Description

Breast pump, storage medium, detection method, control method and device Technical Field

[0001] The present invention relates to the field of maternal and infant products, and in particular to a breast pump, a storage medium, a detection method, a control method and a device. Background Art

[0002] With the development of society, people's material lives are becoming increasingly abundant, and the pace of life is accelerating. Childbirth is an essential part of human reproduction. However, in this fast-paced society, many working women find it difficult to breastfeed their infants according to their needs. Furthermore, as living conditions improve, lactating women often produce excess breast milk. Therefore, breast milk is collected and stored to ensure that it can be breastfed at any time. Excess breast milk can also be stored to ensure effective breastfeeding for infants in situations where a mother's milk production decreases or when it is inconvenient for the mother to breastfeed.

[0003] As a portable and convenient breast pumping device, breast pumps are attracting more and more attention. Their functions and structures are also constantly being improved so that breast pumps can complete the milk pumping operation more safely and efficiently and improve the user experience.

[0004] Some models of breast pumps are more discreet devices that can complete the milk extraction operation under the cover of the user's clothing, making them suitable for a wider range of occasions and providing better privacy protection. However, while protecting the user's privacy, breast pumps can make it inconvenient for the user to observe the amount of breast milk being extracted by the breast pump, and to promptly observe or understand the current condition of the breasts. As a result, during the milk extraction process, the user is unable to grasp the amount of breast milk being extracted or to match the appropriate milk extraction mode. Breast milk often overflows from the milk storage container. Since it is often difficult for the human body to maintain the same posture during the milk extraction process, and since everyone's body habits are different, the milk bowl often tilts or shakes, causing the milk in the bowl to tilt relative to the milk container or to create undulating waves, thereby increasing the risk of milk overflowing from the bowl.

[0005] Most of the breast pumps in the prior art have relatively fixed modes and relatively single functions, which are not very adaptable to users' needs for different modes.

[0006] Breast pumps in the prior art are also prone to problems such as improper installation, which may cause problems such as malfunction or milk leakage.

[0007] The breast pumps in the prior art have a single mode and cannot be adaptively adjusted according to the breast milk status of the human body, so the milk output efficiency is low and needs to be improved.

[0318] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0319] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0320] Please refer to FIG. 1 , in which the breast pump 1 includes a milk storage container portion 50 , a negative pressure mechanism 20 and a breast milk collecting portion 10 .

[0321] The breast milk collecting portion is also called a breast shield 10 .

[0322] In some embodiments, the breast shield 10 may include a flange 11 and may further include a diaphragm support integrally formed with the flange, the diaphragm support being used to support the diaphragm; the flange may include an end that fits the breast and may further include an end that communicates with a milk storage container portion or a milk storage cavity. Preferably, the end that communicates with the milk storage container portion or the milk storage cavity may be a nipple channel.

[0323] In some embodiments, one end of the breast milk collection portion is attached to the breast, and the other end is fluidically connected to the milk storage container portion. The milk storage container is used to store the breast milk collected by the breast milk collection portion. The breast milk collection portion and the interior of the milk storage container portion form an internal cavity for breast milk circulation or storage.

[0324] The negative pressure mechanism can directly or indirectly apply negative pressure to the internal cavity, so that breast milk is sucked into the milk storage container for storage;

[0325] In some embodiments, the milk storage container portion 50 may also be referred to as a milk storage cavity, and may include a milk cap, a milk bowl, a milk bottle, etc., which is not limited in this application.

[0326] In some embodiments, the breast pump further includes a detection unit 40 (not shown in the figure, which may be a detector) and a control unit 30 (not shown in the figure), wherein the detection unit is configured to obtain detection parameters; and the control unit is configured to control the breast pump.

[0327] In some embodiments, the detection unit 40 is provided on the breast pump 1 and can detect, sense or obtain one or more of installation status, distance sensing, volume, flow, weight, pressure, liquid level, breast status parameters, user preset parameters or historical data parameters.

[0328] In some embodiments, a detection unit, such as an optical detection unit, needs to be installed on the breast pump, preferably installed on the part that does not contact the breast milk, for example, it can be set inside the shell 80 or the main unit 2 (not shown in the figure), and more preferably, it is set on the outer wall, for example, the outer wall of the milk storage container part, or the outer wall of the main unit, or the non-breast milk side that indirectly applies negative pressure.

[0329] In some embodiments, the host 2 includes a control unit 30 and a negative pressure mechanism 20 .

[0330] In the negative pressure mechanism 20 described in the breast pump 1 of the present application, the power structure for generating negative pressure includes but is not limited to a piezoelectric pump, a diaphragm pump, a hydraulic pump, a mechanical pump, etc., which can be directly connected to cause negative pressure inside the breast shield, or can be used to indirectly cause negative pressure inside the breast shield 10 by transmitting the negative pressure to a liquid barrier such as a diaphragm or an air bag; breast milk is introduced into the milk storage container portion 50 for storage through the negative pressure.

[0331] In some embodiments, the negative pressure mechanism may apply negative pressure manually or electrically.

[0332] In some embodiments, the aforementioned communication causing negative pressure inside the breast shield means that the air path of the negative pressure driving part is directly connected to the internal cavity; the aforementioned indirect generation of negative pressure by transmitting the negative pressure to the barrier member means that the negative pressure driving mechanism blocks the milk and the negative pressure driving member through a deformable diaphragm or a sac or an air-permeable but liquid-impermeable barrier material;

[0333] In some embodiments, the internal cavity 70 (not shown) can be an internal cavity formed by direct communication between the breast shield 10 and the milk storage container portion 50, or a cavity formed by communication between the breast shield 10 and the milk storage container portion 50 via other pipes.

[0334] In some embodiments, the breast pump further includes a control system, which may be installed on the main unit or in the form of a separate handheld remote controller, allowing the user to directly control the operation of the breast pump.

[0335] In some embodiments, the breast pump further comprises a power supply module; the power supply module may be a battery, a dry cell, an electric wire, etc.

[0336] For ease of description, in some embodiments, the detection unit 40 is also referred to as a detection element 40 , and the breast milk collecting portion 10 is also referred to as a breast shield 10 .

[0337] In the first embodiment.

[0338] In this embodiment, as shown in FIG2 , the main components of a breast pump 1 include a milk storage container 50, a flange 11, and a main unit 2. Generally, the main unit 2 and flange 11 are detachable from the milk storage container 50, allowing mothers to store the milk in the milk storage container 50 and clean the milk storage container 50 and flange 11 immediately after expressing milk, thereby achieving optimal user convenience. However, the primary user group for this type of product is postpartum mothers, a group that includes both working mothers and housewives. Therefore, their use is affected by the environment. For example, working mothers may be constrained by time constraints and work environments, while housewives may be affected by various daily responsibilities, such as crying infants and busy housework. These environments can easily distract mothers or lead to emotional instability while using the breast pump 1, resulting in improper installation of the breast pump 1. This can lead to milk flowing into the main unit 2, damaging it, or spilling milk, contaminating the milk and staining clothing, causing significant user inconvenience.

[0339] The embodiments of the present application provide a method for detecting whether the breast pump 1 is properly installed and a breast pump 1 using the method. The method combines detection signals of multiple detection units to determine whether the flange 11, the diaphragm 60, and the main unit 2 are properly installed on the milk storage container portion 50, thereby ensuring that the breast pump 1 can be installed properly without being affected by external factors, improving the working stability of the breast pump 1, and ensuring that the user can use the breast pump 1 more conveniently and with a higher experience.

[0340] 2-6 , the breast pump 1 provided in this embodiment includes a milk storage container portion 50, a main unit 2, a flange 11, and a diaphragm 60 mounted on the flange 11; wherein, the main unit 2 and the flange 11 are both detachably assembled on the milk storage container portion 50, the milk storage container portion 50 is used to hold the sucked milk, the main unit 2 is used to generate suction, control the suction force, the milk suction speed and time, and record the milk suction data, etc., and the diaphragm 60 plays the role of generating suction in the breast pump 1. Through the back-and-forth movement of the diaphragm 60, a negative pressure is generated inside the breast pump 1, thereby sucking milk out of the breast. In addition, during the milk suction process, the diaphragm 60 can prevent the milk from flowing back into the breast, ensuring that the milk is smoothly sucked out. In this embodiment, the main unit 2 includes a negative pressure mechanism 20 for generating negative pressure through suction, and a control unit 30 for controlling the negative pressure mechanism 20. The negative pressure mechanism 20 is used to generate suction on the user's breast via a flange 11, extracting milk and discharging it into a milk storage container 50. The flange 11 is used to connect to and securely engage the milk storage container 50. When the breast pump 1 is in use, the flange 11 fits snugly against the breast, ensuring there is no gap between the nipple and the milk storage container 50. The suction generated by the main unit 2 allows milk from the breast to be drawn through the flange 11 and collected in the milk storage container 50. Because the flange 11 directly contacts the nipple and breast, in this embodiment, it is made of a soft, non-toxic, and non-irritating material to reduce friction and irritation on the nipple and breast.

[0341] As shown in Figures 2-8, preferably, in the above embodiment, a first detection unit 131 is provided between the flange 11 and the milk storage container portion 50. The first detection unit 131 is configured to generate a first signal when the flange 11 is not properly installed. It is understandable that the above process needs to be implemented after the main unit 2 is installed on the milk storage container portion 50. Then, the control unit 30 of the main unit 2 can determine whether the flange 11 is properly installed on the milk storage container portion 50. When the flange 11 is not yet installed on the milk storage container portion 50, the control unit 30 is sensed by a preset sensor so that the control unit 30 does not detect the first signal during this process. Further, when the sensor senses that the flange 11 reaches the milk storage container portion 50 and begins to be installed, the control unit 30 starts to detect the first signal. When the control unit 30 detects the generation of the first signal, it can automatically generate and issue a first prompt message to prompt the user to reinstall the flange 11 and stop pumping milk.

[0342] It can be understood that the overall operation of the breast pump 1 in this embodiment is controlled by the control unit 30 in the host 2. The control unit 30 may be a central control unit CPU, or an application-specific integrated circuit ASIC (Application Specific Integrated Circuit), or one or more integrated circuits configured to implement the embodiments of the present invention, which are not limited here.

[0343] It is understandable that in the above solution, the function of sensing a signal from the control unit 30 by the preset sensor so that the control unit 30 determines whether the flange 11 contacts the milk storage container portion 50 to start installation or removal from the milk storage container portion 50 can be achieved using different types of sensors such as acoustic sensors and photoelectric sensors. When the flange 11 is completely removed from the milk storage container portion 50, the sensor can sense a signal from the control unit 30, thereby similarly causing the control unit 30 to not detect the first signal. That is, when the flange 11 is not installed on the milk storage container portion 50 or is completely removed from the milk storage container portion 50 and thus does not contact the milk storage container portion 50, the control unit 30 does not detect the first signal in both cases. This will not be described in detail here.

[0344] Referring to Figures 2-6 , preferably, in the above embodiment, the breast pump 1 further includes a second detection unit 132 and a third detection unit 133. The second detection unit 132 is configured to generate a second signal when the main unit 2 is not properly installed, and also trigger the third detection unit 133 to generate a third signal when the flange 11 is not properly installed. The control unit 30 is further configured to detect the second and third signals and automatically generate a prompt message, and / or stop pumping milk and / or automatically shut down the main unit 2. It will be appreciated that the above process is implemented using the same principle as determining whether the flange 11 and the milk storage container portion 50 are properly installed, i.e., the control unit 30 senses a signal via a preset sensor. When the main unit 2 is not installed on the milk storage container portion 50 or is completely separated from the milk storage container portion 50, the control unit 30 does not detect the second signal. This will not be further described herein.

[0345] In addition, the third detection unit 133 is configured to generate a third signal when the diaphragm 60 is not properly installed. It can be understood that when the flange 11 is not properly installed on the milk storage container portion 50 and the first signal is generated, the diaphragm 60 installed on the flange 11 will be driven and thus not properly installed, thereby triggering the third detection unit 133 to generate the third signal.

[0346] 7-8 , preferably, in the above embodiment, there are two assembly options for the user when assembling the breast pump 1: one is to first assemble the main unit 2 onto the milk storage container 50, and then assemble the flange 11 onto the milk storage container 50 to complete the assembly of the breast pump 1; the other is to first assemble the flange 11 onto the milk storage container 50, and then assemble the main unit 2 onto the milk storage container 50 to complete the assembly of the breast pump 1. In both assembly options, the control unit 30 needs to detect the first signal, the second signal, and the third signal. During operation after the breast pump 1 is turned on, the control unit 30 of the main unit 2 detects whether the first signal, the second signal, and the third signal are obtained. If the first signal and the second signal are not obtained, it is determined that the main unit 2 and the flange 11 are properly installed on the milk storage container 50, and the operation can continue.

[0347] Preferably, if the control unit 30 receives the first signal, it deems that the flange 11 is not properly installed on the milk storage container portion 50. In this case, the control unit 30 issues a first prompt message to prompt the user to reinstall the flange 11 and stop pumping. Furthermore, if the control unit 30 receives the second signal, it deems that the main unit 2 is not properly installed on the milk storage container portion 50, and deems that the flange 11 is not installed on the milk storage container portion 50. In this case, the control unit 30 automatically generates and issues a second prompt message to prompt the user to reinstall the main unit 2 and stop pumping. If the control unit 30 receives the second signal after receiving the first signal, it deems that both the main unit 2 and the flange 11 are not properly installed on the milk storage container portion 50, and prompts are required in sequence.

[0348] Moreover, in the above process, the generation of the first signal indicates that the flange 11 is not properly installed, so that the diaphragm 60 installed on the flange 11 is also not properly installed, thereby triggering the third detection unit 133 to generate a third signal. At this time, the control unit 30 will detect the first signal and the third signal. When the control unit 30 detects the third signal, it means that the flange 11 is not properly installed on the milk storage container portion 50 at this time, so that the diaphragm 60 installed on the flange 11 is also not properly installed. The control unit 30 will automatically generate and issue a prompt message and automatically shut down the main unit 2. This situation applies to the use of the breast pump and will be described in detail later.

[0349] 3-6 , according to the above solution, it can be understood that the flange 11 in this embodiment can be used as a cover on one side of the milk storage container portion 50. A breast shield is provided on the flange 11. By installing the flange 11 on the milk storage container portion 50, the milk storage container portion 50 is buckled. However, in actual use, the user may accidentally touch the flange 11 when using the breast pump 1, causing the flange 11 to move on the milk storage container portion 50 and thus not be installed in place, and causing the diaphragm 60 installed on the flange 11 to also not be installed in place, which will easily cause the milk storage container portion 50 to leak. In addition, in another embodiment, the flange 11 can be used to prevent the milk storage container portion 50 from leaking. In this case, during normal use, the user may remove the flange 11 from the milk storage container portion 50 to remove milk without shutting down the main unit 2 in advance, thereby further opening the bowl of the milk storage container portion 50. In addition, both of the above situations may cause milk to spill from the milk storage container portion 50, causing milk contamination and easily staining clothes. Moreover, when the flange 11 is removed from the milk storage container portion 50 together with the diaphragm 60, the milk in the milk storage container portion will be sucked back into the main unit 2 due to the lack of the diaphragm 60 to block it, causing damage to the main unit 2. Therefore, the third detection unit 133 is provided to prevent this situation.

[0350] In another embodiment, the breast pump further comprises a fourth detection unit, which is configured to generate a fourth signal when detecting that the diaphragm 60 is not properly installed. It is understandable that in one case, when the flange 11 is properly installed on the milk storage container portion 50, the diaphragm 60 is not properly installed, so that after the flange 11 is installed on the milk storage container portion 50, the diaphragm 60 is not properly installed between the milk storage container portion 50, thereby triggering the fourth detection unit to generate the fourth signal; it is understandable that the third detection unit 133 in the previous embodiment is configured to generate the third signal when the diaphragm 60 is not properly installed. Therefore, the fourth detection unit in this embodiment is equivalent to the third detection unit 133 of the previous embodiment, and is therefore not described in detail. For structural implementation drawings, please refer to Figures 3 to 6. Furthermore, when the fourth detection unit generates the fourth signal, the control unit 30 detects the first signal and the fourth signal. When the control unit 30 detects the fourth signal, it indicates that the flange 11 is not properly installed on the milk storage container portion 50, so that the diaphragm 60 installed on the flange 11 is also not properly installed. The control unit 30 automatically generates and issues a fifth prompt message, stops sucking milk, and automatically shuts down the main unit 2 to prevent milk from flowing back.

[0351] Specifically, when the control unit 30 detects the third signal, it indicates that the breast pump 1 has encountered one of the above two situations during use. The control unit 30 configures the signal level of the third signal, that is, the signal level of the third signal is divided into "A" and "B", and the control unit 30 determines whether the signal level of the third signal is "A" or "B" to perform different corresponding mechanisms. That is, when the control unit 30 detects that the signal level of the third signal is "A", it indicates that the user may have accidentally touched the flange 11, causing the position of the flange 11 on the milk storage container part 50 to move, so that the flange 11 is not installed in place, and the diaphragm 60 installed on the flange 11 is also not installed in place, causing the milk storage container part 50 to leak. At this time, the control unit The control unit 30 will automatically generate and issue a third prompt message to inform the user that the milk storage container portion 50 is leaking, stop sucking milk, and then shut down the main unit 2 to prevent milk from spilling out or entering the main unit 2. In addition, when the control unit 30 detects that the signal level of the third signal is "B", it means that the user has removed the flange 11 from the milk storage container portion 50 to perform further operations such as taking milk without shutting down the main unit 2 in advance. In this case, the user has removed the flange 11 together with the diaphragm 60 from the milk storage container portion 50, causing the bowl of the milk storage container portion 50 to open. At this time, the control unit 30 will automatically generate and issue a fourth prompt message to inform the user that the main unit 2 is not shut down, and at the same time shut down the main unit 2 to prevent milk from spilling out or entering the main unit 2.

