[0020] This application relates to the field of heating and coordinated control technology for electronic atomizers, and is particularly applicable to integrated electronic atomizers that are equipped with dual independent heating structures and can simultaneously generate two types of aerosols.

[0021] In related technologies, with the widespread application of dual-heat-source composite atomizers, users' requirements for atomization performance and operational safety are increasing. However, the output coordination and matching of the dual heating components in current atomizers are insufficient, resulting in poor aerosol output uniformity during heating and consequently, inconsistent continuous atomization experience. Specifically: First, the atomizing heating power is difficult to adapt to the dynamic changes in solid matrix aerosol release. Throughout operation, the equipment is prone to insufficient output in the early stages, high concentration in the middle stages, and continuous attenuation in the later stages, resulting in inconsistent aerosol output and a poor user experience across different stages. Second, power adjustment only targets the liquid heating side, failing to compensate for heat loss on the solid heating side in a timely manner. After continuous aspiration, the solid matrix temperature continues to drop, and the aerosol concentration differs significantly between adjacent aspirations, leading to noticeable fluctuations in the user experience. Third, during multiple consecutive aspirations in a short period, the temperature and power compensation range accumulates, easily causing overheating of the matrix and prolonged overheating of heating components. This not only accelerates component aging but also poses certain safety risks. Fourth, the power output lacks reasonable boundary control, with the compensated power frequently exceeding the rated operating range of the heating components. Furthermore, there is no limit to the duration of a single aspiration session, and no active power-off measures are available for prolonged continuous aspiration, resulting in a short overall equipment lifespan. Fifth, when the equipment switches between different operating stages, the atomization heating power will jump, which can easily cause a sudden increase or decrease in aerosol output, insufficient suction smoothness, and interfere with the user's continuous use rhythm.

[0022] To address the technical problem of insufficient output coordination and matching of the dual heating components in the aforementioned atomizers, resulting in poor aerosol output uniformity during heating and consequently inconsistent continuous atomization experience, this embodiment provides an example of an electronic atomizer. Please refer to [link / reference]. Figure 1 As shown, Figure 1 This is a schematic diagram of the architecture of an electronic atomizer according to an embodiment of this application. The electronic atomizer may specifically include, but is not limited to, a first heating component 101, a second heating component 102, a memory 103, and a processor 104; the first heating component 101, the second heating component 102, and the memory 103 are all electrically connected to the processor 104; the memory 103 internally stores a computer program that can run on the processor 104, and when the processor 104 loads and executes the computer program, it can implement any of the heating coordination control methods of the electronic atomizer in this application.

[0023] In some embodiments, the electronic atomizer is also equipped with an atomization detection unit, for example, a microphone sensor. The signal output logic of the microphone sensor is as follows: when the electronic atomizer is in an idle state / idle standby state without atomization airflow, it continuously outputs a high-level signal. Once atomization airflow is sensed and atomization action is generated, the output level immediately switches to a low level, thereby feeding back two key trigger signals to the processor: the start signal of atomization action and the end signal of atomization action.

[0024] In this embodiment of the disclosure, the first heating component is specifically a heating structure for heating a solid substrate, such as a heated non-combustible HNB component (hereinafter referred to as HNB heating component), which includes two independently temperature-controllable zones: an upper heating zone and a lower heating zone. It can stably and continuously heat the solid substrate according to a preset temperature curve (specifically a segmented temperature control curve) and supports zoned differential temperature rise compensation.

[0025] In this embodiment of the disclosure, the second heating component is specifically a heating structure for heating a liquid matrix, such as an atomizing heating component. The output power of the second heating component is determined by the real-time reference power. It only outputs heating energy when atomizing airflow / suction airflow is detected. In the standby idle state, it only updates the reference power and does not output heating power.

[0026] In some embodiments, the first heating component is divided into two independent heating zones: an upper heating zone and a lower heating zone. The processor can issue independent heating control commands to the two zones respectively, which can realize asymmetric differential heating compensation between the upper and lower zones. The second heating component is equipped with an independent power output drive circuit, which only outputs heating power when it receives a valid signal of atomization action. In the idle state, the power output drive circuit has no power output, and the internal reference power parameters are only updated by the processor background.

[0027] In this embodiment of the disclosure, the atomizing matrix includes two types of aerosolizable raw materials: a solid matrix and a liquid matrix, which are respectively matched with the first heating component and the second heating component to achieve heating and atomization.

[0028] In some embodiments, the memory can be a non-volatile memory, which can be divided into two main storage areas: a non-volatile storage area and a volatile storage area. The non-volatile storage area is used to permanently store the control parameters of the device, including preset temperature curves, threshold values ​​for switching durations at each stage, threshold values ​​for the number of atomizations at each stage, maximum power threshold, minimum power threshold, temperature compensation duration, and abnormal duration threshold. The volatile storage area is used to temporarily store dynamic operating data during the operation of the electronic atomizer, including the current operating stage identifier, idle time timing variables, atomization time timing variables, real-time reference power, and cumulative number of atomizations. Temporary data in the volatile storage area is automatically cleared after the device is powered off.

[0029] In some embodiments, the processor has two sets of independent software timing logic, corresponding to the idle duration timing variable and the atomization duration timing variable, respectively. The operating conditions of the two types of timing variables are completely mutually exclusive. The idle standby condition only activates the idle duration timing variable, and the atomization condition only activates the atomization duration timing variable. The two sets of duration statistics do not interfere with each other and will not produce numerical superposition deviations.

