AI Technical Summary
The existing ice packs have heat exchange at the seam between the lid and the body after closing, and the existing baffles have limited shielding effect, resulting in poor insulation.
An adjustment cavity is set inside the lid of the ice pack, and a sliding sealing cover is connected. The movement of the sealing cover is controlled by the cooperation of the adjustment knob and the adjustment screw. The sealing cover is made of heat-insulating material and has a sealing ridge on the outside of the sealing cover to fit tightly against the inner wall of the box. The box and the lid are equipped with corresponding sealing structures to improve the sealing performance.
This effectively reduces heat exchange between the inside and outside of the box, improving the insulation performance of the ice pack.
