Description

Technical Field

[0001] This application relates to the field of breast pump milk volume detection technology, and in particular to a breast pump, detection method and storage medium. Background Technology

[0002] With societal development, people's material lives are becoming increasingly abundant, but the pace of life is also accelerating. Childbirth is an indispensable activity for human reproduction; however, in this fast-paced society, many working women find it difficult to breastfeed according to their infants' needs. Furthermore, with improved living conditions, breastfeeding women often produce a surplus of breast milk. Therefore, expressing and storing breast milk is beneficial for both immediate breastfeeding and storing excess milk to ensure effective breastfeeding for infants in situations where milk production decreases or breastfeeding is inconvenient for the mother.

[0003] As a portable and convenient breast pumping device, breast pumps are receiving increasing attention. Their functions and structures are constantly being improved so that they can perform breast pumping more safely and efficiently, and enhance the user experience.

[0004] However, during or after pumping, users usually rely on the markings on the breast pump to determine the amount of milk. This is not only inconvenient, but users often have inaccurate readings due to differences in the angle or method of observation, making it difficult for them to know the accurate amount of milk in the pump.

[0005] It is evident that how to detect the amount of milk in a breast pump is a technical problem that urgently needs to be solved. Summary of the Invention

[0120] Example 1

[0121] Please see Figure 14 In some embodiments of this application, a breast pump 10 is proposed for drawing milk from the breast and storing it in a milk storage container 14, comprising: a housing 11, a milk storage container 14, a detection unit 20, and a processing unit 30.

[0122] The detection unit 20 detects at least a portion of the detection data from the breast pump 10. The processing unit 30 is configured to determine the milk volume data within the breast pump 10 based on the detection data.

[0123] The detection unit 20 acquires at least a portion of the detection data of the breast pump 10, and then determines the milk volume data in the breast pump 10 based on the detection data.

[0124] In this way, the amount of milk in the breast pump 10 can be detected, so that the user can conveniently and accurately know the amount of milk in the breast pump 10.

[0125] The test data may include the weight of the breast pump 10 containing milk.

[0126] Understandably, the weight of the breast pump 10 remains constant and can be measured beforehand as a constant. After the detection unit 20 acquires the detection data, it can determine the weight of the breast pump 10 after it is filled with milk. Then, by subtracting the weight of the breast pump 10 itself from the weight of the breast pump 10 after it is filled with milk, the weight of the milk in the breast pump 10 can be determined. In this way, the amount of milk in the breast pump 10 can be determined.

[0127] In some embodiments of this application, the detection unit 20 is a weight detection module 50, and the milk volume data is the milk weight data.

[0128] The weight of the breast pump 10 after it is filled with milk is detected by the weight detection module 50. Then, the weight of the breast pump 10 itself is subtracted from the weight of the breast pump 10 after it is filled with milk to determine the weight of the milk in the breast pump 10. In this way, the amount of milk in the breast pump 10 is determined.

[0129] In some embodiments of this application, the weight detection module 50 includes a weight sensor 51 disposed on the breast pump 10, the weight sensor 51 detecting the weight of at least the milk storage container 14 of the breast pump 10.

[0130] The weight of the breast pump 10 or the milk storage container 14 is detected by the weight sensor 51. When the milk storage container 14 is filled with milk, the weight of the breast pump 10 or the milk storage container 14 will change. By subtracting the weight of the breast pump 10 or the milk storage container 14 when it is empty from the detected weight, the weight of the milk in the milk storage container 14 can be determined, thus determining the amount of milk in the breast pump 10.

[0131] In some embodiments of this application, a weight sensor 51 is disposed on the outer surface of the breast pump 10.

[0132] The weight sensor 51 can be set at the bottom of the breast pump 10. When the breast pump 10 is placed on the loading platform, the total weight of the breast pump 10 and the milk can be detected by the weight sensor 51. Then, the weight of the breast pump 10 itself is subtracted from the total weight of the breast pump 10 and the milk to determine the weight of the milk in the breast pump 10. In this way, the milk volume data in the breast pump 10 is determined.

[0133] In some embodiments of this application, the detection unit 20 includes a lifting component 16 disposed on the breast pump 10, and the lifting component 16 is connected to the weight detection module 50. When the lifting component 16 is lifted to suspend the breast pump 10 in the air, the weight detection module 50 is triggered; or when the lifting component 16 is lifted to suspend the breast pump 10 in the air, it enters a detectable state, and is then triggered in conjunction with other actions, such as tapping, voice, triggering buttons, etc.

[0134] The weight sensor 51 can be set on the side or top of the breast pump 10. The breast pump 10 can be suspended by lifting the lifting assembly 16, and then the weight detection module 50 can detect the total weight of the breast pump 10 and the milk. The weight of the breast pump 10 itself is then subtracted from the total weight of the breast pump 10 and the milk to determine the weight of the milk in the breast pump 10. In this way, the milk volume data in the breast pump 10 is determined.

[0135] Example 2

[0136] Please see Figures 1 to 2 In some embodiments of this application, a breast pump 10 is proposed for drawing milk from the breast and storing it in a milk storage container 14, comprising: a housing 11, a milk storage container 14, a detection unit 20, and a processing unit 30.

[0137] The milk storage container 14 is mounted on the housing 11. A detection unit 20 is located at the junction of the milk storage container 14 and the housing 11 to acquire detection data after the milk storage container 14 is filled with milk. The processing unit 30 is configured to determine the amount of milk in the milk storage container 14 based on the detection data.

[0138] The milk storage container 14 is hung on the housing 11, and the detection unit 20 is placed at the junction of the milk storage container 14 and the housing 11. During the milk pumping process, the detection unit 20 acquires detection data, and the processing unit 30 determines the milk volume data in the milk storage container 14 based on the detection data detected by the detection unit 20.

[0139] In this way, the amount of milk in the milk storage container 14 of the breast pump 10 is detected during the milk pumping process.

[0140] By monitoring the milk level in the storage container 14 during the pumping process, the user can know the milk level in the storage container 14 while using the breast pump 10, thus eliminating the need to remove the breast pump 10 for observation. This reduces the risk of milk exposure and contamination. Monitoring the milk level in the storage container 14 during pumping eliminates the need to remove the breast pump 10 for observation, thereby improving pumping efficiency. Since the breast pump 10 does not need to be removed, the vacuum within the breast pump 10 is not disrupted, allowing the breast pump 10 to maintain continuous pumping operation, further improving efficiency. By monitoring the milk level in the storage container 14, the breast pump 10 stops working or issues an alarm when the milk level in the storage container 14 reaches a threshold, thus maintaining the milk level in the storage container 14 within a safe range and preventing milk overflow.

[0141] In some embodiments of this application, the housing 11 is provided with a support portion 12, the support portion 12 is provided with a hanging interface 13, and the milk storage container 14 is provided with a hanging part 15. The milk storage container 14 is hung on the housing 11 by the support portion 12 supporting the hanging part 15.

[0142] During the pumping process of the breast pump 10, milk flows into the milk storage container 14, which holds the milk pumped by the breast pump 10. As the pumping continues, the amount of milk in the milk storage container 14 gradually increases, thus increasing the total weight of the milk storage container 14 and the milk it holds. In this situation, since the milk storage container 14 is attached to the housing 11 by the support part 12 supporting the hook part 15, the force between the hook part 15 and the support part 12 increases with the increase in the total weight of the milk storage container 14 and the milk it holds. By placing the detection unit 20 at the junction of the milk storage container 14 and the housing 11, i.e., between the support part 12 and the hook part 15, the change in the force between the hook part 15 and the support part 12 causes a change in the detection data detected by the detection unit 20. Therefore, the change in the amount of milk in the milk storage container 14 can be determined based on the change in the detection data. The milk volume data includes one or more of the following: the volume and weight of the milk in the milk storage container 14, and the percentage of the milk volume in the milk storage container 14. Thus, the milk volume data in the milk storage container 14 is determined by the detection data detected by the detection unit 20, thereby enabling the detection of the milk volume in the milk storage container 14 of the breast pump 10 during the milk expression process.

[0143] Please see Figures 1 to 3 or Figure 5 In some embodiments of this application, the hook-on portion 15 is disposed at the inlet of the milk storage container 14, and the hook-on portion 15 is flange-shaped. The inlet diameter of the milk storage container 14 is less than or equal to the diameter of the hook-on interface 13. The diameter of the hook-on portion 15 is greater than the diameter of the hook-on interface 13. The detection unit 20 is located between the support portion 12 and the hook-on portion 15, with one end of the detection unit 20 connected to the support portion 12 and the other end of the detection unit 20 connected to the hook-on portion 15.

[0144] By placing the hook part 15 at the inlet of the milk storage container 14, the distance from the center of gravity of the milk storage container 14 and the milk inside to the junction of the milk storage container 14 and the shell 11 is within the expected range, thereby improving the stability of the direction of the force between the milk storage container 14 and the shell 11, reducing the fluctuation of the detection data detected by the detection unit 20, and improving the stability and reliability of the detection data.

[0145] By configuring the inlet diameter of the milk storage container 14 to be less than or equal to the diameter of the hanging interface 13, the milk storage container 14 can be at least partially inserted into the housing 11. The side wall of the hanging interface 13 then limits the milk storage container 14, thereby reducing the shaking of the milk storage container 14, improving the stability of the direction of the force between the milk storage container 14 and the housing 11, reducing the fluctuation of the detection data detected by the detection unit 20, and improving the stability and reliability of the detection data.

[0146] By making the diameter of the hook part 15 larger than the diameter of the hook interface 13, an annular space is formed between the hook part 15 and the support part 12, allowing the detection unit 20 to be connected to both the support part 12 and the hook part 15 simultaneously. This connects the housing 11 to the milk storage container 14 via the detection unit 20. When the force between the hook part 15 and the support part 12 changes, the detection data detected by the detection unit 20 changes. Based on this change in detection data, the change in milk volume within the milk storage container 14 can be determined, thus establishing the milk volume data within the milk storage container 14. In this way, the milk volume in the milk storage container 14 of the breast pump 10 can be detected during the milk pumping process.

[0147] Please see Figures 1 to 3 In some embodiments of this application, the hook-on portion 15 may be disposed inside the housing 11. In this case, the detection unit 20 provides support for the hook-on portion 15 between the support portion 12 and the hook-on portion 15, and the force on the detection unit 20 is the pressure exerted by the hook-on portion 15 on the detection unit 20. During the milk pumping operation of the breast pump 10, the amount of milk in the milk storage container 14 gradually increases, thereby increasing the total weight of the milk storage container 14 and the milk inside it. This causes the hook-on portion 15 of the milk storage container 14 to move closer to the support portion 12 of the housing 11, or increases the tendency of the hook-on portion 15 to move closer to the support portion 12, thereby increasing the pressure exerted by the hook-on portion 15 on the detection unit 20. This causes a change in the detection data of the detection unit 20, and the change in the amount of milk in the milk storage container 14 can be determined based on the change in the detection data. The amount of milk includes one or more of the following: the volume of milk in the milk storage container 14, the weight, and the percentage of the milk volume in the milk storage container 14. Thus, the amount of milk in the milk storage container 14 is determined by the detection data detected by the detection unit 20, thereby enabling the detection of the amount of milk in the milk storage container 14 of the breast pump 10 during the milk pumping process.