[0352] In one embodiment, the first detection unit 131 includes a Hall sensor, and the Hall sensor is disposed between the flange 11 and the milk storage container portion 50 , so as to sense whether the flange 11 is in place when it is installed on the milk storage container portion 50 .

[0353] Referring to Figures 3-4 , the first detection unit 131 specifically includes a sensing element disposed at the bottom of the milk container portion 50, away from the mounting location of the main unit 2, and a triggering element disposed at the top of the milk container portion 50, closer to the mounting location of the main unit 2. In this embodiment, the triggering element is a magnet, and the sensing element is a Hall effect sensor disposed on the milk container portion 50. The triggering element and the sensing element are disposed opposite each other on the milk container portion 50, enabling the Hall effect sensor to generate different Hall effect signals, i.e., first signals, based on changes in the magnetic force of the magnet. When the flange 11 is properly installed on the milk container portion 50, one side of the flange 11 blocks the triggering element, causing the triggering element to change the magnetic force signal sent to the sensing element. The first detection unit 131 detects that the change in the magnetic force signal matches a preset value for magnetic force change when the flange 11 is properly installed, indicating that the flange 11 is properly installed. If the flange 11 is not properly installed on the milk container portion 50, resulting in the magnet not being blocked, the triggering element to the sensing element does not change the magnetic force signal, and the first detection unit 131 then generates the first signal. There are many ways to determine the relative position of the flange 11 and the milk storage container portion 50 using the Hall sensor and the magnet, which are only given as examples and are not limited in the embodiments of the present application.

[0354] In another embodiment, the first detection unit 131 includes a photoelectric sensor, and by arranging the photoelectric sensor between the main unit 2 and the flange 11 , the purpose is also to sense whether the flange 11 is in place when it is installed on the milk storage container portion 50 .

[0355] As shown in FIG5-5, specifically, between the main unit 2 and the flange 11, including between the flange 11 and the milk storage container 50, it can be understood that the types of photoelectric sensors that can be used in this embodiment include: light-shielding photoelectric sensors, laser sensors, transmission photoelectric sensors and other different types of sensors; further, when using a light-shielding photoelectric sensor, the light-shielding photoelectric sensor can be installed on the milk storage container 50, and the number of candela that the flange 11 blocks when it is installed in place is preset, and the amount of light blocked by the flange 11 is detected to determine the position of the flange 11 on the milk storage container 50, thereby determining whether it is installed in place. When the flange 11 is in the milk storage container, the position of the flange 11 on the milk storage container 50 is determined. When the candela value of the light blocked by the part 50 meets the preset value, it indicates that the flange 11 is properly installed. When using a laser sensor, the laser sensor can be installed at the position where the flange 11 passes on the milk storage container part 50, and the reflection time of the light when the flange 11 is properly installed is preset. After the flange 11 is installed in the milk storage container part 50, the reflection length of the light is changed, thereby changing the reflection time of the light to determine whether the flange 11 is properly installed. When the changed light reflection time of the flange 11 meets the preset value, it indicates that the flange 11 is properly installed. The transmission type photoelectric sensor determines whether the flange 11 is properly installed by detecting the intensity of the transmitted light after the light passes through the flange 11.

[0356] There are various ways to use a photoelectric sensor to determine the relative position of the flange 11 and the milk storage container portion 50. These are merely examples and are not intended to be limiting in this embodiment. Therefore, the first detection unit 131 and the second detection unit 132 described above can be based on magnetic induction, photoelectric induction, mechanical switches, or other structures. These are merely examples and are not intended to be limiting in this embodiment.

[0357] In one embodiment, the second detection unit 132 includes a photoelectric sensor, which is disposed between the main unit 2 and the milk storage container 50 , so as to sense whether the main unit 2 is in place when it is mounted on the milk storage container 50 .

[0358] The above describes the installation location and operating principle of the first detection unit 131. The second detection unit 132 differs from the first detection unit 131 only in that the second detection unit 132 is located between the main unit 2 and the milk storage container 50 and is used to detect whether the main unit 2 is properly installed in the milk storage container 50. The rest of the description is similar to the first detection unit 131, and can be referred to the description of the first detection unit 131. It will not be repeated here.

[0359] In one embodiment, the third detection unit 133 and the fourth detection unit both include pressure sensors, which are disposed on the diaphragm 60 between the milk storage container portion 50 and the flange 11. The purpose is to promptly alert the user and automatically initiate a response mechanism when the flange 11 is improperly installed on the milk storage container portion 50 or is displaced, or when the flange 11 is directly removed from the milk storage container portion 50 during use.

[0360] Specifically, during the installation process, the pressure sensor is provided on the milk storage container portion 50 and is located in the negative pressure chamber 260 formed between the milk storage container portion 50 and the diaphragm 60. It can be understood that the air pressure state of the negative pressure chamber 260 formed between the milk storage container portion 50 and the diaphragm 60 is different during normal operation and when it stops working. The air tightness of the negative pressure chamber 260 is detected and sensed by the pressure sensor. When the diaphragm 60 is not properly installed on the milk storage container portion 50, the pressure sensor detects that the air pressure in the negative pressure chamber 260 does not reach the preset standard, and therefore determines that the negative pressure chamber 260 is not in a sealed state, and further confirms that the diaphragm 60 is not properly installed, thereby feeding back a fourth signal. After receiving the fourth signal, the control unit 30 automatically generates and issues a fifth prompt message and stops the milk pumping operation.

[0361] In another embodiment, the fourth detection unit further includes a touch sensor, that is, when the diaphragm is not installed in place, the touch sensor sends a fourth signal to the control unit 30, and the control unit 30 performs the next step, which will not be described in detail here.

[0362] Specifically, during use, the pressure sensor is provided on the milk storage container portion 50 and is located in the negative pressure chamber 260 formed between the milk storage container portion 50 and the diaphragm 60. It is understandable that the air pressure state of the negative pressure chamber 260 formed between the milk storage container portion 50 and the diaphragm 60 is different when it is in normal operation and when it is stopped. The air tightness of the negative pressure chamber 260 is detected and sensed by the pressure sensor. When the flange 11 is displaced on the milk storage container portion 50 or when the flange 11 is directly removed from the milk storage container portion 50, the diaphragm 60 must be displaced along with the flange 11. The pressure sensor detects the change in the air pressure in the negative pressure chamber 260 and feeds back a third signal. When the control unit 30 detects the third signal, the pressure sensor detects the signal strength of the air pressure value in the negative pressure chamber 260, and divides the signal level of the third signal into "A" level and "B" level. The "A" level signal represents a weak signal, indicating that the air pressure in the negative pressure chamber 260 is still maintained in a certain range, which is different from the external atmospheric pressure, thereby indicating that the negative pressure chamber 260 is leaking, further indicating that the flange 11 is still in the milk storage capacity. The control unit 30 will automatically generate and issue a third prompt message to the user that the diaphragm 60 is not properly installed and the main unit 2 is not turned off, and stop sucking milk, and then turn off the main unit 2 to prevent milk from spilling or being sucked back into the main unit 2; further, the "B" level signal represents a strong signal, indicating that the pressure sensor detects that the air pressure in the negative pressure chamber 260 has a large change in unit time, which is basically the same as the external air pressure, further indicating that the user has removed the flange 11 from the milk storage container part 50 without turning off the main unit 2 in advance. If the user attempts to perform further operations such as taking out milk, resulting in the opening of the milk storage container portion 50 being opened, the control unit 30 will automatically generate and issue a fourth prompt message to inform the user that the diaphragm 60 is not properly installed and the main unit 2 is not turned off, and will simultaneously shut down the main unit 2. Since the "B" level intensity of the third signal indicates that the diaphragm 60 has been removed from the milk storage container portion 50 along with the flange 11, the breast pump 1 needs to take automatic countermeasures in a timely manner. Therefore, the control unit 30 needs to directly shut down the main unit 2 while issuing the fourth prompt message to prevent milk from spilling or entering the main unit 2.

[0363] Exemplarily, the third signal is emitted by the third detection unit 133 disposed within the milk storage container portion 50. As a pressure sensor, the third detection unit 133 needs to detect the change in air pressure within the negative pressure chamber 260 over a fixed period of time to generate an accurate level signal. This prevents the flange 11 from being displaced by the user due to contact with the user, resulting in a prolonged misalignment of the flange 11 and a significant pressure change within the negative pressure chamber 260 due to prolonged air leakage. This pressure change from prolonged air leakage in the negative pressure chamber 260 is equivalent to the pressure change resulting from a user removing the diaphragm 60 from the milk storage container portion 50 along with the flange 11, thereby causing the control unit 30 to misjudge the signal level of the third signal. To this end, the control unit 30 detects the third signal at a predetermined time interval from the time the air pressure within the milk storage container portion 50 changes. This predetermined time interval can be 2 seconds, 3 seconds, or the like, and is not limited in this embodiment. The control unit 30 generates third signals of varying levels by measuring the pressure change within the predetermined time interval to ensure the accuracy of the third signal.

[0364] To ensure the accuracy of the fourth signal, the control unit also detects the fourth signal according to the time preset for the third signal in the previous embodiment, which will not be described in detail here.

[0365] Please refer to Figure 7. In the above embodiment, optionally, the negative pressure mechanism 20 in the main unit 2 is electrically connected to the control unit 30 so that the suction operation can be controlled by the control unit 30. It can be understood that when the third prompt message or the fourth prompt message appears and the main unit 2 is shut down at the same time, the negative pressure mechanism 20 is controlled by the control unit 30 to close, so that milk cannot enter the negative pressure mechanism 20 from the suction port of the negative pressure mechanism 20 and enter the machine chamber of the main unit 2 through the negative pressure mechanism 20; further, the breast pump 1 also includes a tee, one end of the tee is connected to the negative pressure mechanism 20, the other end is connected to the flange 11, and the last end is connected to the bowl body.

[0366] Below, based on the description of Figures 2-6 above, a detailed description of the method for detecting whether the breast pump is properly installed is provided in accordance with an embodiment of the present application. For example, please refer to Figures 7-8. Figure 8 is a flow chart of the method for detecting whether the breast pump is properly installed provided in accordance with an embodiment of the present application. This embodiment describes the method for detecting whether the flange is properly installed in accordance with an embodiment of the present application in detail, and the method is implemented by the control unit of the host. This embodiment includes:

[0367] The first step (S1): determining whether a first signal is detected, and when the first signal is detected, executing step S6; when the first signal is not detected, executing step S5;

[0368] Step 2: Determine whether the second signal is detected. If the second signal is detected, execute step S7; if the second signal is not detected, execute step S3.

[0369] Step 3: Determine whether the third signal is detected. If the third signal is detected, execute step S4; if the third signal is not detected, execute step S5.

[0370] Step 4: Detect the signal level of the third signal. When the signal level of the third signal is detected to be "A", execute step S8; when the signal level of the third signal is detected to be "B", execute step S9;

[0371] Step 5: The breast pump works normally;

[0372] Step 6: Automatically generate and issue a first prompt message to prompt the user to reassemble the flange and stop the milk pumping operation;

[0373] Step 7: Automatically generate and issue a second prompt message to prompt the user to reassemble the main unit and stop pumping;

[0374] Step 8: Automatically generate and issue a third prompt message to inform the user that the negative pressure chamber is leaking and the main unit is not turned off, stop the milk pumping operation, and then turn off the main unit;

[0375] Step 9: Automatically generate and issue a fourth prompt message to remind the user that the negative pressure chamber is leaking and the host is not turned off, and shut down the host at the same time.

[0376] FIG9 is a flow chart of a method for detecting a diaphragm not being properly installed provided by an embodiment of the present application. This embodiment describes the method for detecting whether the diaphragm is properly installed in detail, and implements the method through the control unit of the host. In FIG9 , this embodiment includes:

[0377] The first step (S1): determining whether the fourth signal is detected, and when the fourth signal is detected, executing step S3; when the fourth signal is not detected, executing step S2;

[0378] Step 2: The breast pump 1 works normally;

[0379] Step 3: Automatically generate and issue a fifth prompt message to prompt the user to reassemble the diaphragm and stop milk pumping.

[0380] Preferably, in the above solution, the first prompt information, the second prompt information, the third prompt information, and the fourth prompt information include prompting the user using voice broadcast, subtitle display, and vibration functions. When the breast pump's operations include milking tasks, massage tasks, cleaning tasks, etc., normal operation of the breast pump means continuing to perform the above functions. If the flange, main unit, and diaphragm are detected to be improperly installed, the control unit will control the air pump to stop milking without affecting the normal operation of other operations. This embodiment of the present application is not limited thereto.

[0381] In the second embodiment.

[0382] The breast milk volume detection method provided in the embodiments of the present application can be applied in the application environment shown in Figure 10. The milk storage container portion 50 is used to store breast milk, and a plurality of detection elements 40 for sensing breast milk can be provided on the milk storage container portion 50. Specifically, when breast milk reaches the position where any detection element 40 is provided, the detection element 40 can be triggered by sensing the breast milk. The detection device can execute the above-described breast milk volume detection method based on monitoring the triggering of the detection element 40, thereby achieving measurement of the breast milk volume in the milk storage container portion 50.

[0383] In an embodiment of the present application, as shown in Figures 10 and 12, a method for detecting the amount of breast milk is provided, comprising: obtaining detection parameters detected by a detection unit; and then performing a preset operation based on the detection parameters. This method is described using the breast milk flow detection unit 40 in Figure 10 as an example, and comprises the following steps:

[0384] Step 202: Acquire characteristic trigger information associated with the triggered condition of the detection element.

[0385] The association between the aforementioned characteristic triggering information and the triggered status of the detection elements 40 may be a direct association or an indirect association. A "direct association" means that the characteristic triggering information is directly related to the triggered status of the detection elements 40. For example, the characteristic triggering information includes, but is not limited to, at least one of the number of triggered detection elements 40 and the number of untriggered detection elements 40. In addition, an "indirect association" means that the triggered detection elements 40 have preset association information, and the characteristic triggering information is related to the preset association information. For example, the preset association information includes, but is not limited to, at least one of trigger channel information corresponding to each detection element 40, position information of each detection element 40 on the milk storage container portion 50, and capacity information corresponding to each detection element 40.

[0386] Step 204: Determine the current breast milk quantity information based on the feature trigger information and the preset relationship.

[0387] Among them, the preset relationship is used to characterize the mapping relationship and / or functional relationship between the feature trigger information and the breast milk amount information; "mapping relationship" refers to the one-to-one correspondence between the feature trigger information and the breast milk amount information, that is, there is a preset breast milk amount information corresponding to one feature trigger information; "functional relationship" refers to the preset functional relationship between the feature trigger information and the breast milk amount information, that is, by substituting the feature trigger information into the preset functional relationship, the breast milk amount information can be calculated.

[0388] The above-mentioned method for detecting the amount of breast milk obtains characteristic trigger information associated with the triggering of the detection element 40, and determines the current amount of breast milk based on the characteristic trigger information and a preset relationship, thereby determining the amount of breast milk in the milk storage container 50. Because the detection element 40 can be triggered during the process of breast milk extraction, the above-mentioned method can achieve real-time online detection of the amount of breast milk during the process of breast milk extraction. As shown in Figures 10, 12-13, in one embodiment, before step 202, the following is also included:

[0389] Step 302 , detecting the operating parameters of the breast milk in the milk storage container 50 by the detection element 40 ;

[0390] The detection element 40 includes but is not limited to a capacitive sensor or a photoelectric sensor, specifically, any one of a capacitive electrode, a photoelectric sensor, an infrared sensor, and a microwave detection sensor. Of course, other types of sensors are also feasible as long as they can detect the presence of breast milk when the breast milk reaches the setting position of the detection element 40 and are triggered to change their operating parameters. The operating parameters include any one of a capacitance value, a current value, and a voltage value.

[0391] In step 304, the operating parameters of each detection element 40 are compared with the trigger threshold to determine whether the operating parameters of each detection element 40 are greater than or equal to the preset trigger threshold. When the operating parameters of any detection element 40 are greater than or equal to the preset trigger threshold, it is determined that the detection element 40 is triggered; otherwise, it is determined that the detection element 40 is not triggered.

[0392] Among them, the setting of the trigger threshold is not limited, and it is specifically pre-set according to the operating parameters corresponding to when the detection element 40 senses breast milk. For example, in some embodiments, the trigger threshold can be the lowest value of the operating parameter corresponding to when the detection element 40 senses breast milk; of course, in other embodiments, the trigger threshold can be the rated value for normal operation when the detection element 40 is triggered.

[0393] For ease of understanding, the following description is made by taking the detection element 40 as a capacitor electrode as an example:

[0394] In the above steps, when the detection element 40 is a capacitor electrode, the operating parameter is the capacitance value of the detection element 40, and the preset trigger threshold is the preset capacitance threshold.

