Cross-infection through contact with objects carrying the SARS-CoV-2 pathogen is not uncommon during outbreaks. DING-DONG is a doorbell with inner and outer rollers, which are sterilized by rotating. The touched side will be screwed into the interior for disinfection, and the clean side will be rotated out as a replacement to ensure that every time the user presses the doorbell, it is clean and virus-free, thus effectively avoiding the potential danger of cross-infection.
