The control board of the juice juicer mixer is the core control unit of the equipment, mainly responsible for motor drive, function adjustment and safety protection and other functions. The following is a detailed description of its main functions:

Motor control

Start/stop control: The on-off of the motor is controlled through relays, thyristors (TRIAC), or MOSFETs.

Speed regulation: It adopts PWM (Pulse width modulation) or voltage regulation methods to achieve multi-speed change or stepless speed regulation.

Forward and reverse control (for some models) : Some mixers support forward and reverse mixing to prevent food from getting stuck in the blades.

2. Speed adjustment

Multi-speed regulation: Select the preset speed (such as low speed, medium speed, high speed) through buttons or knobs.

Stepless speed regulation (high-end models) : Users can smoothly adjust the rotational speed to meet the needs of different food ingredients.

Pulse mode: Short-term high-speed stirring, suitable for harder ingredients (such as ice cubes, nuts).

3. Safety protection function

Overheat protection: The temperature sensor monitors the motor temperature and automatically cuts off the power when it exceeds the threshold.

Overcurrent protection: Detects the motor current to prevent motor burnout due to locked rotor or overload.

Lid opening protection: Do not start when the lid is not closed to avoid potential safety hazards.

Motor locked-rotor protection: Detect abnormal rotational speed (such as blade jamming) and immediately stop operation.

4. User interaction function

Key/touch control: Operated through physical keys or the touch panel.

Status display: The LED indicator light or LCD screen shows the current gear position, fault code, etc.

Timing function (for some models) : Set the working time and it will automatically stop.

5. Power Management

AC-DC conversion: Convert the mains power (220V/110V) into the low-voltage direct current (such as 5V, 12V) required by the control board.

Low-power standby: Some smart models support standby mode to reduce energy consumption.

6. Intelligent Functions (High-end Models)

Preset programs: One-click selection of modes such as juicing, stirring, and grinding.

APP/Wi-Fi control: Remotely operate or adjust parameters via mobile phone.

Automatic cleaning reminder: Remind users to clean the machine after the cumulative operation time.

Summary

The core task of the juicer blender control board is to drive the motor safely and precisely, while providing a user-friendly operation method. The functional differences among models of different price ranges mainly lie in the speed regulation accuracy, protection mechanism and degree of intelligence.
