[0028] like Figures 1-7 As shown, a screw-less water cup includes a cup body 1, a lid 2 for closing the cup body 1 and a pressing block 3 installed on the lid 2, the lid 2 is provided with a movable channel 4 extending downward and open at both ends, and the pressing block 3 is movably installed in the movable channel 4; a sealing component 5 is provided at the lower end of the lid 2, the movable channel 4 extends downward and passes through the sealing component 5, a connecting portion 6 is provided between the sealing component 5 and the movable channel 4, and the pressing block 3 is movably installed at the lower end of the lid 2 through the connecting portion 6; a reset component 7 linked to the pressing block 3 is provided in the lid 2, and a locking portion 34 is provided between the sealing component 5 and the reset component 7. The lid 2 includes an open state and a closed state. In the closed state, the lid 2 is manually pressed down on the cup body 1, which drives the sealing member 5 to deform and generate wrinkles. The wrinkles of the sealing member 5 are engaged with the inner wall of the cup body 1. The diameter of the wrinkled sealing member 5 increases and is tightly engaged with the inner wall of the cup body 1, forming a threadless engagement of the lid 2 and also achieving a sealing effect. When the lid 2 is pressed down, the locking portion 34 is locked to prevent the wrinkled sealing member 5 from being reset by its own rebound force. In the open state, the pressing block 3 is manually pressed down, which drives the reset member 7 to move horizontally to release the lock of the locking portion 34. At this time, the wrinkled sealing member 5 rebounds, and the lid moves upward due to the rebound force of the sealing member 5. At this time, the lid 2 can be lifted up to open. There is no need to open the lid by screwing. The lid 2 can be locked by pressing down and unlocked by pressing the pressing block 3. The operation is relatively simple and convenient. It can be completed with one hand, which meets the convenience of user use.

When the pressing block 3 is pressed, the pressing block 3 touches the movable column 13 and displaces it downward to open the sealing groove 12, so that the air outside can enter the cup body 1 through the gas return groove 12 to balance the air pressure inside and outside. After the gas is discharged, the movable column 13 is reset by the spring, and the sealing member 14 re-closes the gas return groove 12.
[0032] The two sides of the inner wall of the mounting seat 8 are provided with longitudinal guide columns 15, and the two sides of the movable column 13 are provided with guide grooves 16 matched with the guide columns 15. When the movable column 13 is displaced upward and downward, the guide columns 15 move in the guide grooves 16, which are used for limiting the movable column 13 to prevent it from being tilted and also guide the movement track of the movable column 13.
[0033] The connecting part 6 comprises a plurality of annularly distributed connecting grooves 17 in the inner wall of the movable channel 4 and a plurality of connecting blocks 18 on the outer wall of the mounting seat 8. The connecting blocks 18 are buckled into the connecting grooves 17 to complete the assembly of the sealing member 5 and the cover 2. The width of the connecting groove 17 is matched with the connecting block 18, and the length of the connecting groove 17 is greater than that of the connecting block 18. When the movable channel 4 moves upward and downward, the connecting block 18 moves synchronously in the connecting groove 17.
[0034] The reset member 7 comprises first guide blocks 19 protruded on the two sides of the pressing block 3 and a second guide block 20 movably arranged in the cover 2.
