It should also be noted that the aforementioned Z axis is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] like Figure 1 , 3 As shown in , 4, a channel switching mechanism of a fragrance device according to an embodiment of the utility model comprises a driving structure 1, a switching tube 2, a sleeve 3 and a photoelectric detection device 4, wherein the sleeve 3 is provided with a plurality of first fragrance holes 31 at intervals along the circumferential direction, each of the first fragrance holes 31 is respectively used to communicate with the corresponding fragrance module 6, one end of the switching tube 2 extends into the sleeve 3, and the end of the switching tube 2 extending into the sleeve 3 is provided with a second fragrance hole 21, the driving structure 1 is drivingly connected to the switching tube 2 to drive the switching tube 2 to rotate so that the second fragrance hole 21 is communicated with the corresponding first fragrance hole 31, the end of the switching tube 2 extending out of the sleeve 3 is provided with a light-through hole 22 along the circumferential direction, the photoelectric detection device 4 is arranged at a position along the movement stroke of the light-through hole 22, and the feedback signal recognition position of the photoelectric detection device 4 at the light-through hole 22, or the superimposed signal recognition position generated by the feedback signal and the switching tube 2 rotating the preset stroke again, corresponds to the stop position of the driving structure 1.

[0026] Specifically, the driving structure 1 can be a rotary driving motor, providing a driving force for rotation around the Z axis, the switching tube 2 can be a vertically arranged circular tube, the inner hollow of the switching tube 2 can be connected to the vehicle interior environment, the upper end of the switching tube 2 extends into the sleeve 3, the first fragrance hole 31 and the second fragrance hole 21 are arranged at substantially the same height, the shapes of the first fragrance hole 31 and the second fragrance hole 21 match, and when the switching tube 2 rotates, the second fragrance hole 21 can be selectively connected to the first fragrance hole 31. The fragrance module 6 can be a fragrance of any fragrance type, and a hole is provided thereon to emit fragrance. The lower end of the switching tube 2 can be provided with a light-through hole 22 along the circumferential direction, and the light-through hole 22 extends along the circumferential direction. The photoelectric detection device 4 can emit light along the radial direction of the switching tube 2. When the switching tube 2 rotates around its axis, the photoelectric detection device 4 can receive feedback signals from each light-through hole 22 in sequence. Here, the second fragrance hole 21 is connected to the corresponding fragrance module 6 through the corresponding first fragrance hole 31 to form a fragrance channel, and the number of the light holes 22 can be determined according to the number of the fragrance channels.

[0027] In this embodiment, when the driving structure 1 drives the switching tube 2 to rotate relative to the sleeve 3, the second fragrance hole 21 can be connected to one of the first fragrance holes 31. After the air enters the interior of the switching tube 2, it can enter the corresponding fragrance module 6 through the second fragrance hole 21 and the first fragrance hole 31 in sequence, so as to achieve different fragrance emission. At the same time, since the switching tube 2 is provided with a light hole 22 along the circumferential direction, and the photoelectric detection device 4 is located along the movement stroke of the light hole 22, the photoelectric detection device 4 can identify the feedback signal of the light hole 22. If the feedback signal recognition position of the photoelectric detection device 4 at the light hole 22 corresponds to the stop position of the driving structure 1, it means that the switching tube 2 rotates to the second fragrance hole 21 and communicates with the corresponding first fragrance hole 31, the driving structure 1 stops, and the corresponding fragrance channel is turned on; or, the feedback signal of the photoelectric detection device 4 at the light hole 22 and the superimposed signal recognition position generated by the switching tube 2 rotating again correspond to the stop position of the driving structure 1, indicating that the corresponding fragrance channel is turned on and the driving structure stops. Through the photoelectric detection device 4 and the driving structure 1, accurate adjustment of the conduction of different fragrance channels can be achieved, and the operation is more convenient. Moreover, the photoelectric detection device 4 receives the feedback signal of the light hole to stop the driving structure 1, and on the basis of the conduction of the corresponding fragrance channel, the switching tube 2 is rotated again by a preset stroke to allow other fragrance channels to be conducted. It can be achieved on the basis of setting a small number of light holes to switch more fragrance channels, simplifying the structure of the switching tube 2 and the entire channel switching mechanism.
