The diameter of the display screen body 1, the diameter of the bottom plate 5 and the diameter of the fixed plate 2 are all the same.

[0035] Specifically, the cleaning component 6 includes a cavity 601 opened inside the top plate 3 and a counterweight ring 608 arranged at the bottom of the top plate 3. A motor 602 is installed at the middle position inside the cavity 601, and the output end of the motor 602 is connected to a driving gear 603. Two wire wheels 605 are fixed inside the cavity 601. Two winding shafts 607 are provided at the lower part of the cavity 601 through bearings, and a driven gear 604 is installed at the top of the winding shaft 607. The driving gear 603 is meshed with the driven gear 604, and the winding shaft 607 is rotatably connected to the top plate 3. When the driving gear 603 rotates, it will drive the driven gear 604 to rotate, and the driven gear 604 will drive the winding shaft 607 to rotate. After the winding shaft 607 rotates, it will reel in or release the pull rope 606.

[0036] See also Figure 2-Figure 5, a pull rope 606 is wound around the outer wall of the winding shaft 607, one end of the pull rope 606 passes through the wire wheel 605 and is connected to the top of the counterweight ring 608, the inner wall of the cleaning brush ring 609 is in contact with the outer wall of the fixed plate 2, and when the winding shaft 607 rotates, it will loosen the pull rope 606. After the pull rope 606 is loosened, the counterweight ring 608 will move downward due to its own gravity, thereby driving the cleaning brush ring 609 to move downward, and the inner wall of the counterweight ring 608 is provided with a connecting ring 610, and the inner wall of the connecting ring 610 is installed with a cleaning brush ring 609, the cleaning brush ring 609 is detachably connected to the counterweight ring 608 through the connecting ring 610, when the counterweight ring 608 moves downward, it will drive the connecting ring 610 to move downward, and the connecting ring 610 drives the cleaning brush ring 609 to move downward, and the cleaning brush ring 609 can clean the dust or impurities attached to the outer wall of the display screen body 1, and a disassembly component 7 is provided inside the counterweight ring 608.

[0037] Embodiment 2:

[0038] On the basis of the above-mentioned embodiment 1, when the cleaning brush ring 609 has been cleaning for a long time, more dust or impurities will be attached to its cleaning surface. In order to prevent affecting the subsequent cleaning effect of the cleaning brush ring 609 on the display screen main body 1, the cleaning brush ring 609 needs to be removed so as to be replaced with a new cleaning brush ring 609, so as to facilitate the subsequent cleaning of the display screen main body 1. The cleaning brush ring 609 can be disassembled and replaced through the following structure.

[0039] See also Figure 2 and Figure 5 The disassembly component 7 includes a movable cavity 701 opened inside the counterweight ring 608, slots 708 opened on both sides of the connecting ring 610, and a threaded shaft 703 threadedly connected to the bottom of the counterweight ring 608. When the position of the top block 702 needs to be adjusted, the user can turn the knob, and the knob drives the threaded shaft 703 to rotate, and the threaded shaft 703 drives the top block 702 to move. A knob 705 is installed at the bottom end of the threaded shaft 703, and a limit rod 704 that penetrates to the outside of the counterweight ring 608 is connected to one side of the bottom of the top block 702.

[0040] Specifically, the top end of the threaded shaft 703 is connected to the top block 702 through a bearing. When the cleaning brush ring 609 needs to be removed, the top block 702 moves downward and no longer pushes the movable block 706 to move. The movable block 706 is reset and moves and drives the clamping block 707 to move. The clamping block 707 is adapted to the clamping slot 708. When the clamping block 707 is inserted into the inside of the clamping slot 708, the connecting ring 610 can be limited. The top block 702 contacts the movable block 706. The movable block 706 is slidably connected to the slide slot 709 through the slider 710. When the top block 702 moves upward, it will push the movable block 706 to move. The movement of the movable block 706 will drive the slider 710 to slide inside the slide slot 709, thereby improving the stability of the movable block 706 when moving. The movable block 706 is arranged inside the movable cavity 701, and a clamping block 707 extending to the inside of the clamping slot 708 is installed on one side of the movable block 706.

[0041] Embodiment three:

[0042] On the basis of the above-mentioned second embodiment, since the movement of the movable block 706 will drive the clamping block 707 to move, the stability of the movable block 706 during movement is poor. In order to ensure that the movable block 706 moves left and right, the following structure is set to enable the movable block 706 to move stably.

[0043] See also Figure 5 A slide groove 709 is provided at the top of the movable cavity 701, and a return spring 711 is fixed to one side of the inner side of the slide groove 709, one end of the return spring 711 is connected to a slider 710, and the bottom of the slider 710 is connected to the top of the movable block 706. When the movable block 706 moves to drive the slider 710 to slide inside the slide groove 709, the movable block 706 will stretch the return spring 711 so as to subsequently drive the movable block 706 to reset and move, and the setting of the slider 710 can ensure that the movable block 706 can move stably.

[0044] The implementation principle of this embodiment is as follows: first, the heat dissipation holes 4 can play a role in heat dissipation. When it is necessary to clean the dust or impurities attached to the outer wall of the display screen body 1, the user can start the motor 602. The motor 602 can drive the driving gear 603 to rotate, and then drive the driven gear 604 to rotate, and then drive the winding shaft 607 to rotate. After the winding shaft 607 rotates, the pull rope 606 will be loosened. At this time, the counterweight ring 608 will move downward due to its own gravity. When the counterweight ring 608 moves downward, it will drive the connecting ring 610 to move downward. The connecting ring 610 will drive the cleaning brush ring 609 to move downward. The cleaning brush ring 609 can clean the dust or impurities attached to the outer wall of the display screen body 1.

[0045] When the cleaning brush ring 609 needs to be disassembled for replacement, the user can rotate the threaded shaft 703 so that the threaded shaft 703 drives the top block 702 to move downward. When the top block 702 moves downward, it no longer pushes the movable block 706. At this time, the return spring 711 contracts and drives the slider 710 to return and move, and then drives the movable block 706 to return and move. The movable block 706 drives the clamping block 707 to move, so that the clamping block 707 moves out of the clamping slot 708 and no longer limits the connecting ring 610. At this time, the user can remove the connecting ring 610 and the cleaning brush ring 609 to replace the cleaning brush ring 609.
