[0046] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art 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.

[0047] In the related art, the sealing performance of the connection between the suction piece of the breast pump 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 a poor effect of sucking milk.

[0048] In order to solve the above 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 the first end of the first cover body along a first direction is used to adhere to the breast; the connecting portion is used to connect the interior of the first cover body with the interior of the breast pump body, and the connecting portion comprises a flexible portion sleeved on the breast pump body and a rigid portion for supporting the flexible portion; the flexible portion is connected to the second end of the first cover body along the first direction. According to the scheme of the present disclosure, by setting the flexible portion to sleeve the breast pump body, the sealing performance of the connection between the adsorbent and the breast pump body can be improved to avoid air leakage; by setting the rigid portion to support the flexible portion, on the one hand, the flexible portion can be prevented from being deformed excessively, ensuring the stability of the negative pressure environment of the breast pump during milk extraction, so that the breast pump can continuously and stably absorb milk; on the other hand, by setting the rigid portion to support the flexible portion, the convenience of connecting the adsorbent and the breast pump body can be improved.

[0049] The present disclosure provides an adsorption member, such as Figures 1 to 5 As shown, it comprises a first cover body 1 for covering a breast and a connecting portion 2 for connecting to a breast pump body 4. The first end of the first cover body 1 along a first direction A is used to adhere to the breast.

[0050] The second end of the first cover body 1 along the first direction A is connected to the connecting portion 2. 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. Figure 1 Direction indicated by the arrow.

[0051] 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.

[0052] The first end of the first cover body 1 is an open end connected to the internal space of the first cover body 1, and when the first cover body 1 covers the breast, the breast enters the internal space of the first cover body 1 through the first end. The second end of the first cover body 1 is a structure connected to the internal space of the first cover body 1 and connected to the connecting part 2.

[0053] To adapt to the shape of the breast, the first end of the first cover body 1 has a larger diameter, and the second end of the first cover body 1 has a smaller diameter, and the diameter gradually decreases from the first end to the second end, so that the first cover body 1 can be roughly in the shape of a trumpet. When the first cover body 1 covers the breast, a partial area near the areola can be attached to the inner surface of the first cover body 1 near the second end.

[0054] According to the embodiment of the present disclosure, by providing the first cover body 1, when the breast pump body 4 is used, the suction member can be better covered on the breast, thereby making it easier for the user to express milk through the breast pump.

[0055] 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, and the connecting portion 2 includes a flexible portion 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.

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

[0057] The relevant introduction of the first cover body 1 can refer to the introduction of the first cover body 1 in the above embodiment, which will not be repeated here.

[0058] The connecting part 2 includes a flexible part and a rigid part. The flexible part is connected with the breast pump body 4 in a sleeve-type connection. The sleeve-type connection can be understood as the flexible part being sleeved on 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 on the outer surface of the flexible part. The rigid part is used to support the flexible part. It can be understood that the hardness of the rigid part is greater than the hardness of the flexible part. Then, when the flexible part is sleeve-type connected with the breast pump body 4, the rigid part plays a supporting role. There can be various relative positional relationships between the rigid part and the flexible part. For example, the rigid part is located on the inner surface of the flexible part, or the rigid part is located on the outer surface of the flexible part, or the rigid part is located inside the flexible part (i.e., the flexible part completely wraps the rigid part).

[0059] 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 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.

[0060] 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.

[0061] In some embodiments, the connection portion 2 has a connecting hole 21 inside, and 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 inside of the first cover 1 with the inside of the breast pump body 4, that is, the inside of the first cover 1 and the inside of the breast pump body 4 are connected through the connecting hole 21; when the breast pump body 4 is working, the suction force generated by the breast pump is transferred to the internal space of the first cover 1 through the connecting hole 21, so that the internal space of the first cover 1 forms a negative pressure, so that the first cover 1 can be firmly attached to the breast to absorb milk. When the first cover 1 covers 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.

[0062] In one embodiment, the connecting portion 2 is provided with a protrusion for abutting against the areola. During the process of breast pumping, the protrusion can abut against and stimulate the areola, thereby promoting the secretion of milk.

[0063] The protrusion can be arranged at the end of the connecting part 2 that abuts against the breast pump body (such as Figure 1 and Figure 5 As shown); alternatively, the protrusion may also be arranged in the through hole of the connecting portion 2.

