Detailed Implementation
[0047] The embodiments of this application are described in detail below. Examples of these 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 this application, and should not be construed as limiting this application.
[0048] To facilitate understanding of this application, the following explanations are provided for the terms and background information used in this application:
[0049] 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.
[0050] 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.
[0051] 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.
[0052] To address the aforementioned technical problems, this application provides an aerosol generating apparatus.
[0053] The application scenario of the technical solution of this application will be introduced below. Referring to 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 execute an insertion detection method.
[0054] 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.
[0055] 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.
[0056] 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.
[0057] Optionally, the aerosol generating device 100 includes a second detection element 105, which is disposed near the bottom wall of the accommodating cavity 103.
[0058] 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.
[0059] The aerosol generating apparatus 100 of this application will now be described in detail:
[0060] This application provides an aerosol generating apparatus 100. Referring to Figures 1 and 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-generated article 200. The aerosol generating apparatus 100 also includes a controller 104, which can be used to perform:
[0061] Step 110: Acquire multiple detection information collected by the test piece. The multiple detection information is obtained by the test piece during the insertion of the aerosol generating product into the receiving cavity, and / or after the aerosol generating product is inserted into the receiving cavity.
[0062] Step 120: Based on multiple detection information, detect the presence and / or suction status of the aerosol-generated product in the accommodating cavity.
[0063] During the insertion of the aerosol-generating product into the receiving cavity, and / or after the aerosol-generating product is inserted into the receiving cavity, the detection device can collect multiple detection information. Based on the detection information, the presence status of the aerosol-generating product in the receiving cavity (including whether the aerosol-generating product is inserted into the receiving cavity, and / or whether the aerosol-generating product is removed from the receiving cavity), and / or the suction status (whether the aerosol-generating product is suctioned) can be detected.
[0064] Optionally, the controller 104 can be used to execute an insertion detection method, wherein the insertion detection method includes:
[0065] 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.
[0066] 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.
[0067] 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.
[0068] 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.
[0069] 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.
[0070] 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.
[0071] 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.
[0072] 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.
[0073] 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.
[0074] 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.
[0075] 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.
[0076] The front-end component 201 can be used to prevent leakage of aerosols generated by the aerosol generating product 200.
[0077] Among them, functional segment 203 can come into contact with the user and can filter out impurities in aerosols, improving the user experience.
[0078] For example, referring to Figure 8, taking functional segment 203, which includes a filter segment 2032 and a cooling segment 2031, as an example, the aerosol-generating article 200 in the medium segment 202, when heated, can release high-temperature aerosols. The aerosols pass through the cooling segment 2031 and the filter segment 2032 before contacting the user (e.g., entering the user's mouth for inhalation). It is understood that direct contact between high-temperature aerosols and the user could easily affect user safety and experience. Therefore, by setting the cooling segment 2031, the temperature of the aerosol is reduced, avoiding irritation and harm to the user and ensuring a better user experience. Aerosols generated from matrix materials often contain impurities such as tiny particles. By setting 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.
[0079] Optionally, the aerosol generating article 200 may include a front end 201, a medium segment 202, and a functional segment 203. For example, referring to FIG1, the aerosol generating article 200 includes a front end 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 201.
[0080] Optionally, the aerosol generating article 200 may include a functional segment 203 and a medium segment 202. For example, referring to FIG3, the aerosol generating article 200 includes a medium segment 202 and a functional segment 203.
[0081] 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.
[0082] 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.
[0083] 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.
[0084] 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.
[0085] Please refer to Figure 4. In some embodiments, step 012: Based on the changing trends of multiple detection information, detecting whether the aerosol-generating article 200 is inserted into the receiving cavity 103 includes:
[0086] Step 0121: Determine whether the changing trends of multiple detection information meet the first preset trend;
[0087] Step 0122: If yes, then confirm that the aerosol generating article 200 has been inserted.
[0088] Optionally, the first 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.
[0089] 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.
[0090] 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.
[0091] 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. The first 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.
[0092] 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 first 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.
[0093] 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 first 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.
[0094] 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.
[0095] 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 first 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.
[0096] The optical sensor includes a light emitter and a light receiver. 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 first 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.
[0097] 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 first preset trend can be determined.
[0098] Specifically, after acquiring multiple detection information, it can be determined that the aerosol generating article 200 has been inserted by analyzing whether the changing trend of the multiple detection information along the time sequence matches the first preset trend (e.g., whether they are the same).
[0099] For example, referring to Figure 5, the detection element 102 includes a detection capacitor, which is located on the top of the receiving element 101 near the receiving cavity 103. The first preset trend includes a fluctuation trend. When the fluctuation change of multiple detection information is greater than a preset fluctuation threshold, it is determined that the change trend of multiple detection information satisfies the fluctuation trend. Assume that the aerosol generating product 200 includes three parts: a front end 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 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 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.
