Drainage structure and vehicle

Abstract

The application discloses a drainage structure and a vehicle. The drainage structure comprises a drainage pipe, an on-off valve, a water flow sensor and a control device. The drainage pipe has an inlet end and an outlet end. The on-off valve is connected with the drainage pipe and is used for conducting and closing the drainage pipe. The water flow sensor is used for detecting the water flow size in the drainage pipe. The control device is electrically connected with the detection device and the on-off valve and is used for controlling the on-off valve to work according to the detection device. At the drainage port needing to be drained, the inlet end of the drainage pipe is communicated. When the water flow sensor detects that there is water flow passing through, the control device controls the on-off valve to open, so that the waste water can be discharged from the outlet end of the drainage pipe. When the water flow sensor detects that there is no water flow passing through, the control device controls the on-off valve to close, so that the harmful gas, impurities and dust outside or the backflow water of the drainage pipe cannot flow back into the vehicle from the outlet end of the drainage pipe, the air tightness of the vehicle is ensured, and the drainage structure with smooth drainage and small risk of water and dust accumulation is provided.
