3. Core Functional Modules

3.1 DC12V Stable Drive Circuit

Standard 12VDC 2A constant output circuit matches the power demand of box fan DC motors. Equipped with filter capacitance and inductance components to suppress current ripple, enabling smooth and steady fan rotation without obvious speed fluctuation.

3.2 Built-in Charging Management Circuit

Integrated charging control circuit works with the fan’s built-in lithium battery pack. It monitors charging voltage and current throughout the process to maintain a standardized charging cycle for rechargeable fans.

3.3 Multi-Gear Wind Speed Control & Indication

Reserved multi-speed control terminals and matched LED indicator lights support multiple adjustable wind modes, with clear light feedback to display the current running gear for users.

3.4 Operation Prompt Buzzer

Onboard buzzer component sends short sound prompts when users switch wind speeds or adjust modes, realizing simple human-machine interaction.

3.5 Comprehensive Circuit Safety Protection

The PCB layout integrates over-current, over-voltage, short-circuit and abnormal charging protection circuits, which reduce potential safety risks during fan charging and continuous operation.

4. Solution Advantages

4.1 Specialized PCB Shape for Box Fan Installation

The curved strip PCB outline is customized to fit the internal installation cavity of mainstream DC rechargeable box fans. Standard unified wiring terminals simplify assembly steps and adapt to automated production lines of home appliance factories.

4.2 All-in-One Integrated Circuit Design

Single PCB integrates motor drive, charging control and status display functions, replacing separated discrete modules. It reduces the types of spare parts needed for finished fan assembly, cutting material procurement and labor assembly costs.

4.3 Mature & Stable Mass Production Circuit Scheme

All electronic components adopt standardized matching verified by batch production. The circuit maintains stable performance under long-term continuous operation, and the complete protection design helps finished box fans pass routine household electrical safety tests smoothly.

4.4 Standard DC12V Wide Matching Compatibility

12VDC 2A, 24W rated specification fits most mainstream DC rechargeable box fan motor configurations. Manufacturers can directly adopt this board without extra circuit modification for most existing box fan product lines.

4.5 Convenient OEM & Bulk Supply Support

The ready-made HSH-SF05-002 model supports stable bulk order delivery. We accept minor circuit parameter adjustments according to manufacturers’ customized box fan function demands.

5. Application Scope

This control board is exclusively supporting electronic spare parts for DC rechargeable box fans. It can be applied as core control hardware for new box fan product development, replacement maintenance circuit boards for finished rechargeable box fans, and matching PCB accessories for small home appliance OEM & ODM manufacturers, suitable for portable indoor cooling box fans used in bedrooms, offices and travel scenarios.

6. Practical Value for Fan Manufacturers

  1. Finished mature circuit board eliminates independent R&D work, shortening the development cycle of new rechargeable box fan products.
  2. Integrated multi-function design reduces the number of assembly parts, lowering overall production costs.
  3. Verified stable circuit performance helps lower the after-sales failure rate of finished fans.
  4. Customized curved PCB size matches mainstream box fan shell structures, requiring no large-scale mold revision for existing production lines.
