The present invention relates to a watertight unit of a tea maker, and more specifically, to a watertight unit of a tea maker, which pressurizes a valve unit so that water does not leak through a discharge hole when water is supplied to coffee or tea and is brewed to extract effective components of coffee or tea, can control concentration of coffee or tea by selection of a user since time for brewing coffee or tea can be controlled, and maintains water tight by controlling opening of the discharge hole caused by flow of the valve unit when moving by applied pressure caused by elastic force of the watertight unit, thereby preventing leakage of coffee or tea. |
