Existing rotating cup lids have the problem of unreliable sealing at the drinking spout.
A rotating cup lid was designed, including a rotating component, a lid body, and a sealing component. The rotation of the rotating component causes the sealing component to slide within the lid body. The first elastic rubber ring on the sealing component abuts against or separates from the lid body, thereby blocking or opening the drinking channel and enhancing the sealing performance.
The improved sealing of the lid ensures that liquid leakage is prevented when closed and makes drinking easier when open, thus enhancing the user experience.

[0023] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.
[0024] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.
[0025] The cup includes a cup body 2 and a cup lid 1, with the cup lid 1 threadedly connected to the cup body 2.
[0026] This embodiment mainly describes the structure of the cup lid, as follows:
[0027] like Figure 1 , Figure 2 As shown, the rotating cup lid has a second elastic rubber ring 5 on the lid 1. The edge of the cup body 2 abuts against the second elastic rubber ring 5. When the lid 1 and the cup body 2 are tightened by the threaded connection, the second elastic rubber ring 5 is compressed. Under the elastic force of the second elastic rubber ring 5, the sealing between the lid 1 and the cup body 2 is improved.
[0028] like Figure 3 As shown, the cup lid 1 includes a lid body 4, a rotating part 3, and a sealing part 9. The lid body 4 is provided with an air hole 14 for balancing the air pressure inside and outside the cup body 2 when drinking water and a drinking channel 13. A cavity 20 is opened at the bottom of the lid body 4. The sealing part 9 is disposed inside the lid body 4 and slides in fit with the lid body 4. The rotating part 3 is disposed inside the lid body 4 and is threadedly connected to the sealing part 9. By rotating the rotating part 3, the sealing part 9 is driven to slide inside the lid body 4 to block or open the cavity 20, so as to open or close the drinking channel 13.
[0029] like Figure 4 , Figure 5As shown, the cover 4 is provided with an insertion hole 19, and the outer wall of the insertion hole 19 is provided with a slot 11. There are two slots 11, and the two slots 11 have different widths. The sealing part 9 is provided with a plug 10. The width and number of the plug 10 correspond to those of the slots 11. There are two plugs 10. The two plugs 10 are respectively arranged in a "T" shape and an "I" shape, which makes it easy for users to distinguish them and prevents users from assembling the sealing part 9 in reverse.
[0030] The rotating part 3 is inserted into the cover 4 from the other end of the insertion hole 19 and is connected to the sealing part 9 by threads. Specifically, the rotating part 3 is provided with internal threads and the sealing part 9 is provided with external threads. Through the meshing of the internal threads and external threads, the rotating part 3 is rotatably mounted on the sealing part 9.
[0031] like Figure 5 As shown, a first protruding edge 12 is provided on the inner side wall of the socket 19, and a second protruding edge 7 is provided on the outer side wall of the rotating part 3. The first protruding edge 12 and the second protruding edge 7 abut against each other, and the second protruding edge 7 is located below the first protruding edge 12. When the user moves the rotating part 3 to make it rotate, the first protruding edge 12 restricts the second protruding edge 7 from sliding upward due to the rotation of the internal thread of the rotating part 3. At the same time, by restricting the second protruding edge 7, the rotating part 3 is limited to rotate within the socket 19.
[0032] like Figure 6 As shown, the rotating part 3 is provided with a protrusion 6, and the inner sidewall of the insertion hole 19 is provided with a sliding groove 17. The protrusion 6 slides in the sliding groove 17 as the rotating part 3 rotates. The sliding groove 17 restricts the rotation range of the rotating part 3 in the insertion hole 19 through the protrusion 6. Preferably, the rotation range of the rotating part 3 in the insertion hole 19 is 0°~90°.
[0033] Two protrusions 18 are provided in the slide groove 17. The two protrusions 18 are respectively located at both ends of the slide groove 17. The protrusions 18 and the ends of the slide groove 17 form a closed groove 15 and an open groove 16, respectively. The closed groove 15 and the open groove 16 limit the position of the protrusion 6 in the slide groove 17, so that the rotating part 3 is rotated due to accidental contact, causing an accident.
[0034] In summary, the cup lid has two states: open and closed. Figure 7As shown, when the cup lid 1 is in the closed state, the rotating part 3 does not rotate. The protrusion 6 on the rotating part 3 is located in the closed groove 15 in the slide groove 17. The internal thread on the rotating part 3 is fully engaged with the external thread on the sealing part 9. The lid 4 abuts against the sealing part 9. Specifically, the sealing part 9 is provided with an annular groove, and a first elastic rubber ring 8 is provided in the annular groove. The lid 4 abuts against the first elastic rubber ring 8, causing the first elastic rubber ring 8 to undergo elastic deformation. Under the elastic force of the first elastic rubber ring 8, the sealing part 9 seals the cavity 20 at the bottom of the lid 4, preventing the liquid in the cup 2 from flowing into the cavity 20, thus increasing the sealing between the sealing part 9 and the lid 4.
[0035] like Figure 8 As shown, when the cup lid 1 is in the open state, the rotating part 3 rotates 90° counterclockwise, causing the protrusion 6 on the rotating part 3 to rotate from the closed groove 15 to the open groove 16. Because the inner side wall of the insertion hole 19 is provided with a first protruding edge 12 and the outer side wall of the rotating part 3 is provided with a second protruding edge 7, and the second protruding edge 7 is located below the first protruding edge 12, the first protruding edge 12 limits the rotating part 3 from sliding upward due to rotation by limiting the second protruding edge 7. The rotating part 3 drives the sealing part 9 to rotate synchronously through the internal and external threads. The internal thread on the rotating part 3 separates from the external thread on the sealing part 9, the sealing part 9 slides downward, the lid 4 separates from the first elastic rubber ring 8, and the sealing part 9 is separated from the cavity 20. The water in the cup body 2 can flow into the drinking channel 13 through the cavity 20 from the separation point between the lid 4 and the first elastic rubber ring 8, making it convenient for the user to drink water.
