[0061] In this embodiment, an annular groove 42 is formed on the sealing seat 4, and the sealing member 3 has a horizontal part 31 and an L-shaped part 32. The horizontal section of the L-shaped part 32 is located in the annular groove 42 to prevent the sealing member 3 from coming off the sealing seat 4 or from being displaced (non-deformed).

[0062] In this embodiment, a raised ring 33 extends from the lower surface of the sealing element 3, and a limiting flange 43 is formed at the edge of the sealing seat 4. The sealing rib 19 of the main cover 1 is located between the raised ring 33 of the sealing element 3 and the limiting flange 43 of the sealing seat 4. Reliable sealing is achieved through the sealing rib 19, the raised ring 33, and the limiting flange 43.

[0063] In this embodiment, a positioning flange 44 is formed at the center of the sealing seat 4, and a positioning ring 34 is formed on the lower surface of the sealing member 3, which is fitted around the positioning flange 44. The positioning flange 44 ensures that the upper surface of the sealing member 3 remains horizontal and does not collapse.

[0064] In this embodiment, a sliding groove 13 is formed on the main cover 1, the sliding piece 2 cooperates with the sliding groove 13, and the through groove 12 restricts the two extreme positions of the sliding component.

[0065] In this embodiment, the slider 2 is engaged with the main cover 1, and two first engaging portions 18 are formed on the main cover 1, while two second engaging portions 22 are formed on the slider 2.

[0066] In this embodiment, the pitch of the sealing seat 4 and the rotating component 5 is designed such that the lifting height of the sealing seat 4 is 0.5mm-2mm for every 90° rotation of the rotating component 5, with about 1mm being more ideal. During operation, simply rotate 90°.

[0067] In this embodiment, a sliding positioning part 21 is formed on the sliding piece 2, and a sealing positioning structure and a water outlet positioning structure are formed between the sliding piece 2 and the main cover 1. A sealing positioning groove 15 and a water outlet positioning groove 16 are formed on the main cover 1. The cross-sections of the positioning part, the sealing positioning groove 15 and the water outlet positioning groove 16 are all arc-shaped.

[0068] In this embodiment, a rotation positioning structure is formed between the rotating member 5 and the sliding cover. The rotation positioning structure includes a plurality of rotation positioning grooves 26 formed on the sliding piece 2 and a rotation positioning part 52 formed on the rotating member 5.

[0069] In this embodiment, the sliding assembly further includes an operating knob 6 fitted onto the rotating member 5; the operating knob 6 and the rotating member 5 are engaged and prevented from detaching; the operating knob 6 and the rotating member 5 form an anti-rotation structure; the operating knob 6 is a notched cylindrical shape, and an indicator mark 27 is formed on the sliding plate 2. In the sealed state and / or water outlet state, the indicator mark 27 is located in the notch of the operating knob 6. There are two indicator marks 27, used to indicate the rotation direction. In this embodiment, the operating knob 6 and the rotating member 5 are assembled; in other embodiments, the operating knob 6 and the rotating member 5 can also be a single integral part.

[0070] In this embodiment, the sealing element 3 has a through hole for the rotating element 5 to pass through, and the sealing element 3 also has an air inlet notch 35 communicating with the through hole. The sliding cover has a horizontal air inlet groove 23. The main cover 1 has a vertical air inlet groove 17. External gas enters the cup body in sequence through the horizontal air inlet groove 23, the vertical air inlet groove 17 and the air inlet notch 35, ensuring smooth air intake (when the cup cover is tilted, the end of the cup cover near the water outlet 11 of the main cover 1 may be completely or partially blocked, resulting in poor air intake at that point).

[0071] In this embodiment, see Figure 1 and Figure 3 In the sealed state, the seal 3 is located directly below the water outlet 11, and the sealing seat 4 and the rotating part 5 are tightened. The seal 3 seals the water outlet 11 and the through groove 12. At this time, the indicator mark 27 "OPEN" (which also includes a triangle indicating the direction) on the slider 2 is in the notch of the operating knob 6. When you need to drink water, see... Figure 2 and Figure 4The operating knob 6 can be rotated clockwise (when viewed from above) to rotate the operating knob 6 and the operating component 90°. The two rotation positioning parts 52 on the rotating component 5 are positioned from the two rotation positioning grooves 26 on the slide plate 2 into the other two rotation positioning grooves 26. During the rotation, the sealing seat 4 and the sealing element 3 cannot rotate due to the restriction of the two anti-rotation protrusions 14 on the main cover 1. The sealing seat 4 and the sealing element 3 will drop a certain distance (about 1mm). At this time, the sealing element 3 is not compressed or the compression is very small, and the slide plate 2 can slide relatively easily. At this time, push the operating knob 6 to make the entire sliding assembly slide from left to right. The sliding positioning part 21 of the slide plate 2 moves from the sealing positioning groove 15 to the water outlet positioning groove 16, and the water outlet 11 of the main cover 1 is opened. At this time, water can be drunk, and the slide plate 2 assembly is positioned and will not move. After drinking, the operation can be reversed to open the water outlet 11. Figure 4 The water outlet state returned to Figure 2 The sealed state.

[0072] In this embodiment, when disassembly and cleaning are required, simply rotate the operating knob 6 counterclockwise until the rotating part 5 is completely separated from the sealing seat 4, and the sealing seat 4 (and the sealing part 3 on it) and the rotating part 5 (and the operating knob 6 on it) can be separated from the main cover 1.

[0073] The beneficial effects of the rotary sealing sliding plate 2 direct drinking cup lid of this utility model embodiment 1 are as follows: When the sealing member 3 is located directly below the water outlet 11 and the sealing seat 4 and the rotating member 5 are tightened, the sealing member 3 seals the water outlet 11 and the through groove 12, and the sliding component is in a sealed state. When the projection of the sealing member 3 and the water outlet 11 on the horizontal plane is misaligned and the sealing seat 4 and the rotating member 5 are loosened, the sealing member 3 releases the seal on the water outlet 11 and the through groove 12, and the sliding component is in a water outlet state. In use, by operating the rotating sealing member 3, the sealing seat 4 and the sealing member 3 on the sealing seat 4 are raised and lowered, and the sliding component is slid, realizing the switching of the sliding component between the sealed state and the water outlet state; the operation method is different from the existing ones; although compared with the existing direct drinking cup lids that only slide, the solution of this embodiment requires rotation and sliding, the sealing performance is good, and it is used to seal when accommodating boiling water; the operation is not laborious; disassembly is easy and cleaning is convenient.

[0074] The above description is merely a specific embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the above specific embodiments.
