By changing the size of the channel, the speed and flow of the fluid can be regulated, so that the magnetic powder can be concentrated when sprayed, and the sprayed magnetic powder can be uniformly covered.

[0026] Embodiment 2

[0027] Based on the embodiment 1, the scheme in the embodiment 1 is further refined in combination with the specific working mode as follows: Figures 1 to 4 As shown, details are described below:

[0028] As a preferred embodiment, the flow regulating assembly 9 comprises a shell 901, an adjusting plate 22, a first adjusting hole 13, a second adjusting hole 14 and a third adjusting hole 2201, the adjusting plate 22 is mounted on the inner wall of the shell 901, the first adjusting hole 13 is arranged on the inner wall of the adjusting plate 22, the second adjusting hole 14 is arranged below the first adjusting hole 13, and the third adjusting hole 2201 is arranged on the side of the first adjusting hole 13 away from the second adjusting hole 14. When the flow regulating assembly 9 is used, the position of the adjusting plate 22 in the shell 901 is pressed, the magnet passes through different adjusting holes, and the diameter of the adjusting hole changes the flow of the sprayed magnetic powder.

[0029] As a preferred embodiment, the flow regulating assembly 9 and the center of the spray head 12 are provided with a spray pipe 11, and the spray head 12 and the flow regulating assembly 9 are fixed by a sealing ring 10. At this time, the flow regulating assembly 9 is used to adjust the size of the pipe in the connected spray pipe 11. When the magnet is sprayed through the spray pipe 11, the sealing ring 10 fixes the spray head 12 pipe and the flow regulating assembly 9 during the spraying process, and then the sprayed magnet enters the inside of the spray head 12 pipe through the spray pipe 11, so that the magnetic powder is sprayed through the spray head.

[0030] As a preferred embodiment, triggers 7 are provided on both sides of the switch 6, and a rotating structure is formed between the switch 6 and the trigger 7 through a docking rod 8. When the trigger 7 is pressed, the trigger 7 drives the switch 6 to open through the docking rod 8, so that the magnetic powder is sprayed into the jet tube 11 through the spray gun tube 5.

[0031] As a preferred embodiment, a first fixed ring 15 is installed below the spray gun body 1, and a first conveying pipe 17 is installed below the first fixed ring 15, and a storage tank 19 is provided on the side of the first conveying pipe 17 away from the first fixed ring 15, and the spray gun body 1 and the first conveying pipe 17 are connected through the first fixed ring 15, and the magnetic powder is placed inside the storage tank 19, so that the magnetic powder is blown by the internal fan and flows along the first conveying pipe 17.

[0034] The working process of the present invention is as follows: first, when the spray gun body 1 is in use, the fan inside the storage tank 19 agitates the magnetic powder to be transported along the first conveying pipe 17, and the magnetic powder enters the spray gun tube 5 through the first conveying pipe 17. At this time, the air pump conveys through the second conveying pipe 18, so that the air flow enters the interior of the spray gun tube 5 through the second conveying pipe 18, so that the magnetic powder is driven by the air flow and enters the interior of the jet pipe 11 through the jet pipe. Then, the flow regulating component 9 adjusts the jet pipe 11 so that the magnetic powder The powder is regulated by the flow regulating component 9, and the magnetic powder enters the inside of the nozzle 12 through the jet pipe 11, so that the magnetic powder is sprayed out through the nozzle 12, and then the lighting lamp 20 inside the lighting bracket 4 is turned on, so that the lighting lamp 20 illuminates the sprayed magnetic powder and displays the adhesion traces of the magnetic powder. Then, when the transparent cover 21 affects the illumination of the lighting lamp 20, the transparent cover 21 is replaced at this time to facilitate the restoration of the illumination of the lighting lamp 20. The above is the working principle of the magnetic powder spray gun that sprays evenly.

[0035] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
