Description

Technical Field

[0001] This utility model relates to the technical field of breast pumps, specifically a breast pump with real-time milk level monitoring. Background Technology

[0002] In the field of modern maternal and infant care, breast pumps have become an essential tool for many breastfeeding women. With the development of technology, wearable breast pumps have gradually gained popularity among users due to their convenience and discreetness. Traditional breast pumps are bulky and inconvenient to carry, and require the user to be in a relatively fixed position when using them, which brings many restrictions to the daily life and work of breastfeeding women. The emergence of wearable breast pumps has effectively solved these problems. They allow users to perform breast pumping while carrying out daily activities, greatly improving the flexibility of use.

[0003] However, existing wearable breast pumps have certain design limitations. Currently, when using wearable breast pumps, users usually hide the pump with clothing or other items to protect their privacy. While this approach satisfies users' privacy needs, it brings a serious problem: users cannot see the internal workings of the breast pump, and because the milk bowl is located below the breast pump, it is difficult for users to check the amount of milk in the bowl in real time during the pumping process.

[0004] Specifically, users cannot know the amount of milk in the feeding bowl in real time; during the pumping process, the milk volume will continue to increase, and if there is too much milk in the feeding bowl, it is easy to cause abnormal situations such as leakage or overflow; since the breast pump is hidden, these abnormal situations often cannot be confirmed and adjusted in real time while wearing it. Once leakage or overflow occurs, it will not only waste breast milk, but may also stain clothes, causing unnecessary trouble for users and seriously affecting the user experience.

[0005] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0006] The existing breast pumps mentioned above have technical problems, such as difficulty in monitoring the milk level in the bowl in real time during the pumping operation, which can easily lead to leakage, spillage, and other abnormal situations if there is too much milk in the bowl.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A breast pump with real-time milk level monitoring includes a main unit, a breast shield and a milk bowl connected to the main unit. The main unit is equipped with a negative pressure source capable of providing intermittent negative pressure and a control component capable of controlling the operating parameters of the negative pressure source. The milk bowl is located below the main unit. The bottom of the main unit is equipped with a visual sensing device electrically connected to the control component. The visual sensing device can monitor the liquid level in the milk bowl in real time and feed back the detected liquid level data to the control component to adjust the operating parameters of the negative pressure source.

[0009] As described above, in a breast pump for real-time monitoring of milk level, the visual sensing device includes at least one camera housing and a camera mounted on the corresponding camera housing. The camera is electrically connected to a control component, and the camera can transmit the collected image data to the control component.

[0010] As described above, in a breast pump for real-time monitoring of milk level, the camera housing includes an assembly column with an assembly cavity located at the bottom of the main unit, the assembly column extending upward, and the camera installed within the assembly cavity.

[0011] As described above, in a real-time milk level monitoring breast pump, the number of visual sensing devices is at least two, with the two visual sensing devices located on both sides of the milk pumping assembly to monitor the liquid level in the milk bowl.

[0012] Alternatively, the number of the visual sensing devices may be multiple, and the multiple visual sensing devices may be arranged in a ring array along the circumferential direction of the breast pumping assembly.

[0013] The breast pump described above, which monitors milk level in real time, further includes a light source emitting component located at the bottom of the main unit. The light source emitting component can project light from the top of the milk bowl into the milk bowl to illuminate the surface of the milk liquid inside the milk bowl.

[0014] As described above, in a real-time milk level monitoring breast pump, the light source emitting assembly includes at least one light source housing located at the bottom of the main unit and a light source component installed at the corresponding light source housing. The bottom of the light source housing can guide the light emitted by the light source component to be projected onto the top of the milk bowl.

[0015] As described above, in a real-time milk level monitoring breast pump, there are multiple visual sensing devices, and these multiple visual sensing devices are located near the edge of the milk bowl, while the multiple light source housings are located in the central area of ​​the milk bowl.

[0016] As described above, in a real-time milk level monitoring breast pump, the milk bowl is provided with a light-transmitting area inside the milk bowl, which is illuminated by a light source emitting component. The light-transmitting area is made of a transparent or semi-transparent material.

[0017] As described above, in a real-time milk level monitoring breast pump, the milk bowl is provided with an observation area for a visual sensing device to monitor the milk level inside the bowl, and the observation area is made of a transparent or semi-transparent material.

