Because the number of the differential pressure adjusting flow channel pair interface 219 is one, the differential pressure adjusting flow channels 212 respectively communicated with the differential pressure control unit output port 217 need to be communicated with the differential pressure adjusting flow channel pair interface 219 after being combined into one. In some embodiments, defining one of the differential pressure regulating flow passages 212 includes a fourth transversely extending bore 2121, a fourth vertically extending bore 2122, and a fourth port input bore 2123 connected in series, the fourth transversely extending bore 2121 extending horizontally toward the mounting side i at the upper end of the body.

The 2 atomizing nozzle air supply switching valves 220 are defined as a first switching valve and a second switching valve, respectively. The atomizing air supply channel 350 connected to the atomizing nozzle air supply channel 211 controlled by the first switch valve supplies air to only one nozzle 320 of the three nozzles 320, and the atomizing air supply channel 350 connected to the atomizing nozzle air supply channel 211 controlled by the second switch valve supplies air to two nozzles 320 of the three nozzles 320 at the same time.

When the first and second on-off valves are all opened, 3 nozzles 320 are simultaneously operated to meet the requirement of a large amount of oil mist. When only a small amount of oil mist is needed, the first switch valve is opened, the second control valve is closed, and one of the nozzles 320 is controlled to work. When the required oil mist amount is between the two conditions, the first switch valve is closed, the second switch valve is opened, and the two nozzles 320 are controlled to work.
