Description

Purification module and helmet comprising same

The following description relates to a purification module and a helmet including the same.

A gas mask is used to prevent the absorption of toxic substances such as biochemical weapons and chemical pollutants through the respiratory tract, and is divided into military, fire, and industrial use. A conventional gas mask is composed of a gas mask, a purifier, a hood, safety glasses, and the like, but there is a possibility that a toxic substance may penetrate through the lower part of the hood during vigorous physical activity. In the case of an all-in-one gas mask such as a helmet-type gas mask with a built-in purification tank, which has been studied a lot in recent years, it can be easily and conveniently worn and has the advantage of being able to block the penetration of toxic substances at the source. However, since the gas mask has a built-in purification tank, air that has passed through the purification tank flows into the respiratory system even during normal times, not during operation, so there is a problem that unnecessary consumption of the purification tank proceeds. In particular, in the case of vigorous physical activity, the respiratory rate increases and the respiratory resistance through the purification tank also increases, making it difficult to breathe smoothly.
