Rotary drainer

The invention relates to a rotary drainer which is formed by assembling a fixed assembly and a rotary assembly. The fixed assembly sleeves the rotary assembly and comprises a fixed bracket, a positioning hole formed in the center of the fixed bracket and water guide holes formed in the fixed bracket; the rotary assembly comprises a rotary cover, a rotary handle and a rotary shaft, the rotary coversleeves the rotary shaft and is composed of a fixing ring and a water-proof membrane with water guide holes, and the rotary handle sleeves the top of the rotary shaft. Compared with the prior art, the rotary drainer is simple in structure and easy to produce, install, detach and replace; by changing the overlapping area of the water guide holes in the fixed bracket and the water guide holes in the rotary cover, multi-gear drainage can be realized. 本发明涉及种转动式下水器，由固定组件及转动组件组装而成，固定组件套设在转动组件上，包括固定支架、设置在固定支架中心的定位孔以及设置在固定支架内的导水孔，转动组件包括转动盖、转动柄及转动轴，转动盖套设在转动轴上，转动盖由固定圈和开设有导水孔的隔水膜组成。转动柄套设在转动轴的顶部。与现有技术相比，本发明结构简单，易于生产、安装、拆卸和更换；改变固
