[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] It should be noted that the terms "first", "second" and "one end" in the specification and claims of the utility model are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, products or devices.

[0034] See also Figure 1 and Figure 3 The embodiment of the utility model provides an aromatherapy device 10. The aromatherapy device 10 comprises: a first shell 12 and a second shell 14. The second shell 14 is disposed in the first shell 12. The second shell 14 is provided with an aromatherapy accommodating cavity 142, and the first shell 12 is sleeved on the outer side of the second shell 14 facing away from the aromatherapy accommodating cavity 142.

[0035] In the aromatherapy device 10, the second shell 14 is used to contain aromatherapy materials, and the aromatherapy materials can be liquid materials such as essential oils, or solid materials such as perfume. Since the aromatherapy materials are placed in the aromatherapy accommodating chamber 142 in the second shell 14, and the second shell 14 separates the aromatherapy accommodating chamber 142 from the first shell 12, the aromatherapy materials will not come into contact with the first shell 12, and further, will not corrode the first shell 12. When the second shell 14 cannot be used after being used for a long time due to corrosion of the aromatherapy materials, the user can replace the second shell 14 to continue using the aromatherapy device 10. In addition, see Figure 1 and Figure 4aSince the first shell 12 is the outer shell relative to the second shell 14, the first shell 12 will not be deformed or cracked due to the corrosion of the aromatherapy material during the long-term use of the aromatherapy device 10. Therefore, the appearance of the aromatherapy device 10 will also maintain a good appearance during use due to the setting of the second shell 14. In summary, the aromatherapy device 10 provided in the embodiment of the utility model achieves the technical effect of protecting the outer shell of the aromatherapy device 10 during use by providing a second shell 14 having an aromatherapy accommodating chamber 142 and connected to the first shell 12, and using the second shell 14 to separate the first shell 12 and the aromatherapy accommodating chamber 142. Therefore, the appearance of the aromatherapy device 10 will not be affected by the corrosion of the aromatherapy material, thereby ensuring that the aromatherapy device 10 is stable and unchanged for the user during use, extending the service life of the aromatherapy device, and ensuring the user's experience.

[0036] Further, see Figure 3 and Figure 4a In the aromatherapy device 10, the first shell 12 may be, for example, a light-transmitting shell, and the second shell 14 may be, for example, a light-blocking shell. The first shell 12 may be, for example, a transparent or translucent material, and the second shell 14 may be a non-transparent material. The first shell 12 being a light-transmitting shell can make the aromatherapy device 10 more beautiful. The second shell 14 is a light-blocking shell, thereby preventing sunlight from passing through the first shell 12 and directly shining on the aromatherapy material in the aromatherapy accommodating cavity 142 through the second shell 14. When light is irradiated on the aromatherapy material, it will accelerate the decomposition of the fragrance molecules, thereby reducing the durability and fragrance intensity of the aromatherapy material. Moreover, for volatile fragrance components, light irradiation will cause them to evaporate faster, thereby reducing the durability of the fragrance. Therefore, the second shell 14 is set to a non-transparent material to maintain the fragrance durability and fragrance intensity of the aromatherapy material in the aromatherapy accommodating cavity 142.

[0037] Further, see Figure 1 and Figure 3 The second shell 14 is detachably connected to the first shell 12. The detachable connection between the first shell 12 and the second shell 14 can be achieved, for example, by snapping, locking, magnetic attraction, etc. This achieves the technical effect of enabling the user to replace the inner shell of the aromatherapy device 10, so as to ensure the continuous use of the aromatherapy device 10.

[0038] Further, see Figure 4a and Figure 4b, the outer wall of the second shell 14 is provided with a protrusion 144; the inner wall of the first shell 12 is provided with a groove 122, and the protrusion 144 is clamped with the groove 122. Specifically, the protrusion 144 is, for example, an arc-shaped protrusion; the groove 122 is, for example, an arc-shaped groove, the side wall and the groove bottom of the groove 122 are connected to form an arc surface, and the protrusion 144 is used to clamp the groove 122. Further, the groove 122 opened on the inner side of the first shell 12 is as shown in FIG. Figure 5a As shown, the protrusion 144 formed on the outer side of the second shell 14 is as shown in FIG. Figure 5b As shown. The first shell 12 and the second shell 14 are generally made of plastic and have a certain elasticity. Therefore, by providing the protrusion 144 and the groove 122, when the second shell 14 is installed in the first shell 12, the two shells can be installed smoothly through the elastic deformation of the two shells, that is, the protrusion 144 is smoothly engaged in the groove 122, and the above-mentioned arc structure also facilitates the separation of the first shell 12 and the second shell 14. The cross-section of the groove 122 can be, for example, Figure 5a The C-shaped structure. By providing the arc structure, the two shells are detachably connected through a mechanical structure, thereby avoiding the need to connect the first shell 12 and the second shell 14 by gluing or the like.

