The guide plate assembly 3 is disposed inside the air duct assembly and is used to guide the airflow in layers. The fan module 4 is installed at one end of the air duct assembly and is used to introduce external air into the air duct assembly and push the airflow along a preset path. The fixing bracket 5 is used to fix the air duct assembly inside the seat body 1.

[0024] Example 2:

[0025] like Figures 1 to 3 As shown, this utility model provides a ventilation and airflow guiding device for a car seat, including a seat body 1, an air duct assembly, a guide plate assembly 3, a fan module 4, and a fixing bracket 5. The air duct assembly is embedded inside the seat body 1 and is used to guide the flow path of airflow within the seat body 1. The guide plate assembly 3 is disposed inside the air duct assembly and is used to guide the airflow in layers. The fan module 4 is installed at one end of the air duct assembly and is used to introduce external air into the air duct assembly and push the airflow along a preset path. The fixing bracket 5 is used to fix the air duct assembly inside the seat body 1.

[0026] By integrating the air duct assembly, air guide plate group 3, fan module 4 and fixing bracket 5 inside the seat body 1, a complete ventilation system is formed, ensuring that the components work together and improving overall performance.

[0027] The air duct assembly guides the airflow path within the seat body 1, the air guide plate group 3 guides the airflow in layers, and the fan module 4 pushes the airflow along a preset path to ensure efficient and uniform ventilation.

[0028] The fixed bracket 5 securely fixes the air duct assembly inside the seat body 1, ensuring the stable operation of the ventilation system and preventing airflow interruption or increased noise due to vibration.