[0018] As described above, in a real-time milk level monitoring breast pump, the main unit is further provided with an alarm component electrically connected to the control component. The alarm component can trigger an alarm to alert the user that the amount of milk in the milk bowl is approaching or has reached its maximum capacity.

[0019] The beneficial effects of this utility model are as follows:

[0020] This utility model relates to a breast pump with real-time milk level monitoring, and pertains to the technical field of breast pumps. It includes a main unit, a breast shield, and a milk bowl. The main unit is equipped with a negative pressure source and a control component. The milk bowl is located below the main unit. A visual sensor electrically connected to the control component is located at the bottom of the main unit. The visual sensor monitors the liquid level in the milk bowl in real time, capturing the position information of the liquid surface and converting it into liquid level data. The visual sensor feeds back the detected liquid level data to the control component. The control component determines the milk volume in the milk bowl based on a preset program and the received liquid level data. When the milk bowl is nearly full, the breast pump automatically stops pumping or adjusts the pumping parameters to prevent milk overflow, waste, and contamination, maintaining a clean usage environment. The visual sensor allows users to know the status of the milk bowl in a timely manner, improving convenience and comfort.

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] like Figures 1 to 7 As shown, this embodiment of a breast pump with real-time milk level monitoring includes a main unit 1, a breast shield 2 and a milk bowl 3 connected to the main unit 1. The main unit 1 is equipped with a negative pressure source capable of providing intermittent negative pressure and a control component 5 capable of controlling the operating parameters of the negative pressure source. The milk bowl 3 is located below the main unit 1. The control component in the main unit activates the negative pressure source, which generates intermittent negative pressure and transmits it to the breast shield. The breast shield fits against the breast. Under the action of negative pressure, the breast shield 2 simulates the sucking action of an infant, drawing milk from the breast. The drawn milk flows along the milk suction component into the milk bowl located below the main unit.

[0031] Specifically, the bottom of the main unit 1 is equipped with a visual sensing device 6 electrically connected to the control component 5. The visual sensing device at the bottom of the main unit monitors the liquid level in the milk bowl in real time. The visual sensing device uses image recognition and other technologies to capture the position information of the liquid surface in the milk bowl and convert it into liquid level data.

[0032] The visual sensing device feeds back the detected liquid level data to the control component, which then determines the amount of milk in the milk bowl based on the preset program and the received liquid level data.

[0033] If the liquid level approaches or reaches the maximum capacity of the milk bowl, the control components will adjust the operating parameters of the negative pressure source; for example, reducing the negative pressure intensity of the negative pressure source to reduce the amount of milk sucked in; or changing the intermittent frequency of the negative pressure to slow down the milk pumping process; if the liquid level reaches a dangerous value, the control components will directly stop the negative pressure source from working, stopping the milk pumping mode of the breast pump.

[0034] Preferably, the host 1 in this embodiment is also provided with a warning component electrically connected to the control component 5. The warning component can trigger an alarm prompt, and the alarm method can be sound alarm, light flashing, etc., to prompt the user that the amount of milk in the milk bowl 3 is close to or has reached the maximum capacity.

[0035] When the milk bowl is almost full, the breast pump can automatically stop pumping or adjust the pumping parameters to prevent milk from overflowing, causing waste and contamination, and to keep the usage environment clean.

[0036] For users of breast pumps, there is no need to constantly monitor the amount of milk in the bottle, reducing the burden on users. The visual sensor allows users to know the status of the bottle in a timely manner, making it convenient for users to handle the situation promptly, thus improving the convenience and comfort of use.

[0037] Adjusting the working parameters of the negative pressure source according to the liquid level in the milk bowl can make the breast pumping process more scientific and reasonable. For example, when the milk bowl is almost full, the negative pressure intensity can be appropriately reduced, which can not only prevent milk from spilling out, but also reduce excessive stimulation to the breast to a certain extent and protect breast health.

[0038] like Figures 1 to 7 As shown, the visual sensing device 6 of this embodiment includes at least one camera housing 61 and a camera 62 installed in the corresponding camera housing 61.

[0039] Specifically, the camera 62 is installed at the camera housing 61, which provides a stable installation position and a suitable viewing angle for the camera. The camera continuously collects images of the situation inside the milk bowl 3, capturing real-time image information of the liquid surface inside the milk bowl.

