[0037] Reference Figure 3-Figure 4 , which is basically the same as Example 1, and further, a specific implementation scheme of spraying powders of different sizes as needed is added.

[0038] Due to improper storage methods, some powders tend to clump during storage.

During use, powder that meets the requirements enters the powder outlet pipe 201, ensuring the quality of spraying.

[0039] Since the powder sizes used for spraying are different in different spraying processes, the prior art often uses devices that match a variety of powder sizes for spraying, which is cumbersome to operate, has high equipment costs, and occupies a large space. Figure 3-Figure 4 A second filter hole 205 and a third filter hole 206 are provided at the bottom of the filter barrel 203, and the number of the second guide platform 2, the powder outlet pipe 201, and the first air outlet pipe 108 are all three.

[0040] The area formed between the first filter hole 204 and the partition plate 207 is the first chamber, the area formed between the second filter hole 205 and the partition plate 207 is the second chamber, and the area formed between the third filter hole 206 and the partition plate 207 is the third chamber.

[0041] In this embodiment, there are three feed control mechanisms. When a certain size of powder is needed, the powder is poured from the powder feed hopper 7 into the corresponding first chamber, second chamber or third chamber, and then the spraying equipment is connected to the corresponding powder outlet pipe 201. This allows the use of powders of various sizes, reduces the cost of purchasing different types of devices, reduces occupied space, and facilitates use.

[0042] Embodiment 3:

[0043] Reference Figure 5-Figure 6 , which is basically the same as Example 2, and further, a specific implementation scheme for reducing the clogging phenomenon of the filter barrel 203 is added.

[0045] In this embodiment, one feeding control mechanism is used, and the feeding control mechanism corresponds to the first chamber, that is, the powder feeding hopper 7 is communicated with the first chamber.

[0047] It should be additionally explained that a sprocket is fixedly connected to the outer wall of the third rotating rod 307 and the second rotating rod 306 , and the chain 309 is drivingly connected to the sprocket.

[0048] The partition plate 207 drives the third rotating rod 307 and the second rotating rod 306 to revolve around the first rotating rod 301. At the same time, the first gear 303 drives the second gear 308 to rotate, so that the second rotating rod 306 rotates. Under the transmission action of the chain 309, the second rotating rod 306 drives the turntable 4 to rotate, and the turntable 4 drives the soft bristles 401 to rotate, thereby facilitating the reduction of blockage in the filter barrel 203.

[0049] Since the powder moves toward the second guide platform 2 under the action of the airflow, some of the powder easily flows into the adjacent chamber from the first groove 304, thereby affecting the use effect. Figure 5 A guide plate 402 is fixedly connected to the surface of the partition plate 207, a connecting plate 403 is fixedly connected to the side wall of the guide plate 402, a second groove 305 is opened on the surfaces of the connecting plate 403 and the guide plate 402, the second groove 305 is interconnected with the first groove 304, the first gear 303 is located in the second groove 305, and the guide plate 402 can block part of the powder from entering the adjacent chamber from the first groove 304, and the second groove 305 is set to facilitate the first gear 303 and the second gear 308 to mesh with each other.

The second threaded hole 503 matches the first threaded hole 502. The first threaded hole 502 is internally threadedly connected with a first bolt 504. A third air outlet pipe 5 is fixedly connected to the surface of the cover plate 202. The third air outlet pipe 5 corresponds to the first air outlet pipe 108 one by one.

[0053] After cleaning the partition plate 207 and the soft bristles 401, place the partition plate 207 in the filter barrel 203, align the second threaded hole 503 with the first threaded hole 502, and screw the first bolt 504 into the first threaded hole 502 to fix the position of the cover plate 202. The first air outlet pipe 108 can quickly locate the position of the third air outlet pipe 5. Before docking, the upper surface of the docking joint 501 is flush with the upper end of the first air outlet pipe 108. After placing the third air outlet pipe 5 on the surface of the first air outlet pipe 108, rotate the docking joint 501 so that the docking joint 501 is clamped between the first air outlet pipe 108 and the third air outlet pipe 5, thereby realizing the installation between the first air outlet pipe 108 and the third air outlet pipe 5, thereby facilitating regular cleaning of the partition plate 207 and the soft bristles 401 and improving the spraying effect.
