[0024] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0025] Example 1:

[0026] like Figure 1-5 As shown,

[0027] On one hand, the present invention provides a breast shield that is easy to manufacture, including a front cover 1, a flange ring 11, and a rear cover 12; the flange ring 11 is located on the side of the front cover 1 facing away from the breast, and the flange ring 11 is arranged around the outer edge of the front cover 1, and the inner ring of the flange ring 11 is provided with an inwardly extending folded edge 13; the rear cover 12 fits against the side of the front cover 1 facing away from the breast, and the outer edge of the rear cover 12 is sealed and embedded in the folded edge 13; the front cover 1, the flange ring 11, and the folded edge 13 are integrally formed; the material hardness of the rear cover 12 is greater than that of the front cover 1, the flange ring 11, and the folded edge 13; the front cover 1 is provided with a breast suction channel passing through the rear cover 12, and the breast suction channel is connected to the negative pressure inlet end of the breast pump.

[0028] When the breast shield provided in this embodiment is manufactured, the back cover 12 is made of hard plastic, while the front cover 1, flange ring 11, and folded edge 13 are all made of soft plastic. First, the harder back cover 12 is injection molded. Then, the back cover 12 is placed in a mold for overmolding with soft plastic. By using the harder back cover 12 as a supporting frame, the front cover 1, flange ring 11, and folded edge 13 are injection molded and wrapped around the back cover 12, forming an overmolded structure. After overmolding, the front cover 1 and back cover 12 are in a fitted state. The flange ring 11 wraps around the outer ring of the back cover 12, and the folded edge 13 wraps around the side of the back cover 12 facing away from the breast, so that the back cover 12 is embedded between the flange ring 11 and the folded edge 13. This not only fixes the front cover 1 and back cover 12 but also provides a sealing effect. Because the rear cover 12 is made of a relatively hard material, it can act as a supporting frame during the overmolding process. It can provide support for softer, more easily deformed rubber materials, resulting in higher injection molding precision and less deformation after cooling, effectively improving the product yield. Therefore, by overmolding the front cover 1, flange ring 11, and folded edge 13 onto the rear cover 12, the defect rate of soft rubber injection molding can be effectively reduced, and production efficiency improved.

[0029] The breast shield provided in this embodiment is easy to manufacture. By using a relatively rigid back cover 12 as a supporting frame and wrapping the front cover 1, flange ring 11 and folded edge 13 with rubber to the back cover 12, the deformation of the soft rubber part during the injection molding process is reduced, which effectively improves the yield of the product.

[0030] To further improve the comfort of the product, in a preferred embodiment, a heating element 14 is also included, sandwiched between the front cover 1 and the rear cover 12. The heating element 14 has a clearance along the path of the breast pump channel. The heating element 14 is connected to a circuit interface 2. The power circuit of the breast pump is connected to the circuit interface 2, and the heating element 14 is connected to the power source through the circuit interface 2. The heating element 14 has a resistance wire inside, which heats the front cover 1 when energized, making the front cover 1 closer to the body temperature and improving comfort.

[0031] The breast shield provided in this embodiment is easy to manufacture. By setting an electrically heated heating element 14 to heat the front cover 1, the front cover 1 is closer to the body temperature, which can improve the comfort of use.

[0032] In a preferred embodiment, the rear cover 12 is made of plastic. The rear cover 12 can be made of hard plastic materials such as polypropylene and polycarbonate, which are not easily deformed during injection molding, have good hardness and strength, and are suitable as a structural skeleton, and then covered with soft plastic.

[0033] In a preferred embodiment, the front cover 1, flange ring 11, and folded edge 13 are made of silicone. Silicone is soft and elastic, allowing for better contact with the breast and reducing discomfort. It also provides a good seal, aiding in the extraction of milk.

[0034] In a preferred embodiment, an annular protrusion 3 is provided at the root of the opening of the front cover 1; the annular protrusion 3 is arranged circumferentially along the inner wall of the opening of the front cover 1; the annular protrusion 3 has a trumpet-shaped structure and expands and extends toward the liquid inlet direction of the front cover 1.

[0035] When the breast pump provided in this embodiment needs to be attached to the breast for breast pumping, the front cover 1 is first pressed onto the breast, with the annular protrusion 3 aligned with the areola. After pressing, a sealed space is formed between the annular protrusion 3 and the areola, and a sealed area is also formed between the breast area around the areola and the front cover 1. If the annular protrusion 3 detaches from the areola and loses its seal during breast pumping, the sealed area formed between the breast area around the areola and the front cover 1 ensures that the breast pump continues to function normally. In addition, since the areola area is relatively small, sealing this area with the annular protrusion 3 makes it easier to adapt to the shape of the areola, resulting in better applicability.

