Special reminder: when using the cleaning cup for the first time, 

be sure to pay attention to a row of 4 holes "anion release hole" above the cup body, and do not enter the water to prevent the digital circuit control from malfunctioning. Into the water, try to throw water out with moderate force (pay attention to safety, do not crush the cup), and put it in a cool and ventilated place for a week or so to air dry "self-healing". All plug-in type, rechargeable hydrogen-rich kettle, cup The same problem exists!
