Description

[0002] During the operation of the aerosol generating device, the preheating stage is extremely critical and directly affects the final atomization effect.

[0003] The current preheating control method is to adjust the output energy of the aerosol generating device by changing the temperature or duration. On the one hand, due to the lack of precise calculation when changing the temperature, it is difficult to determine the appropriate temperature value, which can easily cause the atomized medium components to be unable to fully penetrate. On the other hand, although changing the duration can regulate the energy to a certain extent, there is still the problem of inaccurate calculation, which makes it impossible to keep the atomization duration consistent each time, affecting the user experience.

[0067] First, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0068] An aerosol generating device is a small device that converts liquid into aerosol through electronic technology. It is mainly composed of components such as batteries, heating elements, control elements, atomizers and atomizing media.

[0069] The above is a brief introduction to the nouns involved in the embodiments of the present application, which will not be repeated below.

[0070] This application example provides an example of a preheating control method for an aerosol generating device, please refer to Figure 1 As shown, Figure 1 A schematic flow chart of a preheating control method for an aerosol generating device provided by the present application is shown. As an example but not a limitation, the method can be applied to or run in an aerosol generating device. The method includes:

[0071] S101 , in response to a user's instruction to start heating the aerosol generating device, controlling the aerosol generating device to operate in a preheating mode based on a first set temperature.

[0072] S102 , when the aerosol generating device operates in a preheating mode based on a first set temperature, determining a cumulative output energy and a cumulative preheating time of the aerosol generating device.

[0073] S103: determining a remaining preheating time of the aerosol generating device based on the accumulated preheating time and a predetermined total preheating time of the aerosol generating device.

[0074] S104: Based on the remaining preheating time and the second set temperature, determine the estimated output energy of the aerosol generating device in the preheating mode based on the second set temperature.

[0075] S105 , determining whether to control the aerosol generating device to operate in a preheating mode based on a second set temperature according to the accumulated output energy and the estimated output energy.

[0076] Optionally, in the aerosol generating device provided by the example of the present application, the second set temperature is lower than the first set temperature, that is, the first set temperature is higher, in order to quickly make the components in the atomizing medium reach a state where they can be effectively volatilized in the early stage of preheating. For example, the value range of the first set temperature can be 250-300°C. The second set temperature is relatively low, which is to stably maintain the volatilization state of the components in the atomizing medium in the later stage of preheating, and avoid undesirable situations such as excessive volatilization of the components due to excessive temperature. For example, the value range of the second set temperature can be 200-230°C, so that the atomizing medium can be continuously released in a relatively gentle manner to ensure the stability of the atomization process.

[0077] It should be noted that the above temperature range is only an example, and the actual temperature setting may vary depending on many factors such as the specific design of the aerosol generating device, the composition and characteristics of the atomizing medium, and the user's taste requirements.

[0078] In the example of the present application, when the user triggers the start heating function of the aerosol generating device (for example, by pressing a specific button on the aerosol generating device or by operating a touch button, etc.), the control element of the aerosol generating device receives the start heating instruction. Then, the control element sends a heating instruction to the heating component, instructing the heating component to start heating based on the first set temperature (pre-set and stored in the aerosol generating device), thereby controlling the aerosol generating device to enter the preheating mode.

[0079] In an optional example, after the aerosol generating device enters the preheating mode, the indicator light on the aerosol generating device can be controlled to light up or the screen can display a prompt message to inform the user that the aerosol generating device has entered the preheating state.

[0080] During the process of the aerosol generating device running the preheating mode based on the first set temperature, the circuit system or the dedicated energy monitoring module inside the aerosol generating device monitors the power value output by the heating component during the operation in real time, and determines the cumulative output energy by integrating the power and time. For example, the power value of the heating component is measured once every very short time interval (such as a few milliseconds), and then the power value is multiplied by the time interval to obtain the output energy within this time interval, and the output energy of these time intervals is continuously accumulated to obtain the cumulative output energy.

