Description

Technical Field

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

[0002] A breast pump is a tool used to express breast milk accumulated in the mammary glands. It uses an internal vacuum pump to change the internal air pressure, i.e., to perform a cyclical suction and release operation, simulating the action of a baby sucking breast milk. To meet the needs of users for discreet breast pumping in public places, wearable breast pumps that can be inserted into a bra have emerged. Most existing wearable breast pumps are oval or egg-shaped, and the whole machine is still relatively thick and heavy, with a large size. In addition, some existing wearable breast pumps use two shells connected by snap-fit ​​assembly, which can easily lead to milk leakage during pumping. At the same time, the milk bowl is not easy to open after assembly, requiring a lot of effort to disassemble, which is inconvenient for users to frequently clean and assemble the milk bowl.

[0003] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0004] This invention addresses the problems mentioned above regarding existing wearable breast pumps, such as easy milk leakage during pumping, difficulty in opening the assembled milk bowl, and inconvenience for frequent cleaning and assembly. It proposes a milk bowl assembly for a breast pump and a wearable breast pumping device.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A breast pump bowl assembly includes a bowl body, which comprises a front shell and a rear shell, with a milk storage chamber between the front and rear shells. The front and rear shells are provided with a rotating assembly structure, which includes a first screw-on portion on the front shell and a second screw-on portion on the rear shell corresponding to the first screw-on portion. The front and rear shells are detachably connected by rotating the first and second screw-on portions.

[0007] As described above, in a breast pump bowl assembly, the first screw-on portion includes a first inclined surface disposed on the front shell, and the second screw-on portion includes a second inclined surface disposed on the rear shell and adapted to the first inclined surface. The first and second screw-on portions are connected by the relative rotation and abutment of the first and second inclined surfaces.

[0008] As described above, a breast pump bowl assembly includes a first screw-on portion comprising a first mounting wall disposed on the front shell and a first protrusion disposed on the first mounting wall, with a first inclined surface disposed on the first protrusion; and a second screw-on portion comprising a second mounting wall disposed on the rear shell and a second protrusion disposed on the second mounting wall, with a second inclined surface disposed on the second protrusion.

[0009] As described above, a breast pump bowl assembly includes a first screw-on portion comprising a first mounting wall on the front shell and a first snap-on portion on the first mounting wall; and a second screw-on portion comprising a second mounting wall on the rear shell and a second snap-on portion on the second mounting wall. One of the first snap-on portions and the second snap-on portion is configured as a snap block, and the other snap-on portion is configured as a corresponding connecting groove.

[0010] As described above, a breast pump bowl assembly includes a connecting groove with a locking block inlet and a locking block fixing position. The locking block moves from the locking block inlet along the connecting groove to the locking block fixing position, thereby connecting the first locking part and the second locking part. The connecting groove includes a first groove segment and a second groove segment that communicate with each other. The locking block inlet is located at the beginning of the first groove segment, and the locking block fixing position is located at the end of the second groove segment.

[0011] In the breast pump bowl assembly described above, at least one of the relative rotational surfaces between the first screw-in portion and the second screw-in portion is designated as a limiting surface, which serves to restrict the axial separation of the first screw-in portion and the second screw-in portion.

[0012] As described above, a breast pump bowl assembly has at least one handle on the outer wall of the front shell and / or the outer wall of the rear shell.

[0013] As described above, a breast pump bowl assembly includes a front shell with a milk-suction section located on one side of the first screw-on portion and a connecting portion located on one side of the milk-suction section for mounting a bra. The rear shell has a first negative pressure section opposite to the milk-suction section. The milk-suction section extends at least partially into the inner side of the first negative pressure section. The bowl assembly also includes a flexible diaphragm located outside the milk-suction section and capable of elastic deformation. By rotating the first screw-on portion and the second screw-on portion relative to each other, the milk-suction section and the first negative pressure section rotate relative to each other, thereby clamping the flexible diaphragm between the milk-suction section and the first negative pressure section.

[0014] As described above, a breast pump bowl assembly includes a first annular extension extending radially on the outer side of the milk suction part, a second annular extension extending axially at one end of the first negative pressure part, a third annular extension that fits into the first annular extension on the flexible diaphragm, and the third annular extension being clamped by the first and second annular extensions; the outer edge of the third annular extension is provided with a flange.

