[0033] The following description of exemplary embodiments of the present disclosure is made in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding. These details should be considered as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0034] In the related art, the sealing performance of the connection between the suction piece and the main body of the breast pump is poor, and there will be a problem of air leakage when the breast pump is sucking milk from the breast, that is, air will enter the breast pump. In this case, the negative pressure formed inside the breast pump when sucking milk is not large enough, resulting in poor milk suction effect.

[0035] To solve the above-mentioned technical problems, the present disclosure provides an adsorbent and a breast pump, comprising a first cover body for covering a breast and a connecting portion for connecting to a breast pump body, wherein a first end of the first cover body along a first direction is for attaching to the breast; the connecting portion is for connecting the interior of the first cover body with the interior of the breast pump body, and the connecting portion comprises a flexible portion fitted on the breast pump body and a rigid portion for supporting the flexible portion; the flexible portion is connected to a second end of the first cover body along the first direction. According to the solution of the present disclosure, by providing the flexible portion to fit the breast pump body, the sealing performance of the connection between the adsorbent and the breast pump body can be improved, thereby preventing air leakage; providing the rigid portion to support the flexible portion can, on the one hand, prevent excessive deformation of the flexible portion, thereby ensuring the stability of the negative pressure environment of the breast pump during milk extraction, so that the breast pump can continuously and stably extract milk; and on the other hand, providing the rigid portion to support the flexible portion can improve the convenience of connecting the adsorbent to the breast pump body.

[0036] The present disclosure provides an adsorption member, such as Figures 1 to 5 As shown, it includes a first cover body 1 for covering the breast and a connecting portion 2 for connecting to the breast pump body 4. The first end of the first cover body 1 along the first direction A is used to be attached to the breast.

[0037] The first cover body 1 is connected to the connecting portion 2 at the second end thereof along the first direction A. The first end and the second end of the first cover body 1 are two opposite ends of the first cover body 1 in the first direction A, wherein the first direction A can be understood as the axial direction of the first cover body 1, such as Figure 1 Direction indicated by the arrow.

[0038] The first cover body 1 can be understood as a structure that is covered on the breast. When the first cover body 1 is covered on the breast, the breast can be located in the internal space of the first cover body 1, that is, the breast is located in the area surrounded by the inner surface of the first cover body 1.

[0039] The first end of the first cover body 1 is an open end that communicates with the interior space of the first cover body 1. When the first cover body 1 is placed over a breast, the breast enters the interior space of the first cover body 1 through the first end. The second end of the first cover body 1 is a structure that communicates with the interior space of the first cover body 1 and is connected to the connecting portion 2.

[0040] To adapt to the shape of the breast, the first end of the first shield 1 has a larger diameter, while the second end has a smaller diameter, with the diameter gradually decreasing from the first end to the second end, thereby making the first shield 1 roughly trumpet-shaped. When the first shield 1 is placed over the breast, the portion near the areola can be attached to the inner surface of the first shield 1 near the second end.

[0041] According to an embodiment of the present disclosure, by providing the first cover body 1, when using the breast pump body 4, the suction member can be better covered on the breast, thereby making it easier for the user to express milk through the breast pump.

[0042] In one embodiment, the connecting portion 2 is used to connect the interior of the first cover body 1 with the interior of the breast pump body 4. The connecting portion 2 includes a flexible portion that is mounted on the breast pump body 4 and a rigid portion for supporting the flexible portion; the flexible portion is connected to the second end of the first cover body 1 along the first direction A.

[0043] According to the embodiments of the present disclosure, it should be noted that:

[0044] The relevant introduction of the first cover body 1 can refer to the introduction of the first cover body 1 in the above embodiment, and will not be repeated here.

[0045] The connecting portion 2 includes a flexible portion and a rigid portion. The flexible portion is sleeved and connected to the breast pump body 4. The sleeved connection can be understood as the flexible portion being sleeved onto the outer surface of the open end of the breast pump body 4, or the open end of the breast pump body 4 being sleeved onto the outer surface of the flexible portion. The rigid portion is used to support the flexible portion. It can be understood that the rigid portion has a greater hardness than the flexible portion, and thus, when the flexible portion is sleeved and connected to the breast pump body 4, the rigid portion provides support. The relative positional relationship between the rigid portion and the flexible portion can be various, for example, the rigid portion can be located on the inner surface of the flexible portion, the rigid portion can be located on the outer surface of the flexible portion, or the rigid portion can be located inside the flexible portion (i.e., the flexible portion completely encloses the rigid portion).