[0081] When the aerosol generating device runs the preheating mode based on the first set temperature, the timer inside the aerosol generating device starts timing. The timer can be a timing function based on a hardware clock circuit or implemented by software. As the preheating mode proceeds, the time that has passed is continuously recorded to obtain the cumulative preheating time. Since the aerosol generating device pre-stores the total preheating time, this parameter can be determined based on factors such as the design specifications of the aerosol generating device and the characteristics of the atomizing medium and solidified in the storage chip of the aerosol generating device. The remaining preheating time can be obtained by subtracting the calculated cumulative preheating time from the total preheating time. For example, if the total preheating time is set to 30 seconds and the current cumulative preheating time is 10 seconds, the remaining preheating time is 20 seconds.

[0082] Since the second set temperature is pre-set and stored in the aerosol generating device, the energy expected to be output within the remaining preheating time if the aerosol generating device is switched to the preheating mode based on the second set temperature, that is, the expected output energy, can be calculated based on the second set temperature and the remaining preheating time.

[0083] Afterwards, the current preheating total energy is calculated based on the cumulative output energy and the expected output energy, and then the predetermined preheating total energy preset by the aerosol generating device is obtained (this energy value is determined based on the ideal preheating temperature curve and the atomizing medium preheating requirements), and then the current preheating total energy is compared with the predetermined preheating total energy.

[0084] If the current preheating total energy is greater than or equal to the predetermined preheating total energy, it means that according to the current energy accumulation, the aerosol generating device has reached or exceeded the ideal preheating energy state, and the control element sends an instruction to the heating component to switch the heating temperature from the first set temperature to the second set temperature, and continue to execute the preheating mode based on the second set temperature. If the current preheating total energy is less than the predetermined preheating total energy, the heating component is instructed to continue to operate the preheating mode based on the first set temperature, and the above-mentioned calculation and comparison process of cumulative output energy, cumulative preheating time, remaining preheating time, and expected output energy are repeated until the switching condition is met.

[0085] The example of this application indirectly determines the temperature switching timing based on energy calculation. It is no longer a simple adjustment of the preheating temperature based on the initial temperature, but a comprehensive consideration of the energy requirements of the entire preheating process, combining temperature with time and energy. For example, by calculating the relationship between the cumulative output energy and the estimated output energy based on the remaining preheating time and the second set temperature, it is determined when to switch from the first set temperature to the second set temperature, making the temperature control more scientific and accurate, and effectively avoiding the problem of non-transmittance or excessive volatilization of components due to inaccurate temperature calculation.

[0086] Through the preheating control method provided in the example of this application, the cumulative output energy, the expected output energy, and the comparison and temperature switching decisions based on the preset total preheating energy are accurately calculated, which can more accurately control the output energy of the aerosol generating device during the entire preheating process, and help ensure that each preheating can be completed within the ideal energy range, so that the components in the atomization medium of the aerosol generating device can be more stably and fully activated and released.

[0087] A two-stage preheating strategy of high temperature first and low temperature later is adopted. In the first stage, a higher temperature is used to quickly increase the temperature of the atomizing medium, prompting the internal components of the atomizing medium to begin initial volatilization and preparation, and then switch to the low temperature stage for stable and continuous heating. This not only avoids problems such as excessive volatilization of components that may be caused by long-term high temperature, but also effectively utilizes energy, improves the overall preheating efficiency, and reduces unnecessary energy waste and problems such as long preheating time.

[0088] Since the entire preheating process is based on scientific energy calculation and temperature switching mechanism, the preheating effect each time can be closer to the ideal state. Regardless of the initial state of the aerosol generating device (such as the initial temperature), it can provide users with relatively stable atomization experience such as concentration, temperature and taste, thereby enhancing users' product satisfaction with the aerosol generating device.

[0089] For a possible implementation, please refer to Figure 2 As shown, Figure 2 : is a flow chart of an optional preheating control method of an aerosol generating device provided in an embodiment of the present application, and determines whether to control the aerosol generating device to run a preheating mode based on a second set temperature according to the accumulated output energy and the expected output energy, including:

[0090] S201, calculating the current total preheating energy of the aerosol generating device according to the accumulated output energy and the estimated output energy.

[0091] S202 : Obtaining a predetermined total preheating energy of the aerosol generating device, wherein the predetermined total preheating energy is used to represent a total energy predetermined to be output when the aerosol generating device executes a preheating mode based on a preheating temperature curve.

[0092] S203: Based on a comparison result of the current preheating total energy and the predetermined preheating total energy, determine whether to control the aerosol generating device to operate in a preheating mode based on a second set temperature.

