[0002] At present, the electric heating cup on the market mostly adopts stainless steel cup body or stainless steel heating disc to heat, and some products use glass for the cup body and are connected with the stainless steel heating disc at the bottom through the silicon rubber bonding mode. This kind of electric heating cup has the following main problems:

[0003] Food safety problem: since the heating component is mostly made of stainless steel material, long-term use may cause food safety concerns, especially in high-temperature environment, harmful substances are easily separated out, affecting the safety of drinking.

[0004] Poor portability: most traditional electric heating cups need to be powered through external power sockets, which makes it difficult for users to heat water or other liquids in outdoor environments without power supply, limiting the portability of the product.

[0005] Low heating efficiency: the traditional heating disc usually adopts a curved heating tube welded at the bottom of the stainless steel disc, and the heating efficiency is low, which leads to a long heating time and affects the user experience.

[0006] Heavy weight: the weight of the stainless steel heating disc and the cup body is large, which is not convenient to carry out, especially for users who need to be light and portable.

[0007] In addition, most electric heating cups adopt a single mode and single voltage heating mode, that is, either supporting household 220V mains heating or relying on lithium battery power supply. The single heating mode is difficult to meet the needs of home and outdoor use, limiting the multifunctionality of the product. INVENTION CONTENTS
