Drainage device and bathroom equipment
The invention relates to a drainage device and bathroom equipment. The drainage device comprises a flushing mechanism, a first control valve, an overflow valve and a second control valve. The flushing mechanism is provided with a driving cavity with variable space size and a driven cavity with variable space size; when the space of the driving cavity is expanded, the driving cavity enables the driven cavity to be compressed through transmission, the space becomes small, and the space variation of the driven cavity is larger than that of the driving cavity. The first control valve has a through-flow state enabling the liquid injection flow channel of the driving cavity to be opened and a cut-off state enabling the liquid injection flow channel of the driving cavity to be closed. The overflow valve is connected between the driving cavity and the driven cavity and used for isolating the driven cavity from the driving cavity in the through-flow state and communicating the driven cavity with the driving cavity in the cut-off state. And the second control valve is used for controlling the on-off of the liquid supplementing flow channel of the driven cavity according to the liquid level height in the driven cavity. After the driven cavity completes fluid supplement, the drainage device can conduct next drainage operation, and circulating operation of the drainage device is achieved.
本发明涉及一种排水装置及卫浴设备，排水装置包括冲水机构、第一控制阀、溢流阀及第二控制阀。冲水机构具有空间大小可变的驱动腔及空间大小可变的从动腔；驱动腔的空间扩张时，驱动腔通过传动使从动腔受压缩而空间变小，从动腔的空间变化量大于驱动腔的空间变化量。第一控制阀具有使驱动腔的注液流道开通的通流状态及使驱动腔的注液流道关断的断流状态。溢流阀连接在驱动腔与从动腔之间，用于在通流状态时使从动腔与驱动腔隔离以及在断流状态时使从动腔与驱动腔连通。第二控制阀用于根据从动腔内的液位高度而控制从动腔的补液流道的通断。在从动腔完成流体的补充后，排水装置即可进行下一次的排水操作，实现排水装置的循环运行。
