Description

Technical Field

[0001] The utility model belongs to the field of daily necessities production, in particular to a heat insulation cover and a heat preservation device. Background Art

[0002] Common thermal insulation devices currently on the market generally use insulating plugs for insulation. Insulating plugs are mostly made of cork, plastic or silicone to prevent the heat of the thermal insulation device from dissipating from the bottle mouth. For the bottle body of the thermal insulation device, vacuum double-layer glass or metal is often used to prevent heat loss. Since insulating plugs made of cork and other materials can only insulate the opening of the bottle mouth, but do not insulate the outside of the bottle mouth to prevent heat dissipation from the inside to the outside along the side wall of the bottle mouth, the thermal insulation effect is poor. At the same time, bottle plugs made of cork and other materials do not fit tightly enough with the bottle mouth of the thermal insulation device during use, which not only has a poor thermal insulation effect but is also prone to plug jumping. In addition, unsafe substances are easily precipitated during use. Bottle plugs made of silicone plastic have poor thermal insulation effect and become the main heat loss component of the thermal insulation device. Utility Model Content
