[0002] In scenarios such as cryogenic storage and transportation, medical emergency care, and outdoor camping, ice storage blankets are widely used as portable temperature control devices to provide localized cooling or maintain low-temperature environments. Traditional ice storage blankets typically employ a one-piece structure, with the cold storage medium encapsulated inside the blanket, requiring overall freezing or refrigeration during use. However, this integrated design presents several inconveniences during use, such as: fixed blanket dimensions, making it difficult to adapt to different application needs; the inability to replace the cold storage medium, resulting in limited cooling capacity; and inflexible overall storage and transportation, impacting the user experience. Furthermore, existing ice blankets generally lack targeted sealing and connection structures, making it easy for cold air to be lost when multiple blankets are spliced ​​together, thus reducing the insulation effect.

[0003] In summary, existing cold storage ice sheets have shortcomings in terms of structural flexibility, cold storage efficiency, and sealing connection, making it difficult to meet diverse application needs. Utility Model Content

[0031] The modular, detachable cold-storage ice blanket provided in this embodiment of the invention is designed to consist of at least two interlocking ice blanket units, making the overall structure modular, easy to disassemble and assemble. Each ice blanket unit has a top cover layer, a cold-storage functional layer, and a base layer from top to bottom, forming a complete functional module. Specifically, the recessed cold-storage chamber at the bottom of the top cover layer can effectively accommodate and fix the phase change cold storage body embedded therein.

[0045] Embodiments of this embodiment will now be described in more detail with reference to the accompanying drawings. While some embodiments of this embodiment are shown in the drawings, it should be understood that this embodiment can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this embodiment. It should be understood that the accompanying drawings and embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this embodiment.

[0046] In cold chain storage, transportation, and medical rescue scenarios, traditional ice-storage blankets have significant shortcomings due to their non-removable, monolithic structure: They are filled with cold-storage material and require complete freezing during use, making it impossible to adjust the size or replace the cold-storage unit as needed; furthermore, the lack of effective connecting structures between ice blankets leads to gaps during splicing, causing cold air loss and affecting the insulation effect. These design flaws—rigid structure, limited cold-storage capacity, and poor sealing—severely restrict the flexible application of ice blankets.

[0047] To address the aforementioned problems, this utility model provides a modular, detachable cold storage ice blanket. Figure 1 This is a schematic diagram of a modular, detachable cold storage ice blanket provided for an embodiment of the present utility model. Figure 2 This is a structural schematic diagram of an ice blanket unit provided in an embodiment of the present invention.

[0048] like Figure 1 and Figure 2 As shown, the modular detachable cold storage ice sheet includes at least two splicable ice sheet units 1, and each ice sheet unit 1 includes a top cover layer 2, a cold storage functional layer 3 and a base layer 4 stacked from top to bottom.

[0049] The top cover layer 2 has a recessed cold storage chamber at its bottom. The cold storage functional layer 3 includes a detachable phase change cold storage body, which is embedded in the cold storage chamber. The phase change cold storage body includes multiple layers of hydrogel plates. In this embodiment, the cold storage chamber at the bottom of the top cover layer 2 can be used to embed the detachable phase change cold storage body in the cold storage functional layer 3. The phase change cold storage body is composed of multiple layers of hydrogel plates, and the multi-layer structure design can enhance the cold storage effect and stability.

[0050] The periphery of the top cover layer 2 extends outward to form a reinforcing connecting frame 5. Two mounting through holes 6 are spaced apart along the length of the reinforcing connecting frame 5, and a multifunctional component is detachably installed within each of the two mounting through holes 6. In this embodiment, the reinforcing connecting frame 5, which extends outward from the periphery of the top cover layer 2, serves to enhance the overall structural strength of the ice blanket unit 1 and provide a stable foundation for the subsequent installation of the mounting through holes 6. The two mounting through holes 6, spaced apart along the length of the reinforcing connecting frame 5, allow for the detachable installation of the multifunctional component, improving the assembly flexibility and convenience of the ice blanket.

[0051] The multifunctional component includes a connecting component 7 for lateral connection of adjacent ice blanket units 1, and a locking component 8 for longitudinal locking of the top cover layer 2 and the base layer 4. Specifically, the multifunctional component in this embodiment includes the connecting component 7 and the locking component 8. The connecting component 7 is used for lateral connection of adjacent ice blanket units 1. Through a specific structural design, such as the snap-fit ​​of a snap-fit, it enables quick splicing and stable connection between ice blanket units 1, meeting the needs of ice blanket size and coverage area in different scenarios. The locking component 8 is used for longitudinal locking of the top cover layer 2 and the base layer 4. With the snap-fit ​​of a snap-fit, it ensures that each layer of the ice blanket fits tightly, preventing interlayer displacement or separation during use, and ensuring the integrity and sealing of the ice blanket.

[0052] The edge of the base layer 4 and the lower surface of the reinforcing connecting frame 5 form a sealed fit. This sealed fit can effectively prevent cold air leakage and improve the heat preservation performance of the ice blanket.

