AI Technical Summary
Traditional liquid fragrance containers cannot dynamically adjust the amount of evaporation according to environmental needs or human activities, resulting in uncontrollable fragrance concentration, small diffusion range, inconvenience of use, and lack of intelligent management.
Infrared sensors are used to detect human activity, and a microcontroller controls the pump to spray fragrance. A variable-speed fan adjusts the diffusion range, and an electric heating wire heats the liquid fragrance, achieving controllability of range and concentration. A servo motor adjusts the spray direction.
It enables controllable range and concentration of fragrances, avoids waste, provides intelligent air freshening management, and adapts to different scenario needs.
