Detailed Implementation

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] The terms "first," "second," etc., used in the specification and claims of this invention are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, the first object can be one or more. Furthermore, the term "and / or" in the specification and claims is used to describe the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. In embodiments of this invention, the term "multiple" refers to two or more, and other quantifiers are similar.

[0015] Figure 1 This is a flowchart illustrating the steps of a method for measuring an atomized matrix according to an embodiment of the present invention, as shown below. Figure 1 As shown, the method may include the following steps: Step 101: Collect monitoring data of the atomizing device; the atomizing device includes a matrix chamber assembly, and the monitoring data includes at least the pressure monitoring data of the matrix chamber assembly.

[0016] Step 102: If it is determined that the atomizing device is performing a matrix injection operation based on the pressure monitoring data, the matrix injection amount is determined according to the matrix injection duration and the pressure monitoring data corresponding to the matrix injection operation.

[0017] Step 103: Determine the current inventory of atomizing matrix based on the matrix injection amount and the historical remaining matrix amount.

[0018] Regarding steps 101-103 above, the embodiments of the present invention can be applied to any atomizing device. The atomizing device in the embodiments of the present invention can be an atomizer, an aerosol generating device, etc., and the embodiments of the present invention are not limited thereto. Furthermore, the embodiments of the present invention can be applied to the controller or control unit (Microcontroller Unit, MCU) in the atomizing device.

[0019] The aforementioned monitoring data can characterize the pressure fluctuation of the atomizing device, and may include pressure monitoring data within the matrix chamber assembly; however, this embodiment of the invention does not impose any limitations on this.

[0020] Specifically, the aforementioned atomizing device may include a matrix chamber assembly, which may include a component for containing the atomizing matrix and a component for injecting the atomizing matrix. This can be an atomizing matrix receiving chamber and an airway or filling structure connecting the receiving chamber. The aforementioned monitoring data may include at least pressure monitoring data of the matrix chamber assembly.

[0021] Accordingly, in this embodiment of the invention, a pressure sensor unit can be provided inside the matrix chamber assembly and on its wall surface to collect pressure signals from the matrix chamber assembly. Accordingly, step 101 above can obtain the aforementioned pressure monitoring data by receiving signals from the pressure sensor unit of the atomizing device.

[0022] Based on this, the aforementioned pressure monitoring data can be used to monitor pressure fluctuations in the matrix chamber assembly. It should be noted that when the atomizing device performs a matrix injection operation, the atomized matrix occupies the original air volume in the matrix chamber assembly, causing pressure changes within the assembly. Therefore, in this embodiment of the invention, the pressure changes in the matrix chamber assembly can be monitored using the pressure monitoring data. This pressure monitoring data facilitates the detection of matrix injection events and the detection of matrix inventory levels based on pressure changes.

[0023] The aforementioned matrix injection operation refers to the replenishment of the atomizing matrix in the atomizing device. Users can replenish the atomizing matrix in the atomizing device according to their actual needs through the matrix injection end or matrix injection interface in the atomizing device.

[0024] It should be noted that after performing the matrix injection operation, in order to help users understand the matrix level and avoid matrix leakage or damage to the atomizing core caused by using the atomizing device normally when the matrix level is too high or too low, it is necessary to check the matrix level promptly after the matrix injection operation.

[0025] In related technologies, the amount of substrate is often determined by directly measuring the liquid level using a liquid level sensor (capacitive liquid level sensor, resistive liquid level sensor, or optical liquid level sensor). However, liquid level sensors are often expensive, and during the substrate injection process, phenomena such as substrate impact, bubble generation, and adhesion to the walls can easily lead to errors in the data from the liquid level sensor, resulting in poor accuracy in detecting the amount of substrate.

[0026] In this embodiment of the invention, the use of a liquid level sensor is avoided. Instead, the matrix injection amount is determined based on the matrix injection time and the pressure monitoring data corresponding to the matrix injection operation, and then the current matrix quantity is determined based on the matrix injection amount.

