[0026] In this embodiment, the breast pump includes: a milk bowl assembly 10 , a main unit 20 , a breast shield 30 , and a milk suction duct 40 .

[0027] A milk storage space is formed in the milk bowl assembly 10 .

[0028] The main body 20 is formed with a through hole T extending through the main body 20 in the thickness direction.

[0029] The breast shield 30 has a narrow end and a wide end. The narrow end of the breast shield 30 is inserted through the through hole T. The main unit 20 is at least partially located between the wide end of the breast shield 30 and the bowl assembly 10. The breast pump of this embodiment of the application adopts a three-piece structure, with the breast shield 30 and the bowl assembly 10 sandwiching the main unit 20. This structure facilitates the miniaturization of the breast pump. This structure forms a through hole T in the main unit 20, and the portion of the main unit 20 sandwiched between the breast shield 30 and the bowl assembly 10 is generally annular.

[0030] The milk duct 40 communicates with the interior space of the breast shield 30. When the milk storage space is empty, the center of gravity of the breast pump is located within the through hole T of the main unit 20 or within the milk duct 40. The main unit 20 includes a housing and a first suction power assembly 201 and a second suction power assembly 202 located within the housing. The first suction power assembly 201 and the second suction power assembly 202 are located on opposite sides of the through hole T. In this embodiment, by using two sets of suction power assemblies, the size of a single suction power assembly can be made smaller while maintaining sufficient suction force. These assemblies can be located on opposite sides of the through hole T, facilitating the positioning of the center of gravity. This also makes the internal layout of the main unit 20 more compact, facilitating a miniaturized design of the main unit 20 and, ultimately, the entire breast pump.

[0031] In one embodiment, the main unit 20 further includes a first battery 203 and a second battery 204 located within the housing, with the first battery 203 and the second battery 204 located on opposite sides of the through-hole. In some embodiments, the positions of the suction power assembly and the batteries can be interchanged, as long as the center of gravity is located within the through-hole T or within the milk duct 40.

[0032] In one embodiment, the first suction power assembly 201 is located on the upper left side of the through hole T, the second suction power assembly 202 is located on the upper right side of the through hole T, the first battery 203 is located on the lower left side of the through hole T, and the second battery 204 is located on the lower right side of the through hole T.

[0033] In one embodiment, the host 20 further includes a first circuit board 205 , which is located above the through hole T. The first circuit board 205 can be used for electrical connection of components such as buttons, display screens, or touch screens.

[0034] In one embodiment, the host 20 further includes a second circuit board 206 , which is located below the through hole T. The second circuit board 206 can be used for electrical connection of components such as sensors or chips.

[0036] The first negative pressure pump 2011 is an air diaphragm pump or a piezoelectric pump, and the second negative pressure pump 2021 is an air diaphragm pump or a piezoelectric pump.

[0037] The main unit 20 includes a transverse portion 21 and a longitudinal portion 22 bent and connected to the transverse portion 21. The through hole T is provided on the longitudinal portion 22. The longitudinal portion 22 is located between the wide end of the breast shield 30 and the milk bowl assembly 10. The first side surface of the milk bowl assembly 10 contacts the longitudinal portion 22 of the main unit 20, and the second side surface of the milk bowl assembly 10 contacts the transverse portion of the main unit 20. The first side surface and the second side surface are two adjacent side surfaces of the milk bowl assembly 10.

[0038] The second circuit board 206 is disposed inside the transverse portion 21 .

[0039] 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 the milk storage space, and the milk suction duct 40 is connected to the cover plate 12 .

[0040] In one embodiment, the milk bowl assembly 10 includes a bowl body 11 and a cover plate 12 , and the breast pump further includes a diaphragm bracket 50 , a negative pressure cavity is formed in the diaphragm bracket 50 , and the milk suction duct 40 and the diaphragm bracket 50 are both connected to the cover plate 12 .

[0041] In one embodiment, the milk duct 40 is located above the diaphragm support 50 .

[0042] In one embodiment, the breast pump further includes a diaphragm 60, which is used to be placed in the negative pressure chamber. The diaphragm 60 divides the internal space of the diaphragm support 50 into a first subspace and a second subspace. The first subspace is connected to the negative pressure interface of the host 20, and the second subspace is connected to the internal space of the milk suction duct 40. The diaphragm 60 can be deformed in the internal space of the diaphragm support under the drive of the negative pressure provided by the host to transmit negative pressure.

[0043] The present embodiment of the present invention provides a breast pump comprising: a bowl assembly having a milk storage space formed therein; a main unit having a through-hole extending through the main unit; a breast shield having a narrow end and a wide end, the narrow end of the breast shield being inserted through the through-hole; the main unit being at least partially located between the wide end of the breast shield and the bowl assembly; and a milk duct communicating with the interior space of the breast shield. When the milk storage space is empty, the center of gravity of the breast pump is located within the through-hole of the main unit or within the milk duct. The main unit comprises a housing and a first suction power assembly and a second suction power assembly located within the housing, the first suction power assembly and the second suction power assembly being located on opposite sides of the through-hole. This ensures that the center of gravity of the breast pump is stable when worn, making it more comfortable to wear and less likely to fall.
