Vacuum cup or vacuum flask, which one should I choose?

In autumn, everyone loves to drink water with stainless steel water bottle or stainless steel drinking cups. Different styles of insulated tumbler have different quality, and the duration of heat preservation is different. How should I ensure that the liquid stays at room temperature? What is the function of the vacuum cup and the vacuum flask? How should I choose? 

 

The difference between ordinary vacuum flask and vacuum flask

 

Different materials

Ordinary vacuum flasks have a variety of materials, including ceramic, stainless steel, plastic, purple sand and glass.

The vacuum insulation cup is only a cup body composed of stainless steel and a vacuum layer. The vacuum insulation layer can delay the heat dissipation of liquids such as water inside to achieve the purpose of heat preservation.

 

Different price

The ordinary thermos mugs sold on the market only have the effect of heat insulation. After the hot water is filled, the heat preservation is usually about two to three hours. The price of this ordinary thermos mug is comparable to the price of a vacuum thermos mug. There is a big difference. Everyone should carefully screen the merchants of the thermos when buying. Don't choose cheap stainless steel tumblers randomly. The safety and warmth performance of this kind of cheaper thermos cannot be guaranteed.

 

Different insulation performance

The vacuum insulation cup has the characteristics of keeping cold and heat, and the insulation effect of the vacuum cup with high vacuum rate can reach 10 hours. The heat preservation performance of ordinary vacuum cups is lower, heat dissipation is stronger than vacuum cups, and the heat preservation performance is usually only two to three hours.

 

Different touch

Go to the cup in one minute and fill it with boiling water, and then touch the outer body of the cup to make a difference. The hot one is an ordinary thermos vacuum insulated bottle. If it is not hot, it is a thermos vacuum insulated bottle. The vacuum insulated flask can generally keep heat for more than 6 hours. The high rate can reach about 10 hours.

 

Working principle is different

The stainless steel tumbler is developed from a thermos. The principle of insulation is the same as that of a thermos, but people make the bottle into a cup for convenience. The silver cup inside the thermos can reflect the radiation of hot water, the vacuum of the cup and the cup body can block the transfer of heat, and the bottle that is not easy to transfer heat can prevent heat convection.

 

Vacuum insulation cups are generally made of stainless steel plus a vacuum layer to hold water. It is made of double-layer stainless steel inside and outside. The inner and outer shell are combined by welding technology, and the inner and outer shell are connected by vacuum technology In the mezzanine.