[0015] As described above, in a breast pump bowl assembly, the front shell is provided with a second negative pressure part located on one side of the first screw joint, the second negative pressure part being used to install a breast shield, the breast shield being provided with an integrally formed flexible diaphragm.

[0016] This invention also provides a wearable breast pumping device, including the milk bowl assembly described above.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model provides a breast pump bowl assembly, including a bowl body, which includes a front shell and a rear shell. The front and rear shells are provided with a rotating assembly structure, which includes a first screw-on portion on the front shell and a second screw-on portion on the rear shell. The second screw-on portion corresponds to the first screw-on portion, and the front and rear shells are detachably rotatably connected via the first and second screw-on portions. The front and rear shells rotate relative to each other under force, causing the first and second screw-on portions to rotate relative to each other, thus allowing them to engage and connect. Rotating the first and second screw-on portions in opposite directions allows the front and rear shells to be disassembled for easy cleaning of the inside of the bowl. Compared to the snap-on assembly structure of the milk bowl in existing wearable breast pumps, the rotating assembly structure in this invention reduces the difficulty of disassembling and assembling the front and rear shells of the milk bowl, making it easier for users to disassemble and assemble the main body of the milk bowl. Moreover, when the front and rear shells are connected by the first and second screw joints, the rotation between the first and second screw joints is accompanied by the relative axial displacement between the first and second screw joints, which generates an axial clamping force between the first and second screw joints, thereby enhancing the connection and sealing between the front and rear shells and preventing milk leakage from the main body of the milk bowl.

[0039] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0040] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0041] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. 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.

[0042] Example 1:

[0043] like Figure 1As shown in Figure 7, this utility model provides a wearable breast pump device. The wearable breast pump device includes a milk bowl assembly, which includes a milk bowl body 1. The milk bowl body 1 includes a front shell 11 and a rear shell 12. A milk storage chamber 13 is provided between the front shell 11 and the rear shell 12. The milk bowl body 1 is provided with a milk pouring port 14 communicating with the milk storage chamber 13. The milk storage chamber 13 can accommodate breast milk and can directly pour out breast milk through the milk pouring port 14. The front shell 11 and the rear shell 12 are provided with a rotating assembly structure 15. The rotating assembly structure 15 includes a first screw-on part 151 provided on the front shell 11 and a second screw-on part 152 provided on the rear shell 12. The second screw-on part 152 corresponds to the first screw-on part 151. The front shell 11 and the rear shell 12 are detachably rotatably connected through the first screw-on part 151 and the second screw-on part 152.

[0044] In this embodiment, the front shell 11 and the rear shell 12 rotate relative to each other under force, which in turn causes the first screw-on part 151 and the second screw-on part 152 to rotate relative to each other. This allows the first screw-on part 151 and the second screw-on part 152 to engage and connect with each other. Rotating the first screw-on part 151 and the second screw-on part 152 in opposite directions allows the front shell 11 and the rear shell 12 to be disassembled, facilitating cleaning of the inside of the milk bowl by the user. Compared to the snap-on assembly structure of the milk bowl in existing wearable breast pumps, the rotating assembly structure 15 in this embodiment reduces the height of the front shell 11 and the rear shell 12. The ease of disassembling and assembling the rear shell 12 makes it easier for users to disassemble and assemble the main body of the milk bowl 1. Moreover, when the front shell 11 and the rear shell 12 are connected by the first screw joint 151 and the second screw joint 152, the rotation between the first screw joint 151 and the second screw joint 152 is accompanied by the relative axial displacement of the first screw joint 151 and the second screw joint 152, which generates an axial clamping force between the first screw joint 151 and the second screw joint 152, thereby enhancing the connection sealing between the front shell 11 and the rear shell 12 and preventing milk leakage from the main body of the milk bowl 1.

[0045] In addition, preferably, in order to improve the user's wearing comfort, the outer wall of the back shell 12 is set as an arc surface or a spherical surface, and the longitudinal section of the milk bowl body 1 is approximately circular. While ensuring the milk storage capacity of the milk storage chamber 13, the volume of the wearable breast pump can be reduced, further improving the user experience.

[0046] Preferred, such as Figure 7 As shown, the longitudinal section 150 of the relative rotation surface between the first screw joint 151 and the second screw joint 152 is set as a circle, so that the first screw joint 151 and the second screw joint 152 can be automatically aligned, which is beneficial to ensure the rotational assembly between the first screw joint 151 and the second screw joint 152.