[0053] In practical applications, users can select an appropriate number of ice blanket units 1 to assemble and combine according to specific needs, such as the volume, shape, and usage scenario of the insulated items. Horizontal connections are achieved through connecting components 7, quickly constructing the required size of the cold storage ice blanket; vertical locking is achieved using locking components 8 to ensure the stability of the ice blanket structure. When cleaning or replacing the phase change cold storage element, the detachable design at the mounting through-holes 6 facilitates convenient and quick disassembly and maintenance, improving the lifespan and practicality of the ice blanket.

[0054] Figure 3 This is a schematic diagram of the structure of a top cover layer provided in an embodiment of the present utility model.

[0055] In an alternative embodiment, such as Figure 3 As shown, the top cover layer 2 is provided with a waterproof functional layer 9, a heat insulation functional layer 10 and a surface protective layer 11 sequentially composited from bottom to top; the periphery of the surface protective layer 11 extends outward to form a reinforced connecting frame 5.

[0056] In this embodiment, the waterproof functional layer 9 serves as the bottom layer of the top cover layer 2. Its main function is to prevent moisture penetration, protect the internal cold storage functional layer 3 and base layer 4 from moisture, and also help maintain the low-temperature environment inside the ice blanket. The heat insulation functional layer 10 is located above the waterproof functional layer 9. Its main function is to block external heat from being transferred to the interior, reduce the loss of cold energy, thereby improving the heat preservation effect of the ice blanket and extending the heat preservation time. The surface protective layer 11 is the outermost layer of the top cover layer 2. In addition to providing basic physical protection to prevent the ice blanket from being scratched or damaged during use, its special structural design, such as the reinforced connecting frame 5 extending outward from the periphery, enhances the overall structural stability of the ice blanket and provides a stable support platform for the installation of the through holes 6 and subsequent multifunctional components.

[0057] In actual manufacturing, the waterproof functional layer 9, the heat insulation functional layer 10, and the surface protective layer 11 can be tightly bonded together through processes such as bonding and hot pressing, ensuring no gaps between the layers and further improving the overall heat insulation and protective performance. For example, in medical cold chain transportation, this structural design can effectively prevent medicines or vaccines from being contaminated by the external environment and affected by temperature fluctuations, ensuring their quality stability during transportation; in the case of fresh food preservation, it can also effectively maintain the freshness and taste of food and reduce food spoilage caused by temperature changes.

[0058] Figure 4 This is a schematic diagram of the structure of a waterproof functional layer provided in an embodiment of the present utility model.

[0059] In an alternative embodiment, such as Figure 4 As shown, the waterproof functional layer 9 includes a polymer waterproof membrane 12, a non-woven fabric reinforcement layer 13, and a drainage layer 14, which are sequentially laminated from top to bottom.

[0060] The polymer waterproof membrane 12 serves as the surface layer of the waterproof functional layer 9 and adopts a sandwich composite structure. From top to bottom, it consists of an elastic deformation layer, a main barrier layer, and a surface wear-resistant layer. The thickness ratio of the elastic deformation layer to the surface wear-resistant layer is 1:1, and the thickness of the main barrier layer is equal to the sum of the thicknesses of the elastic deformation layer and the surface wear-resistant layer.

[0061] The sandwich composite structure of the polymer waterproof membrane 12 enables it to possess excellent waterproof performance while also exhibiting good flexibility and abrasion resistance. Specifically, the elastic deformation layer effectively absorbs and disperses external impacts, preventing damage to the waterproof membrane due to collisions or compression during use; the main barrier layer, as the core waterproof barrier, effectively blocks water penetration; and the surface abrasion-resistant layer enhances the surface abrasion resistance of the waterproof membrane, making it less prone to wear during frequent use and cleaning, thus extending its service life.

[0062] In practical applications, thermoplastic polyurethane (TPU) can be used as the elastic deformation layer. TPU has good elasticity, abrasion resistance and cold resistance, and can produce elastic deformation when subjected to external force, effectively absorbing and dispersing the force and preventing the waterproof membrane from breaking.

[0063] The primary barrier layer can be made of polyvinyl chloride (PVC) or polyvinylidene chloride (PVDC). PVC has excellent chemical stability and mechanical strength, effectively preventing water penetration; PVDC has even higher barrier properties and chemical resistance, further enhancing the waterproofing effect.

[0064] The surface abrasion-resistant layer can be made of polyethylene terephthalate (PET) or high-density polyethylene (HDPE). PET has good abrasion resistance, heat resistance, and dimensional stability, which can protect the surface of the waterproof membrane from abrasion; HDPE has high hardness and chemical stability, which can also effectively improve the surface abrasion resistance.

[0065] The non-woven fabric reinforcement layer 13 is located between the polymer waterproof membrane 12 and the drainage layer 14, serving as a connecting link. It not only further enhances the overall strength of the waterproof functional layer 9, preventing tearing and damage, but also provides additional protection for the polymer waterproof membrane 12, allowing it to better perform its waterproofing function. Simultaneously, the non-woven fabric reinforcement layer 13 has a certain degree of breathability, helping to regulate internal humidity and prevent moisture condensation between layers.

[0066] In practical applications, the nonwoven reinforcement layer 13 can be made of polypropylene (PP) or polyester (PET) nonwoven fabric. PP nonwoven fabric is lightweight, low-cost, and high-strength, providing basic support and protection for the waterproof functional layer 9; PET nonwoven fabric has higher strength and abrasion resistance, and can better withstand external forces, preventing the waterproof functional layer 9 from being torn or damaged.

