Description

Technical Field

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

[0002] Breast pumps are increasingly used as an important tool to help breastfeeding women express breast milk. Currently, there are many types of breast pumps on the market, with continuous improvements in function and structure, such as progress in suction efficiency and ergonomic design. However, existing breast pumps still have significant shortcomings in terms of monitoring milk expression.

[0003] Traditional breast pumps typically use opaque materials for their casings, making it difficult for breastfeeding mothers to clearly observe the pumping process and confirm that the nipple is correctly positioned. Sometimes, they may even need to rely on an additional light source or repeatedly adjust their position to achieve alignment. This not only increases the difficulty of use and reduces pumping efficiency but may also affect the continuity of breastfeeding and the mother's comfort.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] This invention addresses the shortcomings of traditional breast pumps in observing milk expression, which make it difficult for breastfeeding mothers to clearly observe the milk expression process and confirm whether the nipple is correctly positioned.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A breast pump, comprising: A milk bowl, comprising a front shell and a rear shell connected together, which together form the milk storage cavity; A breast shield, the breast shield being connected to the front shell of the milk bowl, the breast shield including a shield end and a suction end communicating with each other, the suction end communicating with the milk storage cavity; A main unit assembly, wherein the main unit assembly is disposed between the front shell of the milk bowl and the end of the breast shield; The breast-suction end, as well as the upper areas of the front and rear shells of the milk bowl, are made of a light-transmitting material.

[0007] As described above, the breast pump has a main unit mounting cavity and a breast shield mounting cavity in the front shell of the milk bowl. The main unit assembly is at least partially assembled into the main unit mounting cavity, and the milk suction end is assembled into the breast shield mounting cavity. The main unit assembly has a negative pressure output end that communicates with the breast shield mounting cavity.

[0008] As described above, in a breast pump, the main unit mounting cavity is located above the bra mounting cavity and extends circumferentially around the bra mounting cavity, and the bra mounting cavity extends toward the milk storage cavity along the mounting direction of the milk suction end.

[0009] As described above, the 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.

[0010] As described above, in a breast pump, the first cavity, the bra mounting cavity, and the second cavity are distributed along the width direction of the milk bowl.

[0011] As described above, in a breast pump, the main unit assembly and the milk bowl are detachably connected. The main unit assembly has a first connecting part on its exterior and a second connecting part corresponding to the first connecting part is provided inside the main unit mounting cavity.

[0012] In the breast pump described above, in the first connecting part and the second connecting part, one connecting part is configured as a first slot, and the other connecting part is configured as a first block adapted to the first slot, and the first block and the first slot extend circumferentially in correspondence.

[0013] As described above, in a breast pump, the first connecting part includes a drive member disposed within the main unit assembly and a second locking block connected to the drive member. The second connecting part includes a second locking groove disposed within the main unit mounting cavity. The second locking block can be telescopically moved relative to the outer wall of the main unit assembly by means of the drive member, so that the second locking block can engage or disengage with the second locking groove.

[0014] As described above, the main unit mounting cavity is further provided with a guide groove located on one side of the second slot. The guide groove extends from the opening of the main unit mounting cavity toward the second slot, and the width of the guide groove gradually decreases along the mounting direction of the main unit assembly.

[0015] In the breast pump described above, the front shell of the milk bowl, the rear shell of the milk bowl, and the breast shield are all made of a light-transmitting material.

[0016] Compared with the prior art, the beneficial effects of this utility model are: The breast pump of this invention features a light-transmitting design for the suction end and the upper areas of the front and rear shells of the milk bowl. This allows the internal structure of the suction end to be visualized, enabling users to easily observe the nipple placement and actual milk expression by simply looking down. This eliminates the need for repeated adjustments to posture or disassembly of the pump, effectively addressing the limitations of traditional breast pumps in terms of visibility and difficulty in low-light conditions. This significantly improves the ease of use and makes the pumping process smoother. Furthermore, the light-transmitting parts allow users to immediately detect abnormalities such as milk leakage, spillage, or blockages in the suction components. This is especially beneficial for wearable breast pump users, allowing them to check for these issues without removing the pump, reducing clothing contamination and interruptions to the pumping process.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] 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.

[0021] 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.

[0022] Example 1: like Figures 1 to 14 As shown, this utility model provides a breast pump, including a milk bowl 1, a breast shield 2, and a main unit assembly 3. The milk bowl 1 includes a front shell 11 and a rear shell 12 connected to each other, forming a milk storage chamber 101. The breast shield 2 is connected to the front shell 11 and includes a breast shield end 21 and a breast suction end 22 that are connected to each other. The breast suction end 22 is connected to the milk storage chamber 101. The main unit assembly 3 is located between the front shell 11 and the breast shield end 21. The breast suction end 22 and the upper part of the front shell 11 and the rear shell 12 are made of a light-transmitting material.

