Description
Technical Field
[0001] This utility model relates to the field of breast pump technology, and in particular to a hands-free breast pump shield for use in breast pumps. Background Technology
[0002] The hands-free breast pump is an innovative maternal and infant product designed specifically for breastfeeding women. Through wearable structure, intelligent drive technology and user-friendly design, it eliminates the need for hand support during breastfeeding, balancing efficient lactation with ease of use.
[0003] For example, Chinese invention patent application CN114515361A discloses an integrated breast pump, namely a hands-free breast pump, comprising a shell, an adapter, a negative pressure generating device, a negative pressure transmitting component, and a one-way valve. The shell contains a T-junction integrally formed with the shell. The funnel-shaped adapter has a liquid inlet that is detachably fitted onto the shell, and the liquid inlet is connected to the liquid inlet. The negative pressure generating device has a suction port that provides periodic negative pressure and is connected to the shell. A negative pressure transmitting component is located at the negative pressure port, and the suction port is connected to the negative pressure transmitting component, causing it to deform periodically. The one-way valve is connected to the liquid outlet. Through this structural design, the T-junction is integrally formed with the shell, making the product compact, airtight, and stable. The lower surface of the adapter conforms to the surface of the breast, providing a more comfortable experience for the user. The upper surface of the funnel-shaped adapter and the inner surface of the shell form a receiving space, effectively utilizing space and reducing volume. The structure is simple and compact, the internal design is reasonable, and the product is small in size, making it convenient for users to carry and use. However, the product uses a three-way connector to connect the negative pressure port, liquid inlet and liquid outlet, which makes the structure complex, has many parts, and is difficult to disassemble and clean.
[0004] Therefore, existing technologies still need to be improved and developed to address the aforementioned shortcomings. Utility Model Content
[0005] The purpose of this invention is to address the defects and deficiencies mentioned in the background section by providing a hands-free breast pump cover.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] This utility model provides a hands-free breast pump cover for a breast pump, comprising a milk bowl and a breast adapter. The breast adapter has a liquid inlet and is detachably fitted onto the milk bowl. A milk storage cavity is formed between the milk bowl and the breast adapter. A flow channel support and an integrated component are detachably fixed between the milk bowl and the breast adapter. The flow channel support has an inlet and an outlet. The inlet is connected to the liquid inlet of the breast adapter, and the outlet is detachably connected to the integrated component. It should be noted that the integrated component and the outlet must be tightly connected, and the integrated component includes interconnected components. The device includes a negative pressure conductor and a one-way valve. A sealed air pressure cavity is formed between the negative pressure conductor and the milk bowl. The air pressure cavity has a connection hole for connecting a negative pressure generating device. The one-way valve is connected to the milk storage cavity. More specifically, the milk bowl and the breast adapter can enclose the milk storage cavity. The liquid outlet of the one-way valve is placed inside the milk storage cavity. Alternatively, a milk storage structure connected to the one-way valve can be added between the milk bowl and the breast adapter. This milk storage structure has a milk storage cavity. During the milk expression process, the breast milk can be temporarily stored in the milk storage cavity. The negative pressure generating device can be an air pump. The flow channel support of this utility model simplifies the existing three-way component into a two-way component. The inlet of the flow channel support is connected to the liquid guide port of the breast adapter, and the outlet of the flow channel support is sealed by an integrated component. The integrated component is equipped with a negative pressure transmission component and a one-way valve for discharging liquid. This design can not only realize the transmission of negative pressure, but also simplify the internal structure of the breast cup composed of the milk bowl and the breast adapter, making it easier for consumers to disassemble and clean.
[0008] According to the above scheme, a support frame is fixedly provided inside the milk bowl, and the integrated component is detachably installed on the support frame. A pneumatic cavity is formed between the negative pressure transmission component and the support frame. With the above structural arrangement, during assembly, the integrated component can be first installed on the support frame, and then the liquid outlet of the flow channel support can be adapted to the integrated component. This not only achieves the connection between the liquid outlet and the integrated component, but also achieves the limiting and fixing of the flow channel support.
[0009] According to the above scheme, the negative pressure conducting element is a thin film structure with a corrugated surface, and the negative pressure conducting element can deform with periodic negative pressure. Through this structural design, when connected to a negative pressure generating device, the negative pressure conducting element is facilitated to undergo periodic deformation, while simultaneously reducing fatigue damage and localized wear.
[0010] According to the above scheme, the negative pressure transmitting component and the one-way valve are integrally formed. This structural design facilitates the disassembly, cleaning, and assembly of the negative pressure transmitting component and the one-way valve together. Preferably, the negative pressure transmitting component, the one-way valve, and other parts of the integrated component are made of elastic rubber material.
