerosol generating product 200 into the receiving cavity 103. The aerosol-generated product 200 is detected by the detection element 102 as different parts of the product pass through it. Based on the changing trends of multiple detection information, the system detects whether the aerosol-generated product 200 has been inserted into the receiving cavity 103. The determination of whether the aerosol-generated product 200 has been inserted into the receiving cavity 103 is based on the changing trends of multiple detection information and does not rely on a single detection information threshold. Even if the aerosol generating device 100 changes its usage scenario or other foreign objects are inserted into the receiving cavity 103 (e.g., cleaning tools), the accuracy and reliability of the detection will not be affected.

[0068] For example, when a cleaning tool is inserted into the receiving cavity 103, if the detection information of the detection element 102 on the cleaning tool is greater than the detection information threshold, a false identification of the insertion of the aerosol generating article 200 will occur. However, this application uses the analysis of the changing trends of multiple detection information to determine whether the aerosol generating article 200 has been inserted. Even if the detection information is greater than the detection information threshold, it will not be considered that the aerosol generating article 200 has been inserted into the receiving cavity 103. This can avoid the problems of misjudgment and repeated fluctuations in detection results caused by a single threshold, and further improve the reliability, accuracy and applicability of the detection.

[0069] Furthermore, by analyzing the changing trends of multiple detection information, it is also possible to reversely determine whether the aerosol generating product 200 is correctly inserted or inserted in place, thus avoiding problems such as the aerosol generating product 200 not being placed correctly or the aerosol generating device 100 malfunctioning.

[0070] Please see Figure 4 In some embodiments, step 012: detecting whether the aerosol-generating article 200 is inserted into the receiving cavity 103 based on the changing trends of multiple detection information includes:

[0071] Step 0121: Determine whether the changing trends of multiple detection information meet the preset trends;

[0072] Step 0122: If yes, then confirm that the aerosol generating article 200 has been inserted.

[0073] Optionally, the preset trend includes a fluctuation trend. If the fluctuation change of multiple detection information is greater than a preset fluctuation threshold and / or the slope is greater than a preset slope, the change trend of multiple detection information is determined to satisfy the fluctuation trend.

[0074] The fluctuation amount can include the difference between the maximum and minimum values ​​among multiple detection information. The preset fluctuation threshold can be determined according to the characteristics of the aerosol generating product 200. When the fluctuation amount is greater than the preset fluctuation threshold, it can be considered that different parts of the aerosol generating product 200 have passed through the detection element 102 (so that the fluctuation amount of the detection information collected by the detection element 102 can meet the requirements), that is, the aerosol generating product 200 is inserted into the accommodating cavity 103.

[0075] The slope can be calculated based on the difference between the maximum and minimum values ​​among multiple detection information, and the time difference between the acquisition of the maximum and minimum values; the slope can also be the slope of the fitted straight line of multiple detection information (e.g., the least squares fitted straight line). The preset slope can be determined based on the characteristics of the aerosol generating product 200. For ease of calculation, the slope can be taken as an absolute value. By comparing the absolute value of the slope with the preset slope, if the slope is greater than the preset slope, it can be considered that different parts of the aerosol generating product 200 have passed through the detection element 102 (so that the slope of the detection information acquired by the detection element 102 meets the requirements), that is, the aerosol generating product 200 is inserted into the receiving cavity 103.

[0076] Optionally, the detection element 102 includes a detection capacitor, and the detection information is the voltage of the detection capacitor. At least two parts of the aerosol generating article 200 have different dielectric constants, and the preset trend is determined based on the position of the detection element 102, the dielectric constant of each part of the aerosol generating article 200, and the insertion order.

[0077] Alternatively, the detection element 102 includes a light sensor, which includes a light emitter and a light receiver. At least two parts of the aerosol generating article 200 have different surface reflectivities, and the detection information is light intensity. The preset trend is determined based on the position of the detection element 102, the surface reflectivities of each part of the aerosol generating article 200, and the insertion order.

[0078] Alternatively, the detection element 102 may include a magnetic sensor, where at least two parts of the aerosol generating article 200 have different magnetic susceptibility, and the detection information is the magnetic field strength. The preset trend is determined based on the position of the detection element 102, the magnetic susceptibility of each part of the aerosol generating article 200, and the insertion order.

[0079] In this case, at least two parts of the aerosol generating article 200 have different dielectric constants. For example, taking an aerosol generating article 200 that includes a front end 201, a dielectric segment 202, and a functional segment 203, at least two of these parts have different dielectric constants. As another example, taking an aerosol generating article 200 that includes a dielectric segment 202 and a functional segment 203, the dielectric constants of the dielectric segment 202 and the functional segment 203 are different.

