[0005] (3) Regional resources are not utilized: China has 37 known high-quality (Sr2+>0.2mg / L) natural water sources (data source: 2022 Ministry of Natural Resources report), but existing patents (such as CN108658320A) still rely on later mineralization additions.

[0006] (4) Limitations of sterilization technology: Traditional UV sterilization has an inactivation rate of only 90% for Cryptosporidium (Reference 2: Water Res., 2019), and requires multi-stage treatment, which increases costs.

[0007] 2. Comparative Patent Analysis

[0008] CN108658320A: Multi-stage filtration + dynamic pH adjustment, but the mineralization step relies on static soaking of medical stone, which takes 8 to 12 hours, and the Sr2+ content is uncontrollable.

[0009] US20170251834A1: Nanobubbles increase oxygenation but do not solve the problem of mineral retention.

[0010] EP3260436B1: The bottle body material is degradable, but the risk of secondary contamination at the bottle mouth is not optimized. Summary of the Invention
