[0002] Existing breast pump devices typically consist of a breast shield, a negative pressure generating device, a control system, and a milk collection device. They generally use a constant-speed motor to drive a diaphragm pump, generating a fixed negative pressure value. The negative pressure is then periodically released through a solenoid valve, forming a suction and release cycle. However, there are issues with the pump voltage being unadjustable or only adjustable in stages at certain settings. The negative pressure accumulates only over a single period of time, lacking stepless adjustment of the pump voltage and a single negative pressure rate.

[0003] However, the fixed negative pressure value obtained by controlling the pump drive time and valve degassing time of breast pumps is often due to manufacturing errors, resulting in some differences between each instrument and the set value.

Detailed Implementation

[0019] 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.

[0020] like Figure 1 As shown, Figure 1 This is an architectural diagram of a dynamic pressure regulation control system 100 for a breast pump provided in an embodiment of the present invention. The dynamic pressure regulation control system includes a dynamic pressure regulation control device 600, a server 101, and a smart breast pump 102. The dynamic pressure regulation control device 600 further includes a first acquisition module, which can be used to acquire operating status data of the breast pump in a preset mode, including driving voltage data of the negative pressure mechanism and preset negative pressure data in the preset mode; a first determination module, which can be used to determine the current negative pressure data of the breast pump through an air pressure detection device; a first processing module, which can be used to compare the current negative pressure data with the preset negative pressure data in the preset mode for judgment processing to determine a negative pressure deviation parameter; and a first adjustment module, which can be used to adjust the driving voltage data of the negative pressure mechanism in the preset mode based on the negative pressure deviation parameter, and control the negative pressure mechanism to perform corresponding start-stop operations according to the suction maintenance strategy of the breast pump in the preset mode.

[0021] Specifically, the aforementioned intelligent breast pump refers to a smart breast pump device applied during the breast milk extraction process. It may include components such as a breast pump cup, air pump, solenoid valve, controller (MCU), pressure sensor, power module, and related electronic control units. Specifically, this breast pump can achieve periodic changes in negative pressure suction within the cavity by driving the pump and opening / closing the valve, simulating the infant's sucking process and improving breast milk secretion efficiency. It is understood that the aforementioned breast pump can be physically connected to a dynamic pressure regulation control device and receive voltage adjustment commands and suction / release rhythm configurations output by this control device to achieve personalized milk extraction rhythm control.

[0022] The aforementioned operational status data can be a quantitative identifier describing the current working state of the breast pump, including but not limited to the driving voltage data and preset negative pressure data of the negative pressure mechanism in the preset mode. Specifically, the voltage and negative pressure data can be acquired in real time through an internal acquisition module, such as voltage divider + MCU ADC sampling, or a built-in air pressure sensor, or directly based on preset parameters.

[0023] More specifically, the voltage data mentioned above can refer to the actual driving voltage supplied to the air pump in the breast pump. This voltage data can be steplessly adjusted by adjusting the voltage regulation module through the PWM control signal output by the MCU. The acquisition module can reduce the voltage to the analog input range that the MCU can accept through the voltage divider resistor and sample it in real time through the ADC port. It should be noted that the voltage data mentioned above is calibrated and converted into the pump end voltage value inside the system. The output power of the air pump during operation can be determined by adjusting the voltage data mentioned above, which ultimately affects the negative pressure formation speed and the final suction strength in the cavity.

[0024] The aforementioned negative pressure data can refer to the negative change in air pressure value inside the cavity of the aforementioned intelligent breast pump relative to atmospheric pressure. Generally, the aforementioned negative pressure data can be collected by air pressure sensors in the cavity or pipeline, and the collected pressure value is converted into a digital signal and sent to the corresponding MCU for processing.

[0025] The suction strength mentioned above can be used to reflect the strength of the negative pressure effect generated by the breast pump during the suction phase. The breast pump's dynamic pressure adjustment control system can calculate the target suction strength value to be adjusted by comparing and interpolating the preset suction strength levels with a certain range of voltage and negative pressure thresholds, combined with the current actual data. It is understood that the suction strength not only affects the user's breast pumping experience comfort, but also relates to the pump's operating efficiency and the effect of breast milk drainage. Furthermore, the pump voltage can be finely adjusted by the PWM duty cycle to achieve delicate and dynamically variable suction control.