[0023] In this invention, by making the upper areas of the breast pump end 22, the front shell 11 of the breast cup, and the rear shell 12 of the breast cup translucent, the interior of the breast pump end 22 is made visible. When using the breast pump, the user can simply look down to clearly observe the nipple placement and actual milk expression inside the breast pump end 22 without having to repeatedly adjust their posture or disassemble the breast pump. This effectively improves the problems of insufficient visibility and difficulty in observation in low-light environments in traditional breast pumps, greatly enhancing the convenience of operating the breast pump and making the milk expression process smoother. At the same time, the user can detect abnormal conditions such as milk leakage, milk spillage, and blockage of the breast pump components through the translucent part of the breast pump in the first instance. Especially for users of wearable breast pumps, they can check without removing the breast pump, reducing the trouble of clothing contamination and interruption of milk expression.

[0024] Optionally, the upper regions of the breast suction end 22, the front shell 11 of the breast cup, and the rear shell 12 of the breast cup are made of transparent material. In practical applications, the breast cup 1 can be made of transparent materials such as polypropylene and polyethersulfone, and the breast suction cover 2 can be made of transparent materials such as transparent silicone and transparent thermoplastic elastomer.

[0025] Specifically, such as Figure 4 and Figure 10 As shown, the main unit assembly 3 and the breast shield 2 are respectively connected to the front shell 11 of the milk bowl. The breast suction end 22 passes through the main unit assembly 3 and is connected to the milk bowl 1. The breast suction end 22 is connected to the milk storage chamber 101. The breast shield end 21 is located outside the milk bowl 1 and is clamped and fixed to the main unit assembly 3 by the breast shield end 21 and the milk bowl 1 to improve the installation stability of the main unit assembly 3 and ensure the normal operation of the breast pump. In practical applications, the breast shield end 21 can fit against the human chest, and the nipple can be inserted into the breast suction end 22. The main unit assembly 3 creates 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 into the milk storage chamber 101 through the breast suction end 22. It should be noted that in this utility model, the main unit assembly 3 includes a main unit housing and a breast pump device disposed in the main unit housing. 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.

[0026] 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.

[0027] Further optional, such as Figure 4 and Figure 8As shown, the front shell 11 and the rear shell 12 of the milk bowl are detachably fixedly connected to facilitate the all-round cleaning of the milk bowl 1.

[0028] In some alternative embodiments, such as Figure 2 , 4 As shown in Figures 8 and 10, the front shell 11 of the milk bowl is provided with a main unit mounting cavity 102 and a breast shield mounting cavity 103. The main unit mounting cavity 102, the breast shield mounting cavity 103, and the milk storage cavity 101 can be separated by the structure of the front shell 11 itself. The main unit assembly 3 is at least partially assembled into the main unit mounting cavity 102, and the milk suction end 22 is assembled into the breast shield mounting cavity 103. In this embodiment, the main unit assembly 3 is configured as a built-in main unit, 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. Furthermore, in practical applications, the... The main unit assembly 3 and the breast shield 2 are sequentially assembled into the front shell 11 of the breast cup. The breast shield end 21 at least partially abuts against the front side of the main unit assembly 3. The main unit assembly 3 can be fixed in the main unit mounting cavity 102 by the breast shield end 21 and the breast cup 1, which helps to improve the connection stability of the main unit assembly 3 and ensure the normal operation of the breast pump. In addition, the main unit assembly 3 is installed in the upper part of the front shell 11 of the breast cup. In actual application, the main unit assembly 3 faces the user, which is convenient for the user to operate the main unit assembly 3. At the same time, combined with the visual design of the breast shield end 22, it is even more convenient for the user to operate the main unit assembly 3 to adjust the breast pump.

[0029] Furthermore, the main unit assembly 3 is provided with a negative pressure output terminal 301 communicating with the bra mounting cavity 103. The main unit assembly 3 can draw air from the bra mounting cavity 103 through the negative pressure output terminal 301, thereby generating a pressure change in the breast suction end 22 to simulate the action of an infant sucking on the mother's breast, thereby improving breast suction efficiency; Figure 2 , 5 As shown in Figures 8 and 11, 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 assembly 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 pumping device.

