Description

Technical Field

[0001] This utility model relates to the technical field of breast pumps, and in particular to a breast pump. Background Technology

[0002] A breast pump is a device used to help mothers extract milk from their breasts and is widely used by breastfeeding mothers. Its main function is to assist mothers in storing milk when direct breastfeeding is inconvenient, or to empty the breasts when there is excessive milk production, thus preventing breast engorgement. In addition, breast pumps can help mothers maintain milk production, especially when they need to be away from their babies for extended periods, ensuring that the baby continues to receive the nutrition of breast milk.

[0003] However, a common problem with existing breast pumps on the market is that the sealing ring is usually set independently and is snapped into the breast pump by a slot. In daily life, the breast pump needs to be disassembled and cleaned frequently, and the sealing ring is also removed to facilitate cleaning the gaps. However, the sealing ring usually has a small outer diameter, and when users reassemble the breast pump, the sealing ring is easy to install crookedly. Users have difficulty installing the sealing ring accurately, which makes the breast pump prone to milk leakage and results in a poor user experience.

[0004] In addition, with existing breast pumps, users often cannot visually observe the flow of milk during use, which reduces the user experience and makes it difficult for users to judge whether the milk pumping process is going smoothly.

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

[0006] This invention addresses the problems mentioned above, such as the sealing ring in existing breast pumps being easily installed crookedly, making it difficult for users to accurately install the sealing ring, leading to easy milk leakage, and the inability for users to visually observe the milk flow during use, making it difficult to judge whether the milk pumping process is going smoothly, thus reducing the user experience.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0024] like Figures 1 to 10As shown, this utility model provides a breast pump, including a milk storage container 1, a milk suction component 2, and a negative pressure assembly 5. The milk storage container 1 has an inner cavity 11 and a transparent part that makes the inner cavity 11 visible. A milk suction channel 3 communicating with the inner cavity 11 is provided between the milk suction component 2 and the milk storage container 1. An integrally formed sealing part 4 is provided on the milk storage container 1 or the milk suction component 2, and the milk storage container 1 and the milk suction component 2 are sealed together by the sealing part 4. The negative pressure assembly 5 is detachably connected to the milk storage container 1.

[0025] In this invention, by providing an integrally formed sealing part 4 on the milk storage container 1 or the breast pump 2, the user can directly assemble the breast pump 2 and the milk storage container 1 without the need for an additional sealing ring. This reduces the assembly difficulty of the breast pump, avoids incorrect or crooked installation, facilitates disassembly and cleaning, and optimizes the user experience. Furthermore, the sealing part 4 enables a detachable sealed connection between the milk storage container 1 and the breast pump 2, effectively sealing the assembly gap between them and preventing leakage from the inner cavity 11 of the milk storage container 1. This improves the sealing performance of the breast pump, ensures its normal operation, enhances pumping efficiency, and guarantees the hygienic storage of the milk. In addition, the milk storage container 1 has a transparent section that allows visualization of the inner cavity 11, enabling the user to directly observe the milk flow and adjust the breast pump accordingly, further optimizing the user experience.

[0026] In this embodiment, the inner cavity 11 is located in the milk storage container 1 and faces the breast pump 2. After assembly, the inner cavity 11 can be formed by the breast pump 2 and the milk storage container 1. The negative pressure component 5 and the breast pump 2 are respectively located on both sides of the milk storage container 1. The breast pump 2 can be worn on the human breast, allowing the breast to extend into the breast pumping channel 3. The negative pressure component 5 generates negative pressure in the breast pumping channel 3 to promote the output of breast milk. The breast milk can flow unidirectionally along the breast pumping channel 3 into the inner cavity 11 for storage.

[0027] Optionally, the milk storage container 1 is provided with a one-way valve 6 that is sealed and connected to the milk storage container 1. The one-way valve 6 enables one-way communication between the milk expression channel 3 and the inner cavity 11 to prevent backflow of breast milk in the inner cavity 11. Optionally, the one-way valve 6 can be a duckbill valve or similar commonly used in existing breast pumps, and this utility model does not impose a specific limitation.

