The industrial control circuit board of the portable juice cup is the "brain" of the device. Its core control logic and motor drive principle determine the stirring performance and user experience.
The portable juice cup has become a popular product for healthy living due to its small and portable features. As a core component, its industrial control circuit board realizes stable stirring function through precise control logic and efficient motor drive. A deep understanding of its core control logic and motor drive principle is not only helpful for product research and development upgrades, but also provides a theoretical basis for users to understand the device operation mechanism.
The industrial control circuit board of the portable juice cup is mainly composed of a power management module, a microcontroller (MCU), a sensor module, a motor drive module, and a user interaction module. The power management module is responsible for converting the voltage input from the battery into the stable voltage required by each component; the microcontroller, as the "hub", receives and processes signals from the sensor and user interaction modules; the sensor module monitors the motor speed, cup body status and other data in real time; the motor drive module controls the motor operation according to the microcontroller instructions; and the user interaction module realizes operations such as start, stop, and mode selection. These modules work together to form a complete control system.
The core control logic revolves around user operations and device status. When the user starts the juice cup by touching a button or a physical switch, the user interaction module transmits a signal to the microcontroller. After receiving the start command, the microcontroller first checks the device status fed back by the sensor, such as whether the cup lid is tightened and whether there are ingredients in the cup. After confirming that the device is in a safe working state, the microcontroller sends a corresponding control signal to the motor drive module according to the preset program or the stirring mode selected by the user (such as normal stirring, crushed ice mode), and adjusts the motor speed and running time. During the stirring process, the sensor continuously monitors the motor speed and device status. Once an abnormality occurs (such as motor stalling, overheating), the microcontroller immediately sends a command to stop the motor operation and issues an alarm through an indicator light or a buzzer to ensure safe use.
Portable juice cups mostly use brushless DC motors (BLDC), and their drive circuits are generally composed of power MOSFETs, driver chips, and filter circuits. The driver chip receives the PWM (pulse width modulation) signal output by the microcontroller, controls the on and off of the MOSFET by changing the duty cycle of the PWM signal, and then adjusts the voltage across the motor to achieve precise control of the motor speed. The filter circuit is used to eliminate high-frequency noise in the power supply to ensure stable operation of the motor. For example, when the motor speed needs to be increased, the duty cycle of the PWM signal output by the microcontroller increases, the driver chip controls the MOSFET conduction time to be longer, the voltage at both ends of the motor increases, and the speed increases accordingly.
To ensure the stability of the motor speed, industrial control circuit boards often adopt closed-loop control strategies. The speed sensor (such as the Hall sensor) detects the actual speed of the motor in real time and feeds the signal back to the microcontroller. The microcontroller compares the actual speed with the preset speed. If there is a deviation, the motor speed is corrected by adjusting the duty cycle of the PWM signal. This closed-loop control method can effectively compensate for speed fluctuations caused by load changes, power supply fluctuations and other factors, ensuring that the juice cup can maintain a stable stirring effect when stirring ingredients of different hardness.
The industrial control circuit board has designed corresponding control logic for a variety of abnormal situations. When the motor is detected to be overheated, the temperature sensor transmits a signal to the microcontroller, and the microcontroller immediately reduces the motor speed or stops running, and starts the heat dissipation mechanism (such as fan heat dissipation); if the motor is blocked, the current sensor detects abnormal current, and the microcontroller quickly cuts off the motor power supply to prevent the motor from burning; when the cup cover is not tightened, the position sensor feeds back a signal, and the microcontroller prohibits the motor from starting to avoid juice splashing and causing safety hazards. These exception handling logics effectively improve the safety and reliability of the juice cup.
The core control logic and motor drive principle of the portable juice cup industrial control circuit board realize stable and efficient stirring function through multi-module collaborative work and precise signal processing. With the development of technology, industrial control circuit boards will develop in the direction of higher integration and stronger intelligence in the future, such as introducing AI algorithms to optimize stirring modes and using more advanced sensors to achieve precise control, etc., to bring users a better user experience.
