The device includes an inner sheath and an outer sheath; both the inner and outer sheaths are elastic cylindrical bodies. The inner sheath has a central hole in the middle of its front side, and four sets of elastic straps for attaching ice packs are provided on the outer side of the inner sheath. These four sets of straps are respectively arranged on the top, bottom, left, and right sides of the central hole. The outer sheath covers the outer periphery of the inner sheath, and the upper and lower edges of the outer sheath are detachably connected to the upper and lower edges of the inner sheath.

The return pipe 6 is connected to the other end of the heat-conducting circulation pipe 2.

[0028] A drive motor 7 is installed on the lower surface of the water storage tank 3. The power output end of the drive motor 7 penetrates the bottom cavity wall of the water storage tank 3, and the power output end of the drive motor 7 is connected to a stirring paddle 8.

[0029] The lower surface of the water storage tank 3 is embedded with a semiconductor cooling chip 9, which is arranged in a ring at equal intervals.

[0030] It should be noted that the circulating water pump 5 draws coolant from the water storage tank 3 and injects it into the heat conduction circulation pipe 2 through the connecting pipe 4. Then, the coolant is returned to the water storage tank 3 through the return pipe 6. By continuously circulating the coolant, heat can be carried away from the knee joint through the heat conduction circulation pipe 2, thus achieving a cooling effect on the knee joint. At the same time, the semiconductor cooling chip 9 releases cold energy into the coolant, and the drive motor 7 drives the stirring paddle 8. The stirring paddle 8 agitates the coolant, which can achieve rapid cooling of the coolant and keep the coolant at a lower temperature, thereby improving the cooling effect on the knee joint.

[0031] In this embodiment, as Figure 3 As shown, support hoops 12 are provided in the middle of both sides of the cold compress band 1. The support hoops 12 are used to support the arched structure in the middle of the cold compress band 1.

[0032] It should be noted that the cold compress band 1 is supported by the support hoop 12, which can form an arched structure and reduce the pressure of the cold compress band 1 on the knee joint.

[0033] In this embodiment, as Figure 3 As shown, a sanitary pad 13 is movably provided on the lower surface of the arched structure of the cold compress band 1, a Velcro 14 is sewn onto the upper surface of the sanitary pad 13, and a Velcro 15 is sewn onto the lower surface of the arched structure of the cold compress band 1, with the Velcro 15 and the Velcro 14 being adhered together.

[0034] It should be noted that the lower surface of the cold compress band 1 comes into contact with the skin of the knee joint through the sanitary pad 13, which can improve the hygiene during use. At the same time, the sanitary pad 13 is fixed by the Velcro 14 and the Velcro 15, which can facilitate quick replacement of the sanitary pad 13.

[0035] In this embodiment, as Figure 2 As shown, heat dissipation fins 10 are installed on the lower surface of the semiconductor cooling chip 9, and heat dissipation fans 11 are installed on the surface of the heat dissipation fins 10.

The support hoop 12 is located on both sides of the cold compress band 1, and the middle part of the cold compress band 1 can fully fit the skin of the knee joint. The circulating water pump 5 draws coolant from the water storage tank 3 and injects it into the heat conduction circulation pipe 2 through the connecting pipe 4. Then, the coolant is returned to the water storage tank 3 through the return pipe 6. By continuously circulating the coolant, the heat at the knee joint can be removed through the heat conduction circulation pipe 2, realizing the cold compress on the knee joint. At the same time, the semiconductor cooling chip 9 releases cold energy into the coolant, driving the motor 7. The stirring paddle 8 is driven to agitate the coolant, which can quickly cool the coolant and keep it at a low temperature. The temperature display 16 and temperature sensor 17 work together to monitor the coolant temperature in real time, which can improve the cooling effect on the knee joint. The cooling fan 11 and cooling fins 10 work together to cool the semiconductor cooling chip 9. The lower surface of the cooling pad 1 comes into contact with the skin of the knee joint through the sanitary pad 13, which can improve the hygiene during use. At the same time, the sanitary pad 13 is fixed by Velcro 14 and Velcro 15, which can facilitate quick replacement of the sanitary pad 13.
