[0002] With the development and progress of society, consumers have an increasing trend in the user experience of products. Based on this, in-vehicle fragrance devices have begun to be provided on some vehicles, which are used to release gases with specific smells into the air in the vehicle cabin to make the vehicle driver and passengers feel more comfortable.

[0003] The Chinese utility model patent with the publication number of CN214450160U discloses a fragrance device. The air door assembly of the fragrance device is composed of an air door, a push rod and an elastic member. The air door includes a front air door and a rear air door, and the front air door and the rear air door are respectively arranged corresponding to the front air outlet and the rear air outlet. The push rod is arranged in the front-rear direction, and the air door is arranged on the push rod and can move back and forth with the push rod, so that the cam can push the push rod backward to open the air door; the front air door and the rear air door are arranged one in front of the other, and are respectively used to cover the front air outlet and the rear air outlet to close the front and rear ends of the fragrance channel; the elastic member can make the push rod move forward. When the cam pushes the push rod backward, the elastic member is compressed and stores energy. When the cam releases the push rod, the push rod moves forward under the elastic force of the elastic member and returns to its original position to close the air door. However, the above air door structure is complex in the assembly process, and it is necessary to assemble two sliding rods and sliding holes, and the required components are more, which increases the cost.

[0004] The Chinese invention patent with the publication number of CN112895852B discloses an in-vehicle fragrance generator and an in-vehicle fragrance system. The air door of the in-vehicle fragrance generator is composed of a first door body and a second door body. The first door body is arranged corresponding to the first channel opening to open or close the first channel opening; the second door body is arranged corresponding to the second channel opening to open or close the second channel opening. The first door body and the second door body are fixedly connected into an integrated structure through an intermediate connecting frame. In this way, the first door body and the second door body in the same air door can be linked through the intermediate connecting frame, so that the first door body and the second door body can be opened or closed simultaneously. However, in order to better realize the stability of the air door assembly during movement, a moving guide post is arranged on the outer side of the first door body, a reset guide post is arranged on the outer side of the second door body, and the air door is reset through a guide sleeve and a spring. The structure is also complex and there are many components, which not only increases the cost, but also makes the assembly process complex.

[0005] The Chinese invention patent with the publication number CN110143116B discloses an integrated vehicle-mounted fragrance assembly, wherein a push rod is respectively arranged in each fragrance box of the vehicle-mounted fragrance assembly, an air inlet baffle is fixed at one end of the push rod, and an air outlet baffle is fixed at the other end, and one end of the push rod with the air outlet baffle is respectively extended into a push rod hole, and a reset device for resetting each push rod is also arranged on the housing, and the controller controls the propulsion device according to the user's instruction, so that the propulsion device pushes a push rod to move from the air inlet of the fragrance box to the air outlet, so that the air inlet and the air outlet of a fragrance box are opened, and the air flow enters the fragrance box, and the fragrance selected by the user is emitted from the fragrance box, and the propulsion device stops propulsion, and under the action of the reset device, the push rod is reset, and the air inlet baffle and the air outlet baffle respectively close the air inlet and the air outlet of the fragrance box. However, a sliding rod extending in a direction away from each other is provided on the side where the two dampers deviate from each other, and the sliding rod cooperates with the sliding hole to realize the movement of the restrained damper. The assembly process is complicated and the cost is increased. Utility Model Content

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0039] In the description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can also be the communication inside two elements. It can be a wireless connection or a wired connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0040] Please refer to Figures 1 - 18 As shown, an embodiment of the present utility model provides an aroma generator, which includes a damper housing 400, a damper assembly 500 and a guiding structure, wherein:

[0041] The damper housing 400 has two opposite wall surfaces 410 and a peripheral wall surface 420 located between the two opposite wall surfaces, and the peripheral wall surface 420 is connected to the edges of the two opposite wall surfaces 410; a first opening 411 and a second opening 412 with the same central axis are respectively formed on the two opposite wall surfaces 410, and a mixing space communicating with both the first opening 411 and the second opening 412 is provided inside the damper housing 400.

[0042] The damper assembly 500 includes a first door panel 510, a second door panel 520, and a connecting member 530. The first door panel 510 is adapted to block the first opening 411, the second door panel 520 is adapted to block the second opening 412, the connecting member 530 is connected to both sides of the first door panel 510 and the second door panel 520, and the first door panel 510 is located inside the damper housing 400, and the second door panel 520 is located outside the damper housing 400.

