[0002] With the development of society and the improvement of breastfeeding awareness, breast pumps as an auxiliary breastfeeding tool are increasingly favored by new mothers. Traditional breast pump designs usually include a milk bowl assembly for collecting milk and a breast pumping pipeline. These devices have played an important role in helping mothers to extract milk, but there are still some deficiencies in actual use.

[0003] On the one hand, traditional breast pumps are often large in size and complex in structure, which not only occupies a lot of storage space, but also is not convenient to carry. This is particularly inconvenient for new mothers who need to go out frequently or do not have enough private space at work. In addition, the larger size may also affect the comfort of the user, especially in the case of long-term wear. On the other hand, the smoothness of the breast pumping process is also one of the focuses of users. Some products on the market currently have an unreasonable design of the breast pumping pipeline, which makes the milk flow not natural and smooth enough, which may lead to low efficiency of breast pumping and even cause discomfort. Especially when the breast is full, this design defect will be more obviously exposed. SUMMARY

[0028] The milk bowl assembly 20 is formed with a milk storage space 21. The milk storage space 21 is used to store milk.

[0029] The milk suction conduit 40 is connected to the milk bowl assembly 20, and the milk suction conduit 40 is formed with a milk guiding passage 41. Milk in the milk guiding passage 41 flows to the milk storage space 21 under the action of negative pressure.

[0030] The milk suction conduit 40 extends in a direction that is not perpendicular to the areola of the human body when the breast pump is worn on the human body.

[0031] In an embodiment, the milk bowl assembly 20 includes a bowl body 22 and a cover plate 23, and the bowl body 22 and the cover plate 23 jointly form the milk storage space 21. The milk suction conduit 40 extends in a direction that is not perpendicular to the cover plate 23.

[0032] In an embodiment, the milk suction conduit 40 extends downwardly and obliquely.
