Description

Technical Field

[0001] This utility model relates to the field of pacifier technology, specifically to a duckbill-type pacifier. Background Technology

[0002] Pacifiers are widely used when breastfeeding infants. Existing pacifiers usually have a barrier structure at the opening. When no external force is applied, the barrier structure closes the opening to prevent liquid from flowing out. When the infant bites and sucks on the corresponding part of the pacifier during feeding, a part of the pacifier is indented, which in turn causes the barrier structure to open the opening, allowing the liquid to flow into the infant's mouth through the opening. When the nipple material is too hard, if the baby bites and sucks on the nipple in the wrong position, the concave area is not enough to move the barrier structure, making it difficult to open the opening. Furthermore, if the opening position is not set properly, liquid can easily flow directly into the middle of the baby's mouth, causing the baby to choke or suffocate.

[0003] For example, patent document with patent application number 202323127970.1 and publication date of November 29, 2024 discloses an anti-spray and anti-choking nipple, including a nipple body and a sucking part. The sucking part has an opening, and the bottom of the opening is connected to a barrier structure. The barrier structure includes a first elastic barrier and a second elastic barrier. A through hole is provided between the first elastic barrier and the second elastic barrier, and the through hole communicates with the opening. The first elastic barrier and the second elastic barrier abut against each other and close the through hole under their own elastic force. By the mutual abutment of the first elastic barrier and the second elastic barrier, when there is no external force interference, the through hole and the opening are blocked, preventing liquid from flowing out of the opening, which has the effect of preventing leakage and spraying, and has good reliability. When the baby bites the sucking part, it squeezes the barrier structure, the first elastic barrier and the second elastic barrier separate, the through hole is opened, and the liquid flows out through the through hole and the opening.

[0004] The above literature describes an opening in the sucking part. Because there is a barrier structure at the bottom of the opening, the baby needs to bite the sucking part in a specific position to open the opening. If the baby bites in an inaccurate position, the opening may not be able to open and the liquid may not be able to flow out. Even if the baby bites and sucks in a specific position, because the baby is small and has insufficient biting ability, it is not possible to generate enough indentation deformation to move the barrier structure, thus failing to open the opening. Summary of the Invention This invention provides a duckbill-style pacifier that makes it easy to suck and release liquid, and is less likely to cause choking.

[0005] To achieve the above objectives, the technical solution of this utility model is: a duckbill-type nipple, comprising a nipple body, wherein the nipple body is provided with a suction head, the suction head is hollow to form a first channel, the suction head is provided with a blocking structure, the blocking structure comprising a first elastic member and a second elastic member, a through hole is provided between the first elastic member and the second elastic member, the through hole is connected to the first channel, the first elastic member and the second elastic member abut against each other and close the through hole under their own elastic force, the blocking structure is provided on the side of the suction head, and two opposing squeezing blocks are respectively provided on both sides of the blocking structure, the squeezing blocks are protruding on the inner or outer side of the suction head, when the squeezing blocks are pressed and brought closer together, the first elastic member and the second elastic member overcome their own elastic force and move away from each other, opening the through hole.

[0006] The above configuration, with a through hole between the first and second elastic members, prevents liquid from flowing out of the through hole if the infant does not bite the mouthpiece. A squeezing block is provided on the inner or outer side of the mouthpiece. When the infant sucks on the corresponding position of the squeezing block, the elastic force of the first and second elastic members is overcome, causing them to move away from each other and opening the through hole, allowing the liquid to flow out of the through hole. Furthermore, the cross-sectional area of ​​the squeezing block is smaller than that of the mouthpiece, so pressing the squeezing block will not block the entire inside of the mouthpiece, allowing the liquid to flow out from the first channel to the outside of the through hole. The squeezing block is designed to amplify the deformation produced when the baby bites the sucking nipple, thus more easily overcoming the self-elastic forces of the first and second elastic elements to open the through hole. Since the squeezing blocks also open the first and second elastic elements when they come closer together, and since the squeezing blocks are located on both sides of the blocking structure and protrude from the inner or outer wall, the sucking heads on both sides of the squeezing blocks will act on the entire blocking structure more quickly when the squeezing blocks come closer together, thereby opening the through hole of the first and second elastic elements of the blocking structure, without needing to apply a large force to the ends of the first and second elastic elements to open the through hole, thus facilitating milk feeding. Compared to the previous situation without the squeezing block, when the baby bites the sucker head, the deformation only occurs at the biting position. When the biting position is far from the blocking structure, the deformation generated by biting is insufficient to overcome the elastic force of the first and second elastic elements to move away from each other and open the through hole.

[0007] Furthermore, two blocking structures are provided, one on each side of the nozzle tip and the other on the inner or outer side of the nozzle tip between the two blocking structures.