[0043] The guiding structure is formed by or fixed to the connecting member 530; wherein, the guiding structure is located between the first door panel 510 and the second door panel 520, and the guiding structure cooperates with the peripheral wall surface 420 to enable the first door panel 510 and the second door panel 520 to reciprocate relative to the damper housing 400 only along the central axis.

[0044] It should be explained here that the two opposite wall surfaces 410 are two relatively parallel inner wall surfaces inside the damper housing 400, and the peripheral wall surface 420 is the wall surface on the side close to each other for connecting the two opposite inner wall surfaces. Both the first opening 411 and the second opening 412 are gas flow ports for the damper housing 400 to communicate with the outside.

[0045] Specifically, the fragrance generator in the present utility model includes an air door housing 400, an air door assembly 500, and a guiding structure. The interior of the air door housing 400 constitutes a mixing space of the gas flow channel. The air door housing 400 has two oppositely arranged wall surfaces and a peripheral wall surface 420 located between the two opposite wall surfaces 410. The peripheral wall surface 420 is connected to the edges of the two opposite wall surfaces 410 to form an accommodation space, which can be used to install the air door assembly 500 and the guiding structure. To connect to the external gas flow channel, a first opening 411 and a second opening 412 with the same central axis are respectively provided on the two opposite wall surfaces 410. One opening serves as the gas inlet port, and the other serves as the gas outlet port. The internal mixing space of the air door housing 400 can mix the fragrance of the fragrance cartridge with the air. To facilitate the control of the switch for mixing the fragrance of the fragrance cartridge with the air, the air door assembly 500 is composed of a first door panel 510, a second door panel 520, and a connecting member 530. The first door panel 510 is adapted to block or open the first opening 411, the second door panel 520 is adapted to block or open the second opening 412, and the connecting member 530 is connected between the first door panel 510 and the second door panel 520, thereby realizing the synchronous movement of the first door panel 510 and the second door panel 520. Additionally, to reduce the number of components, reduce the assembly cost, and ensure the stability and reliability of the air door assembly 500, a guiding structure is further provided between the air door housing 400 and the air door assembly 500. The guiding structure is formed by the connecting member 530 or fixed to the connecting member 530, and the guiding structure is connected between the first door panel 510 and the second door panel 520. The guiding structure itself also has a guiding and limiting function, enabling the guiding structure to cooperate with the peripheral wall surface 420 of the air door housing 400, so that the first door panel 510 and the second door panel 520 can only reciprocate along the central axis to realize the opening and closing of the first opening 411 and the second opening 412. Thus, after assembling the air door assembly 500 and the air door housing 400, the cooperation between the guiding structure and the peripheral wall surface can be completed simultaneously, so as to utilize the guiding structure to ensure the stability of the air door assembly 500 during movement. Therefore, compared with the prior art, at least one slide bar can be omitted, thereby reducing at least some of the steps during the assembly of the slide bar and reducing the assembly cost.

[0046] It should be specifically noted that Figure 1 In the illustrated embodiment, three integrally connected air door housings 400 are provided. Of course, it can also be two, or four, five, etc., which is not limited herein. The number of fragrance channels can be increased or decreased according to needs. When there are three air door housings 400, there are also three air door assemblies 500. Different fragrance cartridges 300 with different fragrances can be placed in the three different fragrance channels. By switching the opening of different fragrance channels, different fragrances can flow out from the fragrance outlet, realizing the switching of fragrances.

[0047] Further, please refer to Figure 1As shown, in an embodiment of the present utility model, the guiding structure is a rib 531 connected to the connecting member 530. A rib groove 421 is formed on the peripheral wall surface 420 of the damper housing 400, and the rib 531 is adapted to slide within the rib groove 421.

[0048] Thus, through the mutual cooperation of the rib 531 and the rib groove 421, the damper assembly 500 is circumferentially limited within the damper housing 400 (i.e., it can only move in the Z-axis direction in the attached Figure 1 ), ensuring that the damper assembly 500 does not skew during vertical movement.

[0049] In another embodiment of the present utility model, the guiding structure is a rib 531 connected to the peripheral wall surface 420 of the damper housing 400. At this time, a rib groove 421 is formed on the corresponding connecting member 530, and the rib 531 is adapted to slide within the rib groove 421, which can also ensure that the damper assembly 500 does not skew during vertical movement.