[0148] Example 3

[0149] Please see Figures 1 to 2 and Figure 6In some embodiments of this application, the hook-on portion 15 may be disposed outside the housing 11. In this case, the detection unit 20 connects to the hook-on portion 15 between the support portion 12 and the hook-on portion 15, and the force on the detection unit 20 is the pulling force exerted by the hook-on portion 15 on the detection unit 20. During the milk pumping operation of the breast pump 10, the amount of milk in the milk storage container 14 gradually increases, thereby increasing the total weight of the milk storage container 14 and the milk inside it. This causes the hook-on portion 15 of the milk storage container 14 to move away from the support portion 12 of the housing 11, or increases the tendency of the hook-on portion 15 to move away from the support portion 12, thereby increasing the pulling force exerted by the hook-on portion 15 on the detection unit 20. This causes a change in the detection data of the detection unit 20, and the change in the amount of milk in the milk storage container 14 can be determined based on the change in the detection data. The amount of milk includes one or more of the following: the volume of milk in the milk storage container 14, the weight, and the percentage of the milk volume in the milk storage container 14. Thus, the milk volume data in the milk storage container 14 is determined by the detection data detected by the detection unit 20, thereby enabling the detection of the milk volume in the milk storage container 14 of the breast pump 10 during the milk pumping process. A guide structure can be provided at the inlet of the milk storage container 14 and / or the hanging interface 13 of the shell 11 to guide and position the milk storage container 14 between it and the shell 11, thereby reducing the shaking of the milk storage container 14, improving the stability of the direction of the force between the milk storage container 14 and the shell 11, reducing fluctuations in the detection data detected by the detection unit 20, and improving the stability and reliability of the detection data.

[0150] Example 4

[0151] Please see Figures 1 to 3 In some embodiments of this application, the detection unit 20 includes at least one elastic element 21 and at least one distance sensor 22. Both the elastic element 21 and the distance sensor 22 are located between the support portion 12 and the hanging portion 15. The distance sensor 22 is connected to the processing unit 30. One end of the elastic element 21 is connected to the support portion 12, and the other end is connected to the hanging portion 15. The distance sensor 22 is used to detect the distance data between the support portion 12 and the hanging portion 15. The detected data is distance data.

[0152] Please see Figures 1 to 3 In some embodiments of this application, the mounting portion 15 may be disposed inside the housing 11, one end of the elastic member 21 abuts against the bearing portion 12, and the other end of the elastic member 21 abuts against the mounting portion 15. At this time, the elastic member 21 provides support for the mounting portion 15 between the bearing portion 12 and the mounting portion 15, and the force received by the detection unit 20 is the pressure exerted by the mounting portion 15 on the elastic member 21.

[0153] During the milk pumping process, the amount of milk in the milk storage container 14 gradually increases, thereby increasing the total weight of the milk storage container 14 and the milk inside, which in turn overcomes the elastic force of the elastic member 21, causing the hanging part 15 of the milk storage container 14 to approach the supporting part 12 of the housing 11. At this time, the distance data detected by the distance sensor 22 decreases.

[0154] A database can be established by calibration, corresponding to distance data and milk volume data. Once the detection unit 20 detects the distance data, it can determine the milk volume in the milk storage container 14 by querying the database.

[0155] In this way, the amount of milk in the milk storage container 14 of the breast pump 10 is detected during the milk pumping process.

[0156] Please see Figures 3 to 4 In some embodiments of this application, the number of elastic elements 21 is at least three, and the elastic elements 21 are distributed in a circular array along the central axis of the hanging interface 13.

[0157] By having at least three elastic elements 21 arranged in a circular array along the central axis of the hanging interface 13, the elastic elements 21 are arranged in a circular array along the annular space between the bearing part 12 and the hanging part 15, ensuring the uniformity of the force on the detection unit 20, preventing the detection unit 20 from being subjected to uneven force, which would cause the detection data to deviate or become invalid, thereby improving the reliability and accuracy of the detection data detected by the detection unit 20.

[0158] In some embodiments of this application, the elastic element 21 is a compression spring. Since the elongation of a compression spring is proportional to the magnitude of the force applied, the change in the length of the elastic element 21 is proportional to the change in the amount of milk in the milk storage container 14. Therefore, the change in the amount of milk in the milk storage container 14 can be calculated based on the unit length change of the elastic element 21 when the milk storage container 14 is loaded with a unit amount of milk, using this as a calculation constant. Furthermore, the real-time amount of milk in the milk storage container 14 during the milk extraction process can be calculated based on the real-time length of the elastic element 21.

[0159] Let the length of the elastic element 21 when the milk storage container 14 is empty be L1, the length of the elastic element 21 after the milk storage container 14 is filled with a unit amount of milk be L2, the real-time length of the elastic element 21 be L3, the unit length change of the elastic element 21 be a, the unit milk volume be b, and the change in the amount of milk in the milk storage container 14 be x. Then:

[0160] a = L1 - L2;

[0161] x = [(L1-L3) / a]*b.

[0162] Since one end of the elastic member 21 abuts against the bearing part 12 and the other end of the elastic member 21 abuts against the hanging part 15, the distance between the bearing part 12 and the hanging part 15 measured by the distance sensor 22 is the length of the elastic member 21.

[0163] Therefore, the length L1 of the elastic element 21 when the milk storage container 14 is empty, the length L2 of the elastic element 21 after the milk storage container 14 is filled with a unit amount of milk, and the real-time length L3 of the elastic element 21 can be measured by the distance sensor 22. L1 and L2 are constants after calibration, and L3 is the real-time parameter measured by the distance sensor 22. The unit milk volume b is a constant set during calibration.

[0164] In this way, the change in milk volume in the milk storage container 14 can be calculated using the formula. Furthermore, the calibration process uses an empty milk storage container 14 as a reference; therefore, the change in milk volume in the milk storage container 14 represents the real-time milk volume. Thus, the milk volume in the milk storage container 14 of the breast pump 10 is monitored during the pumping process.

[0165] Example 5

[0166] Please see Figures 1 to 2 and Figure 6 In some embodiments of this application, the detection unit 20 includes at least one elastic element 21 and at least one distance sensor 22. Both the elastic element 21 and the distance sensor 22 are located between the support portion 12 and the hanging portion 15. The distance sensor 22 is connected to the processing unit 30. One end of the elastic element 21 is connected to the support portion 12, and the other end is connected to the hanging portion 15. The distance sensor 22 is used to detect the distance data between the support portion 12 and the hanging portion 15. The detected data is distance data.

[0167] Please see Figures 1 to 3 In some embodiments of this application, the mounting part 15 may be disposed outside the housing 11, one end of the elastic member 21 is connected to the bearing part 12, and the other end of the elastic member 21 is connected to the mounting part 15. At this time, the elastic member 21 connects the mounting part 15 between the bearing part 12 and the mounting part 15, and the force received by the detection unit 20 is the tension generated by the mounting part 15 on the elastic member 21.

[0168] During the milk pumping process, the amount of milk in the milk storage container 14 gradually increases, thereby increasing the total weight of the milk storage container 14 and the milk inside, which in turn overcomes the elastic force of the elastic member 21 and moves the hanging part 15 of the milk storage container 14 away from the supporting part 12 of the housing 11. At this time, the distance data detected by the distance sensor 22 increases.

[0169] A database can be established by calibration, corresponding to distance data and milk volume data. Once the detection unit 20 detects the distance data, it can determine the milk volume in the milk storage container 14 by querying the database.

[0170] In this way, the amount of milk in the milk storage container 14 of the breast pump 10 is detected during the milk pumping process.

[0171] Please see Figures 1 to 2 and Figure 6 In some embodiments of this application, the inner diameter of the elastic member 21 is larger than the diameter of the inlet of the milk storage container 14, the inner diameter of the elastic member 21 is smaller than the outer diameter of the hook part 15, and the elastic member 21 is coaxial with the hook interface 13.

[0172] By limiting the size of the elastic element 21, the elastic element 21 can be fitted onto the junction of the milk storage container 14 and the shell 11, and the central axis of the elastic element 21 is collinear with the central axis of the inlet of the milk storage container 14, thereby connecting the milk storage container 14 and the shell 11 through the annular or cylindrical elastic element 21.

[0173] In some embodiments of this application, a guide structure may be provided at the inlet of the milk storage container 14 and / or the hanging interface 13 of the shell 11, thereby guiding and restricting the position of the milk storage container 14 between the milk storage container 14 and the shell 11, thereby reducing the shaking of the milk storage container 14, improving the stability of the direction of the force between the milk storage container 14 and the shell 11, reducing the fluctuation of the detection data detected by the detection unit 20, and improving the stability and reliability of the detection data.

[0174] In some embodiments of this application, the elastic element 21 is a tension spring. Since the elongation of a tension spring is proportional to the magnitude of the force applied, the change in the length of the elastic element 21 is proportional to the change in the amount of milk in the milk storage container 14. Therefore, the change in the amount of milk in the milk storage container 14 can be calculated by using the unit length change of the elastic element 21 under a unit amount of milk loaded in the milk storage container 14 as a calculation constant, based on the change in the length of the elastic element 21. Furthermore, the real-time amount of milk in the milk storage container 14 during the milk extraction process can be calculated based on the real-time length of the elastic element 21.

[0175] Let the length of the elastic element 21 when the milk storage container 14 is empty be L1', the length of the elastic element 21 after the milk storage container 14 is filled with a unit amount of milk be L2', the real-time length of the elastic element 21 be L3', the unit length change of the elastic element 21 be a', the unit milk volume be b', and the change in the amount of milk in the milk storage container 14 be x', then:

[0176] A' = L2' - L1';

[0177] x' = [(L3'-L1') / a']*b'.

[0178] Since one end of the elastic member 21 abuts against the bearing part 12 and the other end of the elastic member 21 abuts against the hanging part 15, the distance between the bearing part 12 and the hanging part 15 measured by the distance sensor 22 is the length of the elastic member 21.

