The movable hook 6 is guided and installed inside the flip cover 2. The flip cover 2 also has a first elastic element 14 installed inside to maintain the latch 7 and the slot 8 engaged. The top of the flip cover 2 has a vertically pressable elastic button. By pressing the elastic button, the latch 7 disengages from the slot 8, thus opening the flip cover 2.

[0027] The card slot 8 is located inside the drinking port 5. A sealing part is provided in the internal channel of the drinking port 5 below the card slot 8. The flip cover 2 is closed by the engagement of the hook 7 with the card slot 8. The sealing plug 9 of the flip cover 2 cooperates with the sealing part of the drinking port 5 to seal the internal channel of the drinking port 5.

[0028] The flip cover 2 has an annular mounting groove 10 at its top. A downward-extending protruding ring 11 surrounds the button 15. The protruding ring 11 of the button 15 is slidably positioned within the annular mounting groove 10 of the flip cover 2. A second elastic element 12 is annular and located within the annular mounting groove 10, inside the protruding ring 11, providing elastic support for the button 15. A retaining cover 13 is connected to the top of the flip cover 2 to limit the upper limit position of the button 15. The retaining cover 13 has a central hole, through which the pressing part of the button 15 is exposed. The retaining cover 13 is connected to the top of the flip cover 2 via a snap-fit ​​mechanism. The bottom of the retaining cover 13 abuts against the top edge of the button 15, thus limiting the upper limit position of the button 15.

[0029] The movable hook 6 is slidably disposed within the flip cover 2 and can slide along the front-to-back direction of the flip cover 2. Under the elastic force of the first elastic element 14, the movable hook 6 is at its front limit position. The elastic button includes a button 15 arranged vertically and a second elastic element 12. The button 15 is slidably disposed on the top of the flip cover 2 and can be pressed vertically. Under the elastic force of the second elastic element 12, the button 15 is at its upper limit position. The bottom of the button 15 is provided with a pushing protrusion 16. The movable hook 6 has a pushing groove 17 for the pushing protrusion 16 to extend downward. The rear end face of the pushing protrusion 16 and the rear side wall of the pushing groove 17 are in inclined engagement. Pressing the button 15 downward, under the action of the inclined engagement between the pushing protrusion 16 and the pushing groove 17, converts the vertical movement into horizontal movement, thereby driving the movable hook 6 to move backward, causing the hook 7 of the movable hook 6 to disengage from the slot 8 of the drinking spout 5, thus opening the flip cover 2.

[0030] The bottom center of the flip cover 2 has a downwardly protruding mounting part 18. The mounting part 18 is a hollow structure with an internal cavity 19. The top of the cavity 19 of the mounting part 18 is an open end.

Support plates 20 are respectively provided on the left and right sides of the upper section of the cavity 19 of the mounting part 18, and the movable hook 6 is slidably supported by the two support plates 20. The hook part of the latch 7 is exposed from the avoidance groove 21 opened on the front side of the mounting part 18, and the sealing plug 9 is provided at the bottom of the mounting part 18. The drinking port 5 is a cylindrical drinking port 5 extending upward from the top of the connecting body 1. The mounting part 18 of the flip cover 2 is embedded in the internal channel of the drinking port 5. The sealing part of the internal channel of the drinking port 5 has a sealing step 22. The sealing plug 9 cooperates with the sealing step 22 of the drinking port 5 to achieve a seal.

[0031] Both the first elastic element 14 and the second elastic element 12 are springs.

[0032] When the flip cover 2 is closed, the hook 7 at the bottom of the movable hook 6 engages with the groove 8 inside the drinking port 5 of the connector 1. The sealing plug 9 of the flip cover 2 cooperates with the sealing part of the drinking port 5 to seal the internal channel of the drinking port 5.

[0033] When it is necessary to open the flip cover 2, press the button 15 down. Under the action of the inclined surface between the push protrusion 16 and the push groove 17, the moving hook 6 is pushed to move backward, so that the hook 7 of the moving hook 6 gradually disengages from the groove 8 inside the drinking port 5, the flip cover 2 is unlocked, and under the action of the torsion spring, the flip cover 2 automatically flips backward and upward, realizing the automatic opening of the flip cover 2. At this time, you can drink water through the drinking port 5.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
