[0026] The swinging device 5 further comprises a clamping plate 53, an arc-shaped slot 54, a magnet 552 and a magnet 553. The clamping plate 53 is rotationally connected to the inner wall of the heat-conducting plate 51. The arc-shaped slot 54 is formed in the side of the fan group 52 away from the heat-conducting plate 51. The magnet 552 is fixedly connected to the inner wall of the air inlet frame 55. The magnet 553 is fixedly connected to the inner wall of the heat-conducting plate 51, and the magnet 553 is magnetically attracted to the magnet 552. The fan group 52 blows the heat absorbed by the heat-conducting plate 51 to the upper side and out of the display, which can further improve the heat dissipation effect of the display. The side of the clamping plate 53 away from the heat-conducting plate 51 is in contact with the inner wall of the arc-shaped slot 54. The front part of the air inlet frame 55 is in contact with the rear part of the heat-conducting plate 51. The surface of the bottom part of the push rod 551 is in contact with the surface of the moving plate 16. The swinging of the fan group 52 can increase the air inlet area of the box body 1, ensure that the dust is evenly distributed on the bottom part of the filter plate 13, and facilitate vibration and falling, preventing excessive dust accumulation in the middle part of the filter plate 13.

[0027] The working principle is that the mounting plate 3 is fixed on the wall surface by screws, and then the fixed block 8 is placed in the sliding groove 7 on the top of the mounting plate 3. At this time, the support plate 9 on the box body 1 is supported on the fixed plate 4 by the roller 10. At this time, the display can be moved left and right to adjust the position, which is convenient to use. At this time, the box body 1 moves to drive the fixed block 8 to move in the sliding groove 7, and the support plate 9 drives the roller 10 to roll on the fixed plate 4 and supports the box body 1 and the display screen 2. This connection method is convenient for removing the display for maintenance. At the same time, the fan 12 draws the external air at the bottom of the box body 1 into the box body 1 and cools and dissipates heat for the display, but dust also accumulates on the filter plate 13 at the air inlet. At this time, the motor 14 is intermittently started to drive the reciprocating screw 15 to rotate. The reciprocating screw 15 drives the moving plate 16 to move through the cross-type spiral groove and the clamping block in the moving plate 16. The moving plate 16 drives the pulley 17 to move on the filter plate 13, and the pulley 17 itself rotates to drive the cam 18 to rotate. The cam 18 drives the rotating rod 19 to rotate. The rotating rod 19 is reset by the torsional spring after the cam 18 continues to rotate and hits the filter plate 13. At this time, the vibration of the filter plate 13 promotes the dust accumulated at the bottom to fall, preventing dust accumulation and blocking the ventilation effect during heat dissipation.

[0028] The backlight source generates heat when the display is in use, at this time, the heat is conducted into the heat conduction plate 51, and the heat absorbed by the heat conduction plate 51 is blown to the upper side of the display and blown out of the display under the action of the fan group 52, so that the heat dissipation effect of the display can be further improved. When the moving plate 16 moves to push the push rod 551, the push rod 551 drives the fan group 52 to rotate on the heat conduction plate 51 through the air inlet frame 55, and the magnet two 553 in the air inlet frame 55 moves together to make the magnet two 553 on one side contact the magnet one 552 on the other side of the heat conduction plate 51 and attract each other. The arc-shaped groove 54 on the fan group 52 moves together, and the clamping plate 53 is displaced in the arc-shaped groove 54, so that the clamping plate 53 can fix the fan group 52 on the heat conduction plate 51 without affecting the rotation of the fan group 52. The swing of the fan group 52 can increase the air inlet area of the box body 1, ensure that the dust is relatively uniformly distributed on the bottom of the filter plate 13, facilitate vibration and falling, and prevent the dust from being accumulated too much in the middle of the filter plate 13 and being difficult to vibrate and fall.

The filter box 61 is installed at the bottom of the box body 1, the sliding plate 62 is slidingly connected to the inner wall of the filter box 61, and the mounting block 63 is fixedly connected to the bottom of the sliding plate 62. The transmission roller 64 is rotatably connected to the surface of the mounting block 63, the brush roller 65 is fixedly connected to the axis of the transmission roller 64, the transmission plate 653 is fixedly connected to the bottom of the sliding plate 62, and the scraping rod 654 is fixedly connected to the top and bottom of the transmission plate 653. The brush roller 65 will turn over the desiccant in the filter box 61 while the sliding plate 62 moves, thereby increasing the contact area of the desiccant with air and improving the drying effect and efficiency. The surface of the transmission roller 64 is in contact with the inner wall of the filter box 61, the surface of the transmission shaft 652 is rotatably connected to the inner wall of the box body 1, the front part of the telescopic rod 651 is in contact with the rear part of the box body 1, and the inner wall of the end of the telescopic rod 651 away from the transmission shaft 652 is rotatably connected to the rear part of the sliding plate 62 through a connecting rod, so as to ensure repeated absorption of moisture in the air, prevent humid air from contacting dust, and further cause the dust to be more firmly adhered to the filter box 61.

[0030] The working principle is that the air entering the box body 1 first enters the filter box 61, and the desiccant in the filter box 61 absorbs the moisture in the air, preventing the display from being affected by the service life in some humid environments, and the fan group 52 swings to drive the telescopic rod 651 to swing, the telescopic rod 651 drives the sliding plate 62 to reciprocate in the filter box 61 through the connecting rod, the sliding plate 62 drives the mounting block 63 to move, the mounting block 63 drives the transmission roller 64 to move in the filter box 61 and realize the rotation of the transmission roller 64, the transmission roller 64 drives the brush roller 65 to rotate, the brush roller 65 will move the desiccant in the filter box 61 at the same time as the sliding plate 62 moves, improve the contact area of the desiccant and the air and improve the drying effect and efficiency, and the sliding plate 62 moves to drive the transmission plate 653 to move, the transmission plate 653 drives the scraping rod 654 to move, the scraping rod 654 further stirs the desiccant, so that the repeated absorption of moisture in the air can be ensured, the humid air is prevented from contacting the dust, and the dust is more firmly adhered to the filter box 61.
