Description

Technical Field

[0001] This invention belongs to the field of atomization equipment technology, specifically relating to an intelligent atomization method, system, terminal, and medium. Background Technology

[0002] With the popularization of nebulized inhalation therapy, electronic nebulized health care, and personalized drug delivery technologies, nebulization devices have been widely used in medical, healthcare, and daily consumer fields. Traditional nebulizers mostly use ultrasonic oscillation or electric heating principles to convert liquid drugs or functional solutions into inhalable aerosols for local or systemic absorption. In recent years, with the development of electronic control and sensing technologies, nebulization devices have gradually evolved towards miniaturization, intelligence, and wearability, requiring them to maintain nebulization efficiency and particle uniformity while possessing higher levels of energy efficiency management and usage safety.

[0003] Existing atomizing devices generally adopt a fixed parameter driving method, that is, the atomizing power, driving frequency and working time are preset at the factory, or the atomizing intensity can be adjusted through simple mode selection.

[0004] Such solutions can complete atomization operations in a single environment, but their control logic lacks dynamic correction capabilities. In actual use, changes in ambient temperature, humidity, and air pressure can affect the vibration characteristics of the atomizing plate and the viscosity of the liquid, which can easily lead to problems such as inconsistent dosage, uneven particle size, and poor stability.

[0005] On the other hand, although some improved devices have achieved automatic configuration of atomization parameters through information recognition technology, most of them rely solely on external labels or user input for identification. Traditional solutions often obtain information about the type of atomized liquid through barcodes, QR codes, or optical recognition. However, these methods depend on the lighting environment or shooting angle, have low recognition rates, and are easily affected by contamination or wear. They cannot achieve automatic, secure, and encrypted information exchange between the device and the atomization bottle. Summary of the Invention

[0006] This invention addresses the problems in the prior art by providing an intelligent atomization method, system, terminal, and medium. It solves the problems mentioned in the background section where environmental changes affect the vibration characteristics of the atomizing plate and the viscosity of the liquid, leading to inconsistent dosage, uneven particle size, and poor stability. Simultaneously, it solves the problem that the identification methods for obtaining atomized liquid type information have low recognition rates and are easily affected by contamination or wear, making it impossible to achieve automatic, secure, and encrypted information exchange between the device and the atomizing bottle.

[0007] The technical solution adopted in this invention is as follows: In a first aspect, this application provides a smart atomization method, which includes the following steps: Step S1: Obtain initial signals to characterize the properties of the atomizing liquid and the user's usage status. The initial signals include the atomizing liquid identification signal, the environmental status signal, and the user operation signal. Step S2: Extract the type information of the atomizing liquid based on the initial signal and calculate the corresponding atomization target parameters, including the target size of the atomized particles, the target atomization power, and the target atomization time; Step S3: Generate initial control commands for atomization based on the atomization target parameters. The initial control commands include initial power and initial time, and drive the atomization generator to perform atomization at the set initial power and initial time. Step S4: Acquire detection signals in real time during the atomization process. The detection signals include temperature signal, liquid level signal, liquid supply flow status signal, atomization output efficiency signal, and power output signal. Step S5: Set corresponding target parameters for each detection signal, calculate the deviation between the actual detection value and the target parameter, and when the deviation exceeds the preset range, select a controllable parameter to perform indirect compensation.

[0008] Furthermore, in step S1, the atomizing liquid identification signal obtains the type identifier of the atomizing liquid through electromagnetic induction, optical induction, or NFC communication. Environmental status signals include temperature (T), humidity (H), and air pressure (P); User operation signals include mode selection parameter M and inhalation intensity parameter I.

[0009] Furthermore, in step S2, the basic parameter vector is obtained by retrieving it from a preset parameter library based on the initial signal. ,in, These represent the rated particle size, rated atomization power, and rated atomization time of the atomizing fluid, respectively. Calculate the environmental correction coefficient vector based on the environmental state signal. Each component is calculated using the linear deviation correction formula:

[0010]

[0011]

[0012] in, This is the rated environmental reference value. This is the environmental sensitivity coefficient; Determine the user tuning coefficient vector based on the user operation signal. ; Calculated using the joint adjustment function of user intensity and pattern: , ; in, This is the inhalation intensity sensitivity coefficient. These are the mode correction coefficients. As a pattern indicator factor; Calculate the atomization target parameter vector:

[0013] These correspond to the target size of the atomized particles, the target atomization power, and the target atomization time, respectively.

