[0021] In order to more clearly and completely illustrate the technical solution of the present utility model, the present utility model will be further described below with reference to the accompanying drawings.
[0022] As Figures 1 - 4 shown, an embodiment of the present utility model proposes a portable heat-insulating and heat-preserving three-dimensional bag for daily use, including a heat-preserving bag 1. The overall material of the heat-preserving bag 1 is non-woven fabric. A aluminized film is provided on the inner side of the heat-preserving bag 1. First self-sealing bone strips 2 and second self-sealing bone strips 3 are fixedly connected to the inner walls of both sides of the heat-preserving bag 1 near the bag mouth. The first self-sealing bone strip 2 and the second self-sealing bone strip 3 are used in cooperation with each other. Handles 4 are fixedly installed on both sides of the outside of the heat-preserving bag 1. The aluminized film inside the heat-preserving bag 1 has good heat reflection characteristics and the barrier effect of nano-bubbles on air heat convection, which can avoid the heat loss inside the heat-preserving bag 1. At the same time, through the first self-sealing bone strip 2 and the second self-sealing bone strip 3 arranged at the mouth of the heat-preserving bag 1, when the first self-sealing bone strip 2 and the second self-sealing bone strip 3 are buckled, it can play a good airtight effect on the heat-preserving bag 1, further reducing heat loss. At the same time, a portable handle 4 is provided on the heat-preserving bag 1, which is more convenient to use when shopping in daily life and convenient to carry by hand.
[0023] As Figure 2 shown, magnets 5 are fixedly connected to the opposite sides of the first self-sealing bone strip 2 and the second self-sealing bone strip 3. The magnets 5 on the first self-sealing bone strip 2 and the second self-sealing bone strip 3 are symmetrically arranged. When the first self-sealing bone strip 2 and the second self-sealing bone strip 3 are buckled, first, the magnets 5 on the first self-sealing bone strip 2 and the second self-sealing bone strip 3 are adsorbed to each other, so that the first self-sealing bone strip 2 and the second self-sealing bone strip 3 are close to each other. Then, the first self-sealing bone strip 2 and the second self-sealing bone strip 3 are groped and pressed, so that the first self-sealing bone strip 2 and the second self-sealing bone strip 3 are buckled, which is more convenient.
[0024] As Figure 1 shown, a cover plate 6 is fixedly connected to one side of the heat-preserving bag 1. The material of the cover plate 6 is non-woven fabric. An aluminized film is provided on the side of the cover plate 6 facing the heat-preserving bag 1. When the first self-sealing bone strip 2 and the second self-sealing bone strip 3 are buckled, the cover plate 6 is flipped so that the cover plate 6 covers above the first self-sealing bone strip 2 and the second self-sealing bone strip 3 to block the gap and reduce the heat loss of hot cooked food or the cold air of frozen products.
[0025] As Figure 1 and Figure 3 shown, a first magic tape 7 is provided between the cover plate 6 and the heat-preserving bag 1.
[0026] As Figure 1 and Figure 3As shown in the figure, the first magic tape 7 includes a first fiber patch 71 and a first hook patch 72. The first fiber patch 71 is fixed on the side of the cover plate 6 facing the insulation bag 1, and the first hook patch 72 is fixed on the outer side of the insulation bag 1 away from the cover plate 6. After the cover plate 6 is flipped and covered on the first self-sealing bone strip 2 and the second self-sealing bone strip 3, the first fiber patch 71 and the first hook patch 72 are adhered together to fix the cover plate 6 and prevent the cover plate 6 from reversing and moving away from above the first self-sealing bone strip 2 and the second self-sealing bone strip 3 when moving.
[0027] As Figure 4 shown, partition components 8 are provided on the side walls on both sides inside the insulation bag 1.
[0028] As Figure 3 and Figure 4 shown, the partition component 8 includes a partition board 81. The material of the partition board 81 is non-woven fabric. The partition board 81 is fixedly connected to the insulation bag 1. Aluminum-plated films are provided on both sides of the partition board 81. A second magic tape 9 is provided between the partition board 81 and the insulation bag 1. The second magic tape 9 includes a second fiber patch 91 and a second hook patch 92. The second fiber patch 91 is fixedly connected to the partition board 81, and the second hook patch 92 is fixedly connected to the insulation bag 1.
[0029] As Figure 4 shown, two partition components 8 in the insulation bag 1 are arranged staggeredly. The second magic tapes 9 between the two partition boards 81 and the insulation bag 1 can be adhesively used with each other. When frozen products and hot cooked foods need to be placed in the insulation bag 1, in order to prevent them from directly contacting each other and affecting each other, at this time, tear open the two partition boards 81 to pull out the partition boards 81 originally attached to the inner wall of the insulation bag 1 and stick them on the second hook patches 92 on the opposite side. The height of the partition board 81 is the same as the depth of the insulation bag 1, and the insulation bag 1 is divided into three parts. At this time, place the frozen products and hot cooked foods in the areas on both sides respectively, and place other items in the middle part to separate the frozen products and hot cooked foods to avoid affecting each other, resulting in the melting of the frozen products and the cooling of the hot cooked foods. At the same time, the partition board 81 is also provided with an aluminum-plated film, which can delay the thawing of the frozen products and at the same time delay the cooling of the hot cooked foods.
[0030] Working principle: The aluminized film inside the thermal insulation bag 1 can prevent the heat inside the thermal insulation bag 1 from dissipating. At the same time, through the first self-sealing bone strip 2 and the second self-sealing bone strip 3 arranged at the opening of the thermal insulation bag 1, when the first self-sealing bone strip 2 and the second self-sealing bone strip 3 are buckled, first, the magnets 5 on the first self-sealing bone strip 2 and the second self-sealing bone strip 3 adsorb each other, making the first self-sealing bone strip 2 and the second self-sealing bone strip 3 approach each other. Then, grope and press the first self-sealing bone strip 2 and the second self-sealing bone strip 3, flip the cover plate 6, so that the cover plate 6 covers above the first self-sealing bone strip 2 and the second self-sealing bone strip 3, and adhere the first fiber sticker 71 and the first prickly sticker 72 together to fix the cover plate 6. When frozen products and hot cooked foods need to be placed in the thermal insulation bag 1, in order to prevent them from directly contacting each other and affecting each other, at this time, tear open two partition boards 81 and stick them on the second prickly stickers 92 on the opposite side. The height of the partition board 81 is the same as the depth of the thermal insulation bag 1, and the thermal insulation bag 1 is divided into three parts. At this time, place the frozen products and hot cooked foods in the areas on both sides respectively, and place other items in the middle part to separate the frozen products and the hot cooked foods.
[0031] Certainly, the present utility model can also have many other implementation manners. Based on this implementation manner, other implementation manners obtained by ordinary technical personnel in the field without any creative labor belong to the scope protected by the present utility model.
