The front row of blowing foot outlets 110 may be one, i.e., the main driver's seat and the auxiliary driver's seat share one blowing foot outlet. As shown in fig. 3, the front row of blowing foot outlets 110 may be two, namely a first sub-front row of blowing foot outlets 111 and a second sub-front row of blowing foot outlets 112. The first sub-front row foot-blowing outlet 111 is located near the position of the main driver's seat, and the second sub-front row foot-blowing outlet 112 is located near the position of the auxiliary driver's seat. For example, the first front sub-row blowing pin outlet 111 and the second front sub-row blowing pin outlet 112 are disposed opposite to each other, and the air outlet direction of the first front sub-row blowing pin outlet 111 is opposite to the air outlet direction of the second front sub-row blowing pin outlet 112. The air flow flowing out from the first sub-front row foothold outlet 111 flows in the direction of the main driver's seat, and the air flow flowing out from the second sub-front row foothold outlet 112 flows in the direction of the auxiliary driver's seat. Of course, the number of the front row footer outlets 110 may be more than three, and the present application is not limited thereto.

The rear row of blowing foot outlets 120 may be one, i.e., the rear left seat and the rear right seat share one blowing foot outlet. The number of the rear row of blowing pin outlets 120 may be two, namely a first sub-rear row of blowing pin outlets 121 and a second sub-rear row of blowing pin outlets 122. The first sub-rear-row footbath outlet 121 corresponds to the position of the rear left seat, and the second sub-rear-row footbath outlet 122 corresponds to the position of the rear right seat.
