[0002] With the rapid development of medical technology, various medical consumables are increasingly widely used in clinical treatment. These medical consumables must undergo a strict cleaning process after use to ensure their safety and reusability. Spray technology, as a key component of medical consumable cleaning machines, plays a core role in the entire cleaning process. It removes dirt, bloodstains, microorganisms, and other impurities from the surface of medical consumables by spraying cleaning solutions onto them and using the impact force and chemical action of the liquid. In recent years, the design of spray components has been continuously improved and innovated, aiming to improve cleaning efficiency, optimize cleaning effects, and reduce operating costs.

[0003] There are many types of medical consumables cleaning machines on the market. Most of these machines have spray units that can only spray in one direction. Due to the limited water volume, when immersion washing is required, the addition of cleaning water cannot be done quickly. The time required to fully immerse the medical consumables using water from the spray nozzles is too long, affecting the effectiveness of use and causing inconvenience to users. Therefore, we propose a spray unit for medical consumables cleaning machines. Utility Model Content
