Description

Technical Field

[0001] This utility model relates to the field of maternal and infant feeding technology, specifically an integrated breast pump and breast shield. Background Technology

[0002] A breast pump is a tool used to express breast milk that has accumulated in the breasts. It is generally suitable for babies who need to be breastfed, especially for mothers who want to breastfeed but still need to continue working. With the help of a breast pump, mothers can express breast milk at work and bring it home to feed their babies after get off work. This can relieve the discomfort of engorgement and increase milk production. Expressing milk in a timely manner is beneficial for the production of new milk.

[0003] Most existing breast pumps have a funnel-shaped suction cup structure that conforms to the skin. These suction cup structures are diverse and vary in structure. In order to thoroughly clean and prevent the accumulation of breast milk in the installation gaps, which can lead to bacterial growth, traditional breast pumps generally include several separate components, such as the funnel cover, suction bowl, cover mounting frame, duckbill valve, and main unit housing. The numerous separate components make cleaning inconvenient and make it difficult to achieve a lightweight design with fewer parts. Moreover, many of these components may fall off or be lost during disassembly and reassembly after cleaning, resulting in re-contamination or loss of parts, which is inconvenient for users.

[0004] To address the above shortcomings, we need to develop an integrated breast shield and breast pump to meet the needs of a wide range of users. Utility Model Content

[0005] In view of the aforementioned problems with existing breast pump suction cup structures, such as numerous parts, inconvenient cleaning, difficult disassembly and assembly, and easy loss or misplacement, the technical solution adopted by this utility model to solve these problems is as follows:

[0006] An integrated breast pump includes a suction cup frame for mounting on a breast pump and a suction cup component for conforming to human skin. The suction cup component is formed on the suction cup frame and has an inlet for milk inflow and an outlet for milk outflow. The inlet is connected to the outlet via a suction channel. The suction channel has a suction bowl structure for performing a suction function, and the suction bowl structure includes a suction deformation part that can undergo elastic deformation.

[0007] The milk suction channel has a channel recess structure arranged around the side wall of the milk suction channel between the milk inlet and the milk outlet. The channel recess structure is recessed from the side wall of the milk suction channel in a direction away from the center of the milk suction channel and in a direction away from the milk inlet.

[0008] The milk suction channel has a channel recess structure between the milk inlet and the milk outlet. The suction deformation part is flexibly connected between the suction bowl structure and the channel recess structure. One end of the suction deformation part is located on the suction bowl structure near the milk inlet, and the other end of the suction deformation part is located on the channel recess structure away from the milk inlet. The outer diameter of the suction bowl structure is smaller than the inner diameter of the channel recess structure.

[0009] The suction deformation part has a first hollow bowl and a second hollow bowl, which are arranged in a direction away from the milk inlet. The first hollow bowl is a hollow hemispherical shape, and the second hollow bowl is a hollow semi-circular flat shape.

[0010] The milk suction channel extends in a direction away from the milk inlet to form an elastic clamping part for easy installation. The side of the elastic clamping part near the suction bowl structure is provided with a rib structure for easy elastic sealing.

[0011] The milk suction channel has a channel recess structure arranged around the side wall of the milk suction channel between the milk inlet and the milk outlet, and the channel recess structure is connected to the milk outlet.

[0012] The suction cup skeleton has a skeleton recess for accommodating the suction cup component. The skeleton recess adopts a first horn cover structure. The milk suction channel has a soft fitting part extending outward near the milk inlet. The soft fitting part adopts a second horn cover structure. The maximum outer diameter of the first horn cover structure is greater than the maximum outer diameter of the second horn cover structure, and the minimum inner diameter of the first horn cover structure is greater than the minimum inner diameter of the second horn cover structure.

[0013] The hardness of the material used for the suction cup skeleton is greater than the hardness of the material used for the suction cup component.

[0014] A breast pump includes a main housing, a suction device installed on the main housing, and a breast shield. The elastic clamping part of the breast shield is detachably connected to the negative pressure chamber of the main housing to form a sealed space. The negative pressure chamber is connected to the suction device. When the breast pumping channel is in a sealed state, the suction device draws air from the negative pressure chamber, causing the suction deformation part to undergo elastic deformation, thereby putting the breast pumping channel into a negative pressure state.