[0030] In some embodiments, the electronic atomizer is also equipped with a complete support structure, including the device shell of the electronic atomizer, a solid matrix receiving cavity, a liquid matrix storage cavity, an airflow channel connecting the mouthpiece and the atomization detection unit, and a power supply cell for the entire device; the solid matrix receiving cavity is used to place the solid aerosol generation matrix, the liquid matrix storage cavity is used to store the liquid aerosol generation matrix, and the power supply cell continuously provides working power to all electrical components of the processor, the two types of heating components, and the atomization detection unit.

[0031] In some embodiments, the processor serves as the central control unit of the electronic atomizer, undertaking the coordination and instruction issuance of all functional modules of the device. The processor can be selected from any of the following: general-purpose microcontrollers, dedicated control integrated circuits, and field-programmable logic arrays. It can also adopt a multi-processing unit collaborative integration architecture, with adaptive optimization design in terms of signal response delay, real-time computing speed, and static power consumption control.

[0032] In some embodiments, the overall circuit connection of the electronic atomizer may be, but is not limited to, as shown below: the processor is electrically connected to the first heating component drive circuit, the second heating component drive circuit, the atomization detection unit, the memory, and the power supply cell, respectively. The cell's charging and discharging management circuit communicates with the processor. The charging and discharging management circuit is responsible for overcharging, over-discharging, and overcurrent protection of the cell and real-time acquisition of the remaining power.

[0033] In this embodiment, after the electronic atomizer completes the power-on initialization operation, the processor reads all preset control parameters from the non-volatile memory, continuously collects airflow level signals in real time through the atomization detection unit, and synchronously reads the real-time cumulative duration of two sets of timing variables. The processor combines the current operating stage of the electronic atomizer with the corresponding constant temperature zone and exclusive power adjustment strategy, and fully executes the complete set of collaborative control logic, including phased adaptive power control, atomization duration quantification power compensation, dual heat source synchronous zone temperature repair, continuous atomization compensation refresh, automatic power range limiting, ultra-long atomization power failure protection, and phased reference power inheritance. It balances and regulates the total synchronous output of the two types of aerosols, achieving stable output throughout the process, small continuous atomization fluctuations, and safe device operation.

[0034] To address the aforementioned technical problems, this embodiment provides a control method for an electronic atomizer. This method is provided as an example and not a limitation. It can be applied to or operated in electronic devices, such as the electronic atomizer described in the foregoing embodiment. The electronic atomizer is equipped with a first heating component and a second heating component that are independent of each other. The two components correspond to different atomization matrices and work together to generate aerosols.

[0035] Please refer to Figure 2 As shown, Figure 2 The flowchart illustrates the control method of the electronic atomizer of this application, which includes: S201 acquires the current operating stage of the electronic atomizer and monitors the atomization action in real time.

[0036] S202, control the first heating component to heat the atomizing matrix in the electronic atomizer according to the temperature segment corresponding to the current operating stage in the preset temperature curve, and dynamically update the reference power of the second heating component according to the current operating stage.

[0037] S203 responds to the start / stop signal of the atomization action and controls the second heating component to perform heating operations during the atomization process and power compensation operations after the atomization process.

[0038] In some embodiments, after the e-vaporizer completes initialization upon power-on, the processor first identifies the current operating stage of the e-vaporizer. It should be understood that, based on the aerosol release pattern of the atomizing matrix, the entire single-cycle operation of the e-vaporizer can be divided into multiple sequentially connected operating stages. Stage-by-stage control allows the heating output to precisely match the release characteristics of the matrix at different operating times, avoiding the imbalance problem of insufficient output in the early stages and excessive output in the later stages caused by a fixed power output. Simultaneously, the processor monitors the airflow state in the airway in real time through the atomization detection unit, continuously collecting airflow level change signals to identify the start and end signals of the user's inhalation action, ensuring that the heating action is completely synchronized with the user's operation and reducing ineffective heating losses.

[0039] During the operation of the e-cigarette, the processor controls the first heating component to operate continuously according to a preset temperature curve. Based on the temperature range corresponding to the current operating stage, it bakes the solid atomization matrix at a constant target temperature, ensuring uniform heating of the matrix and a stable aerosol release rate. This allows the e-cigarette to provide a continuous and stable output of basic aerosol. Simultaneously, the processor dynamically updates the base power of the second heating component according to the power adjustment strategy matched to the current operating stage. This allows the output capacity of the second heating component to adaptively adjust with the overall operation of the device, dynamically adjusting its contribution ratio in conjunction with the output changes of the first heating component. This achieves dynamic synergistic matching of the two types of aerosol output, maintaining a balanced and stable total aerosol output during the overall heating process.

[0040] In some embodiments, when the processor detects a signal to initiate atomization, for example, when the atomization detection unit switches from a high level to a low level, it immediately controls the second heating component to output heating energy at the current real-time reference power to heat the liquid atomization matrix and generate an aerosol, responding to the user's inhalation needs. When the processor detects a signal to end atomization, for example, when the atomization detection unit returns from a low level to a high level, it performs a compensatory boost on the reference power of the second heating component based on the duration of this inhalation, making up for the heat loss carried away by the airflow during inhalation and avoiding the gradual attenuation of output intensity caused by continuous heat loss during continuous inhalation.

[0041] In this embodiment, the base power after compensation will be used as the latest base power for dynamic power updates during subsequent idle periods in the current operating phase, ensuring stable output intensity for the next pumping and improving the consistency of taste during continuous pumping.

