[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 9 In the embodiment, the breast pump can include a breast pumping conduit 10 and a milk storage container 20.
[0033] The breast pumping conduit 10 is formed with a milk guiding passage 11 for receiving milk from the breast, and the breast pumping conduit 10 is provided with a milk outlet 12 through which negative pressure is transmitted to the milk guiding passage 11.
[0034] The milk storage container 20 is formed with a milk storage space 21, and the milk in the milk guiding passage 11 flows out of the milk guiding passage 11 through the milk outlet 12 and flows to the milk storage space 21. Here, the flow direction refers to direct flow into the milk storage space 21 or indirect flow (for example, through a negative pressure chamber before flowing into the milk storage space 21), which is not limited in the present application.
[0035] In the above manner, the transmission of negative pressure and the flow of milk are both through the milk outlet 12, and the milk flows along the direction of the air flow formed by the negative pressure, so that the milk does not remain in the milk guiding passage 11, and the efficiency of breast pumping is higher.
[0036] In an embodiment, the milk storage container 20 is a milk bowl assembly 20, and the breast pumping conduit 10 is connected to the milk bowl assembly 20. In some embodiments, the milk storage container can also be a milk bottle, and when a milk bottle is used, the bottle opening of the milk bottle can be directly or indirectly connected to the milk outlet 12. In some embodiments, the breast pumping conduit 10 can be integrated with the milk bowl assembly 20, and in other embodiments, the breast pumping conduit 10 can be detachably connected to the milk bowl assembly 20, which is not limited in the present application. The breast pumping conduit 10 can extend into the milk storage space 21.
[0037] In one embodiment, the milk bowl assembly 20 includes a bowl body 22 and a cover plate 23, which together form a milk storage space 21. A milk suction tube 10 is connected to the cover plate 23. In some embodiments, the milk suction tube 10 may be detachably connected to the cover plate 23 or may be integrally connected to it; this application does not limit this aspect.
[0038] In one embodiment, the breast pump further includes a diaphragm support 30, within which a negative pressure chamber 31 is formed. The negative pressure chamber 31 communicates with the milk guide channel 11 via a milk outlet 12. The diaphragm support 40 may be located below the milk suction tube 10, and may extend parallel to the milk suction tube 10. The diaphragm support 40 may extend into the milk storage space 21.
[0039] In one embodiment, the diaphragm support 30 is provided with a milk outlet 32. The milk in the milk guiding channel 11 flows out of the milk guiding channel 11 through the milk outlet 12, then flows through the negative pressure chamber 31 and then through the milk outlet 32 into the milk storage space 21.
[0040] like Figure 5 As shown, in another embodiment, the breast pump includes a breast shield 23a, and a breast tube 10a connected to the breast shield 23a. A milk-guiding channel 11a is formed within the breast tube 10a, which receives milk from the breast. A milk outlet 12a is provided on the breast tube 10a, through which negative pressure is transmitted to the milk-guiding channel 11a. The breast pump may also include a diaphragm support 30a, within which a negative pressure chamber 31a is formed, communicating with the milk-guiding channel 11a via the milk outlet 12a. The diaphragm support 30a is provided with a milk flow outlet 32a, through which milk in the milk-guiding channel 11a flows out of the milk-guiding channel 11a via the milk outlet 12a, then flows through the negative pressure chamber 31a, and finally through the milk flow outlet 32a into the milk storage space.
[0041] In one embodiment, the breast pump further includes a main unit 40, which provides negative pressure. The main unit 40 may include a housing and components such as a negative pressure pump, a solenoid valve, a battery, and a circuit board located within the housing. The main unit 40 may be an integrated breast pump with the feeding bowl assembly 20 or a separate breast pump connected to the feeding bowl assembly 20 via tubing. It should be understood that the provision of negative pressure is not limited to an electric negative pressure pump; a manual negative pressure mechanism can also be used. This application embodiment does not limit this. In some embodiments, the breast pump may not include a mechanism for providing negative pressure, but instead provides negative pressure through externally supplied power.
[0042] In one embodiment, the breast pump further includes a main unit 40, which includes a negative pressure interface 44 that may be connected to a negative pressure pump.

[0043] In one embodiment, the negative pressure chamber 31 is at least partially lower than the milk channel 11 when the breast pump is worn. In some embodiments, the negative pressure chamber 31 is completely below the milk channel 11. "Wearing" here can refer to wearing the breast pump in a normal upright position, i.e., with the wearing surface substantially vertical.
[0044] like Figure 6 As shown, in some embodiments, the negative pressure chamber 31b may only be a portion located below the milk channel 11b. The milk suction tube 10b is connected to the cover plate 23b, and the milk channel 11b is formed within the milk suction tube 10b. The milk channel 11b is used to receive milk from the breast; the milk suction tube 10b is provided with a milk outlet 12b, located at the end of the milk suction tube 10b, through which negative pressure is transmitted to the milk channel 11b. The breast pump may also include a diaphragm support 30b, within which a negative pressure chamber 31b is formed, communicating with the milk channel 11b via the milk outlet 12b. The diaphragm support 30b is provided with a milk outlet 32b, through which milk in the milk channel 11b flows out of the milk channel 11b via the milk outlet 12b, then flows through the negative pressure chamber 31b and then through the milk outlet 32b into the milk storage space.
[0045] By employing the above method, the negative pressure chamber is at least partially located below the milk channel, which can improve the efficiency of milk expression and prevent milk from getting trapped.
[0046] In one embodiment, the breast pump also includes a diaphragm 50 disposed within the negative pressure chamber 31, the diaphragm 50 being driven at least partially below the milk channel 11 when the breast pump is worn.

The negative pressure cavity 31c is in communication with the milk channel 11c through the milk outlet 12c. The diaphragm holder 30c is provided with a milk outlet 32c. The milk in the milk channel 11c flows out of the milk channel 11c through the milk outlet 12c, and then flows through the negative pressure cavity 31c and the milk outlet 32c into the milk storage space.
[0050] In an embodiment, the milk outlet 12 is located between the end of the milk duct 10 and the cover plate 23. The milk in the milk channel 11 flows out of the milk duct 10 through the milk outlet 12 under the action of negative pressure. The milk duct 10 includes a distal end away from the cover plate 23, and the milk outlet 12 is located between the cover plate 23 and the distal end. In this way, the milk outlet 12 is located between the end of the milk duct 10 and the cover plate 23, which can make the overall structure of the breast pump more compact, improve the efficiency of milk extraction, and avoid milk storage.
[0051] As shown in Figure 3 , Figure 4 and Figure 8 In an embodiment, the distal end of the milk duct 10 is a closed end.
