The back of the air guide cover 3 is divided into a plurality of guide areas 33, and the plurality of guide areas 33 are arranged in a one-to-one correspondence with the plurality of fragrance chambers 61. Each guide area 33 covers a fragrance chamber 61, and the inner surface of the guide area 33 and the concave plane 612 enclose a guide cavity c; the plurality of guide port groups 31 are respectively arranged in a one-to-one correspondence on the plurality of guide areas 33; a fragrance diffusion port (71), a plurality of ventilation ports (611) of a corresponding fragrance chamber (61) and two corresponding guide ports (31a) are arranged in a one-to-one correspondence, and one of the two guide ports 31a is connected to the plurality of air inlet holes 52, and the other guide port 31a is connected to the air intake port 53, the fan, and the air outlet in sequence, and the fragrance gas is blown out of the air outlet into the air by the fan. The guide cavity c becomes a channel for the fragrance gas to circulate.

[0026] Please refer to Figure 1 、 Figure 4 、 Figure 6 and Figure 8The motor 1 drives the switching member 2 to rotate; the switching member 2 is disposed in the accommodating chamber 51 and includes a rotating shaft 21, a plurality of operating members 22, and a plurality of switching portions 22a. The plurality of switching portions 22a are spaced apart on the rotating shaft 21 and located in different directions along the circumference of the rotating shaft 21. The plurality of operating members 22 are spaced apart and sleeved on the rotating shaft 21. That is, the operating member 22 includes a connecting portion 22b and the switching portion 22a. The switching portion 22a is integrally connected to the connecting portion 22b and protrudes from the connecting portion 22b. The plurality of switching portions 22a are located in different directions along the circumference of the rotating shaft 21. The connecting portion 22b does not contact the movable valve 4. The plurality of switching parts 22a, the plurality of drainage port groups 31, the plurality of movable valves 4 and the plurality of fragrance diffusion ports (71) are arranged in a one-to-one correspondence, and each movable valve 4 blocks the two corresponding drainage ports 31a; any of the switching parts 22a can drive the corresponding movable valve 4 to move downward to open the two corresponding drainage ports 31a on the air guide cover 3, so that the corresponding two drainage ports (31a) and the corresponding fragrance diffusion ports (71) are connected. The motor 1 drives the rotating shaft 21 to rotate around its own axis. When the rotating shaft 21 rotates to different angles, the switching parts 22a of different operating members 22 on the rotating shaft 21 abut against the corresponding movable valve 4 to drive the movable valve 4 to move downward to open the drainage port 31a corresponding to the movable valve 4. When the movable valve 4 is opened, each drainage port group 31 on the air guide cover 3 is connected to a fragrance chamber 61. The connection to the closing of each drainage port group 31 and the corresponding fragrance chamber 61 corresponds to a rotation stroke of the switching member 2. In this way, the rotation stroke of the rotating shaft 21 is different, and the fragrance chamber 61 of the corresponding rotation stroke is connected to the vehicle cabin through the drainage port group 31. In this way, the user can switch the rotating shaft 21 between different rotation strokes as needed to connect different fragrance chambers 61 with the vehicle cabin, thereby providing fragrance gases with different smells into the vehicle cabin to meet the user's demand for diverse fragrance smells. When the motor 1 drives the switching member 2 to rotate to different angles, the relative position of the switching member 2 and each fragrance chamber 61 does not change, but the circumferential position of the switching portion 22a on the switching member 2 changes. When the switching portion 22a on the switching member 2 rotates to abut against the corresponding movable valve 4, as the switching member 2 continues to rotate, the switching portion 22a can drive the corresponding movable valve 4 to move downward, opening the corresponding two drainage ports 31a on the air guide cover 3. The fragrance gas in the corresponding fragrance chamber 61 is finally released into the vehicle cabin through the opened drainage port 31a, the air intake port 53, the fan, and the air outlet to improve the comfort of the user.

[0027] Please refer to Figure 1 、 Figure 4 and Figure 7-8The movable valve 4 includes two horizontal plates 41, an insert 42, a groove 44 and an elastic component 43. The two horizontal plates 41 are respectively tightly attached to the bottom surfaces of the two corresponding drainage ports 31a on the air guide cover 3; the groove 44 is connected between the two horizontal plates 41 to form an inverted "J" shape structure. The groove 44 is sleeved on the two hard edges 32, and the bottom surface of the groove 44 is provided with an opening. The insert 42 has an open end 421 and a closed end 422. The insert 42 is arranged on the groove 44, and the opening is connected to the open end 421 of the insert 42. The closed end 422 of the insert 42 is passed through the air guide cover 3, that is, the closed end 422 of the insert 42 passes through the notch 321. The notch 321 serves to position and guide the insert 42. When the movable valve 4 moves downward to a stop, the insert 42 remains in the notch 321 and will not fall out. The downward movement direction will not deviate. The insert 42 of each movable valve 4 is inserted into the accommodating cavity 51 and is positioned corresponding to a corresponding switching portion 22a. Specifically, the insert 42 is positioned below a corresponding switching portion 22a. When the switching portion 22a drives the insert 42 downward, the two horizontal plates 41 move away from the two drainage ports 31a. When the switching portion 22a leaves the insert 42, the elastic member 43 forces the insert 42 to return to its original position. The elastic member 43 is positioned within the insert 42, with the lower end of the elastic member 43 extending beyond the open end 421 of the insert 42 and abutting against the concave surface 612. A convex circle 423 is also provided on the closed end 422 of the insert 42. When the corresponding switching portion 22a of the switching member 2 rotates with the rotating shaft 21, it can apply a downward force to the convex circle 423, driving the insert 42 to move downward. There is point contact between the convex circle 423 and the switching portion 22a, and the contact surface is small. The force applied by the switching portion 22a on the convex circle 423 is larger and more concentrated, and the switching portion 22a can pass over the convex circle 423 more smoothly.

[0028] Please refer to Figure 1 and Figure 6The travel switch 9 includes a control dial 91, a photoelectric switch 92, and a PCB board (not shown). The control dial 91 is mounted on the switching member 2, and the motor 1 and the photoelectric switch 92 are electrically connected to the PCB board. The control dial 91 is movably fitted within the photoelectric switch 92. The control dial 91 is provided with a plurality of signal modules 911. Each signal module 911 includes a positioning module 911a and a judgment module 911b. The positioning module 911a is disposed adjacent to the judgment module 911b, and the judgment modules 911b in each signal module 911 are different. The judgment module 911b includes at least one short hole, and the number of short holes in each judgment module 911b is different. The positioning module 911a includes one long hole. The depth of the short hole is less than the depth of the long hole. During use, the PCB can distinguish the different operating states of the fragrance switching mechanism J through the judgment module 911b and control the fragrance switching mechanism J to execute the corresponding operating state through the positioning module 911a. Each fragrance cartridge 7 is internally equipped with an ID recognition module (not shown), and each ID recognition module is electrically connected to the PCB. Each fragrance cartridge 7 has a different fragrance. The ID recognition module is used to record the fragrance type and other fragrance ID information of the fragrance cartridge 7, making the fragrance cartridge 7 identifiable. The PCB can read the ID recognition module and send the read fragrance type and other information to the terminal display for the user to select the fragrance.

[0029] The fragrance switching structure J of the present invention has a simple structure, wherein the two horizontal plates 41 of the movable valve 4 seal the corresponding two drainage ports 31a on the air guide cover 3, and the air duct is sealed with one surface, which has a good sealing effect.