[0042] This embodiment presents the basic logic for dual-heating collaborative control. Subsequent refined control schemes, such as phased power trend adjustment, duration statistics of dual independent timing variables, zoned temperature compensation for the first heating element, power range limiting constraints, and abnormal protection for ultra-long inhalation, are all further extended and implemented based on this basic control logic. Through a layered and progressive control mechanism, it achieves balanced aerosol output, strong consistency in continuous inhalation, and high energy utilization efficiency within the operating cycle, effectively improving the technical problems of low aerosol output matching with user operation and large fluctuations before and after inhalation in traditional dual-heating element electronic atomizers.

[0043] In some embodiments, please refer to Figure 3 As shown, Figure 3 The flowchart illustrates the control method of the electronic atomizer of this application. Responding to the start / stop signal of the atomization action, the method controls the second heating component to perform heating operations during the atomization process and power compensation operations after the atomization process, including: S301, in response to the start signal of the atomization action, controls the second heating component to heat the atomization matrix at the current reference power; S302, in response to the end signal of the atomization action, performs power compensation on the reference power of the second heating component according to the duration of the atomization action, and uses the compensated reference power as the latest reference power for subsequent dynamic updates within the current operating phase.

[0044] In this embodiment, the control scheme for the second heating component is further refined, and the synergy between real-time response and heat compensation is achieved through start-stop step control.

[0045] When the processor receives the atomization activation signal, it directly uses the currently updated reference power as the output basis, controlling the second heating component to immediately enter the heating operation state, heating the liquid atomization matrix to generate aerosol. This response method, which directly calls the real-time reference power, can minimize the heating response delay, ensuring a stable aerosol output from the initial stage of suction. Furthermore, the output power matches the control strategy of the current operating stage, avoiding output anomalies caused by power jumps.

[0046] When the processor receives the signal indicating the end of the atomization process, it can calculate the corresponding power compensation based on the duration of the atomization process and compensate for the base power of the second heating component. Since the airflow continuously carries away heat from the heating chamber and substrate during the suction process, the longer the suction duration, the greater the total heat loss. Therefore, the compensation amount is positively correlated with the suction duration, accurately matching the heat loss caused by different suction depths. Compared to a fixed compensation amount, this approach better reflects actual operating conditions and effectively avoids the problems of output attenuation after a long suction and overcompensation after a short suction.

[0047] It should be understood that the baseline power after compensation will serve as the latest baseline power for dynamic updates of power during subsequent idle periods within the current operating phase. This ensures that power adjustment during idle periods is always based on the latest thermal state, guaranteeing the continuity of power adjustment within the phase, resulting in smaller output differences between two adjacent suction cycles and better consistency for continuous use.

[0048] In some embodiments, the current operating stage is obtained by dividing the single operating cycle of the electronic atomizer based on the aerosol release pattern of the atomizing matrix. The current operating stage includes: a preheating stage, a first atomization stage, and a second atomization stage, with the second atomization stage following the first atomization stage.

[0049] In some embodiments, the reference power of the second heating component is dynamically updated based on the current operating phase, including: During the preheating and first atomization stages, the base power of the second heating component is controlled to decrease gradually, based on the cumulative idle time during the current operation stage. During the second atomization stage, the reference power of the second heating component is controlled to increase gradually, based on the cumulative idle time during the current operation stage.

[0050] In this embodiment, based on the aerosol release pattern of the atomizing matrix, the single complete operation cycle of the electronic atomizer is divided into stages. These stages, arranged chronologically, are a preheating stage, a first atomization stage, and a second atomization stage, with the second atomization stage following the first. This staged control allows the output capacity of the second heating component to match the aerosol release level of the first heating component at different times, dynamically adjusting the aerosol contribution ratio of the two matrix types. This maintains a balanced and stable total aerosol output throughout the entire process, avoiding the technical problem of excessive differences in aerosol output before and after the fixed power mode.

[0051] During the preheating and first atomization phases, the processor uses the accumulated idle time during the current operating phase as a calculation benchmark to control the reference power P1 of the second heating component to decrease linearly with the increase of idle time t.

[0052] In the initial preheating stage, the first heating component has not yet fully heated the solid matrix, resulting in a low aerosol release rate. The second heating component uses a higher initial reference power to compensate for the insufficient total aerosol output in the early stage. As the idle running time continues to increase, the first heating component continuously bakes the solid matrix, gradually heating it sufficiently, and the aerosol release rate steadily increases. Correspondingly, the output reference power of the second heating component is gradually reduced to avoid an excessively high total amount of both types of aerosols combined, ensuring that the output concentration remains within a reasonable range. After entering the first atomization stage, the aerosol release from the solid matrix reaches its peak. The reference power of the second heating component continues to decrease, gradually reducing the output proportion of the liquid matrix, making the aerosol from the solid matrix the main output source, which aligns with the objective characteristics of the natural release of the atomization matrix.

[0053] Specifically, during the preheating phase, P1 = P0 - k1 t, where the initial value P0 is the maximum power Pmax at the start of the preheating phase, and k1 is the power change rate coefficient in the idle state, specifically a preset fixed decreasing coefficient, with units of power / time.

[0054] In the first atomization stage, P1 = P0 - k3 t3, the release of solid matrix aerosol reaches its peak. In the idle state, the reference power of the second heating component continues to decrease linearly with the idle time t, and the deceleration rate is k3. At the same time, a power lower limit constraint is set, and the reference power is not less than Pmin to avoid the power being too low to generate effective aerosol.

