Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Referring to Fig. 1-3, the present embodiment includes atomizer 1, control valve 2 and parting compound spray head 3, atomizer 1,2 He of control valve
Parting compound spray head 3 flows through pipeline by parting compound and is sequentially connected；Atomizer 1 includes the gas being arranged in nebulizer body shell
The center line of liquid hybrid channel 1-1 and liquid feeding channel 1-2, gas-liquid mixed channel 1-1 be straight line, left side port be high pressure gas into
Mouth 1-1-1, middle part are equipped with throttle orifice 1-1-2, and right side port is parting compound mist state outlet 1-1-3, one end of liquid feeding channel
Mouth is parting compound import 1-2-1, and another port passes through the throttle orifice 1- in the middle part of conduction hole 1-2-2 and gas-liquid mixed channel 1-1
1-2 connection；The parting compound mist state outlet (1-1-3) of atomizer is connected to by control valve 2 with the arrival end of parting compound spray head 3.
Liquid feeding channel 1-2 is located at the top of gas-liquid mixed channel 1-1 comprising for sap cavity, for sap cavity top pass through it is close
Capping 1-2-3 thread seal connects to form liquid feeding channel 1-2, and parting compound import 1-2-1 is arranged on the side wall for sap cavity, feed flow
The bottom of chamber is threadedly coupled with core 1-2-4 is mended, and is equipped with through-hole in the axle center for mending core 1-2-4, through-hole is the conduction hole of liquid feeding channel
1-2-2。
