Abstract
Description
Technical Field
[0001] This utility model relates to the field of human body cooling technology, and in particular to a cold compress component and a cooling garment using the same. Background Technology
[0002] Based on the relationship between ambient temperature and human body thermal balance, living environments above 35℃ and production environments above 32℃ are generally considered high-temperature environments. In high-temperature environments, human physiological functions, especially thermoregulation, water and salt metabolism, and blood circulation, undergo abnormal changes, endangering the personal safety of workers and causing unnecessary economic losses.
[0003] For people working continuously in outdoor environments without air conditioning, especially in high-temperature conditions, such as construction workers under the scorching sun or maintenance personnel performing high-altitude maintenance, they often have to overcome various discomforts caused by the high temperatures to work for extended periods. When working in high-temperature conditions wearing ordinary clothing, people sweat. The sweat diffuses and migrates to the surface of the clothing, and some heat is carried away through evaporation. However, the evaporation source provided by sweat is limited, so the amount of heat carried away is also limited. Especially when working continuously in high-temperature environments for a period of time, ordinary clothing cannot achieve a cooling effect within a certain timeframe.
[0004] To address the aforementioned issues, existing technologies have developed cooling and air-conditioning garments for regulating body temperature. For example, Chinese utility model patent CN220343733U, entitled "A Phase Change Cooling Garment with Excellent Cooling Effect," uses a water pump to pump ice water into a liquid circulation pipeline before it enters an ice water bag. This allows the ice water to absorb body heat during circulation, achieving a cooling effect. However, this structural solution lacks consideration for liquid medium loss. Since the liquid medium may undergo micro-permeation or micro-evaporation through the pipeline, the volume of the circulating liquid medium within the refrigeration unit decreases, causing poor circulation and affecting cold air transfer. Furthermore, the liquid medium may also experience cold air loss during its flow into and out of the ice water bag, which is detrimental to improving the refrigeration efficiency of the refrigeration equipment.
[0005] To further reduce heat loss of liquid media during entry and exit from the cold compress bag via pipes, existing technologies have developed a direct cooling technology that transfers cold energy directly to the cold storage material inside the cold compress bag via a cooling block. For example, Chinese invention patent CN119289548A, "A Semiconductor Cooling Mechanism," illustrates this. However, direct cold energy transfer is typically achieved through a metal cooling block, which, after processing, inevitably retains some burrs (i.e., flash, etc.) on its surface. These burrs can easily puncture or crush the flexible cold compress bag during subsequent processing, leading to leakage of the cold storage material inside the bag and severely impacting product yield and reliability. Utility Model Content
[0006] The purpose of this invention is to propose a cold compress component that, while ensuring effective transfer of cold energy, greatly reduces the risk of breakage of the cold compress bag, thereby improving product yield and reliability and overcoming the shortcomings of the prior art.
[0007] Another objective of this invention is to provide a cooling garment using the aforementioned cold compress component, which is beneficial for improving the local cooling effect of the cooling garment.
[0008] To achieve this objective, the present invention adopts the following technical solution: A cold compress assembly includes a cooling block, a plastic covering ring, and a cold compress bag; The cooling block includes a cooling conducting part and a cooling transferring part, with the cooling conducting part disposed on the outside of the cold compress bag and the cooling transferring part disposed on the inside of the cold compress bag; the cold compress bag is used to contain cold storage material, the cooling conducting part is used to be in contact with the cooling end of the refrigerator, and the refrigerator transfers cold energy to the cold storage material through the cooling block; The plastic covering ring wraps around the top, side walls, and bottom edge of the cooling section, and the bottom surface of the cooling section is exposed at the bottom of the plastic covering ring; the plastic covering ring is disposed inside the cold compress bag, and the opening of the cold compress bag is in contact with the surface of the plastic covering ring.
[0009] Preferably, the cross-sectional area of the cooling transfer section is greater than or equal to the cross-sectional area of the cooling conduction section, and the plastic covering ring completely covers the top surface of the cooling transfer section.
