Description

Heat insulation cup

Technical Field

The invention belongs to the technical field of cups, and particularly relates to a vacuum cup.

Background

The vacuum cup is a container which is made of ceramic or stainless steel and a vacuum layer and is used for containing water, the top of the vacuum cup is provided with a cover which is tightly sealed, the vacuum heat insulation layer can delay heat dissipation of liquid such as water and the like in the vacuum cup so as to achieve the purpose of heat preservation, and the vacuum cup is a cup which can keep the temperature of drinking water in the cup slowly changing. The thermos cup comprises a cup body and a cup cover. The vacuum cup comprises a double-layer vacuum cup, a foam vacuum cup and the like. The cup body of the double-layer vacuum cup comprises an inner layer, a shell and a gap layer gap between the inner layer and the shell. The inner layer of the double-layer vacuum cup is the place for containing drinking water. The gap layer of the double-layer vacuum cup is filled with air, the air density is low, and heat transfer is not easy, so that the air is selected as the heat insulation material; although the heat-preserving cup can delay the heat dissipation of hot water, when a user urgently needs to drink water, inconvenience is brought to the user due to too slow heat dissipation; especially, when children use the thermos cup, the children are hurried when drinking water because the children have poor patience, and if the hot water temperature in the thermos cup is too high, the children can be scalded by the hot water, so that safety accidents are caused.

Disclosure of Invention

In order to make up for the defects of the prior art, the vacuum cup solves the problems that when a child uses the vacuum cup, the child drinks water urgently due to poor patience of the child, and if the temperature of hot water in the vacuum cup is too high, the child is scalded by the hot water, so that safety accidents are caused; the invention provides a vacuum cup.
