Warm Cleansing Instrument Solution
  • Warm Cleansing Instrument Solution
    1. Overview of the plan
    The PCBA solution for the warm facial cleansing device utilizes a microcontroller to adjust the duty cycle of the PWM signal, thereby controlling the motor speed and the temperature of the heating element. Through mechanical design, it achieves the effects of warming, moisturizing, cleansing, and brightening the skin.
    2. Scheme characteristics
    42℃ constant temperature heating
    High-speed vibration at 4000 rpm
    Standby current < 3uA
    Adopting a 32-bit low-power MCU facilitates the development of extended functionalities