[0026] The aforementioned suction maintenance time can be the length of time between when the breast pump maintains suction and when it resumes deflating during one suction-release cycle. It should be noted that during the aforementioned suction maintenance time, the breast pump's dynamic pressure adjustment control system can maintain negative pressure by continuously keeping the solenoid valve closed. The duration can be dynamically adjusted based on the user-defined usage mode and current negative pressure data feedback. For example, if the negative pressure in the cavity decays quickly, the breast pump's dynamic pressure adjustment control system will shorten the maintenance time to avoid weak suction; conversely, it will extend the maintenance time to enhance the stimulation effect.

[0027] By adjusting this parameter, the device can simulate different infant sucking rhythms to meet individual needs.

[0028] The aforementioned adsorption-desorption cycle refers to the total time required to complete one full adsorption and degassing process, comprising three phases: the inhalation phase, the maintenance phase, and the degassing phase. It should be noted that the length of this adsorption-desorption cycle can be influenced by both the suction intensity and the suction maintenance time, for example: The air pump is started by a PWM control signal, the pump voltage rises rapidly, and negative pressure is established in the cavity. Maintenance phase: The pump stops, the solenoid valve remains closed, and the cavity maintains a stable negative pressure; Degassing phase: The solenoid valve is opened, and the cavity pressure is quickly restored, forming a complete "suction-release" cycle.

[0029] In one possible embodiment, the following can be employed: Figure 2 The following describes a voltage regulation control system architecture. The MCU, as the core control unit, outputs a first PWM signal to the voltage regulation module to control its output voltage. The voltage is then fed back to the acquisition module and transmitted to the MCU as an analog signal, forming a voltage closed-loop regulation path. Simultaneously, the MCU outputs a second PWM signal to control the start and stop of the air pump. The suction build-up process is controlled by adjusting the duty cycle of the second PWM. After the suction phase is complete, the MCU outputs a switching signal to the solenoid valve to release the negative pressure. It also collects negative pressure data from the chamber using a pressure sensor as a digital signal feedback input to help determine whether the suction maintenance time has been reached. This dynamically adjusts the suction-release cycle and achieves precise management of the adsorption start-stop function. This structure is consistent with the aforementioned embodiment, realizing the linkage control of voltage closed-loop drive, suction intensity control, and valve release action, possessing high feedback adaptability and rhythm regulation flexibility.

[0030] like Figure 3 As shown, Figure 3 This is a flowchart of a dynamic pressure control method for a breast pump provided in an embodiment of the present invention. The dynamic pressure control method for a breast pump includes the following steps: 301. Obtain the operating status data of the breast pump in the preset mode.

[0031] In this embodiment of the invention, the above-mentioned dynamic pressure regulation control method for breast pumps can be applied to a dynamic pressure regulation control system for breast pumps. The dynamic pressure regulation control system for breast pumps has functions such as dynamic pressure regulation data processing, dynamic pressure regulation data transmission and reception, and dynamic pressure regulation data memory storage. It can be built based on a server or server cluster. The server or server cluster can be an electronic device with dynamic pressure regulation data processing capabilities.

[0032] The aforementioned breast pump refers to an intelligent breast pump device used in the breast milk extraction process. It may include components such as a breast pump cup, air pump, solenoid valve, controller (MCU), pressure sensor, power module, and related electronic control units. Specifically, this breast pump can achieve periodic changes in negative pressure suction within the cavity by driving the pump and opening / closing the valve, simulating the infant's sucking process and improving breast milk secretion efficiency. It is understood that the aforementioned breast pump can be physically connected to a dynamic pressure regulation control device and receive voltage adjustment commands and suction / release rhythm configurations output by this control device to achieve personalized milk extraction rhythm control.

[0033] The aforementioned operational status data can be quantitative indicators used to describe the current working status of the breast pump, including but not limited to voltage and negative pressure data. Specifically, the voltage and negative pressure data can be acquired in real time through internal acquisition modules, such as voltage divider + MCU ADC sampling, or a built-in pressure sensor.

