Helmets can ensure safety while riding, but they can also pose a hidden danger in rainy weather. Because the rain and breathing vapor will stick to the transparent mask, obstructing vision and causing traffic accidents. The media pointed out that the frequency of traffic accidents in the rain is five times higher than in sunny weather.
High-speed airflow is emitted through a fan placed at the brim of the helmet. The airflow barrier is able to block the wind and rain without affecting the sight.A sensor at the front senses the wind speed ahead. The speed of the emitted airflow is instantly adjusted according to the wind speed.
