[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figures 1-2 An electronic whiteboard with a dustproof structure is shown, including an electronic whiteboard screen 1. A fixed box 2 is fixedly installed on the top of the electronic whiteboard screen 1. A movable box 3 is movably installed on the top of the fixed box 2. One end of the movable box 3 extends forward. The inner cavity of the movable box 3 is rotatably connected to a rotating shaft 4 through a bearing. The bottom of the rotating shaft 4 extends downward to the outside of the movable box 3 and is fixed with a cleaning brush 5 for cleaning dust from the surface of the electronic whiteboard screen 1. The outer side of the cleaning brush 5 is in contact with the surface of the electronic whiteboard screen 1. The inner cavity of the fixed box 2 is provided with a translation component 6 for moving the movable box 3 left and right so that the cleaning brush 5 can thoroughly clean the electronic whiteboard screen 1.

[0023] The movable box 3 is moved horizontally on top of the fixed box 2 by the translation component 6. Then, the movable box 3 moves the rotating shaft 4 and the cleaning brush 5 to clean the dust on the outside of the electronic whiteboard screen 1, preventing dust from adhering to the surface of the electronic whiteboard screen 1 and affecting its use. At the same time, the movable box 3 can be rotated to adjust its position and adjust the position of the cleaning brush 5 to prevent the cleaning brush 5 from affecting the use of the electronic whiteboard screen 1 from the front. Together with the traditional dust cover, it is convenient to perform dust prevention and cleaning treatment on the electronic whiteboard screen 1 at different usage periods.

[0024] The translation component 6 includes a drive motor 61 fixed to one side of the inner cavity of the fixed box 2. The output shaft of the drive motor 61 is fixed with a long screw 62. The end of the long screw 62 away from the drive motor 61 rotates to the other side of the inner cavity of the fixed box 2 via a bearing. A movable block 63 is movably arranged in the inner cavity of the fixed box 2. A screw sleeve 64 is embedded inside the movable block 63. The screw sleeve 64 is sleeved on the outside of the long screw 62 and threadedly connected to the long screw 62. The movable block 63 extends through to the outside of the fixed box 2 and is fixedly connected to the bottom of the movable box 3. The drive motor 61 provides driving force. By utilizing the cooperation between the long screw 62 and the screw sleeve 64, the movable block 63 moves in the inner cavity of the fixed box 2, which facilitates the translation of the movable box 3 and the cleaning brush 5.

[0025] The bottom of the electronic whiteboard screen 1 is equipped with a slide rail 16. The inner cavity of the slide rail 16 is provided with a cylindrical slider, and the slider extends through the bottom of the slide rail 16 and is fixed with a connecting plate 17. The bottom of the rotating shaft 4 is rotatably connected to the connecting plate 17 through a bearing. The cooperation between the slide rail 16 and the connecting plate 17 makes it easy to limit the rotation shaft 4 and prevent the rotating shaft 4 from shaking, which would prevent the cleaning brush 5 from adhering to the electronic whiteboard screen 1 and thus fail to achieve the purpose of cleaning and dust prevention.

[0026] The difference from Example 1 is that, as Figure 3 As shown:

[0027] The top of the fixed box 2 is provided with a through groove. The top of the movable block 63 is rotatably connected to the connecting shaft 7 through the bearing. The top of the connecting shaft 7 passes through the through groove and is fixed to the bottom of the movable box 3. With the cooperation of the connecting shaft 7, it is convenient to connect the movable block 63 and the movable box 3. At the same time, it can ensure that the movable box 3 can rotate on the top of the fixed box 2 to adjust the position between the cleaning brush 5 and the electronic whiteboard screen 1.

[0028] Based on Example 1 or Example 2, the scope can be expanded, such as... Figure 4 As shown:

[0029] A rotary motor 8 is fixed at the bottom of the inner cavity of the active box 3. A drive pulley 9 is fixed to the output shaft of the rotary motor 8. A driven pulley 10 is fixed to the surface of the rotary shaft 4. The drive pulley 9 and the driven pulley 10 are connected by a transmission belt. The rotary motor 8 drives the drive pulley 9 to rotate, and then the transmission belt drives the driven pulley 10 to rotate, so that the rotary shaft 4 rotates under the drive of the rotary motor 8, ensuring the rotation of the cleaning brush 5 and cleaning the dust on the outside of the electronic whiteboard screen 1.

[0030] Based on Example 2, the following additions are made: Figure 5 As shown:

[0031] The movable box 3 has through holes at both the top and bottom, and a movable rod 11 is movably installed in the inner cavity of the through holes. A limiting plate 12 located in the inner cavity of the movable box 3 is fixed to the outside of the movable rod 11. A support spring 13 is sleeved on the outside of the movable rod 11. The top of the support spring 13 is fixed to the top of the inner cavity of the movable box 3, and the bottom of the support spring 13 is fixed to the top of the limiting plate 12. A limiting groove 14 is opened at the top of the fixed box 2. The bottom of the movable rod 11 passes through the inner cavity of the limiting groove 14. Through the cooperation of the support spring 13 and the limiting plate 12, the movable rod 11 moves downward through the through hole and engages with the limiting groove 14, so that the movable box 3 and the fixed box 2 are limited to prevent the movable box 3 from rotating around the connecting shaft 7, which would cause pressure changes between the cleaning brush 5 and the electronic whiteboard screen 1. At the same time, when the movable box 3 moves to the end of the fixed box 2, the position of the cleaning brush 5 can be adjusted by rotating the movable box 3 to prevent the cleaning brush 5 from affecting the use of the electronic whiteboard screen 1.

[0032] The upper end of the movable rod 11 has a circular hole, and a pull ring 15 is movably installed in the inner cavity of the circular hole. The pull ring 15 facilitates the movement and stretching of the movable rod 11.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
