The waterproof rubber pad 17 between the connecting ring 16 will be deformed to a certain extent under the force, which has a sealing effect on the cup mouth. A pressure relief hole 15 is provided above the cup cover 1, and the pressure relief hole 15 is blocked by a sealing plug 19 when the water cup is in use. The lower pressure plate 22 can be moved downward by rotating the rotating rod 21, so that the lower pressure plate 22 continuously presses against the top of the sealing plug 19 to prevent the sealing plug 19 from falling off. When the lid of the cup 1 cannot be opened smoothly due to pressure problems inside the cup 1, the fastening cover 6 can be rotated to remove the fastening cover 6 from the fastening cylinder 14, and then the sealing plug 19 can be pulled out by pulling the lifting tab 20. At this time, the pressure inside the water cup 1 returns to normal and the cup can be opened smoothly.