[0040] Specifically, the acquired image data is transmitted to the control component 5. The control component usually has a dedicated image recognition algorithm and processing program to analyze the transmitted images. By identifying features such as the position and height of the liquid surface in the image, it is converted into specific liquid level data. For example, image processing technology is used to determine the pixel position of the liquid surface in the image, and then combined with parameters such as the relative position of the camera and the milk bowl, the actual liquid height in the milk bowl is calculated.

[0041] Furthermore, the control component determines the amount of milk in the milk bowl based on the processed liquid level data. If the liquid level is close to or reaches the maximum capacity of the milk bowl, the control component will adjust the working parameters of the negative pressure source according to the preset logic, such as reducing the negative pressure intensity, changing the negative pressure intermittent frequency, or stopping the negative pressure source from working. It may also trigger an alarm.

[0042] Specifically, the camera can capture images of the liquid level inside the milk bowl in real time, which can more intuitively and accurately reflect the actual liquid level inside the milk bowl. It can accurately identify minute changes in the liquid level, promptly detect the growth trend of milk volume, and provide accurate liquid level data for the control components, thereby achieving more precise control of the breast pump.

[0043] The camera-based visual sensing method is highly adaptable to different shapes and sizes of milk bowls. As long as the camera's installation position and viewing angle are adjusted, liquid level monitoring can be performed on various milk bowls without the need to design specific liquid level monitoring devices for different sizes of milk bowls.

[0044] Preferably, the image data collected by the camera can be used for other extended applications besides monitoring the liquid level. For example, it can be used to analyze the color and clarity of the milk, providing users with more information about the quality of the milk.

[0045] Furthermore, the camera obtains liquid level information by capturing images, without needing to come into direct contact with the breast milk. This avoids hygiene problems caused by contact with breast milk, reduces the risk of bacterial growth and cross-contamination, and ensures hygiene and safety during the use of the breast pump.

[0046] like Figures 1 to 7 As shown, the camera housing 61 in this embodiment includes an assembly post with an assembly cavity located at the bottom of the host 1. The assembly post extends upward, and the camera 62 is installed in the assembly cavity.

[0047] Specifically, the mounting column serves as the camera housing, providing a precise mounting position for the camera 62. The camera 62 is installed inside the mounting column at the bottom of the main unit 1. Through the structural design of the mounting column, it is ensured that the camera can be firmly fixed in a specific position, ensuring that it will not shake or shift during the operation of the breast pump, thereby maintaining a stable image acquisition angle.

[0048] Preferably, the mounting column position at the bottom of the main unit 1 is designed so that the camera 62 installed therein can obtain a suitable angle to observe the liquid level in the milk bowl. The camera captures images of the liquid surface in the milk bowl from this fixed angle, and the captured images include information such as the height and shape of the liquid surface.

[0049] After the camera 62 acquires image data, it transmits the data to the control component 5 of the host 1 through internal circuitry. The control component processes and analyzes the image data, calculates the liquid level in the milk bowl based on the characteristics of the liquid surface in the image, and then adjusts the working status of the breast pump according to the liquid level.

[0050] The design of the assembly column makes the camera installation process relatively simple. The basic installation can be completed simply by accurately placing the camera into the assembly cavity of the assembly column. There is no need for complicated installation steps and additional fixing devices, which improves the efficiency of production and assembly.

[0051] The mounting column can precisely determine the position and angle of the camera, ensuring that the camera is always aimed at the liquid surface in the milk bowl from the best angle. This ensures that the collected images can accurately reflect the liquid level in the milk bowl, improving the accuracy and reliability of liquid level monitoring.

[0052] Installing the camera in the mounting post at the bottom of the main unit 1 can provide some protection for the camera. The mounting post can prevent external objects from directly colliding with the camera, reduce damage to the camera caused by collisions, friction and other reasons, and extend the life of the camera.

[0053] From an aesthetic perspective, concealing the camera within the mounting column at the bottom of the main unit makes the overall design of the breast pump more streamlined and aesthetically pleasing. This avoids the camera being exposed and negatively impacting the product's overall visual appeal, thus enhancing its appearance and quality.

