[0026] In a specific implementation manner, by setting a slide rod 707, the slide seat 709 is made more stable when moving, and the support of the slide rod 707 prevents the spring 708 from bending when compressed, thereby preventing the bent spring 708 from affecting the rebound effect of the spring 708. By setting a transmission fan 701, the nozzle 5 does not require an additional power source, thereby improving the convenience of use.

[0027] An adjusting plate 10 is connected to the inner wall of the spraying body 4, and a sealing nut is embedded on one side of the spraying body 4, and a threaded rod 9 is connected to the inner thread of the sealing nut, and a knob 3 is connected to one end of the threaded rod 9, and an adjusting block 8 is connected to the other end of the threaded rod 9, the maximum outer diameter of the adjusting block 8 is smaller than the inner diameter of the spraying body 4, and the cross-section of the adjusting block 8 is trapezoidal, the outer wall of the spraying body 4 is respectively connected to a first external tube 1 and a second external tube 2, and the second external tube 2 is located on one side of the adjusting plate 10, and the first external tube 1 is located on the other side of the adjusting plate 10.

[0029] Working principle: When in use, air is blown in through the second external tube 2, and then the raw material in the first external tube 1 is sucked in through the atomizing plate 6 for atomization and spraying on the object to be sprayed. At the same time, the airflow drives the transmission fan 701 to rotate, and then the transmission fan 701 drives the rotating rod 705 to rotate, and the rotating rod 705 drives the knocking bar 703 to rotate. When the knocking bar 703 contacts the stop block 704, the knocking bar 703 moves inward through extrusion and squeezes the spring 708. Then, when the stop block 704 and the knocking bar 703 are misaligned, the sliding sleeve seat 709 drives the knocking bar 703 to hit the atomizing plate 6 through the rebound force of the spring 708, thereby preventing the atomizing plate 6 from being blocked and affecting the spraying effect. Then, by turning the knob 3, the knob 3 drives the adjusting block 8 to move through the threaded rod 9, so that the gap between the adjusting block 8 and the adjusting plate 10 can be adjusted, thereby adjusting the air intake, so that the device can adjust the spraying thickness as needed.
