[0041] In order to more fully understand the technical content of the present invention, the present invention will be further introduced and explained in conjunction with the accompanying drawings and specific embodiments below; it should be noted that if there are descriptions such as "first" and "second" in the text, they are used to distinguish different components, etc., and do not represent the order of precedence, nor do they limit the "first" and "second" to different types.

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present invention.

[0043] Example

[0044] like Figures 1 to 19 As shown, a car-mounted aromatherapy device shown in this embodiment includes a base 1 and a shell 2. The base 1 is provided with a fragrance diffusion component 3 for diffusing fragrance, and the base 1 is provided with an air inlet 10 connected to the internal space of the fragrance diffusion component 3, that is, the air inlet is used to allow air to enter the fragrance diffusion component and bring out the fragrance, thereby achieving the purpose of diffusing fragrance; the shell 2 is rotatably sleeved on the outside of the base 1 and is used to close or open the air inlet 10, that is, when the shell rotates relative to the base, the air inlet can be opened or closed, and a cavity 11 for accommodating the fragrance diffusion component 3 is formed between the shell 2 and the base 1, and a plurality of decorative shells are further provided between the shell 2 and the fragrance diffusion component 3, which are arranged in sequence from the inside to the outside and surround the fragrance diffusion component 3. The upper end of the shell is open to reveal the internal fragrance diffusion component. And the decorative shell, adjacent decorative shells are rotatably connected, that is, while all the decorative shells rotate in the same direction, adjacent decorative shells can also rotate relative to each other, and the outermost decorative shell is rotatably connected to the shell body 2, that is, the decorative shell can be driven to rotate synchronously while the shell body rotates, and after the shell body 2 and the base 1 rotate relative to each other, the air inlet 10 is opened and one end of the decorative shell is tilted and protrudes from the shell body 2, and the tilted ends of all decorative shells are staggered; it can be understood that in order to facilitate the mutual rotation and tilting of the decorative shells, the outer shapes of the fragrance diffuser component and the decorative shell are designed to be spherical transition surfaces, which have the characteristics of low friction and good air tightness. In this embodiment, the spherical transition surfaces of adjacent components can contact each other or have a small gap.

[0045] In the above, the rotating shell is matched with the multiple decorative shells inside, and one end of the decorative shell inside is tilted upward during the rotation, and the tilted ends of the multiple decorative shells are staggered, so that the tilted ends of the multiple decorative shells can be used to form a flower-shaped decoration (such as Figure 16 The decorative shell can be retracted into the shell after the shell is rotated in the reverse direction. The air inlet is opened by the rotation, so that the outside air can enter the fragrance diffusion component and bring out the fragrance. The fragrance can be diffused outward through the gaps between the decorative shells after the rotation and between the decorative shells and the fragrance diffusion component, and can also overflow outward through the opened air inlet. After the air inlet is closed by reverse rotation, the inlet flow in and out of the air is reduced. Whether to open the rotating air inlet can be determined according to actual needs to avoid unnecessary volatilization waste of the car-mounted aromatherapy, thereby improving practicality.

[0046] As a preference, Figure 1 and Figure 4As shown, in this embodiment, the number of decorative shells is preferably three, which are specifically the first decorative shell 4, the second decorative shell 5 and the third decorative shell 6 from the inside to the outside, that is, the third decorative shell is rotatably connected to the shell; it can be understood that in order to achieve the rotational connection, two rotation shafts 51 are symmetrically protruded on the outer circumference of the first decorative shell 4, the second decorative shell 5 and the third decorative shell 6, and the second decorative shell 5 is also provided with a through hole 52 for accommodating the rotation shaft of the first decorative shell 4. The third decorative shell 6 is also provided with a through hole 52 for accommodating the rotation shaft of the second decorative shell 4, and the rotation shaft on the third decorative shell 6 is rotatably set on the inner wall of the shell. In order to achieve the staggered setting of the raised ends of the three, the connecting lines of the two rotation shafts 51 on the first decorative shell 4, the second decorative shell 5 and the third decorative shell 6 are cross-staggered in sequence.

