Description

Technical Field

[0001] The utility model relates to the technical field of breast shields, specifically a breast shield. Background Art

[0002] When new mothers breastfeed their babies for the first time, it is very easy to have nipple pain and chapping. There are also some mothers with inverted nipples who cannot breastfeed smoothly. A breast shield is a device used to protect the nipples, which can help lactating mothers protect their nipples from harm, relieve breastfeeding pain, and also help babies suck breast milk more easily.

[0003] The existing method of using a breast shield is that the baby sucks the nipple on the breast shield, so that the cavity of the breast shield forms a negative pressure and presses on the mother's breast, thereby squeezing out the milk for the baby to breastfeed. However, the existing nipple is prone to deformation and collapse during the sucking process, and the space inside the nipple is overly squeezed, so that the baby cannot play a sucking role during sucking, resulting in the baby being unable to suck the milk smoothly and crying loudly, which in turn causes tension and uneasiness to the mother, thus affecting the breastfeeding process.

[0004] In view of the above deficiencies, it is necessary to improve the breast shield, which can solve the problems existing in the process of using the breast shield by mothers and babies, and further meet the improvement of the use experience of mothers and babies during breastfeeding.

[0026] The following will describe in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0027] As Figures 1 to 5The breast shield shown includes a cover body 1 and a nozzle assembly 2 connected to the cover body 1. The cover body 1 includes an outer cover body fitting portion 3 that fits against the breast. The outer cover body fitting portion 3 is provided with an outer cover body fitting cavity 30 and a first fitting portion opening 31 for the breast to extend into the outer cover body fitting cavity 30. The nozzle assembly 2 includes a shield 21 and a nozzle portion 22 connected to the shield 21. A buffer zone 4 is provided between the shield 21 and the outer cover body fitting portion 3. The buffer zone 4 is used for the shield 21 and the nozzle portion 22 to swing. The nozzle portion 22 is provided with a nozzle cavity 220 communicating with the outer cover body fitting cavity 30, a liquid outlet 221 communicating with the nozzle cavity 220, and a nozzle portion reinforcing rib 222 located inside the nozzle cavity 220. The nozzle portion reinforcing rib 222 is arc-shaped and is on the side close to the outer cover body fitting cavity 30. By providing the buffer zone, the present utility model enables the nozzle portion and the shield to swing, thereby reducing the excessive extrusion of the outer cover body fitting cavity during the baby's sucking. The nozzle portion reinforcing rib helps to maintain the shape of the nozzle, reducing the situation where the nozzle portion is prone to deformation and collapse, enabling the milk to flow out smoothly and be sucked by the baby, and improving the comfort and user experience during the mother-infant breastfeeding process.

[0028] Further, as a preferred embodiment rather than a limitation of the present utility model, the outer cover body fitting portion can be attached to the outside of the breast. The first fitting portion opening of the outer cover body fitting portion enables the breast to extend into the outer cover body fitting cavity, thereby maintaining good sealing, reducing milk spillage. By using the nozzle cavity communicating with the outer cover body fitting cavity, the derived milk can be conveyed to the liquid outlet, enabling the milk to flow out from the nozzle portion for the baby to suck.

[0029] Specifically, the buffer zone allows the shield and the nozzle portion to have a certain swinging space during the baby's sucking, which helps the nozzle portion to naturally adjust its position with the baby's sucking action, reducing direct pressure. On the one hand, it can prevent the nozzle portion from deforming and collapsing, ensuring the stable and unobstructed sucking channel. At the same time, it also reduces the extrusion of the nozzle portion on the outer cover body fitting portion, effectively reducing the pressure of the outer cover body fitting portion on the nipple.

[0030] Specifically, the nozzle portion reinforcing rib can enhance the structural strength of the nozzle portion, preventing the nozzle portion from deforming and collapsing due to excessive negative pressure during the baby's sucking. The arc shape of the nozzle portion reinforcing rib can better match the arc shape of the nozzle portion. The nozzle portion can maintain its shape and adapt to the baby's oral cavity, improving the comfort of sucking and reducing the baby's crying and the mother's anxiety caused by difficult sucking.

[0031] Optionally, in some embodiments, the breast shield is made of an elastic material, such as medical-grade silicone or rubber, etc. The elastic breast shield can withstand the negative pressure during the baby's sucking and at the same time maintain a certain elasticity to ensure the smooth flow of milk.

