The invention provides a heat storage and insulation water cup. The heat storage and insulation water cup comprises a cup body and a cup cover, wherein the cup cover is screwed and covered on the cup body; the cup body comprises an inner wall and an outer wall, and an interlayer space is formed between the inner wall and the outer wall; the inner wall is made of a stainless steel material, and the outer wall is made of organic glass with heat conduction coefficient less than 0.2W/(m.k); a phase-change heat storage material is arranged in the interlayer space. The heat storage and insulation water cup has the advantages that the structure is simple, and the convenience in use is realized; by adopting a jacket layer structure of stainless steel and organic glass, the phase-change heat storage material is arranged in the interlayer space, water in the water cup can be constant in temperature by adjusting, the heat insulation time of the water in the water cup is greatly prolonged, the overhigh water temperature is avoided in a heating process, and the purpose of controlling and insulating heat for a long time is realized; people can drink warm water at any time.
