Ultrasonic Cool Mist Humidifier Electronic Control Assembly: Engineered for ultrasonic residential humidifiers, aroma diffusers, and commercial atomization appliances. Powered by an 8-bit high-performance industrial MCU, this dual-board controller set features a power drive motherboard linked via ribbon cable to an LED indicator daughter board. Directly drives 118kHz microporous atomizing sheets and 1.5MHz~2.0MHz high-frequency piezoelectric ceramic transducers, manages DC air dispersion fan speeds, and integrates essential dry-burn water shortage protection.
Performance & Verification
| Parameter | Result / Accuracy | Notes |
|---|---|---|
| Atomizing Transducer Frequency | 118 kHz / 1.5 MHz ~ 2.0 MHz | Dual-Mode Supported (Pending Confirmation) |
| Water Shortage Protection Latency | Automatic Dry-Burn Cutoff | Probe Monitored (Pending Confirmation) |
| Microcontroller Architecture | 8-Bit Industrial MCU | Firmware Configured (Pending Confirmation) |
| Peripheral Fan Output | DC Brushless Fan Speed Drive | Multi-Gear Airflow (Pending Confirmation) |
| Smart Memory & Lock Functions | Power-Down Memory & Child Lock | EEPROM Integrated (Pending Confirmation) |
Note: Performance results were obtained under controlled laboratory conditions. Actual performance may vary depending on test conditions, water quality, mineral content, transducer aging, and thermal dissipation environment. Test reports are available upon request.
Engineering Highlights
01. Broad-Spectrum Ultrasonic Driver
Versatile oscillating output circuitry powers low-frequency 118kHz microporous atomization discs as well as 1.5MHz~2.0MHz high-frequency ceramic piezoceramic discs.
02. Fail-Safe Dry-Burn Protection
Integrated water level sensing circuitry automatically shuts off the high-frequency drive whenever the reservoir runs dry, preventing thermal damage to the transducer disc.
03. Capacitive Touch & Remote Keypad
Features elevated capacitive touch spring pillars on the motherboard along with a detachable multi-LED tactile push-button daughter board linked via flexible ribbon wire.
04. Complete Appliance Control Logic
Firmware incorporates multi-step timer shutdown, safety child lock, power-down state memory, and intelligent over-temperature cutoffs for consumer-ready compliance.
