[0002] A breast pump is a tool used to express breast milk that has accumulated in the mammary glands. It uses an internal vacuum negative pressure pump to change the internal air pressure, i.e., to perform a cyclical suction and release operation, to simulate the action of a baby sucking breast milk and achieve the purpose of milk expression. In order to meet the needs of users to perform breast pumping discreetly in public places, wearable breast pumps that can be inserted into a bra have emerged.
[0003] Because breastfeeding mothers use breast pumps frequently, they need to disassemble the pump parts often for cleaning and sterilization, and reassemble the pump for use. However, the front and back shells of existing wearable breast pumps are not easy to open, making disassembly and assembly difficult, time-consuming, and laborious. This makes it inconvenient to assemble for pumping and disassemble for cleaning, resulting in a poor user experience.
[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0039] Example 1:
[0040] like Figure 1 As shown in Figure 4, this utility model provides an easily detachable wearable breast pump device, including a breast bowl body 1, a milk storage chamber 13 disposed within the breast bowl body 1, a milk pouring port 14 disposed within the breast bowl body 1 and communicating with the milk storage chamber 13, and an operating part 15 disposed outside the breast bowl body 1. The breast bowl body 1 includes a front shell 11 and a rear shell 12. The front shell 11 has a first snap-fit part 112, and the rear shell 12 has a second snap-fit part 122 corresponding to the first snap-fit part 112. The front shell 11 and the rear shell 12 are detachably connected by the corresponding snap-fit of the first snap-fit part 112 and the second snap-fit part 122. The operating part 15 is used to drive the breast pump... The front shell 11 and the rear shell 12 of the milk bowl are separate. In this embodiment, the front shell 11 and the rear shell 12 of the milk bowl are arranged axially back and forth, and are directly plugged and unplugged along the axial direction through the first snap-fit part 112 and the second snap-fit part 122, thereby realizing the detachable connection of the front shell 11 and the rear shell 12 of the milk bowl. This reduces the difficulty of disassembling and assembling the front shell 11 and the rear shell, making it easier for users to disassemble and assemble the milk bowl body 1. This allows the wearable breast pump to adapt to the frequent cleaning and assembly of the milk bowl body 1, improving the user experience. In addition, the milk bowl body 1 is provided with an operating part 15 on the outside, which helps to provide a gripping fulcrum for users to manually disassemble the milk bowl body 1, making it convenient for users to disassemble and assemble the front shell 11 and the rear shell 12 of the milk bowl.
[0041] In practical applications, when assembling the milk bowl body 1, the user can directly apply force to the front shell 11 and the rear shell 12 of the milk bowl, causing them to move closer together axially. The front shell 11 and the rear shell 12 are then engaged together via the first engaging part 112 and the second engaging part 122. After assembly, the front shell 11 and the rear shell 12 enclose the milk storage cavity 13. The milk pouring port 14 is located at the top of the milk bowl body 1 and communicates with the milk storage cavity 13, allowing the user to pour milk through... The milk storage chamber 13 holds breast milk, and the breast milk is poured out directly through the milk outlet 14. When disassembling the main body of the milk bowl 1, the user can apply force to the front shell 11 and the rear shell 12 of the milk bowl through the operating part 15, so that the front shell 11 and the rear shell 12 of the milk bowl move away from each other along the axial direction. At this time, the first locking part 112 and the second locking part 122 are subjected to opposite forces and separate relative to each other, thereby disassembling the front shell 11 and the rear shell 12 of the milk bowl, which is beneficial for the user to clean the inside of the front shell 11 and the rear shell 12 of the milk bowl.