[0055] After entering the second atomization stage, the solid matrix undergoes prolonged baking, gradually consuming its atomizable components and causing a natural decline in aerosol release capacity. At this point, the processor, using the cumulative idle time within the current operating phase as a benchmark, controls the base power of the second heating component to gradually increase with the idle time t. By gradually increasing the heating power of the liquid matrix, the total output shortfall caused by the solid matrix's release decline is compensated, slowing down the rate of output decrease in the later stages. This ensures that the overall aerosol output remains relatively stable throughout the entire process, effectively addressing the technical issues of insufficient aerosol output and a significant decrease in user experience in the later stages.

[0056] Specifically, in the idle state, the reference power of the second heating component increases linearly with the idle duration t, P0 = P1 + k2 t. After the suction action is detected to be over, based on the duration t of this suction, the output ratio of liquid heating is gradually increased to make up for the total aerosol output gap of the whole machine. The current reference power P1 is compensated and increased according to the compensation coefficient k2 to obtain a new starting reference power P0, which is used as the initial value for the power reduction in the next idle cycle.

[0057] It should be noted that this phased differentiated power adjustment logic can work in conjunction with an independent idle duration timing variable mechanism. The idle duration timing variable accurately counts the idle running time in each operating phase, providing an accurate time basis for dynamic power updates.

[0058] In some embodiments, in response to the current operating phase meeting a preset phase switching condition, the electronic atomizer is controlled to switch to the next operating phase, and the initial reference power of the second heating component in the next operating phase is determined based on the reference power of the second heating component at the end of the current operating phase.

[0059] In this embodiment, the processor verifies the operating parameters of the current operating stage in real time to determine whether the preset stage switching conditions are met. Once the conditions are met, the processor controls the electronic atomizer to smoothly switch to the next operating stage. The switching conditions for each stage are matched with the stage's own control objectives. The preheating stage uses the cumulative running time as the switching criterion, while the first and second atomization stages combine the cumulative number of puffs and the cumulative running time for dual-dimensional judgment. Meeting either condition can trigger a stage jump, adapting to user scenarios with different usage frequencies.

[0060] During phase switching, the initial reference power of the second heating component in the next operating phase is directly adopted from the reference power value at the end of the current operating phase. This value is the final effective value after power compensation and range limiting at the end of the current phase, and does not need to be reset to a fixed initial value when switching phases. This power inheritance design can avoid power jumps during phase switching, prevent abrupt fluctuations in aerosol output, and make the transition between different phases smoother and more natural. Users can hardly perceive the phase switching nodes during continuous use, improving the continuity of the suction experience.

[0061] The inherited initial reference power will serve as the starting point for dynamic power adjustment in the next stage, matching the power change trend corresponding to the next stage. For example, when switching from the preheating stage to the first atomization stage, the reference power that gradually decreased at the end of the preheating period will be inherited and adjusted along the decreasing trend, which can match the law of the continuous increase in the release of solid matrix aerosols; when switching from the first atomization stage to the second atomization stage, the low reference power at the end of the first stage will be inherited and then gradually increased along the increasing trend, which matches the characteristic of the gradual decay of the release capacity of solid matrix.

[0062] In some embodiments, the electronic atomizer maintains independent idle time timing variables and atomization time timing variables, such as Figure 4 As shown, the method also includes: S401, In the idle state, the idle running time is continuously accumulated through the idle duration timer variable during the current running phase, and the idle state indicator does not detect atomization action; S402, in response to the start signal of the atomization action, clears and resets the idle duration timer variable, starts the atomization duration timer variable, and accumulates the duration of this atomization action; S403, in response to the end signal of the atomization action, clears and resets the atomization duration timer variable to zero, restarts the idle duration timer variable and continues to accumulate the idle running time.

[0063] In this embodiment, the processor of the electronic atomizer can maintain two sets of independent timing variables: idle time timing variable and atomization time timing variable. The two types of variables correspond to different operating conditions, and the timing logic does not interfere with each other. It can accurately distinguish the duration data of the two states of idle standby and atomization inhalation, and provide an accurate time reference for dynamic power adjustment and compensation calculation.

[0064] It should be understood that the idle state refers to the standby condition where no atomization action is detected. In this state, the idle duration timer variable continuously accumulates during the current operating phase. Based on this accumulated duration, the processor dynamically updates the reference power of the second heating component according to the power change trend corresponding to the current phase. Independent idle timing eliminates interference from suction action, ensuring that the accumulated idle duration accurately corresponds to the standby heating time dimension. This allows the power adjustment slope to strictly match the aerosol release pattern of the matrix, avoiding power adjustment inaccuracies caused by duration statistical deviations.

[0065] Upon receiving the start signal for atomization, the processor immediately resets the idle timer variable to zero and simultaneously starts the atomization duration timer variable to accumulate the duration of the current atomization action. The design of resetting the idle timer ensures that after each vaping session, power adjustment restarts from zero to re-accumulate the idle time, guaranteeing that power updates during each standby period are based on a complete idle cycle, conforming to the objective law of natural changes in matrix heat. The atomization duration timer variable specifically tracks the duration of a single vaping session; its data is unaffected by the accumulation of idle time, accurately reflecting the vaping depth and total heat loss, providing a reliable quantitative basis for subsequent power compensation calculations.

