There are three ways to spread heat: radiation, convection and transmission. The silver liner in the thermos cup can reflect the radiation of hot water, and the vacuum between the liner and the cup can block the heat transfer, while the bottle which is not easy to transfer heat can prevent the heat convection. The hot water bottle also applies the principle of magnetized water, that is, magnets are added to the bottom and cap of the bottle to magnetize water.
Both inside and outside are made of stainless steel, refined by advanced vacuumizing technology, with elegant appearance, seamless inner container, good sealing and good thermal insulation performance. You can put ice cubes or hot drinks. At the same time, functional innovation and detailed design also make the new thermos cup more connotative and practical.
Pay attention to shopping
1, select the manufacturer with normal quality.
The health pot produced by the manufacturer has beautiful appearance, and the upper cover and heating plate are made of imported high-quality stainless steel, which will never rust, be evenly heated and not be easily scalded. At the same time, the temperature control device is accurate and stable, ensuring that nutrients are not lost. Inferior health pots are obviously poor in workmanship and easy to rust.
2, the material should be safe
The plastic smell of inferior health pot after boiling water is very heavy, because the apron used to seal the heating plate is made of non-food grade ordinary silica gel. When the upper part of the apron comes into contact with water and is heated and decomposed by the heating plate, it will continuously release odor and harmful substances, which is harmful to human health. Regular health pots are non-toxic and tasteless, and most of them use imported food-grade silicone rings.
