Description

Technical Field

[0002] Atomizing devices are a type of equipment that heats oil or liquid media to form an aerosol for inhalation or exhalation. These devices typically include an atomizing module, which consists of an atomizing core and a reservoir. During operation, the atomizing core is heated, causing the oil in the reservoir to atomize. In actual use, if the reservoir is not sufficiently wetted with oil or the oil content is insufficient, the atomizing core may experience localized dry burning during heating. This can lead to unstable atomization, abnormal odors, and even damage to the atomizing core structure. Summary of the Invention

[0027] To fully understand this invention, detailed structures and steps will be presented in the following description to illustrate the technical solution proposed by this invention. Preferred embodiments of the invention are described in detail below; however, in addition to these detailed descriptions, the invention may have other embodiments.

[0028] Example 1 This embodiment provides a heating control method for an atomizing device. The atomizing device includes an atomizing module, which includes an atomizing core and an oil storage medium surrounding the atomizing core. The oil storage medium is used to absorb oil. A metal conductor is provided on the outside of the oil storage medium, and the metal conductor is in contact with the oil storage medium. Figure 1 As shown, the heating control method includes: Step S101. Obtain the capacitance value between the atomizer core and the metal conductor, as well as the capacitance threshold of the oil storage medium; Step S102. Determine the heating state of the atomizer core based on the capacitance value and capacitance threshold, wherein the heating state includes a heating-allowed state and a heating-prohibited state.

[0029] The atomizing core is the heating element, which can be a resistance wire, a heating element, or other conductive structure capable of generating heat when energized. During heating, the atomizing core converts electrical energy into heat energy, causing the oil adhering to its surface to vaporize. An oil-storing medium covers or surrounds the atomizing core, and has a porous or fibrous internal structure to adsorb and retain the oil. For example, the oil-storing medium can be oil-storing cotton. Because the air-to-oil ratio in the pores of the oil-storing medium varies under different wetting conditions, its overall dielectric constant changes; this change in physical properties affects the equivalent capacitance formed between it and surrounding conductors. A metal conductor is disposed outside the oil-storing medium and in contact with it. This metal conductor can be a metal sleeve, metal ring, metal sheet, or other conductive structural component. Through close contact with the oil-storing medium, it forms a stable electric field boundary, thus serving as the second electrode in the capacitance detection structure.

[0030] In step S101, the driving capacitance detection circuit applies a detection signal between the atomizing core and the metal conductor, making the atomizing core and the metal conductor form the two ends of the capacitance measurement. At this time, the oil storage medium is located between the atomizing core and the metal conductor, and its dielectric properties directly participate in the capacitance formation process. The capacitance detection circuit samples the equivalent capacitance between the atomizing core and the metal conductor to obtain a capacitance value used to characterize the wetting state of the oil storage medium. Specifically, when the oil storage medium is not fully wetted by the oil, the proportion of air in its pores is relatively high, and the overall dielectric constant is relatively low; when the oil fills the pores, the dielectric constant increases, thereby causing a change in the equivalent capacitance value. Therefore, by collecting this capacitance value, the wetting state of the oil storage medium can be indirectly determined. This step also includes obtaining a capacitance threshold. The capacitance threshold is a pre-set judgment benchmark value, which can be obtained through experimental calibration. For example, corresponding capacitance data are collected in the fully wetted and unwetted states, and the boundary value that can distinguish between the two states is selected as the capacitance threshold. The capacitance threshold can be set according to the type of oil storage medium material or the type of oil to adapt to different structural combinations.

[0031] In step S102, the currently detected capacitance value is compared with a capacitance threshold, and the working state of the atomizer core is determined based on the comparison result. When the capacitance value meets the preset condition, it indicates that the oil content inside the oil storage medium has reached the safe heating standard. At this time, the control module outputs a heating permission signal, causing the atomizer core to enter the heating permission state. When the detection result does not meet the threshold requirement, it indicates that the oil content in the oil storage medium is insufficient. To avoid dry burning, the control module outputs a heating prohibition command, keeping the atomizer core in a heating prohibition state. Through the above judgment logic, the power supply behavior of the atomizer core is controlled, thereby preventing the atomizer core from heating when the oil content does not meet the standard.

[0032] Because the oil storage medium has different dielectric properties under different oil wetting levels, the resulting equivalent capacitance value varies accordingly. This embodiment detects this capacitance parameter and compares it with a preset threshold to determine whether the oil storage medium is fully wetted before the atomizing core is heated. This control strategy restricts the atomizing core from being energized before the oil is fully absorbed, thus avoiding performance degradation or structural damage caused by localized high-temperature dry burning; allowing heating only after the oil meets the usage conditions helps ensure the stability of the atomization process. Therefore, this embodiment, by constructing a logical link of capacitance detection-threshold comparison-heating control, realizes a heating management mechanism based on the physical characteristics of the oil storage medium, improving the safety and consistency of equipment operation and reducing the impact of abnormal heating on the atomizing core's lifespan.

[0033] In one implementation, the metal conductor is a metal casing, and the metal casing is in contact with the oil storage medium; obtaining the capacitance value of the oil storage medium includes: Obtain the capacitance value between the atomizer core and the metal casing.