[0032] Optionally, in some embodiments, the nipple shield is made in an integrated manner, which can shorten the production process and reduce production costs.

[0033] like Figure 2 and Figure 3 In the nipple shield shown, the nozzle reinforcement rib 222 extends along the inner wall of the nozzle cavity 220 toward the central axis of the nozzle 22, and the space enclosed by the nozzle reinforcement rib 222 is the anti-backflow area 2221. Further, as a preferred embodiment of the utility model but not a limitation, the nozzle reinforcement rib extends along the inner wall of the nozzle cavity toward the central axis of the nozzle, and the nozzle reinforcement rib can effectively support and reinforce the structure of the nozzle cavity, maintain the shape of the nozzle cavity stable, and prevent deformation and collapse caused by excessive negative pressure when the baby sucks.

[0034] Optionally, in some embodiments, in order to increase the stability and strength of the suction nozzle, a plurality of suction nozzle reinforcement ribs may be designed, and the plurality of suction nozzle reinforcement ribs are evenly distributed around the central axis of the suction nozzle cavity.

[0035] On the one hand, the anti-backflow area can reduce the backflow of lotion back to the outer cover body fitting cavity when the baby stops sucking or the suction force weakens, thereby helping the baby to absorb the lotion more effectively. On the other hand, during the sucking process, negative pressure will cause some lotion to flow back, affecting the sucking efficiency and causing discomfort to the baby swallowing air. Therefore, the anti-backflow area not only effectively prevents the backflow of lotion and ensures the continuity of sucking, but also reduces the chance of the baby swallowing air, reducing flatulence and discomfort.

[0036] like Figure 2 , Figure 3 ,and Figure 5 In the nipple shield shown, the backflow prevention area 2221 is a horizontal plane perpendicular to the central axis of the nipple shield, and the maximum inner diameter of the backflow prevention area 22212 is smaller than the maximum inner diameter of the nozzle cavity 220.

[0037] Specifically, when the breast shield is placed on a horizontal plane stably, the backflow prevention zone is a horizontal plane, so that when the baby sucks at any angle, under the action of gravity, the distance from the surrounding side of any backflow prevention zone to the liquid outlet is equal, and it will not cause that when sucking at a certain angle, the amount of anti-backflow lotion between the suction nozzle cavity and the backflow prevention zone will be more, and when sucking at another angle, the amount of anti-backflow lotion between the suction nozzle cavity and the backflow prevention zone will be less, and the backflow prevention zone can ensure that when the baby stops sucking or the suction force weakens, the lotion is not easy to flow back into the outer cover body fitting cavity due to the effect of gravity. In addition, in some embodiments, the breast shield is slightly downwardly contacted with the baby when in use, and the backflow prevention zone can reduce the retention and accumulation of liquid in the outer cover body fitting cavity, and promote the lotion to flow downward to the liquid outlet more smoothly along the inner wall of the suction nozzle cavity, thereby reducing the backflow and the waste of lotion during the sucking process.

[0038] Further, as a preferred embodiment of the present utility model rather than a limitation, when the maximum inner diameter of the anti-backflow area is smaller than the maximum inner diameter of the nozzle cavity, the anti-backflow area can effectively prevent the backflow of the emulsion. When the baby sucks, the emulsion can flow smoothly through the larger outer cover body fitting cavity and the nozzle cavity. When the baby stops sucking, since the inner diameter of the anti-backflow area is smaller, the emulsion is not easily passed through and flows back into the outer cover body fitting cavity.

[0039] Such as Figures 6 to 8 the nipple shield shown, at least one diversion groove 2222 is provided in the anti-backflow area 2221, the diversion groove 2222 penetrates through the nozzle part reinforcing rib 222, and the diversion groove 2222 is respectively communicated with the nozzle cavity 220 and the outer cover body fitting cavity 30. Specifically, the diversion groove penetrating through the nozzle part reinforcing rib can ensure that the emulsion will not be blocked by the nozzle part reinforcing rib during the flowing process, and the emulsion can smoothly flow from the outer cover body fitting cavity to the nozzle cavity, and by accelerating the transfer speed of the emulsion during sucking, the breastfeeding efficiency is improved. Additionally, the diversion groove penetrating through the nozzle part reinforcing rib does not affect the anti-backflow effect of the anti-backflow area. Part of the emulsion in the nozzle cavity will be blocked by the nozzle part reinforcing rib, reducing the backflow of milk.

