A ventilation and aromatherapy mechanism 200 is provided inside the car headrest 100 to blow a gentle breeze with a fragrant smell when the passenger is motion sick, thereby alleviating the body's motion sickness reaction.

[0047] Refer to Figures 1-6 , In the ventilation and aromatherapy mechanism 200, a wind guide block 201 is fixedly arranged on one side of the inner cavity of the car headrest 100, and a number of air ducts 205 penetrating the wind guide block 201 are opened in the wind guide block 201. Thus, the wind guide block 201 is used to provide a gentle breeze with a fragrant smell to the necks of the driver and passengers. A fragrance storage strip 206 is opened in the middle of the surface of the wind guide block 201 on the side of the inner cavity of the car headrest 100, and a number of different types of aromatherapy materials 202 are snap-fitted in the inner cavity of the fragrance storage strip 206. The number of aromatherapy materials 202 can select different spice fragrances such as single flavor and multi-flavors according to actual applications. The height of the fragrance storage strip 206 is the same as that of the aromatherapy material 202, thus realizing the storage of the aromatherapy material 202. The length of the fragrance storage strip 206 allows more than four aromatherapy materials 202 to be stored at the same time, but four is the best.

[0048] Refer to Figures 1-6 , An aromatherapy controller 203 is arranged on one side of the aromatherapy material 202, so that the aromatherapy controller 203 can control the fragrance emission of different types of aromatherapy materials 202, enabling the driver and passengers to smell the desired smell. A ventilation fan 204 fixedly connected to the car headrest 100 is arranged on the side of the aromatherapy controller 203 away from the aromatherapy material 202. The ventilation fan 204 can blow the gentle breeze with different smells of the aromatherapy material 202 to the driver and passengers through the air ducts 205. The ventilation fan 204 is also conducive to ventilation. The wire harness of the ventilation fan 204 is connected to the control wire harness 103 arranged on one side, and the wire harness of the aromatherapy controller 203 is also connected to the control wire harness 103, thus preventing the wire harnesses from being too many and causing chaos. The other side of the control wire harness 103 is connected to an anti-motion sickness control module 102, so that the driver and passengers can control the selection of different fragrance gases and the opening of the whole device through the anti-motion sickness control module 102. The anti-motion sickness control module 102 integrates relevant control programs inside.

[0049] Setting a ventilation fan 204 in the inner cavity of the car headrest 100 of the seat can provide a comfortable gentle breeze to the necks of the driver and passengers, and the fragrance controller 1 203 can select the fragrance material 202 suitable for the fragrance chosen by the driver and passengers. Then, the fragrance emitted by the fragrance material 202 is blown towards the driver and passengers through several air ducts 205 opened inside the air guide block 201, so as to achieve the effect of relieving the motion sickness of the driver and passengers through the gentle breeze with fragrance.

[0050] The implementation principle of an anti-motion sickness headrest with fragrance ventilation in an embodiment of this application is as follows: When the occupant feels unwell or has motion sickness, the anti-motion sickness control module 102 can control the ventilation fan 204 to make the ventilation fan 204 work. At the same time, the fragrance controller 1 203 works, and the fragrance material 202 selected by the driver and passengers emits fragrance. Then, the ventilation fan 204 blows these emitted fragrances, and then provides a gentle breeze with the fragrance suitable for the driver and passengers to their necks through the air ducts 205. Adding fragrance to the gentle breeze can relieve the body's motion sickness reaction through ventilation and smell.

