In the past, the conventional fan nozzle is fixed in the angle of the chamfer due to the physical structure of the fan nozzle when in operation. Therefore, the atomization degree of liquid drops is different due to frequent change of pipeline pressure, when the pressure is increased, the mist cone angle is increased, when the pressure is reduced, the mist cone angle change can influence the spray quality, and uneven mist drop distribution is caused. It is therefore highly desirable to produce a cone angle adaptive atomizing fan nozzle based on a precision variable spray system.

The stable atomization adjusting flow channel is arranged at the joint of the second-stage cylindrical flow channel and the inner nozzle body, the two stable atomization adjusting flow channels are symmetrically distributed on the circumference of the whole nozzle, one end of the push rod is contacted with the tail part of the stable atomization adjusting flow channel, the other end of the push rod is hinged with the rigid adjusting ball body, the rigid adjusting ball body is embedded between the nozzle head and the outer nozzle body, the push rod and the rigid adjusting ball body are driven to reciprocate in a plane under the action of liquid pressure in the stable atomization adjusting flow channel, the nozzle head is made of elastic materials, and swing can be realized under the interaction of the rigid adjusting ball body and the inner nozzle body, so that the size self-adjustment of the cutting groove angle is realized.