[0179] Therefore, the length L1' of the elastic element 21 when the milk storage container 14 is empty, the length L2' of the elastic element 21 after the milk storage container 14 is filled with a unit amount of milk, and the real-time length L3' of the elastic element 21 can be measured by the distance sensor 22. L1' and L2' are constants after calibration, and L3' is the real-time parameter measured by the distance sensor 22. The unit milk volume b' is a constant set during calibration.

[0180] In this way, the change in milk volume in the milk storage container 14 can be calculated using the formula. Furthermore, the calibration process uses an empty milk storage container 14 as a reference; therefore, the change in milk volume in the milk storage container 14 represents the real-time milk volume. Thus, the milk volume in the milk storage container 14 of the breast pump 10 is monitored during the pumping process.

[0181] Example 6

[0182] Please see Figures 1 to 4 In some embodiments of this application, the number of distance sensors 22 and the number of elastic elements 21 are both at least three, and the distance sensors 22 and elastic elements 21 are distributed in a circular array along the central axis of the hanging interface 13.

[0183] By having at least three elastic elements 21 arranged in a circular array along the central axis of the hanging interface 13, the elastic elements 21 are arranged in a circular array along the annular space between the bearing part 12 and the hanging part 15, ensuring the uniformity of the force on the detection unit 20, preventing the detection unit 20 from being subjected to uneven force, which would cause the detection data to deviate or become invalid, thereby improving the reliability and accuracy of the detection data detected by the detection unit 20.

[0184] The distance between the bearing part 12 and the hanging part 15 is detected by at least three distance sensors 22. Then, by calculating the median, calculating the average, fitting a virtual plane by least squares method and other data processing algorithms, the distance between the bearing part 12 and the hanging part 15, i.e. the fitting length of the elastic element 21, is calculated based on the distance data detected by all distance sensors 22. This reduces the error caused by uneven force on the elastic element 21, thereby improving the reliability and accuracy of the detection data acquired by the detection unit 20.

[0185] In some embodiments of this application, at least three of the distance sensors 22 are positioned one-to-one with the positions of the elastic element 21. The distance sensors 22, which are positioned one-to-one with the elastic element 21, are arranged in a circular array along the central axis of the mounting interface 13.

[0186] By ensuring a one-to-one correspondence between the position of the distance sensor 22 and the position of the elastic element 21, the distance sensor 22 can more accurately detect changes in the length of the corresponding elastic element 21, thereby improving the reliability of the distance data detected by the distance sensor 22. By detecting the distance between the bearing part 12 and the hanging part 15 using at least three distance sensors 22, and then using median calculation, average calculation, least squares fitting of a virtual plane, and other data processing algorithms, the distance between the bearing part 12 and the hanging part 15, i.e., the fitted length of the elastic element 21, is calculated based on the distance data detected by all distance sensors 22. This reduces errors caused by uneven force on the elastic element 21, thereby improving the reliability and accuracy of the detection data acquired by the detection unit 20.

[0187] In some embodiments of this application, the processing unit 30 is configured to determine the tilt state of the milk storage container 14 based on the relationship between distance data detected by the distance sensor 22.

[0188] During the pumping process of the breast pump 10, factors such as the user's posture can cause the breast pump 10 to tilt during operation, which in turn causes the milk storage container 14 to tilt. This results in an angle between the liquid level in the milk storage container 14 and the cross-section of the milk storage container 14, leading to inaccurate and excessively deviated milk volume data. Furthermore, if the tilt angle of the milk storage container 14 is too large, milk may overflow from the milk storage container 14.

[0189] Since the gravity acting on the milk storage container 14 and the milk inside it is always vertically downward, when the milk storage container 14 is tilted, the direction of the gravity acting on the milk storage container 14 and the milk inside it will be at an angle to the normal of the hooking surface of the hooking part 15 of the milk storage container 14. This angle is the tilt angle of the milk storage container 14.

[0190] The milk storage container 14 is connected to the housing 11 via an elastic element 21. Therefore, when the breast pump 10 tilts, the tilting trends of the housing 11 and the milk storage container 14 are different. The housing 11 tilts synchronously with the breast pump 10, while the tilting of the milk storage container 14 lags behind that of the housing 11. Furthermore, due to the elastic deformation of the elastic element 21, the tilt angle of the milk storage container 14 is smaller than that of the housing 11. Therefore, when the milk storage container 14 tilts, the force on the elastic element 21 at different locations varies, leading to differences in the deformation of the elastic element 21 at different locations, and consequently, differences in the distance data detected by the distance sensor 22 at different locations.

[0191] When the breast pump 10 tilts, causing the milk storage container 14 to tilt, the elastic element 21 near the inner side of the tilt direction of the milk storage container 14 tends to be compressed more, while the elastic element 21 near the outer side of the tilt direction of the milk storage container 14 tends to be stretched more. Therefore, in this situation, the length of the elastic element 21 near the inner side of the tilt direction of the milk storage container 14 decreases, and the length of the elastic element 21 near the outer side of the tilt direction of the milk storage container 14 increases. At this time, the distance data detected by the distance sensor 22 near the inner side of the tilt direction of the milk storage container 14 decreases, and the distance data detected by the distance sensor 22 near the outer side of the tilt direction of the milk storage container 14 increases. Thus, the tilt state of the milk storage container 14 can be determined based on the above pattern. Furthermore, the degree of tilt of the milk storage container 14 can be judged based on the difference in distance data detected by the distance sensors 22 near the inner and outer sides of the tilt direction of the milk storage container 14.

[0192] Distance data detected by the distance sensor 22 at different angles under different milk volumes in the milk storage container 14 can be obtained by calibrating each data point individually, and a database can be formed.

[0193] During the milk pumping process, the real-time tilt angle of the milk storage container 14 can be determined by comparing the real-time data detected by the distance sensor 22 with the relevant data in the database.

[0194] In some embodiments of this application, when the milk storage container 14 is not tilted, the distance data detected by the distance sensor 22 at each milk volume level during the process of the milk storage container 14 from empty to full can be acquired. When the tilt angle of the milk storage container 14 is at a tilt threshold, the distance data detected by the distance sensor 22 at each milk volume level during the process of the milk storage container 14 from empty to full can be acquired. The difference between the angle when the milk storage container 14 is not tilted and the angle at the tilt threshold is divided into several equal parts. The distance data detected by the distance sensor 22 at each milk volume level during the process of the milk storage container 14 from empty to full is calibrated at each tilt angle, and the detected distance data is associated with the tilt angle data. In this way, the calibration of the distance data and tilt angle data of the milk storage container 14 in the tilted state is completed, and a database is formed.

[0195] During the milk pumping process, the actual detected distance data can be matched with the distance data in the database by means of data fitting or taking similar values, and the tilt angle of the current milk storage container 14 can be obtained based on the distance data.

[0196] Once the milk volume data and / or tilt angle data are determined, they can be displayed on the monitor of the breast pump 10, or sent to remote devices such as mobile phones, watches, and computers via the communication unit, so that users can observe the determined relevant data information.

[0197] Thus, the tilt state of the milk storage container 14 is determined based on the relationship between the distance data detected by the distance sensor 22.

[0198] In some embodiments of this application, the processing unit 30 is configured to determine the validity of the distance data based on the tilt state information and / or to determine whether to trigger the alarm unit 40. If it is determined that the alarm unit 40 should be triggered, an alarm command is sent to the alarm unit 40.

[0199] When the tilt angle of the milk storage container 14 is too large, the differences between the distance data detected by the various distance sensors 22 are significant, and the angle between the liquid level of the milk in the milk storage container 14 and the cross-section of the milk storage container 14 is also large. This leads to a large difference between the milk volume data determined based on the distance data and the actual milk volume in the milk storage container 14. Therefore, during the milk pumping operation, if the determined tilt angle exceeds the tilt threshold, the distance data detected by the distance sensors 22 is deemed invalid.

[0200] If the determined tilt angle exceeds the tilt threshold, the risk of milk overflowing from the milk storage container 14 increases. In this case, the processing unit 30 sends an alarm command to the alarm unit 40, triggering the alarm unit 40 to issue an alarm. The alarm issued by the alarm unit 40 can be an audible and visual alarm, or the alarm information can be displayed on the breast pump 10's screen, or it can be sent to a remote device such as a mobile phone, watch, or computer via the communication unit to alert the user remotely. After receiving the alarm information, the user can adjust their posture or the angle of the breast pump 10 to keep the tilt angle of the milk storage container 14 within the tilt angle threshold, thereby reducing the risk of milk overflowing from the milk storage container 14 and ensuring that the determined milk volume data meets the expected requirements.

[0201] Example 7

[0202] Please see Figures 1 to 2 and Figures 7 to 9 In some embodiments of this application, the detection unit 20 includes at least one elastic element 21 and at least one capacitive sensor 23. Both the elastic element 21 and the capacitive sensor 23 are located between the support portion 12 and the mounting portion 15. The capacitive sensor 23 is connected to the processing unit 30. One end of the elastic element 21 is connected to the support portion 12, and the other end is connected to the mounting portion 15. Changes in the distance between the mounting portion 15 and the support portion 12 cause changes in the capacitance data of the capacitive sensor 23. The detected data is capacitance data.

[0203] Please see Figures 7 to 9In some embodiments of this application, the mounting portion 15 may be disposed inside the housing 11, one end of the elastic member 21 abuts against the bearing portion 12, and the other end of the elastic member 21 abuts against the mounting portion 15. At this time, the elastic member 21 provides support for the mounting portion 15 between the bearing portion 12 and the mounting portion 15, and the force received by the detection unit 20 is the pressure exerted by the mounting portion 15 on the elastic member 21.

[0204] During the milk pumping process, the amount of milk in the milk storage container 14 gradually increases, thereby increasing the total weight of the milk storage container 14 and the milk inside. This increases the weight of the milk storage container 14 and the milk inside, thus overcoming the elastic force of the elastic member 21 and causing the hanging part 15 of the milk storage container 14 to approach the supporting part 12 of the housing 11. At this time, the capacitance data of the capacitance sensor 23 changes due to the change in the distance between the hanging part 15 and the supporting part 12.

[0205] A database corresponding to capacitance data and milk volume data can be established through calibration. When the detection unit 20 detects the capacitance data, it can determine the milk volume in the milk storage container 14 by querying the database.

[0206] In this way, the amount of milk in the milk storage container 14 of the breast pump 10 is detected during the milk pumping process.

[0207] In some embodiments of this application, the number of capacitive sensors 23 and the number of elastic elements 21 are both at least three, and the capacitive sensors 23 and elastic elements 21 are arranged in a circular array along the central axis of the hanging interface 13.

[0208] By having at least three elastic elements 21 arranged in a circular array along the central axis of the hanging interface 13, the elastic elements 21 are arranged in a circular array along the annular space between the bearing part 12 and the hanging part 15, ensuring the uniformity of the force on the detection unit 20, preventing the detection unit 20 from being subjected to uneven force, which would cause the detection data to deviate or become invalid, thereby improving the reliability and accuracy of the detection data detected by the detection unit 20.

