Interchangeable scent chambers and machine-readable drum alignment enable precise electronic scent selection without fixed cartridge layouts.
A gear-and-rack lifting structure exposes the essential oil bottle for quick replacement while simplifying the diffuser housing and lowering production cost.
A liquid collecting tank encloses the atomizing core to limit topple leakage, protect electronics, and keep fragrance atomization stable.
A spring-loaded oil needle and universal oil control module regulate essential oil dripping to improve atomization and reduce leakage.
A detachable spray module, silicone sealing, and shock-absorbing pads help an airflow pump diffuser prevent oil leaks, cut noise, and keep mist uniform.
High-speed airflow and a dual-tube pressure-balancing structure prevent oil overflow during atomizer replacement while lowering diffuser cost.
Catalytic or UV activation of aqueous oxidizers with ozone boosts pathogen kill at lower doses, shortens contact time, and enables faster room re-entry.
