Abstract
Abstract A tea brewing apparatus comprising an upper container for simmering tea therein and a lower container for storing the tea brewed in the upper container. The bottom face of the upper container is provided with a tea dripping hole for allowing tea which was brewed in the upper container to flow into the lower container. A ball-activated sieve with an arched stem is disposed in the upper container and above the dripping holes so as to prevent tea leaves from dropping into the lower container. A steel ball disposed inside the sieve is attached to a distal end of a steel wire encompassed by the stem so that the steel ball seals the dripping hole when it is positioned on the dripping hole. A suspending element is attached to the other distal end of the steel wire outside the upper container so as to remotely control the movements of the sealing ball.