[0039] In addition, the groove 122 may be, for example, a continuous annular groove on the inner side wall of the first shell 12, or may be composed of a plurality of discrete grooves surrounding the inner side wall of the first shell 12. The protrusion 144 formed on the outer side of the second shell 14 may also adopt the same structural setting as the groove 122, and needs to match the groove 122, so as to achieve a detachable connection between the first shell 12 and the second shell 14.

[0040] Furthermore, the edge of the groove 122 is a smooth curved surface, and the smooth curved surface is protruding toward the inside of the first shell 12. The edge of the groove 122 is set as a smooth curved surface protruding toward the inside of the first shell 12, which can limit the position of the protrusion 144 in the groove 122 and thereby prevent the protrusion 144 from automatically detaching from the groove 122. Specifically, the setting of the smooth curved surface can, for example, make the protrusion 144 fit with the side wall of the groove 122 when it is in the groove 122.

[0041] Further, see Figure 3 and Figure 4a The aromatherapy device 10 further includes a cover 16. The cover 16 is detachably connected to the second shell 14 and / or the first shell 12, and covers the aromatherapy accommodating cavity 142. Figure 4aAs shown, the cover 16 cooperates with the first shell 12 and the second shell 14 to define the space of the aromatherapy chamber 142, and thus can define the aromatherapy material contained in the aromatherapy chamber 142. The aromatherapy material can be, for example, a solid material, and emits fragrance outward in the form of volatilization. The cover 16 can be provided with a fragrance diffusion hole 168, and the fragrance can diffuse outward through the fragrance diffusion hole 168. Specifically, the cover 16 can be connected to both the first shell 12 and the second shell 14, or connected to the first shell 12 or the second shell 14.

[0042] Furthermore, the cover 16 is magnetically connected to the second shell 14. Thus, the cover 16 and the second shell 14 are detachably connected. Figure 4a and Figure 4b The cover 16 is connected to the second shell 14 and is provided with a first magnetic member 162 on one side thereof; the second shell 14 is provided with a second magnetic member 146. The second magnetic member 146 is provided around the aromatherapy accommodating cavity 142, and the first magnetic member 162 is magnetically connected to the second magnetic member 146. The first magnetic member 162 and the second magnetic member 146 can be, for example, two magnet structures, or a combination of a magnet and a magnetically absorbable metal structure. Figure 8 The second magnetic member 146 may be configured as a ring structure to avoid the aromatherapy accommodating cavity 142 , and correspondingly, the first magnetic member 162 may also be configured as a ring structure to match the second magnetic member 146 .

[0043] Further, see Figure 4b , a first mounting groove 164 is provided on one side of the cover body 16 connected to the second shell 14, and the first magnetic member 162 is disposed in the first mounting groove 164. The second shell 14 can be provided with a similar structure. That is, a second mounting groove 148 is provided on one side of the second shell 14 connected to the cover body 16, and the second magnetic member 146 is disposed in the second mounting groove 148. Thus, the first magnetic member 162 and the second magnetic member 146 are respectively disposed in the cover body 16 and the second shell 14 through the groove structure.

[0044] Further, see Figure 4b, when the second shell 14 is provided with the first mounting groove 164, the groove bottom and / or side wall of the first mounting groove 164 is provided with a first glue groove 166, and the first magnetic member 162 is glued and connected to the cover body 16. Correspondingly, when the second shell 14 is provided with the second mounting groove 148, the groove bottom and / or side wall of the second mounting groove 148 is provided with a second glue groove 149, and the second magnetic member 146 is glued and connected to the second shell 14. Therefore, the first magnetic member 162 and the second magnetic member 146 can be set in their respective groove structures by gluing, and the setting of the first glue groove 166 and the second glue groove 149 can prevent glue from overflowing the first mounting groove 164 and the second mounting groove 148, respectively. In the aromatherapy device provided in the embodiment of the utility model, the first mounting groove 164 or the second mounting groove 148 can be set separately, or the first mounting groove 164 and the second mounting groove 148 can be set at the same time; and according to the existence of the two mounting groove designs, the first glue groove 166 and the second glue groove 149 can be correspondingly set.