[0054] If the camera malfunctions or requires cleaning, replacement, or other maintenance, the mounting holes allow for easy disassembly and installation, reducing the difficulty and cost of maintenance.

[0055] like Figures 1 to 7 As shown, the number of visual sensing devices 6 in this embodiment is at least two, and the two visual sensing devices 6 are respectively located on both sides of the milk suction assembly 4 to monitor the liquid level in the milk bowl 3.

[0056] Alternatively, there may be multiple visual sensing devices 6, and these multiple visual sensing devices 6 may be arranged in a ring array along the circumferential direction of the breast pump assembly 4. Preferably, two or more camera housings 61 may be arranged on each side of the breast pump assembly 4. In this way, even when the user is in a lying position and the breast pump is tilted, the liquid level in the milk bowl can be accurately identified.

[0057] When two, two, or more cameras are installed on each side of the breast pump assembly 4 in multiple camera housings 61, each camera will capture images of the liquid level in the milk bowl from different angles. When the breast pump is used upright normally, the images captured by multiple cameras can complement and verify each other, providing a more comprehensive and accurate reflection of the liquid level information in the milk bowl.

[0058] When the user is lying down and the breast pump is tilted, the liquid level in the milk bowl will also tilt. At this time, the images of the liquid level captured by cameras at different positions will differ due to their different viewing angles. For example, the liquid level seen by a camera on the higher side will be different from that seen by a camera on the lower side. After receiving the images from each camera, the control component fuses and analyzes these images. Using image processing algorithms, combining image information from multiple cameras at different perspectives, it reconstructs the three-dimensional shape of the liquid level in the milk bowl, thereby accurately calculating the actual liquid level height and volume. By comparing the characteristics and positional relationships of the liquid level in the images from different cameras, the control component can determine the tilt state of the breast pump and correct the liquid level calculation results to eliminate the influence of tilt on liquid level recognition.

[0059] When the breast pump is tilted, multiple cameras monitor from different angles, providing richer image information and effectively avoiding misjudgments of the liquid level caused by tilting. Regardless of the tilt angle of the breast pump, the coordinated work of multiple cameras can accurately identify the liquid level in the milk bowl, ensuring that the breast pump can be accurately controlled according to the actual liquid level, such as stopping pumping in time or adjusting the pumping parameters.

[0060] The above design allows users to use the breast pump in a lying position, greatly improving the user experience. Users can choose a more comfortable position during the pumping process, without having to maintain an upright sitting posture, reducing physical fatigue. This is especially convenient and comfortable for postpartum women who are relatively weak, as the lying position helps to improve the efficiency and effectiveness of pumping.

[0061] This design allows the breast pump to adapt to different usage scenarios and postures, expanding the product's applicability. Whether used lying down at home or tilted in other special circumstances, it ensures accurate liquid level recognition and normal operation of the breast pump, enhancing the product's reliability and practicality and meeting diverse user needs.

[0062] Preferably, multiple visual sensing devices are arranged in a ring array along the circumferential direction of the milk suction assembly 4, which can simultaneously acquire images inside the milk bowl 3 from multiple different angles. Each visual sensing device is responsible for acquiring image information of the milk bowl within its own angle range.

[0063] After receiving images from multiple visual sensors, the host system performs comprehensive analysis on these images. By fusing image information from multiple perspectives, the system can construct a three-dimensional model of the milk in the milk bowl. In this three-dimensional model, the position and height of the liquid level can be determined more accurately. For example, when the milk is unevenly distributed in the milk bowl, the liquid level information collected by visual sensors at different locations will be different. The system can analyze and correct these differences to obtain accurate liquid level data.

[0064] Furthermore, having two visual sensors on either side or multiple visual sensors arranged in a circular array can effectively reduce blind spots in the milk bowl. Visual sensors in different positions can provide image information from multiple perspectives. By comprehensively analyzing this information, errors caused by a single perspective can be eliminated. For example, when there are fluctuations or reflections on the surface of the milk, images from different perspectives can complement and verify each other, enabling the system to more accurately determine the liquid level.

[0065] The design of multiple vision sensors provides redundancy. If one vision sensor fails or is damaged, the others can still continue to work, ensuring normal liquid level monitoring. This improves the reliability and stability of the entire system and reduces monitoring interruptions or errors caused by equipment failure.

