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.

Abstract: An aeration plate is provided, including an aeration top plate portion and a side baffle portion. The aeration top plate portion is scattered with a plurality of aeration holes, such that the aeration top plate portion and the side baffle portion cooperate to form an aeration member. A fruit and vegetable cleaning machine is provided, including a machine body. The machine body is provided with a cleaning tank with a top opening, and the cleaning tank is provided with the aeration plate at an inner bottom wall, such that an area enclosed by the aeration top plate portion, the side baffle portion, and the inner bottom wall forms a first dissolving zone for gas and water, and a second dissolving zone for bubbles and water is formed between a periphery of the aeration plate and the cleaning tank.