[0015] The suction cup frame has a milk bowl cover at a position away from the suction cup component to facilitate sealing the installation position. The suction cup frame is installed on the milk bowl structure of the main unit housing through the milk bowl cover to form a sealed milk storage cavity. The milk outlet is connected to the milk storage cavity. The milk bowl cover has a milk pouring port at a position away from the suction cup component to allow the milk storage cavity to connect to the outside.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. The breast shield of this utility model integrates the suction cup frame and suction cup components into a single molded piece, and also integrates the suction bowl structure into the milk suction channel of the suction cup components. Compared with the traditional suction cup structure, it reduces the number of disassembled parts and the number of parts that need to be cleaned. Furthermore, the disassembly and assembly process before and after cleaning does not require the disassembly and assembly of numerous parts as in the traditional structure. This reduces the disassembly time before cleaning, improves disassembly efficiency, and also reduces the possibility of parts falling off and being recontaminated after cleaning, thus reducing the possibility of loss and making it more convenient for users.

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] Example 1:

[0027] like Figures 1 to 3 The illustrated integrated breast pump includes a suction cup frame 1 for mounting on a breast pump and a suction cup component 2 for conforming to human skin. The suction cup component 2 has a milk inlet 21 for milk to flow in and a milk outlet 22 for milk to flow out. The milk inlet 21 is connected to the milk outlet 22 through a milk suction channel 23. The milk suction channel 23 has a suction bowl structure 24 for performing suction function. The suction bowl structure 24 includes a suction deformation part 25 that can undergo elastic deformation.

[0028] Specifically, in this embodiment, the suction cup frame 1 is a support frame structure for stable installation on the breast pump and improved support strength. The suction cup frame 1 is preferably made of a rigid rubber material. The suction cup component 2 is a suction cup cover structure for easy sealing and adhesion to the surface of human skin. The suction cup component 2 is preferably made of a soft rubber material. In terms of the hardness of the rubber material, the suction cup frame 1 can preferably be made of a material with a higher hardness than the suction cup component 2. The suction cup component 2 is formed on the suction cup frame 1 by a two-stage injection molding process. The suction cup frame 1 is manufactured before the suction cup component 2. The suction cup component 2 is injection molded. The suction cup component 2 is formed by secondary injection molding and overmolding on the basis of the suction cup frame 1. After overmolding, the suction cup frame 1 and the suction cup component 2 form an integral structure that is fixedly connected. The milk inlet 21 is the entrance for the user to insert the nipple into the suction cup component 2, and the milk outlet 22 is the outlet for the milk to flow into the milk storage position of the breast pump. The milk inlet 21 and the milk outlet 22 are connected by the milk suction channel 23. Therefore, the milk flowing out from the nipple inserted from the milk inlet 21 can flow into the milk outlet 22 through the milk suction channel 23, realizing the normal process of milk collection and storage.

[0029] Based on this, in order to further integrate accessories, save space and reduce volume, the suction bowl structure 24, which facilitates suction, is integrally molded on the side of the milk suction channel 23 away from the milk outlet. The suction bowl structure 24 is flexibly connected to the inner wall of the milk suction channel 23 through the suction deformation part 25, which can undergo elastic deformation. In use, the suction cup 2 is attached to the breast skin, so that the milk suction channel 23 forms a sealed space. The suction device of the breast pump drives the suction bowl structure 24 to cause the suction deformation part 25 to undergo elastic deformation, and a negative pressure state is formed inside the milk suction channel 23. Under the negative pressure state, the milk flows out from the nipple and into the milk suction channel 23, and finally flows into the milk storage position of the breast pump through the milk outlet 22.

[0030] In this embodiment, the breast pump integrates the suction cup frame 1 and the suction cup component 2 into a single molded piece, and also integrates the suction bowl structure 24 into the milk suction channel 23 of the suction cup component 2. Compared with the traditional suction cup structure, this reduces the number of disassembled parts and the number of parts that need to be cleaned. Furthermore, the disassembly and assembly process before and after cleaning does not require the disassembly and assembly of numerous parts as in the traditional structure, which can reduce the disassembly time before cleaning, improve disassembly efficiency, and reduce the possibility of parts falling off and being recontaminated after cleaning, thus reducing the possibility of loss and making it more convenient for users.

[0031] As another embodiment 101 of embodiment 1, the breast pump can be equipped with a one-way duckbill valve 5 at the position of the milk outlet 22 to prevent milk from flowing back after it has flowed out.

