As an example, the welding work clothes are formed by stacking materials of heat-resistant material thickly to protect workers from heat generated during welding, and inserting and inserting lead, etc., to block electromagnetic waves harmful to the human body. Is heavy and outside air is not allowed to flow inside. When the worker performs work while wearing the welding work clothes formed in this way, the heat generated by the body cannot be discharged to the outside, and the worker sweats a lot, and the worker performs work in bad conditions due to the sweat generated. Therefore, there is a problem that the work efficiency is lowered and the welding defect rate is increased.

On the other hand, in industrial sites, work performed in an enclosed space is often required, and since the supply of air from the outside is not smooth, a separate supply of breathing air is essential to workers.

In particular, in the field related to ship manufacturing, entering into an enclosed space during the operation, grinding or welding is performed, and supply of fresh breathing air is essential for improving the working environment and health and efficiency of these workers.

In the past, the worker had a small air purifying device at the waist and wore a mask for supplying purified air to allow the purified air to be sucked through the air purifying device through a mask. It is difficult to breathe and requires a large amount of fresh air, but due to the problem of not being able to breathe enough air, the efficiency of the work is deteriorating. In particular, work efficiency is remarkable by breathing hot air in the summer in an enclosed work space. It is a situation that is deteriorating.

Moreover, when the work is performed on a hot day or in a place where the work space is narrow, the heat generated from the body is further increased, and the working conditions become worse.
