[0029] The specific implementation method is as follows: by setting up the disassembly mechanism 4, by squeezing the buttons 401 on the upper and lower sides to drive the moving block 407 to move, and at the same time compressing the second spring 408, the movement of the moving block 407 will squeeze the clamping block 404, so that the clamping block 404 moves out of the clamping groove 403, and by setting inclined surfaces on both sides of the clamping block 404, the clamping block 404 can be squeezed by one side of the clamping groove 403 when the nozzle 2 moves and further move into the slide groove 406, so that the clamping block 404 can be better separated from the clamping groove 403, and then the nozzle 2 can be quickly removed from the spray gun part body 3, thereby improving the speed of disassembly. When the nozzle 2 is in operation, the clamping block 404 is driven to move, so that the side of the clamping block 404 provided with the inclined surface is squeezed with the inner wall of the spray gun body 3, thereby driving the clamping block 404 to move into the slide groove 406 and driving the first spring 405 to be compressed. When the slide groove 406 is aligned with the clamping groove 403, the first spring 405 releases its elastic force to drive the clamping block 404 to move, so that the clamping block 404 enters the clamping groove 403, thereby clamping with the clamping groove 403, and then the nozzle 2 can be quickly installed on the spray gun body 3, which improves the installation speed, thereby shortening the time required for replacing the nozzle 2, and then improving the work efficiency of replacing the nozzle 2.

[0030] The outer wall of the nozzle 2 is slidably connected with the inner wall of the spray gun body 3, the inner wall of the atomizer cap 1 is provided with a second thread groove 6, the outer wall of the spray gun body 3 is provided with a thread, and the spray gun body 3 is threadedly connected with the second thread groove 6 through the thread, a plurality of vent holes 7 are provided on one side of the nozzle 2, a second groove 11 is provided on one side of the inner wall of the atomizer cap 1, the inner wall of the second groove 11 is fitted with the outer wall of the nozzle 2, a first groove 8 is provided on one side of the second groove 11, and two through grooves 9 are provided on the inner wall of the first groove 8, two gas delivery holes 10 are provided on the outer wall of the atomizer cap 1, one side of the gas delivery hole 10 is connected with one side of the through groove 9, and one side of the atomizer cap 1 is provided with Two adjustment mechanisms 5, the adjustment mechanism 5 includes a fixed block 501, one side of the fixed block 501 is connected to one side of the outer wall of the atomizer cap 1, a ventilation groove 505 is provided on one side of the fixed block 501, and one side of the ventilation groove 505 is connected to one side of the air delivery hole 10, a first thread groove 507 is provided on the other side of the ventilation groove 505, a threaded rod 504 is threadedly connected to the inner wall of the first thread groove 507, and one end of the two threaded rods 504 extends to the outside of the first thread groove 507 and is connected to a knob 503, and the other end of the threaded rod 504 is connected to a rotating block 506, and the inner walls of the two ventilation grooves 505 are provided with two air outlet holes 502.

[0031] The specific implementation method is as follows: by setting an adjustment mechanism 5, the threaded rod 504 is driven to rotate by twisting the knob 503, and the rotation of the threaded rod 504 drives the rotating block 506 to move. By setting the inner wall of the ventilation groove 505 to a curved surface with a certain angle, and the outer wall of the rotating block 506 is parallel to the curved surface at an angle formed by the inner wall of the ventilation groove 505, the rotating block 506 can adjust the size of the gap between the inner wall of the ventilation groove 505 and the outer wall of the rotating block 506 during the movement, thereby changing the flow rate of the compressed gas, so that the force of the compressed gas to break up the paint becomes greater, so that the paint can be dispersed into finer particles, thereby improving the atomization effect, and at the same time achieving the adjustability of the atomization effect, thereby improving the applicability of the nozzle 2, and by setting the air outlet 502 to a certain angle, the compressed gas can drive the atomized paint to spray forward while atomizing the paint.

[0032] Working principle: When in use, the compressed gas will enter the first groove 8 from the vent hole 7, enter the air delivery hole 10 through the through groove 9, then enter the vent groove 505 from the air delivery hole 10, and finally be sprayed out from the air outlet 502, thereby breaking up the paint sprayed from the nozzle 2, thereby achieving the effect of atomization. By twisting the knob 503, the threaded rod 504 is driven to rotate, and the rotating block 506 is driven to move, so that the rotating block 506 adjusts the gap between the inner wall of the vent groove 505 and the outer wall of the rotating block 506, thereby changing the flow rate of the compressed gas, and then adjusting the strength of the compressed gas to break up the paint, so that the paint can be dispersed into particles of different sizes, thereby adjusting the size of the atomization. When the nozzle 2 needs to be disassembled, the buttons 4 on the upper and lower sides are squeezed. 01 drives the moving block 407 to move and squeezes the clamping block 404, so that the clamping block 404 moves out of the clamping groove 403, thereby separating the clamping block 404 from the clamping groove 403, and then the nozzle 2 can be quickly removed from the spray gun part body 3. When installation is required, the clamping block 404 is driven to move by the nozzle 2, so that the side of the clamping block 404 provided with the inclined surface is squeezed with the inner wall of the spray gun part body 3, thereby driving the clamping block 404 to move into the slide groove 406 and compressing the first spring 405. When the slide groove 406 is aligned with the clamping groove 403, the first spring 405 releases the elastic force to drive the clamping block 404 to move into the clamping groove 403, thereby clamping with the clamping groove 403, and then the nozzle 2 can be quickly installed on the spray gun part body 3.