[0046] The flexible part is connected to the second end of the first cover body 1. It can be understood that the flexible part and the first cover body 1 can be an integral structure formed in one piece, or a split structure that can be detachably connected to the first cover body 1, as long as the outer surface of the connecting part 2 is smoothly transitioned to the outer surface of the first cover body 1 to improve the user experience.

[0047] The rigid portion may be directly connected to the second end of the first cover body 1 , or may be connected to the second end of the first cover body 1 through the flexible portion.

[0048] In some embodiments, the interior of the connecting portion 2 has a connecting hole 21. The axial direction of the connecting hole 21 can be the same as the first direction A. The connecting hole 21 can be used to connect the interior of the first cover 1 with the interior of the breast pump body 4. That is, the interior of the first cover 1 and the interior of the breast pump body 4 are connected through the connecting hole 21. When the breast pump body 4 is in operation, the suction generated by the breast pump is transferred to the interior space of the first cover 1 through the connecting hole 21, creating a negative pressure in the interior space of the first cover 1, thereby allowing the first cover 1 to firmly adhere to the breast to absorb milk. When the first cover 1 is covering the breast, the nipple and at least part of the areola, or the nipple, can extend through the connecting hole 21 and enter the breast pump body 4.

[0049] In one embodiment, the connecting portion 2 is provided with a protrusion for abutting against the areola. During the breast pumping process, the protrusion can abut against and stimulate the areola, thereby promoting the secretion of milk.

[0050] The protrusion can be provided at the end of the connecting portion 2 that abuts against the breast pump body (e.g. Figure 1 and Figure 5 As shown); alternatively, the protrusion can also be arranged in the through hole of the connecting portion 2.

[0051] In another embodiment, the protrusion includes a plurality of first protrusions 22, which are spaced apart along the circumference of the connecting portion 2. The number of the plurality of first protrusions 22 can be adjusted as needed. For example, the protrusion can include a plurality of dot-shaped first protrusions 22 or a plurality of sheet-shaped first protrusions 22 spaced apart along the circumference of the connecting hole 21. It can also include multiple layers of protrusions spaced apart along the axial direction of the connecting hole 21, and each layer of protrusions can include a plurality of dot-shaped first protrusions 22 or a plurality of sheet-shaped first protrusions 22 spaced apart along the circumference of the connecting hole 21. The first protrusions 22 in the multiple layers of protrusions can be arranged side by side along the first direction A or staggered.

[0052] In one embodiment, the plurality of first protrusions 22 can be arranged at uniform intervals or non-uniform intervals along the circumference of the communicating hole 21, and can be adjusted as needed. In one embodiment, the protrusion height of the first protrusion 22 can be adjusted, for example, a first protrusion 22 with a lower protrusion height is set to simulate the oral environment of a young baby. Or a first protrusion 22 with a higher protrusion height is set to simulate the oral environment of an older baby. The protrusion heights between the plurality of first protrusions 22 can be the same or different, and can be adjusted. The plurality of first protrusions 22 are arranged along the circumference of the communicating hole 21 so that the areola can abut against the plurality of first protrusions 22, further stimulating the breast to secrete milk. In one embodiment, the protrusion can be made of a flexible material, such as silicone, and can be specifically set according to the circumstances.

[0053] According to the embodiment of the present disclosure, by providing the connecting portion 2, the first cover body 1 can be connected to the breast pump body 4, so that the internal space of the first cover body 1 forms a negative pressure environment, so that the breast pump body 4, the first cover body 1 and the connecting portion 2 cooperate to suck the milk. After the milk is sucked, the milk flows into the milk storage part of the breast pump body 4. By providing the flexible portion to cover the breast pump body 4, the sealing of the connection can be improved to prevent air leakage. By providing the rigid portion to support the flexible portion, the flexible portion can be prevented from excessive deformation, thereby ensuring the stability of the negative pressure environment. The negative pressure environment of the breast pump is kept stable during the milk extraction process, so that the breast pump can continuously and stably suck the milk. On the other hand, by providing the rigid portion to support the flexible portion, the convenience of connecting the suction part to the breast pump body 4 can be improved.

[0054] In the related art, when a breast pump is used to suck milk from the breast, the user needs to hold the breast pump in hand to ensure that it is firmly attached to the breast. Holding the breast pump for a long time will be tiring and the breast pump may leak due to unstable holding, thus leading to problems with sucking milk.