[0010] Preferably, the top surface has inwardly recessed upper anti-scratch grooves on both sides, and the upper anti-scratch grooves are located between the cooling guide part and the cooling transfer part, and the groove walls of the upper anti-scratch grooves have smooth surfaces. The inner top wall of the plastic-coated ring is provided with a first protrusion that matches the shape of the upper anti-scratch groove, and the first protrusion is accommodated in the upper anti-scratch groove.
[0011] Preferably, the bottom sides of the cooling section are recessed inward and provided with lower anti-scratch grooves, and the lower anti-scratch grooves are located at the edge of the bottom surface, and the groove walls of the lower anti-scratch grooves are smooth surfaces; The inner bottom wall of the plastic-coated ring is provided with a second protrusion that matches the shape of the lower anti-scratch groove, and the second protrusion is accommodated in the lower anti-scratch groove.
[0012] Preferably, the top surface has inwardly recessed anti-detachment grooves on both sides, and the anti-detachment grooves are located outside the upper anti-scratch groove; the anti-detachment groove includes a connecting part and a protruding part connected from top to bottom, and the width of the protruding part is greater than the width of the connecting part; The inner top wall of the plastic-coated ring is also provided with a third protruding rib that matches the shape of the anti-detachment groove, and the third protruding rib is accommodated in the anti-detachment groove.
[0013] Preferably, both the anti-detachment groove and the third protrusion are inverted T-shapes.
[0014] Preferably, the upper anti-scratch groove extends along the length of the cooling section and penetrates the cooling section; The lower anti-scratch groove extends along the length of the cooling section and penetrates the cooling section. The anti-detachment groove extends along the length of the cooling section and penetrates the cooling section.
[0015] Preferably, the bottom surface is flush with the lower surface of the plastic-coated ring.
[0016] Preferably, the cold compress bag includes an inner bag and an outer bag that are sequentially arranged from the inside out, and the inner bag and the outer bag together form a cavity for accommodating the cold storage material.
[0017] A cooling garment includes a semiconductor cooling chip and the aforementioned cooling patch assembly, wherein the cold end face of the semiconductor cooling chip is in contact with the cooling block.
[0018] The technical solution provided by this utility model can include the following beneficial effects: 1. This solution utilizes plastic wrapping rings to wrap the top, side walls, and bottom edges of the cooling transfer section in the cooling block. This allows the cooling transfer section to be isolated from the cold compress bag through the plastic wrapping rings, avoiding direct contact between the cooling transfer section and the cold compress bag. This prevents the burrs of the cooling block from puncturing or crushing the flexible cold compress bag during subsequent processing, which could lead to leakage of the cold storage material inside the bag.
[0019] 2. Since the thermal conductivity of the plastic-coated ring is generally lower than that of the heat-conducting block used to transfer cold, this characteristic is beneficial for altering the heat flow distribution of the heat-conducting block. Compared to the large-area exposure of the heat transfer section in existing technologies to achieve cold transfer, the plastic-coated ring in this solution effectively reduces the heat conduction area between the heat-conducting block and the cold storage material. This causes the transferred cold energy to be mainly concentrated on the exposed bottom surface of the plastic-coated ring, which helps to create a larger temperature gradient between the cold storage material and human skin, thereby increasing the local cooling intensity. Thanks to the optimized heat conduction mechanism resulting from the structural improvements in this solution, the cooling effect of the cooling patch component is further improved, better meeting the user's cooling needs.

Detailed Implementation
[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0030] This technical solution provides a cold compress assembly, characterized in that it includes a cooling block 1, a plastic covering ring 2, and a cold compress bag 3; The cooling block 1 includes a cooling conducting part 11 and a cooling transfer part 12, with the cooling conducting part 11 disposed on the outside of the cold compress bag 3 and the cooling transfer part 12 disposed inside the cold compress bag 3; the cold compress bag 3 is used to contain cold storage material, the cooling conducting part 11 is used to be in contact with the cooling end of the refrigerator, and the refrigerator transfers cold energy to the cold storage material through the cooling block 1; The plastic covering ring 2 wraps around the top, side wall and bottom edge of the cooling part 12, and the bottom surface 121 of the cooling part 12 is exposed at the bottom of the plastic covering ring 2; the plastic covering ring 2 is disposed inside the cold compress bag 3, and the opening of the cold compress bag 3 is in contact with the surface of the plastic covering ring 2.
