It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0045] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0046] The present embodiment provides a rearview mirror aroma diffuser, which is installed in the rearview mirror. It can not only switch and mix the fragrance types by itself, but also adjust the concentration of the fragrance according to the user's preference.

[0047] like Figure 1 As shown, the aromatherapy machine includes an aromatherapy cream door 1, an aromatherapy cream holder 2, a back cover 3, an air duct back cover 4, an aromatherapy body 5, a gear 6, a stepper motor 7, a motor holder 8, EVA foam 9, a reflector 10, a front cover 11, a fan holder 12, an air duct front cover 13, a blower 14 and a silicone sleeve 15.

[0048] The ointment door 1, the ointment bracket 2, the gear 6, and the stepping motor 7 constitute the ointment door assembly. Figures 1 to 3As shown, the ointment door assembly is arranged on the motor bracket 8, and the motor bracket 8 is mounted on the bottom plate of the rear cover 3, which is provided with at least two groups of aromatherapy mounting holes and motor mounting holes, the ointment bracket 2 is placed on the aromatherapy mounting holes and fixed to the motor bracket 8 by screws, the stepper motor 7 is placed in the motor mounting holes and fixed to the motor bracket 8 by screws, the ointment door 1 is sleeved on the ointment bracket 2, and its bottom is provided with rotating teeth, and the output end of the rotating shaft of the stepper motor 7 is meshed and connected with the rotating teeth of the ointment door 1 through the gear 6, so as to form a rotating device. The ointment door 1 is symmetrically provided with first vents 16 on the opposite sides, and the ointment bracket 2 is symmetrically provided with second vents 17 on both sides, and the overlapping area of ​​the first vent 16 and the second vent 17 is the air hole for the air inlet and outlet of the fragrance body 5, and the ointment door 1 can rotate relative to the ointment bracket 2 under the drive of the rotating device, and the size of the air hole can be adjusted to make the air hole in an open or closed state, or adjust the opening angle (i.e., the rotation angle of the ointment door 1 relative to the ointment bracket 2).

[0049] The EVA foam 9 is pasted between the motor bracket 8 and the bottom plate of the rear cover 3, which is helpful to alleviate the vibration frequency and noise of the stepper motor 7 when working. The lower part of the multiple fragrance bodies 5 with different fragrances is placed in the motor bracket 8, and the upper part is placed in the cream bracket 2, and the cream door assembly forms an independent opening and closing door structure of the fragrance body 5.

[0050] On the front and rear sides of the perfume door assembly, the stoppers of the air duct front cover 13 and the air duct rear cover 4 are aligned and snapped together. The air duct front cover 13 and the air duct rear cover 4 are respectively fixed to the motor bracket 8 with screws, and the perfume door assembly is wrapped between the air duct front cover 13 and the air duct rear cover 4. Thus, the perfume door 1, the perfume bracket 2, the air duct rear cover 4, the air duct front cover 13 and other air duct components form the air duct of the aromatherapy machine. In this embodiment, the wind direction in the air duct is as follows Figure 4 and Figure 5 In addition, two vertical ribs 18 are symmetrically arranged between the two first ventilation holes 16 on the outer side of the perfume door 1. When the first ventilation hole 16 is located in the middle of the air duct, the outer side of the vertical ribs 18 contacts the inner side of the air duct rear cover 4 and the air duct front cover 13, which is used to separate the air duct and promote the air flow to the inside of the fragrance body 5.

[0051] The silicone sleeve 15 is installed at one end of the air duct, and the air outlet of the blower 14 is inserted through the opening on the silicone sleeve 15, blowing air into the air duct, which helps to accelerate the release of the fragrance of the fragrance body 5. Specifically, the silicone sleeve 15 can be inserted into the square hole above the air duct through the square step. The center of the silicone sleeve 15 has a square hole. The air outlet of the blower 14 is square, and the air outlet of the blower 14 is inserted through the square hole. The connection of the square structure can greatly ensure the stability of the plug-in connection. Figure 6 As shown, after the blower 14 is tilted to the left at a certain angle, the air outlet is inserted into the square hole of the silicone sleeve 15 so as to blow air into the aromatherapy machine.

[0052] The front cover 11 is aligned with the four side edges of the rear cover 3. The front cover 11 is buckled on the rear cover 3. The rear cover 3 and the front cover 11 form the shell of the aromatherapy machine. The perfume door assembly in the shell is installed on the bottom plate of the rear cover 3 through the motor bracket 8. Among them, the front cover 11 is provided with a lens groove on the front side, and double-sided adhesive is pasted in the lens groove. The back of the reflector 10 faces the lens groove, and the reflector 10 is embedded in the lens groove by double-sided adhesive. The bottom plate of the rear cover 3 is provided with a fragrance outlet 19 and an air inlet 20 on both sides (see Figure 7 ), used for dispersing fragrance and taking in air. In this embodiment, a plurality of screw columns are provided on the inner side of the rear cover 3, and screw holes are provided on the rear side of the air duct rear cover 4. The air duct rear cover 4 is fixedly connected to the rear cover 3 by screws passing through the screw holes and then screwing into the screw columns.

[0053] Above the air inlet 20, a screw column is provided on the bottom plate of the rear cover 3, and the fan bracket 12 is installed on the bottom plate by screwing the screw into the bolt column, and the blower 14 is installed at one end of the housing through the fan bracket 12. When the air hole is in the open state, the air blown by the blower 14 passes through the second vents 17 on both sides of the perfume holder 2 and blows into the fragrance body 5, and the airflow mixed with the fragrance enters the air duct and is blown out from the fragrance outlet 19.

