TECHNICAL FIELD

The present disclosure relates to the field of drinking devices, and in particular, to a drinking structure with an additive, a lid, and a drinking bottle.

BACKGROUND

With the acceleration of modern life pace, demands for healthiness and diversity of beverages are increasing. Traditional drinking ways are often limited to plain boiled water, which, although healthy and harmless, falls short in meeting diversified needs of consumers for flavor and drinking experience due to its bland and flavorless nature. Such monotony not only reduces the willingness of people to drink water but may also lead individuals to opt for beverages containing sugar or other additives to compensate for the lack of flavor in plain water, thereby increasing health risks such as the incidence of chronic diseases like obesity and diabetes. To address this challenge, a series of technological innovations aimed at enhancing the drinking experience have emerged on the market in recent years. A popular solution is to integrate a flavoring component into a bottle lid part of a drinking container, such as a structure for adding fragrance, particularly utilizing fragrance release technology to enhance the appeal of drinking water through olfactory stimulation and thus increase the interest of users in drinking. Such design not only enriches the flavor of the drinking water but also provides users with more enjoyable and personalized drinking experience without altering the water quality.

However, known structure in the prior art faces significant drawbacks in achieving the function. The primary problem lies in the relatively complex structural design of the flavoring component, which not only increases production costs but also enlarges the size of the entire drinking container, making it inconvenient for carrying and storage. Especially in outdoor or travel scenarios where users have a prominent need for portability, therefore the excessive size directly impacts the product market acceptance. Furthermore, the complex structure poses challenges for sealing performance which is a critical factor in ensuring cleanliness and freshness of water in the drinking container. Improper sealing design between the flavoring component and the bottle lid can easily lead to water leakage or infiltration of external contaminants, which not only affects drinking safety but may also damage the flavoring component, resulting in unstable or ineffective fragrance release.

Although the existing flavoring component, such as a fragrance-enhancing structure, has a certain fragrance-enhancing effect, which meets the consumer demands to a certain extent, a series of application problems still exist in practical use. Firstly, the existing fragrance-enhancing structure typically uses a fragrance ring. Additives such as fragrance are usually stored in a ring-shaped rigid shell, which shell is engaged with the soft bottle lid. In use, external air enters the fragrance ring, then enters the bottle lid, and finally enters a straw through a connector arranged on the straw to achieve fragrance enhancement. However, to maintain a smooth air passage, the rigid fragrance ring, the soft bottle lid, and the rigid straw connector are required to simultaneously cooperate, with tiny air holes among the three in precise alignment to meet the demand for fragrance enhancement. The stability of the complex assembly is unsatisfactory, and shifting or partial detachment is likely to happen whether during normal use or accidental collisions, not only causing a unsatisfactory air supply effect but also potentially leading to reverse liquid spillage that contaminates the fragrance ring, which influences drinking experience of consumers during long-term use, and may pose potential threats on hygienic safety of the drinking water. Due to factors such as the inevitable deformation of the soft bottle lid during use and possible incomplete matching when installing the fragrance ring, although many latch settings are currently used to reduce the difficulty of fitting, the problem cannot be effectively solved, leading to frequent maintenance and unsatisfactory experience. Additionally, the fragrance-enhancing component is usually designed with materials of different characteristics, and the combination of soft and hard materials is greatly affected by material deformation, causing the connector to be particularly prone to leakage. Reverse spillage of liquid can contaminate the additive along the air passage, further affecting the taste and flavor of the drinking water.

SUMMARY

The present disclosure aims to provide a drinking structure with an additive, a lid, and a drinking bottle, which overcome the defects of a large overall volume and unsatisfactory sealing performance caused by complex structural design of the flavoring component in the prior art, and further solves the problems of a unsatisfactory seasoning effect and potential structure contamination caused by easy displacement of the existing flavoring component structure during assembly.