[0395] Specifically, when breast milk reaches the position where any capacitor electrode is set, the capacitor electrode will cause its own capacitance value to change due to the presence of breast milk. Therefore, after the capacitance value of the capacitor electrode is detected in real time through step 302, the capacitance value of each capacitor electrode is compared with the preset capacitance threshold in real time through step 304. The real-time triggering situation of each capacitor electrode can be determined based on the comparison result. Of course, it should be noted that the capacitor electrode can be a standardized capacitor electrode or a non-standardized capacitor electrode.

[0396] As shown in FIG10 and FIG12-14, based on the above steps 302-304, in order to improve the accuracy of detecting the triggering of the detection element 40, the following steps may be preferably set in step 304:

[0397] Step 402: When the operating parameter of any detection element 40 is greater than or equal to a preset trigger threshold, the stability of the operating parameter of the detection element 40 is detected;

[0398] Here, "stable condition" refers to the degree of stability of the operating parameters of the detection element 40. When the detection element 40 can stably sense breast milk, its operating parameters tend to be stable values ​​or values ​​that fluctuate within the allowable fluctuation range, and will not fluctuate or will not fluctuate beyond the allowable fluctuation threshold. At this time, the operating parameters of the detection element 40 are determined to be in a stable state; and when the operating parameters of the detection element 40 fluctuate beyond the allowable fluctuation threshold, the operating parameters of the detection element 40 are determined to be in an unstable state.

[0399] In step 402, taking time as an example of a factor for determining the stability of the operating parameters of the detection element 40, in some embodiments, step 402 specifically includes the following sub-steps:

[0400] (1) When the operating parameter of any detection element 40 is greater than or equal to the trigger threshold, the duration of the detection operating parameter being greater than or equal to the trigger threshold.

[0401] The “maintenance duration” refers to the duration during which the operating parameter of the detection element 40 is greater than the trigger threshold.

[0402] (2) When the duration is greater than the preset time, it is determined that the operating parameters of the detection element 40 are in a stable state.

[0403] Among them, the preset time is not limited and can be specifically set according to the actual application situation. For example, the preset time can be 3-10 seconds. In one embodiment, taking the preset time of 5 seconds as an example, when the operating parameters of any detection element 40 can be maintained greater than or equal to the trigger threshold for more than 5 seconds, and the maintenance time is 5 seconds, the operating parameters of the detection element 40 are in a stable state. On the contrary, if the maintenance time is less than or equal to 5 seconds, the operating parameters of the detection element 40 are in an unstable state.

[0404] Step 404 : When the operating parameters of the detection element 40 are in a stable state, it is determined that the detection element 40 is in a triggered state.

[0405] It should be noted that the milk storage container portion 50 has N capacity positions. The capacity positions are virtual positions defined on the milk storage container portion 50 according to the positions corresponding to different capacities. There is no need to set scale lines on the milk storage container portion 50. The capacities corresponding to the first to the Nth capacity positions increase in sequence. At least one detection element 40 is provided at each capacity position.

[0406] The capacity of the milk storage container portion 50 is unlimited. For example, in some embodiments, taking the capacity of the milk storage container portion 50 as 150 ml, if the capacity of the milk storage container portion 50 is divided into 15 equal parts, the milk storage container portion 50 has 15 capacity positions. Specifically, the first capacity position corresponds to the position corresponding to the capacity of the milk storage container portion 50 of 10 ml, the second capacity position corresponds to the position corresponding to 20 ml, ..., and so on, the 15th capacity position corresponds to the position corresponding to 150 ml.

[0407] It's worth noting that each capacity position is defined as a virtual spatial position on the milk storage container portion corresponding to a capacity level. Physical capacity scale lines can be used on the milk storage container portion to assist in indicating the capacity position, or the capacity position corresponding to a capacity level can be determined based on the liquid levels of liquids of different capacity levels injected into the milk storage container portion. For example, in an embodiment of a milk storage container portion with capacity scale lines, the capacity scale lines have multiple scale marks corresponding to different capacity levels, and the position of each scale mark can be considered a capacity position. In an embodiment of a milk storage container portion without capacity scale lines, when a certain volume of liquid is injected, the liquid level position displayed on the milk storage container portion can be considered a capacity position. For example, if 10 ml of liquid is injected into the milk storage container portion, the liquid level position of 10 ml of liquid on the milk storage container portion can be considered to correspond to the 10 ml capacity level.

[0408] It should be noted that the above embodiment is described based on the milk storage container portion of FIG10 . The capacity positions of the milk storage container portion in FIG10 are evenly spaced in the extension direction of the milk storage container portion. Of course, the capacity positions of the milk storage container portion may also be arranged at non-equal intervals. For example, the capacity positions of the milk storage container portion 50 a shown in FIG11 are arranged at non-equal intervals. Therefore, the plurality of detection elements 40 a are arranged at non-equal intervals in the milk storage container portion 50 a.

[0409] As shown in FIG. 10 , 12 , and 15 , based on the above-mentioned setting of the capacity position, in one embodiment, the above-mentioned step 202 specifically includes:

[0410] Step 502 : When the detection element 40 at the i-th capacity position is triggered, the highest capacity position is determined from the i-th capacity positions, where i is a natural number and 1≤i≤N.

[0411] Specifically, the milk storage container portion 50 has a capacity of 150 ml and 15 capacity positions. Assuming that all detection elements 40 on the milk storage container portion 50 are intact, if the milk storage container portion 50 contains 100 ml of breast milk, the detection elements 40 at the 1st to 10th capacity positions will be triggered. In this case, i=10. Then, the one with the highest capacity value among the 10 capacity positions can be selected as the highest capacity position. For example, if the capacity value corresponding to the 10th capacity position is the highest, the 10th capacity position corresponding to the capacity of 100 ml is determined to be the highest capacity position.

[0412] Step 504 : Acquire characteristic triggering information for indicating that the detection element 40 at the highest capacity position is triggered.

[0413] Specifically, for example, when taking the 10th capacity position as the highest capacity position, the characteristic trigger information of the detection element 40 being triggered at the 10th capacity position is obtained. The characteristic trigger information is associated with the capacity 100 ml corresponding to the 10th capacity position where the detection element 40 is located.

[0414] The above step 204 specifically includes:

[0415] Step 506: According to the feature trigger information and the preset mapping relationship between the feature trigger information and the breast milk amount information, it is determined that the capacity corresponding to the highest capacity position matches the current breast milk amount information.

[0416] Specifically, for example, when the detection element 40 representing the 10th capacity position with the characteristic trigger information is triggered, based on the 10th capacity position corresponding to the detection element 40 and the mapping relationship between the preset characteristic trigger information and the breast milk amount information, it is determined that the capacity 100 ml corresponding to the 10th capacity position matches the current breast milk amount information, that is, the detection result is that the current breast milk amount of the milk storage container portion 50 is 100 ml.

[0417] It should be noted that, in addition to the case where all the detection elements 40 on the milk storage container portion 50 are intact, the above steps 502-506 also apply when some of the detection elements 40 on the milk storage container portion 50 are damaged. For example, if the detection element 40 at the 10th capacity position is damaged and cannot be triggered, in step 502, when the milk storage container portion 50 contains 110 ml of breast milk, the detection elements 40 at the 1st to 9th capacity positions and the detection element 40 at the 11th capacity position are triggered, for a total of 10 capacity positions. Among these 10 capacity positions, the capacity value corresponding to the 11th capacity position is the highest, and the 11th capacity position corresponding to the capacity of 110 ml is determined to be the highest capacity position. In the subsequent steps 504-506, calculations are performed based on the detection element 40 at the 11th capacity position being triggered, and the final detection result is that the current breast milk amount in the milk storage container portion 50 is 110 ml. As shown in Figures 10, 3, and 7, in another embodiment, step 202 includes:

[0418] Step 602 , when the detection element 40 at the i-th capacity position is detected to be triggered, characteristic triggering information indicating that the detection element 40 at the i-th capacity position is triggered is obtained, where i is a natural number and 1≤i≤N;

[0419] Specifically, the milk storage container 50 has a capacity of 150 ml and 15 capacity positions. Assuming that all detection elements 40 on the milk storage container 50 are intact, if the milk storage container 50 contains 100 ml of breast milk, the detection elements 40 at the 1st to 10th capacity positions will be triggered. In this case, i=10, and characteristic triggering information indicating that the detection element 40 at the 10th capacity position is triggered is obtained. This characteristic triggering information is associated with the capacity of 100 ml corresponding to the 10th capacity position where the detection element 40 is located.

[0420] Step 204 includes:

[0421] Step 604: According to the feature trigger information and the preset mapping relationship between the feature trigger information and the breast milk amount information, it is determined that the capacity corresponding to the i-th capacity position matches the current breast milk amount information.

[0422] Specifically, for example, when the detection element 40 representing the 10th capacity position with the characteristic trigger information is triggered, based on the 10th capacity position corresponding to the detection element 40 and the mapping relationship between the preset characteristic trigger information and the breast milk amount information, it is determined that the capacity 100 ml corresponding to the 10th capacity position matches the current breast milk amount information, that is, the detection result is that the current breast milk amount of the milk storage container portion 50 is 100 ml.

[0423] As shown in Figures 10, 12, and 17, in another embodiment, only one detection element is provided at each capacity position; in this case, step 202 includes:

[0424] In step 702 , the number of the triggered detection elements 40 is detected as i, where i is a natural number and 1≤i≤N.

[0425] Specifically, when the milk storage container portion 50 contains 130 ml of breast milk, the detection elements 40 at the 1st to 13th capacity positions will be triggered, that is, the number of the triggered detection elements 40 is 13. At this time, i=13.

[0426] Step 704 : Acquire characteristic trigger information for characterizing that the number i of the triggered detection elements 40 is i.

[0427] Specifically, taking the milk storage container portion 50 containing 130 ml of breast milk as an example, characteristic trigger information indicating that the number of triggered detection elements 40 is i=13 is obtained.

[0428] Step 204 includes:

[0429] Step 706 , performing calculations based on the characteristic trigger information and the functional relationship between the characteristic trigger information and the breast milk quantity information, to obtain the current breast milk quantity information that matches the capacity corresponding to when the i detection elements 40 are triggered.

[0430] Specifically, taking the example of characteristic trigger information indicating that the number of triggered detection elements 40 is i=13, calculation is performed based on the function Q=i×a, where Q is the volume corresponding to when i detection elements 40 are triggered, i is the number of triggered detection elements 40, and a is the volume interval between two adjacent volume positions. Here, taking the milk storage container 50 as an example, with a capacity of 150ml and 15 volume positions, and a=10ml, then Q=13×10ml=130ml, to obtain the current breast milk volume information corresponding to the 130ml volume corresponding to when 13 detection elements 40 are triggered. That is, the detection result indicates that the current breast milk volume in the milk storage container 50 is 130ml. It is worth noting that there is no limitation on the method for triggering the detection elements. In addition to the aforementioned embodiment of automatically monitoring the operating parameters of the detection elements to determine whether they have been triggered, in other embodiments, the detection elements can also be triggered manually.

[0431] In some embodiments, the above method further comprises:

[0432] Display the current breast milk quantity information, and / or output the current breast milk quantity information to an external terminal device.

[0433] Specifically, there are no restrictions on the way in which breast milk quantity information is fed back to the user, including but not limited to the following two ways:

[0434] (1) The breast milk flow detection unit using the above method, in addition to calculating the breast milk amount information, can also directly display the breast milk amount information through the display module provided thereon for the convenience of the user;

[0435] (2) The breast milk flow detection unit can also output the current breast milk amount information to an external terminal device. The terminal device can be set up with an application APP, and the user can display the breast milk amount information on the UI interface of the corresponding application APP.

[0436] It should be understood that, although the various steps in the flowcharts involved in the various embodiments described above are displayed in sequence according to the instructions of the arrows, these steps are not necessarily executed in sequence in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders. Moreover, at least a portion of the steps in the flowcharts involved in the various embodiments described above can include multiple steps or multiple stages, and these steps or stages are not necessarily executed and completed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a portion of steps or stages in other steps.

The solution provided by this device is similar to the solution described in the aforementioned method. Therefore, the specific limitations of one or more breast milk flow detection unit embodiments provided below can be found in the above-described limitations of the breast milk volume detection method and will not be further elaborated here.

[0441] In one embodiment, the data calculation module is further used to detect the operating parameters of any detection element 40 when it senses breast milk in the milk storage container; when the operating parameter of any detection element 40 is greater than a preset trigger threshold, it is determined that the detection element 40 is triggered.

[0450] Each module in the above-mentioned breast milk flow detection unit can be implemented in whole or in part through software, hardware, or a combination thereof. Each of the above-mentioned modules can be embedded in or independent of the processor of the computer device in hardware form, or can be stored in the memory of the computer device in software form, so that the processor can call and execute the corresponding operations of each of the above modules.

[0451] In one embodiment, as shown in FIG. 19-20 , a breast pump 900 is provided, comprising:

[0452] A breast milk collecting portion 10 for extracting breast milk from a user's breast;

[0453] a milk storage container portion 50 , connected to the breast milk collection portion, for storing breast milk;

[0454] The above-mentioned detection device is used to detect the amount of breast milk stored in the milk storage container portion 50;

[0455] The control unit 30 is electrically connected to the breast milk collecting portion 10 and the detection device. The control unit 30 is used to control the breast milk collecting portion 10 to squeeze the user's breast to secrete breast milk. The control unit 30 is also used to control the detection device to detect the amount of breast milk flowing into the milk storage container portion 50.

[0456] Specifically, the breast milk collecting portion 10 further includes a breast shield (not shown) and a negative pressure mechanism (not shown); wherein the breast shield is used to accommodate a woman's breast for breast pumping, and the negative pressure mechanism is used to generate negative pressure under the control of the control unit to squeeze the user's breast to make the breast secrete breast milk and then extract the breast milk.

[0457] It is worth mentioning that, in some embodiments, the control unit 30 and the data operation module 270 of the detection device can be integrated into the same circuit board (ie, main board); of course, in other embodiments, the two can also be located on different circuits.

[0458] In the third embodiment.

[0459] As shown in FIG21 , the present invention provides a method for detecting the amount of breast milk, which is applied to a breast pump, and includes: obtaining detection parameters obtained by a detection unit; and executing a preset operation according to the detection parameters.

[0460] In this embodiment, obtaining the detection parameter detected by the detection unit includes: receiving breast milk extracted by a breast pump in a single session, measuring the amount of breast milk extracted by the breast pump in at least a single session, and obtaining the detection parameter of the breast milk amount.

[0461] In this embodiment, the breast pump utilizes negative pressure generated by a negative pressure mechanism to extract breast milk. The negative pressure mechanism operates by alternating cycles of suction, release, suction, and release. A single extraction is defined as the breast milk obtained by the breast pump's negative pressure mechanism during a single extraction. This single extraction provides a real-time reflection of the milk production status of the user's breast in the breast pump's current operating mode. In specific embodiments of the present invention, the breast pump can accept breast milk extracted from a single extraction, as well as from two or three extractions.

[0462] In a specific embodiment of the present invention, single-time expressed breast milk refers to breast milk obtained by a single suction by the negative pressure mechanism of the breast pump, that is, the single-time expressed breast milk is obtained between two adjacent suction operations of the negative pressure mechanism of the breast pump. It can also be understood that the breast milk extracted by the single-time expressed breast milk is received between two adjacent suction operations of the negative pressure mechanism of the breast pump, and the receiving time is controlled between the two adjacent suction operations of the negative pressure mechanism.

[0463] In this embodiment, the amount of breast milk extracted by a breast pump in at least a single session is measured. Specifically, the volume, weight, or other parameters of the breast milk extracted in a single session are measured using a detection element such as a capacitive sensor, a resistive sensor, or a photoelectric sensor. Specifically, the amount of breast milk extracted in a single session is the single breast milk volume, and the information about the single breast milk volume includes the single breast milk volume value, the relationship between the single breast milk volume value and time, or scattered information about the single breast milk volume value.

[0464] In a specific embodiment of the present invention, after the measurement of the amount of breast milk extracted in a single time is completed, the breast milk extracted in a single time is released so that the breast milk is collected in the milk storage container. After each measurement is completed, the breast milk is released to facilitate the next measurement.

[0465] As shown in FIG22 , the present invention measures the amount of breast milk extracted by a breast pump at least once and then calculates the sum of the amounts of breast milk extracted at least once to obtain the current amount of breast milk extracted by the breast pump (total amount). Specifically, the amount of breast milk extracted by each individual extraction is first measured; then, the current amount of breast milk extracted by the breast pump (total amount) is determined based on the sum of the amounts of breast milk extracted at each individual extraction.

[0466] The detection of the amount of breast milk in the embodiment of the present invention is based on the measurement of breast milk extracted in a single session, specifically the amount of breast milk extracted in a single session. Therefore, the value of the total amount of breast milk obtained is very accurate with little error.

[0467] As shown in FIG23 , a method for controlling a breast pump according to an embodiment of the present invention includes:

[0468] Measuring the amount of breast milk extracted by a breast pump in a single session. In a specific embodiment of the present invention, measuring the amount of breast milk extracted by a breast pump in a single session, specifically, measuring the amount of breast milk obtained by a single suction by the negative pressure mechanism of the breast pump. The amount of breast milk extracted in a single session is the single breast milk volume.

[0469] Control the processing task of the breast pump according to at least a single amount of breast milk (the amount of breast milk extracted in a single time) within a preset time.

[0470] The information about at least a single breast milk amount includes a single breast milk amount, information about the relationship between a single breast milk amount and time, and scattered information about a single breast milk amount. The preset time refers to a single breast milk amount, information about the relationship between a single breast milk amount and time, and scattered information about a single breast milk amount within a fixed time period, such as scattered time within one day, two days, three days, or a fixed time period.

