[0035] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0036] In the related technology, the existing heat-not-burn devices usually need to preheat the aerosol-forming matrix before formal atomization to ensure the atomization ability and endurance of the heat-not-burn devices. However, due to the long total preheating time, in some scenarios, the long waiting time cannot meet the personalized needs of users, resulting in a low user experience.

[0037] In order to solve this problem, the present application has conducted an in-depth study of the preheating workflow of heat-not-burn devices, and found that the reason why the preheating time of heat-not-burn devices is long is that the lowest voltage (e.g., 3.5V) and full power output are usually used during the heating process. That is, the real-time temperature is calculated by using the temperature coefficient of resistance (TCR) through the change in the resistance of the heating element, and the temperature is controlled and adjusted by a proportional-integral-derivative controller (PID) to ensure that the temperature is stable at the target set value. Although this can ensure the consistency of suction and the endurance of the device, the lower voltage value also causes the heat-not-burn device to go through a longer preheating stage when it is used for the first time, which is usually more than 20 seconds. For users who are eager to use the heat-not-burn device, this 20-second wait is undoubtedly long.

[0038] Based on this, the present application proposes a control method for a heat-not-burn appliance, which can shorten the preheating time to meet the personalized needs of users in specific scenarios and enhance the user experience. The control method proposed in the present application will be described below through specific embodiments.

[0039] The control method of the heat-not-burn appliance provided by the embodiments of the present application is mainly applied to a heat-not-burn appliance. When the heat-not-burn appliance is provided with a processor, the execution subject of this control method is the processor. Among them, the processor may include a field-programmable gate array (FPGA), an analog circuit, a microcontroller unit (MCU), etc.

[0040] In some embodiments, in addition to being provided with a processor, the heat-not-burn appliance is further provided with a heating component and a power supply component. The heating component is configured to heat the aerosol-forming substrate, and the power supply component is configured to supply power to the heating component so that the heating component heats up.

[0041] Based on the heat-not-burn appliance in the above embodiments, in order to illustrate the technical solutions proposed in the present application, each embodiment will be described below with the MCU of the heat-not-burn appliance as the execution subject.

[0042] Figure 1 The schematic flowchart of the control method of the heat-not-burn appliance provided by the present application is shown. The control method of the heat-not-burn appliance includes:

[0043] Step 110: After receiving the preheating instruction, the MCU determines the preheating mode of the heat-not-burn appliance.

[0044] Step 120: The MCU controls the power supply component to supply power to the heating component with the supply voltage and supply power corresponding to the preheating mode.

[0045] To adapt to different usage scenarios and user preferences, the heat-not-burn appliance supports multiple preheating modes including the burst mode, and each mode corresponds to a set of specific power supply parameters (supply voltage and supply power). Therefore, before the preheating starts, for example, after receiving a preheating instruction triggered by the user through a voice instruction or a physical button, the MCU can first determine the current preheating mode, so as to achieve precise preheating control according to the corresponding parameters.

[0046] After the preheating mode is determined, the MCU controls the power supply component to work according to the power supply parameters in this mode, and provides a matching voltage and power for the heating component. For example, when the preheating mode is the burst mode, the MCU can control the power supply component to output at the actual voltage and full power, so as to realize the rapid temperature rise of the heating component, thereby shortening the preheating time and meeting the user's demand for rapid heating in specific scenarios.

[0047] Step 130: When the heating component finishes preheating the aerosol-forming substrate, a first prompt message is generated.

[0048] After the heating component completes the preheating of the aerosol-forming substrate, the MCU can generate a first prompt message to clearly inform the user that the device has entered a usable state, thereby enhancing the operation convenience and human-computer interaction experience. This prompt message helps prevent the user from making incorrect operations when the preheating is not completed or from having a sense of uncertainty during the waiting process.

[0049] Exemplarily, the MCU can control one or more of the components such as the indicator light, speaker, motor, or display screen configured in the heat-not-burn smoking device to work, so as to output prompt content in the form of sound prompts, vibration feedback, light changes, or screen icons, clearly conveying status information such as "preheating completed" or "can start using", and realizing clear and intuitive interaction feedback.