[0034] More specifically, the voltage data mentioned above can refer to the actual driving voltage supplied to the air pump in the breast pump. This voltage data can be steplessly adjusted by adjusting the voltage regulation module through the PWM control signal output by the MCU. The acquisition module can reduce the voltage to the analog input range that the MCU can accept through the voltage divider resistor and sample it in real time through the ADC port. It should be noted that the voltage data mentioned above is calibrated and converted into the pump end voltage value inside the system. The output power of the air pump during operation can be determined by adjusting the voltage data mentioned above, which ultimately affects the negative pressure formation speed and the final suction strength in the cavity.

[0035] The aforementioned negative pressure data can refer to the negative change in air pressure value inside the cavity of the aforementioned intelligent breast pump relative to atmospheric pressure. Generally, the aforementioned negative pressure data can be collected by air pressure sensors in the cavity or pipeline, and the collected pressure value is converted into a digital signal and sent to the corresponding MCU for processing.

[0036] 302. Determine the current negative pressure data of the breast pump using an air pressure detection device.

[0037] In this embodiment of the invention, the above-mentioned dynamic pressure regulation control system for the breast pump acquires the voltage data at the output end of the breast pump and the real-time negative pressure data inside the cavity through the acquisition module and the air pressure sensor, and inputs the above-mentioned operating status data to the MCU for analysis and processing.

[0038] The MCU has multiple preset milk pumping modes, each corresponding to a different voltage and negative pressure threshold range. The aforementioned dynamic voltage regulation control system of the breast pump compares the current voltage and negative pressure data with the target threshold of the selected mode, calculates the voltage deviation and negative pressure deviation, and determines the voltage adjustment amount and negative pressure response characteristics based on the deviation value.

[0039] Based on this, the MCU dynamically generates the suction intensity value to be set for the current cycle and the corresponding suction duration. Therefore, the entire suction control process, combined with real-time data feedback, has a high degree of adaptability and fine adjustment capability.

[0040] 303. Compare the current negative pressure data with the preset negative pressure data in the preset mode to determine the negative pressure deviation parameter.

[0041] In this embodiment of the invention, the aforementioned adsorption-desorption cycle refers to the total time required to complete one complete adsorption and degassing process, including three stages: an adsorption stage, a maintenance stage, and a degassing stage. It should be noted that the length of the aforementioned adsorption-desorption cycle can be influenced by both the suction intensity and the suction maintenance time, for example: The air pump is started by a PWM control signal, the pump voltage rises rapidly, and negative pressure is established in the cavity. Maintenance phase: The pump stops, the solenoid valve remains closed, and the cavity maintains a stable negative pressure; Degassing phase: The solenoid valve is opened, and the cavity pressure is quickly restored, forming a complete "suction-release" cycle.

[0042] In one possible embodiment, after obtaining the current suction strength and suction duration, the above-mentioned breast pump dynamic pressure control system dynamically calculates the suction and release cycle of the breast pump in the MCU through internal logic.

[0043] Specifically, the aforementioned dynamic pressure regulation control system for the breast pump can determine the working voltage parameters of the air pump and its continuous running time based on the suction strength. When the suction strength is high, the duty cycle of the corresponding first PWM is increased, the air pump voltage rises, and the drive time is shortened accordingly to avoid overstimulation. At the same time, the length of time the solenoid valve remains closed after the air pump stops is determined based on the suction maintenance time, i.e., the negative pressure maintenance time.

[0044] Understandably, the MCU, in conjunction with the deflation time window set in the aforementioned breast pump dynamic pressure control system, comprehensively generates a complete suction and deflation cycle structure, including the time parameters of the suction phase, negative pressure holding phase, and deflation release phase, and drives the air pump and solenoid valve to perform rhythmic start and stop control in units of this cycle.

[0045] 304. Based on the negative pressure deviation parameter, adjust the driving voltage data of the negative pressure mechanism in the preset mode, and control the negative pressure mechanism to perform corresponding start and stop operations according to the suction maintenance strategy of the breast pump in the preset mode.