[0471] In the embodiment of the present invention, the processing tasks of the breast pump include adjusting the working parameters of the negative pressure mechanism of the breast pump and adjusting the working mode of the breast pump.

[0472] The intelligent control method for a breast pump according to an embodiment of the present invention intelligently controls the operation of the breast pump based on the amount of breast milk extracted in a single session (single breast milk volume). Since single breast milk extracted is milk obtained through a single suction by a negative pressure mechanism, the single breast milk volume information can instantly reflect the milk production status of the user's breasts in the breast pump's current operating mode. The single breast milk volume information includes the single breast milk volume value, the relationship between the single breast milk volume value and time, and the scatter plot information of the single breast milk volume value (herein, the single breast milk volume refers to the breast milk volume of a single extraction). For example, a large single extraction value indicates that the user's current physical condition is compatible with the current task of the breast pump. For example, a small single extraction volume indicates that the user's current physical condition is not compatible with the current task of the breast pump. The breast pump can then intelligently adjust the operating parameters of its negative pressure mechanism or the operating mode of the breast pump to ensure that the user can normally express breast milk under the adapted task.

[0473] The relationship between the amount of breast milk delivered per session and time provides feedback on the vacuum mechanism's performance during a specific time period. Based on this information, adjustments can be made to the mechanism's operating parameters, such as the duration of a single pumping session, the negative pressure or vacuum level, the peak negative pressure or vacuum level, and the pump cycle time or frequency. If the amount of breast milk delivered per session is consistently high during a specific time period, the vacuum mechanism can be adjusted to increase the negative pressure or vacuum level to shorten the duration of a single pumping session, or to increase the pump cycle frequency to shorten the pump cycle time.

[0474] The scattered information of the single breast milk volume value can feedback the working status of the negative pressure mechanism when the user uses the breast pump at the scattered time, and can feedback the mother's milk production situation at the scattered time, and then intelligently remind the user of the best time to use the breast pump. For example, based on the size relationship between the user's single breast milk volume values ​​at 8 o'clock, 9 o'clock and 10 o'clock in the morning, the user is intelligently reminded that the best time to use the breast pump is the best breast pumping time line in the morning; or, based on the historical single breast milk volume at 8 o'clock in the morning, the user's breast pumping situation at 8 o'clock in the morning is fed back, that is, a large single breast milk volume indicates that the user's current processing effect of using the breast pump is good. If the current single breast milk volume at 8 o'clock in the morning is smaller than the historical single breast milk volume at 8 o'clock in the morning, it means that the user's current processing effect of using the breast pump is not good, and it is necessary to adjust the processing task of the breast pump, that is, adjust the working mode of the breast pump.

[0475] The present invention controls the processing tasks of a breast pump based on the amount of breast milk extracted from a single session, thereby improving the application of this information and enhancing the intelligent application of the breast pump. Because the amount of breast milk extracted from a single session can promptly and in real time reflect the user's current status, the intelligent control method of the breast pump of the present invention is more intelligent, advanced, timely, and effective, thereby enhancing the user experience. In other embodiments of the present invention, the processing tasks of the breast pump can also be adjusted based on the amount of breast milk extracted from two or three sessions.

[0476] In certain embodiments of the present invention, the operating frequency of the negative pressure mechanism of the breast pump is adjusted based on the relationship between a single breast milk volume value and a preset breast milk volume threshold, wherein the preset breast milk volume threshold can be a single breast milk volume threshold or multiple breast milk volume thresholds. Based on actual applications, multiple breast milk volume thresholds are set to match different gears of the breast pump processing tasks.

[0477] In an embodiment of the present invention, the preset breast milk volume threshold includes a first breast milk volume threshold and a second breast milk volume threshold, and the settings of the two can be set according to the average single milk volume of the mother. For the sake of convenience, in the present invention, the first breast milk volume threshold is greater than the average single milk volume of the mother, and the second breast milk volume threshold is less than the average single milk volume of the mother.

[0478] The average single milk output of the mother can also be obtained by measuring multiple values ​​using the method for detecting the amount of sucked breast milk according to an embodiment of the present invention and calculating the average value of the multiple measured values.

[0479] The average single milk output of the mother can also be estimated in advance based on the average daily breast milk secretion of the mother, the number of feedings per day, and the number of suctions per breast pump, and is preset in advance by the control unit of the breast pump. For example, if the average daily breast milk secretion of a normal mother is 600-1500 mL, the normal number of feedings per day is 4-6, and the number of suctions per breast pump (the number of adjacent suction operations of the negative pressure mechanism 20) is 100-150 times, the estimated average single milk output of the mother is 0.7-3.75 mL. For example, the second breast milk volume threshold is set to 2 mL, and the first breast milk volume threshold is set to 4 mL.

[0480] According to the relationship between the single breast milk volume and the preset breast milk volume threshold, adjust the working frequency of the breast pump's negative pressure mechanism. The specific operations are as follows:

[0481] When the single breast milk volume exceeds the first breast milk volume threshold, it indicates that the breast is producing milk well (e.g., a gusher), indicating that milk flow is good. Increasing the pump cycle frequency can quickly complete the milking process and shorten the working time of the breast pump.

[0482] When it is determined that the single breast milk amount value is between the second breast milk amount threshold and the first breast milk amount threshold, the current operating frequency of the negative pressure mechanism of the breast pump is maintained.

[0483] In certain embodiments of the present invention, the processing task of controlling the breast pump based on the information of the amount of breast milk extracted in a single session further includes:

[0484] Adjusting the working mode of the breast pump according to the relationship between the single breast milk volume value and the preset breast milk volume threshold, wherein the working mode of the breast pump includes a milking mode and a lactation mode;

[0485] The specific operations are as follows:

[0486] When it is determined that the single breast milk amount is lower than the second breast milk amount threshold, the milking mode of the breast pump is adjusted to the lactation induction mode, and the lactation induction mode is started.

[0487] In addition, in certain embodiments of the present invention, the preset breast milk volume threshold is set to only one value, namely, the third breast milk volume threshold, and the third breast milk volume threshold is close to the average single milk output of the mother.

[0488] If the amount of breast milk produced in a single delivery is determined to be lower than the third breast milk volume threshold, the breast pump's milking mode is switched to the lactation stimulation mode, and the lactation stimulation mode is activated. If the amount of breast milk produced in a single delivery is determined to be higher than the third breast milk volume threshold, the lactation stimulation mode is stopped, the device is switched to the milking mode, and the power of the air pressure pump is adjusted so that the current power of the air negative pressure mechanism is suitable for milk production in the user's breasts.

[0489] The present invention can preset multiple breast milk volume thresholds, and intelligently adjust the operating mode of the breast pump based on the comparison of a single breast milk volume with the multiple values. In an embodiment of the present invention, the lactation induction mode includes one or more of the following methods: breast massage, breast electrical stimulation, and breast thermal stimulation.

[0490] As shown in FIG24 , a breast pump 1 according to an embodiment of the present invention includes:

[0491] The host 2 includes a negative pressure mechanism 20 for generating negative pressure and a control unit 30. The negative pressure mechanism 20 works by sucking once, releasing pressure once, sucking once, releasing pressure once, and sucking and releasing pressure alternately in a cycle. The control unit 30 is a technology well known to those skilled in the art and will not be described in detail in the present invention.

[0492] The breast milk collecting portion 20 is used to contact the user's breast and absorb breast milk under the negative pressure of the negative pressure mechanism 20.

[0493] The measuring container is used to receive breast milk extracted from the breast milk collection unit 20. In this embodiment of the present invention, the measuring container receives a single amount of breast milk extracted from the breast milk collection unit 20 each time, and after the measurement is completed, releases the single amount of breast milk, receives the next single amount of breast milk, measures it again, and then releases it again.

[0494] The detection unit 40 is used to detect the single amount of breast milk received in the measuring container from the breast milk collecting part 20 in a single extraction.

[0495] The milk storage container portion 50 is detachably connected to the breast milk collecting portion 20 and is used to hold breast milk released from the measuring container. The milk storage container portion 50 can be made of a hard or soft material, and the shape of the container can be fixed or amorphous. For example, in this embodiment of the present invention, the shape of the container is bowl-shaped.

[0496] The control unit 30 is electrically connected to the detection unit 40 and is configured to receive information about a single breast milk delivery and control processing tasks of the breast pump. In this embodiment, the information about a single breast milk delivery includes a single breast milk delivery value, information about the relationship between the single breast milk delivery value and time, and scattered information about the single breast milk delivery value.

[0503] The breast shield 21 is designed to fit the user's breast. The expressed breast milk flows along the nipple channel to the diaphragm 60 and into the measuring container 800. In the embodiment of the present invention, the measuring container is a conduit 281. That is, the present invention utilizes the conduit 281 to receive a single amount of breast milk extracted from the breast milk collection portion 20. After the measurement is completed, the one-way valve releases the single amount of breast milk and receives the next single amount of breast milk, which is then measured and released again.

[0504] In the embodiment of the present invention, the conduit 281 is fixed to the inner wall of the milk storage container 50 via a bracket. Of course, the conduit 281 can also be directly provided on the inner wall of the milk storage container 50 .

[0505] As shown in FIG26 , in the breast pump of the embodiment of the present invention, the detection unit 40 is electrically connected to the control unit to feed back information on the amount of breast milk delivered in a single feeding to the control unit. The detection unit 40 includes a capacitive sensor, a resistive sensor, or a photoelectric sensor.

[0516] Through the input unit, the user can directly input user parameters through the breast pump and adjust the working parameters of the breast pump so that the working parameters of the breast pump are more in line with their own needs.

[0517] In some embodiments, the housing also includes a display unit 101 electrically connected to the control unit 20, and the display unit 101 includes at least one of a first display area 106 and a second display area 107, wherein the first display area 106 is used to display the user parameters, and the second display area 107 is used to display the working parameters.

[0518] In some embodiments, the display unit 101 exists independently of the input unit. In this case, please refer to Figure 28, which is a second structural diagram of a breast pump provided by the present application. As shown in Figure 28, the breast pump in Figure 28 has both the input unit 102 and the display unit 101.

[0519] In some embodiments, the display unit 101 and the input unit 102 are the same panel, and the display unit 101 and the input unit 102 are defined to together constitute an operation panel. At this time, the user can input user parameters through the operation panel, and can also view the first display area and / or the second display area through the operation panel.

[0520] In some embodiments, the breast pump further comprises a communication unit electrically connected to the control unit, wherein the communication unit is configured to establish communication with an external terminal, and the control unit is connected to the communication unit.

[0521] In some embodiments, the breast pump comprises both a communication unit and an input unit.

[0522] By setting a communication unit on the breast pump to communicate with an external terminal, users can set their own user parameters through a mobile phone APP, etc., thereby improving the convenience of using the breast pump.

[0523] In some embodiments, the user parameters include at least one of age, breast size, and compression capacity.

[0524] In some embodiments, the working parameter includes at least one of a lactation parameter and a milk suction parameter.

[0525] In some embodiments, the lactation induction parameters include at least one of the lactation induction frequency, the lactation induction intensity, and the lactation induction time.

[0526] Among them, increasing any one of the frequency, intensity and duration of lactation can help mothers secrete more breast milk, thereby increasing the amount of breast milk sucked out during subsequent breast pumping.

[0527] Please refer to FIG29 , which is a schematic diagram of the structure of a terminal provided by an embodiment of the present application. As shown in FIG29 , the terminal 103 includes a control interface 104 .

[0528] In some embodiments, the control interface 104 includes an input control 105 for inputting the user parameters.

[0529] In some implementations, when the user parameter includes multiple sub-parameters, the control interface includes multiple input controls 105 .

[0530] For example, when the user parameters include age, breast size, and pressure-bearing capacity, the control interface includes three input controls 105 , and the three input controls 105 are used to input age, breast size, and pressure-bearing capacity, respectively.

[0531] In some embodiments, the control interface 104 further includes a third display area, which is used to display the current operating parameters of the breast pump.

[0532] In some embodiments, the control interface 104 further includes a fourth display area, and the fourth display area is used to display the working parameters corresponding to the user parameters after the user inputs the user parameters.

[0533] Please refer to Figure 30, which is a flow chart of a control method provided by an embodiment of the present application. As shown in Figure 30, the breast pump operation control method includes: first step to third step.

[0534] The first step: obtaining user parameters; wherein the user parameters include pressure bearing capacity.

[0535] In some embodiments, the first step includes the following steps.

[0536] (1) Acquiring the user parameter generated by the input unit of the breast pump in response to the user's input instruction.

[0537] (2) Alternatively, the user parameters sent by the external terminal are obtained.

[0538] Step 2: determining working parameters of the breast pump according to the user parameters; wherein the working parameters include milk suction parameters, and the milk suction parameters include milk suction intensity and milk suction time, the milk suction intensity is positively correlated with the pressure bearing capacity, and the milk suction time is negatively correlated with the pressure bearing capacity.

[0539] In some embodiments, the user parameters include at least one of age, breast size, and compression capacity.

[0540] In some embodiments, the working parameter includes at least one of a lactation parameter and a milk suction parameter.

[0541] In some embodiments, the lactation induction parameters include at least one of the lactation induction frequency, the lactation induction intensity, and the lactation induction time.

[0542] Among them, increasing any one of the frequency, intensity and duration of lactation can help mothers secrete more breast milk, thereby increasing the amount of breast milk sucked out during subsequent breast pumping.

[0543] In some embodiments, the milk pumping parameter includes at least one of milk pumping frequency, milk pumping intensity, and milk pumping time.

[0544] Among them, increasing any one of the pumping frequency, pumping intensity and pumping time can allow the breast pump to suck out more breast milk when the breast pump finishes pumping.

[0545] In some embodiments, the breast pump has reference operating parameters. If the breast pump does not obtain the user parameters, ie, the user does not input the user parameters, the breast pump operates according to the reference operating parameters.

[0546] Furthermore, the baseline operating parameters include at least one of a default lactation induction parameter and a default milk extraction parameter.

[0547] For example, when the working parameter is a lactation parameter, older women usually secrete less breast milk. In order to ensure that a sufficient amount of breast milk is sucked out, after comparing the default lactation parameters, if the woman is older, at least one of the lactation frequency, lactation intensity and lactation time is increased to increase the amount of breast milk sucked out in subsequent milk pumping work.

[0548] Furthermore, after comparing the default lactation parameters, if the age is young, at least one of the lactation frequency, lactation intensity and lactation time is reduced to prevent excessive breast milk from being sucked out during subsequent breastfeeding, which is not conducive to the mother's subsequent weaning.

[0549] For example, when the working parameter is breast size, smaller breasts generally secrete less breast milk. In order to ensure that a sufficient amount of breast milk is sucked out, after comparing the default lactation parameters, if the breast size is smaller, at least one of the lactation frequency, lactation intensity, and lactation time is increased to increase the amount of breast milk sucked out in subsequent milk sucking operations.

[0550] Furthermore, after comparing the default lactation parameters, if the breast size is large, at least one of the lactation frequency, lactation intensity, and lactation time is reduced to prevent excessive breast milk from being sucked out during subsequent breast pumping, which is not conducive to the mother's subsequent weaning.

[0551] For example, a user with a strong pressure-bearing capacity can withstand greater lactation pressure. At this time, compared with the default lactation parameters, if the pressure-bearing capacity increases, at least one of the lactation frequency and lactation intensity will be increased, while the lactation time will be reduced to complete the lactation work faster and save time for users with a strong pressure-bearing capacity in using a breast pump.

[0552] Furthermore, after comparing the default lactation parameters, if the pressure-bearing capacity is small, at least one of the lactation frequency and intensity is reduced, and the lactation time is increased, so as to complete the lactation work with more soothing pressure and prevent the user from feeling pain during the use of the breast pump.

[0553] For example, when the working parameters are breast pumping parameters, older people usually secrete less breast milk. In order to ensure that a sufficient amount of breast milk is sucked out, after comparing the default user parameters, if the age is older, at least one of the breast pumping frequency, breast pumping intensity and breast pumping time is increased to increase the amount of breast milk sucked out in subsequent breast pumping work.

[0554] Furthermore, after comparing the default user parameters, if the age is young, at least one of the pumping frequency, pumping intensity and pumping time is reduced to prevent excessive breast milk from being sucked out during the pumping process, which is not conducive to the mother's subsequent weaning.

[0555] For example, when the working parameter is breast size, smaller breasts generally secrete less breast milk. To ensure that a sufficient amount of breast milk is expressed, after comparing the default user parameters, if the breast size is smaller, at least one of the pumping frequency, pumping intensity, and pumping time is increased to increase the amount of breast milk expressed during the pumping operation.

[0556] Furthermore, after comparing the default user parameters, if the breast size is large, at least one of the pumping frequency, pumping intensity, and pumping time is reduced to prevent excessive breast milk from being sucked out during subsequent pumping, which is not conducive to the mother's subsequent weaning.

[0557] For example, a user with a strong pressure-bearing capacity can withstand greater suction pressure. At this time, compared with the default suction parameters, if the pressure-bearing capacity is greater, at least one of the suction frequency and the suction intensity will be increased, while the suction time will be reduced to complete the suction work faster, saving time for users with strong pressure-bearing capacity in using the breast pump.

[0558] Furthermore, after comparing with the default user parameters, if the pressure bearing capacity is small, at least one of the pumping frequency and the pumping intensity is reduced, and the pumping time is increased, so as to complete the pumping work with more soothing pressure and prevent the user from feeling pain during the use of the breast pump.