[0040] Optionally, in some embodiments, two diversion grooves are provided and symmetrically arranged. Such a setting enables the nozzle part to improve the moving speed of the emulsion at any angle when the baby sucks, avoiding the situation that at one angle, the emulsion can pass through the diversion groove and move, while at another angle, the emulsion is blocked by the nozzle part reinforcing rib and cannot smoothly flow into the nozzle cavity.

[0041] Such as Figures 1 to 5 the nipple shield shown, a plurality of wavy arc surfaces are spaced apart on the outer edge of the opening 31 of the first fitting part, and the projection of the opening 31 of the first fitting part is in a petal shape. Further, as a preferred embodiment of the present utility model rather than a limitation, specifically, the opening of the first fitting part is designed in a petal shape. Besides being beautiful, this non-linear edge can better fit the natural contour of the breast. By increasing the contact area with the skin and the gripping force at the edge, the gaps are reduced and the displacement during use is reduced, thereby improving the sealing performance and preventing the leakage of the emulsion. The wavy arc surface can reduce the direct pressure on the skin along the circumferential side, and make the force around the nipple more uniform by dispersing the force points, thereby increasing the comfort of the user.

[0042] Such as Figures 1 to 5The breast shield shown, the shield 21 is trumpet-shaped and its maximum outer diameter is located on the side close to the outer cover body fitting part 3, and the buffer area 4 is located between the inner side of the shield 21 away from the nozzle part 22 and the outer side of the outer cover body fitting part 3 away from the first fitting part opening 31. Further, as a preferred embodiment of the present invention rather than a limitation, the trumpet-shaped design of the shield can ensure that when the baby sucks, the shield can better fit towards the outer cover body fitting part, and provide sufficient support and stability, provide better coverage and support for the wider part of the breast, and ensure the sealing performance during wearing.

[0043] Specifically, when the nozzle part is squeezed towards the outer cover body fitting part, the maximum outer diameter of the shield is squeezed towards the outer cover body fitting part and provides support. The buffer area can effectively prevent the deformation and collapse of the nozzle part caused by the excessive sucking force of the baby. Since there is a certain swinging space between the shield and the nozzle part to cope with various forces and angle changes generated during the baby's sucking, it can further reduce the compression feeling on the breast and improve the comfort of breastfeeding.

[0044] As Figures 2 to 5 The breast shield shown, the cover body 1 further includes an areola fitting part 5 located in the outer cover body fitting cavity 30 and protruding towards the first fitting part opening 31. The areola fitting part 5 is provided with an areola fitting cavity 50 communicating with the nozzle cavity 220 and a second fitting part opening 51 located between the areola fitting cavity 50 and the outer cover body fitting cavity 30. Further, as a preferred embodiment of the present invention rather than a limitation, the protruding design of the areola fitting part helps the milk flow from the breast to the nozzle part, and the streamline transition can reduce the fluid resistance. The areola fitting part can better fit the natural shape of the breast, especially the areola area, provide more precise protection, reduce unnecessary friction and pressure, increase the sealing performance in the areola area, and reduce the leakage of milk around the areola.

[0045] Specifically, an areola fitting cavity communicating with the outer cover body fitting cavity is provided inside the areola fitting part. The milk can pass through the second fitting part opening from the areola part and directly enter the areola fitting cavity, and then flow into the nozzle cavity, ensuring the smooth and efficient movement path of the milk. Due to the close fitting of the areola fitting part, the milk can be sucked into the baby's mouth more quickly, reducing the retention time of the milk in the outer cover body fitting cavity, thereby improving the overall breastfeeding efficiency.

[0046] As Figures 1 to 4The breast shield shown, the outer cover body fitting part 3 is provided with a connecting part 32 connected to the shield 21 and located in the buffer area 4. The connecting part 32 is provided with a connecting cavity 320 located between the areola fitting cavity 50 and the nozzle cavity 220. The inner diameter of the connecting cavity 320 first increases and then decreases from the nozzle cavity 220 towards the areola fitting cavity 50, or the inner diameter of the connecting cavity 320 gradually increases from the nozzle cavity 220 towards the areola fitting cavity 50. Further, as a preferred embodiment of the present invention rather than a limitation, the connecting part not only plays a role in connecting the outer cover body fitting part and the shield, but also plays a role in transition and support in the breast shield structure. The connecting cavity serves as a channel for the milk to flow from the areola fitting cavity to the nozzle cavity. When a negative pressure is formed inside the breast shield, the connecting cavity can provide a certain deformation transition space.

