[0002] With more and more mothers demanding more freedom and convenience in breastfeeding, smart automatic breast pumps are becoming widely used. Existing smart breast pumps simulate a baby's sucking process by periodically driving a motor-driven air pump to pump air and a valve to release air, thereby achieving automatic milk extraction. During a simulated sucking cycle, the air release valve remains closed, and then the air pump continuously pumps air to a certain negative vacuum level, allowing the suction nozzle covering the breast to generate a certain suction force to extract the breast milk. This simulated sucking process is inefficient, making it difficult to completely extract the breast milk, and can even lead to blocked breast milk flow, resulting in a poor user experience.

[0023] In order to make the purpose, technical solutions and advantages of the present application more apparent, the following is a detailed description of example embodiments of the present application with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the example embodiments described herein. Based on the embodiments of the present application described in this application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of this application.

[0024] First, refer to Figure 1 A drive control device for a breast pump according to an embodiment of the present application is described. Figure 1 FIG. 1 shows a schematic structural block diagram of a drive control device 100 for a breast pump according to an embodiment of the present application. Figure 1 As shown, a drive control device 100 for a breast pump includes an air pump module 110, an air valve module 120, and a control module 130. The breast pump includes a milk suction component (not shown), which is used to cover the breast to form an enclosed space. The control module 130 is configured to control the air pump module 110 to evacuate the enclosed space within a first time interval to achieve an air suction cycle; the control module 130 is configured to control the air valve module 120 to deflate the enclosed space within a second time interval to achieve a deflation cycle. One air suction cycle and one deflation cycle constitute a simulated sucking cycle. The control module 130 is also configured to control the operation of the air pump module 110 or the air valve module 120 during a simulated sucking cycle to cause the milk suction component to vibrate.

[0025] In the embodiment of the present application, the control module 130 controls the operation of the air pump module 110 or the air valve module 120 during a simulated sucking cycle. Since the function of the air pump module 110 is to extract air from the enclosed space formed by the milk suction component covering the breast, and the function of the air valve module 120 is to deflate the enclosed space formed by the milk suction component covering the breast, the control module 130 controls the air pump module 110 or the air valve module 120 to cause a certain change in the gas pressure in the enclosed space formed by the milk suction component covering the breast. This change causes the milk suction component to vibrate, thereby achieving a vibration massage effect during the milk suction process, realizing a massage-like dredging of the entire breast during the milk suction process, which can not only improve milk suction efficiency, but also reduce the blockage of milk discharge from the breast, thereby improving user experience.

[0026] In one embodiment of the present application, the control module 130 controls the operation of the air pump module 110 or the air valve module 120 during a simulated sucking cycle to cause the sucking component to vibrate. This may include controlling the air valve module 120 to intermittently deflate during the suction cycle of a simulated sucking cycle. In this embodiment, the vibration of the sucking component is achieved by controlling the operation of the air valve module 120 during the suction cycle. Specifically, controlling the air valve module 120 to intermittently deflate during the suction cycle allows the air pressure within the enclosed space formed by the sucking component covering the breast to change rapidly due to the intermittent deflation of the air valve module 120 during the suction process of the air pump module 110, thereby causing the sucking component to vibrate and achieving a vibration massage effect during the sucking process.

[0027] Specifically, in the above embodiment, the control module 130 controls the air valve module 120 to intermittently deflate during the air extraction cycle in a simulated sucking cycle, which may include: outputting a first control signal to the air pump module 110 to control the air pump module 110 to extract air from the enclosed space within a first time interval; and outputting a second control signal to the air valve module 120 to control the air valve module 120 to perform at least two semi-deflation actions on the enclosed space within the first time interval. The semi-deflation action refers to the action of the air pump defusing air in the enclosed space to form a negative pressure and then performing a short-term deflation through the air valve. This deflation action is very short, so that the negative pressure value in the enclosed space is insufficient to recover to half the level before deflation. In this embodiment, intermittent deflation within the air extraction cycle is achieved by controlling the air valve module 120 to perform at least two semi-deflation actions within the air extraction cycle.

