Description

TECHNICAL FIELD

[0001] The utility model relates to the field of bottle cap especially relates to a drinking structure with additive, cap and drinking bottle. BACKGROUND

[0002] With the acceleration of modern life pace, people's demand for the health and diversity of drinks is increasing. Traditional drinking water is often limited to boiled water, which is healthy and harmless, but its monotonous and tasteless characteristics cannot meet the diversified needs of consumers for taste and drinking experience. This monotony not only reduces people's willingness to drink water, but also may lead individuals to choose sugar-containing or other additive-containing beverages to make up for the lack of boiled water in taste, thereby increasing the incidence of chronic diseases such as obesity and diabetes. In order to cope with this challenge, a series of technical innovations aimed at improving the drinking experience have appeared on the market in recent years. Among them, a relatively popular solution is to integrate a flavor component in the bottle cap part of the drinking container, especially to use a scent release technology to stimulate the sense of smell and increase the appeal of drinking water, thereby increasing the user's interest in drinking. This design not only enriches the flavor of drinking water, but also provides users with a more enjoyable and personalized drinking experience without changing the water quality itself.

[0003] However, the prior art has significant defects in implementing this function. The first problem is that the structure of the flavor component is relatively complex, which not only increases the production cost, but also leads to an increase in the overall volume of the drinking container, making it inconvenient to carry and store. In particular, in outdoor or travel scenarios, users have a strong demand for portability, and excessive volume will directly affect the market acceptance of the product. At the same time, the complex structure also poses a challenge to the sealing performance, which is a key factor in ensuring the cleanliness and freshness of the drinking container. If the sealing design between the flavor component and the bottle cap is not proper, it is easy to cause water leakage or external contaminants to enter, which not only affects the safety of drinking, but also may damage the flavor component, leading to unstable or ineffective scent release. SUMMARY

[0004] The utility model aims at overcoming the defects of the prior art that the structure of the flavor component is relatively complex, leading to a large overall volume and poor sealing performance.

[0005] The technical scheme adopted by the utility model is to provide a drinking structure with additive, comprising: a main body, a suction structure arranged on the main body, and a liquid channel penetrating through the main body and the suction structure; the main body comprises: a containing cavity for placing additives; an air inlet hole communicating with the containing cavity and the outside; and an air outlet hole communicating the containing cavity with the liquid channel.

[0006] By designing a simple main body structure including a containing cavity, an air inlet hole and an air outlet hole, the containing cavity is directly arranged in the main body connected with the suction structure instead of being part of an independent accessory or bottle cap, which reduces the number of parts, reduces the overall size, makes the overall structure more compact, easy to manufacture and assemble, and effectively simplifies the complexity of the flavor adding assembly. At the same time, since the containing cavity, air inlet hole and air outlet hole are integrated inside the main body and closely connected with the liquid channel, it is easier to prevent leakage of additives and entry of air and moisture into the additives, thereby maintaining the freshness and effectiveness of the additives and achieving good sealing effect.

[0007] In addition, the containing cavity is arranged in the main body and fixed by the connection of the main body with the suction structure, so that the additive assembly cannot fall off or shift, which improves the stability and reliability of the overall structure. Furthermore, since the suction structure can be replaced as a whole, when the additive is exhausted or needs to be replaced, the entire suction structure can be easily replaced without worrying about the residual flavor affecting the subsequent drinking experience, which can effectively avoid the problem of flavor mixing.

[0008] Further, the main body includes a hollow upper shell and a hollow lower shell, and the upper shell and the lower shell are combined to form a containing cavity to contain the flavor additive, which facilitates replacement of the additive or cleaning of the structure when needed. The upper shell is provided with an upper communication structure, and the lower shell is provided with a lower communication structure. One end of the upper communication structure communicates with the suction structure, and the other end cooperates with the lower communication structure to form a conduit structure. The liquid channel is formed in the conduit structure, and the conduit structure separates the liquid channel from the containing cavity to avoid mutual penetration of the additive and the liquid, thereby improving the sealing performance, ensuring the purity and taste of the drinking water, and maintaining the freshness and effectiveness of the additive. At the same time, such design also makes the assembly process simpler.

