The vacuum cup is also called a vacuum insulation cup. It is generally a water container made of stainless steel and a vacuum layer. There is a cover on the top and it is tightly sealed. Purpose. So what are the differences between vacuum cups and ordinary thermos cups? Let’s take a look with Sleide below!
Difference 1: Insulation performance
The characteristics of the vacuum insulation cup are cold and heat preservation, and the vacuum cup with a high vacuum rate can have a heat preservation effect of up to 10 hours.
However, ordinary thermos cups have low thermal insulation performance, and their heat dissipation performance is stronger than that of vacuum cups. The thermal insulation performance can usually reach about two to three hours.
Difference 2: Material
The vacuum insulation cup is just a cup body made of stainless steel and a vacuum layer. The vacuum insulation layer can delay the heat dissipation of water and other liquids inside to achieve the purpose of heat preservation.
Ordinary thermos cups have a variety of materials, most of which are stainless steel, ceramics, plastics, glass, and purple sand。
Difference 3: How it works
The vacuum insulation cup is generally a water container made of stainless steel and a vacuum layer. It is made of double-layer stainless steel inside and outside. The air is pumped out to achieve the effect of vacuum insulation.
The thermos cup is developed from the thermos bottle. The principle of heat preservation is the same as that of the thermos bottle, but people make the bottle into a cup for convenience. The silver liner in the thermos cup can reflect the radiation of hot water, the vacuum of the liner and the cup body can block the transfer of heat, and the bottle that is not easy to transfer heat can prevent heat convection.
Difference 4: Price
The ordinary thermos cups sold in the general market only have the effect of heat insulation. After injecting hot water, the heat preservation usually takes about two to three hours. The price of this ordinary thermos cup is quite different from that of the vacuum thermos cup. Far. Everyone should keep their eyes open when buying, carefully identify the merchants of the thermos cups, and don’t buy them on the street casually. The safety and warmth performance of this kind of relatively cheap thermos cups cannot be effectively guaranteed.
Difference 5: Touch feel
Pour boiling water into the cup, and you can feel the difference by touching the outer body of the cup after a minute: the hot one is not a vacuum thermos cup, but just an ordinary simple thermos cup; the non-hot one is a vacuum thermos cup. Vacuum insulation cups can generally keep warm for more than 6 hours, and those with high vacuum rate can reach about 10 hours.
How about it, do you understand the difference between the vacuum thermos cup and the ordinary thermos cup?