[0559] In some implementations, the user parameters do not need to be compared with the default user parameters. After the user parameters are obtained, the corresponding operating parameters can be searched in a pre-stored table of correspondence between user parameters and operating parameters according to the user parameters.

[0560] For example, after the pressure-bearing capacity is obtained, the corresponding milking intensity and milking time are obtained by looking up the table of correspondences between the pressure-bearing capacity, the milking intensity, and the milking time according to the pressure-bearing capacity.

[0561] In some implementations, the pre-stored table of correspondence between user parameters and working parameters is obtained based on correlation and testing between the user parameters and working parameters in the table.

[0562] In some embodiments, the milk pumping parameters further include milk pumping frequency, and determining the operating parameters of the breast pump according to the user parameters includes:

[0563] The milking frequency of the breast pump when in operation is determined according to the pressure bearing capacity; wherein the pressure bearing capacity is positively correlated with the milking frequency.

[0564] In some embodiments, the milking frequency is determined by looking up the table of correspondence between pressure-bearing capacity and milking frequency according to the pressure-bearing capacity.

[0565] In some embodiments, the pressure bearing capacity is compared with the default pressure bearing capacity in the default user parameters, and the final milk pumping frequency is adjusted based on the default milk pumping frequency according to the comparison result.

[0566] In some embodiments, the operating parameters further include lactation parameters, and determining the operating parameters of the breast pump according to the user parameters includes:

[0567] The working parameters of the breast pump are determined according to the lactation induction parameters.

[0568] In some embodiments, the lactation induction parameters include lactation induction time and lactation induction frequency, and determining the working parameters of the breast pump according to the lactation induction parameters includes:

[0569] The lactation induction time and frequency of the breast pump when working are determined according to the pressure bearing capacity; wherein the lactation induction intensity is positively correlated with the pressure bearing capacity, and the lactation induction time is negatively correlated with the pressure bearing capacity.

[0570] In some embodiments, the second step includes the following steps.

[0571] (1) Obtain baseline operating parameters.

[0572] (2) Determine the deviation working parameters according to the user parameters.

[0573] (3) Determining the operating parameters of the breast pump according to the baseline operating parameters and the deviation operating parameters.

[0574] In some embodiments, the deviation operating parameter is a coefficient, and the baseline operating parameter*the deviation operating parameter=the operating parameter of the breast pump during operation.

[0575] In some implementations, user parameters corresponding to age are divided into ranges, and different age ranges correspond to different operating parameters, ie, coefficients.

[0576] As an example, the user parameters are defined to include age, the working parameters include lactation intensity, the age ranges are divided into 18-25 years old, 25-35 years old, and over 35 years old, and the age range corresponding to the baseline working parameters of the breast pump is 25-35 years old. If the age range of the user parameter is 18-25 years old, the deviation working parameter is determined to be 0.9. At this time, the lactation intensity of the breast pump when working is the baseline lactation intensity corresponding to the baseline working parameter * 0.9; if the age range of the user parameter is over 35 years old, the deviation working parameter is determined to be 1.1. At this time, the lactation intensity of the breast pump when working is the baseline lactation intensity corresponding to the baseline working parameter * 1.1.

[0577] In some embodiments, the deviation operating parameter is a deviation value, and the baseline operating parameter+the deviation value=the operating parameter of the breast pump during operation.

[0578] As an example, the user parameters are defined to include age, the working parameters include lactation intensity, the age ranges are divided into 18-25 years old, 25-35 years old, and over 35 years old, and the age range corresponding to the baseline working parameters of the breast pump is 25-35 years old. If the age range of the user parameter is 18-25 years old, the deviation working parameter is determined to be -0.005MPa. At this time, the lactation intensity of the breast pump when working is the baseline lactation intensity corresponding to the baseline working parameter + (-0.005MPa); if the age range of the user parameter is over 35 years old, the deviation working parameter is determined to be +0.005MPa. At this time, the lactation intensity of the breast pump when working is the baseline lactation intensity corresponding to the baseline working parameter + (+0.005MPa).

[0579] In some embodiments, the operating parameters corresponding to the pressure bearing capacity are divided into levels, and different levels correspond to different coefficients or deviation values.

[0580] In some embodiments, the working parameters corresponding to breast size are divided into ranges, and different size ranges correspond to different coefficients or deviation values.

[0581] Furthermore, the specific embodiments corresponding to breast size and pressure-bearing capacity can refer to the embodiments corresponding to age, and will not be repeated here.

[0582] Step 3: Control the operation of the breast pump according to the operating parameters.

[0583] In some embodiments, the negative pressure mechanism is a power mechanism of the breast pump, and the control unit controls the negative pressure mechanism to operate according to the operating parameters so that the breast pump operates according to the operating parameters.

[0584] In some embodiments, the breast pump includes a display unit, the display unit including at least one of a first display area and a second display area. After determining the operating parameters of the breast pump according to the user parameters, the method further includes:

[0585] controlling the first display area to display the user parameters; and / or,

[0586] The second display area is controlled to display the operating parameters.

[0587] By controlling the first display area to display user parameters; and / or controlling the second display area to display working parameters, the user can intuitively understand the current status of the breast pump.

[0588] In the fifth embodiment.

[0589] Please refer to Figure 31 again, which is a schematic diagram of the structure of a breast pump provided by the present application. As shown in Figure 31, the breast pump 1 also includes a control interface 113, which includes a first display area 114 and a second display area 115 for indicating whether breast milk is being expressed from the left or right breast. When the breast pump is acting on the right breast, the first display area presents a first display state, and the second display area presents a second display state; when the breast pump is acting on the left breast, the first display area presents a third display state, and the second display area presents a fourth display state; wherein the first display state is different from the third display state, and the second display state is different from the fourth display state.

[0590] In some embodiments, the display parameters included in the above-mentioned display state in the embodiments of the present application include but are not limited to the aspect ratio, color, brightness, area, shape, position, and text indication of the display area, the text being "left" or "right", or "L" or "R".

[0591] For example, the first and third display states may include the text "right" or "R"; the second and fourth display states may include the text "left" or "L", thereby indicating not only by the area but also by the text whether the breast milk stored in the breast pump is expressed from the left or right breast.

[0592] Of course, the present application is not limited to this. Each display state can be combined with parameters such as aspect ratio, color, brightness, area, shape, position, etc., so that the control interface of the breast pump can better express whether the breast milk is sucked from the left breast or the right breast.

[0593] Please refer to Figure 32 again, which is a schematic diagram of a control interface of an embodiment of a breast pump provided by the present application. As shown in Figure 32 , the control interface 113 includes a first display area 114 and a second display area 115 .

[0594] In some embodiments, the control interface 113 further includes one or more of a third display area 116 , a fourth display area 117 , and a fifth display area 118 , which will be specifically introduced in the following embodiments and will not be repeated here.

[0595] In some embodiments, the first display area 114 is located to the right of the second display area 115. When the breast pump is applied to the right breast, the area of ​​the first display area 114 decreases and the area of ​​the second display area 115 increases, so that the first display area is in the first display state and the second display area is in the second display state. For this purpose, please refer to Figure 33, which is a schematic diagram of the control interface 113 formed after the area of ​​the first display area 114 decreases and the area of ​​the second display area 115 increases.

[0596] When the breast pump is acting on the right breast of the person wearing the breast pump, that is, breast milk is expressed from the right breast, if the person is looking directly at the person wearing the breast pump, the breast pump is located on the left hand side of the viewer. Therefore, in the embodiment of the present application, when breast milk is expressed from the right breast, the area of ​​the second display area 115 is increased and the area of ​​the first display area 114 is decreased. Therefore, when the user views the control interface 113 on the breast pump after milk expression, the first display state of the first display area and the second display state of the second display area are the same as the states viewed when the person is looking directly at the breast pump when the breast pump is worn on the right breast (when the breast pump is worn on the right breast and the person is looking directly at the breast pump, the breast pump is located on the left hand side of the person, and the area of ​​the second display area on the left is larger). This allows the user to quickly distinguish that breast milk is expressed from the right breast, making it easier for the user to judge the usage of the breast pump.

[0597] In some embodiments, the first display area 114 is located to the right of the second display area 115. When the breast pump is applied to the left breast, the area of ​​the first display area 114 increases and the area of ​​the second display area 115 decreases, so that the first display area 114 enters the third display state and the second display area 115 enters the fourth display state. For this purpose, please refer to Figure 34, which is a schematic diagram of the control interface 113 after the area of ​​the first display area 114 increases and the area of ​​the second display area 115 decreases.

[0598] When the breast pump is acting on the left breast of the person wearing the breast pump, that is, breast milk is expressed from the left breast, if the person looking directly at the person wearing the breast pump is looking directly at the breast pump, the breast pump is located on the right side of the viewer. Therefore, in the embodiment of the present application, when breast milk is expressed from the left breast, the area of ​​the first display area 114 is increased and the area of ​​the second display area 115 is decreased. As a result, when the user views the control interface 113 on the breast pump after milk expression, the first display state of the first display area and the second display state of the second display area are the same as the states viewed when the person looking directly at the breast pump is worn on the left breast (when the breast pump is worn on the left breast and the person looking directly at the breast pump is looking directly at the breast pump, the breast pump is located on the right side of the person, and the area of ​​the first display area on the right is larger). This allows the user to quickly distinguish that breast milk is expressed from the right breast, making it easier for the user to judge the usage of the breast pump.

[0599] In some embodiments, the first display area 114 includes the word "left" or "L", and the word "left" or "L" will follow the area change of the first display area 114 and always be located in the center of the first display area 114; the second display area 115 includes the word "right" or "R", and the word "right" or "R" will follow the area change of the second display area 115 and always be located in the center of the second display area 115.

[0600] In some embodiments, when the breast pump is not worn by the user, the aspect ratio and area of ​​the first display area 114 and the second display area 115 are equal.

[0601] In some embodiments, the first display area is located to the right of the second display area. When the breast pump is applied to the right breast, the first display area is in the first color and the second display area is in the second color, so that the first display area is in the first display state and the second display area is in the second display state. For this purpose, please refer to Figure 35, which is a schematic diagram of the control interface 113 formed when the first display area 114 is in the first color and the second display area 115 is in the second color.

[0602] In some embodiments, when the breast pump is applied to the left breast, the first display area is in the second color and the second display area is in the first color, so that the first display area is in the third display state and the second display area is in the fourth display state. For this purpose, please refer to Figure 36, which is a schematic diagram of the control interface 113 formed when the first display area 114 is in the second color and the second display area 115 is in the first color.

[0603] In some embodiments, the first color and the second color are colors with strong color contrast, and the first color is brighter than the second color. For example, the first color is white and the second color is black.

[0604] In some embodiments, the brighter color between the first color and the second color is used to indicate the corresponding position of the breast milk in the breast pump; for example, when the color of the first display area is brighter, it means that the breast milk in the breast pump is expressed from the left breast, and when the color of the second display area is brighter, it means that the breast milk in the breast pump is expressed from the right breast.

[0605] By making the first display area and the second display area display different colors, the user can quickly judge the wearing condition of the breast pump according to the color of the first display area and the color of the second display area.

[0606] In some embodiments, when the breast pump is not worn by the user, the first display area 114 and the second display area 115 have the same color.

[0607] In some embodiments, the shapes of the first display area 114 and the second display area 115 are not limited to the rectangles shown in Figures 32, 33, 34, 35, and 36, so in addition to area changes, the first display area 114 and the second display area 115 can also include shape changes.

[0608] In some embodiments, the larger area of ​​the first display area and the second display area is crescent-shaped, i.e., left crescent-shaped or right crescent-shaped, and the smaller area is circular "○"-shaped, and the crescent-shaped area semi-surrounds the circular area.

[0609] In some embodiments, in addition to area changes, the first display area 114 and the second display area 115 also include brightness changes, where the larger area of ​​the first display area 114 and the second display area 115 has higher brightness, and the smaller area has lower brightness.

[0610] In some embodiments, the first display area 114 is not located on the right side of the second display area 115 , but is located above the second display area 115 .

[0611] When the width of the breast pump is small, this arrangement can make greater use of the available space of the breast pump.

[0612] In some embodiments, when the breast pump is applied to the right breast, the first display area 114 presents the third color and the second display area 115 presents the fourth color, so that the first display area 114 forms the first display state and the second display area 115 forms the second display state.

[0613] At this point, please refer to FIG. 37 , which is a schematic diagram of the control interface 113 formed when the first display area 114 is in the third color and the second display area 115 is in the fourth color.

[0614] When the breast pump is applied to the left breast, the first display area 114 presents the fourth color and the second display area presents the third color, so that the first display area 42 forms the third display state and the second display area forms the fourth display state.

[0615] At this point, please refer to FIG. 38 , which is a schematic diagram of the control interface 113 formed when the first display area 114 is in the fourth color and the second display area 115 is in the third color.

[0616] In some embodiments, the third color and the fourth color are colors with a strong color contrast, for example, the third color is white and the fourth color is black.

[0617] In some embodiments, the third color is defined as white, the fourth color is defined as black, and the first display area being white represents that the breast milk in the breast pump is extracted from the right breast, and the second display area being white represents that the breast milk in the breast pump is extracted from the left breast.

[0618] Through the above method, the user can quickly distinguish the wearing position of the breast pump by observing the position of the third color or the fourth color, and the first display area and the second display area are arranged vertically, which can save horizontal space and facilitate the setting of more additional display areas.

[0619] In some embodiments, the shapes of the first display area 114 and the second display area 115 are not limited to the rectangles shown in Figures 37 and 38, and this application does not limit the shapes of the first display area 114 and the second display area 115.

[0620] In some embodiments, the wearing position of the breast pump may be indicated by changing the brightness of the first display area 114 and the second display area 115 .

[0621] For example, when the breast pump is applied to the left breast, the brightness of the first display area 114 is greater than the brightness of the second display area 115 ; when the breast pump is applied to the right breast, the brightness of the first display area 114 is less than the brightness of the second display area 115 .

[0622] In some embodiments, when the breast pump is applied to the right breast, in addition to the color change, the area of ​​the first display area 114 increases and the area of ​​the second display area 115 decreases, so that the first display area 114 forms a first display state and the second display area 115 forms a second display state.

[0623] In some embodiments, when the breast pump is applied to the left breast, in addition to the color change, the area of ​​the first display area 114 decreases and the area of ​​the second display area 115 increases, so that the first display area 114 forms a third display state and the second display area 115 forms a fourth display state.

[0624] The above method increases the visual difference between the first display area 114 and the second display area 115 by changing the color and area of ​​the first display area 114 and the second display area 115 when the breast pump is worn, making it easier for the user to distinguish the wearing position of the breast pump and reducing the user's identification time.

[0625] In some embodiments, the change in area of ​​the first display area 114 and the second display area 115 is achieved by changing the aspect ratio.

[0626] In some embodiments, the first display area 114 and the second display area 115 are defined to present initial colors in an initial state. When a display area changes from the initial color to the third color, the width of the display area remains unchanged and the length increases, thereby increasing the area; when a display area changes from the initial color to the fourth color, the width of the display area remains unchanged and the length decreases, thereby reducing the area.

[0627] In some embodiments, the first display area 114 and the second display area 115 are defined to present initial colors in an initial state. When a display area changes from the initial color to the third color, the length of the display area remains unchanged and the width increases, thereby increasing the area; when a display area changes from the initial color to the fourth color, the length of the display area remains unchanged and the width decreases, thereby decreasing the area.

[0628] Please refer to Figure 39 again, which is a structural diagram of Example 3 of a breast pump provided in an embodiment of the present application.

[0629] As shown in FIG39 , in some embodiments, the breast pump further includes a temperature sensor 110 disposed in the milk storage container portion 50 , and configured to measure the temperature of breast milk in the milk storage container portion 50 . The control interface further includes a third display area 116 , configured to display the temperature measured by the temperature sensor.

[0630] In some embodiments, the temperature sensor 110 is connected to the control unit 30 , and the control unit 30 is configured to receive temperature measurement information from the temperature sensor 110 and display the temperature measurement information in the third display area 116 .

[0631] By providing the temperature sensor 110 in the milk storage container 50 , the temperature of the breast milk stored in the milk storage container 50 can be monitored to prevent the breast milk stored in the milk storage container 50 from being deteriorated due to excessive temperature.

[0632] In some embodiments, breast milk cannot be stored at room temperature for too long. For example, at room temperature, colostrum (milk expressed within 6 days after delivery) can be stored at 27-32°C for 12 hours. Mature breast milk (milk expressed after 6 days after delivery) can be stored at 15°C for 24 hours; at 19-22°C for 10 hours; and at 25°C for 6 hours. Therefore, the breast pump can also be equipped with a timing device to record the storage time of the breast milk in the milk storage container 50, and determine the maximum storage time of the breast milk corresponding to the current temperature based on the temperature sensor. When the storage time of the breast milk in the milk storage container 50 exceeds the maximum storage time corresponding to the temperature sensor, a reminder is issued to the user.

[0633] In some embodiments, the method of issuing a reminder to the user includes but is not limited to the breast pump sending a voice broadcast, or the breast pump sending a reminder message to a terminal connected to it, such as a mobile phone connected to the breast pump by Bluetooth, to prevent breast milk from being stored for too long and deteriorating.

[0634] In some embodiments, the breast pump further includes a control unit 30 , which is connected to the negative pressure mechanism 20 and is used to control the working state of the negative pressure mechanism 20 to facilitate the user to better operate the breast pump.

