DETAILED DESCRIPTION

[0020] Please refer to Figures 1-4The utility model provides an atomizing device of a liquid spraying gun, which comprises a gun body 1, a box body 2 fixedly connected to the front side of the gun body 1, a water inlet pipe 3 and an atomizing head 4 communicated with the two sides of the gun body 1 respectively, a placing seat 5 fixedly connected to the front side of the gun body 1, a rotating motor 6 arranged on the left side of the inner cavity of the box body 2, a straight rod 7 arranged on the rotating shaft of the rotating motor 6, a rotating mechanism 8 fixedly connected to the surface of the straight rod 7, a threaded rod 9 movably connected to the left side of the inner cavity of the box body 2 through a damping bearing, a moving plate 10 threadedly sleeved on the surface of the threaded rod 9, a cylinder 11 and a guard plate 12 movably connected to the two sides of the moving plate 10 through damping bearings respectively, a clamping block 13 fixedly connected to the surface of the straight rod 7, a clamping frame 14 fixedly connected to the inner cavity of the cylinder 11, and an inspection door formed in the top of the box body 2.

[0021] Please refer to Figure 3 , the rotating mechanism 8 comprises a first gear 15 fixedly sleeved on the surface of the straight rod 7, the surface of the threaded rod 9 is connected with an electric push rod 16 through a mounting plate, the output end of the electric push rod 16 is connected with a second gear 17 through bolts, the second gear 17 is movably sleeved on the surface of the threaded rod 9, the surface of the second gear 17 is provided with a sliding groove, and the second gear 17 is movably sleeved on the surface of the threaded rod 9 through the sliding groove and a sliding block. By arranging the electric push rod 16, the relative positions of the first gear 15 and the second gear 17 can be changed, so that the rotation of the straight rod 7 and the threaded rod 9 can be controlled.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 , the rear side of the inner cavity of the box body 2 is fixedly connected with a limiting frame 18. By arranging the moving plate 10 and the limiting frame 18, the guard plate 12 can be driven to move leftward and rightward, so that the surface of the atomizing head 4 can be protected, and liquid misting can be avoided. The rear side of the moving plate 10 extends to the inner cavity of the limiting frame 18 and is movably connected with the limiting frame 18.

[0023] Please refer to Figure 1 and Figure 2 , the top and the bottom of the box body 2 are fixedly connected with supporting legs 19. By arranging the supporting legs 19 and the placing seat 5, the gun body 1 can be stably placed on the ground, and abrasion caused by the contact between the gun body 1 and the ground can be avoided. The number of the supporting legs 19 is four.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the right side of the guard plate 12 penetrates through the box body 2, the front side of the box body 2 is fixedly embedded with an observation window 20. By arranging the observation window 20, the operator can observe the relative positions of the clamping block 13 and the clamping frame 14 and adjust them in time.

[0025] Please refer to Figure 1 , Figure 2 ,Figure 3 And Figure 4 The surface of the threaded rod 9 is fixedly connected with a sliding block. By arranging the sliding block, the second gear 17 can be assisted and limited in position, which is beneficial to the rotation of the threaded rod 9 driven by the second gear 17. The right side of the cylinder 11 is fixedly connected with the guard plate 12. The front side of the cylinder 11 is transparent. The relative position of the clamping block 13 and the clamping frame 14 can be observed by the operator.

[0026] In use, the rotating motor 6 is started by the external controller to drive the straight rod 7 and the first gear 15 to rotate. The first gear 15 drives the second gear 17 engaged therewith to rotate. The second gear 17 drives the threaded rod 9 to rotate, thereby driving the moving plate 10, the cylinder 11 and the guard plate 12 to move leftward. The clamping block 13 is separated from the clamping frame 14. The guard plate 12 no longer rotates and is thus away from the atomizing head 4 and is accommodated beside the box body 2, avoiding the influence of the spray of the guard plate 12 on the atomizing head 4. The atomizing head 4 is used to spray the atomized liquid. Then the above steps are operated in reverse. The guard plate 12 moves rightward to the right side of the atomizing head 4. The clamping block 13 can be clamped in the clamping frame 14. At this time, the electric push rod 16 is started to drive the second gear 17 to move. The second gear 17 is thus separated from the first gear 15 and no longer engages with the first gear 15. The rotating motor 6 is started by the external controller to drive the straight rod 7 to rotate, thereby driving the clamping block 13 to rotate. Since the clamping block 13 is located in the inner cavity of the clamping frame 14, the clamping block 13 drives the clamping frame 14 and the cylinder 11 to rotate. The cylinder 11 drives the guard plate 12 to rotate until the guard plate 12 rotates to the surface of the atomizing head 4, thereby protecting the atomizing head 4 and preventing liquid from being sprayed by mistake. When the gun body 1 is placed on the ground, the supporting legs 19 and the placing seat 5 are in contact with the ground, thereby stabilizing the gun body 1. At the same time, the gun body 1 is not in contact with the ground, avoiding friction with the ground. The relative position of the clamping block 13 and the clamping frame 14 can be observed through the observation window 20. When the clamping block 13 cannot be directly clamped in the clamping frame 14, the maintenance door is opened for maintenance and adjustment.

[0027] In summary, the atomizing device of the liquid spray gun solves the problems that the conventional atomizing device does not have the advantage of preventing liquid from being sprayed by mistake and the gun body is not stable when placed.