[0050] Furthermore, in an embodiment of the present utility model, the guiding structure is a cylindrical object formed by the connecting member 530, and the cylindrical object matches the inner side of the peripheral wall surface 420 of the damper housing 400; a third opening 422 is formed on the peripheral wall surface 420 of the damper housing 400, and the third opening 422 is adapted to install the aroma bomb 300. A fourth opening 532 corresponding to the position of the third opening 422 is provided on the guiding structure, and the fourth opening 532 is used for inserting the aroma bomb 300 into the guiding structure, and the fourth opening 532 is configured to have a preset length in the direction along the central axis to avoid the aroma bomb 300 when the damper assembly 500 moves.

[0051] Specifically, the cylindrical object is formed by the connecting member 530, which can be a cylindrical structure, a triangular prism structure, a polygonal structure, etc. At this time, to ensure the guiding movement between the cylindrical object and the damper housing 400, it is only necessary for the cylindrical object to match the inner side of the peripheral wall surface 420 of the damper housing 400. For example, when the cylindrical object is a cylindrical structure, the corresponding peripheral wall surface 420 of the damper housing 400 is also set as an arc-shaped structure; when the cylindrical object is a cube structure, the corresponding peripheral wall surface 420 of the damper housing 400 is also set as relatively parallel walls.

[0052] In addition, in this embodiment, when the inside of the air door housing 400 is to accommodate and install the fragrance bomb 300, a third opening 422 needs to be formed on the peripheral wall surface 420 of the air door housing 400, and a fourth opening 532 is formed on the guiding structure. The position of the fourth opening 532 corresponds to that of the third opening 422. The fragrance bomb 300 can be installed in the air door assembly 500 through the third opening 422 and the fourth opening 532, and the fragrance bomb 300 can be installed inside the mixing space through the third opening 422. In this way, the air passing through the mixing space can have a fragrance.

[0053] In other embodiments, the fragrance bomb 300 can be placed outside the mixing space but near the third opening 422. In this way, the fragrance released by the fragrance bomb 300 can diffuse into the mixing space through the third opening 422 by itself. In this way, the air passing through the mixing space can also have a fragrance.

[0054] In still other embodiments, one of the first opening 411 and the second opening 412 is an inlet, and the other is an outlet. The fragrance bomb 300 can be placed outside the mixing space but near the inlet. In this way, the fragrance released by the fragrance bomb 300 can diffuse into the mixing space through the inlet by itself. In this way, the air passing through the mixing space can also have a fragrance, and at this time, the air enters the mixing space from the third opening 422.

[0055] Further, please refer to Figure 10 、 11 As shown in FIGS. 13, in an embodiment of the present invention, the fragrance generator further includes an air door driving structure 600. The air door driving structure 600 is located outside the air door housing 400. The air door driving structure 600 and the air door assembly 500 are configured to: when directly or indirectly abutting against one of the first door panel 510 and the second door panel 520, open or close the first opening 411 and the second opening 412 simultaneously.

[0056] In one embodiment, when the air door driving structure 600 is located outside the air door housing 400, at this time, the air door driving structure 600 can directly or indirectly abut against one of the first door panel 510 and the second door panel 520, so as to drive the first opening 411 and the second opening 412 to open simultaneously.

[0057] In another embodiment, when the air door driving structure 600 needs to close the first opening 411 and the second opening 412 simultaneously, at this time, the air door driving structure 600 and the reset structure exchange positions, and then the air door driving structure 600 always abuts against the air door assembly 500. For example, when the long axis of the cam abuts, the air door is closed (corresponding to the spring being in a compressed state); when the short axis of the cam abuts, the air door is opened (corresponding to the spring recovering part of its deformation).

[0058] Thus, through the action of the air damper driving structure 600, the air damper assembly 500 is driven to open and close the first opening 411 and the second opening 412, so as to realize the opening and closing of the fragrance channel.

[0059] In another embodiment of the present utility model, the fragrance generator further includes a reset structure, and the reset structure is connected to the first door panel 510 or the second door panel 520. The reset structure is configured to: after the first door panel 510 and the second door panel 520 are moved to open or close the first opening 411 and the second opening 412, reset the first door panel 510 and the second door panel 520 to simultaneously close or open the first opening 411 and the second opening 412.

[0060] Thus, by arranging the reset structure on both sides of the air damper assembly 500, after the air damper driving structure 600 drives the air damper assembly 500 to move, the reset structure can have the power to drive the air damper assembly 500 to return to its original position. Subsequently, when the air damper driving structure 600 does not drive the air damper assembly 500, the reset structure helps the air damper assembly 500 to reset.

