[0032] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0033] The negative pressure generator of the embodiment of the present application may be an electric piston pump, an electric vortex pump, an electric diaphragm pump, an air pump type negative pressure pump, a piezoelectric pump, etc., which is not limited in the embodiment of the present application. These negative pressure generators have heating problems to varying degrees. A piezoelectric pump is a fluid driver. It does not require an additional drive motor, but uses the inverse piezoelectric effect of the piezoelectric medium to deform the piezoelectric vibrator, and then the deformation generates a volume change in the pump chamber to achieve fluid output or uses the piezoelectric vibrator to generate fluctuations to drive the fluid to form negative pressure. The piezoelectric pump is small in size and low in noise. However, there are also some problems, such as the heating problem will be more serious than that of a traditional air pump. In one embodiment, the piezoelectric pump may be a piezoelectric ceramic pump.

[0034] Please refer to FIG1 , which is a flowchart of a control method for a breast pump according to a first embodiment of the present application.

[0035] In this embodiment, the method for controlling a breast pump may include the following steps:

[0036] Step S11: detecting the temperature of the negative pressure generator of the breast pump.

[0037] The temperature of the negative pressure generator is detected by arranging a temperature sensor on the negative pressure generator or around a position adjacent to the negative pressure generator. For example, the temperature sensor is arranged on a pump housing of the negative pressure generator or at a position around the pump housing.

[0038] Step S12: Determine whether the temperature of the negative pressure generator is greater than a preset temperature threshold.

[0039] In step S12, after determining that the temperature of the negative pressure generator is greater than a preset temperature threshold, step S13 is executed: controlling the negative pressure generator to operate in a first operating mode.

[0040] In step S12, after determining that the temperature of the negative pressure generator is less than or equal to the preset temperature threshold, step S14 is executed: the negative pressure generator is controlled to operate in a second working mode, and the output power of the negative pressure generator in the second working mode is higher than the output power of the negative pressure generator in the first working mode.

[0041] Among them, the currently detected temperature of the negative pressure generator is compared with the safety temperature threshold preset in the system: if the temperature of the negative pressure generator is greater than the preset temperature threshold, it means that the negative pressure generator may be overheating. In order to prevent damage to the equipment or affect the safety and efficiency of use, the negative pressure generator is controlled to enter the first working mode. This mode can be measures such as reducing output power, intermittent operation, or starting a cooling mechanism to reduce heat generation and ensure that the temperature remains within a safe range. If the temperature of the negative pressure generator is less than or equal to the preset temperature threshold, it indicates that the operating temperature of the equipment is normal and the working efficiency can be safely improved, then the negative pressure generator is controlled to enter the second working mode. In the second working mode, the negative pressure generator will operate at a higher output power, thereby providing stronger suction force or faster suction speed to meet the user's needs for efficient milk extraction.

[0042] In one embodiment, the controlling the negative pressure generator to operate in the first working mode includes: in a working cycle in the first working mode, controlling the negative pressure generator to operate at a first suction value in a first time period, and controlling the negative pressure generator to operate at a second suction value lower than the first suction value in a second time period; the controlling the negative pressure generator to operate in the second working mode includes: in a working cycle in the second working mode, controlling the negative pressure generator to operate at the first suction value. In the first working mode: in each complete working cycle, the system first sets a time period (first time period), during which the negative pressure generator operates at a higher first suction value to ensure efficient extraction or delivery of the medium. Subsequently, in the second time period in the same working cycle, the suction value of the negative pressure generator is reduced to a second suction value lower than the first suction value. This strategy may be intended to reduce heat accumulation from continuous high-intensity work, prevent overheating of the negative pressure generator, thereby extending the service life of the equipment and optimizing energy utilization efficiency. In the second operating mode, the vacuum generator maintains its first suction level throughout a single operating cycle. This means the device is operating at full capacity, making it suitable for scenarios requiring rapid or sustained high-efficiency operation. However, this may increase the generator's heat generation and energy consumption. This allows the control system to flexibly switch the vacuum generator's operating mode based on actual needs, temperature conditions, and energy requirements, achieving a balance between performance and heat control.