[0067] The drainage layer 14, as the bottom layer of the waterproof functional layer 9, is in direct contact with the cold storage functional layer 3. Its lower surface is provided with radially distributed drainage channels that extend outwards from the center, ending at the edge of the reinforcing connecting frame 5 to form drainage outlets. This radial distribution of the drainage channels can quickly guide and drain any small amounts of water that may seep in, preventing moisture accumulation in the drainage layer 14 and ensuring that the cold storage functional layer 3 remains dry, maintaining its optimal cold storage performance. For example, when ice is used for cold chain transportation of pharmaceuticals, if there is a small amount of leakage from the pharmaceutical packaging, the drainage channels can promptly drain the liquid, avoiding any impact on the normal operation of the cold storage functional layer 3 and the safety of the pharmaceuticals.

[0068] In practical applications, the drainage layer 14 can be made of high-density polyethylene (HDPE) or polypropylene (PP). HDPE has good chemical stability and mechanical strength, and can withstand certain pressure and friction. At the same time, its smooth surface is conducive to the drainage and discharge of water. PP has the advantages of being lightweight, low cost, and corrosion resistant, and can also meet the basic requirements of the drainage layer 14.

[0069] In actual manufacturing, the polymer waterproof membrane 12, the non-woven fabric reinforcement layer 13, and the drainage layer 14 can be tightly bonded together through processes such as hot pressing and adhesive bonding to form an integral waterproof functional layer 9. For example, when manufacturing large-scale cold storage ice for fresh food logistics, the materials of each layer are cut according to the design dimensions, and then they are firmly bonded through a hot pressing process. Finally, radial drainage channels are processed in the drainage layer 14 to ensure that each part is structurally tight and functionally normal.

[0070] In practical applications, when ice is used for cold chain transportation or fresh food preservation, the waterproof functional layer 9 can effectively prevent external moisture intrusion and internal condensation seepage. For example, when transporting frozen food, the moisture formed by the melting of frost on the food surface will be quickly discharged through the drainage channel, while rainwater or humidity in the external environment will not penetrate into the ice layer and affect the frozen state of the food, thus ensuring the integrity of the cold chain.

[0071] Figure 5 This is a schematic diagram of the structure of a heat insulation functional layer provided in an embodiment of the present utility model.

[0072] In an alternative embodiment, such as Figure 5 As shown, the thermal insulation functional layer 10 has a gradient composite structure, including an aerogel felt layer 15, a ceramic fiber cotton layer 16, and a closed-cell foam layer 17.

[0073] The aerogel felt layer 15, serving as the surface layer of the thermal insulation functional layer 10, possesses extremely low thermal conductivity, effectively blocking heat conduction. Its surface is designed with a wavy, raised structure. This structure not only increases the surface area of ​​the insulation layer but also disrupts the direction of heat flow, further reducing heat transfer efficiency. For example, in cold chain transportation, when external hot air impacts the ice blanket, the wavy, raised structure complicates the flow of hot air, mitigating its impact on the internal cold environment.

[0074] In practical applications, the aerogel felt layer 15 can be composed of silica (SiO2) aerogel combined with other fibrous materials. For example, silica aerogel can be combined with glass fiber, polyimide fiber, etc., to form a felt-like material with high strength and flexibility. This material not only maintains the low thermal conductivity of aerogel, but also enhances its mechanical strength and durability, making it suitable for various complex operating environments.

[0075] The middle layer, ceramic fiber cotton 16, is soft and has excellent heat insulation properties. It incorporates an array of aluminum foil reflective films arranged at a 45-degree angle to form a heat-reflecting network. When heat is transferred via radiation, the aluminum foil reflective films reflect the heat back, reducing the amount of heat entering the ice blanket. For example, in direct sunlight outdoors, the aluminum foil reflective films can reflect solar radiation heat, preventing the internal temperature of the ice blanket from rising rapidly.

[0076] In practical applications, the ceramic fiber cotton layer 16 lies beneath the aerogel felt layer 15, primarily serving as a buffer and providing further insulation. Ceramic fiber cotton is typically made of ceramic fibers (such as silica-alumina fibers), possessing excellent high-temperature resistance and insulation properties. This material is soft and effectively absorbs and disperses pressure, preventing damage to the ice blanket when squeezed or impacted. Simultaneously, the aluminum foil reflective film array embedded within the ceramic fiber cotton reflects heat, enhancing the insulation effect.

[0077] The lower closed-cell foam layer 17 is composed of a large number of closed pores, which are filled with stagnant air. Since air itself is a poor conductor of heat, the closed-cell foam layer 17 can effectively prevent heat from entering the interior of the ice blanket through convection and conduction, thus playing a basic role in heat insulation.

[0078] In practical applications, the closed-cell foam layer 17, serving as the bottom layer of the thermal insulation layer 10, primarily prevents heat from entering the ice blanket through convection and conduction via its closed-cell structure. Closed-cell foam materials are typically polymer foam materials such as polyethylene (PE) or polypropylene (PP). These materials have numerous closed pores filled with stagnant air, effectively blocking heat transfer. The closed-cell foam layer 17 not only provides excellent thermal insulation but also offers some waterproofing and abrasion resistance, protecting the internal aerogel felt layer 15 and ceramic fiber cotton layer 16.