[0100] 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 first 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 reflectance 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.
[0101] 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 first preset trend includes a fluctuation trend. The explanation is based on the assumption that the changing trends of multiple detection information satisfy the fluctuation trend when the fluctuation changes of multiple detection information exceed a preset fluctuation threshold. 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 the 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.
[0102] Thus, by comparing the changing trends of multiple detection information with the first preset trend, it is possible to determine whether the aerosol generating product 200 has been inserted, which can improve the accuracy of detection and avoid misidentification.
[0103] Referring to 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 satisfies a first preset trend includes:
[0104] 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.
[0105] Specifically, the detection element 102 includes a first detection element 102. Please refer to Figure 6. Taking the first detection element 102 as an example, which includes a detection capacitor, 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.
[0106] Referring to 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 satisfies a first preset trend includes:
[0107] 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.
[0108] The second detection element 105 is located near the bottom wall of the accommodating cavity 103.
[0109] Specifically, please refer to Figures 1 and 8. When the second detection element 105 is located 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 first preset trend.
[0110] Referring to 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 satisfies a first preset trend includes:
[0111] 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;
[0112] The first fluctuation trend is a decrease followed by an increase, while the second fluctuation trend is a decrease.
[0113] 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.
[0114] 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.
[0115] 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.
[0116] Referring to 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 satisfies a first preset trend, including:
[0117] 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.
[0118] 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.
[0119] 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.
[0120] 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.
[0121] It is understandable that in related technologies, a large amount of aerosol is generated during the heating process of aerosol products, and a large amount of aerosol is also carried away during suction. Since some sensors can also respond to changes in aerosol and output sensor signals, when the sensor changes caused by the generation and suction of aerosol meet the removal judgment conditions, false judgments are likely to occur, leading to the interruption of heating of the appliance, resulting in waste of aerosol products and affecting the user experience.
[0122] In view of this, in some embodiments, the controller 104 can also be used to perform a detection method. The detection element 102 includes a detection electrode 102. Multiple detection information is collected by the detection electrode 102 after the aerosol generating product 200 is inserted into the accommodating cavity 103. The existence status includes whether the aerosol generating product 200 has been removed from the accommodating cavity 103.
[0123] For ease of understanding, please refer to Figures 11 and 12 for further introduction and explanation of the application scenarios of the technical solution of this application. The aerosol generation system 1000 includes an aerosol generation device 100 and an aerosol generation product 200. The aerosol generation device 100 includes a receiving element 101, a detection electrode 102, and a controller 104. The receiving element 101 has a receiving cavity 103 for containing and fixing the aerosol generation product 200. The aerosol generation device 100 can heat the aerosol generation product 200 to obtain aerosol.
[0124] 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.
[0125] 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.
[0126] 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.
[0127] 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.
[0128] Optionally, the detection electrode 102 may include a detection capacitor.
[0129] 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.
[0130] 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 103, and the second detection electrode 1022 can be disposed opposite to the position of the support section 2031.
[0131] 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.
[0132] 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 103, 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.
[0133] 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.
[0134] Optionally, referring to Figure 13, the aerosol generating device 100 may include a detection module 301, a suction detection module 302, and a control module 303.
[0135] 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 103; 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 103 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.
[0136] 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 (as shown in Figure 3, the first detection module 3011 is disposed on the receiving member 101 and is located opposite to the bottom of the receiving cavity 104, and the second detection module 3012 is disposed on the receiving member 101 and is located opposite to 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 shown in Figure 3, 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.
[0137] Optionally, step 120: Based on multiple detection information, detect the presence and / or suction state of the aerosol-generating article 200, including:
[0138] Step 021: Based on the detection information, detect whether the aerosol-generated product 200 has been removed from the accommodating cavity 103.
[0139] In other words, as shown in Figure 14, the detection methods include:
[0140] Step 020: Acquire multiple detection information collected by the detection electrode. The multiple detection information is collected by the detection electrode after the aerosol-generated product is inserted into the accommodating cavity.
[0141] Step 021: Based on the detection information, detect whether the aerosol-generated product 200 has been removed from the accommodating cavity 103.
[0142] The detection electrode 102 can sense the presence of the aerosol-generating product 200 within the accommodating cavity 103 and convert it into detection information. This detection information can be, for example, capacitance, voltage, or current values.
[0143] Optionally, the detection electrode 102 can be a capacitive detection sensor, an optical detection sensor, etc.
[0144] Specifically, the aerosol generating device 100 includes a receiving element 101, a detection electrode 102, and a controller 104. The receiving element 101 has a receiving cavity 103 for accommodating the aerosol generating product 200. The aerosol generating device 100 can heat the aerosol generating product 200 placed in the receiving cavity 103, 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 103. After the aerosol generating product 200 is inserted into the receiving cavity 103, multiple detection information continuously collected by the detection electrode 102 can be transmitted to the controller 104. After acquiring multiple detection information, the controller 104 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 103.
