The outer side of the bottom surface of the upper cover 9 is integrally connected with an annular extension portion 11. The annular extension portion 11 is provided with grooves on the outer walls on both sides of the opposite sides and is inserted with balls 12. When the balls 12 on both sides rotate with the upper cover 9, they are respectively moved into the relative positioning recessed holes 8.

[0027] Thus, by moving the upper cover 9, the lower cover 10 is driven to rotate, and the straw 3 rotates synchronously therewith. When the water inlet 7 and the water outlet 6 are connected, the water outlet 6 is opened to connect the straw 3 and the cup body. When the water inlet 7 and the water outlet 6 are misaligned, the other side of the bottom end of the straw 3 covers and seals the water outlet 6, which plays the role of closing the water outlet 6, thereby separating the straw 3 from the cup body. At this time, the balls 12 on both sides are respectively moved into the relative positioning recessed holes 8 to play a role of limiting.

[0028] In the utility model, the straw 3 includes an upper straight tube section 13, a pleated tube section 14 and a lower straight tube section 15 which are integrally connected in sequence from top to bottom. The upper straight tube section 13 and the pleated tube section 14 are exposed from the upper cover 9. Drinking water can be conveniently achieved by bending the pleated tube section 14 in any direction. An upper annular protrusion 16 and a lower annular protrusion 17 are integrally connected to the outer walls of the upper and lower ends of the lower straight tube section 15, respectively.

[0029] In the present utility model, the cross-section of the lower cover 10 is U-shaped, and the upper end of the outer edge of the lower cover 10 is fixedly connected to the lower edge of the annular extension portion 11, so as to achieve a fixed connection with the upper cover 9, and the inner edge of the lower cover 10 is bent inward to form an annular closing portion 22 with an L-shaped cross-section, and the inner edge of the annular closing portion 22 abuts against the outer side of the lower annular protrusion 17, so as to achieve the bottom of the straw 3 being pressed against the boss 5, and the upper edge of the annular closing portion 22 is fixedly connected to the bottom surface of the upper cover 9, so as to achieve a fixed connection with the upper cover 9.

[0030] In the utility model, an annular recessed groove is provided in the middle of the upper cover 9, and the upper annular protrusion 16 is sealed in the annular recessed groove, thereby achieving sealing.

[0031] In the utility model, the outer parts of the upper straight pipe section 13 and the pleated pipe section 14 are sheathed with a straw cap 18 .

[0032] Therefore, when drinking water, just pull off the straw cap 18; when not drinking water, just put on the straw cap 18, which is conducive to maintaining hygiene.

[0033] In the present invention, a paddle 19 is integrally connected to one side edge of the upper cover 9 to facilitate the upper cover 9 to be moved and rotated, and a fixing plate 20 is integrally connected to one side of the upper surface of the fixed cover body 1 .

[0034] Therefore, during the rotation of the upper cover 9, when the paddle 19 and the fixing plate 20 are in contact with each other, the water inlet 7 and the water outlet 6 are connected; when the paddle 19 and the fixing plate 20 are away from each other, the water inlet 7 and the water outlet 6 are misaligned.

[0035] In the present invention, an annular groove is provided on the bottom surface of the boss 5 and a connector 21 is clamped therein, so as to connect the water pipe extending into the cup body and then drink water.

[0036] The utility model is further described below in conjunction with the accompanying drawings:

[0037] When in use, the cup cover of the utility model can be rotatably opened and closed and is screwed on the cup mouth of the cup body through thread matching.

[0038] When drinking water, the upper cover is rotated by holding the paddle 19, which drives the lower cover 10 to rotate, and the straw 3 rotates synchronously therewith. When the paddle 19 is in contact with the fixing plate 20, the water inlet 7 is connected with the water outlet 6, the water outlet 6 is opened, and the straw 3 and the water guide pipe are connected. At this time, drinking water can be achieved by sucking on the straw 3.

[0039] When not drinking water, the upper cover is rotated by holding the paddle 19, which drives the lower cover 10 to rotate, and the straw 3 rotates synchronously therewith. When the paddle 19 is away from the fixing plate 20, the water inlet 7 is misaligned with the water outlet 6, and the other side of the bottom end of the straw 3 covers and seals the water outlet 6, closing the water outlet 6, thereby isolating the straw 3 from the cup body, and preventing the hot water in the cup from gushing out through the straw and causing unnecessary trouble.

[0040] During this process, the balls 12 on both sides are respectively moved into the relative positioning recessed holes 8 to play a limiting role.

[0041] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