[0066] Furthermore, image data collected by multiple visual sensing devices can be cross-verified. When there are differences in the liquid level data received by the system from different devices, the accuracy of the data can be judged through further analysis and comparison, thereby improving the reliability of the monitoring results.

[0067] During breast pumping, the flow and distribution of milk can be quite complex, such as splashing or tilting. Multiple visual sensors can better handle these complex conditions and accurately capture the actual liquid level of the milk through monitoring from multiple perspectives.

[0068] Different milk bowls may have different shapes and sizes. The design of multiple vision sensors can better adapt to milk bowls of various shapes, and can achieve accurate liquid level monitoring, whether the milk bowl is round, square or other irregular shapes.

[0069] like Figures 1 to 7 As shown, the breast pump in this embodiment also includes a light source emitting component 7 located at the bottom of the main unit 1. The light source emitting component 7 can project light from the top of the milk bowl 3 into the milk bowl 3. The light source emitting component 7 continuously illuminates the liquid level in the milk bowl, making the visual sensing device 6 receive the light more accurately.

[0070] Specifically, the light source emitting component 7 is installed at the bottom of the main unit 1. It can project light from the top of the milk bowl 3 into the inside of the milk bowl. When the light shines on the liquid surface inside the milk bowl 3, a reflection phenomenon occurs. The reflection of light on the liquid surface follows the law of reflection, and the reflected light will propagate out at a specific angle.

[0071] The visual sensing device 6 is designed to receive information carried by reflected light. Factors such as the height and shape of the liquid surface will affect the propagation path and intensity distribution of the reflected light. For example, when the liquid level rises or falls, the angle and intensity of the reflected light reaching the visual sensing device 6 will change. Fluctuations in the liquid surface will also cause different scattering of the reflected light. The visual sensing device 6 detects these characteristic changes in the reflected light, converts them into electrical or digital signals, and then transmits them to the control components of the breast pump.

[0072] After receiving the signal from the visual sensing device 6, the control component will use a preset algorithm to analyze and process these signals. By analyzing the changes in the characteristics of reflected light, the control component can infer information such as the position, height, and fluctuation of the liquid surface in the milk bowl 3, thereby achieving accurate identification of the liquid level in the milk bowl.

[0073] Under natural light conditions, the intensity and direction of light may be unstable, and the ambient light around the milk bowl may interfere with the detection of the visual sensing device 6, resulting in inaccurate liquid level recognition. The light source emitting component 7 continuously projects light into the milk bowl, providing stable and uniform lighting conditions. This reduces the influence of ambient light, enabling the visual sensing device 6 to capture the light information reflected from the liquid surface more clearly and accurately, thereby improving the accuracy of liquid level recognition.

[0074] The use environment of a breast pump can be varied, including dimly lit indoor environments or places with different light intensities. The setting of the light source emission component 7 enables the breast pump to work normally under various ambient light conditions. Even in the case of insufficient light, it can provide enough light for the visual sensing device 6 to ensure that the liquid level recognition function is not limited by ambient light, thereby enhancing the adaptability and reliability of the breast pump in different environments.

[0075] Specifically, accurate liquid level recognition is crucial for the normal operation of a breast pump. If the liquid level recognition is inaccurate, the breast pump may continue to work even when the milk bowl is full, causing milk to overflow; or it may stop working prematurely when there is still a lot of milk in the milk bowl, affecting the milk pumping efficiency. The light source emitting component 7 helps to improve the accuracy of liquid level recognition, thereby ensuring that the breast pump can make reasonable control according to the actual liquid level in the milk bowl, avoiding the above problems, and ensuring the normal operation and effectiveness of the breast pump.

[0076] like Figures 1 to 7 As shown, the light source emitting assembly 7 of this embodiment includes at least one light source accommodating part 71 disposed at the bottom of the host 1 and a light source element 72 installed at the corresponding light source accommodating part 71. The bottom of the light source accommodating part 71 can guide the light emitted by the light source element 72 to be projected onto the top of the milk bowl 3.

[0077] Preferably, the light source 72 is typically a device capable of converting electrical energy into light energy, such as a common light-emitting diode (LED) or organic light-emitting diode (OLED). When current passes through the light source 72, electrons and holes inside recombine, releasing energy and emitting light in the form of photons. Different types of light sources 72 may have different light-emitting characteristics, such as emission color and emission intensity.