[0043] In another embodiment, controlling the negative pressure generator to operate in a first operating mode includes: controlling the negative pressure generator to operate at a first suction value during a first time period within a working cycle in the first operating mode, and suspending operation during a second time period. Controlling the negative pressure generator to operate in a second operating mode includes: controlling the negative pressure generator to operate at the first suction value during a working cycle in the second operating mode. In the first operating mode, within each complete working cycle, a time period (the first time period) is first set, during which the negative pressure generator operates normally at the set first suction value. Subsequently, during a second time period within the same working cycle, the negative pressure generator is suspended. This "intermittent operation" design is intended to reduce heat accumulation during continuous operation of the device through downtime periods, preventing overheating and saving energy. In the second operating mode, the negative pressure generator operates at full speed throughout the entire working cycle, i.e., it always operates at the first suction value, ensuring that the device can continuously provide the required suction capacity. This is suitable for scenarios requiring continuous and efficient operation, but may cause the negative pressure generator temperature to rise rapidly. By selecting and switching between these two different working modes, the system can intelligently adjust the working state of the negative pressure generator according to actual needs, heat dissipation conditions and energy consumption requirements, achieving a balanced optimization between performance and energy saving, stability and safety.

[0044] In some embodiments, upon determining that the temperature of the negative pressure generator is greater than a preset temperature threshold, controlling the negative pressure generator to operate in the first operating mode includes: upon determining that the temperature of the negative pressure generator is greater than the preset temperature threshold, controlling the breast pump's massage unit to operate during a second time period. In this embodiment, the strategy for controlling the negative pressure generator's temperature is further refined: when the system detects that the negative pressure generator's operating temperature exceeds the preset temperature threshold, the system switches to the first operating mode to prevent overheating and protect device performance and safety. The specific operation is as follows: In the original first operating mode, upon determining that the temperature is too high, in addition to maintaining the negative pressure generator at the first suction value during the first time period, a new mechanism is added: during the second time period, the negative pressure generator's operation is not only reduced or suspended (as described above), but the breast pump's massage unit is also activated or enhanced. Through this adjustment, the massage unit is utilized to distribute the user's demand for suction intensity, indirectly reducing the workload of the negative pressure generator, thereby helping to cool it down. This strategy ensures both user comfort and device safety, preventing malfunctions caused by prolonged high-temperature operation.

[0045] In some embodiments, the control method further includes setting the proportion of the first and second time periods relative to the duration of the operating cycle based on the magnitude of the first suction value, wherein the greater the first suction value, the greater the proportion of the second time period relative to the operating cycle. The above-mentioned negative pressure generator control method also includes intelligently setting the proportion of the duration of different time periods within the operating cycle: when the operating mode of the negative pressure generator is determined based on the first suction value, the system dynamically adjusts the proportion of the first and second time periods within the entire operating cycle based on the magnitude of the first suction value. The specific rule is as follows: As the first suction value increases, that is, the negative pressure generator operates at a higher suction intensity, to prevent overheating and extend the service life of the device, the system will appropriately increase the proportion of the second time period within the entire operating cycle. That is, within the same operating cycle, the time the negative pressure generator operates at high intensity (the first suction value) is reduced, while the time it is paused or operating at low power (the second time period) is increased. This design ensures that the operating temperature of the negative pressure generator is effectively controlled while maintaining the necessary suction effect, achieving an optimal balance between performance and safety, and efficiency and durability.

[0046] Please refer to FIG2 , which is a flow chart of a control method for a breast pump according to a second embodiment of the present application.

[0047] In this embodiment, after determining that the temperature of the negative pressure generator is greater than a preset temperature threshold, controlling the negative pressure generator to operate in the first operating mode includes: after determining that the temperature of the negative pressure generator is greater than the preset temperature threshold, further determining whether the current state is in the milking period based on the milk suction flow detected in real time by the breast pump; after determining that the current state is in the milking period, determining based on the milk suction flow that the current state is over before entering the first operating mode.

[0048] In this embodiment, the control method of the breast pump may specifically include the following steps:

[0049] Step S21: detecting the temperature of the negative pressure generator of the breast pump.

[0050] Step S22: Determine whether the temperature of the negative pressure generator is greater than a preset temperature threshold.