[0042] Specifically, such as Figure 3 and Figure 4As shown, the front shell 11 of the milk bowl is provided with a first connecting wall 111, and a first snap-fit part 112 is provided in the first connecting wall 111. The rear shell 12 of the milk bowl is provided with a second connecting wall 121 corresponding to the first connecting wall 111, and a second snap-fit part 122 is provided in the second connecting wall 121. One snap-fit part of the first snap-fit part 112 and the second snap-fit part 122 is a snap-fit block 102, and the other snap-fit part is a corresponding snap-fit groove 101. In this embodiment, the first connecting wall 111 and the second connecting wall 121 are set as annular walls that can cooperate with each other. The first snap-fit part 112 and the second snap-fit part 122 are provided in the opposing surfaces between the first connecting wall 111 and the second connecting wall 121 to improve the connection tightness of the first snap-fit part 112 and the second snap-fit part 122, making the assembly between the front shell 11 of the milk bowl and the rear shell 12 of the milk bowl more compact. This helps to reduce the volume and thickness of the wearable breast pump, improve the portability of the breast pump, and enhance the user's experience. The first connecting wall 111 can be sleeved on the outside of the second connecting wall 121, with the first snap-fit part 112 located inside the first connecting wall 111 and the second snap-fit part 122 located outside the second connecting wall 121 and corresponding to the first snap-fit part 112. Alternatively, the second connecting wall 121 can be sleeved on the outside of the first connecting wall 111, with the first snap-fit part 112 located outside the first connecting wall 111 and the second snap-fit part 122 located inside the second connecting wall 121 and corresponding to the first snap-fit part 112. This utility model does not impose specific limitations. In addition, the first snap-fit part 112 and the second snap-fit part 122 are configured as a block-slot snap-fit structure that cooperates with each other. The structure is simple and easy to implement. Optionally, the first snap-fit part 112 can be configured as a snap-fit block 102 or a snap-fit slot 101, and correspondingly, the second snap-fit part 122 can be configured as a corresponding snap-fit slot 101 or a snap-fit block 102. This utility model does not impose specific limitations.
[0043] Furthermore, such as Figure 6 and Figure 9As shown, the locking block 102 is provided with a first guide wall 1021 and a second guide wall 1022 on both sides. The first guide wall 1021 is located on the front side of the locking block 102 and faces the locking groove 101. The second guide wall 1022 is located on the rear side of the locking block 102 and away from the locking groove 101. The first guide wall 1021 guides the locking block 102 to engage with the locking groove 101, and the second guide wall 1022 guides the locking block 102 to disengage from the locking groove 101. By providing the first guide wall 1021 and the second guide wall 1022 facing opposite directions on the outside of the locking block 102, the engagement and disengagement between the locking block 102 and the locking groove 101 can be made smoother, thereby improving the convenience of assembling and disassembling the milk bowl body 1. Optionally, the first guide wall 1021 and the second guide wall 1022 can be set as arc-shaped walls or inclined walls. This utility model does not make specific limitations.
[0044] Furthermore, such as Figure 6 and Figure 9 As shown, the outer side of the slot 101 is provided with a third guide wall 1014 corresponding to the first guide wall 1021 and a fourth guide wall 1015 corresponding to the second guide wall 1022. The third guide wall 1014 is away from the slot 101, and the fourth guide wall 1015 faces the slot 101. In practical applications, when assembling the milk bowl body 1, the third guide wall 1014 guides the locking block 102 to engage with the slot 101; when disassembling the milk bowl body 1... The fourth guide wall 1015 guides the locking block 102 to disengage from the slot 101. By providing the third guide wall 1014 and the fourth guide wall 1015 on the outside of the slot 101, it is beneficial to improve the locking and disassembly efficiency of the first locking part 112 and the second locking part 122, thereby improving the disassembly and assembly efficiency of the milk bowl body 1. Optionally, the third guide wall 1014 and the fourth guide wall 1015 can be set as arc-shaped walls or inclined walls, and this utility model does not make specific limitations.
[0045] To further improve the connection stability between the front shell 11 and the rear shell 12 of the milk bowl and prevent milk leakage, such as Figure 4 and Figure 9As shown, the main body 1 of the milk bowl also includes a sealing ring 16, which is disposed on one side of the first snap-fit portion 112 or the second snap-fit portion 122. The sealing ring 16 closes the assembly gap between the front shell 11 and the rear shell 12 of the milk bowl, thereby sealing the front shell 11 and the rear shell 12 of the milk bowl. Optionally, the sealing ring 16 can be disposed in the front shell 11 of the milk bowl and abut against the second connecting wall 121 in the rear shell 12 of the milk bowl. Alternatively, the sealing ring 16 can be disposed in the rear shell 12 of the milk bowl and abut against the first connecting wall 111 in the front shell 11 of the milk bowl. This utility model does not impose specific limitations.
[0046] To facilitate manual disassembly of the milk bowl body 1 by the user, such as Figure 1 and Figure 2 As shown, the operating part 15 includes a first operating part 15 disposed outside the front shell 11 of the milk bowl and a second operating part 15 disposed outside the rear shell 12 of the milk bowl. The first operating part 15 and the second operating part 15 provide the user's hands with a fulcrum for applying force, thereby improving the convenience of manually disassembling the milk bowl body 1 and making it easier for the user to disassemble and assemble the milk bowl body 1. Furthermore, the first operating part 15 includes at least one of a handle groove 1501 and a gripping protrusion 1502, and the second operating part 15 includes at least one of a handle groove 1501 and a gripping protrusion 1502. The first operating part 15 and the second operating part 15 have simple structures and are easy to implement.
