Description

Technical Field

[0001] This utility model belongs to the technical field of electric heating tables, specifically relating to an electric heating table whose tabletop and middle layer can be raised and lowered synchronously. Background Technology

[0002] An electric heated table, also known as an electric heating table, is a new type of heating appliance that integrates a table and a heater. Based on the traditional table, it incorporates modern technology and aesthetics, utilizing far-infrared radiation and convection heating. Currently, electric heated tables are mainly divided into several types: electric ceramic stove heated tables, electric heated coffee tables, electric heated dining tables, electric heated desks, and electric heated mahjong tables. Compared with traditional heating tools, electric heated tables have the following advantages: rapid heating, relatively even temperature maintenance, convenient temperature adjustment (speed adjustable), independent heating with less influence from power supply voltage, long lifespan, and a design that complements home décor, with a beautiful and elegant appearance.

[0003] However, currently, electric heating tables do not have a middle layer structure, or the middle layer structure cannot be adjusted in height and is a fixed middle layer structure. When users need to warm their feet, they can only place their feet on the base. The middle layer structure cannot be adjusted according to different usage heights or the comfort of the human body's sitting posture, which leads to a poor user experience and reduces the product's attractiveness and market competitiveness.

[0004] Therefore, further improvements are needed. Utility Model Content
