[0026] In this embodiment, a humidity sensor 5 is disposed on the partition 18 , and the humidity sensor 5 is electrically connected to the control box 12 .

[0027] In this embodiment, the air induction mechanism includes an air induction groove 9 arranged in the display screen frame 1, and two air induction cavities 16 are arranged in the air induction box 10 through a partition 18.

The induced draft fan 17 introduces the air in the display screen frame 1 through the induced draft groove 9, and then discharges it into the exhaust main pipe 8 through the exhaust branch pipe 11, and then discharges it into the moisture absorption box 6 through the exhaust main pipe 8. The air in the display screen frame 1 is sucked in and dried by the induced draft mechanism, so as to realize air circulation and dehumidification.

[0029] Furthermore, the sound-absorbing cotton layer 15 can reduce the noise generated when the induced draft fan 17 is working, and the buffer layer 14 can reduce the vibration of the induced draft fan 17 during operation, thereby further reducing the noise.

[0031] Specifically, the air discharged into the desiccant box 6 through the exhaust main duct 8 first passes through the desiccant cotton 19 to absorb moisture, and then passes through the multi-layer desiccant box 21 to dry the humid air in the desiccant box. The dried air enters the display screen frame 1 again through the connecting pipe 23 to dehumidify the display screen frame 1.

[0032] In this embodiment, the display screen frame 1 is provided with ventilation holes 13, and a filter is provided in the ventilation holes 13.

In conjunction with the air induced mechanism and the moisture absorption box 6, air circulation and dehumidification are achieved to maintain the interior of the display screen frame 1 dry.

[0035] In the utility model, the noise generated by the induced draft fan during operation can be reduced by the sound-absorbing cotton layer 15 on the outer ring of the induced draft inner cavity 16, and the vibration of the induced draft fan 17 during operation can be reduced by the buffer layer 14, thereby further reducing the noise.

[0036] Under the premise that no conflict occurs, those skilled in the art may freely combine and superimpose the above-mentioned additional technical features.
