[0038] The cleaning nozzle 1 is closer to the fluid outlet end 31 of the spray bar 3 than the blowing nozzle 2, so that the cleaning agent sprayed by the cleaning nozzle 1 can thoroughly clean the spray bar 3 with the help of the airflow from the blowing nozzle 2. Furthermore, the blowing nozzle 2 ensures that the cleaning agent cleans forward (i.e. towards the end of the spray bar 3 with the fluid outlet end 31) during cleaning, preventing the cleaning agent from overflowing from the rear end and contaminating other areas.

[0039] The blower nozzle 2 has an air inlet chamber 21, an air inlet 22 connected to the air inlet chamber 21, and at least one air outlet 23.

With this configuration, a portion of the cleaning agent in the mixing chamber 12 is directly ejected from the nozzle 13, while the remainder flows to the closed end and then flows back to the nozzle 13 to collide with new cleaning agent. This causes the cleaning agent to be ejected from the nozzle 13 at various angles, ultimately creating a reciprocating oscillation effect along the length (i.e., left-right) of the mixing chamber 12. In other embodiments, multiple nozzles are provided, distributed along the length of the mixing chamber.