[0055] In order to solve the above technical problems, the present disclosure provides an adsorption member, such as Figures 2 to 5 As shown, the adsorbent also includes a second cover body 3 arranged in the first cover body 1, and the second cover body 3 is used to attach to part of the breast. One end of the second cover body 3 is connected to the second end of the first cover body 1, and the other end of the second cover body 3 extends in a direction close to the first end of the first cover body 1. When the first cover body 1 and the second cover body 3 are attached to the breast, a cavity is formed between the inner wall of the first cover body 1 and the outer wall of the second cover body 3 and the breast.

[0056] According to the embodiments of the present disclosure, it should be noted that:

[0057] The first cover 1 can be described in the foregoing description of the first cover 1 in any embodiment, and will not be described in detail. The connection portion 2 can be described in the foregoing description of the connection portion 2 in any embodiment, and will not be described in detail.

[0058] A second shield 3 is disposed within the first shield 1. One end of the second shield 3 is connected to the second end of the first shield 1, while the other end of the second shield 3 extends toward the first end of the first shield 1. However, the extension length of the second end of the second shield 3 is less than the extension length of the first end of the first shield 1. That is, when the first shield 1 is applied to the breast, the first end of the first shield 1 is attached to the posterior region of the breast, while the other end of the second shield 3 is attached to the middle or front region of the breast. Assuming that the first end of the first shield 1 is attached to a first position on the breast, the other end of the second shield 3 can be attached to a second position on the breast, which is between the first position and the nipple.

[0059] In one example, if Figures 2 to 5As shown, the second cover body 3 extends along the circumference of the first cover body 1 to form an annular second cover body 3, and the axes of the first cover body 1 and the second cover body 3 coincide with each other.

[0060] By providing the first cover body 1 and the second cover body 3, when the suction piece is attached to the breast and the breast pump is used to express milk, a negative pressure is generated in the cavity between the second cover body 3, the first cover body 1 and the breast, which can make the suction piece more firmly attached to the breast, prevent the suction piece from falling off the breast, and reduce the user's hand-held operation.

[0061] When using the suction piece, the first cover body 1 is placed on the breast, and the first end of the first cover body 1 is fitted with the back part of the breast (the part close to the body), so that the breast is located in the internal space of the first cover body 1, and the other end of the second cover body 3 is fitted with the front part of the breast (the part close to the areola and nipple). When the suction piece and the breast pump body 4 cooperate to suck milk, a negative pressure can be formed in the internal space of the first cover body 1 and the second cover body 3. In the negative pressure environment, the milk produced by the nipple will flow into the milk storage part of the breast pump body 4 to complete the sucking work; at the same time, a negative pressure can be formed in the cavity. In the negative pressure environment, the first cover body 1 and the second cover body 3 can be firmly adsorbed on the breast, reducing the user's hand-held operation and improving the user experience.

[0062] According to the embodiment of the present disclosure, by arranging the second cover body 3 inside the first cover body 1, a double-layer adsorption structure can be formed, which increases the firmness of the adsorption part adsorbed on the breast and prevents the user from holding the breast pump for a long time. At the same time, the double-layer adsorption structure can better achieve a seal between the breast and the adsorption part, which is beneficial to improving the breast suction effect.

[0063] In one embodiment, the second cover body 3 includes a connecting section 31 and a cover section 32 connected to the connecting section 31, and the end of the connecting section 31 facing away from the cover section 32 is connected to the second end of the first cover body 1; with the plane perpendicular to the first direction A as the cross-section, the area of ​​the cross-section of the area enclosed by the cover section 32 increases in the direction away from the connecting section 31.

[0064] The connecting section 31 can be understood as the portion of the second housing 3 that is used to connect to the first housing 1. The relative positions of the connecting section 31, the second end of the first housing 1, and the connecting portion 2 can be adjusted. For example, the second end of the first housing 1 includes an upper and lower end surface along the first direction A, wherein the upper end surface is connected to the connecting portion 2, and the lower end surface is connected to the connecting section 31.

[0065] The shield section 32 can be understood as the portion of the second shield body 3 that is used to adhere to the breast. To adapt to the shape of the breast, the shield section 32 can be configured as, for example, a trumpet-shaped structure so that the shield section 32 can be better adhered to the breast.

[0066] In one embodiment, the cross-sectional area of ​​the region enclosed by the connecting segment 31 increases in a direction away from the shielding segment 32, as measured along a plane perpendicular to the first direction A. It can be understood that the dimension of the end of the connecting segment 31 connected to the shielding segment 32 is larger than the dimension of the end of the connecting segment 31 connected to the second shield 3, thereby forming a substantially inclined inner surface of the connecting segment 31. This allows the breast to smoothly flow through the connecting segment 31 into the breast pump body 4 after milk is secreted, completing the milk collection process.

