Title:
VACUUM CUP COVER STRUCTURE AND VACUUM CUP
Document Type and Number:
WIPO Patent Application WO/2021/120267
Kind Code:
A1
Abstract:
A vacuum cup cover structure and a vacuum cup. The vacuum cup cover structure comprises a stainless steel double-layer vacuum part (8), a honeycomb interlayer (7), a stainless steel outer cover layer (2) and a plastic layer (4), wherein the stainless steel double-layer vacuum part (8) comprises a first heat preservation interlayer, a containing groove is formed above the first heat preservation interlayer, the honeycomb interlayer (7) is arranged in the containing groove to form a second heat preservation interlayer, the stainless steel outer cover layer (2) covers the containing groove to form a closed space, and the plastic layer (4) is wrapped around the side face of the stainless steel double-layer vacuum part (8). The first heat preservation interlayer of the stainless steel double-layer vacuum part (8) cooperates with the honeycomb interlayer (7) contained in the containing groove above the first heat preservation interlayer, and heat passing through the first heat preservation interlayer is transmitted back by means of the honeycomb interlayer (7) after entering the honeycomb interlayer (7), thereby preventing heat conduction loss; and the stainless steel double-layer vacuum part (8) is wrapped by the plastic layer (4), such that heat is prevented from being conducted out of the outer layer of the stainless steel double-layer vacuum part (8), and a better heat preservation effect can be achieved.
