▎ 摘　　要

NOVELTY - Vacuum insulation cup (1) comprises a cup cover (2) and a cup body (4). The cup cover is provided with an annular water sealing ring (3). The cylinder body is fixedly connected with the cup base. A vacuum insulating layer (5) is used for preventing the heat inside in the cylinder body from being lost to the environment and an inner liner layer is an integrally formed stretching structure. A heat conductive layer is provided between the filling layer and the inner liner layer. The heat conducting layer comprises multiple heat conducting wires and/or a heat conducting wire mesh is formed by the heat conducting wires and/or a heat conducting sheet. The filling layer is filled with phase change energy storage composite material with high enthalpy value to realize function of heat absorption and temperature reduction and heat release heat preservation and the phase-change energy-storage composite material is multi-layer net-shaped structure cross-linked with each other. USE - Used as vacuum insulation cup. ADVANTAGE - The vacuum insulation cup ensure that both high-temperature water and low-temperature water can be adjusted to suitable water temperature by utilizing inherent properties of high enthalpy phase change energy storage composites and satisfies the needs of consumers to quickly drink warm water. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for use method of vacuum insulation cup comprising adding water with a temperature greater than 60degrees Celsius into a cylinder, changing the phase change energy storage composite material in a filling layer from solid to liquid, absorbing the heat of the high temperature water, reducing the water temperature, maintaining the temperature at 40-60degrees Celsius, adding the water with the temperature lower than 40degrees Celsius into the cylinder, changing the phase change energy storage composite material in a filling layer from liquid to solid, discharging heat, reducing the water temperature and maintaining the temperature at 40-60degrees Celsius. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the vacuum insulation cup.
