AI Technical Summary
The UV sterilization and disinfection structure of hand sanitizers poses a risk of ultraviolet leakage when hands are near them, especially when the device's sensing system is delayed or in a blind spot. This could lead to skin redness or corneal burns and increase the risk of photoaging in the long term.
A structure including a push block, a spring, a sensor, and a UV lamp is designed. When a hand is placed on the side of the hand sanitizer dispenser, the push block pushes the spring to move, the sensor detects the hand and turns off the UV lamp, while the soft pad on the push block prevents impact, the UV lamp moves inward to avoid direct irradiation, and the nozzle sprays hand sanitizer.
It effectively prevents hand irradiation when UV lamps fail to turn off in time or when sensors malfunction, preventing skin redness or corneal burns, reducing the risk of photoaging, and improving equipment safety.