[0145] 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 103, 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 103, 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 103, 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 103.
[0146] 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 103, 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 103. The detection information detected by the capacitance detection sensor is affected by the accumulated aerosol and the aerosol generating product 200 itself. The detection information can be reflected as an increasing capacitance value. When the aerosol generating product 200 is removed from the receiving cavity 103, 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 103.
[0147] Thus, the aerosol generating device 100 includes a receiving element 101, a detection electrode 102, and a controller 104. The receiving element 101 has a receiving cavity 103; the receiving cavity 103 is used to contain the aerosol generating product 200; the controller 104 is used to 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 receiving cavity 103, so as to monitor the state of the aerosol generating product 200 in the receiving cavity 103; based on the detection information, the aerosol is detected. Whether the generated product 200 has been removed from the receiving cavity 103 is determined, which improves the identification rate of the aerosol generated product 200 being pulled out. Because the detection electrode 102 has the characteristics of high precision and high sensitivity, it can ensure the detection accuracy of the insertion and removal of the aerosol generated product 200. 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.
[0148] Referring to Figure 15, in some embodiments, the detection electrode 102 includes one or more. Step 021: Based on the detection information, detecting whether the aerosol generating article 200 has been pulled out includes:
[0149] Step 0211: 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;
[0150] Step 0212: If yes, then confirm that the aerosol-generating product 200 has been removed.
[0151] The preset pull-out thresholds corresponding to each detection electrode 102 can be the same or different.
[0152] The preset pull-out threshold can be adapted to the aerosol generating device 100, aerosol generating product 200, etc.
[0153] 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 103.
[0154] Each detection electrode 102 has a corresponding preset removal threshold. When the aerosol generating product 200 is not inserted into the receiving cavity 103, the detection information collected by each detection electrode 102 can be determined as the initial information. In each of the following situations—insertion of the aerosol generating product 200 into the receiving cavity 103, being in the receiving cavity 103, and being removed from the receiving cavity 103—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.
[0155] Specifically, the detection electrode 102 may include one or more. For example, referring to Figures 1 and 2, assuming the aerosol generating article 200 includes a front end 201, a medium section 202, and a support section 2031, the detection electrode 102 includes a first detection electrode 1021 and a second detection electrode 1022. The first detection electrode 1021 may be disposed in the receiving member 101, opposite to the position of the front end 201 when the aerosol generating article 200 is inserted into the receiving cavity 103. The second detection electrode 1022 is disposed opposite to the support section 2031. After the aerosol generating article 200 is removed, the capacitance value in the receiving cavity 103 will return to the capacitance value before the aerosol generating article 200 was inserted into the receiving cavity 103. Therefore, it can be determined whether the aerosol generating article 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 103, the aerosol will also be carried out of the accommodating cavity 103. 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 103, thereby determining that the aerosol generating product 200 has been removed.
[0156] Referring to Figure 16, in some embodiments, the detection electrode 102 includes one or more electrodes, and the plurality of detection electrodes 102 are respectively disposed at different positions of the receiving member 101. Step 021: Based on the detection information, detecting whether the aerosol generating article 200 has been pulled out includes:
[0157] Step 0213: 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;
[0158] Step 0214: 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;
[0159] Step 0215: If the time sequence and position sequence match, determine that the aerosol-generated product 200 has been removed.
[0160] Specifically, during the process of the aerosol generating article 200 being removed from the accommodating cavity 103, 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.
[0161] 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 103, 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.
[0162] 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 caused by the capacitance change caused by the front end 201 and the support section 2031 itself. Therefore, when the aerosol generating product 200 is removed, since the aerosol in the accommodating cavity 103 is basically carried out with the aerosol generating product 200, the residual aerosol in the accommodating cavity 103 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 103. 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 comparing the time sequence and position sequence of the changes of each detection electrode 102, the accuracy of detection is further improved. As shown in Figure 17, 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.
[0163] Please refer to Figure 18. In some embodiments, step 021, which involves detecting whether the aerosol-generating article 200 has been pulled out based on detection information, further includes:
[0164] Step 0216: Check if any sudden changes have occurred in the detection information;
[0165] Step 0217: If yes, then obtain the aspiration detection results within a preset time period containing the moment when the detection information changes abruptly;
[0166] Step 0218: 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;
[0167] Step 0219: 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.
[0168] 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.
[0169] The suction detection results can be used to determine whether the user has performed a suction action (removing aerosols).
[0170] The preset time period can be, for example, 3 seconds, 4 seconds, 5 seconds, 6 seconds, etc.
