With the continuous growth of the market for aromatherapy diffusers, small humidifiers and landscape fogging products, ultrasonic atomization modules serve as core components. The reliability of complete units, consistency of fog output and safety protection have become key factors for product competitiveness. Many failures of atomization equipment do not stem from the atomizing disc itself, but from design defects in the driving PCBA circuit. Dongguan Hanyi Electronics specializes in the R&D of control boards for small household appliances. Targeting the pain points of ultrasonic atomization applications, we have optimized the complete PCBA solution for atomization modules.

Traditional simple atomization driver boards often suffer from dry-burn damage, unstable fog output, severe electromagnetic interference and false water level detection. Hanyi carries out targeted optimization at the circuit design stage: optimizing the high-frequency driving loop to reduce signal loss and ensure stable resonance of the atomizing disc; improving the liquid level sampling circuit to adapt to both clear water and essential oil-containing liquids and reduce false triggering; strengthening EMC circuit design to meet domestic and overseas electromagnetic certification requirements and prevent complete products from failing certification.

Industry Pain Points Addressed by Hanyi’s Atomization Module PCBA Solution

✅ Dry-burn protection for water shortage: Accurate liquid level detection automatically cuts off atomization output when water runs out to protect the atomizing disc and reduce after-sales repair rates ✅ Stable and controllable fog output: PWM fog adjustment is supported to enable multi-level fog switching for customers ✅ Compatible with various liquids: Suitable for clear water and water-soluble aromatherapy liquids, with anti-corrosion circuit protection design ✅ Intelligent expansion: Reserved MCU interfaces support extended functions such as timing, lighting, APP network connection and temperature & humidity linkage
