[0001] Cross-reference of related applications

[0002] This application claims priority to Chinese Patent Application No. 202510200457.5, filed on February 21, 2025, entitled “Suction Threshold Adjustment Method and Aerosol Generating Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of aerosol generation technology, and in particular to a method for adjusting the suction threshold and an aerosol generation device. Background Technology

[0004] Existing aerosol generating devices typically have a function to calculate the number of suctions. By calculating the number of suctions based on the suction threshold, the device can be triggered to shut off heating, thereby ensuring consistent taste.

[0005] In one prior art example, the suction threshold includes a suction count threshold, which is preset in the aerosol generating device. When the suction count reaches the threshold, the aerosol generating device shuts off heating. However, the preset suction count threshold does not take into account the user's suction behavior. For example, if the user sucks too fast or too lightly, the aerosol generating matrix may not be fully heated when the aerosol generating device shuts off heating, resulting in waste of the aerosol generating matrix. Alternatively, if the user sucks too forcefully, a single suction consumes more aerosol generating matrix, leading to a poorer taste in subsequent suctions and thus poor consistency in taste.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0088] Please refer to Figure 1, which illustrates a suction threshold adjustment method provided in an embodiment of this application. This method is applied to an aerosol generating apparatus, which includes a heating component for heating an aerosol generating matrix to generate aerosols. As shown in Figure 1, the method includes:

[0089] Step S10: Obtain the suction threshold of the aerosol generating device. The suction threshold includes a single suction threshold and a suction count threshold. The single suction threshold is used to determine whether a single suction is effective, and the suction count threshold is used to trigger the aerosol generating device to shut down heating.

[0090] In some embodiments, the aerosol generating device is factory-set with initial suction thresholds, including an initial single suction threshold and an initial suction count threshold. In an optional embodiment, the initial suction threshold is determined based on usage data from a certain sample size of users.

[0091] Step S20: Determine whether the aerosol generating device has adjusted the suction threshold.

[0092] In this embodiment, the aerosol generating device includes a suction threshold adjustment mode and a normal operating mode. The user can select either the suction threshold adjustment mode or the normal operating mode by triggering a selection. When the user selects the suction threshold adjustment mode, the aerosol generating device adjusts the suction threshold and continues executing steps related to the suction threshold adjustment mode, such as S30. When the user selects the normal operating mode, the aerosol generating device starts heating, the user performs suction, and the initial suction threshold of the aerosol generating device is used to determine the effectiveness of a single suction and trigger the aerosol generating device to shut off heating.

[0093] In some embodiments, after the aerosol generating device adjusts the suction threshold, it triggers the selection to enter the normal working mode, the aerosol generating device starts heating, the user performs suction, and the effectiveness of a single suction is determined by the adjusted target suction threshold of the aerosol generating device, and the heating of the aerosol generating device is triggered to be turned off.

[0094] Step S30: If yes, then set the suction threshold to zero.

[0095] Step S40: Calculate the single suction parameters and the current suction count based on the electrical parameters of the heating component.

[0096] Step S50: Calculate the target suction threshold based on the single suction parameters of all single suctions during the heating process and the current number of suctions, and use the target suction threshold as the suction threshold of the aerosol generating device.

[0097] In this embodiment, the suction threshold is adjusted based on the user's suction behavior, making the suction threshold of the aerosol generating device more in line with the user's suction habits, thereby improving the utilization rate and taste consistency of the aerosol generating matrix.

[0098] In some embodiments, the aerosol generating device further includes a switching assembly. Referring to FIG2, step S20 includes the following steps:

[0099] Step S21: Obtain the start signal generated by the switch component in response to the start operation.

[0100] Step S22: Based on the start signal, activate the suction threshold adjustment function of the aerosol generating device, or activate the heating function of the aerosol generating device.

[0101] When the aerosol generating device adjusts the suction threshold, the suction threshold adjustment function is activated before the heating function, or the suction threshold adjustment function and the heating function are activated simultaneously.