[0061] Furthermore, in an embodiment of the present utility model, the air damper driving structure 600 includes a gear and a rack that are in transmission connection. A convex portion is provided on the side of the rack facing away from the gear, and the convex portion is configured to be able to abut against one of the first door panel 510 and the second door panel 520 under the movement of the rack to simultaneously open or close the first opening 411 and the second opening 412.

[0062] In some other embodiments, the air damper driving structure 600 can also be set as a crank-slider structure, and through the cyclic reciprocating periodic motion, the opening and closing of the first opening 411 and the second opening 412 are realized.

[0063] In another embodiment of the present utility model, the reset structure is an elastic member. The reset of the air damper assembly 500 is realized through the elastic member.

[0064] Furthermore, please refer to Figure 1 As shown, the air damper driving structure 600 includes a rotating shaft 610 and a cam 620, wherein:

[0065] The rotating shaft 610 is arranged along a direction perpendicular to the central axis; the cam 620 is arranged on the rotating shaft 610, and the cam 620 corresponds to the position of the first opening 411 or the second opening 412. When the rotating shaft 610 rotates to different angles, the cam 620 can push the corresponding first door panel 510 or the second door panel 520 to open or close the first opening 411 and the second opening 412 on the air damper housing 400.

[0066] In addition, please refer to Figure 14 、 15, as shown in FIG. 16, the air door driving structure 600 further includes a cut aroma chamber 630 sleeved outside the rotating shaft 610 and the cam 620. The cut aroma chamber 630 is installed at a position close to the first opening 411. A cut aroma port is provided at the position where the cut aroma chamber 630 faces the first opening 411. When the cam 620 rotates a certain angle, it exactly completely blocks the cut aroma port. When rotating to other angles, it partially opens the cut aroma port and contacts the first door panel 510 or the second door panel 520. Continuing to rotate the angle, it is completely located inside the cut aroma chamber 630 to completely open the cut aroma port.

[0067] Specifically, in one embodiment, the cam 620 is provided on the rotating shaft 610. When the position of the cam 620 corresponds to the first opening 411, when the rotating shaft 610 rotates to different angles under the action of an external force, the cam 620 can push the corresponding first door panel 510 to move inside the air door housing 400. Since the first door panel 510 and the second door panel are connected together by a connecting member 530, and the connecting member 530 cooperates with the peripheral wall surface 420 of the air door housing 400, the first opening 411 and the second opening 412 on the air door housing 400 can be opened.

[0068] When both the air door housing 400 and the air door assembly 500 are three, the corresponding cams 620 are also three. Since multiple fragrance channels are arranged in sequence in the vertical direction (i.e., the Z-axis direction in the attached Figure 1 ), only a rotating shaft 610 arranged in the horizontal direction (i.e., the X-axis direction in the attached Figure 1 ) can be used to control multiple cams 620, so as to realize the opening and closing of multiple fragrance channels.

[0069] In another embodiment, the cam 620 is provided on the rotating shaft 610. When the position of the cam 620 corresponds to the second opening 412, at this time the air door driving structure 600 is located directly below the second door panel 520. The second door panel 520 is arranged inside the air door housing 400. When the rotating shaft 610 rotates to different angles, the cam 620 can push the corresponding second door panel 520 to move inside the air door housing 400, so as to open the first opening 411 and the second opening 412 on the air door housing 400.

[0070] It should be specifically noted that a cam 620 is designed on the rotating shaft 610. The cams 620 respectively correspond to different air door assemblies 500 (i.e., corresponding to different fragrance bombs 300). The radial angles between each cam 620 are different. When the rotating shaft 610 rotates to a certain angle, it will push open the first guiding column 511 on one of the air door assemblies 500, and at the same time start air extraction or air suction to take out the fragrance in the fragrance bomb 300. When the cam 620 rotates and does not contact the first guiding column 511, the air door assembly 500 closes the first opening 411 and the second opening 412, and the sealing structure of the air door assembly 500 ensures that the fragrance will not escape. By driving the rotating shaft 610 to rotate at different angles, the opening and closing of multiple fragrance bombs 300 are realized, so as to realize the switching of different fragrance types.