In a first aspect, the present disclosure provides a drinking structure with an additive, including: a housing, a suction structure arranged on the housing, and a liquid passage passing through the housing and the suction structure. The housing includes: an accommodation cavity for containing the additive, an air inlet hole for communicating the accommodation cavity with an exterior, and an air outlet hole for communicating the accommodation cavity with the liquid passage.

According to the present disclosure, by designing a simple main structure that includes the accommodation cavity, the air inlet hole and the air outlet hole, with the accommodation cavity directly arranging within the body connected to the suction structure rather than as a separate accessory or a part of a bottle lid, the number of components is reduced, the overall volume is decreased, the overall structure is thus more compact and easy to manufacture and assemble, therefore complexity of an added flavor component is effectively simplified. In addition, the accommodation cavity, the air inlet hole and the air outlet hole are all integrated within the body and closely connected to the liquid passage, such structure more easily prevents the additive from leaking and air and moisture from entering the additive, thus preserving freshness and effectiveness of the additive, and achieving a good sealing effect.

Moreover, by integrating the accommodation cavity for containing the additive within the housing that is combined with the suction structure, the problems of obstructed gas flow and liquid backflow are solved, which are caused by unsatisfactory connection of the gas passage and a liquid passage, as in the assembly process of an existing flexible nozzle matched with an external fragrance ring, the gas passage and the liquid passage are difficult to align and are likely to shift during use. A stable connection between the gas passage and the liquid passage can still be maintained during normal drinking and accidental collisions in daily use, which reduces maintenance, as well as avoiding the failure of the fragrance ring due to improper connection, thereby achieve enhanced stability of the overall structure and reduced costs.

To further simplify the structure and enhance the stability, one side of the housing away from the suction structure is provided with a tube connecting segment for connecting an external straw and the liquid passage, and one side of the tube connecting segment close to the suction structure is provided with a limiting structure which is used to limit the length of the external straw extending into the liquid passage.

Due to the arrangement of the tube connecting segment, the structure is further simplified, fragrant gas and liquid are fully mixed within the liquid passage, and the arrangement of the limiting structure facilitates easier installation of the straw. In the present disclosure, the mixing of the fragrant gas and liquid occurs in the liquid passage, not at the straw connector in the prior art, therefore, it is unnecessary to consider the problem of alignment. Such configuration further enlarges a combination space for the gas and the liquid, thus avoiding interference and obstruction for the air outlet hole and maintaining smooth circulation of fragrance-enhancing gas. Different from a design in the prior art that a straw connector is required to be additionally arranged on the straw, and the air inlet hole in the straw connector needs to be further matched with the air outlet hole in assembly process, in the present disclosure, a stepped connector with a cross section gradually decreasing in size is preferably provided on one side of the housing, the tube connecting segment is formed at a connected position of the liquid passage and the exterior, and the limiting structure is formed by a minimum cross-section size to limit the insertion depth of the straw. It simply and ingeniously achieves required functions with the straw not required to be re-aligned in the liquid passage.

Specifically, the housing includes: an upper housing part and a lower housing part. In this case, the suction structure is connected to the upper housing part, and the upper housing part and the lower housing part are combined to form the accommodation cavity for containing the additive, facilitating installation and replacement of the additive as needed. An upper communication structure is arranged in the upper housing part, and a lower communication structure is arranged in the lower housing part. One end of the upper communication structure communicates with the suction structure, and the other end of the upper communication structure is nested into the lower communication structure. The upper communication structure and the lower communication structure are in nested fit to form a conduit structure. The liquid passage is arranged in the conduit structure. The accommodation cavity is thus separated from the liquid passage through the conduit structure in the present disclosure, which prevents the mutual infiltration of the additive and the liquid and thus enhancing sealing performance. Therefore, purity and taste of drinking water are ensured, and meanwhile the freshness and effectiveness of the additive are kept. Additionally, the mutual nesting of the upper communication structure and the lower communication structure extends a length of a splice seam, thereby enhancing an overall waterproof sealing effect of the conduit structure.

