[0033] The present application provides a cup cover, which, through a rotatable top cover (1) and a sealing mechanism (3) that rotates synchronously therewith, allows the user to easily switch the exposed state of the direct drinking hole (21) or the straw (22) as required, thereby improving the convenience and experience of use. In addition, the design of the cup cover of the present invention also takes into account the requirements of easy assembly and disassembly, so that the user can easily clean and maintain the cup cover during use. By opening a through hole (23) on the main cover (2) and designing the structure of the end portion (11) and the embedded portion (12), the top cover (1) can be stably assembled on the main cover (2) and is easy to disassemble.

[0034] like Figure 1-9As shown, an embodiment of the present application provides a cup cover, comprising: a top cover (1), a main cover (2), and a sealing mechanism (3), wherein the main cover (2) can be fixed on the cup body (0), the top cover (1) can be detachably mounted on the main cover (2), and the sealing mechanism (3) can be detachably transferred to the top cover (1) and surrounded by the main cover (2), so that when the top cover (1) and the main cover (2) rotate relative to each other, the sealing mechanism (3) is driven to rotate synchronously, and the synchronous rotation enables the sealing relationship between the sealing mechanism (3) and the main cover (2) to be switched, and the switching of the sealing relationship enables the direct drinking hole (21) provided on the main cover (2) to be exposed, or the straw (22) provided on the main cover (2) to be exposed;

[0035] The main cover (2) is provided with a through hole (23), and the top cover (1) comprises an end portion (11) and an embedded portion (12) connected to the end portion (11), so that when the top cover (1) is detachably assembled on the main cover (2), the end portion (11) covers the main cover (2), and the embedded portion (12) passes through the through hole (23) and is surrounded by the main cover (2).

[0036] Optionally, it further comprises: a top cover rotating part (4), wherein the top cover rotating part (4) is embedded in the embedding part (12), and the embedding part (12) can rotate around the top cover rotating part (4), so that the top cover (1) and the main cover (2) can rotate relative to each other.

[0037] To this end, by embedding the top cover rotating part (4) in the embedded part (12), the stability of the top cover (1) during the rotation process can be ensured, and the problem of reduced sealing performance or splashing of beverages due to uneven or unstable rotation can be avoided. In addition, during use, the user only needs to gently rotate the top cover to achieve synchronous rotation of the sealing mechanism, thereby switching the sealing state, which greatly reduces the difficulty of use for the user and improves convenience. Furthermore, due to the design of the top cover rotating part (4) and the embedded part (12), the accurate alignment and close contact of the sealing mechanism can be ensured, thereby improving the reliability of the sealing performance. Whether it is direct drinking or using a straw, a good sealing effect can be maintained. The design of the rotating mechanism makes the connection between the top cover and the main cover tighter, reduces the space for beverage residue and dirt accumulation, and is convenient for users to clean and maintain. Finally, the design of the rotating part can be adjusted according to the overall design and functional requirements of the product. For example, by changing the shape and size of the rotating part, it can adapt to cups of different sizes and shapes, providing more diverse product choices.

[0038] Optionally, the cup cover further comprises: a tea bin (5), wherein the tea bin (5) is detachably fixed below the top cover rotating portion (4), so that the tea bin (5) can be accommodated in the inner cavity of the cup body (0).

[0039] To this end, by integrating the tea bin (5) in the cup cover, the user can directly brew tea leaves or other types of tea beverages in the cup body (0), so that the cup cover is not just a simple sealing device, but a tool for making simple tea drinks. Furthermore, the detachable design of the tea bin (5) means that the user can easily remove the tea bin for cleaning, avoiding the accumulation of tea residues inside the cup cover, and keeping the cup cover hygienic and clean. In addition, the setting of the tea bin (5) allows the user to better control the concentration and taste of the tea beverage when drinking, and the user can adjust the amount of tea and brewing time according to personal taste to obtain an ideal tea beverage. Finally, the design of the tea bin (5) allows the tea leaves to be safely stored in the cup cover, reducing the risk of the tea leaves being scattered or squeezed. The user can conveniently carry the cup and enjoy fresh tea drinks at any time, whether in the office, outdoor activities or travel. Moreover, since the tea bin (5) is integrated in the cup cover, this design saves space for storing additional tea containers.