[0071] In one embodiment, the reset structure is an elastic member. The elastic member is connected between the inner wall of the front shell 110 and the second door panel 520. When the first opening 411 and the second opening 412 are opened, the elastic member is compressed and stores energy at this time. When the elastic member wants to recover its elastic deformation, it can make the second door panel 520 have a tendency to move in the direction of closing the air door. As Figure 1 In the shown embodiment, the elastic member can make the second door panel 520 move upward to return to its original position, press the second door panel 520 against the second opening, and at the same time the first door panel 510 presses against the first opening 411. At this time, the first opening 411 and the second opening 412 are in a closed state.

[0072] In another embodiment, for example, in the Chinese utility model patent with the publication number CN214822492U, a sliding guiding part can be provided on the cam 620, and a protrusion is provided on the air door assembly 500. Through the cooperation of the protrusion and the sliding guiding part, the movement of the air door assembly 500 is realized, and then the opening or closing of the first opening 411 and the second opening 412 is realized.

[0073] Further, please refer to Figure 2 、 4 Figures 8 and 9 as shown. In this embodiment, preferably, the elastic member is a conical spring 700.

[0074] When the elastic member adopts a conical spring 700, since when the conical spring is compressed, the large-diameter end of the conical spring 700 does not move, and the small-diameter end of the conical spring 700 moves towards the large-diameter end, the characteristics of the large and small ends of the conical spring can be utilized, that is, the large-diameter end of the conical spring 700 will not deviate during movement, to further improve the reliability during the movement of the air door assembly.

[0075] In some other embodiments, the elastic member can also be a spring. In this case, to ensure that the spring does not deviate during movement, the spring is generally sleeved on a push rod, and the push rod is connected to the bottom of the second door panel 520, so that the spring is guided by the push rod to avoid deformation of the spring. Compared with the tower spring 700, using a spring will add the use of a push rod, which not only increases the number of parts and raises the cost, but also increases the complexity of the installation process.

[0076] It can be understood that the elastic member can also be other ejection devices, as long as it can have a device with stable deformation recovery.

[0077] Further, please refer to Figure 2 、 4 As shown in FIGS. 8 and 9, the large end of the tower spring 700 is fixedly connected to the inner wall of the fragrance generator housing 100, and the small end of the tower spring 700 is connected to the surface of the first door panel 510 or the second door panel 520 facing the opposite wall surface of the fragrance generator housing 100. A damper housing 400, a damper assembly 500 and a guiding structure are provided in the fragrance generator housing 100.

[0078] Specifically in this embodiment, the large end of the tower spring 700 is fixedly connected to the inner wall of the front shell 110 of the fragrance generator housing 100, and the small end of the tower spring 700 is connected to the bottom of the second door panel 520, that is, the tower spring 700 is arranged in the vertical direction. Through the action of the tower spring 700, the second door panel 520 is pushed to close the second opening 412.

[0079] In some other embodiments, the large end of the tower spring 700 is fixedly connected to the inner wall of the front shell 110 of the fragrance generator housing 100, and the small end of the tower spring 700 is connected to the first door panel 510. Through the action of the tower spring 700, the first door panel 510 is pushed to close the first opening 411.

[0080] Further, in some embodiments, a clamping post 521 is provided on the surface of the first door panel 510 or the second door panel 520 facing the opposite wall surface 410 of the fragrance generator housing 100, and the small end of the tower spring 700 is adapted to be clamped on the clamping post 521; the clamping post 521 is cross-shaped.

[0081] Please refer to Figure 9 As shown in the figure, specifically in this embodiment, a clamping post 521 is provided on the surface of the second door panel 520 facing the inner wall surface of the fragrance generator housing 100, and the small end of the tower spring 700 is adapted to be clamped on the clamping post 521. The clamping post 521 is connected to the center position of the lower bottom of the second door panel 520, and the diameter of the clamping post 521 matches the diameter of the small end of the tower spring 700, so that the small end of the tower spring 700 can be exactly clamped on the clamping post 521, playing a positioning role for the small end of the tower spring 700.

[0082] It can be understood that the structural shape of the clamping column 521 in this embodiment is a cross-shaped structure. Of course, the clamping column can also be set to a regular triangle, a cylinder, a prism-shaped structure, etc. as needed, and the clamping column can be adapted to the inner diameter shape of the small end of the tower spring 700 to limit the small end of the tower spring 700.