According to the present disclosure, the air inlet hole may be formed in a side surface of the housing, and/or a top surface of the housing, and/or a junction of the side surface and the top surface of the housing. One side of the conduit structure away from the air inlet hole is provided with the air outlet hole. The accommodation cavity surrounds the conduit structure, and forms at least two guiding passages that are respectively communicated with the air inlet hole and the air outlet hole. Such configuration allows the gas to fully carry out the fragrance of the additive. By increasing a distance between the air inlet hole and the air outlet hole within a limited space, an effective airflow path can be formed. This allows external airflow to be combined with the additive more fully. Therefore, the addition efficiency is improved, the additive is volatilized more uniformly, achieving improved durability and stability of olfactory perception.

To further enhance the sealing performance, a separation cavity surrounding the upper communication structure is formed in the upper housing part. A nested connector formed by fit of the upper communication structure and the lower communication structure is communicated with the separation cavity. After assembly, the separation cavity forms an air barrier that is communicated with the nested connector. Such air barrier may further improve the waterproof sealing effect of the conduit structure by utilizing its own gas pressure, thereby effectively overcoming the problem that the liquid passes through matching gaps and contaminates the additive.

According to a favorable embodiment, the conduit structure forms a rigid support inside the housing, particularly a cylindrical rigid support, which meets basic requirements for liquid transfer and can also resist external pressure or impact. Accordingly, functional failure or safety hazards caused by deformation of the body are avoided, overall structural stability of the body is enhanced, and the body is more stable and durable.

The conduit structure is sleeved with a flexible sleeve, and the flexible sleeve is matched with the air outlet hole to form a one-way conduction from the accommodation cavity to the liquid passage. The one-way conduction prevents the liquid from flowing back into the accommodation cavity through the air outlet hole, thereby avoiding direct contact and mixing between the liquid and the additive, keeping purity of the drinking water, also prolonging service life of the additive, and ensuring long-time preservation and effectiveness of the additive. In the present disclosure, the flexible sleeve serves both as a carrier for a one-way conduction structure and as a sealing structure for the conduit structure. Therefore, the flexible sleeve needs to be expanded in the process of sealing the conduit structure, so as to ensure a tight fit for the conduit structure. However, tensile force generated by the expansion, when applied to a cambered surface, can easily cause deformation of the air inlet hole. In the present disclosure, one side of the conduit structure is provided with a matching plane, and the air outlet hole is formed in the matching plane. The flexible sleeve is matched with the air outlet hole in the matching plane on the conduit structure. The arrangement of the matching plane not only facilitates installation and positioning but, more importantly, changes a direction of pulling the air outlet hole in the sleeving process. Setting the plane at one end to support the air inlet hole can effectively guide the tensile force after assembly, as a result, the air inlet hole only bears horizontal tension. Meanwhile, the one-way conduction is formed from the accommodation cavity to the liquid passage, which further protects dryness of the accommodation cavity, prevents the liquid from entering the accommodation cavity, and thus prolongs preservation time of the additive.

The flexible sleeve is preferably a ring-shaped elastic member. One end of the flexible sleeve is connected to the upper housing part, and the other end of the flexible sleeve is connected to the lower housing part, so that the connection between the upper communication structure and the lower communication structure is more stable. In addition, a separation effect between the accommodation cavity and the liquid passage except the air outlet hole is further enhanced, which prevents direct contact between the additive and the liquid, thereby ensuring the purity of the drinking water. After the upper housing part and the lower housing part are assembled, a lower edge of the upper communication structure abuts against an inner ring, and the flexible sleeve forms a barrier from an outer side of the outer ring, so that the separation cavity is sealed to form a sealed area, thereby further improving a sealing effect.

The flexible sleeve is specifically an elastic sealing ring, including: a plane segment matched with the matching plane, and a cambered segment that is connected end-to-end with the plane segment. The design of the plane segment reduces the machining difficulty of the air outlet hole, and the combination of the plane segment and the cambered segment meets the requirements of the ring-shaped flexible sleeve for plane matching.

