Meanwhile, the exhaust valve 34 can also be used to release residual gas in the system after cleaning to ensure safety; the carbon dioxide outlet pipe 328 connected to the other side of the four-way connecting pipe 326 can be used to discharge excess carbon dioxide gas to ensure internal pressure balance of the system; the diversion pipe 329 connected to the carbon dioxide liquid outlet pipe 324 can distribute carbon dioxide to multiple cleaning nozzles or different cleaning areas to improve cleaning efficiency and coverage; the diversion pipe 329 evenly distributes carbon dioxide to multiple cleaning points to ensure that all parts that need cleaning can be thoroughly cleaned, improving the overall cleaning effect; the multi-outlet structure allows different parts to be sprayed simultaneously during the cleaning process, reducing cleaning time and improving efficiency.

[0038] Please refer to Figure 5 and Figure 8 The cleaning component 33 includes a first cleaning nozzle 330 mounted on a support plate 31, a position adjustment part 331 mounted on one side of the first cleaning nozzle 330, and a second cleaning nozzle 332 mounted on the position adjustment part 331; the first cleaning nozzle 330 and the second cleaning nozzle 332 are respectively connected to the diversion pipe 329. The first cleaning nozzle 330 and the second cleaning nozzle 332 are installed in different positions, allowing for multi-angle cleaning of parts to ensure a more comprehensive and thorough cleaning. Both nozzles are connected to the diversion pipe 329, enabling the spraying of cleaning fluid from multiple directions and positions, ensuring uniform cleaning of every part and improving the cleaning effect. The position adjustment unit 331, installed on one side of the first cleaning nozzle 330, allows for flexible adjustment of the position of the second cleaning nozzle 332, adjusting the cleaning angle and position according to actual needs. This position adjustment function allows the cleaning part 33 to adapt to parts of different shapes and sizes, improving the applicability and flexibility of the equipment. The first and second cleaning nozzles spray cleaning fluid separately, allowing for simultaneous cleaning of multiple parts, shortening cleaning time and improving cleaning efficiency. The coordinated operation of the two cleaning nozzles makes the cleaning process more continuous and efficient, reducing cleaning interruptions and adjustment time.

[0039] Please refer to Figure 7 and Figure 8 The second cleaning nozzle 332 includes a rotating rod 332A rotatably mounted on the position adjustment part 331, a cleaning head 332B mounted on the rotating rod 332A, a carbon dioxide inlet pipe 332C mounted on the cleaning head 332B and communicating with the diversion pipe 329, and an air inlet pipe 332D mounted on the cleaning head 332B for communicating with air. The installation of the rotating rod 332A allows the second cleaning nozzle 332 to rotate freely within a certain range, adjusting the cleaning angle and ensuring that the cleaning head 332B can cover more cleaning nozzle positions. The direction of the cleaning head 332B can be flexibly adjusted by the rotating rod 332A to adapt to parts of different shapes and sizes, improving cleaning coverage and effectiveness. The carbon dioxide inlet pipe 332C installed on the cleaning head 332B is connected to the diverter pipe 329, ensuring that the cleaning head 332B can continuously obtain sufficient carbon dioxide, improving the impact and dissolving power of the cleaning fluid. The air inlet pipe 332D installed on the cleaning head 332B can introduce air, which mixes with carbon dioxide to form a gas-liquid mixture spray, enhancing the cleaning effect. The gas-liquid mixture jet can generate a stronger physical impact force, effectively removing stubborn stains and deposits; through the coordinated work of the carbon dioxide inlet pipe 332C and the air inlet pipe 332D, multi-point jetting can be achieved, improving cleaning speed and efficiency; the structure of the rotating rod 332A allows the cleaning head 332B to continuously adjust its direction, achieving continuous cleaning and reducing cleaning interruptions and adjustment time.

[0040] The second cleaning nozzle 332 also includes a heating wire 332E disposed on the cleaning head 332B; the cleaning component 33 also includes an ESD cleaning nozzle 35 mounted on the support plate 31. The heating wire 332E mounted on the cleaning head 332B heats the cleaning fluid, increasing its temperature. The high-temperature cleaning fluid more effectively dissolves and removes stubborn stains, especially grease, wax, and other substances requiring higher temperatures for effective cleaning. Combined with the air inlet pipe 332D and the carbon dioxide inlet pipe 332C, the heated gas-liquid mixture spray generates a stronger physical impact at high temperatures, further enhancing the cleaning effect. The use of the heating wire 332E speeds up the cleaning process because the high-temperature cleaning fluid dissolves stains more quickly, reducing cleaning time. The structure of the rotating rod 332A allows the cleaning head 332B to continuously adjust its direction, achieving rapid and comprehensive cleaning in conjunction with the heating wire 332E. The flexible rotation of the rotating rod 332A and the use of the heating wire 332E ensure that the cleaning head 332B can cover more cleaning nozzle positions, reducing blind spots. By adjusting the direction and position of the cleaning head 332B, combined with the heating effect, it can cover every corner and hidden part of the component, improving the comprehensiveness of the cleaning.