[0028] In this embodiment, the transparent part can be located at the top of the milk storage container 1, or the upper part of the milk storage container 1 or the entire milk storage container 1 can be made of transparent material to form the transparent part. This utility model does not make specific limitations. Users can directly see the milk volume of the inner cavity 11 through the transparent part by looking down, thereby understanding the milk expression situation and making it easier for users to adjust the milk expression process.

[0029] Furthermore, such as Figure 5 and Figure 6 As shown, the milk storage container 1 has a first connecting portion 12 on the side facing the breast pump 2, and the breast pump 2 has a second connecting portion 21 that corresponds to and is connected to the first connecting portion 12. The sealing portion 4 includes a first sealing element 41, which is integrally formed on the first connecting portion 12 or the second connecting portion 21. The first sealing element 41 is used to seal the assembly gap between the first connecting portion 12 and the second connecting portion 21, and is made of a soft material. Specifically, the first sealing element 41 can be made of soft materials such as silicone or rubber, and the first sealing element 41 can be set on the first connecting portion 12 or the second connecting portion 21 through a rubber coating process to enhance the sealing performance of the breast pump. In addition, the first connecting portion 12 and the second connecting portion 21 adopt an interference fit assembly structure, which allows the milk storage container 1 and the breast pump 2 to be directly inserted and connected, making it convenient for users to disassemble and assemble the breast pump. After assembly, the first sealing element 41 can directly seal the assembly gap between the first connecting portion 12 and the second connecting portion 21, which helps to improve the sealing performance and reliability of the breast pump.

[0030] Further optional, such as Figure 5 and Figure 6 As shown, the first connecting portion 12 is formed at the periphery of the end facing the breast pump 2 in the milk storage container 1. The second connecting portion 21 can be configured as a mounting groove located on one side of the breast pump 2 and facing the first connecting portion 12. The first sealing member 41 can be integrally formed on the inner and / or outer side of the first connecting portion 12, or the first sealing member 41 can be integrally formed on the inner side of the second connecting portion 21. Furthermore, the inner and outer sides of the mounting groove are provided with opposing first positioning walls 211 and second positioning walls 212, which is beneficial for the accurate assembly of the breast pump 2 and the milk storage container 1, and improves the assembly stability and reliability of the breast pump, further optimizing the user experience. Alternatively, the first connecting portion 12 can also be configured as a slot, and the second connecting portion 21 can also be configured as a retaining ring adapted to the mounting groove. This utility model does not impose specific limitations.

[0031] In this embodiment, as Figure 5 and Figure 7As shown, the milk storage container 1 is provided with a receiving cavity 13 for accommodating the negative pressure component 5 and a partition 14 located between the receiving cavity 13 and the inner cavity 11. The receiving cavity 13 is connected to the milk suction channel 3. A third connecting part 141 extending toward the inner cavity 11 is provided on one side of the partition 14. A fourth connecting part 22 correspondingly connected to the third connecting part 141 is provided at one end of the milk suction component 2. The sealing part 4 includes a second sealing member 42, which is integrally formed on the third connecting part 141 or the fourth connecting part 22. The second sealing member 42 is made of soft material. Specifically, the second sealing element 42 can be made of soft materials such as silicone or rubber, and the second sealing element 42 can be set on the third connecting part 141 or the fourth connecting part 22 through a rubber coating process to enhance the sealing performance of the breast pump. In addition, the third connecting part 141 and the fourth connecting part 22 adopt an interference fit assembly structure, which allows the milk storage container 1 and the breast pump 2 to be directly inserted and connected, making it convenient for users to disassemble and assemble the breast pump. After assembly, the assembly gap between the third connecting part 141 and the fourth connecting part 22 can be directly sealed by the second sealing element 42, which helps to improve the sealing performance and reliability of the breast pump.