[0093] In the above specific implementation, the cumulative output energy is the total energy actually output by the aerosol generating device during the preheating mode based on the first set temperature. For example, the cumulative output energy can be, but is not limited to, obtained by continuous accumulation through an energy monitoring mechanism inside the aerosol generating device (such as integrating the heating power over time). The estimated output energy is calculated based on the remaining preheating time and the second set temperature, that is, if the preheating mode is subsequently switched to the second set temperature, the energy that needs to be output is estimated.

[0094] In the example of this application, when the current preheating total energy is calculated based on the accumulated output energy and the expected output energy, the two are usually added together. For example, if the accumulated output energy is E1 (the unit can be joule or other energy units) and the expected output energy is E2, then the current preheating total energy E_total is equal to E1+E2, that is, a total value that comprehensively considers the energy that has been output and the energy that is expected to be output in the future is obtained, so as to compare with the predetermined preheating total energy.

[0095] It is still necessary to explain that during the design and production process of the aerosol generating device, based on the requirement of effective preheating of the atomized medium and the set preheating temperature curve and other factors, a predetermined total preheating energy is determined and stored for the aerosol generating device in advance, and the predetermined total preheating energy represents the total energy that the aerosol generating device should output according to the ideal preheating process (i.e., executing the preheating mode based on the preheating temperature curve). Specifically, the predetermined total preheating energy can be determined by theoretical calculation, a large number of experimental tests, etc., and is solidified in the storage unit of the aerosol generating device (such as a specific storage area of ​​the chip) so that it can be obtained at any time during the preheating control process and used for comparison and judgment.

[0096] After calculating the current preheating total energy E_total and obtaining the predetermined preheating total energy E_target, the current preheating total energy E_total and the predetermined preheating total energy E_target can be compared, and based on the comparison result of the current preheating total energy E_total and the predetermined preheating total energy E_target, it is determined whether to control the aerosol generating device to run the preheating mode based on the second set temperature. This can more scientifically and accurately determine when the aerosol generating device switches from the first set temperature to the second set temperature during the preheating process, thereby optimizing the preheating effect and improving the user experience.

[0097] For a possible implementation, please refer to Figure 3 As shown, Figure 3 : is a flow chart of an optional preheating control method of an aerosol generating device provided in an embodiment of the present application, which determines whether to control the aerosol generating device to run a preheating mode based on a second set temperature based on a comparison result of the current preheating total energy and the predetermined preheating total energy, including:

[0098] S301: If the comparison result indicates that the current preheating total energy is greater than or equal to the predetermined preheating total energy, it is determined to control the aerosol generating device to operate in a preheating mode based on a second set temperature.

[0099] S302: If the comparison result indicates that the current preheating total energy is less than the predetermined preheating total energy, continue to control the aerosol generating device to run the preheating mode based on the first set temperature until the comparison result indicates that the current preheating total energy is greater than or equal to the predetermined preheating total energy.

[0100] Still continuing with the above example, based on the comparison result of the current preheating total energy and the predetermined preheating total energy, the following two cases are discussed:

[0101] Case 1: The current total preheating energy E_total is greater than or equal to the predetermined total preheating energy E_target, which means that from the perspective of output energy, the aerosol generating device has output enough energy or has reached or even exceeded the total amount of energy that should be output according to the ideal preheating process. At this time, it can be determined that the aerosol generating device is controlled to run the preheating mode based on the second set temperature. In other words, the control component of the aerosol generating device sends an instruction to the heating component to switch the heating temperature from the current first set temperature to the second set temperature, and continue the preheating operation to complete the remaining preheating time.

[0102] Case 2: The current preheating total energy E_total is less than the predetermined preheating total energy E_target, indicating that the energy currently output by the aerosol generating device has not yet reached the total amount required by the ideal preheating process. In this case, it is necessary to continue to control the aerosol generating device to run the preheating mode based on the first set temperature, so that the aerosol generating device continues to heat at a higher temperature. At the same time, in this process, the relevant monitoring and calculation mechanisms inside the aerosol generating device will continue to operate. Specifically, the aerosol generating device continues to recalculate the cumulative output energy, the expected output energy and other related parameters according to the previously described process (because as time goes by, the cumulative output energy will continue to increase, and the remaining preheating time will continue to decrease, thereby affecting the calculation of the expected output energy), and will again compare the current preheating total energy with the predetermined preheating total temperature. This cycle will be repeated until a comparison result shows that the current preheating total energy is greater than or equal to the predetermined preheating total energy. At this time, the heating temperature will be switched to the second set temperature according to the previous process to continue the preheating operation.