[0050] In this embodiment, to meet the personalized needs of users in specific scenarios, the heat-not-burn appliance is configured with a burst mode as a preheating mode. After receiving the preheating instruction, the control method first determines the corresponding preheating mode, and controls the power supply component to supply power to the heating component at a matching voltage and power according to the preheating mode. If the selected preheating mode is the burst mode, the power supply component will output at the actual voltage and full power, enabling the heating component to complete preheating in a short time, thereby enhancing the user experience in different scenarios. After the heating component completes the preheating of the aerosol-forming substrate, the heat-not-burn appliance can generate a first prompt message to indicate that the preheating is completed. The user can directly obtain the preheating completion status, avoiding incorrect operations and waiting anxiety, and overall optimizing the use convenience and interaction perception of the heat-not-burn appliance.

[0051] In some embodiments, the heat-not-burn appliance further includes an adjustment module, which is used to adjust the preheating mode of the heat-not-burn appliance from the default mode to the target mode before the heating component completes the preheating of the aerosol-forming substrate; wherein, the target mode at least includes the burst mode.

[0052] Exemplarily, the user can, before triggering the preheating instruction, adjust the preheating mode from the default mode to the burst mode based on the adjustment module.

[0053] Exemplarily, during the process of the MCU controlling the power supply component to heat the heating component based on the default mode, the user can, through the adjustment module, adjust and switch the preheating mode from the default mode to the burst mode.

[0054] That is to say, as long as before the preheating is completed, the user can flexibly and independently switch the preheating mode through the adjustment module, so that the MCU can dynamically adjust the power supply parameters according to the updated preheating mode and precisely control the heating process. This flexible mechanism not only meets the personalized needs of users in different scenarios, but also further improves the operation freedom and use experience of the device.

[0055] In some embodiments, the adjustment module includes an adjustment input sub-module and an adjustment indication sub-module. Specifically, the MCU can implement the adjustment of the preheating mode through this adjustment module:

[0056] Step A1, the MCU sets the target flag corresponding to the target mode based on the adjustment instruction received by the adjustment input sub-module.

[0057] The user can adjust the preheating mode at any time before the preheating is completed. Specifically, the user can send an adjustment instruction through the adjustment input sub-module (such as a voice recognition module, a physical button, etc.). After the MCU receives the adjustment instruction, it can set the target flag corresponding to the selected target preheating mode, which serves as the basis for identifying and applying this target mode in the subsequent control process. The setting of the target flag ensures that the adjustment instruction triggered by the user is accurately recorded and recognized, laying a foundation for the MCU to adjust the power supply parameters of the heating component according to the preheating mode.

[0058] Step A2, the MCU controls the output of the second prompt message based on the target flag.

[0059] Based on the mapping relationship between the target mode and the target flag, the MCU can control the adjustment indication sub-module to output the second prompt message, so as to visually feedback the current preheating mode to the user, and feedback it to the user in an intuitive way, so that the user can clearly know which preheating mode the current device is in, ensuring the transparency and controllability of the operation.

[0060] Exemplarily, the adjustment indication sub-module can be one or more components among the indicator light, speaker, motor or display screen configured in the heated tobacco product. Correspondingly, the second prompt message can be one or more forms of prompt content such as sound prompt, vibration feedback, light change or screen icon.

[0061] In this embodiment, before the heating component completes preheating, the user can send an adjustment instruction for the preheating mode to the adjustment input sub-module by means of voice or button, etc. After the MCU receives the adjustment instruction, it can set the target flag corresponding to the target mode, which is convenient for realizing preheating control based on the target flag. Subsequently, the MCU controls the adjustment indication sub-module to visually display the current preheating mode to the user in the form of the second prompt message such as voice, vibration or LED light, etc., which can realize the timely feedback of the preheating mode switching, and then improve the operation flexibility and interaction experience of the user.

[0062] In some embodiments, if the preheating mode is not switched to the burst mode, then the MCU will control the power supply component to supply power to the heating component in the default mode, that is, control the power supply component to supply full power to the heating component at a preset voltage. This preset voltage is lower than the actual voltage of the power supply component and is usually the lowest voltage of the power supply component. Therefore, compared with the burst mode, in the default mode, the heating component takes a longer time to complete the preheating of the aerosol-forming matrix.

[0063] In some embodiments, in order to accurately determine whether a heat-not-burn appliance can be started, the MCU may perform the following steps:

[0064] Step B1: The MCU periodically obtains the temperature of the heating component to calculate the cumulative energy output by the heating component.