[0011] According to the above scheme, the end faces of the negative pressure conductor and the one-way valve connected to each other are flush, that is, the end face of the negative pressure conductor facing the flow channel support and the end face of the one-way valve facing the flow channel support are flush. This structural arrangement makes the integrated component easier to clean and easier to demold during production.
[0012] According to the above scheme, the one-way valve is a duckbill valve. Through the above structural design, the duckbill valve, with its elastic material properties and mechanical-free design, possesses excellent sealing performance, anti-clogging capabilities, and low maintenance.
[0013] According to the above scheme, the flow channel support is configured as a "7"-shaped structure consisting of a horizontal section and an inclined section. A liquid channel is formed inside the flow channel support. The liquid inlet is located at the free end of the horizontal section, and the liquid outlet is located at the bottom of the inclined section. The liquid inlet and outlet are connected to the liquid channel. More specifically, the inclined section is located in the lower middle position inside the milk bowl. The horizontal section is cylindrical, and the inclined section is flat, with the flat shape facilitating connection with the cover plate. This structural configuration facilitates the placement of the flow channel support inside the milk bowl.
[0014] According to the above design, the upper end of the milk bowl is provided with a milk inlet, which is connected to the milk storage chamber. Through this structural arrangement, during the milk expression process, the milk inlet connects the milk storage chamber to the outside, ensuring that breast milk can flow into the milk storage chamber from the one-way valve. After expression, the breast milk can be poured out and transferred through the milk inlet.
[0015] According to the above design, the breast adapter is shaped like a trumpet, and the fluid inlet is located at the smaller diameter end of the trumpet shape. This structural design allows the breast adapter to fit the breast more closely.
[0016] According to the above design, the edge of the breast adapter is detachably fastened to the edge of the milk bowl. This structural design allows consumers to easily disassemble and assemble this invention themselves.
[0017] The beneficial effects of this utility model are:
[0018] The flow channel support of this utility model simplifies the existing three-way component into a two-way component. The inlet of the flow channel support is connected to the liquid guide port of the breast adapter, and the outlet of the flow channel support is sealed by an integrated component. The integrated component is equipped with a negative pressure transmission component and a one-way valve for discharging liquid. This design can not only realize the transmission of negative pressure, but also simplify the internal structure of the breast cup composed of the milk bowl and the breast adapter, making it easier for consumers to disassemble and clean.

[0023] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.
[0024] Example 1
[0025] like Figure 1-3 As shown, this utility model provides a hands-free breast pump cover for a breast pump, including a milk bowl 1 and a breast adapter 2. The breast adapter 2 is provided with a liquid inlet 21. The breast adapter 2 is detachably fitted onto the milk bowl 1, and a milk storage cavity 3 is formed between the milk bowl 1 and the breast adapter 2. A flow channel support 4 and an integrated component 5 are detachably fixed between the milk bowl 1 and the breast adapter 2. The flow channel support 4 is provided with an inlet 41 and an outlet 42. The inlet 41 is connected to the liquid inlet 21 of the breast adapter 2, and the outlet 42 is detachably connected to the integrated component 5. It should be noted that... The integrated component 5 needs to be tightly connected to the outlet 42. The integrated component 5 includes a negative pressure conductor 51 and a one-way valve 52 connected to each other. A sealed air pressure cavity 6 is formed between the negative pressure conductor 51 and the milk bowl 1. The air pressure cavity 6 is provided with a connection hole 61 for connecting a negative pressure generating device. The one-way valve 52 is connected to the milk storage cavity 3. More specifically, the milk bowl 1 and the breast adapter 2 enclose the milk storage cavity 3. The outlet end of the one-way valve 52 is placed inside the milk storage cavity 3. During the milk expression process, the breast milk can be temporarily stored in the milk storage cavity 3. The negative pressure generating device can be an air pump. Figure 2 This is a diagram showing the usage state when the air inside the pneumatic chamber 6 is not extracted. Figure 3This diagram shows the usage state when air is extracted from the pneumatic chamber 6. The flow channel support 4 of this invention simplifies the existing three-way connector into a two-way connector. The inlet 41 of the flow channel support 4 is connected to the outlet 21 of the breast adapter 2, and the outlet 42 of the flow channel support 4 is sealed by an integrated component 5. The integrated component 5 is equipped with a negative pressure transmission component 51 and a one-way valve 52 for discharging liquid. This design not only achieves negative pressure transmission but also simplifies the internal structure of the breast cup consisting of the milk bowl 1 and the breast adapter 2, making it easier for consumers to disassemble and clean.