[0051] Embodiment 2

[0052] Refer to Figures 7-10 In this embodiment, the difference from Embodiment 1 is that a ventilation and fragrance mechanism 2 300 is provided on one side of the inner cavity of the car headrest 100, and the ventilation and fragrance mechanism 2 300 can be used to switch between different types of fragrances, such as solid or liquid. The ventilation and fragrance mechanism 2 300 includes a fixed box 301 fixedly arranged on one side of the air guide block 201, and the fixed box 301 can be used to fixedly support the whole device. A support plate 303 is fixedly arranged in the middle of the inner cavity of the fixed box 301, and several identically structured fragrance storage bins 310 are opened in the support plate 303. The support plate 303 and the fragrance storage bins 310 cooperate with each other so that several fragrance bottles 308 can move stably in the fragrance storage bins 310. A limiting ring 312 is fixedly arranged on the inner ring surface of the fragrance storage bin 310 on the side far from the fragrance bottle 308, and a return spring 2 313 is fixedly arranged on the side of the limiting ring 312 where the fragrance bottle 308 is located. The side of the return spring 2 313 far from the limiting ring 312 is fixedly connected to the surface of one side of the fragrance bottle 308, and the return spring 2 313 can help the fragrance bottle 308 moved outside the fragrance storage bin 310 to reset.

[0053] Refer to Figures 7-10, and on the upper and lower side walls of the support plate 303 where the fixed box 301 is located, air guide openings 315 with the same structure are provided, and the air guide openings 315 are in communication with the inner cavity of the air guide duct 205. Thus, the ventilation fan 204 can blow the fragrance into the air guide duct 205 through the air guide openings 315. In the middle of the side of the fixed box 301 away from the support plate 303, a fixed bin 302 is fixedly arranged, and the fixed bin 302 can be inserted with the fragrance storage strip 206. In the middle of one side of the inner cavity of the fixed bin 302, it is rotatably arranged with the rotating shaft 304, and at one end passing through the fixed bin 302 and the car headrest 100, it is fixedly connected with the knob 307. The knob 307 can be used to select and switch different scented fragrances. Thus, by rotating the knob 307, the several push plates 305 fixedly arranged on the outer ring surface of the rotating shaft 304 can be rotated.

[0054] Refer to Figures 7-10 , and the several push plates 305 are arranged at intervals on the outer ring surface of the rotating shaft 304, and the several push plates 305 are arranged at different angles. Thus, intermittent movement can be achieved. When the several push plates 305 rotate intermittently, they can abut against several folding connecting rods 306 arranged on one side in the aromatherapy bin 310. Thus, when one push plate 305 abuts against one folding connecting rod 306, it can push the folding connecting rod 306 to move in the aromatherapy bin 310, so that the fragrance bottle 308 fixedly connected to the side of the folding connecting rod 306 away from the push plate 305 can be pushed out of the aromatherapy bin 310, so that the fragrance bottle 308 can abut against the fragrance controller two 317 fixedly arranged on the upper part of the fragrance controller one 203. Thus, as the rotating shaft 304 pushes the folding connecting rods 306 one by one, the several fragrance bottles 308 filled with different scents can be pushed out of the aromatherapy bin 310 one by one. Thus, the purpose of switching different types of fragrances can be achieved.

[0055] Refer to Figures 7-10 , and on one side of the folding connecting rod 306, one end of a first return spring 311 is fixedly connected, and the end of the first return spring 311 away from the folding connecting rod 306 is fixedly connected to the inner wall of the aromatherapy bin 310. Thus, the first return spring 311 can be reset after the folding connecting rod 306 is pushed by the push plate 305 to rotate. On the side of the fragrance bottle 308 away from the push plate 305, it is set as the bottle mouth of the fragrance bottle 308. When loading the liquid aromatherapy 202, a rubber stopper 309 made of butyl rubber material can be installed at the bottle mouth of the fragrance bottle 308. Thus, the rubber stopper 309 can seal the liquid fragrance, and a volatilization rod 318 is installed in the middle of one side surface of the fragrance controller two 317 for cooperation, so that the volatilization rod 318 is inserted into the rubber stopper 309 and then contacts and absorbs the liquid aromatherapy 202 in the fragrance bottle 308. Thus, the aromatherapy 202 is volatilized, and the ventilation fan 204 can blow the volatilized aromatherapy 202 into the air guide opening 315.

