[0027] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0028] like Figures 1 to 3The illustrated breast pump assembly includes a flexible outer shell 1 and a flexible inner liner 2. The flexible outer shell 1 has a front-open cavity and a flexible diaphragm 3 that divides the cavity into a front cavity 11 and a rear cavity 12. The flexible inner liner 2 includes a plug-in post 21 that can be inserted into the front cavity 11. The front end of the plug-in post 21 has a breast-suction concave cavity 211 that communicates with the front cavity 11 and a fitting cover 22 that can fit against the breast to guide milk into the breast-suction concave cavity 211. The rear cavity 12 can deform the flexible diaphragm 3 under the action of a negative pressure source to create negative pressure in the breast-suction concave cavity 211. The flexible outer shell 1 and the flexible inner liner 2 also have a milk discharge channel 4 that can discharge milk from the breast-suction concave cavity 211. The front cavity 11 also has a support frame 5 for increasing the rigidity of the side wall of the front cavity 11. The support frame 5 is sleeved on the outside of the plug-in post 21.

[0029] The flexible outer shell 1 and flexible inner liner 2 of the breast pump assembly in this case are both made of flexible materials, which can better adapt to the shape of the breast and reduce discomfort during use. The flexible materials can simulate the way a baby sucks to provide a more natural sucking experience. Flexible materials are often lighter and easier to carry than products made of traditional hard plastic or glass, making them convenient for use when going out. The front cavity 11 is equipped with a support frame 5, which enhances the rigidity of the breast pump assembly and ensures that its performance will not be affected by excessive deformation during use.

[0030] In some embodiments, both the flexible outer shell 1 and the flexible inner liner 2 can be made of silicone, or other food-grade flexible materials.

[0031] In some embodiments, the rear end of the support frame 5 is provided with a milk shield 51 for limiting milk contact with the flexible diaphragm 3, wherein the milk shield 51 and the support frame 5 are an integral structure.

[0032] Specifically, the cross-section of the breast shield 51 is arc-shaped or rectangular, and the flexible diaphragm 4 is attached to the breast shield 51 under normal pressure in the rear cavity 12. Among these, a wavy cross-section of the breast shield 51 is the optimal solution.

[0033] Furthermore, the flexible diaphragm 4 can be made of breathable silicone, or other flexible materials. The upper part of the milk-absorbing shield 51 is provided with an air vent 52 that connects the milk-absorbing cavity 211 to the flexible diaphragm 3. The air vent 52 is an oblique hole with a lower front end and a higher rear end, thereby further limiting milk splashing onto the flexible diaphragm 4, thus preventing the flexible diaphragm 4 from contacting milk and altering its performance, affecting the milk-absorbing effect.

[0034] In some embodiments, the front end of the support frame 5 is provided with a plug-in portion 53, and the back of the fitting cover 22 is provided with a first plug-in groove 23 for the plug-in portion 53 to be inserted, thereby making the connection between the flexible inner liner 2 and the support frame 5 more stable and less prone to loosening.

[0035] Furthermore, the outer back wall of the flexible liner 2 and the outer wall of the support frame 5 are provided with a first annular protrusion 50 to increase the friction between the flexible liner 2 and the inner wall of the front cavity 11, thereby making the connection of the flexible liner 2 more stable.

[0036] In some embodiments, a cover 6 that can open the rear cavity 12 is connected to the flexible outer shell 1. The cover 6 or the flexible outer shell 1 is provided with an air pipe interface 61 communicating with the rear cavity 12. An annular tube 7 is provided between the cover 6 and the flexible outer shell 1 to increase the rigidity of the sidewall of the rear cavity 12. The air pipe interface 61 allows the user to easily connect a negative pressure source via an air pipe, making operation simple and convenient. The negative pressure source can be an air pump or other suction device. The annular tube 7 can further strengthen the rigidity of the milk suction bowl assembly and improve the milk suction performance.

[0037] In one embodiment, the annular tube 7 can be an independent structure, with its outer wall supported on the inner wall of the rear cavity 12. This increases the rigidity of the sidewall of the rear cavity 12 and reduces the deformation of the sidewall when the rear cavity 12 is under negative pressure.

