AI Technical Summary
The ultraviolet irradiation method of traditional clean benches causes the bottom and lower sides of experimental vessels or items on the workbench to become sterilization blind spots, affecting the sterilization effect and experimental safety.
The system combines a quartz glass worktable with an aluminum film reflector. The aluminum film reflector is driven by a motor to rotate, forming a scanning reflection light path. Combined with ventilation and heat dissipation channels and a controller to control the on/off of ultraviolet lamps and fluorescent lamps, it ensures all-round disinfection.
It completely eliminates blind spots in disinfection, improves the cleanliness and uniformity of disinfection on the work surface, prevents equipment from overheating and dust from entering, and provides a convenient experimental environment.
