AI Technical Summary
⚠Technical Problem
Existing abrasion protection helmets rely on separate manifold systems for their airflow control systems, resulting in high complexity, high cost, increased weight, and discomfort when worn.
⚗Method used
It adopts a sandwich dual-air duct design, which uses the inner liner and the inner wall of the helmet body to form a sandwich air duct. The air duct is connected to the air purification and air supply device through the air inlet and air outlet, providing directional airflow protection, reducing the use of extra materials and improving adaptability.
🎯Benefits of technology
It achieves more cost-effective, lighter, and more comfortable airflow protection, effectively preventing dust and other pollutants from entering and providing a continuous airflow barrier.