[0027] The aforementioned matrix injection duration refers to the duration of the matrix injection operation. The pressure monitoring data corresponding to the matrix injection operation refers to the pressure monitoring data of the atomizing device during the matrix injection process. It is understood that during matrix injection, due to the sealing of the matrix chamber or the flow resistance of the vent, the air in the matrix chamber is compressed, resulting in pressure fluctuations. Based on this, embodiments of the present invention can pre-calibrate the atomizing device; that is, conduct a simulation experiment of the matrix injection operation on the atomizing device in advance, and detect the pressure monitoring data of the atomizing device during the experiment to obtain the pressure change characteristics of the atomizing device during the matrix injection process.

[0028] Accordingly, the collected pressure monitoring data can be compared with the pre-calibrated pressure change characteristics during the matrix injection process. If the data characteristics of some data segments in the pressure monitoring data are consistent with the pressure change characteristics during the matrix injection process, it can be determined that the atomizing device is performing a matrix injection operation.

[0029] Furthermore, based on fluid mechanics, when the matrix enters a closed or semi-closed chamber through the injection end, the instantaneous accumulation of gas pressure inside the chamber is often proportional to the instantaneous injection rate of the matrix. On this basis, the pressure monitoring data corresponding to the above-mentioned matrix injection operation can characterize the injection rate change during the matrix injection process to a certain extent.

[0030] Furthermore, in step 102 above, the embodiments of the present invention can obtain the matrix injection amount by integrating the pressure monitoring data corresponding to the matrix injection operation within the matrix injection time window using calculus. The matrix injection amount can characterize the total amount of matrix injected during the matrix injection process.

[0031] The aforementioned historical matrix remaining amount refers to the remaining matrix in the matrix chamber before the matrix injection operation. Specifically, the historical matrix remaining amount can be obtained by directly reading the most recently recorded matrix inventory from the database. Furthermore, the sum of the injected matrix amount and the historical matrix remaining amount can be directly determined as the current inventory of the atomizing matrix.

[0032] For example, taking the matrix injection amount as ΔV and the historical matrix remaining amount as Vcurrent, the current inventory of the atomized matrix Vnew = ΔV + Vcurrent can be obtained.

[0033] Optionally, embodiments of the present invention may further include: S104. If the current inventory is greater than the upper limit capacity of the atomizing device, the upper limit capacity is determined as the current inventory of the atomizing matrix.

[0034] The aforementioned upper limit capacity can be the maximum capacity of the matrix chamber of the atomizing device. It is understood that the current quantity of the matrix should not exceed the aforementioned upper limit capacity. Based on this, if the current quantity determined in step 103 is greater than the upper limit capacity, there may be an error due to external influencing factors. In this case, the calculated current quantity can be corrected, that is, the upper limit capacity can be directly determined as the current quantity of the atomizing matrix.

[0035] For example, taking the upper limit capacity as Vmax as an example, if the above Vnew is greater than Vmax, then Vnew can be corrected to Vmax.

[0036] In this embodiment of the invention, the above-described correction operations can avoid errors in subsequent logic execution caused by data overflow. Simultaneously, it ensures the logical consistency between the data and the atomizing device entity, preventing misjudgments of boundary conditions in the control logic in some cases.

[0037] Optionally, embodiments of the present invention may further include: S105. The current inventory is output to the display component of the atomizing device for display.

[0038] The aforementioned display components can be digital tubes, transistor displays, organic light-emitting diodes (OLEDs), etc., and of course, other types of display components are not limited in this embodiment of the invention. Accordingly, the aforementioned display components can be used to display the current quantity of the atomized matrix.

[0039] Specifically, the above display method can directly display the current inventory, or it can display the percentage of the current matrix inventory relative to the upper limit capacity. It can be set according to actual needs, and the embodiments of the present invention do not limit it.

[0040] Optionally, steps 102 and 103 in the embodiments of the present invention can be executed in real time during the matrix injection process, or they can be executed after the matrix injection is completed. Correspondingly, the above display method can be real-time display or it can be executed after the matrix injection is completed. The embodiments of the present invention do not limit this.

[0041] In this embodiment of the invention, the above method can realize intelligent and automated matrix inventory display, eliminating the need to manually reset the inventory display after matrix injection, thus further improving the intelligence of the atomization device.