[0032] Example 2:

[0033] Based on Example 1, such as Figures 1 to 3 as well as Figure 7 The diagram shows an integrated breast pump shield. The breast pump channel 23 has a recessed structure 26 surrounding the side wall of the breast pump channel 23 between the milk inlet 21 and the milk outlet 22. The recessed structure 26 connects to the milk outlet 22. The recessed structure 26 is an annular recess formed on the side wall of the breast pump channel 23. The recessed structure 26 is recessed from the side wall of the breast pump channel 23 in a direction away from the center of the breast pump channel 23 and away from the milk inlet 21. This recess prevents backflow of milk falling into the recessed structure 26, avoiding milk flowing out of the breast pump channel 23 towards the milk inlet 21. The connection between the recessed structure 26 and the milk outlet 22 facilitates the collection of milk, which is then guided into the milk storage position of the breast pump. Furthermore, the suction deformation part 25 of the suction bowl structure 24 can also be retracted into the recessed space of the recessed structure 26, forming a structure that accommodates the suction bowl connection position, further reducing space and making the structure compact, which helps to reduce the volume of the breast pump shield.

[0034] Example 3:

[0035] Based on Example 2, to further enhance the elastic deformation range of the suction deformation part 25, such as... Figures 1 to 3 as well as Figure 7 The diagram shows an integrated breast pump shield. The breast pump channel 23 has a channel recess structure 26 between the milk inlet 21 and the milk outlet 22. The suction deformation part 25 is flexibly connected between the suction bowl structure 24 and the channel recess structure 26. One end of the suction deformation part 25 is located on the suction bowl structure 24 near the milk inlet 21, and the other end of the suction deformation part 25 is located on the channel recess structure 26 away from the milk inlet 21. The distance of the suction bowl structure 24 near the milk inlet 21 is greater than the distance of the end of the channel recess structure 26 near the milk inlet 21. By setting the two ends of the suction deformation part 25 at different positions, the unfolded area of ​​the suction deformation part 25 is lengthened, and the range of motion of the suction bowl structure 24 is expanded, so that the amplitude of a single suction can be increased. The outer diameter of the suction bowl structure 24 is smaller than the inner diameter of the channel recess structure 26, which facilitates the accommodation of the suction deformation part 25 and provides space for elastic deformation.

[0036] Example 4:

[0037] Based on Example 2, such as Figures 1 to 3 as well as Figure 7The illustrated integrated breast shield has a suction deformation section 25 with a first hollow bowl 241 and a second hollow bowl 242 positioned away from the milk inlet 21. The first hollow bowl 241 is a hollow hemispherical shape, which helps to prevent the nipple from entering the milk suction channel 23, thus preventing the suction bowl structure 24 from accidentally contacting the user's skin during elastic deformation of the suction deformation section 25. Based on this, the second hollow bowl 242 can also be a hollow semi-circular flat shape, with a semi-circular profile in its half-section, to accommodate installation on the suction cup. The negative pressure space on the breast pump prevents interference with other parts. The flat, semi-circular shape narrows the hollow volume, preventing the suction effect from being affected by an excessively large hollow volume. The second hollow bowl 242 is formed on the outside of the first hollow bowl 241 away from the milk inlet 21, which strengthens the first hollow bowl 241's resistance to deformation. This ensures that during suction, the main elastic deformation occurs in the suction deformation part 25, preventing the suction bowl structure 24 from accidentally touching the user's skin when the suction deformation part 25 undergoes elastic deformation, thus facilitating smooth suction.

[0038] Example 5:

[0039] Based on Example 2, in order to facilitate the sealing installation of the breast pump shield in the negative pressure space of the breast pump, such as Figures 1 to 3 as well as Figure 7 The diagram shows an integrated breast pump shield. The breast pump channel 23 extends from the milk inlet 21 to form an elastic clamping part 27 for easy installation. The elastic clamping part 27 and the suction cup part 2 are made of the same soft rubber material. The side of the elastic clamping part 27 near the suction bowl structure 24 is provided with a rib structure 271 for easy elastic sealing. The rib structure 271 extends and protrudes from the side of the elastic clamping part 27 near the suction bowl structure 24. During installation, the elastic clamping part 27 uses the rib structure 271 to elastically wrap around the interface of the negative pressure space inside the breast pump. The tightening force of the elastic deformation causes the rib structure 271 to perform clamping with greater friction. The elastic clamping can achieve a sealing effect with the negative pressure space, avoid air leakage and pressure leakage during the pumping process, and ensure the smooth implementation of the pumping action.

