Abstract

A tea flushing device comprises a cup body, a filtering net, a buckling disk, and a water stopper. The bottom of the cup body is installed with a long hole for being buckled and penetrated by a buckling disk so that the cup body and the buckling disk may move upwards and downwards with respective to one another. Other than protruding from the through hole installed on the buckling disk, in a plurality of foot plates, a water stopper is installed at the through hole of the bottom of the cup body. The water stopper may be a metal rolling ball with a elastic rubber water stop pad or be formed a water stopping block and guide rod. Therefore, as the tea flushing device is flatly placed on a plane, by the supporting of the foot plate, the buckling disk will drop down naturally so that the water stopper will seal the through hole. Thus, the operation of flushing tea within the cup can be performed. If desired, the tea flushing device is only necessary to be placed at a proper container. The buckling disk will be ejected by the container so as to automatically eject the water stopper, and thus the tea water may successful drain to the container. Therefore, it has a simpler structure, and can be operated conveniently so as to have a preferred water stopping effect.