[0066] When the processor receives a signal indicating the end of the atomization process, it resets the atomization duration timer variable to zero and restarts the idle duration timer variable to continue accumulating the idle runtime of the current phase. Resetting the atomization timer prevents the duration of multiple vape cycles from accumulating, ensuring that the compensation for each vape cycle only corresponds to the heat loss generated during that vape cycle, preventing the compensation amount from accumulating with the number of vape cycles. Restarting the idle timer allows the power adjustment to return to the normal standby update logic, continuing operation with the latest reference power after vape compensation, maintaining the consistency and smoothness of power adjustment within the phase.

[0067] It should be noted that the division of labor between the two sets of independent timing variables, in conjunction with mechanisms such as phased power adjustment, power compensation after pumping, and continuous pumping compensation refresh, can ensure both the accuracy of dynamic power updates during idle periods and the precision of calculating the compensation amount for a single pumping operation.

[0068] In some embodiments, during the first atomization stage and the second atomization stage, in response to the end signal of the atomization action, while power compensation is performed on the reference power of the second heating component based on the duration of the atomization action, temperature compensation control is simultaneously performed on the first heating component.

[0069] In this embodiment, the dual-component synchronous compensation mechanism is limited to triggering and executing only during the first and second atomization stages. During the preheating stage, the solid matrix is ​​still in the process of continuous heating, and the aerosol release demand is low. The heat loss from a single suction has a limited impact on the overall output. The output gap can be made up by the power compensation of the second heating component alone, without the need to activate the temperature compensation of the first heating component. This reduces unnecessary heating actions, lowers energy loss during the preheating stage, and also prevents the matrix from being overheated in advance, which could affect the subsequent release performance.

[0070] After entering the first and second atomization stages, the solid matrix is ​​in the core usage range of stable release or gradual decay, and users have a higher suction frequency and stricter requirements for output consistency. At this time, the heat carried away by the suction airflow not only affects the heating efficiency of the liquid matrix, but also causes temperature fluctuations in the solid matrix, directly affecting the subsequent release amount and uniformity of aerosols. Therefore, a control logic with dual-component synchronous compensation is adopted.

[0071] When the processor detects the end signal of the atomization process, it calculates the power compensation amount of the second heating component and updates the baseline power based on the duration of this suction, while simultaneously sending a temperature compensation command to the first heating component to initiate short-term zoned temperature rise compensation. Both types of compensation are triggered synchronously based on the duration data of the same suction session, simultaneously compensating for heat loss on both the liquid and solid heating sides. Compared to solutions that only compensate for a single heating component, the heat recovery is more comprehensive, ensuring that the output intensity of both types of aerosols remains stable during the next suction session, preventing an imbalance where one side is sufficiently strong while the other weakens.

[0072] In some embodiments, the method further includes: Within the preset temperature compensation duration, the upper and lower heating zones of the first heating component are controlled to implement asymmetric temperature rise compensation; wherein the temperature rise increment of the upper heating zone is higher than that of the lower heating zone.

[0073] In this embodiment, the temperature compensation execution logic of the first heating component is further refined. After the atomization action ends, a short-term temperature rise compensation is initiated simultaneously, and the compensation process continues within a preset temperature compensation duration. The temperature compensation duration is a pre-calibrated fixed parameter and is pre-stored in the non-volatile memory of the electronic atomizer. The value of the temperature compensation duration is determined by combining the heat capacity of the solid matrix, the heating rate of the heating component, and the user's habitual inhalation interval, such as 4-6 seconds, for example 5 seconds. This ensures that the temperature of the atomized matrix fully recovers to the target level while avoiding unnecessary energy loss and matrix overheating caused by an excessively long compensation duration.

[0074] During the compensation process, the processor controls the upper and lower heating zones of the first heating component to perform asymmetric temperature rise compensation. The temperature rise increment of the upper heating zone is higher than that of the lower heating zone; for example, if the upper heating zone rises by 35°C, the lower heating zone rises by 20°C. Since the suction airflow passes through the air channel at the top of the atomizer, the heat loss rate in the upper region is significantly higher than that in the lower matrix-containing region. After a single suction, the temperature drop of the upper matrix is ​​greater. Therefore, matching a higher temperature rise increment can accurately compensate for the heat gap in the upper region, allowing the temperature of both the upper and lower regions of the solid matrix to rise to the target level simultaneously, avoiding insufficient sol release in the next breath due to a lag in upper temperature recovery. Compared to a scheme that uniformly heats both the upper and lower regions, asymmetric compensation ensures efficient temperature recovery without over-baking the lower matrix, effectively balancing suction consistency and matrix heating uniformity.

[0075] The partition temperature rise compensation mechanism is triggered synchronously with the power compensation of the second heating component. The two work together to compensate for the system heat carried away by the suction airflow. At the same time, in conjunction with the subsequent continuous suction compensation refresh logic, the temperature rise increment is not repeatedly added during multiple suctions in a short period of time. Instead, the timing start of the temperature compensation maintenance duration is reset. This avoids the risk of matrix overheating caused by continuous temperature rise from the control level, and ensures the safety of equipment operation while improving the stability of continuous suction.

[0076] In some embodiments, such as Figure 5 As shown, the method also includes: S501, if multiple atomization actions are detected continuously within the temperature compensation maintenance time, power compensation for the reference power of the second heating component is stopped, and temperature compensation control is performed on the first heating component. S502, starting from the end time of the last atomization action, recalculate the temperature compensation duration; S503, during the recalculated temperature compensation maintenance period, controls the upper heating zone and lower heating zone of the first heating component to implement asymmetric temperature rise compensation.

