[0002] It's well known that breast milk is the best nutrition for infants. The World Health Organization recommends breastfeeding for at least one year. However, mothers often return to work several weeks after giving birth. To ensure a timely supply of breast milk for their infants and alleviate the discomfort of breast swelling and pain caused by excessive breast milk production, mothers can use a breast pump to express breast milk. Properly storing the expressed milk ensures a continuous supply when the infant needs it.

[0003] In order to achieve the above purpose, a breast pump is usually used. The mother presses her breasts against a funnel-shaped breast shield, and negative pressure is applied by the pump unit to achieve the purpose of extracting breast milk.

[0004] However, in the related art, breast pumps are often carried by mothers, for example, worn directly in a matching bra. When the breast pump battery is low, it is inconvenient to charge it in time.

However, in the actual application of this application, this is not limiting.

[0049] Please refer to Figure 1, which is a first structural diagram of a breast pump provided by an embodiment of the present application. As shown in Figure 1, the breast pump includes a housing 1, a storage unit 2, a pump unit 3 and a breast shield 4.

[0050] The storage unit 2 is used to store milk sucked out by the breast pump, the pump unit 3 is used to generate negative pressure to suck out the milk, and the breast shield 4 is used to cover the human breast and fit the breast.

[0051] In some embodiments, the storage unit 2 includes a milk cap, a milk bowl, a milk bottle, etc., which is not limited in this application.

[0052] In some embodiments, the breast pump further comprises an energy supply module, such as a battery, which is used to provide energy to the pump unit 3 to support the operation of the pump unit 3 .

[0053] In some embodiments, in the pump unit described in the breast pump of the present application, the pump unit 3 for generating negative pressure includes but is not limited to a piezoelectric pump, a diaphragm pump, a hydraulic pump, a mechanical pump, etc., which can be directly connected to cause negative pressure inside the breast shield, or can indirectly cause negative pressure inside the breast shield by transmitting the negative pressure to a liquid barrier such as a diaphragm or an air bag; through the negative pressure, breast milk is introduced into the storage unit for storage.

[0054] In some embodiments, the breast pump includes a diaphragm, and there is a closed space between the pump unit and the diaphragm. When the breast pump is sucking milk, the pump unit sucks air in the closed space to generate negative pressure. When air is taken in, the solenoid valve opens the air hole to open the air path, and the external gas enters the closed space from the air path, so that the negative pressure is reduced and gradually returns to atmospheric pressure.

[0055] In some embodiments, the pump unit of the present application is at least partially disposed in a housing, which may also include components such as a battery, a negative pressure air circuit, a control circuit board, and a solenoid valve.

[0056] Please refer to Figure 2, which is a second structural diagram of a breast pump provided by an embodiment of the present application. As shown in Figure 2, the breast pump in Figure 2 includes a pump unit 3, a motor 5, an air hole 6 and a solenoid valve 7.

[0057] In some embodiments, the motor 5 is used to drive the pump unit 3 to work, and the solenoid valve 7 is connected to the control unit of the breast pump to control the opening and closing of the air circuit, that is, whether the air hole 6 can be ventilated to control the start and stop of the vacuum pump.

[0058] Please refer to Figure 3, which is a first flow chart of a method for controlling a breast pump provided by an embodiment of the present application. The method is applied to a breast pump. As shown in Figure 3, the method 100 for controlling a breast pump includes steps 110 to 130.

[0059] Step 110: When the breast pump is performing air intake operation, record the air intake time of the breast pump.

[0060] In some embodiments, when the breast pump is performing air intake operation, the air intake time of the breast pump is recorded in real time.

[0061] Optionally, after the control valve is opened, the breast pump starts to perform air intake operation.

[0062] In some embodiments, the breast pump includes a first timing unit. When the control valve is opened, ie, the breast pump starts to take in air, the timing unit starts to work to record the air intake time of the breast pump in real time.

[0063] Step 120: Determine the current intake volume according to the intake time.

[0064] In some embodiments, the breast pump stores a correspondence table and / or a corresponding formula between the air intake time and the current air intake volume. The current air intake volume can be obtained by looking up the table according to the air intake time, or by substituting the air intake time into the corresponding formula.

[0065] In some embodiments, step 120 includes the following steps.

[0066] (1) The current intake volume is determined according to the intake time and the channel parameters of the intake channel controlled by the control valve.

[0067] In some embodiments, the current intake volume is not only related to the intake time, but also to channel parameters of the intake channel controlled by the solenoid valve. The channel parameters include at least one of a channel cross-sectional area and a channel length, but are not limited thereto.

[0068] For example, a larger channel cross-sectional area leads to a faster air intake speed. For example, when other parameters remain unchanged, the channel cross-sectional area is 2 cm 2 The air intake speed of the breast pump will be less than the channel cross-sectional area of ​​5cm 2 The air intake speed of the breast pump.

