Description

Technical Field

[0001] The invention relates to the technical field of outdoor backpacks, and in particular to a backpack refrigerator. Background Art

[0002] As outdoor activities such as camping and hiking become more and more popular, the demand for portable refrigeration equipment is also growing. Traditional portable refrigeration equipment is mostly hard boxes or soft insulation bags. Although they can provide a certain cooling effect, they are not easy to carry. For example, hard boxes are large and heavy, making them difficult to carry; while soft insulation bags are light, they have poor insulation performance and it is difficult to ensure the stability of the items inside.

[0003] In order to solve the above problems, some backpack-type refrigeration equipment has appeared on the market. Although these equipments are combined with the design concept of backpacks, the existing backpack-type refrigeration equipment still has some shortcomings, such as poor sealing performance leading to cold air leakage, affecting the cooling effect; or inconvenient opening, which easily causes cold air loss during use; and the connection structure between the refrigeration equipment and the bag body is exposed, thus affecting its appearance. In addition, some backpack refrigerators have a complex connection structure between the cover body and the lower box body, and the opening method of the refrigerator is relatively cumbersome.

[0019] 2. The upper package body is connected to the lower package body through a connecting cloth strip and a zipper structure. When the zipper structure is closed, the zipper connection can tighten the upper package body so that the cover body can be more tightly covered on the lower shell body, thereby improving the sealing effect of the box body. At the same time, the upper package body and the zipper structure can completely cover the cover body, and then after the zipper structure is closed, it is difficult to see from the outside that the refrigerator is contained, thereby improving the aesthetics of the product.

[0020] 3. The first soft material is filled between the upper bag and the cover, and the second soft material is filled between the lower bag and the lower shell, which can improve the hand feel, fill the gap between the box body and the upper and lower bags, and effectively buffer the impact of the backpack refrigerator on the human body during hiking. It can also increase the thermal insulation effect of the refrigerator, reduce the heat transfer between the air and the refrigerator, and reduce power consumption.

[0021] 4. The charging socket and the power supply are shielded by the side package body, which not only improves the appearance of the product, but also isolates foreign objects from the charging socket and the power supply through the side package body, thereby protecting the charging socket and the power supply.

[0022] 5. The compressor, controller, and condenser components are located between the fan and the air outlet. The fan draws air from the front of the lower bag and blows it toward the compressor, controller, and condenser components. The heat is dissipated into the atmosphere through the air outlet on the rear side of the backpack, ensuring that the human body feels cool.

[0023] 6. A first raised portion and a second raised portion are provided on the front side of the lower enclosure to separate the back of a human body from the air inlet, thereby preventing the back of a human body from blocking the air inlet and ensuring the air intake effect.