[0102] In some embodiments, the suction threshold adjustment command is used to instruct the activation of the suction threshold adjustment function of the aerosol generating device, and the heating command is used to instruct the activation of the heating function of the aerosol generating device. In an optional embodiment, the suction threshold adjustment command is obtained to activate the suction threshold adjustment function of the aerosol generating device; the heating command is obtained to activate the heating function of the aerosol generating device. In an optional embodiment, both the suction threshold adjustment command and the heating command are obtained to activate both the suction threshold adjustment function and the heating function of the aerosol generating device.

[0103] It is understood that the activation signal is not limited to the switching components disclosed in the above embodiments. For example, the aerosol generating apparatus also includes a display module that generates an activation signal in response to an activation operation. As another example, the aerosol generating apparatus also includes an accelerometer that generates an activation signal in response to an activation operation.

[0104] In some embodiments, step S22 includes the following steps: based on the start signal, identifying the start operation as a first start operation or a second start operation; if identified as a first start operation, activating the suction threshold adjustment function and heating function of the aerosol generating device; if identified as a second start operation, activating the heating function of the aerosol generating device.

[0105] In some embodiments, the first activation operation includes continuously pressing the switch component a preset number of times, or continuously pressing the switch component for a first preset time; the second activation operation includes pressing the switch component once for less than a second preset time.

[0106] For example, pressing the switch assembly five times consecutively, or pressing it continuously for 5 seconds, activates the suction threshold adjustment function and heating function of the aerosol generator. Pressing the switch assembly for less than 1 second activates the heating function of the aerosol generator.

[0107] As one implementation method, please refer to Figure 3. Step S40 is achieved through the following steps:

[0108] Step S41: Based on the electrical parameters of the heating component, detect whether a single suction occurs.

[0109] Step S42: If a single suction occurs, detect the single suction parameter of the single suction and increment the current suction count by a natural number 1.

[0110] In this embodiment, the detection efficiency of single-stage suction is improved by using the electrical parameters of the heating component to detect whether a single-stage suction has occurred.

[0111] In some embodiments, step S40 further includes detecting whether a single aspiration is an abnormal aspiration behavior. If so, the single aspiration parameter for detecting a single aspiration is not executed, and the current aspiration count is incremented by a natural number 1. Abnormal aspiration behavior can be determined by the aspiration duration. Filtering abnormal aspiration behavior helps to make the aspiration threshold adjustment more objective and realistic in obtaining the target aspiration threshold.

[0112] In some embodiments, referring to Figure 4, step S41 includes the following steps:

[0113] Step S411: Based on the electrical parameters of the heating component, generate a time-relative unit energy diagram of the heating period from the start of heating to the current moment for the aerosol generating device.

[0114] Step S412: Detect whether a single pumping has occurred based on the time-relative unit energy map.

[0115] In some embodiments, referring to Figure 5, step S411 includes the following steps:

[0116] Step S4111: Sample the electrical parameters of the heating component based on the temperature control cycle of the aerosol generation device.

[0117] Step S4112: Calculate the relative unit energy at each sampling time based on the electrical parameters and temperature control cycle.

[0118] In some embodiments, the electrical parameters include voltage, current, and duty cycle. Based on the electrical parameters and the temperature control cycle, the relative unit energy at each sampling time is calculated using the following formula:

[0119] Q T =V T I T D0 (Formula 1)

[0120] Among them, Q T V represents the relative unit energy at sampling time T. T Let I be the voltage of the heating component at sampling time T. T D0 represents the current of the heating component at sampling time T, and D0 represents the duty cycle of the heating signal driving the heating component.

[0121] Assuming the temperature control cycle of the aerosol generation device is 20ms, the energy consumed by the heating component within 20ms is processed to obtain the relative unit energy. It can be understood that the relative unit energy is not the actual energy value, but rather a relative value per unit time.