[0047] Optionally, in some embodiments, when the inner diameter of the connecting cavity gradually increases from the nozzle cavity towards the areola fitting cavity and then gradually decreases, such a setting of the connecting cavity can form a structure similar to a funnel. The maximum inner diameter of the connecting cavity forms a fulcrum for the nozzle part to squeeze towards the outer cover body fitting part, ensuring that the outer cover body fitting part will not be overly deformed.

[0048] Optionally, in some embodiments, when the inner diameter of the connecting cavity gradually increases from the nozzle cavity towards the areola fitting cavity, such a setting can ensure that the milk gradually converges into the nozzle cavity during the flow process, reducing the retention of milk in the areola fitting cavity or the connecting cavity, so as to meet the sucking needs of the baby.

[0049] As Figures 1 to 3 The breast shield shown, the outer periphery of the outer cover body fitting part 3 is provided with a guiding part 34 for the nozzle part 22 to deform in the vertical direction. The guiding part 34 is on the side close to the connecting part 32, and there are multiple guiding parts 34 arranged in a ring shape. Further, as a preferred embodiment of the present invention rather than a limitation, on the side of the guiding part close to the connecting part, during the slight movement deformation caused by the baby's sucking or the mother's movement, the nozzle part can deform along the preset vertical direction to adapt to the natural movement of the breast during breastfeeding, so as to maintain a close fit with the breast, effectively preventing the entry of air and the leakage of milk, improving the sealing performance, ensuring that the milk can smoothly flow from the areola fitting cavity to the nozzle cavity, and then be sucked by the baby. The guiding part ensures the comfort of long-term wearing by fine-tuning the fit degree, reducing the situation of nipple pain and nipple abrasion. In addition, the multiple ring-shaped guiding parts are evenly distributed on the outer periphery of the outer cover body fitting part, so as to ensure that the nozzle part can be effectively supported and guided in multiple directions. The ring-shaped design of the guiding part makes the deformation of the nozzle part more uniform and stable, reducing the pressure or discomfort that may be caused by uneven deformation, thereby improving the comfort of the mother and the baby during breastfeeding.

[0050] AsFigures 1 to 5 The breast shield shown, the outer cover body fitting portion 3 is arranged in a trumpet shape, the areola fitting portion 5 is arranged in a trumpet shape, and a deformation gap 35 is provided between the outer side of the opening 51 of the second fitting portion and the inner wall of the outer cover body fitting cavity 30. Further, as a preferred embodiment of the present invention rather than a limitation, the setting of the deformation gap enables the areola fitting portion to have a certain deformation space when fitting the breast, so as to better adapt to areolas of different shapes and sizes, ensuring that the outer cover body fitting portion can closely fit the breast and reducing the overflow of milk. Due to the existence of the deformation gap, when the breast shield forms a negative pressure, the areola fitting portion can more closely fit the breast, thereby enhancing the negative pressure effect and contributing to more efficient collection of milk and improving the collection efficiency.

[0051] Specifically, the trumpet-shaped setting of the outer cover body fitting portion is beneficial for better fitting breasts of different sizes and shapes, ensuring the stability and comfort of the breast shield during fitting. The trumpet-shaped opening allows the breast to be more easily inserted and provides sufficient support and stability during infant sucking. The trumpet-shaped setting of the areola fitting portion also enables it to adapt to breasts of different sizes and shapes, especially the area around the nipple, providing a closer fit, ensuring that the areola part is comfortably wrapped inside, reducing unnecessary friction and discomfort. Since the trumpet shape of the areola fitting portion helps to enclose the area around the nipple, milk leakage during the milk sucking process can be reduced, facilitating the smooth outflow of milk.

[0052] Specifically, the trumpet shape of the areola fitting portion exerts less pressure on the breast, thereby improving the comfort during use. The trumpet-shaped setting of the outer cover body fitting portion can provide a progressive fitting pressure, that is, the pressure around the nipple is lighter and gradually increases towards the periphery, reducing the direct pressure on the breast and increasing the comfort of the breast shield during fitting. At the same time, the streamlined transition can reduce fluid resistance, and the trumpet-shaped structure is also beneficial for guiding the milk to flow smoothly towards the suction nozzle portion, improving the breastfeeding efficiency. Additionally, the trumpet-shaped structure makes it easier to clean the breast shield.

