Abstract
Description
Technical Field
[0001] This utility model relates to the field of preservation ice pack technology, specifically to preservation ice packs for cold chain transportation of fresh vegetables. Background Technology
[0002] In the cold chain transportation of fresh vegetables, preservation ice packs are a key auxiliary material for maintaining a low-temperature environment. Their working principle involves the phase change of the refrigerant inside the ice pack, which absorbs heat and continuously releases cold energy during transportation, stabilizing the temperature inside the vehicle within the suitable range for vegetable preservation. Currently, mainstream ice packs on the market use high-molecular polymers as the outer shell and are filled with environmentally friendly refrigerants such as sodium carboxymethyl cellulose and glycerin. They have a phase change temperature range of -5℃ to 5℃ and a cold-keeping time of 48-72 hours. However, some existing ice packs use heat-sealing, making it difficult to refill with refrigerant later, causing inconvenience. Therefore, the sealing method for ice packs that need to be used repeatedly for a long time needs to be upgraded.
[0003] For example, the patent with authorization announcement number CN213567594U discloses a cold chain transportation preservation ice pack with double-layer ice packs to prevent the ice pack containing cold storage agent from being exposed, thereby reducing damage and extending service life. In addition, the flexible sealing method makes it convenient for users to add cold storage agent later. However, there are still areas for improvement.
[0004] Most ice packs are placed together with goods, with filling components such as the refrigerant chuck exposed. During the handling or transportation of goods, the goods or workers may squeeze, step on, or impact the filling components. Moreover, these ice packs are not disposable and have a long service life. After repeated squeezing, the filling components may be deformed or damaged, causing them to rotate unevenly or even leak refrigerant. Utility Model Content
[0005] To address the aforementioned issues, this application provides a cold chain transport ice pack for fresh vegetables, resolving the problem of leakage of filling components such as the dispensing block, which could be damaged by external forces.
[0006] A cold chain transport ice pack for fresh vegetables includes a shell, a liquid storage bag for holding a cold storage agent is fixedly installed inside the shell, and a filling tube for adding cold storage agent to the liquid storage bag is fixedly installed at the top of the liquid storage bag. The shell is made of rigid material.
[0007] A sinking trough is located at the top of the shell, and the filling pipe is installed inside the sinking trough.
[0008] A transparent cover is bolted to the top of the sinkhole.
[0009] Preferably, a plurality of magnets are embedded and fixedly installed on the top of the housing.
[0010] Preferably, the inner side of the filling tube is threaded with a threaded plug, and the threaded plug has multiple filling holes through the middle.
[0011] Preferably, a linkage column is fixedly installed on the top of the threaded plug, and a rotating disk is fixedly installed on the top of the linkage column, with the outer side of the rotating disk being frosted.
[0012] Preferably, a rubber plug is fixedly installed on the outside of the linkage column, the rubber plug being thicker at the top and thinner at the bottom.
[0013] Preferably, multiple heat exchange plates are embedded and fixedly installed on the outer side of the shell, and multiple through holes are opened through the middle of the heat exchange plates.
[0014] Preferably, a plurality of Velcro straps are embedded and fixedly installed on the outer side of the housing. The Velcro straps are installed around the heat exchange plate, and an insulation blanket is attached to the outer side of the Velcro straps.
[0015] The beneficial effects of this utility model are as follows:
[0016] The fresh vegetable cold chain transportation preservation ice pack of this utility model has an injection tube installed inside the sinking trough, which can effectively avoid damage to the injection tube by external force. Moreover, the transparent cover is fixedly installed on the top of the sinking trough, which makes the injection tube more intact and conducive to long-term use.
[0017] Workers can use magnets to place ice packs on the top of the truck bed, which is more stable and saves loading space in the lower part of the truck bed.
[0018] Multiple Velcro straps are embedded and fixed on the outside of the shell. The Velcro straps are installed around the heat exchange plate, and an insulation blanket is attached to the outside of the Velcro straps to isolate the outside hot air. The insulation blanket can be removed from the required cooling position as needed. The cooling effect can also be controlled by the number of open sections of the heat exchange plate. Alternatively, during the transportation of ice packs, all insulation blankets can be covered on the outside of the heat exchange plate to reduce the consumption of cold air during transportation.

[0026] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.
[0027] like Figure 1-4 As shown, this utility model embodiment provides a fresh vegetable cold chain transportation preservation ice pack, including a shell 1, a liquid storage bag 12 for storing cold storage agent is fixedly installed on the inner side of the shell 1, and a filling tube 13 for adding cold storage agent to the liquid storage bag 12 is fixedly installed on the top of the liquid storage bag 12. The shell 1 is made of rigid material.
[0028] The sinking trough 14 is opened at the top of the shell 1, and the filling pipe 13 is installed inside the sinking trough 14, which can effectively avoid damage to the filling pipe 13 by external force.
[0029] The transparent cover 6 is fixed to the top of the sink trough 14 by bolts, which makes the filling pipe 13 more intact and conducive to long-term use.
[0030] Specifically, multiple magnets 5 are embedded and fixedly installed on the top of the shell 1. Workers can use the magnets 5 to place ice packs on the top of the carriage, which is relatively stable and saves loading space in the lower part of the carriage.
[0031] Specifically, the inner side of the filling tube 13 is threaded with a threaded plug 10, and the threaded plug 10 has multiple filling holes 11 through the middle, through which the refrigerant flows from the filling holes 11 to the liquid storage bag 12.
[0032] Specifically, a linkage column 8 is fixedly installed on the top of the threaded plug 10, and a rotating disk 7 is fixedly installed on the top of the linkage column 8. The outer side of the rotating disk 7 is frosted to increase the coefficient of friction and facilitate the rotation of the rotating disk 7 by the operator.
[0033] Specifically, a rubber plug 9 is fixedly installed on the outside of the linkage column 8 to seal the filling tube 13. The rubber plug 9 is thicker at the top and thinner at the bottom, making it easy to insert into the filling tube 13 and providing a better sealing effect.
[0034] In this embodiment, when adding the refrigerant, the operator removes the transparent cover 6, rotates the rotating disk 7, and moves the rubber stopper 9 and the threaded stopper 10 upward. The rubber stopper 9 is completely separated from the filling tube 13. The operator adds the refrigerant to the storage bag 12 through the filling hole 11. After the filling is completed, the rotating disk 7 is rotated in the opposite direction so that the rubber stopper 9 seals the filling tube 13. Finally, the transparent cover 6 is fixed with bolts.
[0035] Specifically, multiple heat exchange plates 2 are fixedly installed on the outer side of the shell 1. Multiple through holes are opened in the middle of the heat exchange plates 2, through which hot air enters and exchanges heat with the cold storage agent, thereby achieving cooling.
[0036] Specifically, multiple Velcro straps 3 are embedded and fixedly installed on the outer side of the shell 1. The Velcro straps 3 are installed around the heat exchange plate 2. An insulation blanket 4 is attached to the outer side of the Velcro straps 3 to isolate the outside hot air. The insulation blanket 4 can be removed from the required cooling position as needed. The cooling effect can also be controlled by the number of open sections of the heat exchange plate 2. Alternatively, during the transportation of ice packs, all insulation blankets 4 can be covered on the outside of the heat exchange plate 2 to reduce the consumption of cold air during transportation.
[0037] 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 scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