[0034] The metal shell, used to cover or support the atomizing module, can be a cylindrical shell, a sleeve-type shell, or a split conductive shell structure. During assembly, the metal shell is located on the outer circumference of the oil-storage medium and is brought into close contact with it through radial pressing, snap-fit ​​limiting, or interference fit, thereby ensuring the effective area and contact stability of the outer electrode during capacitance measurement. In this embodiment, the metal shell not only serves as a mechanical fixation and protection but also acts as the outer electrode of the capacitance detection structure. Due to its continuous conductive surface, it provides a stable potential boundary, creating a relatively fixed electric field distribution between the atomizing core and the metal shell, thus providing a clear measurement path for capacitance detection. In this embodiment, the capacitance detection circuit establishes a measurement path with the atomizing core as the first end and the metal shell as the second end. The oil-storage medium is located between the two ends, acting as a dielectric layer to participate in the formation of the equivalent capacitance. The capacitance detection circuit applies a detection excitation signal to the atomizing core and the metal shell and calculates the equivalent capacitance value between the atomizing core and the metal shell based on parameters such as the charge / discharge time constant, phase difference, amplitude change, or equivalent charge.

[0035] The technical advantages of this embodiment are as follows: the metal casing has a continuous and large conductive surface, which can form a stable electric field boundary; at the same time, its contact structure with the oil storage medium reduces capacitance drift caused by assembly gap fluctuations, making capacitance measurement results more consistent. Based on this, this embodiment can improve the reliability of oil storage medium wetting judgment, more effectively trigger the heating prohibition strategy when the oil is insufficient, thereby reducing the risk of dry burning; allowing heating only when the oil reaches the standard helps to improve the stability of the atomization process and reduce the probability of the atomizing core being subjected to abnormal thermal shock, thereby improving the overall safety and consistency of the equipment operation.

[0036] As one implementation method, obtaining the capacitance value between the atomizing core and the metal conductor includes: The capacitance between the atomizing core and the metal conductor is sampled multiple times within a preset time period, and the sampling results are filtered to obtain the capacitance value. The filtering process includes at least one of moving average filtering, median filtering, or low-pass filtering.

[0037] In the capacitance detection process, a preset time period (e.g., a detection window) is first set, and within this time period, the equivalent capacitance between the atomizing core and the metal conductor is repeatedly measured at a preset sampling frequency to obtain multiple sets of capacitance sampling data. This preset time period can range from tens to hundreds of milliseconds, and the sampling frequency can be configured according to the response speed of the capacitance detection chip or detection circuit, thereby increasing the number of samples while ensuring real-time performance. Due to factors such as switching drives, load changes, handheld vibrations, and external electromagnetic interference within the atomizing device, the capacitance data measured in a single measurement may exhibit transient changes or random fluctuations. To reduce the impact of these interferences on the judgment results, the control module filters the multiple sets of sampling data. The filtering process includes at least one of the following methods: Moving average filtering: A series of consecutive sampling points are used as a sliding window. The average value of the sampled data within the window is calculated and the calculation is rolled over as the sampling points are updated, thereby reducing the high-frequency fluctuations caused by random noise and making the capacitance curve smoother.

[0038] Median filtering: Multiple sampling points within the same window are sorted, and the median value is selected as the output. This method can effectively suppress outliers caused by occasional spikes and avoid biased judgment due to a single outlier.

[0039] Low-pass filtering: This involves applying a low-pass characteristic to the capacitor sampling sequence, attenuating high-frequency components while preserving slowly changing components related to the immersion state. Low-pass filtering can be implemented using digital filtering parameters or by a filtering unit within the detection circuit.

[0040] After the above filtering is completed, the filtered output is used as the final capacitance value between the atomizing core and the metal conductor, and this capacitance value is used for comparison with the capacitance threshold or for subsequent immersion state determination processes.

[0041] The technical advantage of this embodiment is that by sampling the capacitance between the atomizing core and the metal conductor multiple times within a preset time period, and combining processing methods such as moving average, median or low-pass filtering, the influence of transient interference, spike noise and sampling jitter on the capacitance detection results can be significantly reduced, making the obtained capacitance value more stable and repeatable. This improves the accuracy of judging the wetting state of the oil storage medium and the reliability of heating control decisions, and reduces the risk of abnormal heating caused by misjudgment.

[0042] As one implementation method, such as Figure 2 As shown, obtaining the capacitance value between the atomizer core and the metal conductor also includes: Step S201. Obtain the historical number of heating cycles or historical heating time of the atomizer core; Step S202. Generate heat load compensation parameters based on historical heating times or historical heating durations; Step S203. Correct the capacitance value according to the thermal load compensation parameters.

[0043] In step S201, the heating behavior of the atomizer core is recorded to form historical heating information that can be used for compensation. Specifically, each time the atomizer core is driven into the heating state, a heating event is recorded, and the duration of the heating event can be timed simultaneously. The resulting historical heating information includes at least one of the following: historical heating count: the cumulative number of times the atomizer core has been activated for heating within a preset statistical period; historical heating time: the total duration the atomizer core has been in the heating state within the preset statistical period. The preset statistical period can be set to since power-on, since the last atomizer core replacement, the last N vaping cycles, the last T minutes / hour, etc., to meet the compensation sensitivity requirements of different application scenarios. To avoid premature historical data from excessively influencing the current judgment, the control module can also use a sliding window method to only count the heating count or heating time within a recent period.