[0047] Furthermore, such as Figure 5As shown, a first limiting structure is provided between the first screw-in portion 151 and the second screw-in portion 152. The first limiting structure includes a limiting surface 16 located between the first screw-in portion 151 and the second screw-in portion 152. At least one of the relative rotational surfaces between the first screw-in portion 151 and the second screw-in portion 152 is designated as the limiting surface 16. The limiting surface 16 has the function of restricting the axial separation of the first screw-in portion 151 and the second screw-in portion 152. After the first screw-in portion 151 and the second screw-in portion 152 rotate relative to each other and are connected, the first screw-in portion 151 and the second screw-in portion 152 abut against each other. The limiting surface 16 is located between the first screw-in portion 151 and the second screw-in portion 152. In the contact surface between part 151 and the second screw-on part 152, the limiting surface 16 generates an axial component force to restrict the axial separation of the front shell 11 and the rear shell 12, thereby ensuring the normal use of the wearable breast pump. In this embodiment, the first limiting structure is formed by the structure of the first screw-on part 151 and the second screw-on part 152, which can further improve the connection tightness of the front shell 11 and the rear shell 12. There is no need to set an additional limiting part in the milk bowl, which helps to simplify the structure of the milk bowl body 1, reduce the processing difficulty of the milk bowl body 1, and reduce the weight of the wearable breast pump, thereby reducing the burden on users when using the wearable breast pump outside and optimizing the user experience.

[0048] like Figure 5 As shown, in an optional embodiment of the rotary assembly structure 15, the first screw-on portion 151 includes a first inclined surface 1511 disposed on the front shell 11, and the second screw-on portion 152 includes a second inclined surface 1521 disposed on the rear shell 12 and adapted to the first inclined surface 1511. The first inclined surface 1511 and the second inclined surface 1521 rotate relative to each other and abut against each other, thereby connecting the first screw-on portion 151 and the second screw-on portion 152. At least one of the inclined surfaces 1511 and 1521 serves as the limiting surface 16 to restrict the axial separation of the front shell 11 and the rear shell 12. In this embodiment, a helical motion is generated between the first screw-on portion 151 and the second screw-on portion 152, which is converted into relative axial displacement, so that the first inclined surface 1511 and the second inclined surface 1521 abut tightly, thereby achieving a tight connection between the front shell 11 and the rear shell 12.

[0049] Optionally, the first inclined surface 1511 and the second inclined surface 1521 can be respectively provided in the external thread and the internal thread that can mesh with each other. For example, the first inclined surface 1511 is provided in the external thread or the internal thread, and the second inclined surface 1521 is provided in correspondence with the first inclined surface 1511. This embodiment does not make specific limitations.

[0050] Another option, such as Figure 5As shown, the first screw-on portion 151 includes a first mounting wall 1512 disposed on the front shell 11 and a first protrusion 1513 disposed on the first mounting wall 1512, with a first inclined surface 1511 disposed on the first protrusion 1513. The second screw-on portion 152 includes a second mounting wall 1522 disposed on the rear shell 12 and a second protrusion 1523 disposed on the second mounting wall 1522, with a second inclined surface 1521 disposed on the second protrusion 1523. The first mounting wall 1512 and the second mounting wall 1522 are configured as columnar walls that can cooperate with each other. The first protrusion 1513 and the second protrusion 1523 are respectively disposed in the first mounting wall 1512 and the second mounting wall 1522. The first mounting wall 1512 can be connected to the outside of the second mounting wall 1522, or the second mounting wall 1522 can be connected to the outside of the first mounting wall 1512. This embodiment does not make specific limitations. By setting a first protrusion 1513 and a second protrusion 1523 that are compatible with each other, and setting a first inclined surface 1511 and a second inclined surface 1521 that are compatible with each other in the first protrusion 1513 and the second protrusion 1523, it is beneficial to simplify the rotary assembly structure 15, reduce the processing difficulty of the rotary assembly structure 15, and reduce the cleaning dead angle between the first screw joint 151 and the second screw joint 152, thus ensuring the hygiene of breast milk and the health of the baby.