The plane segment is provided with a spherical self-sealing structure. The air outlet hole is designed as a conical channel. A cross section of one side of the conical channel close to the liquid passage is smaller than a cross section of one side of the conical channel away from the liquid passage. The self-sealing structure is matched with the conical channel, and is embedded in the conical channel. The self-sealing structure includes a self-closing slit. The conical channel and the slit are matched to form the one-way conduction from the accommodation cavity to the liquid passage, thereby allowing the slit to only open towards the side with the smaller cross section (i.e., the liquid passage direction) and making it difficult to open in a reverse direction, and thus further improving the sealing effect.

The additive may be any one kind of the additives adapted for water drinking, and preferably a fragrance additive, such as a fragrance enhancer, to add a scent to the liquid.

The lower housing part may be further provided with a connection structure for externally connecting other components. Through such connection structure and a lid body matched with the connection structure, rapid installation and replacement of the housing can be achieved, which is adapted to more containers.

A surface of the suction structure may be provided with a convex portion extending towards the air inlet hole. A concave portion is arranged on one side of the suction structure away from the convex portion. The convex portion and the concave portion form an ergonomically designed gripping portion, thereby facilitating a user to rotate and install a drinking structure. In addition, the convex portion may also effectively reinforce a connection between the upper housing part and the suction structure, thereby enhancing the overall strength of the housing. A protrusion is formed on a back side of the concave portion, which further enhance overall structural strength, so as to resist bending from external force and prevent displacement and deformation of the air inlet hole. When suction force is applied to the suction structure, a small part of suction force acts on the air inlet hole, thereby allowing the external air to enter the accommodation cavity through the air inlet hole and carry out the fragrance of the additive, and the air with fragrant enters the liquid passage through the air outlet hole and flows towards the suction structure through the liquid passage.

In another aspect, the present disclosure provides a lid for a drinking bottle, including: a lid base and any one of the foregoing drinking structures with an additive. By combing the drinking structure with an additive and the lid for the drinking bottle, the user can apply the drinking structure to various types of drinking bottles without any transformation or customization to a bottle body, thereby improving practicality and convenience. Meanwhile, the coordinated design of the lid base and the drinking structure not only ensures the stability and reliability of the drinking structure during use but also allows the user for convenient assembly and replacement. The user can connect the drinking structure with the drinking bottle only by simply installing the drinking structure on the lid base, without any complex operations or tools. Additionally, due to the detachable design of the drinking structure and the lid, the user can easily change flavors and perform cleaning and maintenance, which facilitates use and ensures hygiene and safety during use.

Specifically, the lid base includes a recessed installation position. The drinking structure is arranged at the installation position, so that the drinking structure can be embedded in the lid base. Such constructure can save space, also make the connection between the drinking structure and the lid base firmer, and further enhance protection of the drinking structure to a certain degree. The lid base may further include a connecting passage. The connecting passage passes through the lid base to communicate with the liquid passage. In order to improve sealing performance of the connection, a sealing ring may be further arranged between the drinking structure and the lid base, which can not only prevent liquid leakage but also ensure that the drinking water is stably transferred into the housing to improve a transfer effect.

Further, a side surface of the lid base may be provided with a concave sleeving position and an elastic sealing loop sleeving the sleeving position, and the elastic sealing loop is preferably provided with a plurality of air passages. With such configuration, balance of air pressure inside and outside the drinking bottle is achieved. This is particularly important when the user is drinking or drinking continuously, because as the liquid in the bottle decreases, the air pressure inside the bottle gradually decreases to increases difficulty in water suction. The design of the air passages allows the external air to enter the bottle through the air passages to compensate for the air pressure reduced due to the decrease in liquid, which makes water suction easier and smoother, while also avoiding the problems such as liquid splashing or leaking caused by air pressure imbalance.

The present disclosure further provides a drinking bottle, including a bottle body, a connecting tube, and any one of the foregoing drinking structures with an additive or any one of the foregoing lids at a bottle opening of the bottle body. The lid is covered on the bottle opening of the bottle body, one end of the connecting tube is connected to the lid base and communicated with a liquid passage, and the other end of the connecting tube extends into the bottle body.

