[0002] A breast pump is a must-have item for breastfeeding women. It is mainly used to squeeze out the milk accumulated in the mammary glands. On the one hand, using a breast pump can dredge the mammary glands to prevent excess milk from accumulating in the mammary glands to form lumps or inflammation. On the other hand, it can extract and store excess milk to facilitate breastfeeding for babies who cannot suck milk. Common breast pumps use negative pressure to absorb breast milk from the breasts. The mother feels less discomfort during the absorption process, which reduces the problem of milk swelling. At the same time, the absorbed milk can be stored for easy feeding.

[0003] During the milk extraction operation, the negative pressure mechanism needs to be activated to draw air and generate suction. When the breast shield is in close contact with the female breast, a sealed negative pressure space is formed. The breast shield acts on the female breast to suck out the milk. The milk enters the drainage cavity from the milk suction channel of the breast shield fitting cavity and flows out from the milk outlet to the collection container for collection. The breast shield is generally made of soft and flexible materials, which can reduce discomfort when the breast shield is in close contact with the breast. However, the breast shield connected to the breast pump is not easy to clean.

[0028] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0029] like Figures 1 to 9 A breast pump shown includes a breast shield 1, a main unit 2, and a collection container 3 connected to the breast shield 1, and also includes a support member 4 connected between the breast shield 1 and the main unit 2, the support member 4 is connected to the outside of the breast shield 1 and abuts against the main unit 2, the support member 4 is provided with a connecting end 6, the breast shield 1 is provided with a mating end 7 matingly connected to the connecting end 6, the connecting end 6 and the mating end 7 are mated to make the support member 4 detachably connected to the breast shield 1. The utility model forms a supporting effect by connecting the support member to the outside of the breast shield, and at the same time, the support member abuts against the main unit on the outside of the breast shield, so that good sealing can be formed. The arrangement of the connecting end and the mating end makes it easy for the support member to be disassembled and connected with the breast shield, and the user can more easily separate the breast shield for cleaning. When reassembling, the structure of the mating end and the connecting end can ensure that the sealing of the support member and the breast shield is not affected when they are reconnected, so as to maintain the milk suction effect to meet the use requirements.

[0030] Specifically, a support piece is added between the breast shield and the main unit, and the support piece is located on the outside of the breast shield and in direct contact with the main unit, thereby playing the role of stable connection and support. When the breast shield needs to be cleaned, the user can easily separate the breast shield from the support piece, and since the direct contact surface between the support piece and the main unit does not change, even if the breast shield is removed, it will not affect the overall sealing of the breast pump. After cleaning, the breast shield is reconnected to the support piece. Due to the unique design of the mating end and the connecting end, it is ensured that the sealing of the two after being combined will not be reduced due to disassembly, thereby ensuring the sealing between the breast shield and the main unit, thereby maintaining an efficient milk suction effect, and greatly improving the user experience.

[0031] Furthermore, as a preferred embodiment of the present invention but not a limitation, the detachable design of the support member and the breast shield also facilitates the maintenance and repair of the breast pump, because the user can replace worn or damaged parts individually without having to replace the entire breast pump, thereby extending the service life of the breast pump.

[0032] Optionally, in some embodiments, the matching mode of the connection end and the matching end is not limited to mortise and tenon connection, groove connection, snap connection, threaded connection, magnetic connection, etc. By tightly connecting the connection end and the matching end, it can ensure that the connection between the breast shield and the host through the support member is more stable, and the support member can provide better support effect and sealing performance during use.

[0033] Optionally, in some embodiments, the breast shield is made of silicone material, and the supporting component can be made of a plastic material with a certain hardness and toughness, such as polyamide PA, polypropylene PP, silicone rubber, polyphenylene sulfone resin PPSU, thermoplastic elastomer TPE, etc.

[0034] like Figures 2 to 9 In the breast pump shown, the connection end 6 includes a support member engaging portion 60 disposed inside the support member 4, and the mating end 7 includes a breast shield limiting portion 70 located outside the breast shield 1, and the breast shield 1 and the support member 4 are both elastic. Further, as a preferred embodiment of the utility model but not a limitation, the support member engaging portion can ensure that the support member can be correctly engaged with the breast shield limiting portion during connection, and can be mutually interlocked during assembly to form a tight connection, so that even if a certain pulling force is generated during the milk pumping process, the breast shield will not easily fall off, thereby ensuring the continuity and efficiency of the milk pumping process. The breast shield limiting portion is outside the breast shield, and the breast shield limiting portion and the support member engaging portion can limit the movement of the breast shield on the support member, provide a positioning function during connection, and ensure the correct alignment and sealing between the support member and the breast shield. The elasticity of the breast shield and the support also makes disassembly relatively easy. The user can gently pull or press the breast shield limit portion with his hands to remove the breast shield from the support engagement portion for cleaning and disinfection.