[0047] Preferably, a relief opening 21 cooperating with the air inlet 10 is provided on the shell 2. After the shell 2 and the base 1 rotate relative to each other, the relief opening 21 and the air inlet 10 are connected or closed in a staggered manner in the front and back directions, that is, the overlap between the relief opening and the air inlet on the shell is utilized to make the air inside and outside flow.

[0048] Preferably, the base 1 is rotatably disposed in the shell 2, and a fixing seat 7 protruding backward from the shell is provided in the middle of the bottom of the base 1. The fixing seat can be made into an integral part with the base, or can be combined and connected in a detachable manner. The air inlet 10 is provided between the fixing seat 7 and the base 1, and the avoidance port 21 is provided between the shell 2 and the fixing seat 7, that is, the air inlet and the avoidance port are both provided around the fixing seat; of course, the air inlet and the avoidance port can be one, or two or more, and in this embodiment, there are two symmetrically arranged ones.

[0049] The first and second latches 71 are symmetrically provided on the inner wall of the opening; the first latch 71 is convexly provided on the outer periphery of the fixing seat 7 and is engaged with the first latch 71; the fixing seat 7 is also provided with an elastic arm 72 which is engaged with the second latch 13, and one end of the elastic arm 72 extends outward from the shell 2 to release the lock between it and the first latch; during assembly, the first latch is first inserted into the first latch, and then the elastic arm is engaged with the second latch, because the elastic arm is elastic, it can be easily inserted into the second latch to complete the assembly; in this structure, the locking connection is achieved by the elastic arm, and one end of the elastic arm extends outward from the shell. Compared with the existing rigid latch connection structure, the elastic deformation ability of the elastic arm is utilized, so that the exposed part of the elastic arm can be pressed to cause it to be elastically deformed to release the lock between it and the second latch, thereby facilitating assembly and disassembly between the two.

[0050] Preferably, the elastic arm 72 includes a straight section 73 protruding from the front end of the fixing seat 7 and a pressing section 74 extending from the inside to the outside of the shell 2. The straight section and the pressing section are made of one piece, and the inner ends of the two are connected to form a U-shaped structure. The pressing section 74 is protruded with a second buckle 75 that engages with the second slot 13, and a deformation space 76 is provided between the pressing section 74 and the straight section 73 for the pressing section 74 to be pressed and deformed toward the straight section 73, thereby realizing the pressing, deformation and unlocking operation of the elastic arm.

[0051] In a specific implementation case, a number of through holes 77 connected to the fragrance diffusion component can be further provided on the fixing base 7, so that the fragrance diffusion component is always connected and ventilated with the external air, thereby achieving the purpose of continuous fragrance diffusion, and the air intake hole that is rotated to open is only used to increase the amount of air intake to improve the fragrance diffusion effect; of course, the through hole is not necessary. In the solution where the through hole is not provided, the flow of internal and external air can be conveniently reduced by closing the air intake hole, thereby reducing unnecessary waste of fragrance diffusion materials.

[0052] In a specific implementation case, a clip 8 can be detachably provided on the outer end of the fixing seat 7, so that the car aroma diffuser can be clamped on the air outlet by the clamping effect of the clip, and the air flow speed inside and outside the car can be increased in conjunction with the air conditioning in the car to improve the fragrance diffusion effect; of course, it is also possible to not use a clip and directly use the supporting function of the fixing seat to place it in the car for natural fragrance diffusion.

[0053] Preferably, the fragrance diffusion component 3 includes an inner shell 31 that is snap-fitted into the middle of the base 1 and a fragrance diffusion piece 32 provided in the inner shell 31. The fragrance diffusion piece is a solid ointment or a fragrance diffusion cotton piece that absorbs fragrance liquid. The air inlet 10 and the through hole 77 are both connected to the internal space of the inner shell 31, so that the air can contact the internal fragrance diffusion piece and bring out the fragrance. The three decorative shells are arranged around the inner shell 31 in sequence, and after one end of the decorative shell is tilted up, a gap is formed between the decorative shell and the inner shell 31 that is connected to the internal space of the inner shell 31.

