[0031] Currently, the components of a breast pump assembly are usually connected in a detachable manner so that the components can be disassembled and cleaned after breastfeeding is completed. However, this results in an excessive number of components in the breast pump assembly, making disassembly cumbersome and easy to lose.

[0032] In view of this, the present application provides a novel milk extraction assembly and a breast pump, which reduce the number of parts while ensuring that each part can be cleaned.

[0033] As shown in Figures 1 to 3, the breast pump assembly 100 provided in an embodiment of the present application includes a shield 10, a shell 20, and a sealing cover 30. The shield 10 is provided with a nipple passage 121 and a milk outlet 122. The shell 20 is disposed on one side of the shield 10. The sealing cover 30, the shield 10, and the shell 20 together form a milk storage chamber (not shown). The nipple passage 121 extends into the milk storage chamber, and the milk outlet 122 connects the nipple passage 121 and the milk storage chamber. The nipple passage 121 is used to accommodate the nipple. After milk is extracted from the nipple, it passes through the milk outlet 122 and enters the milk storage chamber for temporary storage.

[0034] As one embodiment, as shown in Figures 1 and 3 , the milking assembly 100 further includes a one-way valve 40. The one-way valve 40 is fixedly connected to the sealing cap 30 and located within the milk storage chamber, and is used to open or close the milk flow port 122. When the one-way valve 40 opens the milk flow port 122, the nipple passage 121 and the milk storage chamber are connected via the milk flow port 122, allowing milk in the nipple passage 121 to flow into the milk storage chamber through the milk flow port 122. When the one-way valve 40 closes the milk flow port 122, the nipple passage 121 and the milk storage chamber are isolated, preventing milk from flowing from the nipple passage 121 to the milk storage chamber. The one-way valve 40 restricts milk flow from the nipple passage 121 to the milk storage chamber. By fixedly connecting the one-way valve 40 to the sealing cap 30, compared to a detachable connection, the number of parts in the milking assembly 100 is reduced, simplifying assembly and disassembly of the milking assembly 100 and preventing loss of the one-way valve 40.

[0035] In one embodiment, the one-way valve 40 and the sealing cover 30 are integrally molded. This reduces the number of assembly steps required during production and prevents the two from separating after a period of use due to loose assembly. Preferably, the one-way valve 40 and the sealing cover 30 are integrally molded. Of course, in specific applications, as an alternative embodiment, the one-way valve 40 and the sealing cover 30 can be manufactured separately and then fixedly connected.

[0036] As shown in Figures 1 and 3 , the breast pump assembly 100 further includes a diaphragm support 50 and a diaphragm 60. The diaphragm support 50 defines a receiving cavity 51 that communicates with the nipple passage 121. The diaphragm 60 is disposed between the diaphragm support 50 and the sealing cap 30 and accommodated within the receiving cavity 51. The sealing cap 30 seals the diaphragm 60. When installed, the diaphragm 60 seals the diaphragm support 50 and forms a sealed space with the diaphragm support 50 that communicates with the nipple passage 121. The diaphragm 60 deforms, causing changes in air pressure within the nipple passage 121, thereby promoting milk secretion.

[0037] As one embodiment, referring to Figures 1 and 3 , the shield 10 includes a flange 11 and a tee 12. The flange 11, the sealing cover 30, and the housing 20 enclose a milk storage chamber. The tee 12 is connected to the flange 11 and extends toward the milk storage chamber. The nipple channel 121 and the milk outlet 122 are both formed in the tee 12. This allows the milk outlet 122 to communicate with the milk storage chamber, allowing milk in the nipple channel 121 to flow into the milk storage chamber through the milk outlet 122.

[0038] As an embodiment, the flange 11 and the tee 12 are integrally formed, thus reducing the number of parts of the milking assembly 100 while maintaining ease of cleaning of the flange 11 and the tee 12 .

[0039] As one embodiment, referring to Figures 3 and 4 , the sealing cap 30 includes a cap body 31 and a connector 32 connected to the cap body 31. The cap body 31 seals the diaphragm 60 and, together with the housing 20 and the protective cover 10, forms a milk storage chamber. The connector 32 extends into the milk storage chamber and is fixedly connected to the one-way valve 40. Specifically, the cap body 31, the housing 20, and the flange 11 form the milk storage chamber. The connector 32 is connected to the inner side of the cap body 31 and includes a first connecting portion 321 and a second connecting portion 322. The first connecting portion 321 is connected between the cap body 31 and the second connecting portion 322, and the one-way valve 40 is fixedly connected to the second connecting portion 322.

[0040] As an embodiment, the cover body 31 and the connecting member 32 are integrally formed. In this way, the number of parts of the milking assembly 100 is reduced while the cleaning of the sealing cover 30 is not affected.

[0041] As one embodiment, as shown in Figures 3 and 4 , the connector 32 is provided with a mounting groove 323, a portion of the groove wall of which is positioned directly opposite the milk outlet 122. The one-way valve 40 is mounted within the mounting groove 323 and extends to the milk outlet 122, shielding the milk outlet 122. Preferably, the plane of the mounting groove 323 intersects the plane of the milk outlet 122, and the portion of the groove wall of the mounting groove 323 away from the milk outlet 122 directly faces the milk outlet 122. This allows the one-way valve 40 to be pressed against the milk outlet 122, improving the sealing performance of the one-way valve 40 when isolating the milk outlet 122 from the milk storage chamber. Specifically, the mounting groove 323 is formed in the second connecting portion 322.