[0044] In step S202, heat load compensation parameters are generated based on the historical heating information obtained in step S201. These parameters characterize the degree of heat accumulation experienced by the atomizing core and the oil storage medium. The heat load compensation parameters can be constructed in any of the following ways: Segmented mapping method: Matching historical heating counts or historical heating times with multiple threshold intervals: when falling into different intervals, outputting different levels of compensation parameters. For example, dividing historical heating counts into low / medium / high heat load levels, and setting different compensation coefficients for each level.

[0045] Weighted accumulation method: Weights are assigned to historical heating events, so that heating events closer to the current moment have higher weights, thereby obtaining compensation parameters that can reflect recent heat accumulation and avoiding unnecessary deviations in current judgments caused by long-term heating.

[0046] Function calculation method: The control module generates heat load compensation parameters based on the number of historical heating times N or the total historical heating time T through a preset compensation function. For example, the compensation parameters are set to values ​​that change monotonically with N or T to describe the degree of influence of heat load on capacitance measurement.

[0047] In step S203, the measured original capacitance value is fused with the thermal load compensation parameters to obtain a corrected capacitance value for judgment. Specifically, the capacitance value can be biased or proportionally corrected according to the thermal load compensation parameters. For example, when the thermal load compensation parameters indicate high heat accumulation, a corresponding correction amount is applied to the capacitance value to offset capacitance drift caused by temperature hysteresis, changes in oil viscosity, or changes in the microstructure of the oil storage medium; when the thermal load compensation parameters indicate low heat accumulation, the correction is reduced or not applied to keep the capacitance value as sensitive as possible to the actual wetting state. The corrected capacitance value can be used as input for subsequent threshold comparison and heating state judgment, thereby making the judgment logic more consistent with the actual physical state under continuous use scenarios.

[0048] The technical effect of this embodiment is that by introducing the historical heating times or historical heating time of the atomizing core to generate heat load compensation parameters, and correcting the capacitance value accordingly, the influence of heat accumulation effect caused by continuous operation or high-frequency use on the capacitance detection result can be effectively reduced, making the correspondence between capacitance value and oil storage medium wetting state more stable, thereby improving the accuracy of oil content judgment and the reliability of heating control decision, and reducing the risk of misjudgment and abnormal heating caused by capacitance drift.

[0049] As one implementation method, such as Figure 3 As shown, obtaining the capacitance threshold of the oil storage medium includes: Step S301. Obtain the material of the oil storage medium and the type of oil; Step S302. Obtain the corresponding capacitance threshold according to the material of the oil storage medium and the type of oil.

[0050] The process begins by acquiring the material information of the oil storage medium. This information can be determined through preset configuration parameters, production codes, atomizer core model identifiers, or a material list stored in the device's memory. For example, after the atomizing module is assembled or the atomizer core is replaced, the material identifier corresponding to that module is read to determine whether the oil storage medium is fibrous, porous ceramic, composite adsorbent, or another type of oil-absorbing material. After obtaining the material information, the oil type is further acquired. This type can be confirmed through user selection, oil identification markers, formula numbers, or an oil parameter table linked to the atomizing module. The oil type characterizes differences in dielectric constant, viscosity, and polar component ratios, which alter the equivalent dielectric environment after the oil storage medium is immersed, thus affecting the variation of the capacitance detection value. Subsequently, based on the combination relationship between "oil storage medium material" and "oil type," a corresponding capacitance threshold is selected from a pre-established threshold set. The threshold set can be obtained through experimental calibration: capacitance data are collected under different material and oil conditions, including "fully wetted" and "insufficiently wetted" states, and the boundary values ​​that can distinguish between heating-allowed and heating-prohibited states are determined accordingly. For ease of use, the threshold set can be stored in the form of a lookup table, where each record corresponds to a material type and an oil type, and is associated with one or more capacitance threshold parameters. In some implementations, if a change in material or oil type is detected (e.g., replacing the atomizer coil or switching oil formulations), the threshold matching process can be re-executed to ensure that the thresholds remain consistent with the current combination.

[0051] The technical advantage of this embodiment is that by obtaining the material and type of the oil storage medium and selecting the corresponding capacitance threshold based on their combination, the adaptation error caused by using a single fixed threshold can be avoided. This makes the threshold more consistent with the differences in dielectric properties of different materials and different oils, thereby improving the ability of capacitance determination to distinguish the wetting state, reducing the probability of misjudgment, and improving the reliability and consistency of heating control.

[0052] As one implementation method, such as Figure 4 As shown, obtaining the capacitance threshold of the oil storage medium also includes: Step S401. Obtain the temperature value of the oil storage medium; Step S402. Correct the capacitance threshold based on the temperature value.

[0053] In step S401, the temperature value can be acquired by a temperature sensor located near the atomization module. For example, the temperature sensor can be positioned close to the e-liquid medium or the atomizer core to reflect the temperature changes of the environment in which the e-liquid medium is located. Alternatively, the temperature can be indirectly estimated based on the resistance change of the atomizer core. That is, given the known resistance-temperature characteristics of the atomizer core material, the corresponding temperature can be calculated from the real-time resistance value, thus obtaining temperature information without adding additional hardware. To ensure the stability of the temperature data, the temperature sampling values ​​can be de-jittered or averaged over a short period to reduce the impact of temperature fluctuations caused by instantaneous disturbances on the threshold correction.

