Rotating the rotating cover 3 drives the water sealing member 6 to rotate through the clamping portion 11.

[0031] The utility model aims to provide an inner plug cup lid which is simple in structure, can realize simple and quick water discharge, is convenient and quick to operate, and is durable. The utility model comprises an outer cover 1 and a water sealing member 6 which is threadedly connected to the outer cover 1. The water sealing member 6 can be rotated to make the water sealing member 6 move up and down along with the thread. A water passage 8 is provided on the outer cover 1. A water outlet 4 is provided at the lower end of the water passage 8. A water sealing portion 5 for blocking the water outlet 4 is provided on the water sealing member 6. The water sealing portion 5 is located at the lower end of the water outlet 4. The water sealing portion 5 can be driven to move vertically up and down along the water sealing member 6 by rotating the water sealing member 6, thereby opening or closing the water. The water outlet 4 is closed, a rotating cover 3 is provided on the outer cover 1, a clamping portion 11 is provided on the rotating cover 3, a clamping groove 12 is provided on the clamping portion 11, a receiving groove 9 is provided on the water sealing member 6, a baffle 10 is provided in the middle of the receiving groove 9, the clamping portion 11 is provided in the receiving groove 9, the clamping groove 12 is clamped with the baffle 10, and both sides of the clamping portion 11 abut against the baffle 10. The rotating rotating cover 3 drives the water sealing member 6 to rotate through the clamping portion 11. The utility model drives the water sealing member 6 to rotate relative to the outer cover 1 by rotating the rotating cover 3. Because the outer cover 1 and the water sealing member 6 are threaded, the rotating cover 3 rotates and drives the water sealing member 6 to rotate relative to the outer cover 1. The water sealing member 6 is connected and vertically positioned in the outer cover 1. When the water sealing member 6 and the outer cover 1 are driven to rotate relative to each other by rotating the rotating cover 3, the connecting member will move axially in the connecting tube and drive the water sealing plate to move. The press-type inner plug cup cover currently on the market has a reduced sensitivity of the button after being used for a period of time. The elastic member is prone to lose its elasticity or fail to reset in place during long-term pressing and resetting. In severe cases, the cup cover will not be able to be effectively sealed or opened directly, shortening the service life of the cup cover. The utility model is connected to the outer cover 1 by a thread, and the water sealing member 6 can be driven to move the water sealing portion 5 by rotating the water sealing member 6. When opening the lid, the water sealing member 6 is rotated to move downward, and the water sealing part 5 moves downward accordingly, so that the water outlet 4 is opened. When the cup body is tilted, water can flow into the water passage 8 from the water outlet 4 and flow out from the water passage 8. When closing the lid, the water sealing member 6 is rotated to move upward, and the water sealing part 5 moves upward accordingly, so that the water sealing part 5 blocks the water outlet 4, and the lid can be closed, which is convenient for opening and closing the lid and is more conducive to the use of customers.
