Description

Technical Field

[0001] This utility model relates to the field of maternal and infant products, specifically a sucking-type horn cover assembly and a breast pump. Background Technology

[0002] With the fast pace of modern life and increasing work pressure, more and more mothers are choosing to use breast pumps to help them find a balance between work and childcare. Breast pumps not only effectively solve problems such as insufficient milk supply or blocked milk ducts that may occur during breastfeeding, but also allow mothers to continue providing breast milk to their babies even when it is inconvenient to breastfeed directly. Furthermore, the use of breast pumps provides mothers with greater flexibility, enabling them to better manage their time and balance work and family life.

[0003] Existing breast pumps typically use a funnel-shaped breast shield with a sealed shell at the end furthest from the breast. The sealed shell and the end of the breast shield together form an air pressure chamber. However, because the air pressure chamber is located close to the end of the breast shield, the effective deformation area of ​​the breast shield is far from the breast, making it difficult to fully massage and stimulate breast tissue, which seriously affects the efficiency of the breast pumping process and the user's comfort.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] To address the above problems, this utility model proposes a sucking-type horn-shaped cover assembly and a breast pump, and the technical solution adopted is as follows:

[0006] A suction-type horn cover assembly includes a horn cover assembly comprising a horn cover and a sealing bracket for assembling the horn cover. The horn cover includes a fitting portion for conforming to the breast and a deformable portion connected to the fitting portion. An air pressure cavity is formed between the outer wall of the horn cover and the sealing bracket. The air pressure cavity is located near the opening of the horn cover. When the air pressure cavity is connected to an external vacuum device to form a negative pressure space, the deformable portion undergoes elastic deformation.

[0007] Furthermore, the fitting part is provided with a squeezing part for squeezing the breast, and the squeezing part is arranged along the circumferential direction of the horn cover.

[0008] Furthermore, the extrusion section includes a first extrusion surface and a second extrusion surface, which are inclinedly connected to form a rounded corner.

[0009] Furthermore, an extrusion groove is provided between the first extrusion surface and the second extrusion surface to provide deformation space.

[0010] Furthermore, the horn cover includes a sealing portion connected to the deformable portion and located on the side of the deformable portion away from the fitting portion, and the air pressure chamber includes a first air pressure chamber located between the deformable portion and the sealing bracket, and a second air pressure chamber located within the sealing portion and communicating with the first air pressure chamber.

[0011] Furthermore, the deformable part is provided with a reinforcing rib extending toward the sealing part, and the reinforcing rib is provided with a guide part to guide the airflow in the first pressure chamber toward the second pressure chamber.

[0012] Furthermore, the flow guide includes a flow guide groove located at one end of the reinforcing rib near the second air pressure chamber, and a flow guide surface located on the flow guide groove and extending obliquely toward the second air pressure chamber.

[0013] Furthermore, the reinforcing ribs are spaced apart along the circumferential direction of the deformed portion, and a deformation groove is provided between adjacent reinforcing ribs.

[0014] Furthermore, the deformation groove is provided with a deformation protrusion, which extends obliquely from the deformation part toward the sealing part.

[0015] This utility model also provides a breast pump, including a vacuum device, a milk storage container, and a sucking-type horn cover assembly as described above.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model sets up a horn cover and a sealing bracket. The outer wall of the horn cover and the sealing bracket enclose a pressure chamber. The pressure chamber is located near the opening of the horn cover. When the vacuum device acts on the pressure chamber, the pressure chamber forms a negative pressure space. At this time, the deformable part can undergo elastic deformation. The horn cover can directly fit the breast tissue to achieve better deformation and massage effect, which helps to reduce the discomfort during breast pumping and improves the efficiency of breast pumping.

[0018] 2. The air pressure chamber is positioned close to the opening of the flared shield so that the area of ​​the flared shield that deforms during breastfeeding can directly conform to the breast tissue, which helps to simulate the sucking action of an infant, enhances the massage effect, and stimulates milk secretion.

[0035] Example 1:

[0036] like Figures 1 to 12 The illustration shows a suction-type horn cover assembly, including a horn cover assembly 1. The horn cover assembly 1 includes a horn cover 2 and a sealing bracket 3 for assembling the horn cover 2. The horn cover 2 includes a fitting part 21 for conforming to the breast and a deformable part 22 connected to the fitting part 21. An air pressure cavity 4 is formed between the outer wall of the horn cover 2 and the sealing bracket 3. The air pressure cavity 4 is located near the opening of the horn cover 2. When the air pressure cavity 4 is connected to an external vacuum device to form a negative pressure space, the deformable part 22 undergoes elastic deformation.

