Technical Field

[0001] This utility model relates to the field of automotive fragrance devices, and more specifically, to a fragrance device for automotive air conditioning vents. Background Technology

[0002] With the continuous development of the automotive industry, the in-car driving environment has become an increasingly important topic of public concern and a key factor for consumers when buying a car. A comfortable driving environment can reduce driver fatigue, stabilize driving emotions, and enhance driving pleasure. Therefore, more and more cars are now equipped with in-car fragrance systems, which can provide a pleasant aroma to the interior and improve the driving experience for passengers. However, existing fragrance systems in cars are all independent structures, typically placed on the center console or armrest, thus taking up interior space. Furthermore, the fragrance they produce is difficult to diffuse throughout the cabin, resulting in limited aroma diffusion. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a fragrance device for car air conditioning vents, which can avoid the fragrance device occupying the space inside the car and can improve the fragrance diffusion capacity and effectiveness of the fragrance device.

[0017] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] See Figures 1-7As shown in the figure, this application discloses an air vent fragrance device for automobiles, including an air vent trim 1, a fragrance box 2, a fragrance selection mechanism, and a fragrance delivery mechanism. The air vent trim 1 has a front-opening mounting cavity 11, and the fragrance box 2 is detachably inserted into the mounting cavity 11. The inner side of the fragrance box 2 has several slots 21 for inserting fragrance cores 3 with different scents. The fragrance selection mechanism is connected to the rear side of the air vent trim 1. The fragrance selection mechanism has several fragrance inlets and a fragrance outlet. The fragrance inlets are respectively connected to the inner cavity of one of the slots. The fragrance selection mechanism is used to deliver the fragrance diffused by the corresponding fragrance core 3 to the inlet end of the fragrance delivery mechanism according to the user's selection. The fragrance delivery mechanism is used to deliver the fragrance from the fragrance selection mechanism to the air vent 12 located on the air vent trim 1.

[0019] Each slot 21 has a diffuser hole group 22 at its bottom, and the mounting cavity 11 has a fragrance guide hole group 13 corresponding to each diffuser hole group 22 at its bottom. When the fragrance box 2 is inserted into the mounting cavity 11, each diffuser hole group 22 is connected to the corresponding fragrance guide hole group 13. With this structure, when the fragrance box is inserted into the mounting cavity, each diffuser hole group can be connected to the corresponding fragrance guide hole group, so that the fragrance generated by the fragrance core in each slot can be reliably diffused from the corresponding fragrance guide hole group to the corresponding fragrance inlet on the fragrance selection mechanism.

[0020] The rear end of the fragrance box 2 is provided with a locking hook 23, and the rear end of the mounting cavity 11 is fixed with a push-type lock 4. When the fragrance box 2 is inserted into the mounting cavity 11, the locking hook 23 and the push-type lock 4 are engaged to lock the fragrance box 2 to the air conditioner vent trim 1. With this structure, after the fragrance box is inserted into the mounting cavity, the locking hook can engage with the push-type lock, and at this time, the fragrance box can be locked to the air conditioner vent trim. When the fragrance box is pushed again, the push-type lock can unlock from the locking hook, and at this time, the fragrance box can be pulled out from the mounting cavity. The push-type lock mentioned above is the existing technology on the market, so it will not be described in detail here.

[0021] The outer wall of the fragrance box 2 is provided with several raised ribs 24 in a circumferential direction. Each raised rib 24 extends along the insertion direction between the fragrance box 2 and the mounting cavity 11. The raised ribs 24 are used to abut against the inner wall of the mounting cavity 11. After several raised ribs are provided in a circumferential direction on the outer wall of the fragrance box, when the fragrance box is inserted into the mounting cavity, the raised ribs can abut against the inner wall of the mounting cavity, thereby reducing the contact area between the fragrance box and the mounting cavity, that is, reducing the friction, and thus making it easier to assemble the fragrance box into the mounting cavity or remove the fragrance box from the mounting cavity.

