It is known that the counterweight ring 11, when far away from the main shaft 6, increases the caliber of the smaller end of the nozzle 9; the counterweight ring 11 reduces the diameter of the smaller end of the nozzle 9 as it approaches the main shaft 6.
It is also known that the mist droplets are ejected from the smaller end of the nozzle 9, the initial velocity of the mist droplets is in positive correlation with the centrifugal force applied to the mist droplets, the centrifugal force applied to the mist droplets is in positive correlation with the rotation speed of the base 5,
inversely related to the orifice diameter of the smaller end of the nozzle 9.

when the base 5 rotates at a lower speed, the counterweight ring 11 approaches the main shaft 6 and reduces the caliber of the smaller end of the nozzle 9 to increase the horizontal initial velocity of the mist droplets.
