Description

Technical Field

[0001] This utility model relates to the field of thermal insulation barrel technology, and in particular to an energy storage thermal insulation barrel. Background Technology

[0002] An energy storage and insulation container is a device that integrates energy storage and insulation functions. It can store thermal or cold energy and maintain the stable temperature of internal materials without the intervention of external energy sources. It has a wide range of applications and locations.

[0003] Existing energy storage insulated containers, such as CN217806298U, disclose a flat-lid insulated container, proposing the following solution: it includes an insulated container body and an insulated container lid. An inflatable sealing component replaces the rubber sealing ring to seal the container body and lid, enhancing the sealing effect and preventing excessive heat loss. Simultaneously, the double-layer design of the container body and the vacuum inner liner minimizes the heat conduction path of the object to be insulated within the vacuum inner liner, maximizing insulation. Existing insulated containers use downward pressure applied to the lid to inflate the sealing bladder and compress the sealing ring. However, this structure suffers from limited downward pressure from the lid, resulting in insufficient gas filling of the bladder and ultimately poor sealing. Furthermore, in some special application scenarios, the bottom of the insulated container is not stable enough, potentially causing it to tip over upon impact, spilling contents or even deforming the outer wall.

[0004] Therefore, those skilled in the art urgently need to provide an energy storage and insulation barrel with better sealing performance and an added stabilizing device at the bottom of the barrel. Utility Model Content
