Abstract: The present invention is a multi-functional thermos mug having bamboo charcoal. The thermos mug comprises a lid provided therein with an inner thermos cover made from bamboo charcoal ceramics and a cup shell provided therein with an inner thermos cup body made from bamboo charcoal ceramics. The inner thermos cover and inner thermos cup body could deodorize foul smell and emit far infrared. The inner thermos cover body and the inner thermos cup body are manufactured from injection molding a powder and another plastic powder. The powder is obtained from burning a bamboo charcoal or far infrared mineral together with an anion mineral. Positioning means are provided between the components of the thermos mug such that the lid, inner thermos cover body, outer cup shell, inner thermos cup body and base cannot rotate with respect to each other or slip up and down when they are combined together. Consequently, the assembled thermos mug is multi-functional and with a great stability.