[0030] Furthermore, such as Figure 2 , 5As shown in Figures 8 and 11, the breast-suction end 22 is provided with a breast-suction channel 221 communicating with the milk storage cavity 101, and the mother's nipple can extend into the breast-suction channel 221. Optionally, the breast-suction channel 221 can be directly connected to the bra end 21 and the bra mounting cavity 103. Alternatively, the breast-suction end 22 can be configured as a breast-suction end 22 with an elastic diaphragm, and the breast-suction channel 221 is located inside the breast-suction end 22 and separated from the bra mounting cavity 103 by the elastic diaphragm. The negative pressure can be generated in the bra mounting cavity 103 by the negative pressure output end 301, causing the elastic diaphragm to expand and deform outward, further generating negative pressure in the breast-suction channel 221, thereby prompting the breast to output breast milk.

[0031] Optionally, the longitudinal cross-section of the milk bowl 1 is approximately circular, which helps to reduce the overall volume of the breast pump, making it easier for users to wear and use, improving the wearing comfort of the breast pump, and at the same time increasing the space capacity of the milk storage chamber 101, thereby increasing the milk supply of the breast pump.

[0032] Further optional, such as Figure 4 and Figure 8 As shown, the main unit assembly 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 assembly 3 from obstructing the bra mounting cavity 103. This ensures that the breast pump end 22 can be accurately aligned with the bra mounting cavity 103 through the clearance opening 302 during installation, and ensures that the breast pump 2 is accurately assembled in the bra mounting cavity 103, making it convenient for users to install and remove the breast pump 2. Furthermore, the breast pump end 21 at least partially abuts against the outside of the main unit assembly 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 assembly 3 in the main unit mounting cavity 102 through the breast pump 2, improving the connection stability of the main unit assembly 3, thereby improving the output stability of negative pressure.

[0033] On the other hand, in order to facilitate the disassembly and assembly of the main unit assembly 3 and the milk bowl 1, the main unit assembly 3 and the milk bowl 1 are detachably connected. The main unit assembly 3 is provided with a first connecting part 303 on the outside, and a second connecting part 104 corresponding to the first connecting part 303 is provided in the main unit mounting cavity 102. The corresponding connection makes the main unit assembly 3 and the milk bowl 1 detachably connected. Users can directly plug and unplug the main unit assembly 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 assembly 3 and the milk bowl 1, and facilitate the cleaning of the milk bowl 1.

[0034] Example 2: Based on the above embodiment one, this embodiment two provides an optional embodiment of the host mounting cavity 102, such as... Figures 2 to 4 As shown, the main unit mounting cavity 102 is located above the bra mounting cavity 103 and extends circumferentially around the bra mounting cavity 103. The bra mounting cavity 103 extends towards the milk storage cavity 101 along the installation direction of the milk suction end 21. In this embodiment, the main unit mounting cavity 102 is configured as an integral arc-shaped cavity. The main unit assembly 3 is at least partially fitted into the arc-shaped cavity, which helps to increase the space capacity of the main unit mounting cavity 102 and accommodate a larger main unit assembly 3. At this time, the main unit assembly 3 is installed on the upper part of the front shell 11 of the milk bowl. Furthermore, at least part of the outer wall of the bra mounting cavity 103 extends out of the main unit mounting cavity 102 along the installation direction of the milk suction end 21, avoiding the main unit assembly 3 from blocking the milk suction end 22 from above, ensuring that the user can observe the situation inside the milk suction end 22 through the light-transmitting parts in the milk suction end 21, the front shell 11 of the milk bowl, and the rear shell 12 of the milk bowl by looking down.

[0035] Example 3: Based on the above embodiment one, this embodiment three provides another optional embodiment of the host mounting cavity 102. The difference between this embodiment three and the above embodiment two is that, as Figures 8 to 11 As shown, the main unit mounting cavity 102 includes a first cavity 1021 and a second cavity 1022 located on both sides of the bra mounting cavity 103. The main unit assembly 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 103. The breast pumping device in the main unit assembly 3 is also respectively located in the first cavity 1021 and the second cavity 1022 located on the left and right sides of the bra mounting cavity 103. This can prevent the main unit assembly 3 from blocking the breast pump end 22 from above, increase the light-transmitting part in the breast pump, thereby widening the user's visual range and ensuring that the user can observe the situation inside the breast pump end 22 through the light-transmitting part in the breast pump by looking down.

[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 negative pressure pump in the breast pumping device can be adjusted according to the position of the connecting port 111. This utility model does not make specific limitations.