[0028] In an embodiment of the present application, for the at least two semi-deflation actions described above, the duration of each semi-deflation action may satisfy the first condition, and the time interval between two adjacent semi-deflation actions may satisfy the second condition. In this embodiment, by controlling the duration of each semi-deflation action and the time interval between two adjacent semi-deflation actions, the gas pressure within the enclosed space formed by the breast pump component covering the breast can be more accurately controlled, thereby achieving quantifiable intermittent deflation within the pumping cycle that can be customized to the user's needs, thereby controlling the vibration amplitude and frequency of the breast pump component and improving the product experience.

[0029] Specifically, the duration of each semi-deflation action can be associated with the deflation period in a simulated sucking cycle. Furthermore, the time interval between two adjacent semi-deflation actions can be associated with the duration of each semi-deflation action. For example, in one example, the duration of each semi-deflation action can be greater than zero and less than or equal to 0.3 times the deflation period; and the time interval between two adjacent semi-deflation actions can be greater than or equal to the duration of each semi-deflation action. Based on this example, the duration of each semi-deflation action meeting the first condition can mean that the duration of each semi-deflation action is greater than zero and less than or equal to 0.3 times the deflation period; and the time interval between two adjacent semi-deflation actions meeting the second condition can mean that the time interval between two adjacent semi-deflation actions is greater than or equal to the duration of each semi-deflation action. The numerical values ​​in this example are exemplary results obtained by the applicant in experiments. These results can produce a rapid step-wise change in the air pressure within the enclosed space formed by the breast cover of the breast pump during simulated sucking, thereby achieving noticeable physical vibration and achieving a vibration massage effect during breastfeeding.

[0030] Furthermore, in an embodiment of the present application, the control module 130 may control the air valve module 120 to perform an initial semi-deflation operation on the enclosed space formed by the breast pump cover after a third time interval following the start of the first time interval. In this embodiment, the control module 130 controls the air valve module 120 to perform the initial semi-deflation operation a certain time after the start of the suction cycle, thereby making the semi-deflation operation more effective.

[0031] In another embodiment of the present application, the control module 130 controls the operation of the air pump module 110 or the air valve module 120 during a simulated sucking cycle to cause the milk suction component to vibrate. This may include controlling the air pump module 110 to intermittently pump air during the pumping period of the simulated sucking cycle. In this embodiment, the vibration effect of the milk suction component is achieved by controlling the operation of the air pump module 110 during the pumping period. Specifically, the air pump module 110 is controlled to pump air intermittently rather than continuously during the pumping period. In this way, during the process of the air pump module 110 pumping air, the intermittent pumping can prevent the negative pressure of the air within the enclosed space formed by the milk suction component covering the breast from increasing continuously. Instead, the negative pressure increases and remains constant at times, thereby causing the air pressure within the enclosed space to change in a step-by-step manner, thereby causing the milk suction component to vibrate and achieving a vibration massage effect during the milk suction process.

[0032] In another embodiment of the present application, the control module 130 controls the operation of the air pump module 110 or the air valve module 120 during a simulated sucking cycle to cause the sucking component to vibrate. This may include controlling the air pump module 110 to perform uneven pumping during the pumping cycle of the simulated sucking cycle. In this embodiment, the vibration of the sucking component is achieved by controlling the operation of the air pump module 110 during the pumping cycle. Specifically, the air pump module 110 is controlled to pump unevenly rather than uniformly during the pumping cycle. As a result, during the pumping process, the air pressure within the enclosed space formed by the sucking component covering the breast does not increase uniformly and gradually, but instead increases rapidly and slowly. This causes the air pressure within the enclosed space to vary unevenly, thereby causing the sucking component to vibrate and achieving a vibration massage effect during the sucking process. Specifically, the control module 130 may periodically adjust the duty cycle of the control signal to the air pump module 110 during the pumping cycle to achieve uneven pumping.

[0033] In other embodiments of the present application, during a simulated sucking cycle, the control module 130 may further control the operation of the air pump module 110 and the air valve module 120 to cause the milk suction component to vibrate, such as by combining intermittent air release and intermittent air extraction as described in the previous embodiments. Any method that can rapidly change the negative pressure of air in the enclosed space formed by the milk suction component covering the breast and cause the milk suction component to vibrate will suffice.