[0083] For further information, see Figure 9 , 12 As shown, the fragrance generator housing 100 includes a face shell 110 and a rear shell 120 suitable for snapping onto the opening of the face shell 110, the large end of the tower spring 700 is suitable for abutting against the inner wall of the face shell 110, and a limiting plate 710 is also provided on the inner wall of the face shell 110 near the tower spring 700, the limiting plate 710 is located on both sides of the tower spring 700 in the snapping direction of the rear shell 120 and on the rear side away from the snapping direction of the rear shell 120.

[0084] Specifically in this embodiment, since the fragrance generator housing 100 is composed of a front shell 110 and a rear shell 120, the front shell 110 and the rear shell 120 are both provided with openings on the opposite sides of the fastening, wherein the front shell 110 in this embodiment needs to accommodate the installation of the damper housing 400, the damper assembly 500 and the guide structure, so the internal space of the front shell 110 is slightly larger, and when the damper housing 400, the damper assembly 500 and the guide structure need to be assembled into the front shell 110, the damper assembly 500 and the tower spring 700 are inserted from the opening of the front shell 110 along the attached Figure 16 The buckling direction of the middle and rear shells 120 enters the face shell 110. At this time, the large end of the tower spring 700 is pressed against the inner wall of the face shell 110. Considering the limit of the installation of the tower spring 700, a limit plate 710 is set on the inner wall of the face shell 110 near the tower spring 700, wherein the limit plate 710 is composed of a first limit plate 711, a second limit plate 712 and a third limit plate 713. The first limit plate 711 is integrally connected to the inner wall of the face shell 110, and the first limit plate 711 is located on the left side of the large end of the tower spring 700 (that is, attached). Figure 12 The second limit plate 712 is located on the right side of the large end of the tower spring 700 and is in contact with the large end of the tower spring 700 (that is, the attached Figure 12 The third limit plate 713 is located at the rear side of the large end of the tower spring 700 and is in contact with the large end of the tower spring 700 (that is, the other side of the fastening direction). Figure 12 Thus, by setting the limiting plate 710, the left, right and rear sides of the large end of the tower spring 700 are positioned.

[0085] For further information, see Figure 2 , 7As shown in the figure, a first sealing ring 540 is provided around the surface of the first door panel 510 facing the two opposite wall surfaces 410 of the damper housing 400. A first sealing groove 413 is provided on the opposite wall surfaces 410 of the damper housing 400. The first sealing ring 540 is adapted to be received in the first sealing groove 413, and the size of the first sealing ring 540 is larger than the size of the first opening 411.

[0086] A second sealing ring 550 is provided around the surface of the second door panel 520 facing the two opposite wall surfaces 410 of the damper housing 400. A second sealing groove 414 is provided on the opposite wall surfaces 410 of the damper housing 400. The second sealing ring 550 is adapted to be received in the second sealing groove 414, and the size of the second sealing ring 550 is larger than the size of the second opening 412.

[0087] Specifically in this embodiment, the first sealing ring 540 is provided around the surface of the first door panel 510 facing the two opposite wall surfaces 410 of the damper housing 400. Correspondingly, a first sealing groove 413 capable of accommodating the first sealing ring 540 is provided on the two opposite wall surfaces 410 of the damper housing 400, and the thickness of the first sealing ring 540 is greater than the depth of the first sealing groove 413. When the first door panel 510 is to block the first opening 411, at this time the first sealing ring 540 is squeezed between the first door panel 510 and the two opposite wall surfaces 410 of the damper housing 400. Since the size of the first sealing ring 540 is larger than the size of the first opening 411, the first sealing ring 540 can completely cover the first opening 411, thereby forming a seal.

[0088] With the same setting, the second sealing ring 550 is provided around the surface of the second door panel 520 facing the two opposite wall surfaces 410 of the damper housing 400. Correspondingly, a second sealing groove 414 capable of accommodating the second sealing ring 550 is provided on the two opposite wall surfaces 410 of the damper housing 400, and the thickness of the second sealing ring 550 is greater than the depth of the second sealing groove 414. When the second door panel 520 is to block the second opening 412, at this time the second sealing ring 550 is squeezed between the second door panel 520 and the two opposite wall surfaces 410 of the damper housing 400. Since the size of the second sealing ring 550 is larger than the size of the second opening 412, the second sealing ring 550 can completely cover the second opening 412, thereby forming a seal.

[0089] In addition, as a preferred method of this embodiment, the materials of the first sealing ring 540 and the second sealing ring 550 can both be selected as soft rubber materials (such as silica gel, TPE, TPR, TPU, PVC, etc.). The connection and fixing methods between the soft rubber materials and the damper door panels are both completed by secondary injection molding of soft rubber on the mold to ensure good adhesion between the soft rubber materials and the damper door panels (hard plastic parts) and the quality of the product.

