A display device is a device used to display the results of information technology. However, the surface of existing display devices will be contaminated with a certain amount of dust after a long period of display. When cleaning the dust, it is manually wiped with a rag. The overall operation process is too cumbersome, which affects the efficiency of cleaning.

[0003] After searching, China disclosed an information technology display device with patent publication number CN219933434U on October 31, 2023, which is roughly described as including a base, a support column fixedly connected to the top of the base, a horizontal cover fixedly connected to the top of the support column, and display screens fixedly connected to both sides of the support column, and a transmission box is fixedly connected to both sides of the bottom of the horizontal cover, and a motor is fixedly connected to the inner side of the back of the inner cavity of the transmission box, and a bevel gear 1 is fixedly connected to the output end of the motor, and a screw is laterally connected to the interior of the transmission box through a bearing, and a bevel gear 2 is sleeved on the inner side of the screw surface, and the back of the bevel gear 2 is meshed with the bevel gear 1, and a screw block is threadedly connected to the right side of the screw surface and on the left side of the bevel gear 2.

[0004] Although the above-mentioned prior art solution avoids the traditional manual wiping and cleaning with a rag, thereby improving the cleaning efficiency, the cleaning plate of the device is not easy to disassemble and will become dirty after long-term use. Therefore, it is not easy to clean and replace, which affects the cleaning effect. Utility Model Content
