Abstract

Disclosed is a water tank drainage volume control structure comprising: a water tank body (1), having a first water storage chamber (11) and a second water storage chamber (12), the first water storage chamber (11) being provided with a first drainage channel, and the second water storage chamber (12) being provided with a second drainage channel; a drainage valve (2), used for controlling the opening/closing of the second drainage channel, the drainage valve (2) being provided with a full-drainage switch and a half-drainage switch for controlling the opening of the second drainage channel; and a water blocking member (3), moving with respect to the water tank body (1) under the control of the full-drainage switch or the half-drainage switch so as to control switching of the first drainage channel between open and closed states. The present invention uses a drainage valve to control drainage, can also achieve half drainage and full drainage of a water tank, and is simple in structure and reliable in function.
