[0002] In the field of mother and baby care, as an important auxiliary tool, breast pumps are widely used for women during the postpartum lactation period. By simulating the sucking action of a baby, a breast pump helps a mother suck out milk from the breast, thus facilitating storage, feeding, or maintaining normal breast secretion. However, in the design and use of existing breast pumps, there is generally a problem of air leakage, which not only affects the milk sucking efficiency of the breast pump but may also cause unnecessary pressure or damage to the mother's breast.

[0003] However, during actual use, air leakage easily occurs during the milk sucking process. Air leakage not only reduces the milk sucking efficiency of the breast pump, making the mother spend more time and energy collecting milk, but may also cause discomfort or damage to the mother's breast due to unstable negative pressure.

[0027] In this embodiment, the breast pump includes: a breast shield 30, a breast milk duct 40, and a sealing structure 31.

[0028] The breast shield 30 has a narrow end and a wide end, and the inner diameter of the breast shield 30 gradually increases from the narrow end to the wide end.

[0029] One end face of the breast milk duct 40 abuts against the end face of the narrow end of the breast shield 30, and the breast milk duct 40 is communicated with the inner space of the breast shield 30. By the way that one end face of the breast milk duct 40 abuts against the end face of the narrow end of the breast shield 30, it can avoid the docking method of inserting the narrow end of the breast shield 30 into the breast milk duct 40, so that the inner space of the breast milk duct 40 can be designed larger under the same size.

[0030] In this embodiment, the sealing structure 31 is arranged around the port of the narrow end. In some embodiments, the sealing structure can also be arranged around the port of one end of the breast milk duct 40 close to the breast shield 30.

[0031] In this embodiment, the sealing structure 31 is arranged at the port of the narrow end of the breast shield.

[0032] In this embodiment, the sealing structure 31 is in a trumpet shape and its inner diameter gradually expands along the direction close to the breast milk duct 40. By the above method, when the narrow end of the breast shield 30 is docked with the breast milk duct 40, the sealing structure 31 can better fit the end face of the breast milk duct 40 to form a better sealing effect.

[0033] In one embodiment, the sealing structure 31 is made of a soft material, and at least part of the narrow end of the breast shield 30 is made of a hard material.

[0034] In one embodiment, more than 50% of the area of the breast shield 30 is made of a soft material. For example, as Figure 3 and Figure 4 shown, the breast shield 30 includes a soft part 32 and a hard part 33. The soft part 32 is the part close to the wide end of the breast shield 30, and the hard part 33 is the part close to the narrow end. The soft part 32 contacts the user during wearing to provide a soft, comfortable and skin-friendly effect, and the hard part 33 is beneficial to the connection between the breast shield 30 and the main body 20. For example, a card slot 331 is arranged on the hard part of the breast shield 30, and a marble is arranged at the through hole on the main body 20. When the narrow end of the breast shield 30 is inserted into the through hole, the marble is stuck into the card slot 331 to realize the detachable connection between the main body 20 and the breast shield 30. Optionally, the card slot 331 is arranged in a ring shape, that is, a circle of card slots 331 is arranged on the outer wall of the narrow end, so that the breast shield 30 can be inserted into the through hole at any orientation and cooperate with the marble.

[0035] In one embodiment, the sealing structure 31 is integrally formed with the breast milk shield 30. Specifically, a one-piece injection molding process of hard and soft rubber can be adopted for forming.

[0036] In one embodiment, the breast pump further includes a milk bowl assembly 10. A milk storage space is formed in the milk bowl assembly 10. The breast milk suction pipe 40 is connected to the milk bowl assembly 10 and extends into the milk storage space.

[0037] As one embodiment, the breast pump further includes a diaphragm bracket 40 extending in the milk bowl assembly 10. The diaphragm bracket 40 is located below the breast milk suction pipe 50.

[0038] As one embodiment, the milk bowl assembly 10 includes a bowl body 11 and a cover plate 12. The bowl body 11 and the cover plate 12 enclose to form a milk storage space. The breast pump further includes a breast milk suction pipe 50 and a diaphragm bracket 40. A negative pressure chamber is formed in the diaphragm bracket 40. Both the breast milk suction pipe 50 and the diaphragm bracket 40 are connected to the cover plate 12.

[0039] In one embodiment, the breast milk suction pipe 50 and the diaphragm bracket 40 are integrally formed with the cover plate 12.

[0040] In one embodiment, the breast pump further includes a main body 20. A through hole penetrating in the thickness direction is provided on the main body 20. The narrow end of the breast milk shield 30 is inserted through the through hole. At least a part of the main body 20 is located between the wide end of the breast milk shield 30 and the milk bowl assembly 20.

[0041] In one embodiment, the main body 20 includes a horizontal part 21 and a vertical part 22 bent and connected to the horizontal part 21. The first side surface of the milk bowl assembly 10 contacts the vertical part of the main body 20. The second side surface of the milk bowl assembly 10 contacts the horizontal part 21 of the main body 20. The first side surface and the second side surface are two adjacent side surfaces of the milk bowl assembly 10.

[0042] In one embodiment, the breast milk shield 30 is detachably connected to the main body 20.

[0043] Optionally, the breast pump further includes a diaphragm 60. The diaphragm 60 is used to be placed in the negative pressure chamber. The diaphragm 60 divides the internal space of the diaphragm bracket 50 into a first sub-space and a second sub-space. The first sub-space is communicated with the negative pressure interface 23 of the main body 20. The second sub-space is communicated with the internal space of the breast milk suction pipe 40. The diaphragm 60 can be deformed in the internal space of the diaphragm bracket 50 under the negative pressure provided by the main body 20 to transmit the negative pressure.