[0046] In this embodiment of the invention, after determining the current suction and release cycle of the breast pump, the above-mentioned dynamic pressure regulation control system for the breast pump performs phased control and management of the suction start and stop function according to the cycle. For example, according to the time parameter of the suction and release cycle, the MCU outputs a second PWM control signal to drive the air pump to power on during the suction phase, and simultaneously outputs a first PWM signal to adjust the pressure regulation module so that the pump input voltage meets the requirements of the corresponding suction strength and quickly establishes a negative pressure environment in the cavity.

[0047] At this point, the MCU controls the solenoid valve to remain closed to ensure no leakage of negative pressure. After entering the maintenance phase, the MCU stops the second PWM output, the air pump is powered off, and the cavity maintains the predetermined negative pressure; the solenoid valve remains closed to maintain the suction force continuously; when the maintenance time reaches the set value, the MCU outputs a high-level switching signal to the solenoid valve, driving the solenoid valve to open and release the gas in the cavity, completing a full suction and discharge process.

[0048] Therefore, the aforementioned dynamic pressure control system for breast pumps will adjust the rhythm and start / stop control parameters for the next cycle by combining new voltage data and negative pressure feedback after each cycle.

[0049] In this embodiment of the invention, the operating status data of the current breast pump is collected, including voltage data and negative pressure data. Based on the voltage and negative pressure data, the corresponding suction strength and suction duration are determined. The suction-release cycle of the breast pump is determined according to the suction strength and suction duration. The suction-release cycle is then used to control and manage the suction start-stop function of the current breast pump. By collecting and adjusting the voltage and negative pressure data of the breast pump through the above method steps, the suction-release cycle can be dynamically adjusted and matched according to the operating status of the breast pump. The suction start-stop function of the device is managed and controlled according to the suction-release cycle. The addition of negative pressure value feedback to identify the opening of the dynamically adjusting valve makes the pressure control more precise and flexible.

[0050] Optionally, in the step of obtaining the operating status data of the breast pump in the preset mode, the driving voltage data and preset negative pressure data of the air pump in the current preset mode can be determined based on the parameter setting set of the air pump in the preset mode; based on the preset negative pressure data, the opening and closing duration of the solenoid valve can be determined so that the breast pump can generate the preset negative pressure data.

[0051] In embodiments of the present invention, it can be achieved through, as follows: Figure 2 The system architecture shown is explained below. The voltage signal of the breast pump is acquired in real time via a data acquisition module, which consists of a voltage divider resistor network and an analog-to-digital converter (ADC) interface for the MCU. The pump drive voltage output from the voltage regulation module is divided to a range of analog levels acceptable to the MCU, then periodically sampled by the ADC and converted into voltage data, which is input to the control logic to determine the pump drive status and suction adjustment accuracy.

[0052] Meanwhile, the negative pressure value inside the breast pump is continuously detected by the air pressure sensor installed in the breast pump cavity, and the pressure data is transmitted to the MCU in the form of a digital signal to determine whether the current suction force meets the preset value.

[0053] The aforementioned dynamic pressure regulation control system for breast pumps processes the voltage and negative pressure data as unified operating status data, which is then used to dynamically generate control parameters for suction strength, suction duration, and suction-release cycle. This improves the adaptability and comfort of the breast pump in different individual usage scenarios and solves the problems of coarse adjustment and delayed feedback in traditional breast pumps.

[0054] Optionally, the step of determining the current negative pressure data of the breast pump through the air pressure detection device further includes: collecting pressure data of the negative pressure chamber of the breast pump through an air pressure sensor, determining the pressure signal of the negative pressure chamber in real time; converting the pressure signal into a digital signal according to the digital-to-analog conversion; and determining the current negative pressure data of the breast pump based on the digital signal.

[0055] In this embodiment of the invention, the aforementioned voltage threshold can be a pump drive voltage reference range set in a preset mode to achieve the target suction strength. Generally, this voltage threshold can be used to guide the dynamic pressure regulation control system of the breast pump to determine whether the currently collected pump voltage data is within a reasonable operating range. It is understood that the higher the voltage, the stronger the pump suction. Therefore, the voltage range of the pump can be limited according to the suction requirements in the preset mode, thereby achieving the purpose of setting the voltage threshold by considering the pump model and customer needs, and thus obtaining the desired suction curve.

