Abstract
The utility model discloses a double-layer vacuum pure titanium electric heating cup, which comprises a cup body, a cup mouth, an outer shell, a connecting ring, an inner shell and a cup bottom, the bottom of the outer shell is provided with the connecting ring, the connecting ring is connected with the bottom of the inner shell, the cup bottom is arranged inside the lower end of the inner shell, and the cup mouth is connected with the inner shell. The outer shell, the connecting ring, the inner shell and the cup bottom are all made of pure titanium metal materials, and the connecting ring and the bottom of the cup inner container are in a micro-horn shape. According to the double-layer vacuum pure-titanium electric heating cup, the horn-shaped connecting ring is designed to be matched with annular welding at the bottom of the inner container, so that the outer shell and the inner shell form a stable sealed cavity, heat loss is effectively blocked, and the heat preservation effect is improved; the cup bottom is integrally connected with the inner shell through laser welding, so that the pressure resistance of the bottom is enhanced, a heat conduction path is optimized, and the heating efficiency is improved; and thirdly, multiple sealing guarantees are constructed through the double welding technology, the hidden danger of water leakage is eradicated, meanwhile, the overall rigidity of the structure is enhanced, and the use safety and stability under the electric heating scene are ensured.