[0635] In some embodiments, the breast pump further includes a timing subunit 111, which is used to time the working time of the negative pressure mechanism.

[0636] In some embodiments, the control interface further includes a fourth display area 117 in FIG. 32 , and the fourth display area is used to display the timing time of the timing subunit when the negative pressure mechanism starts to work.

[0637] In some embodiments, the control unit 30 is configured to receive timing information from the timing subunit 111 and display the timing information in the fourth display area 117 .

[0638] By displaying the timing time of the timing sub-unit, the user can roughly judge the amount of breast milk currently sucked out by the breast pump through the timing time, which is convenient for the use of the breast pump; and can prevent the wearer from feeling uncomfortable due to the breast pump working for too long.

[0639] In some embodiments, the breast pump further includes a flow sensor 112, and the breast milk sucked out by the breast pump is transferred to the milk storage container portion through the nipple channel, and the flow sensor 112 is arranged in the nipple channel; wherein, the control unit is also connected to the flow sensor 112 and the timing subunit 111, and the control unit 30 is used to calculate the volume of breast milk sucked out by the breast pump based on the flow rate data of the flow sensor 112 and the timing data of the timing subunit.

[0640] In some embodiments, the control unit 30 is further configured to display the calculated volume of breast milk expressed by the breast pump in the fifth display area 118 .

[0641] In some embodiments, the control interface includes a fifth display area 118 , which is used to display the volume of breast milk expressed by the breast pump.

[0642] By setting up a flow sensor and combining it with a timing sub-unit to calculate the volume of breast milk sucked out by the breast pump, the user can know the current amount of breast milk sucked, thus preventing the situation where the amount of breast milk sucked on that day does not meet the standard and is not enough for the baby.

[0643] Please refer to Figure 40 again, which is a schematic diagram of the structure of a terminal device provided in an embodiment of the present application. Terminal device 119 is used to communicate with a breast pump. As shown in Figure 40, terminal device 119 includes a control interface, which includes a first area 120 and a second area 121 for indicating whether breast milk is being expressed from the left or right breast. First area 120 is located above second area 121.

[0644] In some embodiments, the control interface of the terminal device 119 can also view the above-mentioned breast milk temperature, breast milk volume and other information.

[0645] In some embodiments, the control interface of the terminal device 119 can also view the name, age, wearing time and other information of the wearer of the breast pump.

[0646] Please refer to Figure 41 again, which is a schematic diagram of the structure of a system provided by an embodiment of the present application. As shown in Figure 41, the system includes the above-mentioned breast pump 1 and a terminal device 119; wherein the breast pump 1 communicates with the terminal device 119.

[0647] In some embodiments, the breast pump 1 communicates with the terminal device 119 via a wired communication, such as via a Type-C data cable. This application does not limit the specific method of wired communication.

[0648] In some embodiments, the breast pump 1 communicates wirelessly with the terminal device 119, for example, via Bluetooth. This application does not limit the specific method of wireless communication.

[0649] In some embodiments, the breast pump 1 can send various information to the terminal device 119, so that the terminal device 119 displays information including but not limited to breast milk temperature, timing time of the timing subunit, volume of breast milk sucked by the breast pump, etc.

[0650] Through the above method, the user can remotely view the usage of the breast pump, which is convenient for the user.

[0651] In some embodiments, the terminal has a first button. When the first button is triggered, the terminal sends a third message to the breast pump to instruct the breast pump to act on the right breast, so that the first display area presents a first display state and the second display area presents a second display state.

[0652] The terminal also has a second button. When the second button is triggered, the terminal sends a fourth message to the breast pump to instruct the breast pump to act on the left breast, so that the first display area presents the third display state and the second display area presents the fourth display state.

[0653] Through the above method, the user can remotely control the breast pump, or control the breast pump without touching the breast pump, which is convenient for the user to use the breast pump in an area that is not private enough.

[0654] In some embodiments, the terminal further has a third button, which is used to control the working state of the negative pressure mechanism to control whether the breast pump is sucking milk.

[0655] In some embodiments, a refrigeration unit and a temperature sensor are provided in the milk storage container portion of the breast pump, and the terminal is also provided with a fourth button, which is used to control whether the refrigeration unit is refrigerated, so that when the user observes that the temperature of the breast milk in the milk storage container portion is too high, the refrigeration unit can be operated by the fourth button to control the temperature of the breast milk and extend the storage time of the breast milk.

[0656] Please refer to Figure 42, which is a flow chart of a control method provided by an embodiment of the present application. As shown in Figure 42, the control method includes: a first step to a second step.

[0657] Step 1: Acquire indication information; wherein, the indication information is used to indicate whether the breast milk stored in the breast pump is sucked from the left breast or the right breast.

[0658] In some embodiments, the step of obtaining indication information includes the following steps.

[0659] (1) Obtaining the indication information sent by the terminal communicating with the breast pump.

[0660] In some embodiments, the terminal sends instruction information to the breast pump to indicate whether the breast milk stored in the breast pump is sucked from the left breast or the right breast, such as the third information and the fourth information mentioned above.

[0661] In some embodiments, the breast pump is provided with two buttons, which are used to record the extraction of breast milk from the left breast and the extraction of breast milk from the right breast, respectively, and the indication information is generated by triggering the buttons.

[0662] In some implementations, obtaining indication information includes the following steps.

[0663] (1) Acquiring detection information from a detection sensor, wherein the detection sensor is used to detect the working position of the breast pump.

[0664] (2) Determine the indication information according to the detection information.

[0665] In some embodiments, the breast pump can be worn in a matching bra, and a detection element can be provided on the bra. The detection sensor determines the active position of the breast pump by detecting the detection element in the bra.

[0666] In some embodiments, a detection element is provided on one side of the bra, such as the left breast, and no detection element is provided on the other side of the bra, such as the right breast. The detection sensor generates detection information by detecting the presence or absence of the detection element.

[0667] For example, the detection sensor obtains first detection information when worn on the left breast, and obtains second detection information when worn on the right breast, so that the breast pump determines the action position according to the detection information.

[0668] In some embodiments, detection elements are provided on both sides of the bra, but the detection elements carry different labels. The detection sensor generates detection information by detecting the labels on the detection elements.

[0669] In some embodiments, the detection sensor includes a Hall sensor, an RFID reader, etc., which is not limited in this application.

[0670] The detection information obtained by the detection sensor allows the breast pump to know the current action position and control the display status of the first display area and the second display area to record the breast milk extraction position for user convenience.

[0671] Step 2: Control the display states of the first display area and the second display area according to the indication information; wherein, when the breast pump acts on the right breast, the first display area is controlled to present a first display state, and the second display area is controlled to present a second display state; when the breast pump acts on the left breast, the first display area is controlled to present a third display state, and the second display area is controlled to present a fourth display state; wherein, the first display state is different from the third display state, and the second display state is different from the fourth display state.

[0672] In some embodiments, the first display area is located on the right side of the second display area, and the step of controlling the display states of the first display area and the second display area according to the indication information includes the following steps.

[0673] (1) when it is determined according to the indication information that the breast pump is acting on the right breast, controlling the area of ​​the first display area to decrease and controlling the area of ​​the second display area to increase, so that the first display area forms a first display state and the second display area forms a second display state;

[0674] (2) When it is determined according to the indication information that the breast pump is acting on the left breast, the area of ​​the first display area is controlled to increase and the area of ​​the second display area is controlled to decrease, so that the first display area forms a third display state and the second display area forms a fourth display state.

[0675] In some embodiments, the first display area is located on the right side of the second display area, and the step of controlling the display states of the first display area and the second display area according to the indication information includes the following steps.

[0676] (1) when it is determined according to the indication information that the breast pump is acting on the right breast, controlling the first display area to be in a first color and controlling the second display area to be in a second color, so that the first display area forms a first display state and the second display area forms a second display state;

[0677] (2) When it is determined according to the indication information that the breast pump is acting on the left breast, the first display area is controlled to be in the second color and the second display area is controlled to be in the first color, so that the first display area forms a third display state and the second display area forms a fourth display state.

[0678] In some embodiments, the first display area is located above the second display area, and the step of controlling the display states of the first display area and the second display area according to the indication information includes the following steps.

[0679] (1) When it is determined according to the indication information that the breast pump is acting on the right breast, the first display area is controlled to present a third color and the second display area is controlled to present a fourth color, so that the first display area forms a first display state and the second display area forms a second display state.

[0680] (2) When it is determined according to the indication information that the breast pump is acting on the left breast, the first display area is controlled to present a fourth color and the second display area is controlled to present a third color, so that the first display area forms a third display state and the second display area forms a fourth display state.

[0681] In some implementations, the display control method for a breast pump provided in the embodiments of the present application further includes the following steps.

[0682] (1) when it is determined according to the indication information that the breast pump is acting on the right breast, controlling the area of ​​the first display area to increase and controlling the area of ​​the second display area to decrease, so that the first display area forms a first display state and the second display area forms a second display state;

[0683] (2) When it is determined according to the indication information that the breast pump is acting on the left breast, the area of ​​the first display area is controlled to decrease, and the area of ​​the second display area is controlled to increase, so that the first display area forms a third display state and the second display area forms a fourth display state.

[0684] In the sixth embodiment.

[0685] 43 , an embodiment of the present invention provides a control method, which includes: first to third steps.

[0686] The first step is to receive the preset user parameter information of the current user;

[0687] In order to adapt to the situation where different users have different preset user parameter information, after receiving the preset user parameter information of the current user, a matching breast pumping control mode can be recommended to the current user based on the preset user parameter information.

[0688] The second step is to input the preset user parameter information into the breast pumping control model for matching to obtain an initial breast pumping control mode;

[0689] The breast pumping control model stores a large amount of data collected based on different preset user parameter information, dividing it into multiple preset breast pumping control modes corresponding to the various preset user parameter information. Furthermore, upon receiving the preset user parameter information of the current user, it can provide an appropriate initial breast pumping control mode for the user. However, it should be noted that although the initial control mode is the result of data matching based on the current user's physical parameters, it is not necessarily the optimal breast pumping control mode for a specific user, but rather serves as a relatively reasonable control mode for the current user in the initial stage of breast pump use.

[0690] The third step is to output initial control data information according to the initial breast pumping control mode, so as to drive the target breast pump to operate according to the initial control data information.

[0691] Among them, after obtaining the corresponding initial control mode through the second step, the smart mobile terminal outputs the corresponding initial control data information according to the initial control mode. The current user can then control the operation of the target breast pump on the smart mobile terminal according to the initial control data information provided by the smart mobile terminal, or directly input the relevant initial control data information on the control interface of the target breast pump to control the operation of the target breast pump.

[0692] A control method according to an embodiment of the present invention receives preset user parameter information of a current user, performs matching in a breast pumping control model according to the preset user parameter information to obtain an initial breast pumping control mode adapted to the preset user parameter information, and outputs initial control data information according to the initial breast pumping control mode to drive a target breast pump to operate. This method solves the technical problem in related arts that breast pump devices cannot provide different breast pump control modes according to the preset user parameter information of different users, thereby resulting in low breast pumping efficiency and poor user experience.

[0693] Referring to Figure 44 , in some embodiments, the initial control mode is directly outputted after matching the preset user parameter information of the current user within the breast pump control model. However, the amount of milk expressed using a breast pump is not only affected by the preset user parameter information but also by other factors in actual use, such as the current user's dietary habits, resting habits, environmental factors, and other physiological parameters (e.g., the duration of a woman's menstrual period). Therefore, after obtaining the corresponding initial breast extraction control mode based on the preset user parameter information, it is necessary to adjust it based on the current user's actual usage to obtain a target breast extraction control mode that suits the current user. Therefore, in this embodiment, the control method further includes steps 4 to 6.

[0694] Step 4: Receive historical breast pumping data information of the current user;

[0695] In order to provide the current user with a breast pump control mode that suits the current user, it is necessary to obtain historical breast pumping data information when the current user uses the breast pump to pump milk.

[0696] Step 5: generating a target breast pumping control mode based on the historical breast pumping data information and the initial breast pumping control mode;

[0697] Among them, after obtaining the historical breast pumping data information, it is necessary to judge whether the initial breast pumping control mode is the optimal breast pumping control mode for the current user based on it. If not, the initial breast pumping control mode needs to be adjusted according to the historical breast pumping data information to obtain the target breast pumping control mode that meets the preset user parameter information of the current user.

[0698] Step 6: outputting target control data information according to the target breast pumping control mode, so as to drive the target breast pump to operate according to the target control information.

[0699] Among them, after obtaining the target breast pumping control mode in step 5, the smart mobile terminal outputs corresponding target control data information according to the target control mode, and the current user can control the operation of the target breast pump on the smart mobile terminal according to the target control data information provided by the smart mobile terminal, or directly input relevant target control data information on the control interface of the target breast pump to control the operation of the target breast pump.

[0700] Referring to Figure 45 , in some embodiments, the user's actual breast pumping operation using the breast pump is likely not to be performed entirely in accordance with the initial breast pumping control mode in step 3. Therefore, in the aforementioned embodiment, after receiving the historical breast pumping data of the user, step 4 further includes filtering the historical breast pumping data, such that the filtered historical breast pumping data corresponds to breast pumping data collected in the initial breast pumping control mode. In this embodiment, step 5 of the aforementioned embodiment generates a target breast pumping control mode based on the historical breast pumping data and the initial breast pumping control mode, specifically including the following sub-steps:

[0701] (1) Obtaining the average amount of milk expressed over multiple historical breast pumping data;

[0702] The average amount of milk expressed is obtained based on historical breastfeeding data from a preset number of times. The specific preset number of times can be adaptively set according to different application scenarios. Generally, too few preset times can easily lead to inaccurate results in subsequent steps, while too many preset times can make it impossible to quickly provide the user with an adapted target breastfeeding control mode. Therefore, the preset number of times (i.e., corresponding to the "multiple" in this step) is set between 5 and 10 times.

[0703] (2) determining whether the average amount of milk expressed is within or greater than the range of milk expressed corresponding to the initial milk expression control mode;

[0704] Among them, the milk extraction volume interval corresponding to the initial milk extraction control mode is the amount of milk that the breast pump can extract in a single breast according to the initial control mode. The initial milk extraction control mode obtained according to the preset user parameter information corresponds to a preset milk extraction volume interval. The milk extraction volume intervals corresponding to different milk extraction control modes may be the same or different, or may be partially the same. For example, the milk extraction volume interval of one milk extraction control mode is 100-120ml, while the milk extraction volume interval of another milk extraction control mode is 115-130ml. The settings of these milk extraction volume intervals are all based on the preset user parameter information after collecting a large amount of user preset user parameter information; or they are intervals obtained by scientific calculation based on the user preset user parameter information.

[0705] If yes, then perform the following steps:

[0706] (3) The target breast pumping control mode is the same as the initial breast pumping control mode;

[0707] If, in step (2), the average amount of milk extracted by the current user using the breast pump under the initial breast pumping control mode is within or greater than the breast pumping amount interval corresponding to the initial breast pumping control mode, then it means that the current user can achieve a reasonable breast pumping efficiency and amount of milk extracted that conform to the preset user parameter information by using the breast pump device under the initial breast pumping control mode. Therefore, the initial breast pumping control mode is recommended to the current user as the target breast pumping control mode, so that the current user uses the breast pump according to the target breast pumping control mode.

[0708] Otherwise, perform the following steps:

[0709] (4) Modify the initial breast pumping control mode according to the preset adjustment mechanism to generate a target breast pumping control mode.

[0710] Among them, if the average amount of milk sucked by the current user after using the breast pump to express milk according to the initial milk sucking control mode is less than the milk sucking amount range corresponding to the initial milk sucking control mode, it means that the initial milk sucking control mode is not completely suitable for the current user. Therefore, it is necessary to modify the initial milk sucking control mode and output a target milk sucking control mode that meets the current user's needs to improve its milk sucking efficiency.

[0711] In some embodiments, the target control data information included in the target breast pumping control mode includes a target breast pumping pressure, a target breast pumping time point, and a target breast pumping duration. Among them, the target breast pumping pressure is the breast pumping pressure generated by driving the breast pump to work, which is a pressure value or a pressure range. The target breast pumping time point includes one or more time points in a day, and the time point can be a time point in a certain time period, such as a time point from 9:00 am to 10:00 am in a day. The target breast pumping duration is the time taken from starting to use the breast pump to completing the breast pumping process within the time point. In this embodiment, if the average value (actual value) of the breast pumping amount obtained by the current user through the above embodiment using the initial breast pumping control mode is less than the breast pumping amount interval (preset value) corresponding to the initial breast pumping control mode, it means that the initial breast pumping control mode needs to be adjusted to obtain the target breast pumping control mode that adapts to the current user; then step (4) of the above embodiment modifies the initial breast pumping control mode according to the preset adjustment mechanism to generate the target breast pumping control mode, including the steps of:

[0712] (41) obtaining the initial milk pumping pressure, initial milk pumping time point, and initial milk pumping duration corresponding to the initial milk pumping control mode;

[0713] In this embodiment, the initial breast pumping control mode is adjusted by increasing the initial pressure. The adjustment method includes any one of the following:

[0714] (42) The target sucking pressure is obtained by adding the initial sucking pressure to the preset pressure adjustment value, the initial sucking time is the target sucking time, and the initial sucking time is the target sucking time;

[0715] This adjustment method only adjusts the initial pressure, while the target extraction time and target extraction duration still use the initial extraction time and duration corresponding to the initial extraction control mode. This method increases the extraction pressure to improve the efficiency of the breast pump used by the current user. Furthermore, the preset pressure adjustment value should be set to a reasonable value and should not be set to a large value that could harm the current user. A gradual adjustment method can be used, where the preset pressure adjustment value is set to a relatively small value, then adjusted incrementally, and finally, after confirmation by the current user, the adjusted pressure value is used as the target extraction pressure.