[0040] Optionally, the sealing mechanism (3) comprises a rotating member (31) and a sealing member (32); the rotating member (31) is mounted on the top cover (1), and the sealing member (32) is mounted on the rotating member (31), so that when the top cover (1) and the main cover (2) rotate relative to each other, the rotating member (31) is driven to rotate synchronously, and the sealing member (32) is driven to rotate synchronously, so that the sealing relationship between the sealing mechanism (3) and the main cover (2) can be switched.

[0041] To this end, a tighter and more reliable sealing effect can be achieved by combining the rotating member (31) and the sealing member (32). The sealing member (32) can be made of a soft and durable material, such as silicone or other synthetic rubber, to ensure that good sealing properties can be maintained under different conditions. In addition, when the top cover (1) and the main cover (2) rotate relative to each other, the synchronous rotation of the rotating member (31) and the sealing member (32) enables the sealing mechanism (3) to flexibly switch the sealing state. This design allows the user to easily open or close the direct drinking hole or the straw hole as needed, providing a better user experience. Furthermore, the user only needs to rotate the top cover (1) to switch the sealing mechanism (3), which is simple and intuitive to operate. This design reduces the learning cost and operating difficulty of the user during use. Moreover, the design of the rotating member (31) and the sealing member (32) allows the sealing mechanism (3) to maintain good performance after long-term use. The rotating member (31) can be made of a hard material to provide sufficient support and durability, and the replaceability of the sealing member (32) also means that it can be easily replaced after being worn or damaged, thereby extending the service life of the entire cup cover system. Finally, since the rotating member (31) and the sealing member (32) are assembled together, the user can easily disassemble and clean these parts to keep the cup cover clean and hygienic, while also facilitating the inspection and replacement of worn parts. The design of this sealing mechanism (3) can adapt to cups of different shapes and sizes, so that the same design can be applied to a variety of different types of cups, thereby increasing the versatility and market adaptability of the product.

[0042] Optionally, the rotating member (31) is assembled on the top cover (1) by means of concave-convex snap-fitting, so that a rigid connection relationship is formed between the top covers (1), and based on the rigid connection relationship, the top cover (1) can be detachably assembled on the main cover (2).

[0043] To this end, the concave-convex snap-fit ​​design provides a mechanical locking mechanism that can ensure that the connection between the rotating member (31) and the top cover (1) is both firm and stable. This rigid connection relationship helps to maintain consistency and reliability during the rotation operation, and avoids leakage or inconvenience in use caused by unstable connection. In addition, although a rigid connection is formed between the rotating member (31) and the top cover (1), this connection method still allows the top cover (1) to be detachably assembled on the main cover (2). This means that the user can easily disassemble and reassemble the top cover, which is convenient for daily cleaning and maintenance. Furthermore, the concave-convex snap-fit ​​design can effectively resist wear and tear during daily use and reduce loosening or damage of the connection caused by long-term use. This durable design helps to extend the overall service life of the cup cover. Finally, compared with complex mechanical connection or bonding processes, the concave-convex snap-fit ​​design is simpler and more economical in the manufacturing process. This design helps to reduce production costs while maintaining consistency in product quality. When using the cup cover, the user does not have to worry about the top cover accidentally loosening or falling off. This stable connection can provide a smoother and more confident use experience, especially when quickly rotating to open or close the sealing mechanism. In addition, this design allows the rotating member (31) and the top cover (1) to be used as a whole with other cup cover components (such as the main cover (2)), thereby enhancing the flexibility and adaptability of the design and being able to adapt to cups of different sizes and shapes. The rigid connection relationship ensures that during use, even if a certain external force is applied, the rotating member (31) and the top cover (1) will not accidentally separate, thereby ensuring safety during use.

