[0035] The dust cleaning unit 200 includes a U-shaped frame, a first lead screw 220, a second lead screw, a first motor 251, a second motor 252, a first slider 231, a second slider, a connecting rod 240, and a cleaning part 241; wherein, in the various figures, the structures of the second lead screw and the second slider are not shown;

[0036] The square frame is detachably fixed to the back plate 130. The square frame includes a first horizontal square tube 211, a first vertical square tube 212, a second horizontal square tube 213, and a second vertical square tube 214 connected in sequence from end to end. The first horizontal square tube 211, the first vertical square tube 212, the second horizontal square tube 213, and the second vertical square tube 214 are arranged around the circumference of the advertising machine body 140.

[0037] The first lead screw 220 and the second lead screw are respectively disposed in the first horizontal square tube 211 and the second horizontal square tube 213, and the two ends of the first lead screw 220 and the second lead screw are respectively rotatably connected to the two end side walls of the first horizontal square tube 211 and the second horizontal square tube 213.

[0038] The first slider 231 and the second slider are respectively disposed in the cavities of the first transverse square tube 211 and the second transverse square tube 213; the first slider 231 and the second slider are respectively threadedly connected to the first lead screw 220 and the second lead screw;

[0039] The inner sides of the first horizontal square tube 211 and the second horizontal square tube 213 are respectively provided with a first limiting groove 211a and a second limiting groove; the two ends of the connecting rod 240 pass through the first limiting groove 211a and the second limiting groove respectively and are fixedly connected to the first slider 231 and the second slider respectively.

[0040] The cleaning part 241 is fixed on the connecting rod 240; the cleaning part 241 is a rubber scraper, and the lower end of the rubber scraper is attached to the display surface of the advertising machine body 140; the rubber scraper is set along the length of the connecting rod 240;

[0041] The first motor 251 and the second motor 252 are respectively fixed to the ends of the first horizontal square tube 211 and the second horizontal square tube 213; the main shafts of the first motor 251 and the second motor 252 are respectively fixedly connected to one end of the first lead screw 220 and the second lead screw; wherein, the first motor 251 and the second motor 252 are controlled by a controller installed on the advertising machine; after a preset time interval, the controller can drive the first motor 251 and the second motor 252 to work.

[0042] The present invention provides a method for cleaning dust from a mobile multimedia advertising machine, as follows:

[0043] 1. Control the first motor 251 and the second motor 252 to work, respectively drive the first lead screw 220 and the second lead screw to rotate and drive the first slider 231 and the second slider to move; the movement of the slider along the transverse square tube will cause the connecting rod 240 to move back and forth perpendicular to the first transverse square tube 211 / second transverse square tube 213;

[0044] 2. A rubber scraper 241 is fixed on one side of the connecting rod 240. The lower end of the rubber scraper 241 will contact the display surface of the advertising machine. When the connecting rod 240 moves, it will move the rubber scraper 241 with it. When the rubber scraper 241 slides along the direction of the connecting rod 240, it will shake off or scrape off the dust on the display screen.

[0045] It should be noted that rubber material has good flexibility and adaptability, and can make close contact with the display surface while avoiding damage to the display surface; under normal circumstances, the display screen of the advertising machine will be installed with a transparent protective shell, such as glass or transparent plastic shell.