[0171] Specifically, during the heating process of the aerosol generating product 200, the aerosol generating product 200 is not completely atomized, and a large amount of aerosol remains in the accommodating cavity 103. If a sudden change in the detection information is detected at this time, the controller 104 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 considered 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 considered that the sudden change in the detection information may be caused by the aerosol generating product 200 being pulled out. It is necessary to 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, in order to perform further pull-out detection and avoid misjudgment. For example, please refer to Figures 17 and 19. Assume that 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. Assume that 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.
[0172] Please refer to Figure 20. In some embodiments, step 021: Based on detection information, detecting whether the aerosol generating article 200 has been pulled out includes:
[0173] Step 0216: Check if any sudden changes have occurred in the detection information;
[0174] Step 0217: If yes, then obtain the aspiration detection results within a preset time period containing the moment when the detection information changes abruptly;
[0175] Step 0218: 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;
[0176] Step 0221: 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.
[0177] 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 103, suction action, and aerosol generation product 200 being pulled out of accommodating cavity 103, 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.
[0178] Referring to Figure 21, in some embodiments, the controller 104 is also used for:
[0179] Step 022: Detect whether the trend of change in the detection information meets the preset trend;
[0180] Step 023: If yes, then confirm that a suction action has been detected;
[0181] Step 024: If not, then it is determined that no suction action was detected.
[0182] Optionally, the aerosol generating device 100 further includes a suction detection element for performing suction detection to obtain suction detection results.
[0183] 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 103, and the change trend of the capacitance information is reflected as an increase; after suction, the aerosol accumulates again, and the change trend of the capacitance information is reflected as a decrease).
[0184] 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 the airflow has changed in the accommodating cavity 103, that is, it can be considered that the user has performed suction.
[0185] It is understandable that in related technologies, when performing suction detection on aerosol generating devices, sensors (such as airflow sensors) are usually installed in the airway to determine the suction action based on changes in airflow in the airway.
[0186] For example, let's take a solution where an airflow sensor is installed within the airway as an example. The airflow sensor can be used to detect airflow in the airway. When a suction action occurs, the airflow within the airway accelerates, and the sensor responds to the change in airflow by generating different outputs, thereby detecting the suction action.
[0187] However, when the accuracy of the airflow sensor is low or the environment changes (such as changes in humidity or temperature), measurement errors may occur in the airflow sensor, affecting the accuracy of the detection.
[0188] In view of this, in some embodiments, the detection information includes capacitance information, which characterizes the capacitance change caused by the aerosol-generated article, and the suction state includes whether the aerosol-generated article is suctioned. For ease of understanding, the application scenarios of the technical solution of this application are further explained. Please refer again to Figure 1. The aerosol generation system 1000 includes an aerosol generation device 100 and an aerosol-generated article 200. The aerosol generation device 100 includes a receiving element 101 and a detection element 102. The receiving element 101 has a receiving cavity 103 for accommodating at least a portion of the aerosol-generated article 200. The aerosol generation device 100 also includes a controller 104, which can be used to execute the suction detection method.
[0189] 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 forms a receiving cavity that receives the aerosol generating matrix. The detection capacitor is disposed in the area opposite to the receiving member 101 and the medium segment 202.
[0190] The medium section 202 may be equipped with an aerosol generating product 200, which includes a matrix material capable of generating aerosols, such as tobacco, plant extracts (such as mugwort), etc. When the matrix material of the aerosol generating product 200 is heated by a heat source or subjected to physical atomization, it can release aerosols for use by the user.
[0191] The front-end component 201 can be used to prevent leakage of aerosols generated by the aerosol generating product 200.
[0192] The interior of the medium section 202 can form a closed containment cavity, which can be used to contain the aerosol generated by the aerosol generating product 200 to prevent the aerosol from being contaminated or damaged by the outside world.
[0193] Among them, functional segment 203 can come into contact with the user and can filter out impurities in aerosols, improving the user experience.
[0194] For example, referring again to Figure 8, taking functional segment 203, which includes a filtration segment 2032 and a cooling segment 2031, as an example, the aerosol-generating product 200 in the medium segment 202, when heated, can release high-temperature aerosols. The aerosols pass through the cooling segment 2031 and the filtration segment 2032 before contacting 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 the cooling segment 2031, the temperature of the aerosol is reduced, avoiding irritation and harm to the user and ensuring a better user experience. Aerosols generated from matrix materials often contain impurities such as tiny particles. By setting functional segments, the user experience can be further improved. Furthermore, functional segments can help regulate airflow, allowing the aerosol to enter the user's mouth more evenly.
[0195] Optionally, the aerosol generating article 200 may include a front end 201, a medium segment 202, and a functional segment 203. For example, referring to FIG1, the aerosol generating article 200 includes a front end 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 201.
