AI Technical Summary
Traditional fragrance diffusers only have a single type of essential oil built in, and users have to manually change the fragrance, which is cumbersome and can easily lead to a muddy scent after the change.
A replaceable fragrance diffuser was designed, comprising an automatic essential oil replacement component and a cleaning component. The automatic switching and cleaning of essential oils is achieved by a servo motor driving the rotating parts, an electric valve controls the flow of essential oils and cleaning liquid, and a micro pump achieves negative pressure cleaning.
It enables automatic replacement and deep cleaning of essential oils, simplifies the operation process, avoids the murky smell caused by mixing new and old essential oils, and improves the user experience.
