Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] The core of the present invention is to provide a nipple that can ensure the ventilation effect. Another core of the present invention is to provide a baby bottle including the above nipple, and its nipple can ensure the ventilation effect.

[0041] It should be noted that when an element is referred to as "fixed" to another element, it can be directly on the other element or there may also be a middle element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be a middle element at the same time. In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0043] In a specific embodiment of the pacifier provided by the present invention, it comprises a pacifier body 1 and a connection cover 2 for connecting the pacifier body 1 to the bottle body 3 of the feeding bottle. The connection cover 2 is an annular structure, and can be threadedly connected and fixed to the bottle body 3 of the feeding bottle.

[0044] like Figure 3 As shown, the nipple body 1 includes a nipple portion 11 and a base portion 12 arranged in sequence along the axial direction. The nipple portion 11 is provided with a suction hole 112, so that the substance inside the bottle body 3 can be sucked out through the suction hole 112. The portion of the nipple body 1 located between the nipple portion 11 and the base portion 12 is sunken inward along the radial direction to form a mounting groove 13. Figure 7 and Figure 12 As shown, an axial end of the connecting cover 2 extends radially inward to form a mounting ring 23, and the mounting ring 23 is inserted into the mounting groove 13. The mounting ring 23 is clamped by the base 12 and the nipple portion 11, so that the nipple body 1 and the connecting cover 2 are snap-fitted and installed together to prevent the nipple body 1 from axially separating from the connecting cover 2.

[0045] Please refer to Figure 7 and Figure 12 A nipple vent hole 111 is axially penetrated near the base 12 on the nipple portion 11, and a one-way valve 14 is provided on the base 12, and the air outlet direction is toward the inside of the connection cover 2. A cover vent hole 21 is axially penetrated on the mounting ring 23. Optionally, the cover vent hole 21 is a straight circular through hole extending in the axial direction. External gas can enter the one-way valve 14 through the nipple vent hole 111 and the cover vent hole 21 in sequence, and then enter the inside of the connection cover 2.

[0046] Since the cover body vent hole 21 is directly opened on the mounting ring 23, instead of forming an axial gap between the nipple body 1 and the connecting cover 2 for ventilation as in the prior art, during use, the ventilation condition of the cover body vent hole 21 will not be affected by the deformation of the nipple body 1, and the ventilation effect can be effectively guaranteed.

[0047] Furthermore, an inner annular cavity 24 coaxial with the nipple body 1 is provided at the axially fitting portion of the mounting ring 23 and the base 12, and the inner annular cavity 24 is connected to the interior of the connection cover 2 through the one-way valve 14, and the inner annular cavity 24 is connected to the cover body vent 21. Specifically, as for the formation of the inner annular cavity 24, Figure 7 , Figure 9 and Figure 12 As shown, an inner annular groove 241 coaxial with the nipple body 1 is provided on the axial end surface of the mounting ring 23 close to the base 12, and the axial end surface of the base 12 close to the mounting ring 23 covers the inner annular groove 241 to form an inner annular cavity 24, and the cover body vent 21 is connected to the inner annular groove 241. Of course, in other embodiments, the inner annular cavity 24 can also be provided by opening a groove on the base 12 and the mounting ring 23 covers the groove.

[0048] For embodiments without the inner annular cavity 24, the cover ventilation hole 21 needs to be axially aligned with the one-way valve 14 to achieve the connection between the two. That is, the outlet of the cover ventilation hole 21 and the inlet of the one-way valve 14 have at least partially overlapping areas in the direction perpendicular to the axis, or have at least partially overlapping areas after axial translation. However, in this embodiment, due to the setting of the inner annular cavity 24, if the cover ventilation hole 21 is not axially aligned with the one-way valve 14, the gas can move circumferentially under the guidance of the inner annular cavity 24 and then enter the one-way valve 14, without requiring the one-way valve 14 to be axially aligned with a cover ventilation hole 21 after assembly, further reducing the processing requirements.

[0049] Furthermore, please refer to Figure 6 、 Figure 7 and Figure 12 , an outer annular groove 25 coaxial with the nipple body 1 is provided on the axial end face of the mounting ring 23 close to the nipple portion 11, and the nipple ventilation hole 111 communicates with the cover ventilation hole 21 through the outer annular groove 25.

[0050] The setting of the cover ventilation hole 21 reduces the assembly requirements for the nipple ventilation hole 111 and the cover ventilation hole 21, so that even if the axis lines of the nipple ventilation hole 111 and the cover ventilation hole 21 are misaligned by a large angle, the gas in the nipple ventilation hole 111 can enter the cover ventilation hole 21 through the circumferential guidance of the outer annular groove 25.

[0051] Furthermore, please refer to Figure 12 , a lateral airway opening 4 is formed between the surface of the nipple portion 11 close to the outer annular groove 25 and the outer annular groove 25, so that external air can enter the outer annular groove 25 through the lateral airway opening 4.

[0052] Through the setting of the lateral airway opening 4, in the Figure 12 shown orientation, the external gas can directly pass from the top nipple ventilation hole 111 to the one-way valve 14, as indicated by the arrow on the solid line with an arrow, or can also lead to the one-way valve 14 from the side through the lateral airway opening 4, as indicated by the arrow on the dashed line with an arrow, realizing dual-channel ventilation, ensuring smooth air circulation and facilitating milk sucking.

[0053] Furthermore, there are at least two cover ventilation holes 21. Preferably, the cover ventilation holes 21 are arranged at equal intervals along the circumference with the axis line of the nipple body 1 as the center. Specifically, as shown in Figure 9 , four cover ventilation holes 21 are provided and arranged at equal intervals along the circumference with the axis line of the nipple body 1 as the center.

