[0002] 3D printing, also known as additive manufacturing or rapid prototyping, is a technology that uses digital model files as a basis and employs powdered metals or plastics and other bondable materials to construct objects layer by layer. 3D printing is typically achieved using digital material printers. It is commonly used in mold making and industrial design to create models, and has gradually been applied to the direct manufacturing of some products; parts printed using this technology already exist. This technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction, automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, and other fields.
[0003] After a 3D printer finishes printing a part, a large amount of powder often remains on the surface of the printed part. Most 3D printers on the market do not have a dedicated powder cleaning device, and the powder can only be cleaned manually, which is time-consuming and labor-intensive, causing inconvenience to the staff and reducing the practicality of the 3D printer. Summary of the Invention

[0026] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings.
[0027] Please see Figure 1-4The dust cleaning device for 3D printed parts includes a supporting shell 1, a working shell 2 fixedly connected to the top of the supporting shell 1, a protective inner shell 3 fixedly connected to the bottom of the working shell 2, a pneumatic cylinder 4 fixedly connected inside the supporting shell 1, a lead screw 5 fixedly connected to the inner wall of the protective inner shell 3, a connecting seat 6 fixedly connected to one end of the lead screw 5, a first base 7 fixedly connected to the top of the connecting seat 6, a worktable 8 fixedly connected to the top of the first base 7, a support plate 10 threadedly connected to the outer wall of the lead screw 5, and a work box 11 fixedly connected to the top of the support plate 10. A storage box 12 is fixedly connected to the outer wall of the box 11. A storage box 13 is movably connected to the inner wall of the storage box 12. An air outlet pipe 14 is fixedly connected to the top of the storage box 12. A filter element 16 is fixedly connected to one end of the air outlet pipe 14. A fan body 15 is fixedly connected to the outer wall of the working box 11. An air inlet pipe 17 is fixedly connected to one side of the storage box 12. An air inlet suction head 20 is fixedly connected to one end of the air inlet pipe 17. A second base 21 is fixedly connected to the inner wall of the working box 11. A mounting plate 18 is fixedly connected to the front of the second base 21. A spring 19 is fixedly connected to the top of the mounting plate 18.
[0028] The bottom of the support plate 10 is movably connected to the limit seat 9, and the bottom of the limit seat 9 is fixedly connected to the output end of the pneumatic cylinder 4.
[0029] A handle 22 is fixedly connected to the front of the storage box 13.
[0030] The air inlet of the fan body 15 is fixedly connected to the end of the air outlet pipe 14 away from the filter element 16.
[0031] The end of the spring 19 away from the mounting plate 18 is fixedly connected to the outer wall of the air intake head 20.
[0032] There are two springs 19, and the two springs 19 are symmetrically arranged with the horizontal center line of the air intake head 20 as the axis of symmetry.
[0033] The front of the second base 21 is fixedly connected to the limiting shaft 24, and one end of the limiting shaft 24 is movably connected to the limiting box 23. The inner wall of the limiting box 23 is fixedly connected to the outer wall of the air intake head 20.
[0034] When in use, the blower body 15 operates, causing dust on the printer surface to enter the material storage box 12 through the air inlet pipes 17 and 20. The filter element 16 blocks the dust from entering the blower body 15. The pneumatic cylinder 4 operates, driving the limit seat 9 to move downward, thereby driving the support plate 10 and the work box 11 to move downward. Because the outer wall of the support plate 10 is threadedly connected to the lead screw 5, the support plate 10 will rotate during the downward movement, causing the air inlet suction head 20 to rotate and move downward along with the work box 11. During the movement of the air inlet suction head 20, it will shake. Due to the setting of the spring 19, the shaking of the air inlet suction head 20 is amplified, allowing the air inlet suction head 20 to more thoroughly clean the dust from the printed parts.
