Version 2 – Optimisation & Iteration / 第二版优化设计 (V2)

Release Date: January 23, 2026
Status: Completed prototype, validated through testing

Version 2 addresses the limitations identified in V1, introducing a scaled-up and structurally refined design.
Key improvements include:

Enlarged enclosure dimensions: 120 × 120 × 120 mm

Uniform corner fillets for improved structural consistency

Improved screw placement to eliminate gaps

Reserved internal space for PCB installation and cable routing

Airflow transition geometry optimized, reducing equivalent half-angle from >50° to ~30°, significantly lowering wind noise

Cost and Components:
Total cost < 100 RMB per unit. Key components:

3D printed enclosure (PLA) ~13 RMB

Sanyo 9BAM12P2J06 centrifugal blower ~50 RMB

4-pin PWM fan controller ~4.9 RMB

Custom filter elements (3 units) ~30 RMB

Wiring & connectors: XH2.54, AWG18 / 26 wires, minor cost

Testing Results: The redesigned airflow path improved acoustic performance, and the blower provides more suction than required. Future iterations may adopt lower-power fans to further reduce cost, noise, and energy consumption.

状态： 原型完成，已通过测试验证

第二版针对 V1 中发现的问题进行了优化，整体尺寸放大并改进结构设计。
主要改进包括：

外壳尺寸增加至 120 × 120 × 120 mm

四周圆角均匀化，提高结构一致性

螺丝布置优化，消除角缝

为 PCB 安装和走线预留内部空间

风道过渡几何优化，等效半角从 >50° 降至约 30°，明显降低风噪

成本与器件选型：
单机成本 < 100 元人民币。主要器件：

3D 打印外壳（PLA）~13 元

Sanyo 9BAM12P2J06 离心风机 ~50 元

4-pin PWM 风机控制器 ~4.9 元

定制滤芯（3 个）~30 元

线束与连接器：XH2.54，AWG18 / 26 线，成本较少

测试结果： 改进后的气流路径明显降低噪声，风机吸力高于实际需求。未来版本可能使用功率更低的风机，以进一步降低成本、噪声和能耗。

Air Filter --- Version V1

Version 1 – Initial Prototype / 第一版原型设计 (V1)
Release Date: January 12, 2026
Status: Functional prototype, ongoing evaluation

Version 1 is the initial prototype of the Air_Filter project, focusing on validating the core feasibility of a compact, desktop-sized soldering fume extraction device.
Key features include:

Compact modular design suitable for personal workbenches

Adequate suction for capturing soldering fumes

Modular structure for easy disassembly and maintenance

Rapid prototyping using 3D printing

The system is divided into two primary modules: the Base Module (fan mounting and structural support) and the Transmission Roll Module (airflow guidance and filtration).

Notes: This version helped identify key design limitations, including airflow noise due to sharp transition angles and structural gaps caused by minimal screw support.

发布日期： 2026 年 1 月 12 日
状态： 功能原型，持续评估中

第一版是 Air_Filter 项目的初始原型，主要用于验证紧凑型桌面焊接烟雾抽取装置的核心可行性。
主要特点包括：

模块化紧凑设计，适合个人工作台

足够的吸力可捕集焊接烟雾

模块化结构，便于拆装和维护

使用 3D 打印进行快速原型制作

系统分为两个主要模块：Base Module（风机基座，用于风机固定和结构支撑）和 Transmission Roll Module（过滤与风道模块，用于气流导向和过滤）。