[0080] The changing trends of the detection information during the insertion of the aerosol generating product 200 into the receiving cavity 103 vary depending on the placement of the detection element 102. For example, when the detection element 102 is located near the top of the receiving cavity 103 and within the receiving element 101, the changing trend collected by the detection element 102 during the insertion of the aerosol generating product 200 includes the changing trend based on the detection information from the bottom to the top of the aerosol generating product 200. When the detection element 102 is located near the bottom wall of the receiving cavity 103, the changing trend collected by the detection element 102 during the insertion of the aerosol generating product 200 includes the changing trend based on the detection information from air to the bottom of the aerosol generating product 200. Therefore, the preset trend is determined based on the position of the detection element 102, the dielectric constant of various parts of the aerosol generating product 200, and the insertion order.

[0081] The optical sensor includes a light emitter and a light receiver. The light emitted by the light emitter (e.g., infrared light) is reflected back to the optical sensor when it encounters the aerosol-generating article 200, and is received by the light receiver. The light intensity is obtained by analyzing the light received by the light receiver. The intensity of the light reflected back to the light receiver varies depending on the surface reflectivity. Similarly, a preset trend can be determined based on the position of the detection element 102, the surface reflectivity of various parts of the aerosol-generating article 200, and the insertion order.

[0082] The detection element 102 includes a magnetic sensor (e.g., a Hall sensor, a magnetoresistive sensor, a magnetometer, etc.). The magnetic sensor can detect the magnetic susceptibility of an object and output corresponding magnetic field strength information based on the magnitude of the magnetic susceptibility. Similarly, based on the position of the detection element 102, the magnetic susceptibility of various parts of the aerosol-generating product 200, and the insertion order, a preset trend can be determined.

[0083] Specifically, after acquiring multiple detection information, it can be determined that the aerosol generating product 200 has been inserted by analyzing whether the changing trend of the multiple detection information along the time sequence matches the preset trend (e.g., whether they are the same).

[0084] For example, please see Figure 5 Taking the detection element 102, which includes a detection capacitor, as an example, the detection capacitor is located on the top of the receiving element 101 and near the receiving cavity 103. The preset trend includes a fluctuation trend. The explanation focuses on determining that the change trend of multiple detection information satisfies the fluctuation trend when the fluctuation change of multiple detection information exceeds a preset fluctuation threshold. Assume that the aerosol generating product 200 includes three parts: a front-end part 201, a dielectric section 202, and a functional section 203. The dielectric constants of the three parts are: dielectric section 202 (assuming a higher voltage) < front-end part 201 (assuming a higher voltage) < functional section 203 (assuming a lower voltage). The insertion order of the aerosol generating product 200 into the receiving cavity 103 is: front-end part 201, dielectric section 202, and functional section 203. During the insertion of the aerosol generating product 200 into the accommodating cavity 103, the detection capacitor sequentially collects the capacitance information of the front end 201, the dielectric section 202, and the functional section 203. The voltage change at this time is shown in the figure. The fluctuation amount is determined based on the difference between the voltage values. The fluctuation amount is then compared with a preset threshold. If the fluctuation amount is greater than the preset threshold, it can be considered that the fluctuation amount is calculated based on the dielectric section 202 and the functional section 203, and it is determined that the aerosol generating product 200 has been inserted.

[0085] For example, let's take a detection element 102 that includes a light sensor, which includes a light receiver and a light emitter. The light sensor is located on the bottom wall of the receiving element 101 near the receiving cavity 103. The preset trend includes a fluctuation trend. The explanation is based on the assumption that the changing trend of multiple detection information satisfies the fluctuation trend when the slope (or absolute value of the slope) of multiple detection information is greater than the preset slope. Assume that the aerosol generating product 200 includes three parts: a front end 201, a medium section 202, and a functional section 203. The surface reflectivity of the three parts is as follows: front end 201 (assuming a relatively high light intensity) > medium section 202 (assuming a high light intensity) > functional section 203 (assuming a low light intensity) > air. The insertion order of the aerosol generating product 200 into the receiving cavity 103 is: front end 201, medium section 202, and functional section 203. During the insertion of the aerosol generating article 200 into the receiving cavity 103, the light emitter continuously emits light (e.g., infrared light), and the light receiver sequentially receives the light reflected from the air and the front end 201, and outputs multiple light intensity data accordingly. Based on the difference between the maximum and minimum values ​​of the multiple light intensity data and the acquisition time value, the slope of multiple detection information is calculated. If the slope is greater than the preset slope, it can be considered that the maximum and minimum values ​​correspond to the light intensity acquired when the front end 201 passes the light sensor and the light intensity acquired by the light sensor before the aerosol generating article is inserted, thereby determining that the aerosol generating article 200 has been inserted.