[0037] Example 4: Based on any of the embodiments one to three above, this embodiment four provides an optional embodiment of the first connecting part 303 and the second connecting part 104, such as... Figure 2 , 3 As shown in Figure 6, in the first connecting part 303 and the second connecting part 104, one connecting part is configured as a first slot 3031a, and the other connecting part is configured as a first block 1041a adapted to the first slot 3031a. At least one set of the first block 1041a and the first slot 3031a are provided correspondingly, and the first block 1041a and the first slot 3031a extend circumferentially in a corresponding manner. By configuring the first connecting part 303 and the second connecting part 104 as a snap-fit ​​structure, the connection structure between the main unit assembly 3 and the milk bowl 1 is simplified, thereby facilitating the assembly and disassembly of the main unit assembly 3 in the milk bowl 1. In practical applications, using... Users can directly grasp one end of the main unit assembly 3 and plug it into the main unit mounting cavity 102. During this plugging and unplugging process, the first locking block 1041a and the first locking groove 3031a directly engage or separate under force, making it easy for users to disassemble and assemble the breast pump. The first connecting part 303 and the second connecting part 104 have simple structures, reducing the production cost of the breast pump. At the same time, the first locking block 1041a and the first locking groove 3031a can be respectively set as an arc-shaped locking block and an arc-shaped locking groove structure, which helps to increase the engagement area of ​​the first connecting part 303 and the second connecting part 104, thereby improving the connection stability between the main unit assembly 3 and the milk bowl 1.

[0038] Example 5: Based on any of the embodiments one to three above, this embodiment five provides another optional embodiment of the first connecting part 303 and the second connecting part 104. The difference between this embodiment five and the above embodiment four is that, as Figures 12 to 14As shown, the first connecting part 303 includes a driving member 30311b disposed within the main unit assembly 3 and a second locking block 30312b connected to the driving member 30311b. The second connecting part 104 includes a second locking groove 1041b disposed within the main unit mounting cavity 102. The second locking block 30312b can be telescopically moved relative to the outer wall surface of the main unit assembly 3 via the driving member 30311b, so that the second locking block 30312b can engage or disengage from the second locking groove 1041b. In this embodiment, the main unit assembly 3 has an external surface facing... The drive member 30311b has a recessed receiving cavity inside, and the second locking block 30312b is fixedly disposed on the top of the drive member 30311b. The second locking block 30312b can compress the drive member 30311b under force, causing the drive member 30311b to undergo compression deformation. This allows the drive member 30311b to move the second locking block 30312b into the receiving cavity. At this time, the main unit assembly 3 can be inserted into the main unit mounting cavity 102. When the second locking block 30312b is in contact with the second locking slot... When 1041b is aligned, the second locking block 30312b can extend into the outside of the receiving cavity by the rebound of the driving member 30311b and engage with the second locking slot 1041b, thereby realizing the assembly of the main unit assembly 3; when disassembling the main unit assembly 3, the user can directly pull the main unit assembly 3 out of the main unit mounting cavity 102, and the second locking block 30312b can retract into the receiving cavity under force, thereby realizing the disassembly of the main unit assembly 3; optionally, the driving member 30311b and the second locking block 30312b can be set as elastic positioning in the prior art. The bead module has a simple structure, which helps to reduce the production cost of the breast pump. Furthermore, the elastic positioning bead module can be installed in the main unit assembly 3 through the mounting bracket 30313b. The positioning bead 3031 protrudes from the outside of the mounting bracket 30313b, and the diameter of the port through which the positioning bead 3031 passes in the mounting bracket 30313b 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 30313b to restrict the positioning bead 3031 from leaving the main unit assembly 3, so as to avoid the failure of the elastic positioning bead module.

[0039] Furthermore, such as Figure 12As shown, the main unit mounting cavity 102 is also provided with a guide groove 1042b located on one side of the second slot 1041b. The guide groove 1042b extends from the opening of the main unit mounting cavity 102 toward the second slot 1041b. The guide groove 1042b can guide the second locking block 30312b to move into the second slot 1041b, so as to facilitate the precise connection between the main unit assembly 3 and the milk bowl 1. At the same time, the width of the guide groove 1042b is along the assembly of the main unit assembly 3. As the direction gradually decreases, in practical applications, the second locking block 30312b can be engaged into the guide groove 1042b through the cavity opening of the host mounting cavity 102, and move along the guide groove 1042b toward the second locking slot 1041b. During this process, the second locking block 30312b can be gradually driven by the inner wall of the host mounting cavity 102 to compress the driving member 30311b, thereby causing the second locking block 30312b to retract into the host assembly 3, avoiding assembly jamming or inability to assemble the host assembly 3.

[0040] Example 6: Based on any of the above embodiments one to five, this sixth embodiment provides another optional embodiment of the breast pump. 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.

[0041] 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.