[0054] Preferably, the shell 2 includes a bottom shell 22 rotatably mounted on the outside of the base 1 and an upper shell 23 threadedly connected to the bottom shell 22 and arranged around the decorative shell. The upper end of the upper shell is designed to be open, and the two rotating shafts on the third decorative shell 6 are rotatably arranged between the bottom shell 22 and the upper shell 23, that is, a U-shaped groove 24 for accommodating the rotating shaft is provided on the bottom shell 22. After the upper shell is assembled, the opening of the U-shaped groove is covered to confine the rotating shaft in the U-shaped groove; in this way, after opening the upper shell, the entire decorative shell can be easily removed outward, and then the inner shell 31 can be removed to facilitate the replacement of the fragrance sheet in the inner shell.

[0055] In a specific embodiment, the front end surface of the inner shell 31 is penetrated by a plurality of air outlet holes 33 connected to the outside, so that the air entering the inner shell can also flow out through the air outlet holes, that is, the fragrance diffusion component and the external air are always kept in a normally open contact state; of course, the air outlet holes are not necessary, and the fragrance can be diffused only through the gap between the decorative shells after rotating and tilting, and the size of the gap can be reduced or even closed after retracting to its original state.

[0056] Preferably, a raised limiting portion 25 is provided on the inner surface of the bottom shell 22, and an arcuate groove 14 is recessed on the bottom of the base 1 for accommodating the limiting portion 25 and guiding the limiting portion 25 to rotate circumferentially, that is, the arcuate groove is extended along the circumferential direction. Through the cooperation of the arcuate groove and the limiting portion, the maximum rotation angle of the shell and the decorative shell can be limited to avoid damage to the car aroma diffuser due to excessive rotation.

[0057] Preferably, a protruding portion 15 is provided on the surface of the base 1 at a position corresponding to each decorative shell, which causes one end of the decorative shell to tilt up during the rotation process. A groove 53 is provided at the bottom of the decorative shell to accommodate the protruding portion 15. The side of the groove 53 facing away from the rotation direction is an inclined surface extending circumferentially and gradually approaching the base. That is, when the decorative shell needs to be rotated to open and tilted, the inclined surface and the protruding portion 15 are in rotational contact during the rotation of the decorative shell. Because the farther the inclined surface is from the protruding portion, the closer it is to the base, the decorative shell will be gradually lifted up by the protruding portion during the continuous rotation process. Of course, in order to facilitate the cooperation between the protruding portion and the inclined surface on one side of the groove, the upper end of the protruding portion will also be provided with a matching inclined surface. It can also be understood that in order to achieve the purpose of tilting one end, the other end of the decorative shell will inevitably sink downward. As the sinking end, the bottom of the decorative shell is also recessed with a clearance notch 54 for one end to sink toward the base 1, that is, there is a space between the decorative shell and the base at the clearance notch, and the clearance notch corresponds to the end of the decorative shell that is finally tilted up.

[0058] Preferably, both sides of the clearance notch 54 are inclined surfaces extending in the circumferential direction, that is, the inclined surfaces on both sides extend in the counterclockwise direction and the clockwise direction respectively, and the greater the distance between the position where the two lower surfaces intersect and the base, the surface of the base 1 is also provided with a stop portion 16 protruding at the position corresponding to each decorative shell, and a stop groove 55 is formed between the two inclined surfaces of the clearance notch 54 to cooperate with the stop portion 16 to stop, that is, after rotation, the stop groove contacts the stop portion to form a stop (such as Figure 18As shown in FIG, the rotation stroke of the decorative shell is limited, thereby forming a double-point limit with the limit structure between the limit portion and the arc groove, thereby improving the reliability of the structure; of course, the side of the stop portion away from the stop groove is also a slope, one is to cooperate with the slope at the clearance notch to facilitate the rotation of the decorative shell, and the other is that when the decorative shell is rotated back to its original position, the slope on the stop portion cooperates with the slope on the clearance notch to make the settled end of the decorative shell continuously tilted up, and finally the tilted end of the decorative shell is retracted and the settled end is returned to the original height; it can also be understood that for the three decorative shells, three groups of lifting parts and stop parts are provided on the surface of the base, and the three groups of lifting parts and stop parts are on different circumferential lines (such as Figure 10 shown).

[0059] The technical solutions provided by the embodiments of the present invention are introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention.
