Similar in shape to a cup, it is divided into a cup body and a cup cover.

principle

After boiling water is poured into the smoldering cup, food is put into the cup when it is used, and the temperature in the cup is kept for a long time by its heat preservation function.

Cover: prevent heat from spreading.

Vacuum interlayer: prevent conduction and convection heat transfer.

Metal shell: prevent radiation heat from spreading.