[0014] Furthermore, the process of generating the initial atomization control command in step S3 includes: Output drive frequency signal based on target atomized particle size; Calculate the driving voltage and current signals based on the target atomization power, and output the driving power signal; Output a drive time signal based on the target atomization time; By combining the driving frequency signal, driving power signal, and driving time signal, an initial atomization control command is generated, and the atomization generator is driven to work according to the initial atomization control command.

[0015] Furthermore, in step S4, the detection signal is acquired and calculated in real time during the atomization process to characterize the atomization state; The temperature signal is detected in real time by temperature sensing elements deployed on the atomizing plate or cavity wall; The liquid level signal is used to measure the change in liquid level through an optical reflective or capacitive liquid level detector; Liquid supply flow status signal: The flow rate or pressure difference change of the liquid is obtained through the flow detection channel or differential pressure sensing element; The atomization output efficiency signal is obtained by acquiring the real-time current, voltage, or vibration feedback waveform of the atomization drive circuit and calculating the ratio between energy output and atomization quantity to characterize the atomization efficiency. The power output signal is obtained by sampling the voltage and current at the drive end and integrating them to obtain the actual power output. The above signals are periodically sampled, smoothed, filtered, and compared with thresholds. When the detection result deviates from the preset range, corresponding deviation information is generated.

[0016] Furthermore, in step S5, the detection signals of temperature, liquid level, liquid supply flow, atomization efficiency and power output are compared and analyzed to determine whether each detection result deviates from the target parameter range. When the deviation exceeds the set threshold, dynamic control is performed. Indirect compensation will be implemented using the following strategies: When the test results show that the temperature of the atomizing chamber is higher than the target range or the liquid level is lower than the lower limit, it is determined that there is a risk of overheating or dry burning, and the atomization intensity is reduced, and a combination of power reduction and frequency reduction is implemented. When the atomization output efficiency is lower than the target level, the atomization intensity is increased, and adjustments are made to increase power or frequency. When the liquid supply flow is unstable, reduce the frequency and power; When the drive output power does not reach the set target, increase the drive voltage or current.

[0017] Secondly, this application provides an intelligent atomization system for implementing the intelligent atomization method as described in the first aspect, the system comprising: Atomizing bottles are used to encapsulate pre-mixed atomizing liquids. The bottle body is equipped with an information identification unit, which is used to store the type identification and parameter information of the atomizing liquid. Atomizing chamber, used to hold and secure the atomizing bottle; An atomizing device is used to atomize the atomizing liquid under the drive of the main controller; The main controller is electrically connected to the information identification unit, the atomizing device, and multiple detection units in the detection unit group. The detection unit group includes a temperature detection unit, a liquid level detection unit, a liquid supply flow detection unit, an atomization efficiency detection unit, and a power detection unit, which are used to output real-time detection signals of temperature, liquid level, flow state, atomization efficiency, and power, respectively. The communication unit is used to realize wired or wireless communication between the information identification unit and the main controller. The communication methods include electromagnetic induction, optical identification or near-field communication. The human-computer interaction unit is used to display information about the atomizing liquid, atomization status and working mode, and to receive user input.

[0018] Furthermore, the main controller is used for: Acquire initial signals to characterize the properties of the atomizing fluid and the user's usage status; Extract atomizing fluid type information and calculate atomization target parameters based on the initial signal; Generate and issue initial atomization control commands to drive the atomization generator to work; During the atomization process, the system receives detection signals from the detection unit and performs deviation analysis. When the detected signal deviates from the target parameter range, one or more controllable parameters, such as power, frequency, or time, are selected to perform indirect compensation control.

[0019] Thirdly, this application provides a terminal, including: The memory is used to store the intelligent atomization program; A processor for executing the steps of the intelligent atomizing device as described in the first aspect of the intelligent atomizing method.

[0020] Fourthly, this application provides a computer-readable storage medium that stores computer instructions. When a computer reads the computer instructions in the storage medium, the computer executes the intelligent atomization method as described in the first aspect.

[0021] As can be seen from the above technical solutions, the advantages of the present invention are: By establishing a complete closed-loop process from initial signal acquisition, atomization target parameter calculation, control command generation, real-time detection, and dynamic adjustment, adaptive control can be achieved based on various real-time operating signals during the atomization process. This overcomes the problem that fixed parameters of traditional atomization equipment cannot be automatically corrected according to changes in environment and liquid level, and realizes dynamic matching of atomization power, frequency, and time, significantly improving the stability of atomized particles, dosage consistency, and overall safety of use.

[0022] By introducing electromagnetic induction, optical induction, or near-field communication to identify the type of atomizing fluid, the system can automatically identify the atomizing fluid formula and corresponding parameters without manual input. Combined with environmental status signals and user operation signals, the system can simultaneously perceive the external environment and user preferences, achieving personalized atomization control with "one parameter per bottle." This design improves the accuracy and real-time performance of information recognition, avoids the problems of barcode or optical recognition being susceptible to contamination and angular interference, and enhances the level of intelligence and ease of use.

