[0026] This invention provides a portable thermotherapy device that can centrally manage and store the auxiliary accessories such as pipes and water bags that come with the thermotherapy device, significantly improving the portability and efficiency of the device. It avoids the problems of easy loss and messy storage of traditional external accessories, making clinical operation more standardized.

[0027] The following is combined with Figures 1-4 The technical solution provided by this utility model will be described in more detail.

[0028] This utility model provides a portable hot and cold therapy device including a first shell 1, a second shell 2 and a third shell 3 for protection. The third shell 3 is equipped with a collection component 4 for easy storage of objects, and the upper end of the inner wall of the first shell 1 is equipped with a cooling component 5 for cooling.

[0029] Furthermore, the first shell 1, the second shell 2, and the third shell 3 are fixedly connected to the upper end of the first shell 1 and the third shell 3, respectively. The first shell 1, the second shell 2, and the third shell 3 are mainly used to form a safe operating environment for the internal components, preventing damage to the internal components from external interference. The internal collection component 4 can collect and centrally manage the auxiliary accessories such as pipes and water bags that come with the thermotherapy device, significantly improving the portability and efficiency of the device. This avoids the problems of easy loss and messy storage of traditional external accessories, making clinical operation more standardized. The upper end of the inner wall of the first shell 1 is equipped with a cooling component 5. The cooling component 5 works in conjunction with water circulation and heat exchange, using refrigeration technology to continuously reduce the temperature of the circulating water in the closed pipeline, thereby conducting the cooled water to the treatment site to achieve local cooling, providing a stable and controllable cold source for the device, and ensuring that tissue heat can be quickly absorbed and inflammation relieved during the treatment process.

[0030] In some embodiments of this utility model, the collecting component 4 includes a guide rail 401 and a mounting port 402. Two guide rails 401 are provided, and the two guide rails 401 are fixedly connected to the lower part of the inner wall of the third housing 3. The mounting port 402 is opened on one side of the inner wall of the third housing 3 and extends to the outside and communicates with the outside. The upper ends of the two guide rails 401 are slidably connected to a storage box 403. The storage box 403 is slidably disposed in the mounting port 402. Two limiting components for fixing the storage box 403 are installed inside the third housing 3, and the two limiting components are symmetrically arranged.

[0031] Furthermore, by sliding the storage box 403 located on the upper end of the mounting port 402 and the guide rail 401, the storage box 403 can be pulled out from the third housing 3 through the mounting port 402, allowing users to store and centrally manage the auxiliary accessories such as the tubing and water bag that come with the thermotherapy device. This significantly improves the portability and efficiency of the device, avoids the problems of easy loss and messy storage of traditional external accessories, and makes clinical operation more standardized.

[0032] In some embodiments of the present invention described above, the limiting component includes a sliding cavity 404. A plurality of springs 405 are fixedly connected to the inner wall of the sliding cavity 404 away from the storage box 403. A movable plate 406 is slidably connected inside the sliding cavity 404. The movable plate 406 is fixedly connected to the front end of the plurality of springs 405. A wedge block 407 is fixedly connected to the inner wall of the movable plate 406 away from the springs 405. A limiting groove 408 is formed on one side wall of the storage box 403. The wedge block 407 penetrates the inner wall of the sliding cavity 404 and engages with the limiting groove 408.

[0033] A pull rod 409 is fixedly connected to the middle of the side of the movable plate 406 away from the wedge block 407. The end of the pull rod 409 away from the wedge block 407 passes through the third housing 3 and is fixedly connected to a toggle block 410. The toggle block 410 is slidably disposed outside the third housing 3.

[0034] Furthermore, when the storage box 403 is pulled out, the user pulls the actuating block 410, which causes the moving plate 406 to slide within the sliding cavity 404. The wedge block 407 moves out of the limiting groove 408 and is stored in the sliding cavity 404. At this time, the user can pull out the storage box 403 and take out the auxiliary accessories inside the storage box 403. When the storage box 403 is inserted, after the side wall of the storage box 403 contacts the wedge-shaped surface of the wedge block 407, the wedge block 407 tilts. By decomposing the thrust, the spring 405 can be compressed. As the storage box 403 is gradually pushed in, the limiting groove 408 on the side wall of the storage box 403 is aligned with the wedge block 407. At this time, the spring 405 returns to its original position, which allows the wedge block 407 to automatically move into the limiting groove 408. The wedge block 407, in conjunction with the limiting groove 408, can fix the storage box 403, preventing it from moving and ensuring its stability. Furthermore, the storage box 403 is easy to assemble and disassemble.