[0069] For example, the shorter the channel length, the faster the air intake speed. For example, when other parameters remain unchanged, the air intake speed of a breast pump with a channel length of 3 cm will be greater than the air intake speed of a breast pump with a channel length of 6 cm.

[0070] Step 130: When the current air intake volume meets a preset condition, adjust a control voltage value of a control valve controlling the breast pump; wherein the control valve is used to control air intake of the breast pump.

[0071] In some embodiments, the control voltage value applied to the control valve is proportional to the magnitude of the control force applied to the control valve. When the opening degree of the control valve has not reached the limit, the greater the control voltage value applied to the control valve, the higher the opening degree of the control valve.

[0072] In some embodiments, please refer to FIG4 , which is a second flow chart of a method for controlling a breast pump provided by an embodiment of the present application. As shown in FIG4 , the method 200 for controlling a breast pump includes steps 210 to 250 .

[0073] Step 210: When the breast pump is performing milk pumping, the suction force and milk pumping time of the breast pump are recorded.

[0074] In some embodiments, the breast pump includes a second timing unit. When the pump unit applies negative pressure to the breast shield, ie, the breast pump starts to pump milk, the second timing unit starts to work to record the pumping time of the breast pump in real time.

[0075] In some embodiments, the suction force of the breast pump can be reflected as the gear position of the breast pump. The user can adjust the suction force of the breast pump by triggering a button on the breast pump shell or adjusting the gear position of the breast pump through an APP on the terminal. Therefore, the suction force of the breast pump can be obtained through the current gear position of the breast pump.

[0076] Step 220: Determine the total suction volume during the milk pumping operation according to the suction force and the milk pumping time.

[0077] In some embodiments, the total suction volume of the breast pump during operation can be determined based on the suction force and the milking time of the breast pump during operation.

[0078] In some embodiments, because the total aspirated volume may be different for different breast pump structures with the same suction force and pumping time, it is necessary to conduct multiple tests with different suction forces and different pumping times for breast pumps with different structures to determine the corresponding relationship between suction force, pumping time and total aspirated volume.

[0079] Illustratively, the test group used for testing includes: suction force 60 mmHg, inhalation time 25 minutes; suction force 60 mmHg, inhalation time 30 minutes; 60 mmHg, inhalation time 35 minutes; 65 mmHg, inhalation time 25 minutes; suction force 65 mmHg, inhalation time 30 minutes; 65 mmHg, inhalation time 35 minutes; ... suction force 100 mmHg, inhalation time 35 minutes.

[0080] In some embodiments, the corresponding relationship can be expressed as a single inspiration formula. Based on the data obtained from the above test group tests, a multiple linear regression method or a multiple nonlinear regression method is used to determine the regression parameters to establish a regression line or regression curve as a calculation formula for the suction force, milk suction time and total inspiration volume.

[0081] Exemplarily, the calculation formula is: total inhaled volume = A*(suction force)+B*(suction time)+C; wherein A, B, and C are all regression parameters.

[0082] Step 230: When the breast pump is performing air intake operation, record the air intake time of the breast pump.

[0083] For specific details, please refer to the above part of the manual, which will not be repeated here.

[0084] Step 240: Determine the current intake volume according to the intake time.

[0085] For specific details, please refer to the above part of the manual, which will not be repeated here.

[0086] Step 250: When the current air intake volume meets a preset condition, adjust a control voltage value of a control valve controlling the breast pump; wherein the control valve is used to control air intake of the breast pump.

[0087] In some embodiments, step 250 includes the following steps.

[0088] (1) When the difference between the total suction volume and the current intake volume is less than a preset difference, adjusting the control voltage value of the voltage of the control valve of the breast pump.

[0089] In some implementations, the preset difference=total inhalation volume−the current intake volume.

[0090] In the above manner, when the difference between the total suction volume and the current intake volume is smaller than the preset difference, the control voltage value of the control valve of the breast pump is adjusted, thereby achieving the purpose of saving power.

[0091] In some embodiments, step 250 includes the following steps.

[0092] (1) Obtain the preset scale factor.

[0093] (2) Determine a volume threshold according to a preset proportionality coefficient and the total inhaled volume.

[0094] (3) When the current intake volume is greater than the volume threshold, adjust the control voltage value of the voltage of the control valve of the breast pump.

[0095] In the above manner, when the current intake volume is greater than the volume threshold, the control voltage value of the control valve of the breast pump is adjusted, thereby saving power. Furthermore, the volume threshold is determined by the total intake volume, thereby ensuring that the control voltage value is adjusted after the intake process reaches a certain progress, thereby ensuring normal intake.

