본 발명은 0.01∼20 nm 크기의 은 나노 입자들(nano-silver particles)이 함침된 숯 분말이 균일하게 코팅된, 흡수재가 봉(손잡이부)에 부착되어 있는 1회용 흑면봉 및 그 제조 방법에 관한 것이다. The present invention relates to a disposable black cotton swab having an absorbent attached to a rod (knob), which is uniformly coated with charcoal powder impregnated with silver nanoparticles of 0.01 to 20 nm in size, and a method of manufacturing the same. It is about.

종래의 단단한 금속 재질로 된 일체형 귀이개(귀쑤시개)는 귀지를 긁어낼 때 귓속의 민감한 피부를 손상시켜 염증을 유발하고, 심지어 고막을 손상시킬 수 있는 폐단이 있었다. 또한, 나무 또는 플라스틱 재질에 솜 또는 면 등의 흡수재를 부착시킨 종래의 면봉은 항균력, 살균력 등에 한계가 있으며, 이물질들에 대한 흡착성이 떨어지는 문제점이 있었다. Conventional hard metal integral earpicks (earpicks) have a lung lesion that can damage sensitive skin in the ear when scratching earwax, causing inflammation and even damaging the eardrum. In addition, the conventional cotton swab attached to the absorbent material such as cotton or cotton on the wood or plastic material has a limit on antibacterial activity, bactericidal power, etc., there was a problem that the adsorption to foreign matters is poor.

한편, 당업계에서는 귀이개(또는 면봉)의 구조를 다양하게 변형시키거나, 전계 발광 소자(LED) 또는 조명이 부착된 귀이개(또는 면봉)를 제공하여 부주의에 의한 피부 손상 등의 위험을 줄이거나, 소독액이 주입된 면봉 또는 물면봉을 제공하여 편리성을 증진시키려는 노력이 있었으나, 근본적은 해결책은 되지 못하였다. On the other hand, in the art to reduce the risk of inadvertent skin damage by providing various modifications to the structure of the earpick (or cotton swab), or by providing an electroluminescent device (LED) or a lighted earpick (or swab), Efforts have been made to improve convenience by providing swabs or swabs infused with disinfectant solution, but this has not been a fundamental solution.
