[0002] As a key tool to assist breastfeeding women in collecting breast milk, the use of breast pumps is continuously increasing with the popularization of breastfeeding concepts and the improvement of maternal and infant care needs. Traditional breast pumps are usually made of opaque materials, which limits the visible area and narrows the viewing angle. This makes it difficult for mothers to clearly observe the milk collection status and confirm the correct nipple position during use. Sometimes, they even need to use an additional light source or repeatedly adjust their posture to achieve alignment. This undoubtedly increases the difficulty of use, reduces the efficiency of milk collection, and may also affect the continuity of breastfeeding and the mother's comfort.

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

[0004] This invention addresses the problem that traditional breast pumps, as mentioned above, typically use opaque materials for their outer shells, resulting in limited visibility and a narrow viewing angle. This makes it difficult for mothers to clearly observe the milk collection process and confirm the correct nipple position, thus reducing pumping efficiency. The invention proposes a new type of breast pump.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A breast pump includes a milk bowl, a breast shield connected to the milk bowl, and a main unit, wherein the milk bowl has a milk storage chamber.

The breast pump is connected to the milk bowl through the breast pump mounting cavity. The upper part of the milk bowl is provided with an observation window, and the milk bowl has a user line of sight from the observation window to the breast pumping channel. Along the user line of sight, at least the observation window, the upper part of the breast pump, and the top wall of the breast pump mounting cavity are made of a light-transmitting material.

[0006] In the breast pump described above, the viewing window is configured as a convex lens, with the protruding portion of the convex lens facing outwards from the milk bowl.

[0007] In the breast pump described above, the convex lens is integrally formed with the milk bowl; or, the convex lens is ultrasonically welded into the milk bowl.

[0008] As described above, the non-observation window portion of the milk bowl in the breast pump has a blurred light-transmitting area.

[0009] As described above, the breast pump includes a breast shield end and a breast suction end that communicate with each other. The breast suction end is fitted into the breast shield mounting cavity, the breast suction channel is located inside the breast suction end, and the breast shield end at least partially abuts against the outside of the main unit.

[0010] As described above, the breast pump also includes a main unit mounting cavity in the milk bowl, which is located on one side of the user's line of sight. The main unit is at least partially assembled into the main unit mounting cavity, and the main unit has a negative pressure output end that communicates with the bra mounting cavity.

[0011] As described above, the breast pump's main unit mounting cavity includes a first cavity and a second cavity located on both sides of the bra mounting cavity, and the negative pressure output end is connected to the bra mounting cavity through the first cavity or the second cavity.

[0012] As described above, the first cavity, the bra mounting cavity, and the second cavity are distributed along the width direction of the milk bowl.

[0013] As described above, the breast pump has a detachable connection between the main unit and the milk bowl. The main unit has a first connecting part on its exterior and a second connecting part corresponding to the first connecting part inside the main unit's mounting cavity.

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.

[0021] Example 1: like Figures 1 to 7As shown, this utility model provides a breast pump, including a milk bowl 1, a breast shield 2 and a main unit 3 respectively connected to the milk bowl 1. The milk bowl 1 has a milk storage chamber 101; the main unit 3 is located between the breast shield 2 and the milk bowl 1; the breast shield 2 has a milk suction channel 201 communicating with the milk storage chamber 101; the milk bowl 1 has a breast shield mounting cavity 103, and the breast shield 2 is connected to the milk bowl 1 through the breast shield mounting cavity 103; the upper part of the milk bowl 1 has an observation window 4, and the milk bowl 1 has a user's line of sight from the observation window 4 to the milk suction channel 201. Along the user's line of sight, at least the observation window 4, the upper part of the breast shield 2 and the top wall of the breast shield mounting cavity 103 are made of a light-transmitting material.