[0196] Optionally, the aerosol generating article 200 may include a functional segment 203 and a medium segment 202. For example, referring to FIG3, the aerosol generating article 200 includes a medium segment 202 and a functional segment 203.
[0197] Optionally, step 120: Based on multiple detection information, detect the presence and / or suction status of the aerosol-generating article in the accommodating cavity, including:
[0198] Step 031: Based on the change in capacitance information, detect whether the aerosol-generated product 200 has been aspirated.
[0199] In other words, as shown in Figure 22, the aspiration detection method may include:
[0200] Step 030: Obtain capacitance information collected from the test specimen. The capacitance information characterizes the capacitance changes caused by the aerosol-generated product.
[0201] Step 031: Based on the change in capacitance information, detect whether the aerosol-generated product 200 has been aspirated.
[0202] 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.
[0203] The detection element 102 can be a capacitance detection device (e.g., a capacitance detection sensor). The detection element 102 can be used to collect capacitance information, which may include multiple capacitance values caused by the aerosol-generated product 200 over a certain period of time, capacitance change trends, etc.
[0204] It is understood that the detection element 102 can also be a detection device capable of collecting voltage information (such as voltage value and voltage change), current information (such as current value and current change), and temperature information (such as temperature value and temperature change). Taking the collection of voltage information by the detection element 102 as an example, the detection element 102 can collect voltage information (such as voltage value change) caused by aerosol products.
[0205] The capacitance change can include the capacitance change trend and the amount of capacitance change within a preset time period (e.g., the difference between the maximum and minimum values of the capacitance data within the preset time period). The capacitance information can be represented by a voltage value, and the capacitance change can be represented by the change in voltage value.
[0206] Since the detection element 102 exhibits different voltages for materials with different dielectric constants, the larger the dielectric constant of the detected material, the smaller the voltage output by the detection element 102.
[0207] It is understandable that the humidity at the detection point will affect the capacitance data collected by the detection element 102. By placing the detection element 102 in the area opposite to the dielectric section 202, or placing it at the front end 201, the characteristics of the dielectric section 202 and the front end 201 being non-hygroscopic can be utilized to avoid the detection element 102 being affected by moisture content, humidity, etc., which would lead to large differences in the obtained capacitance data and make it difficult to reflect the suction problem.
[0208] Specifically, the aerosol generating device 100 has a receiving cavity 103 within its accommodating member 101. The receiving cavity 103 can accommodate at least a portion of the aerosol generating product 200. The detection element 102 can output a corresponding value based on the dielectric constant of the material being detected. The aerosol generating device 100 can heat at least a portion of the aerosol generating product 200 within the receiving cavity 103. When the aerosol generating product 200 is heated, it releases aerosol. Without suction, the released aerosol accumulates, causing a change in the dielectric constant at the accumulation point. During suction, the accumulated aerosol is released, and the dielectric constant at the accumulation point also changes. The detection element 102 can collect capacitance information after accumulation and when the accumulation disappears. Based on the temporal changes in each capacitance value, it determines whether the aerosol generating product 200 has been suctioned. For example, based on whether the changes in each capacitance value meet a preset trend, if the changes in each capacitance value meet the preset trend, it is determined that the aerosol generating product 200 has been suctioned.
[0209] Thus, by acquiring the capacitance information collected by the detection element 102, which characterizes the capacitance change caused by the aerosol generating product 200, and then detecting whether the aerosol generating product 200 has been aspirated based on the change in capacitance information, since the aspiration action can cause a change in the concentration of the aerosol generating matrix, the capacitance information can respond to the concentration of the aerosol generating matrix. Therefore, detecting whether the aerosol generating product 200 has been aspirated based on the change in capacitance information can ensure the accuracy of the aspiration detection. Since the capacitance information is generated based on the change in electric field and dielectric constant caused by the aerosol generating product 200 being aspirated, the capacitance information is less affected by environmental changes (such as changes in humidity, temperature, etc.). Therefore, when detecting whether the aerosol generating product 200 has been aspirated based on the change in capacitance information, misjudgments caused by interference from the external environment can be avoided, ensuring the reliability of the detection results.
[0210] Referring to Figure 23, in some embodiments, the accommodating cavity 103 is used to accommodate the aerosol generating article 200, the aerosol generated by the aerosol generating article 200 when heated having a dielectric constant greater than that of air, and the controller 104 is also used to perform the following suction detection method:
[0211] Step 032: Determine whether the changing trends of multiple capacitance data meet the preset trends, which include decreasing first and then increasing;
[0212] Step 033: If yes, then it is confirmed that aspiration has been performed.