[0051] In step S22, after determining that the temperature of the negative pressure generator is greater than a preset temperature threshold, step S23 is executed: determining whether the current state is in the milking period based on the milk suction flow detected in real time by the breast pump, and after determining that the current state is in the milking period, entering the first working mode after determining that the current milking period has ended based on the milk suction flow.

[0052] In step S22, after determining that the temperature of the negative pressure generator is less than or equal to the preset temperature threshold, step S14 is executed: the negative pressure generator is controlled to operate in a second working mode, and the output power of the negative pressure generator in the second working mode is higher than the output power of the negative pressure generator in the first working mode.

[0053] In this embodiment, the temperature control strategy for the negative pressure generator has been refined. When the negative pressure generator's operating temperature exceeds a preset safety threshold, the system first considers entering the first operating mode to reduce workload and heat generation. Furthermore, this strategy takes into account the physiological characteristics of the breastfeeding process—the lethal phase (the period of rapid milk flow). The specific steps are as follows: 1. When the negative pressure generator temperature is detected to be too high, the system immediately pauses and switches to the first operating mode. 2. The system monitors the current milk flow rate in real time to determine whether the breastfeeding phase is underway. If the breastfeeding phase is underway, i.e., a period of high milk flow, the system will temporarily maintain the current operating mode until the lethal phase naturally ends, even if the negative pressure generator overheats, to ensure efficient milk extraction and avoid waste or discomfort. 3. After the lethal phase ends, the system returns the negative pressure generator to the first operating mode, reducing the operating temperature by reducing suction during a first time period or suspending operation during a second time period. This intelligent adjustment method can not only ensure effective milk suction during the mother's peak milk production period, but also effectively prevent the performance degradation or damage of the negative pressure generator caused by continuous high temperature.

[0054] Please refer to FIG3 , which is a flowchart illustrating a third embodiment of the present application for determining whether the current phase is the milk letdown phase based on the milk flow rate detected in real time by the breast pump.

[0055] In this embodiment, the step of determining whether the current phase is the milk letdown phase based on the milk flow rate detected in real time by the breast pump may specifically include:

[0056] Step S31: determining whether the real-time detected milk suction flow rate is greater than a preset flow rate threshold.

[0057] In step S31, when it is determined that the milk suction flow rate is greater than the preset flow rate threshold, step S32 is executed: determining that the current stage is the milking period.

[0058] In step S31, when it is determined that the milk suction flow rate is less than or equal to the preset flow rate threshold, step S33 is executed: determining that the current period is a non-milking period.

[0059] In this control method, flow rate changes during the milking process are monitored and determined in real time: Step S31: The system continuously monitors the actual milk flow collected by the breast pump and compares it with a preset flow threshold. If the detected milk flow rate is greater than the preset flow threshold, this indicates that the mother is in the milking phase, i.e., a state of rapid milk flow. In this case, step S32 is executed: The system determines the current state as the milking phase. During this period, the system may choose to maintain or moderately increase the operating efficiency of the negative pressure generator to ensure efficient milking, while also closely monitoring temperature changes to prevent overheating. If the detected milk flow rate is less than or equal to the preset flow threshold, the current state is considered to be the non-milking phase, i.e., a period of relatively stable or slow milk flow. Step S33 is then executed: The system determines the current state as the non-milking phase. During this phase, the negative pressure generator can be controlled according to the preset first operating mode (such as the aforementioned time-based suction adjustment or suspension). This ensures proper milking results while effectively managing heat generation and extending the service life of the device.

Specifically, after determining that the temperature of the negative pressure generator 63 is greater than the preset temperature threshold, the processor 61 further determines whether the current state is a milking phase based on the real-time milking flow rate detected by the breast pump. If the current state is a milking phase, the processor 61 determines based on the milking flow rate that the current milking phase has ended before entering the first operating mode.

[0072] The processor 61 determines whether the current stage is the milk let-down stage based on the milk suction flow detected in real time by the breast pump, including: the processor 61 obtains the real-time milk suction flow value detected by the flow monitoring unit, and determines whether the real-time detected milk suction flow is greater than a preset flow threshold; the processor 61 determines that the current stage is the milk let-down stage when the milk suction flow is greater than the preset flow threshold.