[0090] Further, please refer toFigure 1 As shown, in some other embodiments of the present utility model, a third opening 422 is provided on the peripheral wall surface 420 of the air door housing 400, and the third opening 422 is adapted to install the fragrance bomb 300; a fourth opening 532 corresponding to the position of the third opening 422 is provided on the guiding structure, and the fourth opening 532 is used for the fragrance bomb 300 to be inserted into the guiding structure, and the fourth opening 532 is configured to have a preset length in the direction along the central axis so as to avoid the fragrance bomb 300 when the air door assembly 500 moves.

[0091] Thus, a fourth opening 532 corresponding to the third opening 422 is provided on the cylindrical object, and the fourth opening 532 has an avoidance space in the direction along the central axis so as to avoid the fragrance bomb 300 when the air door assembly 500 moves.

[0092] It can be understood that in this embodiment, the so-called cylindrical object is a cylindrical structure formed by surrounding once between the edges of the first door panel 510 and the second door panel 520 through the connecting member 530. At this time, in order to be able to install the fragrance bomb 300 into the air door housing 400 and avoid interference with the air door assembly 500, a fourth opening 532 is provided on the side of the cylindrical object facing the third opening 422 of the air door housing 400, so that the fragrance bomb 300 can be inserted between the air door assemblies 500 through the third opening 422 and the fourth opening 532.

[0093] Further, please refer to Figure 10 、 11 As shown, in an embodiment of the present utility model, the fragrance generator further includes a motor 800, and the motor 800 is used to drive the rotation of the rotating shaft 610. The rotation of the rotating shaft 610 will drive the cam 620 on the rotating shaft 610 to rotate synchronously. The cam 620 abuts against the first guiding post 511 on the first door panel 510 within a certain rotation angle range, and then presses the first guiding post 511 to move towards the inner side of the air door housing 400, thereby opening the first opening 411. When the cam 620 continues to rotate to another angle range and disengages from the first guiding post 511 on the first door panel 510, the air door housing 400 returns to its original position under the elastic action of the tower spring 700, so that the first door panel 510 closes the first opening 411, and the above movement is repeated.

[0094] Further, in another embodiment of the present utility model, the fragrance generator also includes a motor 800. At this time, the motor 800 is used to drive the gear to rotate, and then the gear can drive the rack to move, and the first opening 411 and the second opening 412 (at least one channel opening) are opened through the abutting cooperation between the protrusion and the air door panel. When the first opening 411 and the second opening 412 are opened, the fragrance of the fragrance bomb 300 can flow out of the air door housing 400 through the first opening 411 and the second opening 412 for the user to use.

[0095] Further, please refer to Figure 14 and 15 As shown in FIGS. 16 and 17, in an embodiment of the present utility model, the fragrance generator further includes a blower 900, which is installed on one side of the first opening 411 or the second opening 412 of the air door housing 400 for accelerating the fragrance emission speed.

[0096] Preferably, a blower 900 is provided at the front end of the air door housing 400 (i.e., the side of the first opening 411). The air inlet of the blower 900 is communicated with the air supply assembly 200 through a pipe joint. The blower 900 can be a fan. An aroma outlet is provided at the rear end of the air door housing 400 (i.e., the side of the second opening 412). The gas flow channel is arranged between the blower 900 and the aroma outlet. The blower 900 blows air into the gas flow channel, so that the air flow in the gas flow channel flows from front to back, enabling the fragrance of the fragrance cartridge 300 in the air door housing 400 to be mixed with the flowing air and blown out from the aroma outlet.

[0097] It can be understood that the blower 900 can also be a device such as a blower.

[0098] In another embodiment of the present utility model, the blower 900 can also be provided at the rear end of the air door housing 400 (i.e., the side of the second opening 412). At this time, the blower 900 can be a suction device. By pumping air on one side of the second opening 412, the air flow in the gas flow channel is accelerated, and the air carrying the fragrance of the fragrance cartridge 300 inside the air door assembly 500 is blown out from the aroma outlet.

[0099] When there are multiple fragrance channels, the multiple fragrance channels can be arranged in sequence in the vertical direction, so that the mouths of the multiple fragrance channels are all communicated with the blower 900, and only one blower 900 is needed.

