Schematic diagram of stainless steel thermos cup,stainless steel thermos cup is a common thermal insulation container,it can effectively maintain the temperature of the drink,so that we can enjoy hot drinks outdoors or in the office at any time.So,what is the principle of the stainless steel thermos cup?Ervan Flask Water Flask Manufacturer will introduce you in detail.

　　First of all,the internal structure of the stainless steel thermos cup mainly includes the following parts:vacuum layer,inner tank,sealing cover and straw.

　　Secondly,the vacuum layer is a key part of the stainless steel thermos cup.It is formed by the gap between the two layers of stainless steel cup body.The role of this vacuum layer is to prevent heat conduction,thereby reducing heat loss.By maintaining the temperature of the drink,the vacuum layer ensures that the drink stays hot or cold for a longer period of time.

　　Next is the liner.The liner is the container inside the stainless steel thermos cup,which is used to hold drinks.The liner is usually made of food-grade stainless steel,which has the characteristics of high temperature resistance,corrosion resistance and no peculiar smell.The stainless steel material can effectively maintain the temperature of the drink without affecting the taste of the drink.

　　In addition,the airtight lid is also an important part of the stainless steel thermos cup.The sealing cap is usually made of food-grade silicone or plastic material,which has good sealing performance.It can effectively prevent heat loss and external pollution,and ensure the temperature and quality of drinks.Some sealing lids are also equipped with a switch or button,which is convenient for the user to open or close the lid.

　　And finally the straw.Some stainless steel thermos cups are also equipped with straws,which are convenient for users to drink directly.Straws are usually made of food-grade silicone or plastic material,which is soft and durable.The design of the straw allows the drink to be sucked directly from the bottom of the cup,which is convenient for the user to drink.

　　In general,the principle of the stainless steel thermos cup is to achieve the effect of heat preservation through the cooperation of the double-layer structure,vacuum layer,inner tank,sealing cover and straw.The stainless steel thermos cup can effectively isolate heat conduction and convection,reduce heat loss,and maintain the temperature of the drink.At the same time,the design of the sealing cover and the straw is also convenient for users to use and clean.The schematic diagram of the stainless steel thermos cup shows the design of its internal structure,so that we can enjoy warm or cool drinks anytime and anywhere,bringing convenience and comfort to our lives.
