[0031] Embodiment 1

[0032] like Figure 1-6 As shown, the nipple assembly of this embodiment includes a nipple 1, a straw 2 and a flow valve 24. The nipple 1 includes a nipple body 11 and a sucking head 12, and the sucking head 12 has a first channel 121. The straw 2 has a second channel 25, the straw 2 is connected to the nipple body 11, and the second channel 25 of the straw 2 is connected to the first channel 121 of the sucking head 12.

[0033] The flow valve 24 is arranged in the second channel 25 of the straw 2, and includes two control sheets 241. The two control sheets 241 are arranged opposite to each other and connected to the straw 2. A sealing surface 243a is provided on the opposite surfaces of the two control sheets 241. In a natural state without sucking, the sealing surfaces 243a of the two control sheets 241 fit tightly to prevent liquid from flowing into the first channel 121 through the second channel 25. When sucking is performed, the sealing surfaces 243a of the two control sheets 241 are pushed open, thereby allowing liquid to flow into the first channel 121 through the second channel 25.

[0034] The straw of the above-mentioned pacifier assembly has a flow valve 24 disposed inside the straw 2, which effectively avoids the position where lips suck, and the flow valve 24 will not be deformed or bitten, thereby extending the service life; moreover, the feeling of mouth fatigue caused by the rebound force of the flow valve 24 during sucking is avoided.

[0035] like Figure 4 As shown, in one embodiment, the control sheet 241 includes a support portion 242 and a sealing portion 243. The support portions 242 of the two control sheets 241 are symmetrically fixed in the straw 2, and the sealing portions 243 of the two control sheets 241 are respectively arranged at the opposite ends of the two support portions 242. The sealing surface 243a is arranged on the sealing portion 243 and extends along the axial direction of the straw 2. The support portion 242 of the control sheet 241 is symmetrically fixed in the straw 2. This symmetrical design helps to maintain the balance and stability of the entire nipple assembly and reduce the degradation of the sealing performance caused by the deformation or displacement of the straw 2. In addition, the sealing surface 243a extends along the axial direction of the straw 2. By changing the size of the sealing surface 243a of the sealing portion 243, the suction force required for the sealing surface 243a to be pushed open can be adjusted.

[0036] In this embodiment, the support portions 242 of the two control sheets 241 are arranged in an eight-shaped shape. With this structure, the control sheet support portions 242 arranged in an eight-shaped shape can more effectively control the flow of the fluid, and by precisely adjusting the fluid channel inside the straw 2, fine control of the fluid flow rate and flow direction can be achieved, which can prevent the baby from choking or inhaling too quickly. Moreover, the support portions 242 arranged in an eight-shaped shape can form a tighter structural fit inside the straw 2, and combined with the sealing portion 243, can effectively improve the sealing performance of the entire system, prevent liquid leakage, and ensure hygiene and safety during use.

[0037] In one embodiment, each control sheet 241 may further include a guide portion 244, which is located at the other end of the sealing portion 243 opposite to the support portion 242. With this design, by adding the guide portion 244 to the control sheet 241, the liquid can be more effectively guided to flow along a predetermined path. This diversion effect helps to evenly distribute the liquid, ensuring that the liquid can flow out smoothly and continuously during sucking, thereby improving the user experience. Moreover, the provision of the guide portion 244 can reduce the resistance of the liquid during the sucking process, so that the user needs less force when sucking, thereby improving the sucking efficiency. In addition, the guide portion 244 can ensure the smooth flow of the liquid, avoid choking caused by sucking too fast, and thus improve the safety of feeding.

[0038] In one embodiment, a slope 243b is provided on each of the opposite surfaces of the sealing portion 243, and the slopes 243b are located on the side of the sealing surface 243a close to the sucking head and form a "V" shape. This design optimizes fluid dynamics, allowing liquid to pass through the control sheet more smoothly, thereby reducing flow resistance.

