A liquid cyclone core 3 is fixed in the first round tube, the liquid cyclone core 3 comprises a first column body 7, four first blades 8 are fixed on the outer wall of the first column body 7, and the first blades 8 are obliquely arranged. By arranging the liquid cyclone core 3, the liquid entering the liquid pipeline 2 can be accelerated and rotated to form vortex, a firing pin 6 is also fixed in the nozzle sleeve 1, the firing pin 6 is positioned at the position right in the middle of the nozzle sleeve 1, and the firing pin 6 is aligned with the liquid pipeline 2. The firing pin 6 comprises a second cylinder 9, three second blades 10 are fixed on the outer wall of the second cylinder 9, the cross section of each second blade 10 is rectangular, and the cross section of the second cylinder 9 is circular. By fixing the striker 6 in the nozzle sleeve 1, the liquid moving at high speed collides with the striker 6, so that the liquid is broken into fine droplets to form preliminary atomization.