[0209] At least three capacitive sensors 23 detect the capacitance data of the capacitive sensors 23 when the distance between the support part 12 and the hanging part 15 changes. Then, by calculating the median, calculating the average, fitting the data using the least squares method, and other data processing algorithms, the fitted capacitance data is calculated based on the capacitance data detected by all the capacitive sensors 23. The milk volume data in the milk storage container 14 is then determined based on the fitted capacitance data, reducing the error caused by uneven force on the elastic element 21, thereby improving the reliability and accuracy of the determined milk volume data in the milk storage container 14.

[0210] In some embodiments of this application, at least three of the capacitive sensors 23 are positioned one-to-one with the positions of the elastic element 21. The capacitive sensors 23, which are positioned one-to-one with the elastic element 21, are arranged in a circular array along the central axis of the mounting interface 13.

[0211] By ensuring a one-to-one correspondence between the position of the capacitive sensor 23 and the position of the elastic element 21, the capacitive sensor 23 can more accurately match the length changes of the corresponding elastic element 21, thereby improving the reliability of the capacitance data detected by the capacitive sensor 23. By acquiring capacitance data detected by at least three capacitive sensors 23, and then using median calculation, average calculation, least squares fitting of virtual values, and other data processing algorithms, fitted capacitance data is calculated based on the capacitance data detected by all capacitive sensors 23. The milk volume data within the milk storage container 14 is then determined based on the fitted capacitance data, reducing errors caused by uneven force on the elastic element 21, thereby improving the reliability and accuracy of the determined milk volume data within the milk storage container 14.

[0212] In some embodiments of this application, the processing unit 30 is configured to determine the tilt state of the milk storage container 14 based on the relationship between the capacitance data detected by the capacitance sensor 23.

[0213] During the pumping process of the breast pump 10, factors such as the user's posture can cause the breast pump 10 to tilt during operation, which in turn causes the milk storage container 14 to tilt. This results in an angle between the liquid level in the milk storage container 14 and the cross-section of the milk storage container 14, leading to inaccurate and excessively deviated milk volume data. Furthermore, if the tilt angle of the milk storage container 14 is too large, milk may overflow from the milk storage container 14.

[0214] Since the gravity acting on the milk storage container 14 and the milk inside it is always vertically downward, when the milk storage container 14 is tilted, the direction of the gravity acting on the milk storage container 14 and the milk inside it will be at an angle to the normal of the hooking surface of the hooking part 15 of the milk storage container 14. This angle is the tilt angle of the milk storage container 14.

[0215] The milk storage container 14 is connected to the housing 11 via an elastic element 21. Therefore, when the breast pump 10 tilts, the tilting trends of the housing 11 and the milk storage container 14 are different. The housing 11 tilts synchronously with the breast pump 10, while the tilting of the milk storage container 14 lags behind that of the housing 11. Furthermore, due to the elastic deformation of the elastic element 21, the tilt angle of the milk storage container 14 is smaller than that of the housing 11. Therefore, when the milk storage container 14 tilts, the force on the elastic element 21 at different locations varies, leading to differences in the deformation of the elastic element 21 at different locations, and consequently, differences in the distance data detected by the distance sensor 22 at different locations.

[0216] When the breast pump 10 tilts, causing the milk storage container 14 to tilt, the elastic element 21 near the inner side of the tilt direction of the milk storage container 14 tends to be compressed more, while the elastic element 21 near the outer side of the tilt direction of the milk storage container 14 tends to be stretched more. Therefore, in this situation, the length of the elastic element 21 near the inner side of the tilt direction of the milk storage container 14 decreases, and the length of the elastic element 21 near the outer side of the tilt direction of the milk storage container 14 increases. At this time, the distance between the support portion 12 and the hook portion 15 near the inner side of the tilt direction of the milk storage container 14 decreases, and the distance between the support portion 12 and the hook portion 15 near the outer side of the tilt direction of the milk storage container 14 increases. This results in the capacitance data change trend of the capacitance sensor 23 near the inner side of the tilt direction of the milk storage container 14 being opposite to the capacitance data change trend of the capacitance sensor 23 near the outer side of the tilt direction of the milk storage container 14. Based on the above-mentioned pattern, the difference in capacitance data detected by the capacitance sensor 23 at each position is determined, and the tilt state of the milk storage container 14 is determined based on the difference in capacitance data. The degree of tilt of the milk storage container 14 is determined based on the difference in capacitance data detected by the capacitance sensors 23 at each location.

[0217] The capacitance data of the time-capacitance sensor 23 at different angles under different milk volumes in the milk storage container 14 can be obtained by calibrating each data point individually, and a database can be formed.

[0218] During the milk pumping process, the real-time tilt angle of the milk storage container 14 can be determined by comparing the real-time data detected by the capacitive sensor 23 with the relevant data in the database.

[0219] In some embodiments of this application, when the milk storage container 14 is not tilted, the capacitance data detected by the capacitance sensor 23 can be acquired at each milk volume level during the process of the milk storage container 14 going from empty to full. When the tilt angle of the milk storage container 14 is at a tilt threshold, the capacitance data detected by the capacitance sensor 23 at each milk volume level during the process of the milk storage container 14 going from empty to full is acquired. The difference between the angle when the milk storage container 14 is not tilted and the angle at the tilt threshold is divided into several equal parts. The capacitance data detected by the capacitance sensor 23 at each tilt angle during the process of the milk storage container 14 going from empty to full is calibrated, and the detected capacitance data is associated with the tilt angle data. In this way, the calibration of the capacitance data and tilt angle data of the milk storage container 14 in the tilted state is completed, and a database is formed.

[0220] During the milk pumping process of the breast pump 10, the actual detected capacitance data can be matched with the capacitance data in the database by means of data fitting or taking similar values, and the tilt angle of the current milk storage container 14 can be obtained based on the capacitance data.

[0221] Once the milk volume data and / or tilt angle data are determined, they can be displayed on the monitor of the breast pump 10, or sent to remote devices such as mobile phones, watches, and computers via the communication unit, so that users can observe the determined relevant data information.

[0222] Thus, the tilt state of the milk storage container 14 is determined based on the relationship between the capacitance data detected by the capacitance sensor 23.

[0223] Please see Figures 1 to 2 In some embodiments of this application, the processing unit 30 is configured to determine the validity of the capacitance data based on the tilt state information and / or to determine whether to trigger the alarm unit 40. If it is determined that the alarm unit 40 should be triggered, an alarm command is sent to the alarm unit 40.

[0224] When the tilt angle of the milk storage container 14 is too large, the differences between the capacitance data detected by each capacitance sensor 23 are significant, and the angle between the liquid level of the milk in the milk storage container 14 and the cross-section of the milk storage container 14 is also large. This leads to a large difference between the milk volume data determined based on the capacitance data and the actual milk volume in the milk storage container 14. Therefore, during the milk pumping operation, if the determined tilt angle exceeds the tilt threshold, the capacitance data detected by the capacitance sensor 23 is deemed invalid.

[0225] If the determined tilt angle exceeds the tilt threshold, the risk of milk overflowing from the milk storage container 14 increases. In this case, the processing unit 30 sends an alarm command to the alarm unit 40, triggering the alarm unit 40 to issue an alarm. The alarm issued by the alarm unit 40 can be an audible and visual alarm, or the alarm information can be displayed on the breast pump 10's screen, or it can be sent to a remote device such as a mobile phone, watch, or computer via the communication unit to alert the user remotely. After receiving the alarm information, the user can adjust their posture or the angle of the breast pump 10 to keep the tilt angle of the milk storage container 14 within the tilt angle threshold, thereby reducing the risk of milk overflowing from the milk storage container 14 and ensuring that the determined milk volume data meets the expected requirements.

[0226] Example 8

[0227] Please see Figures 1 to 2 and Figure 7 In some embodiments of this application, the capacitive sensor 23 includes a first electrode 231 and a second electrode 232. The first electrode 231 is directly or indirectly fixedly mounted to the support portion 12 via a connecting structure. The second electrode 232 is directly or indirectly fixedly mounted to the mounting portion 15 via a connecting structure.

[0228] During the milk pumping process of the breast pump 10, when the amount of milk in the milk storage container 14 changes, the distance between the support part 12 and the hook part 15 will change, which in turn will cause the position between the first electrode 231 and the second electrode 232 to change, which in turn will cause the capacitance data of the capacitance sensor 23 to change, so that the amount of milk in the milk storage container 14 can be determined based on the capacitance data detected by the capacitance sensor 23.

[0229] In some embodiments of this application, the first electrode 231 is parallel to the moving direction of the support portion 12, and the second electrode 232 is parallel to the moving direction of the hook portion 15.

[0230] When the distance between the support part 12 and the hanging part 15 changes, the distance between the first electrode 231 and the second electrode 232 changes, which in turn causes the capacitance data detected by the capacitance sensor 23 to change, thereby determining the amount of milk in the milk storage container 14 based on the capacitance data.

[0231] In some embodiments of this application, the mounting portion 15 may be disposed inside the housing 11, one end of the elastic member 21 abuts against the bearing portion 12, and the other end of the elastic member 21 abuts against the mounting portion 15. At this time, the elastic member 21 provides support for the mounting portion 15 between the bearing portion 12 and the mounting portion 15, and the force received by the detection unit 20 is the pressure exerted by the mounting portion 15 on the elastic member 21.

[0232] According to the capacitance calculation formula C = eS / D, the capacitance C is directly proportional to the permittivity e of the dielectric, directly proportional to the effective area S of the electrode, and inversely proportional to the electrode distance D. Therefore, when the distance between the first electrode 231 and the second electrode 232 decreases, the capacitance data detected by the capacitance sensor 23 increases.

[0233] In some embodiments of this application, during the milk pumping process of the breast pump 10, the amount of milk in the milk storage container 14 gradually increases, thereby increasing the total weight of the milk storage container 14 and the milk inside, which in turn overcomes the elastic force of the elastic member 21, causing the hook part 15 of the milk storage container 14 to approach the support part 12 of the housing 11, thereby reducing the distance between the first electrode member 231 and the second electrode member 232. At this time, the capacitance data detected by the capacitance sensor 23 increases.

[0234] Since the change in distance between the first electrode 231 and the second electrode 232 will cause a change in the capacitance of the electrical sensor, the change in capacitance can be converted into an electrical signal output through the measurement circuit. By measuring the magnitude of the electrical signal, the magnitude of the capacitance data can be determined, that is, the capacitance data can be obtained.

