Introduction Of Vacuum Mug

It is generally a water container made of stainless steel and a vacuum layer. The top has a cover and is tightly sealed. The vacuum insulation layer can delay the heat dissipation of the water and other liquids contained in it to achieve the purpose of heat preservation. The thermos cup is developed from the thermos bottle. The principle of heat preservation is the same as that of the thermos bottle, but people make the bottle into a cup for convenience. There are three ways of heat transmission: radiation, convection and transfer. The silver cup in the thermos cup can reflect the radiation of hot water, the vacuum of the cup and the cup body can block the transfer of heat, and the bottle that is not easy to transfer heat can prevent heat convection.