[0032] Further optional, such as Figure 7 As shown, one end of the partition 14 extends towards the inner cavity 11 to form the third connecting part 141. The end of the breast pump 2 forms a fourth connecting part 22 corresponding to the third connecting part 141. The fourth connecting part 22 can be inserted into the inner side of the third connecting part 141. The second sealing member 42 is integrally formed on the inner side of the third connecting part 141 or the outer side of the fourth connecting part 22. The second sealing member 42 seals the assembly gap between the third connecting part 141 and the fourth connecting part 22, thereby improving the connection stability and sealing between the breast pump 2 and the milk storage container 1, preventing leakage from the inner cavity 11 towards the receiving cavity 13, ensuring the normal operation of the breast pump, and improving milk pumping efficiency. Alternatively, the fourth connecting part 22 can be inserted into the outer side of the third connecting part 141, and the second sealing member 42 can be integrally formed on the outer side of the third connecting part 141 or the inner side of the fourth connecting part 22. This invention does not impose specific limitations.

[0033] Further optional, such as Figure 9 As shown, in the embodiment where the breast pump 2 is engaged with the inner side of the third connecting part 141, the inner diameter of the third connecting part 141 gradually increases from the negative pressure component 5 toward the breast pump 2, so that an assembly guide wall is formed on the inner side of the third connecting part 141. The fourth connecting part 22 can be guided to engage with the inner side of the third connecting part 141 through the assembly guide wall, so that the assembly between the breast pump 2 and the milk storage container 1 is smoother, and the situation where the breast pump 2 gets stuck and makes assembly difficult is avoided.

[0034] Furthermore, such as Figure 5 and Figure 8 As shown, the milk storage container 1 has a receiving cavity 13 on the side away from the first connecting part 12, and the receiving cavity 13 faces the negative pressure component 5. The receiving cavity 13 is connected to one side of the milk suction channel 3. The negative pressure component 5 can be assembled into the receiving cavity 13. The negative pressure component 5 can generate negative pressure in the milk suction channel 3, thereby simulating the sucking action of an infant and improving the milk suction efficiency. Further optionally, the receiving cavity 13 extends from the outer wall of the milk storage container 1 toward the inner cavity 11, and forms the partition 14 through the milk storage container 1 itself, so as to separate the inner cavity 11 and the receiving cavity 13, which facilitates the installation of the milk suction component 2 and the negative pressure component 5 in the milk storage container 1.

[0035] In this embodiment, as Figure 8 As shown, the milk storage container 1 is also provided with a fifth connecting part 142 for connecting the negative pressure component 5. The fifth connecting part 142 is located on the side of the partition 14 away from the third connecting part 141. The negative pressure component 5 is provided with an assembly structure that corresponds to and cooperates with the fifth connecting part 142, and the negative pressure component 5 can rotate relative to the fifth connecting part 142 through the assembly structure. Specifically, the two ends of the partition 14 are respectively provided with a third connecting part 141 for connecting the breast pump 2 and a fifth connecting part 142 for connecting the negative pressure component 5. The breast pump 2 and the negative pressure component 5 can be housed in the milk storage container 1, which helps to reduce the size of the breast pump, thereby improving the user's wearing comfort and further optimizing the user experience. Secondly, the negative pressure component 5 is connected to the fifth connecting part 142 by the assembly structure with an interference fit, which helps to simplify the assembly of the negative pressure component 5 and further facilitates the user's disassembly and assembly of the breast pump. At the same time, the negative pressure component 5 can rotate around the fifth connecting part 142 through the assembly structure, allowing the user to adjust the installation direction of the input end of the negative pressure component 5, thereby improving the connection flexibility between the negative pressure component 5 and the negative pressure source and further optimizing the user experience. Further optionally, the fifth connecting part 142 can be preferably an annular connecting part, so that the negative pressure component 5 can rotate around the fifth connecting part 142 through the assembly structure when subjected to external force, improving the smoothness of the rotation of the negative pressure component 5.

