Description

Technical Field

[0001] This utility model relates to the field of cold chain preservation technology, specifically a preservation device for cold chain distribution. Background Technology

[0002] Cold chain logistics generally refers to a systematic project that ensures refrigerated and frozen foods are kept in a specified low-temperature environment throughout all stages from production, storage, transportation, and sales to consumption, in order to guarantee food quality and reduce food loss. It was established with the advancement of science and technology and the development of refrigeration technology. It is a low-temperature logistics process based on cryogenics and using refrigeration technology. There are three types of food storage boxes: one is a plastic food storage box, also known as a food storage container, made of resin material, with a general temperature resistance range of 120℃ to -20℃; another is a foam food storage box; and the last is a cold and heat resistant high-tech food storage box, made of food-grade environmentally friendly LLDPE material.

[0003] Currently, conventional cold chain distribution preservation devices mostly place ice blocks at the bottom of the box, causing cold air to accumulate at the bottom, resulting in freezing damage to items at the bottom. The cold air distribution is uneven, resulting in poor preservation. In addition, the boxes are relatively deep, making it inconvenient to access items in the deeper parts, which is time-consuming and laborious, reduces work efficiency, and causes a large amount of cold air to be lost, which is not conducive to use. Therefore, we have proposed a cold chain distribution preservation device to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] like Figures 1-3 As shown in the figure, an embodiment of the present invention provides a cold chain distribution preservation device, including an insulated box 1. Two partitions 2 are fixedly installed on the upper, lower and rear inner walls of the insulated box 1 at the left and right positions. The left and right partitions 2 divide the insulated box 1 from left to right into a first installation chamber 3, a placement chamber 4 and a second installation chamber 5. A blower mechanism 6 is provided in the first installation chamber 3 and the second installation chamber 5. A placement mechanism 7 is fixedly installed on the upper and lower positions between the partitions 2. The upper and lower placement mechanisms 7 divide the placement chamber 4 from top to bottom into three placement cavities 8. The two upper placement cavities 8 are used for placing insulated items, and the lower placement cavity 8 is used for placing cold source ice. The front side of the insulated box 1 corresponding to each placement cavity 8 is hinged with a box door 9.

[0025] like Figure 3 As shown, in some embodiments, the lower surface of the heat preservation box 1 is rectangularly mounted with rollers 10, the lower edge of the rear side of the heat preservation box 1 is fixedly mounted with a drain valve 11, and the upper rear side of the heat preservation box 1 is fixedly mounted with a handle 12.

[0026] In this embodiment, the rollers 10 facilitate the movement of the insulation box 1, the drain valve 11 can drain the water formed by the melting ice, and the handle 12 facilitates the movement of the insulation box 1.

[0027] like Figure 2As shown, in some embodiments, the blower mechanism 6 includes a controller 601, a battery 602, a fan 603, a ventilation hole 604, and an activated carbon adsorption plate 605. The controller 601 is embedded in the lower left side wall of the insulation box 1, and the battery 602 is installed in the lower side of the first mounting chamber 3 corresponding to the controller 601. The fan 603 is fixedly installed on the left partition 2 at the position corresponding to the lowermost placement cavity 8. Ventilation holes 604 are provided on the partition 2 at the front and back of the positions corresponding to the three placement cavities 8. The activated carbon adsorption plate 605 is placed in the second mounting chamber 5 at the position corresponding to the ventilation hole 604 on the lowermost placement cavity 8.

[0028] In this embodiment, the controller 601 is turned on, so that the battery 602 supplies power to the fan 603. The fan 603 blows the cold air in the lowest placement chamber 8 into the first installation chamber 3, and then flows into the corresponding placement chambers 8 on the upper two placement mechanisms 7 through the ventilation holes 604 on the partition 2, cooling and preserving the items. The gas in the upper two placement chambers 8 flows into the second installation chamber 5 through the ventilation holes 604 on the right partition 2. The activated carbon adsorption plate 605 in the second installation chamber 5 adsorbs the odor in the gas. The gas then flows into the lowest placement chamber 8 containing the cold source through the lowest ventilation hole 604 on the right partition 2, forming a cold air circulation and making the cold air evenly distributed.

[0029] like Figure 2 and Figure 3 As shown, in some embodiments, the placement mechanism 7 includes a roller assembly 701, a belt 702, and a handle 703. The roller assembly 701 is installed between the left and right side partitions 2 at both the front and rear. The belt 702 is sleeved between the outer surfaces of the roller assembly 701. The handles 703 are fixedly installed on the left and right input shafts of the frontmost roller assembly 701. The handles 703 are arranged in the first installation chamber 3 and the second installation chamber 5.

[0030] In this embodiment, the front roller assembly 701 is rotated by rotating the handle 703, which in turn drives the belt 702 to rotate. The rotation of the belt 702 facilitates the storage and retrieval of items on the upper surface of the belt 702.

[0031] like Figure 3 As shown, in some embodiments, the side of the belt 702 is movably fitted to the front and rear inner walls and the left and right side partitions 2 of the insulated box 1, respectively.

[0032] In this embodiment, the belt 702 has a good sealing effect with the front and rear inner walls and the left and right side partitions 2 of the insulated box body 1, preventing items from entering.

[0033] like Figure 1As shown, in some embodiments, the cabinet door 9 is locked and fixed to the insulated cabinet body 1 by a concealed lock 13.

[0034] In this embodiment, the door 9 of the concealed lock 13 cannot be opened at will.

[0035] like Figure 3 As shown, in some embodiments, a rectangular opening 14 is provided on the front side wall of the insulated box 1 corresponding to the box door 9.

[0036] In this embodiment, the rectangular opening 14 facilitates the placement of items into the placement cavity 8.

[0037] In use, open the bottommost door 9 and place the cold source (such as ice) into the bottommost placement chamber 8. Lock the bottommost door 9 to the insulated box 1 using the concealed lock 13. Depending on the needs, open the corresponding door 9 of the upper placement mechanism 7 and place the items to be kept fresh on the upper surface of the belt 702 in the placement mechanism 7. Pushing the placed items will cause the belt 702 to rotate on the roller assembly 701, thus moving the items to the rear of the insulated box 1. Conversely, pushing the belt 702 will move the items from the rear of the insulated box 1 forward, facilitating placement. Alternatively, the handle 703 can be used to rotate the roller assembly 701, which in turn rotates the belt 702, allowing items to move back and forth. This improves the efficiency of item storage and retrieval, reduces cold air loss, and facilitates use. After the items are placed... The door 9 is closed to the front side of the insulated box 1 using the hidden lock 13. The controller 601 in the blower mechanism 6 is opened, allowing the battery 602 to power the blower 603. The blower 603 blows the cold air from the lowest placement chamber 8 into the first installation chamber 3, and then flows into the corresponding placement chambers 8 on the upper two placement mechanisms 7 through the ventilation holes 604 on the partition 2, cooling and preserving the items. The gas in the upper two placement chambers 8 flows into the second installation chamber 5 through the ventilation holes 604 on the right partition 2. The activated carbon adsorption plate 605 in the second installation chamber 5 adsorbs the odor in the gas. The gas then flows into the lowest placement chamber 8 containing the cold source through the lowest ventilation hole 604 on the right partition 2, forming a cold air circulation. This ensures that the cold air is evenly distributed, prevents the items from freezing, and facilitates use.

[0038] In summary, this cold chain distribution preservation device uses the blower mechanism 6 to distribute cold air evenly, resulting in better preservation and preventing items from freezing. It also adds an odor absorption function, making it easier to store and retrieve items on the placement mechanism 7, improving work efficiency, reducing cold air loss, and facilitating use.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
