When in use, the rotating threaded rod 21 drives the cleaning frame 23 to move downward, and when the cleaning frame 23 moves downward, it drives the cleaning brush body 24 to contact the four side surfaces of the printer housing body 20, thereby cleaning the printer housing body 20 from top to bottom. When the cleaning brush body 24 moves to the bottom of one side surface of the printer housing body 20, the threaded rod 21 is reversed to make the cleaning frame 23 move upward, driving the cleaning brush body 24 to clean the printer housing from bottom to top, thereby achieving the effect of cleaning and removing stains on the outer surface of the printer.

[0028] Specifically, refer to Figure 1The top of the processing box 10 is fixedly connected with a motor 25, and the output end of the motor 25 is fixedly connected to the top of the threaded rod 21. When in use, the motor 25 is started by an external power supply, and the output end of the motor 25 drives the threaded rod 21 to rotate.

[0029] The above device can only clean the front, back, left, and right sides of the printer housing body 20, but not the upper and lower sides of the printer housing body 20, so that the cleaning range is not comprehensive. Therefore, a method for cleaning and decontaminating the upper and lower sides of the printer housing is proposed.

[0030] refer to Figure 3-5 , the upper and lower sides of the processing box 10 are rotatably connected with the rotating rod 30, and the rotating rod 30 is fixedly connected with the synchronous pulley 31; the upper and lower sides of the threaded rod 21 are respectively fixedly connected with the same synchronous pulley 31, and the outer side of the pair of synchronous pulleys 31 on the same side is meshed with a conveyor belt 32, and the top of the lower rotating rod 30 is fixedly connected with a first rotating disk 33, and the top of the first rotating disk 33 is fixedly connected with a stain removal brush body 45. When in use, the rotating threaded rod 21 will drive the corresponding synchronous pulley 31 to rotate, and the cooperation of the synchronous pulley 31 and the conveyor belt 32 will drive the two rotating rods 30 to rotate in the same direction, and drive the first rotating disk 33 to rotate in the same direction, so that the stain removal brush body 45 rotates and cleans the bottom surface of the printer housing body 20.

[0031] Specifically, refer to Figure 4 and Figure 5 A fixed plate 40 is fixedly connected to the upper rotating rod 30, a supporting spring 41 is fixedly connected to the bottom of the fixed plate 40, a second rotating disk 42 is fixedly connected to the bottom of the supporting spring 41, a similar stain removing brush body 45 is fixedly connected to the bottom of the second rotating disk 42, a guide groove 43 is provided on the top surface of the second rotating disk 42, the bottom of the upper rotating rod 30 passes through the surface of the second rotating disk 42 and is located inside the guide groove 43; a sliding block 44 is fixedly connected to the bottom of the rotating rod 30, and the sliding block 44 is slidably connected to the guide groove 43.

[0032] Preferably, the guide groove 43 has a hexagonal cross section, and the bottom surface of the sliding block 44 is adapted to the cross section of the guide groove 43 , thereby achieving guidance for the second turntable 42 during movement.

[0033] When the printer housing body 20 is placed on the top surface of the support block 13, it is necessary to lift the second turntable 42 first, and the second turntable 42 slides vertically upward along the surface of the sliding block 44, so that the space between the second turntable 42 and the support block 13 becomes larger, and at the same time drives the support spring 41 to be compressed. After the printer housing body 20 is placed on the top surface of the support block 13, the second turntable 42 is lowered, and the support spring 41 loses its pressure and presses the second turntable 42 on the top surface of the printer housing body 20, so that the stain removal brush body 45 contacts the top surface of the printer housing body 20.