[0047] Optionally, the outer wall of the front shell 11 of the milk bowl is provided with a plurality of handle grooves 1501, each handle groove 1501 being evenly distributed along the circumference of the front shell 11. The bottom of the front shell 11 of the milk bowl is also provided with a gripping protrusion 1502, and the bottom of the rear shell 12 of the milk bowl is also provided with a gripping protrusion 1502. The gripping protrusions 1502 of the front shell 11 and the gripping protrusions 1502 of the rear shell 12 of the milk bowl are staggered to facilitate manual disassembly of the front shell 11 and the rear shell 12 of the milk bowl by the user. 2; Alternatively, at least one handle groove 1501 may be provided on the outer wall of the rear shell 12 of the milk bowl; it should be noted that the handle groove 1501 can accommodate at least one finger. If the outer wall of the milk bowl body 1 is provided with two or more handle grooves 1501, the handle grooves 1501 at different positions correspond to different fingers of the user, so as to facilitate the user to apply force. The number, shape and layout design of the handle grooves 1501 can be flexibly selected, and this utility model does not make specific limitations.
[0048] On the other hand, in order to further improve the ease of assembly of the wearable breast pump device, such as Figure 1 , 3 8 and Figure 15 , 16As shown, the wearable breast pump device also includes a breast pumping unit 2 slidably connected to the breast bowl body 1. The breast pumping unit 2 is used to provide a negative pressure source. The breast bowl body 1 has an installation cavity 171 for installing the breast pumping unit and a partition wall 172 located between the installation cavity 171 and the milk storage cavity 13. The breast pumping unit 2 is detachably slidably installed into the installation cavity 171. The partition wall 172 surrounds and forms the installation cavity 171, and isolates the installation cavity 171 and the milk storage cavity 13. In practical applications, the user can directly insert the breast pumping unit 2 into the installation cavity 171, and can directly pull the breast pumping unit 2 out of the installation cavity 171 to disassemble the breast pumping unit 2. Compared to existing breast pumps where the negative pressure device is connected via screws and other accessories, the breast pump unit 2 in this embodiment can slide relative to the mounting cavity 171 to achieve assembly of the breast pump unit 2. This greatly simplifies the assembly structure of the breast pump unit 2, eliminating the need for screw-to-hole assembly, reducing the assembly difficulty of the breast pump unit 2, and making it easier for users to assemble and disassemble the wearable breast pump device. In addition, the milk bowl body 1 is also provided with a partition wall 172 between the mounting cavity 171 and the milk storage cavity 13. The partition wall 172 isolates the mounting cavity 171 from the milk storage cavity 13, ensuring the sealing and cleanliness of the milk storage cavity 13, and preventing breast milk from seeping into the breast pump unit 2 and causing easy damage to the breast pump unit 2.
[0049] Optional, such as Figure 1 , 3 As shown in Figure 8, the mounting cavity 171 can be disposed in the front shell 11 of the milk bowl, and the partition wall 172 is correspondingly disposed in the front shell 11 of the milk bowl; alternatively, as shown in Figure 8... Figure 15 and Figure 16 The mounting cavity 171 shown can be set in the rear shell 12 of the milk bowl, and the partition wall 172 is correspondingly set in the rear shell 12 of the milk bowl. This utility model does not make specific limitations. In addition, the milk pumping host 2 can refer to the design of a common breast pump negative pressure pump, and the milk pumping function of the wearable breast pumping device can be realized by the milk pumping principle in the prior art. This utility model does not make specific limitations.
[0050] Furthermore, a limiting structure is provided between the breast pump 2 and the mounting cavity 171. This limiting structure prevents the breast pump 2 from detaching from the mounting cavity 171, thus preventing it from falling out of the cavity due to gravity when facing the ground. This helps protect the breast pump 2 and ensures the normal operation of the breast pump device. Optionally, the limiting structure can be a snap-fit structure; this invention does not specify a particular one. The breast pump 2 can be pulled out of the mounting cavity 171 by the user applying a certain pulling force. Further, the breast pump 2 is provided with a drive unit on its exterior for user operation. This drive unit provides a fulcrum for the user to apply force, thereby facilitating the user's disassembly of the breast pump 2. Optionally, the drive unit can be a handle groove, a gripper protrusion, or other structures; this invention does not specify a particular one.
