My family's cooking pot

Do you have a stranger to this word? That's right, this is a newly developed thermos bottle. There is one in my house. Let's take a look!

It is wearing a large cylindrical coat with a "small scorpion" on the head for easy access. Inside the "big coat" is a beautiful silver fabric, very beautiful. Let's see what it looks like! Like its "big coat", it is also a cylindrical shape. Its body is made of stainless steel and is very beautiful silver gray.

Let's see what its "visceral" is! Unscrew the lid and you will be surprised to find that it actually "wears" three "hats." Looking inside, you will find a circle of protruding parts, which is used to seal the rubber ring of the lid. This type of sealing is usually better than other sealing methods. In addition, its body is not all stainless steel. In the outer casing of stainless steel, there is a copper-plated outer wall of the inner liner. This is to delay the heat radiation and achieve the effect of long-lasting insulation. At the end of the liner, there is some getter that will "wake up" it at high temperatures when vacuumed to capture residual gas to extend vacuum life. Finally, at the bottom of the pot, there is a circle of plastic bottom, which protects the vacuumed part and the structure of the complete cup.

You definitely want to ask, what is the purpose of this pot? Don't worry, listen to me slowly: this pot can keep warm and keep cold, more importantly: If you want to eat porridge tomorrow morning, you don't have to get up early in the morning to cook porridge, just pour boiling water and wash it at night. The next morning, the hot porridge is waiting for you. Such a thermos pot is best for those who need to get out early.

how? Do you have some understanding of this new type of insulation pot?