[0034] In an embodiment of the present application, the aforementioned air pump module 110 may include an air pump, an air pump power supply and a first switch. When the first switch is turned on, the air pump power supply supplies power to the air pump so that the air pump performs air extraction. When the first switch is turned off, the air pump stops extracting air. The control module 130 outputs a control signal to control the opening and closing of the first switch, thereby controlling the operation of the air pump module 110. The first switch may be a MOS switch tube. Similarly, the aforementioned gas valve module 120 includes a gas valve, a gas valve power supply and a second switch. When the second switch is turned on, the gas valve power supply supplies power to the gas valve so that the gas valve performs air deflation. When the second switch is turned off, the gas valve stops air deflation. The control module 130 outputs a control signal to control the opening and closing of the second switch, thereby controlling the operation of the gas valve module 120. The second switch may be a MOS switch tube. In addition, the aforementioned control module 130 may be a microcontroller, such as a microcontroller unit (MCU). The following is in conjunction with Figure 2 and Figure 3 The structure and control logic of a drive control device for a breast pump in a specific example are described.

[0035] Figure 2FIG. 2 shows a more detailed schematic structural block diagram of a drive control device 200 for a breast pump according to an embodiment of the present application. Figure 2 As shown, the drive control device 200 for a breast pump includes an air pump power supply, an air pump and its first switch, an air valve power supply, an air valve and its second switch, and an MCU. Among them, the MCU outputs a PUMP_PWM signal and a Valve_EN signal. The PUMP_PWM signal is a pulse width modulation (PWM) signal output by the MCU, which is used to control the power switch of the air pump. When PUMP_PWM is at a high level or greater than a 50% positive duty cycle signal, the air pump performs air pumping, and when PUMP_PWM is at a low level, the air pump stops pumping. The Valve_EN signal is a general input and output (GPIO) signal or a PWM signal output by the MCU, which is used to control the power switch of the air valve. When Valve_EN is at a high level or greater than a 50% duty cycle signal, the air valve opens to deflate, and when Valve_EN is at a low level, the air valve is closed.

[0036] Figure 3 FIG. 2 is a schematic diagram showing a control signal of a drive control device 200 for a breast pump according to an embodiment of the present application. Figure 3 As shown, PUMP_PWM is the control signal of the air pump, and Valve_EN is the control signal of the air valve. Figure 3 The example shown is described as the first embodiment in the previous text (i.e. the control module controls the air valve module to intermittently deflate during the suction cycle of a simulated sucking cycle). Figure 3 As shown, T1 is the time from the start of the air pump to the first semi-deflation of the air valve; T2 is the duration of the valve semi-deflation; T3 is the interval between the two semi-deflations; T4 is the air pump pumping phase (pumping cycle), during which the negative pressure inside the bell housing gradually increases; T5 is the air valve deflation phase (deflation cycle), during which the air pressure inside the bell housing gradually recovers. Here, T1 > 0, 0 < T2 ≤ 0.3 * T5, and T3 ≥ T2. The specific values ​​of T1 to T5 are related to the performance of the air pump and valve.

[0037] exist Figure 3 In the example shown, time T4 is the pump motor's pumping phase, generating negative pressure to effectively extract breast milk. Time T5 is the valve deflation phase, restoring air pressure. Time T2 is the semi-deflation control phase during the pumping process. During T4, intermittent deflation of the valve creates a rapid change in air pressure, causing the breast cup to vibrate.

[0038] Based on the above description, the drive control device for a breast pump according to the embodiment of the present application adjusts the working state of the air pump and the air valve during a complete pumping + deflation cycle (i.e., a simulated sucking cycle) to make the air pressure generated during the pumping process uneven, thereby producing a vibration effect, thereby achieving a massage-like dredging of the entire breast during the milking process. This not only improves milking efficiency but also reduces milk discharge blockages, thereby improving the user experience. In addition, the drive control device for a breast pump according to the embodiment of the present application is technically simple to implement and does not require additional space, and can be used in both wearable and portable breast pumps.
