The seat is mainly composed of a seat cushion, a backrest and a headrest, providing a good riding experience for the driver and passengers. When the driver and passengers sit on the seat cushion for a long time, the driver and passengers are in contact with the seat for a long time, which can easily make their buttocks sweat, reducing the riding experience of the driver and passengers. Therefore, car seats in the prior art are generally equipped with seat heating and ventilation functions to allow passengers to have a better ride.

[0003] The ventilated seats in the prior art usually refer to seats with ventilation fans installed at the bottom of the seat cushions, so that the ventilation fans introduce the airflow in the cab into the seat cushions, and then discharge the airflow through the seat cushions, so that the seat cushions have ventilation functions. However, the ventilated seats in the prior art usually also heat the airflow during use, so that the seat cushions have a heating function while satisfying the ventilation function, thereby improving the driving experience of the driver and passengers in cold weather. However, in the process of heating the airflow, the airflow is usually heated during the process of the airflow flowing in the seat cushion and the process of the electric heating wire contacting the airflow. However, due to the large changes in ambient temperature, the environment in the vehicle cab changes greatly even within one day, so the air volume and temperature of the seat ventilation and heat dissipation are inconsistent in different time periods.

[0026] An airflow heating mechanism is arranged in the middle of the mounting frame 4, and the airflow distribution mechanism is connected with the airflow heating mechanism. The airflow heating mechanism comprises a mounting cylinder 24 and an electric heat resistance wire 25. The mounting cylinder 24 is connected with the slope exhaust groove 8.

After the airflow enters the mounting cylinder 24 through the slope exhaust groove 8, the airflow contacts the electric heat resistance wire 25, so that the airflow temperature is increased. When the heated airflow is discharged, the ventilation and heating function of the seat cushion 1 is realized. The area control component includes a flip plate 26, a through hole 28 and a driving electric cylinder 29.

The exhaust cylinder 18 and the exhaust pipe 36 are connected by an air pipe 38. After the airflow is heated, the airflow in the installation cylinder 24 is transported to the ventilation cylinder 32 through the transport pipe 33, and then the airflow passes through the ventilation cylinder 32 and enters the exhaust pipe 36. After being discharged through the air outlet holes 37 and passing through the air outlet groove 35, the heated airflow enters the seat cushion 1, completing the ventilation and heating of the seat cushion 1. The ventilation cylinder 32 keeps the corresponding area of ​​the seat cushion 1 heated, thereby achieving the heating operation of the seat cushion 1. When there is no need to heat the airflow and the airflow is discharged directly, the airflow is directly transported from the discharge cylinder 18 through the air pipe 38 to the exhaust pipe 36, so that the normal temperature airflow is directly discharged through the exhaust pipe 36 to realize the ventilation operation of the seat cushion 1. Under the action of the stop valve, the airflow is prevented from entering the ventilation cylinder 32.

When the closing plate 13 is flipped downward and the elastic closing layer 15 is extended downward, the sloped exhaust groove 8 and the mounting cylinder 24 are temporarily kept closed. At this time, the bottom of the closing cylinder 16 is moved out of the exhaust port 17. After the airflow enters the sloped exhaust groove 8, the airflow is discharged into the upper area of ​​the closing plate 13 through multiple exhaust ports 17. The airflow enters between the closing cylinder 16 and the discharge cylinder 18 through the air inlet opened on the closing cylinder 16, and the airflow is directly transported from the discharge cylinder 18 to the exhaust pipe 36 through the air pipe 38, so that the normal temperature airflow is directly discharged through the exhaust pipe 36, thereby realizing the ventilation operation of the seat cushion 1.
