Description

Technical Field

[0001] This application relates to the field of maternal and infant device technology, and in particular to a breast pump and a one-way valve. Background Technology

[0002] Among modern breastfeeding support devices, the breast pump is a very important device that helps mothers collect breast milk when direct breastfeeding is not possible. A breast pump typically includes a milk tube, a milk storage container, and a necessary valve system to control the flow of milk. The one-way valve is a key component; its main function is to ensure that milk flows only from the breast to the storage container, preventing backflow and thus guaranteeing hygiene and comfort.

[0003] Traditional one-way valve designs often have several problems, especially under long-term or high-frequency use. For example, the connection between the one-way valve and the milk tubing or other connections on the breast pump may not be stable enough, leading to air leaks or milk leakage. Furthermore, if the elastic material of the one-way valve is not chosen appropriately, frequent opening and closing may cause its elasticity to weaken, affecting sealing performance or even causing complete failure. These problems not only reduce the overall efficiency of the breast pump but also cause inconvenience to users and increase the risk of cross-contamination. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a breast pump and a one-way valve, which can solve the problems of unstable connection or insufficient flexibility of the one-way valve.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application embodiment is: providing a breast pump, the breast pump comprising: a milk suction tube, wherein a milk guiding channel is formed within the milk suction tube; a milk storage container, wherein a milk storage space is formed within the milk storage container, the milk storage space being used to receive milk flowing out through the milk guiding channel; and a one-way valve, the one-way valve being disposed between the milk guiding channel and the milk storage space, and the one-way valve being configured to allow milk to flow unidirectionally from the milk guiding channel to the milk storage space; the one-way valve comprising a connecting portion and a valve body connected to the connecting portion, the hardness of the connecting portion being greater than the hardness of the valve body.

[0011] Optionally, the connecting part is provided with a first connecting structure, and the diaphragm support is provided with a second connecting structure. The first connecting structure and the second connecting structure are matched to realize the detachable connection between the one-way valve and the diaphragm support.

[0012] Optionally, the diaphragm support has a groove formed to at least partially accommodate the one-way valve.

[0013] Optionally, the breast pump further includes a diaphragm for placement within the negative pressure chamber. The diaphragm divides the internal space of the diaphragm support into a first subspace and a second subspace. The first subspace is connected to the negative pressure interface of the negative pressure source, and the second subspace is connected to the internal space of the milk suction tube. The diaphragm can deform within the internal space of the diaphragm support under the negative pressure provided by the negative pressure source to transmit negative pressure.

[0014] Optionally, the valve body of the one-way valve is a disc valve or a duckbill valve.

[0015] To solve the above-mentioned technical problems, another technical solution adopted in this application embodiment is: to provide a one-way valve, the one-way valve including a connecting part and a valve body connected to the connecting part, wherein the hardness of the connecting part is greater than the hardness of the valve body.

[0032] like Figure 1 , Figure 2 , Figure 3 As shown, in this embodiment, the breast pump may include: a milk suction tube 10, a milk storage container 20, and a one-way valve 30.

[0033] A milk-guiding channel 11 is formed within the milk suction tube 10. The milk-guiding channel 11 is used to receive milk from the breast.

[0034] The milk storage container 20 has a milk storage space 21, which is used to receive milk flowing out through the milk guide channel 11. A one-way valve 30 is provided in the passage between the milk guide channel 11 and the milk storage space 21, and the one-way valve 30 is configured to allow milk to flow unidirectionally from the milk guide channel 11 into the milk storage space 21.

[0035] Milk in the milk channel 11 flows directly or indirectly into the milk storage space 21. "Directly" means the milk in the milk channel 11 flows directly through the opening on the milk suction tube 10 into the milk storage space 21. "Indirectly" means the milk in the milk channel 11 flows out of the milk channel 11, first through the negative pressure chamber, and then through the opening on the diaphragm support 40 into the milk storage container 20. A one-way valve 30 is disposed in the passage between the milk channel 11 and the milk storage space 21. For example, the one-way valve 30 can be connected to the diaphragm support 40 and disposed in the passage between the negative pressure chamber and the milk storage space 21; or, for another example, the one-way valve can be connected to the milk suction tube 10 and disposed in the passage between the milk channel 11 and the milk storage space 21. This application does not limit this specific placement, as long as the one-way valve 30 is disposed in the passage between the milk channel 11 and the milk storage space 21. The specific placement of these two types of one-way valves can be found in the description below.

[0036] like Figure 4 , 5 As shown in Figure 6, the one-way valve 30 includes a connecting portion 31 and a valve body 32 connected to the connecting portion 31. The hardness of the connecting portion 31 is greater than that of the valve body 32. For example, the connecting portion 31 can be made of hard plastic, and the valve body 32 can be made of soft plastic.

[0037] In some embodiments, the connecting portion 31 and the valve body 32 may be integrally formed. Alternatively, the connecting portion 31 and the valve body 32 may be integrally injection molded from soft and hard plastic.

[0038] like Figure 6 As shown, in some embodiments, the breast pump may also include a diaphragm support 40, in which a negative pressure chamber 41 is formed, and the negative pressure chamber 41 is connected to the milk channel 11.