[0044] Optionally, the top cover (1) comprises an embedding portion (12), the embedding portion (12) is provided with a first groove (121), the rotating member (31) is provided with a convex tooth (311), the first groove (121) and the convex tooth (311) form the concave-convex engagement, so that the rotating member (31) is assembled on the top cover (1) through the concave-convex engagement.

[0045] To this end, the concave-convex snap-fit ​​design between the first groove (121) and the convex tooth (311) ensures precise fit between the rotating member (31) and the top cover (1). This fit can reduce errors during assembly and improve the overall quality of the product. In addition, the concave-convex snap-fit ​​design provides a strong mechanical locking force, so that the assembly of the rotating member (31) on the top cover (1) is very stable. This connection method can effectively prevent the loosening or falling off of the components due to accidental collision or excessive rotation force during use. Furthermore, this design allows the rotating member (31) to be assembled to the top cover (1) through a simple insertion and snap-fit ​​action without the need for complex assembly tools or additional fixing elements. This not only simplifies the assembly process, but also reduces production costs. Furthermore, despite the stable connection, the concave-convex snap-fit ​​design allows the user to easily disassemble the rotating member (31) when necessary for cleaning, maintenance or replacement. This design improves the maintainability and user experience of the product, and, due to the mechanical stability of the concave-convex snap-fit ​​connection method, this design helps to improve the durability of the cup cover. Even during long-term use and repeated assembly / disassembly processes, the connection part is not easily damaged. This design can be applied to top covers and rotating parts of different sizes and shapes, thereby improving the adaptability and versatility of the design. This allows the same type of cup cover to be adapted to a variety of different cup designs, thereby increasing the market competitiveness of the product. The stable concave-convex snap-fit ​​connection ensures that during use, even if a certain external force is applied, the rotating part (31) will not accidentally detach from the top cover (1), thereby ensuring the safety of the use process.

[0046] Optionally, the rotating member (31) comprises: a convex tooth setting portion (312), a rotating ring (313), and a rotating arm (314); the rotating ring (313) is connected to the rotating arm (314) and surrounds the convex tooth setting portion (312); the convex tooth (311) is provided on the convex tooth setting portion (312); the rotating arm (314) is provided with a notch (3141); the sealing member (32) is provided with a protrusion (321); the protrusion (321) cooperates with the notch (3141) to assemble the sealing member (32) on the rotating arm (314); the rotating ring (313) cooperates with the top cover (1) to squeeze the straw (22) and form a space for accommodating the straw (22), so that when the sealing relationship is switched, the direct drinking hole (21) provided on the main cover (2) can be exposed, or the straw (22) provided on the main cover (2) can be exposed.

[0047] To this end, the design of the rotating member (31) allows the position of the sealing member (32) to be controlled by a rotating action, thereby achieving the covering or uncovering of the direct drinking hole (21) or the straw (22). This design provides a simple and intuitive way to switch the drinking mode of the cup cover. Furthermore, the cooperation between the notch (3141) on the rotating arm (314) and the protrusion (321) on the sealing member (32) ensures the stable assembly and precise position control of the sealing member. This precise cooperation helps to improve the sealing effect and prevent leakage. In addition, the design of the rotating ring (313) allows the straw (22) to be effectively squeezed and fixed during the rotation process, forming a stable accommodation space. This fixing method helps to prevent the straw from moving or falling off during use. Furthermore, the design of the rotating member (31) can not only control the opening and closing of the direct drinking hole, but also adapt to the use of the straw. This versatility allows the cup cover to meet the usage requirements of different users, increasing the applicability and attractiveness of the product. Finally, the design of the convex teeth (311) allows the user to switch the sealing state of the cup cover by a simple rotation action, whether opening the direct drinking hole or using a straw, which can be easily achieved. In addition, the structural design of the convex tooth setting part (312), the rotating ring (313) and the rotating arm (314) takes into account the durability of long-term use, and can maintain stable performance even under frequent use. Finally, since the design of the rotating member (31) and the sealing member (32) allows them to be easily disassembled, the user can easily clean and maintain them to keep the cup cover hygienic and extend its service life.