[0022] In this invention, the breast pump features an observation window 4 on the upper part of the milk bowl 1, creating a user's line of sight from the observation window 4 to the milk suction channel 201. When using the breast pump, the user can simply look down and clearly observe the nipple placement and actual milk suction within the milk suction channel 201 through the observation window 4, enhancing the visualization of the milk suction process and improving the convenience of wearing and operating the breast pump. The user can better control the operation of the breast pump and adjust the negative pressure based on the actual milk suction situation, making the milk suction process smoother and improving efficiency. Furthermore, along the user's line of sight, the observation window 4, the upper part of the breast shield 2, and the top wall of the breast shield mounting cavity 103 are made of a light-transmitting material, preventing the milk bowl 1 and the breast shield 2 from obstructing the milk suction channel 201, ensuring the visualization of the milk suction channel 201, and further optimizing the visualization effect of the milk suction channel 201.

[0023] Optionally, the milk bowl 1 can be made entirely of a transparent material; in practical applications, the milk bowl 1 can be made of transparent materials such as polypropylene and polyethersulfone, and this utility model does not make any specific limitations.

[0024] Furthermore, such as Figure 1 As shown, the observation window 4 is set along the outer contour of the milk bowl 1, which allows the observation window 4 to fit better into the overall structure of the milk bowl 1, maximize the use of the observable area on the surface of the milk bowl 1, expand the breadth of the observation field, and allow the mother to clearly capture the nipple position and milk flow in the milk suction channel 201 from more angles; at the same time, it can make the appearance of the breast pump more beautiful and simple.

[0025] In some alternative embodiments, the viewing window 4 may be configured as a transparent cover.

[0026] In some alternative embodiments, the observation window 4 is configured as a convex lens, with the protruding portion of the convex lens facing the outside of the milk bowl 1; specifically, the convex lens has a structure that is thick in the middle and thin at the edges, which can focus and magnify the internal situation of the milk suction channel 201, further reducing the difficulty of visually observing the milk suction channel 201, allowing the mother to clearly observe whether the nipple is in the optimal milk suction position and whether the milk collection is smooth, thereby more accurately adjusting the wearing and milk suction of the breast pump and improving milk suction efficiency.

[0027] In an optional embodiment of the convex lens, the convex lens and the milk bowl 1 are integrally molded, which avoids connection gaps between the two. This not only enhances the stability and robustness of the overall structure, reduces the risk of the convex lens loosening or falling off, and extends the service life of the milk bowl 1, but also improves the sealing performance of the milk bowl 1, effectively preventing breast milk leakage at the connection between the convex lens and the milk bowl 1, ensuring cleanliness and hygiene during the breastfeeding process. Simultaneously, the integral molding of the convex lens and the milk bowl 1 eliminates the need for separate convex lens installation, simplifies the production process, reduces assembly errors, and helps improve production efficiency and product qualification rate, thereby reducing production costs to some extent. For users, the integral molding structure makes the observation window 4 and the milk bowl 1 form a complete unit, with a simpler and smoother appearance. Cleaning also eliminates the need to consider the dead corners after disassembly, making it convenient and quick, further enhancing ease of use. Optionally, the milk bowl 1 can be made of polycarbonate (PC) material, and during the production process, the milk bowl 1 and the observation window 4 can be integrally injection molded.

[0028] In another optional embodiment of the convex lens, the convex lens is ultrasonically welded into the milk bowl 1. Ultrasonic welding technology enables the convex lens and the milk bowl 1 to form a tight and firm connection with high connection strength, which can effectively resist the influence of external forces such as vibration during milk expression and disassembly and cleaning, reduce the risk of the convex lens loosening or falling off, and ensure the long-term stable use of the breast pump. At the same time, this connection method can achieve a seamless fit between the convex lens and the milk bowl 1, greatly improving the sealing performance of the milk bowl 1, preventing breast milk from leaking from the connection between the convex lens and the milk bowl 1, and ensuring a clean and hygienic milk expression environment.

[0029] In some alternative embodiments, such as Figure 1As shown, the non-observation window 4 portion of the milk bowl 1 is provided with a blurred light-transmitting area 121. In this embodiment, the milk bowl 1 as a whole can be made of transparent material, which helps to simplify the production process of the milk bowl 1. In order to improve the privacy of the user during the breastfeeding process and enhance the aesthetics of the milk bowl 1, the non-observation window 4 portion of the milk bowl 1 can be subjected to surface texturing blurring treatment during the production process to form the blurred light-transmitting area 121. At the same time, the observation window 4 is located in the blurred light-transmitting area 121 and close to the top of the milk bowl 1 to ensure the visibility of the breastfeeding channel 201.