[0716] or,

[0717] (43) The target sucking pressure is obtained by adding the initial sucking pressure to the preset pressure adjustment value, the target sucking time is obtained by adding the initial sucking time to the preset time adjustment value, and the initial sucking time is the target sucking time;

[0718] Among them, this adjustment method is to adjust the initial milk extraction pressure and the initial milk extraction time at the same time to obtain the corresponding target milk extraction pressure and target milk extraction time point, while still using the initial milk extraction time as the target milk extraction time.

[0719] or,

[0720] (44) The target sucking pressure is obtained by adding the initial sucking pressure to the preset pressure adjustment value, the target sucking time is obtained by adding the initial sucking time to the preset time adjustment value;

[0721] Among them, the adjustment method is to adjust the initial breast pumping pressure and the initial breast pumping time to obtain the corresponding target breast pumping pressure and target breast pumping time, while still using the initial breast pumping time point as the target breast pumping time point.

[0722] or,

[0723] (45) The target milking pressure is obtained by adding the initial milking pressure to the preset pressure adjustment value, the target milking time is obtained by adding the initial milking time point to the preset time point adjustment value, and the target milking time is obtained by adding the initial milking time to the preset time adjustment value.

[0724] Among them, the adjustment method is to adjust the initial milk extraction pressure, the initial milk extraction time point and the initial milk extraction duration to obtain the corresponding target milk extraction pressure, the target milk extraction time point and the target milk extraction duration.

[0725] In some embodiments, the target milking control mode is obtained by adjusting the initial milking pressure as the target milking pressure and then adjusting one or more of the initial milking time point and the initial milking duration. Specifically, the adjustment method includes any of the following:

[0726] (46) The initial suckling pressure is the target suckling pressure, the target suckling time is obtained by adding the initial suckling time point to the preset time point adjustment value, and the initial suckling time is the target suckling time;

[0727] The adjustment method is to adjust the initial milk pumping time point to the corresponding target milk pumping time point, and the initial milk pumping pressure is used as the target milk pumping pressure, and the initial milk pumping time is used as the target milk pumping time.

[0728] or,

[0729] (47) The initial suckling pressure is the target suckling pressure, the target suckling time is obtained by adding the initial suckling time point to the preset time point adjustment value, and the target suckling time is obtained by adding the initial suckling time to the preset time adjustment value;

[0730] Among them, the adjustment method is to adjust the initial milk extraction time point and the initial milk extraction duration to obtain the target milk extraction time point and the target milk extraction duration, and the initial milk extraction pressure is used as the target milk extraction pressure.

[0731] or,

[0732] (48) The initial milk extraction pressure is the target milk extraction pressure, the initial milk extraction time point is the target milk extraction time point, and the target milk extraction time is obtained by adding the initial milk extraction time and the preset time adjustment value.

[0733] The adjustment method is to adjust the initial breast pumping time to obtain the target breast pumping time, and the initial breast pumping pressure is used as the target breast pumping pressure, and the initial breast pumping time point is used as the target breast pumping time point.

[0734] In some embodiments, in the process of modifying the initial breast pumping control mode according to the preset adjustment mechanism to generate the target breast pumping control mode in the above embodiments, the adjustment of the initial breast pumping pressure, the initial breast pumping time, or the initial breast pumping duration is performed in a small-scale modification manner. Then, after each target breast pumping control mode is obtained, the milk volume extracted by the current target breast pumping control mode is compared with the milk volume range corresponding to the initial breast pumping control mode to determine whether it meets the requirements, thereby determining whether to modify the initial breast pumping control mode through other adjustment methods to generate the final target breast pumping control mode. In addition, in some cases, even if the target breast pumping control mode is modified according to the above embodiments in all cases, the milk volume extracted by driving the breast pump is still not greater than or within the milk volume range corresponding to the initial breast pumping control mode, then the target breast pumping control mode corresponding to the largest milk volume is selected as the final target breast pumping control mode according to the principle of sorting the milk volume from highest to lowest.

[0735] In some embodiments, after obtaining the target breast pumping control mode corresponding to the current user through any of the above embodiments, the target breast pumping control mode is bound to the current user. Specifically, after the current user logs in to the breast pump control application on the smart mobile device through identity authentication, the application assigns a unique ID to the current user. Furthermore, after the obtained target breast pumping control mode is bound to the unique ID, even if the user changes the smart mobile terminal or breast pump, the user can still obtain the target breast pumping control mode that suits them by logging in to the breast pump control application.

[0736] In some embodiments, because the amount of milk expressed during breast pump operation is related to the user's age, breast size, season, and region of use, the preset user parameter information described in the above embodiments includes one or more of the following: age, breast size, season, and region of use. Typically, to provide users with more accurate breast pump control modes, the preset user parameter information includes age, breast size, season, and region of use. Therefore, the breast pump control model stores multiple initial breast pump control modes corresponding to combinations of various age, breast size, season, and region of use information. The various regions of use are typically categorized by the country in which the target breast pump is used. These corresponding breast pump control modes are the result of analyzing and filtering a large amount of data collected based on the preset user parameter information. In this embodiment, because the breast pump is used in different regions and at different times, corresponding breast pump control modes are set for different regions or seasons of use. This means that users in different regions, even those with the same season, age, and breast size, will have different initial breast pump control modes. Alternatively, even for users of the same region, age, and breast size, different initial breast pumping control modes may be used in different seasons (e.g., winter and summer). In one specific example, after the current user manually inputs preset user parameter information through a device connected to the target breast pump (e.g., a mobile phone or pad), or the device provides a selection interface for the user to select and input preset user parameter information, the device matches the corresponding initial breast pumping control mode in the breast pump control model based on the received preset user parameter information. The device then displays the corresponding initial control data information on the device interface based on the initial control mode, allowing the user to control the target breast pump according to the initial control data information. Furthermore, the device also provides a control interface for the target breast pump, through which the user can control the target breast pump according to the initial control data information.

[0737] In the seventh embodiment.

[0738] As shown in Figures 46-47, when using the breast pump of the present invention, the breast shield 10 is held and closely attached to the breast. When the negative pressure mechanism 20 is in operation, breast milk is extracted from the breast under the negative pressure generated by the negative pressure mechanism 20 and stored in the milk storage container 50 through the nipple channel 12. The breast pump of the present invention is also equipped with a stimulation unit 220, which is electrically connected to and controlled by the control unit. The control unit can respond to a user-input activation command or generate a corresponding activation signal based on sensor detection data. The activation signal activates the stimulation unit to begin operating in a preset mode, which includes at least a first mode that stimulates the breast to generate heat, thereby unblocking blocked mammary glands and causing the breast to produce milk ejection.

[0739] In some embodiments, the breast pump further comprises a housing, on which at least one button is provided, and a user can trigger the generation of a start instruction by triggering the button.

[0740] In some embodiments, the breast pump further includes a communication unit, through which the breast pump can communicate with an external terminal. The user can input a start instruction on the external terminal, and the start instruction is sent to the control unit of the breast pump via the communication unit to be received by the control unit.

[0741] Specifically, in some embodiments, the stimulation unit 220 includes an infrared generator 221. Upon receiving a corresponding activation signal, the control unit controls the infrared generator to radiate infrared light toward the breast, thereby stimulating the breast to heat. The infrared generator's heating technology involves irradiating the infrared light onto the object being heated. While the infrared light is reflected and transmitted, the remaining light is absorbed by the object and converted into thermal motion of its molecules, thereby heating the object.

[0742] Furthermore, in some embodiments, the far-infrared radiation emitted by infrared generator 221 has a wavelength of 4-14 μm. Human skin is 70% water, which is a good absorber of far-infrared radiation. Therefore, the breast's absorption spectrum for far-infrared radiation is similar to that of water, with two absorption peaks at 2.5-4 μm and 5.6-10 μm. Therefore, far-infrared radiation with a wavelength of 4-14 μm is well absorbed by the breast.

[0743] In some embodiments, the wavelength of the far infrared ray radiated by the infrared generator 221 is 4 μm, 9 μm, or 14 μm.

[0744] Furthermore, infrared generator 221 is located on the side of breast shield 10 facing away from the breast. Since breast shield 10 rests closely on the skin of the breast, placing infrared generator 221 on breast shield 10 brings the far-infrared radiation source closer to the breast. Furthermore, infrared generator 221 is located on flange 11 of breast shield 10 to prevent direct contact with the skin and possible discomfort.

[0745] Furthermore, in some embodiments, the breast pump is equipped with a temperature sensor 223 for detecting the temperature of the breast surface. The temperature sensor 223 is electrically connected to the control unit. When the infrared generator 221 begins operating, the temperature sensor 223 also begins operating in real time. If the temperature sensor 223 detects that the breast surface temperature exceeds a certain value, the control unit controls the infrared generator 221 to stop operating, thereby preventing excessive breast temperature and burns.

[0746] Optionally, the temperature sensor 223 includes a contact temperature sensor 223 and a non-contact temperature sensor 223. The contact temperature sensor 223 is arranged on the surface of the flange 11 and is in direct contact with the breast, so as to well detect the breast temperature; the non-contact sensor can be arranged on the inside or outside of the flange 11. The type of the temperature sensor 223 is not specifically limited in the present invention.

[0747] Furthermore, in some embodiments, the breast pump is further provided with a flow sensor 224 for detecting the flow rate of breast milk extracted by the breast pump. This flow sensor 224 is electrically connected to the control unit and is located in the nipple passage 12. Breast milk passes through the nipple passage 12 and is collected by the milk storage container 50. The flow sensor 224, located in the nipple passage 12, can accurately detect the flow rate of collected breast milk in real time and feed this flow rate information back to the control unit. Based on the flow rate, the control unit controls the operating mode of the breast pump.

[0748] Furthermore, in some embodiments, the breast pump also includes a massage assembly 222 disposed on the breast shield 10. The massage assembly 222 is electrically connected to the control unit and is directly controlled by the control unit. Specifically, it comprises a plurality of protrusions disposed on the flange 11 and a plurality of vibrators disposed within the main unit 2. The vibrators fit tightly against the flange 11. When the vibrators are in operation, the vibrations generated act on the flange 11, driving the protrusions to vibrate, thereby massaging the breasts. By massaging the breasts, the massage assembly 222 improves blood circulation, promotes breast milk secretion, and effectively dredges the breast meridians and milk ducts.

[0749] Refer to Figure 48. As shown in Figure 48, the control method provided in the embodiment of the present application includes: first step to fifth step.

[0750] The first step: generating a corresponding start signal in response to a start instruction input by a user or according to detection data of a sensor.

[0751] In some embodiments, the generation of the activation signal can be controlled by the user. The user can send a command to activate the corresponding lactation induction mode to the breast pump via a terminal. The control unit receives the activation signal and activates the corresponding lactation induction mode. In some examples, the breast pump may be provided with a switch button for the corresponding lactation induction mode. When the user turns on the switch button, the control unit sends a command to activate the corresponding lactation induction mode. The control unit receives the activation signal and controls the stimulation unit 220 to operate.

[0752] In some embodiments, the start signal may be generated by sensor detection data, such as by a flow sensor detecting the flow rate of expressed breast milk, or by an ambient temperature sensor disposed on the housing detecting the ambient temperature.

[0753] The second step: starting the stimulation unit according to the starting signal to start working in a preset mode, wherein the preset mode at least includes a first mode for stimulating the breast to generate heat.

[0754] In some embodiments, the preset modes include at least a first mode, which is used to stimulate the breast to generate heat, so as to solve the problem that traditional hot compress methods easily burn the skin and better clear blocked mammary glands.

[0755] In some embodiments, the second step includes the following steps.

[0756] (1) controlling the infrared generator of the stimulation unit to start working to enter the first mode;

[0757] (2) Alternatively, controlling the stimulation unit to enter a second mode, in which the infrared generator stops working and the massage component of the stimulation unit starts working to massage the breast;

[0758] (3) Alternatively, the stimulation unit is controlled to enter a third mode, in which the infrared generator and the massage component of the stimulation unit start to work, so as to massage the breast while stimulating the breast to generate heat.

[0759] In some embodiments, massage by means of a massage component can also have the effect of clearing milk blockage.

[0760] In some embodiments, the breast pump includes a first button, a second button, and a third button. When the user triggers the first button, a start-up instruction for entering the first mode is generated; when the user triggers the second button, a start-up instruction for entering the second mode is generated; and when the user triggers the third button, a start-up instruction for entering the third mode is generated.

[0761] In some embodiments, the breast pump includes a flow sensor. When the flow rate detected by the flow sensor is in different ranges, different start instructions will be generated. The details will be introduced in the following part of the specification and will not be repeated here.

[0762] In some embodiments, the breast pump includes an ambient temperature sensor, and different start-up instructions are generated when the ambient temperature detected by the ambient temperature sensor is in different ranges.

[0763] Exemplarily, when the ambient temperature is less than the first ambient temperature threshold, a startup instruction for entering the third mode is generated; when the ambient temperature is greater than or equal to the first ambient temperature threshold and less than the second ambient temperature threshold, a startup instruction for entering the second mode is generated; when the ambient temperature is greater than or equal to the second ambient temperature threshold, a startup instruction for entering the first mode is generated.

[0764] Among them, the ambient temperature sensor can be set on the shell to measure the room temperature. When the ambient temperature is low, that is, less than the first ambient temperature threshold, the blood is not circulating due to the cold, and the probability of milk blockage is high. Therefore, the third mode is entered at this time, and the breasts are heated and massaged at the same time; when the ambient temperature is moderate, that is, the ambient temperature is greater than or equal to the first ambient temperature threshold and less than the second ambient temperature threshold, only the breasts are massaged; when the ambient temperature is high, only the breasts are stimulated to heat up.

[0765] The above method provides three modes of operation of the stimulation unit, allowing users to choose according to their own needs, or make intelligent choices based on sensor data, thereby improving the user experience.

[0766] In some embodiments, the first step includes the following steps.

[0767] A corresponding start signal is generated according to the flow rate detected by the flow sensor when the breast pump is sucking out breast milk.

[0768] In some embodiments, the step of generating a corresponding start signal according to the flow rate of the breast pump when sucking out breast milk detected by the flow sensor includes the following steps.

[0769] (1) generating a first start signal when the flow rate is less than a first flow rate threshold and greater than or equal to a second flow rate threshold;

[0770] At this time, the second step includes the following steps.

[0771] (2) According to the first start signal, the infrared generator of the stimulation unit is controlled to start working to enter the first mode.

[0772] Specifically, when the breast pump is sucking milk, the flow sensor detects the flow of breast milk flowing into the milk storage container 50. When the flow is less than the first flow threshold and greater than or equal to the second flow threshold, it means that the flow is large, which only stimulates the breast to heat up and prevent milk blockage.

[0773] In some embodiments, the step of generating a corresponding start signal according to the flow rate of the breast pump when sucking out breast milk detected by the flow sensor includes the following steps.

[0774] (1) generating a second start signal when the flow rate is less than a second flow rate threshold and greater than or equal to a third flow rate threshold;

[0775] At this time, the second step includes the following steps.

[0776] (2) According to the second start signal, the stimulation unit is controlled to enter a second mode, in which the infrared generator stops working and the massage component of the stimulation unit starts working to massage the breast.

[0777] Specifically, when the breast pump is used to express milk, the flow sensor detects the flow rate of breast milk flowing into the milk storage container 50. When the flow rate is less than the second flow rate threshold and greater than or equal to the third flow rate threshold, it indicates that the flow rate is moderate and only massage is performed.

[0778] Furthermore, in most cases, stimulating breast heating through an infrared generator is a non-contact method, which is gentler and provides a more comfortable user experience. However, it is slow to take effect because it requires a certain amount of heating time. Therefore, if the flow rate is large, it means that the user is less likely to have milk blockage, and at this time only the breast is stimulated for heating. The massage component massage method takes effect faster, but requires contact with the user's breast, which may cause discomfort to the user. Therefore, massage is only used when the flow rate is moderate.

[0779] In some embodiments, the step of generating a corresponding start signal according to the flow rate of the breast pump when sucking out breast milk detected by the flow sensor includes the following steps.

[0780] (1) When the flow rate is less than a third flow rate threshold, the flow sensor generates a third start signal;

[0781] At this time, the second step includes the following steps.

[0782] (2) According to the third start signal, the stimulation unit is controlled to enter a third mode, in which the infrared generator and the massage component of the stimulation unit start to work to massage the breast while stimulating the breast to generate heat.

[0783] Specifically, when the breast pump is sucking milk, the flow sensor detects the flow rate of breast milk flowing into the milk storage container portion 50. When the flow rate is less than the third flow rate threshold, it indicates that the flow rate is small. At the same time, the breast is stimulated to heat up and massage to clear the milk blockage to the greatest extent, increase the amount of breast milk sucked, and prevent insufficient breast milk from being sucked out.

[0784] In an embodiment of the present invention, the preset first, second, and third flow rate thresholds are based on the average flow rate of different women during normal breast pumping using a breast pump, as measured by large data sets. If the flow rate does not reach the average flow rate, lactation induction is required, and breast pumping is resumed after lactation induction. If the flow rate exceeds the average breast milk volume, the control unit does not activate the lactation induction mode and maintains its current operation.

