[0032] Please refer to Figure 1 The first steam conduit 20 is provided with a first steam inlet 201, and the first steam inlet 201 is used to receive atomized steam. On the one hand, the atomized steam can dissolve part of the waste liquid in the steam, and on the other hand, the steam can purge the waste liquid spray gun 1000, thereby clearing and cleaning the waste liquid in the waste liquid spray gun 1000. One end of the first steam conduit 20 is the first steam inlet 201, and the other end is connected to the second waste liquid conduit 103.

[0033] Specifically, a second steam purge valve 202 and a third steam purge valve 203 are provided on the first steam conduit 20. The second steam purge valve 202 and the third steam purge valve 203 jointly control the entry of atomizing steam into the waste liquid conduit 10. The second steam purge valve 202 is in a normally open state. When the third steam purge valve 203 fails, the second steam purge valve 202 is used as a backup valve.

[0034] like Figure 1 As shown, the spray gun pipeline 30 includes a cavity conduit 301 and a spray gun head 302. One end of the cavity conduit 301 is connected to the third waste liquid conduit 104 of the waste liquid conduit 10, and the other end of the cavity conduit 301 is connected to the spray gun head 302.
