Why does the stainless steel liner of Mi Smart Kettle Pro leak partially?

The stainless steel liner is partially leaking due to the fact that the metal ring may come into contact with water when pouring, and in order to ensure that all areas that may come into contact with hot water for a long period of time are made of food-grade stainless steel, with no possibility of plastic coming into contact with the water. The traditional wrapping, plastic wrapped stainless steel part will hide the dirt.