[0054] In step S402, the dielectric properties of the oil storage medium and the oil change with temperature, which may cause the capacitance value of the same immersion state to shift at different temperatures. If a fixed threshold is still used for comparison, misjudgment is likely to occur in low-temperature or high-temperature scenarios. Therefore, this embodiment introduces temperature correction to dynamically adjust the capacitance threshold according to the temperature conditions. The specific correction method can be implemented in any of the following ways: Interval Correspondence Method: The temperature range is pre-divided into multiple temperature intervals, and a corresponding capacitance threshold is configured for each temperature interval. When the temperature value falls into a certain interval, the control module calls the threshold corresponding to that interval as the corrected threshold.

[0055] Function compensation method: A temperature-threshold correction relationship is preset in the memory, and the correction amount is calculated based on the temperature value. The correction amount is then added to the original threshold to obtain the target threshold. The correction relationship can be obtained through experimental calibration, reflecting the capacitance drift law of the oil storage medium material and oil at different temperatures.

[0056] Lookup table mapping method: The corresponding threshold entry is retrieved from the lookup table based on the temperature value. The lookup table can store multiple threshold points at the temperature granularity and can use interpolation to generate the target threshold corresponding to the temperature value to improve the correction accuracy.

[0057] After the threshold correction is completed, the corrected capacitance threshold is used to compare with the real-time capacitance value to determine the immersion state of the oil storage medium and further determine the heating state of the atomizer core.

[0058] The technical effect of this embodiment is that by obtaining the temperature of the oil storage medium and correcting the capacitance threshold accordingly, the dielectric characteristic drift caused by temperature changes can be effectively compensated, so that the capacitance threshold can maintain better adaptability under different ambient temperatures and different continuous operating conditions, thereby improving the accuracy and stability of the immersion state determination, reducing the risk of misjudgment caused by temperature deviation, and improving the reliability of heating control.

[0059] As one implementation method, such as Figure 5As shown, the heating state of the atomizer core is determined based on the capacitance value and capacitance threshold, including: Step S501. Obtain the oil content status in the oil storage medium based on the parameter relationship between the capacitance value and the capacitance threshold; Step S502. Determine the heating state of the atomizer core based on the oil content.

[0060] In step S501, the acquired capacitance value is used as the current detection quantity, and the capacitance threshold is used as the judgment criterion. The two are compared and calculated to obtain the oil content status that describes the current oil supply capacity of the oil storage medium. Specifically, the control module divides the oil content status into at least two categories according to preset judgment rules: for example, "reaching the heating standard value" and "not reaching the heating standard value".

[0061] In step S502, based on the oil content status obtained in step S501, a heating control result for the atomizer core is generated, and a corresponding control signal is output to drive the heating circuit to execute. For example, when the oil content status indicates "heating standard value has been reached," the control module sets the heating status of the atomizer core to the allowed heating state and provides power to the atomizer core, thereby enabling normal atomization operation; when the oil content status indicates "heating standard value has not been reached," the heating state is switched to the prohibited heating state, and the atomizer core is kept unheated or derated by turning off the drive switch or limiting the power output to avoid abnormal temperature rise when the oil supply is insufficient.

[0062] The technical advantage of this implementation is that by first generating the oil content state based on the capacitance value and capacitance threshold, and then determining the heating state of the atomizing core based on the oil content state, the risk of abnormal heating under insufficient oil supply is reduced, and the consistency and safety of the atomization process are improved.

[0063] As one implementation method, such as Figure 6 As shown, the state of oil content in the oil storage medium is obtained based on the capacitance value and capacitance threshold, including: Step S601. When the capacitance value is less than the capacitance threshold, determine that the oil content in the oil storage medium has reached the heating standard value; Step S602. When the capacitance value is greater than the capacitance threshold, it is determined that the oil content in the oil storage medium has not reached the heating standard value.

[0064] In step S601, the capacitance value output by the capacitance detection circuit has an inverse relationship with the degree of wetting of the oil storage medium. Specifically, when the oil storage medium is fully wetted, the dielectric environment tends to be stable, and the value output by the detection circuit decreases relatively; while when the oil is insufficient or not fully wetted, the capacitance value output by the detection circuit increases. To improve the stability of the judgment, the control module can compare the capacitance values ​​of multiple consecutive detection cycles, and only confirm the oil content status when the results of multiple comparisons are consistent, or set a certain hysteresis interval near the capacitance threshold to avoid frequent state switching caused by numerical fluctuations.

[0065] In step S602, there are areas inside the oil storage medium that are not filled with oil, causing the value output by the capacitor detection circuit to be higher than the reference value under the fully immersed state. Based on this comparison result, the oil content state is marked as not meeting the heating conditions, and this state is used for subsequent heating control decisions, such as triggering heating prohibition or limiting power output.

[0066] By directly comparing the capacitance value with the capacitance threshold, the oil content judgment logic and the output characteristics of the detection circuit can be kept consistent, reducing the risk of abnormal heating when the oil is insufficient and enhancing the safety and consistency of equipment operation.

