The slider 300 and the liquid sealing piece 200 are mounted on the upper surface and the lower surface of the lid body 100 respectively, the slider 300 can control the liquid sealing piece 200 to move, and the liquid sealing piece 200 can move horizontally on the lower surface of the lid body 100 to seal or open the liquid outlet 110; because the slider 300 needs to be connected to the liquid sealing piece 200, the connecting pillar 310 is arranged to connect the slider 300 and the liquid sealing piece 200; the connecting pillar 310 is configured as a columnar structure, which is arranged on the slider 300, protrudes downwards and is inserted into the liquid sealing piece 200; or, the connecting pillar 310 is a columnar structure, which is arranged on the liquid sealing piece 200, protrudes upwards and is connected to the slider 300; that is, the connecting pillar 310 is arranged one of the slider 300 and the liquid sealing piece 200 and is connected to the other one of the slider 300 and the liquid sealing piece 200; the via hole 120 is configured to allow the connecting pillar 310 to penetrate through and move, the connecting pillar 310 penetrates through the lid body 100 through the via-hole 120, and when the slider 300 slides, the connecting pillar 310 moves synchronously to drive the liquid sealing piece 200 to move.

The liquid sealing piece 200 seals the via hole 120 when located at any position (including the closed position and the open position), such that liquid in a cup cannot flow out via the via-hole 120. When the liquid sealing piece 200 is located at the open position, the liquid outlet 110 is opened, and liquid flows out through the liquid outlet 110. When the liquid sealing piece 200 is located at the closed position, the liquid outlet 110 is sealed, and liquid cannot flow out through the liquid outlet 110. The liquid sealing piece 200 slides horizontally on the lid body 100, which means that when located at the closed position, the liquid sealing piece 200 will not be opened unless it is laterally pushed, and covers the bottom of the liquid outlet 110, and the liquid sealing piece 200 will not be ejected open by hot steam when hot liquid is stored in the cup, thus fulfilling a good sealing and heat insulation effect; meanwhile, the liquid sealing piece 200 will not be closed when users drink liquid like a flip lid, making the cup lid convenient to use.

The slider 300 can be shifted to control the liquid sealing piece 200 to slide to seal or open the liquid outlet 110, such that operation is extremely convenient, the overall structure is simple and reliable, and the sealing effect is good.

As shown in FIG. 1 and FIGS. 4-6, based on the above embodiment, the liquid sealing piece 200 is provided with a sealing ring 210 in contact with the lower surface of the lid body 100, and the liquid sealing piece 200 has a sealing region 220 encircled by the sealing ring 210. When the liquid sealing piece 200 is located at the closed position, the sealing region 220 covers the liquid outlet 110. When the liquid sealing piece 200 is located at any position within the sliding range, the sealing region 220 covers the via-hole 120.
