  2. Multi-Speed Fan Speed Control
     
    Each PCB reserves multi-speed control terminals to support adjustable wind speed modes, meeting different air volume demands of daily use.
  3. Working Status Indication Module
     
    Equipped with LED indicator lights to display power-on state, charging progress and running mode for intuitive user feedback.
  4. Timing & Buzzer Prompt Function
     
    Selected models carry digital display screens and buzzer reminder components, supporting timing shutdown setting and operation sound prompts to enrich human-machine interaction.
  5. Complete Safety Protection Design
     
    Built-in overcharge, over-discharge and short-circuit protection circuits to reduce potential safety hazards during fan charging and operation.

4. Solution Advantages

4.1 Diversified Model Selection for Different Product Designs

Four alternative PCB versions cover different structural and functional requirements of rechargeable table fans and stand fans. Manufacturers can select matched boards according to their fan’s internal space, function configuration and cost positioning, without extra circuit redevelopment.

4.2 Integrated Charging & Driving All-in-One Circuit

Single circuit board integrates battery charging management and fan motor drive, replacing separated discrete modules. It simplifies the internal wiring layout of finished fans, lowers assembly difficulty and cuts accessory procurement costs.

4.3 Standardized Structural Layout for Mass Production

Each controller features unified strip-shaped PCB outline, which fits the installation cavity of most mainstream rechargeable desk & pedestal fans. Standardized reserved pin positions support automated assembly and improve factory production efficiency.

4.4 Stable Circuit Performance with Mature Process

All models adopt standardized electronic component matching and mature mass production technology. The circuit maintains steady output during long-time fan operation, and the built-in multi-layer protection circuit helps finished fans pass conventional household electrical safety tests.

4.5 Flexible OEM & Customization Support

This serial solution can adapt to various specifications of DC rechargeable fans. We provide stable bulk supply of existing models, and support targeted minor circuit adjustments according to manufacturers’ customized fan function demands.

5. Application Scope

This series of control boards are exclusive matching electronic parts for DC rechargeable table fans and vertical stand fans. They can be used as core control components for new fan product development, replacement spare parts of finished rechargeable fans, and supporting PCB accessories for small home appliance OEM & ODM manufacturers, suitable for household indoor portable cooling fans.

6. Manufacturer Commercial Value

  1. Multiple ready-made models shorten new fan R&D cycles and avoid high independent circuit development costs.
  2. Integrated charging & drive structure reduces the number of spare parts, saving assembly labor and material expenses.
  3. Mature mass production flow ensures stable product yield and consistent circuit performance of each batch.
  4. Standard PCB size fits mainstream fan shell structures, compatible with most existing fan production lines without large mold modification.