[0064] In another embodiment, the protrusion includes a plurality of first protrusions 22, and the plurality of first protrusions 22 are arranged at intervals 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 arranged at intervals along the circumference of the connecting hole 21, or a plurality of multi-layer protrusions arranged at intervals along the axial direction of the connecting hole 21, and each layer of the protrusion can include a plurality of dot-shaped first protrusions 22 or a plurality of sheet-shaped first protrusions 22 arranged at intervals along the circumference of the connecting hole 21, wherein the first protrusions 22 in the multi-layer protrusions can be arranged side by side along the first direction A or staggered.

[0065] In one embodiment, the plurality of first protrusions 22 may be arranged at uniform intervals or non-uniform intervals along the circumference of the connecting hole 21, and may be adjusted as needed. In one embodiment, the protrusion height of the first protrusion 22 may be adjusted, for example, a first protrusion 22 with a lower protrusion height is arranged to simulate the oral environment of a small-month-old baby. Or a first protrusion 22 with a higher protrusion height is arranged to simulate the oral environment of a large-month-old baby. The protrusion heights between the plurality of first protrusions 22 may be the same or different, and may be adjusted. The plurality of first protrusions 22 are arranged along the circumference of the connecting hole 21, so that the areola may abut against the plurality of first protrusions 22, further stimulating the breast to secrete milk. In one embodiment, the protrusion may be made of a flexible material, such as silicone, and may be specifically arranged according to the circumstances.

[0066] According to the embodiment of the present disclosure, by providing the connection part 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 cooperates with the first cover body 1 and the connection part 2 to absorb the milk, and after the milk is absorbed, the milk flows into the milk storage part of the breast pump body 4. By providing the flexible part to cover the breast pump body 4, the sealing of the connection can be improved to avoid air leakage, and the rigid part supporting the flexible part can be provided to avoid excessive deformation of the flexible part, so as to ensure the stability of the negative pressure environment and the stability of the negative pressure environment of the breast pump during the milk extraction process, so that the breast pump can continuously and stably absorb the milk, and on the other hand, the rigid part supporting the flexible part can improve the convenience of connecting the adsorption part with the breast pump body 4.

[0067] In the related art, when a breast pump is used to suck milk from a breast, the user needs to hold the breast pump by hand to keep it 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 unsmooth sucking.

[0068] 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 adhere to a 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 toward the 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.

[0069] According to the embodiments of the present disclosure, it should be noted that:

[0070] The related introduction of the first cover body 1 can refer to the introduction of the first cover body 1 in any of the above embodiments, and will not be repeated. The related introduction of the connecting portion 2 can refer to the introduction of the connecting portion 2 in any of the above embodiments, and will not be repeated.

[0071] A second cover body 3 is arranged inside the first cover body 1, 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 toward the first end of the first cover body 1, but the extension length of the other end of the second cover body 3 is less than the extension length of the first end of the first cover body 1, that is, when the first cover body 1 covers the breast, the first end of the first cover body 1 is attached to the rear area of ​​the breast, and the other end of the second cover body 3 is attached to the middle area or the front area of ​​the breast. Assuming that the first end of the first cover body 1 is attached to the first position of the breast, the other end of the second cover body 3 can be attached to the second position of the breast, and the second position is located between the first position and the nipple.

[0072] 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.

[0073] 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, so that the suction piece can be more firmly attached to the breast, thereby preventing the suction piece from falling off the breast and reducing the user's hand-held operations.

[0074] When using the suction device, 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 the nipple). When the suction device and the breast pump body 4 cooperate to suck milk, 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 emulsion produced by the nipple will flow into the milk storage part of the breast pump body 4 to complete the milk sucking work; at the same time, 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's experience.

[0075] According to the embodiment of the present disclosure, by setting 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 to 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 the seal between the breast and the adsorption part, which is beneficial to improving the breast suction effect.

[0076] 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 away from the cover section 32 is connected to the second end of the first cover body 1; taking the plane perpendicular to the first direction A as the cross-section, the cross-sectional area of ​​the area enclosed by the cover section 32 increases along the direction away from the connecting section 31.

[0077] The connecting section 31 can be understood as the portion of the second cover body 3 used to connect with the first cover body 1. The relative positions among the connecting section 31, the second end of the first cover body 1 and the connecting portion 2 can be adjusted. For example, the second end of the first cover body 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.

