[0002] The inner plug cover is a kind of cup cover, which is usually installed in the cup mouth of the cup body. When in use, the drinking port on the inner plug cover is connected to the inside of the cup body by flipping the cover or controlling the button. In order to keep the inner plug cover clean and hygienic, an outer cover is often installed on the outside of the inner plug cover. During use, the outer cover shell is used as a water cup.

[0003] For example, the cup lid structure disclosed in Chinese utility model patent application CN202120038895.3 includes a main cover body, a cover opening assembly and a closing plug. The cover opening assembly includes a pressure cover, a limit sleeve and a movable block. The limit sleeve is fixedly connected to the main cover body, the movable block is arranged in the limit sleeve and cooperates with the limit sleeve for rotation. The pressure cover is slidably connected to the main cover body up and down to drive the movable block to move. A reset spring is provided between the movable block and the inner wall of the main cover body. The top of the closing plug passes through the movable block and is threadedly connected to the pressure cover, and the bottom of the closing plug is sealed with the lower opening of the main cover body. The advantage is that the limit sleeve and the movable block are fixed to the main cover body at the same time through the threaded connection between the closing plug and the pressure cover. All internal parts can be removed by unscrewing the closing plug. The overall structure is simple, disassembly is more convenient, and cleaning is convenient.

[0004] The above-mentioned cup cover cannot be connected to the outer cover, and the outer cover can only be installed on the cup cover by a threaded structure or a clamping structure, which is not convenient for quick installation and disassembly of the outer cover. During use, the inner sleeve and the pressure cover will move relative to each other, and the drink can easily pass through the gap between the inner sleeve and the pressure cover, resulting in drink residue between the main cover body and the pressure cover, affecting the cleanliness and hygiene of the cup cover.