[0030] Alternatively, since the milk bowl 1 is a shell structure, in order to further enhance the visual effect of the blurred light-transmitting area 121, the non-observation window 4 areas of the inner and outer walls of the milk bowl 1 can be subjected to surface texturing blurring treatment to form the blurred light-transmitting area 121.

[0031] On the other hand, in some embodiments, such as Figure 4 As shown, the breast shield 2 includes a connected shield end 21 and a breast suction end 22. The breast suction end 22 is assembled into the breast shield mounting cavity 103. The breast suction channel 201 is located inside the breast suction end 22, and the shield end 21 at least partially abuts against the outside of the main unit 3. The main unit 3 is clamped and fixed by the shield end 21 and the milk bowl 1 to improve the installation stability of the main unit 3 and ensure the normal operation of the breast pump. In practical applications, the shield end 21 can fit against the human chest, and the nipple can be inserted into the breast suction end 22. The main unit 3 generates negative pressure in the breast suction end 22 to promote the output of breast milk from the mother's breast in a negative pressure environment. The output breast milk can flow through the breast suction end 22 into the milk storage cavity 101. It should be noted that in this utility model, the main unit 3 includes a main unit shell and a breast pump device disposed inside the main unit shell. The breast pump device integrates a breast pump module and a corresponding control module as in the prior art. The user can control the operation of the breast pump module through the control module, thereby realizing the operation of the breast pump. This will not be elaborated further here.

[0032] Another option, such as Figure 4As shown, the breast shield 2 can be configured as a breast shield 2 with an elastic diaphragm, that is, the breast suction end 22 can be configured as an elastic diaphragm, which surrounds the breast suction channel 201 to form the breast suction channel 201. In practical applications, the elastic diaphragm undergoes elastic deformation under the negative pressure environment in the breast shield mounting cavity 103, so as to generate negative pressure in the breast suction channel 201, so as to promote the output of breast milk from the mother's breast under negative pressure environment, which is conducive to realizing the action of the breast shield 2 simulating the sucking of the nipple by the baby and improving the breast suction efficiency. In this embodiment, at least the breast suction end 22 is made of a light-transmitting material to prevent obstruction of the breast suction channel 201. Further optionally, the breast shield 2 can be made of transparent materials such as transparent silicone or transparent thermoplastic elastomer.

[0033] Furthermore, such as Figure 5 and Figure 6 As shown, the milk bowl 1 also has a main unit mounting cavity 102, which is located on one side of the user's line of sight. The main unit 3 is at least partially assembled into the main unit mounting cavity 102. The main unit 3 has a negative pressure output end 301 that communicates with the breast shield mounting cavity 103. In this embodiment, the main unit 3 is configured as a built-in main unit 3, which can be assembled into the milk bowl 1 through the main unit mounting cavity 102, making the overall structure of the breast pump more compact and reducing the size of the breast pump. At the same time, the main unit mounting cavity 102 is located on one side of the user's line of sight to prevent the main unit 3 from obstructing the milk expression channel 201 from above, ensuring the visibility of the milk expression channel 201. Furthermore, in practical applications, the side of the milk bowl 1 facing the user is designated as the front side, and the side away from the user is designated as the rear side. The main unit 3 and the breast shield 2 are assembled sequentially from the front side of the milk bowl 1. During assembly, the bra end 21 at least partially abuts against the front side of the main unit 3. The main unit 3 can be fixed within the main unit mounting cavity 102 via the bra end 21 and the milk bowl 1, which improves the connection stability of the main unit 3 and ensures the normal operation of the breast pump. Furthermore, the main unit 3 is mounted on the upper part of the front side of the milk bowl 1, facing the user in practical applications, facilitating user operation. Combined with the visual design of the milk suction channel 201, this further allows the user to adjust the operation of the breast pump based on the actual milk suction situation and the user's wearing condition. Additionally, the main unit 3 can draw air from the bra mounting cavity 103 via the negative pressure output end 301, causing changes within the bra mounting cavity 103 and further creating pressure changes within the milk suction channel 201, simulating the action of infant sucking and thus improving milk suction efficiency. Figure 5As shown, the milk bowl 1 has a connecting port 111 that connects the main unit mounting cavity 102 and the bra mounting cavity 103. When the main unit 3 is installed in the main unit mounting cavity 102, the negative pressure output terminal 301 is aligned with the connecting port 111 to connect to the bra mounting cavity 103. It should be noted that the negative pressure output terminal 301 can be understood as the output terminal of the breast pump.