[0008] With the above configuration, the squeezing block located between the two blocking structures ensures that the blocking structures on both sides are subjected to relatively balanced forces when the baby bites down. For example, when the baby bites down on the squeezing block, the force is transmitted through the squeezing block to the blocking structures on both sides, allowing the first and second elastic elements to be squeezed more evenly, thereby ensuring that the opening and closing action of the through hole is more stable and reliable.

[0009] Furthermore, the cross-sectional area of ​​the extrusion block is smaller than the cross-sectional area of ​​one side of the suction head on which the extrusion block is located.

[0010] The above settings allow the extrusion block to act more effectively on the nozzle head, and prevent the extrusion block from being too large and thus failing to act effectively on the first and second elastic elements.

[0011] Furthermore, the width of one extrusion block is less than the distance between the two blocking structures.

[0012] With the above configuration, since the width of the squeezing block is less than the distance between the two blocking structures, the squeezing block will not excessively squeeze the blocking structure. The blocking structure can maintain a tighter closed state when there is no external force, thereby effectively preventing liquid from leaking from the through hole.

[0013] Furthermore, the height of the extrusion block near the blocking structure is lower than or equal to the height of the bottom of the blocking structure.

[0014] With the above configuration, when the height of the squeezing block on the side near the blocking structure is equal to or lower than the bottom of the blocking structure, when the baby bites the squeezing block, the force on the squeezing block can be transferred from all sides to the through hole, which can more effectively transmit the force to the blocking structure and can act more directly on the first elastic element and the second elastic element, thus making it easier to overcome the elastic force and open the through hole.

[0015] Furthermore, the nozzle head includes two oppositely arranged first sides and two oppositely arranged second sides and an end face. The two sides of the first side are connected to the two second sides, and the end face is connected to the first side and the second side respectively. The extrusion block is arranged on the first side, and the through hole is arranged on the second side. The area of ​​the first side is larger than the area of ​​the second side.

[0016] The above configuration places the extrusion block on the larger side of the duckbill nipple, which allows the extrusion block to better open the through hole when it is squeezed.

[0017] Furthermore, the two extrusion blocks are located on both sides of the first channel and there is a gap between the two extrusion blocks. The extrusion block located inside the nozzle head protrudes towards the first channel, or the extrusion block located outside the nozzle head protrudes away from the first channel.

[0018] The above configuration leaves a gap between the two squeezing blocks, allowing them to approach each other when the baby bites on them. This overcomes the elasticity of the first and second elastic elements, causing them to move away from each other and open the through hole. Furthermore, the squeezing blocks protrude inward from the inner wall of the mouthpiece or outward from the outer wall, enabling the mouth to make contact with the squeezing blocks more quickly and thus opening the through hole.

[0019] Furthermore, the second side is provided with a stepped surface that is recessed downward and inward, and a through hole is provided on the stepped surface.

[0020] The above settings, by setting a stepped surface, enable the through hole to be closed by both horizontal and vertical action when the extrusion block is not being extruded.

[0021] Furthermore, through holes are located at the intersection of the stepped surfaces.

[0022] With the above design, the through holes are located at the intersection of the stepped surfaces, so that when the liquid flows naturally upward and outward along the inclined through holes, the liquid will flow to both sides of the baby's mouth, preventing the liquid from flowing directly into the middle of the baby's mouth and causing the baby to choke or suffocate.

[0023] Furthermore, the through hole is located on the horizontal surface of the stepped surface.

[0024] With the above configuration, the through hole is set on a horizontal plane and vertically upward along the end of the nozzle. The liquid flows to both sides of the baby's mouth, preventing the liquid from flowing directly into the middle of the baby's mouth and causing the baby to choke or suffocate.

Detailed Implementation

[0034] Example 1.

[0035] like Figure 1-8 As shown, a duckbill-type nipple includes a nipple body 1, a suction head 2, and a first channel formed by the hollow structure of the suction head 2. The suction head 2 is provided with a blocking structure 3, which includes a first elastic element 31 and a second elastic element 32. A through hole 33 is provided between the first elastic element 31 and the second elastic element 32, and the through hole 33 is connected to the first channel. The first elastic element 31 and the second elastic element 32 abut against each other and close the through hole 33 under their own elastic force. The blocking structure 3 is provided on the side of the suction head, and the blocking structure 3 is located on both sides of the end of the suction head 2 or only on one side. Squeezing blocks 5 are respectively provided on both sides of the blocking structure 3. The cross-sectional area of ​​the squeezing blocks 5 is smaller than the cross-sectional area of ​​one side of the suction head 2 where the squeezing blocks are provided. The squeezing blocks 5 protrude from the inner or outer side of the suction head 2. When the squeezing blocks 5 are pressed and brought closer together, the first elastic element 31 and the second elastic element 32 overcome their own elastic force and move away from each other, opening the through hole 33.