[0036] Furthermore, such as Figure 5 and Figure 8As shown, the negative pressure assembly 5 includes a main body 51 and a deformable member 52 connected to the main body 51. The main body 51 and the deformable member 52 enclose a negative pressure cavity 53. The main body 51 is provided with a suction channel 54 communicating with the negative pressure cavity 53. The deformable member 52 is located in the receiving cavity 13, and the pressure change inside the negative pressure cavity 53 can cause the deformable member 52 to undergo elastic deformation of expansion and contraction within the receiving cavity 13, thereby causing a change in pressure within the milk suction channel 3, realizing the action of the breast pump simulating a baby sucking milk. At the same time, part of the cavity in the receiving cavity 13 is shared with the milk suction channel 3, that is, the deformable member 52 can directly deform within the milk suction channel 3 to realize negative pressure changes within the milk suction channel 3, greatly shortening the path of negative pressure transmission within the milk suction channel 3, thereby improving milk suction efficiency. Further optionally, the suction channel 54 can be a suction port or suction connector provided on the main body 51. This utility model does not make a specific limitation. The suction channel 54 is used to connect an external negative pressure source, and the negative pressure is generated in the negative pressure chamber 53 through the external negative pressure source. In this embodiment, the negative pressure component 5 has a simple structure, which helps to reduce the size and weight of the breast pump and further improve the user's wearing comfort.

[0037] Furthermore, such as Figure 8 As shown, the assembly structure includes a clamping groove 521 located at one end of the deformable member 52 and facing the fifth connecting portion 142, and a support portion 511 located on the main body 51. The deformable member 52 is connected to the fifth connecting portion 142 through the clamping groove 521. The support portion 511 extends toward the deformable member 52 and is connected to the inner side of the deformable member 52. The deformable member 52 is fixed by the support portion 511 and the fifth connecting portion 142. The deformable member 52 is made of soft material. Specifically, the main body 51 has an assembly surface located outside the fifth connecting part 142. During assembly, the clamping groove 521 is connected to the fifth connecting part 142 in a corresponding manner, which helps to reduce the assembly difficulty of the negative pressure component 5 and further facilitates the user's disassembly and assembly of the breast pump. At the same time, the assembly surface and the milk storage container 1 can clamp the deformable part 52 in the horizontal direction, preventing the negative pressure component 5 from separating from the milk storage container 1 due to changes in internal negative pressure during use, thus ensuring the normal use of the breast pump. Secondly, the deformable part 52 can be made of soft materials such as silicone or rubber to ensure the elastic deformation of the deformable part 52, thereby realizing the negative pressure change of the negative pressure chamber 53 and the milk suction channel 3. After assembly, the fifth connecting part 142 and the support part 511 can clamp and fix the deformable part 52 in the vertical direction, thereby improving the connection stability and sealing between the negative pressure component 5 and the milk storage container 1, and ensuring the normal use of the negative pressure component 5.

[0038] Further optional, such as Figure 8 As shown, the deformable member 52 is also provided with an outer side wall 522. The outer side wall 522 and the deformable member 52 surround each other to form a clamping groove 521 facing the fifth connecting part 142. The outer side wall 522 is integrally formed with the deformable member 52. The inner side of the outer side wall 522 is provided with a barb portion 523 facing the deformable member 52. The outer side of the barb portion 523 is provided with an inclined guide portion 524. The guide portion 524 is inclined outside the barb portion 523 and faces the fifth connecting part 142. The guide portion 524 guides the outer side wall 522 to engage with the outer periphery of the fifth connecting part 142. During assembly, the deformable part 52 can first be fitted onto the outer periphery of the support part 511. The support part 511 fixes the shape of the deformable part 52 from the inside, preventing deformation of the deformable part 52 during assembly. Subsequently, the negative pressure assembly 5 is engaged with the fifth connecting part 142 through the clamping groove 521 in the deformable part 52, thereby achieving a detachable connection between the negative pressure assembly 5 and the milk storage container 1. At the same time, the negative pressure assembly 5 can rotate around the fifth connecting part 142 through the clamping groove 521 when subjected to external force. During rotation, the guide part 524 is deformed by the push of the fifth connecting part 142 to guide the outer wall 522 to be screwed onto the outer periphery of the fifth connecting part 142, and through... The fifth connecting part 142 is clamped by the barb portion 523 and the body of the deformable part 52, thereby realizing the assembly connection between the deformable part 52 and the fifth connecting part 142. Moreover, since the deformable part 52 is made of soft material, it has a certain elastic pre-tightening force. During the relative rotation of the deformable part 52 and the fifth connecting part 142, the deformable part 52 can be squeezed by both the body 51 and the fifth connecting part 142 to further clamp and fix it, thereby making the deformable part 52 close the assembly gap between the body 51 and the fifth connecting part 142. This greatly improves the connection stability and sealing between the negative pressure component 5 and the milk storage container 1, thereby improving the reliability of the breast pump.

