[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] During breast pumping, negative pressure is generated inside the mouth to pull the nipple and elongate it, thereby stimulating milk let-down. In related technologies, the milk suction channel on breast pumps is usually a straight tube. However, the size of the milk suction channel of this type of breast pump is larger than the nipple and is straight in shape. Therefore, the straight tube breast pump cannot simulate the actual sucking of a baby, resulting in lower lactation efficiency.

[0040] The milk suction channels in breast pumps typically use a straight-tube design. Their working principle is that the suction force generated by negative pressure during milk expression pulls the nipple, causing it to elongate. Because the size of the milk suction channel is larger than the nipple and the channel is straight, it is impossible to mimic the situation of a baby latching on to milk and create a feeling of envelopment in the nipple during milk expression. This makes it difficult to stimulate the nipple and milk let-down, resulting in low milk production efficiency and a poor user experience.

[0041] Therefore, this embodiment provides a milk-pumping assembly and a breast pump 200. The milk-pumping assembly can improve lactation efficiency.

[0042] Please see Figures 1 to 3 and Figure 9 A breast pump assembly 100, comprising:

[0043] A breast bra 10, wherein a breast suction channel 11 is provided inside the breast bra 10, and the breast bra 10 includes a fitting part 111 and a negative pressure part 112 provided along the breast suction channel 11;

[0044] The breast pumping channel 11 is equipped with a biomimetic structure of an infant's mouth for contacting the nipple of a breastfeeding woman. The biomimetic structure of the infant's mouth includes:

[0045] A protrusion 20 is disposed within the negative pressure part 112 and located on one side of the breast suction channel 11;

[0046] The abutment 30 is disposed within the negative pressure part 112 and located on the other side of the breast suction channel 11, and the abutment 30 and the protrusion 20 are arranged facing each other at intervals.

[0047] The breast pump assembly 100 of this invention features a breast pumping channel 11 within a breast shield 10. This channel 11 is divided into a fitting portion 111 and a negative pressure portion 112. Within the breast pumping channel 11, there are protrusions 20 and abutments 30. The protrusions 20 are located on the negative pressure portion 112 near the fitting portion 111. During breast pumping, the protrusions 20 mimic the action of an infant's tongue, lifting and supporting the nipple. The abutments 30 are located in the negative pressure portion 112, spaced apart from the protrusions 20. The abutments 30 mimic the soft palate of an infant. When the breast is within the breast pumping channel 11, the abutments 30 simulate the action of an infant latching on, stimulating the nipple. When using the breast pump assembly 100, the protrusions 20 simulate the infant's tongue, providing support and pressure to the nipple, while the abutments 30 contact the nipple, stimulating milk let-down and improving lactation efficiency.

[0048] Understandably, the breast pump assembly 100 includes a breast shield 10, which has a fitting part 111 and a negative pressure part 112. A protrusion 20 is provided below the negative pressure part 112 in the breast pump channel 11. The protrusion 20 extends toward the abutment 30, which changes the internal structure of the breast pump channel 11. When the breast is located in the breast pump channel 11, the breast can be supported by the protrusion 20, thus mimicking the support of an infant's mouth for the breast.

[0049] Understandably, the abutment 30 is disposed on the upper side wall of the negative pressure part 112 within the breast pumping channel 11, and the abutment 30 is spaced apart from the protrusion 20, that is, the abutment 30 is disposed at one end of the negative pressure part 112, and the protrusion 20 is disposed at the other end (the protrusion 20 can mimic the baby's tongue to support the nipple and apply a certain pressure to the nipple). Specifically, the abutment 30 is disposed on the side of the negative pressure part 112 away from the contact part 111, so that during breast pumping, the abutment can contact the nipple. The positions of the abutment 30 within the milk suction channel 11 are adapted to allow it to contact the nipple and stimulate it (thus, the abutment 30 is equivalent to the baby's palate, achieving the purpose of stimulating the nipple). The protrusion 20 and the abutment 30 are provided within the milk suction channel 11, and the protrusion 20 and the abutment 30 cooperate with each other. This allows the milk suction assembly 100 to mimic the movements of a baby suckling, thereby stimulating milk let-down and the nipple, and ultimately improving lactation efficiency.

[0050] Preferably, the abutment 30 is positioned at its contact point with the nipple and is located approximately 13 mm from the areola.

[0051] Please see Figure 2 In some embodiments, the abutment 30 is tilted from the end near the fitting portion 111 to the end away from the fitting portion 111.

