Description

Heat preservation kettle

Technical Field

The utility model relates to the field of heat preservation appliances, in particular to a heat preservation kettle.

Background

Modern thermo jug was invented in 1892 by the physicist james dewajazz, uk. When he was working on a study of liquefying gases at low temperatures, he first designed a container that isolates the gas from the outside temperature, and then asked a glass technician berg to blow a double glass container into which the inner walls of the two layers were coated with mercury, and then to evacuate the air between the two layers to create a vacuum. The vacuum bottle, also called 'Du bottle', can keep the liquid in the vacuum bottle constant for a certain time no matter the temperature is cool or hot. Because the thermos bottle is mainly used for keeping hot water warm in families, the thermos bottle is also called as a thermos bottle. The construction of the thermos is not complicated. The middle part is a double-layer glass bottle liner, the two layers are vacuumized and silver or aluminum plated, the vacuum state can avoid heat convection, the glass is a poor heat conductor, and the silver plated glass can reflect heat energy radiated outwards in the container. Conversely, if the bottle stores cold liquid, the bottle prevents external heat from being radiated into the bottle. The stopper of a thermos bottle is usually made of cork or plastic, and the cork and the plastic are both materials which are not easy to conduct heat.

However, the rational design of the liner structure of the thermos bottle and the protection of the liner are important factors affecting the use performance of the thermos bottle. The existing thermos pots are various in types, but most of the thermos pots cannot completely exert the due heat preservation effect of the thermos pots on the protection of the glass liner and the structural design of the glass liner.

Therefore, how to provide a thermos flask which can overcome the above problems is a problem to be solved by those skilled in the art.
