A kind of heat storage insulation water cup

Abstract

The invention provides a heat-storage and heat-insulating water cup, which includes a cup body and a cup lid screwed to the cup body. The cup body includes an inner wall and an outer wall, and there is an interlayer between the inner wall and the outer wall. space; the inner wall is made of stainless steel, and the outer wall is made of organic glass with a thermal conductivity less than 0.2W / (m.K); the interlayer space is provided with phase change heat storage material. The insulated water cup provided by the invention has a simple structure and is easy to use. It adopts a sheath structure of stainless steel and organic glass. A phase change heat storage material is provided in the interlayer space of the two, so that the water in the water cup can be adjusted at a constant temperature. The heat preservation time of water is greatly extended, and the water temperature will not be too high when heated. Ultimately, the purpose of long-term temperature control and heat preservation is achieved, allowing people to drink warm water at any time.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to a thermal storage heat preservation water cup based on a phase change thermal storage material. Background technique [0002] With the advancement of technology, the pace of life is gradually accelerating, and time is becoming more and more precious. When people use traditional thermos cups filled with boiling water, the water temperature is too high when they want to drink water in summer, and they will find that the water temperature in the thermos cup is too long when they drink in winter, and the water temperature is always not as ideal as they want temperature. It takes a long time to wait for the boiling water to gradually cool down using a traditional vacuum flask. If the water in the traditional thermos cup is too cold, it is okay in summer, but it can only be reheated in winter, which wastes time and cannot guarantee warm water. At this time, people are in urgent need...

AI Technical Summary

Problems solved by technology

Looking at the thermal insulation water cups on the market today, thermal insulation materials and heat insulation vacuum layers are generally used. Although this kind of water cup has the effect of heat preservation on hot water, because the thermal conductivity of the material is fixed, and the heat is always transferred from high energy to low energy, The heat loss is one-way, and the heat loss continues to occur, making it impossible to keep the temperature of the water in the cup stable at 45-55°C for a long time