[0054] Since there are at least two cover ventilation holes 21, when one of the cover ventilation holes 21 is blocked, the other cover ventilation holes 21 can still be used normally, ensuring the reliability of ventilation.

[0055] Further, please refer to Figure 4 , the one-way valve 14 protrudes from the base 12 axially and away from the nipple portion 11. Figure 4 In this orientation, the one-way valve 14 protrudes downward from the base 12. A valve peripheral groove 121 is formed on the axial end surface of the base 12 away from the nipple portion 11, and the valve peripheral groove 121 is arranged around the outer periphery of the one-way valve 14.

[0056] The one-way valve 14 adopts a protruding design, and at the same time, the periphery is hollowed out to separate the one-way valve 14. While ensuring that the one-way valve 14 can be installed in the connection cover 2 together with the base 12, the connection strength between the one-way valve 14 and the base 12 can be reduced, making the connection between the two relatively weak. When the nipple body 1 is deformed due to sucking or biting, even if the base 12 shakes due to being pulled, such as Figure 4 the part of the base 12 on the left side of the one-way valve 14 shakes in the figure. Due to the isolation effect of the valve peripheral groove 121, the one-way valve 14 can remain unchanged and not be affected, thus preventing the water leakage problem caused by the one-way valve 14 being pulled open by external force.

[0057] Further, please refer to Figure 3 and Figure 5 , ribs 113 are provided on the inner surface of the nipple portion 11, and the ribs 113 extend in a spiral shape centered on the axis of the nipple body 1. Preferably, at least two ribs 113 are arranged on the inner surface of the nipple portion 11 in sequence along the circumferential direction, specifically three. The cooperation of different ribs 113 has a flow splitting effect, which can improve the balance of milk flow and prevent the baby from hiccupping. In addition, the ribs 113 are preferably arranged close to the suction hole 112.

[0058] When the nipple portion 11 is sucked, due to the supporting effect of the ribs 113, the nipple portion 11 will not be completely sucked flat, which affects the outflow of milk. In addition, on the nipple portion 11, the suction hole 112 is formed by penetrating the axial end of the nipple portion 11 along the axis of the nipple body 1. Since the ribs 113 are arranged in a spiral shape, as Figure 5 shown, the ribs 113 generally surround the suction hole 112. When the whole milk bottle is inverted, especially when the milk bottle is suddenly inverted, the milk can flow into the suction hole 112 along the tangential direction of the suction hole 112 under the guidance of the ribs 113, such as Figure 3 the direction indicated by the arrow on the solid line with an arrow in the figure, rather than directly entering the suction hole 112 along the radial direction of the suction hole 112, which can play a certain buffering role and avoid a large amount of milk rushing towards the suction hole 112 quickly when the milk bottle is inverted.

[0059] The nipple provided in this embodiment has a lid vent hole 21 provided on the connecting lid 2, and its on-off state is not affected by external artificial installation or deformation of the nipple caused by a child's biting; after assembling the nipple body 1 to the connecting lid 2, specifically, the nipple vent hole 111 can be axially aligned with one of the lid vent holes 21, and air can enter the one-way valve 14 directly through the nipple vent hole 111. Or, the nipple vent hole 111 may not be axially aligned with any of the lid vent holes 21. With the help of the inner annular cavity 24 and the outer annular groove 25, air can also enter the one-way valve 14 through the nipple vent hole 111, reducing the requirements for the machining accuracy and assembly accuracy of each component and facilitating assembly; after the nipple body 1 is installed into the connecting lid 2, a closed air passage is naturally formed, including a double gas passage formed by the lateral airway opening 4 and the nipple vent hole 111. If one airway is blocked, the other airway can still intake air; the spiral rib 113 makes a circulating flow channel formed inside the nipple portion 11, which can play a buffering role during backflow.

[0060] Obviously, in other embodiments, the nipple portion 11 can also cover the outer annular groove 25, that is, the lateral airway opening 4 is not provided, so that external gas can only enter the outer annular groove 25 through the nipple vent hole 111.

[0061] In addition to the above nipple, the present invention also provides a baby bottle, which includes a nipple, specifically, it can be the nipple provided in any of the above embodiments, and the beneficial effects can be referred to the above respective embodiments accordingly. Specifically, the baby bottle further includes a bottle body 3, and the nipple is provided on the axial opening 31 of the bottle body 3. As Figure 7 and Figure 11 shown, the connecting lid 2 is threadedly connected to the outer surface of the bottle body 3, and the end of the bottle body 3 provided with the axial opening 31 and the mounting ring 23 axially clamp and fix the base 12. In addition, a bottle cap 35 for covering the nipple body 1 is detachably provided on the bottle body 3.

[0062] Furthermore, please refer to Figure 11 and Figure 14 , a suction cup 32 is embedded inside the nipple body 1, and a straw 33 is provided inside the bottle body 3. One end of the straw 33 is connected to the suction cup 32 and the other end is a free end.

[0063] The suction cup 32 is assembled by an embedded method, which can ensure the convenience and quickness of the assembly of the suction cup 32 and the straw 33.

[0064] Furthermore, please refer to Figure 11 and Figure 14 , a straw gravity ball 34 is connected to the free end of the straw 33, and the straw 33 is a flexible structure and can deform under the drive of the straw gravity ball 34.

[0065] The straw 33 is movable within the bottle body 3. By setting the straw gravity ball 34, the position of the free end of the straw 33 can be changed according to the actual orientation of the feeding bottle and the gravitational effect of the straw gravity ball 34, so as to ensure that the milk in the feeding bottle can be completely drunk when the feeding bottle is placed upright or inverted.

[0066] In this specification, the various embodiments are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.

[0067] The nipple and the feeding bottle provided by the present invention have been introduced in detail above. Specific examples are used herein to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
