Description

a heating insulator

technical field

The utility model relates to daily necessities, in particular to a heating and warming device mainly used for liquid heating and heat preservation and disinfection of dining utensils.

Background technique

In the transportation of daily life, people often have requirements for heating and heat preservation of liquids such as water, tea, and coffee. For example: for water, people usually ask to boil raw water, but the real drinking temperature is neither the boiling temperature of boiling water -100 degrees Celsius, nor the temperature at which boiling water is completely cooled down---that is, the temperature close to room temperature, but It is a relatively specific temperature between the two. For example: the most suitable temperature for human drinking is usually 37-42 degrees Celsius. In addition, people also need to sterilize the catering utensils, especially the catering utensils for infants and young children, in water at high temperature. If you buy a sterilizer separately, you need to spend a lot of money. It is easy to make the catering utensils only rely on the ultra-high temperature bottom of the heating container, especially the plastic catering utensils, which are often damaged because of this, and there is no time to set it, and sometimes it is forgotten, resulting in dry burning, damage to the catering utensils, and even serious damage. fire.