[0034] Further optional, such as Figures 2 to 5 As shown, the main unit 3 is provided with a clearance opening 302 for the breast pump end 22 to pass through. The clearance opening 302 is coaxially arranged with the bra mounting cavity 103, which can prevent the main unit 3 from obstructing the bra mounting cavity 103, ensuring that the breast pump end 22 can be accurately aligned with the bra mounting cavity 103 through the clearance opening 302 when installed, and ensuring that the breast pump 2 is accurately assembled in the bra mounting cavity 103, making it convenient for users to install and disassemble the breast pump 2. Furthermore, the breast pump end 21 at least partially abuts against the outside of the main unit 3. When the user uses the breast pump, it can provide a stable support point for the breast pump 2, preventing the breast pump 2 from shifting or shaking due to negative pressure or external force during breast pumping, ensuring the sealing of the breast pump end 21 against the breast, and also tightening and fixing the main unit 3 in the main unit mounting cavity 102 through the breast pump 2, improving the connection stability of the main unit 3, thereby improving the output stability of negative pressure.

[0035] In some alternative embodiments, such as Figure 3 , 5 As shown in Figure 6, the host mounting cavity 102 includes a first cavity 1021 and a second cavity 1022 located on both sides of the bra mounting cavity 103. The host 3 is at least partially adapted to the first cavity 1021 and the second cavity 1022, and the first cavity 1021, the bra mounting cavity 103, and the second cavity 1022 are distributed along the width direction of the milk bowl 1. In this embodiment, the first cavity 1021 and the second cavity 1022 are respectively located on the left and right sides of the breast pump mounting cavity. At the same time, the components of the breast pumping device in the host 3 are respectively located in the first cavity 1021 and the second cavity 1022 on the left and right sides of the bra mounting cavity 103. This can prevent the host 3 from blocking the breast pumping end 22 and the observation window 4, ensuring that the user can observe the situation inside the breast pumping end 22 through the user's line of sight by looking down. It also increases the visualization area above the breast pumping channel 201, widens the user's visual range, and further facilitates the user to directly observe the situation inside the breast pumping channel 201.

[0036] Furthermore, the negative pressure output terminal 301 is connected to the bra mounting cavity 103 through the first cavity 1021 or the second cavity 1022. In this embodiment, the connecting port 111 can be located between the first cavity 1021 and the bra mounting cavity 103, or between the second cavity 1022 and the bra mounting cavity 103. The negative pressure output terminal 301 can be installed in the first cavity 1021 or the second cavity 1022 according to the position of the connecting port 111. That is, the breast pump in the breast pumping device can be adjusted according to the position of the connecting port 111.

[0037] On the other hand, to facilitate the assembly and disassembly of the main unit 3 and the milk bowl 1, such as Figure 2 , 6 As shown in Figure 7, the main unit 3 and the milk bowl 1 are detachably connected. The main unit 3 has a first connecting part 303 on its exterior, and the main unit mounting cavity 102 has a second connecting part 104 corresponding to the first connecting part 303. Users can directly plug and unplug the main unit 3 and the milk bowl 1 through the first connecting part 303 and the second connecting part 104 to easily disassemble and assemble the main unit 3 and the milk bowl 1, and facilitate the cleaning of the milk bowl 1.

