It should be understood that such terms are interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0052] The following is combined with Figure 1-11 Introduce the technical solutions in the embodiments of this application.

[0053] See Figure 1-11 , an embodiment of the present application provides a fragrance switching device including a fragrance generating box body 10, a driving mechanism 20, at least two switching driving members 30 and at least two fragrance switching members 40; at least two fragrance box connecting positions 11 and at least two first vents 12 are provided on the fragrance generating box body 10, and the switching driving member 30, the fragrance switching member 40, the first vents 12 and the fragrance box connecting position 11 are arranged in a one-to-one correspondence; the first vents 12 are used to communicate with the fragrance box 50; the fragrance switching member 40 is slidably connected to the fragrance generating box body 10; a first transmission structure 31 and a second transmission structure 32 are provided on the switching driving member 30, the first transmission structure 31 is transmission-connected to the driving mechanism 20, and the second transmission structure 32 is transmission-connected to the fragrance switching member 40; the driving mechanism 20 is used to drive the first transmission structure 31 and the second transmission structure 32 to drive the fragrance switching member 40 to move to a first position capable of covering the first vents 12 or to a second position capable of exposing the first vents 12.

[0054] Specifically, the number of the switching driving members 30 , the fragrance switching members 40 , the first vents 12 and the fragrance box connecting positions 11 are the same.

[0055] It should be noted that the number of switching drive components 30, fragrance switching components 40, first ventilation ports 12 and fragrance box connection positions 11 depends on actual conditions. This application does not limit the number of switching drive components 30, fragrance switching components 40, first ventilation ports 12 and fragrance box connection positions 11.

[0056] In some specific embodiments, see Figure 1-5 The number of the switching drive member 30, the fragrance switching member 40, the first vent 12 and the fragrance box connecting position 11 can all be two.

[0057] In other specific embodiments, see Figure 8 The number of the switching drive member 30, the fragrance switching member 40, the first vent 12 and the fragrance box connecting position 11 can all be four.

[0058] In some embodiments, the fragrance switching device includes a plurality of fragrance boxes 50 , which are connected to the fragrance generating box body 10 via a fragrance box connecting portion 11 ; specifically, the first vent 12 is used to communicate with the interior of the fragrance box 50 .

[0059] In some embodiments, driven by the driving mechanism 20, the first transmission structure 31 can drive the second transmission structure 32 to move, so that the second transmission structure 32 drives the fragrance switching component 40 to slide relative to the fragrance generating box body 10, thereby causing the fragrance switching component 40 to slide to the first position, or slide to the second position.

[0060] Among them, the first position is the position where the fragrance switching component 40 blocks the first ventilation port 12. At this time, the fragrance box 50 corresponding to the fragrance switching component 40 cannot emit fragrance due to the closure that prevents airflow from flowing; the second position is the position where the fragrance switching component 40 exposes the first ventilation port 12. At this time, the fragrance box 50 corresponding to the fragrance switching component 40 can emit fragrance due to the airflow that can flow.

[0061] Specifically, the driving mechanism 20 can indirectly drive at least one of the two fragrance switching components 40 to move to the second position, and at the same time can indirectly drive the other fragrance switching components 40 to move to the first position. In this way, it can ensure that the fragrance switching device switches to release the target fragrance, and can also prevent the leakage of other fragrances, thereby solving the problem of mixed fragrances and ensuring the uniqueness of the switched fragrance.

[0062] Exemplarily, the number of the switching drive component 30, the fragrance switching component 40, the first vent 12 and the fragrance box connection position 11 is four, and the driving mechanism 20 can indirectly drive one of the fragrance switching components 40 to move to the second position, and at the same time can indirectly drive the other three fragrance switching components 40 to move to the first position.

[0063] Furthermore, the driving mechanism 20 can drive the fragrance switching component 40 to reciprocate between the first position and the second position. That is, the driving mechanism 20 can drive the fragrance switching component 40 to move from the first position to the second position, and can also drive the fragrance switching component 40 to move from the second position to the first position without the aid of components such as a return spring. In this way, the structure of the fragrance switching device can be simplified, the convenience of assembly can be improved, and the transmission efficiency between the driving mechanism 20 and the fragrance switching component 40 can be improved.