[0052] Understandably, the abutment 30 is tilted from the end near the contact portion 111 to the end away from the contact portion 111. This reduces the distance between the abutment 30 and the nipple during breastfeeding, allowing the breast pump assembly 100 to make easier contact with the nipple during breastfeeding, thereby stimulating the nipple.

[0053] Please refer to 1 or Figure 3 In some embodiments, the diameter of the breast bra 10 gradually increases from the portion near the fitting portion 111 to the portion away from the fitting portion 111.

[0054] Understandably, the diameter of the breast pad 10 increases from the part closer to the fitting part 111 to the part farther away from the fitting part 111, that is, one end of the breast pad 10 is larger than the other end. This makes it easier for the breast pump 200 to contact the breast and also makes the breast pump assembly 100 more in line with the structure of the baby's mouth.

[0055] Please see Figure 2 In some embodiments, the milk suction channel at the negative pressure section 112 has a curved arc.

[0056] It is understandable that the breast pad 10 is designed with a curve. The curve in the breast pad 10 is generated by acquiring relevant data of the baby's mouth and generating a curve. The breast pad 10 is generated by scanning the curve so that the breast pad 10 can better mimic the baby's mouth. This also makes the breast pad 10 more ergonomic and will not cause discomfort due to the breast pumping component 100 during breast pumping, thus affecting the breast pumping experience.

[0057] In some embodiments, the protrusion 20 is made of soft rubber.

[0058] Understandably, the bra 10 is made of soft rubber or silicone, which makes it easy for the bra 10 to deform and fit the breast.

[0059] Understandably, the breast pumping channel 11 is a two-injection molded structural component. Its main feature is that the channel is scanned along an arc, which can imitate the internal structure of an infant's mouth. The first injection molded part of the breast pumping channel is hard plastic, and the second injection molded part is soft plastic. The soft plastic has a smooth surface, low hardness, is skin-friendly, and is food-grade.

[0060] Optionally, the aforementioned soft adhesive can be any one of TPE (thermoplastic elastomer), TPU (thermoplastic polyurethane), or PVC (polyvinyl chloride).

[0061] Please see Figure 2 In some embodiments, the protrusion 20 is disposed near the junction of the fitting portion 111 and the negative pressure portion 112.

[0062] Understandably, when an infant is breastfeeding, the breast is first pushed up by the infant's tongue when it enters the infant's mouth, and then the infant sucks to complete the feeding. Therefore, the protrusion 20 is positioned near the junction of the fitting part 111 and the negative pressure part 112. This allows the protrusion 20 to support the nipple when the breast enters the negative pressure part 112, which is more in line with the infant's sucking action, providing a certain amount of support and pressure to the nipple, thereby improving the user experience of the breast pump assembly 100.

[0063] Please see Figure 6 , Figure 8 and Figure 9 The present invention also provides a breast pump 200, comprising: a main body, and the aforementioned breast pumping component 100.

[0064] The breast pump component 100 in this invention is used in the breast pump 200. Therefore, the breast pump component 100 in the breast pump 200 can also mimic the baby's mouth and achieve the purpose of stimulating milk let-down and improving lactation efficiency.

[0065] Please see Figure 5 In some embodiments, the body includes: a housing 210;

[0066] The breast pump assembly 100 is detachably disposed within the housing 210. The shape of the housing 210 is adapted to the shape of the breast pump assembly 100, and the size of the housing 210 is larger than the size of the breast pump assembly 100.

[0067] Understandably, the main body includes a housing 210, within which the aforementioned breast pump assembly 100 is installed. To ensure a better fit between the housing 210 and the breast pump assembly 100, the housing 210 is shaped to conform to the breast pump assembly 100. This allows the breast pump assembly 100 to conform to the inner wall of the housing 210 when deformed, thus limiting the deformation of the breast pump assembly 100 and preventing damage due to excessive deformation. Furthermore, to ensure a comfortable breast pumping space even after deformation, the housing 210 is shaped to conform to the breast pump assembly 100, thereby improving the user experience of the breast pump 200.

[0068] Understandably, in order to better install the breast pump assembly 100 into the housing 210, the diameter of the housing 210 is set to be larger than the diameter of the breast pump assembly 100, so that the breast pump assembly 100 can be installed into the housing 210, and at the same time, the interior of the housing 210 can accommodate the deformation of the breast pump assembly 100.

[0069] Please see Figures 4 to 7 In some embodiments, a limiting part 211 is provided on the outer periphery of the housing 210, and a flange structure 14 is provided on the side of the breast bra 10 near the fitting part 111; a snap-fit ​​part 15 is provided on the side of the flange structure 14 away from the negative pressure part 112, and the snap-fit ​​part 15 cooperates with the limiting part 211 to make the breast bra 10 detachably connected to the housing 210.