[0067] As one implementation method, such as Figure 7 As shown, the heating state of the atomizer core is determined based on the oil content and state, including: Step S701. When the oil content in the oil storage medium reaches the heating standard value, determine that the heating state of the atomizing core is the allowable heating state; Step S702. When the oil content in the oil storage medium does not reach the heating standard value, the heating state of the atomizing core is determined to be the prohibited heating state.

[0068] In step S701, the oil content status obtained from the aforementioned determination is received. When this status indicates that the oil content inside the oil storage medium is sufficient and can meet the oil supply conditions required for atomization, a heating permission command is output, causing the atomizing core to enter the heating permission state. Specifically, an enable signal can be sent to the heating drive circuit to turn on the power switching device, thereby providing electrical energy to the atomizing core, enabling it to heat up normally and perform atomization. In some implementations, the control module can also set the corresponding heating power or duty cycle according to the current working mode under the premise of heating permission to ensure the stability of the atomization process. To enhance system stability, a confirmation check can also be performed when the oil content status changes from "not satisfied" to "satisfied," for example, the capacitance value can be checked again before entering the heating permission state to avoid false triggering of heating due to critical fluctuations.

[0069] In step S702, the atomizer core can be prevented from being powered on by turning off the power switch, stopping the output drive signal, or limiting the current output. This control strategy avoids continued heating when the e-liquid supply is insufficient, thereby reducing the risk of localized overheating, dry burning, or material damage. In a further implementation, when the system is in a heating-prohibited state, the control module can also trigger a prompt mechanism, such as outputting a status signal or indicator light, so that the user or the upper-level system can take appropriate measures.

[0070] By establishing a one-to-one correspondence between the oil content and the heating state of the atomizer core, a heating control logic based on the oil supply capacity of the oil storage medium is realized. Normal operation is allowed when the oil is sufficient, and heating is actively limited or blocked when the oil is insufficient, thereby effectively reducing the risk of dry burning, improving the stability and safety of the atomization process, and extending the service life of the atomizer core.

[0071] As one implementation, the capacitance threshold includes a first capacitance threshold and a second capacitance threshold, and the heating state also includes a power-limited heating state; determining the heating state of the atomizing core based on the capacitance value and the capacitance threshold includes: When the capacitance value is less than the first capacitance threshold, the heating state of the atomizing core is determined to be the allowable heating state; When the capacitance value is greater than or equal to the first capacitance threshold and less than the second capacitance threshold, the heating state of the atomizing core is determined to be the power-limited heating state. When the capacitance value is greater than or equal to the second capacitance threshold, the heating state of the atomizer core is determined to be the prohibited heating state.

[0072] When determining the heating state of the atomizer core based on the oil content, a graded heating control strategy can be adopted to improve the system's stability under critical oil conditions. Specifically, in addition to permitted heating and prohibited heating states, at least one intermediate control state can be set, such as a power-limited heating state. When the oil content is sufficient, the atomizer core operates normally according to the preset target power or duty cycle; when the oil content approaches the critical standard value, heating is not immediately and completely prohibited, but the output power of the atomizer core is reduced or its maximum duty cycle is limited, allowing the atomizer core to operate under controlled thermal load conditions; when the oil content is lower than the safe heating requirement, the control module outputs a heating prohibition command, shuts down the drive circuit or cuts off the power output, thereby preventing abnormal temperature rise under insufficient oil supply.

[0073] In further implementation, multiple judgment intervals can be defined based on the degree of deviation of the capacitance value from the capacitance threshold. For example, a hysteresis interval can be formed by setting a first threshold and a second threshold. When the capacitance value falls into the oil-sufficient interval, the system enters the allowed heating state; when the capacitance value is in the critical interval, the system enters the power-limited heating state; and when the capacitance value falls into the oil-insufficient interval, the system enters the prohibited heating state. By using interval-based judgment, frequent switching of heating states caused by fluctuations in the detected value near the threshold can be avoided. In addition, to enhance the stability of state switching, a confirmation mechanism can be introduced. For example, the heating state can be updated only when the capacitance detection result meets the switching conditions for several consecutive detection cycles, or a hold time can be set after the state switch, during which the reverse triggering condition can be ignored. Through the above control strategy, the heating behavior is kept consistent with the actual oil supply capacity of the oil storage medium, reducing the risk of fluctuations under critical operating conditions.

[0074] By adopting a graded heating control and hysteresis judgment mechanism, this implementation method can achieve smooth transition control during changes in oil content, reduce the impact of frequent start-stop of the atomizing core on the structure and circuit, and promptly limit or prohibit heating when the oil is insufficient, thereby improving the safety and stability of equipment operation and extending the service life of the atomizing core.

[0075] As a further implementation, after determining that the heating state of the atomizing core is a power-limited heating state, the method further includes: Adjust the heating power of the atomizer core to be lower than the preset power value.

[0076] In the limited-power heating state, the output of the atomizer core can be gradually adjusted so that the heating power gradually transitions with changes in the oil supply capacity, rather than jumping directly between different states. Specifically, after obtaining the capacitance value between the atomizer core and the metal shell, this capacitance value is first compared with the boundary of an interval used to characterize the risk of insufficient oil, to determine how close the current capacitance value is to the insufficient oil interval; when it is determined that the capacitance value is gradually approaching the insufficient oil interval, heating is not immediately switched to prohibited, but a corresponding power adjustment is generated based on the degree of proximity, and the heating intensity of the atomizer core is reduced accordingly.

