▎ 摘　　要

NOVELTY - The device (100) has a housing (2) that is set with cover housing that is set relative place on an inner container (4), power supply circuit and the internal housing. The intelligent fresh-keeping device includes a graphene composite film (7), and the power source circuit electrical property connection of a fan (8). The graphene composite film is set with fan for driving the air flow in an inner container, after the bacteria and the graphene composite film in air contact is killed in the inner liner inner side fan. USE - Intelligent fresh-keeping device. ADVANTAGE - The time of food fresh-keeping effect is prolonged. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the intelligent fresh-keeping device.