[0031] To reduce the risk of breakage of the cold compress bag 3 and improve product yield and reliability, this technical solution proposes a cold compress component, such as... Figure 1-8 As shown, the device includes a cooling block 1, a plastic covering ring 2, and a cold compress bag 3. The cooling section 11 is designed to be in contact with the cooling end of the refrigerator, and the bottom surface 121 of the cooling transfer section 12 is exposed at the bottom of the plastic covering ring 2. This allows the cooling energy generated by the refrigerator to pass sequentially through the cooling section 11 and the cooling transfer section 12, and then through the bottom surface 121 of the cooling transfer section 12 to the cold storage material (such as water, gel, or other materials capable of storing and releasing cold energy) inside the cold compress bag 3. Specifically, this design utilizes the plastic covering ring 2 to wrap around the top, side walls, and bottom edge of the cooling transfer section 12 in the cooling block 1. This allows the cooling transfer section 12 to be isolated from the cold compress bag 3 through the plastic covering ring 2, preventing direct contact between the cooling transfer section 12 and the cold compress bag 3. This also prevents the burrs of the cooling block 1 from puncturing or crushing the flexible cold compress bag 3 during subsequent processing, which could lead to leakage of the cold storage material inside the bag.
[0032] Furthermore, since the thermal conductivity of the plastic-coated ring 2 is generally lower than that of the cooling block 1 used to transfer cold energy, this characteristic is beneficial for altering the heat flow distribution of the cooling block 1. Compared to the large-area exposure of the cold transfer section in Chinese invention patent CN119289548A to achieve cold energy transfer, the plastic-coated ring 2 in this solution effectively reduces the effective heat conduction area between the cooling block 1 and the cold storage material. This results in the transferred cold energy being mainly concentrated on the bottom surface 121 exposed on the plastic-coated ring 2, which helps to create a larger temperature gradient between the cold storage material and human skin, thereby increasing the local cooling intensity. Thanks to the optimized heat conduction mechanism brought about by the structural improvements in this solution, the cooling effect of the cold compress component is further improved, better meeting the user's cooling needs.
[0033] It should be noted that the cooling block 1 in this solution can preferably be an aluminum block, and the plastic covering ring 2 can preferably be made of synthetic polymer materials such as polyvinyl chloride (PVC) or polyamide (PA, i.e., nylon), and is cast into the outer edge of the cooling section 12 by injection molding. Furthermore, the adhesion between the opening of the cold compress bag 3 and the surface of the plastic covering ring 2 can be achieved by adhesive bonding or by melt pressing.
[0034] Preferably, the cooler in this solution can be a semiconductor refrigeration chip. Specifically, the semiconductor refrigeration chip is made using the Peltier effect, which refers to the phenomenon that when a direct current passes through a thermocouple composed of two semiconductor materials, one end of the thermocouple absorbs heat and the other end releases heat; in other words, the semiconductor refrigeration chip is made of two semiconductor materials, forming a hot end and a cold end. The cold end continuously absorbs heat to achieve cooling, while the hot end continuously releases heat to achieve heat dissipation.
[0035] To further explain, the cross-sectional area of the cooling transfer section 12 is greater than or equal to the cross-sectional area of the cooling conduction section 11, and the plastic covering ring 2 completely covers the top surface 122 of the cooling transfer section 12.
[0036] In this way, on the one hand, the volume of the cooling part 11 can be reduced, and on the other hand, the heat conduction area of the cooling part 12 (i.e., the area of the bottom surface 121) can be increased, thereby improving the cooling effect of the cooling bag 3.
[0037] To further explain, the top surface 122 has inwardly recessed upper anti-scratch grooves 1221 on both sides, and the upper anti-scratch grooves 1221 are located between the cooling part 11 and the cooling transfer part 12, and the groove wall of the upper anti-scratch groove 1221 is a smooth surface. The inner top wall of the plastic covering ring 2 is provided with a first protrusion 21 that matches the shape of the upper anti-scratch groove 1221, and the first protrusion 21 is accommodated in the upper anti-scratch groove 1221.