[0051] Optionally, the first protrusion 1513 is obliquely disposed on the first mounting wall 1512 and extends circumferentially to form the first inclined surface 1511 on the outer wall of the first protrusion 1513, and the second protrusion 1523 is disposed on the second mounting wall 1522 and extends circumferentially to form the second inclined surface 1521 on the outer wall of the second protrusion 1523. When the first screw joint 151 and the second screw joint 152 are subjected to force and generate relative spiral movement, the first inclined surface 1511 and the second inclined surface 1521 continuously approach and abut against each other along the axial direction to realize the rotational assembly of the front shell 11 and the rear shell 12.

[0052] Alternatively, the first assembly wall 1512 may be provided with a plurality of first protrusions 1513 evenly distributed circumferentially, and the second assembly wall 1522 may be provided with a plurality of second protrusions 1523. Each first protrusion 1513 is provided with a first inclined surface 1511, and each second protrusion 1523 is provided with a second inclined surface 1521, which is beneficial to improving the connection stability and sealing of the front shell 11 and the rear shell 12.

[0053] In some alternative embodiments, to further improve the sealing connection between the front shell 11 and the rear shell 12, such as Figure 3 and Figure 13As shown, the milk bowl body 1 is provided with a sealing ring 101 located on one side of the rotating assembly structure 15; optionally, as... Figure 13 As shown, the sealing ring 101 is disposed inside the front shell 11 and abuts against the end face of the second assembly wall 1522 in the rear shell 12. The sealing ring 101 seals the assembly gap between the first screw-on part 151 and the second screw-on part 152 to prevent milk leakage. At the same time, when the first screw-on part 151 and the second screw-on part 152 are rotated and assembled, the first screw-on part 151 and the second screw-on part 152 generate relative axial displacement, which allows the sealing ring 101 to be pressed tightly, improving the connection tightness of the sealing ring 101, thereby improving the sealing performance of the milk bowl body 1.

[0054] In other alternative implementations, such as Figure 13 As shown, the sealing ring 101 is disposed inside the rear shell 12 and abuts against the end face of the first mounting wall 1512 in the front shell 11. The specific arrangement of the sealing ring 101 is not limited in this utility model. In addition, the sealing ring 101 can be inserted into the milk bowl body 1 through a corresponding annular groove, or it can be fixedly connected to the milk bowl body 1 by means of adhesive bonding, etc. This embodiment does not make specific limitations.

[0055] In other alternative embodiments, to facilitate user disassembly and assembly of the milk bowl body 1, such as... Figure 2 As shown, the outer wall of the front shell 11 and / or the outer wall of the rear shell 12 are provided with at least one handle position 17. The handle position 17 is formed by the indentation of the outer wall of the milk bowl body 1 toward the milk storage cavity 13. The outer wall of the milk bowl body 1 includes the outer wall of the front shell 11 and the outer wall of the rear shell 12. Each handle position 17 can accommodate at least one finger. By providing handle positions 17 on the outer wall of the milk bowl body 1, a force fulcrum can be provided for the user, making it easier for the user to disassemble and assemble the front shell 11 and the rear shell 12. Optionally, a plurality of handle positions 17 are provided in the annular wall on the outer side of the front shell 11, and / or at least two handle positions 17 are provided in the arc-shaped wall on the outer side of the rear shell 12. The handle positions 17 in different positions correspond to different fingers of the user, so as to facilitate the user to apply force. It should be noted that the number, shape and layout design of the handle positions 17 can be flexibly selected, and this utility model does not impose specific limitations.

[0056] In other alternative embodiments, to further optimize the component assembly of the wearable breast pump, such as... Figure 14As shown, the wearable breast pump device also includes a breast pumping unit 2 for providing a negative pressure source. The milk bowl body 1 has an outwardly open mounting cavity 18, and the breast pumping unit 2 is detachably slidably installed into the mounting cavity 18. In this embodiment, the mounting cavity 18 is a sliding cavity for sliding assembly of the breast pumping unit 2. The mounting cavity 18 is adapted to the breast pumping unit 2, and the user can directly insert the breast pumping unit 2 into the mounting cavity 18 and directly pull the breast pumping unit 2 out of the mounting cavity 18 to disassemble the breast pumping unit 2. Compared with the negative pressure device in existing breast pumps, which is connected by screws and other accessories, the breast pumping unit 2 in this embodiment can slide relative to the mounting cavity 18 to provide a negative pressure source. The assembly of the breast pump 2 is greatly simplified, eliminating the need for screw-to-hole assembly and reducing the assembly difficulty. This makes it easier for users to assemble and disassemble the wearable breast pump. Furthermore, the milk bowl body 1 includes a partition wall 102 between the mounting cavity 18 and the milk storage cavity 13. This partition wall 102 isolates the mounting cavity 18 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 2 and causing damage. Optionally, the mounting cavity 18 can be located in the front shell 11 or the rear shell 12; this embodiment does not impose a specific limitation.