[0056] Reference Figures 7-10 When using the solid fragrance 202, the rubber stopper 309 and the wick 318 can be removed, and the sealing cover 314 provided on the side of the rubber stopper 309 away from the fragrance bottle 308 is used. The sealing cover 314 is fixedly connected to the surface of one side of the support plate 303, and the diameter of the sealing cover 314 is the same as the diameter of the fragrance chamber 310, and can seal the fragrance chamber 310, thereby realizing the sealing of the solid fragrance 202, preventing the odor of the multi-flavored fragrance 202 from overflowing, and thus causing the mixing of flavors, which will instead increase the phenomenon of motion sickness of personnel.

[0057] Reference Figures 7-10 On the bottom surface of one side of the inner cavity of the fixed box 301, a hinge base 316 is fixedly provided. The upper part of the hinge base 316 is fixedly connected to the first fragrance controller 203, and the upper part of the first fragrance controller 203 is fixedly connected to the second fragrance controller 317. One side surface of the second fragrance controller 317 is attached to the pushed-out fragrance bottle 308. When the fragrance bottle 308 is pushed out, it will push open the sealing cover 314. At this time, due to the distance, the sealing cover 314 will push the second fragrance controller 317, and then the first fragrance controller 203 and the hinge base 316 will follow the hinge base 316 to flip when receiving the thrust of the sealing cover 314, so that the sealing cover 314 is opened, and the second fragrance controller 317 follows the hinge base 316 to reset and abuts against the fragrance bottle 308.

[0058] The fixed box 301 is fixedly connected to the fragrance 202, so that the inner cavity of the air guide port 315 opened in the fixed box 301 can be attached to and communicate with the inner cavity of the air guide duct 205, so that the ventilation fan 204 can blow out the fragrance gas emitted from the fragrance bottle 308 in the fixed box 301 through the air guide port 315 and the air guide duct 205. By rotating the knob 307, the rotating shaft 304 drives the push plate 305 to rotate, so that the plurality of push plates 305 arranged at intervals and at different angles will abut against their respective corresponding folding connecting rods 306 one by one during the rotation process. Therefore, only one of the plurality of folding connecting rods 306 arranged at intervals will push out the fragrance bottle 308 from the inner cavity of the fragrance chamber 310 each time, push open the sealing cover 314, and then abut against the second fragrance controller 317, thereby releasing the fragrance, so as to achieve the selection of fragrances with different flavors according to personal preferences.

[0059] By installing a rubber stopper 309 at the opening of the fragrance bottle 308, the fragrance bottle 308 can be sealed, so that a liquid fragrance can be added to the fragrance bottle 308. Then, by cooperating with the volatilization rod 318 installed on the surface of the second fragrance controller 317, when the fragrance bottle 308 abuts against the second fragrance controller 317, the volatilization rod 318 will pass through the rubber stopper 309 and enter the fragrance bottle 308, thereby volatilizing the gas in the fragrance bottle 308, realizing the switching between the liquid fragrance 202 and the solid fragrance 202, and increasing more selectivity.

[0060] The implementation principle of Embodiment 2 is as follows: When the driver or passenger feels discomfort or carsickness, the anti-motion sickness control module 102 controls the ventilation fan 204, the first fragrance controller 203, and the second fragrance controller 317 to work. At the same time, turn the knob 307 to select the smell of the fragrance 202 you like. Then, the knob 307 drives the push plate 305 to rotate. However, when the push plates 305 arranged at several intervals and different angles rotate, they will successively abut against their corresponding folding connecting rods 306 one by one. As a result, only one fragrance bottle 308 will be pushed out of the inner cavity of the fragrance bin 310 by the several folding connecting rods 306 arranged at intervals each time. When it is pushed out, the sealing cover 314 will be pushed open, and then it will abut against the second fragrance controller 317. Then, the ventilation fan 204 blows the fragrance through the air guide port 315 and the inner cavity of the air guide duct 205 towards the necks of the driver and passenger, thereby relieving the carsickness reaction of the human body by ventilation and selecting a suitable smell for oneself.

[0061] The above are only optional embodiments of the present disclosure and are not used to limit the present disclosure. For those skilled in the art, various changes and modifications can be made to the present disclosure.
