An Induction Spray-Type Disinfection Device

Currently, the main disinfection method used in public places involves using bottle-style disinfectants, which require manual pressing that increases contact and infection risk between individuals. Additionally, the quantity of disinfectant dispensed cannot be controlled. Moreover, existing intelligent disinfection devices in the market are expensive and have limited usability. This study proposes an induction spray-type disinfection device that utilizes infrared detection to sense human presence. It employs a miniature water pump to draw the disinfectant and spray it out through a high-pressure nozzle, achieving contactless and automated disinfection, thereby significantly improving disinfection efficiency. The proposed device is compact, lightweight, portable, and applicable in various scenarios. It can operate independently without external force and is easy to use. The contactless disinfection method avoids cross-contamination, ensuring safety and reliability. The device has a long lifespan and low cost, thus showing promising prospects in the disinfection market.