[0122] Step S4113: Based on each sampling time and the relative unit energy at each sampling time, generate a time-relative unit energy diagram of the aerosol generating device from the start of heating to the current time.

[0123] Figure 6 shows a time-relative unit energy graph, where the horizontal axis represents time and the vertical axis represents the relative unit energy at each sampling time. The time-relative unit energy graph corresponds to the heating process (or the suction process or the suction threshold adjustment process). As shown in Figure 6, when the horizontal axis is 0, it indicates that the aerosol generating device has started heating; when the horizontal axis is 1000, it indicates that the aerosol generating device has stopped heating. Therefore, Figure 6 is used to show the relative unit energy changes during the heating process (or the suction process or the suction threshold adjustment process). The time-relative unit energy graph includes single suction graphs corresponding to each single suction, represented by waveform bulges. Figure 6 includes 13 single suction graphs. Assuming all 13 single suctions are effective, this indicates that the number of suctions in this heating process is 13.

[0124] As one implementation method, please refer to Figure 7. Step S40 is achieved through the following steps:

[0125] Step S43: Based on the electrical parameters of the heating component and the suction confirmation operation applied by the user to the aerosol generating device, detect whether a single suction has occurred.

[0126] Step S44: If a single suction occurs, detect the single suction parameter of the single suction and increment the current suction count by a natural number 1.

[0127] In this embodiment, the occurrence of a single suction is detected by the electrical parameters of the heating component and the suction confirmation operation applied by the user to the aerosol generating device, thus avoiding signal interference and improving the reliability of the single suction.

[0128] In some embodiments, referring to Figure 8, step S43 includes the following steps:

[0129] Step S431: Based on the electrical parameters of the heating component, generate a time-relative unit energy diagram of the heating period from the start of heating to the current moment for the aerosol generating device.

[0130] Step S432: Based on the time-relative unit energy diagram and the user's suction confirmation operation applied to the aerosol generating device, detect whether a single suction has occurred.

[0131] In some embodiments, referring to FIG9, the aerosol generating device further includes a switching assembly, and step S432 includes the following steps:

[0132] Step S4321: Obtain the suction confirmation signal generated by the switch assembly in response to the suction confirmation operation.

[0133] Step S4322: Detect whether the graph of the relative unit energy map has a single suction pattern within the third preset time period from the time corresponding to the suction confirmation signal.

[0134] Step S4323: If yes, then confirm that a single aspiration has occurred.

[0135] It is understood that the aspiration confirmation signal is not limited to being generated by the switching components disclosed in the above embodiments. For example, the aerosol generating apparatus also includes a display module that generates a start signal in response to the aspiration confirmation operation. As another example, the aerosol generating apparatus also includes an accelerometer that generates a start signal in response to the aspiration confirmation operation.

[0136] As one implementation method, please refer to Figure 10. Step S40 is implemented through the following steps:

[0137] Step S45: Based on the electrical parameters of the heating component, generate a time-relative unit energy diagram of the heating period from the start of heating to the current moment for the aerosol generating device.

[0138] Step S46: Based on the user's suction confirmation operation applied to the aerosol generating device, detect whether a single suction has occurred.

[0139] Step S47: If a single suction occurs, the single suction parameter of the single suction is detected according to the time-relative unit energy diagram, and the current suction count is incremented by a natural number 1.

[0140] In this embodiment, the user performs a suction confirmation operation on the aerosol generating device to detect whether a single suction has occurred, thus avoiding signal interference and improving the reliability of single suction.

[0141] In some embodiments, the aerosol generating device further includes a switching component that detects whether a single suction has occurred based on a suction confirmation operation applied by a user to the aerosol generating device, including: acquiring a suction confirmation signal generated by the switching component in response to the suction confirmation operation, and confirming that a single suction has occurred. In this embodiment, the single suction parameters of the single suction are detected according to a time-relative unit energy map, including: detecting the suction intensity and suction time of the single suction within a fourth preset time period from the time corresponding to the suction confirmation signal on the time-relative unit energy map.