[0039] Further optional, such as Figure 8As shown, the deformable member 52 has a limiting part 525 facing the fifth connecting part 142 and a protruding ring 526 facing the supporting part 511. The fifth connecting part 142 has a mating part 143 adapted to the limiting part 525, and the supporting part 511 abuts against the protruding ring 526. Specifically, the limiting part 525 is provided on the outer wall surface of the deformable member 52 and faces the clamping groove 521. The mating part 143 is provided on the inner wall of the fifth connecting part 142. After the deformable member 52 is connected to the outside of the fifth connecting part 142, the limiting part 525 and the mating part 143 also cooperate accordingly. The mating part 143 restricts the deformable member 52 from leaving the receiving cavity 13, thereby improving the connection stability between the deformable member 52 and the milk storage container 1 and preventing the deformable member 52 from being subjected to negative pressure inside the breast pump. The deformation component 52 is designed to prevent it from dislodging due to changes in pressure, thus ensuring the normal operation of the breast pump. On the other hand, the inner wall of the deformation component 52 is provided with a protruding ring 526 facing the support portion 511. After the deformation component 52 is connected to the support portion 511, the support portion 511 can further squeeze the protruding ring 526, thereby squeezing the deformation component 52, strengthening the connection stability and sealing between the deformation component 52 and the main body 51, and preventing the main body 51 and the deformation component 52 from easily separating due to changes in negative pressure, further ensuring the normal operation of the negative pressure component 5.

[0040] Further optional, such as Figure 2 and Figure 9 As shown, the milk storage container 1 is also provided with a relief groove 15 on the outer periphery of the fifth connecting part 142 and a disassembly groove 16 communicating with the relief groove 15, and the negative pressure component 5 is provided with the disassembly groove 16 on at least one side. Specifically, the fifth connecting part 142 is located inside the milk storage container 1, which helps to reduce the volume of the breast pump. Correspondingly, a clearance groove 15 is also provided on the outer periphery of the fifth connecting part 142. The width of the clearance groove 15 can be greater than the thickness of the outer wall 522 of the clamping groove 521 in the deformable part 52. During the assembly process, the deformable part 52 is rotated around the fifth connecting part 142 by external force, and the outer wall 522 is fixed to the outer periphery of the fifth connecting part 142 by the guide part 524, and the outer wall 522 is located in the clearance groove 15. On the other hand, in order to facilitate the user to disassemble the negative pressure component 5, a disassembly groove 16 is provided on the milk storage container 1. The disassembly groove 16 is recessed from the outer wall surface of the milk storage container 1 toward the inner cavity 11. During disassembly, the user's fingers are inserted through the disassembly groove 16 to the side of the negative pressure component 5 and the negative pressure component 5 is removed from the milk storage container 1 as a whole. Furthermore, the disassembly groove 16 is provided on both sides of the negative pressure component 5.

[0041] In other alternative embodiments, such as Figure 1As shown, the breast pump 2 has an integrally formed suction cup 20 on its inner side. The breast pump channel 3 extends to the inner side of the suction cup 20 and communicates with the outside. The suction cup 20 is made of a soft material. Specifically, one end of the breast pump 2 is configured as a flared cover for conforming to the human breast. The suction cup 20 is at least integrally formed on the inner side of the flared cover to improve the user's wearing comfort. At the same time, the suction cup 20 can be made of soft materials such as silicone or rubber, which can improve the fit of the breast pump 2 to the human body, allowing the breast pump to be worn stably on the user and preventing the breast pump from falling off. At the same time, the suction cup 20 can improve the seal between the breast pump 2 and the human breast, preventing milk backflow and leakage.