[0023] By establishing a basic parameter vector and introducing an environmental correction coefficient vector and a user tuning coefficient vector for joint calculation, the atomization target parameters can be dynamically corrected according to the current environmental temperature, humidity, and pressure conditions and the user's usage intensity. This allows for the automatic matching of appropriate atomization power and time under different usage environments and inhalation intensities, effectively avoiding atomized particle size deviation and atomization efficiency reduction, and achieving adaptive optimization and individualized adjustment of atomization control.

[0024] By acquiring multiple detection signals, including temperature, liquid level, liquid supply flow status, atomization output efficiency, and power output, and performing periodic sampling, smoothing filtering, and threshold comparison on each signal, multi-dimensional monitoring of the atomization status and determination of operational stability can be achieved. This design overcomes the limitations of traditional single-signal detection, enabling early identification of problems such as overheating, dry burning, unstable liquid supply, or abnormal power, providing high-precision feedback data for subsequent dynamic control, and significantly improving the safety and reliability of the system.

[0025] In step S5, by analyzing the deviation between the multi-source detection signals and the target parameters and performing indirect compensation, the main controller can automatically select power, frequency, or time for dynamic adjustment according to different deviation types, realizing a multi-layered collaborative control mechanism of "safety first, efficiency maintenance, and stability compensation." When abnormal temperature or liquid level is detected, the intensity is automatically reduced; when atomization efficiency or power is insufficient, the output is automatically increased or the time is extended, thereby maintaining stable atomized dosage while adhering to safety boundaries. This control strategy effectively avoids overcompensation and frequent oscillations, achieving long-term stable, continuous, and highly consistent atomization output. Attached Figure Description

[0029] 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 embodiments of the present invention, and not all embodiments. 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.

[0030] Please see Figure 1 As shown, the present invention provides an intelligent atomization method, comprising the following steps: Step S1: Obtain initial signals to characterize the properties of the atomizing liquid and the user's usage status. The initial signals include the atomizing liquid identification signal, the environmental status signal, and the user operation signal. In this embodiment, the atomizing liquid identification signal can be obtained through an information identification unit set on the atomizing bottle body. This identification unit can be any one of a near-field communication (NFC) tag, an electromagnetic induction chip, or an optical identification mark. After the atomizing bottle is inserted into the device, the main controller automatically reads the atomizing liquid type identifier, formula number, and recommended atomization parameter information stored inside, thereby realizing automatic identification and matching of the atomizing liquid.

[0031] Environmental status signals can be acquired in real time by temperature, humidity and air pressure sensors installed inside the device casing to characterize the impact of the current environment on atomization efficiency and particle size.

[0032] User operation signals can be collected by the human-machine interface unit, including information such as the user's selected working mode, inhalation intensity, and usage time.

[0033] In a typical embodiment, when the user selects "Powerful Mode" through the interactive interface and detects that the room temperature is 25°C and the humidity is 40%, the system automatically integrates the atomized liquid identification information, environmental signals and user operation signals to form a complete set of initial signal data, providing an input basis for subsequent target parameter calculation.

[0034] Step S2: Extract the type information of the atomizing liquid based on the initial signal and calculate the corresponding atomization target parameters, including the target size of the atomized particles, the target atomization power, and the target atomization time; In this embodiment, the main controller first retrieves the basic parameter information corresponding to the identified nebulizer type from the built-in parameter library by parsing the initial signal. This includes the rated atomized particle size, rated atomization power, and rated atomization time of the nebulizer. Subsequently, the main controller adjusts the basic parameters based on environmental status signals and user operation signals. For example, when the ambient temperature is low or the air humidity is high, the system automatically increases the atomization power to compensate for the reduced atomization efficiency caused by changes in liquid viscosity; when the user selects a milder inhalation mode, the system reduces the power and extends the atomization time to maintain dose balance.

[0035] In one embodiment, when the drug liquid type is identified as "Drug Liquid A", its rated atomization power is 12W, the target particle diameter is 3 micrometers, and the current ambient temperature is low and the inhalation intensity is weak, the system automatically calculates the target atomization power as 14W and the target atomization time as 1.3 times the rated duration, thereby forming target parameters that are suitable for the current usage conditions.

