[0068] By using the above scheme, only the air inlet channel 23 needs to be connected with the air conditioning system, so that the first air duct 11 and the second air duct 21 are both connected with the air conditioning system, which is simple and convenient, and makes the structure of the ventilation device more compact.

[0069] Please refer to Figures 8 to 10 , Figure 8 is Figure 7 A partial enlarged view at C in FIG. Figure 9 is Figure 7 A schematic view of moving the moving member 31 of the ventilation device shown to the first position, Figure 10 is Figure 7 A schematic view of moving the moving member 31 of the ventilation device shown to the second position.

[0071] By using the above scheme, the power member 32 can be used to drive the moving member 31 to move to the first position, so that the moving member 31 shields the second communication port 25, at this time, the air inlet channel 23 is only communicated with the first air duct 11 through the connecting air duct 27 and the first communication port 24, and the air inlet channel 23 is not communicated with the second air duct 21, so that the warm air provided by the air conditioning system is only blown to the sole of the foot 00 of the foot part 00 of the passenger through the first air duct 11 and the air hole 12, and the warm air is not blown to the instep of the foot part 00 of the passenger. At the same time, the power member 32 can be used to drive the moving member 31 to move to the second position, so that the moving member 31 shields the first communication port 24, at this time, the air inlet channel 23 is only communicated with the second air duct 21 through the second communication port 25, and the air inlet channel 23 is not communicated with the connecting air duct 27 and the first air duct 11, so that the warm air provided by the air conditioning system is only blown to the instep of the foot part 00 of the passenger through the second air duct 21 and the air outlet 22, and the warm air is not blown to the sole of the foot part 00 of the passenger.

[0072] It should be noted that when the power member 32 drives the moving member 31 to move to a position between the first position and the second position, the moving member 31 neither shields the second communication port 25 nor shields the first communication port 24, at this time, the warm air can be blown to the sole and the instep of the foot part 00 of the passenger at the same time, so that the warm air provided by the air conditioning system covers the sole and the instep of the foot part 00 of the passenger at the same time.

[0073] It can be understood that in combination with the air conditioning system, the ventilation device provided by the embodiment of the present application can realize the traditional instep heating ventilation function alone, can realize the sole dispersion heating ventilation function alone, and can also provide three forms of instep heating ventilation and sole dispersion heating ventilation coexistence, realize three ventilation path selections, and has various forms, simple structure, small size, flexible arrangement, and user selection and adjustment according to needs.

[0074] For example, the power member 32 can include a motor, a pneumatic cylinder or a hydraulic cylinder, etc. The moving member 31 can include a damper, etc. The power member 32 can drive the moving member 31 to move or rotate.

[0075] For example, the power member 32 can include a motor, a pneumatic cylinder or a hydraulic cylinder, etc. The moving member 31 can include a damper, etc. The power member 32 can drive the moving member 31 to move or rotate. Figure 2 Figures 5 to 10 In the embodiment, the moving member 31 is arranged in the inside of the air inlet channel 23, the moving member 31 is rotationally connected with the second connecting member 20, and the power member 32 can drive the moving member 31 to rotate relative to the second connecting member 20, so that the moving member 31 rotates to the first position or the second position.

[0076] By using the above scheme, the moving member 31 can be rotated to the first position or the second position, so as to meet different ventilation needs and blow warm air to the sole and / or the instep of the foot part 00 of the passenger.

[0077] ​Optionally, the switching mechanism 30 further comprises a rotating shaft 33 connected with the moving member 31, the power member 32 is in transmission connection with the rotating shaft 33, and an abutting end 311 is arranged at an end of the moving member 31 away from the rotating shaft 33; when the moving member 31 moves to the first position, the abutting end 311 abuts against a part of the inner wall of the air inlet channel 23 to shield the second communication port 25; when the moving member 31 moves to the second position, the abutting end 311 abuts against another part of the inner wall of the air inlet channel 23 to shield the first communication port 24.

[0078] In this way, the moving member 31 can be moved to the first position to completely shield the second communication port 25, and the moving member 31 can be moved to the first position to completely shield the first communication port 24.

[0079] Optionally, the abutting end 311 is made of soft rubber.

[0080] In this way, the sealing performance between the abutting end 311 and the inner wall of the air inlet channel 23 can be improved.

[0081] For example, the soft rubber can be rubber or silica gel. The abutting end 311 made of soft rubber can be made of soft rubber throughout, or the abutting end 311 is wrapped with soft rubber.

[0082] Optionally, the abutting end 311 comprises a plurality of tooth-shaped portions 312, and the plurality of tooth-shaped portions 312 are arranged at intervals along the axis direction of the rotating shaft 33.

[0083] In this way, the abutting end 311 can be tightly attached to the inner wall of the air inlet channel 23, and the problem that the abutting end 311 cannot be tightly attached to the inner wall of the air inlet channel 23 due to uneven surface can be solved.

[0084] Optionally, the switching mechanism 30 further comprises a limiting portion 34 connected with the rotating shaft 33, the limiting portion 34 abuts against a part of the inner wall of the second air duct 21 when the moving member 31 moves to the first position, and the limiting portion 34 abuts against a part of the inner wall of the connecting air duct 27 when the moving member 31 moves to the second position.

[0090] Optionally, the ventilation device further comprises a non-woven fabric surface layer 40, and the non-woven fabric surface layer 40 is attached to the bearing surface 13.

[0091] In this way, the low wind resistance can be achieved, and the appearance and comfort experience can be as good as possible.

[0092] It can be understood that the warm air can be blown to the soles of the feet 00 of the passenger through the first air duct 11, the orifice of the air hole 12 and the non-woven fabric surface layer 40. When the non-woven fabric surface layer 40 is covered with dust and other foreign matters for a long time, the ventilation function is affected by too much dust. The non-woven fabric surface layer 40 can be detached together with the first connecting piece 10, cleaned and dried, and then installed and used again, so that the maintenance cost is low and the non-woven fabric surface layer 40 can be repeatedly used.

[0094] In this way, the warm air in the first air duct 11 and the warm air in the second air duct 21 can be insulated, so that the energy consumption is reduced and the heat utilization rate is improved.

[0095] For example, the thermal insulation layer 50 can comprise sponge or the like.

[0096] Optionally, a plurality of separation portions 221 are arranged in the air outlet 22, and the separation portions 221 separate the air outlet 22 into a plurality of parts.