[0065] To grasp the heating state of the heating component in real time, the MCU can periodically read the temperature of the heating component at a certain time interval to estimate the cumulative energy output by the heating component during the preheating process. The calculation of the cumulative energy can provide basic data support for subsequent judgment of whether the preheating is completed, which helps to improve the heating control accuracy.

[0066] Step B2: When the cumulative energy reaches the preset total preheating energy, the MCU determines that the heating component has completed preheating of the aerosol-forming substrate to which it belongs.

[0067] When it is detected that the cumulative energy output by the heating component has reached the threshold of the preset total preheating energy, the MCU can determine that the preheating process is completed, that is, the heating component already has the temperature conditions and energy accumulation required for aerosol formation. At this time, the MCU can generate a first prompt message to clearly convey status information such as "preheating completed" or "ready to use", realizing clear and intuitive interaction feedback.

[0068] Among them, the total preheating energy can be determined based on the energy empirical value required for preheating in the default mode. This value has been actually tested and optimized, and can effectively guide the judgment of the preheating process.

[0069] In this embodiment, in order to accurately determine whether a heat-not-burn appliance can be started, the MCU first periodically obtains the temperature data of the heating component, and accumulates the output energy of the heating component by calculating the temperature and the power supply parameters. When the cumulative energy reaches the preset total preheating energy, the MCU determines that the heating component has completed preheating of the aerosol-forming substrate, thereby ensuring that the heat-not-burn appliance enters the ready-to-use state as soon as possible, and providing a reliable basis for subsequent operations.

[0070] In some examples, periodically obtaining the temperature of the heating component to calculate the cumulative energy output by the heating component includes:

[0071] Step C1: The MCU calculates the actual temperature of the heating component based on the ambient temperature, the initial resistance value, the actual resistance value, and the temperature coefficient of resistance of the heating component.

[0072] The temperature change of the heating component is directly related to the energy accumulation during the preheating process. Therefore, in order to accurately estimate the temperature change during the preheating process and further estimate the energy output of the heating component, the MCU can determine the actual temperature of the heating component through the following formula:

[0073]

[0074] T1 is the actual temperature; R2 is the actual resistance of the heating component, which can be calculated by the ratio of the value collected by ADC and the battery voltage; R1 is the initial resistance of the heating component (obtained during calibration); TCR is the temperature coefficient of resistance, which shows the relative rate of change of resistance with temperature, in units of ppm / ℃; T0 is the room temperature during calibration (stored in the register FLASH).

[0075] Step C2: The MCU calculates the accumulated energy based on the actual temperature, the accumulated preheating time of the heating component and a preset formula.

[0076] In each sampling period, that is, within 100ms, the MCU can bring the actual temperature T obtained every 100ms and the corresponding current time t into the energy calculation function, and estimate the cumulative energy E currently output by the heating component by integration. The basic idea of ​​energy calculation is to integrate the "thermal power" under the temperature-time curve, and the expression is as follows:

[0077]

[0078] After obtaining the actual temperature (T1) of the heating component, the MCU can calculate the cumulative energy of the heating component based on the actual temperature and the preset cumulative preheating time. The specific calculation formula is as follows:

[0079]

[0080] E is the accumulated energy, ΔT i is the temperature difference between the current moment and the previous moment; Δt i is the sampling time interval (such as 0.1s).

[0081] In this embodiment, the MCU accurately determines the heating process by regularly obtaining the temperature of the heating component and calculating the cumulative energy. In order to ensure the accuracy of the cumulative energy estimation, the MCU first calculates the actual temperature of the heating component based on the ambient temperature, the initial resistance value of the heating component, the actual resistance value and the resistance temperature coefficient. Then, the MCU combines the actual temperature and the preheating time to calculate the cumulative energy of the heating component through a preset formula. In this way, the MCU can monitor the energy accumulation during the preheating process in real time, ensure that the heating component reaches the predetermined total preheating energy, and thus accurately determine whether the preheating is completed, and connect to ensure the normal use of the heating-not-burning appliance.

[0082] In some embodiments, in some extreme cases, such as the appliance is used at an extremely low ambient temperature, resulting in the cumulative energy failing to reach the total preheating energy for a long time, or there is a problem with the software calculation and the cumulative energy calculation is easily affected by the fluctuation of multiple parameters, which introduces errors and causes the cumulative energy calculation to be incorrect, which may lead to misjudgment of the preheating completion timing in the burst mode. In order to deal with these situations, after executing step B1, the MCU further includes:

[0083] Step D1: When the accumulated energy does not reach the total preheating energy, the MCU determines whether the accumulated preheating time of the heating component exceeds the preset total preheating time.

