The working principle is as follows: when the electrostatic spray gun capable of dispersing paint particles for automobile coating is used, as shown in fig. 1-6, firstly, an external compressed air source is connected to the outer surface of an air inlet joint 20, then an external paint body conveying device is connected to the outer surface of a paint spray pipe 22, at the moment, a clamping rod 15 slides and compresses a supporting spring 16, an adjusting wheel 2 is rotated to enable an extrusion block 3 to extrude an ejector rod 10, the ejector rod 10 stretches a return spring 11 and drives a filter ring 12 to slide between a feeding pipe 18 and a material guide pipe 19, then the clamping rod 15 is released, the clamping rod 15 is clamped with a clamping block 4 under the driving of the compressed supporting spring 16, due to the existence of an avoidance groove 6 preset on the outer surface of the sliding ring 5, the sliding ring 5 can slide and rotate a cover plate 9, the sliding ring 5 compresses the supporting spring 16 through the clamping rod 15, so that when the clamping rod 15 is released, the limiting rod 7 fixed on the outer surface of the sliding ring 5 pushed by the compressed support spring 16 is clamped, so that the discharge hole 8 cannot be blocked by the cover plate 9 and cannot be discharged;
as shown in fig. 1-9, at this time, the rotating rod 23 is rotated, the rotating rod 23 drives the driven gear 25 to rotate through the driving gear 24, the driven gear 25 drives the sliding plate 27 to rotate through the rotating block 26, the sliding plate 27 drives the displacement rod 28 to rotate, the displacement rod 28 rotates and drives the discharging block 29 to move through the threaded connection with the gun body 1, so that the mixture of the paint and the compressed air respectively sprayed from the air nozzle 21 and the paint spray pipe 22 in the gun body 1 can enter the feeding pipe 18 through the gap between the discharging block 29 and the feeding pipe 18 after the movement of the discharging block 29, the spraying speed of the spray gun is adjusted by continuously rotating the rotating rod 23 to adjust the gap between the discharging block 29 and the feeding pipe 18, the spraying is effectively controlled, meanwhile, the filter rings 12 with different filtering precisions are moved to the positions between the feeding pipe 18 and the feeding pipe 19 through the adjusting wheel 2, so that, the aim of dispersing large-particle paint particles and small-particle paint particles is fulfilled;

as shown in fig. 1 and 6, when an operator forgets to rotate the adjusting wheel 2 before spraying, so that the filter ring 12 moves between the feeding pipe 18 and the material guiding pipe 19 and the cover plate 9 is opened, because the adjusting wheel 2 is not rotated, the position of the sliding ring 5 facing the clamping rod 15 does not avoid the existence of the groove 6, so that the clamping rod 15 extrudes the sliding ring 5 under the support of the supporting spring 16, the sliding ring 5 extrudes the cover plate 9 through the limiting rod 7, so that the cover plate 9 keeps the sealing of the discharge hole 8, and the condition that paint particles with different sizes exist on the paint surface due to the fact that paint which is not filtered is sprayed on an automobile covering part is avoided;
after the spraying is finished, as shown in fig. 1-4, water is injected into the gun body 1 through the paint spraying pipe 22, the water is driven by compressed air to enter a cavity with large-particle paint particles in the gun body 1, the paint particles are dissolved in the water and flow out of the gun body 1 along with water flow after the liquid outlet 17 is opened, so that the residual paint in the gun body 1 is recovered while the inside of the gun body 1 is cleaned, and the waste of the paint and the mixed color of the paint are avoided.