[0009] Further, the containing cavity surrounds the lower communication structure, the air inlet hole is arranged on the side surface or top surface or the intersection of the side surface and the top surface of the main body, the air outlet hole is arranged on the side of the conduit structure away from the air inlet hole, and the guide channel is formed to communicate the air inlet hole and the air outlet hole in two or more paths, so that the gas can fully carry out the flavor of the additive. In a limited space, by enlarging the distance between the air inlet hole and the air outlet hole, an effective air flow path can be formed to enable the external airflow to more fully combine with the additive, thereby improving the adding efficiency and making the volatilization of the additive more uniform, and improving the persistence and stability of the olfactory perception.

[0010] Further, the conduit structure forms a rigid support inside the main body, meets the basic requirements of liquid transmission, and can resist external pressure or impact, avoiding functional failure or safety hazards caused by deformation of the main body, enhancing the overall structural stability of the main body, and making the main body more solid and durable.

[0011] The conduit structure is fitted with a flexible sleeve that provides sealing and buffering. The flexible sleeve is connected to the vent and forms a conductive structure for one-way liquid flow, preventing liquid from flowing back into the containment cavity through the vent. This avoids direct contact and mixing between the liquid and the additive, maintaining the purity of the drinking water and extending the service life of the additive, ensuring its long-term preservation and effectiveness.

[0012] Furthermore, the flexible sleeve is a ring-shaped elastic element, with one end connected to the upper cover and the other end connected to the lower cover. This makes the connection between the upper and lower connecting structures more stable, and further enhances the separation effect between the receiving cavity and the liquid channel, except for the vent, preventing direct contact between the additive and the liquid and ensuring the purity of the drinking water. One side of the flexible sleeve protrudes into the vent to form a conductive structure. The conductive structure has a self-closing slit under normal conditions. The receiving cavity forms a one-way connection with the liquid channel through the slit. When the user draws water through the suction structure, the external suction acts on the slit, and the slit opens using its own elastic properties, allowing gas (carrying the aroma of the additive) to pass through, thus achieving the one-way conduction function. When the user stops drawing water, the slit recovers its elasticity to form a self-closing slit under normal conditions, ensuring effective isolation between the additive and the liquid channel.

[0013] Furthermore, a flavoring additive is provided within the receiving cavity to add aroma to the liquid. An external connecting structure is also provided on the lower shell. Through this external connecting structure and a matching cover, the main body can be quickly installed and replaced to accommodate more containers, improving ease of use. It also allows users to change different flavors or types of additives at any time according to personal preferences and needs, further enriching drinking options. A gripping part is also provided between the suction structure and the main body. The gripping part includes a protrusion extending horizontally outward from the suction structure and / or a recessed part extending horizontally inward from the suction structure, providing users with better leverage points and gripping methods, accommodating different hand shapes and offering better adaptability. When an adsorption force is applied to the suction structure, external air enters the receiving cavity through the air inlet, carrying the aroma of the flavoring additive outward. The aroma-laden air enters the liquid channel through the air outlet and flows towards the suction structure.

[0014] The second technical scheme of the utility model discloses a cover of a drinking bottle, which comprises a cover seat and a drinking structure with additives as described in the preceding technical scheme, and the drinking structure with additives is combined with the cover of the drinking bottle, so that the user can apply the drinking structure to various types of drinking bottles without any modification or customization of the bottle body, thereby improving the practicality and convenience.

[0015] Further, the cover seat comprises a concave mounting position, and the drinking structure is arranged on the mounting position, so that the drinking structure can be embedded in the cover seat, thereby saving space, making the connection between the drinking structure and the cover seat more firm, and increasing the protection of the drinking structure to a certain extent.

[0016] Further, the side surface of the cover seat is provided with an inner recessed sleeve joint position, and an elastic sealing ring is sleeved on the sleeve joint position, and a plurality of air channels are arranged on the elastic sealing ring, which balances the air pressure inside and outside the drinking bottle.

[0017] The third technical scheme of the utility model discloses a drinking bottle, which comprises a bottle body and a connecting pipe, and a cover of a drinking bottle as described in the second technical scheme, the cover is arranged on the bottle opening of the bottle body, one end of the connecting pipe is connected with the cover seat and communicates with the liquid channel, and the other end extends into the bottle body.