[0067] In one embodiment, the cross-section of the region enclosed by the connecting segment 31 decreases in area away from the covering segment 32, taking a plane perpendicular to the first direction A as a cross-section. It can be understood that the size of the end of the connecting segment 31 connected to the covering segment 32 is set to be smaller than the size of the end of the connecting segment 31 connected to the second cover body 3. This can reduce the range of movement of the breast within the suction member and improve the breastfeeding experience.

[0068] In one embodiment, the rigid portion includes a first annular body 11 , and the flexible portion includes a third annular body 13 . The third annular body 13 at least partially covers the first annular body 11 .

[0069] In this embodiment, partial covering can be understood as the third annular body 13 covering at least one surface of the first annular body 11, for example, the third annular body 13 only covers the outer surface of the first annular body 11, the third annular body 13 only covers the inner surface of the first annular body 11, the third annular body 13 covers the outer surface and inner surface of the first annular body 11, and the third annular body 13 completely covers the first annular body 11.

[0070] In one embodiment, the third annular body 13 only covers the outer surface of the first annular body 11, that is, the inner surface of the third annular body 13 is connected to the outer surface of the first annular body 11. In one embodiment, the height of the first annular body 11 can be less than the height of the third annular body 13, so that the first annular body 11 is not directly connected to the second end of the first cover body 1, but is connected to the second end of the first cover body 1 through the third annular body 13. The height of the first annular body 11 can also be equal to the height of the third annular body 13, so that the first annular body 11 is directly connected to the second end of the first cover body 1. The position of the first annular body 11 relative to the second end of the first cover body 1 can be adjusted as needed, for example, the plane where the first annular body 11 is located is set perpendicular to the first direction A.

[0071] When the inner surface of the third annular body 13 is connected to the outer surface of the first annular body 11, the flexible portion can be sleeved on the breast pump body 4 in the following manner. For example, the third annular body 13 is sleeved on the outer side of the breast pump body 4 through the first annular body 11, that is, the first annular body 11 is sleeved on the outer side of the breast pump body 4. In this case, the third annular body 13 is connected to the outer surface of the first annular body 11. For another example, the first annular body 11 is sleeved on the inner side of the breast pump body 4 through the third annular body 13, that is, the third annular body 13 is sleeved on the inner side of the breast pump body 4. In this case, the first annular body 11 is connected to the outer surface of the third annular body 13.

[0072] In another embodiment, the third annular body 13 may be connected to all surfaces of the first annular body 11, that is, the third annular body 13 completely covers the first annular body 11. When the suction piece is connected to the breast pump body 4, the third annular body 13 is fitted onto the breast pump body 4, and the first annular body 11 is located inside the third annular body 13.

[0073] According to an embodiment of the present disclosure, the third annular body 13 is provided to at least partially cover the first annular body 11 , and when the adsorbent is connected to the breast pump body 4 , the third annular body 13 can be sleeved on the breast pump body 4 , thereby improving the stability of the sleeve connection.

[0074] In one embodiment, the connecting portion 2 further includes a second annular body 12 , and the first annular body 11 and the third annular body 13 form a clamping portion. An annular groove for clamping with the breast pump body 4 is formed between the clamping portion and the second annular body 12 .

[0075] In one embodiment, the second annular body 12 is located inside the engaging portion. It can be understood that the entire second annular body 12 is located inside the engaging portion. By arranging the second annular body 12 inside the engaging portion, the through hole of the second annular body 12 constitutes the communicating hole 21 of the connecting portion 2. The aforementioned protrusion is also provided on the inner surface of the second annular body 12.

[0076] The second annular body 12 can be connected to the second end of the first housing 1 or to the second housing 3 (i.e., connected to the connecting section 31). The second annular body 12 is located inside the engaging portion and is spaced apart from the engaging portion, so that an annular groove is formed therebetween. An annular protrusion is provided on one end of the breast pump body 4 for connecting to the suction member. When the breast pump body 4 is connected to the suction member, the annular protrusion engages with the annular groove, thereby strengthening the connection between the breast pump body 4 and the suction member, improving the sealing between the suction member and the breast pump body 4, and facilitating disassembly for easy cleaning.

[0077] In one embodiment, the bottom of the annular groove is protruded with an annular protrusion structure, and the end of the breast pump body 4 that is connected to the annular groove is provided with an annular groove structure. The two are adaptively connected to improve the sealing between the adsorption component and the breast pump body 4.