[0057] Furthermore, to prevent the breast pump 2 from sliding out of the mounting cavity 18 on its own, such as... Figure 14 As shown, the wearable breast pump device further includes a second limiting structure 3, which restricts the breast pump 2 from detaching from the mounting cavity 18. Optionally, the second limiting structure 3 includes a third locking part 31 located outside the breast pump 2 and a fourth locking part 32 located inside the mounting cavity 18. One of the third locking parts 31 and the fourth locking part 32 is configured as a third protrusion, and the other locking part is configured as a corresponding slot. When the breast pump 2 is slidably installed into the mounting cavity 18, it can be detached by the corresponding locking parts 31 and 32. The locking mechanism enhances the connection stability of the breast pump 2, preventing it from easily sliding out of the mounting cavity 18 when facing the ground due to gravity. This ensures the normal use of the wearable breast pump and protects the breast pump 2. When the user disassembles the breast pump 2, the breast pump 2 can overcome the force in the second limiting structure 3 by applying appropriate external force and can be disassembled. Optionally, the outer side of the third protrusion is provided with an arc-shaped chamfer to facilitate the connection or separation of the third protrusion from the slot, making the breast pump 2 easier to disassemble and assemble.

[0058] Optionally, at least one handle groove 21 may be provided on the outside of the breast pump host 2 to facilitate manual disassembly of the breast pump host 2. The handle groove 21 may be similar to the handle position 17, which will not be described in detail in this embodiment.

[0059] like Figure 3 As shown in Figure 9, one possible embodiment of the mounting cavity 18 is that the mounting cavity 18 is disposed in the rear shell 12, the partition wall 102 is disposed in the rear shell 12 and extends toward the front shell 11, and the partition wall 102 extends into the milk storage cavity 13, so that the breast pumping unit 2 can be installed inside the rear shell 12, thereby making the internal structure of the wearable breast pumping device more compact, which is beneficial to reducing the volume and thickness of the wearable breast pumping device, thereby improving the user's wearing comfort; during the rotational assembly of the front shell 11 and the rear shell 12, the second mating shell can be driven by the rear shell 12 to rotate relative to the front shell 11 in the milk storage cavity 13, so as to ensure the connection of the first screw joint 151 and the second screw joint 152; preferably, the outer wall of the breast pumping unit 2 and the outer wall of the rear shell 12 are in the same arc surface, which is beneficial to improving the user's wearing comfort; in this solution, the milk discharge port 14 can be disposed on the top of the front shell 11.

[0060] like Figure 17 As shown in Figure 19, in another optional embodiment of the mounting cavity 18, the mounting cavity 18 is disposed on the front shell 11, and the partition wall 102 is disposed on the front shell 11 and extends toward the rear shell 12, so that the breast pumping unit 2 can be installed inside the front shell 11, thereby making the internal structure of the wearable breast pumping device more compact, which is beneficial to reducing the volume and thickness of the wearable breast pumping device, thereby improving the user's wearing comfort; during the rotational assembly of the front shell 11 and the rear shell 12, the partition wall 102 can be driven by the front shell 11 to rotate relative to the rear shell 12 in the milk storage cavity 13, so as to ensure the connection of the first screw joint 151 and the second screw joint 152; in this solution, the milk pouring port 14 can be disposed on the top of the rear shell 12.