[0036] Step S3: Generate initial control commands for atomization based on the atomization target parameters. The initial control commands include initial power and initial time, and drive the atomization generator to perform atomization at the set initial power and initial time. In this embodiment, the main controller generates corresponding control commands based on the target atomization parameters obtained in step S2. The control commands include a frequency signal for driving the atomizing plate to vibrate, voltage and current output parameters for controlling the drive circuit, and a time signal for controlling the duration of a single atomization process.

[0037] The generated control commands are output to the atomizing device via the power drive module, causing the atomizing plate to vibrate stably at a specified frequency, thus converting the atomized liquid into an aerosol that meets the particle size requirements.

[0038] In one specific embodiment, when the target atomization power is set to 14W and the atomization time is set to 60 seconds, the main controller outputs a corresponding voltage signal to the drive circuit to control the atomizing plate to vibrate at a stable frequency. The atomizing device maintains a constant power output throughout the entire atomization cycle to ensure that the generated atomized particles have a uniform particle size.

[0039] Step S4: Acquire detection signals in real time during the atomization process. The detection signals include temperature signal, liquid level signal, liquid supply flow status signal, atomization output efficiency signal, and power output signal. In this embodiment, the device continuously collects various operating status signals during atomization. Temperature signals can be obtained using temperature sensors installed on the atomizing plates or the walls of the atomizing chamber to reflect the actual operating temperature of the atomizing chamber; liquid level signals can be measured by optical reflective or capacitive sensors installed at the bottom of the liquid storage chamber to determine the remaining drug level; liquid supply flow status signals can be obtained by flow sensors or differential pressure sensors to reflect the continuity of drug flow; atomization output efficiency signals can be calculated by collecting the current, voltage, or vibration feedback waveforms of the drive circuit to evaluate energy conversion efficiency; and power output signals are obtained by sampling the real-time voltage and current of the drive circuit to determine whether the actual output power reaches the target.

[0040] In one embodiment, after the atomizing plate has been running continuously for thirty seconds, if the main controller detects that the temperature is maintained at 38°C, the liquid level drops steadily, the flow signal fluctuation rate is less than 5%, and the output power deviates from the set value by less than 2%, then the system determines that the atomization process is in a stable state; if a sudden drop in liquid level or a rapid rise in temperature is detected, the system immediately issues an alarm and records the deviation information.

[0041] Step S5: Set corresponding target parameters for each detection signal, calculate the deviation between the actual detection value and the target parameter, and when the deviation exceeds the preset range, select a controllable parameter to perform indirect compensation. In this embodiment, the main controller compares the real-time values ​​of each detection signal with a preset target range and performs dynamic adjustment based on the deviation. When the detected temperature is higher than the target range, the main controller reduces the drive power or frequency to suppress the risk of overheating; when the detected liquid level is low or the liquid supply flow is unstable, the system automatically reduces the atomization intensity and extends the atomization time to prevent dry burning and maintain consistent dosage; when the detected atomization efficiency or power output is lower than the target value, the power output is increased or the frequency is moderately increased to restore the atomization intensity.

[0042] In a typical embodiment, when the main controller detects that the atomization efficiency is about 10% lower than the target value, while the temperature and liquid level are normal, the system executes a "power increase fine-tuning" strategy to increase the power by about 5% while keeping the current frequency unchanged. When the efficiency recovers to the target range, the system automatically adjusts the power back to the normal level, achieving process self-stabilization and closed-loop correction.

[0043] In some embodiments, in step S1, the atomizing liquid identification signal obtains the type identifier of the atomizing liquid through electromagnetic induction, optical induction, or NFC communication. Environmental status signals include temperature (T), humidity (H), and air pressure (P); User operation signals include mode selection parameter M and inhalation intensity parameter I.

[0044] In this embodiment, the information identification unit on the atomizing bottle can employ a built-in electromagnetic response chip, an identification mark with an optical reflective layer, or a readable and writable near-field communication tag. When the atomizing bottle is installed in the atomization chamber, the communication unit within the device automatically activates the identification function, reading the atomizing liquid type number, production batch, recommended atomization power, and usage restrictions stored in the identification unit. This allows for automatic identification and matching of the atomizing liquid without manual input. This identification method enables data exchange in contact or close-range situations, avoiding the limitations of QR codes and barcodes that rely on light or camera recognition. It also offers advantages such as strong anti-contamination capabilities, fast identification speed, and high anti-counterfeiting performance.

[0045] Environmental status signals are acquired through temperature and humidity sensors and air pressure sensors installed in the equipment casing or airflow channels to monitor current environmental conditions in real time. Temperature signals reflect changes in gas viscosity and liquid volatility, humidity signals affect aerosol diffusion, and air pressure signals are used to correct airflow resistance and liquid supply stability. The system periodically collects these signals during startup and atomization, comparing them with factory baseline environmental data to provide a reference for subsequent target parameter adjustments.

