[0027] This utility model proposes a breast shield 100.

[0028] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the breast pump shield 100 has a breast pumping channel 1, and the breast pumping channel 1 is provided with a blocking member 2, and the blocking member 2 has a plurality of liquid passage holes 21 for milk to pass through.

[0029] In this utility model, the blocking member 2 is disposed within the breast pumping channel 1. Its main function is to reduce the stretching and swelling of the nipple under suction. The liquid passage holes 21 are multiple small holes on the blocking member 2, allowing milk to pass through while preventing excessive stretching of the nipple. The design of multiple liquid passage holes 21 helps to disperse the suction force and reduce the pressure on the nipple. Through the design of the blocking member 2 and the liquid passage holes 21, the direct suction force on the nipple during the breast pumping process can be reduced, lowering the risk of nipple discomfort and swelling, and improving the user's breast pumping experience. This breast pumping shield 100 can not only be used in breast pumps, but can also be integrated into bras with breast pumping function. This utility model does not limit this. The liquid passage holes 21 can be circular or elliptical. This utility model does not limit this, and the number of liquid passage holes 21 in this embodiment is also not limited.

[0030] To improve the ease of use of the breast shield 100, in one embodiment of this utility model, the blocking member 2 is detachably connected to the inner peripheral wall of the breast suction channel 1. The connection between the blocking member 2 and the inner peripheral wall of the breast pumping channel 1 is detachable, allowing for easy assembly and separation of the blocking member 2 and the inner peripheral wall of the breast pumping channel 1. The detachable design makes it easier to replace or clean the blocking member 2 when needed, helping to maintain the hygiene and function of the breast pump shield 100. If the blocking member 2 is damaged or worn, it can be replaced individually without replacing the entire breast pump shield 100, reducing maintenance costs and extending the overall service life of the breast pump shield 100. The detachable connection allows users to thoroughly clean the breast pump shield 100 and the blocking member 2 after each use, reducing the risk of bacterial growth and cross-infection. The detachable design also allows users to adjust the position of the blocking member 2 or replace it with a different size blocking member 2 according to personal needs or comfort. The detachable connection between the blocking member 2 and the breast pumping channel 1 can be achieved by providing threaded structures on both the inner peripheral wall of the breast pumping channel 1 and the outer peripheral wall of the blocking member 2, or by providing a groove on the inner peripheral wall of the breast pumping channel 1 and a buckle on the outer peripheral wall of the blocking member 2; this invention does not limit this approach.

[0031] In one embodiment of this utility model, the blocking member 2 is integrally formed with the inner peripheral wall of the breast pumping channel 1. The blocking member 2 and the inner peripheral wall of the breast pumping channel 1 are directly connected by an integral forming process to form a continuous, seamless structure. Integral forming reduces additional assembly steps, simplifies the production process, and improves manufacturing efficiency. Since the blocking member 2 and the inner peripheral wall of the breast pumping channel 1 are integrally formed, the entire structure is more stable, reducing the possibility of loosening or deformation during use. Integral forming reduces material waste caused by assembling multiple parts and is generally more durable than assembled structures.

[0032] To further protect the nipple, in one embodiment of this invention, the blocking member 2 is made of a flexible material. Using a flexible material allows for better adaptation to different nipple shapes and sizes, providing a more comfortable fit; the flexible material also gives the blocking member 2 a certain degree of elasticity, allowing it to adapt to different suction and pressure changes without damaging the nipple; the flexible material reduces friction between the nipple and the blocking member 2, improving comfort during breastfeeding; furthermore, the flexible material better conforms to the breast, forming an effective seal to prevent air leakage, improving breastfeeding efficiency, helping to disperse suction force, and reducing nipple stretching and swelling during breastfeeding, thereby alleviating swelling and discomfort; the flexible material can be silicone or polypropylene, and this invention does not limit this choice.

[0033] To prevent the blocking member 2 from breaking and affecting the breast pumping operation, in one embodiment of this utility model, the blocking member 2 includes multiple hollow layers stacked sequentially along the extension direction of the breast pumping channel 1, and each hollow layer forms multiple liquid passage holes 21. By designing the blocking member 2 as a structure of multiple hollow layers stacked together, there can be an appropriate spacing between two adjacent hollow layers to distribute the force and reduce the risk of single-layer material breaking due to concentrated force; the multi-layer structure provides better overall stability, and even if one layer suffers minor damage, the other layers can still maintain the integrity of the blocking member 2; the hollow layer design reduces the suction area in direct contact between the nipple and the blocking member 2, thereby reducing the pressure and discomfort caused by direct suction on the nipple.

[0034] In one embodiment, the blocking member 2 can be made of a single material that possesses both soft and hard properties. For example, a composite material can be used, with a soft silicone surface and a polypropylene material with a certain degree of hardness inside. This design ensures both comfort when in contact with the nipple and provides sufficient structural strength to distribute suction. The blocking member 2 can also be composed of multiple layers of materials, where the layer closest to the nipple is a soft material (such as silicone), and the layer furthest from the nipple is a hard material (such as polypropylene). This layered design can be optimized according to the shape of the nipple and the distribution of suction to provide better fit and support. In the multi-layer material structure, the layer closest to the nipple is the softest material, and the hardness of the material gradually increases with the direction away from the nipple. For example, the innermost layer is soft silicone, the middle layer is a harder polypropylene, and the outermost layer is a harder plastic material. This design can better support the nipple, prevent the nipple from being overstretched under suction, and provide sufficient structural stability. Through a combination of soft and hard materials, the blocking element 2 can better support the nipple, reducing the stretching and swelling of the nipple under suction. Especially in the multi-layer material structure, the design with gradually changing hardness can more effectively disperse the suction force and reduce the pressure on the nipple. The soft inner material can better conform to the shape of the nipple, reducing friction and pressure, while the hard outer material provides sufficient structural strength to prevent the nipple from being overstretched under suction. This design significantly reduces the risk of nipple swelling and discomfort. The use of flexible materials (such as silicone) can reduce friction between the nipple and the blocking element 2, improving comfort during breast pumping. At the same time, the multi-layer material design can be adjusted according to the nipple shape and suction needs of different users, providing a personalized and comfortable experience.

