Electric food warmer capable of achieving three-dimensional heating and never falling off from bottom

The invention discloses an electric food warmer with a three-dimensional heating function and without bottom falling, and relates to the technical field of electric food warmers. The pot body is arranged at the top of the bakelite base; the three positioning mechanisms are arranged in the bakelite base and used for limiting the pot body; wherein the pot body comprises an aluminum A layer, a heating pipe, an aluminum B layer, an aluminum C layer and a stainless steel layer, the heating pipe is arranged between the aluminum A layer and the aluminum B layer, the aluminum C layer is arranged on the aluminum B layer, the stainless steel layer is arranged on the aluminum C layer, and the aluminum heating pipe and aluminum outside the pot are welded together through the aluminum and aluminum welding technology to form a whole and cannot be separated. The quick heat conduction performance of aluminum is utilized, after the electric heating pipe is electrified, a complete heating body is formed outside the whole pot,