Compared with the prior art, the present disclosure can effectively avoid mutual infiltration of the additive and the liquid, ensure purity and taste of the drinking water, and maintain freshness and effectiveness of the additive, by combining the upper housing part and the lower housing part to form the accommodation cavity and forming the conduit structure through a nested fit of the upper communication structure and the lower communication structure. Additionally, the arrangement of the air barrier further enhances the waterproof sealing effect of the conduit structure, and enhances overall performance of a product. In the aspect of enhancing the gas passage efficiency, the reasonable layout of the air inlet hole and the air outlet hole, as well as the design of the guiding passages, allows external airflow to more fully combine with the additive, thereby improving the addition efficiency, ensuring a more uniform volatilization of the additive, and enhancing durability and stability of olfactory perception.

By designing two or more guiding passages that respectively communicate with the air inlet hole and the air outlet hole, the air can fully carry out the flavor of the additive. Within the limited space, by increasing the distance between the air inlet hole and the air outlet hole, the effective airflow path is formed, which improves the addition efficiency, ensures a more uniform volatilization of the additive, and enhances the durability and stability of the olfactory perception. The conduit structure forms a rigid support inside the housing, which can resist external pressure or impact, avoid functional failure or safety hazards caused by housing deformation, and enhance overall structural stability of the housing. The conduction structure that is in one-way communication with the liquid passage formed by the flexible sleeve sleeving the conduit structure can prevent the liquid from flowing back into the accommodation cavity through the air outlet hole, which not only keeps the purity of the drinking water, but also prolongs the service life of the additive.

By combing the drinking structure with an additive and the lid for the drinking bottle, the user can apply the drinking structure to various types of drinking bottles without any transformation or customization to a bottle body, thereby improving practicality and convenience. Meanwhile, due to the detachable design of the drinking structure and the lid, the user can easily change flavors and perform cleaning and maintenance. With the configuration that the side surface of the lid base of the lid is provided with the concave sleeving position and the elastic sealing loop sleeving the sleeving position, and the elastic sealing loop is provided with the plurality of air passages, balance of the air pressure inside and outside the drinking bottle can be achieved, making the process of water suction easier and smoother, and avoiding the problems such as liquid splashing or leaking caused by air pressure imbalance.

DETAILED DESCRIPTION

The accompanying drawings of the present disclosure are merely for exemplary descriptions, and should not be construed as a limitation on the present disclosure. To better illustrate the following embodiments, some components in the accompanying drawings may be omitted, enlarged, or reduced, which does not represent an actual product size. For those skilled in the art, it is understandable that some well-known structures and descriptions thereof in the accompanying drawings may be omitted.

FIG. 1 to FIG. 3 provide a drinking structure with an additive, including a housing 100, a suction structure 101 arranged on the housing 100, and a liquid passage 102 (shown in FIG. 5) passing through the housing 100 and the suction structure 101. The housing 100 is detachably divided into a hollow upper housing part 120 and a hollow lower housing part 130. The upper housing part 120 is internally provided with an upper communication structure 121 (shown in FIG. 6), and the upper housing part 120 is integrally formed with the suction structure 101 and the upper communication structure 121. The lower housing part 130 is internally provided with a lower communication structure 131, and is integrally formed with the lower communication structure 131. The hollow upper housing part 120 and the hollow lower housing part 130 are tightly connected through known methods such as a threaded connection, a snap-fit connection, or a sleeve joint. As shown in FIG. 3 and FIG. 5, the upper housing part 120 and the lower housing part 130 are enclosed to form a sealed annular accommodation cavity 103 inside the housing 100. The accommodation cavity 103 is used to contain the additive. One side of the housing 100 away from the suction structure 101 is provided with a tube connecting segment 104 for connecting an external straw and the liquid passage 102. One side of the tube connecting segment 104 close to the suction structure is provided with a limiting structure 105 which is used to limit the length of the external straw extending into the liquid passage 102.

