The invention discloses a drainer which comprises a drain pipe body and a face arranged at a drain opening in the upper end of the drain pipe body. A cavity is formed in a supporting pillar below the face and is internally provided with a spring, and a support extending from the inner cavity of the drain pipe body is sleeved with the spring. The side edge of the supporting pillar extends outwards to form a clamping arm, and the end of the clamping arm is clamped into a lock groove formed in the wall of the inner cavity of the drain pipe body in the state that the face closes the drain opening. The lock groove is communicated with a lock cavity formed in the wall of the inner cavity of the drain pipe body. The end of a lock rod in the lock cavity corresponds to the end of the clamping arm, and the other end of the lock rod is exposed out of the upper end face of the drain pipe body. The lock rod is sleeved with a small spring. One end of the small spring abuts against the wall of the lock cavity, and the other end of the small spring abuts against the lock rod. The drainer is novel in structure, a bounce system is achieved by being divided into two systems through the spring and the small spring, the lock rod touches a lock arm to eject the lock arm out of the lock groove, the spring returns to eject the supporting pillar up so as to eject the face open, the whole process is light and free of the heavy feeling, the manufacturing cost is low, and the service life is long.
