Problems solved by technology

[0003] However, since the filter is built into the overflow protection cup, ordinary users cannot disassemble and clean the overflow protection cup during use.
Therefore, the current overflow protection cups are all disposable as a whole. After use, the entire cup must be replaced in a complete set, and the cost of use is high; and the dirty liquid is easy to overflow, resulting in cross-contamination and difficult environmental protection.