In combination with FIG. 4 and FIG. 5, in this embodiment, the upper communication structure 121 is in a circular tube shape, with a lower edge extending to a middle portion of an air outlet hole 112. The lower communication structure 131 is in a circular tube shape matched with the upper communication structure 121, and includes an inner ring 143 and an outer ring 144 which are connected with each other, with the outer ring 144 higher than the inner ring 143. The inner ring 143 abuts against the lower edge of the upper communication structure 121, and an inner diameter of the upper communication structure 121 is smaller than that of the inner ring 143, so that the upper communication structure 121 partially protrudes into the liquid passage 102 to form a secondary limit on the straw. An inner wall of the outer ring 144 fits against an outer wall of the upper communication structure 121, thereby allowing the upper communication structure 121 to be nested in the lower communication structure 131.

The upper communication structure 121 and the lower communication structure 131 are formed into a conduit structure. The interior of the conduit structure is designed with a smooth inner wall to form the liquid passage 102, so that the conduit structure separates the liquid passage 102 from the accommodation cavity 103. The housing 100 is provided with an air inlet hole 111 for communicating the accommodation cavity 103 with the exterior. The diameter of the air inlet hole 111 outside the accommodation cavity 103 is greater than the diameter of the air inlet hole 111 inside the accommodation cavity 103. The conduit structure is provided with an air outlet hole 112 for communicating the accommodation cavity 103 with the liquid passage 102. The housing 100 is preferably made of a food-grade high-strength plastic material.

At least one or more air inlet holes 111 are arranged, which may be arranged in an outer side surface of the accommodation cavity 103 of the housing 100, an outer top surface of the accommodation cavity 103 of the housing 100, or a junction of the outer side surface and the outer top surface of the accommodation cavity 103 of the housing 100. The air inlet hole 111 may be circular, oval, rectangular, strip-shaped, kidney-shaped, or the like, which may be selected according to actual needs. In this embodiment, one strip-shaped air inlet hole 111 is arranged, which is arranged in the outer side surface of the accommodation cavity 103 of the housing 100.

With reference to FIG. 5, FIG. 6, and FIG. 7, the air outlet hole 112 is arranged in one side of the conduit structure away from the air inlet hole 111. The accommodation cavity 103 surrounds the lower communication structure 131, and at least forms two guiding passages (indicated by arrows in FIG. 7) that respectively communicate with the air inlet hole 111 and the air outlet hole 112, thereby allowing gas to travel as far as possible within the accommodation cavity 103, and fully carry fragrance out of the accommodation cavity 103 and into the liquid passage 102 from the air outlet hole 112.

The suction structure 101 includes a nozzle and a structural cavity. The nozzle is arranged at one end away from the upper housing part 120 and forms a suction port of the liquid passage 102. The structural cavity is communicated with an interior of the upper housing part 120. An upper end of the upper communication structure 121 is connected to the nozzle, and a lower end of the upper communication structure 121 is matched with the lower communication structure 131. An interval is formed between the upper communication structure 121 and an inner wall of the structural cavity, and such interval forms a separation cavity 122. A nested connector formed by fit of the upper communication structure 121 and the lower communication structure 131 is communicated with the separation cavity 122. The conduit structure forms a cylindrical rigid support inside the housing 100. One side of the conduit structure is provided with a matching plane 132, and the air outlet hole 112 is formed in the matching plane 132. The conduit structure is covered with a flexible sleeve 140. The flexible sleeve 140 includes a plane segment 141 matched with the matching plane 132, and a cambered segment 142 that is connected end-to-end with the plane segment 141. The plane segment 141 is provided with a spherical self-sealing structure. The air outlet hole 112 is a conical channel with a cross section of one side of the conical channel close to the liquid passage 102 smaller than a cross section of one side of the conical channel away from the liquid passage 102. The self-sealing structure is matched with the conical channel, and is embedded in the conical channel. The self-sealing structure includes a self-closing slit 150. The conical channel and the slit 150 are matched to form a one-way conduction from the accommodation cavity 103 to the liquid passage 102. The flexible sleeve 140 is a ring-shaped elastic member. One end of the flexible sleeve 140 is connected to the upper communication structure 121 of the upper housing part 120, and the other end of the flexible sleeve 140 is connected to the lower communication structure 131 of the lower housing part 130. After the upper housing part 120 and the lower housing part 130 are assembled, the lower edge of the upper communication structure 121 abuts against the inner ring 143, and the flexible sleeve 140 forms a barrier from an outer side of the outer ring 144. A height of the flexible sleeve 140 is equal to an internal height of the accommodation cavity 103 after the upper housing part 120 and the lower housing part 130 are assembled.

