The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0025] Embodiment 1:

[0026] As a first aspect of the present invention, a sucking assembly is provided, which is applied to a milk bottle and needs to be installed at the mouth of the bottle body when in use. Figure 1-4 As shown, the sucking assembly includes a screw cap 100 and a nipple 200. The screw cap 100 has a hole in the middle and is sleeved outside the nipple 200. The nipple is fixed to the bottle mouth through a threaded connection between the screw cap and the bottle mouth.

[0027] The nipple 200 is made of latex or silicone material, has a certain degree of flexibility, and can be deformed. The nipple 200 is a thin-walled structure, including a main body 210 and a connecting end 220 arranged on the main body 210. The screw cap 100 is sleeved on the outside of the connecting end 220, covering the connecting end 220, so that the main body 210 is exposed on the screw cap, and a gap 310 is provided at the junction between the main body 210 and the screw cap 100, and the entrance of the gap 310 is exposed, and external air can enter the gap from the entrance. The connecting end 220 is formed with a receiving hole on the part located inside the screw cap 100, and the receiving hole is connected to the gap 310. A one-way air intake valve 300 is arranged in the receiving hole, and the one-way air intake valve 300 allows gas to enter the inner side of the screw cap 100 from the entrance of the gap 310.

[0028] In some embodiments, the one-way air inlet valve 300 is integrally arranged with the connecting end 220, and the one-way air inlet valve 300 and the nipple 200 are integrally formed with the same material. The one-way air inlet valve 300 adopts a flat duckbill structure, which is two elastic sheets arranged obliquely. The elastic sheet is arranged in the receiving hole and the two sides of the elastic sheet are respectively integrally formed with the hole wall of the receiving hole, and the lower ends of the two elastic sheets are in contact with each other. When the pressure in the bottle cavity is lower than the external air pressure, the external gas can enter through the entrance of the gap 310, then enter the receiving cavity and squeeze the elastic sheet, so that the lower end of the elastic sheet is deformed to form a gap, and finally enter the bottle cavity from the gap, so that the air pressure in the bottle cavity is always the same as that outside, forming a dynamic balance, which is convenient for the baby to continue to absorb water or milk.

[0029] Through the hidden design, the one-way air inlet valve 300 is set in the gap 310 between the rotary cover 100 and the main body 210 of the nipple 200, which cleverly hides the one-way air inlet valve 300, improves the overall aesthetics, is easy to clean, and greatly improves the feeding experience. Compared with the traditional solution in which the one-way air inlet valve 300 is exposed on the nipple 200, the nipple 200 of this embodiment can prevent the user from accidentally blocking the air intake of the one-way air inlet valve 300 during use, and also avoids various non-touch situations in which the one-way air inlet valve 300 is blocked.

[0030] like Figure 2-4 As shown, the shape of the main body 210 of the pacifier 200 imitates the design of the breast, including a simulation part 211 and a sucking part 212. The simulation part 211 is roughly hemispherical and exposed on the screw cap 100. The sucking part 212 imitates the design of the nipple and is provided with a plurality of fine holes. When the baby sucks, liquid can be squeezed out of the fine holes. The connecting end 220 and the sucking part 212 are respectively arranged at the two ends of the simulation part 211. The end surface of the simulation part 211 facing the connecting end 220 protrudes outward from the connecting end 220, and the gap 310 is formed between the end surface of the simulation part 211 facing the connecting end 220 and the screw cap 100. Here, the end surface of the simulation part 211 facing the connecting end 220 is the lower end surface of the simulation part 211, and the lower end surface of the simulation part 211 is smoothly connected to the outer surface to improve the aesthetics.

[0031] A groove 320 is formed on the lower end surface of the simulation part 211, one end of the groove 320 extends to the entrance of the gap 310, and the other end of the groove 320 extends to the one-way air inlet valve 300. With such a design, even if the baby accidentally deforms the simulation part 211 during sucking, the gap between the lower end surface of the simulation part 211 and the screw cap 100 becomes smaller, and external gas can still reach the one-way air inlet valve 300 through the groove 320.

