It is a display tool that displays certain electronic files on the screen through specific transmission equipment and then reflects them to the human eye. According to different materials, it can be divided into cathode ray tube displays, plasma displays, liquid crystal displays, etc., and most advertising screens use an LED liquid crystal display, an electronic display, which is packaged into a module by individual LED lamp beads, and then spliced ​​into a display screen of any size through multiple modules. It is used to display text, video and other information. It is mainly used in advertising, conferences, information release and other fields.

[0003] After checking the announcement number: CN 218191164 U, an advertising machine with a cleaning function is disclosed. This technology discloses "including a machine body, a display screen and an infrared sensor, one end of the machine body is provided with a cleaning component, the cleaning component includes a moving frame, one end of the moving frame is connected with a threaded rod, the threaded rod is rotatably connected with the machine body through a bearing, a motor is installed on the inner bottom wall of the machine body, the output end of the motor passes through the machine body and is connected to the threaded rod, the other end of the moving frame is connected with a limit rod, the limit rod is fixedly connected with the machine body, the end of the moving frame close to the machine body is connected with a mounting seat, and the interior of the mounting seat is provided with cleaning cotton.

[0004] With regard to the above-mentioned related technologies, the inventors believe that during the use of most advertising screens, a large amount of dust will accumulate on the outer surface of the screen, which greatly reduces the display effect, reduces the service life of the display screen, and affects the viewing experience, resulting in the need for manual cleaning or repair of the screen at regular intervals. The operation is rather troublesome and most of them require high-altitude operations, which are highly dangerous and increase the cleaning cost. In addition, due to the inconvenient location, the cleaning force is not strong and the efficiency is low. Utility Model Content
