The internal structure of the stainless steel thermos cup,the stainless steel thermos cup is a common thermal insulation container,it can effectively maintain the temperature of the drink,allowing us to enjoy hot drinks outdoors or in the office at any time.So,what is the internal structure of the stainless steel thermos cup?ervanflask will introduce you in detail.The internal structure of the stainless steel thermos cup mainly includes the following parts:vacuum layer,liner,sealing cover and straw.

　　The first is the vacuum layer.The interior of the stainless steel thermos cup usually has an air-tight vacuum layer.This vacuum layer is formed by the gap between the two layers of stainless steel cups.The role of the 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.

　　Followed by the liner.The liner is the inner container of the stainless steel thermos cup,which is used to hold drinks.The liner is usually made of food-grade stainless steel,which has good corrosion resistance and thermal insulation properties.The stainless steel material will not produce odor or chemical reaction to the drink,ensuring the purity and safety of the drink.The interior design is usually smooth for easy cleaning and maintenance.

　　The third is the sealing cover.The sealing lid is the top cover of the stainless steel thermos cup,which is used to seal the cup body and prevent the temperature loss and leakage of the drink.The sealing cap is usually made of food-grade silicone material,which has good sealing performance and high temperature resistance.Some airtight lids are also equipped with a switch button or a twist lid,which is convenient for users to open and close the lid,and drink or pour water.

　　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 internal structure design of the stainless steel thermos cup is reasonable.Through the cooperation of the vacuum layer,the inner tank,the sealing cover and the straw,it can effectively maintain the temperature of the drink,and it is convenient for users to use and clean.The design of the internal structure of the stainless steel vacuum flask allows us to enjoy warm or cool drinks anytime and anywhere,bringing convenience and comfort to our lives.