[0038] To further reduce the risk of damage to the cold compress bag 3, this solution also includes a smooth upper anti-scratch groove 1221 between the cooling conduction section 11 and the cooling transfer section 12, thus ensuring a continuous and smooth connection surface between the cooling conduction section 11 and the cooling transfer section 12. Additionally, a first protrusion 21 is added to the inner top wall of the plastic covering ring 2 to fill the interior of the upper anti-scratch groove 1221, making it less likely for the plastic covering ring 2 to detach from the cooling conduction block 1.
[0039] To further explain, the bottom sides of the cooling section 12 are recessed with lower anti-scratch grooves 1211, and the lower anti-scratch grooves 1211 are located at the edge of the bottom surface 121. The groove wall of the lower anti-scratch grooves 1211 is a smooth surface. The inner bottom wall of the plastic-coated ring 2 is provided with a second protrusion 22 that matches the shape of the lower anti-scratch groove 1211, and the second protrusion 22 is accommodated in the lower anti-scratch groove 1211.
[0040] To further reduce the risk of damage to the cooling bag 3, this solution also includes a smooth-walled lower anti-scratch groove 1211 at the bottom edge of the cooling transfer section 12, resulting in a continuous and smooth bottom edge of the cooling transfer section 12. Similarly, a second protrusion 22 is added to the inner bottom wall of the plastic covering ring 2 to fill the interior of the lower anti-scratch groove 1211, making it less likely for the plastic covering ring 2 to detach from the cooling block 1.
[0041] To further explain, the top surface 122 has inwardly recessed anti-detachment grooves 1222 on both sides, and the anti-detachment grooves 1222 are located outside the upper anti-scratch groove 1221; the anti-detachment grooves 1222 include a connecting portion 1222a and a protrusion 1222b connected sequentially from top to bottom, and the width of the protrusion 1222b is greater than the width of the connecting portion 1222a; The inner top wall of the plastic-coated ring 2 is also provided with a third protruding rib 23 that matches the shape of the anti-detachment groove 1222, and the third protruding rib 23 is accommodated in the anti-detachment groove 1222.
[0042] In a more preferred embodiment of this technical solution, in order to improve the bonding between the plastic covering ring 2 and the cooling transfer part 12, the solution also provides anti-detachment grooves 1222 on both sides of the top surface 122, and optimizes the width of the connecting part 1222a and the width of the protrusion 1222b in the anti-detachment groove 1222, which is more conducive to preventing the plastic covering ring 2 from separating from the cooling transfer part 12.
[0043] To further explain, the anti-detachment groove 1222 and the third protrusion 23 are both inverted T-shaped.
[0044] To further explain, the upper anti-scratch groove 1221 extends along the length direction of the cooling section 12 and penetrates the cooling section 12; The lower anti-scratch groove 1211 extends along the length of the cooling section 12 and penetrates the cooling section 12; The anti-detachment groove 1222 extends along the length of the cooling section 12 and penetrates the cooling section 12.
[0045] This is more conducive to improving the bonding between the plastic-coated ring 2 and the cooling section 12.
[0046] To further explain, the bottom surface 121 is flush with the lower surface of the plastic covering ring 2.
[0047] This makes it easier to transfer cold energy to the cold storage material inside the cold compress bag 3 through the bottom surface 121 of the cold transfer section 12.
[0048] To further explain, the cold compress bag 3 includes an inner bag 31 and an outer bag 32 that are sequentially arranged from the inside out. The inner bag 31 and the outer bag 32 together form a receiving cavity 301 for accommodating the cold storage material.
[0049] In another preferred embodiment of this technical solution, the cold compress bag 3 is designed as a "double-bag nested" structure, which completely avoids direct contact between the cooling block 1 and the outer bag 32, and can more effectively prevent the leakage of the cold storage material in the receiving cavity 301, thereby improving the product yield and reliability.
[0050] Preferably, the inner bag 31 has a thickness of 0.3 mm, which can ensure the effective transfer of cold energy while preventing leakage.
[0051] A cooling garment includes a semiconductor cooling chip and the aforementioned cooling patch assembly, wherein the cold end face of the semiconductor cooling chip is in contact with the cooling block 1.
[0052] This technical solution also proposes a cooling garment (not shown in the figure) using the above-mentioned cold compress component, which is beneficial to improving the local cooling effect of the cooling garment.
