Description

Heat preservation kettle

Technical Field

The utility model relates to an article for daily use, concretely relates to thermo jug.

Background

There are three ways thermal power can be transmitted: radiation, convection, and transfer. The silvery inner container of the thermos flask can reflect the radiation of hot water, the vacuum of the inner container and the flask body can block the heat transfer, and the flask body which is not easy to transfer heat can block the heat convection.

The traditional thermos bottle is a container which is made of ceramic or stainless steel and a vacuum layer and is used for containing water, the top of the container is tightly sealed by a cover, and the vacuum heat insulation layer can delay the heat dissipation of the water and other liquid in the container so as to achieve the purpose of heat preservation.

Many parents make milk powder for children, and the temperature of water is considered, because the temperature directly influences the nutritional value of the milk powder. If the temperature is too high, firstly, the milk powder is agglomerated and cannot be fully dissolved; secondly, whey protein in the milk powder can generate clot, the nutritional value of the milk powder is destroyed, and the digestion and absorption of children are influenced; if the temperature is too low, the milk powder is not easy to be soaked, and the dissolution of the milk powder and the digestion and absorption of the baby are directly influenced. When the child is carried with the child to go out and play, the temperature of the water brought out is too high or too low, which is not suitable for the child to eat, and therefore, the water also becomes an obstacle for limiting the travel of parents.