[0038] Further optionally, the first connecting part 303 and the second connecting part 104 can be configured as a matching block and slot mating structure, or the first connecting part 303 can be configured as an elastic positioning bead module, and the second connecting part 104 can be correspondingly configured as a groove adapted to the elastic positioning bead 3031, thereby realizing the detachable connection between the main unit 3 and the milk bowl 1, which is beneficial for users to disassemble and assemble the milk bowl 1 and the main unit 3.

[0039] The elastic positioning bead module can be configured with reference to existing technology, such as... Figure 7As shown, the elastic positioning bead module includes a positioning bead 3031 and an elastic element 3032 connected to the positioning bead 3031. The elastic element 3032 is disposed inside the main unit 3. The positioning bead 3031 is fixedly disposed on the top of the elastic element 3032 and protrudes from the outside of the main unit 3. When the main unit 3 is assembled into the milk bowl 1, the positioning bead 3031 can be driven by the inner wall of the main unit mounting cavity 102 to compress the elastic element 3032, so that the positioning bead 3031 retracts into the main unit 3. When the positioning bead 3031 moves with the main unit 3 to correspond to the groove in the main unit mounting cavity 102, the positioning bead 3031 can rebound through the elastic element 3032 and engage with the groove. Furthermore, the elastic positioning bead module can be installed inside the host 3 via a mounting bracket 3033. The positioning bead 3031 protrudes from the outside of the mounting bracket 3033, and the diameter of the port through which the positioning bead 3031 passes in the mounting bracket 3033 is slightly smaller than the outer diameter of the positioning bead 3031, so as to form a limiting structure at the port of the mounting bracket 3033 to restrict the positioning bead 3031 from leaving the host 3, so as to avoid the failure of the elastic positioning bead module.

[0040] Example 2: Based on the above embodiment one, this embodiment two provides an optional implementation of the milk bowl 1, such as... Figures 2 to 4 As shown, the milk bowl 1 includes a front shell 11 and a rear shell 12 connected to each other. The main unit 3 is located between the front shell 11 and the breast pump 2. The observation window 4 is located in the upper part of the rear shell 12. By placing the observation window 4 in the upper part of the rear shell 12, it can be adapted to the visual direction when the user looks down, allowing the user to better monitor the situation inside the breast pumping channel 201 using the observation window 4, which facilitates the breast pumping process and adjustments.

[0041] Furthermore, the blurred light-transmitting area 121 is located in the rear shell 12 of the milk bowl, and the blurred light-transmitting area 121 is located on the outer periphery of the observation window 4.

[0042] Furthermore, the front shell 11 and the rear shell 12 of the milk bowl are detachably fixedly connected to facilitate all-round cleaning of the milk bowl 1. When the front shell 11 and the rear shell 12 of the milk bowl are connected, they form the milk storage chamber 101. The milk suction channel 201 is located between the breast suction shield 2 and the front shell 11 of the milk bowl. During assembly, the main unit 3 and the breast suction shield 2 are respectively connected to the front shell 11 of the milk bowl, and the main unit 3 is fixed in the front shell 11 of the milk bowl through the breast suction shield 2, which helps to ensure the normal operation of the breast pump.

[0043] Furthermore, the main unit mounting cavity 102 and the breast shield mounting cavity 103 are respectively located in the front shell 11 of the milk bowl, and the main unit mounting cavity 102, the breast shield mounting cavity 103 and the milk storage cavity 101 are separated by the structure of the front shell 11 of the milk bowl itself; the front shell 11 of the milk bowl, the rear shell 12 of the milk bowl and the breast shield 2 are all made of light-transmitting material, which further increases the visual area in the breast pump, thereby expanding the user's visual range and making it more convenient for the user to observe the placement of the nipple and the milk expression in the breast pump end 22.

[0044] Furthermore, the top of the front shell 11 and the rear shell 12 of the milk bowl are provided with a milk pouring port 13 that communicates with the milk storage chamber 101. The user can directly invert the breast pump so that the breast milk in the milk storage chamber 101 can be poured out through the milk pouring port 13 for the baby to consume.

[0045] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