[0037] This invention features a horn cover and a sealing bracket. The outer wall of the horn cover and the sealing bracket enclose a pressure chamber, which is located near the opening of the horn cover. When a vacuum device is applied to the pressure chamber, a negative pressure space is created. At this time, the deformable part can undergo elastic deformation, allowing the horn cover to directly conform to the breast tissue, achieving better deformation and massage effects. This helps reduce discomfort during breast pumping and improves breast pumping efficiency.

[0038] Furthermore, the air pressure chamber 4 is positioned close to the opening of the horn cover 2 so that the area of ​​the horn cover 2 that deforms during breastfeeding can directly conform to the breast tissue, which helps to simulate the sucking action of an infant, enhances the massage effect, and stimulates milk secretion.

[0039] Optionally, in some embodiments, the vacuuming device 51 is an airbag-type vacuuming device, which includes an inflatable airbag connected to the air pressure chamber 4. The airbag is inflated and deflated manually or electrically to generate negative pressure.

[0040] Furthermore, as a preferred embodiment of this utility model, the vacuum device 51 is an electric air pump, which is connected to the air pressure chamber 4 and powered by a power source. The electric air pump generates negative pressure during normal operation.

[0041] Optionally, in some embodiments, the vacuum pumping device 51 is directly connected to the pressure chamber 4 via a pipe.

[0042] Furthermore, as a preferred embodiment of this utility model, a front shell is connected to one side of the sealing bracket 3, and a front shell suction channel communicating with the air pressure chamber 4 is provided inside the front shell. An electric air pump communicating with the front shell suction channel is provided on one side of the front shell.

[0043] Furthermore, such as Figures 1 to 12 The fitting part 21 shown is provided with a squeezing part 211 for squeezing the breast, and the squeezing part 211 is arranged along the circumferential direction of the horn cover 2.

[0044] Specifically, the compression part 211 is designed to effectively compress and massage the breast during breast pumping, which helps stimulate the mammary glands and effectively promotes milk secretion and flow. In addition, the compression part 211 is designed to distribute pressure more evenly across the breast, which helps reduce local pressure concentration and improves the comfort of the breast pumping process.

[0045] Furthermore, the compression portion 211 is evenly distributed in the circumferential direction of the horn cover 2, which helps to ensure that the compression force is evenly distributed on the entire contact surface with the breast tissue, thereby providing a circumferential pressure and increasing the tightness and comfort of the fit.

[0046] Furthermore, such as Figures 1 to 12 The extrusion section 211 shown includes a first extrusion surface 2111 and a second extrusion surface 2112, which are inclinedly connected to form a rounded corner.

[0047] Specifically, the cross-section of the squeezing part 211 is "C" shaped, that is, the first squeezing surface 2111 and the second squeezing surface 2112 are connected at an incline to form a rounded corner. The rounded corner is designed to reduce the discomfort caused by sharp angles or right angles when the squeezing part 211 contacts the breast, which helps to improve the overall comfort of the user and make the breast pumping process smoother and more pleasant. Secondly, the rounded corner is designed to allow the squeezing part 211 to better adapt to the natural shape and contour of the breast tissue, which not only helps to more effectively stimulate the mammary glands and promote the flow of milk, but also reduces gaps or discomfort during use.

[0048] Furthermore, such as Figures 1 to 12 An extrusion groove 2113 is provided between the first extrusion surface 2111 and the second extrusion surface 2112 to provide deformation space.

[0049] Specifically, the compression groove 2113 provides additional deformation space for the first compression surface 2111 and the second compression surface 2112 when subjected to external force, so that the compression part 211 can better adapt to the shape and contour of the breast tissue and ensure close contact with the breast during the milk suction process; secondly, by setting the compression groove 2113, the compression part 211 is more flexible when deforming, thereby more effectively squeezing the breast tissue, promoting the flow of milk, helping to enhance the suction effect, and improving the efficiency and comfort of milk suction.

[0050] Optionally, the extrusion groove 2113 is a deformable groove that extends along the circumference of the horn cover 2 and has a cross-section in the shape of an "I".