[0070] Understandably, a limiting part 211 is provided on the outer periphery of the housing 210, and a flange structure 14 is provided on the side of the bra 10 near the fitting part 111. The flange structure 14 is provided around the outer periphery of one side of the housing 210, and a snap-fit ​​part 15 is provided on the side of the flange structure 14 away from the negative pressure part 112, i.e. Figure 4 The left side shown has a snap-fit ​​part 15. The flange structure 14 can be snapped into the limiting part 211 to connect the breast pump component 100 to the housing 210. During installation, since the breast pad 10 is made of soft rubber, its outer edge can be deformed and stretched. Through deformation and stretching, the flange structure 14 is snapped into the limiting part 211, so that the limiting part 211 and the flange structure 14 cooperate. Furthermore, since the direction of negative pressure suction is the same as the direction of deformation of the flange structure 14, the connection stability between the breast pad 10 and the housing 210 can be improved, and a tight connection can be achieved. This makes it easy to replace the breast pump component 100, and the breast pump component 100 can be disassembled and cleaned separately after each use of the breast pump 200, which facilitates the cleaning of the breast pump component 100 and improves the user experience.

[0071] Please see Figure 3 and Figure 7 In some embodiments, the breast pad 10 has an opening 12 on the side near the fitting part 111 and a milk discharge port 13 on the side away from the fitting part 111, and the diameter of the opening 12 is smaller than the diameter of the milk discharge port 13.

[0072] Understandably, the diameter of the opening 12 is smaller than the diameter of the milk outlet 13. This allows the breast pump 200 to more easily generate negative pressure in the negative pressure section 112 during milk expression, thereby improving milk expression efficiency. The breast shield 10 has an opening 12 on the side near the fitting part 111, and a milk outlet 13 on the side away from the fitting part 111; that is, an opening 12 is located on one side of the breast shield 10, and a milk outlet 13 is located on the other side, making both sides of the breast shield 10 connected. The nipple enters the milk expression assembly 100 through the opening 12, while the milk is discharged through the milk outlet 13, facilitating milk collection.

[0073] Please see Figure 5 and Figure 7 In some embodiments, the breast pump 200 further includes a milk storage chamber 220;

[0074] The housing 210 has a flow channel 212. One end of the flow channel 212 is connected to the milk outlet 13, and the other end of the flow channel 212 is connected to the milk storage chamber 220. Milk flows into the milk storage chamber 220 through the flow channel 212.

[0075] Understandably, the milk storage chamber 220 is located inside the housing 210, and one end of the guide channel 212 is connected to the milk outlet 13, while the other end of the guide channel 212 is connected to the milk storage chamber 220. During the milk pumping process, the milk from the milk pumping assembly 100 enters the guide channel 212 through the milk outlet 13. Specifically, during milk pumping, the side wall of the bra 10 deforms under the influence of negative pressure and squeezes the breast. At this time, the side wall of the negative pressure part 112 of the bra 10 becomes a shape that is smaller in the middle and larger on both sides. This allows the milk to flow along the side wall of the milk pumping channel 11 into the guide channel 212, so as to pump the milk into the milk storage chamber 220.

[0076] Understandably, the milk storage chamber 220 is used to store breast milk, and it can be a container that can store breast milk, such as a baby bottle; the milk storage chamber 220 can be detachably installed on the housing 210, which makes it convenient to store breast milk.

[0077] Please see Figure 5 In some embodiments, it also includes: a negative pressure pump 230;

[0078] The negative pressure pump 230 is disposed inside the housing 210 and is connected to the milk suction channel 11 to generate negative pressure in the milk suction channel 11.

[0079] Understandably, the negative pressure pump 230 is installed inside the housing 210. An opening 12 can be provided on the breast pad 10. By connecting the negative pressure pump 230 to the opening 12, the negative pressure generated by the negative pressure pump 230 can act on the milk suction channel 11, thereby generating negative pressure in the milk suction channel 11. This causes the side wall of the breast pad 10 to deform and fit against the breast, and allows the nipple to contact the abutment 30, thereby stimulating the nipple and improving lactation efficiency.

[0080] Understandably, in order to further improve lactation efficiency, the frequency at which the negative pressure pump 230 generates negative pressure is set to the same frequency as when the baby is sucking. For example, the interval between each generation of negative pressure is set to 1 second. This can better simulate the baby's response when sucking, thereby further improving lactation efficiency.