[0056] The aforementioned negative pressure threshold refers to the negative pressure reference value or reference range required to be maintained in the cavity of the breast pump in order to achieve the suction effect of a certain preset breast pumping mode. Generally speaking, it can be set according to the user's comfort needs and the specific infant sucking characteristics that need to be simulated, and is used to dynamically determine whether the cavity of the breast pump has reached an effective suction state.

[0057] The aforementioned voltage adjustment data can be the deviation value calculated by comparing real-time voltage data with the voltage threshold in the corresponding mode, and used to provide feedback to adjust the PWM control parameters. Specifically, the aforementioned breast pump dynamic voltage regulation control system can adjust the duty cycle of the first PWM through the aforementioned voltage adjustment data, thereby driving the voltage regulation module to boost the voltage until the output voltage approaches the aforementioned voltage threshold.

[0058] The aforementioned negative pressure adjustment data refers to the deviation obtained by comparing real-time negative pressure data with a preset negative pressure threshold. It is used to guide the control strategy of the solenoid valve and the setting of the suction maintenance time. Similarly, the aforementioned breast pump dynamic pressure control system can use the aforementioned negative pressure adjustment data to extend the suction phase time or shorten the deflation interval to promote further accumulation of negative pressure.

[0059] In one possible embodiment, after acquiring the current voltage and negative pressure data of the breast pump, the aforementioned dynamic pressure control system compares them with the reference thresholds in the selected preset breast pumping mode to dynamically correct the current suction output state. Specifically, the aforementioned dynamic pressure control system has multiple preset breast pumping modes pre-stored in the database. Each mode defines a set of voltage and negative pressure thresholds to meet the suction strength and suction duration required under the corresponding conditions.

[0060] When the real-time voltage and negative pressure data collected by the aforementioned breast pump dynamic voltage regulation control system are lower or higher than their corresponding thresholds, the aforementioned breast pump dynamic voltage regulation control system calculates two sets of deviation values ​​and generates voltage adjustment data and negative pressure adjustment data. It then controls the voltage regulation module (DCDC circuit) to increase or decrease the voltage by adjusting the duty cycle of the first PWM. By judging the negative pressure build-up speed or release delay, it guides the system to adjust the opening time or cycle interval of the solenoid valve to generate suction strength and suction maintenance time that are adapted to the current user state.

[0061] Based on the two sets of adjustment data mentioned above, the PWM control parameters and valve control logic to be output in the current cycle are dynamically calculated to ensure that the breast pump can maintain the optimal suction rhythm and experience under different users and different usage stages.

[0062] Optionally, the step of comparing the current negative pressure data with the preset negative pressure data in the preset mode to determine the negative pressure deviation parameter further includes: if the current negative pressure data is greater than the preset negative pressure data in the preset mode, then determining the reduction value of the PWM duty cycle of the air pump based on the difference between the current negative pressure data and the preset negative pressure data in the preset mode; if the current negative pressure data is less than the preset negative pressure data in the preset mode, then determining the increase value of the PWM duty cycle of the air pump based on the difference between the current negative pressure data and the preset negative pressure data in the preset mode; and determining the negative pressure deviation parameter used to adjust the drive voltage based on the reduction value and the increase value of the PWM duty cycle.

[0063] In this embodiment of the invention, the duty cycle of the PWM signal can refer to the proportion of the high-level duration in one cycle of the pulse width modulation signal output by the MCU, used to determine the amplitude of the output voltage of the voltage regulation module. In this embodiment, the MCU can dynamically adjust the duty cycle of the first PWM signal according to the voltage adjustment data, for example, from 60% to 75%, to increase the output voltage of the voltage regulation module and drive the air pump to output a higher suction strength.

