The utility model discloses a multi-layer cooling ice pack, which comprises a first soft rubber layer, a second soft rubber layer and a third soft rubber layer arranged in sequence, and the first soft rubber layer and the second soft rubber surround to form a first accommodation space , the second soft glue layer and the third soft glue surround the second accommodation space, the back of the first soft glue layer is fixed with the first heat insulation layer, and the front of the second soft glue layer is fixed with the second heat insulation layer. The utility model can allow the first storage space to exchange liquid with the second storage space, thereby reducing the temperature of the second storage space, so that the second storage space can continue to maintain a low-temperature working state, thereby improving the overall use time. |