[0048] Optionally, the rotating member (31) is a rotary valve structure, and the sealing member (32) is a sealing sheet that matches the rotating arm (314) in shape.

[0049] To this end, in the design of the cup cover, the rotating member (31) is designed as a rotary valve structure, and the sealing member (32) is designed as a sealing sheet that matches the rotating arm (314) in form, which can achieve the following technical benefits:

[0050] 1. The rotating member (31) of the rotary valve structure can accurately control the flow of the fluid. Through the rotation operation, the user can easily switch the sealing state of the cup cover to open and close the direct drinking hole or the straw.

[0051] 2. The shape matching design of the sealing sheet (32) and the rotating arm (314) ensures that the sealing sheet can fit tightly against the rotating arm during the rotation process, thereby providing a good sealing effect. This design helps prevent liquid leakage and ensures the sealing performance of the cup cover during use.

[0052] 3. The design of the rotary valve structure allows the user to switch the sealing state with just a simple rotation. This operation method is simple and intuitive, and easy for users to understand and use.

[0053] 4. The design of the rotary valve structure and the sealing piece takes into account the durability of long-term use. The materials and structural design used can effectively resist wear and tear, thereby extending the service life of the cup cover.

[0054] 5. Since the rotary valve structure and sealing sheet can be easily disassembled, users can easily clean and maintain them to keep the cup cover hygienic and in good performance.

[0055] 6. This design can adapt to cups of different sizes and shapes, providing a universal solution so that the same type of cup lid can be adapted to a variety of different cup designs, increasing the market adaptability of the product.

[0056] Optionally, the cup cover further comprises a pre-tightening ring (6), wherein the pre-tightening ring (6) is connected to the top cover (1) so as to provide a pre-tightening force for the sealing mechanism (3) when the top cover (1) is detachably assembled on the main cover (2).

[0057] To this end, the pre-tightening ring (6) provides a pre-tightening force for the sealing mechanism (3), thereby helping to ensure close contact between the sealing member (32) and the main cover (2), thereby reducing the risk of liquid leakage. This pre-tightening force can improve the sealing performance of the cup cover under various use conditions. In addition, the presence of the pre-tightening ring (6) not only enhances the sealing effect, but also improves the structural stability between the top cover (1) and the main cover (2). This stability helps to reduce the possibility of accidental opening or damage during transportation or use. Furthermore, the design of the pre-tightening ring (6) makes it easier to assemble the top cover (1) on the main cover (2) and maintain an appropriate pre-tightening force. This simplified assembly process can improve production efficiency and reduce manufacturing costs. Finally, when the user uses the cup cover, the pre-tightening ring (6) can ensure that the sealing mechanism (3) always maintains an appropriate pre-tightening state, thereby providing a consistent use experience. The user does not need to worry about whether the cup cover is correctly installed or whether the seal is effective, and can use it with more peace of mind. In addition, the design of the pre-tightening ring (6) allows the user to easily remove the top cover (1) for easy cleaning and maintenance. This easy-to-maintain design helps to keep the cup cover clean and prolong its service life. In addition, the design of the preload ring (6) takes into account the durability of long-term use, and the material and structural design used can effectively resist wear and deformation, thereby maintaining the stability of the preload force and prolonging the overall service life of the cup cover.

[0058] Optionally, the pre-tightening ring (6) is connected to the top cover (1) through concave-convex fit.

[0059] Optionally, the top cover (1) comprises an embedding portion (12), the embedding portion (12) is provided with a second groove (122), the preload ring (6) is provided with a first undercut (61), the first groove (121) and the first undercut (61) form a concave-convex fit, so that the preload ring (6) is connected to the top cover (1) through the concave-convex fit.