[0213] Specifically, let's take the example of a high voltage signal detected by the detector 102 when the aerosol generating product 200 is not releasing aerosols. When the aerosol generating product 200 is heated, it releases aerosols. Without suction, the aerosols accumulate outside the detector 102. Since the dielectric constant of the aerosols generated by the heated aerosol generating product 200 is greater than that of air, the dielectric constant gradually increases with the degree of accumulation, and the capacitance information output by the detector 102 can be represented by a gradually decreasing voltage signal (assumed to be defined as low voltage). During suction, the accumulated aerosols are rapidly carried away, the dielectric constant decreases rapidly, and the capacitance information output by the detector 102 can be represented by a rapidly increasing voltage signal. Therefore, for this change, the preset trend during suction can be set to include a trend of first decreasing and then increasing. By comparing the changing trends of multiple capacitance data collected by the detection element 102 with preset trends, if the changing trends match the preset trends (e.g., the changing trends and preset trends are the same), it is determined that the user has performed aspiration.
[0214] Referring to Figure 24, in some embodiments, the accommodating cavity 103 is used to accommodate the aerosol generating article 200, the aerosol generated by the aerosol generating article 200 when heated having a dielectric constant greater than that of air, and the controller 104 is also used to perform the following suction detection method:
[0215] Step 034: Determine whether the changing trends of multiple capacitance data meet the preset trends, which include decreasing first and then increasing, or increasing first and then decreasing.
[0216] Step 035: If the changing trends of multiple capacitance data meet the preset trend, determine whether the rate at which the capacitance data increases is greater than the preset rate;
[0217] Step 033: If the rate at which the capacitance data increases is greater than the preset rate, it is confirmed that suction has been performed.
[0218] The preset speed can be determined through experiments or by looking up tables, which can be used to determine the minimum rate of change of aerosols when suction occurs.
[0219] The rate at which the capacitance data increases can be the rate of change between the maximum and minimum values when the capacitance data changes. For example, please refer to Figure 25, which exemplarily illustrates the change in capacitance data during a pumping operation. The rate at which the capacitance data increases can be the rate of change from point a to point b.
[0220] Referring to Figure 26, optionally, the controller 104 can also be used to perform the following suction detection method:
[0221] Step 036: Obtain the maximum and minimum values of the capacitance data that show an increasing trend from the minimum to the maximum value among multiple capacitance data; and the time taken for the capacitance to increase from the minimum to the maximum value;
[0222] Step 037: Based on the difference between the maximum and minimum values and the increase time, calculate the speed at which the capacitance data increases.
[0223] Specifically, when a user draws in aerosols through the aerosol generating device 100, the aerosol concentration change typically exhibits rapid, continuous, and non-steady-state changes (as shown in Figure 6). During a single aerosol concentration change, the difference between the maximum and minimum aerosol concentration values can be represented as one draw. Therefore, the occurrence of a draw can be determined based on the minimum and maximum values of the capacitance data showing an increasing trend (at which point aerosol accumulation occurs, corresponding to the maximum aerosol concentration) and the maximum value (at which point the draw is complete and the aerosol is carried away, corresponding to the minimum aerosol concentration). Then, when calculating the rate of increase in capacitance data, the rate of increase can be obtained by calculating (maximum value - minimum value) / increase time using the difference between the maximum and minimum values of the capacitance data showing an increasing trend, and the increase time from the minimum to the maximum value. For example, referring to Figure 6, calculate (ba) / (Tb-Ta) based on the difference between the maximum value b and the minimum value a of the capacitance data that shows an increasing trend, and the increase time (Tb-Ta) from the minimum value a to the maximum value b, to determine the rate of increase of the capacitance data when the suction occurs.
[0224] Referring to Figure 25, when no suction occurs, aerosols accumulate; when suction occurs, aerosols are carried away; when suction stops, aerosols accumulate again; when suction occurs again, aerosols are carried away again… This accumulation and removal of aerosols is a cyclical process. Therefore, if the trend of multiple collected capacitance data follows a pattern of first increasing and then decreasing (first suction occurs, aerosols are carried away, then aerosols accumulate) (as shown in Figure 25, from b to a), suction can also be considered to have occurred. To further improve the accuracy of suction detection, the rate of increase in capacitance data (the rate at which aerosols are carried away) can be compared with a preset rate. If the rate of increase in capacitance data is greater than the preset rate, suction is determined to have occurred.
[0225] Referring to Figure 27, in some embodiments, the accommodating cavity 103 is used to accommodate the aerosol generating article 200, the aerosol generated by the aerosol generating article 200 when heated having a dielectric constant greater than that of air, and the controller 104 is also used to perform the following suction detection method:
[0226] Step 032: Determine whether the changing trends of multiple capacitance data meet the preset trends, which include decreasing first and then increasing;
[0227] Step 038: If the changing trends of multiple capacitance data meet the preset trend, determine whether the magnitude of the increase in capacitance data is greater than the preset magnitude and whether the speed is greater than the preset speed.
[0228] Step 033: If the increase in capacitance data is greater than the preset amplitude and the speed is greater than the preset speed, then it is determined that suction has been performed.
