[0027] To better illustrate the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the embodiments of the present application. The singular forms "a", "the", and "said" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0029] Embodiment 1

[0030] Combined with Figure 1 and Figure 2 As shown, the present invention discloses a bottle cap structure, including:

[0031] A bottle cap body 1, which has a liquid outlet 11;

[0032] An air inlet pipe 2, which is arranged on the bottle cap body 1. The air inlet pipe 2 has an air inlet 21 and an air outlet 22, and the air outlet 22 is arranged lower than the air inlet 21.

[0033] In one embodiment, the air inlet pipe 2 is arranged in a circular tube shape. The circular cross-section enables the air flow to diffuse evenly along the pipe wall, reducing turbulent interference and improving the air pressure compensation efficiency; or the air inlet pipe 2 is arranged in an oval tube shape. When the oval cross-section is subjected to bending or torsional forces, the stress distribution is more uniform and the anti-deformation ability is strong; or the air inlet pipe 2 is arranged in a polygonal tube shape. The polygonal cross-section (such as a hexagon or a rectangle) disperses the external load through the edge design, and the stress distribution is more uniform when subjected to bending or torsional forces, and the compression and anti-deformation ability is better than that of a traditional circle. The tubular structures with different cross-sectional shapes can be selected according to actual needs.

[0034] In one embodiment, the air inlet pipe 2 includes a vertical section and / or an inclined section and / or a bent section, that is, the air inlet pipe 2 can be composed of a vertical section pipe, an inclined section pipe, and a bent section pipe alone or in combination. The multi-morphological design of the air inlet pipe 2 adapts to the requirements of different bottle body structures (such as narrow-mouth bottles and special-shaped bottles), improves versatility, and the bent pipe or the zigzag pipe composed of inclined sections can extend the air intake path and prevent liquid backflow.

[0035] In one embodiment, the air inlet pipe 2 is integrally connected to the bottle cap body 1, eliminating the sealing hidden danger of the split structure, increasing the airtightness; simplifying the production process and reducing the assembly cost.

[0036] In one embodiment, the cap body 1 has a liquid reflux chamber 12, and the liquid outlet 11 and the air inlet 21 are located within the liquid reflux chamber 12. Among them, the air inlet pipe 2 extends downward from the bottom of the liquid reflux chamber 12, the air inlet 21 is located on the inner bottom surface of the liquid reflux chamber 12, and the liquid outlet 11 is arranged higher than the air inlet 21. Thus, when using this cap structure to pour liquid, especially when the liquid pouring ends, part of the liquid will naturally flow along the outer surface of the liquid outlet 11 to the bottom surface of the liquid reflux chamber 12 and then back to the containing bottle for storing the liquid through the air inlet 21; after the liquid completely flows back to the containing bottle, the air inlet pipe 2 can still play the role of replenishing gas for the containing bottle.

[0037] Further, to enable the liquid to flow to the liquid reflux chamber 12, the height of the liquid outlet 11 is set lower than the height of the liquid reflux chamber 12.

[0038] Further, the liquid outlet 11 is arranged closely against the inner wall surface of the liquid reflux chamber 12, making the liquid outlet deviate towards one side of the cap structure, which is convenient for users to pour the liquid in the direction close to the liquid outlet, conforming to the usage habits of most users.

[0039] Since the height of the liquid outlet 11 is set lower than the height of the liquid reflux chamber 12, when the liquid outlet 11 is arranged closely against the inner wall surface of the liquid reflux chamber 12, the inner wall surface of the liquid reflux chamber 12 constitutes a part of the liquid outlet 11. When the liquid starts to be poured and when the pouring ends, the liquid that flows out to the top of the liquid outlet 11 and remains on the inner wall surface of the liquid reflux chamber 12 will flow back to the containing bottle through the liquid outlet 11 along the inner wall surface of the liquid reflux chamber 12, and the liquid that flows to both sides of the liquid outlet 11 will flow to the inner bottom surface of the liquid reflux chamber 12 and then back to the containing bottle through the air inlet 21 of the air inlet pipe 2.

[0040] In one embodiment, the cap structure further includes a cover body 3, the cover body 3 is connected to the cap body 1, and the cover body 3 has a closed position and a use position relative to the cap body 1 under the action of an external force. When the cover body 3 is in the closed position, the cover body 3 closes the liquid outlet 11 and the air inlet 21, which can prevent foreign objects from entering the inside of the containing bottle through the liquid outlet 11 and the air inlet pipe 2; when the cover body 3 is in the use position, the liquid outlet 11 and the air inlet 21 are exposed to the external environment for the liquid to be poured out through the liquid outlet 11 and for external gas to enter the containing bottle through the air inlet 21.

[0041] In one embodiment, the cover body 3 is detachably connected or rotatably connected to the cap body 1 to realize the position change of the cover body 3 relative to the cap body 1, so that the cover body 3 can be switched between the use position and the closed position.

[0042] When the cover body 3 is detachably connected to the bottle cap body 1, the cover body 3 and the bottle cap body 1 can be connected by threads or snap connection to achieve quick separation.

[0043] The present invention also discloses a storage bottle, which includes a containing bottle body and the bottle cap structure as described above. The bottle cap is connected to the containing bottle body. Among them, the air inlet pipe 2 extends into the upper position of the containing bottle body, and the air outlet 22 is located inside the containing bottle body.

[0044] Advantages of the present invention:

[0045] By providing the air inlet pipe 2, when pouring the liquid, the liquid is poured out through the liquid outlet 11, and the outside air enters the inside of the containing bottle body connected to the bottle cap structure through the air inlet pipe 2 to supplement the gas inside the containing bottle body, balance the air pressure difference between the inside of the containing bottle body and the outside environment, and avoid the situation of intermittent outflow or splashing when pouring the liquid, effectively ensuring the stability and smoothness of liquid pouring.

[0046] Embodiment 2

[0047] The difference between Embodiment 2 and Embodiment 1 is that the position of the liquid outlet 11 is different.

[0048] Combined with Figure 3 As shown, without affecting the understanding, Figure 3 the bottle cap is omitted. The liquid outlet 11 is arranged close to the inner wall surface of the liquid return cavity 12, making the liquid outlet 11 deviate towards one side of the bottle cap structure 1, so that the user can pour the liquid in the direction close to the liquid outlet, which conforms to the usage habits of most users.

[0049] Since the height of the liquid outlet 11 is set lower than the height of the liquid return cavity 12, if the bottle cap structure adopts the structural design with the liquid outlet 11 arranged close to the inner wall surface of the liquid return cavity 12, when the liquid starts to be poured and the pouring ends, the liquid flowing out of the outside of the liquid outlet 11 will flow into the liquid return cavity 12 through the outside of the liquid outlet 11 and return to the inside of the containing bottle body through the air inlet 21 of the air inlet pipe 2.