Now referring to FIG. 8, one side of the flexible sleeve 140 is protruded into the air outlet hole 112 to form the self-sealing structure, and the self-sealing structure is provided with the self-sealing slit 150. The self-sealing slit 150 is designed as a cross-shaped slit 150, and the accommodation cavity 103 is in one-way communication with the liquid passage 102 through the slit 150. When a user sucks water through the suction structure 101, as external suction acts on the cross-shaped slit 150, the cross-shaped slit 150 opens using elastic properties and allows gas (fragrance of the additive are carried) to pass through, thereby achieving a one-way conduction function. When the user stops sucking water, the cross-shaped slit 150 recovers to the self-sealing slit 150 in a normal state under elasticity, thereby ensuring effective isolation between the additive and the liquid passage 102.

The additive is arranged in the accommodation cavity 103, which may specifically be a solid fragrance sachet, a fragrance ring, fragrance particles, or the like, and may be adjusted according to actual application requirements.

Referring back to FIG. 3, the lower housing part 130 is further provided with a connection structure 170 for connecting external component. The connection structure 170 may be a thread, a snap fit, a ring-shaped protruding strip, a ring-shaped groove, a transition fit, etc., which may be adjusted according to actual application requirements.

Referring back to FIG. 2, a gripping portion 110 is further arranged between the suction structure 101 and the housing 100. Specifically, a surface of the suction structure 101 is provided with a convex portion extending towards the air inlet hole, namely a convex ridge 1011. A concave portion, namely a concave cambered surface 1012 is formed on one side of the suction structure 101 opposite to the ridge 1011. The gripping portion 110 is formed by the ridge 1011 and the cambered surface 1012. When suction force is applied to the suction structure 101, a small part of suction force acts on the air inlet hole 111 to allow the external air to enter the accommodation cavity through the air inlet hole, and such air thus carry the fragrance out of the additive and into the liquid passage 102 through the air outlet hole 112.

FIG. 9 and FIG. 10 provide a lid for a drinking bottle, which includes a lid base 200 and the foregoing drinking structure with the additive. The drinking structure is coupled within the lid base 200. The lid base 200 is circular or is in a shape fitted with a size of a bottle opening of the drinking bottle. The lid base 200 has an edge designed with a matching structure for a tight connection with the bottle opening. The matching structure may be a thread, a snap fit, a protruding strip, a groove, a transition fit, or the like, which may be adjusted according to an actual bottle opening structure, to ensure sealing performance and stability.

With reference to FIG. 10, FIG. 11, and FIG. 12, a middle of the lid base 200 is provided with a recessed installation position 201, with a depth and a diameter adaptive to the drinking structure with additive mentioned above, as well as a connecting structure 202 penetrating through the lid base 200. The connecting structure 202 is preferably a cylindrical passage penetrating through a bottom of the lid base 200, with the diameter thereof matched with the liquid passage 102 in the drinking structure, thereby ensuring a seamless connection between the two. One end of the connecting structure 202 is located at the bottom of the installation position 201 and connected to the liquid passage 102, and the other end of the connecting structure 202 extends to the bottom of the lid base 200.