[0046] User operation signals are acquired through the human-machine interface or the inhalation flow detection module. The mode selection parameter M can be selected by the user via buttons or a touchscreen from options such as "mild mode," "standard mode," and "powerful mode" to determine the initial ratio of nebulization output power and duration. The inhalation intensity parameter I can be measured by a micro-pressure sensor or airflow velocity sensor located in the inhalation channel, reflecting the intensity and rhythm of the user's inhalation in real time. The main controller dynamically adjusts the nebulization trigger timing and the nebulizer plate vibration cycle according to the trend of inhalation intensity changes, synchronizing the release of the atomized aerosol with the user's inhalation process, thereby improving inhalation efficiency and user comfort.

[0047] In some embodiments, in step S2, a basic parameter vector is obtained by retrieving it from a preset parameter library based on the initial signal. ,in, These represent the rated particle size, rated atomization power, and rated atomization time of the atomizing fluid, respectively. Calculate the environmental correction coefficient vector based on the environmental state signal. Each component is calculated using the linear deviation correction formula:

[0048]

[0049]

[0050] in, This is the rated environmental reference value. This is the environmental sensitivity coefficient; Determine the user tuning coefficient vector based on the user operation signal. ; Calculated using the joint adjustment function of user intensity and pattern: , ; in, This is the inhalation intensity sensitivity coefficient. These are the mode correction coefficients. As a pattern indicator factor; Calculate the atomization target parameter vector:

[0051] These correspond to the target size of the atomized particles, the target atomization power, and the target atomization time, respectively.

[0052] In some embodiments, the process of generating the initial atomization control command in step S3 includes: Output drive frequency signal based on target atomized particle size; Calculate the driving voltage and current signals based on the target atomization power, and output the driving power signal; Output a drive time signal based on the target atomization time; By combining the driving frequency signal, driving power signal, and driving time signal, an initial atomization control command is generated, and the atomization generator is driven to work according to the initial atomization control command.

[0053] In this embodiment, after obtaining the target atomized particle size, target atomization power, and target atomization time, the main controller maps these target parameters into drive signals executable by the device through its internal control logic module. The size of the atomized particles is closely related to the vibration frequency of the atomizing plate. Therefore, the main controller determines the drive frequency signal based on the target particle size, so that the atomizing plate operates at the optimal resonant frequency, thereby ensuring that the formed aerosol particles are uniform in size and within the set range.

[0054] For the power output section, the main controller calculates the required voltage and current control signals based on the target atomization power and sends them to the power drive circuit. The power drive circuit adopts a constant power control mode, maintaining stable output in real time through dual-channel feedback of voltage and current. This effectively prevents power deviations when the load changes or the liquid level drops, thereby avoiding fluctuations in atomization intensity.

[0055] The target nebulization time corresponds to the duration of a single nebulization cycle. When generating the drive time signal, the main controller combines the user's operating mode and historical usage records to rationally plan the duration of a single nebulization cycle, ensuring consistent dosage output. For example, when the system detects that the user is in "strong mode" and has a low inhalation frequency, it automatically extends the single nebulization time to achieve sufficient nebulization output; conversely, it appropriately shortens the time to avoid overdose.

[0056] The drive frequency signal, drive power signal, and drive time signal are integrated in the main controller to form a complete initial atomization control command. This control command includes parameters such as start-up timing, frequency control, power curve, and time termination point, and is sent to the control module of the atomizing device through the drive interface. After receiving the command, the atomizing device drives the atomizing plate to generate high-frequency oscillations at the set frequency, causing the atomized liquid to diffuse evenly through capillary channels, forming a micro-atomized aerosol with controllable particle size.

[0057] In a typical embodiment, the system identifies the current atomizing liquid as drug solution A, with a target atomized particle size of 3 micrometers, a target atomization power of 14 watts, and a target atomization time of 60 seconds. The main controller calculates a drive frequency of 120 kHz, an output voltage of 12 volts, and a current of 1.2 amps, and maintains a constant power output for 60 seconds. The device automatically starts after receiving complete initial control commands. The entire atomization process is stable, quiet, and without overheating. The atomized particle size distribution is concentrated, resulting in high drug utilization.

[0058] Through the above implementation method, this step achieves accurate mapping of atomization parameters to executable drive signals, enabling the device to enter a stable working state during the startup phase, significantly improving atomization efficiency and control accuracy, and providing a reliable control basis for subsequent detection and dynamic correction.

