[0052] The utility model provides a kind of breast pump 1.

[0053] Combination Figures 1 to 3 As shown in the drawing, in an embodiment of the utility model, breast pump 1 includes breast pumping assembly 10, one-way valve 20, negative pressure diaphragm 40 and connecting component;Breast pumping assembly 10 is formed with breast pumping passage 111 and milk storage space 121;One-way valve 20 is detachably connected with breast pumping assembly 10, and is communicated with breast pumping passage 111, and the other end is located in milk storage space 121, and breast pumping passage 111 is communicated with milk storage space 121 by one-way valve 20;Negative pressure diaphragm 40 is detachably connected to breast pumping assembly 10, and is used to provide negative pressure for breast pumping passage 111 when pumping milk;Connecting component is arranged in breast pumping assembly 10, and connecting component is connected with one-way valve 20, and connecting component is used to keep the connection of one-way valve 20 and breast pumping assembly 10 after one-way valve 20 is detached from breast pumping assembly 10;Or / and, connecting component is connected with negative pressure diaphragm 40, and connecting component is used to keep the connection of negative pressure diaphragm 40 and breast pumping assembly 10 after negative pressure diaphragm 40 is detached from breast pumping assembly 10.

[0054] Specifically, in the embodiment, breast pumping assembly 10 includes breast pumping shield 11 and milk bowl 12, wherein breast pumping shield 11 is formed with breast pumping passage 111, and breast pumping shield 11 and milk bowl 12 enclose to form milk storage space 121. When pumping milk, breast pumping shield 11 is covered outside breast, and nipple is in breast pumping passage 111, and under the action of negative pressure, milk is pumped out from breast and flows to milk storage space 121 through breast pumping passage 111.

[0055] The one-way valve 20 is detachably connected with the breast pumping assembly 10. Specifically, the one-way valve 20 can be connected with the breast pumping shield 11 or the milk bowl 12. The connection mode can be clamping, threaded connection, etc. The one-way valve 20 connects the breast pumping channel 111 and the milk storage space 121 to ensure that the milk can only flow from the breast pumping channel 111 to the milk storage space 121, preventing the occurrence of milk backflow.

[0056] The negative pressure diaphragm 40 is made of food-grade silicone or air-permeable liquid-impermeable material. The negative pressure diaphragm 40 is arranged at one end of the breast pumping channel 111. The negative pressure generated by the negative pressure pump 62 directly acts on the negative pressure diaphragm 40, causing the negative pressure diaphragm 40 to deform, thereby forming a negative pressure environment in the breast pumping channel 111; or the negative pressure diaphragm 40 pumps air out of the breast pumping channel 111, thereby forming a negative pressure environment in the breast pumping channel 111. By arranging the negative pressure diaphragm 40 to transmit negative pressure, the risk of milk flowing back into the negative pressure pump 62 can be effectively prevented, the negative pressure pump 62 can be kept clean, and the risk of milk contamination can also be avoided.

[0057] The negative pressure diaphragm 40 is detachably connected with the breast pumping assembly 10. The connection mode between the two can be clamping, threaded connection, etc. Since the negative pressure diaphragm 40 is small in size, it is easy to fall off, be lost or be omitted during cleaning or replacement of parts, resulting in the need for the user to purchase new accessories or the device being unable to work normally.

[0058] At the same time, since the one-way valve 20 is small in size, it is easy to fall off, be lost or be omitted during cleaning or replacement of parts, resulting in the need for the user to purchase new accessories or the device being unable to work normally.

[0059] Therefore, the application also provides a connecting component. The connecting component is connected with the breast pumping assembly 10, and is also connected with the one-way valve 20 and / or the negative pressure diaphragm 40. Specifically, the connecting component can be a single connecting piece having two connecting portions, which are respectively connected with the one-way valve 20 and the negative pressure diaphragm 40; or the connecting component can also include a first connecting piece 30 and a second connecting piece 50. The first connecting piece 30 is connected with the one-way valve 20, and the second connecting piece 50 is connected with the negative pressure diaphragm 40. The connection mode between the connecting component and the breast pumping assembly 10, the one-way valve 20 and the negative pressure diaphragm 40 can be detachable connection (such as clamping, sleeving or magnetic attraction connection) or non-detachable connection (such as adhesive bonding).