[0078] The light source housing 71 provides a mounting and fixing position for the light source component 72. It can protect the light source component 72 from external impacts, dust, and moisture, ensuring that the light source component 72 can work stably. At the same time, the light source housing 71 can also guide and constrain the light emitted by the light source component 72. For example, it can be designed into a specific shape so that the light can be projected into the milk bowl 3 in a predetermined direction and angle, improving the utilization efficiency of the light. Preferably, the light source housing 71 in this embodiment adopts an assembly hole structure, but it can also adopt an assembly column structure with an assembly cavity, etc. The appropriate design can be selected according to actual needs.

[0079] Specifically, after the light source 72 installed in the light source housing 71 emits light, the light will be projected from the bottom of the main unit 1 to the top of the milk bowl 3. During the propagation process, the light will hit the liquid surface in the milk bowl 3 and then be reflected. The reflected light is received by the visual sensing device 6. The visual sensing device 6 converts the light information into an electrical signal or a digital signal and transmits it to the control component of the breast pump for analysis and processing, thereby realizing the monitoring of the liquid level in the milk bowl.

[0080] The light source housing 71 provides a relatively enclosed and stable environment for the light source component 72. During the use of the breast pump, it may be affected by various external factors, such as vibration, dust, and moisture. The light source housing 71 can effectively block these external factors from damaging the light source component 72, extend the service life of the light source component 72, reduce the probability of damage to the light source component 72, and thus improve the reliability and stability of the breast pump.

[0081] The light source housing 71 provides a standardized mounting position for the light source component 72, making its installation more convenient and accurate. This improves assembly efficiency and reduces production costs during manufacturing. In later maintenance, if the light source component 72 malfunctions, it can simply be removed from the light source housing 71 for replacement, eliminating the need for extensive disassembly and repair of the entire breast pump, thus improving maintenance convenience and efficiency.

[0082] The light source component 72 is installed in the light source housing 71, forming a relatively independent light source emitting assembly 7. This modular design makes the structure of the breast pump clearer and facilitates product upgrades and improvements. For example, if it is necessary to replace the light source component 72 with a different type or performance, only the light source emitting assembly 7 needs to be adjusted accordingly without affecting other parts of the breast pump. At the same time, the modular design is also beneficial for mass production and quality control.

[0083] like Figures 1 to 7As shown, in this embodiment, there are multiple visual sensing devices 6, and the multiple visual sensing devices 6 are located near the edge of the milk bowl 3, while the multiple light source housings 71 are located in the central area of ​​the milk bowl 3.

[0084] Specifically, multiple visual sensing devices 6 are located near the edge of the milk bowl 3. They can acquire images of the inside of the milk bowl from different angles around the edge. Because they are located at the edge, each visual sensing device can obtain image information of the milk in the milk bowl from different perspectives. After receiving these image signals, the host system uses image processing algorithms to identify information such as the liquid level and distribution of the milk based on the differences in color, grayscale, texture and other features of the milk and air in the image.

[0085] Multiple light source housings 71 are located in the central area of ​​the milk bowl 3. Light source housings generally contain light-emitting elements, such as LED lights. These light sources emit light from the central area of ​​the milk bowl to the surrounding areas, evenly illuminating the inside of the milk bowl. When the light shines on the surface of the milk, reflection and refraction occur. The reflected light is captured by the visual sensing device at the edge. Appropriate lighting conditions can enhance the contrast between the milk and the surrounding environment in the image, making the image collected by the visual sensing device clearer and facilitating the subsequent image processing system to accurately identify relevant information about the milk.

[0086] The central light source housing provides uniform illumination to the inside of the milk bowl. Compared to placing the light source at the edge or other locations, the light radiating from the center outwards avoids shadow areas and illuminates every corner of the milk bowl. This helps the visual sensing device capture images with high contrast and clarity, reducing problems such as image blurring and distortion caused by uneven lighting, thereby improving the accuracy of liquid level monitoring and milk condition recognition.

[0087] Good lighting conditions can highlight the characteristics of milk. For example, under clear light, details such as the tiny ripples on the surface of the milk and the boundary between the milk and the bowl wall can be presented more clearly. Visual sensing devices can capture these features more accurately, and the host system can more accurately identify the liquid level and the distribution of milk when performing image processing.