[0064] 19. The fragrance switching device of the present application includes a fragrance generating box body, a driving mechanism, at least two switching driving members and at least two fragrance switching members; at least two fragrance box connecting positions are provided on the fragrance generating box body, and the switching driving member, the fragrance switching member and the fragrance box connecting positions are arranged in a one-to-one correspondence; a first ventilation opening connected to the fragrance box is provided on the fragrance generating box body; the fragrance switching member is slidably connected to the fragrance generating box body; a first transmission structure and a second transmission structure are provided on the switching driving member, the first transmission structure is transmission-connected to the driving mechanism, and the second transmission structure is transmission-connected to the fragrance switching member; the driving mechanism is used to drive the first transmission structure and the second transmission structure to drive the fragrance switching member to move to a first position capable of covering the first ventilation opening or to a second position capable of exposing the first ventilation opening; in this way, the driving of the fragrance switching member can be efficiently realized, and then the covering or exposure of the first ventilation opening by the fragrance switching member can be efficiently realized, and then the fragrance switching can be efficiently realized. At the same time, the fragrance switching device of the present application has a simple structure and is easy to assemble.

[0065] In the embodiment of the present application, one of the second transmission structure 32 and the fragrance switching component 40 is provided with a sliding protrusion 41, and the other is provided with a sliding groove 321 adapted to the sliding protrusion 41; the sliding protrusion 41 can slide in the sliding groove 321 to enable the fragrance switching component 40 to move between the first position and the second position.

[0066] In some embodiments, a sliding protrusion 41 is provided on the fragrance switching member 40, and a slide groove 321 is provided on the second transmission structure 32; driven by the driving mechanism 20, the sliding protrusion 41 can move relative to the slide groove 321 to move the fragrance switching member 40 to the first position or to the second position.

[0067] Specifically, the slide groove 321 is an eccentric slide groove with a closed curve. In this way, it can not only enable the fragrance switching component 40 to move between the first position and the second position, but also prevent the sliding protrusion 41 from escaping from the slide groove 321 during the movement relative to the slide groove 321.

[0068] In the embodiment of the present application, the driving mechanism 20 includes a motor 21 and an intermediate driving member 22 ; the motor 21 and the intermediate driving member 22 are transmission-connected, and the intermediate driving member 22 and the first transmission structure 31 are transmission-connected.

[0069] Specifically, the motor 21 can drive the first transmission structure 31 to move through the intermediate driving member 22 .

[0070] In some embodiments, the intermediate driving member 22 may be a spur gear, and accordingly, the first transmission structure 31 may be a spur gear transmission structure that matches the spur gear. In this way, the intermediate driving member 22 and the first transmission structure 31 are transmitted through gear meshing.

[0071] Furthermore, the switching drive member 30 can be a split drive member, that is, the first transmission structure 31 and the second transmission structure 32 are separately arranged. Specifically, the split first transmission structure 31 and the second transmission structure 32 can be fixedly connected by screw connection or adhesive connection.

[0072] Preferably, the switching drive member 30 is an integrated drive member, that is, the first transmission structure 31 and the second transmission structure 32 are integrally arranged. This can reduce the assembly complexity of the fragrance switching device and improve the assembly convenience of the fragrance switching device.

[0073] In the embodiment of the present application, the fragrance generating box body 10 includes a fragrance generating upper shell 13, a fragrance generating middle shell 14 and a fragrance generating lower shell 15; the fragrance generating upper shell 13 and the fragrance generating middle shell 14 are detachably connected, and the fragrance generating middle shell 14 and the fragrance generating lower shell 15 are detachably connected.

[0074] Specifically, the fragrance generating upper shell 13 and the fragrance generating middle shell are screwed together, and the fragrance generating middle shell 14 and the fragrance generating lower shell 15 are screwed together.

[0075] Furthermore, the first vent 12 is provided on the fragrance generating middle shell 14 ; the fragrance switching member 40 is slidably connected to the fragrance generating middle shell 14 .

[0076] In the embodiment of the present application, the fragrance switching device further includes a connecting assembly 60 , which is fixedly connected to the fragrance generating box 10 ; the driving mechanism 20 is fixedly connected to the connecting assembly 60 , and the switching driving member 30 is rotationally connected to the connecting assembly 60 .