[0059] In some embodiments, in step S4, a detection signal is acquired and calculated in real time during the atomization process to characterize the atomization state; The temperature signal is detected in real time by temperature sensing elements deployed on the atomizing plate or cavity wall; The liquid level signal is used to measure the change in liquid level through an optical reflective or capacitive liquid level detector; Liquid supply flow status signal: The flow rate or pressure difference change of the liquid is obtained through the flow detection channel or differential pressure sensing element; The atomization output efficiency signal is obtained by acquiring the real-time current, voltage, or vibration feedback waveform of the atomization drive circuit and calculating the ratio between energy output and atomization quantity to characterize the atomization efficiency. The power output signal is obtained by sampling the voltage and current at the drive end and integrating them to obtain the actual power output. The above signals are periodically sampled, smoothed, filtered, and compared with thresholds. When the detection result deviates from the preset range, corresponding deviation information is generated.

[0060] In this embodiment, the main controller periodically collects data from multiple sensing elements and establishes a real-time operating data sequence with millisecond-level sampling intervals. The temperature detection element can be a thermistor or a MEMS temperature sensor, directly attached to the back of the atomizing plate or disposed on the cavity wall surface, for accurately measuring temperature changes in the atomization zone. When a gradual temperature increase is detected, the main controller can determine whether an overheating trend exists and take power limiting measures in advance, thereby effectively avoiding dry burning and material fatigue damage.

[0061] Liquid level detection employs either optical reflective or capacitive sensors. When the liquid level drops to a preset threshold, the intensity of the reflected signal or the rate of change of capacitance changes accordingly. Based on this, the system determines the remaining liquid volume and issues an alert or restricts atomization output when the liquid level falls below a warning line. By monitoring the liquid level signal in real time, dynamic management of the remaining liquid volume can be achieved, preventing abnormal heating or bubble aspiration caused by liquid interruption.

[0062] The liquid supply flow status signal is acquired through a miniature flow detection structure or differential pressure sensing element installed in the liquid supply channel. When the liquid delivery is unstable or air bubbles appear in the channel, flow rate fluctuations or differential pressure changes will be detected immediately, and the main controller will analyze the signal to determine whether the liquid supply is continuous. If the continuity is interrupted or the flow is obstructed, the system will automatically reduce the drive output or temporarily interrupt atomization to ensure that the device operates within a safe range.

[0063] The atomization output efficiency signal is obtained by monitoring the feedback signal of the voltage, current, or vibration waveform of the drive circuit. The main controller estimates the atomization efficiency based on the ratio between the real-time power input and the amount of atomized liquid converted per unit time. If the efficiency continues to decline, it indicates that there may be issues such as atomizer surface contamination, changes in liquid viscosity, or poor energy transfer. The system can then perform subsequent dynamic correction operations accordingly.

[0064] The power output signal is obtained by sampling the voltage and current at the drive end. The main controller integrates and averages the sampled values ​​to obtain the actual current power output value, which is then compared with the target power. This process can be used to identify whether the drive module has aging, increased contact resistance, or energy loss problems.

[0065] In a typical embodiment, the system simultaneously acquires the above five types of signals with a sampling period of 100 milliseconds and performs smoothing filtering on the data to eliminate transient interference. The main controller sets a corresponding threshold range for each type of signal. When the system detects a temperature higher than 45°C, a liquid level lower than the safety limit, a flow rate decrease of more than 10%, or a power output deviation exceeding 5%, it generates deviation information and initiates an early warning. If the deviation persists for more than two sampling periods, the system automatically enters a dynamic adjustment phase, performing compensation operations such as power reduction, frequency correction, or time extension.

[0066] Through the above implementation method, this step realizes the real-time acquisition and fusion analysis of multi-dimensional state signals during the atomization process, which can accurately reflect the operating status of the atomization chamber and the liquid supply system, providing a reliable basis for subsequent deviation judgment and control parameter correction, thereby significantly improving the safety, stability and intelligence level of the atomization equipment.

[0067] In some embodiments, in step S5, the detection signals of temperature, liquid level, liquid supply flow, atomization efficiency and power output are compared and analyzed to determine whether each detection result deviates from the target parameter range, and dynamic control is performed when the deviation exceeds the set threshold. Indirect compensation will be implemented using the following strategies: When the test results show that the temperature of the atomizing chamber is higher than the target range or the liquid level is lower than the lower limit, it is determined that there is a risk of overheating or dry burning, and the atomization intensity is reduced, and a combination of power reduction and frequency reduction is implemented. When the atomization output efficiency is lower than the target level, the atomization intensity is increased, and adjustments are made to increase power or frequency. When the liquid supply flow is unstable, reduce the frequency and power; When the drive output power does not reach the set target, increase the drive voltage or current.

