[0050] Please refer to FIG. 1, the present application provides a breast pump 100, the breast pump 100 includes a milk storage assembly and a negative pressure assembly 15, the milk storage assembly is in contact with milk liquid when the breast pump 100 works; the negative pressure assembly 15 is used for directly or indirectly applying negative pressure to the milk storage assembly to cause the mother's milk to be pumped out and stored in the milk storage assembly, and the negative pressure assembly 15 is not in contact with the milk liquid.

[0051] Among them, the milk storage assembly includes a breast shield 11, a milk storage container 12 and an elastic barrier 13; the breast shield 11 is used for sealing the chest; the milk storage container 12 is in liquid communication with the breast shield 11 to collect and store the mother's milk; the elastic barrier 13 is connected or in gas communication with the negative pressure assembly 15, and can be driven to vibrate by the negative pressure assembly 15 to cause the breast shield 11 or the milk storage container 12 to form intermittent negative pressure, thereby guiding the mother's milk to flow into and store in the milk storage container 12; the elastic barrier 13 is integrally formed with one of the breast shield 11 or the milk storage container 12, the breast shield 11 and the milk storage container 12 can be divided into two independent parts, and the milk storage assembly can only be divided into two independent parts.

[0052] By the technical scheme of the present application, when the user uses the breast pump 100, the breast is attached to the breast shield 11, the negative pressure assembly 15 works to form a negative pressure in the milk storage assembly, and the milk is sucked into the milk storage container 12. Therefore, only the wall surface of the milk storage assembly is in contact with the milk during the disassembly and cleaning of the breast pump. Only two integrated components of the milk storage assembly need to be disassembled and cleaned separately, which reduces the number of parts to be cleaned, prevents loss, and is more convenient to clean. During assembly, only the two integrated components need to be assembled together, which further improves the assembly convenience of the breast pump after cleaning, and reduces the risk of poor sealing caused by improper assembly of some parts.

[0053] The specific way of integrally forming between each component is various, and injection molding, hot melting, or integrally forming through extrusion, blow molding, welding, and encapsulation can be adopted to integrally connect rigid materials and flexible materials. Different processes are selected according to actual schemes.

[0054] In some embodiments of the present application, the breast shield 11 of the breast pump 100 includes a milk outlet to ensure smooth flow of milk into the milk storage container 12.

[0055] The direct application of negative pressure by the negative pressure assembly 15 to the milk storage assembly means that no air path pipeline is arranged between the negative pressure assembly 15 and the milk storage container 12 or the nipple passage 102, and the two are directly connected and pneumatically communicated. The indirect application of negative pressure by the negative pressure assembly 15 to the milk storage assembly means that the negative pressure is transmitted through a gas-liquid separation component, such as a sealed diaphragm or air bag, between the negative pressure side connected to the air pump and the milk storage assembly side. Both schemes can enable the negative pressure power to transmit negative pressure to the nipple and suck the milk into the milk storage container 12.

[0056] The milk storage assembly is provided with a milk collection space for storing milk, and the specific implementation has various forms. In some embodiments of the present application, the milk storage container 12 is provided as a milk bowl, the edge of the lower half of the breast shield 11 is integrally connected to the bowl opening of the milk bowl, the edge of the upper half of the breast shield 11 is sealingly covered on the milk storage container 12, and the elastic barrier 13 is detachably connected to the inner side of the breast shield 11, or the elastic barrier 13 is detachably connected to the milk storage container 12. In this scheme, the upper half of the breast shield 11 can be opened to clean the milk collection cavity 101 between the breast shield 11 and the milk storage container 12, and the elastic barrier 13 can be removed for cleaning separately.

[0057] In some embodiments of the present application, the elastic barrier 13 is at least partially integrally formed on the breast shield 11. The elastic barrier 13 can be integrally formed on the breast shield 11 in whole or in part. In some embodiments of the present application, the breast shield 11 comprises a bell-shaped cover for fitting the breast and a nipple passage 102 for accommodating the nipple, and the elastic barrier 13 is integrally formed on the end of the nipple passage 102.

[0058] In some embodiments of the present application, the elastic barrier 13 is at least partially integrally formed and sealed on the breast shield. In some other embodiments of the present application, the elastic barrier is integrally formed and sealed on the milk storage container. Accordingly, the breast shield 11 and the milk storage container 12 are two separate structures which can be detached, and the elastic barrier 13 can be integrally formed on the passage wall of the nipple passage 102 in whole, and specifically, the elastic barrier 13 is provided as a diaphragm, the periphery of which is integrally connected to the passage wall of the nipple passage 102, so that there is no sealing problem between the two, and the elastic barrier 13 cannot move relative to the passage wall of the nipple passage 102, and there is no problem of structural looseness.

[0059] The elastic barrier 13 can also be integrally formed and sealed on the breast shield in part, and specifically, for example, the elastic barrier 13 is provided as an elastic sealing cover, one side of which is formed with a flexible flange, and the elastic sealing cover is connected to the passage wall of the nipple passage 102 through the flexible flange, and the elastic sealing cover can rotate around the flexible flange to achieve the sealed connection and detachment of the elastic sealing cover and the passage wall of the nipple passage 102.

[0060] The elastic barrier 13 described above can be integrally connected to the inner wall surface, the outer wall surface or the end wall surface of the nipple passage 102, for example, the elastic barrier 13 is integrally connected to the outer wall surface of the nipple passage 102, and a communication hole is formed in the wall surface of the nipple passage 102 corresponding to the position of the elastic barrier 13, so that the elastic barrier 13 can change the air pressure in the nipple passage 102 by deformation, or the elastic barrier 13 is integrally connected to the inner side surface of the breast shield 11, and the elastic barrier 13 drives the breast shield 11 to deform when deformed, so that the air pressure in the nipple passage 102 is changed, and a negative pressure effect can be achieved.

[0061] The elastic barrier 13 can generate negative pressure in the milk storage assembly through elastic deformation, thereby facilitating the suction of milk from the user's breast. The specific way in which the elastic barrier 13 generates negative pressure in the milk storage assembly through elastic deformation is various. In some embodiments of the present application, the elastic barrier 13 is exposed. In use, the user can press the elastic barrier 13 to cause the gas in the milk storage assembly to be discharged from the gap between the breast shield and the user's breast, and then the user can attach the breast shield to the breast to make the milk storage assembly airtight. After the elastic barrier 13 returns to its original shape, negative pressure is generated in the milk storage assembly. Further, an exhaust passage is arranged on the inner side of the breast shield, and a one-way valve is arranged in the exhaust passage. The gas in the air bag nipple passage 102 is discharged, and the air bag returns to its original shape after the hand is released, thereby generating negative pressure in the nipple passage 102.
