The thermos cup is generally a water container made of ceramic or stainless steel with a vacuum layer, with a lid on the top and a tight seal. The vacuum insulation layer can delay the heat dissipation of liquids such as water inside to achieve the purpose of heat preservation. The thermos cup is developed from the thermos. The principle of insulation is the same as that of the thermos, but people make the bottle into a cup for convenience. There are three ways of heat transmission: radiation, convection and transmission. The silver cup inside the thermos can reflect the radiation of hot water, the vacuum of the cup and the cup body can block the heat transfer, and the bottle that is not easy to transfer heat can prevent heat convection. The current thermos flask also applies the principle of magnetized water, which is to add magnets to the bottom and cap of the bottle to make the water magnetized. It is said that magnetized water has magical effects.
The exterior is smooth and has no odor. After pouring boiling water, you can hold a thermos cup without heat in your hand. The inside and outside are made of stainless steel, refined with advanced vacuum technology, elegant in shape, seamless inner tank, good sealing performance, and good heat preservation performance. You can put ice cubes or hot drinks. At the same time, functional innovation and detailed design also make the new vacuum flask more connotative and practical