[0061] Example 2:

[0062] like Figure 8As shown in Figure 12, the difference between this second embodiment and the first embodiment described above is that the first screw-on portion 151 includes a first mounting wall 1512 disposed on the front shell 11 and a first snap-fit ​​portion 1514 disposed on the first mounting wall 1512; the second screw-on portion 152 includes a second mounting wall 1522 disposed on the rear shell 12 and a second snap-fit ​​portion 1524 disposed on the second mounting wall 1522; one snap-fit ​​portion of the first snap-fit ​​portion 1514 and the second snap-fit ​​portion 1524 is configured as a snap-fit ​​block, and the other snap-fit ​​portion is configured as a corresponding connecting groove; in this embodiment, the first mounting wall 1512 and the second mounting wall 1522 are configured to cooperate with each other. The columnar wall, the first assembly wall 1512 can be connected to the outside of the second assembly wall 1522, or the second assembly wall 1522 can be connected to the outside of the first assembly wall 1512. This embodiment does not make a specific limitation. By setting the rotary assembly structure 15 as a snap-fit ​​rotary assembly structure 15, the assembly structure between the front shell 11 and the rear shell 12 can be simplified, greatly reducing the difficulty of disassembling and assembling the front shell 11 and the rear shell 12. It can also reduce the cleaning dead corners in the first screw joint 151 and the second screw joint 152, thereby reducing the cleaning difficulty of the milk bowl body 1 and ensuring the hygiene of the milk and the health of the baby.

[0063] Specifically, such as Figure 10 As shown in Figure 12, the connecting groove is provided with a locking block inlet 15241 and a locking block fixing position 15242. The locking block inlet 15241 is located at the first end of the connecting groove, and the locking block fixing position 15242 is located at the end of the connecting groove. The locking block moves from the locking block inlet 15241 along the connecting groove to the locking block fixing position 15242, so that the first locking part 1514 and the second locking part 1524 are connected. When the locking block is in the locking block fixing position 15242, at least one side of the front and rear sides of the locking block abuts against the inner wall of the connecting groove to form a limiting surface 16 for limiting the axial separation of the front shell 11 and the rear shell 12, thereby improving the connection stability between the front shell 11 and the rear shell 12 and effectively preventing milk leakage. It should be noted that the front and rear sides of the locking block are set along the axial direction of the milk bowl body 1.

[0064] In this embodiment, the movement of the card block along the connecting groove can be a helical motion, or the movement of the card block along the connecting groove can be a combination of axial linear movement and rotational movement; this embodiment does not specifically limit this. Optionally, such as... Figure 10As shown, the connecting groove can be inclinedly disposed in the first assembly wall 1512 or the second assembly wall 1522. The inclination trend of the connecting groove is consistent with the spiral trend between the first snap-fit ​​part 1514 and the second snap-fit ​​part 1524, that is, the connecting groove can be configured as a spiral groove, so that the snap-fit ​​block can be detachably screwed into the connecting groove. The connecting groove is provided with a guide wall 15240 opposite to the snap-fit ​​block. The guide wall 15240 guides the snap-fit ​​block from the snap-fit ​​block inlet 15241 along the connecting groove to the snap-fit ​​block fixing position 15242, so as to improve the assembly smoothness of the first snap-fit ​​part 151 and the second snap-fit ​​part 152. When the snap-fit ​​block is in the snap-fit ​​block fixing position 15242, the guide wall 15240 can also restrict the snap-fit ​​block from disengaging from the connecting groove in a natural state. The natural state refers to the state in which the snap-fit ​​block is not subjected to disassembly external force.

[0065] In other embodiments of the connecting slot, such as Figure 11 and Figure 12 As shown, the connecting groove includes a first groove segment 15243 and a second groove segment 15244 that are connected. The locking block inlet 15241 is located at the beginning of the first groove segment 15243, and the locking block fixing position 15242 is located at the end of the second groove segment 15244. A preset angle S exists between the first groove segment 15243 and the second groove segment 15244, and the preset angle S is greater than or equal to 90°. Figure 11 As shown, when the preset included angle S is greater than 90°, the first groove segment 15243 is inclinedly disposed in one of the assembly walls, and the inclination trend of the first groove segment 15243 is consistent with the spiral trend between the first snap-fit ​​part 1514 and the second snap-fit ​​part 1524. The second groove segment 15244 is connected to the end of the first groove segment 15243 away from the snap-fit ​​inlet 15241, and the second groove segment 15244 extends circumferentially away from the first groove segment 15243. During assembly, the snap-fit ​​can be directly screwed into the connecting groove, and the front shell 11 and the rear shell 12 can be disassembled by screwing the snap-fit ​​out of the connecting groove in the opposite direction. Figure 12As shown, when the preset included angle S is equal to 90°, the first groove segment 15243 extends axially, and the second groove segment 15244 is connected to the end of the first groove segment 15243 away from the card block inlet 15241. The second groove segment 15244 extends circumferentially, that is, the first groove segment 15243 and the second groove segment 15244 form an L-shaped connecting groove. During assembly, the card block is first moved along the first groove segment 15243 and placed in the second groove segment 15244, and then rotated along the second groove segment 15244 to the card block fixing position 15242, thereby realizing the connection of the first screw-on part 151 and the second screw-on part 152. In addition, in order to prevent the card block from disengaging from the connecting groove, a fourth protrusion 15245 is provided in the second groove segment 15244. The user can apply an appropriate force to the card block to remove it from the connecting groove.