[0039] In one embodiment, the flow valve 24 is located on the side of the second channel 25 close to the sucking head 12, so that the amount of liquid flowing out through the sucking head 12 can be more accurately controlled, and the flow rate can be adjusted according to the sucking strength of the baby to avoid choking. Preferably, the second channel 25 includes a first through hole 251 with a larger diameter close to the sucking head 12 and a second through hole 252 with a smaller diameter away from the sucking head 12, and the flow valve 24 is arranged in the first through hole 251. By setting the flow valve 24 in the first through hole 251 with a larger diameter, the amount of liquid flowing through the sucking head 12 can be more effectively controlled. The first through hole 251 provides sufficient space for the flow valve 24, so that it can adjust the flow rate more flexibly, whether increasing or decreasing the flow rate, it can be achieved more accurately. In addition, it is convenient to process and form the flow valve 24.

[0040] In this embodiment, the nipple 1 also includes a mounting portion 13 located in the nipple body 11, and the mounting portion 13 includes an annular convex portion 131. The straw 2 includes a straw body 21 and a connector 22, which is made of a hard material (such as silicone, plastic or metal with a hardness of more than 50 degrees), and its lower part is connected to the upper end of the straw body 21, and the upper part is provided with a connecting portion, and the connecting portion is provided with an annular slot 223, so as to achieve connection through the mutual insertion of the convex portion 131 and the slot 223. A first through hole 251 is provided in the center of the connector 22, and the flow valve 24 is arranged in the first through hole 251 of the connector 22. The nipple 1 and the straw 2 of the straw of the nipple assembly are connected by the mutual insertion of the convex portion 131 and the slot 223. This design realizes a stable connection between the straw 2 and the nipple 1, and is also easy to disassemble and clean. Moreover, the connector 22 is made of a hard material to prevent the elastic silicone rubber nipple from being deformed and loosened.

[0041] In one embodiment, the connector 22 includes a middle portion 221 protruding upward in the axial direction and an outer sleeve portion 222 surrounding the outer side of the middle portion 221, and a slot 223 is formed between the outer sleeve portion 222 and the middle portion 221; the inner diameter of the protrusion 131 is equal to or smaller than the outer diameter of the middle portion 221, and the outer diameter of the protrusion 131 is equal to or larger than the outer diameter of the outer sleeve portion 222. This design further enhances the stability of the connection.

[0042] In one embodiment, the straw 2 further includes a gravity ball 23, which is connected to the lower end of the straw body 21. The gravity ball 23 ensures that the lower end of the straw can sink into the liquid regardless of the tilt angle of the bottle, thereby ensuring that the baby can smoothly absorb milk in various postures.

[0043] During production, the flow valve 24 and the connecting head 22 are integrally formed, and then integrally formed with the straw body 21 and the gravity ball 23 by injection molding.

[0044] Embodiment 2

[0045] like Figure 7 As shown, the structure of the straw of the nipple assembly in this embodiment is substantially the same as that of the embodiment, except that the support portion 242 of the control sheet 241 is arranged in a "V" shape, and the upper surface 242a of the support portion 242 is connected to the sealing surface 243a. With this design, through the "V"-shaped layout, the fluid may experience a smoother flow path when passing through the control sheet, reducing the resistance and turbulence when the liquid flows, thereby improving the efficiency of fluid transmission; moreover, the "V"-shaped support portion may provide a stronger support for the control sheet, reducing vibration or deformation during use, thereby improving the durability and service life of the nipple assembly.

[0046] Embodiment 3

[0047] like Figure 8 As shown, the structure of the nipple assembly in this embodiment is the same as that in the first embodiment, except that the control sheet 241 omits the flow guide portion, that is, the control sheet 241 in this embodiment includes a support portion 242 and a sealing portion 243, the support portions 242 of the two control sheets 241 are symmetrically fixed in the straw 2, and the sealing portions 243 of the two control sheets 241 are respectively arranged at the opposite ends of the two support portions 242. The flow valve of this structure is simple in structure and easy to form.

[0048] In one embodiment, a feeding bottle is provided, comprising a bottle body and the nipple assembly described in the above embodiment.

[0049] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model.
