In order to realize the purpose of the utility model, a can dismantle heat preservation device, it includes:

a backpack body;

the heat-preservation bag is detachably arranged at the bottom of the backpack body;

the buckle assembly comprises a plurality of buckle female heads and a plurality of buckle male heads, the buckle female heads are arranged at the edge of the bottom of the backpack body, the buckle male heads are arranged at the outer edge of the upper end surface of the heat-preservation bag, and each buckle male head is matched with the corresponding buckle female head;

the heating unit and/or the refrigerating unit are arranged on the inner side of the bottom of the heat-preservation bag and are powered by an external direct-current power supply.

Further, the heat-preservation bag comprises a heat-preservation interlayer, and the heat-preservation interlayer sequentially comprises a nylon cloth outer layer, a sponge filling layer and a tin foil inner layer from outside to inside.

Further, the heat preservation bag includes flexible bag body and adaptation in the flexible flip of flexible bag body.

Furthermore, the backpack body also comprises a side bag arranged on the side surface, and the side bag is provided with another heat-preservation interlayer.

Compared with the prior art, implement the beneficial effects of the utility model reside in that:

(1) the heat preservation bag with the detachable heating unit and/or the detachable refrigerating unit is additionally arranged, so that the lunch box can be placed at the lower part of the knapsack, the hand of a user who originally holds the lunch box is liberated, and the heat preservation bag has the heating and/or refrigerating heat preservation effect, so that the experience of the user when eating food is improved;

(2) simple structure is convenient for operate, and the detachable connection mode that uses buckle and/or zip fastener subassembly setting is very general, easy implementation.