[0032] In some embodiments, in order to further improve the air intake effect and stability, the suction assembly includes a plurality of one-way air intake valves 300, which are arranged at intervals along the circumference of the main body 210. Such a design can prevent the situation in which, in certain circumstances, even if one one-way air intake valve 300 is blocked, external air can still enter the bottle cavity through other one-way air intake valves 300. At the same time, multiple one-way air intake valves 300 can also intake air at the same time, and the intake is more uniform and faster.

[0033] like Figure 2 As shown, the screw cap 100 includes a side wall 110 and an inner edge 120 disposed at one end of the side wall 110 and surrounding the side wall 110. The inner side of the side wall is provided with a thread for threaded connection with the bottle body. The inner edge 120 extends radially inward, and the inner edge 120 is disposed around the connecting end 220 and the inner side wall 110 and the connecting end 220 are alternately spaced. At the same time, the upper side surface of the inner edge 120 is opposite to the lower end surface of the simulation part 211, and the gap 310 is formed between the lower end surface of the simulation part 211 and the inner edge 120.

[0034] Specifically, the connecting end 220 is annular, including an inner connecting portion 221 and an outer connecting portion 222. The diameter of the inner connecting portion 221 is smaller than the diameter of the outer connecting portion 222. The inner connecting portion 221 is located on the inner side of the outer connecting portion 222 and extends axially to one side, and the outer connecting portion 222 extends radially outward. The inner edge 120 is arranged around the outside of the inner connecting portion 221 and connected to the upper side of the outer connecting portion 222. The upper end of the inner connecting portion 221 is connected to the lower end surface of the simulation portion 211. The accommodating hole is arranged on the inner side of the outer connecting portion 222 and is partially located on the outer wall of the inner connecting portion 221, or the groove 320 extends from the lower end surface of the simulation portion 211 and passes through the outer wall of the inner connecting portion 221 to reach the accommodating hole; it is also possible to adopt an inner diameter of the inner edge that is larger than the outer diameter of the inner connecting portion, so that the gap is also formed between the inner side wall of the inner edge and the outer wall of the inner connecting portion.

[0035] In order to improve the sealing performance between the nipple 200 and the bottle mouth, and to ensure that the inner edge 120 of the screw cap 100 and the inner connecting portion 221 are always spaced apart, an annular groove 2221 is provided between the inner edge 120 and the outer connecting portion 222, and an annular convex rib 121 matching the annular groove 2221 is provided between the inner edge 120 and the outer connecting portion 222. In this embodiment, the annular convex rib 121 is provided on the lower side of the inner edge 120, and the annular groove 2221 is provided on the upper side of the outer connecting portion 222. It should be noted that the receiving hole is located on the inner side of the annular groove 2221.

[0036] Drainage ribs 2121 are provided on the inner wall of the main body 210, and specifically, the drainage ribs 2121 extend from the sucking part 212 to the simulation part 211. By providing one or more spiral drainage ribs 2121 on the inner wall of the upper part of the nipple 200, the spiral drainage design can play a role of drainage and buffering when drinking milk, adjust the flow rate of milk, and prevent the baby from choking on milk. At the same time, during the process of sucking milk, the drainage ribs 2121 can prevent the nipple 200 from being sucked flat or stuck, avoid the phenomenon of milk being cut off, and make the nipple 200 not blocked, so that the infant can suck more smoothly.

[0037] Optionally, the sucking portion 212 is inclined to one side on the simulation portion, and the inclination angle is Figure 1 Angle B, i.e., the angle between the axis direction of the sucking part and the axis direction of the simulation part, is in the range of 8 to 25 degrees, preferably 13 degrees. The design makes the nipple tilted 13 degrees from the center when it is put into the baby's mouth. The 13-degree upward tilted nipple imitates the design of the mother's breast, and the baby is more willing to get close to it. At the same time, the upward tilted design makes the baby fit the nursing socket more closely when drinking milk, reducing the air sucked into the corners of the mouth to prevent flatulence.

[0038] In a second aspect, this embodiment further provides a feeding bottle, such as Figure 1 As shown, the feeding bottle comprises a bottle body and the sucking assembly as described in the first aspect, the bottle body is provided with a nipple opening, and the screw cap 100 is detachably connected to the bottle body and closes the nipple opening.

[0039] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention shall be included in the scope of the claims.
