[0002] As is known, advertising light boxes use blister, acrylic, spray-painted cloth and other materials as base materials, and adopt box-type hollow structure advertising carriers, which are mainly suitable for indoor and outdoor advertising.

[0003] For example, the authorization announcement number is CN108376524B, and the authorization announcement date is May 12, 2020. The title is "A Self-Cleaning Insect Repellent Advertising Light Box." Its basic scheme is as follows: a water tank is opened on the top of the light box shell, and a limit hole is set at the bottom of the water tank. A compression spring and a piston are arranged at the bottom of the limit hole from top to bottom. A water outlet is opened on the rear wall of the shell and connected to the lower part of the limit hole. The thickness of the piston is less than the distance between the highest point of the water outlet and the lowest point of the water tank. The water outlet is connected to the top of a pleated airbag hung on the rear wall of the shell. A slide groove is set on both sides of the airbag, and a conversion rod set at the bottom of the airbag extends into the slide groove...

[0004] Another example is the authorization announcement number CN107424529A, the authorization announcement date is 2017.12.01, and the name is an automatic cleaning advertising light box, which includes an advertising box body. The advertising box body is provided with a self-cleaning device that can clean the outer surface of the advertising box body.