[0026] Furthermore, a support frame 11 is fixedly installed inside the milk bowl 1, and the integrated component 5 is detachably installed on the support frame 11. A pneumatic cavity 6 is formed between the negative pressure conducting component 51 and the support frame 11. With the above structural arrangement, during assembly, the integrated component 5 can be first installed on the support frame 11, and then the liquid outlet 42 of the flow channel support 4 can be adapted to the integrated component 5. This not only achieves the connection between the liquid outlet 42 and the integrated component 5, but also achieves the limiting and fixing of the flow channel support 4.
[0027] Furthermore, the negative pressure conductor 51 has a corrugated curved thin film structure, and the negative pressure conductor 51 can deform with periodic negative pressure. Through this structural design, when connected to the negative pressure generating device, the negative pressure conductor 51 can easily undergo periodic deformation, while simultaneously reducing fatigue damage and localized wear.
[0028] Furthermore, the negative pressure conductor 51 and the one-way valve 52 are integrally formed. This structural arrangement facilitates the disassembly, cleaning, and assembly of the negative pressure conductor 51 and the one-way valve 52 together. In this preferred embodiment, the negative pressure conductor 51, the one-way valve 52, and other parts of the integrated component 5 are all made of elastic rubber material.
[0029] The end faces of the negative pressure conductor 51 and the one-way valve 52 connected to each other are flush, that is, the end face of the negative pressure conductor 51 facing the flow channel support 4 and the end face of the one-way valve 52 facing the flow channel support 4 are flush. This structural arrangement makes the integrated component easier to clean and easier to demold during production.
[0030] Furthermore, the one-way valve 52 is a duckbill valve. Through the above structural design, the duckbill valve, with its elastic material properties and mechanical-free design, possesses excellent sealing performance, anti-clogging capabilities, and low maintenance.
[0031] Furthermore, the flow channel support 4 is configured as a 7-shaped structure consisting of a horizontal portion 43 and an inclined portion 44. A liquid channel 45 is formed inside the flow channel support 4. The liquid inlet 41 is located at the free end of the horizontal portion 43, and the liquid outlet 42 is located at the bottom of the inclined portion 44. The liquid inlet 41 and the liquid outlet 42 communicate with the liquid channel 45. More specifically, the inclined portion 44 is located in the lower middle position inside the milk bowl 1. The horizontal portion 43 is cylindrical, and the inclined portion 44 is flat, designed to facilitate connection with the cover plate. This structural configuration facilitates the placement of the flow channel support 4 inside the milk bowl 1.
[0032] Furthermore, the upper end of the milk bowl 1 is provided with a milk inlet 12, which is connected to the milk storage chamber 3. Through the above structural arrangement, during the milk expression process, the milk inlet 12 connects the milk storage chamber 3 with the outside, ensuring that breast milk can flow into the milk storage chamber 3 from the one-way valve 52. After the milk expression is completed, the breast milk can also be poured out and transferred through the milk inlet 12.
[0033] Furthermore, the breast adapter 2 is configured in a trumpet shape, with the liquid inlet 21 located at the smaller diameter end of the trumpet shape. This structural design allows the breast adapter 2 to fit the breast more closely.
[0034] Furthermore, the edge of the breast adapter 2 is detachably fastened to the edge of the milk bowl 1. This structural design facilitates self-disassembly and assembly of this invention by the consumer.
[0035] How to use this utility model:
[0036] During assembly, the first step is to install the integrated component 5 on the support frame 11. The second step is to connect the liquid outlet 42 of the integrated component 5 with the side of the integrated component 5 away from the support frame 11. The third step is to connect the liquid guide port 21 of the breast adapter 2 with the liquid outlet 42 of the integrated component 5. The edge of the breast adapter 2 is fastened to the edge of the milk bowl 1.
[0037] During breastfeeding, the first step is to connect the gas pipe of the negative pressure generating device to the connection hole 61; the second step is for the user to place their breast against the trumpet-shaped breast adapter 2 with the milk outlet 12 facing upwards; the third step is to turn on the negative pressure generating device, which draws air to create negative pressure inside the air pressure chamber 6, causing the negative pressure conductor 51 to deform, the one-way valve 52 to close, and the liquid channel 45 to generate negative pressure due to the increased space. Breast milk is squeezed out by the negative pressure and flows into the liquid channel 45. The negative pressure generating device stops drawing air, the gas chamber is connected to atmospheric pressure, the negative pressure conductor 51 automatically springs back to its original shape, the liquid channel 45 returns to its original volume, the one-way valve 52 opens, and breast milk flows into the storage chamber. The breastfeeding process is completed by repeatedly drawing and releasing air using the negative pressure generating device.
[0038] When pouring milk, tilt this invention to allow the breast milk to flow out from the milk pouring port 12.
[0039] During cleaning, the milk bowl 1, breast adapter 2, flow channel support 4, and integrated component 5 can be separated and cleaned one by one.
[0040] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