[0060] In addition, the connecting component can be connected to the breast pumping shield 11, the milk bowl 12 or other components of the breast pump 1.

[0061] This design ensures that when users remove the one-way valve 20 or negative pressure diaphragm 40 from the breast pump assembly 10 for cleaning or replacement, the one-way valve 20 or negative pressure diaphragm 40 remains suspended on the breast pump assembly 10 via the connecting parts, preventing accidental loss or omission during installation. This greatly improves the user experience and the reliability of the equipment.

[0062] The breast pump 1 also includes a negative pressure assembly 60, which includes a housing 61 and a negative pressure pump 62. The negative pressure pump 62 is disposed inside the housing 61. The negative pressure assembly 60 is connected to the milk expression assembly 10. At the same time, the negative pressure generated by the negative pressure pump 62 acts on the negative pressure diaphragm 40, so as to deform the negative pressure diaphragm 40 and form negative pressure in the milk expression channel 111 to provide negative pressure during milk expression.

[0063] Combination Figure 4 and Figure 5 As shown, in one embodiment of the present invention, the connecting components include a first connecting member 30 and a second connecting member 50. The first connecting member 30 is connected to the one-way valve 20 and the breast pumping assembly 10, respectively, and the second connecting member 50 is connected to the negative pressure diaphragm 40 and the breast pumping assembly 10, respectively.

[0064] In this embodiment, the connecting components include two parts: a first connector 30 and a second connector 50. Since the one-way valve 20 and the negative pressure diaphragm 40 are not arranged adjacent to each other, by setting the first connector 30 and the second connector 50, it is easier to connect the one-way valve 20 and the negative pressure diaphragm 40 to the adjacent breast pumping assembly 10, thereby improving the convenience of the structural layout.

[0065] In addition, the two ends of the first connector 30 can be detachably connected to the breast pump assembly 10 and the one-way valve 20, or they can be an integrally formed structure or other non-detachable connection methods. When the first connector 30 is detachably connected to the breast pump assembly 10 and the one-way valve 20, the specific connection method can be snap-fit, sleeve, snap-fit, or magnetic connection, etc.

[0066] The connection method between the second connector 50 and the negative pressure diaphragm 40 and the breast pumping assembly 10 is as described above, and will not be elaborated further here.

[0067] Combination Figure 2 and Figure 3 As shown, in one embodiment of the present invention, the breast pumping assembly 10 includes a breast pumping shield 11 and a milk bowl 12. The breast pumping shield 11 forms a breast pumping channel 111, and the breast pumping shield 11 and the milk bowl 12 enclose a milk storage space 121. One end of the first connector 30 is connected to the breast pumping shield 11, and the other end is connected to the outer periphery of the one-way valve 20.

[0068] In this embodiment, as Figure 3As shown, the breast shield 11 has a large volume, and thus connecting one end of the first connecting member 30 to the breast shield 11 can further improve the effect of preventing the loss of the one-way valve 20. In addition, since the one-way valve 20 is located between the breast shield 11 and the milk bowl 12, the one-way valve 20 is relatively close to the breast shield 11 and the milk bowl 12. Therefore, compared with being connected to other structures, such as the shell 61, the design of the present application can shorten the length of the first connecting member 30 and avoid the long first connecting member 30 occupying more internal space of the breast pump 1.

[0069] In an embodiment of the present application, one end of the first connecting member 30 is detachably connected to the breast shield 11. Therefore, when cleaning or replacing other accessories, the one-way valve 20 can be hung on the breast shield 11 through the first connecting member 30 after being detached from the breast shield 11. When the one-way valve 20 needs to be replaced or cleaned separately, the first connecting member 30 can be separated from the breast shield 11 to meet different user needs.