[0064] The target suction strength mentioned above can be the ideal suction level calculated by the dynamic pressure regulation control system of the breast pump based on the current milk pumping mode requirements and the voltage output value after feedback adjustment. It is usually positively correlated with the negative pressure of the cavity. Specifically, the PWM duty cycle can be converted into pump drive voltage through the calibrated voltage-suction mapping curve, and then mapped into negative pressure output to form the corresponding suction strength parameters.

[0065] The aforementioned solenoid valve switching time slot refers to the time window during which the solenoid valve is in the open state within one suction and discharge cycle. This is used to release the negative pressure in the cavity and end the suction effect. Generally, the length of the switching time slot can be determined by the aforementioned negative pressure adjustment data. For example, when the actual negative pressure does not reach the target value, the aforementioned breast pump dynamic pressure regulation control system will shorten the venting time slot or delay venting. When the negative pressure is too high, the aforementioned breast pump dynamic pressure regulation control system will open the valve earlier or extend the venting time to alleviate the discomfort caused by excessive suction.

[0066] The aforementioned target suction maintenance time refers to the period during which the breast pump's dynamic pressure control system maintains the solenoid valve closed and sustains suction after reaching the target negative pressure within a suction-release cycle. This timeframe can be calculated by working backwards from the deflation time slot data and is dynamically generated based on user mode settings and real-time feedback. For example, it can be set to 1.5 seconds in standard mode and reduced to 0.8 seconds in gentle mode. The breast pump's dynamic pressure control system can dynamically adjust the maintenance time according to the negative pressure build-up rate and depressurization requirements to meet the comfort requirements of users with different physical conditions regarding suction maintenance.

[0067] In one possible embodiment, the aforementioned breast pump dynamic pressure regulation control system corrects the current suction state using the voltage adjustment data and negative pressure adjustment data. Specifically, the system dynamically calculates the PWM signal duty cycle required by the air pump using the voltage adjustment data, and adjusts the drive voltage output by the voltage regulation module accordingly. Then, the system determines the target suction intensity to be applied based on the output voltage value corresponding to the duty cycle. Simultaneously, the system calculates the solenoid valve switching time slot required for air pump deflation control based on the aforementioned negative pressure adjustment data, and sets the corresponding target suction maintenance time accordingly, thereby completing the adaptive adjustment of the entire suction control rhythm.

[0068] In another possible embodiment, the above-mentioned breast pump dynamic pressure control system collects the current negative pressure data of the negative pressure chamber in real time through an air pressure sensor, compares the data with the preset negative pressure data in the preset mode, calculates the deviation between the two, and determines the deviation parameter to be used for adjustment based on the deviation value.

[0069] Specifically, when the detected negative pressure data is greater than the preset negative pressure data, it indicates that the actual suction strength is higher than the target level, which may cause user discomfort or overstimulation. Therefore, the corresponding PWM duty cycle reduction value can be calculated based on the difference between the two values ​​to reduce the output power of the air pump, thereby reducing the suction strength.

[0070] Conversely, if the current negative pressure data is less than the preset negative pressure data, it indicates that the current suction power is insufficient and the stimulation effect is poor. In this case, the PWM duty cycle increase value can be calculated based on the difference to improve the air pump's driving capability and bring the suction power back to the set range.

[0071] After calculating the increase or decrease value, a normalized negative voltage deviation parameter is further formed based on the duty cycle adjustment value. This parameter serves as the input basis for subsequent drive voltage adjustment, ensuring that the PWM signal output by the voltage regulation module can dynamically respond to changes in negative voltage and achieve closed-loop control.

[0072] Optionally, in the step of comparing and judging the current negative pressure data with the preset negative pressure data in the preset mode to determine the negative pressure deviation parameter, the negative pressure mechanism includes an air pump, and further includes: acquiring the analog signal voltage value of the acquisition module, comparing the analog signal voltage value with the drive voltage data in the preset mode to determine the first PWM value; and determining the second PWM value of the air pump under the current negative pressure data based on the first PWM value.

[0073] In this embodiment of the invention, the first PWM value can be used to drive the voltage regulation module to output drive voltage data, and the second PWM value can be used to adjust the start and stop actions of the air pump under the current negative pressure data.