[0235] A database corresponding to capacitance data and milk volume data can be established through calibration. When the detection unit 20 detects the capacitance data, it can determine the milk volume in the milk storage container 14 by querying the database.

[0236] In this way, the amount of milk in the milk storage container 14 of the breast pump 10 is detected during the milk pumping process.

[0237] In some embodiments of this application, the capacitance data when the milk storage container 14 is empty can be C1, the capacitance data after the milk storage container 14 is filled with a unit amount of milk can be C2, the real-time capacitance data can be C3, the unit capacitance data can be a, the unit milk volume can be b, and the change in the milk volume in the milk storage container 14 can be x. Then:

[0238] a = C1 - C2;

[0239] x = [(C1-C3) / a]*b.

[0240] The capacitance data C1 when the milk storage container 14 is empty, the capacitance data C2 after the milk storage container 14 is filled with a unit amount of milk, and the real-time capacitance data C3 can be obtained by converting the change in capacitance of the capacitance sensor 23 into an electrical signal output through the measuring circuit, and then calculating the capacitance by detecting the magnitude of the electrical signal. C1 and C2 are constants after calibration, and C3 is the real-time parameter of the capacitance sensor 23 measured. The unit milk volume b is a constant set during calibration.

[0241] In this way, the change in milk volume in the milk storage container 14 can be calculated using the formula. Furthermore, the calibration process uses an empty milk storage container 14 as a reference; therefore, the change in milk volume in the milk storage container 14 represents the real-time milk volume. Thus, the milk volume in the milk storage container 14 of the breast pump 10 is monitored during the pumping process.

[0242] Example 9

[0243] Please see Figures 1 to 2 and Figure 8 In some embodiments of this application, the first electrode 231 is perpendicular to the moving direction of the support portion 12, and the second electrode 232 is perpendicular to the moving direction of the hook portion 15.

[0244] When the distance between the support part 12 and the hanging part 15 changes, the area of ​​the overlapping region between the first electrode 231 and the second electrode 232 changes, thereby changing the effective area of ​​the electrodes between the first electrode 231 and the second electrode 232, which in turn changes the capacitance data detected by the capacitance sensor 23, and thus the amount of milk in the milk storage container 14 is determined based on the capacitance data.

[0245] In some embodiments of this application, the mounting portion 15 may be disposed inside the housing 11, one end of the elastic member 21 abuts against the bearing portion 12, and the other end of the elastic member 21 abuts against the mounting portion 15. At this time, the elastic member 21 provides support for the mounting portion 15 between the bearing portion 12 and the mounting portion 15, and the force received by the detection unit 20 is the pressure exerted by the mounting portion 15 on the elastic member 21.

[0246] According to the capacitance calculation formula C = eS / D, the capacitance C is directly proportional to the permittivity e of the dielectric, directly proportional to the effective electrode area S, and inversely proportional to the electrode distance D. Therefore, when the effective electrode area between the first electrode 231 and the second electrode 232 increases, the capacitance data detected by the capacitance sensor 23 increases.

[0247] In some embodiments of this application, during the milk pumping process of the breast pump 10, the amount of milk in the milk storage container 14 gradually increases, thereby increasing the total weight of the milk storage container 14 and the milk inside, which in turn overcomes the elastic force of the elastic member 21, causing the hanging part 15 of the milk storage container 14 to approach the supporting part 12 of the housing 11, thereby increasing the effective area of ​​the electrodes between the first electrode member 231 and the second electrode member 232. At this time, the capacitance data detected by the capacitance sensor 23 increases.

[0248] Since the change in distance between the first electrode 231 and the second electrode 232 will cause a change in the capacitance of the electrical sensor, the change in capacitance can be converted into an electrical signal output through the measurement circuit. By measuring the magnitude of the electrical signal, the magnitude of the capacitance data can be determined, that is, the capacitance data can be obtained.

[0249] A database corresponding to capacitance data and milk volume data can be established through calibration. When the detection unit 20 detects the capacitance data, it can determine the milk volume in the milk storage container 14 by querying the database.

[0250] In this way, the amount of milk in the milk storage container 14 of the breast pump 10 is detected during the milk pumping process.

[0251] In some embodiments of this application, the capacitance data when the milk storage container 14 is empty can be C1', the capacitance data after the milk storage container 14 is filled with a unit amount of milk can be C2', the real-time capacitance data can be C3', the unit capacitance data can be a', the unit milk volume can be b', and the change in the milk volume in the milk storage container 14 can be x'. Then:

[0252] a' = C2' - C1';

[0253] x' = [(C3'-C1') / a']*b'.

[0254] The capacitance data C1' when the milk storage container 14 is empty, C2' when the milk storage container 14 is filled with a unit amount of milk, and C3' in real time can be obtained by converting the change in capacitance of the capacitance sensor 23 into an electrical signal output through the measuring circuit, and then calculating the capacitance by detecting the magnitude of the electrical signal. C1' and C2' are constants after calibration, and C3' is the measured real-time parameter of the capacitance sensor 23. The unit milk volume b' is a constant set during calibration.

[0255] In this way, the change in milk volume in the milk storage container 14 can be calculated using the formula. Furthermore, the calibration process uses an empty milk storage container 14 as a reference; therefore, the change in milk volume in the milk storage container 14 represents the real-time milk volume. Thus, the milk volume in the milk storage container 14 of the breast pump 10 is monitored during the pumping process.

[0256] Example 10

[0257] Please see Figures 1 to 2 and Figure 9In some embodiments of this application, the capacitive sensor 23 includes a capacitor 233 and a dielectric element 234, with the dielectric element 234 inserted into the capacitor 233. One of the capacitor 233 and the dielectric element 234 is directly or indirectly fixedly mounted to one of the support portion 12 and the mounting portion 15 via a connecting structure. The other of the capacitor 233 and the dielectric element 234 is directly or indirectly fixedly mounted to the other of the support portion 12 and the mounting portion 15 via a connecting structure.

[0258] When the distance between the support part 12 and the hanging part 15 changes, the insertion amount of the dielectric element 234 in the capacitor element 233 changes, which in turn changes the capacitance of the dielectric element 234 in the capacitor element 233, and consequently changes the capacitance data detected by the capacitance sensor 23, thereby determining the amount of milk in the milk storage container 14 based on the capacitance data.

[0259] In some embodiments of this application, the mounting portion 15 may be disposed inside the housing 11, one end of the elastic member 21 abuts against the bearing portion 12, and the other end of the elastic member 21 abuts against the mounting portion 15. At this time, the elastic member 21 provides support for the mounting portion 15 between the bearing portion 12 and the mounting portion 15, and the force received by the detection unit 20 is the pressure exerted by the mounting portion 15 on the elastic member 21.

[0260] According to the capacitance calculation formula C = eS / D, the capacitance C is directly proportional to the permittivity e of the dielectric, directly proportional to the effective area S of the electrode, and inversely proportional to the electrode distance D. Therefore, when the permittivity of the dielectric element 234 in the capacitor 233 increases, the capacitance data detected by the capacitance sensor 23 increases.

[0261] In some embodiments of this application, during the milk pumping process of the breast pump 10, the amount of milk in the milk storage container 14 gradually increases, thereby increasing the total weight of the milk storage container 14 and the milk inside, which in turn overcomes the elastic force of the elastic member 21, causing the hook portion 15 of the milk storage container 14 to approach the support portion 12 of the housing 11, thereby increasing the insertion depth of the dielectric member 234 in the capacitor member 233, and thus increasing the capacitance of the dielectric member 234 in the capacitor member 233. At this time, the capacitance data detected by the capacitance sensor 23 increases.

[0262] The change in the capacitance of the dielectric element 234 in the capacitor element 233 caused by the change in the insertion amount of the dielectric element 234 in the capacitor element 233 will lead to a change in the capacitance of the electrical sensor. Through the measurement circuit, the change in capacitance can be converted into an electrical signal output. By measuring the magnitude of the electrical signal, the magnitude of the capacitance data can be determined, that is, the capacitance data can be obtained.

[0263] A database corresponding to capacitance data and milk volume data can be established through calibration. When the detection unit 20 detects the capacitance data, it can determine the milk volume in the milk storage container 14 by querying the database.

[0264] In this way, the amount of milk in the milk storage container 14 of the breast pump 10 is detected during the milk pumping process.

[0265] In some embodiments of this application, the capacitance data when the milk storage container 14 is empty can be denoted as C1", the capacitance data after the milk storage container 14 is loaded with a unit amount of milk can be denoted as C2", the real-time capacitance data can be denoted as C3", the unit capacitance data can be denoted as a", the unit milk amount can be denoted as b", and the change in the amount of milk in the milk storage container 14 can be denoted as x".

[0266] a” = C2” - C1”;

[0267] x”=[(C3”-C1”) / a”]*b”.

[0268] The capacitance data C1” when the milk storage container 14 is empty, the capacitance data C2” after the milk storage container 14 is filled with a unit amount of milk, and the real-time capacitance data C3” can be obtained by converting the change in capacitance of the capacitance sensor 23 into an electrical signal output through the measuring circuit, and then calculating the capacitance by detecting the magnitude of the electrical signal. C1” and C2” are constants after calibration, and C3” is the real-time parameter of the capacitance sensor 23 measured. The unit milk volume b” is a constant set during calibration.

[0269] In this way, the change in milk volume in the milk storage container 14 can be calculated using the formula. Furthermore, the calibration process uses an empty milk storage container 14 as a reference; therefore, the change in milk volume in the milk storage container 14 represents the real-time milk volume. Thus, the milk volume in the milk storage container 14 of the breast pump 10 is monitored during the pumping process.

[0270] Example 11

[0271] Please see Figures 1 to 2 and Figure 10 In some embodiments of this application, the detection unit 20 includes at least one pressure sensor 24, which is connected to the processing unit 30. The pressure sensor 24 is used to detect pressure data between the mounting part 15 and the supporting part 12. The measured data is pressure data.

[0272] Please see Figures 1 to 3In some embodiments of this application, the mounting part 15 may be disposed inside the housing 11, one end of the pressure sensor 24 abuts against the support part 12, and the other end of the pressure sensor 24 abuts against the mounting part 15. At this time, the pressure sensor 24 provides support for the mounting part 15 between the support part 12 and the mounting part 15, and the force received by the detection unit 20 is the pressure generated by the mounting part 15 on the pressure sensor 24.

[0273] During the milk pumping process, the amount of milk in the milk storage container 14 gradually increases, thereby increasing the total weight of the milk storage container 14 and the milk inside, which in turn increases the pressure of the hook part 15 on the pressure sensor 24. At this time, the pressure data detected by the pressure sensor 24 increases.

[0274] A database can be established by calibration, corresponding to pressure data and milk volume data. Once the detection unit 20 detects the distance data, it can determine the milk volume in the milk storage container 14 by querying the database.