[0042] In summary, the atomizing matrix measurement method provided in this embodiment of the invention can collect pressure monitoring data of the matrix chamber component of the atomizing device as monitoring data, and determine whether the atomizing device is performing a matrix injection operation based on the monitoring data. When it is determined that a matrix injection operation is to be performed, the matrix injection amount is determined based on the matrix injection duration and the corresponding pressure monitoring data. Furthermore, the current quantity of the atomizing matrix can be directly determined based on the matrix injection amount and the historical remaining amount. In this embodiment of the invention, the matrix injection operation can be detected through monitoring data, and the current quantity of the atomizing matrix can be accurately determined by determining the matrix injection amount and the historical remaining amount. This can, to a certain extent, avoid the risks of dry burning of the atomizing core and matrix leakage caused by insufficient or excessive atomizing matrix. At the same time, this embodiment of the invention can measure the atomizing matrix using pressure monitoring data, eliminating the need for a liquid level sensor. This reduces hardware costs and avoids the problem of poor measurement accuracy caused by air bubbles and wall adhesion during the matrix injection process when using a liquid level sensor, thus improving the measurement accuracy of the atomizing matrix to a certain extent.

[0043] Optionally, the step 102 above, which involves determining the matrix injection volume based on the matrix injection duration and the pressure monitoring data corresponding to the matrix injection operation, may specifically include the following in this embodiment of the invention: S1021. Obtain the pressure monitoring data corresponding to the matrix injection operation from the pressure monitoring data, and use it as data to be processed.

[0044] S1022. Determine the difference between the data to be processed and the preset reference pressure value, and use it as the data to be integrated.

[0045] S1023. Based on the matrix injection time, perform time integration on the data to be integrated to obtain the matrix injection amount.

[0046] The data to be processed can be pressure monitoring data within the time window corresponding to the matrix injection operation. Specifically, in this embodiment of the invention, the pressure monitoring data can be used to determine in real time whether to start the matrix injection operation. When it is determined that the matrix injection operation has started, the current time is recorded as the start time t. start Accordingly, after determining the end of the matrix injection operation through pressure monitoring data, the current time is recorded again as the end time t. end .

[0047] Specifically, in this embodiment of the invention, the start and end times can be determined using the aforementioned pressure monitoring data. Specifically, if the pressure monitoring data exhibits a preset change characteristic corresponding to the matrix injection operation, the matrix injection operation can be determined to have started. Correspondingly, if the pressure monitoring data no longer exhibits the aforementioned change characteristic corresponding to the matrix injection operation, the matrix injection operation can be determined to have ended.

[0048] Specifically, the variation characteristics corresponding to the above-mentioned matrix injection operation may include instantaneous positive pressure pulses, continuous high-frequency pressure oscillations due to gas-liquid displacement, or a specified pressure rise slope.

[0049] Furthermore, the time difference between the aforementioned start and end times can be determined as the matrix injection duration. Correspondingly, the pressure monitoring data between the aforementioned start and end times can be determined as the data to be processed.

[0050] It should be noted that, based on fluid mechanics, when the matrix enters a closed or semi-closed chamber through the injection end, the instantaneous accumulation of gas pressure inside the chamber is often proportional to the instantaneous injection rate of the matrix. Based on this, the pressure monitoring data corresponding to the above matrix injection operation can characterize the instantaneous injection volume during the matrix injection process to a certain extent.

[0051] The aforementioned reference pressure value can be a reference air pressure obtained by pre-calibrating the atomizing device, or the air pressure value of the matrix chamber component when there are no external influencing factors. Furthermore, the aforementioned data to be integrated can be the difference between the data to be processed and the reference pressure value. For example, taking the data to be processed as P(t) and the reference pressure value as Patm, the aforementioned data to be integrated can be P(t) - Patm.

[0052] Furthermore, in this embodiment of the invention, the data to be integrated can be integrated over time based on the matrix injection duration. That is, the data to be integrated is integrated within the time window corresponding to the matrix injection operation to obtain the matrix injection amount.

[0053] Optionally, step S1023 above can be: .

[0054] Wherein, k can be a conversion coefficient obtained by pre-calibrating the pressure change and the instantaneous injection volume, and can be set according to the actual scenario. This embodiment of the invention does not limit this.

[0055] In this embodiment of the invention, the total amount injected during the matrix injection process can be conveniently obtained based on fluid dynamics and calculus, thereby enabling the quantification of the dynamic injection amount.

