Description

Technical Field

[0001] The utility model relates to the technical field of advertising machines, in particular to a heat dissipation and dust removal device for outdoor advertising machines. Background Art

[0002] Advertising machines are a new generation of intelligent devices. They form a complete advertising broadcast control system through terminal software control, network information transmission and multimedia terminal display, and use multimedia materials such as pictures, text, video, small plug-ins (weather, exchange rate, etc.) for advertising. Outdoor advertising machines are exposed to high temperature for a long time in the hot summer, and the internal heat dissipation effect is not good. At the same time, external dust will adhere to the outer surface of the display during use, thus affecting the clarity of the display. At present, the cleaning effect of the display is not good.
