Compared with the heat insulation material, the vacuum heat insulation layer has lower heat conductivity coefficient, the heat conductivity coefficient can be as low as 0.004W/(m.K) by reducing the heat transfer caused by air by reducing the vacuum degree, and the heat conductivity coefficient of the common heat insulation material rock wool is 0.033-0.046W/(m.K), so that the heat insulation effect of the vacuum heat insulation layer and the heat insulation material rock wool is high.
The inner container of the thermos cup commonly used in the market is a stainless steel inner container, and the stainless steel inner container can not hold acidic beverages such as lemon juice, plum juice and the like, otherwise, the stainless steel inner container can be damaged. The application range of the stainless steel is affected due to the specificity of the stainless steel. The ceramic liner has stable property, but the thinner ceramic wall cannot bear the huge pressure formed by the atmosphere after the vacuum pumping, and is extremely easy to break, so the problem that the ceramic liner is not pressure-resistant is urgent.

Further, one end of the supporting framework is connected with the main framework, and the other end of the supporting framework is connected with the inner wall of the outer ceramic layer.
Furthermore, one side of the main framework, which is not provided with the supporting framework, is tightly attached to the outer wall of the inner ceramic layer.
The main framework is a plurality of strip-shaped or column-shaped hard supporting bodies which are attached to the outer wall of the inner ceramic layer, and starts from the upper edge of the cup mouth, extends to the cup bottom, meets at the center of the cup bottom, and extends to the upper edge of the cup mouth at the other end to terminate.

Further, the outer ceramic layer and the inner ceramic layer are sealed at the cup opening.
The cup opening is glazed, and the ceramic edge is sealed.
Further, the main framework and the supporting framework are both made of heat insulation materials. Ceramic fibers are preferred.
The heat insulating material is directly connected with the inner ceramic layer and the outer ceramic layer, and is selected to avoid forming a heat channel, and the ceramic fiber has lower heat conductivity coefficient and excellent compression resistance and folding strength.
Working principle: the main framework and the supporting framework are installed on the inner wall of the outer ceramic layer, the supporting framework is connected with the inner wall of the outer ceramic layer, then the inner ceramic layer is placed on the main framework, the main framework is completely attached to the outer wall of the inner ceramic layer to play a supporting role, then a gap between the inner ceramic layer and the outer ceramic layer is vacuumized at a cup mouth, the cup mouth is sealed and glazed, a heat-insulating material is placed inside the cup cover, the cup cover is sealed, the cup cover is placed on the cup mouth, and the cup cover is completely matched with the cup mouth.
The beneficial effects of the utility model are as follows:
(1) The utility model does not use stainless steel materials, expands the application range of the vacuum cup, and solves the problem of non-pressure resistance of ceramics.
(2) According to the utility model, the main framework and the supporting framework are matched to support the outer ceramic layer and the inner ceramic layer, so that the ceramic can bear vacuum negative pressure to form the vacuum heat insulation layer, the supporting framework only forms fewer heat passages between the outer ceramic layer and the inner ceramic layer, and the supporting framework is made of ceramic fibers, so that heat transfer on the formed passages is reduced, and a good heat insulation effect is achieved.
(3) The heat insulation material is arranged in the cup cover, so that heat exchange between the top of the cup and the outside is prevented.