[0066] Example 3:

[0067] Based on Example 1 or Example 2, such as Figure 13 As shown, the front shell 11 has a breast-suction part 111 located on one side of the first screw-on part 151 and a connecting part 114 located on one side of the breast-suction part 111 for mounting a bra. The rear shell 12 has a first negative pressure part 121 located on one side of the second screw-on part 152. The breast-suction part 111 extends at least partially into the inner side of the first negative pressure part 121, and the breast-suction part 111 and the first negative pressure part 121 are coaxially arranged. The breast-suction part 111 is provided with a flexible diaphragm 19 that can be elastically deformed. By rotating the first screw-on part 151 and the second screw-on part 152 relative to each other, the breast-suction part 111 and the first negative pressure part 121 will rotate relative to each other. At the same time, the first screw-on part 151 and the first negative pressure part 121 will rotate relative to each other. The helical motion between the second screw joints 152 is converted into relative axial displacement between the two, thereby clamping the flexible diaphragm 19 between the milk suction part 111 and the first negative pressure part 121, achieving a sealed connection between the milk suction part 111, the flexible diaphragm 19, and the first negative pressure part 121. In addition, the flexible diaphragm 19 is directly sleeved on the outside of the milk suction part 111, simplifying the assembly structure of the flexible diaphragm 19, reducing the weight of the wearable breast pump, and making it convenient for users to use the breast pump when they are out. In this embodiment, the flexible diaphragm 19 is thinner and lighter, which helps to increase the space of the negative pressure chamber 1211, thereby increasing the deformation space of the flexible diaphragm 19 and improving the milk suction effect of the wearable breast pump.

[0068] Specifically, such as Figure 13As shown, the front shell 11 also has a bra 4 mounting part 112 located on one side of the breast pumping part 111, and a milk outlet part 113 located between the bra 4 mounting part 112 and the breast pumping part 111. The bra 4 is fitted to the inner side of the bra 4 mounting part 112. The bra 4 has a fitting cavity 41 inside. The breast pumping part 111 has a breast pumping cavity 1111 inside. The fitting cavity 41 communicates with the breast pumping cavity 1111. The milk outlet part 113 has a one-way milk outlet channel 1131 communicating with the milk storage cavity 13 and the breast pumping cavity 1111. The inner side of the first negative pressure part 121 is provided with The breast pump 111 has a negative pressure chamber 1211 facing the milk suction section 111, and the flexible diaphragm 19 is located in the negative pressure chamber 1211. The rear shell 12 is also provided with a negative pressure channel 1212 connecting the breast pump host 2 and the negative pressure chamber 1211. In actual application, the bra 4 fits against the human breast. The breast pump host 2 generates negative pressure in the negative pressure chamber 1211, causing the flexible diaphragm 19 to undergo elastic deformation, that is, the flexible diaphragm 19 expands and deforms, thereby increasing the volume of the deformation chamber and generating negative pressure in the milk suction chamber 1111, thereby simulating the sucking action of an infant and realizing milk suction.

[0069] Optionally, the connecting part 114 is configured as an assembly step, and the bra 4 is fitted and connected at the assembly step, which can improve the connection tightness of the bra 4 and facilitate the user's disassembly and assembly of the bra 4; more preferably, the bra 4 is provided with a bowl-shaped fitting part 40 that fits the breast, and the mounting part 112 of the bra 4 is preferably configured as a conical wall, and the conical wall extends toward the milk storage cavity 13. At least part of the bra 4 is located inside the conical wall, so that the front shell 11 can adapt to the bowl-shaped fitting part 40 in the bra 4. By setting the bowl-shaped fitting part 40, the volume of the fitting cavity 41 is increased, thereby improving the tightness and stability of the bra 4 fitting the breast, allowing the bra 4 to better adhere to the human breast, eliminating the need for a bra to press the bra 4 tightly onto the breast, and optimizing the user's experience.

