[0026] In the application, the first filter structure includes a spiral flow guide plate, and the spiral flow guide plate is used for guiding the smoke dust entering the cyclone filter powder bucket 1 to make spiral motion and separating large particles in the smoke dust.

[0027] In the application, the second filter structure 2 includes a filter core 21, and the filter core 21 is used for adsorbing small particles in the smoke dust.

[0028] In one embodiment provided by the application, the 3D printing equipment miniaturized integrated filter device 100 further includes a filter bucket 3, the filter bucket 3 is communicated with the smoke dust outlet, and is used for collecting smoke dust residues after filtration.

[0029] In the application, the 3D printing equipment miniaturized integrated filter device 100 further includes a vibration motor 4, the vibration motor 4 is arranged outside the cyclone filter powder bucket 1 and is in contact with the cyclone filter powder bucket 1, and is used for shaking off the smoke dust remaining on the first filter structure and the second filter structure 2.

[0031] In specific implementation: when the 3D printer starts to work to generate smoke dust, the smoke dust is guided into the cyclone filter powder bucket 1 through the copper wire hose. In the cyclone filter powder bucket 1, the smoke dust makes spiral motion under the action of the spiral flow guide plate, and large particle smoke dust is thrown to the barrel wall and settles due to the centrifugal force, and primary filtration is completed; the smoke dust after primary filtration continues to move upwards and passes through the filter core 21. The coarse filter layer of the filter core 21 first intercepts small particles with a larger particle size, and then the fine filter layer adsorbs small particles, so that secondary filtration is realized. The residues after twice filtration naturally settle to the bottom of the cyclone filter powder bucket 1 by gravity; when the residues need to be recovered, the control butterfly valve 5 is opened, and the residues fall into the filter bucket 3 under the action of gravity. In the long-term use process, the timing controller starts the vibration motor 4 according to the set time and frequency, the vibration generated by the vibration motor 4 is transmitted to the filter core 21, so that the residues adsorbed on the filter core 21 are shaken off, thereby maintaining the filtration performance of the filter core 21.

[0032] From the structure and specific implementation process of the small-sized integrated filter device 100 by the 3D printing equipment, it can be known that by integrating multiple filtering functions in a smaller space, the equipment size is effectively compressed, which is particularly suitable for small-sized 3D printers, solves the problem of large size of traditional filter devices, reduces the use of connecting pipelines, and small-sized design reduces material cost and installation cost, so that the overall cost of the 3D printer is effectively controlled; the combination of the preliminary filtering of the cyclone powder filtering barrel 1 and the secondary filtering of the filter core 21 can comprehensively filter large particles and small particles in the printing smoke dust, improve the filtering efficiency and quality, and ensure that the discharged gas meets the environmental protection requirements; the detachable structure of the filter barrel 3 and the automatic cleaning function of the vibration motor 4 on the filter core 21 make the equipment more convenient and fast during maintenance, and reduce the maintenance time and cost.

[0033] In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0034] The above is only a specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