[0086] For example, let's take a detection element 102 that includes a magnetic sensor, which is located on the top of the receiving element 101 near the receiving cavity 103. The preset trend includes a fluctuation trend. The explanation is based on the scenario where the fluctuation changes of multiple detection information exceed a preset fluctuation threshold, and the trend of these multiple detection information is determined to satisfy the fluctuation trend. Assume the aerosol generating product 200 includes three parts: a front-end part 201, a medium section 202, and a functional section 203. The magnetic susceptibility of these three parts is: medium section 202 (assuming a higher magnetic field strength) > front-end part 201 (assuming a higher magnetic field strength) > functional section 203 (assuming a lower magnetic field strength). The insertion order of the aerosol generating product 200 into the receiving cavity 103 is: front-end part 201, medium section 202, and functional section 203. During the insertion of the aerosol-generating product 200 into the accommodating cavity 103, the magnetic sensor sequentially collects the magnetic field strength of the front end 201, the medium section 202, and the functional section 203. Based on the difference between the maximum and minimum values ​​of the multiple magnetic field strengths, the fluctuation amount is determined. Then, the fluctuation amount is compared with a preset threshold. If the fluctuation amount is greater than the preset threshold, it can be considered that the fluctuation amount is calculated based on the medium section 202 and the functional section 203, thereby determining that the aerosol-generating product 200 has been inserted.

[0087] Thus, by comparing the changing trends of multiple detection information with the preset trends, it is possible to determine whether the aerosol generating product 200 has been inserted, which can improve the accuracy of detection and avoid misidentification.

[0088] Please see Figure 5 In some embodiments, the detection element 102 includes a first detection element 102. Step 0121: Determining whether the changing trend of multiple detection information meets a preset trend includes:

[0089] Step 01211: Determine whether the changing trends of multiple detection information meet the first fluctuation trend, which is either decreasing first and then increasing or decreasing and maintaining a preset duration.

[0090] Specifically, the detection element 102 includes a first detection element 102, please refer to [link / reference]. Figure 6Taking the first detection element 102 including a detection capacitor as an example, the first detection element 102 can be set at the top of the accommodating element 101 and close to the accommodating cavity 103. When the aerosol generating product 200 includes a front end 201, a dielectric section 202 and a functional section 203, during the process of inserting the aerosol generating product 200 into the accommodating cavity 103, the first detection element 102 sequentially collects multiple capacitance data of the front end 201, the dielectric section 202 and the functional section 203. The fluctuation trend of the multiple capacitance data is that it first decreases (from the front end 201 to the dielectric section 202) and then increases (from the dielectric section 202 to the functional section 203). For example, continuing the previous example, taking the case where the first detection element 102 can be set at a position near the bottom wall of the accommodating member 101 close to the accommodating cavity 103, when the aerosol generating product 200 includes a dielectric section 202 and a functional section 203, during the process of the aerosol generating product 200 being inserted into the accommodating cavity 103, the first detection element 102 sequentially collects multiple capacitance data of the air and the front end member 201 (assuming that the dielectric constant of the front end member 201 is greater than that of the air). After the aerosol generating product 200 is inserted into the accommodating cavity 103, it will stay in the accommodating cavity 103. Therefore, the first fluctuation trend of the capacitance data collected by the first detection element 102 is to decrease and maintain a preset duration.

[0091] Please see Figure 7 In some embodiments, the detection element 102 includes a second detection element 105. Step 0121: Determining whether the changing trend of multiple detection information meets a preset trend includes:

[0092] Step 01212: Determine whether the changing trends of multiple detection information meet the second fluctuation trend, which is to decrease and maintain a preset duration.

[0093] The second detection element 105 is located near the bottom wall of the accommodating cavity 103.

[0094] Specifically, please refer to Figure 1 and Figure 8 When the second detection element 105 is positioned near the bottom wall of the accommodating cavity 103, if the changing trend of multiple detection information collected by the second detection element 105 matches (is the same as) the second fluctuation trend (decreases and remains for a preset duration), then it is determined that the changing trend of multiple detection information satisfies the preset trend.