[0103] Through the above-mentioned dynamic control mechanism based on the energy comparison results, the aerosol generating device can adapt to different initial conditions (such as the initial temperature when the aerosol generating device is started, etc.) more accurately, and effectively avoid problems such as insufficient preheating of the atomizing medium or excessive volatilization of components due to insufficient or excessive energy supply, thereby providing users with a more stable usage experience.

[0104] For a possible implementation, please refer to Figure 4 As shown, Figure 4 is a flow chart of an optional preheating control method of an aerosol generating device provided in an embodiment of the present application. After determining to control the aerosol generating device to run a preheating mode based on a second set temperature, the method further includes:

[0105] S401 : Determine the current remaining preheating time of the aerosol generating device based on the total preheating time and the current accumulated preheating time of the aerosol generating device.

[0106] S402, controlling the aerosol generating device to run a preheating mode based on the second set temperature and the current remaining preheating time.

[0107] S403, when the current remaining preheating time is reached, controlling the aerosol generating device to end the preheating mode.

[0108] Specifically, the total preheating time is predetermined during the design or preset process of the aerosol generating device, and represents the total amount of time required to complete the entire preheating process under ideal conditions. The current cumulative preheating time of the aerosol generating device is the preheating time that has been continuously recorded by the timing mechanism (such as the timer module) inside the aerosol generating device during the preheating mode based on the first set temperature.

[0109] In the example of this application, after determining to control the aerosol generating device to run the preheating mode based on the second set temperature, it is first necessary to clarify how much preheating time is left at this stage. Specifically, the remaining preheating time of the aerosol generating device when it is currently switched to the second set temperature can be calculated by subtracting the accumulated preheating time of the aerosol generating device from the known total preheating time. For example, the total preheating time is set to 30 seconds, and the current accumulated preheating time is calculated to be 10 seconds, then the remaining preheating time is 30-10=20 seconds.

[0110] After determining the remaining preheating time, the control element of the aerosol generating device controls the aerosol generating device to continue the preheating operation according to the remaining preheating time and the second set temperature. Specifically, the control element sends an instruction to the heating component, instructing the heating component to set the heating temperature to the second set temperature, and continue to maintain this temperature for heating according to the remaining preheating time. In this process, the heating component will heat the atomizing medium, etc. at a stable second set temperature according to the received instruction, so that the substance inside the atomizing medium continues to be activated, volatilized, etc. at this temperature.

[0111] At the same time, the relevant monitoring mechanisms inside the aerosol generating device (such as temperature sensors, energy monitoring modules, etc.) continue to work to ensure that the heating temperature can be stably maintained at the second set temperature, and to monitor in real time whether the remaining preheating time has been reached. If the temperature deviates from the second set temperature during the heating process, the control element can adjust the power and other parameters of the heating component in time; if it is detected that the remaining preheating time is about to expire, corresponding preparations are made to end the preheating mode.

[0112] When heating is continued in the above manner until the current remaining preheating time reaches the preset value, the condition for ending the preheating mode is met. At this time, the control element of the aerosol generating device controls the aerosol generating device to end the preheating mode, for example, stops sending heating instructions to the heating component, turns off the relevant heating circuit, etc., so that the heating component stops heating. Through the above optional implementation method, the aerosol generating device can accurately complete the remaining preheating process after switching to the second set temperature, ensuring that the atomized medium is fully and appropriately preheated, providing a good experience for the user.

[0113] For a possible implementation, please refer to Figure 5 As shown, Figure 5 is a flow chart of an optional preheating control method for an aerosol generating device provided in an embodiment of the present application. After the aerosol generating device ends the preheating mode, or while the aerosol generating device ends the preheating mode ( Figure 5 , the method further comprises:

[0114] S501, controlling the aerosol generating device to output prompt information, where the prompt information is used to remind the user to use the aerosol generating device to perform atomization operation;

[0115] S502 , in response to the user starting to use the aerosol generating device to perform an atomization operation, controlling the aerosol generating device to operate an atomization mode based on a preset temperature curve.

