[0145] Please refer to Figures 4-6, Figure 4 is a schematic diagram of the structure of the breast pump of the embodiment. Figure 5 is a schematic diagram of the first split structure of the breast pump of the embodiment. Figure 6 is a schematic diagram of the second split structure of the breast pump of the embodiment.

[0146] In the embodiment, the breast pump comprises a host 20a and a milk bowl assembly 10a.

[0147] The host 20a comprises a transverse portion 21a and a longitudinal portion 22a connected to the transverse portion 21a by bending. The angle between the transverse portion 21a and the longitudinal portion 22a is substantially 90a degrees, but the embodiment is not limited in this regard, as long as they extend by bending relative to each other.

[0148] The first side 70a of the milk bowl assembly 10a is in contact with the longitudinal portion 22a of the host 20a, and the second side 80a of the milk bowl assembly 10a is in contact with the transverse portion 21a of the host 20a. The first side 70a and the second side 80a are two adjacent sides of the milk bowl assembly 20a.

[0149] In the above manner, the host 20a is in the shape of L, forming an L-shaped step, and the milk bowl assembly 10a is accommodated in the L-shaped step of the host 20a. This layout facilitates the miniaturization and thinning of the breast pump as a whole, and facilitates the layout of the space inside the host. The components of the breast pump can be closely assembled together, the layout is reasonable, the volume of the breast pump as a whole is effectively reduced, thereby facilitating carrying and use, and improving the user experience.

[0150] In the present embodiment, the upper half of the longitudinal portion 22a of the main body 20a has a greater thickness than the lower half of the longitudinal portion 22a of the main body 20a. In some embodiments, the thickness of the upper half can refer to the average thickness of the upper half at various positions in the height direction, and the thickness of the lower half can refer to the average thickness of the lower half at various positions in the height direction.

[0151] In this way, on the one hand, it is conducive to the layout of the internal elements of the main body 20a. The sizes of the internal elements of the main body are often inconsistent, such as negative pressure pumps, solenoid valves, batteries, circuit boards, etc. Therefore, larger elements can be arranged on the upper side, and smaller elements can be arranged on the lower side. On the other hand, the thickness of the lower half of the milk bowl assembly can be made thicker without changing the overall thickness of the breast pump, thereby increasing the volume of the lower half of the milk bowl assembly, thereby reducing the probability of milk overflowing the one-way valve or milk outlet inside the milk bowl assembly, and improving the efficiency of breast pumping and reducing the risk of backflow and energy consumption. On the other hand, the milk bowl assembly and the main body can be staggered with each other, which is more convenient for the up-down and left-right limiting design between the milk bowl assembly and the main body.

[0152] In one embodiment, the thickness of the longitudinal portion 22a of the main body 20a gradually decreases from top to bottom.

[0155] In one embodiment, the thickness of the transverse portion 21a of the main body 20a gradually decreases along the direction towards the connection between the transverse portion 21a and the longitudinal portion 22a.

[0156] In an embodiment, the surface of the lateral portion 21a of the host 20a that is in contact with the milk bowl assembly 10a is non-planar. For example, the upper surface of the lateral portion 21a of the host 20a is convex towards the second side 80a of the milk bowl assembly 10a, and the upper surface of the lateral portion 21a of the host 20a is curved, which on one hand increases the contact area between the host 20a and the milk bowl assembly 10a, and facilitates heat dissipation from the milk in the milk bowl assembly 10a to the host 20a. The curved surface is not limited to a smooth transition curved surface, and can also be a non-smooth transition curved surface, such as an angularly bent surface, a jagged surface, a wavy surface, etc. The shape of the second side 80a of the milk bowl assembly 10a substantially matches the shape of the upper surface of the lateral portion 21a. On the other hand, the non-planar design also facilitates the limiting design between the host 20a and the milk bowl assembly 10a in the lateral direction, and facilitates positioning during installation.

[0157] In an embodiment, the longitudinal portion 22a of the host 20a is provided with a through hole in the thickness direction; the breast pump further comprises a breast shield 30a, the breast shield 30a has a narrow end and a wide end, the narrow end of the breast shield 30a is arranged in the through hole, and the host 20a is at least partially located between the wide end of the breast shield 30a and the milk bowl assembly 10a.

[0159] In an embodiment, the breast pumping pipeline 40a is located above the diaphragm holder 50a.

[0160] In an embodiment, the breast pump further comprises a diaphragm 60a, the diaphragm 60a is arranged in the negative pressure cavity, the diaphragm 60a divides the internal space of the diaphragm holder 50a into a first sub-space and a second sub-space, the first sub-space is in communication with the negative pressure interface 23a of the host 20a, the second sub-space is in communication with the internal space of the breast pumping pipeline 40a, and the diaphragm 60a is deformed in the internal space of the diaphragm holder under the driving of the negative pressure provided by the host to transmit the negative pressure.

[0161] The milk suction device comprises a main machine, the main machine comprises a transverse part and a longitudinal part which is connected to the transverse part in a bending manner, the thickness of the upper half of the longitudinal part of the main machine is greater than the thickness of the lower half of the longitudinal part of the main machine, a milk bowl assembly, the first side of the milk bowl assembly is in contact with the longitudinal part of the main machine, the second side of the milk bowl assembly is in contact with the transverse part of the main machine, and the first side and the second side are two adjacent sides of the milk bowl assembly.
