DC Rechargeable Table & Stand Fan Controller PCB Solution

1. Product Overview

This product series consists of two mature control circuit boards for DC rechargeable desk fans and pedestal fans, covering model HSH-FS01-MAIN and HSH-SF1803R. The integrated PCB integrates battery charging management, DC fan motor drive, digital display, multi-speed wind control, timing setting and human interaction modules. It acts as the complete core electronic control solution for rechargeable household table fans and stand fans.

2. Product Model List

  1. HSH-FS01-MAIN
  2. HSH-SF1803R

3. Core Built-in Functional Modules

3.1 DC Charging Management Circuit

Independent charging control circuit matches lithium battery packs of rechargeable fans. It monitors charging voltage and current in real time, equipped with corresponding protection components to regulate the whole charging process.

3.2 Multi-Gear Wind Speed Control

Multiple physical key terminals are reserved on the board to realize adjustable wind speed modes, meeting different air volume demands for daily indoor cooling.

3.3 Digital Display & Status Indication

Both versions carry digital number display screens. One supports segmented LED lamp status indication, the other adopts integrated touch display panel. It can visually present working time, gear status and battery power level for end users.

3.4 Timing Shutdown & Function Selection

Support customized timing operation function, with dedicated keys for mode switching such as normal wind and sleep wind. Built-in buzzer provides sound feedback for each operation.

3.5 Multi-Layer Safety Protection Circuit

The circuit layout includes overcharge, overdischarge, overcurrent and short-circuit protection circuits, which effectively lower abnormal operation risks during fan charging and running.

3.6 Reserved USB Output Port (HSH-FS01-MAIN)

HSH-FS01-MAIN reserves USB power output interface, enabling the fan to supply emergency power to small digital devices when fully charged, expanding product practical functions.

4. Core Advantages of This Solution

4.1 Two Models for Different Product Positioning

The two PCBs adopt different panel designs: one with separate digital tube + LED indicator layout, the other with integrated touch display panel. Manufacturers can select the matched board according to their fan’s appearance structure, functional configuration and product cost positioning without secondary circuit development.

4.2 All-in-One Integrated Circuit Design

Single PCB unifies charging management, motor drive, display control and key interaction, replacing scattered separate modules. It simplifies the internal wiring structure of finished fans, reduces assembly steps and cuts the procurement types of spare parts.

4.3 Customized PCB Outline for Fan Internal Installation

Specially shaped PCB outlines are tailored to fit the installation cavity of mainstream DC rechargeable table fans and stand fans. Standardized pin terminals support automated assembly lines, improving factory production efficiency.

4.4 Stable Circuit Performance with Mature Mass Production Process

All components adopt standardized matching schemes verified by batch production. The circuit maintains stable output under long-time continuous operation, and complete protection circuits assist finished fans in passing conventional household electrical safety certification tests.

4.5 Flexible OEM Matching Support

Ready-made stock of the two models can support mass order supply. Minor function and parameter adjustments are acceptable based on manufacturers’ customized fan development demands.

5. Application Scope

This series of control boards are exclusive matching electronic spare parts for DC rechargeable table fans and vertical stand fans. Applicable scenarios include new rechargeable fan product R&D, replacement maintenance accessories for finished fans, and supporting PCB components for home appliance OEM & ODM manufacturers, suitable for portable indoor cooling fans for household use.

6. Commercial Value for Fan Manufacturers

  1. Two finished mature models save independent circuit development cycle and related R&D costs for factories.
  2. Integrated multi-function design reduces accessory quantity, lowering material procurement and manual assembly costs.
  3. Verified stable circuit structure ensures consistent performance of each production batch and reduces after-sales maintenance rate.
  4. Customized PCB size fits most existing fan shell structures, requiring no large-scale modification of original production molds.
