Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 3 In an embodiment of the utility model, a self-sealing heat preservation bag comprises a box body 1, a top end of the box body 1 is connected to an upper cover 2 for sealing the upper end of the box body 1, and a heat preservation mechanism 3 is arranged on the box body 1 and the upper cover 2, and the heat preservation mechanism 3 is used to further increase the heat preservation effect of the upper cover 2 and the box body 1;

[0028] The heat preservation mechanism 3 includes a heat preservation unit and a sealing unit;

[0029] The heat preservation unit is used to further increase the heat preservation effect of the box body 1 and the upper cover 2;

[0030] The sealing unit is used to synchronously open the connection between the box body 1, the upper cover 2 and the heat preservation unit;

[0031] The heat preservation unit includes a lower heat preservation layer 302, an upper heat preservation layer 303, and a connecting rope 304;

[0032] The lower insulation layer 302 is fixed inside the box body 1, and the lower insulation layer 302 is used to cooperate with the upper insulation layer 303 to increase the insulation effect of the box body 1;

[0033] The upper insulation layer 303 is fixed to the rotating end of the upper cover 2 and the box body 1, and the upper insulation layer 303 is used to seal the upper part of the lower insulation layer 302;

[0034] The connecting rope 304 is fixed to the inner side of the upper cover 2 and the outer wall of the upper insulation layer 303, and the connecting rope 304 is used to synchronously drive the upper insulation layer 303 to move;

[0035] The sealing unit includes a zipper head 301, a chain 305, and a magnetic strip 306;

[0036] The chain 305 is fixed to the top outer wall of the box body 1 and the upper cover 2, and the chain 305 is used to provide a limit for the connection between the box body 1 and the upper cover 2;

[0037] The magnetic strip 306 is fixed to the top outer wall of the upper insulation layer 303 and the lower insulation layer 302, and the magnetic strip 306 is used to provide a connecting force for the upper insulation layer 303 and the lower insulation layer 302;

[0038] The zipper head 301 is slidably mounted on the outer wall of the chain 305 and the magnetic strip 306 , and the zipper head 301 is used to provide guidance for the connection between the chain 305 and the magnetic strip 306 ;

[0039] A gap is provided between the box body 1 and the upper cover 2 to further increase the heat preservation effect.

[0040] In this embodiment, when the device is used, by applying a pulling force to the zipper head 301, the zipper head 301 subjected to the force will move along the connection between the box body 1 and the upper cover 2, and the moving zipper head 301 will synchronously move between the chain 305 and the magnetic strip 306, releasing the connection between the chain 305 located above and below the box body 1 and the upper cover 2, and the movement of the zipper head 301 will also synchronously separate the magnetic strips 306 located above and below, so that the magnetic strips 306 located above and below are separated by the force from the zipper head 301.
