Vacuum cup additionally provided with embedded phase change heat storage layer

The utility model relates to a vacuum cup additionally provided with an embedded phase change heat storage layer. The vacuum cup comprises a cup cover, a cup body and the embedded phase change heat storage layer. The cup body is provided with a double-layer shell formed by an outer cup body wall and an inner cup body wall. The embedded phase change heat storage layer is a cylinder which is made of stainless steel and is through, wherein the cylinder is provided with a closed interlayer side wall formed by double layers of the cylinder walls. The closed interlayer side wall of the cylinder is a shell of the embedded phase change heat storage layer. The shell of the embedded phase change heat storage layer is filled with change heat storage materials, so that an embedded phase change heat storage layer entity is formed. The embedded phase change heat storage layer is embedded in the double-layer shell of the cup body and tightly attached to the inner wall of the cup body for fixation. The outer cup body wall an