[0229] The preset amplitude can be the difference between the minimum and maximum values of the capacitance data during a preset time period (when the capacitance data changes). Alternatively, it can be the degree of change in the capacitance data (e.g., the rate of change, the absolute value of the rate of change, etc.).
[0230] Specifically, by comparing the changing trends of multiple capacitance data with a preset trend, if the changing trends match the preset trend (the changing trend satisfies the condition of first decreasing and then increasing), further detection is performed to determine whether to perform aeration. This not only improves the accuracy of detection but also reduces computation and saves computing power. When the changing trends of multiple capacitance data satisfy the preset trend, the amplitude and rate of change are calculated based on the acquired capacitance data. A comparison of the amplitude and rate of change with preset amplitudes and preset rates determines whether aeration should proceed. If the amplitude and rate of increase in capacitance data are greater than the preset amplitude and rate, it indicates that a sudden change has occurred in the aerosol, satisfying the changes required for aeration, thus confirming that aeration has been performed.
[0231] Referring to Figure 28, in some embodiments, the controller 104 is also used to perform the following suction detection method:
[0232] Step 039: Filter the multiple capacitance data collected by the detection component 102 to remove noisy capacitance data. Noisy capacitance data refers to the capacitance data with abnormal fluctuations among the multiple capacitance data.
[0233] Step 041: Based on the changing trend of multiple capacitance data after filtering, perform suction detection to obtain the suction detection result.
[0234] The suction detection is used to detect whether the user is suctioning the aerosol generating device 100.
[0235] Filtering can be used to remove capacitance data that interferes with the suction detection, thereby improving the accuracy of the suction detection. For example, filtering can include extreme value filtering and smoothing filtering.
[0236] The noise capacitance data can be abnormally fluctuating capacitance data caused by capacitance signal interference introduced by external environment, equipment, etc. For example, it could be a capacitance data that suddenly and drastically decreases during the process of increasing capacitance data detected by the detection device 102.
[0237] Specifically, by filtering multiple capacitance data collected by the detection device 102 (e.g., extreme value filtering, smoothing filtering, etc.), noisy capacitance data is removed, and capacitance data that better reflects the concentration and changes of aerosols is obtained. Based on the changing trend of multiple capacitance data after filtering, suction detection is performed to obtain suction detection results (including whether suction is performed), which can ensure the accuracy of suction detection.
[0238] Referring to Figure 29, in some embodiments, the aerosol generating apparatus 100 further includes a heating element for heating the receiving cavity 103, which is used to contain the aerosol generating article 200. During the insertion of the aerosol generating article 200 into the receiving cavity 103, different parts of the aerosol generating article 200 pass through the detection element 102, and the capacitance data collected by the detection element 102 is different. The controller 104 is also used to perform the following suction detection method:
[0239] Step 042: Based on the changing trends of multiple capacitance data, perform insertion detection to obtain the insertion detection results, which include whether the aerosol-generated product 200 has been inserted or not.
[0240] Step 043: With the aerosol generating product 200 inserted, control the heating element to heat up and perform suction detection.
[0241] The insertion detection is used to detect whether the aerosol generating product 200 is inserted into the accommodating cavity 103, and the suction detection is used to detect whether the user is suctioning the aerosol generating device 100.
[0242] The heating element can be a thermistor, etc.
[0243] Specifically, as described above, the aerosol generating article 200 may include a front end 201, a dielectric segment 202, and a functional segment 203, with the dielectric segment 202 located between the front end 201 and the functional segment 203; alternatively, the aerosol generating article 200 may also include a dielectric segment 202 and a functional segment 203. The front end 201, dielectric segment 202, and functional segment 203 have different dielectric constants. During the insertion of the aerosol generating article 200 into the receiving cavity 103, each part of the aerosol generating article 200 will sequentially pass through the detection element 102. The detection element 102 can collect different capacitance data. Based on the comparison between the changing trends of multiple capacitance data and a preset insertion trend, it is determined whether the aerosol generating article 200 has been inserted.
[0244] For example, taking an aerosol generating article 200 comprising a front-end component 201, a dielectric section 202, and a functional section 203, with a detection element 102 disposed within the accommodating cavity 103 and opposite to the functional section 203, let's assume that the capacitance data corresponding to the front-end component 201, the dielectric section 202, and the functional section 203 are low voltage, medium voltage, and high voltage, respectively, and the preset insertion change trend includes from low to medium and then to high. Then, during the insertion of the aerosol generating article 200 into the accommodating cavity 103, the detection element 102 sequentially... The front-end component 201, the dielectric section 202, and the functional section 203 are detected. In response to the detected aerosol generating product 200, the capacitance data output by the detection component 102 changes from low to medium and then to high, which is the same as the preset insertion change trend. Therefore, the insertion detection result of aerosol generating product has been obtained. When the aerosol generating product 200 has been inserted, the heating component (such as a thermistor) is controlled to heat the aerosol generating product 200 and suction detection is performed.