[0070] Specifically, the first connecting member 30 and the breast shield 11 can be connected in various ways, such as buckle connection, in which one end of the first connecting member 30 is provided with a buckle structure that can be quickly and stably buckled into a corresponding slot on the breast shield 11; magnetic adsorption, in which a magnet is arranged between the first connecting member 30 and the breast shield 11 to achieve stable adsorption by magnetic force; threaded sealing connection, in which one end of the first connecting member 30 is designed as a threaded structure that cooperates with a threaded hole on the breast shield 11 to achieve tight connection by rotation.

[0071] In other embodiments, the other end of the first connecting member 30 can also be detachably connected to the one-way valve 20. The specific connection method can be referred to the above description, and will not be further described here.

[0072] In combination Figure 6 As shown, in an embodiment of the present application, one end of the first connecting member 30 is provided with a first connecting ring 31, and the first connecting ring 31 is sleeved on the outer periphery of the breast shield 11.

[0073] In the embodiment, the outer shape of the breast shield 11 is trumpet-shaped to facilitate the adaptation and fit with the breast. Therefore, the first connecting ring 31 is arranged at the end of the first connecting piece 30, and the annular structure of the first connecting ring 31 can better adapt to the outer shape of the breast shield 11. Therefore, when the first connecting piece 30 is disassembled from the breast shield 11, the first connecting ring 31 only needs to be sleeved on the outer periphery of the breast shield 11, thereby improving the convenience of disassembling the first connecting piece 30 from the breast shield 11. Further, the first connecting ring 31 is designed to have a certain elasticity to facilitate installation and disassembly, and to adapt to the outer periphery of the breast shield 11 of different sizes.

[0074] In combination Figure 6 As shown in the embodiment of the utility model, the outer periphery of the breast shield 11 is annularly provided with a limiting groove 112, and the first connecting ring 31 is embedded in the limiting groove 112.

[0075] In the embodiment, the design of the limiting groove 112 plays a positioning role on the installation position of the first connecting ring 31. By embedding the first connecting ring 31 in the limiting groove 112, the problem of loosening or falling off of the first connecting piece 30 from the breast shield 11 due to external vibration or collision is avoided, and the stability and reliability of the connection between the first connecting piece 30 and the breast shield 11 are improved. The limiting groove 112 is located at the end of the breast shield 11 with smaller size, so that the size of the first connecting ring 31 can be designed to be smaller to reduce the structural cost. In addition, by embedding the first connecting ring 31 in the limiting groove 112, the volume of the first connecting ring 31 protruding from the surface of the breast shield 11 can be reduced, the compactness of the structure and the aesthetic appearance are improved, and the risk of damage of the first connecting ring 31 caused by friction with other components during disassembly is also reduced.

[0076] In combination Figure 9 As shown in the embodiment of the utility model, the breast assembly 10 comprises the breast shield 11 and the milk bowl 12. The breast shield 11 forms a breast pumping passage 111, and the breast shield 11 and the milk bowl 12 form a milk storage space 121. One end of the first connecting piece 30 is connected to the milk bowl 12, and the other end is connected to the outer periphery of the one-way valve 20.

[0077] In the embodiment, since the distance between the one-way valve 20 and the milk bowl 12 is also small, connecting one end of the first connecting piece 30 to the milk bowl 12 can also shorten the length of the first connecting piece 30 and reduce the structural cost. Further, the first connecting piece 30 and the milk bowl 12 are also arranged to be detachably connected to facilitate the disassembly and replacement of the one-way valve 20. Specifically, as shown in the embodiment of the utility model, Figure 9As shown, one end of the first connecting piece 30 is provided with one of the clamping protrusion 14 or the clamping hole, and the milk bowl 12 is provided with the other one of the clamping protrusion 14 or the clamping hole. When the first connecting piece 30 is connected with the milk bowl 12, the clamping protrusion 14 is buckled in the clamping hole, so that the first connecting piece 30 is detachably connected with the milk bowl 12.