[0095] Please see Figure 9 In some embodiments, the detection element 102 includes a first detection element 102 and a second detection element 105, which are respectively disposed at different positions in the accommodating cavity 103. Step 0121: Determining whether the changing trend of multiple detection information meets a preset trend includes:

[0096] Step 01213: Determine whether the changing trend of the detection information collected by the multiple first detection elements 102 satisfies the first fluctuation trend; and / or whether the changing trend of the detection information collected by the multiple second detection elements 105 satisfies the second fluctuation trend;

[0097] The first fluctuation trend is a decrease followed by an increase, while the second fluctuation trend is a decrease.

[0098] The first detection element 102 is located near the top of the accommodating cavity 103, and the second detection element 105 is located near the bottom wall of the accommodating cavity 103.

[0099] The first detection element 102 and the second detection element 105 can each be at least one of a detection capacitor, an optical sensor, and a magnetic sensor. The first detection element 102 and the second detection element 105 can each include one or more; for ease of description, this example will be given where both the first detection element 102 and the second detection element 105 are a single detection capacitor.

[0100] Specifically, during the insertion of the aerosol-generating article 200 into the accommodating cavity 103, the first detection element 102, located near the top of the accommodating cavity 103, sequentially collects multiple capacitance data points from the front-end component 201, the dielectric section 202, and the functional section 203. The fluctuation trend of these capacitance data points is characterized by a first decrease (from the front-end component 201 to the dielectric section 202) followed by an increase (from the dielectric section 202 to the functional section 203). The second detection element 105, located near the bottom wall of the accommodating cavity 103, sequentially collects multiple capacitance data points from the air and the front-end component 201. The fluctuation trend of these capacitance data points is characterized by a second decreasing trend.

[0101] Please see Figure 10 In some embodiments, the detection element 102 further includes a third detection element 106. The first detection element 102, the second detection element 105, and the third detection element 106 are respectively disposed at different positions in the accommodating cavity 103. Step 0121: Determine whether the changing trend of multiple detection information meets a preset trend, including:

[0102] Step 01214: Determine whether the changing trend of the detection information collected by multiple first detection elements 102 meets the first fluctuation trend; and / or whether the changing trend of the detection information collected by multiple second detection elements 105 meets the second fluctuation trend; and / or whether the changing trend of the detection information collected by multiple third detection elements 106 meets the third fluctuation trend.

[0103] The first fluctuation trend is a decrease followed by an increase, the second fluctuation trend is a decrease, and the third fluctuation trend is a decrease.

[0104] The third detection element 106 may be positioned above the second detection element 105; and / or, located at the position opposite to the connection between the medium section 202 and the front end element 201 when the aerosol generating product 200 is inserted into the accommodating cavity 103, so as to avoid detection errors of the second detection element 105 caused by the aerosol generating product 200 not being inserted into the accommodating cavity.

[0105] Specifically, if at least one of the following conditions is met: the changing trend of the detection information collected by multiple first detection devices 102 satisfies the first fluctuation trend; the changing trend of the detection information collected by multiple second detection devices 105 satisfies the second fluctuation trend; and the changing trend of the detection information collected by multiple third detection devices 106 satisfies the third fluctuation trend, it can be considered that the aerosol generating product 200 has been inserted.

The insertion detection device 300 can be used in an aerosol generating apparatus, which includes a receiving element, a detection element, and a controller. The receiving element has a receiving cavity for accommodating the aerosol-generated product. The insertion detection device 300 includes an acquisition module 301 and a detection module 302. The acquisition module 301 is used to acquire multiple detection information collected by the detection element. These multiple detection information are collected by the detection element when different parts of the aerosol-generated product pass through the detection element during the insertion of the aerosol-generated product into the receiving cavity. The detection module 302 is used to detect whether the aerosol-generated product is inserted into the receiving cavity based on the changing trend of the multiple detection information.

[0107] In some embodiments, the detection module 302 is further used to determine whether the changing trend of multiple detection information meets a preset trend; if so, it is determined that the aerosol-generated article has been inserted.

[0108] In some implementations, the detection module 302 is further used to determine whether the changing trend of multiple detection information satisfies a first fluctuation trend, wherein the first fluctuation trend is either a decrease followed by an increase or a decrease and a retention time of a preset duration.

[0109] In some implementations, the detection module 302 is further configured to determine whether the changing trends of multiple detection information satisfy a second fluctuation trend, wherein the second fluctuation trend is to decrease and remain for a preset duration.