[0079] In the actual manufacturing process, these three layers of materials can be tightly bonded together using a special bonding process to form an integral heat insulation layer 10. For example, when producing cold storage ice blankets for vaccine transportation, the aerogel felt, ceramic fiber cotton, and closed-cell foam layer 17 are first cut into the required size and shape, and then high-temperature pressing technology is used to firmly bond them together, ensuring that there will be no separation between layers or material displacement during use.

[0080] In practical applications, the heat insulation layer 10 of this gradient composite structure can significantly improve the heat preservation effect of the ice blanket. Taking the transportation of fresh food as an example, during the transportation of seafood, ice cream and other foods with strict temperature requirements, the heat insulation layer 10 of the ice blanket can effectively maintain the internal low temperature environment and ensure that the quality of the food is not affected.

[0081] In an optional embodiment, the surface protective layer 11 may be a double-functionalized Oxford cloth layer, with a fluorinated abrasion-resistant coating on the outer surface and an antibacterial silver ion coating on the inner surface.

[0082] The fluorinated abrasion-resistant coating offers excellent wear and weather resistance, resisting friction and scratches during daily use and extending the lifespan of the ice blanket. The antibacterial silver ion coating effectively inhibits bacterial growth and reproduction, preventing bacteria from multiplying on the ice blanket's surface and maintaining its cleanliness and hygiene.

[0083] The outer surface of the Oxford cloth layer features micron-level water-guiding patterns, including parallel main channels and herringbone-shaped branch channels connecting them. The parallel main channels provide the primary guiding path for water flow, while the herringbone-shaped branch channels collect and guide water flowing from various directions, channeling it into the main channels. The main channels are distributed in an arc shape on the surface protective layer 11. This arc design helps to better adapt to the curved surface of the ice blanket, allowing water to flow smoothly along the arc path. Near the end of the main channels, close to the reinforcing connecting frame 5, is a flow-accelerating section. The depth of the flow-accelerating section is 20% to 30% greater than that of the main channels, while the width is narrowed by 15% to 20%. By increasing the depth and narrowing the width, the flow-accelerating section accelerates the water flow, rapidly expelling water from the ice blanket and preventing water accumulation on the surface.

[0084] In actual production, the Oxford cloth layer undergoes a special double-sided functionalization treatment to ensure that the fluorinated wear-resistant coating and the antibacterial silver ion coating adhere firmly to its surface. The micron-level water-guiding texture is formed on the outer surface of the Oxford cloth layer through precise mold pressing or laser engraving processes. For example, in the production of ice storage blankets for medical cold chain transportation, the Oxford cloth layer is first pretreated, then a fluorinated wear-resistant coating is laminated onto its outer surface using a coating process, and an antibacterial silver ion coating is applied to the inner surface. Next, micron-level water-guiding textures are engraved on the outer surface of the Oxford cloth layer using laser engraving equipment, ensuring the precision and quality of the water-guiding textures.

[0085] In practical applications, these designs of the surface protective layer 11 can effectively improve the practicality and hygiene of the ice blanket. Taking an outdoor picnic as an example, when the surface of the ice blanket is accidentally stained with dirt or water, the fluorinated abrasion-resistant coating can prevent scratches, the antibacterial silver ion coating can inhibit bacterial growth, and the micron-level water-guiding texture can quickly guide water out, keeping the surface of the ice blanket dry and clean.

[0086] Figure 6 This is a schematic diagram of a connecting component provided in an embodiment of the present utility model.

[0087] In an alternative embodiment, such as Figure 6 As shown, the connecting component 7 includes a first base 18 and a first locking fastener 19. The four corners of the bottom surface of the first base 18 are provided with first connecting posts 20 that are adapted to the mounting through holes 6. The ends of the first connecting posts 20 are provided with a locking structure that engages with the first locking fastener 19.

[0088] In this embodiment, the connecting component 7 includes a first base 18 and a first locking fastener 19. The four corners of the bottom surface of the first base 18 are provided with first connecting posts 20 adapted to the mounting through holes 6. These first connecting posts 20 can be precisely inserted into the mounting through holes 6 on the reinforced connecting frame 5, providing stable support points for subsequent locking. The ends of the first connecting posts 20 are provided with a locking structure that engages with the first locking fastener 19. This locking structure allows for quick connection and secure locking of adjacent ice blanket units 1 through simple operation. For example, in cold chain transportation transfer scenarios, when multiple ice blanket units 1 need to be quickly assembled to accommodate goods of different sizes, workers only need to align the first base 18 with the mounting through holes 6 and insert it, then engage it with the first locking fastener 19 to complete the connection operation, greatly improving work efficiency.

[0090] In an alternative embodiment, such as Figure 7 As shown, the locking assembly 8 includes a second base 21 and a second locking member 22. The bottom surface of the second base 21 is provided with second connecting posts 23 that are adapted to the mounting through holes 6. The end of the second connecting post 23 is provided with a locking structure that engages with the second locking member 22.

