Many people lose some small things when they move, or throw away some things when they move. At this time, people will re-buy them when they use them. Thermos cups and thermos cups are the things that are easy to lose. , so everyone will re-consider which cup is better when re-selection, let’s follow the editor to see the difference between a thermos cup and an insulated cup.
1. Different structure
The vacuum flask is generally a water container made of ceramic or stainless steel plus a vacuum layer. The top has a cover and is tightly sealed. The vacuum insulation layer can delay the heat dissipation of the water and other liquids contained in it to achieve the purpose of heat preservation. The thermal insulation effect of the thermos cup is mainly that the cup is not hot, and it can ensure that the water in the cup is isolated from the outside air, so as to achieve the function of insulating water.
The insulated cup includes the inner cup and the bottom of the cup. Unlike thermos cups, thermos cups don’t have to have a lid on top. The heat insulation of the heat-insulating cup mainly means that the outer cup is provided with an outer cup, and an air layer for heat insulation is formed between the outer cup and the inner cup, just to prevent the water in the cup from being hot. Only vacuum mugs and double-layer glasses have the dual function of keeping warm and insulating.
In addition to the outer cup outside the inner cup, some heat-insulating cups are also provided with a number of reinforcing heat-insulating ribs on the outside of the cup wall, and cup-rim reinforcing ribs are respectively provided under the cup rim and on the outside of the cup wall of the cup mouth. and connecting ribs, an upper boss, a middle boss and a lower boss are respectively arranged on the inner side of the cup wall from top to bottom. Compared with the existing cup, the utility model has the characteristics of simple structure, beautiful use, heat insulation and not hot to the hand. Moreover, the heat-insulating reinforcing rib it uses not only increases the strength of the cup but also saves the trouble of using the cup holder.
2. The principle of heat preservation is different
A thermos cup is a thermos-like structure, a cylindrical container made according to the Dewar principle in order to keep liquids or solids (ice) hot or cold for several hours. The thermal insulation cup has a structure similar to a vacuum liner, which seals the two layers of the cup wall and draws it into an approximate vacuum, which reduces the heat conduction and plays a role in heat preservation.
3. Different uses
Insulation cups are good for drinking boiled water, and should not be used to brew acidic substances such as tea, coffee or milk; insulation cups are different, except for stainless steel vacuum insulation cups Plastic cups can be used to make tea or hold other drinks, and heat-insulating cups are mostly used in the production of coffee cups.
