By starting the vacuum pump 212, air enters the dust collection box 205 through the arc tube 206, and then enters the air suction pipe 214 from the dust collection box 205, and then enters the collecting box 211 from the air suction pipe 214, and then is discharged into the air suction pipe 213, and finally is discharged from the output end of the vacuum pump 212.

[0027] Among them, the vacuum pump 212 adopts the KVP300-KJ (24V) of the kamoer brand.

[0028] Reference Figure 1 and Figure 2 The telescopic end of the electric telescopic rod 201 is installed with a support plate 202, and the dust box 205 is set on the support plate 202. By starting the electric telescopic rod 201, its telescopic end drives the movement of the support plate 202, and the movement of the support plate 202 drives the movement of the dust box 205, thereby driving the movement of the arc tube 206.

[0029] Reference Figure 4A U-shaped plate 207 is installed at the bottom of the arc tube 206, and a motor 208 is installed on the U-shaped plate 207. The output end of the motor 208 passes through one side of the U-shaped plate 207 and is installed with a shaft 209. A brush 210 is installed on the outer side of the shaft 209. By starting the motor 208, it drives the shaft 209 to rotate, and the rotation of the shaft 209 drives the rotation of the brush 210, thereby achieving the effect of rubbing and scraping off the residue attached to the printing area.

The mounting frame 304 is connected to the annular plate 306. The second spring 307 and the annular plate 306 are used to support the mounting plate 303, which helps to reduce the force on the annular rubber sheet 302.

[0034] Working principle:

[0035] The 3D printer printing area slag removal device starts the motor 208 to drive the shaft 209 to rotate, and the rotation of the shaft 209 drives the brush 210 to rotate. By starting the vacuum pump 212, air passes through the arc tube 206 and enters the dust box 205, and then enters the suction pipe 214 from the dust box 205, and then enters the collection box 211 from the suction pipe 214, and then is discharged into the suction pipe 213, and finally discharged from the output end of the vacuum pump 212. At the same time, the electric telescopic rod 201 is started to drive the arc tube 206 to move, thereby achieving the effect of frictionally scraping off the residue attached to the printing area, which helps to suck the residue into the collection box 211 along with the air, and achieves the effect of slag removal.

[0036] The 3D printer printing area deslagging device can start the vibration motor 305 to vibrate the filter 215 when the vacuum pump 212 is not working, which helps to shake off the residue attached to the filter 215 and avoid the filter 215 being blocked to affect the deslagging ability.