[0054] like Figure 6 and Figure 8 As shown, the process of dispersing fragrance is now described by taking three fragrance bodies 5 (respectively fragrance bodies A, B, and C) as an example, and the direction of the arrow is the flow direction of the air blown by the blower 14. Taking fragrance body C as an example, the process of dispersing fragrance is described as follows:

[0055] 1. The blower 14 draws air in from the air inlet 20 and blows the air into the air duct through the air outlet of the blower 14;

[0056] 2. The air holes of the fragrance bodies A and B are closed (i.e., the first ventilation opening 16 and the second ventilation opening 17 have no overlapping area), and the vertical ribs 18 on the side of the perfume door 1 of the fragrance bodies A and B are rotated to the middle of the air duct (i.e., between the two fragrance bodies 5), and the wind blown into the air duct passes through the gap between the side of the fragrance bodies A and B and the air duct assembly;

[0057] 3. Open the air hole of the fragrance body C (i.e., the first ventilation hole 16 and the second ventilation hole 17 have an overlapping area), and the vertical ribs 18 on the side of the perfume door 1 of the fragrance body C block the gap between the side of the perfume door 1 and the air duct component (when the air hole is fully opened, the vertical ribs 18 completely block the gap, and when the air hole is partially opened, they block part of the gap), and the wind can only blow into the fragrance body C from one side of the fragrance body C, and blow out from the air hole on the other side of the fragrance body C with fragrance;

[0058] 4. The wind carrying the fragrance of the fragrance body C flows from the left air duct to the fragrance outlet 19, and is discharged from the fragrance outlet 19 to achieve fragrance dispersion.

[0059] When the two fragrances A and B are mixed to diffuse fragrance, the blower 14 is used to suck air from the air inlet and blow the wind into the air duct, the air holes of the fragrance bodies A and B are opened, and the air holes of the fragrance body C are closed. The wind entering the air duct is blown through the inside of the fragrance bodies A and B in turn, and then flows around the fragrance body C. The two fragrances A and B are mixed during the flow, and the mixed fragrance is discharged from the fragrance outlet 19, thereby realizing the DIY of fragrance diffusion and aroma.

[0060] Or in another embodiment, the outer side of the ointment door 1 is not provided with vertical ribs 18, and above the rotating teeth, between the two first vents 16, such as Fig. 9 As shown, the side of the balm door 1 is symmetrically provided with an arc surface structure, the top of which contacts the inner side of the air duct rear cover 4 and the air duct front cover 13, and is used to separate the air duct. When the balm door 1 rotates, as the rotation angle of the balm door 1 changes, the distance between the top end of the arc surface structure (the arc surface tangent point closest to the air duct assembly) and the air duct assembly changes accordingly, thereby adjusting the gap between the side of the balm door 1 and the air duct assembly.

[0061] The curvature radius ρ of the curved surface structure on the ointment door 1 can be calculated according to the following formula:

[0062]

[0063] Where ρ0 is the radius of the minor axis, C is the air duct adjustment constant, and Φ is the distance between any point on the surface and the midpoint of the rotating axis relative to the minor axis of the arc mechanism ( Fig. 9 The value range of Φ is [0, π / 2]. Preferably, the value range of Φ is [π / 6, π / 2]. Here, only the size of the angle is considered, and the direction of the angle is not considered. When converted to the polar coordinate system, it is:

[0064]

[0065] in, is the polar coordinate of any point on the surface, the origin of the polar coordinate is the rotation axis, The initial position of the angle is any minor axis, It represents the remainder of the polar coordinate angle value with respect to π / 2.

[0066] The use of such a curved surface structure can solve the problem in the rotary adjustment method that when the arc structure rotates to different angles, the air duct becomes narrower (or wider) by different degrees corresponding to the unit rotation angle. During the rotation of the balm door 1, the rotation angle and the air duct formed by the side wall of the air duct assembly can be more evenly progressive, so that the balm door 1 and the channels on both sides can be changed synchronously.

[0067] The fragrance body 5 used in this embodiment is as follows Figures 10 to 13As shown, it includes an ointment upper cover 21, a hook 22, an ointment middle barrel 23 and an ointment lower cover 24. The ointment upper cover 21 and the ointment lower cover 24 are respectively installed at the upper and lower ends of the ointment middle barrel 23. The ointment is loaded in the ointment middle barrel 23. The side wall of the ointment middle barrel 23 is hollow to facilitate the diffusion of fragrance.

[0068] A base plate is provided at the bottom of the ointment upper cover 21, and an ointment identification contact PCBA board 25 is arranged on the base plate. The ointment identification contact PCBA board 25 includes a storage module and a balance module. The storage module stores the fragrance information of the ointment loaded in the ointment barrel 23, and the balance module is used to measure the ointment remaining in the ointment barrel 23.

[0069] The hook 22 is clamped at the center of the bottom plate. A mushroom head is provided at the center of the hook 22 . The mushroom head extends upward from the bottom plate through the center hole of the bottom plate to be clamped with the self-locking switch buckle 26 .

[0070] The aromatherapy machine of this embodiment further includes a control device, which includes a TYPE-C-PCBA board 27 , a button 28 and a main PCBA board 29 .
