[0023] In this solution, the silent fan 12 in the fixed frame 2 is started, and the through slot 10 provided on the fixed frame 2 is connected with the wind slot 11. The silent fan 12 sucks in the outside air and blows it out through the wind slot 11. When the air passes through the inside of the fixed frame 2, it will take away some of the heat emitted from the rear end of the TFT screen body 1, thereby improving the heat dissipation capacity of the TFT screen body 1. At the same time, the air blown out through the wind slot 11 will blow off the dust on the surface of the TFT screen body 1, thereby avoiding the wear of the surface of the TFT screen body 1 caused by cleaning with paper towels and rags. The tilted setting The auxiliary block 13 not only prevents the fallen dust from accumulating at the lower end of the TFT screen body 1, but also prevents water droplets from entering the interior of the TFT screen body 1 along the pores when the surface of the TFT screen body 1 meets water, thereby causing damage to the TFT screen body 1. The push block 20 is pulled, and the push block 20 rotates and slides in the empty groove 19, thereby driving the rotation of the baffle 18. Through the rotation of the baffle 18, the wind direction blown out of the wind slot 11 can be adjusted. At the same time, when the cleaning component is not in use, the wind slot 11 can be blocked by the baffle 18 to prevent dust from entering the fixed frame 2.

[0025] Specifically, when the height of the TFT screen body 1 needs to be adjusted, the knob 9 is turned to drive the limit block 8 to slide in the slide groove 7, thereby releasing the limit on the fixed column 4, and then the fixed column 4 is slid up in the sleeve 5. After the fixed column 4 slides up to the specified height, the knob 9 is tightened to drive the limit block 8 to lock the fixed column 4, thereby facilitating the adjustment of the height of the TFT screen body 1 and improving the comfort when using the TFT screen body 1.

[0026] Reference Figure 4 and Figure 6 In a preferred embodiment, the dustproof component includes a dustproof frame 14 slidably connected to the lower end of the fixed frame 2, a first filter 15 is arranged at the lower end of the dustproof frame 14, a second filter 16 is arranged at the upper end of the dustproof frame 14, and filter cotton 17 is filled between the first filter 15 and the second filter 16 inside the dustproof frame 14, a card slot 21 is opened on the left and right sides of the lower end of the fixed frame 2, a flexible card 22 is fixedly installed at the lower end of the dustproof frame 14, and a card block 23 is fixedly installed on the upper end of the flexible card 22 near the central axis.

[0027] Specifically, when the cleaning component is in use, the outside cold air will be sucked into the fixed frame 2, and the cold air will first pass through the dustproof frame 14. The first filter 15, the second filter 16 and the filter cotton 17 inside will cooperate to block impurities in the cold air and prevent the cold air from containing dust and affecting the cleaning work. When the first filter 15, the second filter 16 and the filter cotton 17 need to be replaced, the flexible card 22 is pushed to both sides to disengage the card block 23 from the card slot 21, and the dustproof frame 14 is pulled out of the fixed frame 2, and then the internal components are replaced, which is convenient for replacing the first filter 15, the second filter 16 and the filter cotton 17.

[0028] Working principle: When in use, start the silent fan 12 in the fixed frame 2, the through slot 10 opened on the fixed frame 2 is connected with the wind slot 11, the silent fan 12 sucks in the outside air, and then blows it out through the wind slot 11. When the air passes through the inside of the fixed frame 2, it will take away some of the heat emitted from the rear end of the TFT screen body 1, thereby improving the heat dissipation capacity of the TFT screen body 1. At the same time, the air blown out through the wind slot 11 will blow off the dust on the surface of the TFT screen body 1, thereby avoiding the wear on the surface of the TFT screen body 1 caused by cleaning with paper towels and rags. The inclined auxiliary block 13 not only prevents the fallen dust from accumulating at the lower end of the TFT screen body 1, but also prevents water droplets from entering the interior of the TFT screen body 1 along the pores when the surface of the TFT screen body 1 encounters water, thereby causing damage to the TFT screen body 1. The push block 20 is pulled, and the push block 20 rotates and slides in the empty groove 19, thereby driving the rotation of the baffle 18. Through the rotation of the baffle 18, the wind direction blown out of the wind slot 11 can be adjusted. At the same time, when the cleaning component is not in use, the wind slot 11 can be blocked by the baffle 18 to prevent dust from entering.
