[0003] Embodiments of the present application relate to the technical field of mother and baby appliances, in particular to a breast pump. BACKGROUND

[0004] 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 play an important role in helping mothers to extract milk, but there are still some deficiencies in actual use.

[0005] 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 pumping efficiency and even cause discomfort. Especially when the breast fullness is high, this design defect will be more obviously exposed.

[0030] In the present embodiment, the breast pump can include a milk bowl assembly 20 and a milk suction conduit 40.

[0031] The milk bowl assembly 20 is formed with a milk storage space 21. The milk storage space 21 is used to store milk.

[0032] 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. The milk in the milk guiding passage 41 flows to the milk storage space 21 under the action of negative pressure.

[0033] 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.

[0034] 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.

[0035] In an embodiment, the milk suction conduit 40 extends downwardly and obliquely. When the breast pump is worn on the user in a standing state, the milk suction conduit 40 extends downwardly and obliquely away from the human body. When the wearing surface is substantially along a vertical plane, the milk suction conduit 40 extends downwardly and obliquely away from the human body.

[0036] In an embodiment, the milk suction conduit 40 is connected to the milk bowl assembly 20 and extends into the milk storage space 21.

[0039] The milk suction device comprises a milk bowl assembly, a milk storage space is formed in the milk bowl assembly, a milk suction pipeline is connected to the milk bowl assembly, a milk guiding channel is formed in the milk suction pipeline, and milk in the milk guiding channel flows to the milk storage space under the action of negative pressure. The milk suction pipeline extends in a direction that is not perpendicular to the areola of the human body when the milk suction device is worn on the human body. The milk suction pipeline is arranged on the milk bowl assembly and extends in a direction that is not perpendicular to the areola of the human body, which can improve the flowability of milk in the milk suction pipeline, thereby improving the efficiency of milk suction, reducing power consumption, and improving the compactness of the structure of the milk suction device. In particular, when the user lies down to suck milk, the milk will not flow back.

In other embodiments, the purification unit 30 can be arranged on only the longitudinal portion or only the transverse portion, which is not limited in the embodiments of the present application. The number of the purification unit 30 can be one, two or more. In the above manner, the purification unit 30 is arranged on the transverse portion 11 and the longitudinal portion 12 of the main machine 10 respectively or individually to realize multi-directional and multi-angle disinfection of the milk bowl assembly 20, thereby further improving the hygiene level.