[0053] Such as Figures 2 to 5The breast shield shown has at least one arc-shaped reinforcing rib 36 provided along the inner wall of the outer cover body fitting cavity 30 in the circumferential direction, and the distance between the reinforcing rib 36 and the first fitting part opening 31 is less than or equal to the distance between the first fitting part opening 31 and the second fitting part opening 51. Further, as a preferred embodiment of the present invention rather than a limitation, setting the reinforcing rib on the inner circumferential side of the first fitting part opening can significantly enhance the structural strength and stability of the inner circumferential side of the first fitting part opening. Especially when used for a long time or under the action of a slight external force, it can maintain the sealing performance of the first fitting part opening, help reduce the entry of air, enhance the negative pressure effect, and thus improve the collection efficiency of the milk. The arc-shaped reinforcing rib enclosing along the inner circumferential direction of the first fitting part opening can provide additional elastic space to adapt to the slight changes of the breast during the milk collection process. At the same time, the arc-shaped reinforcing rib can fit the skin more gently when stretching and retracting, further improving the comfort level.

[0054] Specifically, at least one annular reinforcing rib is provided along the inner wall of the outer cover body fitting cavity in the circumferential direction. The setting of the reinforcing rib can increase the structural strength of the outer cover body fitting part, so that it can maintain a stable shape and fitting degree when the baby sucks or the mother moves. When the distance between the reinforcing rib and the first fitting part opening is small, it can ensure that when the breast is placed into the areola fitting part, the outer cover body fitting part can obtain sufficient support, so as to maintain a stable shape and fitting degree. At the same time, when the distance between the reinforcing rib and the first fitting part opening is less than or equal to the distance between the first fitting part opening and the second fitting part opening, the position of the reinforcing rib is relatively close to the bottom of the breast, which helps to better support the breast, reduce the direct pressure on the breast, and prevent excessive deformation or displacement during breastfeeding.

[0055] Moreover, at least one annular reinforcing rib is arranged along the inner wall of the outer cover body fitting cavity in the circumferential direction, effectively enhancing the anti-deformation ability during sucking, especially against the lateral force generated by the baby's sucking, preventing the outer cover body fitting part from deforming or being damaged under long-term use or strong sucking, and extending the service life of the product. Additionally, when the first fitting part opening turns outwards along the reinforcing rib, the reinforcing rib can abut on the horizontal plane, avoiding the second fitting part opening from contacting the horizontal plane, further ensuring the cleanliness and hygiene of the areola fitting part, and preventing bacteria from breeding around the areola fitting part and affecting the health and safety of the baby when sucking the milk.

[0056] As Figures 1 to 5 shown, the implementation manner of Embodiment 1 is as follows:

[0057] The breast shield includes a cover body 1 and a nozzle assembly 2 connected to the cover body 1. The cover body 1 includes an outer cover body fitting portion 3 that fits against the breast. The outer cover body fitting portion 3 is provided with an outer cover body fitting cavity 30 and a first fitting portion opening 31 for the breast to extend into the outer cover body fitting cavity 30. The nozzle assembly 2 includes a shield 21 and a nozzle portion 22 connected to the shield 21. A buffer zone 4 is provided between the shield 21 and the outer cover body fitting portion 3 for the shield 21 and the nozzle portion 22 to swing. The nozzle portion 22 is provided with a nozzle cavity 220 communicating with the outer cover body fitting cavity 30, a liquid outlet 221 communicating with the nozzle cavity 220, and a nozzle portion reinforcing rib 222 inside the nozzle cavity 220. The nozzle portion reinforcing rib 222 is arc-shaped and is on the side close to the outer cover body fitting cavity 30. The breast shield is made of elastic medical-grade silicone material.

[0058] The nozzle portion reinforcing rib 222 extends along the inner wall of the nozzle cavity 220 towards the central axis direction of the nozzle portion 22, and the space enclosed by the nozzle portion reinforcing rib 222 is an anti-backflow area 2221.

[0059] The anti-backflow area 2221 is a horizontal plane perpendicular to the central axis of the breast shield, and the maximum inner diameter of the anti-backflow area 2221 is smaller than the maximum inner diameter of the nozzle cavity 220.

[0060] The outer edge of the first fitting portion opening 31 is provided with a plurality of wavy arc surfaces at intervals, and the projection of the first fitting portion opening 31 is petal-shaped.