[0036] The present invention provides a breast pump that is easy to manufacture. By setting an annular protrusion 3, it can form two sealing areas on the breast with the front cover 1, which can effectively improve the sealing reliability of the breast pump. The annular protrusion 3 can be attached to the areola to better fit breasts of different shapes, improving applicability to different users and ease of use.

[0037] In a preferred embodiment, the annular protrusion 3 is coaxially arranged with the front cover 1. This coaxial arrangement allows for better positioning of the inner annular protrusion 3 based on the position of the outer front cover 1, enabling faster alignment with the areola and improving ease of use.

[0038] On the other hand, the present invention provides a wearable breast pump, including a breast shield, a negative pressure part and a liquid storage part; the breast shield is located at the liquid inlet end of the negative pressure part; the liquid storage part is located at the liquid outlet end of the negative pressure part; the liquid storage part includes a container body 4 and a side cover 5; the side of the container body 4 is open and has a cover opening 41; the side cover 5 is sealed and closed to the cover opening 41; the container body 4 is also provided with a connection port 6 for connecting the breast pump in the area outside the cover opening 41.

[0039] When the wearable breast pump provided by this utility model needs to store the expressed milk, the connection port 6 of the container body 4 is connected to the breast pump. The breast pump stores the milk in the container body 4 through the connection port 6. After storage is completed, the container body 4 is separated from the breast pump, and then the side cover 5 is removed. The inside of the container body 4 is cleaned through the open cover 41.

[0040] In this embodiment, by removing the connection port 6 from the original cover, the container body 4 is directly connected to the connection port 6 instead of through the cover. This effectively improves the connection strength between the container body 4 and the connection port 6. Even when the container body 4 is full of milk and its weight increases, it can still be effectively connected to the breast pump without falling off.

[0041] To ensure the side cover 5 can be effectively installed in the cap opening 41, in a preferred embodiment, the side cover 5 facing the cap opening 41 is provided with an annular plate 51; the annular plate 51 extends towards the cap opening 41 and enters the cap opening 41; the outer ring of the annular plate 51 is provided with a sealing structure. When closing, the side cover 5 is aligned with the cap opening 41, and the annular plate 51 is first inserted into the cap opening 41. At this time, the sealing structure of the outer ring of the annular plate 51 is sandwiched between the annular plate 51 and the inner wall of the cap opening 41. The sealing structure serves two purposes: firstly, it secures the annular plate 51, making it difficult for the side cover 5 to slip out; secondly, it seals the side cover 5 with the cap opening 41, preventing milk from leaking out.

[0042] To further improve the sealing effect of the sealing structure between the side cover 5 and the cover opening 41, the sealing structure further includes a sealing strip 52, a first sealing ring 53, and a second sealing ring 54. The sealing strip 52 is fitted onto and covers the outer circumferential surface of the ring plate 51. The first sealing ring 53 and the second sealing ring 54 are sequentially connected circumferentially to the outer circumferential surface of the sealing strip 52 along its width direction. The sealing strip 52, the first sealing ring 53, and the second sealing ring 54 can be made of rubber and are integrally molded. When installing the side cover 5, the sealing strip 52 is fitted onto the outer circumferential surface of the ring plate 51, with the first sealing ring 53 and the second sealing ring 54 facing outwards. Then, the side cover 5 is closed, causing the sealing strip 52, the first sealing ring 53, and the second sealing ring 54 to be deformed by the compression of the ring plate 51 and the inner wall of the cover opening 41, which can fill the gap between the ring plate 51 and the inner wall of the cover opening 41, thus sealing them. By setting the first sealing ring 53 and the second sealing ring 54, the sealing path can be increased and the sealing pressure can be distributed, resulting in better sealing performance of the sealing structure.

[0043] To facilitate the removal of the side cover 5, in a preferred embodiment, the top of the side cover 5 is provided with a handle 55. When it is necessary to remove the side cover 5, the user can use the handle 55 to exert force more effectively and remove the side cover 5 more easily.

[0044] In a preferred embodiment, the connection port 6 is located at the top of the container body 4. The container body 4 is connected to the breast pump through the connection port 6 at the top. As milk is continuously poured into the container body 4 and its weight gradually increases, the connection port 6 at the top of the container body 4, compared to the technical solution where the connection port is located on the side of the container body 4, can better maintain the structural strength under vertical force, thus preventing the container body 4 from detaching from the breast pump and falling.

[0046] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
