The automotive aroma atomization solution is a compact humidification module specifically engineered for in-vehicle applications. It adopts a dedicated internal structure that enables up to 2× high water-level atomization performance compared with conventional designs, supporting long-duration continuous operation. With an increased atomization rate and expanded humidification coverage, the solution maintains stable mist output under high water-level conditions. This capability allows the system to retain a compact design while extending continuous misting time, and improving usable water storage capacity. Consequently, it reduces refill and water replacement frequency, helping to mitigate water-quality degradation and contamination risks associated with frequent refilling.