[0035] In addition, the breast shield and the support are elastic and can produce a certain elastic deformation when connected, so that they can better adapt and be fixed together, enhancing the firmness and sealing of the connection, and can effectively solve the sealing problems that may occur when the breast shield is reassembled, while ensuring the stability of the connection, thereby improving the reliability and user experience of the breast pump.

[0036] Furthermore, the use of elastic materials also increases the comfort of the user during use. The elasticity of the breast shield can make it better fit the shape of the breast, reducing the discomfort during the milk extraction process. At the same time, the elasticity of the support and the breast shield helps to provide a certain buffering effect during the disassembly and assembly process, reducing the impact or pressure that may be generated during use, and reducing the risk of damage caused by improper operation.

[0037] Optionally, in some embodiments, the engaging portion of the support member may be configured as a protrusion, a depression, a slot or the like, and the limiting portion of the breast shield may be configured as a block, a protrusion, a depression or the like that cooperates with the engaging portion of the support member.

[0038] Optionally, in some embodiments, the engaging portion of the support member may be configured as a cylinder, and the limiting portion of the breast shield may be configured as a hole that cooperates with the cylinder. Such a design can simplify the structure, reduce the defect rate, and also facilitate assembly operations.

[0039] Optionally, in some embodiments, the hardness of the support member is greater than the hardness of the breast shield, so that the support assembly can provide a more stable support effect.

[0040] like Figures 2 to 9 A breast pump is shown, wherein the breast shield 1 comprises a breast shield fitting end 12, a breast shield connecting end 14 connected to the breast shield fitting end 12, the support member 4 is provided with a support member opening 41 for the breast shield connecting end 14 to extend into, and a support member cavity 42 communicated with the support member opening 41, the support member clamping portion 60 is located in the support member cavity 42 and is convex, and the breast shield limiting portion 70 comprises a groove arranged outside the breast shield connecting end 14 and matched with the support member clamping portion 60. Specifically, the breast shield fitting end can be set to an arc structure matching the shape of the breast, so as to fit the breast, the breast shield fitting end contacts the breast and forms a sealed negative pressure space to achieve the purpose of sucking milk. Specifically, the breast shield is set in a trumpet shape, and the outer diameter of the breast shield fitting end tends to gradually decrease towards the breast shield connecting end.

[0041] Further, as a preferred embodiment of the present invention but not limiting, the breast shield connection end can be set in a trumpet shape or a cylindrical shape. Optionally, in some embodiments, the minimum outer diameter of the breast shield is located at the breast shield connection end, which can reduce the space for contraction and expansion of the breast shield connection end, save space, and can squeeze the breast shield connection end through appropriate negative pressure so that milk is drawn out from the breast shield fitting end to the breast shield connection end, further improving the smoothness of breast pumping.

[0042] Further, as a preferred embodiment of the present invention but not a limitation, the opening of the support member provides a space for the breast shield connection end to enter, so that the user can easily insert the breast shield connection end into the support member cavity to achieve quick assembly. The support member cavity provides an installation space for the breast shield connection end, and its internal dimensions match the breast shield connection end to ensure the stability of the connection, while the convex design of the support member clamping portion can better cooperate with the groove of the breast shield limiting portion to ensure the stability and sealing of the connection. The support member clamping portion is located in the support member cavity, and the setting of the support member cavity allows the breast shield connection end to extend therein and engage with the support member clamping portion, so that the support member and the breast shield are more tightly connected, while ensuring the stability and support effect of the support member.

[0043] Optionally, in some embodiments, the protrusions of the support member engaging portion may be in the form of multiple blocks or dots, or may be in the form of a ring arranged along the outer circumference of the support member, and the breast shield limiting portion is a groove structure that matches the number and shape of the support member engaging portion.

[0044] Of course, the support member engaging portion 60 may be located in the support member cavity 42 and in a groove shape, and the breast shield limiting portion 70 includes a protrusion disposed on the outside of the breast shield connecting end 14 and cooperating with the support member engaging portion 60 .

