Furthermore, the first sealing ring 24 and the second sealing ring 25 can seal the disassembled inner liner 15 to prevent water leakage.
[0034] Working principle: After prolonged use, if the inner liner of the thermos cup accumulates a large amount of stubborn stains, the user can rotate and remove the inner liner 15. This causes the mounting block 16 to rotate on the buffer pad 14, allowing the mounting block 16 to detach from the buffer pad 14. This allows the user to remove the inner liner 15 from the fixed inner liner 11, facilitating cleaning and replacement. Furthermore, users can install inner liners of different materials or with auxiliary structures inside the thermos cup, improving its practicality.