[0061] The shield 21 is trumpet-shaped and its maximum outer diameter is on the side close to the outer cover body fitting portion 3. The buffer zone 4 is located between the inner side of the shield 21 far from the nozzle portion 22 and the outer side of the outer cover body fitting portion 3 far from the first fitting portion opening 31.

[0062] The cover body 1 further includes an areola fitting portion 5 located in the outer cover body fitting cavity 30 and protruding towards the first fitting portion opening 31. The areola fitting portion 5 is provided with an areola fitting cavity 50 communicating with the nozzle cavity 220 and a second fitting portion opening 51 located between the areola fitting cavity 50 and the outer cover body fitting cavity 30.

[0063] The outer cover body fitting part 3 is provided with a connecting part 32 connected to the shield 21 and located in the buffer area 4. The connecting part 32 is provided with a connecting cavity 320 located between the areola fitting cavity 50 and the nozzle cavity 220. The inner diameter of the connecting cavity 320 first increases and then decreases from the nozzle cavity 220 towards the areola fitting cavity 50. The setting of the connecting cavity 320 can form a structure similar to a funnel. The maximum inner diameter of the connecting cavity 320 forms a fulcrum for the nozzle part 222 to extrude towards the outer cover body fitting part 3, ensuring that the outer cover body fitting part 3 will not be excessively deformed.

[0064] The outer periphery of the outer cover body fitting part 3 is provided with a guiding part 34 for the nozzle part 22 to deform in the vertical direction. The guiding part 34 is on the side close to the connecting part 32. There are three guiding parts 34 and they are arranged in a ring shape. The ring diameters of the multiple guiding parts 34 are different and form a stepped shape.

[0065] The outer cover body fitting part 3 is arranged in a trumpet shape, the areola fitting part 5 is arranged in a trumpet shape, and there is a deformation gap 35 between the outer side of the second fitting part opening 51 and the inner wall of the outer cover body fitting cavity 30.

[0066] The inner wall of the outer cover body fitting cavity 30 is provided with a ring-shaped reinforcing rib 36 arranged in a ring shape along the circumferential direction. The distance between the reinforcing rib 36 and the first fitting part opening 31 is less than the distance between the first fitting part opening 31 and the second fitting part opening 51.

[0067] When the baby sucks, negative pressure causes the milk to flow from the breast through the outer cover body fitting cavity 30 into the nozzle cavity 220 and be sucked by the baby through the liquid outlet. When the baby stops sucking or the suction weakens, the structure of the anti-backflow area 2221 can reduce the backflow of the milk back into the outer cover body fitting cavity 30, thereby improving the breastfeeding efficiency.

[0068] By setting the buffer area 4 in the present utility model, the nozzle part 22 and the shield 21 can swing, thereby reducing the excessive extrusion of the outer cover body fitting cavity 30 when the baby sucks. The nozzle reinforcing rib 222 helps to maintain the shape of the nozzle and reduce the situation where the nozzle part is easily deformed and collapses, enabling the milk to flow out smoothly and be sucked by the baby, and improving the comfort and usage experience during the mother-baby breastfeeding process.

[0069] As Figures 6 to 8 shown, the implementation manner of Embodiment 2 is as follows:

[0070] The difference between Embodiment 2 and Embodiment 1 is that two symmetrically arranged diversion channels 2222 are provided in the anti-backflow area 2221. The diversion channels 2222 penetrate through the nozzle part reinforcing rib 222, and the diversion channels 2222 are respectively communicated with the nozzle cavity 220 and the outer cover body fitting cavity 30. There are two nozzle part reinforcing ribs 222 which are symmetrically arranged, and the two nozzle part reinforcing ribs 222 are respectively in a C shape. When the breast shield is placed stably on a horizontal plane, the two nozzle part reinforcing ribs 222 are on the same horizontal plane. Such a setting enables the speed of milk movement to be increased when the nozzle part 22 is sucked by the baby at any angle, and avoids the situation that at one angle, the milk can move through the diversion channels 2222, while at another angle, the milk is blocked by the nozzle part reinforcing rib 222 and cannot flow smoothly into the nozzle cavity 220.

[0071] The above only further illustrates the technical content of the present invention with embodiments to make it easier for readers to understand, but it does not mean that the implementation modes of the present invention are limited to this. Any technical extension or re-creation made according to the present invention is protected by the present invention. The protection scope of the present invention is subject to the claims.