[0045] like Figures 2 to 9 In the breast pump shown, the breast shield stopper 70 includes a protrusion disposed outside the breast shield connection end 14 and matched with the inner wall of the support cavity 42. Further, as a preferred embodiment of the present invention but not a limitation, such a configuration enables the breast shield to be correctly positioned and fixed when connected to the support, and the matching of the protrusion with the inner wall of the support cavity ensures the stability and sealing of the connection. In this way, the breast shield can be tightly combined with the support to prevent it from falling off or shifting due to vibration or negative pressure during use, thereby ensuring the effectiveness and performance stability of the breast pump during use.

[0046] Further, as a preferred embodiment of the present invention but not a limitation, such a configuration not only simplifies the operation process, but also improves the assembly efficiency. The breast shield can also be easily separated from the support member when disassembled, which is convenient for the user to clean and maintain. In addition, since the frontal protrusion of the breast shield limiter and the inner wall of the support member cavity are made of elastic materials, they can produce a certain deformation during the assembly process to adapt to breast shield connection ends of different sizes and shapes, thereby enhancing the versatility and flexibility of the design.

[0047] Optionally, in some embodiments, the protrusions of the breast shield limiting portion may be in the shape of a plurality of blocks or dots, or may be in the shape of a ring disposed along the outer circumference of the breast shield limiting portion.

[0048] Of course, the support member engaging portion 60 may be located in the support member cavity 42 and be in a convex shape, and the outer wall of the breast shield connecting end 14 may be engaged with the support member engaging portion 60 .

[0049] like Figures 2 to 7 A breast pump is shown, the support member 4 comprises a support member abutting end 401 abutting against the breast shield fitting end 12, and a support member supporting end 402 connected to the support member abutting end 401 and sleeved on the outside of the breast shield connecting end 14, the support member opening 41 is located on the support member abutting end 401, the support member cavity 42 passes through the support member supporting end 402, the breast shield 2 is provided with a first breast shield sealing end 141 abutting against the host 2 on the side close to the breast shield fitting end 12 and facing the host 2, and the support member abutting end 401 is provided with a support member avoiding end 48 for the first breast shield sealing end 141 to extend into and cooperate with sealing. Optionally, in some embodiments, the breast shield sealing end can not only be provided on the breast shield fitting end to fit on the host in a horizontal manner, but also be provided on the breast shield connecting end to fit on the host in a vertical manner.

[0050] The abutting end of the support piece abuts against the fitting end of the breast shield, so that the breast shield can be stably supported, ensuring the stability and sealing of the breast shield during use, thereby improving the use effect of the breast pump. The supporting end of the support piece is sleeved on the outer side of the connecting end of the breast shield, such a setting can support the periphery of the connecting end of the breast shield, the connection between the breast shield and the support piece is more stable, and the stability of the entire structure is increased. The cavity of the support piece passes through the supporting end of the support piece, providing space for the connecting end of the breast shield to extend into, and such a setting ensures the stability of the connection between the breast shield and the support piece.

[0051] Optionally, in some embodiments, the abutting end of the support member is horn-shaped, and the outer diameter of a side of the abutting end of the support member close to the breast shield fitting end is larger than the outer diameter of a side close to the supporting end of the support member.

[0052] Optionally, in some embodiments, the supporting end of the supporting member is arranged in a ring shape and sleeved on the outer side of the connecting end of the breast shield.

[0053] Further, as a preferred embodiment of the present invention but not a limitation, the first breast shield sealing end can be closely matched with the support member avoidance end, ensuring the sealing of the connection, which can effectively prevent breast milk from leaking out from the gap between the breast shield and the support member or from the gap between the support member and the main unit during the milk pumping process, thereby ensuring the milk pumping effect and user experience of the breast pump. It can also prevent gas from entering the breast pump from the gap between the breast shield and the main unit, affecting the effect of its negative pressure milk pumping.

[0054] Optionally, in some embodiments, the support member avoidance end is in the shape of a hole, and the first breast shield sealing end is in the shape of a protrusion. The support member avoidance end can form a positioning function, which not only provides a space for the first breast shield sealing end to extend into, so that the first breast shield sealing end can fit with the host, but also further enhances the sealing between the breast shield and the support member through the cooperation between the first breast shield sealing end and the support member avoidance end. This design allows the breast shield to be more stably fixed on the support member after assembly, reducing the risk of falling off or shifting due to vibration or improper operation during use.