[0051] Example 2:
[0052] like Figure 3 As shown in —11, Figure 6 Arrow S1 indicates the snap-fit direction of the milk bowl body 1, and arrow S2 indicates the disassembly direction of the milk bowl body 1. Based on the above embodiment one, this embodiment two provides a specific implementation of one of the first snap-fit parts 112 and the second snap-fit part 122. Specifically, the slot 101 includes a snap-fit opening 1011 and a receiving groove 1012 communicating with the snap-fit opening 1011. The snap-fit opening 1011 is axially disposed on one side of the receiving groove 1012, and the snap-fit block 102 extends radially toward the milk storage chamber 13. The receiving groove 1012 is used to accommodate the snap-fit block 102. It should be noted that the axial direction is the axial direction of the milk bowl body 1, and the radial direction is the radial direction of the milk bowl body 1.
[0053] In this embodiment, the first latching part 112 is configured as a latching groove 101, the second latching part 122 is configured as a corresponding latching block 102, and the first connecting wall 111 is connected to the inner side of the second connecting wall 121. The first guide wall 1021 is located on the front side of the latching block 102, and the second guide wall 1022 is located on the rear side of the latching block 102. The first guide wall 1021 and the second guide wall 1022 are respectively arranged obliquely along the radial direction of the milk bowl body 1. In practical applications, when assembling the milk bowl body 1, the latching block 102 is arranged along the radial direction of the milk bowl body 1. The locking block 102 moves towards the locking slot 101 in the direction of the locking action and is guided by the first guide wall 1021 to engage with the receiving groove 1012 through the locking slot 1011, thereby connecting the front shell 11 and the rear shell 12 of the milk bowl; when the milk bowl body 1 is disassembled, the locking block 102 moves away from the locking slot 101 in the direction of disassembly and is guided by the second guide wall 1022 to disengage from the receiving groove 1012 through the locking slot 1011, thereby separating the front shell 11 and the rear shell 12 of the milk bowl.
[0054] Optional, such as Figure 7 As shown, the card block 102 has arc-shaped walls at both ends. The arc-shaped walls form the first guide wall 1021 and the second guide wall 1022 on the front and rear sides of the card block 102. This simplifies the structure of the card block 102, thereby reducing the processing difficulty and production cost of the milk bowl body 1. Furthermore, the first guide wall 1021 and the second guide wall 1022 are connected to form the arc-shaped walls, which helps to improve the smoothness of insertion and removal between the card block 102 and the card slot 101, and facilitates the assembly and disassembly of the milk bowl front shell 11 and the milk bowl rear shell 12.
[0055] In other alternative embodiments, such as Figure 7 As shown, the length of the locking block 102 gradually decreases radially, and the maximum length L1 of the locking block 102 is greater than the width L3 of the latch 1011, while the minimum length L2 of the locking block 102 is less than the width L3 of the latch 1011. Specifically, the side of the locking block 102 connected to the milk bowl body 1 is designated as the top 1023, and the side of the locking block 102 away from the milk bowl body 1 is designated as the bottom 1024. The length of the locking block 102 gradually decreases radially from the top 1023 towards the bottom 1024, and the first guide wall 10 is formed on both the front and rear sides of the locking block 102. 21 and second guide wall 1022, the bayonet 1011 and the receiving groove 1012 are arranged axially, and the bayonet 1011 and the receiving groove 1012 are arranged sequentially along the snapping direction of the snap block 102; when the snap block 102 is inserted into or detached from the receiving groove 1012 through the bayonet 1011, the snap block 102 is guided to move axially relative to the bayonet 1011 by the first guide wall 1021 or the second guide wall 1022, so that the snap block 102 can enter or detach from the receiving groove 1012 through the bayonet 1011, thereby realizing the assembly and disassembly of the milk bowl front shell 11 and the milk bowl rear shell 12.
[0056] In this embodiment, as Figure 6 and Figure 11 As shown, the latch 1011 has limiting portions 1013 on both sides, and the two limiting portions 1013 are arranged opposite to each other. The two limiting portions 1013 restrict the latch 102 from leaving the receiving groove 1012 through the latch 1011. Specifically, the limiting portion 1013 is provided between the latch 1011 and the receiving groove 1012, that is, the width L3 of the latch 1011 is narrowed by the two limiting portions 1013, so that the width L3 of the latch 1011 is less than the maximum width L4 of the receiving groove 1012. This is to facilitate the restriction by the two limiting portions 1013 so that the latch 102 can leave the receiving groove 1012 without being subjected to appropriate external force, thus ensuring the normal progress of the breast pumping process.