[0042] In one embodiment, the one-way valve 40 is made of a soft rubber material, while the sealing cap 30 is made of a hard rubber material. In other words, the second connecting portion 322 of the connector 32 is made of a hard rubber material. When the hard rubber second connecting portion 322 presses against the soft rubber one-way valve 40, the force exerted on the one-way valve 40 is greatly increased, thereby firmly pressing the one-way valve 40 against the milk outlet 122.

[0043] As shown in Figures 3 and 4 , a one-way valve 40 includes a mounting portion 41 and a separating portion 42 connected to the mounting portion 41. The mounting portion 41 is mounted within the mounting slot 323 , and the separating portion 42 is positioned adjacent to the milk outlet 122 to shield the milk outlet 122 . Preferably, the separating portion 42 is a sheet-like structure. Compared to existing duckbill valve structures, this design offers a simpler structure and is easier to manufacture.

[0044] In one embodiment, the connector 32 is detachably connected to the outside of the nipple passage 121. In other words, the connector 32 is detachably connected to the tee 12. On one hand, the connector 32, attached to the outside of the nipple passage 121, supports the cover body 31 and enhances the secure installation of the sealing cover 30. On the other hand, the detachable connection of the connector 32 allows the sealing cover 30 to be removed separately for cleaning. Specifically, the first connector 321 is detachably connected to the tee 12.

[0045] As one embodiment, as shown in Figures 4 and 5, one of the first connecting portion 321 and the tee member 12 is provided with a slot 71, and the other is provided with a ridge 72 that is snap-connected to the slot 71. The first connecting portion 321 and the tee member 12 are detachably connected by the snap-connection between the slot 71 and the ridge 72. Preferably, at least the first connecting portion 321 has a certain degree of elasticity. When the slot 71 and the ridge 72 are snap-connected, the first connecting portion 321 undergoes a certain degree of deformation, so that the slot 71 and the ridge 72 can be easily snapped together.

[0046] For example, in this embodiment, the first connecting portion 321 is provided with a slot 71 , and the tee piece 12 is provided with a protrusion 72 .

[0047] As an embodiment, when the milk pump assembly 100 is placed on the breast, the cover body 31 is located above the housing 20, and the width above the cover body 31 is greater than the width below the cover body 31. This helps to position the cover body 31.

[0048] In one embodiment, the area of ​​the cover body 31 is larger than the area of ​​the opening of the accommodating chamber 51. Specifically, the diaphragm 60 is mounted at the opening of the accommodating chamber 51 and extends into the accommodating chamber 51. The larger area of ​​the cover body 31 than the opening of the accommodating chamber 51 not only seals the diaphragm 60 but also forms a milk storage chamber together with the flange 11 and the housing 20.

[0049] As one embodiment, referring to Figures 3 and 4 , the cover body 31 is provided with a groove 311 and a negative pressure port 312 directly opposite the opening of the accommodating chamber 51. Preferably, the groove 311 is an annular groove surrounding the negative pressure port 312. In specific applications, the breast pump main unit can generate negative pressure at the negative pressure port 312, causing the diaphragm 60 to deform, thereby causing a change in air pressure within the nipple passage 121. If the diaphragm 60 unexpectedly falls off, milk may enter the space between the sealing cover 30 and the diaphragm 60. The groove 311 can contain the milk and prevent it from entering the main unit through the negative pressure port 312.

[0050] In one embodiment, the sealing cover 30 is connected between the flange 11 and the housing 20; that is, the cover body 31 is connected between the flange 11 and the housing 20. When the cover body 31, the flange 11, and the housing 20 are assembled to enclose the milk storage chamber, one end of the cover body 31 is connected to the flange 11, and the other end of the cover body 31 is connected to the housing 20. When the housing 20 and the flange 11 are separated, one end of the cover body 31 is free (i.e., not connected to other components), making it easy to remove the cover body 31.

[0051] In one embodiment, the milk outlet 122 is formed at the end of the tee 12 away from the flange 11. Specifically, the outer shell 20 and the cover body 31 are both curved and located on one side of the flange 11. The tee 12 extends toward the milk storage chamber, that is, toward the outer shell 20 and the cover body 31. Positioning the milk outlet 122 at the end of the tee 12 away from the flange 11, that is, at the end of the tee 12 close to the outer shell 20 and the cover body 31, shortens the distance between the milk outlet 122 and the cover body 31, facilitating the design of the connector 32. Preferably, when the milk pump assembly 100 is placed on the breast, the milk outlet 122 extends gradually away from the flange 11 from top to bottom. That is, the milk outlet 122 is tilted, taking advantage of the tight fit of the one-way valve 40.

[0052] In one embodiment, the diaphragm support 50 is connected to the flange 11 and arranged side by side with the tee 12. Preferably, the opening of the accommodating chamber 51 is located at the end of the diaphragm support 50 away from the flange 11. Combined with the milk outlet 122 being located at the end of the tee 12 away from the flange 11, this arrangement utilizes the design of the sealing cover 30, making its structure more rational and simple.

[0053] As an embodiment, the diaphragm support 50 and the shield 10 are integrally formed. In this way, the number of parts of the milk pump assembly 100 is reduced while the cleaning of the sealing cover 30 is not affected.

[0054] Furthermore, the embodiment of the present application also provides a breast pump, comprising the above-mentioned milk suction assembly 100. The above-mentioned milk suction assembly 100 can simplify the assembly steps of the breast pump.

[0055] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made based on the contents of the present application specification and drawings, or direct / indirect application in other related technical fields, are included in the patent protection scope of the present application.