[0084] Step D2: When the accumulated preheating time exceeds the total preheating time, the MCU determines that the heating component has completed preheating the aerosol-forming substrate.

[0085] When the cumulative energy of the heating component has not yet reached the preset total preheating energy, the MCU can further monitor the total preheating time and determine the preheating status by judging whether the cumulative preheating time exceeds the preset total time. Compared with the default mode, the voltage in the burst mode is higher, so it can be considered that the cumulative preheating time in the burst mode is shorter than the total preheating time in the default mode. Based on this, if the cumulative preheating time has reached the preset total preheating time, it means that the heating component has completed the preheating process. At this time, the cumulative energy may not have fully reached the total preheating energy, which may be the above-mentioned extreme situation. Therefore, the MCU can determine that the heating component has completed the preheating of the aerosol forming matrix.

[0086] In this embodiment, by combining the two criteria of accumulated energy and accumulated preheating time, the MCU can more accurately determine whether the heating component has completed preheating, thereby improving the accuracy of the preheating completion judgment and ensuring the reliability and user experience of the heating-without-burning appliance.

[0087] In some embodiments, after the preheating stage, the MCU can control the heat-not-burn device to enter the suction stage. In this stage, the MCU determines the target temperature corresponding to the current moment according to the set temperature curve, and adjusts the power supply parameters accordingly to control the power supply component to accurately supply power to the heating component. By dynamically tracking the target temperature and adjusting the voltage and power output in real time, the heating component can be continuously maintained in a suitable temperature range, thereby ensuring the stability and consistency of the aerosol generation process and improving the user's suction experience.

[0088] In some embodiments, see Figure 2 In combination with the above embodiments, a preferred control method for a heating-without-combustion appliance includes:

[0089] Step 201: When a physical button of the heat-not-burn smoking device is short-pressed for a preset number of times, the MCU controls the motor to vibrate and sends an adjustment instruction to the adjustment input submodule.

[0090] When the physical button of the heat-not-burn tobacco device is short-pressed for a preset number of times, the MCU can control the motor to generate vibration feedback and send the corresponding adjustment command to the adjustment input submodule to switch the preheating mode from the default mode to the burst mode. The preset number of button presses can be set according to actual usage requirements. For example, it can be set to trigger the adjustment operation after three short presses. To avoid accidental touches or misjudgments, the duration of the short press can also be set to less than a certain time limit (such as 1 second).

[0091] Step 202: The MCU sets the flag bit corresponding to the burst mode to zero based on the adjustment instruction received by the adjustment input submodule, and switches the LED of the heating-not-burning appliance from white to green.

[0092] The MCU can switch the current preheating mode based on the adjustment instructions received by the adjustment input submodule. When receiving the adjustment instruction for exiting the burst mode, the MCU switches the flag from 0 in the default mode to 1 in the burst mode; accordingly, the color of the LED light of the heat-not-burn appliance is synchronously controlled to switch from white in the default mode to green in the burst mode, which is used to intuitively prompt the user that the current preheating mode is the burst mode. Through the linkage between the flag and the LED status, the user can clearly identify the current mode status, improving the convenience of interaction and the accuracy of operation.

[0093] Step 203: When the physical button is long pressed, the MCU obtains a flag bit.

[0094] The long press duration can also be set to be greater than the preset duration, such as 3 seconds, to start the heating process of the heat-not-burn device. The heating process can be divided into two stages according to the temperature curve, the first stage is the preheating stage, and the second stage is the inhalation stage. The acquisition of the flag bit is to determine the power supply mode of the power supply component to the heating component in the preheating stage, so as to achieve precise heating and meet the needs of users who want to quickly use the heat-not-burn device.

[0095] Step 204: The MCU determines whether the flag bit is zero.

[0096] Since the preheating mode includes two types: the default mode and the burst mode, the MCU can quickly determine the current preheating mode by judging whether the flag bit is zero. If the flag bit is 0, it means the current is the default mode; if the flag bit is 1, it means the current is the burst mode. Based on the mode recognition result, the MCU can select the power supply parameters (such as voltage and power) that match the current mode to control the power supply component to accurately supply power to the heating component, so as to ensure the consistency between the heating efficiency and the user's needs, and ensure that the operation logic of the heated non-combustion appliance is clear and reliable in different modes.

