The air outlet 5 is provided with several air guide plates 6 distributed in a vortex shape, and an airflow channel 7 is formed between two adjacent air guide plates 6. The working principle of the air purification device is as follows: When the air purification device is installed in the plant planting environment, the fan 3 is working. Outside air enters the purification body 1 through the air inlet 4, and then passes through the filter module 2. The filter module 2 adsorbs harmful gases, odors, and impurities in the air, thus purifying the air. After being filtered by the filter module 2, the air enters the fan 3 and is then discharged back into the planting environment through the air outlet 5, realizing air circulation and purification.

[0031] The air guide plate 6 has a gradient, curved shape and is streamlined. A central airflow channel 8 is formed between the various air guide plates 6, and an angle is formed between the air guide plate 6 and the central airflow channel 8. The air guide plate 6 at a specific angle ensures stable transmission of wind speed and avoids uneven airflow. The multi-segment air guide plate 6 design allows the angle of each segment to be adjusted according to wind speed and air volume requirements, thereby improving airflow distribution and making the air diffuse evenly in the space without generating local wind pressure differences. The above design makes the air guide cover 9 a very safe protective cover, which can prevent foreign objects, small animals, fingers, etc. from accidentally entering.
