An assembly plate 4 is fixedly connected inside the soundproof air outlet box 3. Multiple silencers 5 are fixedly connected to the assembly plate 4. When the airflow generated by the air conditioner... When the sound is first introduced into the soundproof air outlet box 3, the silencer 5 absorbs and reflects some of the sound waves, significantly reducing the propagation of noise. Inside the soundproof air outlet box 3, a jet tube 6 is fixedly connected to one side of the silencer 5. The design of the jet tube 6 helps to optimize the airflow path. An adjustment component 9 is provided on one side of the soundproof air outlet box 3. Inside the soundproof air outlet box 3, a grille plate 8 is rotatably connected to the adjustment component 9. The grille plate 8 consists of multiple small holes or gaps, which are used to further disperse and slow down the airflow speed, reduce the direct friction between the airflow and the air outlet material, and thus further reduce noise.

[0024] refer to Figure 3 The jet tube 6 is fixedly connected to a streamlined air duct 7, which is composed of multiple baffles. By setting the streamlined air duct 7, which is composed of multiple baffles, the formation of vortices can be further reduced, thereby improving the air outlet efficiency.

[0025] refer to Figure 3 A flow divider 13 is provided between the assembly plate 4 and the jet tube 6, and one side of the silencer 5 extends into the interior of the flow divider 13; by providing the flow divider 13, it helps to disperse the airflow into multiple jet tubes 6.

[0026] refer to Figure 5The adjustment component 9 includes a motor 91, which is fixedly connected to the soundproof air outlet box 3. A transmission rod 95 is rotatably connected inside the soundproof air outlet box 3. The grille plate 8 is fixedly connected to the transmission rod 95. A first sprocket 92 is fixedly connected to the output end of the motor 91. The first sprocket 92 is driven by a chain 93 to a second sprocket 94.

[0028] Operating principle and advantages: First, the soundproof air outlet box 3 is securely installed on the mounting frame 2 of the air conditioner body 1 using the fixing component 10, ensuring that the soundproof air outlet box 3 can work normally and isolate noise. When the air conditioner starts running, the generated airflow first enters the soundproof air outlet box 3. At this time, multiple silencers 5 start working, absorbing and reflecting some of the sound waves, significantly reducing the propagation of noise. Subsequently, the airflow enters the distribution chamber 13 and is dispersed into multiple jet tubes 6. The streamlined air ducts 7 inside the jet tubes 6 further optimize the airflow path. To reduce the formation of eddies and improve air outlet efficiency, the airflow then enters the area of ​​the grille plate 8. The grille plate 8 consists of multiple small holes or gaps, which are used to further disperse and slow down the airflow speed, reduce the direct friction between the airflow and the air outlet material, and thus reduce noise. When it is necessary to remove and replace the soundproof air outlet box 3, rotate the torsion block 105 to drive the screw 104 to rotate, so that the slide plate 103 on the surface of the screw 104 moves. The slide plate 103 drives the plug block 102 to move. The plug block 102 leaves the plug slot 101, and the soundproof air outlet box 3 can be removed for maintenance.
