Description

Automatic air supply helmet

Technical Field

The utility model relates to the technical field of helmet equipment, in particular to an automatic air supply helmet.

Background

Headgear is a product that is widely used in the marketplace, such as cycling helmets, special environment workers helmets, and medical personnel protective apparel.

The traditional head-mounted equipment has single function, and the functions of the helmet under different environments are different, so that various helmets need to be prepared, but in the actual use process, the functions of the utilized head-mounted equipment are mostly similar, and the protection effect of the head-mounted equipment is utilized; isolating outside air or placing a collision.

Present helmet is mostly closed, and under the long-term circumstances of wearing, it is poor to lead to air cycle easily, leads to the breathing difficulty then, though also there is some helmet to match the fan, these fans mostly all play the cooling effect, all blow to facial perpendicular in addition, can influence the effect of wearing equally.

Moreover, the air contains a large amount of dust and bacteria, and the traditional helmet does not have the effect of filtering the air.

To this end, we propose an automatic blowing helmet.
