The nozzle 40 includes a first nozzle 41 and a second nozzle 42, the first nozzle 41 being connected to the first water outlet 31, and the second nozzle 42 being connected to the second water container 20.

Specifically, as shown in fig. 1, the first kettle 10 and the second kettle 20 are independent from each other, and both the first kettle 10 and the second kettle 20 are liquid storage devices for storing washing liquid.

It will be appreciated that in the embodiments of the present disclosure, the first kettle 10 is the primary kettle of the present system and the second kettle 20 is the secondary kettle of the present system. Wherein the first kettle 10 may be a self-contained wash kettle in a vehicle.

The first kettle 10 is communicated with a bidirectional water pump 30, and the bidirectional water pump 30 is provided with a first water outlet 31 and a second water outlet 32. I.e. the two-way pump 30, may create different flow directions for the washing liquid in the first kettle 10.