[0078] In another embodiment, the second annular body 12 is located outside the engaging portion. It can be understood that the entire second annular body 12 is located outside the engaging portion, and an annular groove is formed between the engaging portion and the second annular body 12 to engage with the breast pump body.

[0079] In one embodiment, the wall thickness of the second annular body 12 is greater than that of the first annular body 11 to increase the stability of the second annular body 12 and prevent the second annular body 12 from deforming when the adsorbent is connected to the breast pump body 4, thereby affecting the connection between the two.

[0080] In one embodiment, the wall thickness of the second annular body 12 may be greater than the sum of the wall thickness of the first annular body 11 and the wall thickness of the third annular body 13. The height of the second annular body 12 may be the same as that of the third annular body 13 and may be adjusted as needed.

[0081] In one embodiment, the second annular body 12 is made of a flexible material to increase the toughness of the second annular body 12 and facilitate connection of the adsorption element to the breast pump body 4.

[0082] In one embodiment, Figures 1 to 5 As shown, a plurality of second protrusions 23 are provided at intervals along the circumference of the first cover body 1 at the first end of the first cover body 1 , and a smooth transition between the plurality of second protrusions 23 forms a wave shape.

[0083] According to the embodiments of the present disclosure, it should be noted that:

[0084] The plurality of second protrusions 23 can be integrally formed with the first cover 1. A smooth transition is provided between the first cover 1 and the plurality of second protrusions 23 to enhance the user experience. The plurality of second protrusions 23 can be arranged at even or uneven intervals along the circumference of the first cover 1, and this can be adjusted. Furthermore, the heights of the plurality of second protrusions 23 can be the same or different.

[0085] The shape of the second protrusion 23 can be adjusted as needed. For example, the second protrusion 23 is a raised triangle, polygon or semicircle.

[0086] According to the embodiments of the present disclosure, by providing multiple second protrusions 23 on the first end of the first cover body 1, the contact area with the breast is increased when the first cover body 1 is placed over the breast, increasing the friction between the two and ensuring better adhesion of the first cover body 1 to the breast. The smooth transition between the multiple second protrusions 23 enhances the comfort of the suction member when in contact with the breast. The wavy shape formed by the multiple second protrusions 23 has a strong deformability, allowing the suction member to fit more closely to the breast, thereby facilitating the formation of a negative pressure space.

[0087] In one embodiment, the rigid portion is made of a rigid material.

[0088] Rigid materials refer to components that do not deform or deform very slightly and imperceptibly during use. Examples include hard plastics, hard glue, PPSU (Polyphenylene sulfone resins), and PP (Polypropylene).

[0089] According to an embodiment of the present disclosure, by providing a rigid portion made of a rigid material, the hardness of the connecting portion 2 is increased, thereby facilitating installation and removal of the adsorption component from the breast pump body 4.

[0090] In one embodiment, the first cover body 1 is made of a flexible material, and the first cover body 1 and the connecting portion 2 are an integral piece.

[0091] The first cover body 1 can be formed of a flexible material, and the flexible material can be flexible rubber, flexible silicone, latex, soft glue, etc. This can make the first cover body 1 better adhere to the breast, avoid air leakage between the first cover body 1 and the breast, and affect the efficiency of breast pumping.

[0092] The first housing 1 and the connecting portion 2 are integrally formed, and may be formed using a two-shot injection molding process or another process. For example, the first housing 1 and the flexible portion may be integrally formed, and then connected to the rigid portion using an encapsulation process. The connecting portion 2 and the first housing 1 may be integrally formed when the product is finished.

[0093] According to the embodiments of the present disclosure, by providing the first cover body 1 made of a flexible material, it can better fit the breast when it is placed on the breast. By configuring the first cover body 1 and the connecting portion 2 as a single piece, the connecting portion 2 can be firmly fixed to the breast pump body 4 while improving the adsorption capacity of the adsorption member. At the same time, it can prevent air leakage at the connection 2 between the first cover body 1 and the connecting portion 2, which are separate structures.

[0094] In one example, the second cover body 3 is made of a flexible material, that is, the second cover body 3 can be formed of a flexible material, and the flexible material can be flexible rubber, flexible silicone, latex, soft glue, etc. This allows the absorbent to better adhere to the breast, avoiding air leakage between the absorbent and the breast, which affects the efficiency of milk extraction.

[0095] The first cover 1 and the second cover 3 are integrally formed. If the second cover 3 is a flexible member, the first cover 1 and the second cover 3 can be formed into a single piece through an integrated molding process. According to the examples disclosed herein, when the breast pump body 4 is in operation, the sealing performance of the negative pressure environment within the suction element can be improved.
