Description

Technical Field

[0001] This utility model relates to the field of water cup technology, and in particular to a double-cup vacuum insulated cup. Background Technology

[0002] A vacuum cup, also called a vacuum insulated cup, is a water container made of stainless steel with a vacuum layer. It has a lid on top that is tightly sealed. The vacuum insulation layer can slow down the heat dissipation of the water or other liquids inside, thus achieving the purpose of heat preservation.

[0003] Vacuum cups have good heat retention, but most vacuum cups on the market have this problem: if the water inside the cup is very hot, the user cannot drink it directly and needs to cool it down first. The solution is either to open the lid in advance and let the water cool down, or to pour the water out of the cup to cool it down. Both of these methods take a certain amount of time and cannot meet the user's needs.

[0004] Some cup structures have also appeared on the market that can cool the hot water in a thermos through their own structure. The principle is to add a lid to use as a cup, and the outer shell of the lid is made into a double layer. The middle layer is sealed with a liquid with a high specific heat capacity. The liquid absorbs heat from the hot water poured into the lid to cool it down. Although this structure can cool down quickly, it also has new technical problems: this structure relies on the absorption of heat due to temperature difference to achieve cooling. However, the heat absorption capacity due to temperature difference is limited. The first cup of water may be cooled down quickly, but it will not be effective continuously. Utility Model Content