[0077] In this embodiment, a dedicated compensation refresh logic is set up for the special working condition of users continuously drawing in multiple times during the temperature compensation process. This avoids the problem of heating temperature and output power exceeding the standard caused by the continuous accumulation of compensation amount in a short period of time, and takes into account the output stability and operational safety of continuous drawing in.

[0078] During operation before the temperature compensation duration expires, if the processor detects multiple atomization actions consecutively, it will no longer add additional power compensation to the base power of the second heating component, nor will it accumulate the temperature compensation of the first heating component. Since the suction airflow itself carries away heat from the system, if an additional full compensation is added with each suction, multiple suctions in a short period will cause the compensation to accumulate continuously, gradually exceeding the reasonable range for heating temperature and output power. This can lead to problems such as excessive substrate heating and high-temperature aging of components. Eliminating the amplitude superposition constrains the compensation upper limit from a control logic perspective, stabilizing the overall heating condition within a safe and reasonable range.

[0079] At this point, the processor will use the end time of the last atomization action as a new starting point to recalculate a complete temperature compensation maintenance duration. During continuous vaping, the system's heat loss reaches the peak of that round of vaping at the end of the last vaping. Starting the full-duration compensation from this point ensures that the system's heat is fully replenished, preventing insufficient output intensity in subsequent vaping due to premature termination of the compensation duration, and ensuring a sufficient temperature recovery period after each vaping round. Within the recalculated temperature compensation maintenance duration, the first heating component continues to perform asymmetrical temperature rise compensation between the upper and lower heating zones according to the established rules, maintaining balanced heat recovery in both regions and ensuring uniform heating of the atomization matrix and consistency in aerosol release.

[0080] In some embodiments, the method further includes: After the temperature compensation duration expires, the heating temperature of the first heating component is controlled to drop back to the target temperature value corresponding to the preset temperature curve at the current moment.

[0081] In some embodiments, temperature compensation is not a continuous long-term operation. When the duration of a single temperature compensation is fully completed, the processor cancels the temperature compensation command and controls the heating temperature of the first heating component to smoothly drop back to the standard target temperature value corresponding to the preset temperature curve at the current moment, returning to the normal segmented constant temperature heating logic.

[0082] Since the preset temperature curve itself is a dynamic temperature control benchmark set in stages based on the matrix release characteristics, different target temperatures correspond to different times. The fallback process is based on the target value of the curve at the current time, which can ensure that the heating state after compensation is completed is seamlessly connected with the normal temperature control rhythm of the whole machine, avoid temperature jumps, and reduce interference with the stability of aerosol release.

[0083] This automatic temperature drop-off design after compensation serves two purposes: firstly, it quickly replenishes the heat gap shortly after suction, ensuring the output intensity of the next suction cycle; secondly, it prevents the first heating component from being in an over-temperature compensation state for an extended period, thus preventing premature depletion of effective components, odor, or abnormal release due to continuous over-baking of the solid matrix. It also reduces energy loss from ineffective heating, alleviates the long-term high-temperature load on heating components, and extends the overall lifespan of the device. This drop-off mechanism works in conjunction with the continuous suction compensation refresh logic. If continuous suction occurs within the compensation cycle, the drop-off point is delayed until the complete compensation duration corresponding to the last suction cycle has ended before the drop-off operation is performed. This ensures the continuity of temperature compensation in continuous suction scenarios and guarantees a return to the standard temperature control benchmark after compensation, achieving an orderly switch between dynamic compensation and steady-state temperature control.

[0084] In some embodiments, the method further includes: the switching condition for the preheating phase is that the cumulative preheating runtime reaches a preset preheating duration; The switching condition for the first atomization stage is that the cumulative number of atomization ports reaches the first preset number of ports threshold, or the cumulative running time reaches the first preset duration threshold. The termination condition for the second atomization stage is that the cumulative number of atomization ports reaches the second preset number of ports threshold, or the cumulative running time reaches the second preset duration threshold.

[0085] In some embodiments, the switching and termination conditions for each operating stage are fixed parameters that are pre-calibrated and stored in non-volatile memory. Different operating stages are matched with different judgment dimensions, which correspond one-to-one with the control targets of each operating stage, ensuring that the timing of stage jumps matches the change nodes of aerosol release from the atomizing matrix.

[0086] The switching condition for the preheating stage is that the cumulative preheating time reaches the preset preheating duration, such as 20-30 seconds, for example, 25 seconds. The purpose of the preheating stage is to gradually raise the temperature of the solid matrix to a base temperature at which aerosols can be stably released. Its heating process is only related to the continuous heating time and is not affected by the user's suction frequency. Therefore, using a single cumulative time as the criterion ensures that the matrix is ​​heated sufficiently and evenly when entering the next stage, and that the aerosol release capacity reaches a stable state, avoiding the technical problem of weak aerosol output in the early stage due to insufficient preheating.

[0087] The switching conditions for the first atomization stage adopt a dual-dimensional judgment rule: either the cumulative number of atomization puffs reaches a first preset puff threshold (e.g., 8-10 puffs), or the cumulative runtime reaches a first preset runtime threshold (e.g., 120-180s, for example, 150s). Meeting either condition will trigger the stage switching. The first atomization stage corresponds to the peak range of solid matrix aerosol release. The degree of consumption of effective matrix components is directly related to the number of puffs, as each puff will remove some aerosol and heat, accelerating component consumption, and is also related to the natural decay caused by continuous baking. The dual threshold judgment can adapt to users with different usage habits. In high-frequency puffing scenarios, the switching is triggered by the number of puffs, and in low-frequency intermittent use scenarios, the switching is triggered by the duration, ensuring that the stage jump timing matches the actual degree of matrix consumption, and preventing problems such as entering the later stage prematurely leading to excessive output or entering the later stage lately leading to excessive decay.

