This invention relates to an intestinal tract cleaning device of preventive medicine, comprising a storage tank, a negative potential generator, a liquid delivery component, an ejection component, and a control component. The negative potential generator is disposed in the receiving space of the storage tank for switching the potential of liquid to a negative value. The ejection component comprises at its terminal an ejection hole for insertion into a human anus. The control component is disposed between the liquid delivery component and the ejection component to control the timing of spraying the liquid delivered by the liquid delivery component from the ejection hole, thereby providing the effects of energy healthcare and cleaning of human intestinal tract.本發明係有關於一種預防醫學的腸道潔淨裝置,其包括儲槽、負電位發生器、液體輸送組件、噴出組件及控制組件。負電位發生器設於在儲槽之容置空間內,用以使液體的電位轉為負值。噴出組件末端具有供插入人體肛門的噴孔。控制組件設於液體輸送組件與噴出組件之間,以控制液體輸送組件所輸送之液體由噴孔噴出的時機,俾能達到人體腸道的能量保健與洗滌潔淨功效。10‧‧‧儲槽11‧‧‧環緣110‧‧‧開口12‧‧‧輸出口30a‧‧‧能量發生器30b‧‧‧負電位發生器30‧‧‧第一殼體31‧‧‧第二殼體32‧‧‧透孔40‧‧‧液體輸送組件41‧‧‧加壓裝置42‧‧‧管路410‧‧‧本體411‧‧‧連桿412‧‧‧活塞413‧‧‧貫孔414‧‧‧穿孔415‧‧‧閥片416‧‧‧凸體417‧‧‧卡緣418‧‧‧握把50‧‧‧控制組件51‧‧‧壓桿52‧‧‧按壓閥60‧‧‧噴出組件61‧‧‧噴孔62‧‧‧接管63‧‧‧噴管