[0039] In some embodiments, a one-way valve 30 is connected to a diaphragm support 40. A milk outlet 42 is provided on the diaphragm support 40, and the one-way valve 30 is located at the milk outlet 42. A negative pressure vent 12 is provided on the milk suction pipe 10, and the milk guiding channel 11 and the negative pressure chamber 40 are connected through the negative pressure vent 12. Milk first flows into the negative pressure chamber 40 through the negative pressure vent 12 and then flows through the milk outlet 42 to the milk storage space 21.

[0040] Optionally, the valve body 32 of the one-way valve 30 can be a plate valve. When negative pressure is applied to the milk channel 11, milk is drawn out, and the plate valve adheres tightly to the milk outlet 42 under negative pressure, thereby preventing milk backflow in the milk storage space 21. During the period when the negative pressure is released, the milk pushes open the plate valve under gravity and flows into the milk storage space 21. In some embodiments, the valve body of the one-way valve can also be a duckbill valve.

[0041] like Figure 2 , Figure 3 , Figure 5 As shown, in one embodiment, a first connecting structure 311 is provided on the connecting portion 31, and a second connecting structure 43 is provided on the diaphragm support 40. The first connecting structure 311 and the second connecting structure 43 are matched to achieve a detachable connection between the one-way valve 30 and the diaphragm support 40. One of the first connecting structure 311 and the second connecting structure 43 is a snap-fit, and the other is a slot. Optionally, the snap-fit ​​is provided on the diaphragm support 40, and the slot is provided on the connecting portion 31.

[0042] like Figure 2 and Figure 5 As shown, in one embodiment, the diaphragm support 40 has a groove 44 formed on it to at least partially accommodate the one-way valve 30. In this way, the overall thickness of the milk bowl assembly 20 can be reduced, avoiding the one-way valve 30 occupying additional thickness space.

[0043] In one embodiment, the breast pump further includes a diaphragm 50, which is placed inside the negative pressure chamber 41. The diaphragm 50 divides the internal space of the diaphragm support 40 into a first subspace and a second subspace. The first subspace is connected to the negative pressure interface of the negative pressure source, and the second subspace is connected to the internal space of the milk suction tube 10. The diaphragm 50 can deform within the internal space of the diaphragm support 40 to transmit negative pressure under the negative pressure provided by the negative pressure source.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the breast pump may further include a main unit 60, and the negative pressure source may be provided by a negative pressure pump of the main unit 60. The negative pressure pump inside the main unit 60 is connected to a negative pressure interface 61, which is connected to the aforementioned first subspace. In some embodiments, the negative pressure source may be provided by an external negative pressure device, or by a manual negative pressure generating device; this application does not limit the specific embodiment in this regard.

[0045] In some embodiments, the breast pump further includes a breast shield 70 having a narrow end 71 and a wide end 72, and a through hole 62 provided on the main body 60. The narrow end 71 of the breast shield 70 passes through the through hole 62, and the main body 60 is at least partially located between the wide end 72 of the breast shield 70 and the milk storage container 20.

[0046] In some embodiments, the milk storage container 20 can be a milk bowl assembly 20, which includes a bowl body 22 and a cover plate 23, and the bowl body 22 and the cover plate 23 enclose a milk storage space 21.

[0047] In some embodiments, both the milk suction tube 10 and the diaphragm support 40 are connected to the milk storage container 20. In one embodiment, both the milk suction tube 10 and the diaphragm support 40 may be connected to the cover plate 23.

[0048] In some embodiments, both the milk suction tube 10 and the diaphragm support 40 extend into the milk storage space 21.

[0049] See Figure 7-Figure 8 , Figure 7 This is a schematic diagram of the structure of the one-way valve and the breast pump tube in an assembled state according to another embodiment of this application; Figure 8 This is a schematic diagram of the structure of another embodiment of the present application with the one-way valve and the breast pump tube separated.

[0050] In some embodiments, the one-way valve 80 may also be connected to the milk suction tube 90. The end of the milk suction tube 90 away from the cover plate 100 is provided with a milk outlet 91. The one-way valve 80 is located at the milk outlet 91. The milk flows directly to the milk storage space 21 through the milk outlet 91 without passing through the negative pressure chamber inside the diaphragm support 101.

[0051] This application embodiment describes a breast pump comprising: a milk suction tube with a milk guiding channel formed within it; a milk storage container with a milk storage space formed within it, the milk storage space being used to receive milk flowing out through the milk guiding channel; and a one-way valve disposed between the milk guiding channel and the milk storage space, the one-way valve being configured to allow milk to flow unidirectionally from the milk guiding channel into the milk storage space; the one-way valve includes a connecting portion and a valve body connected to the connecting portion, the connecting portion being harder than the valve body, the harder connecting portion providing a stable connection, and the less hard valve body improving elasticity, thereby improving the rebound effect of the valve body, ensuring the normal function of the one-way valve, and improving the elasticity and performance of the one-way valve while ensuring the connection stability of the one-way valve.
