[0001] The utility model relates to the technical field of airtight insulation bags, in particular to a novel airtight insulation bag. Background Art
[0002] The insulation bag is a bag used to store food. It is a type of outdoor bag used to hold various foods, medicines, or items that are easily deformed by temperature. It can be used to keep heat or cold, and maintain the temperature or freshness of food. Its main function is to reduce the impact of ambient temperature on the food inside the insulation bag.
[0003] Based on the above, the existing airtight insulation bags usually use electronic components inside the insulation bags to measure the temperature inside the insulation bags during use. However, since the insulation bags are often mixed with some moisture during the process of storing food, and the electronic components are used in a water-containing environment for a long time, water vapor will penetrate into the electronic components, which can easily damage the electronic components. At the same time, since the existing airtight insulation bags need to observe the remaining materials inside the bag, the insulation bag body is usually opened to observe the internal materials, which will allow external air to enter the insulation bag, so that the temperature inside the insulation bag is affected and lowered, thereby reducing the insulation effect of the insulation bag.

[0034] In this embodiment, the outer cover of the airtight insulation bag 1 is made of MPR material and TPU material in a 1:1 ratio, which is pressed and welded, and has IPX7 waterproof performance. With the help of the heat resistance, corrosion resistance and insulation performance of the MPR material and the wide hardness range and high mechanical strength of the TPU material, the airtight insulation bag 1 has the advantages of high strength, good wear resistance, heat resistance and corrosion resistance, which increases the service life of the airtight insulation bag 1. The inner liner of the airtight insulation bag 1 is made of PE polymer material, which makes the airtight insulation bag 1 have good insulation effect and can keep the materials inside the backpack warm for 48 hours.
[0035] In this embodiment, both the handle strap 3 and the backpack strap 4 enable the user to carry the airtight insulation bag 1 in a portable manner. The handle strap 3 can manually lift the airtight insulation bag 1, and the backpack strap 4 can carry the airtight insulation bag 1 on the user's shoulders. The user can make his or her own choice based on actual usage, thereby increasing the practicality of the backpack.
[0036] In this embodiment, the perspective window 2 adopts a three-layer insulation layer design, which is composed of an outer layer 21, a vacuum layer 22 and an inner layer 23. The outer layer 21 and the inner layer 23 are both made of transparent TPU layer material, allowing the user to observe the internal materials through the outside of the backpack.
[0037] In this embodiment, a temperature measuring paper 231 is installed at the front end of the inner layer 23 near the outer layer 21. The principle of the temperature measuring paper 231 is the thermal sensitive effect. The internal temperature is observed by observing the color change caused by the oxidation-reduction reaction of the chemical substances in the temperature nodes located on the temperature measuring paper 231 under temperature changes. This allows the user to intuitively observe the temperature inside the airtight insulation bag 1 from the outside, without having to open the airtight insulation bag 1.
[0038] In this embodiment, a fluorescent powder 221 is additionally provided in the inner circle of the vacuum layer 22.

The airbags 41 installed on the backpack straps 4 can relieve the force on the user's shoulders when the backpack is carried on the user's shoulders, so that the user can feel comfortable.
[0045] The perspective window 2 on the airtight insulation bag 1 is made of a transparent TPU layer material, so that the user can observe the internal material conditions through the outside, and the temperature measuring paper 231 located on the inner layer 23 of the perspective window 2 can observe the internal temperature through the color change caused by the oxidation-reduction reaction of the chemical substances in the temperature nodes on the temperature measuring paper 231 under the temperature change, so that the airtight insulation bag 1 does not need to be opened;
[0046] When the user uses it at night, the light reflected outward from the surface of the reflective strip 31 of the outer circle of the perspective window 2 can be perceived by the eyes, so that the user can warn passing vehicles and pedestrians when walking with the backpack at night, which increases the safety of the user when using it. The inner circle of the vacuum layer 22 is additionally provided with fluorescent powder 221. With the help of the fluorescent effect of the fluorescent powder 221, the user can observe the remaining materials inside the airtight insulation bag 1 through the night light generated by the fluorescent powder 221 when using the backpack at night.