[0056] Optionally, after the above-described operation of collecting monitoring data from the atomizing device, the embodiments of the present invention may specifically include: S21. Obtain the pressure change characteristics of the matrix chamber assembly based on the pressure monitoring data.

[0057] S22. If the pressure change characteristics satisfy the first characteristic corresponding to the matrix injection operation, determine that the atomizing device performs a matrix injection operation.

[0058] The first feature mentioned above can be the pressure change characteristics of the matrix chamber assembly obtained through pre-calibration during matrix injection. Accordingly, the first feature can include instantaneous positive pressure pulses, continuous high-frequency pressure oscillations caused by gas-liquid displacement, or a specified pressure rise slope. Accordingly, embodiments of the present invention can obtain instantaneous pressure pulses, high-frequency pressure oscillation ranges, and pressure rise slopes based on pressure monitoring data as pressure change characteristics.

[0059] Furthermore, in this embodiment of the invention, the pressure change characteristics can be compared with the first characteristic. If the instantaneous pressure pulse meets the specified range of the instantaneous positive pulse, the high-frequency pressure oscillation interval belongs to the high-frequency range specified by the first characteristic, and the pressure rise slope belongs to the rise slope range executed by the first characteristic, then it can be determined that the atomizing device performs a matrix injection operation.

[0060] In this embodiment of the invention, the matrix injection operation of the atomizing device can be detected by collecting pressure monitoring data through the first feature described above, thereby realizing the detection and judgment of matrix injection events.

[0061] Optionally, the monitoring data may further include the suction signal of the atomizing device, and the embodiments of the present invention may further include: S201. If it is determined that the suction signal does not meet the second characteristic corresponding to the suction state, the operation of obtaining the pressure change characteristics of the matrix chamber assembly based on the pressure monitoring data is performed.

[0062] The aforementioned suction signal can be used to detect whether the atomizing device is in a suction state. The suction state refers to the state in which the user is suctioning from the atomizing device. Correspondingly, the second feature can be the signal characteristics that the atomizing device meets during the suction state.

[0063] It should be noted that when the atomizing device is in suction mode, the fluid rebound pressure (water hammer effect) at the moment of sudden suction stop, the reverse gas explosion of bubbles generated by heating and boiling, and the hydrostatic drift of the liquid column caused by the tilt of the suction posture will all generate pressure characteristics similar to those of a liquid injection event inside the matrix chamber assembly. Obviously, the pressure monitoring data collected on the matrix chamber assembly in suction mode cannot accurately characterize the liquid injection event to some extent. In this case, the embodiments of the present invention can further eliminate the interference caused by the suction mode through the above-mentioned suction signal.

[0064] Specifically, the aforementioned suction signal can be a pressure signal from the airflow channel of the atomizing device, where the airflow channel can be the suction channel of the atomizing device, allowing the user to inhale the aerosol generated by the atomizing device through the airflow channel. Understandably, when the user inhales from the atomizing device, the airflow channel often generates negative pressure, and the negative pressure amplitude is often significant. Correspondingly, the aforementioned second characteristic can be that the negative pressure amplitude of the suction signal exceeds a preset threshold. If the negative pressure amplitude of the suction signal does not exceed the preset threshold, it can be determined that the suction signal does not satisfy the second characteristic, and it can be determined that the atomizing device is not in a suction state, thus eliminating interference from suction on the pressure monitoring data. Conversely, if the negative pressure amplitude of the suction signal exceeds the preset threshold, it can be determined that the suction signal satisfies the second characteristic, and it can be determined that the atomizing device is in a suction state; in this case, the operation of step S21 is unnecessary.

[0065] Optionally, the aforementioned suction signal can also be the operating power of the heating wire. It is understood that when the atomizing device is in suction mode, the operating power of the heating wire is often not lower than a preset lower power limit. Therefore, the aforementioned second feature can be that the operating power of the heating wire is higher than the aforementioned lower power limit. Optionally, the aforementioned suction signal can also be the on / off state of the suction switch of the atomizing device. Correspondingly, the aforementioned second feature can be that the suction switch is in the on state. The aforementioned suction switch can be a mechanical switch, but it can also be other types of switches; this embodiment of the invention does not limit this.

