Description

Technical Field

[0001] The utility model relates to the technical field of food insulation foam boxes, in particular to a novel double-layer food insulation foam box. Background Art

[0002] Insulated food foam boxes play a vital role in modern life, particularly in the transportation and storage of food, beverages, seafood, and pharmaceutical products. These boxes are made of polystyrene foam (EPS), whose unique physical properties give them exceptional insulation. EPS is not only lightweight but also has extremely low thermal conductivity, meaning it effectively blocks heat transfer, thus maintaining a relatively stable temperature within the box.

[0003] However, despite their excellent insulation performance, EPS foam boxes also have certain limitations. Existing foam boxes rely primarily on the thermal insulation properties of the foam material itself to maintain internal temperature, which means they may not always maintain ideal insulation when faced with drastic changes in the external environment. For example, in extremely high or low temperature environments, the temperature inside the foam box may fluctuate accordingly, which may bring certain risks to products that are extremely sensitive to temperature (such as certain medicines and fresh foods). Currently, no effective solution has been proposed to address the problems in related technologies. Utility Model Content

[0006] A novel double-layer food insulation foam box includes a foam box body, a connecting cover is provided above the foam box body, a fixing mechanism is provided between the foam box body and the connecting cover, the foam box body includes an inner foam board and an outer foam board, and an insulation mechanism is provided inside the inner foam board.

[0007] Furthermore, in order to enhance the insulation effect of this food insulation foam box, the insulation mechanism includes grooves arranged on the inner foam board, the number of the grooves is four, a phase change material box is arranged inside the groove, the phase change material box is provided with a phase change material, a sealing cover is provided above the phase change material box, the sealing cover and the phase change material box are connected by bolts, the number of bolts is two, and a pull plate is provided on the sealing cover.

[0008] Furthermore, in order to facilitate the disassembly of the phase change material box, there are two pull plates, each of which is provided with an opening, and the connecting cover is provided with a positioning groove, which matches the pull plate.

[0009] Furthermore, in order to ensure that the box cover fits tightly to the box body, reduce the circulation of external air, and improve the thermal insulation effect, the fixing mechanism includes a fixing seat arranged on both sides of the connecting cover, a slide groove is provided at the bottom end of the fixing seat, and a card block is provided inside the slide groove. There are two card blocks, and the two card blocks are connected by a spring. A card groove is provided on the outside of the outer foam board, and the card block matches the card groove.

[0010] Furthermore, in order to limit the moving distance of the card block and ensure the fixing effect of the card block, a limit groove is provided on the outside of the slide groove, and a limit plate is provided inside the limit groove, and one end of the limit plate is connected to the card block.

[0011] Furthermore, in order to prevent external pollution sources from entering the interior of the thermal insulation box, an antibacterial layer is provided on the outer surface of the outer foam board and the connecting cover, and the antibacterial layer is a silver ion coating.

[0012] Furthermore, the phase change material box is made of polyethylene plastic.

[0015] (2) By setting up a fixing mechanism, the box cover is ensured to fit tightly to the box body, reducing the circulation of external air and improving the insulation effect. When the connecting cover is placed on the foam box body, the card block in the fixing mechanism will be accurately connected to the inside of the card slot on the outer foam board. This card connection method is not only simple and convenient, but also can firmly fix the connecting cover to prevent it from accidentally opening due to bumps or vibrations during handling or transportation. In this way, it can not only ensure the safety of the items in the box and prevent them from being damaged by accidentally opening the box cover, but also improve the reliability of the entire transportation process and reduce potential losses and risks.

A limit groove 8 is provided on the outside of the slide groove 302, and a limit plate 7 is provided inside the limit groove 8. One end of the limit plate 7 is connected to the card block 303. An antibacterial layer 9 is provided on the outer surface of the outer foam board 102 and the connecting cover 2. The antibacterial layer 9 is a silver ion coating. By providing the antibacterial layer 9, it is possible to prevent external pollution sources from entering the interior of the insulation box. The constituent material of the phase change material box 402 is polyethylene plastic.

[0027] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0028] In actual application, the phase change material box 402 is filled with special phase change materials. These materials have the ability to absorb and release heat within a certain temperature range. This property enables them to absorb or release heat through their own phase change process (i.e., from solid to liquid or from liquid to solid) when the temperature inside the insulated box changes, thereby helping the insulated box maintain a stable internal temperature. When the external ambient temperature rises, the phase change material will absorb excess heat to prevent the temperature inside the box from being too high; and when the external ambient temperature drops, the phase change material will release the stored heat to ensure that the temperature inside the box is not too low and that the temperature inside the box is not greatly affected. When the phase change material inside the phase change material box 402 needs to be replaced, the pull plate 405 can be pulled to pull the phase change material box 402 out of the groove 401, and then the bolts 404 connecting the sealing cover 403 to the phase change material box 402 can be removed to replace the phase change material inside the phase change material box 402. 03 is removed, so that the phase change material can be replaced, and when the connection cover 2 needs to be covered on the foam box body, the limit plate 7 is moved to drive the block 303 to move, and then by loosening the limit plate 7, under the action of the spring 304, the block 303 will be placed inside the card slot 305, which can fix the connection cover 2 to prevent it from accidentally opening due to bumps or vibrations during handling or transportation, and when the connection cover 2 needs to be disassembled, the limit plate 7 is moved again to make the block 303 away from the card slot 305, so that the connection cover 2 can be disassembled.

[0029] In summary, with the aid of the above-mentioned technical solution of the present invention, by providing the heat preservation mechanism 4, the phase change material can absorb or release heat within a certain temperature range, thereby helping the foam box maintain a stable internal temperature. When the external ambient temperature changes, the phase change material can buffer the temperature fluctuation through the phase change process, ensuring that the temperature inside the box is not significantly affected. The phase change material can also be recycled multiple times, thereby reducing the need for frequent replacement of the heat preservation material and lowering long-term maintenance costs. In addition, by providing a pull plate 405, the user can easily remove the phase change material box 402 from the heat preservation box by pulling the pull plate 405 to perform necessary replacement or maintenance operations. This design not only ensures the efficient operation of the foam box, but also improves the user experience. The fixing mechanism 3 is set to ensure that the box cover fits tightly to the box body, reducing the circulation of external air and improving the insulation effect. When the connecting cover 2 is placed on the foam box body, the clamping block 303 in the fixing mechanism 3 will accurately engage with the inner groove 305 of the outer foam board 102. This clamping method is not only simple and convenient, but also can firmly fix the connecting cover 2, preventing it from accidentally opening due to bumps or vibrations during handling or transportation. In this way, it can not only ensure the safety of the items in the box and prevent them from being damaged by accidentally opening the box cover, but also improve the reliability of the entire transportation process and reduce potential losses and risks.