[0045] Specifically, the first magnetic member 162 and the second magnetic member 146 can be encapsulated in their respective mounting grooves, for example, by Mylar packaging. Fig. 9 As shown, the first magnetic attraction member 162 is, for example, a ring magnet, and can be disposed in the first mounting groove 164 , and then encapsulated in the first mounting groove 164 through a Mylar sheet 167 .

[0046] In addition, see Figure 6b The aromatherapy device 10 may further include an aroma sheet 18. The aroma sheet 18 may be accommodated in the aromatherapy accommodating cavity 142, and the aroma sheet 18 is a multi-layer sheet structure. The aroma sheet 18 is made of aromatherapy essential oil and is a solid material. The multi-layer sheet structure of the aroma sheet 18 can increase its contact area with the atmosphere and achieve a better aroma diffusion effect.

[0047] Further, see Figure 7 , a protrusion 165 is formed on one side of the cover 16 connected to the second shell 14, and the protrusion 165 is connected to the inner wall of the second shell 14. Specifically, the protrusion 165 may be, for example, an annular protrusion. The protrusion 165 is connected to the inner wall of the second shell 14, and when the aromatherapy accommodating cavity 142 is in use, the connection surface between the cover 16 and the second shell 14 is generally consistent with the direction of gravity, so as to prevent the second shell 14 and the cover 16 from falling off due to insufficient magnetic attraction. In addition, the protrusion 165 can also be used to clamp solid aromatherapy materials. The solid aromatherapy material is, for example, Figure 6bThe scent sheet 18 shown, or other solid materials such as gypsum, scented wood, silica gel, etc. mixed with aroma raw materials. Taking the scent sheet 18 as an example, when the protrusion 165 is a ring-shaped protrusion, when the user uses the aroma device 10, the user can first clamp the scent sheet 18 in the protrusion 165. At this time, the aroma device 10 is as follows Figure 6a and Figure 7 Then the cover 16 connected with the scent sheet 18 is installed on the second shell 14 and the first shell 12. At this time, the aromatherapy device 10 is as shown in FIG. Figure 1 or Figure 4a shown.

[0048] Further, see Figure 2 The aromatherapy device 10 further includes a limiting clip 11. The limiting clip 11 is connected to the cover 16, and the limiting clip 11 is used to limit the aromatherapy device 10 to the environmental structure. Figure 1 The cover 16 includes a connecting portion 161 and an arc-shaped cover 163. The connecting portion 161 is used to connect the second shell 14. The arc-shaped cover 163 is bent to a side away from the connecting portion 161, and a plurality of fragrance diffusion holes 168 are provided on the arc-shaped cover 163. The fragrance diffusion holes 168 are preferably strip-shaped holes, and the shape of the holes is not limited here; the plurality of fragrance diffusion holes 168 are arranged side by side on the cover 16.

[0049] Further, see Figure 6b The aromatherapy device 10 includes an aroma sheet 18, which can be accommodated in the aromatherapy accommodating cavity 142. The aroma sheet 18 is provided with a plurality of sub-sheets (not shown), which are connected side by side and spaced apart from each other. The gaps between the sub-sheets correspond to the aroma diffusion holes 168. The fragrance emitted by each sub-sheet is diffused from the gaps between the sub-sheets and diffused to the aromatherapy device 10 through the strip-shaped aroma diffusion holes 168 corresponding to the gaps, so that the aroma diffusion effect is better.

[0050] exist Figure 1 In the aromatherapy device 10 shown in the figure, the user can pass the rope through the arc-shaped cover 163 through the aromatherapy hole 168, and hang the other end of the rope on an environmental structure such as a car rearview mirror, so as to hang the aromatherapy device 10 for use. Figure 2 In the illustrated case, the aromatherapy device 10 can be clamped on an environmental structure by means of a limiting clamp 11 , and the environmental structure can be, for example, an air-conditioning outlet of a vehicle.