[0036] like Figure 3-6 As shown, the squeezing block 5 is located inside the suction head 2 and between the two blocking structures 3. When the baby bites, the squeezing block 5 between the two blocking structures 3 can ensure that the blocking structures 3 on both sides are subjected to relatively balanced forces simultaneously. For example, when the baby bites the squeezing block 5 with their teeth, the force is transmitted to the blocking structures 3 on both sides through the squeezing block 5, so that the first elastic member 31 and the second elastic member 32 can be squeezed relatively evenly, thereby ensuring that the opening and closing action of the through hole 33 is more stable and reliable.

[0037] The width of one squeezing block 5 is less than the distance between the two blocking structures 3. Because the width of one squeezing block 5 is less than the distance between the two blocking structures 3, the squeezing block 5 will not excessively squeeze the blocking structure 3. The blocking structure 3 can maintain a tighter closed state when there is no external force, thereby effectively preventing liquid from leaking from the through hole 33.

[0038] The height of the squeezing block 5 is equal to or lower than the height of the bottom of the blocking structure 3. When the squeezing block 5 is close to the side of the blocking structure 3, its height is equal to or lower than the bottom of the blocking structure 3. When the baby bites the squeezing block 5, the squeezing block 5 can more effectively transmit force to the blocking structure 3 and can act more directly on the first elastic member 31 and the second elastic member 32, thus making it easier to overcome the elastic force and open the through hole 33.

[0039] The two squeezing blocks 5 are located on both sides of the first channel and there is a gap between the two squeezing blocks 5. The squeezing block 5 located on the inner side of the suction head protrudes in the direction of the first channel, or the squeezing block 5 located on the outer side of the suction head protrudes in the direction away from the first channel, so that when the baby bites the squeezing block 5, the two squeezing blocks 5 can approach each other, thereby overcoming the elastic force of the first elastic member 31 and the second elastic member 32 to move away from each other and open the through hole 33.

[0040] like Figure 5 As shown, the suction head 2 includes two oppositely arranged first side surfaces 20 and two oppositely arranged second side surfaces 21 and an end face 22. The two sides of the first side surface 20 are connected to the two second side surfaces 21, and the end face 22 is connected to the first side surface 20 and the second side surface 21 respectively. The extrusion block 5 is disposed on the first side surface 20, and the through hole is disposed on the second side surface 21. The area of ​​the first side surface 20 is larger than the area of ​​the second side surface 21.

[0041] like Figure 6 As shown, the second side surface 21 is provided with a downwardly and inwardly recessed stepped surface 211, and a through hole is provided at the intersection of the stepped surface 211. The through hole 33 is inclined upward and outward along the end of the suction head 2. In embodiment one, the direction of the through hole 4 is as follows. Figure 3 As shown, when the liquid flows out naturally along the inclined through-hole 33, the liquid will flow to both sides of the baby's mouth, preventing the liquid from flowing directly into the middle of the baby's mouth and causing the baby to choke or suffocate.

[0042] In this embodiment, the first elastic element and the second elastic element are integrally formed, the first elastic element is the vertical surface of the step surface, and the second elastic element is the horizontal surface of the step surface.

[0043] The working principle of this utility model is as follows: A through hole 33 is provided between the first elastic member 31 and the second elastic member 32. If the baby does not bite the mouthpiece 2, the liquid will not flow out from the through hole 33. A squeezing block 5 is provided inside the mouthpiece 2. When the baby squeezes the squeezing block 5 at the corresponding position, the elastic force of the first elastic member 31 and the second elastic member 32 is overcome and they move away from each other, thereby opening the through hole 33 and allowing the liquid to flow out from the through hole 33. The cross-sectional area of ​​the squeezing block 5 is smaller than that of the mouthpiece 2. When the squeezing block 5 is pressed, it will not block the entire inside of the mouthpiece 2, thus allowing the liquid to flow out from the first channel to the outside of the through hole 33. The squeezing block 5 is designed to expand the deformation generated when the baby bites the sucking head 2, so as to more easily overcome the mutual elasticity of the first elastic element 31 and the second elastic element 32 and open the through hole 33. That is, when the baby bites the squeezing block 5 away from the blocking structure 3, the side away from the blocking structure 3 is displaced, which in turn can drive the entire squeezing block 5 to be displaced. When the entire squeezing block 5 is displaced, the through hole 33 can be opened better.

[0044] Example 2.

[0045] As shown in Figure 7, the only difference between this second embodiment and the first embodiment is that the extrusion block 5 is located on the outside of the nozzle head 2.

[0046] Example 3.

[0047] As shown in Figure 8, the only difference between this embodiment three and embodiment one is that the through hole 33 is set on the horizontal surface of the step surface, and the through hole 33 is set vertically upward along the end of the suction head 2. The direction of the through hole 6 in embodiment three is as follows: Figure 8 As shown, since the blocking structure 3 is located on both sides of the end of the mouthpiece 2, that is, the through hole 33 is located on both sides of the end of the mouthpiece 2, and the through hole 33 is set vertically upward along the end of the mouthpiece 2, the liquid flows to both sides of the baby's mouth, preventing the liquid from flowing directly to the middle of the baby's mouth, which could cause the baby to choke or suffocate.