[0091] In this embodiment, the locking assembly 8 includes a second base 21 and a second locking fastener 22. The bottom surface of the second base 21 has second connecting posts 23 on both sides that are adapted to the mounting through holes 6, allowing for accurate insertion into the mounting through holes 6 and providing a stable connection base for longitudinal locking. The ends of the second connecting posts 23 are provided with a locking structure that engages with the second locking fastener 22. This engagement tightly locks the top cover layer 2 and the base layer 4 together, ensuring that the ice blanket does not shift or loosen during use. For example, when using the ice blanket outdoors, facing complex environments and frequent movement, the locking assembly 8 ensures the integrity and sealing of the ice blanket, preventing cold air leakage.

[0092] In actual manufacturing, the first base 18, the first fastener 19, the second base 21, and the second fastener 22 can be made of high-strength plastic or metal materials to ensure sufficient strength and durability. For example, when manufacturing refrigeration blankets for pharmaceutical transportation, medical-grade plastic materials are selected to make these components, which not only meet hygiene standards but also ensure that they will not be damaged during long-term transportation.

[0093] In practical applications, the combined use of connecting component 7 and locking component 8 gives the cold storage ice blanket a high degree of flexibility and practicality. Taking fresh food logistics and distribution as an example, delivery personnel can flexibly assemble the ice blanket unit 1 according to the space of the transport vehicle and the arrangement of the goods. The connecting component 7 is used to quickly complete the horizontal connection, and the locking component 8 is used to lock it vertically, ensuring the stability of the ice blanket during transportation and effectively maintaining the low-temperature environment required for fresh food.

[0094] Figure 8 This is a structural schematic diagram of a handle assembly provided in an embodiment of the present utility model.

[0095] In an alternative embodiment, such as Figure 8 As shown, the handle assembly includes a third base 24 and a third locking fastener 25. The bottom surface of the third base 24 is provided with third connecting posts 26 that are adapted to the mounting through holes 6. The end of the third connecting post 26 is provided with a locking structure that engages with the third locking fastener 25. A handle 27 is fixed on the top of the third base 24.

[0096] In this embodiment, the handle component can improve the portability of the ice blanket, making it convenient for users to carry and move it in different scenarios.

[0097] Specifically, the handle assembly includes a third base 24 and a third locking fastener 25. The bottom surface of the third base 24 has third connecting posts 26 on both sides that mate with the mounting through holes 6. These third connecting posts 26 can be precisely inserted into the mounting through holes 6 on the reinforced connecting frame 5, providing a stable connection base for the handle assembly. The ends of the third connecting posts 26 have a locking structure that engages with the third locking fastener 25. This engagement allows the handle assembly to be quickly and securely installed on the ice blanket unit 1. For example, during outdoor picnics or camping, when it is necessary to carry the ice blanket to the destination, the user simply aligns the third base 24 with the mounting through hole 6 and inserts it, then uses the third locking fastener 25 to secure it, easily installing the handle and allowing for easy carrying of the ice blanket.

[0098] A handle 27 is fixed above the third base 24. The handle 27 is typically made of soft and comfortable materials, such as rubber or high-grade plastic, and may also have a non-slip texture to enhance grip comfort and stability. The shape and size of the handle 27 are designed according to ergonomic principles, conforming to the gripping habits of most users and effectively reducing hand fatigue. For example, for large ice storage blankets used to transport large quantities of fresh food or medical supplies, the larger handle 27 design makes it easier for users to lift and carry them, even when wearing gloves.

[0099] In actual manufacturing, the third base 24 and the third locking fastener 25 can be made of high-strength, wear-resistant engineering plastics or metals to ensure sufficient strength and durability to withstand the weight of the ice pack and its contents. For example, when manufacturing ice packs for industrial cold chain transportation, metal is chosen for the handle assembly to meet the needs of frequent handling and long-term use.

[0100] In practical applications, the handle component greatly facilitates the use of the ice blanket. Taking daily household use as an example, when it is necessary to move the ice blanket from the refrigerator to the dining table, or when it needs to be moved to the washing area for cleaning, the handle component allows users to easily complete these operations without the need for additional tools or equipment, thus improving the efficiency of ice blanket use and the user experience.

[0101] In an optional embodiment, the reinforced connecting frame 5 and the base layer 4 are sealed together by a magnetic sealing assembly, which is provided with a first magnetic sealing strip and a second magnetic sealing strip.

[0102] The first magnetic sealing strip is embedded and fixed to the lower surface of the reinforcing connecting frame 5, while the second magnetic sealing strip is embedded and fixed to the upper surface of the edge of the base layer 4. The two form a magnetic sealing interface in the vertical direction, and the seal is achieved by magnetic attraction. For example, in cold chain transportation, after the ice blanket unit 1 is assembled, the base layer 4 and the reinforcing connecting frame 5 are simply attached, and the first and second magnetic sealing strips are immediately attracted to each other to form a seal.

[0103] In actual manufacturing, high-performance magnetic materials can be used to make the sealing strips to ensure stable and durable magnetism. During installation, the first magnetic sealing strip is precisely embedded into the groove reserved on the lower surface of the reinforcing connecting frame 5, and the second magnetic sealing strip is embedded into the groove on the upper surface of the edge of the base layer 4, and fixed by adhesive or hot pressing.