[0057] Furthermore, such as Figure 6 As shown, both of the limiting portions 1013 are provided with arc-shaped outer walls, which form the third guide wall 1014 and the fourth guide wall 1015.
[0058] In practical applications, when assembling the milk bowl body 1, the milk bowl rear shell 12 drives the locking block 102 to move relative to the latch 1011 toward the receiving groove 1012, and the third guide wall 1014 generates a reaction force on the first guide wall 1021. At this time, the milk bowl rear shell 12 is guided by the first guide wall 1021 to expand and deform outward to a certain extent, so that the locking block 102 moves upward relative to the latch 1011, allowing the locking block 102 to pass through the latch 1011. Simultaneously, the third guide wall 1014 guides the locking block 102 into the receiving groove 1012. Subsequently, The rear shell 12 of the milk bowl recovers its original shape due to its own elasticity and retracts inward, causing the locking block 102 to move downward relative to the locking slot 1011 and be placed in the receiving groove 1012. At this time, the maximum length L1 of the locking block 102 is opposite to the limiting portions 1013 on both sides of the locking slot 1011, thereby preventing the locking block 102 from detaching from the receiving groove 1012, so as to avoid the locking block 102 from detaching from the locking slot 101 due to vibration during use of the breast pump, and ensuring the normal operation of the breast pumping process; when the milk bowl body 1 is disassembled, the locking block 102 moves away from the receiving groove 1012 relative to the locking slot 1011, and the fourth guide The second guide wall 1022 is subjected to a reaction force by the first guide wall 1015. At this time, the second guide wall 1022 guides the rear shell 12 of the milk bowl to expand and deform outwards to a certain extent, causing the locking block 102 to move upwards relative to the latch 1011, allowing it to pass through the latch 1011. Simultaneously, the fourth guide wall 1015 guides the locking block 102 to disengage from the receiving groove 1012. Subsequently, the rear shell 12 of the milk bowl elastically returns to its original shape and contracts inwards, causing the locking block 102 to automatically reset. It should be noted that when the user manually disassembles the front shell 11 and the rear shell 12 of the milk bowl, the… The user applies appropriate external force to the front shell 11 and the rear shell 12 of the milk bowl, causing them to move relative to each other in the snap-fit and disassembly directions. This allows for detachable connection via the first snap-fit part 112 and the second snap-fit part 122. The user does not need to perform any other operations, making the operation simple and easy to assemble and disassemble the milk bowl body 1. Furthermore, the vibration force generated on the locking block 102 by the milk pumping device during milk pumping is less than the force required for the locking block 102 to disengage from the locking groove 101. It should be noted that the milk bowl body 1 can be made of materials such as PP, giving the front shell 11 and the rear shell 12 a certain degree of elasticity to achieve the snap-fit between them.

The outer wall of the annular snap-fit block 102 is configured as an arc-shaped outer wall to form a first guide wall 1021 located outside the snap-fit block 102 and a second guide wall 1022 located inside the snap-fit block 102.
[0062] Furthermore, such as Figure 14 As shown, the front shell 11 of the milk bowl is provided with a first fixing wall 103 and a second fixing wall 104 located on the front and rear sides of the slot 101. Optionally, the front shell 11 of the milk bowl is provided with a positioning block 105 located outside the slot 101, and the first fixing wall 103 is formed by the side of the positioning block 105 facing the slot 101. The outer wall of the positioning block 105 is set as an arc-shaped outer wall to form a third guide wall 1014 located outside the positioning block 105 and away from the slot 101, and a fourth guide wall 1014 located inside the positioning block 105 and facing the slot 101. 015. On the other hand, a sealing ring 16 is provided on the outside of the first connecting wall 111 of the front shell 11 of the milk bowl. The sealing ring 16 is located inside the slot 101 and is opposite to the positioning block 105. The second fixing wall 104 is formed on the side of the sealing ring 16 facing the slot 101. When the front shell 11 and the rear shell 12 of the milk bowl are connected, the locking block 102 is engaged in the slot 101 and clamped by the extension block and the sealing ring 16, so that the milk bowl assembly is assembled and the sealing performance of the milk bowl assembly is improved to prevent milk leakage.
[0063] It should be noted that in this embodiment, the guiding process of the first guide wall 1021 and the third guide wall 1014, and the second guide wall 1022 and the fourth guide wall 1015 is similar to that in Embodiment 2 above, and will not be repeated here.
