Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to the attached drawings 1-5, the heat preservation bag comprises a bag body 1 and a heat preservation layer 2, wherein a containing cavity 10 is arranged in the bag body 1, and the heat preservation layer 2 is coated on the inner wall of the containing cavity 10.

Specifically, the heat preservation layer 2 is internally provided with a cold accumulation substance, and the heat preservation bag is provided with: a first state in which the cavity 10 is opened and a second state in which the cavity 10 is closed; when a user uses the heat preservation bag to keep fresh and freeze food, the heat preservation bag is placed in a refrigerator to be frozen for a period of time no matter the heat preservation bag is in the first state or the second state, so that the temperature of the heat preservation layer is lower than the normal temperature; then, taking the thermal insulation bag out of the refrigerator, enabling the thermal insulation bag to be in a first state, and then placing food into the accommodating cavity 10; finally, the heat preservation bag is switched from the first state to the second state, external hot air is prevented from entering the accommodating cavity 10, the temperature loss of frozen food is slowed down through the low-temperature effect of the heat preservation layer, and the cold preservation effect is achieved.

Further, as shown in fig. 3-5, in the present invention, the heat insulating layer 2 includes a pearl cotton layer 20, a freezing gel ice bag 21 and an EVA layer 22, the pearl cotton layer 20 is attached to the inner wall of the cavity 10, the freezing gel ice bag 21 is located between the pearl cotton layer 20 and the EVA layer 22, and the EVA layer 22 wraps the freezing gel ice bag 21 and the pearl cotton layer 20; the pearl wool layer 20 is used for isolating the outside temperature, so that the temperature of the frozen gel ice bag 21 can be slowed down to be transferred to the outside, and the temperature loss speed of the frozen gel ice bag 21 is reduced; meanwhile, the temperature of the frozen gel ice bag 21 is transferred into the cavity 10, so that the temperature inside the cavity 10 is reduced, and the cold insulation effect is achieved.

It should be noted that the wrapping of the EVA layer 22 also plays a role in leakage prevention, so as to prevent the food juice from permeating into the bag body 1 when leaking into the cavity 10, which may cause leakage; it should be noted that the contents of the frozen gel ice bag 21 are in a liquid state at normal temperature, and the longer the thermal insulation pack is placed in the refrigerator for freezing, the lower the temperature of the frozen gel ice bag 21 is, and the better the cooling effect of the thermal insulation pack is. When the frozen gel ice bag 21 is condensed from a liquid state to a solid state, a better freezing and heat preservation effect can be achieved; if the heat preservation bag is not placed in a refrigerator for freezing, the pearl cotton layer 20 has a certain heat preservation effect at normal temperature, and can be applied to heat preservation of food.

Furthermore, in order to fix the position of each layer such as the cotton layer 20 of pearl, freezing gel ice bag 21 and EVA layer 22, avoid the aversion of each layer to lead to the heat preservation effect variation, as shown in fig. 3-5, the utility model discloses in, cotton layer 20 of pearl, freezing gel ice bag 21 and EVA layer 22 all adopt sutural mode fixed connection on holding the intracavity 10 inner wall.

Furthermore, in order to facilitate the storage and taking of food, as shown in fig. 1-2, in the present invention, the bag body 1 includes a bag body 11 and a bag cover 12, the cavity 10 is disposed in the bag body 11 and has an opening, the bag cover 12 is connected to the bag body 11, and the bag cover 12 can open or cover the opening of the cavity 10; the insulating layer 2 is respectively coated on the inner wall of the containing cavity 10 of the ladle body 11 and the bottom of the ladle cover 12.

It should be noted that, when the cover 12 covers the opening of the cavity 10 and encloses a closed cavity for storing food, a bag is further disposed at the bottom of the cover 12 to prevent the food in the closed cavity from being mixed.

Further, in order to increase the storage space of the thermal insulation bag and prevent tableware and food from being mixed in the cavity 10, as shown in the attached drawings 1-2, both sides of the bag body 1 of the utility model are also provided with storage bags 3; meanwhile, the top of the bag cover 12 is also provided with a storage bag, and a zipper is arranged at the opening of the storage bag to open or close the opening, so that articles in the storage bag are prevented from falling out, and the storage space of the heat preservation bag is further improved.

Furthermore, considering that the bag body 1 and the bag cover 12 have good flexibility to increase the comfort of the user when in use, as shown in the attached drawings 1-5, the bag body 1 is made of fabric.

Furthermore, in order to facilitate the carrying of the thermal insulation bag by the user, as shown in the attached drawings 1-3, the utility model discloses in, still include the hand ring 4, the hand ring 4 is installed at the top of the bag body 1.