[0100] Further, in an embodiment of the present utility model, a first guiding column 511 is vertically connected to the top of one of the first door panel 510 and the second door panel 520. A guiding groove adapted to the first guiding column 411 is provided on one of the first opening 411 and the second opening 412. The first guiding column 511 is adapted to reciprocate in the guiding groove.

[0101] In addition, the rib 531 extends in a direction away from the first guiding column 511 to be connected to the other of the first door panel 510 and the second door panel 520.

[0102] In another embodiment, the rib groove 421 extends in a direction away from the first guiding column 511 to be connected to the other of the first door panel 510 and the second door panel 520.

[0103] Preferably, when the air door driving structure 600 has a cam structure, the first guiding column 511 is adapted to directly abut against the cam 620; when the air door driving structure 600 has a rack and pinion structure, the first guiding column 511 is adapted to directly abut against the protruding portion at this time.

[0104] Please refer to Figure 1 As shown, in this embodiment, the first guiding column 511 is vertically connected to the top center position of the first door panel 510. A guiding groove structure is provided on the corresponding first opening 411, and the first guiding column 511 is inserted into the guiding groove structure, playing a role in supporting, limiting and guiding the reciprocating movement of the first door panel 510. Preferably, the rib 531 extends in a direction away from the first guiding column 511 and is vertically connected to the second door panel 520, so as to limit the guiding of the second door panel 520. Thus, through the mutual cooperation of the first guiding column 511 and the rib 531, the reliability and stability of the reciprocating movement of the air door assembly 500 are further improved.

[0105] Furthermore, please refer to Figure 5 As shown, in an embodiment of the present utility model, a protrusion is provided on one side of the rib 531 along a direction away from the first guiding column 511, so that a convex rib 5311 is formed at the contact combination of the rib 531 and the protrusion, and the volume of the convex rib 5311 is larger than that of the rib 531. A convex rib groove matching the convex rib is provided at the rib groove 421 corresponding to the convex rib. In this way, when assembling the air door assembly 500, the guiding can be provided first by the end of the rib 531 close to the first guiding column 511, then the convex rib 5311 is inserted, and the structural strength of the rib 531 is increased by using the convex rib 5311.

[0106] The length of the convex rib 5311 on the central axis is greater than the stroke of the air door assembly 500 moving relative to the air door housing 400 along the central axis during the operation of the fragrance generator; thus, when the air door assembly 500 moves, the convex rib 5311 can play a strong supporting role.

[0107] The difference between the length of the convex rib 5311 on the central axis and the stroke of the fragrance generator moving relative to the air door housing 400 along the central axis during operation does not exceed 3 mm. The advantage of such a setting is to avoid the convex rib 5311 being too long, so as to ensure that the length of the convex rib groove is not too large and ensure the structural strength of the structural member provided with the convex rib groove.

[0108] Specifically in this embodiment, the convex rib 5311 and the rib 531 have the same dimension in the width direction, the thickness of the convex rib 5311 is greater than that of the rib 531, and the length of the convex rib 5311 is slightly larger than the stroke of the air door assembly 500. In this way, when assembling the air door, the guiding can be provided first by the side of the rib 531 close to the first guiding column 511, and then the structural strength of the rib 531 is increased by using the convex rib, so that the reciprocating movement of the air door assembly 500 can rely on the convex rib to improve stability.

[0109] Preferably, the difference between the length of the rib 5311 on the central axis and the stroke of the fragrance generator moving relative to the air door housing 400 along the central axis during operation is 1 mm. In this way, it can be better ensured that the rib 5311 can provide strong support when the air door assembly 500 moves, and the structural strength of the structural member provided with the rib groove can also be better guaranteed, which is an optimization for the fragrance generator.

[0110] In addition, a guiding angle is provided at the insertion end of the rib 531 (i.e., the end for first inserting into the rib groove). The guiding angle of the rib 531 facilitates the smooth guiding and insertion of the end of the rib 531 into the rib groove 421.

[0111] A guiding angle is also provided on the same side of the rib 5311. The guiding angle of the rib 5311 facilitates the smooth guiding and insertion of the end of the protrusion into the rib groove.

[0112] In another embodiment of the present invention, a rib groove communicating with the rib groove 421 is formed on the side of the rib groove 421 facing away from the first guiding post 511, and the internal space of the rib groove is larger than the internal space of the rib groove 421 to facilitate the adaptation of the rib groove to the rib 5311.

[0113] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the protection scope of the present invention.