[0066] Furthermore, when it is determined that the atomizing device is not in a suction state, the pressure change characteristics of the matrix chamber component can be obtained based on pressure monitoring data.

[0067] In this embodiment of the invention, the second feature and the suction signal can eliminate suction interference to a certain extent. By obtaining the pressure change characteristics of the matrix chamber component when it is determined that the atomizing device is not in a suction state, the interference caused by suction on the pressure of the matrix chamber component can be avoided, thereby improving the accuracy of detection.

[0068] Optionally, the operation of obtaining the pressure change characteristics of the matrix chamber assembly based on the pressure monitoring data described above may specifically include, in embodiments of the present invention: S211. Obtain the difference between the instantaneous pressure value and the preset reference pressure value based on the pressure monitoring data, and use it as the pressure mutation value.

[0069] And / or, S212, obtain the pressure change rate of the matrix chamber assembly based on the pressure monitoring data.

[0070] And / or, S213, obtain the pressure change duration based on the pressure monitoring data.

[0071] And / or, S214, perform high-pass filtering on the pressure monitoring data to obtain a high-frequency signal.

[0072] The aforementioned reference pressure value can be a pre-calibrated environmental reference pressure. Specifically, when a matrix injection operation is performed, the injected matrix occupies the original volume, causing a sudden positive pressure buildup inside the matrix chamber. In this case, a sudden change in instantaneous positive pressure often occurs. Therefore, in this embodiment of the invention, the difference between the instantaneous pressure value and the reference pressure value can be obtained as a pressure change value, which can be used to determine whether to perform a matrix injection operation. It should be noted that the aforementioned pressure change value refers to the difference between the instantaneous pressure value and the reference pressure value. If the difference between the instantaneous pressure value and the reference pressure value is negative, it indicates a negative pressure change caused by the suction behavior. Further, in this embodiment of the invention, if the suction signal does not satisfy the second characteristic corresponding to the suction state, and the above S211 operation is performed, the obtained pressure change value is usually positive.

[0073] The aforementioned pressure change rate characterizes the rate of pressure change. It should be noted that weather changes or changes in geographical altitude can also cause air pressure fluctuations, but the rate of pressure change caused by these factors is often slow. In another scenario, an impact to the atomizing device can also cause pressure changes, but the rate of pressure change caused by these factors is often rapid. To eliminate pressure changes caused by the interference of these factors, this embodiment of the invention can also obtain the pressure change rate. Specifically, the aforementioned pressure change rate can be directly obtained by taking the first derivative of the pressure monitoring data.

[0074] The aforementioned pressure change duration can be the time it takes for a positive pressure pulse to exceed a preset threshold and then fall back to a reference pressure value. It is understood that the matrix injection process is a continuous process, often lasting for a certain period, such as 0.5 to 3 seconds. Pressure changes caused by sensor noise are typically less than 0.1 seconds, while pressure changes due to ambient air pressure are typically greater than 5 seconds. Based on this, embodiments of the present invention can further determine whether a pressure fluctuation is caused by matrix injection by measuring the pressure change duration.

[0075] The aforementioned high-frequency pressure signal can be a high-frequency oscillation wave from the pressure monitoring data. It should be noted that during the matrix injection process, there is often accompanying gas-liquid displacement resulting in bubble bursting, matrix flow turbulence, and gurgling sounds during matrix injection. These phenomena superimpose a high-frequency oscillation wave onto the pressure fluctuations generated by the matrix injection itself. Simply pressing the matrix chamber typically produces a smooth positive pressure wave. Therefore, this embodiment of the invention can obtain the high-frequency signal from the pressure monitoring data through high-pass filtering. Furthermore, by determining whether the high-frequency signal contains signals within the frequency range corresponding to the aforementioned phenomena, it can be determined whether the pressure fluctuation is caused by matrix injection.

[0076] In this embodiment of the invention, by acquiring at least one of pressure mutation value, pressure change rate, pressure change duration, and high-frequency signal, the accuracy of monitoring matrix injection operation can be improved to a certain extent.

[0077] Optionally, the first feature described above includes at least one of the following features: The pressure change feature is characterized by a pressure abrupt change value that is greater than a preset pressure threshold.

