AI Technical Summary
Existing sterilization and disinfection devices can only perform sterilization and disinfection in a single way, which cannot meet multiple sterilization and disinfection needs, resulting in low equipment utilization and high purchase costs.
A multifunctional microwave sterilization and disinfection device is designed, integrating microwave sterilization components, steam sterilization components, and ultraviolet sterilization components. Multiple sterilization methods are integrated through multi-layer breathable shelves, cut-off waveguide vents, and light-transmitting holes, thereby improving the flexibility and sterilization efficiency of the equipment.
It enables the selection of multiple sterilization and disinfection functions such as microwave, steam and ultraviolet light, which improves equipment utilization and the flexibility of sterilization treatment, and reduces equipment purchase costs.