[0077] In one implementation, the power limiting range is divided into multiple sub-ranges, and different output upper limits are configured for each sub-range. For example, the power limiting range can be divided into a first sub-range, a second sub-range, and a third sub-range based on the capacitor value, from near the oil-sufficient side to near the oil-deficient side. When the capacitor value is in the first sub-range, the target power is only slightly reduced. When the capacitor value enters the second sub-range, the PWM duty cycle upper limit is further reduced or the output voltage is lowered. When the capacitor value falls into the third sub-range, the power is compressed to a lower safety level, and preparations are made to trigger a heating shutdown if the situation continues to deteriorate. This segmented reduction method allows the power adjustment to be a step-like but continuously controllable process.

[0078] In another implementation, a proportional adjustment strategy is employed. This involves calculating a power attenuation coefficient based on the difference between the capacitance value and the interval boundary, and then using this coefficient to adjust the PWM duty cycle or output voltage. For example, using a critical interval near the capacitance threshold as the adjustment range, the attenuation coefficient decreases as the capacitance value approaches the boundary of the insufficient oil range, resulting in a gradual reduction in output power. Conversely, as the capacitance value moves away from the insufficient oil range, the attenuation coefficient approaches 1, bringing the heating output closer to normal levels. By adjusting proportionally, the power output can form a continuous curve with capacitance changes, thus achieving smooth power reduction.

[0079] Furthermore, to avoid frequent power fluctuations caused by detection noise, a rate-of-change limit can be added to the power regulation, that is, limiting the maximum change in PWM duty cycle or output voltage within each control cycle; or the capacitor value can be filtered and its trend judged before calculating the attenuation coefficient, and power reduction adjustment can only be performed when the capacitor value continues to change in the direction of insufficient oil. By introducing rate-of-change constraints and stability processing, the gradual adjustment process becomes smoother.

[0080] Through the above-mentioned gradual adjustment strategy, as the oil content gradually decreases and the oil supply capacity weakens, the heat load of the atomizer core can be reduced simultaneously, thereby reducing the risk of local overheating and dry burning. At the same time, compared with reducing the power all at once or directly cutting off the heating, gradual adjustment can avoid the sudden drop in atomization or sudden change in taste caused by sudden output changes, improve the consistency of experience in continuous use scenarios, and make the heating control decision more in line with the dynamic change process of the oil.

[0081] As another extended implementation, when the system enters a heating-prohibited state due to insufficient oil content in the storage medium, an automatic recovery logic can be introduced. This allows the device to automatically return to an operational state once the oil content is restored, reducing the need for manual intervention and improving operational continuity. Specifically, the capacitance detection process continues to operate in the heating-prohibited state, continuously acquiring the capacitance value between the atomizing core and the metal shell according to a preset cycle. This capacitance value is then compared with the criteria used to characterize sufficient oil content to determine whether the storage medium has regained the heating standard.

[0082] In one implementation, a continuous confirmation mechanism for recovery determination is set up. When the capacitance value is detected to meet the oil sufficiency condition, the heating prohibition is not immediately lifted; instead, this result is added to the recovery confirmation count. Only when the capacitance value meets the oil sufficiency condition for multiple consecutive detection cycles is the oil content status updated to meet the heating standard value, and a lifting command is output, switching the atomizer core from the heating prohibition state to the heating allowance state. This continuous confirmation method avoids false recovery caused by instantaneous noise, contact disturbances, or critical fluctuations.

[0083] In further implementation, to improve the robustness of the recovery process, a recovery confirmation threshold can be set, creating a hysteresis between the recovery criterion and the criterion for entering the prohibited state. Specifically, a first judgment boundary is used when entering the prohibited heating state, while a stricter second judgment boundary is used when de-prohibiting, thus requiring the capacitance value to reach a more sufficient oil sufficiency level before allowing heating to resume. This dual-threshold strategy can reduce the repeated switching between prohibition-recovery-re-prohibition when the oil content hovers near the critical region.

[0084] In another implementation, a recovery waiting time can be set. When the capacitance value first meets the oil sufficiency condition, a timer is started, and the capacitance value is continuously monitored during the recovery waiting time. Only if the capacitance value remains at the oil sufficiency condition during the waiting time is the de-prohibition operation performed. If the capacitance value fails to meet the condition again during the waiting time, the timer is reset and the heating is kept in the prohibited state. By introducing time gating, recovery jitter can be further reduced, which is especially suitable for scenarios where oil backflow requires a certain amount of time.

[0085] Furthermore, to avoid instantaneous thermal shock to the atomizer coil caused by frequent recovery, the control module can first enter a power-limited heating state or adopt a soft-start strategy after the restriction is lifted. That is, in the initial recovery phase, the atomizer coil is driven with a lower duty cycle or lower output voltage, and then gradually increased to the target power while the capacitor value remains stable. By gradually recovering the output, the recovery process can be smoother, while reducing the risk of re-dry burning due to the oil still being in a boundary state.