[0074] Based on the collected current negative pressure data and target preset negative pressure value, the aforementioned breast pump dynamic pressure control system can adjust the air pump drive voltage through PWM signal control logic to achieve more refined pressure control. Specifically, it acquires the first PWM value set in the preset mode, which is used to drive the pressure regulating module to output reference drive voltage data, serving as the initial voltage control quantity required for the air pump to operate under standard conditions.

[0075] Subsequently, the first PWM value is used as a reference signal, and combined with the real-time negative pressure data collected by the current air pressure detection device, it is determined whether the current pump drive is sufficient to meet the target suction output requirement: If the negative pressure data deviates from the preset range (e.g., is too low), the system adjusts the duty cycle based on the negative pressure deviation parameter and the first PWM value to generate a second PWM value. This second PWM value is the corrected control signal, used to drive the voltage regulation module to generate an actual output voltage adapted to the current operating conditions. It should be noted that the adjustment range of the second PWM value can be proportional to the magnitude of the deviation.

[0076] Through the above methods and steps, the intelligent breast pump can respond to changes in the negative pressure of the cavity in real time and dynamically adjust the PWM control signal, thereby achieving closed-loop regulation of the pump drive voltage and avoiding the problem of unstable suction output due to fluctuations in operating conditions or insufficient negative pressure.

[0077] This embodiment introduces the adjustment logic of "first PWM value feedback second PWM value" and dynamically generates PWM signal control quantity based on negative pressure feedback data, realizing precise control of the output voltage of the voltage regulation module. Compared with the traditional static PWM setting method, this solution can adapt to the suction deviation caused by different user physiques, pump wear conditions or differences in breast cavity volume, ensuring that the breast pump can stably output the target suction strength in various usage scenarios.

[0078] Optionally, in the steps of adjusting the drive voltage data of the negative pressure mechanism in the preset mode based on the negative pressure deviation parameter, and controlling the negative pressure mechanism to perform corresponding start-stop operations according to the suction maintenance strategy of the breast pump in the preset mode, the method further includes determining the target drive voltage data of the air pump based on the negative pressure deviation parameter; determining the target suction intensity of the air pump based on the target drive voltage data; determining the target suction maintenance time of the air pump based on the suction maintenance strategy of the breast pump in the preset mode; and controlling the start and stop times of the air pump and the opening and closing timing of the solenoid valve according to the target suction intensity and the target suction maintenance time.

[0079] In embodiments of the present invention, the aforementioned negative pressure mechanism may include, but is not limited to, an air pump and a solenoid valve.

[0080] The aforementioned voltage parameter can be the specific voltage value required to drive the corresponding air pump to achieve the set suction intensity under a predetermined preset mode. Generally, this can be obtained by adjusting the duty cycle of the first PWM through the MCU, thereby controlling the output of the DC boost circuit. It should be noted that this voltage parameter is not a fixed value, but can dynamically change according to the user's suction needs. For example, a strong suction mode requires an output of 10.5V, while a gentle suction mode may only require 8.0V.

[0081] The aforementioned working time refers to the continuous operation time of the air pump during each suction phase. The working time can be determined by the suction strength and the size of the breast pump's inner cavity. Generally, under a low suction setting, the pump may only need to run for 0.5 seconds to establish the target negative pressure, while under a high suction setting, it may need to run for more than 1.2 seconds. Therefore, the aforementioned dynamic pressure regulation control system for the breast pump can determine the working time of the air pump based on data such as the current size of the breast pump's inner cavity and the suction strength.

[0082] The aforementioned time interval between sucking and releasing can be the transitional waiting period between the completion of one sucking and releasing cycle of the breast pump and the start of the next cycle. It can be understood that the natural pauses and breathing adjustments of an infant during sucking can be simulated by setting the aforementioned time interval between sucking and releasing.

[0083] The aforementioned target drive voltage data can refer to the new voltage control value obtained by the breast pump dynamic voltage regulation control system after detecting a deviation between the current negative pressure and the preset negative pressure, based on the PWM duty cycle adjustment value (increase or decrease) corresponding to the negative pressure deviation parameter, and correcting the original preset drive voltage.