[0104] In practical applications, the advantages of magnetic sealing components are quite obvious. Taking the preservation of fresh food as an example, magnetic seals can respond quickly and fit tightly, effectively preventing cold air leakage and extending the food's shelf life. At the same time, this sealing method is easy to open and close. When it is necessary to clean the inside of the ice pack or replace the cold storage element, users can easily open the seal and quickly restore it after the operation is completed, ensuring that the ice pack's insulation performance is not affected.

[0105] Figure 9 This is a schematic diagram of the structure of a base layer provided in an embodiment of the present utility model.

[0106] In an alternative embodiment, such as Figure 9 As shown, the base layer 4 includes a waterproof and breathable membrane layer 28, a buffer support layer 29, and an anti-slip and wear-resistant layer 30, which are composited from top to bottom.

[0107] The waterproof and breathable membrane layer 28, serving as the surface layer of the base layer 4, primarily functions to prevent moisture from penetrating into the ice blanket while allowing internal moisture to escape, thus maintaining internal dryness. For example, during cold chain transportation, if the external environment has high humidity or a small amount of liquid spills, the waterproof and breathable membrane layer 28 can effectively block moisture from entering, protecting the internal cold storage layer 3 and the items from moisture. Meanwhile, moisture generated internally due to temperature changes can escape through the breathable membrane, preventing condensation inside.

[0108] In practical applications, the waterproof and breathable membrane layer 28 can be a polytetrafluoroethylene (PTFE) membrane, a polyurethane (PU) coated fabric, or an expanded polytetrafluoroethylene (ePTFE) film. Specifically, PTFE membranes possess excellent waterproof properties, effectively preventing moisture penetration while allowing water vapor to pass through, keeping the interior dry. For example, in extremely humid environments, such as cold chain transportation in tropical rainforests, PTFE membranes can prevent external moisture from entering the ice pack. PU coatings can be applied to various fabric substrates, such as nylon or polyester fabrics, to form a waterproof and breathable layer. This material combines the strength of fabric with the waterproof and breathable properties of PU, making it suitable for various cold chain scenarios. ePTFE films have a microporous structure, effectively blocking liquid water while allowing water vapor to pass through, maintaining the breathability of the internal environment. For example, in medical cold chain transportation requiring high breathability, ePTFE films can prevent bacterial and moisture intrusion while allowing internal moisture to escape.

[0109] The cushioning support layer 29, located between the waterproof and breathable membrane layer 28 and the anti-slip and wear-resistant layer 30, employs a honeycomb-shaped high-density polyethylene skeleton structure. This structure provides excellent cushioning performance, effectively absorbing and dispersing pressure to prevent damage to the internal items when the ice blanket is subjected to compression or impact. The honeycomb cells of the skeleton are filled with phase change gel, the phase change temperature of which can be set according to specific usage requirements; for example, the phase change temperature of the phase change gel can be -30℃ to 0℃. This gel can undergo a phase change within a specific temperature range, absorbing or releasing heat, thus playing an auxiliary role in cold storage. For example, when transporting fragile fresh food or medicine, the cushioning support layer 29 not only protects the items from physical damage but also provides additional assistance in maintaining a low-temperature environment through the cold storage properties of the phase change gel.

[0110] The anti-slip and wear-resistant layer 30, as the bottom layer of the base layer 4, is in direct contact with the surface where the ice blanket is placed. Its surface is provided with an array of anti-slip raised dots. These raised dots are arranged in an array, with a spacing of 2 to 3 millimeters between adjacent dots and a height difference of 0.5 to 1 millimeter. This effectively increases the friction between the ice blanket and the contact surface, preventing the ice blanket from sliding or shifting during use. For example, during vehicle transportation, even if the vehicle starts, brakes, or turns, the ice blanket can remain stably placed and will not affect the placement and transportation safety of goods due to slippage.

[0111] In practical applications, the anti-slip and wear-resistant layer 30 can be made of rubber, thermoplastic polyurethane (TPU) film, or polycarbonate (PC) alloy. Specifically, natural or synthetic rubber has good elasticity and a coefficient of friction, which can effectively increase the friction between the ice blanket and the contact surface, preventing slippage. For example, during vehicle transportation, the rubber anti-slip layer can prevent the ice blanket from slipping when the vehicle starts or brakes, ensuring the stability of the goods. TPU film has high strength and wear resistance, as well as good anti-slip properties, making it suitable for ice blankets that require frequent handling and use, such as in cold chain transportation in logistics centers. Polycarbonate (PC) alloy combines the strength and toughness of PC, with good wear resistance and anti-slip properties, making it suitable for high-intensity applications, such as industrial cold chain transportation.

[0112] In actual production, these three layers of materials are tightly bonded together using a special bonding process to form a single base layer 4. For example, when producing cold storage ice blankets for vaccine transportation, the waterproof and breathable membrane layer 28, the cushioning support layer 29, and the anti-slip and wear-resistant layer 30 are first cut to the required size and shape, and then high-temperature pressing technology is used to firmly bond them together, ensuring that there will be no separation between layers or material displacement during use.