[0275] In this way, the amount of milk in the milk storage container 14 of the breast pump 10 is detected during the milk pumping process.

[0276] In some embodiments of this application, the unit pressure data detected by the pressure sensor 24 under a unit volume of milk loaded in the milk storage container 14 can be used as a calculation constant, and the change in milk volume in the milk storage container 14 can be calculated based on the change in pressure data. Furthermore, the real-time milk volume in the milk storage container 14 during the milk extraction process can be calculated based on the real-time pressure data detected by the pressure data.

[0277] Let F1 be the pressure data when the milk storage container 14 is empty, F2 be the pressure data after the milk storage container 14 is filled with a unit amount of milk, F3 be the real-time pressure data, a be the unit pressure data, b be the unit milk volume, and x be the change in the milk volume in the milk storage container 14. Then:

[0278] a = F2 - F1;

[0279] x = [(F3-F1) / a]*b.

[0280] The pressure data F1 when the milk storage container 14 is empty, F2 when the milk storage container 14 is filled with a unit amount of milk, and F3, which can be measured by the distance sensor 22, are as follows: F1 and F2 are constants after calibration, and F3 is the real-time parameter measured by the distance sensor 22. The unit milk volume b is a constant set during calibration.

[0281] In this way, the change in milk volume in the milk storage container 14 can be calculated using the formula. Furthermore, the calibration process uses an empty milk storage container 14 as a reference; therefore, the change in milk volume in the milk storage container 14 represents the real-time milk volume. Thus, the milk volume in the milk storage container 14 of the breast pump 10 is monitored during the pumping process.

[0282] In some embodiments of this application, the number of pressure sensors 24 is at least three, and the pressure sensors 24 are arranged in a circular array along the central axis of the mounting interface 13.

[0283] The pressure between the bearing part 12 and the hanging part 15 is detected by at least three pressure sensors 24. Then, by calculating the median, calculating the average, fitting virtual data by the least squares method, and other data processing algorithms, the error caused by the different forces between the pressure sensors 24 is reduced based on the pressure data detected by all pressure sensors 24, thereby improving the reliability and accuracy of the detection data obtained by the detection unit 20.

[0284] In some embodiments of this application, the processing unit 30 is configured to determine the tilt state of the milk storage container 14 based on the relationship between the pressure data detected by the pressure sensor 24.

[0285] During the pumping process of the breast pump 10, factors such as the user's posture can cause the breast pump 10 to tilt during operation, which in turn causes the milk storage container 14 to tilt. This results in an angle between the liquid level in the milk storage container 14 and the cross-section of the milk storage container 14, leading to inaccurate and excessively deviated milk volume data. Furthermore, if the tilt angle of the milk storage container 14 is too large, milk may overflow from the milk storage container 14.

[0286] Since the gravity acting on the milk storage container 14 and the milk inside it is always vertically downward, when the milk storage container 14 is tilted, the direction of the gravity acting on the milk storage container 14 and the milk inside it will be at an angle to the normal of the hooking surface of the hooking part 15 of the milk storage container 14. This angle is the tilt angle of the milk storage container 14.

[0287] The milk storage container 14 is connected to the housing 11 via pressure sensor 24. Therefore, when the breast pump 10 tilts, the tilting trends of the housing 11 and the milk storage container 14 are different. The housing 11 tilts synchronously with the breast pump 10, while the tilting of the milk storage container 14 lags behind that of the housing 11, and the change in the tilt angle of the milk storage container 14 is less pronounced than that of the housing 11. Consequently, when the milk storage container 14 tilts, the force on the pressure sensor 24 at different locations will vary, resulting in differences in the pressure data detected by the pressure sensor 24 at different locations.

[0288] When the breast pump 10 tilts, causing the milk storage container 14 to tilt as well, the pressure sensor 24 located closer to the inside of the tilt direction experiences greater pressure, while the pressure sensor 24 located closer to the outside of the tilt direction experiences less pressure. At this time, the pressure data detected by the pressure sensor 24 closer to the inside of the tilt direction increases, while the pressure data detected by the pressure sensor 24 closer to the outside of the tilt direction decreases. Therefore, the tilt state of the milk storage container 14 can be determined based on this pattern. Furthermore, the degree of tilt of the milk storage container 14 can be judged based on the difference in pressure data detected by the pressure sensors 24 closer to the inside and outside of the tilt direction.

[0289] Pressure data detected by the pressure sensor 24 at different angles under different milk volumes in the milk storage container 14 can be obtained by calibrating each data point individually, and a database can be formed.

[0290] During the milk pumping process, the real-time tilt angle of the milk storage container 14 can be determined by comparing the real-time data detected by the pressure sensor 24 with the relevant data in the database.

[0291] In some embodiments of this application, when the milk storage container 14 is not tilted, pressure data detected by the pressure sensor 24 can be acquired at various milk volume levels during the process of the milk storage container 14 going from empty to full. When the tilt angle of the milk storage container 14 is at a tilt threshold, pressure data detected by the pressure sensor 24 at various milk volume levels during the process of the milk storage container 14 going from empty to full is acquired. The difference between the angle when the milk storage container 14 is not tilted and the angle at the tilt threshold is divided into several equal parts. The pressure data detected by the pressure sensor 24 at each tilt angle during the process of the milk storage container 14 going from empty to full is calibrated, and the detected pressure data is associated with the tilt angle data. In this way, the calibration of the pressure data and tilt angle data of the milk storage container 14 in the tilted state is completed, and a database is formed.

[0292] During the milk pumping process of the breast pump 10, the actual detected pressure data can be matched with the pressure data in the database by means of data fitting or taking similar values, and the tilt angle of the current milk storage container 14 can be obtained based on the pressure data.

[0293] Once the milk volume data and / or tilt angle data are determined, they can be displayed on the monitor of the breast pump 10, or sent to remote devices such as mobile phones, watches, and computers via the communication unit, so that users can observe the determined relevant data information.

[0294] Thus, the tilt state of the milk storage container 14 is determined based on the relationship between the pressure data detected by the pressure sensor 24.

[0295] In some embodiments of this application, the processing unit 30 is configured to determine the validity of the pressure data based on the tilt state information and / or to determine whether to trigger the alarm unit 40. If it is determined that the alarm unit 40 should be triggered, an alarm command is sent to the alarm unit 40.

[0296] When the tilt angle of the milk storage container 14 is too large, the pressure data detected by each pressure sensor 24 shows a significant difference, and the angle between the milk surface in the milk storage container 14 and the cross-section of the milk storage container 14 is also large. This leads to a large discrepancy between the milk volume data determined based on the pressure data and the actual milk volume in the milk storage container 14. Therefore, during the milk pumping operation, if the determined tilt angle exceeds the tilt threshold, the pressure data detected by the pressure sensor 24 is deemed invalid.

[0297] If the determined tilt angle exceeds the tilt threshold, the risk of milk overflowing from the milk storage container 14 increases. In this case, the processing unit 30 sends an alarm command to the alarm unit 40, triggering the alarm unit 40 to issue an alarm. The alarm issued by the alarm unit 40 can be an audible and visual alarm, or the alarm information can be displayed on the breast pump 10's screen, or it can be sent to a remote device such as a mobile phone, watch, or computer via the communication unit to alert the user remotely. After receiving the alarm information, the user can adjust their posture or the angle of the breast pump 10 to keep the tilt angle of the milk storage container 14 within the tilt angle threshold, thereby reducing the risk of milk overflowing from the milk storage container 14 and ensuring that the determined milk volume data meets the expected requirements.

[0298] Example 12

[0299] Please see Figures 1 to 2 and Figures 11 to 13 In some embodiments of this application, the detection unit 20 includes an air chamber assembly 25 and a pressure sensor 26, which detects the pressure data of the air chamber assembly 25. The air chamber assembly 25 is provided with a sealed space 253, and the air chamber assembly 25 simultaneously abuts against the support part 12 and the hanging part 15. Changes in the distance between the support part 12 and the hanging part 15 change the volume of the sealed space 253. The detected data is pressure data.

[0300] Please see Figures 11 to 13In some embodiments of this application, the mounting part 15 may be disposed inside the housing 11, one end of the pressure sensor 26 abuts against the support part 12, and the other end of the pressure sensor 26 abuts against the mounting part 15. At this time, the pressure sensor 26 provides support for the mounting part 15 between the support part 12 and the mounting part 15, and the force on the detection unit 20 is the air pressure generated by the mounting part 15 on the pressure sensor 26.

[0301] During the milk pumping process, the amount of milk in the milk storage container 14 gradually increases, which in turn increases the total weight of the milk storage container 14 and the milk inside, thereby increasing the pressure of the hook part 15 on the air pressure sensor 26, which in turn compresses the gas in the sealed space 253, resulting in an increase in the air pressure in the sealed space 253. At this time, the air pressure data detected by the air pressure sensor 26 increases.

[0302] A database can be established by calibration, corresponding to air pressure data and milk volume data. Once the detection unit 20 detects the distance data, it can determine the milk volume in the milk storage container 14 by querying the database.

[0303] In this way, the amount of milk in the milk storage container 14 of the breast pump 10 is detected during the milk pumping process.

[0304] In some embodiments of this application, the unit air pressure data detected by the air pressure sensor 26 when the milk storage container 14 is loaded with a unit amount of milk can be used as a calculation constant, and then the change in the amount of milk in the milk storage container 14 can be calculated based on the change in air pressure data. Furthermore, the real-time amount of milk in the milk storage container 14 during the milk extraction process can be calculated based on the real-time air pressure data detected by the air pressure sensor.

[0305] Let Q1 be the air pressure data when the milk storage container 14 is empty, Q2 be the air pressure data after the milk storage container 14 is filled with a unit amount of milk, Q3 be the real-time air pressure data, a be the unit air pressure data, b be the unit milk volume, and x be the change in the milk volume in the milk storage container 14. Then:

[0306] a = Q2 - Q1;

[0307] x = [(Q3-Q1) / a]*b.

[0308] The pressure data Q1 when the milk storage container 14 is empty, Q2 when the milk storage container 14 is filled with a unit amount of milk, and Q3, which can be measured by the distance sensor 22, are as follows: Q1 and Q2 are constants after calibration, and Q3 is the real-time parameter measured by the distance sensor 22. The unit milk volume b is a constant set during calibration.

[0309] In this way, the change in milk volume in the milk storage container 14 can be calculated using the formula. Furthermore, the calibration process uses an empty milk storage container 14 as a reference; therefore, the change in milk volume in the milk storage container 14 represents the real-time milk volume. Thus, the milk volume in the milk storage container 14 of the breast pump 10 is monitored during the pumping process.