[0042] In practical applications, when a breast pump is needed, the breast is placed against the suction cup 20 of the breast pump component 2, and the external negative pressure source connected to the negative pressure assembly 5 is activated to generate negative pressure in the negative pressure chamber 53. The elastic deformation of the deformable component 52 generates negative pressure in the breast pumping channel 3. Under negative pressure, the suction cup 20 can better fit the breast, and the negative pressure environment in the breast pumping channel 3 promotes the flow of breast milk. The breast milk can flow along the breast pumping channel 3 through the one-way flow assembly to the inner cavity 11 for storage.

[0043] In other alternative embodiments, such as Figure 1 As shown, the breast pump 2 is provided with a fixing part 23, and the milk storage container 1 is provided with a snap-fit ​​part 17 corresponding to the fixing part 23. The fixing part 23 is provided with a snap-fit ​​opening 231. The fixing part 23 is snapped onto the outside of the snap-fit ​​part 17 through the snap-fit ​​opening 231, and the snap-fit ​​part 17 and the breast pump 2 have a liquid outlet 171 communicating with the inner cavity 11. Specifically, the fixing part 23 extends from the outer edge of the breast pump 2 toward the milk storage container 1, the latch 231 extends longitudinally through the fixing part 23, and the latching part 17 extends upward from the top of the milk storage container 1. The latching part 17 can latch onto the inner side of the fixing part 23 to facilitate the detachable fixing of the breast pump 2 to the milk storage container 1. The connection structure between the latching part 17 and the fixing part 23 is simple, making it easy for users to assemble and disassemble the breast pump 2. The latching part 17 and the breast pump 2 together form an outlet 171 that communicates with the inner cavity 11. In practical applications, the breast pump can be inverted and the breast milk in the inner cavity 11 can be poured out through the outlet 171 for the baby to consume.

[0044] Alternatively, the snap-fit ​​portion 17 extends along the contour of the liquid outlet 171 to improve the connection stability between the milk suction member 2 and the milk storage container 1.

[0045] During assembly, the breast pump 2 can first be engaged with the locking part 17 via the fixing part 23 to position the breast pump 2, and then be connected via the second connecting part 21 and the fourth connecting part 22 corresponding to the first connecting part 12 and the third connecting part 141 respectively, so as to realize the detachable connection between the breast pump 2 and the milk storage container 1. The breast pump is easy to assemble and disassemble, and can be adapted to frequent disassembly and cleaning in daily use, which greatly optimizes the user experience.

[0046] In other alternative embodiments, such as Figure 10 As shown, the bottom of the milk storage container 1 is provided with a placement base 18, and the breast pump 2 is also provided with at least one outwardly extending extension 24, which is located on one side of the placement base 18. Specifically, the extension 24 is provided on the outer side of the breast pump 2, which can provide a force fulcrum for the user to disassemble the breast pump assembly, making it easier for the user to disassemble the negative pressure assembly 5 and the milk storage container 1. The bottom of the milk storage container 1 is provided with a placement base 18. Optionally, the placement base 18 can be provided with at least two legs or the annular extension 24. This utility model does not make a specific limitation. The placement base 18 allows the milk storage container 1 to be placed stably on the table, effectively preventing the breast pump from tipping over and causing milk to leak from the outlet 171. This design not only improves the convenience of using the breast pump, but also enhances its safety during use.

[0047] Alternatively, the extension 24 is located at the bottom of the breast pump 2 and corresponds to the placement seat 18, which can further improve the stability of the breast pump placement, while simplifying the structure of the placement seat 18 and reducing production costs.

[0048] Optionally, the milk storage container 1 can be bowl-shaped, which can further improve the user's wearing comfort and increase the capacity of the inner cavity 11, making it easier for the baby to feed.

[0049] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. 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.