[0018] Compared with the prior art, the beneficial effects of the utility model are that: through design one contains accommodating cavity, air inlet hole and air outlet hole simple main body structure, and accommodating cavity is directly arranged in the main body of connecting suction structure, the number of parts is reduced, thereby the overall volume is reduced, the overall structure is more compact, easy to manufacture and assemble, effectively simplify the complexity of adding taste component. Accommodating cavity is arranged in the main body, and is fixed through the connection of the main body and the suction structure, so that the additive component cannot fall off or displace, the stability and reliability of the whole structure are improved.

[0019] Through design two or more ways respectively communicate the guide channel of air inlet hole and air outlet hole, make the gas fully take out the smell of additive, and in the limited space, through the distance of air inlet hole and air outlet hole is enlarged, forms effective air flow path, improved the adding efficiency, made the volatilization of additive more uniform, improved the persistence and stability of olfactory perception. The duct structure forms rigid support in the main body, can resist external pressure or impact, avoids the functional failure or security risk caused by the deformation of the main body, enhances the overall structural stability of the main body. The flexible sleeve connector of duct structure is set on the sleeve and forms the guide structure of one-way communication liquid channel, prevents liquid from flowing back into the accommodating cavity through the air outlet hole, not only maintains the purity of drinking water, but also prolongs the service life of the additive.

[0020] Through the combination of the drinking structure with additive and the cover of drinking bottle, the user can apply the drinking structure to various types of drinking bottles without any modification or customization of the bottle body, improving its practicality and convenience. At the same time, the drinking structure and the cover are designed to be detachable, so that the user can easily change the taste and clean and maintain it. The side of the cover seat is provided with an inner recessed sleeve joint and a flexible sealing ring sleeved on the sleeve joint, and a plurality of air channels are provided on the flexible sealing ring, which balances the air pressure inside and outside the drinking bottle, making the water suction process more easy and smooth, avoiding problems such as liquid splashing or leakage caused by unbalanced air pressure.

The upper shell 120 is internally provided with an upper communication structure 121, and the upper shell 120 is integrally formed with the suction structure 101 and the upper communication structure 121. The lower shell 130 is internally provided with a lower communication structure 131, and the lower shell 130 is integrally formed with the lower communication structure 131. The hollow upper shell 120 and the hollow lower shell 130 are tightly combined by thread connection, buckle connection or sleeve connection, etc. Figure 3 and Figure 4 As shown, the upper and lower shells enclose the main body 100 inside to form a sealed circular annular accommodating cavity 103, which is used for placing the flavor additives.

[0040] As shown, Figure 4 and Figure 5 The upper communication structure 121 is communicated with the suction structure 101 at one end and cooperated with the lower communication structure 131 to form a conduit structure at the other end. The two are coupled together by setting a notch in the lower communication structure 131 matched with the outer diameter of the upper communication structure 121. The conduit structure is designed with smooth inner wall to form the liquid channel 102, and the conduit structure separates the liquid channel 102 from the accommodating cavity 103. The main body 100 is provided with an air inlet hole 111 for communicating the accommodating cavity 103 with the outside. The air inlet hole 111 has an outer diameter larger than an inner diameter of the accommodating cavity 103. The conduit structure is provided with an air outlet hole 112 for communicating the accommodating cavity 103 with the liquid channel 102. The main body 100 is made of food-grade high-strength plastic material.

[0041] The number of air inlet holes 111 is at least one or more. The air inlet hole 111 can be arranged on the side of the outer part of the accommodating cavity 103 of the main body 100, on the top of the outer part of the accommodating cavity 103 of the main body 100, or on the intersection of the side and the top of the outer part of the accommodating cavity 103 of the main body 100. The shape of the air inlet hole 111 can be circular, oval, rectangular, strip-shaped or waist-shaped, etc. which can be selected according to actual needs. In this embodiment, the air inlet hole 111 is one, which is strip-shaped and arranged on the side of the outer part of the accommodating cavity 103 of the main body 100.