[0051] Optionally, the extrusion groove 2113 is a deformable groove that extends in the axial direction of the horn cover 2 and has a cross-section in the shape of an "I".

[0052] Optionally, the extrusion groove 2113 is a deformation groove with a wavy cross-section.

[0053] Furthermore, such as Figures 1 to 12 The speaker cover 2 shown includes a sealing part 23 connected to the deformable part 22 and located on the side of the deformable part 22 away from the fitting part 21. The air pressure chamber 4 includes a first air pressure chamber 41 located between the deformable part 22 and the sealing bracket 3, and a second air pressure chamber 42 located in the sealing part 23 and communicating with the first air pressure chamber 41.

[0054] Specifically, the sealing part 23 helps to ensure a good seal between the horn cover and the sealing bracket 3, prevents air pressure leakage, and improves the overall sealing performance and stability.

[0055] Furthermore, the horn cover 2 is mounted on the sealing bracket 3. The outer wall of the horn cover 2 is provided with a first connecting protrusion, and the end of the sealing bracket 3 near the fitting part 21 is provided with a first connecting groove. The first connecting protrusion and the first connecting groove are interference-fitted. The outer wall of the sealing part 23 on the horn cover 2 is interference-fitted with the inner wall of the sealing bracket 3. In addition, the side of the sealing bracket 3 near the sealing part 23 is provided with a second mounting protrusion, and the sealing part 23 is provided with a second mounting groove. The second mounting protrusion and the second mounting groove are snap-fitted together, so that the user can accurately install the horn cover 2 onto the sealing bracket 3. The interference fit between the first connecting protrusion and the first connecting groove, as well as the interference fit between the outer wall of the sealing part 23 and the inner wall of the sealing bracket 3, helps to enhance the overall sealing performance of the device and prevent air leakage. Secondly, the snap-fit ​​connection between the second mounting groove and the second mounting protrusion helps to ensure the precise docking of the horn cover 2 and the sealing bracket 3, which helps to improve the assembly accuracy.

[0056] Furthermore, such as Figures 1 to 12The deformable part 22 shown is provided with a reinforcing rib 221 extending toward the sealing part 23. The reinforcing rib 221 is provided with a guide part 2211 that guides the airflow in the first pressure chamber 41 toward the second pressure chamber 42.

[0057] Specifically, the guide section 2211 can precisely guide the airflow to the second pressure chamber 42, which helps to reduce the turbulence of the airflow in the pressure chamber 4 and effectively ensures that the airflow flows smoothly to the second pressure chamber 42, thereby improving the milk suction efficiency. Secondly, by setting the guide section 2211, the path of the airflow in the pressure chamber 4 is clearer, which helps to reduce the turbulence and flow of the airflow, and helps to optimize the airflow connection between the first pressure chamber 41 and the second pressure chamber 42, effectively improving the stability of the airflow.

[0058] Furthermore, the setting of the reinforcing rib 221 helps to form an effective clearance position inside the air pressure chamber 4, making the structure inside the air pressure chamber 4 more compact. At the same time, it avoids the problems of airflow obstruction or uneven pressure distribution caused by an overly complex structure. Through reasonable clearance setting, it helps to ensure smoother airflow in the air pressure chamber 4, thereby improving the efficiency of the entire system. Secondly, the reinforcing rib 221 occupies a certain space in the air pressure chamber 4, which helps to make the air pressure chamber 4 more easily reach the standard negative pressure state, and helps to ensure that the air pressure chamber 4 can quickly reach and maintain the required negative pressure state when needed.

[0059] Optionally, the reinforcing rib 221 is inclined from the deformable part 22 toward the sealing part 23. The reinforcing rib 221 is arc-shaped or wavy. The arc-shaped or wavy reinforcing rib 221 can provide better flexible deformation effect and adapt to different breast shapes. In addition, the arc-shaped or wavy reinforcing rib 221 makes the deformable part 22 more natural when deformed, which is conducive to improving the comfort of use.

[0060] Furthermore, such as Figures 1 to 12 The flow guide 2211 shown includes a flow guide groove 22111 located at one end of the reinforcing rib 221 near the second air pressure chamber 42, and a flow guide surface 22112 located on the flow guide groove 22111 and extending obliquely toward the second air pressure chamber 42.