[0068] In this embodiment, after acquiring real-time data from each detection unit, the main controller first compares each detection signal with the target parameter. The system sets independent deviation tolerance thresholds for different detection quantities, such as temperature deviation ±3℃, liquid level deviation ±5%, and atomization efficiency deviation ±10%. When the detection result is within the target range, the system maintains the original control parameters unchanged; when any detection result exceeds the set threshold range, the system is determined to be in an abnormal state and immediately enters dynamic control mode.

[0069] When the temperature detection signal indicates that the temperature of the atomizing chamber is higher than the target range, the system determines that it is in an overheated state. The main controller reduces the drive voltage and frequency, weakening the vibration intensity of the atomizing plate, thereby reducing energy input and suppressing further temperature rise. If the liquid level signal is detected to be below the lower limit at the same time, the system further reduces the output power and extends the duty cycle to prevent dry burning. At this time, the atomization efficiency may decrease slightly, but the system prioritizes equipment safety and liquid stability.

[0070] When the atomization output efficiency detection signal remains below the target level, the main controller determines that the atomization intensity is insufficient. The system gradually increases the power or frequency to provide stronger driving force to the atomizing plate, thereby improving liquid disruption efficiency and restoring atomization output. If the power and frequency are close to their upper limits, the system automatically extends the atomization time to compensate for the insufficient efficiency by increasing the duration of action, thus ensuring that the atomized dosage reaches the predetermined standard.

[0071] When the liquid supply flow status signal indicates unstable flow rate or large pressure differential fluctuations, the main controller determines that the liquid supply is abnormal. At this time, the system reduces power and frequency to decrease the liquid absorption speed of the atomizing plate, thereby stabilizing the liquid flow state in the liquid supply channel. After the flow signal returns to stability, the system gradually restores the original set parameters to ensure the continuity and stability of the atomization process.

[0072] When the power output detection signal indicates that the actual power is lower than the target value, the main controller automatically increases the drive voltage or current to restore the output power to the target range. If power supply voltage fluctuations or abnormal line impedance are detected, the system records the deviation information and issues a prompt signal to remind the user to check the power supply status.

[0073] In a typical embodiment, the system is set with an upper temperature limit of 45°C, a lower liquid level limit of 20% capacity, and an atomization efficiency tolerance of ±10%. During operation, when the system detects that the temperature has risen to 46°C, the liquid level has dropped to 18%, and the atomization efficiency has dropped to 85% of the target value, the system first performs a combined adjustment of reducing power by 10% and frequency by 5%, while extending the atomization time by 5 seconds. After approximately two sampling cycles, when the temperature drops to 43°C and the efficiency recovers to the target value, the system automatically restores the power to the original setting level and records a correction log.

[0074] Through the above implementation method, this step achieves real-time adaptive adjustment of the atomization state, enabling the equipment to maintain stable output under different environmental conditions, liquid level changes, and liquid supply disturbances. This dynamic control strategy, based on the principle of "safety first, efficiency compensation," achieves a balance between energy input and liquid supply, avoiding problems such as overheating, dry burning, and decreased atomization efficiency, and significantly improving the safety, reliability, and dosage consistency of the atomization process.

[0075] Please see Figure 2 and Figure 3 As shown, in some embodiments, this application provides an intelligent atomization system for implementing intelligent atomization methods, the system comprising: Atomizing bottle 1 is used to encapsulate pre-mixed atomizing liquid. The atomizing bottle 1 is equipped with an information identification unit, which is used to store the type identifier and parameter information of the atomizing liquid. Atomizing chamber 21 is used to accommodate and fix the atomizing bottle 1; Atomizing device 24 is used to atomize the atomizing liquid under the drive of main controller 22; The main controller 22 is electrically connected to the information identification unit, the atomization generator 24, and multiple detection units in the detection unit group; The detection unit group includes a temperature detection unit, a liquid level detection unit, a liquid supply flow detection unit, an atomization efficiency detection unit, and a power detection unit, which are used to output real-time detection signals of temperature, liquid level, flow state, atomization efficiency, and power, respectively. The communication unit is used to realize wired or wireless communication between the information identification unit and the main controller 22. The communication methods include electromagnetic induction, optical identification or near-field communication. The human-computer interaction unit is used to display information about the atomizing liquid, atomization status and working mode, and to receive user input.

[0076] In some embodiments, the main controller 22 is used for: Acquire initial signals to characterize the properties of the atomizing fluid and the user's usage status; Extract atomizing fluid type information and calculate atomization target parameters based on the initial signal; Generate and issue initial control commands for atomization to drive the atomization generator 24 to work; During the atomization process, the system receives detection signals from the detection unit and performs deviation analysis. When the detected signal deviates from the target parameter range, one or more controllable parameters, such as power, frequency, or time, are selected to perform indirect compensation control.