[0077] In some embodiments, the connection assembly 60 includes a first connection member 61 and a second connection member 62 , and the first connection member 61 and the second connection member 62 are detachably connected.

[0078] Specifically, the first connecting member 61 and the second connecting member 62 are screwed together.

[0079] In some embodiments, the motor 21 is detachably connected to the second connecting member 62 , and the switching drive member 30 is rotatably connected to the second connecting member 62 .

[0080] Specifically, the switching drive member 30 can be rotatably connected to the second connecting member 62 by locking the screw 210 , thereby achieving the rotatable connection between the switching drive member 30 and the second connecting member 62 .

[0081] In some embodiments, the first connecting member 61 and the fragrance generating shell 14 are enclosed to form a switching member sliding position, and the fragrance switching member 40 can slide in the switching member sliding position under the drive of the motor 21; the switching member sliding position has a first end and a second end relatively set, when the fragrance switching member 40 slides to the first end close to the switching member sliding position, the fragrance switching member 40 is in the first position; when the fragrance switching member 40 slides to the second end close to the switching member sliding position, the fragrance switching member 40 is in the second position.

[0082] In an embodiment of the present application, the fragrance switching device also includes a fan 70, which is detachably connected to the connecting component 60; the fragrance generating box 10, the fragrance switching component 40, the connecting component 60 and the fan 70 cooperate to form an air inlet duct 150 and an air outlet duct 160, and the air inlet duct 150 and the air outlet duct 160 can both be connected to the first ventilation port 12 through the fragrance switching component 40.

[0083] Specifically, the fan 70 is screwed to the second connecting member 62 .

[0084] In some embodiments, the fragrance generating shell 14, the first connecting member 61, the second connecting member 62 and the fragrance switching member 40 cooperate to form an air inlet duct 150; the first connecting member 61, the second connecting member 62, the fragrance switching member 40 and the fan 70 cooperate to form an air outlet duct 160; the air inlet duct 150 and the air outlet duct 160 are relatively independent, so that the fragrance output efficiency of the fragrance switching device can be improved.

[0085] In some embodiments, an air inlet 151 is provided on the fragrance generating lower shell 15 , and the air inlet duct 150 is connected to the outside through the air inlet 151 .

[0086] In an embodiment of the present application, a second vent 42 adapted to the first vent 12 is provided on the fragrance switching component 40; when the fragrance switching component 40 moves to the second position, the air inlet duct 150 and the air outlet duct 160 can both be connected to the first vent 12 through the second vent 42.

[0087] Specifically, the first vent 12 is provided on the fragrance generating middle shell 14 .

[0088] In some embodiments, the fragrance switching device includes two fragrance switching members 40. For ease of description, the two fragrance switching members 40 are described as a first fragrance switching member 40 and a second fragrance switching member 40. When the first fragrance switching member 40 moves to the second position, the second vent 42 on the first fragrance switching member 40 can be aligned with the first vent 12 corresponding to the first fragrance switching member 40, so that the air inlet 150 and the air outlet 160 can both communicate with the second vent 42 on the first fragrance switching member 40 and the first vent 12 corresponding to the first fragrance switching member 40. At this time, the fragrance box 50 corresponding to the first fragrance switching member 40 can emit fragrance.

[0089] When the first fragrance switching component 40 moves to the second position, the second fragrance switching component 40 moves to the first position. At this time, the second vent 42 on the second fragrance switching component 40 cannot be aligned with the first vent 12 corresponding to the second fragrance switching component 40, and thus the air inlet 150 cannot be connected to the first vent 12 corresponding to the second fragrance switching component 40 through the second vent 42 on the second fragrance switching component 40, and the air outlet 160 cannot be connected to the first vent 12 corresponding to the second fragrance switching component 40 through the second vent 42 on the second fragrance switching component 40. At this time, the fragrance box 50 corresponding to the second fragrance switching component 40 cannot emit fragrance.

[0090] Specifically, when the fragrance switching device is turned off, the first fragrance switching component 40 and the second fragrance switching component 40 can both move to the first position, so that the first fragrance switching component 40 and the second fragrance switching component 40 cannot emit fragrance, thereby avoiding waste of fragrance.