[0040] Example 6:

[0041] Based on Example 1, such as Figures 1 to 3The diagram shows an integrated breast shield. The suction cup frame 1 has a frame recess 11 for accommodating the suction cup component 2. The frame recess 11 adopts a first horn-shaped structure. Specifically, the frame recess 11 extends hollowly from the frame flat portion 14 of the suction cup frame 1 in a direction away from the milk inlet 21 and towards the milk outlet 22. The breast suction channel 23 has a soft fitting portion 28 extending outward near the milk inlet 21. The soft fitting portion 28 adopts a second horn-shaped structure. The root of the suction cup component 2 is located at the end near the frame recess 11. The soft fitting portion 28 extends outward from the root of the suction cup component 2 through the milk inlet 21. In addition, the maximum outer diameter of the first horn-shaped structure is larger than the maximum outer diameter of the second horn-shaped structure, and the minimum inner diameter of the first horn-shaped structure is larger than the minimum inner diameter of the second horn-shaped structure. This facilitates the suction cup component 2 being accommodated in the frame recess 11 and leaves a certain deformation space for the soft fitting portion 28 to elastically deform when it is in contact with the user's skin.

[0042] Example 7:

[0043] Based on any of the above embodiments, such as Figures 4 to 7 The breast pump shown includes a main housing 3, a suction device 4 installed on the main housing 3, and a breast shield. The suction device 4 is an air pump assembly for generating negative pressure suction. The suction device 4 includes an air pump 41 for suction, a control unit 42 for controlling the operation of the air pump 41, and a suction air passage 43 that connects the air pump to the negative pressure chamber 31. The elastic clamping part 27 of the breast shield is detachably connected to the negative pressure chamber 31 of the main housing 3 to form a sealed space. The negative pressure chamber 31 is connected to the air pump 41 of the suction device 4 through the suction air passage 43. When the user fits the breast shield against the breast so that the breast suction channel 23 is in a sealed state, the air pump 41 of the suction device 4 sucks air from the negative pressure chamber 31 through the suction air passage 43, causing the suction deformation part 25 to undergo elastic deformation, so that the breast suction channel 23 enters a negative pressure state. Under the negative pressure state, the milk is forced to flow from the nipple and into the breast suction channel 23, and finally flows into the breast pump's milk storage position through the milk outlet 22.

[0044] Example 8:

[0045] Based on Example 7, such as Figures 4 to 7The illustrated breast pump features a suction cup frame 1 with a milk bowl cover 12 positioned away from the suction cup component 2 for easy sealing. The suction cup frame 1 is injection molded before the milk bowl cover 12. The milk bowl cover 12 is then injection molded onto the suction cup frame 1, forming a fixed, integrated structure. In other words, the suction cup frame 1, suction cup component 2, suction bowl structure 24, and milk bowl cover 12 are sequentially injection molded to form a fixed, integrated structure. The suction cup frame 1, via the milk bowl cover 12, is mounted on the milk bowl structure 32 of the main unit housing 3, forming a sealed milk storage chamber 33. The milk outlet 22 is connected to the milk storage chamber 33 through a one-way duckbill valve 5. The one-way duckbill valve 5 can prevent the milk flowing into the milk storage chamber 33 from flowing back. The milk bowl cover 12 has a milk pouring port 13 at a position away from the suction cup 2, which allows the milk storage chamber 33 to connect to the outside. The flat part 14 of the suction cup frame 1 is spaced apart from the main body housing 3, leaving space for the milk storage chamber 33 to connect to the top milk pouring port 13. After the user finishes pumping the milk, the milk can be poured out from the milk pouring port 13 without disassembling and opening the breast pump cover, further ensuring that the user does not spill the milk during the opening process, making it convenient for the user to operate.

[0046] In addition, users can open the breast pump for internal cleaning after emptying the lotion. The breast pump integrates the suction cup frame 1 and the suction cup component 2 into a single molded piece, and also integrates the suction bowl structure 24 into the milk suction channel 23 of the suction cup component 2. Compared with the traditional suction cup structure, this reduces the number of disassembled parts and the number of parts to be cleaned. Furthermore, the disassembly and assembly process before and after cleaning does not require the disassembly and assembly of numerous parts as in the traditional structure. This reduces disassembly time before cleaning, improves disassembly efficiency, and reduces the possibility of parts falling off and becoming recontaminated after cleaning, thus reducing the possibility of loss and making it more convenient for users.

[0047] 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.
