[0013] By adopting the above technical solution, when in use, ventilation and heating in the seat cushion body and the back cushion body can achieve ventilation and heating effects on the entire backrest and seat cushion, and the ventilation shell controls the airflow direction in the seat cushion body and the back cushion body.

[0014] As a further solution of the utility model: the side surface of the cushion body is connected to a power plug via a cable.

[0015] By adopting the above technical solution, the power plug is connected to the 12V power socket in the car, which facilitates power supply to the components in the ventilation shell.

[0016] As a further solution of the utility model: the ventilation shell includes a fan, the fan is installed in the ventilation shell, and a connecting pipe is connected to one side of the ventilation shell, a heating wire is installed on one side of the ventilation shell close to the connecting pipe, and the connecting pipe is connected to the air pipe.

[0017] By adopting the above technical solution, when in use, negative pressure is generated by the fan or air is blown toward the seat cushion body and the back cushion body, and the heating wire is activated during the blowing, thereby achieving ventilation and heating effects for the seat.

[0018] Compared with the prior art, the utility model has the following beneficial effects: the car seat cushion with heating and ventilation functions,

[0019] An air pipe, a support block and a vent are provided. The support block in the air permeable layer plays a supporting role to prevent the PU sponge layer above from being compressed and causing the vent holes on the air pipe to be blocked. The vent holes on the air pipe are opened laterally. This design can prevent the vent holes from being blocked and causing ventilation failure.

[0020] In addition, the car seat cushion with heating and ventilation functions is also provided with a ventilation shell. During ventilation, the heating wire is closed and the fan draws air outward so that the hot air between the human body and the seat cushion is discharged. During heating, the fan blows air toward the seat cushion and the heating wire heats the air to achieve a heating effect. BRIEF DESCRIPTION OF THE DRAWINGS