[0077] In this embodiment, the atomizing bottle 1 adopts a sealed structure to prevent external contamination and liquid evaporation. The bottle body material is a polymer material with good chemical stability and transmission performance. The integrated information identification unit on the bottle body can store the formula number, expiration date, recommended atomization parameters, and safety restrictions of the atomizing liquid. In this embodiment, the information identification unit uses an NFC tag 11. When the atomizing bottle 1 is installed in the atomization chamber 21, the communication unit automatically reads the information through near-field sensing. The main controller 22 loads the corresponding control template accordingly, thereby ensuring the matching accuracy of different medications or functional liquids in the device.

[0078] The atomizing chamber 21 is designed as a modular structure to support and fix the position of the atomizing bottle 1, while providing a stable installation reference for the atomizing device 24. Its interior may include a liquid guiding channel and positioning clips to keep the distance and angle between the atomizing bottle 1 and the atomizing plate constant, thereby ensuring a stable gas-liquid interface and efficient vibration transmission. A condensate recovery tank may be provided at the bottom of the atomizing chamber 21 to prevent liquid accumulation from affecting the atomization effect.

[0079] The atomizing device 24 typically includes a drive circuit and an atomizing plate assembly. The main controller 22 drives the atomizing plate to vibrate at high frequency by outputting voltage, frequency, and timing signals, converting the atomized liquid into aerosol with uniform particle size. The drive circuit has a built-in constant power control unit, which can automatically adjust the output according to the target power signal of the main controller 22, thereby ensuring atomization efficiency and energy utilization.

[0080] The detection unit group is responsible for comprehensive monitoring of the system's operating status. The temperature detection unit can use a surface-mount thermistor or a MEMS temperature sensor to monitor the temperature of the atomizing plate and cavity; the liquid level detection unit measures changes in liquid level height through optical reflection or capacitive sensing; the liquid supply flow detection unit monitors the drug flow rate and channel resistance through a micro-flowmeter or differential pressure sensor; the atomization efficiency detection unit calculates the energy conversion rate by detecting the drive current waveform and vibration feedback signal; and the power detection unit obtains the actual output power through voltage and current sampling. The main controller 22 performs data fusion and deviation analysis on the above signals in each working cycle.

[0081] In this embodiment, the communication unit employs an NFC near-field communication module 23. When the device approaches or is installed in place near the atomizing bottle 1, the communication unit automatically establishes a connection, enabling bidirectional data exchange between the information identification unit and the main controller 22. This structure does not rely on external imaging or scanning devices and features strong anti-interference capabilities and a short response time.

[0082] The human-machine interface unit includes a display screen 25, LED indicator lights 26, and an input controller 27. The display screen 25 can display information such as the name of the atomizing liquid, current temperature and humidity, atomization mode, and running time in real time, and allows users to operate the device via touch, buttons, or voice commands. The LED indicator lights 26 are used to indicate whether the device is powered on. For example, users can select "gentle mode," "standard mode," or "powerful mode" on the interface, and the system will automatically load the corresponding atomization parameter set.

[0083] In a typical embodiment, after the user installs the medicine bottle containing the NFC tag 11, the communication unit automatically reads the medicine type "Medicine A" and its recommended parameters. The main controller 22 combines environmental detection signals and user mode selection to generate atomization target parameters, thereby forming initial control commands to drive the atomizing plate to work. During atomization, detection signals such as temperature, liquid level, flow, and power are fed back to the main controller 22 in real time. When low power output or decreased atomization efficiency is detected, the system automatically increases the output voltage and fine-tunes the frequency to restore the atomization effect to the optimal state; if excessively high temperature or low liquid level is detected, the power is reduced and the atomization time is extended to prevent overheating or dry burning.

[0084] Through the above implementation methods, this system achieves fully automated control of the entire process, including nebulizer liquid identification, parameter calculation, drive execution, and real-time correction. It maintains stable output under different environmental and individual usage conditions, ensuring consistent nebulized particle size and dosage. The system combines intelligent identification, safety control, and adaptive adjustment functions, significantly improving the intelligence level and clinical application reliability of nebulization equipment.

[0085] In some embodiments, this application provides a terminal, including: The memory is used to store the intelligent atomization program; A processor is used to execute the steps of the intelligent atomization method when the intelligent atomization system is used.

[0086] In some embodiments, this application provides a computer-readable storage medium that stores computer instructions. When a computer reads the computer instructions in the storage medium, the computer executes the intelligent atomization method.
