The top of the screw rod 9 is movably connected with the bottom of the vertical plate 8 through a bearing. A transmission plate 10 is threadedly connected to the surface of the screw rod 9. The left side of the transmission plate 10 penetrates through the return groove 4 and is fixedly connected to the surface of the diversion plate 3. A transmission motor 11 for driving the screw rod 9 to rotate is fixedly connected to the top of the vertical plate 8.

[0031] As a technical optimization scheme of the present utility model, by setting the vertical plate 8, the screw rod 9 and the transmission plate 10, the diversion plate 3 can be automatically pushed to move, which can improve the adjustment efficiency of the diversion plate 3.

[0032] Reference Figure 2 , the bottom of the inner wall of the connection frame 6 is fixedly connected with guide rods 12 located on both sides of the screw rod 9. The top of the guide rods 12 penetrates through the transmission plate 10 and is fixedly connected to the bottom of the vertical plate 8. The guide rods 12 are slidably connected with the transmission plate 10.

[0033] As a technical optimization scheme of the present utility model, by setting the guide rods 12, the transmission plate 10 can be limited, avoiding the phenomenon that the transmission plate 10 tilts during the movement.

[0034] Reference Figure 3 , through holes 13 are formed on the surfaces of both the transmission plate 10 and the vertical plate 8. A reinforcing rib 14 located inside the through hole 13 is fixedly connected to the inside of the transmission plate 10.

[0036] Reference Figure 2 , a limiting frame 15 is fixedly connected to the left side of the diversion plate 3. The limiting frame 15 is located on the top of the return groove 4.

[0037] As a technical optimization scheme of the present utility model, by setting the limiting frame 15, the air flow can be limited, avoiding the phenomenon that the air flow flows upward along the diversion plate 3 and moves excessively.

[0040] Working principle and usage process of the present utility model: During use, the arc surface at the bottom of the flow guide plate 3 is used to guide the airflow, enabling the airflow to enter the interior of the wall panel 1 through the limiting of the limiting frame 15 and utilize the return flow groove 4 and the opening 5 for circulation. When it is necessary to adjust the height of the return flow groove 4, the driving motor 11 is turned on. The driving motor 11 drives the screw rod 9 to rotate. The screw rod 9 uses the thread to push the driving plate 10 to move vertically. During the movement of the driving plate 10, the flow guide plate 3 is driven to displace synchronously. During the movement of the flow guide plate 3, the contact area with the ground increases and it is squeezed by the ground, causing its bottom to bend. While the flow guide plate 3 changes the bending angle of its bottom, the height of the return flow groove 4 on its surface also changes, thereby achieving the effect of flexibly adjusting the return flow height.

[0041] In summary: For this wall panel air return structure, the arc surface at the bottom of the flow guide plate 3 is used to guide the airflow, enabling the airflow to enter the interior of the wall panel 1 through the limiting of the limiting frame 15 and utilize the return flow groove 4 and the opening 5 for circulation. When the flow guide plate 3 moves vertically, during the movement of the flow guide plate 3, the contact area with the ground increases and it is squeezed by the ground, causing its bottom to bend. While the flow guide plate 3 changes the bending angle of its bottom, the height of the return flow groove 4 on its surface also changes, thereby achieving the effect of flexibly adjusting the return flow height.
