The present invention relates to a device for sterilizing and charging a portable terminal using a photocatalyst. The present invention relates to technology in which a protection film mixed with the photocatalyst is attached to a liquid crystal display (LCD) screen of a smartphone and a structure of a charging device is improved to promote a chemical reaction of the photocatalyst with an ultraviolet ray while the smartphone is charged such that active sterilization of a surface of the LCD screen is additionally performed during a charging process and the abrasion level of a photocatalyst layer formed on a surface of the protection film is checked through the ultraviolet ray. According to the present invention, the ultraviolet ray is irradiated during the charging process such that a charging function and a sterilization function by the ultraviolet ray can be simultaneously provided and activation of the chemical reaction of the photocatalyst can be promoted in the protection film by the ultraviolet ray irradiated during charging, thereby maximizing a sterilization effect due to the ultraviolet ray and the photocatalyst during charging. Moreover, when the photocatalyst layer of the protection film is worn by repetitive use, a reflective color is changed during an ultraviolet ray reflection process in accordance with thickness such that a user can easily check whether the protection film is in a degraded sterilization function state, thereby enabling the user to recognize a replacement time of the protection film.COPYRIGHT KIPO 2020본 발명은 광촉매를 활용한 휴대단말기의 충전 살균장치에 관한 것으로,본 발명은 광촉매가 혼합된 보호필름이 스마트폰 액정화면에 부착된 상태에서, 충전장치의 구조를 개선하여 스마트폰이 충전되는 과정에서 자외선을 사용해 광촉매의 화학반응을 촉진시켜 충전과정에서 보다 활발한 액정화면 표면의 살균이 추가적으로 진행되도록 하며, 자외선을 통해 보호필름 표면의 광촉매층 마모정도를 확인할 수 있도록 한 기술이다.본 발명에 의하면,또한, 본 발명에 따른 스마트폰 충전장치에 의하면, 충전과정에서 자외선이 조사됨에 따라 기본적으로 충전기능과 자외선에 의한 살균기능을 동시에 발휘할 수 있을 뿐만 아니라,충전 중 조사되는 자외선에 의해 보호필름 광촉매의 화학반응이 더욱 활발하게 이루어지도록 유도할 수 있기 때문에, 충전하는 동안 자외선 및 광촉매에 의한 살균효과를 최대화시킬 수 있게 된다.