[0070] Optional, such as Figure 13As shown, the breast-suction part 111 has a first annular extension 115 extending radially on its outer side, and the first negative pressure part 121 has a second annular extension 122 extending axially at one end. The flexible diaphragm 19 has a third annular extension 191 that fits against the first annular extension 115. During assembly, the first screw joint 151 and the second screw joint 152 are rotated relative to each other, causing the breast-suction part 111 and the flexible diaphragm 19 to rotate relative to the first negative pressure part 121. The first annular extension 115 and the second annular extension 122 clamp the third annular extension 191, thereby achieving a sealed connection between the breast-suction part 111, the flexible diaphragm 19, and the first negative pressure part 121. Meanwhile, since the flexible diaphragm 19 is typically made of materials such as silicone... The flexible diaphragm 19 is integrally molded, and its third annular extension 191 can directly serve as a sealing ring between the milk-suction part 111 and the first negative pressure part 121, eliminating the need for an additional sealing ring. This ensures a sealed connection between the milk-suction part 111 and the first negative pressure part 121, simplifies the assembly structure of the flexible diaphragm 19, and reduces the number of accessories in the wearable breast pump, thereby improving the assembly efficiency of the breast pump. In this embodiment, the outer diameters of the first annular extension 115 and the third annular extension 191 can be greater than or equal to the outer diameter of the second annular extension 122 to ensure that the first annular extension 115 and the third annular extension 191 can cover the port of the negative pressure chamber 1211, effectively preventing air leakage from the negative pressure chamber 1211 and ensuring the milk-suction effect of the wearable breast pump.

[0071] Further optional, such as Figure 14 As shown, the outer edge of the third annular extension 191 is provided with a flange 192 facing the first negative pressure part 121. The flange 192 is engaged with the outer periphery of the second annular extension 122 to further improve the sealing between the milk suction part 111, the flexible diaphragm 19 and the first negative pressure part 121. It should be noted that the flange 192 is preferably an annular flange 192, and an annular groove is formed on the side of the flexible diaphragm 19 facing the first negative pressure part 121. Therefore, during the rotational assembly of the first screw joint 151 and the second screw joint 152, the second annular extension 122 can rotate in the annular groove through the rear shell 12. In addition, a clearance cavity 120 communicating with the milk storage cavity 13 is provided between the outer periphery of the second annular extension 122 and the rear shell 12, which can make way for the flange 192 of the first annular extension 115 and the flexible diaphragm 19.

The second negative pressure part 121A is used to install the bra 4, and the bra 4 is equipped with an integrally formed flexible diaphragm 19. In this embodiment, the inner side of the second negative pressure part 121A is provided with a cylindrical cavity 1210 communicating with the outside. The cylindrical cavity 1210 is used to install the bra 4. The bra 4 is an integrally formed structure. When the bra 4 is fitted and installed in the cylindrical cavity 1210, a negative pressure cavity 1211 is formed between the bra 4 and the inner wall of the cylindrical cavity 1210. 211 is provided with a negative pressure channel 1212 connected to the breast pump host 2; in this embodiment, the bra 4 includes a fitting part 40, a milk outlet part 113 and a milk suction part 111 connected in sequence. The bra 4 is provided with a milk suction chamber 1111 that is connected in a communication and a one-way milk outlet channel 1131 that is connected to the milk suction chamber 1111 and the milk storage chamber 13. In this embodiment, the milk suction part 111 is set as a flexible diaphragm 19. At least part of the flexible diaphragm 19 protrudes outward and extends into the negative pressure chamber 1211 to enhance the elastic deformation performance of the flexible diaphragm 19, thereby improving the milk suction effect.

[0074] In this embodiment, the bra 4 has a built-in three-way component, which simplifies the accessory setup of the wearable breast pump device, improves the assembly efficiency of the wearable breast pump device, and facilitates the disassembly and cleaning of the bra 4 and the milk bowl body 1. The bottom of the cylindrical cavity 1210 is provided with a first opening for the milk outlet 113 to pass through, and the top of the cylindrical cavity 1210 is provided with a second opening communicating with the negative pressure channel 1212.