[0088] The termination condition for the second atomization stage also adopts a dual threshold rule of cumulative atomization count and cumulative running time. When the cumulative atomization count reaches the second preset count threshold (e.g., 4 counts) or the cumulative running time reaches the second preset duration threshold (e.g., 60-100s, such as 80s), the single running cycle is determined to be over, and the entire machine stops all heating output. The dual-dimensional termination determination can avoid problems such as dry burning and odor caused by continuing to bake after the effective components of the atomization matrix are exhausted. At the same time, it takes into account the rationality of termination under different usage rhythms, ensuring the consistency of usage safety and final experience.

[0089] In some embodiments, both the reference power of the second heating component and the compensated reference power are limited to a preset power range; the upper limit of the preset power range is a maximum power threshold, and the lower limit of the preset power range is a minimum power threshold; the method further includes: If the compensated reference power is higher than the maximum power threshold, then the compensated reference power will be adjusted to the maximum power threshold. If the compensated reference power is lower than the minimum power threshold, the compensated reference power will be adjusted to the minimum power threshold.

[0090] In some embodiments, the electronic atomizer is pre-set with a preset power range to constrain the reference power of the second heating component. Whether it is the original reference power during dynamic updates or the reference power obtained after compensation calculations after vaping, its value is limited to this preset power range. The preset power range is bounded by an upper maximum power threshold and a lower minimum power threshold. Both thresholds are pre-calibrated and stored based on the rated operating parameters of the heating element and the atomization characteristics of the liquid matrix, defining a reasonable operating range from both hardware safety and output effectiveness perspectives.

[0091] Among them, the maximum power threshold Pmax corresponds to the highest power limit that the heating element can work stably for a long time, which can avoid the heating element from overheating and burning due to excessive power, and the liquid matrix from deteriorating at high temperature and producing undesirable releases; the minimum power threshold Pmin corresponds to the minimum power requirement that can stably generate aerosol, which prevents the reference power from being too low, resulting in insufficient heating and failure to generate effective aerosol, thus ensuring basic output performance.

[0092] Once the compensation calculation is complete, if the obtained reference power value is higher than the maximum power threshold, the processor will directly adjust it to the maximum power threshold; if the compensated reference power value is lower than the minimum power threshold, the processor will adjust it to the minimum power threshold. This upper and lower limit clamping method ensures that no matter how large the amplitude of the staged power adjustment or how high the rise of the suction compensation, the final effective reference power is always within a safe and effective range, and extreme operating conditions will not occur.

[0093] It should be noted that this power limiting mechanism works seamlessly with the logic of phased dynamic power adjustment, power compensation after vaping, and continuous vaping compensation refresh. It takes effect at every power change node, including power reduction during the preheating phase, power increase during the second atomization phase, and compensation boost at the end of vaping, thus constraining the fluctuation range of the baseline power. Furthermore, it can work with the ultra-long vaping anomaly protection mechanism to form a dual safety protection for the second heating component, limiting heating conditions from both power amplitude and duration dimensions, further improving the reliability and safety of the entire device. Through standardized interval limiting design, it ensures the stability of output performance under different usage scenarios while effectively avoiding the risk of failure caused by hardware exceeding specifications, improving the long-term consistency and durability of the atomizer product.

[0094] In some embodiments, if the duration of a single atomization action exceeds a preset abnormal duration threshold, the second heating component is controlled to stop outputting heating power until the end signal of this atomization action is received.

[0095] In this embodiment, an abnormal suction duration protection logic is added. A preset abnormal duration threshold is stored in the memory in advance. This threshold can be calibrated in combination with the heat resistance limit of the heating element and the normal atomization consumption rate of the liquid matrix, such as 6-10s, for example 7s, to identify dangerous working conditions of long-term no-load dry suction.

[0096] The processor continuously compares the duration of each atomization action with an abnormal duration threshold by tracking the duration in real time. Once the duration of a single atomization action exceeds the threshold, a cut-off command is immediately issued, controlling the second heating component to terminate all heating power output. The power cut-off state will remain until the processor detects the atomization action end signal and determines that the current vaping has completely ended, at which point the restriction will be lifted and normal power regulation logic will be restored.

[0097] It is understandable that prolonged continuous suction can lead to the liquid matrix supply not keeping up with the heating rate, causing the heating element to dry-burn without a medium. This will not only accelerate the aging of components, but also generate abnormal aerosols. This protection logic can interrupt dangerous heating conditions in time and avoid safety hazards from the source.

[0098] In addition, it should be noted that this abnormal protection mechanism and the baseline power range limiting mechanism form a dual power safety control. The former controls the heating duration, and the latter controls the output power amplitude. The two work together to constrain the working conditions of the second heating component and improve the device operation stability and safety of the electronic atomizer.