[0078] The shielding section 32 can be understood as the part of the second shield body 3 used to adhere to the breast. To adapt to the shape of the breast, the shielding section 32 can be set to, for example, a trumpet-shaped structure so that the shielding section 32 can be better attached to the breast.

[0079] In one embodiment, with the plane perpendicular to the first direction A as the cross section, the cross-sectional area of ​​the region enclosed by the connecting segment 31 increases in the direction away from the shielding segment 32. It can be understood that the size of the end of the connecting segment 31 connected to the shielding segment 32 is set to be larger than the size of the end of the connecting segment 31 connected to the second shield 3, so that the inner surface of the connecting segment 31 roughly forms an inclined surface, so that after the breast secretes milk, the milk can smoothly flow through the connecting segment 31 into the breast pump body 4 to complete the collection of the milk.

[0080] In one embodiment, with the plane perpendicular to the first direction A as the cross section, the area of ​​the cross section of the region enclosed by the connecting segment 31 decreases in the direction away from the shielding segment 32. It can be understood that the size of the end where the connecting segment 31 is connected to the shielding segment 32 is smaller than the size of the end where the connecting segment 31 is connected to the second shield body 3, which can reduce the range of movement of the breast in the suction piece and improve the breast pumping experience.

[0081] In one embodiment, the rigid portion includes a first annular body 11 , and the flexible portion includes a third annular body 13 , and the third annular body 13 at least partially covers the first annular body 11 .

[0082] 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 the inner surface of the first annular body 11, and the third annular body 13 completely covers the first annular body 11.

[0083] 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 setting 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 to be perpendicular to the first direction A.

[0084] 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, at this time, 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, at this time, the first annular body 11 is connected to the outer surface of the third annular body 13.

[0085] In another embodiment, the third annular body 13 may also 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 adsorbent is connected to the breast pump body 4, the third annular body 13 is connected to the breast pump body 4 in a sleeve-type manner, and the first annular body 11 is located inside the third annular body 13.

[0086] According to an embodiment of the present disclosure, a 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.

[0087] In one embodiment, the connecting portion 2 further comprises a second annular body 12 , the first annular body 11 and the third annular body 13 form a clamping portion, and an annular groove for clamping with the breast pump body 4 is formed between the clamping portion and the second annular body 12 .

[0088] In one embodiment, the second annular body 12 is located inside the engaging portion, which can be understood as the entire second annular body 12 being located inside the engaging portion, and 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 above-mentioned protrusion is also arranged on the inner surface of the second annular body 12.

[0089] The second annular body 12 can be connected to the second end of the first cover body 1, or connected to the second cover body 3 (i.e., connected to the connecting section 31). The second annular body 12 is located at the inner side of the clamping part and is spaced apart from the clamping part so that an annular groove is formed therebetween. An annular protrusion is provided at one end of the breast pump body 4 for connecting with the adsorbent. When the breast pump body 4 is connected with the adsorbent, the annular protrusion is engaged with the annular groove so that the breast pump body 4 is more firmly connected with the adsorbent, the sealing between the adsorbent and the breast pump body 4 is improved, and the disassembly is facilitated so as to facilitate the disassembly and cleaning.

[0090] 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, and the two are adaptively connected to improve the sealing between the adsorption component and the breast pump body 4.

[0091] In another embodiment, the second annular body 12 is located outside the engaging portion, which can be understood as the entire second annular body 12 is located outside the engaging portion, and an annular groove engaged with the breast pump body is formed between the engaging portion and the second annular body 12.

[0092] 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 and affecting the connection between the adsorbent and the breast pump body 4 when the adsorbent is connected.

[0093] 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 the height of the third annular body 13, which may be adjusted as needed.

[0094] In one embodiment, the second annular body 12 is made of a flexible material to improve the toughness of the second annular body 12 and facilitate the connection of the adsorption member with the breast pump body 4.

[0095] In one embodiment, Figures 1 to 5 As shown, a plurality of second protrusions 23 are arranged 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.

[0096] According to the embodiments of the present disclosure, it should be noted that:

[0097] The plurality of second protrusions 23 can be integrally formed with the first cover body 1. There is a smooth transition between the first cover body 1 and the plurality of second protrusions 23 to improve the user experience. The plurality of second protrusions 23 can be arranged at uniform intervals or non-uniform intervals along the circumference of the first cover body 1, which can be adjusted. Furthermore, the protrusion heights between the plurality of second protrusions 23 can be the same or different.