[0310] In some embodiments of this application, the air chamber assembly 25 includes an air chamber body 251 and a movable member 252. The movable member 252 and the air chamber body 251 enclose a sealed space 253, and the movable member 252 and the air chamber body 251 are slidably connected. One of the movable member 252 and the air chamber body 251 is directly or indirectly fixedly installed to one of the support portion 12 and the hanging portion 15, either directly or indirectly, through a transition structure. The other of the movable member 252 and the air chamber body 251 is directly or indirectly fixedly installed to the other of the support portion 12 and the hanging portion 15, either directly or indirectly, through a transition structure.

[0311] During the milk pumping process, the amount of milk in the milk storage container 14 gradually increases, thereby increasing the total weight of the milk storage container 14 and the milk inside, which in turn reduces the distance between the hook part 15 and the support part 12. As a result, the moving part 252 slides into the air chamber body 251, reducing the volume of the sealed space 253, which in turn compresses the gas in the sealed space 253, increasing the air pressure in the sealed space 253, i.e., increasing the air pressure data detected by the air pressure sensor 26.

[0312] A database can be established by calibration, corresponding to air pressure data and milk volume data. Once the detection unit 20 detects the distance data, it can determine the milk volume in the milk storage container 14 by querying the database.

[0313] In this way, the amount of milk in the milk storage container 14 of the breast pump 10 is detected during the milk pumping process.

[0314] In some embodiments of this application, the air chamber assembly 25 is an airbag.

[0315] During the milk pumping process, the amount of milk in the milk storage container 14 gradually increases, which in turn increases the total weight of the milk storage container 14 and the milk inside. This increases the pressure of the connecting part 15 on the air chamber assembly 25, which in turn reduces the volume of the sealed space 253 of the air chamber assembly 25. Consequently, the gas in the sealed space 253 is compressed, increasing the air pressure in the sealed space 253. As a result, the air pressure data detected by the air pressure sensor 26 increases.

[0316] A database can be established by calibration, corresponding to air pressure data and milk volume data. Once the detection unit 20 detects the distance data, it can determine the milk volume in the milk storage container 14 by querying the database.

[0317] In this way, the amount of milk in the milk storage container 14 of the breast pump 10 is detected during the milk pumping process.

[0318] Example 13

[0319] Please see Figures 1 to 2 and Figures 11 to 12 In some embodiments of this application, the number of air chamber assemblies 25 is at least three, and the air chamber assemblies 25 are arranged in a circular array along the central axis of the mounting interface 13. Each air chamber assembly 25 is equipped with at least one air pressure sensor 26 to detect the air pressure data in the sealed space 253 of the air chamber assembly 25.

[0320] By altering the force distribution between the bearing portion 12 and the connecting portion 15, the air pressure data detected by the air pressure sensors 26 in at least three air chamber assemblies 25 is changed. Furthermore, by calculating the median, calculating the average, fitting virtual data using the least squares method, and other data processing algorithms, the error caused by the different forces among the air chamber assemblies 25 is reduced based on the air pressure data detected by all the air pressure sensors 26, thereby improving the reliability and accuracy of the detection data acquired by the detection unit 20.

[0321] In some embodiments of this application, the processing unit 30 is configured to determine the tilt state of the milk storage container 14 based on the relationship between the air pressure data detected by the air pressure sensor 26.

[0322] During the pumping process of the breast pump 10, factors such as the user's posture can cause the breast pump 10 to tilt during operation, which in turn causes the milk storage container 14 to tilt. This results in an angle between the liquid level in the milk storage container 14 and the cross-section of the milk storage container 14, leading to inaccurate and excessively deviated milk volume data. Furthermore, if the tilt angle of the milk storage container 14 is too large, milk may overflow from the milk storage container 14.

[0323] Since the gravity acting on the milk storage container 14 and the milk inside it is always vertically downward, when the milk storage container 14 is tilted, the direction of the gravity acting on the milk storage container 14 and the milk inside it will be at an angle to the normal of the hooking surface of the hooking part 15 of the milk storage container 14. This angle is the tilt angle of the milk storage container 14.

[0324] The milk storage container 14 is connected to the housing 11 via the air chamber assembly 25. Therefore, when the breast pump 10 tilts, the tilting trends of the housing 11 and the milk storage container 14 are different. The housing 11 tilts synchronously with the breast pump 10, while the tilting of the milk storage container 14 lags behind that of the housing 11, and the change in the tilt angle of the milk storage container 14 is less pronounced than that of the housing 11. Consequently, when the milk storage container 14 tilts, the forces acting on the air chamber assembly 25 at different locations will vary, resulting in differences in the air pressure data detected by the air pressure sensors 26 at different locations.

[0325] When the breast pump 10 tilts, causing the milk storage container 14 to tilt as well, the air chamber assembly 25 closer to the inside of the tilt direction experiences greater pressure, while the air chamber assembly 25 closer to the outside of the tilt direction experiences less pressure. At this time, the air pressure data detected by the pressure sensor 26 closer to the inside of the tilt direction increases, while the air pressure data detected by the pressure sensor 26 closer to the outside of the tilt direction decreases. Therefore, the tilt state of the milk storage container 14 can be determined based on this pattern. Furthermore, the degree of tilt of the milk storage container 14 can be judged based on the difference in air pressure data detected by the pressure sensors 26 closer to the inside and outside of the tilt direction.

[0326] By calibrating each data point individually, the air pressure data detected by the air pressure sensor 26 at different angles under different milk volumes in the milk storage container 14 can be obtained and a database can be formed.

[0327] During the milk pumping process, the real-time tilt angle of the milk storage container 14 can be determined by comparing the real-time data detected by the air pressure sensor 26 with the relevant data in the database.

[0328] In some embodiments of this application, when the milk storage container 14 is not tilted, the air pressure data detected by the air pressure sensor 26 can be acquired at each milk volume level during the process of the milk storage container 14 going from empty to full. When the tilt angle of the milk storage container 14 is at a tilt threshold, the air pressure data detected by the air pressure sensor 26 at each milk volume level during the process of the milk storage container 14 going from empty to full is acquired. The difference between the angle when the milk storage container 14 is not tilted and the angle at the tilt threshold is divided into several equal parts. The air pressure data detected by the air pressure sensor 26 at each milk volume level during the process of the milk storage container 14 going from empty to full is calibrated at each tilt angle, and the detected air pressure data is associated with the tilt angle data. In this way, the calibration of the air pressure data and tilt angle data of the milk storage container 14 in the tilted state is completed, and a database is formed.

[0329] During the milk pumping process, the actual detected air pressure data can be matched with the air pressure data in the database by means of data fitting or taking similar values, and the tilt angle of the current milk storage container 14 can be obtained based on the air pressure data.

[0330] Once the milk volume data and / or tilt angle data are determined, they can be displayed on the monitor of the breast pump 10, or sent to remote devices such as mobile phones, watches, and computers via the communication unit, so that users can observe the determined relevant data information.

[0331] Thus, the tilt state of the milk storage container 14 is determined based on the relationship between the air pressure data detected by the air pressure sensor 26.

[0332] In some embodiments of this application, the processing unit 30 is configured to determine the validity of the pressure data based on the tilt state information and / or to determine whether to trigger the alarm unit 40. If it is determined that the alarm unit 40 should be triggered, an alarm command is sent to the alarm unit 40.

[0333] When the tilt angle of the milk storage container 14 is too large, the pressure data detected by each pressure sensor 24 shows a significant difference, and the angle between the milk level in the milk storage container 14 and the cross-section of the milk storage container 14 is also large. This leads to a significant difference between the milk volume data determined based on the pressure data and the actual milk volume in the milk storage container 14. Therefore, during the milk pumping operation, if the determined tilt angle exceeds the tilt threshold, the air pressure data detected by the air pressure sensor 26 is deemed invalid.

[0334] If the determined tilt angle exceeds the tilt threshold, the risk of milk overflowing from the milk storage container 14 increases. In this case, the processing unit 30 sends an alarm command to the alarm unit 40, triggering the alarm unit 40 to issue an alarm. The alarm issued by the alarm unit 40 can be an audible and visual alarm, or the alarm information can be displayed on the breast pump 10's screen, or it can be sent to a remote device such as a mobile phone, watch, or computer via the communication unit to alert the user remotely. After receiving the alarm information, the user can adjust their posture or the angle of the breast pump 10 to keep the tilt angle of the milk storage container 14 within the tilt angle threshold, thereby reducing the risk of milk overflowing from the milk storage container 14 and ensuring that the determined milk volume data meets the expected requirements.

[0335] Example 14

[0336] Please see Figures 1 to 2 and Figure 13 In some embodiments of this application, the air chamber assembly 25 is a ring structure, and the air chamber assembly 25 is located between the support part 12 and the hanging part 15. The air pressure data in the sealed space 253 of the air chamber assembly 25 is detected by the air pressure sensor 16.

[0337] The air chamber assembly 25 includes an air chamber body 251 and a movable component 252. The movable component 252 and the air chamber body 251 enclose a sealed space 253, and the movable component 252 is slidably connected to the air chamber body 251. One of the movable component 252 and the air chamber body 251 is directly or indirectly fixedly installed to one of the support part 12 and the hanging part 15, either directly or indirectly, through a transition structure. The other movable component 252 and the other air chamber body 251 are directly or indirectly fixedly installed to the other of the support part 12 and the hanging part 15, either directly or indirectly, through a transition structure. Both the air chamber body 251 and the movable component 252 are annular structures. The inner diameter of the movable component 252 is larger than the inner diameter of the air chamber body 251, the inner diameter of the air chamber body 251 is larger than the diameter of the inlet of the milk storage container 14, the outer diameter of the movable component 252 is smaller than the outer diameter of the air chamber body 251, and the outer diameter of the air chamber body 251 is smaller than the diameter of the support part 12.

[0338] In some embodiments of this application, the mounting part 15 may be disposed inside the housing 11, one end of the pressure sensor 26 abuts against the support part 12, and the other end of the pressure sensor 26 abuts against the mounting part 15. At this time, the pressure sensor 26 provides support for the mounting part 15 between the support part 12 and the mounting part 15, and the force on the detection unit 20 is the air pressure generated by the mounting part 15 on the pressure sensor 26.

[0339] During the milk pumping process, the amount of milk in the milk storage container 14 gradually increases, which in turn increases the total weight of the milk storage container 14 and the milk inside, thereby increasing the pressure of the hook part 15 on the air pressure sensor 26, which in turn compresses the gas in the sealed space 253, resulting in an increase in the air pressure in the sealed space 253. At this time, the air pressure data detected by the air pressure sensor 26 increases.

[0340] A database can be established by calibration, corresponding to air pressure data and milk volume data. Once the detection unit 20 detects the distance data, it can determine the milk volume in the milk storage container 14 by querying the database.

