The driving ends are respectively fixedly provided with fans 19 and 20, the inner side walls of the support plate 23 are fixedly connected with baffles 11 and 212, baffles 11 and 212 correspond to fans 19 and 210 respectively, a ventilation pipe 13 is fixedly connected between the outer wall of the motor 17 and the baffle 11, a ventilation pipe 214 is fixedly connected between the outer wall of the motor 28 and the baffle 212, both ventilation pipes 13 and 214 are elastic and therefore have high bending ability, and fans 19 and 210 are respectively located in the ends of ventilation pipes 13 and 214.

[0021] The outer walls of ventilation duct 13 and ventilation duct 2 14 are both provided with air outlet slots, which are parallel to the axes of ventilation duct 13 and ventilation duct 2 14. The air outlet slots of ventilation duct 13 and ventilation duct 2 14 are both inclined upward to form an angle with the back of the curved screen 1. The outer walls of ventilation duct 13 and ventilation duct 2 14 are both fixedly provided with multiple positioning plates 5 17, and the inner wall of support plate 2 3 is fixedly connected with positioning plate 3 15 and positioning plate 4 16. Positioning holes are provided on positioning plate 1 5, positioning plate 2 6, positioning plate 3 15, positioning plate 4 16 and positioning plate 5 17, and positioning holes can be used to fix positioning plate 1 5, positioning plate 2 6, positioning plate 3 15, positioning plate 4 16 and positioning plate 5 17 to a supporting structure such as a wall with bolts, so that ventilation duct 13 and ventilation duct 2 14 are parallel to the curved screen 1.

[0022] The positioning plate 1 5 is located in the middle section of the supporting plate 1 2 , and the positioning plate 2 6 is located at the lower end of the supporting plate 1 2 , so that the ventilation pipe 1 13 and the ventilation pipe 2 14 are respectively located in the middle and lower parts of the curved screen 1 , and there is a spacing between the ventilation pipe 1 13 , the ventilation pipe 2 14 and the curved screen 1 to facilitate the air to be blown out from the air outlet slot to the curved screen 1 .
