▎ 摘　　要

NOVELTY - The mask has a mask body (10) formed with multi nano-sized micro-holes. A filter removal groove (11) is formed on a side of the mask body, and a filter case is detachably attached to a filter detachable groove. An inlet is formed on an inside of the filter case, and an outlet is formed at an outer side of a filter unit to discharge introduced air. The filter case comprises a light weight bio-ball for stably supporting the filter unit, where the bio ball is made of ceramic powder, diatomaceous earth, polycarbonate resin, zeolite, sericite, titanium dioxide, sulfur trioxide and carbomer. The mask body is made of graphene synthetic transparent silicon material. USE - Transparent nano air circulation ventilation structure integrated filter-removable functional mask. ADVANTAGE - The mask can be easily cleaned and used by forming a removable structure in which a filter can be replaced, so that convenience of breathing and effect of blocking droplets through a nano-sized air circulation structure can be maximized, thus improving antibacterial properties and wear stability by being made of silicon material of graphene synthesis. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the transparent nano air circulation ventilation structure integrated filter-removable functional mask (Drawing includes non-English language text).