[0035] In some embodiments of this utility model, the cooling assembly 5 includes a compressor 501, a heat exchanger 502, a condenser 503, and a water storage tank 504. The compressor 501, heat exchanger 502, condenser 503, and water storage tank 504 are all fixedly installed at the bottom of the inner wall of the first housing 1. The exhaust port of the compressor 501 is connected to the refrigerant inlet of the condenser 503, and the suction port of the compressor 501 is connected to the refrigerant outlet of the heat exchanger 502. An expansion valve 505 is installed at the refrigerant outlet of the condenser 503. The hot water inlet and outlet of the condenser 503 are respectively connected to the outlet and inlet of the water storage tank 504. The refrigerant inlet of the heat exchanger 502 is connected to the outlet of the expansion valve 505, and the refrigerant outlet of the heat exchanger 502 is connected to the suction port of the compressor 501.

[0036] A cooling fan 506 is fixedly installed on the side of the condenser 503 away from the water storage tank 504.

[0037] Furthermore, compressor 501 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gas. After entering condenser 503, it is forced to dissipate heat and liquefy by cooling fan 506. The released heat is absorbed by the circulating water in water tank 504. After the liquid refrigerant is throttled and depressurized by expansion valve 505, it absorbs heat and evaporates into low-temperature gas in heat exchanger 502. It is then drawn back into compressor 501 to complete the closed-loop cycle. Ultimately, it achieves the function of transferring heat to the water in water tank 504 through refrigerant phase change. The upper end of the third housing 3 is equipped with corresponding pipe joints. The input end of the pipe joints is connected to the output end of cooling component 5. The cooled water is conducted to the treatment site through the pipe joints and auxiliary accessories to achieve local cooling, providing a stable and controllable cold source for the equipment, ensuring that tissue heat can be quickly absorbed and inflammation relieved during treatment.

[0038] In some embodiments of this utility model, ventilation ports are provided on both sides of the inner wall of the second housing 2, and the two ventilation ports are symmetrically arranged. A dust filter 6 is fixedly connected to the inner wall of each of the two ventilation ports, and the cooling fan 506 is directly opposite one of the dust filter 6.

[0039] Furthermore, the dust filter 6 can remove dust from the gas entering the second housing 2 through the air exchange port. It effectively blocks dust particles through a physical interception mechanism, preventing dust accumulation inside the equipment from causing a decrease in heat dissipation efficiency. At the same time, it can maintain the cleanliness of the internal airflow and reduce the frequency of maintenance.

[0040] In some of the embodiments of the present invention described above, a control panel 7 is installed on the upper end of the third housing 3, and a strap 8 is fixedly connected to the middle of both sides of the third housing 3.

[0041] Furthermore, the control panel 7 is used to precisely adjust treatment parameters through a touch or button interface, while the straps 8 are fixed to both sides of the third housing 3, making it easy for users to pick up and move the equipment.

[0042] Example 1:

[0043] The portable hot and cold therapy device provided by this utility model allows users to store and centrally manage auxiliary accessories such as pipes and water bags that come with the hot and cold therapy device by means of a storage box 403 that is slidably set on the upper end of the installation port 402 and the guide rail 401. This significantly improves the portability and efficiency of the device, avoids the problems of easy loss and messy storage of traditional external accessories, and makes clinical operation more standardized.

[0044] Example 2:

[0045] The difference between Embodiment 2 and Embodiment 1 is that when the storage box 403 is pulled out, the user pulls the actuating block 410, which causes the moving plate 406 to slide within the sliding cavity 404. The wedge block 407 moves out of the limiting groove 408 and is stored in the sliding cavity 404. At this time, the user can pull out the storage box 403 and take out the auxiliary accessories inside the storage box 403. When the storage box 403 is inserted, after the side wall of the storage box 403 contacts the wedge-shaped surface of the wedge block 407, the wedge block... The inclined surface of 407 decomposes the thrust, which causes the spring 405 to contract. As the storage box 403 is gradually pushed in, the limiting groove 408 on the side wall of the storage box 403 is aligned with the wedge block 407. At this time, the spring 405 returns to its original position, which allows the wedge block 407 to automatically move into the limiting groove 408. The wedge block 407, in conjunction with the limiting groove 408, can fix the storage box 403, preventing it from moving and ensuring its stability. Furthermore, the storage box 403 is easy to assemble and disassemble.
