Professional custom Diffuser circuit board supplier. Our self-developed Tri-Sync Precise AFT Tracking technology solves three common defects of ordinary 2.4MHz AFT control boards, achieving uniform mist output, low-temperature ultra-quiet operation and dual anti-dry-burn protection. We offer full one-stop services from design scheme, R&D prototype to mass production. All products meet EMC requirements and comply with global safety certifications.
Ordinary Diffuser circuit board on the market has three stubborn technical defects:
1. Unstable mist output, and the mist volume gradually declines after long-term use.
2. The board easily generates heat with loud resonance noise, resulting in high after-sales failure rate.
3. Unreliable water shortage protection, bringing high risk of dry-burn damage to the machine.
We equip our Diffuser circuit board with exclusive Tri-Sync Precise AFT Tracking technology to completely solve all industry pain points.
1. Long-lasting uniform fine mist, less residue and stains
The system synchronously monitors current, phase and water temperature to maintain the optimal vibration state. It fully atomizes pure water and high-viscosity essential oil, keeping stable mist volume without attenuation for long-term operation.
2. Low power, low temperature and ultra-quiet operation, double service life
Precise automatic frequency matching eliminates redundant power consumption, effectively reduces overall operating temperature and working noise, and greatly extends the service life of the diffuser equipment.
3. Dual safety detection, effectively prevent mis-shutdown and dry burn
Adopts dual detection of capacitive water level sensing and vibration load identification. Limescale and thick essential oil will not interfere with water level judgment. The board cuts off power instantly when water is insufficient. It is safe for bedroom and nursery use, and fully meets strict European and American small appliance safety standards.
We provide complete full-process one-stop supporting services for customized Diffuser circuit board and Aroma diffuser PCB projects.
We support overall technical services including solution design, prototype research and development, function customization and mass production delivery. All products meet standard EMC requirements and pass global mainstream safety certifications, with stable and reliable batch quality.