[0785] In some implementations, the first flow threshold is determined by an average flow rate.

[0786] Exemplarily, the first flow threshold is equal to the average flow, or is the average flow*preset proportional coefficient, where the preset proportional coefficient is, for example, 0.9 or 1.1.

[0787] At this time, when the average flow rate measured by the big data changes, the first flow rate threshold will also change.

[0788] In some embodiments, the moderate flow rate mentioned above refers to a moderate difference from the average flow rate, the large flow rate refers to a small difference from the average flow rate, and the small flow rate refers to a large difference from the average flow rate.

[0789] In some embodiments, different modes can be switched freely. Before switching to a new mode, the current mode must be stopped first. For greater convenience, during the mode switching process, if a working unit that needs to be turned on, such as the infrared generator and massage component, is already in operation, it is only necessary to keep the working unit running without repeatedly turning it off and on again to avoid wasting energy.

[0790] In some embodiments, the maximum operating time of the three modes can be adjusted and does not need to be consistent. After the maximum operating time is reached, the control unit will control the breast pump to exit the current mode.

[0791] In some implementations, the method in this embodiment may include only the first step and the second step.

[0792] Step 3: Obtaining the continuous working time of the stimulation unit;

[0793] Step 4: Determine whether the continuous working time is greater than a preset time threshold;

[0794] In some implementations, the preset time threshold is factory set and can be set by the user after leaving the factory.

[0795] Step 5: After determining that the continuous working time is greater than the preset time threshold, the infrared generator and / or massage component of the stimulation unit in the working state is controlled to stop working, and the negative pressure mechanism of the breast pump is started to perform milk suction.

[0796] In some embodiments, the control unit includes a timing module, and the timing module in the control unit records the continuous working time of the stimulation unit.

[0797] Through the above method, the user's breasts can be fully massaged before milk suction, which can timely dredge the breasts and prevent milk blockage.

[0798] In some embodiments, please refer to Figure 49, which is a flow chart of a third embodiment of a control method provided by an embodiment of the present application. As shown in Figure 49, the control method includes: steps 6 to 10.

[0799] Step 6: generating a corresponding start signal in response to a start instruction input by the user or according to detection data of the sensor;

[0800] Step 7: starting the stimulation unit according to the starting signal to start working in a preset mode, wherein the preset mode at least includes a first mode for stimulating the breast to generate heat.

[0801] Step 8: controlling the temperature sensor to detect the temperature of the breast surface;

[0802] Step 9: Determine whether the temperature is greater than a preset temperature threshold;

[0803] In some embodiments, the preset temperature threshold is factory set and can be set by the user after leaving the factory.

[0804] In some embodiments, the preset temperature threshold is limited to be set too high and needs to be lower than the temperature that will burn human skin. For example, the maximum temperature can only be 45° C. to prevent burns to the skin.

[0805] In some embodiments, the preset temperature threshold is limited to be set too low and cannot be lower than the normal human body temperature, such as 36°C, to avoid the stimulation unit being terminated as soon as it starts working and failing to clear the blocked milk duct.

[0806] Step 10: After determining that the temperature of the breast surface is greater than the preset temperature threshold, the infrared generator and / or massage component of the stimulation unit in the working state is controlled to stop working, and the negative pressure mechanism of the breast pump is started to perform milk suction.

[0807] In some embodiments, after determining that the temperature of the breast surface is greater than the preset temperature threshold, it is considered that the stimulation unit has sufficiently stimulated the breast and milk extraction can begin.

[0808] In the eighth embodiment.

[0809] In some embodiments, performing a preset operation according to the control parameter includes:

[0810] A preset operation is performed according to the volume of breast milk stored in the milk storage container portion.

[0811] In some embodiments, the preset operation performed according to the volume of breast milk stored in the milk storage container portion includes: displaying the volume of breast milk stored in the milk storage container portion on a display interface of the breast pump, and sending information to a terminal to display the volume of breast milk stored in the milk storage container portion.

[0812] Please refer to Figure 50, which is a flow chart of a control method provided in an embodiment of the present application. As shown in Figure 50, the control method includes the first step to the third step.

[0813] The first step is to control the first measuring unit to measure the liquid level of the milk storage container.

[0814] In some embodiments, the first measurement unit is a time of flight (TOF) sensor.

[0815] Optionally, the TOF sensor is arranged on the top of the milk storage container portion.

[0816] In some embodiments, the first measurement unit includes a plurality of liquid level sensors.

[0817] Optionally, a plurality of liquid level sensors are arranged on the side wall of the milk storage container at a certain interval.

[0818] The second step: controlling the second measuring unit to measure the tilt angle of the milk storage container.

[0819] In some embodiments, the second measuring unit is a three-axis acceleration sensor, and the second measuring unit is used to measure the three-axis acceleration of the milk storage container.

[0820] In some embodiments, the calculation formula of the tilt angle α is as follows:

[0821] Wherein, z is the z-axis acceleration measured by the three-axis accelerometer, and g is the acceleration due to gravity.

[0822] In some embodiments, the second step includes the following steps.

[0823] (1) When the first volume is within a first volume range, the second measuring unit is controlled to measure the tilt angle of the milk storage container portion.

[0824] In some embodiments, when the volume of breast milk stored in the milk storage container is too little or too much, the measurement error is small and the volume may not be corrected.

[0825] In some embodiments, the first volume range is [10 mL, 150 mL].

[0826] The third step is to determine the volume of the breast milk stored in the milk storage container according to the liquid level and the tilt angle.

[0827] In some embodiments, the third step includes the first sub-step (1) to the third sub-step (3).

[0828] First sub-step (1): determining a first volume of breast milk stored in the milk storage container portion according to the liquid level.

[0829] In some embodiments, the measured liquid level height is not a specific value, but multiple values ​​within a range. In particular, when the milk storage container is tilted, multiple liquid level heights will be measured because the liquid level is also tilted. In this case, a value within the liquid level height range can be selected according to a selection rule to be determined as the liquid level height for use in subsequent calculation steps.

[0830] In some embodiments, the selection rule is to select the minimum value, the middle value, or the maximum value in the liquid level height range.

[0831] It is understandable that different selection rules will affect the value of the correction parameter in the third step. For example, the correction parameter when selecting the minimum value in the liquid level height range will be greater than the correction coefficient when selecting the maximum value in the liquid level height range.

[0832] Second sub-step (2): determining a correction parameter according to the liquid level height and the inclination angle.

[0833] In some embodiments, the milk storage container portion is not shaped like a cylinder or a cuboid in which the difference in liquid level height and the difference in breast milk volume are linearly related. The linear relationship between the difference in liquid level height and the difference in breast milk volume means that the increase in breast milk volume from any height when the liquid level rises by a preset height is equal. For example, if the liquid level rises by 2 cm from 3 cm to 5 cm, the change in volume of breast milk stored in the milk storage container portion is equal to the change from the liquid level rising by 5 cm to 7 cm.

[0834] In some embodiments, as described above, the milk storage container portion is shaped such that the difference in liquid level height and the difference in breast milk volume are not linearly related, for example, in the shape of a bowl. If the shape is bowl-shaped, then the change in the volume of breast milk stored in the milk storage container portion when the liquid level height increases from 3 cm to 5 cm by 2 cm is smaller than the change in the volume of breast milk stored in the milk storage container portion when the liquid level height increases from 5 cm to 7 cm. This is because the higher the liquid level height, the larger the cross-sectional area of ​​the bowl, and the more breast milk can be stored.

[0835] Therefore, if the milk storage container is shaped such that the difference in liquid level height and the difference in breast milk volume are not linearly related, the liquid level height needs to be taken into account when calculating the correction parameter.

[0836] In some embodiments, when the volume of breast milk stored in the milk storage container is known, the milk storage container can be tilted to measure and record multiple sets of data. Then, by statistically analyzing the measured data and analyzing the patterns, a correspondence table between the liquid level, the tilt angle, and the correction parameter can be established. A correction parameter can be uniquely determined based on the liquid level and the tilt angle.

[0837] For example, the maximum storage volume of the milk storage container is defined as 150 mL, the maximum height of the liquid level is defined as 10 cm, and multiple measurement groups are established, each of which has a different actual volume of breast milk stored in the milk storage container.

[0838] For example, the actual volume of breast milk stored in the milk storage container portion of the first measurement group, i.e., the second volume, is 20 mL. The actual volume of the second measurement group is 25 mL, ..., and the actual volume of the twenty-first measurement group is 130 mL. The first measurement group is tilted to 5°, 10°, ..., 45°, 50°, ..., N°, where N is a positive integer greater than 50. The first volume and liquid level at each tilt angle are recorded. Then, a correction parameter is calculated based on the second volume and the first volume. At this time, the liquid level, tilt angle, and correction parameter at each tilt angle are recorded and entered into a correspondence table between liquid level height, tilt angle, and correction parameter. The same process is repeated for the remaining measurement groups and will not be repeated here. In this way, a correspondence table between liquid level height, tilt angle, and correction parameter is established.

[0839] In the above manner, the correction parameter may be the difference between the second volume and the first volume, or may be the proportional relationship between the second volume and the first volume.

[0840] Third sub-step (3): correcting the first volume according to the correction parameter to obtain a second volume of the breast milk stored in the milk storage container.

[0841] By correcting the first volume, an inclination angle can be introduced when calculating the breast milk volume, thereby improving the accuracy of the calculated second volume.

[0842] In some embodiments, after the third sub-step (3), the third step further includes a fourth sub-step (4).

[0843] Fourth sub-step (4): when the tilt angle is greater than a preset angle value, executing a preset operation.

[0844] In some embodiments, the preset operations include but are not limited to: stopping breast pumping and issuing a reminder message.

[0845] Among them, issuing reminder information includes but is not limited to controlling the alarm light to light up, controlling the buzzer to sound an alarm, issuing a voice prompt, issuing a warning message to the terminal communicating with the breast pump so that the APP running on the terminal pops up a warning window, etc.

[0846] If the tilt angle is too large, breast milk may overflow from the milk storage container, causing waste at best, or may flow back into the negative pressure mechanism 20 of the breast pump, causing damage to the negative pressure mechanism 20. Therefore, the present application performs a preset operation when the tilt angle is greater than a preset angle value, which can prevent breast milk from leaking, prevent waste, and protect the working safety of the breast pump.

[0847] In some embodiments, the third step includes: a fifth sub-step (5) and a sixth sub-step (6).

[0848] Fifth sub-step (5): obtaining a calculation formula; wherein the calculation formula is determined by the capacity and shape of the milk storage container.

[0849] In some embodiments, the calculation formula is established based on data obtained through prior measurements, and different calculation formulas may be used for milk storage containers of different capacities and shapes.

[0850] For example, the maximum storage volume of the milk storage container is defined as 150 mL, and the maximum liquid level is defined as 10 cm. Multiple measurement groups are established, and at least one of the actual volume of breast milk stored in the milk storage container, the tilt angle, and the liquid level is different in each measurement group.

[0851] For example, the actual volume of breast milk stored in the milk storage container portion in the first measurement group, ie, the second volume, is 20 mL, the actual volume of the second measurement group is 25 mL, ..., and the actual volume of the twenty-first measurement group is 130 mL.

[0852] The first measurement group is tilted to 5°, 10°, ..., 45°, 50° respectively, and the liquid level height at each tilt angle is recorded respectively to obtain multiple sets of data corresponding to the liquid level height, tilt angle and actual volume. The same is true for the remaining measurement groups and will not be repeated here.

[0853] Based on the obtained data of the multiple sets of liquid level heights, tilt angles and actual volumes, regression parameters are determined by a multiple linear regression method or a multiple nonlinear regression method to establish a regression line or a regression curve as a calculation formula corresponding to the milk storage container.

[0854] Exemplarily, the calculation formula is: volume = A*(liquid level height)+B*(inclination angle)+C; wherein A, B, and C are all regression parameters.

[0855] In some embodiments, milk storage container portions of different shapes and capacities correspond to different calculation formulas, that is, milk storage container portions of the same shape and different capacities correspond to different calculation formulas, and milk storage container portions of different shapes and the same capacity correspond to different calculation formulas, and milk storage container portions of different shapes and different capacities correspond to different calculation formulas.

[0856] Furthermore, the milk storage containers of different shapes and capacities mentioned above all correspond to different calculation formulas for milk storage containers in which the liquid level difference and the breast milk volume difference are not in a linear relationship.

[0857] It is understandable that if the liquid level difference in the milk storage container is linearly related to the volume difference of the breast milk, for example, if it is a regular cylinder, the calculation formula is the same, and there is no need to set multiple calculation formulas for milk storage containers of different capacities.

[0858] Sixth sub-step (6): determining the volume of breast milk stored in the milk storage container according to the liquid level, the tilt angle, and the calculation formula.

[0859] In some embodiments, the volume of breast milk stored in the milk storage container can be determined by entering the liquid level and the tilt angle into a calculation formula.

[0860] Please refer to Figure 51, which is a flow chart of a method for measuring breast milk volume using a breast pump according to an embodiment of the present application. As shown in Figure 51, the control method includes steps 4 to 7.

[0861] Step 4: Control the first measuring unit to measure the liquid level in the milk storage container.

[0862] For details, please refer to the introduction in the above part of the manual, which will not be repeated here.

[0863] Step 5: Control the second measuring unit to measure the tilt angle of the milk storage container.

[0864] For details, please refer to the introduction in the above part of the manual, which will not be repeated here.

[0865] Step 6: Control the second measuring unit to measure the tilt direction of the milk storage container.

[0866] In some embodiments, the second measuring unit is a three-axis acceleration sensor, and the second measuring unit is used to measure the three-axis acceleration of the milk storage container.

[0867] In some embodiments, the calculation formula of the tilt direction β is as follows:

[0868] Wherein, y is the y-axis acceleration measured by the three-axis acceleration sensor, and x is the x-axis acceleration measured by the three-axis acceleration sensor.

[0869] Step 7: Determine the volume of breast milk stored in the milk storage container according to the liquid level, the tilt angle, and the tilt direction.

[0870] In some embodiments, the milk storage container portion has an irregular shape, resulting in different liquid levels when the milk storage container portion is tilted in different directions at the same tilt angle when storing the same volume of breast milk.

[0871] Please refer to Figure 52, which is a schematic diagram of the structure of a milk storage container portion provided by an embodiment of the present application. As shown in Figure 52, when the milk storage container portion 50 is tilted in the first direction and the second direction, the same volume of breast milk will form different liquid levels. Therefore, when calculating the volume of breast milk stored in the milk storage container portion, the tilt direction of the milk storage container portion must also be considered.

[0872] In some embodiments, the seventh step includes the following steps.

[0873] (1) determining the region where the tilt direction is located in the first plane;

[0874] (2) determining a calculation formula according to the region where the tilt direction is located in the first plane;

[0875] (3) Determine the volume of breast milk stored in the milk storage container according to the liquid level, the tilt angle, and the calculation formula.

[0876] In some embodiments, the tilting direction refers to a tilting direction on a horizontal plane, and the tilting direction can be determined by a changing direction of an axis of the milk storage container portion.

[0877] Please refer to Figure 53, which is a schematic diagram of the region division provided in an embodiment of the present application. As shown in Figure 53, the horizontal plane is divided into four regions, each corresponding to a calculation formula. It is understood that the horizontal plane is divided into at least two regions, and the specific number of regions can be selected as needed and is not limited here.

[0878] In some embodiments, the calculation formula needs to be measured in advance. For example, a coordinate axis is established on the horizontal plane, and the inclination direction of the second area is defined to include [0°, 90°]. Then, after multiple measurements in the 45° direction, the calculation formula corresponding to the 45° direction is determined as the calculation formula for the entire second area.

[0879] The method for determining the calculation formula can be found in the introduction in the above part of the specification, which will not be repeated here.

[0880] In some implementations, the calculation accuracy of the calculation formula is proportional to the number of divided regions.

[0881] In some embodiments, the seventh step includes the following steps.

[0882] (1) determining the region where the tilt direction is located in the first plane;

[0883] (2) determining a corresponding relationship table according to the area where the tilt direction is located in the first plane;

[0884] (3) obtaining correction parameters by looking up the corresponding relationship table according to the liquid level and the tilt angle;

[0885] (4) determining a first volume of breast milk stored in the milk storage container portion based on the liquid level;

[0886] (5) Correcting the first volume according to the correction parameter to obtain a second volume of the breast milk stored in the milk storage container.

[0887] In some embodiments, each area within the first plane corresponds to a correspondence table; the correspondence table is used to store the correspondence between the liquid level height, the tilt angle and the correction parameter, and the corresponding correction parameter can be obtained by looking up the liquid level height and the tilt angle in the correspondence table.

[0888] In some embodiments, the correspondence table needs to be established in advance. For example, a coordinate axis is established on the horizontal plane, and the inclination direction of the second area is defined to include [0°, 90°]. Then, after multiple measurements in the 45° direction, the correspondence table measured in the 45° direction is determined as the correspondence table for the entire second area.

[0889] In the ninth embodiment.

[0890] 54 , an embodiment of the present invention provides a control method. In practical applications, the control method is applied in a breast pump control unit or in a terminal device connected to the breast pump, and includes steps 1 to 4.

[0891] The first step is to obtain in real time the current milk flow rate data information of the breast pump driven by the current milk pumping freque...
