Fine dust is a suspended substance in the atmosphere having various complex components, and is mainly generated when fossil fuels such as petroleum and coal are burned.

Such fine dust is mainly composed of carbon, organic hydrocarbons, nitrates, sulfates, and harmful metal components, which are combustion particles, and is known to cause respiratory and cardiovascular diseases and increase mortality.

A mask that covers the mouth and nose is used as a general means of blocking fine dust, but it is inconvenient to wear and does not adhere well to the user's face, so fine dust can flow into the respiratory tract, and it is disposable and causes environmental pollution. may become

On the other hand, in order to solve this problem, technology development such as an air mask that can be worn by a user such as Korean Patent Registration No. 10-1701828 "neckband type air blower" has been performed, which is configured in the form of a neckband , It is intended to effectively block fine dust by injecting and filtering outside air and then spraying the purified air around the user's face or supplying it through a mask.

However, by spraying purified air from the neck to the face, not only can contaminated air be mixed and introduced into the respiratory tract, but also carbon dioxide generated during exhalation is generated by supplying purified air to the air supply mask through the hose connection. There was a problem of re-inhalation and the inconvenience of wearing a double mask.

On the other hand, the above-mentioned background art is technical information that the inventor possessed for derivation of the present invention or acquired in the process of derivation of the present invention, and cannot necessarily be said to be known art disclosed to the general public prior to filing the present invention. .