[0086] Through the above-mentioned automatic recovery logic, the system can automatically lift the heating ban after the oil content recovers and the state stabilizes, ensuring equipment availability and continuous use. At the same time, combined with constraint mechanisms such as continuous confirmation, recovery confirmation threshold or recovery waiting time, it can suppress frequent repeated recovery caused by critical fluctuations and improve the stability and reliability of heating state switching.

[0087] As one implementation method, an aging compensation mechanism can be introduced to reduce the impact of performance degradation of the oil storage medium and atomizing core during long-term use on capacitance detection results. Due to repeated heating and oil circulation, the oil storage medium may experience structural compression, porosity changes, or residue deposition, and carbides may adhere to the surface of the atomizing core, thereby altering the electric field distribution and overall dielectric environment, leading to capacitance drift under the same oil content conditions. If the initially calibrated capacitance threshold is still used for judgment, false judgments such as premature or delayed protection may occur. Therefore, it is necessary to dynamically correct the capacitance judgment parameters during equipment use.

[0088] In this embodiment, aging parameters characterizing the degree of use are generated by recording information such as the cumulative number of heating cycles, cumulative heating time, or equipment operation cycle of the atomizing core. The aging parameters can be divided into different aging stages according to preset segmentation rules, or a gradually changing aging compensation coefficient can be generated based on a continuous functional relationship. Subsequently, the capacitance threshold or the detected capacitance value is corrected according to the aging compensation coefficient, so that the judgment boundary is appropriately adjusted according to the degree of equipment aging, thereby maintaining a stable correspondence between the capacitance value and the actual oil content state.

[0089] In further implementation, adaptive adjustments can be made based on the changing trends of long-term capacitance data. When a stable shift in the overall capacitance reference value is detected, the judgment threshold is automatically fine-tuned to compensate for the effects of material aging or structural changes. Through these methods, the heating control logic can maintain reasonable protection sensitivity throughout the equipment's lifespan, reducing the probability of false alarms, improving the reliability of dry-burn protection, and extending the effective service life of the atomization module.

[0090] As an extended implementation, a safety priority control logic can also be set to prioritize the execution of safety protection strategies when multiple abnormal operating conditions exist simultaneously or when the detection results are uncertain, in order to prevent the atomizing core from continuing to heat under high-risk conditions. Specifically, in addition to acquiring the capacitance value and determining the oil content status, the system also simultaneously monitors safety-related parameters such as temperature, power status, and the health of the detection link, and sorts various safety events according to preset priorities. When a high-priority event is triggered, even if the oil content status shows that the heating standard is met, the control module will still prioritize outputting a heating prohibition command or a derating heating command.

[0091] In this implementation, safety events can be categorized into at least three priorities: a first priority, a second priority, and a third priority. The first priority event is an immediate risk event, triggering hard protection upon meeting any condition. The second priority event is a high-risk trend event, triggering power limiting or cooling down. The third priority event is a general abnormal event, used for alerts or enhanced detection confirmation. For example, a first priority event might include: the atomizing module temperature exceeding a preset safety limit, the atomizing core temperature rise rate exceeding a preset threshold, an abnormal power supply voltage causing uncontrollable drive operation, or an abnormal output from the capacitor detection module (e.g., open circuit, short circuit, saturation, over-range). A second priority event might include: a rapid deterioration of the capacitance value towards insufficient oil within a short period, repeated occurrences of critical range fluctuations, or a significant increase in the risk of dry burning due to excessive historical heating load. A third priority event might include: outliers in a single sampling, increased detection noise, or short-term instability in the contact state.

[0092] To implement the aforementioned priority strategy, a safety event scan is first performed within each control cycle. If a first-priority event is detected, the heating state is directly set to a prohibited heating state and locked until the release conditions are met, such as the temperature falling back to the safe recovery threshold and remaining stable for several detection cycles, or the fault flag being cleared before recovery is allowed. If the first priority event is not triggered, the control module then judges the second-priority event. If the second priority event is met, the heating state is switched to a power-limited heating state or enters a cooling waiting stage. During this stage, the capacitance value and temperature changes are continuously monitored to determine whether to further escalate to a prohibited heating state. When neither the first nor the second priority event is triggered, the control module executes the conventional control logic of allowing or prohibiting heating based on the oil content, thereby ensuring that the heating action is always under safe constraints.

[0093] In further implementation, to avoid state oscillations caused by frequent recovery, different recovery thresholds and waiting times can be set for different priorities. For example, a larger hysteresis band and a minimum cooling time can be used for the heating prohibition triggered by temperature over-limit, while the protection triggered by capacitor detection anomalies requires multiple consecutive normal detections before it is released; the power restriction for heating triggered by power supply anomalies can gradually increase the power after the voltage recovers and stabilizes. By configuring differentiated recovery strategies for different risk sources, the system can maintain the predictability and stability of control behavior while ensuring safety.

[0094] By adopting safety priority control logic, this implementation method can superimpose multi-dimensional safety constraints such as temperature, power supply and detection link health status in addition to oil content determination. When high-risk events such as overheating, power supply abnormality or sensor abnormality occur, heating can be blocked or limited in time, thereby significantly reducing the probability of runaway heating under abnormal operating conditions and improving the safety, reliability and robustness of atomization equipment operation.