[0088] Multiple visual sensors located at the edge can monitor the milk bowl from different angles, forming a comprehensive monitoring network. Compared with a single visual sensor or a small number of visual sensors, it can cover a larger area inside the milk bowl, reduce blind spots, and even if the milk is unevenly distributed inside the milk bowl, or if there is splashing or tilting, multiple visual sensors can still capture the true state of the milk from different perspectives, ensuring comprehensive acquisition of milk information.

[0089] Preferably, this separate layout ensures that the visual sensing device and the light source work normally, improving the stability and reliability of the entire monitoring system.

[0090] This design is adapted to the structure of the milk bowl. The central area of ​​the milk bowl is relatively open, which is suitable for placing the light source; while there is enough space at the edge to install multiple visual sensing devices without hindering the normal use of the milk bowl and the collection of milk. It also facilitates the installation and maintenance of the devices.

[0091] like Figures 1 to 7 As shown, the top of the milk bowl 3 in this embodiment is provided with an upwardly extending connecting protrusion 31, and the top of the milk bowl 3 is in a shape that gradually slopes upward along the outer side of the milk bowl 3 towards the connecting protrusion 31.

[0092] Specifically, as the liquid level rises, the milk first fills the bottom and lower areas of the milk bowl. When the visual sensor 6 detects that the liquid level is close to or reaches the maximum capacity of the milk bowl (this maximum capacity may be set based on the volume of the bottom and most of the main body area of ​​the milk bowl), the tilted top is not actually completely occupied by the milk, thus reserving some space inside the milk bowl.

[0093] When the user disassembles the milk bowl 3, the milk will be affected by gravity and inertia. If the top of the milk bowl is flat and the milk is just full, the milk will easily overflow during disassembly, even with slight shaking or tilting. The design of the tilted top and the connecting protrusion 31 makes the milk flow on the tilted surface and be blocked by the connecting protrusion 31 when it is subjected to external force, so that it will not overflow directly from the edge of the milk bowl. This uses the principle of mechanics to prevent the milk from overflowing.

[0094] Preventing milk spillage means that users don't have to worry about making a mess of the surrounding environment, such as tabletops or floors, when disassembling the milk bowl, reducing the hassle of cleaning up spilled milk later and making the process more convenient and comfortable.

[0095] Preferably, the connecting protrusion 31 serves as a connection interface, facilitating connection with other components (such as the main unit 1, the breast pump assembly 4, etc.), such as screw connection or snap-fit ​​connection, and a suitable design can be selected according to actual needs.

[0096] like Figures 1 to 7 As shown, in this embodiment, the top of the milk bowl 3 is close to or touches the bottom of the host 1, and the distance between the two is controlled within a small range. This reduces the interference of external light. Because the close distance allows the visual sensing device 6 to form a relatively closed optical environment with the liquid surface inside the milk bowl, in this relatively stable environment, the light emitted by the visual sensing device 6 (such as infrared light or visible light) can be more directly irradiated onto the liquid surface inside the milk bowl, and the reflected light can also be received by the sensing device more effectively, thereby forming a clear and accurate liquid surface image.

[0097] Because of the close distance, the path of light propagation is relatively short, and the light is less affected by factors such as air refraction and scattering during propagation, which can minimize image distortion. This makes the liquid surface image acquired by the visual sensing device 6 closer to the real situation, providing a reliable basis for subsequent accurate analysis of information such as liquid level height.

[0098] By acquiring a more intuitive and accurate real-time image of the liquid level inside the milk bowl, the visual sensing device 6 can accurately determine the height of the milk level.

[0099] A clear and accurate image can reduce the probability of misjudging the liquid level by the visual sensor 6. For example, in poor lighting conditions or when the liquid level is fluctuating, if the top of the milk bowl is far from the bottom of the main unit, misjudgments of the liquid level may occur. This design can effectively avoid such problems and improve the reliability of the system.