[0035] Please see Figure 2 In one embodiment of this invention, at least some of the liquid passage holes 21 have different aperture sizes. Different aperture sizes of the liquid passage holes 21 help to evenly distribute suction in localized areas, reducing localized high-pressure areas on the nipple, thereby reducing the risk of nipple discomfort and damage. The evenly distributed pressure also protects the nipple from excessive stretching or compression. By using different sized liquid passage holes 21, the speed and direction of milk flow can be adjusted, allowing milk to pass more smoothly through the milk suction channel 1, reducing the risk of blockage. Different aperture sizes provide an optimized fluid dynamics design, thereby improving milk extraction efficiency and making the milk suction process more efficient.

[0036] To improve the flow efficiency of milk, in one embodiment of this invention, the inner peripheral wall of the liquid passage 21 is formed with a flow-guiding slope. In the extending direction of the liquid passage 21, the cross-sectional area of ​​the flow-guiding slope gradually decreases from the inlet end to the outlet end of the liquid passage 21. The flow-guiding slope on the inner peripheral wall of the liquid passage 21 helps guide fluid (such as milk) to flow more smoothly through the liquid passage 21. The gradual decrease in cross-sectional area from the inlet end to the outlet end of the flow-guiding slope helps accelerate fluid flow and reduce turbulence and eddies. The flow-guiding slope and the gradually decreasing cross-sectional area design help improve the efficiency of fluid passage through the liquid passage 21, reduce fluid resistance, and also help reduce milk retention within the liquid passage 21, facilitating cleaning and maintenance.

[0037] Please see Figure 2 In one embodiment of the present invention, the breast shield 100 is formed with a flange soft part 3 communicating with the breast suction channel 1, and the cross-sectional area of ​​the blocking member 2 gradually decreases from the end near the flange soft part 3 to the end away from the flange soft part 3. The flange soft part 3 is part of the breast shield 100 and is typically made of soft material. It is used to contact the skin of the breast, providing a comfortable seal and fit. The blocking member 2 gradually decreases in cross-sectional area from the end near the flange soft part 3 to the end away from the flange soft part 3, which helps to optimize hydrodynamic characteristics and provide structural support. The gradually decreasing cross-sectional area design helps to accelerate milk flow, reduce fluid resistance, and improve milk expression efficiency. The smaller cross-sectional area helps to disperse pressure on the nipple and reduce discomfort or pain caused by concentrated suction. The larger cross-sectional area of ​​the blocking member 2 near the flange soft part 3 can provide better structural stability, ensuring that the breast shield 100 maintains the proper position during milk expression. The soft material of the flange soft part 3 and the change in cross-sectional area of ​​the blocking member 2 help the breast shield 100 better fit different breast shapes, improving sealing and comfort.

[0038] Please see Figure 2 In one embodiment of this utility model, the cross-section of the blocking member 2 is arc-shaped in the extending direction of the breast pumping channel 1. The arc-shaped cross-section of the blocking member 2 helps to conform to the natural curve of the breast, providing a more comfortable fit; the arc-shaped cross-section helps to optimize fluid dynamics, making milk flow smoother and reducing flow resistance; the arc-shaped design can better adapt to the natural shape of the breast, reducing pressure and providing a more comfortable breast pumping experience; the arc-shaped cross-section helps to disperse pressure on the nipple, reducing the risk of nipple damage caused by concentrated suction; the arc-shaped cross-section helps to guide milk flow to the liquid passage 21, improving breast pumping efficiency and ensuring smooth milk flow.

[0039] This utility model also proposes a breast pump, which includes a main unit, a milk storage container, and a breast shield 100. The specific structure of the breast shield 100 is as described in the above embodiments. Since this breast pump adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The breast shield 100 is detachably connected to the main unit; the milk storage container is detachably connected to the main unit.

[0040] In this embodiment, the main unit is the core of the breast pump, responsible for providing suction and controlling the milk expression process. It typically includes a motor, pump, control panel, and power supply. The breast shield 100 is the part that directly contacts the breast and is used to collect milk. The breast shield 100 includes special designs such as a blocking element 2 and a liquid passage 21 to improve the comfort and efficiency of milk expression. The milk storage container is used to collect and store the expressed milk. The detachable connection makes each component easier to clean and maintain, helps maintain the hygiene of the device, and extends its service life. Users can replace different models of breast shields as needed. The breast pump can be fitted with either a breast shield 100 or a milk storage container to suit different usage scenarios and personal preferences. The detachable design makes the breast pump easier to disassemble, carry, and store. If a component is damaged or needs to be upgraded, the user can replace that component individually without replacing the entire breast pump, reducing usage costs. The main unit is detachably connected to the breast shield 100 and the milk storage container. This can be achieved by providing threaded structures on the main unit, breast shield 100, and milk storage container, or by providing a slot on the main unit and a buckle on the breast shield 100 and milk storage container. This utility model does not limit the specific connection.

[0041] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