[0099] To facilitate understanding of the control method for the electronic atomizer provided in the embodiments of this application, the following specific embodiments are provided for explanation, so that those skilled in the art can understand the control method in this embodiment: Combining the aforementioned staged power regulation, dual-component synchronous compensation, and stage power inheritance control logic, the electronic atomizer operates in the following sequence during a single complete working cycle: preheating stage, first atomization stage, and second atomization stage. The specific execution process of each stage is as follows: The preheating phase is the initial operating phase after the device is powered on. The device automatically enters this phase after hardware initialization and parameter loading. The processor controls the first heating component to match the preheating section of the preset temperature curve, continuously baking the solid substrate at a constant target temperature. In idle standby mode, the idle duration timer continuously accumulates the idle running time of the current phase, and the base power of the second heating component gradually decreases as the idle time increases. Each time an atomization action is detected to have ended, the processor calculates the corresponding power compensation based on the duration of this suction, compensates and increases the base power, and simultaneously performs power upper and lower limit calibration to ensure that the final effective power always remains within the preset safety range. When the accumulated idle running time in the preheating phase reaches the preset preheating time, the device automatically switches to the first atomization phase. The initial base power of the second heating component in the next phase directly inherits the base power value after limiting at the end of the preheating phase, ensuring a smooth and abrupt output during the phase transition.

[0100] After entering the first atomization stage, the device uses the baseline power at the end of the previous stage as the initial value and continues to dynamically update the baseline power of the second heating component along a decreasing trend. This stage corresponds to the peak range of solid matrix aerosol release, where the user's inhalation frequency is higher. Therefore, after inhalation, a dual-component synchronous compensation mechanism is activated: while the processor performs power compensation for the second heating component, it simultaneously controls the first heating component to start upper and lower partition asymmetric temperature rise compensation. The compensation process continues within the preset temperature compensation maintenance time.

[0101] If multiple atomization actions are detected consecutively within the temperature compensation duration, no additional compensation will be added. Instead, the complete compensation duration will be recalculated from the end of the last suction, thus logically constraining the heating conditions and preventing the temperature and power from continuously exceeding the limits.

[0102] If the cumulative number of atomized ports reaches the first preset port number threshold or the cumulative running time reaches the first preset duration threshold during the first atomization stage, the entire device will be switched to the second atomization stage, and the reference power at the end of the current stage will be used as the initial value for the next stage.

[0103] The second atomization stage starts operating from the baseline power of the first atomization stage. During this stage, the effective components of the solid matrix are gradually consumed after continuous baking, and the aerosol release capacity naturally decreases. Therefore, the baseline power of the second heating component gradually increases with the idle time, supplementing the overall aerosol output by increasing the output proportion of the liquid matrix and delaying the later output decay. After each atomization cycle, the power compensation of the second heating component and the zoned temperature rise repair of the first heating component are simultaneously performed to maintain output stability during continuous suction.

[0104] If the cumulative number of atomization ports reaches the second preset port number threshold or the cumulative running time reaches the second preset time threshold during the second atomization stage, the single running cycle is determined to be terminated, the processor cuts off all heating outputs of the first heating component and the second heating component, and ends the complete workflow.

[0105] The control scheme for the electronic atomizer provided in this application has significant technical improvements over the existing heating control scheme for dual-heat-source composite electronic atomizers in terms of output stability, safety of use, and adaptability to different scenarios. The specific advantages are as follows: First, the operation phases are divided according to the objective laws of matrix aerosol release, and different power change trends are matched to different phases. This effectively solves the imbalance problems of insufficient aerosol output in the early stage of operation, excessively high concentration in the middle stage, and release attenuation in the later stage, ensuring that the aerosol output is balanced and stable during the whole machine heating process and eliminating the gap in user experience at different times.

[0106] Secondly, after a single suction cycle, the power of the second heating component is increased and the temperature of the first heating component is restored simultaneously. This can simultaneously compensate for the heat loss of the airflow on both the liquid and solid heating sides, significantly reduce the aerosol concentration fluctuation between two adjacent suction cycles, and significantly improve the output consistency for continuous use.

[0107] Third, for high-frequency continuous suction scenarios, the rule of superimposing multiple rounds of compensation amplitude is cancelled, and only the compensation timing start point is reset. From the control logic level, the risk of matrix overheating and deterioration and long-term over-temperature operation of heating components is avoided, thereby reducing the probability of equipment failure and improving the overall safety level of the machine.

[0108] Fourth, by automatically limiting the output amplitude through the upper and lower limits of the reference power, and by forcibly cutting off the heating time through ultra-long suction, the two work together to stably limit the heating condition of the whole machine within the rated safety range of the components, effectively avoiding safety hazards such as dry burning and over-power, and extending the service life of the product.

[0109] Fifth, when switching between stages, the baseline power at the end of the previous stage is used as the initial value to avoid abrupt fluctuations in aerosol output, ensure smooth continuous suction, and improve the overall user experience.

[0110] Sixth, by using independent idle time and atomization time variables to separately calculate standby time and single vaping time, the corresponding compensation range can be dynamically matched according to the user's vaping intensity, adapting to the usage habits of different users and improving the scene adaptability of electronic atomizers.

[0111] It should be understood that the descriptions of each step and structure in the above embodiments are only preferred implementations of this application. The step numbers do not represent a fixed execution order. Each execution process is determined by the real-time operating conditions and trigger signals of the electronic atomizer. 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 this application. Those skilled in the art can make conventional equivalent substitutions and simple parameter adjustments without departing from the core collaborative control concept of this application, all of which fall within the protection scope of this application.

[0122] In some embodiments, after the temperature compensation duration expires, the heating temperature of the first heating component is controlled to drop back to the target temperature value corresponding to the preset temperature curve at the current moment.