[0055] like Figures 2 to 7 In the breast pump shown, the breast shield connection end 14 is provided with a second breast shield sealing end 142 on the side away from the breast shield fitting end 12 and facing the main unit 2, the main unit 2 is provided with a main unit sealing end 23 matched with the second breast shield sealing end 142, and a second deformation gap 143 is provided between the second breast shield sealing end 142 and the breast shield connection end 14. Further, as a preferred embodiment of the utility model but not a limitation, the first breast shield sealing end and the main unit, and the second breast shield sealing end and the main unit sealing end cooperate to form an effective sealing interface, thereby avoiding air leakage during the milk pumping process, and the second deformation gap can allow slight adjustment and adaptation between the components when the breast shield and the main unit are assembled, so that the breast shield can still ensure a tight connection without affecting the sealing performance after disassembly and reassembly.

[0056] Specifically, the second breast shield sealing end is trumpet-shaped, and the outer diameter of the side close to the breast shield fitting end is smaller than the outer diameter of the side away from the breast shield fitting end, so that the outer diameter difference between the two sides of the trumpet-shaped second breast shield sealing end forms a second deformation gap.

[0057] like Figures 4 to 9 A breast pump is shown, wherein the host 2 is provided with an air pump assembly 24 and a cavity 25 connected to the air pump assembly 24, one end of the breast shield connection end 14 extends into the cavity 25, the breast shield connection end 14 is provided with a breast shield connection end inner cavity 144, the breast shield connection end inner cavity 144 is provided with a plurality of deformation grooves 1441, and the breast shield 1 also includes a first deformation gap 15, the first deformation gap 15 is located between the breast shield fitting end 12 and the breast shield connection end 14, or located on the breast shield fitting end 12. Further, as a preferred embodiment of the utility model but not limited thereto, the air pump assembly provided inside the host can generate negative pressure, thereby simulating the sucking action of a baby to help the mother suck out breast milk. The cavity connected to the air pump assembly ensures that the negative pressure can be evenly and effectively transmitted to the breast shield, so that when the breast shield is tightly fitted to the breast, an effective negative pressure space is formed to improve the milk suction efficiency.

[0058] Specifically, one end of the breast shield connection end extends into the cavity, which can make the connection between the breast shield and the host more stable, and also ensure the smoothness of negative pressure transmission. By extending the breast shield connection end into the cavity, the risk of leakage at the connection can be effectively reduced, and the overall sealing performance can be improved. The elasticity and adaptability of the breast shield are increased by multiple deformation grooves. When pressure acts on the breast shield connection end, the presence of the deformation groove makes it easier for the breast shield to deform to a certain extent when subjected to negative pressure, which not only improves the comfort of milk suction, but also helps to improve the milk suction effect.

[0059] Specifically, the first deformation gap is located on the fitting end of the breast shield. The setting of the first deformation gap helps to reduce the problem of breast shield deflation caused by breast shape change or improper operation, while ensuring the sealing effect and further improving the stability and reliability of the breast pump. When the breast presses the fitting end of the breast shield, the fitting end of the breast shield can adapt to the shape of the breast and get closer to the breast to form negative pressure.

[0060] Specifically, the first deformation gap between the breast shield fitting end and the breast shield connecting end provides a certain amount of expansion and contraction space for the breast shield. This enables the breast shield to adapt to the shape changes of the breast more naturally and flexibly when fitting the breast. The breast shield connecting end can support the fitting end of the breast shield to prevent the fitting end of the breast shield from shifting and deflation.

[0061] The breast shield connection end is tightly connected to the main unit, and the stability and sealing of the connection are ensured through a plurality of deformation grooves and a first deformation gap.

[0062] like Figures 2 to 9 A breast pump is shown, wherein the breast shield 1 is provided with a milk suction channel 11, a breast shield drainage port 13 connected to the milk suction channel 11, the support member 4 is provided with a support member connection port 43 connected to the breast shield drainage port 13, a drainage channel 44 located between the support member connection port 43 and the collection container 3, and an opening 45 for balancing the air pressure between the collection container 3 and the outside. Further, as a preferred embodiment of the utility model but not a limitation, a smooth and coordinated milk flow system is formed by the milk suction channel, the breast shield drainage port, the support member connection port and the drainage channel to improve the efficiency and convenience of the breast pump. It helps to meet the user's demand for milk collection and provide a better user experience.