[0245] Referring to Figure 30, in some embodiments, the controller 104 is also used to perform the following suction detection method:
[0246] Step 044: If the suction test result indicates that suction has been performed, increment the suction count by 1, and delete or set the capacitance data used to obtain the suction test result to invalid data.
[0247] Step 045: After the preset number of suctions is reached, a prompt message is issued.
[0248] The preset number of times can be determined based on the total aerosol generation amount of the aerosol generating product 200 or the number of times (orifices) that the aerosol generating product 200 can be drawn.
[0249] The notification information can be used to inform the user of the remaining amount of aerosol that can be generated by the aerosol generating device 200, the remaining number of suction ports, etc. The notification information can be issued in the form of text, voice, light, etc. For example, a light-emitting diode (LED) can be set on the aerosol generating device 100, and the LED can be kept on (or flashing) as a notification information; another example is that a text notification information can be issued by a terminal (such as a mobile phone) that is connected to the aerosol generating device 100.
[0250] Specifically, the aerosol generating article 200 can generate a limited number of aerosols, and the number of suctions performed by the aerosol generating article 200 is related to the number of aerosols it can generate. When the suction detection result indicates that suction has been performed, the suction count is incremented by 1 (i.e., the suction count is accumulated), and the capacitance data used to obtain the suction detection result is deleted or set to invalid data to avoid the used capacitance data affecting the calculation of subsequent suction port numbers (e.g., causing duplicate counting). The accumulated suction count is then compared with a preset number of suctions. If the preset number of suctions is reached, a prompt message is issued.
[0251] Referring to Figure 31, to facilitate better implementation of the aerosol generating apparatus of this application, this application also provides a first insertion detection device 400. The first insertion detection device 400 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; the receiving cavity is used to contain the aerosol-generated product. The first insertion detection device 400 includes a first acquisition module 401 and a first detection module 402. The first acquisition module 401 is used to acquire multiple detection information collected by the detection element. The multiple detection information is 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 first detection module 402 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.
[0252] In some implementations, the first detection module 402 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.
[0253] In some implementations, the first detection module 402 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 decreasing first and then increasing or decreasing and maintaining a preset duration.
[0254] In some implementations, the first detection module 402 is further used to determine whether the changing trend of multiple detection information satisfies a second fluctuation trend, wherein the second fluctuation trend is to decrease and maintain a preset duration.
[0255] In some implementations, the first detection module 402 is further configured to determine whether the changing trend of the detection information collected by the plurality of first detection devices satisfies a first fluctuation trend; and / or whether the changing trend of the detection information collected by the plurality of second detection devices satisfies a second fluctuation trend; wherein the first fluctuation trend is first decreasing and then increasing, and the second fluctuation trend is decreasing.
[0256] In some implementations, the first detection module 402 is further configured to determine whether the changing trend of the detection information collected by the plurality of first detection devices satisfies a first fluctuation trend; and / or whether the changing trend of the detection information collected by the plurality of second detection devices satisfies a second fluctuation trend; and / or whether the changing trend of the detection information collected by the plurality of third detection devices satisfies 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.
[0257] Referring to Figure 32, to facilitate better implementation of the aerosol generating apparatus of this application, this application also provides a second insertion detection device 500. The second insertion detection device 500 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 insertion detection device 500 of the aerosol generating product 200. The second insertion detection device 500 includes a second acquisition module 501 and a second detection module 502. The second acquisition module 501 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 second detection module 502 is used to detect whether the aerosol generating product has been removed from the receiving cavity based on the detection information.
[0258] Referring to Figure 33, to facilitate better implementation of the aerosol generating apparatus of this application, this application also provides a suction detection device 600. The suction detection device 600 can be used in an aerosol generating apparatus, which includes a receiving element and a detection element. The receiving element has a receiving cavity for accommodating at least a portion of the aerosol-generated product. The aerosol generating apparatus also includes a controller. The suction detection device 600 includes a third acquisition module 601 and a third detection module 602. The third acquisition module 601 is used to acquire capacitance information collected by the detection element, the capacitance information representing the capacitance change caused by the aerosol-generated product. The third detection module 602 is used to detect whether the aerosol-generated product has been suctioned based on the change in capacitance information.
[0259] In some embodiments, the accommodating cavity is used to contain the aerosol generating article, the dielectric constant of the aerosol generated by the aerosol generating article being greater than the dielectric constant of air, and the suction detection device 600 further includes a determination module 603, which is used to determine whether the changing trend of multiple capacitance data meets a preset trend, the preset trend including first decreasing and then increasing; if so, it is determined that suction has been performed.