[0022] The fragrance selection mechanism includes a stepper motor 5, a valve body 6, and a valve core 7. Both the stepper motor 5 and the valve body 6 are fixed to the air conditioning vent trim 1. The valve core 7 is rotatably connected to the inner side of the valve body 6. Several through-hole groups 61 are circumferentially arranged on the side wall of the valve body 6. Each through-hole group 61 forms one of the fragrance inlets of the fragrance selection mechanism. The several through-hole groups 61 are respectively connected to one of the fragrance guide hole groups 13 or connected via a connector 62. A fragrance outlet hole 63 is provided on the valve body 6, forming the fragrance outlet of the fragrance selection mechanism. The valve core 7 is a hollow structure with one open end. A fragrance inlet group 71 is provided on the side wall of the valve core 7. The inner cavity of the valve core 7 communicates with the fragrance outlet hole 63 through the opening at one end of the valve core 7. The other end of the valve core 7 is connected to the stepper motor 5. The output shaft of motor 5 is fixed coaxially. When stepper motor 5 drives valve core 7 to rotate relative to valve body 6, the fragrance inlet group 71 is used to alternately connect with one of the through-hole groups 61. By adopting this fragrance selection mechanism, when stepper motor drives valve core to rotate relative to valve body, fragrance inlet group can alternately connect with one of the through-hole groups. When fragrance inlet group connects with one of the through-hole groups, the fragrance from the corresponding through-hole group can enter the valve core and be discharged through the fragrance outlet. When stepper motor drives valve core to rotate relative to valve body by a certain angle again, fragrance inlet group can connect with another through-hole group. At this time, fragrance from the corresponding through-hole group can enter the valve core and be discharged through the fragrance outlet, thereby realizing the selection of fragrance scent.

[0023] In this embodiment, the fragrance box has three slots, and correspondingly, three fragrance cores are also provided. The three fragrance cores are inserted into different slots. Similarly, there are also three groups of fragrance guide holes and three groups of through holes. The through hole group located in the middle is directly connected to the fragrance guide hole group located in the middle, and the through hole groups located on both sides are connected to the corresponding fragrance guide hole groups through connectors.

[0024] The outer peripheral wall of the valve core 7 is in contact with the inner peripheral wall of the valve body 6. By adopting this method, the coaxiality of the valve core can be guaranteed when the valve core rotates relative to the valve body. At the same time, it can prevent the aromas from different through-hole groups from mixing through the gap between the valve core and the valve body.

[0025] A limit block 72 is provided on the outer wall of the valve core 7, and a stop block 64 is provided on the end of the valve body 6. The stop block 64 is used to abut against the limit block 72 to limit the rotation angle range of the valve core 7. With this structure, when the valve core rotates relative to the valve body, the rotation angle range of the valve core relative to the valve body can be limited under the limiting action of the limit block and the stop block, so as to avoid the valve core from rotating excessively relative to the valve body.

[0026] The fragrance delivery mechanism includes a fan 8 and a fragrance guide tube 9. The fan 8 is fixed on the air conditioning vent trim 1, and the air inlet of the fan 8 faces the fragrance outlet of the fragrance selection mechanism. A fragrance inlet 14 is provided on one side of the air conditioning vent 12, and the fragrance inlet 14 is connected to the air outlet of the fan 8 through the fragrance guide tube 9. With this structure, when the fan is working, it can draw in the fragrance discharged from the fragrance outlet of the fragrance selection mechanism and send the fragrance into the air conditioning vent through the fragrance guide tube, so that the fragrance can mix with the air blown out by the car air conditioning and diffuse into the car body. In addition, by controlling the speed of the fan, the amount of fragrance drawn by the fan from the fragrance selection mechanism can be controlled, that is, the amount of fragrance delivered by the fragrance delivery mechanism to the fragrance guide tube and the air conditioning vent can be changed, thereby controlling the fragrance concentration in the car.

[0027] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