[0078] The pressure change rate in the pressure change characteristic is not less than a first preset change rate and not greater than a second preset change rate; the first preset change rate is less than the second preset change rate.

[0079] The pressure change duration in the pressure change feature is greater than a first preset duration and less than a second preset duration; the first preset duration is less than the second preset duration.

[0080] The high-frequency pressure signal in the pressure change characteristics includes a pressure signal within a preset frequency range.

[0081] The aforementioned pressure threshold can be a pre-set positive pressure threshold. In one case, the pressure threshold can be 50 Pa, but other values ​​can also be set according to actual conditions. This embodiment of the invention does not impose any limitations on this. Accordingly, when the pressure mutation value is greater than the preset pressure threshold, it indicates that the pressure change at this time is not caused by inhalation, nor is it a fluctuation caused by normal air pressure changes. It can be determined to a certain extent that it is a change caused by the matrix injection operation.

[0082] The first and second preset rates of change can be pre-set pressure change rates, with the first preset rate of change being less than the second preset rate of change. For example, the first preset rate of change, Kmin, can be 20 Pa / ms, and the second preset rate of change, Kmax, can be 200 Pa / ms. Of course, other values ​​can be set according to actual conditions, and this embodiment of the invention does not impose any limitations on this. Correspondingly, when the pressure change rate falls within the range [Kmin, Kmax], it indicates that the pressure change is not caused by weather changes or equipment collisions.

[0083] The first preset duration and the second preset duration can be preset pulse widths, with the first preset duration being shorter than the second preset duration. For example, the first preset duration Tmin can be 0.5 seconds, and the second preset duration Tmax can be 3 seconds. Of course, other values ​​can be set according to actual conditions, and this embodiment of the invention does not impose any limitations on this. Correspondingly, when the pressure change duration falls within the range [Tmin, Tmax], it indicates that the pressure change is not caused by sensor noise or changes in ambient air pressure.

[0084] The aforementioned preset frequency range can be a high-frequency range obtained by pre-calibrating the matrix injection operation. For example, the preset frequency range can be 10Hz to 50Hz, but other values ​​can be set according to actual needs; this embodiment of the invention does not impose any limitations on this. Specifically, when the high-frequency signal includes a signal within the aforementioned preset frequency range, it indicates that the pressure change contains a high-frequency oscillation wave, which may be caused by the matrix injection operation.

[0085] In this embodiment of the invention, the matrix injection operation can be monitored from different dimensions through the first feature described above, which improves the accuracy of monitoring to a certain extent, and thus improves the accuracy of matrix measurement.

[0086] For example, Figure 2 This is a schematic diagram of an application scenario provided by an embodiment of the present invention, such as... Figure 2As shown, the user can inject atomized matrix into the injectable chamber through the matrix injection end. Accordingly, during the matrix injection operation, pressure changes in the chamber can be detected by pressure sensors (e.g., Micro-Electro-Mechanical Systems Pressure Sensor, MEMS) and negative pressure sensors.

[0087] Specifically, the MCU can perform the aforementioned atomization matrix measurement steps using pressure monitoring data from the pressure sensor and negative pressure sensor. If the negative pressure sensor detects a value of 0, and the MEMS pressure sensor detects an irregular positive pressure waveform lasting approximately 3 seconds with a peak value of 300 Pa, then the atomization device can be determined to perform a matrix injection operation. The MCU can integrate the area of ​​the pressure waveform within these 3 seconds and, combined with a pre-calibrated coefficient k (e.g., 100 Pa / s corresponds to 0.5 ml), calculate the matrix injection volume to be approximately 0.6 ml. Furthermore, based on the system's recorded remaining volume of 0.2 ml before matrix injection, the current inventory can be updated to obtain the current matrix inventory = 0.2 + 0.6 = 0.8 ml.

[0097] In summary, the atomizing matrix measuring device provided in this embodiment of the invention can collect pressure monitoring data of the matrix chamber component of the atomizing device as monitoring data, and determine whether the atomizing device is performing a matrix injection operation based on the monitoring data.

This reduces hardware costs and avoids the problem of poor measurement accuracy caused by air bubbles and wall adhesion during the matrix injection process when using a liquid level sensor, thus improving the measurement accuracy of the atomizing matrix to a certain extent.