[0038] In some embodiments, the cover 6 is made of a rigid material, such as rigid plastic or rigid silicone. The annular tube 7 is connected to the inner side of the cover 6 and is an integral part of the cover 6. The annular tube 7 is inserted into the rear cavity 12. Alternatively, a second insertion groove 13 can be formed on the rear end of the side wall of the rear cavity 12, into which the annular tube 7 is inserted. While supporting the side wall of the rear cavity 12, the annular tube 7 can also connect the cover 6 to the flexible outer shell 1, with friction preventing the annular tube 7 from retracting.

[0039] In some embodiments, the milk discharge channel 4 is located at the lower part of the flexible outer shell 1 and the flexible inner liner 2. The flexible outer shell 1 is also provided with a first connecting pipe 14 for connecting the milk storage device 9. The inner cavity of the first connecting pipe 14 is in communication with the milk discharge channel 4.

[0040] Furthermore, the flexible outer shell 1, the flexible diaphragm 3, and the first connecting pipe 14 are integrally formed. This reduces the number of parts, facilitates disassembly and cleaning, and also reduces installation steps, thereby improving production efficiency.

[0041] Furthermore, the lower part of the flexible outer shell 1 is connected to a guide member 8 for discharging milk from the milk-suction cavity 211. The input end of the guide member 8 is connected to the output end of the milk-discharging channel 4. The output end of the guide member 20 is a narrowed opening, which has a certain anti-backflow effect.

[0042] This invention also provides a breast pump, including a negative pressure source and a milk suction bowl assembly, wherein the milk suction bowl assembly is the same as the milk suction bowl assembly described in the above embodiment.

[0043] Furthermore, the aforementioned breast pump also includes a milk storage unit 9, the input end of which is provided with a connecting neck 91 that can be connected to the first connecting pipe 14. The connecting neck 91 can be fastened to the first connecting pipe 14 via a snap-fit ​​structure, or it can be connected to the first connecting pipe 14 via a threaded structure or other connecting structures.

[0044] Furthermore, the lower part of the flexible outer shell 1 is also provided with a second connecting pipe 15, which is located inside the first connecting pipe 14 and is sleeved with the guide member 8. The inner wall of the second connecting pipe 15 has a second annular protrusion to increase the friction between it and the guide member 8, thereby preventing the guide member 8 from detaching. Of course, the guide member 8 can also be connected to the second connecting pipe 15 via a threaded structure or other connection structure.

[0045] Furthermore, the flexible outer shell 1, flexible diaphragm 3, first connecting pipe 14, and second connecting pipe 15 are integrally formed. This reduces the number of parts, facilitates disassembly and cleaning, and also reduces installation steps, thereby improving production efficiency.

[0046] In one embodiment, a milk storage chamber communicating with the milk suction cavity can be provided inside the flexible shell 1 to replace the milk storage device. The flexible shell 1 is provided with a milk discharge structure for discharging milk from the milk storage chamber.

[0047] This utility model provides a breast pump assembly and a breast pump, including a flexible outer shell 1 and a flexible inner liner 2. The flexible outer shell 1 has a front-open cavity and a flexible diaphragm 3 that divides the cavity into a front cavity 11 and a rear cavity 12. The flexible inner liner 2 includes a plug-in post 21 that can be inserted into the front cavity 11. The front end of the plug-in post 21 has a breast-suction cavity 211 that communicates with the front cavity 11 and a fitting cover 22 that can fit against the breast to guide milk into the breast-suction cavity 211. The rear cavity 12 can deform the flexible diaphragm 3 under the action of a negative pressure source to create negative pressure in the breast-suction cavity 211. The flexible outer shell 1 and the flexible inner liner 2 are also provided with a milk discharge channel 4 that can discharge milk from the breast-suction cavity 211. The front cavity 11 is also provided with a support frame 5 for increasing the rigidity of the side wall of the front cavity 11. The support frame 5 is sleeved on the outside of the plug-in post 21. Both the flexible outer shell 1 and the flexible inner liner 2 are made of flexible materials, which can better adapt to the shape of the breast and reduce discomfort during use. The flexible materials can simulate the way a baby sucks to provide a more natural sucking experience. Flexible materials are often lighter and easier to carry than products made of traditional hard plastic or glass, making them convenient for use when going out. The front cavity 11 has a support frame 5, which enhances the rigidity of the breast cup assembly and ensures that its performance will not be affected by excessive deformation during use.
