The purpose and structure of the thermos?

Uses: The shell of the thermos pot is made of bamboo, plastic, iron sheet, aluminum, stainless steel, and other materials. There is a rubber gasket at the mouth of the thermos bottle and a bowl-shaped rubber seat at the bottom of the bottle. The shell collides. The worst part of the heat preservation and cold preservation function of the thermos is around the neck of the bottle, where most of the heat circulates using conduction. Therefore, the bottleneck is always shortened as much as possible when manufacturing. The larger the capacity and the smaller the bottle mouth, the better the heat preservation effect. Around 60°C. Vacuum bottles are closely related to people's work and life. It is used to store chemicals in laboratories, and people use it to store food and drinks at picnics and football games. In recent years, many new patterns have been added to the water outlet of thermos bottles, and pressure thermos bottles, contact thermos bottles, etc. have been produced, but the principle of heat preservation remains unchanged.

Structure: an energy-saving thermal insulation pot belongs to the kitchen equipment, especially a pot for boiling water. The energy-saving heat preservation pot includes a pot wall and a spout, and its structure is as follows: the outer surface of the pot wall is wrapped with an insulating layer, and the outer side of the insulating layer is provided with a protective layer. Because the insulation layer is wrapped outside the kettle wall, it can reduce the heat dissipation of the kettle wall and reduce energy loss to achieve the effect of energy saving and heat preservation. Because there is another protective layer outside the insulation layer, it can prevent the soft insulation layer from being damaged, and at the same time, it is easy to clean the pot. Outer surface for easy access.