[0100] like Figures 1 to 7 As shown, the milk bowl 3 in this embodiment is provided with a light-transmitting area for the light source projected by the light source emitting component 7 to illuminate the inside of the milk bowl 3. The light-transmitting area is made of a transparent or semi-transparent material. The light emitted by the light source emitting component 7 enters the inside of the milk bowl 3 through the light-transmitting area. The transparent or semi-transparent material has good light transmittance. When light shines on the light-transmitting area, most of the light can pass through the area and continue to propagate inside the milk bowl according to the principle of rectilinear propagation of light. If it is a transparent material, the light can pass through almost without obstruction, ensuring that the intensity and direction of light propagation remain basically unchanged; if it is a semi-transparent material, the light will be scattered to a certain extent, but it can still enter the inside of the milk bowl, so that the inside of the milk bowl receives relatively uniform illumination.

[0101] The design of the light-transmitting area allows light from the light-emitting component to effectively enter the milk bowl, avoiding the problem of light not being able to enter due to the opaque material of the milk bowl. Transparent or semi-transparent materials can distribute light evenly inside the milk bowl, reduce shadow areas, provide good lighting conditions for the visual sensing device, help to obtain clear and accurate image information, and improve the accuracy of monitoring the milk level and status.

[0102] Compared to setting up complex light-guiding structures (such as light guides) on the milk bowl, using transparent or semi-transparent light-transmitting areas results in less light loss during propagation. This allows for full utilization of the light emitted by the light source emitting components, improving energy efficiency, while also ensuring sufficient light intensity inside the milk bowl so that the visual sensing device can clearly capture the characteristics of the milk.

[0103] like Figures 1 to 7As shown, the milk bowl 3 in this embodiment is provided with an observation area for the visual sensing device 6 to monitor the milk level in the milk bowl 3. The observation area is made of a transparent or semi-transparent material.

[0104] Because the observation area is made of transparent or semi-transparent material, light can pass through the area and enter the inside of the milk bowl. When the light shines on the surface of the milk, it will be reflected. The reflected light will then pass through the observation area and be emitted. The visual sensing device is located in a suitable position and can capture these reflected lights.

[0105] After receiving reflected light, the visual sensing device converts it into an electrical or digital signal and transmits it to the connected host system.

[0106] A transparent or semi-transparent observation area can provide a clear field of view for the visual sensing device, reduce light scattering and refraction interference, and enable the reflected light to accurately transmit information about the milk level. This makes the image captured by the visual sensing device clearer and more accurate, and the host system can more accurately identify the liquid level line, thereby improving the accuracy of liquid level monitoring.

[0107] This design works well under different lighting conditions. In a bright natural light environment, the transparent or semi-transparent material allows enough light to enter the milk bowl, ensuring normal liquid level monitoring. In a dimly lit environment, an auxiliary light source can be set up to provide good lighting conditions for the visual sensing device by utilizing the light transmittance of the observation area, ensuring that liquid level monitoring is not affected by ambient light.

[0108] Preferably, the milk bowl 3 can be made of a transparent material, that is, both the light-transmitting area and the observation area are the outer wall of the milk bowl 3; or, the observation area is an observation window on the milk bowl 3 corresponding to the visual sensing device 6; or, the light-transmitting area is a light-transmitting window on the milk bowl 3 corresponding to the light source emitting component 7, and a suitable design can be selected according to actual needs.

[0109] Preferably, the breast pump further includes a breast pumping assembly 4 disposed between the main unit 1 and the breast shield 2. The breast pumping assembly 4 includes a breast pumping channel 41, a negative pressure chamber 42, and a one-way valve 43. The breast pumping channel 41 is sealed and connected to the negative pressure chamber 42. The one-way valve 43 is located at the bottom of the breast pumping channel 41. The negative pressure source is connected to the negative pressure chamber 42. The negative pressure source generates negative pressure in the negative pressure chamber, thereby drawing milk from the breast through the breast pumping channel (e.g., by deforming the breast pumping channel; or by setting a deformable part on the outside of the breast pumping channel, etc., a suitable design can be selected according to actual needs). The one-way valve ensures that the milk can only flow in one direction and prevents the milk from flowing back.

[0110] Preferably, the negative pressure source includes an air pump and connecting air pipes connected to the air pump and the negative pressure chamber respectively.

[0111] Preferably, the control component 5 includes a control motherboard located inside the host 1 and control components (such as buttons, knobs, or touch screens) located outside the host 1.

Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
