The Xiaomi Instant Water Heater S1 comes equipped with a 3L water tank, but having to remove it to fill it every day can be a bit inconvenient. While there's an accompanying water intake hose, it looks a bit unsightly when attached.

Therefore, based on the structure of the original water tank, I designed a decorative water tank that allows the water heater to use the intake hose while maintaining its overall integrity and aesthetics.