[0098] The shape of the second protrusion 23 can be adjusted as needed. For example, the second protrusion 23 is a protruding triangle, polygon or semicircle.

[0099] According to the embodiment of the present disclosure, by providing a plurality of second protrusions 23 at the first end of the first cover body 1, when the first cover body 1 covers the breast, the contact area with the breast is increased, the friction between the two is increased, and the first cover body 1 is better attached to the breast. The smooth transition between the plurality of second protrusions 23 can increase the comfort when the adsorbent contacts the breast. The wave shape formed by the plurality of second protrusions 23 has a strong deformation ability, which can make the adsorbent fit more closely to the breast, which is conducive to forming a negative pressure space.

[0100] In one embodiment, the rigid portion is made of a rigid material.

[0101] Rigid materials refer to components that will not deform or will deform very slightly and imperceptibly during use, such as hard plastic, hard glue, PPSU (Polyphenylene sulfone resins), PP (Polypropylene), etc.

[0102] According to the embodiment of the present disclosure, by providing a rigid part made of a rigid material, the hardness of the connecting part 2 is increased, thereby facilitating the installation and removal of the adsorption component from the breast pump body 4.

[0103] 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.

[0104] The first cover body 1 may be formed of a flexible material, and the flexible material may be flexible rubber, flexible silicone, latex, soft glue, etc. This allows the first cover body 1 to be better attached to the breast, thereby preventing air leakage between the first cover body 1 and the breast, which would affect the efficiency of breast suction.

[0105] The first cover body 1 and the connection part 2 are an integral part, which can be an integral part formed by a double-material injection molding process, or an integral part formed by other processes. For example, the first cover body 1 and the flexible part are integrally formed, and then the connection with the rigid part is completed by a rubber coating process. When the product is completed, the connection part 2 and the first cover body 1 are an integral part.

[0106] According to the embodiment of the present disclosure, by providing the first cover body 1 of a flexible material, when it covers the breast, it can better fit the breast. By providing the first cover body 1 and the connecting part 2 as an integral piece, the connecting part 2 can be fixed firmly to the breast pump body 4, and the adsorption capacity of the adsorption part can be improved. At the same time, the phenomenon of air leakage in the connecting part 2 between the first cover body 1 and the connecting part 2 of the separate structure can be avoided.

[0107] 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 can make the absorbent better attached to the breast, avoiding air leakage between the absorbent and the breast, which affects the efficiency of breast suction.

[0108] The first cover body 1 and the second cover body 3 are an integral part, and when the second cover body 3 is a flexible part, the first cover body 1 and the second cover body 3 can be processed into an integral part through an integrated processing and molding process. According to the example disclosed in the present invention, when the breast pump body 4 is working, the sealing of the negative pressure environment in the internal space of the adsorbent can be improved. In one example, the first cover body 1, the second cover body 3, and the connecting part 2 are an integral part, and when the breast pump body 4 is working, the sealing of the negative pressure environment in the internal space of the adsorbent can be further improved.

[0109] The present disclosure provides a breast pump, such as Figure 6 As shown, including:

[0110] The breast pump body 4 and the adsorbent in any of the above embodiments, the connecting portion 2 of the adsorbent is snap-connected with the breast pump body 4 .

[0111] According to the embodiments of the present disclosure, it should be noted that:

[0112] The breast pump body 4 can be any type of device that can provide suction for sucking milk and can store milk flowing out of the breast. For example, the breast pump body 4 can include a milk storage part for storing milk and a negative pressure generating component, and the negative pressure generating component can be arranged in the breast pump body 4 to form negative pressure. Of course, the negative pressure generating component can be a structure that generates negative pressure by means of an air pump or manual operation. The breast pump body 4 can also be an integrated structure with an integrated air pump or other controller or a split structure separated from the air pump or other controller.

[0113] The structure and description of the adsorption component can refer to the adsorption component in any of the above embodiments, and will not be repeated here.

[0114] According to the embodiments of the present disclosure, by arranging a flexible part to be sleeved on the breast pump body, the sealing performance of the connection between the adsorption piece and the breast pump body can be improved to avoid air leakage; by arranging a rigid part to support the flexible part, on the one hand, excessive deformation of the flexible part can be avoided, thereby ensuring the stability of the negative pressure environment of the breast pump during milk pumping, so that the breast pump can continuously and stably absorb milk; on the other hand, the flexible part can be supported by the rigid part to improve the convenience of connecting the adsorption piece to the breast pump body.