[0142] In some embodiments, detecting single-pump parameters of a single pump includes: calculating the pumping intensity of a single pump based on the relative unit energy difference between the lowest and highest points of the single pumping graph in the time-relative unit energy map; and calculating the pumping time of a single pump based on the time difference between the lowest and highest points of the single pumping graph in the time-relative unit energy map.

[0143] For example, Figure 11 shows a single suction pattern corresponding to a single suction. The relative unit energy difference between the lowest and highest points of the single suction pattern is Qi, which is taken as the suction intensity of that single suction; the time difference between the lowest and highest points of the single suction pattern is Ti, which is taken as the suction time of that single suction. It is understood that the definition of suction intensity for a single suction is not limited to the energy change difference of a single suction disclosed in the above embodiments.

[0144] In some embodiments, referring to FIG12, step S50 includes the following steps:

[0145] Step S51: Determine whether the aerosol generating device actively shuts off the heating.

[0146] In some embodiments, determining whether the aerosol generating device actively shuts off heating includes: when the aerosol generating device shuts off heating, calculating the heating time of the aerosol generating device; determining whether the heating time reaches a preset heating time threshold; if yes, determining that the aerosol generating device passively shuts off heating; if no, determining that the aerosol generating device actively shuts off heating.

[0147] Step S52: If yes, select the minimum value of the single suction parameter of all single suctions in the heating process as the single suction threshold of the target suction threshold, and use the value of the current suction count minus 1 as the suction count threshold of the target suction threshold.

[0148] Step S53: If not, select the minimum value of the single suction parameter of all single suctions in the heating process as the single suction threshold of the target suction threshold, and use the current suction number as the suction number threshold of the target suction threshold.

[0149] Figure 13 is a time-suction intensity graph, with the horizontal axis representing time and the vertical axis representing the suction intensity of all single suctions. Based on the minimum value principle, the minimum value of the single suction parameter for all single suctions during the heating process is selected as the single suction threshold for the target suction threshold, as shown in Figure 13: Qi(min) = 39095. Figure 14 is a time-suction time graph, with the horizontal axis representing time and the vertical axis representing the suction intensity of all single suctions. Based on the minimum value principle, the minimum value of the single suction parameter for all single suctions during the heating process is selected as the single suction threshold for the target suction threshold, as shown in Figure 14: Ti(min) = 54.

[0150] If the aerosol generating device actively shuts off heating, it indicates that the last suction could not meet the user's needs. In this case, the current suction count minus 1 is used as the target suction count threshold. If the aerosol generating device passively shuts off heating, it indicates that the last suction still met the user's needs. In this case, the current suction count is used as the target suction count threshold. As shown in Figures 13 and 14, assuming the aerosol generating device actively shuts off heating, the suction count threshold is 13.

This device is applied to an aerosol generation apparatus, which includes a heating component for heating an aerosol generation matrix to generate aerosols. As shown in Figure 15, the suction threshold adjustment device 150 includes:

[0152] The acquisition module 151 is used to acquire the suction threshold of the aerosol generating device. The suction threshold includes a single suction threshold and a suction number threshold. The single suction threshold is used to determine whether a single suction is effective, and the suction number threshold is used to trigger the aerosol generating device to shut down heating.

[0153] The judgment module 152 is used to determine whether the aerosol generating device has adjusted the suction threshold.

[0154] The zeroing module 153 is used to set the suction threshold to zero when the aerosol generating device adjusts the suction threshold.

[0155] The calculation module 154 is used to calculate the single suction parameters and the current number of suctions based on the electrical parameters of the heating component.

[0156] The adjustment module 155 is used to calculate the target suction threshold based on the single suction parameters of all single suctions during the heating process and the current number of suctions, and to use the target suction threshold as the suction threshold of the aerosol generating device.