[0091] In the embodiment of the present application, the second ventilation port 42 includes a plurality of second ventilation portions 421 , at least one of the plurality of second ventilation portions 421 can communicate with the air inlet duct 150 , and at least another of the plurality of second ventilation portions 421 can communicate with the air outlet duct 160 .

[0092] Specifically, the first ventilation opening 12 includes a plurality of first ventilation portions 121 , and the first ventilation portions 121 correspond to and match the second ventilation portions 421 .

[0093] For example, the first ventilation opening 12 may include six first ventilation portions 121 , and the second ventilation opening 42 may include five second ventilation portions 421 .

[0094] In the embodiment of the present application, the fragrance switching device further includes a fragrance adapter 80 , which is connected to the air outlet duct 160 ; the fragrance adapter 80 is detachably connected to the fragrance generating box body 10 .

[0095] In this way, the assembly angle of the fragrance adapter 80 relative to the fragrance generating box 10 can be adjusted, thereby enabling the fragrance switching device to emit fragrance at multiple angles, allowing the fragrance switching device to be flexibly adapted to more application scenarios.

[0096] In some embodiments, the fragrance adapter 80 is detachably connected to the fragrance generating lower shell 15; specifically, an adapter connection position is provided on the fragrance generating lower shell 15, and the fragrance adapter 80 is detachably connected to the fragrance generating lower shell 15 through the adapter connection position.

[0097] Preferably, the fragrance adapter 80 is plugged into the fragrance generating lower shell 15 via the adapter connection position.

[0098] In the embodiment of the present application, the fragrance switching device further includes at least one rotating member 140 ; ​​the rotating member 140 is disposed between the switching drive member 30 and the fragrance switching member 40 , and the rotating member 140 is rotationally connected to the fragrance switching member 40 .

[0099] In some embodiments, the rotating member 140 is arranged between the sliding protrusion 41 and the slide groove 321; the rotating member 140 can be a bearing, and the inner ring of the bearing is fixedly connected to the sliding protrusion 41. In this way, the movement friction between the sliding protrusion 41 and the slide groove 321 can be reduced, thereby improving the service life of the fragrance switching device.

[0100] In the embodiment of the present application, the fragrance box 50 is detachably connected to the fragrance generating box body 10. In this way, the fragrance box 50 can be easily replaced, thereby reducing the cost of using the fragrance switching device.

[0101] In the embodiment of the present application, the fragrance switching device further includes at least one elastic fixing member 130 ; the elastic fixing member 130 is movably connected to the fragrance generating box body 10 ; the fragrance box 50 can be detachably connected to the fragrance generating box body 10 via the elastic fixing member 130 .

[0102] In some embodiments, the elastic fixing member 130 has a deformation portion 131 and a fragrance box connecting portion 132, and the fragrance box connecting portion 132 has a limiting portion 1321; the fragrance generating upper shell 13 and the fragrance generating middle shell 14 cooperate to form the elastic fixing member connection position; the deformation portion 131 and the limiting portion 1321 are accommodated in the elastic fixing member connection position.

[0103] Correspondingly, the fragrance box 50 is provided with a first recessed structure 51 adapted to the fragrance box connecting portion 132 .

[0104] Specifically, the deformation portion 131 can be deformed by compression under force, so that the fragrance box connecting portion 132 moves relative to the elastic fixing member connection position, thereby enabling the fragrance box 50 to be conveniently assembled or disassembled with the fragrance generating box body 10.

[0105] Specifically, after the fragrance box 50 and the fragrance generating box body 10 are assembled, the deformation portion 131 can be reset and deformed to a certain extent to push the limiting portion 1321 to abut against the elastic fixing member connection position, thereby making the fragrance box connection portion 132 protrude as much as possible from the elastic fixing member connection position, and then making the fragrance box connection portion 132 cooperate with the first recessed structure 51, so that the elastic fixing member 130 clamps the fragrance box 50, thereby achieving the fixation of the fragrance box 50.

[0106] Specifically, the limiting portion 1321 can limit the movement stroke of the elastic fixing member 130, thereby preventing the elastic fixing member 130 from escaping from the elastic fixing member connection position.
