A plurality of connecting blocks 2 are installed on the outer wall of the air outlet frame 1. A plurality of air outlets 4 are provided on the air outlet frame 1. A plurality of diffuser vanes 5 are rotatably installed on the side wall of the air outlet 4;

[0026] A regulating plate 7 slides out through the upper side of the middle part of the diffuser vane 5. A moving block 8 is rotatably installed at the top of the regulating plate 7. A threaded hole 9 is provided on the moving block 8. A threaded shaft 12 is installed through the inner sides of a plurality of the threaded holes 9 on the same straight line in a threaded fit. A motor 13 connected to the end of one of the threaded shafts 12 is installed on the inner wall of the air outlet frame 1. Conical gears 14 engaged with each other are installed in the middle of the two threaded shafts 12. The thread directions of the threaded shafts 12 on both sides of the conical gear 14 are opposite.

[0027] With the above structure, the air outlet frame 1 can be installed on the ceiling frame by bolts passing through a plurality of connecting blocks 2. The air blown out by the central air conditioner enters the inside of the air outlet frame 1 and is discharged through a plurality of air outlets 4 on the air outlet frame 1. The air outlet direction is adjusted by the rotation of a plurality of diffuser vanes 5;

[0028] By driving one of the threaded shafts 12 to rotate by the motor 13, the two threaded shafts 12 rotate simultaneously through the conical gears 14 engaged with each other in the middle of the two threaded shafts 12. The moving block 8 moves horizontally through the cooperation of the threaded shaft 12 and the threaded hole 9. The moving blocks 8 on both sides of the conical gear 14 move closer to or away from each other at the same time. The top of the regulating plate 7 is driven by the moving block 8 to move horizontally. The regulating plate 7 expands and contracts in the diffuser vane 5, driving the diffuser vane 5 to rotate, realizing the adjustment of the air outlet direction. The specific structure is as follows:

[0029] Combined with the attached Figure 1 and the attached Figure 3 As shown in the figure, the heights of a plurality of the threaded holes 9 on the same straight line are the same, and the heights of the two threaded shafts 12 are different;

[0030] A protective cylinder 10 is installed at the center of the upper side of the bottom of the air outlet frame 1. The two conical gears 14 are located inside the protective cylinder 10. The protective cylinder 10 is provided with through holes 11 for the threaded shafts 12 to pass through.

[0031] With the above structure, the two threaded shafts 12 intersect, enabling the conical gears 14 on the threaded shafts 12 to be engaged with each other, and enabling the two threaded shafts 12 to rotate simultaneously;

[0032] The two conical gears 14 are protected by the protective cylinder 10, preventing the fingers of maintenance personnel from being squeezed between the two conical gears 14 during maintenance. The conical gear 14 is sleeved on the outer side of the threaded shaft 12 and is fixedly connected to the threaded shaft 12 by bolts. The threaded shaft 12 rotates inside the through hole 11.

[0033] Combined with the attachedFigure 2 As shown, connecting shafts 6 are respectively installed on the opposite side walls of the diffuser 5. The axes of the two groups of connecting shafts 6 are on the same straight line and the other ends are rotatably connected to the air outlet frame 1.

[0034] With the above structure, when the diffuser 5 rotates, the connecting shaft 6 rotates and is connected in the side wall of the air outlet frame 1.

[0035] Embodiment 2

[0036] On the basis of Embodiment 1, please refer to the appendix Figure 1 , an infrared receiver 15 connected to the motor 13 is installed on the inner wall of the air outlet frame 1;

[0037] A dust-proof strip 3 is installed between the outer walls on the four sides of the air outlet frame 1.

[0038] With the above structure of Embodiment 2, it is convenient to control the start-stop and steering of the motor 13 through the remote control by the infrared receiver 15. The gap between the air outlet frame 1 and the ceiling is closed by the dust-proof strip 3, playing the role of dust-proof and aesthetic.
