Abstract: A drainage assembly and a sink are provided. The drainage assembly includes a base body. Two ends of the base body are provided with an input port and an output port respectively. The input port is communicated with the output port by a flow channel located in the base body. The flow channel includes an upper chamber communicated with the input port and a lower chamber communicated with the output port. The base body is provided with a switch mechanism configured to control connection and disconnection between the upper chamber and the lower chamber. The base body is provided with a water inlet connector and a liquid level measurement connector that are separately communicated with the upper chamber. The drainage assembly and the sink have liquid level measurement and water supply functions in addition to a drainage function.