[0063] Specifically, when the breast is attached to the fitting end of the breast shield, the setting of the milk suction channel allows the milk to smoothly pass through the breast shield into the collection container. The drainage channel is located in the support member and is connected to the collection container. The setting of the drainage channel can prevent the milk from contacting the outside world when entering the collection container, ensuring the normal operation and hygiene of the breast pump. The breast shield drainage port is located in the breast shield, and the support member connection port is located in the support member. The two form a connection between the milk suction channel and the drainage channel, realizing rapid communication with the breast shield and the collection container. Such a setting can allow the milk to flow smoothly from the milk suction channel to the drainage channel, and finally be collected in the collection container, realizing the collection and discharge of the milk, and improving the convenience of use.

[0064] Optionally, in some embodiments, the milk suction channel and the liquid discharge channel are in a pipe-like structure to facilitate the transmission of milk. The milk suction channel and the liquid discharge channel can be straight or curved.

[0065] Optionally, in some embodiments, the opening can balance the air pressure inside and outside the container, which helps to discharge milk smoothly and maintain the stability and efficiency of the breast pump.

[0066] like Figures 2 to 5 In the breast pump shown, the main unit 2 is provided with a main unit opening 20 for the breast shield 1 to extend into, a main unit connecting hole 21, and a clamping member 22 extending into the main unit connecting hole 21, and the support member 4 is provided with a support member connecting groove 46, and the clamping member 22 cooperates with the support member connecting groove 46 to fix the support member 4 on the main unit 2. Further, as a preferred embodiment of the present utility model but not limited thereto, the support member connecting groove is located on a side of the support member away from the breast shield fitting end.

[0067] Optionally, in some embodiments, the host may be made of plastic material.

[0068] Optionally, in some embodiments, the host connection hole can be set to a circular, elliptical or other shape to facilitate the passage and connection of the clamping member.

[0069] Optionally, in some embodiments, the clamping member may be an elastic protrusion. The clamping member may be fixed to the host connection hole by rotation, insertion, etc. When the support member is inserted into the host opening and moves toward the cavity, the support member connection groove and the clamping member are matched and connected, thereby achieving a tight connection between the support member and the host.

[0070] Optionally, in some embodiments, the supporting member connecting groove may be configured as a hole-shaped structure matching the clamping member to facilitate the connection of the clamping member.

[0071] Optionally, in some embodiments, the support member connecting groove can be configured to have grooves of different depths. When the support member is mounted on the mainframe, the side of the support member connecting groove away from the breast shield fitting end is a deeper groove, thereby facilitating the sliding of the clamping member on the support member connecting groove. When the support member reaches a specified position, the side of the support member connecting groove close to the breast shield fitting end is a shallower groove. The user continues to push with force to clamp the clamping member and the support member connecting groove, thereby tightly connecting the support member to the mainframe, ensuring that the position of the support member on the mainframe is fixed to prevent displacement or loosening during use.

[0072] like Figures 4 to 7 In the breast pump shown, the outer side wall of the support member 4 is provided with a support member connecting end 47, and the inner side wall of the collection container 3 is provided with a collection container fastening end 31 that cooperates with the support member connecting end 47;

[0073] The collection container fastening end 31 is provided with a fastening clamping portion 311 protruding toward the support member connecting end 47, and the support member connecting end 47 includes a support member avoidance groove 471 for the fastening clamping portion 311 to extend into, and a support member fixing groove 472 that is connected to the support member avoidance groove 471 and is used to fix the fastening clamping portion 311. Further, as a preferred embodiment of the present utility model but not a limitation, by cooperating with the support member connecting end and the collection container fastening end, the support member is fixedly connected to the collection container, thereby avoiding the collection container from becoming loose or unstable during use.

[0074] Optionally, the matching mode between the supporting member connection end and the collecting container fastening end is not limited to mortise and tenon connection, groove connection, snap connection, threaded connection, magnetic connection, or other reliable connection modes.

[0075] Furthermore, as a preferred embodiment of the present utility model but not a limitation, the support member avoidance groove can ensure that the fastening engaging part can be smoothly inserted and provide space for the fastening engaging part to move and adjust its position. The support member fixing groove is connected to the support member avoidance groove, and the support member fixing groove is used to fix the position of the fastening engaging part. The support member fixing groove ensures that the fastening engaging part can be stably fixed in an appropriate position by contacting and limiting the movement of the fastening engaging part. Through the coordinated design of the fastening engaging part, the support member avoidance groove and the support member fixing groove, a firm connection and fixation between the fastening end of the collection container and the support member is achieved.
