Power supply device for warm-keeping and heating of container

Abstract

The battery is arranged in the bottom case, and the battery supplies power to the heating plate located on an upper end of the bottom case through a wire. By arranging the heating device and the bottom case and arranging the battery and the heating plate, heating and warm-keeping functions can be realized, so that heating and warm-keeping of the container that needs to be heated can be realized in any place without connection to a power supply, which brings great convenience.
