Detailed explanation of the internal structure of the thermos bottle

1. Thermal Insulation Principle of Thermos BottleThe thermal insulation principle of the thermos bottle is vacuum insulation. The thermos flask has two layers of copper-plated or chromium-plated glass shells inside and outside, with a vacuum layer in the middle. The existence of vacuum prevents heat from being transferred through conduction, convection, radiation, etc., thus achieving the thermal insulation effect. At the same time, the lid of the thermos bottle is also insulated, which can effectively slow down the loss of heat.

2. Internal structure of thermos bottleThe internal structure of the thermos bottle mainly consists of the following parts:

1. Outer shell: usually made of stainless steel or plastic material.

2. Hollow layer: The vacuum layer in the middle plays a thermal insulation role.

3. Inner shell: The inner shell is generally made of glass or stainless steel. The inner wall is often coated with a special oxidation treatment to prevent drinks from damaging the material. This is why it is not recommended to use acidic drinks such as juice in thermos bottles. reason.

4. Lid structure: The lid is generally made of plastic and silicone. Some thermos bottle lids are also made of stainless steel. There is usually a small triangular opening on the lid for pouring water, and there is a sealing ring on the lid for pouring water. seal.

3. Maintenance of thermos bottles

1. Empty the hot water promptly after drinking it to avoid corrosion caused by long-term storage.

1. After using the thermos flask, rinse it with clean water, and pour out all the accumulated water inside the thermos flask, the lid, and the mouth of the bottle to avoid accumulation of dirt caused by residual moisture.

2. Do not put the thermos bottle directly into the refrigerator or high-temperature environment to prevent the bottle wall from shrinking or deforming due to heat.

3. Only warm water can be put into the thermos bottle. It is not suitable to put drinks that are too hot or too cold to avoid damaging the vacuum layer and internal shell inside the thermos bottle.

In short, the internal structure of the thermos bottle is very important. By understanding the internal structure of the thermos bottle, we can better understand the insulation principle of the thermos bottle, and become more comfortable when using and maintaining the thermos bottle.
