[0017] This invention provides a portable cooling box that can be used in daily commuter lunch boxes, in car environments, and for outdoor camping and picnics, meeting the need for portable cooling and providing users with convenience and excellent cooling effects.

[0018] Referring to Figure 1 and Figure 2, the above is a portable cooling box.

[0019] The portable cooling box includes a body 10 having a substantially flat, sealed structure, and a refrigerant (not shown) filled in the body 10.

[0020] In this embodiment, by providing a flat sealed body 10, the shape is compact and occupies less space, and at the same time, the sealed structure makes the cooling box suitable for use in an exercise environment and is not limited to fixed scenes, thereby improving the scalability of the cooling box.

[0021] Furthermore, the body 10 includes a first flat plate 11 and a second flat plate 12 that are spaced apart and opposed to each other, and a connecting edge 13 that connects the edges of the first flat plate 11 and the second flat plate 12. In this embodiment, the first flat plate 11 and the second flat plate 12 are specifically arranged to face each other and parallel to each other to form a flat structure, and the connecting edge 13 connects them to give the body 10 a certain thickness, making it easier to fill with refrigerant.

[0022] Furthermore, a liquid inlet hole 111 is provided near the edge of the first flat plate 11, and a corresponding plug 20 is fitted into and sealed off by the liquid inlet hole 111. In this embodiment, the provision of the liquid inlet hole 111 and the corresponding plug 20 enables liquid to be injected into the body 10. As can be understood, the plug 20 and the liquid inlet hole 111 can be configured to have a detachable fitting structure, so the liquid inlet hole 111 can also be used for draining liquid, thereby enabling liquid replacement by re-injection.

[0023] Furthermore, the body 10 and the plug 20 are made of metal, and the plug 20 is fitted into the injection hole 111 and sealed by welding. In this embodiment, the plug 20 and the body 10 are welded together to achieve a permanent sealed connection after injection. Theoretically, the refrigerant can be used for a long time under sealed conditions, which improves the structural stability of the cooling box.

[0024] Furthermore, the connecting side edge 13 includes a first connecting side edge 131 and a second connecting side edge 132 that are connectable to each other, the first connecting side edge 131 being integrally connected to the edge of the first flat plate 11, and the second connecting side edge 132 being integrally connected to the edge of the second flat plate 12. In this embodiment, the body 10 is mainly formed by combining two symmetrical parts, and the integral structure of the first connecting side edge 131 and the first flat plate 11 and the integral structure of the second connecting side edge 132 and the second flat plate 12 are similar in structure and can be batch-manufactured using the same process (for example, by pressing a flat plate material), and then the injection hole 111 is formed by drilling one of the two integral structures.

[0025] Furthermore, the first connecting side 131 and the second connecting side 132 are smoothly connected.

[0026] Furthermore, the body 10 is made of metal, and the first connecting side edge 131 and the second connecting side edge 132 are sealed and connected smoothly by welding and grinding. In this embodiment, the first connecting side edge 131 and the second connecting side edge 132 are sealed and connected by welding, and the surfaces are polished to be smooth, thereby realizing a permanent sealed connection of the body and improving the structural stability of the cooling box.

[0027] In another embodiment, the body 10 is made of metal, and a metal annular connecting band 30 is installed abutting on the inside of the connection between the first connecting side edge 131 and the second connecting side edge 132, and the first connecting side edge 131, the second connecting side edge 132, and the annular connecting band 30 are smoothly and hermetically connected by welding and grinding. It can be understood that the annular connecting band 30 may be a linear annular structure abutting on the connection gap between the first connecting side edge 131 and the second connecting side edge 132; or the annular connecting band may be a flat strip-shaped annular structure abutting on the inside of the first connecting side edge 131 and the second connecting side edge 132 to cover the connection gap; the connection gap is hermetically connected by welding, stabilizing the structure of the cooling box.

[0028] In another embodiment, the first connecting side 131 and the second connecting side 132 may be smoothly sleeve-connected via a sealing silicone rubber member. For example, a silicone ring with an I-shaped cross section may be used to seal the first connecting side 131 and the second connecting side 132 at the top and bottom, respectively, to achieve a detachable sealed structure. This eliminates the need for welding and polishing, improving assembly efficiency.

[0029] Furthermore, the first flat plate 11 and the second flat plate 12 are each formed by chamfering (0.5×45°) a rectangular structure.

[0030] Furthermore, the connecting side 13 protrudes from the edge of the first flat plate 11 and the edge of the second flat plate 12 and is smoothly connected.

[0031] Furthermore, the first flat plate 11 is provided with anti-slip protrusions 112. The anti-slip protrusions 112 are used to contact the object to be cooled or the surface of the support table to provide an anti-slip effect. Specifically, the anti-slip protrusions 112 may be configured as dot-shaped raised dots. As can be understood, in other embodiments, the anti-slip protrusions 112 may be configured as vertical stripe-shaped protrusions, horizontal stripe-shaped protrusions, wavy protrusions, etc.

[0032] Furthermore, anti-skid protrusions (not shown) are provided on the second flat plate 12. Due to the symmetry of the body, the specific structure of the anti-skid protrusions provided on the second flat plate 12 can refer to the structure of the anti-skid protrusions 112 on the first flat plate 11, and will not be described again here.

[0033] Furthermore, this embodiment provides a preferred example of the dimensions of the body 10 and the selection of a refrigerant.

[0034] Specifically, the height of the body 10 is 1.0 cm to 1.5 cm.

[0035] Specifically, the length of the body is 16 cm to 18 cm.

[0036] Specifically, the width of the body is 10 cm to 12 cm.

[0037] Specifically, the coolant is selected from the group consisting of an ethylene glycol solution in water, a fluoroynote liquid, mineral oil, and deionized water.

[0038] Specifically, the weight of the refrigerant is 184 g to 186 g.

[0039] The portable cooling box provided by this invention has a flat body 10, which is sealed and filled with a refrigerant, resulting in a slim profile, excellent portability, and ease of use, as well as a simple structure and stable cooling effect.It can be used in a variety of environments, such as for sports, in-car environments, outdoor camping and picnics, and carrying lunch to work, providing users with high versatility and improving usability.

[0040] Although the present invention has been described above based on the preferred embodiment, it goes without saying that the present invention is not limited to such embodiment. Those skilled in the art will understand that various modifications and improvements can be made to the present invention without departing from the spirit and scope of the present invention, and that such modifications and improvements are within the technical scope of the present invention. The technical scope of the present invention is defined by the claims.