[0061] Specifically, the reinforcing rib 221 extends along the length of the deformable portion 22, and the guide portion 2211 is a guide groove 22111 located at the end of the reinforcing rib 221. The guide groove 22111 communicates with the second pressure chamber 42, and the guide groove 22111 is provided with a guide surface 22112 inclined towards the second pressure chamber 42, which is beneficial to accurately guide the airflow to the second pressure chamber 42. When the airflow contacts the guide groove 22111, it will flow along the inclined direction of the guide surface 22112, which helps to reduce airflow turbulence and effectively ensure that the airflow flows smoothly to the second pressure chamber 42. In addition, the arrangement of the guide groove 22111 on the reinforcing rib 221 helps to maximize space utilization. The reinforcing rib 221 and the guide groove 22111 can guide the airflow direction while achieving negative pressure and enhance structural support.

[0062] Furthermore, such as Figures 1 to 12 The reinforcing ribs 221 shown are spaced apart along the circumferential direction of the deformable part 22, and a deformation groove 222 is provided between adjacent reinforcing ribs 221.

[0063] Specifically, the deformation groove 222 is provided to make the deformation of the deformation part 22 more uniform under negative pressure, which helps to reduce local stress concentration, enhance the overall deformation capacity of the deformation part 22, and effectively improve the deformation performance of the deformation part 22. Secondly, by forming the deformation groove 222 between adjacent reinforcing ribs 221, the flexibility of the structure can be increased to a certain extent while maintaining the necessary strength and stiffness, so that the structure can better absorb and disperse energy when subjected to external forces, thereby improving its impact resistance and fatigue resistance.

[0064] Furthermore, such as Figures 1 to 12 The deformation groove 222 shown is provided with a deformation protrusion 2221, which extends obliquely from the deformation part 22 toward the sealing part 23.

[0065] Specifically, the deformation protrusion 2221 is designed so that the deformation groove 222 can deform more when under pressure, which helps to enhance the overall deformation effect, allowing the flared cover 2 to better adapt to changes in the shape and size of the breast, thus providing a more personalized user experience. Secondly, the inclined deformation protrusion 2221 can provide additional deformation space, so that the deformation part 22 can respond more flexibly to different pressures and deformation requirements, effectively enhancing the adaptability of the deformation part 22.

[0066] Furthermore, the deformation protrusions 2221 are designed to distribute pressure more evenly on the deformation portion 22, avoiding excessive local pressure and helping to apply pressure evenly throughout the entire deformation range, thereby improving the performance and comfort.

[0067] The implementation method of Example 2 is as follows:

[0068] This utility model also provides, for example Figures 1 to 12 The breast pump shown includes a vacuum device 51, a milk storage container 52, and a sucking-type horn cover assembly as described above.

[0069] Specifically, the breast pump is equipped with a vacuum device 51 that communicates with the air pressure chamber. The vacuum device 51 is an electric air pump and is the core component of the breast pump. The vacuum device 51 is connected to the air pressure chamber 4, which forms a negative pressure space. The deformation part 22 undergoes elastic deformation so that the flared cover can directly fit the breast tissue and simulate the sucking action of an infant, thereby effectively drawing breast milk from the breast.

[0070] Furthermore, the milk storage container 52 allows the breast milk expressed by the breast pump to be stored, making it convenient for users to feed their babies in different situations and at different times. Secondly, the milk storage container 52 ensures the hygiene of the breast milk during storage and transportation, which helps reduce the risk of breast milk contamination.

[0071] The implementation method of Example 3 is as follows:

[0072] The difference between Example 3 and Example 1 is that the cross-section of the reinforcing rib 221 is rectangular, the reinforcing rib 221 is long and extends along the length of the deformed part 22, and the long reinforcing rib 221 can evenly distribute the negative pressure to multiple areas of the deformed part 22, which is beneficial to improving the overall stability and durability.

[0073] The implementation method of Example 4 is as follows:

[0074] The difference between Example 4 and Example 1 is that: the reinforcing rib 221 extends along the length of the deformed part 22 and is elongated, the guide part 2211 is located at the end of the reinforcing rib 221 and close to the second pressure chamber 42, and the guide part 2211 is a convex arc surface extending towards the second pressure chamber 42. The arc surface can more effectively guide the airflow into the second pressure chamber 42. The shape of the arc surface allows the airflow to smoothly turn when it contacts the guide part 2211, which helps to reduce the airflow resistance and eddies, thereby improving the efficiency and stability of the airflow.

[0075] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments.