[0095] Example 2 This second embodiment provides an atomizing device, such as... Figure 8 As shown, the atomizing device includes an atomizing body 101 and an atomizing module 201. The atomizing body 101 includes a control module 102. The atomizing module 201 includes an atomizing core 202 and an oil storage medium 203 surrounding the atomizing core 202. The oil storage medium 203 is used to absorb oil. The control module 102 is used for: Obtain the capacitance value and capacitance threshold of the oil storage medium 203; The heating state of the atomizing core 202 is determined based on the capacitance value and capacitance threshold, wherein the heating state includes a heating-allowed state and a heating-prohibited state.

[0096] The atomizing device includes an atomizing body 101 and an atomizing module 201. The atomizing body 101 includes a power supply, a switching circuit, and a control module 102. The atomizing module 201 is mounted on the atomizing body 101 and includes an atomizing core 202 and an oil storage medium 203 surrounding the atomizing core 202. The oil storage medium 203 is used to absorb and store oil, allowing the oil to be continuously supplied to the heating area when the atomizing core 202 is heated. The control module 102 is configured to acquire the capacitance value corresponding to the oil storage medium 203 and a preset capacitance threshold, and compare the two to determine the heating state of the atomizing core 202. When the comparison result shows that the oil content in the oil storage medium 203 reaches the heating standard value, the control module 102 controls the atomizing core 202 to enter the allowed heating state; when the oil content does not reach the standard, the control module 102 keeps the atomizing core 202 in the prohibited heating state.

[0097] Through the above structural design, the atomizing device can automatically control its heating behavior based on the capacitance change of the oil storage medium 203, thereby blocking heating when the oil is insufficient and allowing operation when the oil is sufficient, thus improving the safety and stability of the device operation.

[0098] As one implementation method, such as Figure 9 As shown, the atomizing module 201 also includes a metal shell 204, which is in contact with the oil storage medium 203. The atomizing body 101 also includes a capacitance detection module, which is connected to the atomizing core 202 and the metal shell 204 respectively. The control module 102 obtains the capacitance value between the atomizing core 202 and the metal shell 204 through the capacitance detection module, and uses it as the capacitance value of the oil storage medium 203.

[0099] The metal outer shell 204 is located outside and in contact with the oil storage medium 203, serving both structural support and protection, while also acting as the outer electrode in the capacitance detection structure. The capacitance detection module is electrically connected to both the atomizing core 202 and the metal outer shell 204, forming the two ends of the capacitance detection. Since the oil storage medium 203 is located between the atomizing core 202 and the metal outer shell 204, changes in its wetting state will cause changes in the equivalent capacitance between them. The capacitance detection module detects this equivalent capacitance value and transmits it to the control module 102. The control module 102 uses the capacitance value between the atomizing core 202 and the metal outer shell 204 output by the capacitance detection module as the capacitance input of the oil storage medium 203, for subsequent threshold comparison and heating state determination, thereby achieving heating control based on the wetting condition of the oil storage medium 203.

[0100] In one implementation, when executing the step "obtaining the capacitance between the atomizing core 202 and the metal conductor", the control module 102 is also used to: sample the capacitance between the atomizing core 202 and the metal conductor multiple times within a preset time period, and obtain the capacitance value after filtering the sampling results. The filtering process includes at least one of moving average filtering, median filtering, or low-pass filtering.

[0101] In one implementation, the control module 102, in performing the step "obtaining the capacitance between the atomizing core 202 and the metal conductor", is also used to: obtain the historical number of heating cycles or historical heating time of the atomizing core 202; generate heat load compensation parameters based on the historical number of heating cycles or historical heating time; and correct the capacitance value based on the heat load compensation parameters.

[0102] In one implementation, when the control module 102 performs the step "obtain the capacitance threshold of the oil storage medium 203", it is specifically used to: obtain the material and type of oil of the oil storage medium 203, and obtain the corresponding capacitance threshold according to the material and type of oil of the oil storage medium 203.

[0103] In one implementation, when the control module 102 performs the step "obtain the capacitance threshold of the oil storage medium 203", it is specifically used to: obtain the temperature value of the oil storage medium 203; and correct the capacitance threshold according to the temperature value.

[0104] In one implementation, when the control module 102 executes the step "determine the heating state of the atomizing core 202 based on the capacitance value and capacitance threshold", it is specifically used to: obtain the oil content state in the oil storage medium 203 based on the capacitance value and capacitance threshold; and determine the heating state of the atomizing core 202 based on the oil content state.

[0105] In one implementation, when the control module 102 executes the step "obtaining the oil content status in the oil storage medium 203 based on the capacitance value and capacitance threshold", it is specifically used to: determine that the oil content in the oil storage medium 203 has reached the heating standard value when the capacitance value is less than the capacitance threshold; and determine that the oil content in the oil storage medium 203 has not reached the heating standard value when the capacitance value is greater than the capacitance threshold.

[0106] In one implementation, when the control module 102 executes the step "determines the heating state of the atomizing core 202 based on the oil content state", it is specifically used to: determine the heating state of the atomizing core 202 as an allowed heating state when the oil content in the oil storage medium 203 reaches the heating standard value; and determine the heating state of the atomizing core 202 as a prohibited heating state when the oil content in the oil storage medium 203 does not reach the heating standard value.