[0060] To this end, the tight connection between the preload ring (6) and the top cover (1) is ensured by the concave-convex matching design. This mechanical connection method performs well in resisting wear and impact in daily use, thereby ensuring the long-term stability of the connection. Furthermore, the accurate matching of the first groove (121) and the undercut (61) can ensure the correct positioning of the preload ring (6) during the assembly process, avoiding the degradation of the sealing performance or structural instability caused by improper assembly. In addition, the concave-convex matching design allows the preload ring (6) to be assembled to the top cover (1) by simple insertion and snap-in action, and is also easy to disassemble, which helps to improve production efficiency and reduce maintenance costs. Finally, due to the mechanical stability of the concave-convex matching connection method, this design helps to improve the durability of the cup cover. Even during long-term use and repeated assembly / disassembly processes, the connection part is not easily damaged. In addition, the design of the preload ring (6) allows the user to easily disassemble the top cover (1) for easy cleaning and maintenance, thereby maintaining the hygiene and good performance of the cup cover.

[0061] Optionally, the preload ring (6) is provided with an elastic portion (62), and when the first groove (121) and the first undercut (61) form the concave-convex fit, the elastic portion (62) contacts the sealing mechanism (3) to provide a preload force for the sealing mechanism (3). The elastic portion (62) is, for example, a spring.

[0062] To this end, the elastic part (62), such as a spring, can provide a stable pre-tightening force for the sealing mechanism (3) when the first groove (121) and the first undercut (61) form a concave-convex fit. This pre-tightening force helps to maintain close contact between the sealing mechanism and the main cover (2), thereby improving the sealing performance. Furthermore, the design of the elastic part (62) allows it to deform when subjected to external force, thereby adapting to different sealing pressures. This adaptive ability ensures that the sealing mechanism can maintain a good sealing effect even when the pressure changes or the cup cover size is slightly different. Moreover, the addition of the elastic part (62) can absorb and disperse the impact force generated by accidental impact or pressure change to a certain extent, thereby protecting other parts of the cup cover from damage. Finally, the design of the elastic part (62) makes the pre-tightening ring (6) more flexible during assembly and disassembly, and the user can more easily install and remove the cup cover while maintaining the correct position and pre-tightening state of the sealing mechanism. Furthermore, the elastic part (62) is usually made of durable materials, such as stainless steel or high-strength plastic, which have good elasticity and wear resistance, helping to ensure the reliability and stability of the pre-tightening ring (6) in long-term use. And because the pre-tightening ring (6) and the elastic part (62) can be easily disassembled, the user can conveniently clean and maintain them, so as to keep the cup cover hygienic and extend its service life.

[0063] Optionally, the undercuts (61) are in plurality and are arranged around the inner periphery of the pre-tightening ring (6), and the elastic portions (62) are in plurality and are arranged around the outer periphery of the pre-tightening ring (6), so that the undercuts (61) and the elastic portions (62) are arranged in an inner-outer staggered arrangement, and the inner-outer staggered arrangement enables the first groove (121) and the first undercut (61) to form the concave-convex fit, and the elastic portion (62) contacts the sealing mechanism (3) when the first groove (121) and the first undercut (61) form the concave-convex fit to provide a pre-tightening force for the sealing mechanism (3).

[0064] To this end, the surrounding arrangement of the plurality of undercuts (61) and the elastic portion (62) can evenly distribute the preload force over the entire circumference of the preload ring (6), which helps to ensure that the contact between the sealing mechanism (3) and the main cover (2) is more uniform, thereby improving the sealing performance. Furthermore, the undercuts (61) and the elastic portion (62) arranged in a staggered manner inside and outside can provide support in all directions, thereby enhancing the stability of the cup cover structure. This stability helps to reduce deformation or damage caused by pressure or impact during use. In addition, the arrangement of the plurality of undercuts (61) and the elastic portion (62) makes the assembly process more precise and reliable. This design can reduce the risk of improper assembly and ensure that the expected sealing effect can be achieved each time the assembly is performed.