[0084] The aforementioned target suction strength can refer to the suction strength value that the pump can generate in the negative pressure chamber under the voltage level, estimated or measured based on the electrical characteristic curve of the pump after determining the target drive voltage data.

[0085] The aforementioned target suction duration can refer to the time interval during which the suction is maintained at that intensity after the target suction strength is determined, based on the preset suction maintenance strategy currently in operation of the breast pump (such as breast milk stimulation mode, deep suction and slow release mode, etc.), combined with the suction strength and user habits.

[0086] In one possible embodiment, the aforementioned breast pump dynamic pressure regulation control system employs a closed-loop control strategy based on negative pressure feedback to finely adjust the drive voltage of the air pump. Specifically, the current negative pressure data within the negative pressure chamber of the breast pump is acquired in real time via an air pressure sensor and compared with the target negative pressure value under the current preset mode to calculate the negative pressure deviation parameter.

[0087] After obtaining this negative pressure deviation parameter, the above-mentioned dynamic pressure regulation control system for the breast pump corresponds to two adjustment strategies based on its positive and negative directions: If the current negative pressure is lower than the target value, the control system calculates an increase in the PWM duty cycle based on the magnitude of the deviation. If the current negative pressure is higher than the target value, a PWM duty cycle reduction value is calculated.

[0088] The aforementioned dynamic pressure regulation control system for the breast pump then adds or cancels this increase or decrease value to the current base PWM duty cycle value to form a new PWM control parameter, which serves as the updated PWM duty cycle. For example, if the original duty cycle was set to 70%, and the current negative pressure is insufficient and suction needs to be increased, the control system will add a +5% duty cycle increase value to generate a new duty cycle of 75%; if the suction is too strong, it will subtract 3% from 70%, updating it to 67%.

[0089] The updated PWM duty cycle is used to drive the voltage regulation module, thereby adjusting the output voltage in real time and forming new target drive voltage data. This target voltage is the precise control voltage required to adapt to the current negative pressure state, used to drive the air pump to operate, enabling it to respond quickly to changes in negative pressure and restore and maintain within the target suction range.

[0090] The PWM adjustment process can be continuously iterated by the aforementioned breast pump dynamic voltage regulation control system until the current negative pressure is stably maintained within the target negative pressure range, thereby achieving dynamic closed-loop update control of the drive voltage.

[0091] Optionally, the steps of controlling the start and stop timing of the air pump and the start and stop timing of the solenoid valve according to the target suction intensity and the target suction maintenance time further include, during the suction phase of the suction cycle, controlling the air pump to start according to the target drive voltage and run for the target working time and then stop, based on the target suction intensity; during the suction maintenance phase, controlling the air pump to stop and controlling the solenoid valve to remain closed to maintain the negative pressure in the cavity; during the discharge phase, controlling the solenoid valve to open for the target opening time to release the cavity pressure and complete one adsorption cycle.

[0092] In embodiments of the present invention, it can be achieved through, as follows: Figure 4 , Figure 5 The voltage and air pressure curves shown in the diagrams illustrate the different modes. When the dynamic pressure control system of the breast pump detects the current suction and release cycle, the controller MCU outputs a first PWM signal when it detects the entry into the suction stage. This drives the pressure adjustment module to increase the pump input voltage to the voltage parameter corresponding to the suction strength. The second PWM signal then activates the pump drive circuit, causing the air pump to start and run continuously until the set suction working time is reached. This quickly establishes the target negative pressure environment in the cavity, achieving the suction action.

[0093] After the above actions, when entering the air release stage of the suction and release cycle, the above-mentioned breast pump dynamic pressure regulation control system shuts off the second PWM signal to stop the air pump from running. At the same time, the MCU outputs a high-level signal to the solenoid valve control terminal to turn on the solenoid valve, release the negative pressure in the cavity, and complete one suction and release action.

[0094] By following the above steps, the suction voltage, deflation duration, and start-stop sequence can be dynamically adjusted based on the suction and deflation rhythm and real-time feedback data, ensuring that the breast pump can stably and efficiently complete each round of suction and deflation, thus creating a natural rhythm and appropriate intensity suction behavior curve.