[0116] In the example of the present application, after the control element inside the aerosol generating device detects the signal indicating the end of the preheating mode, it will trigger the output function of the prompt information, and the prompt information can be presented to the user in a variety of ways, for example, the indicator light on the aerosol generating device flashes a specific frequency or color, for example, it turns green or flashes green; or a specific sound prompt is issued through a buzzer built into the aerosol generating device, for example, a short beep or several beeps; or when the aerosol generating device has a display screen, a text prompt can be displayed on the screen, such as "Preheating is complete, atomization can begin", etc. Of course, these prompt methods can be used alone or in combination to ensure that the user can notice the state changes of the aerosol generating device, and avoid the user from performing atomization operations too early or too late without knowing it, thereby ensuring that the user can use the aerosol generating device at the best time to obtain a better atomization effect and taste.

[0117] When the user receives the prompt information and starts to use the aerosol generating device to perform atomization operation, for example, the user puts his mouth close to the mouthpiece and starts to inhale, the aerosol generating device will detect the user's atomization action through the sensor (such as the airflow sensor detects the airflow change). If the user's atomization operation is detected, the control element of the aerosol generating device will respond immediately and control the aerosol generating device to operate the atomization mode based on the preset temperature curve.

[0118] It should be understood that the preset temperature curve is pre-set and stored in the aerosol generating device, and describes the temperature change pattern that the heating component should maintain during the atomization process as time passes or the user's atomization intensity changes. During the operation of the atomization mode, the heating component will heat the atomization medium according to this preset temperature curve, so that the atomization medium evaporates at a suitable temperature to form atomized steam, and the user inhales the atomized steam into the mouth through inhalation, thereby completing the atomization process.

[0119] At the same time, during the operation of the aerosol generating device in the atomization mode, it can also, but is not limited to, continue to monitor various parameters, such as whether the heating temperature meets the curve requirements, whether the battery power is sufficient, the remaining amount of atomization liquid, etc., and make corresponding adjustments or prompts according to changes in the above-mentioned monitoring parameters to ensure the continuous and stable progress of the atomization process.

[0120] In a possible implementation, determining, based on the remaining preheating time and the second set temperature, an estimated output energy of the aerosol generating device in a preheating mode based on the second set temperature includes:

[0121] Calculate the product of the square value of the second set temperature and the remaining preheating time;

[0122] The product is taken as the expected output energy of the aerosol generating device when operating in the preheating mode based on the second set temperature.

[0123] In one example, first, the second set temperature is determined (this temperature value is pre-set and stored in the aerosol generating device, and the unit is usually a temperature unit such as Celsius). Then, the second set temperature is squared. For example, if the second set temperature is T2 (assuming T2 = 200°C), then its square value is T2 2 =200 2 =40000 (the values ​​here are only examples, the actual units depend on the specific energy calculation system, and may need further conversion to correspond to common energy units).

[0124] After obtaining the square value of the second set temperature, multiply the square value by the remaining preheating time. The remaining preheating time is obtained by subtracting the accumulated preheating time at the first set temperature from the total preheating time when it is determined to switch to the second set temperature for preheating (the unit is usually seconds or other time units). Assuming that the remaining preheating time is t2 (for example, t2 = 10 seconds), the expected output energy E2 (the unit may be joules or other energy units, depending on the setting and conversion of the entire energy calculation system) is equal to the square value of the second set temperature multiplied by the remaining preheating time, that is, E2 = T2 2 × t2. According to the above example values, E2 = 40000 × 10 = 400000. It should be noted that the above example values ​​do not constitute a constraint on the present application. In the actual calculation process, the actual value can be accurately calculated according to the actual temperature and time set by the aerosol generating device, and the necessary unit conversion can be performed to obtain the actual value.

[0125] Through the above-mentioned calculation method, the expected output energy of the aerosol generating device when running in the preheating mode based on the second set temperature can be estimated more accurately, and then combined with other calculated energy parameters such as cumulative output energy, it is accurately determined whether to switch to the second set temperature for preheating and subsequent preheating control operations, so as to achieve an optimized preheating effect and a stable user experience.

[0126] 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.