[0113] In practical applications, the base layer 4 of this three-layer composite structure can significantly improve the practicality and reliability of the ice blanket. Taking outdoor activities as an example, when the ice blanket is placed on uneven ground or slopes, the anti-slip and wear-resistant layer 30 can prevent the ice blanket from sliding, the cushioning and support layer 29 protects the items inside the ice blanket from the impact of the ground, and the waterproof and breathable membrane layer 28 ensures that external moisture does not penetrate, maintains the internal low temperature environment, and ensures the quality and safety of the stored items.

[0114] Figure 10 This is a schematic diagram of another base layer structure provided in an embodiment of the present invention.

[0115] In an alternative embodiment, such as Figure 10 As shown, the base layer 4 includes a biocompatible layer 31, a temperature regulating layer 32, and an antibacterial substrate layer 33 arranged from top to bottom.

[0116] The biocompatible layer 31 is made of medical-grade silicone composite nonwoven fabric. This material has excellent biocompatibility and will not cause adverse reactions in the human body, making it suitable for medical applications. Its surface features a biomimetic microporous structure with pore sizes between 50 and 100 micrometers. These micropores are inspired by the pore structure of biological skin, ensuring both breathability and preventing the invasion of external microorganisms. For example, during the transportation of medical devices or pharmaceuticals, the biocompatible layer 31 can provide a relatively stable and safe environment, preventing the adhesion and growth of bacteria and other microorganisms.

[0117] In practical applications, the biocompatible layer 31 can be medical-grade silicone composite nonwoven fabric, polylactic acid (PLA) biocompatible membrane, or polyurethane (PU) biocompatible material, etc. Medical-grade silicone has excellent biocompatibility and will not cause allergic or toxic reactions. When composited with nonwoven fabric, it combines flexibility and strength, with a biomimetic microporous structure on its surface. The pore size is between 50 and 100 micrometers, ensuring both breathability and preventing the invasion of external microorganisms. For example, during the transportation of medical devices or pharmaceuticals, the biocompatible layer 31 can provide a relatively stable and safe environment for these items, preventing the adhesion and growth of bacteria and other microorganisms. PLA is a biodegradable polymer with excellent biocompatibility and can be used to prepare the biocompatible layer 31. It can be made into a film through processes such as extrusion or casting, and the surface can be microporously processed to enhance breathability and prevent microbial invasion. PU material has good biocompatibility and mechanical properties, and its biocompatibility can be further improved by adding biocompatible fillers or surface modification, making it suitable for biocompatible layers 31 that require high strength and flexibility.

[0118] The main function of the temperature regulating layer 32 is to regulate the temperature according to changes in the ambient temperature in order to maintain the relative stability of the internal environment of the ice blanket. It buffers the impact of ambient temperature fluctuations on the interior of the ice blanket by absorbing and releasing heat. For example, when the ambient temperature suddenly rises, the temperature regulating layer 32 can absorb some heat and slow down the rate at which the internal temperature of the ice blanket rises; conversely, when the ambient temperature drops, it can release the stored heat to prevent the internal temperature of the ice blanket from dropping too quickly.

[0119] In practical applications, the temperature regulating layer 32 can be a phase change material (PCM), metal foam, or polymer gel material. Among these, PCMs can absorb, store, and release heat within a specific temperature range, thus achieving temperature regulation. Commonly used PCMs include paraffin wax, fatty acids, and hydrates. For example, encapsulating paraffin-based PCMs in a polymer carrier to form phase change microcapsules, and then dispersing them in a polymer matrix, can prepare a composite material with temperature regulating function, used for the temperature regulating layer 32 of an ice blanket. Metal foams have high thermal conductivity and specific heat capacity, enabling them to quickly absorb and release heat, thus playing a role in temperature regulation. For example, aluminum foam can be used in the temperature regulating layer 32; its porous structure increases the heat exchange area with the surrounding environment, achieving a better temperature buffering effect. Some polymer gel materials are temperature-responsive, capable of absorbing or releasing moisture when the temperature changes, thereby achieving temperature regulation. For example, poly(N-isopropylacrylamide) (PNIPAM) and its copolymer gels can undergo a phase change when the temperature approaches their lower critical solution temperature (LCST), absorbing or releasing a large amount of heat, making them suitable for the preparation of the temperature regulating layer 32.

[0120] The antibacterial substrate layer 33 is made of silver-plated nylon mesh. Silver ions have broad-spectrum antibacterial properties and can effectively inhibit bacterial growth. This mesh has a mesh density of 20 to 30 meshes, and its large specific surface area allows the silver ions to exert their antibacterial effect more fully. The silver ion loading is greater than 200 micrograms per square centimeter, ensuring the long-lasting antibacterial effect. For example, during the cold chain transportation of food or pharmaceuticals, the antibacterial substrate layer 33 can prevent bacteria from growing on the surface of ice, reducing the risk of bacterial contamination and ensuring the safety of stored items.

[0121] In actual production, these three layers of materials are tightly bonded together through a special process. For example, when producing cold storage ice blankets for medical cold chain transportation, the medical silicone composite non-woven fabric, temperature regulating material, and silver-plated nylon mesh fabric are first cut to the required size, and then bonded together into a whole base layer 4 by hot pressing or adhesive bonding, ensuring that the layers are firmly bonded and that there is no delamination or separation.

