[0021] Please refer to Figure 1 , Figure 2 , Figure 3 The rotating structure of the thermos cup lid includes: an upper cover 1, an inner cover 3 movably connected to the inner ring 6 of the upper cover 1, the upper cover 1 including the inner ring 6, the top of the inner ring 6 of the upper cover 1 extending outward to form an outer ring 5, the inner ring 6 of the upper cover 1 being hollow inside, a water outlet 19 provided at the connection between the outer ring 5 and the inner ring 6 of the upper cover 1, an outer cover 2 being fitted over the inner ring 6 of the upper cover 1, the outer cover 2 being hollow inside, a retaining strip 21 provided inside the outer cover 2, a retaining groove I 14 being opened on the outer side of the bottom of the inner ring 6 of the upper cover 1, the retaining groove I 14 of the upper cover 1 and the retaining strip 21 of the outer cover 2 being connected, and the upper cover 1 and the outer cover 2 being able to rotate relative to each other after connection.

[0022] The upper cover 1 has a chamfered lower side of the slot I14 to facilitate the insertion of the outer cover 2. The upper end of the locking strip 21 of the outer cover 2 has a chamfered upper end to facilitate the insertion of the slot I14. The locking strip 21 of the outer cover 2 is spiral-shaped, and the water outlet 19 is annular.

[0023] The inner cover 3 is hollow inside and closed at the top. The top of the inner cover 3 has a support portion 18 extending outward, which is used to prevent the inner cover 3 from tilting.

[0024] The inner ring 6 of the upper cover 1 is provided with a guide post I7. The outer surface of the inner cover 3 is provided with a spiral groove 12. The guide post I7 is connected to the spiral groove 12 of the inner cover 3. The guide post I7 rotates along the spiral groove 12 of the inner cover 3. A guide groove I11 is provided above the spiral groove 12. The guide groove I11 corresponds to the guide post I7 of the upper cover 1 in size and position. The guide groove I11 guides the guide post I7 to be inserted into the spiral groove 12. The upper end of the guide groove I11 has a chamfer to facilitate the insertion of the guide post I7.

[0025] The bottom of the outer ring 5 of the upper cover 1 abuts against the top of the outer cover 2. The top of the outer cover 2 extends outward to form a retaining ring I8. The retaining ring I8 of the outer cover 2 fits into the bottom of the outer ring 5 of the upper cover 1. The top of the outer cover 2 extends inward to form a retaining ring II20. A sealing ring is provided between the retaining ring II20 of the outer cover 2 and the inner ring 6 of the upper cover 1 for waterproofing.

[0026] The bottom of the inner wall of the outer cover 2 is provided with a guide post II10, and the outer side of the bottom of the inner cover 3 is provided with a guide groove II17. The guide post II10 of the outer cover 2 and the guide groove II17 of the inner cover 3 are both set perpendicular to the thermos cup. The guide post II10 of the outer cover 2 and the guide groove II17 of the inner cover 3 are corresponding in size and position.

[0027] The outer cover 2 has threads on its outer side and is threaded to the mouth of the thermos cup. A sealing ring is fitted around the bottom of the outer cover 2 to seal the mouth and lid of the thermos cup.

[0028] The bottom of the inner cover 3 is snapped into the bottom cover 4. The bottom cover 4 is hollow inside and closed at the bottom. The bottom of the inner wall of the inner cover 3 is provided with a locking foot 13. The top of the bottom cover 4 is provided with a locking groove II 16. The locking groove II 16 is spiral-shaped. The locking foot 13 of the inner cover 3 is snapped into the locking groove II 16 of the bottom cover 4 for connection. A sealing ring is provided below the connection between the locking foot 13 of the inner cover 3 and the locking groove II 16 of the bottom cover 4, so that the bottom cover 4 and the inner cover 3 form an integral sealed structure. The bottom of the bottom cover 4 extends outward to form a connecting part 15. A sealing ring is provided at the abutment between the connecting part 15 of the bottom cover 4 and the inner cover 3 for waterproofing.

[0029] When installing the rotating structure of the thermos cup lid of this utility model, the bottom cover 4 and the inner cover 3 are connected by the clip 13 and the groove II 16 to form an integral sealing structure. The top cover 1 and the outer cover 2 are connected by the groove I 14 and the clip 21 to form a structure that can rotate with each other. The outer cover 2 and the inner cover 3 are connected by the guide post II 10 and the vertical guide groove II 17 to form a structure that can move up and down. After connection, the sealing ring of the bottom cover 4 connection part 15 presses against the lower edge of the outer cover 2. The top cover 1 and the inner cover 3 are connected by the guide post I 7 along the guide groove I 11 and the spiral groove 12, forming a structure in which the guide post I 7 rotates and moves along the spiral groove 12.

[0030] When in use, screw the entire lid into the cup. The outer thread of the outer lid 2 connects to the cup rim. When pouring water, rotate the top lid 1, causing the guide post I7 of the top lid 1 to move along the spiral groove 12 of the inner lid 3. Since the cup and the outer lid 2 are fixedly connected, the top lid 1 and the outer lid 2 cannot move up or down. When the guide post I7 of the top lid 1 moves along the spiral groove 12 of the inner lid 3, it pushes the inner lid 3. The inner lid 3 drives the bottom lid 4 to move downward along the guide post II 10. After the sealing ring of the bottom lid 4 connection part 15 leaves the lower edge of the inner lid 3, tilt the cup. The tea can flow out through the gap between the inner lid 3 and the outer lid 2 to the water outlet 19 of the top lid 1 and then be poured out. When you need to close the cup after pouring the tea, rotate the top lid 1 in the opposite direction. The guide post I7 of the top lid 1 moves in the opposite direction along the spiral groove 12 of the inner lid 3, causing the inner lid 3 and the bottom lid 4 to move upward along the guide post II 10. The sealing ring of the bottom lid 4 connection part 15 is tightly attached to the lower edge of the inner lid 3, forming a seal to prevent the tea from overflowing.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various changes and modifications can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