[0341] In this way, the amount of milk in the milk storage container 14 of the breast pump 10 is detected during the milk pumping process.

[0342] Example 15

[0343] On the other hand, please see Figure 17 In some embodiments of this application, this application also provides a milk quantity detection method, including the following steps:

[0344] Obtain test data after milk is filled into milk storage container 14;

[0345] The amount of milk in the milk storage container 14 is determined based on the test data.

[0346] During the pumping process of the breast pump 10, milk flows into the milk storage container 14, which holds the milk pumped by the breast pump 10. As the pumping continues, the amount of milk in the milk storage container 14 gradually increases, thus increasing the total weight of the container and the milk it holds. In this situation, by placing the detection unit 20 at the junction of the milk storage container 14 and the housing 11, the detection data detected by the detection unit 20 changes as the amount of milk in the milk storage container 14 increases. This allows for the determination of changes in the milk volume data within the milk storage container 14 based on these changes. The milk volume data includes one or more of the following: the volume of milk in the milk storage container 14, its weight, and the percentage of the milk volume relative to the total volume of the milk storage container 14.

[0347] Thus, the amount of milk in the milk storage container 14 is determined by the detection data detected by the detection unit 20, thereby enabling the detection of the amount of milk in the milk storage container 14 of the breast pump 10 during the milk pumping process.

[0348] In some embodiments of this application, the detection data is one or more of distance data, capacitance data, pressure data, and air pressure data.

[0349] Example 16

[0350] Please see Figure 21 In some embodiments of this application, the following steps are included before the step of obtaining the detection data after the milk storage container 14 is filled with milk:

[0351] The test data are calibrated.

[0352] In some embodiments of this application, the step of calibrating the detection data includes the following steps:

[0353] Step 1: Obtain milk emptying detection data when milk storage container 14 is empty;

[0354] Step 2: Measure out a unit volume of milk;

[0355] Step 3: Pour the milk of a unit volume into the milk storage container 14;

[0356] Step 4: Obtain unit test data when the milk storage container 14 contains a unit volume of milk;

[0357] Step 5: Measure out a unit volume of milk;

[0358] Step 6: Pour the milk (per unit volume) into milk storage container 14;

[0359] Step 7: Obtain the cumulative test data when the milk storage container 14 contains a cumulative unit volume of milk;

[0360] Step 8: Repeat steps 5 through 7 until the milk storage container 14 is full.

[0361] In some embodiments of this application, after the milk storage container 14 is filled, the following steps are also included:

[0362] Step 9: Determine the milk fullness test data based on the cumulative test data after the milk storage container 14 is full.

[0363] The test data is calibrated through successive calibration to establish a database that corresponds to the test data and the milk volume data. When the detection unit 20 detects the test data, it can determine the milk volume in the milk storage container 14 by querying the database.

[0364] In this way, the amount of milk in the milk storage container 14 of the breast pump 10 is detected during the milk pumping process.

[0365] The detected milk volume data can be displayed on the monitor of the breast pump 10, and can also be sent to remote terminals such as mobile phones, watches, and computers through the communication unit. The milk volume data can be displayed to the user remotely, so that the user can understand the milk volume data in the milk storage container 14 in real time during the milk pumping process.

[0366] When the milk storage container 14 is detected to be full, the processing unit 30 can send an alarm command to the alarm unit 40, triggering the alarm unit 40 to issue an alarm. The alarm issued by the alarm unit 40 can be an audible and visual alarm, or the alarm information can be displayed on the display of the breast pump 10, or it can be sent to a remote terminal such as a mobile phone, watch, or computer via the communication unit, so that the user can be notified remotely that the milk storage container 14 is full.

[0367] Example 17

[0368] Please see Figure 22 In some embodiments of this application, the step of calibrating the detection data includes the following steps:

[0369] Step 1: Obtain milk emptying detection data when milk storage container 14 is empty;

[0370] Step 2: Obtain milk fullness detection data after milk storage container 14 is filled with milk;

[0371] Step 3: Calculate the difference between the milk fullness test data and the milk emptyness test data;

[0372] Step 4: Divide the difference into N equal parts, with each part being a unit difference;

[0373] Step 5: Determine the cumulative test data based on the sum of the milk empty detection data and the differences of n units;

[0374] Where N and n are both natural numbers, N≥1, 1≤n≤N.

[0375] Measure the milk empty data t when the milk storage container 14 is empty and the milk full data T when the milk storage container 14 is full of milk. Then calculate the difference S between the milk full data T and the milk empty data t. Divide the difference S into N equal parts, each part being a unit difference s. Based on the milk empty data t when the milk storage container 14 is empty, determine the cumulative data K according to the n unit differences s. The cumulative data K is the real-time milk volume data in the milk storage container 14. The calculation formula is K = t + ns, s = S / N, S = Tt. K = t + n(Tt) / N.

[0376] In some embodiments of this application, the step of obtaining detection data after filling the milk storage container 14 with milk includes the following steps:

[0377] Two or more test data were obtained at the same time point after milk was filled into milk storage container 14.

[0378] By comprehensively analyzing two or more detection data, the accuracy of detection can be improved.

[0379] In some embodiments of this application, after the step of acquiring two or more detection data after the milk storage container 14 is filled with milk at the same time point, the following steps are further included:

[0380] To obtain the relationship between detection data at the same time point.

[0381] The data between the test data includes the differences, mean, difference of squares, median, etc.

[0382] Please see Figure 18 In some embodiments of this application, after the step of obtaining the relationship between detection data at the same time point, the following steps are further included:

[0383] The tilt state of the milk storage container 14 is determined based on the relationship between the detection data at the same time point.

[0384] The tilt state of the milk storage container 14 is determined based on the difference between the detection data. Once the milk volume data and / or tilt angle data are determined, they can be displayed on the monitor of the breast pump 10, or sent to remote terminals such as mobile phones, watches, and computers via the communication unit, so that users can observe the determined relevant data information.

[0385] Please see Figure 19 In some embodiments of this application, after the step of obtaining the relationship between detection data at the same time point, the following steps are further included:

[0386] The validity of the test data is determined by the relationship between the test data at the same time point.

[0387] When the test data is determined to be invalid based on the relationship between the test data, the test data is not recorded. Instead, the invalid test data is marked and displayed on the display of the breast pump 10. It can also be sent to remote devices such as mobile phones, watches, and computers via the communication unit so that users can observe the determined relevant data information.

[0388] Please see Figure 20 In some embodiments of this application, after the step of obtaining the relationship between detection data at the same time point, the following steps are further included:

[0389] Determine whether alarm unit 40 has been triggered;

[0390] If it is determined that alarm unit 40 needs to be triggered, then an alarm command is sent to alarm unit 40.

[0391] When the tilt angle of the milk storage container 14 is too large, the differences between the distance data detected by the various distance sensors 22 are significant, and the angle between the liquid level of the milk in the milk storage container 14 and the cross-section of the milk storage container 14 is also large. This leads to a large difference between the milk volume data determined based on the distance data and the actual milk volume in the milk storage container 14. Therefore, during the milk pumping operation, if the determined tilt angle exceeds the tilt threshold, the distance data detected by the distance sensors 22 is deemed invalid.

[0392] If the determined tilt angle exceeds the tilt threshold, the risk of milk overflowing from the milk storage container 14 increases. In this case, the processing unit 30 sends an alarm command to the alarm unit 40, triggering the alarm unit 40 to issue an alarm. The alarm issued by the alarm unit 40 can be an audible and visual alarm, or the alarm information can be displayed on the breast pump 10's screen, or it can be sent to a remote device such as a mobile phone, watch, or computer via the communication unit to alert the user remotely. After receiving the alarm information, the user can adjust their posture or the angle of the breast pump 10 to keep the tilt angle of the milk storage container 14 within the tilt angle threshold, thereby reducing the risk of milk overflowing from the milk storage container 14 and ensuring that the determined milk volume data meets the expected requirements.

[0393] On the other hand, this application also provides a computer-readable storage medium storing computer instructions, which, when executed, perform the milk quantity detection method described in the claims.

[0394] Example 18

[0395] Please see Figures 15 to 16In some embodiments of this application, a breast pump system is provided, including a breast pump 10 and accessories. The breast pump 10 includes a housing 11 and a milk storage container 14. A detection unit 20 is provided on the breast pump 10 or the accessories. When the breast pump 10 is combined with the accessories, the detection unit 20 is triggered to start a detection action, or the breast pump 10 is combined with the accessories and enters a detectable state, which is then triggered by other actions, such as tapping, voice, triggering a button, etc.

[0396] After the breast pump 10 is combined with the accessories, the detection unit 20 detects the detection data of the breast pump 10, and then determines the milk volume data in the breast pump 10 based on the detection data.

[0397] The detection data can be weight data. The weight of the breast pump 10 after it is filled with milk is detected by the detection unit 20. Then, the weight of the breast pump 10 itself is subtracted from the weight of the breast pump 10 after it is filled with milk, so as to determine the weight of the milk in the breast pump 10. In this way, the amount of milk in the breast pump 10 is determined.

[0398] In some embodiments of this application, the detection unit 20 is a weight detection module 50, and the accessories are a dust cover 17 or a support base 18.

[0399] Please see Figure 15 In some embodiments of this application, the weight detection module 50 is disposed on one of the breast pump 10 and the dust cover 17. The breast pump 10 and the dust cover 17 are combined, and the dust cover 17 is placed on a flat surface. The weight detection module 50 can detect the weight data of the breast pump 10 after it is filled with milk. Then, the weight of the breast pump 10 is determined by subtracting the weight of the breast pump 10 itself from the weight of the breast pump 10 after it is filled with milk. In this way, the amount of milk in the breast pump 10 is determined.

[0400] Please see Figure 16 In some embodiments of this application, the weight detection module 50 is disposed on one of the breast pump 10 and the support base 18. The support base 18 is placed on a flat surface. When the breast pump 10 is placed on the support base 18, the weight data of the breast pump 10 after being filled with milk can be detected by the weight detection module 50. Then, the weight of the breast pump 10 is determined by subtracting the weight of the breast pump 10 itself from the weight of the breast pump 10 after being filled with milk. In this way, the amount of milk in the breast pump 10 is determined.

[0401] In some embodiments of this application, the weight detection module 50 is disposed on one of the breast pump 10 and the charging base. When the charging base is placed on a flat surface, the weight detection module 50 can detect the weight data of the breast pump 10 after it is filled with milk. Then, the weight of the breast pump 10 is determined by subtracting the weight of the breast pump 10 itself from the weight of the breast pump 10 after it is filled with milk. In this way, the amount of milk in the breast pump 10 is determined.