[0122] In practical applications, the base layer 4 of this structure has significant advantages in the fields of medical and food cold chain transportation. Taking vaccine transportation as an example, the biocompatible layer 31 provides a safe and pollution-free environment for the vaccine, the temperature regulating layer 32 helps maintain the stable low temperature conditions required for the vaccine, and the antibacterial substrate layer 33 prevents bacterial growth from affecting vaccine quality. The three work together to ensure the safety and efficacy of the vaccine during transportation.

[0123] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the present utility model embodiments.

[0124] Preparation: Select the appropriate size and quantity of ice blanket units 1 according to usage requirements, and check that all components are intact, including the top cover layer 2, cold storage layer 3, base layer 4, reinforced connecting frame 5, mounting through hole 6, phase change cold storage element, waterproof layer 9, heat insulation layer 10, surface protective layer 11, connecting components 7, locking components 8, handle components, magnetic sealing components, etc. Ensure that all components are complete and undamaged.

[0125] Assembling Ice Blanket Unit 1: Place two ice blanket units 1 side by side, aligning their reinforcing connecting edges 5. Align the first base 18 of the connecting component 7 with the mounting through hole 6 on the reinforcing connecting edge 5 of one of the ice blanket units 1, and insert the first connecting posts 20 at the four corners of the bottom surface of the first base 18 into the mounting through hole 6. Fit the reinforcing connecting edge 5 of the other ice blanket unit 1 with the reinforcing connecting edge 5 of the ice blanket unit 1 with the connecting component 7 installed, placing the connecting component 7 between them, thus achieving a lateral connection between the two ice blanket units 1. At the end of the first connecting post 20, install the first locking fastener 19 using a snap-fit ​​mechanism to fix the connecting component 7 onto the ice blanket unit 1. Using the same method, more ice blanket units 1 can be assembled to form the desired ice blanket size and shape.

[0126] Install the phase change cold storage element: Embed the phase change cold storage element into the cold storage chamber at the bottom of the top cover layer 2. The phase change cold storage element is composed of multiple layers of hydrogel panels, which have good cold storage performance and reusability. During installation, align the phase change cold storage element with the opening of the cold storage chamber and gently place it into the chamber, ensuring that it fits tightly against the inner wall of the cold storage chamber to fully exert its cold storage effect.

[0127] Install the locking assembly 8: Align the second base 21 of the locking assembly 8 with the mounting through hole 6 on the reinforcing connecting frame 5 of the ice blanket unit 1, and insert the second connecting posts 23 on both sides of the bottom surface of the second base 21 into the mounting through hole 6. At the end of the second connecting post 23, install the second locking fastener 22 by snap-fit, thus fixing the locking assembly 8 onto the ice blanket unit 1. The locking assembly 8 is used for longitudinal locking of the top cover layer 2 and the base layer 4, ensuring that the layers of the ice blanket fit tightly together during use, and preventing interlayer displacement or detachment.

[0128] Install the handle assembly: Align the third base 24 of the handle assembly with the mounting through hole 6 on the reinforcing connecting frame 5 of the ice blanket unit 1, and insert the third connecting posts 26 on both sides of the bottom surface of the third base 24 into the mounting through hole 6. Install the third locking fastener 25 at the end of the third connecting post 26 through a snap-fit ​​mechanism to fix the handle assembly to the ice blanket unit 1. The handle 27 of the handle assembly is located above the third base 24 for easy lifting of the ice blanket by the user.

[0129] Inspect the magnetic sealing assembly: Ensure that the reinforcing connecting frame 5 and the base layer 4 are sealed together by the magnetic sealing assembly. A first magnetic sealing strip is embedded and fixed to the lower surface of the reinforcing connecting frame 5, and a second magnetic sealing strip is embedded and fixed to the upper surface of the edge of the base layer 4. When the base layer 4 is in contact with the reinforcing connecting frame 5, the first and second magnetic sealing strips form a magnetic sealing interface in the vertical direction, achieving a seal through magnetic attraction.

[0130] Using the ice blanket: Cover the assembled ice-storage blanket over items that need insulation, such as medicines, vaccines, and fresh food. Ensure the ice blanket completely covers the item to maintain the low-temperature environment to the maximum extent. During use, the phase-change cold storage element releases cold energy to maintain the low temperature inside the ice blanket. The waterproof and breathable membrane layer 28 prevents external moisture from intruding, the cushioning support layer 29 protects the internal items from compression and impact, and the anti-slip and wear-resistant layer 30 ensures the ice blanket is stable and does not slip on the placement surface.

[0131] Maintenance and Cleaning: After use, allow the ice blanket to thaw naturally in a suitable environment for future use. After thawing, clean each layer of the ice blanket. When cleaning, take care not to damage the structure and function of each layer, especially the waterproof and breathable membrane layer 28, the cushioning support layer 29, and the anti-slip and wear-resistant layer 30. Removable parts, such as the phase change cold storage element, connecting components 7, locking components 8, and handle components, can be cleaned and maintained individually to ensure their performance is not affected.