The drinking structure, as a core component of the lid, has the housing 100 (including the upper housing part 120 and the lower housing part 130) installed inside the lid base 200, and a stable connection therebetween is achieved through methods such as a thread, a snap fit, or a sleeve joint. A top of the upper housing part 120, namely the installation position of the suction structure 101, is slightly higher than a surface of the lid base 200, which allows the user to directly operate, and the lower housing part 130 tightly fits against the bottom of the lid base 200. A sealing ring 210 is further arranged between the drinking structure and the lid base 200. The bottom of the lid base 200 is correspondingly provided with a sealing groove for containing the sealing ring 210. The sealing ring 210 is preferably a ring-shaped elastic sealing ring 210, surrounding the connecting structure 202. In addition, a gap is further formed between the housing 100 and the lid base 200 to facilitate air inflow of an air inlet.

In order to facilitate assembly and disassembly of the drinking structure, the edge of the installation position 201 is designed with a slight tilt or chamfer.

In combination with FIG. 10 and FIG. 13, an upper diameter of the lid base 200 is greater than a lower diameter. An upper portion of a side surface of the lid base 200 and a transition area between the upper portion and a lower portion are respectively provided with a concave sleeving position 203. Specifically, the sleeving position 203 at the upper portion of the side surface of the lid base 200 is in a notch shape, and a middle area between the upper portion and the lower portion is provided with the concave ring-shaped sleeving position 203.

The ring-shaped sleeving position 203 is mounted with an elastic sealing loop 220 matched in shape and size. The elastic sealing loop 220 is divided into an upper portion, a middle portion and a lower portion. The upper portion is tightly covered with the sleeving position 203 in the notch shape at the upper portion of the side surface of the lid base 200, with a height kept flush with a top surface of the lid base 200. The middle portion and the lower portion are sleeved with the concave ring-shaped sleeving position 203 between the upper portion and the lower portion of the side surface of the lid base 200. A diameter of the middle portion of the elastic sealing loop 220 is equal to a diameter of the upper portion of the side surface of the lid base 200, and a diameter of the lower portion is matched with a diameter of a lower portion of the side surface of the lid base 200. Additionally, the upper portion of the elastic sealing loop 220 that is covered with the notched sleeving position 203 at the upper portion of the lid base 200 is further provided with a plurality of air passages 221 straightly penetrating through the entire elastic sealing loop 220. A notch is further formed in the lower portion of the lid base 200 to allow the air passages 221 to vent smoothly. During installation, the sleeving position 203 is sleeved with the elastic sealing loop 220, and the elastic sealing loop 220 tightly fits against an inner wall of the sleeving position 203 through elasticity, thereby improving sealing performance of the entire lid for the drinking bottle, and also ensuring smoother and easier suction experience for the user during continuous drinking.

FIG. 14 and FIG. 15 provide a drinking bottle, which includes a bottle body 300 and a connecting tube 310, and further including the foregoing drinking structure arranged at a bottle opening of the bottle body 300, or the foregoing lid. The bottle body 300 may be designed in various shapes to meet capacity specifications according to actual needs, with a material selected from food-grade plastic or glass to ensure safety and durability. A bottom of the bottle body 300 has a stable design to facilitate placement, and a body portion of the bottle is smooth, making it easy to clean.

Reference to FIG. 16 and FIG. 17, the connecting tube 310 may be designed as a rigid tube or a flexible tube according to actual needs. One end of the connecting tube 310 is designed with a connection port matched with the lid base 200 for a tight connection with the connecting passage formed by the connecting structure 202 on the lid base 200 to ensure that liquid can flow smoothly from the interior of the bottle body 300 into the liquid passage 102. The other end of the connecting tube 310 extends into the bottle body 300. Additionally, a tiny filter hole or a filter mesh may also be additionally arranged at a tail end of the connecting tube 310 to prevent impurities in the bottle body 300 from entering the connecting tube 310.

The lid for the drinking bottle is arranged on the bottle opening of the bottle body 300. The connection method for the lid base 200 and the bottle opening may be a threaded connection, a snap-fit connection, a protruding strip and groove fitting connection, a transition fitting connection, etc., to ensure sealing performance and stability. During installation, the user may easily complete the installation only by rotating or pressing the lid base 200 onto the bottle opening.
