Operating Principle: The fog of the essential oil sprayed by the diffuser flows with the air, which helps to easily distinguish the single component of the compound essential oil or the different origin, grade, and purity of the single essential oil. So it is essential equipment for aroma therapists. This technology does not use water or diluted essential oils, atomizes pure essential oils directly into particles, and diffuses them into the air through a high-pressure air pump. Due to the use of pure essential oils, the odor concentration is very high and the diffusion is very fast. The operation is very simple, because there is no need to add water every day. No cleaning is needed. Multiple modes can meet your demands. Intermittent working mode does not bring olfactory fatigue caused by continuous inhalation of essential oils and avoids the excessive use of essential oils. There are three intelligent modes: Mode 1: 10 minutes of continuous. Mode 2: 5 minutes continuous diffusion, followed by 2 minutes rest 15 seconds work 78 Cycles, automatic shut-off after 3 hours. Mode 3: 2 minutes continuous diffusion, followed by 10 minutes rest 30 seconds work 34 Cycles, automatic shut-off after 6 hours.