[0096] In some embodiments, the preset proportional coefficient has a value range of (0, 0.5], for example, 0.1 or 0.2 or 0.3 or 0.4 or 0.5.

[0097] In some embodiments, step 250 includes the following steps.

[0098] (1) Lowering the control voltage value of the control valve controlling the breast pump to a preset control voltage value.

[0099] In some embodiments, the control voltage value of the control valve of the breast pump reflects the magnitude of the control force applied to the control valve. In order to ensure the normal opening and closing of the control valve, the initial control voltage value applied to the control valve is generally higher than the opening voltage value. For example, only a voltage of 2.5V is required to open the control valve, but in reality a voltage of 5V is applied.

[0100] In this case, when the air intake process reaches a certain level, the control voltage value of the control valve controlling the breast pump is reduced to a preset control voltage value to achieve the purpose of saving electricity, but the preset control voltage value needs to be higher than the opening voltage of the control valve.

[0101] In some embodiments, step 250 includes the following steps.

[0102] When the current air intake volume meets a preset condition, a control voltage value of a voltage of a control valve of the breast pump is reduced according to an increase in the current air intake volume.

[0103] Specifically, the adjustment of the control voltage value can also be a continuous process. For example, when the current intake volume meets the preset conditions, the intake progress corresponding to the current intake volume is determined. As the intake progress increases, the control voltage value starts to decrease from the initial control voltage value as a benchmark. When the intake progress reaches 100%, the control voltage value is reduced from the initial control voltage value to the opening voltage of the control valve.

[0104] For example, assuming that the current intake volume meets the preset conditions, the intake progress corresponding to the current intake volume is determined to be 70%, the initial control voltage value is 5V, and the start-up voltage is 2.3V. After the intake progress reaches 70%, the control voltage value decreases by (5-2.3) / 30=0.09V for every 1% increase in the intake progress.

[0105] When the air intake progress reaches 100%, the negative pressure formed by the pump unit sucking air during the milk pumping operation disappears.

[0106] It can be understood that the above embodiment is an embodiment of uniform decrease, and the decrease of the control voltage value can also be a non-uniform process, for example, the decrease of the control voltage value is an inverse proportional function.

[0107] In some embodiments, reducing the control voltage value of the control valve of the breast pump to a preset control voltage value includes the following steps.

[0108] (1) Reducing the duty cycle of the PWM signal of the control valve of the breast pump to a preset duty cycle.

[0109] In some embodiments, the greater the duty cycle of the PWM signal, the greater the control voltage value. Therefore, reducing the duty cycle of the PWM signal that controls the control valve of the breast pump can reduce the control voltage value.

[0110] In some implementations, the preset duty cycle is in the range of [40%, 70%].

[0111] In some embodiments, the difference between the preset duty cycle and the initial duty cycle of the PWM signal before adjustment is greater than a preset percentage.

[0112] Exemplarily, the preset percentage is 15%, based on which the initial duty cycle is in the range of [55%, 85%].

[0113] It is understandable that if the duty cycle adjustment range is small, the energy saving effect is not obvious. Therefore, in some embodiments, the difference between the preset duty cycle and the initial duty cycle before the PWM signal adjustment is set to be greater than a preset percentage to ensure the energy saving effect.

[0114] In some embodiments, after reducing the duty cycle of the PWM signal that controls the control valve of the breast pump to a preset duty cycle, the air intake speed of the breast pump is reduced, and the method further includes:

[0115] The air intake time of the breast pump is increased from a first preset time to a second preset time.

[0116] In some embodiments, after the duty cycle of the PWM signal of the control valve of the breast pump is reduced to a preset duty cycle, the control effect of the control valve will be affected.

[0117] For example, when the duty cycle of the PWM signal is the initial duty cycle, the control valve controls the intake channel to be fully open, and the channel cross-sectional area utilization rate of the intake channel reaches 100%. When the duty cycle of the PWM signal is reduced to the preset duty cycle, the intake channel is partially open, and the channel cross-sectional area utilization rate of the intake channel is only 80%. At this time, the intake time needs to be increased.

[0118] In some embodiments, the method further comprises:

[0119] The second preset time is determined according to a difference between an initial duty cycle and the preset duty cycle, and the first preset time.

[0120] In some implementations, the initial duty cycle is the duty cycle of the PWM signal before the duty cycle decreases to a preset duty cycle.

[0121] In some embodiments, the second preset time is a minimum intake time for completely releasing the gas, which is calculated based on the difference between the initial duty cycle and the preset duty cycle, and the first preset time.

[0122] In some embodiments, the decrease in intake efficiency can be determined based on the difference between the initial duty cycle and the preset duty cycle, and the total amount of intake air can be determined based on the first preset time. Therefore, a new minimum intake time, i.e., the second preset time, can be calculated based on the total amount of intake air and the decrease in intake efficiency.