[0078] In another embodiment, the breast pumping assembly 10 further comprises a milk cover, the milk cover is arranged at the opening of the milk bowl 12 and forms the milk storage space 121 together with the milk bowl 12, and the surface of the milk cover is provided with a milk inlet port, the milk inlet port is communicated with the milk pumping channel 111. In this embodiment, the negative pressure diaphragm 40 is connected with the milk cover through the second connecting piece 50, and the connection mode can be detachable connection or non-detachable connection. Of course, the one-way valve 20 can also be connected with the milk cover through the first connecting piece 30.

[0079] In combination Figures 2 to 6 As shown, in an embodiment of the utility model, the breast pumping assembly 10 comprises a breast pumping shield 11, a flange 13 and a milk bowl 12, the breast pumping shield 11 is formed with a milk pumping channel 111, the breast pumping shield 11 and the milk bowl 12 form a milk storage space 121 together, one end of the breast pumping shield 11 is used for being attached to the breast, the flange 13 is connected to the other end of the breast pumping shield 11, and the one-way valve 20 is detachably connected to the flange 13.

[0080] The one end of the first connecting piece 30 is connected to the flange 13, and the other end is connected to the outer periphery of the one-way valve 20.

[0081] In this embodiment, the flange 13 is made of elastic material, for example, silica gel or rubber. The flange 13 is arranged at the end of the breast pumping shield 11, and the breast pumping shield 11, the milk bowl 12 and the one-way valve 20 are connected together through the flange 13, so that the integration degree of the structure is improved. Specifically, the flange 13 is detachably connected to the breast pumping shield 11 through thread connection or clamping, and forms a milk outlet port communicated with the milk pumping channel 111 together with the breast pumping shield 11. One end of the one-way valve 20 is connected to the flange 13 and communicated with the milk outlet port, and the other end is embedded in the milk storage space 121 to prevent backflow of milk. Since the breast pumping shield 11 is connected to the milk bowl 12 through the flange 13, and the one-way valve 20 is detachably connected to the flange 13, one end of the first connecting piece 30 is connected to the flange 13, so that the first connecting piece 30 has a shorter length, which facilitates the connection of the first connecting piece 30 with the breast pumping assembly 10 and the one-way valve 20, and reduces the cost of the structure.

[0082] In an embodiment of the utility model, one end of first connecting piece 30 is detachably connected with flange 13. Therefore, when cleaning or replacing other accessories, one-way valve 20 is detached from flange 13, and first connecting piece 30 can keep one-way valve 20 hanging on flange 13. When one-way valve 20 needs to be replaced or cleaned separately, first connecting piece 30 can be separated from flange 13 to meet different use requirements of users.

[0083] Specifically, the connecting mode of first connecting piece 30 and flange 13 can be various, for example, buckle type connection, one end of first connecting piece 30 is provided with a buckle structure, which can be quickly and stably buckled into the corresponding slot on flange 13; magnetic adsorption, a magnet is arranged between first connecting piece 30 and flange 13, and the magnet is used to realize stable adsorption by magnetic force; threaded sealing connection, one end of first connecting piece 30 is designed as a threaded structure, which is matched with the threaded hole on flange 13 to realize tight connection by rotating.

[0084] In other embodiments, the other end of first connecting piece 30 can also be detachably connected with one-way valve 20, and the specific connecting mode can refer to the above description, which will not be described further.

[0085] In combination with Figure 5 As shown in the utility model, in an embodiment of the utility model, one end of first connecting piece 30 is provided with one of clamping convex 14 or clamping hole, and the other of clamping convex 14 or clamping hole is arranged on the outer periphery of flange 13, clamping convex 14 is buckled in the clamping hole to detachably connect first connecting piece 30 with flange 13.

[0086] Alternatively, one end of first connecting piece 30 is provided with first connecting ring 31, and first connecting ring 31 is sleeved on the outer periphery of flange 13.