[0097] Step 205: The MCU determines that the flag bit is zero and determines that the power supply voltage is the lowest voltage of the power supply component.

[0098] The flag bit being zero indicates that the preheating mode is the default mode. At this time, in order to ensure the consistency of suction during the suction stage and the battery life of the heating component, the MCU can set the power supply voltage to the lowest voltage of the power supply component, such as 3.5V. Correspondingly, the power supply component will supply full power to the heating component at the lowest voltage.

[0099] It should be noted that in the default mode, the cumulative preheating duration is used as the judgment parameter for preheating completion. It is compared with the total preheating duration. When the cumulative preheating duration reaches the total preheating duration, it can directly jump to the subsequent step 210.

[0100] Step 206: The MCU determines that the flag bit is not zero and supplies full power to the heating component at the actual voltage of the power supply component.

[0101] The flag bit not being zero indicates that the preheating mode is the burst mode. At this time, in order to ensure the preheating efficiency and shorten the required preheating duration, the MCU can set the power supply voltage to the actual voltage of the power supply component. Correspondingly, the power supply component will supply full power to the heating component at the actual voltage. Among them, the power calculation formula can be written as p is the output power of the power supply component, U is the set power supply voltage, and R is the resistance value of the heating component. When the resistance value is certain, the higher the voltage, the greater the heating power. Therefore, the burst mode can reach the preheating temperature faster and meet the user's rapid use requirements in specific scenarios.

[0102] Step 207: The MCU calls the temperature calculation function of the heating component once every 100ms and outputs the actual temperature T.

[0103] The MCU calls the temperature calculation function of the heating component once every 100ms to monitor the heating status in real time and output the current actual temperature T. The specific calculation formula can refer to the foregoing formula.

[0104] Step 208: The MCU accumulates the energy E based on the actual temperature T, the current time t, and the preset formula.

[0105] The calculation formula of the accumulated energy can refer to the above-mentioned embodiment.

[0106] Step 209: The MCU determines whether the accumulated energy exceeds the total preheating energy.

[0107] Step 210: The MCU determines that the accumulated energy exceeds the total preheating energy, controls the motor to vibrate, and enters the suction stage.

[0108] In order to accurately determine whether preheating is completed in burst mode, the MCU can compare the accumulated energy with the total preheating energy. If the MCU determines that the accumulated energy exceeds the total preheating energy, it means that preheating is complete. At this time, the motor can vibrate to prompt the user to start inhaling and enter the inhalation stage.

[0109] Step 211, the MCU determines that the accumulated energy does not exceed the total preheating energy, and determines whether the accumulated preheating time exceeds the total preheating time.

[0110] If the cumulative energy does not reach the total preheating energy, in order to deal with extreme situations such as using the appliance at extremely low ambient temperature or software calculation problems, the cumulative preheating time can be compared with the total preheating time. Compared with the default mode, the voltage in the burst mode is higher, so it can be considered that the cumulative preheating time in the burst mode is shorter than the total preheating time in the default mode. Based on this, if the cumulative preheating time has reached the preset total preheating time, it means that the heating component has completed the preheating process. At this time, the cumulative energy may not have fully reached the total preheating energy. The above-mentioned extreme situation may have occurred. The MCU can determine that the heating component has completed the preheating of the aerosol-forming matrix. After the preheating is completed, step 210 can be executed.

[0111] On the contrary, when the accumulated preheating time does not exceed the total preheating time, it means that the preheating has not been completed yet, and the process can return to step 208 .

[0112] In this embodiment, in order to meet the personalized usage needs of users in different scenarios, the heat-not-burn smoking device adds a burst mode, and users can choose the preheating mode according to their own preferences. In the burst mode, the MCU controls the power supply component to supply power to the heating component at the actual voltage and full power, which significantly shortens the preheating time, improves the startup response speed, and enhances the user experience. In the default mode, the MCU controls the power supply component to supply power at the lowest voltage and full power to balance the power supply efficiency and the power consumption of the device, and ensure the temperature stability and the endurance of the whole machine in the subsequent suction stage.

[0113] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
