[0002] The existing announcement number is CN 217085518 U. A laser printer waste powder bin is provided. The waste powder bin body is moved out of the printer, and then the fastening bolt is turned to disconnect the connection block from the surface of the waste powder bin body, and the baffle is opened to dump the waste powder to the outside through the powder outlet. Then, the threaded column is driven to rotate by turning the knob, thereby driving the threaded sleeve, the connecting column and the scraper to move, and the waste powder remaining on the inner wall of the waste powder bin body is discharged from the powder outlet, thereby completing the cleaning. In actual use, the waste powder falls into the waste powder bin from the powder inlet and can only be accumulated at the lower side of the powder inlet, which is likely to cause the powder inlet area of ​​the waste powder bin to be reduced in the long term, affecting the effect of waste powder entry.
