Description

Technical Field

[0001] This utility model relates to the field of in-vehicle fragrance products, and in particular to a novel smart fragrance box. Background Technology

[0002] There are two main types of car air fresheners (or fragrance diffusers): one type does not require electricity and uses cotton wicks, rattan, corks, etc. to allow the fragrance to evaporate naturally or diffuse through the car's ventilation vents; the other type uses external power to heat and evaporate the fragrance or uses a miniature fan to diffuse it.

[0003] Chinese utility model patent (application number CN2025203594908) discloses a smart car fragrance diffuser, which is an air freshener that does not require electricity and allows fragrance to evaporate naturally. The invention concept involves a counterweight sleeve, a counterweight block, and a spring acting as a piston within a sliding cavity. Vibration during vehicle operation causes the counterweight to slide up and down, propelling the fragrance diffuser. While this patent has many advantages, it still has the following shortcomings:

[0004] (1) The spring force and the counterweight should be in force balance. When this product is used in high-end cars, the vehicle will be more stable due to the good shock absorption system. The amplitude of up and down sliding will be small and the aroma will be less emitted.

[0005] (2) Because the spring and counterweight will tilt and sway when sliding up and down, the sliding resistance is large, which again affects the amount of aroma emission.

[0006] (3) After long-term use, the sliding cavity and counterweight sleeve are prone to wear.

[0007] To address the aforementioned shortcomings of this patent, this solution proposes a novel smart fragrance box. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of the utility model patent application number CN2025203594908 in the background art. The specific solution is as follows:

[0009] A novel smart fragrance box, installed in a vehicle, includes an upper shell and a lower shell. The upper shell has a cover assembly at its top and a jumping cavity inside. The jumping cavity contains a counterweight assembly, and the counterweight assembly and the interior of the upper shell are equipped with a magnetic levitation mechanism. The lower shell contains a fragrance assembly. The interior of the lower shell, the interior of the upper shell, and the cover assembly are equipped with fragrance delivery channels. During vehicle operation, the counterweight assembly loses its balance with its own weight and the magnetic thrust of the magnetic levitation mechanism due to vehicle vibration, causing it to jump up and down, which drives the fragrance in the fragrance delivery channels to be discharged upwards.

[0010] Furthermore, the magnetic levitation mechanism includes a first magnetic element disposed at the lower center of the counterweight assembly and a second magnetic element disposed at the bottom of the upper shell. The first magnetic element and the second magnetic element generate a mutually repulsive magnetic thrust, which is equal in magnitude to the weight of the counterweight assembly itself.

[0011] Furthermore, the first magnetic element and the second magnetic element are ring magnets.

[0012] Furthermore, the outer diameters of the first magnetic element and the second magnetic element may be equal or unequal.

[0013] Furthermore, the first magnetic element is embedded in the first circular slot at the lower center of the counterweight sleeve of the counterweight assembly.

[0014] Furthermore, the second magnetic element is embedded in the second circular slot at the center of the bottom of the upper shell.

[0015] Option 1:

[0016] Optionally, the magnetic levitation mechanism further includes a third magnetic element disposed on the peripheral surface of the counterweight assembly and a fourth magnetic element disposed on the inner surface of the upper shell. The third and fourth magnetic elements generate a repulsive magnetic force, which causes the center of the counterweight assembly to be located on the central axis of the upper shell. The third and fourth magnetic elements are ring magnets or multiple magnets arranged in a ring. The third magnetic element is wrapped in a third circular groove on the peripheral surface of the counterweight assembly or embedded in a third circular toothed groove on the peripheral surface of the counterweight assembly. The fourth magnetic element is tightly fitted onto multiple ribs on the inner wall of the upper shell or embedded in multiple toothed grooves on the inner wall of the upper shell. The outer diameter of the third magnetic element is smaller than the inner diameter of the fourth magnetic element, and there is a gap between the outer surface of the third magnetic element and the inner surface of the fourth magnetic element. The height of the third magnetic element is smaller than the height of the fourth magnetic element.

[0017] Option 2:

[0018] Optionally, the inner wall of the upper shell is a smooth surface, the peripheral surface of the counterweight assembly is a smooth surface, and a gap is provided between the peripheral surface of the counterweight assembly and the inner wall of the upper shell.

[0019] In summary, the technical solution of this utility model has the following beneficial effects:

[0020] Based on the background technology of Chinese Utility Model Patent Application No. CN2025203594908, this utility model improves the spring-type sliding mechanism into a magnetic levitation mechanism, which has the following advantages:

[0021] (1) The lower side and the surrounding area of ​​the counterweight component are subjected to magnetic thrust and are suspended in a state under the balance of its own weight and magnetic thrust. It is located at the center of the jumping cavity wall in the horizontal direction and will not touch the jumping cavity wall, so the friction is very small.

[0022] (2) Because the friction of the magnetic suspension counterweight component is very small, the counterweight component will jump with the slight vibration of the product, which greatly improves the jumping sensitivity and allows the perfume to be fully diffused inside the vehicle.

[0023] (3) Because this product has high magnetic levitation jumping sensitivity, it is more suitable for mid-to-high-end models with good shock absorption systems.

[0024] (4) Because the counterweight component is suspended and does not contact the wall of the jumping chamber, there is almost no friction and no mechanical noise is generated, so the product is more durable and has a longer service life.

[0025] (5) This solution uses a magnetic levitation mechanism, which has a simple structure and process, and is easy to assemble and mass-produce.

[0026] (6) Based on market and customer demand, for this product that reduces costs, the third and fourth magnetic components can be removed, and the inner wall of the upper shell and the peripheral surface of the counterweight assembly can be changed to a smooth surface.

Detailed Implementation

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0049] like Figures 1 to 12As shown, a novel smart fragrance box, installed in a vehicle, preferably in a cup holder, includes an upper shell 10 and a lower shell 20. The upper shell 10 has a cover assembly 30 on its upper part, and a vibration chamber 11 inside the upper shell 10. A counterweight assembly 40 is located within the vibration chamber 11. A magnetic levitation mechanism is provided within the counterweight assembly 40 and the upper shell 10. A fragrance component 50 is located inside the lower shell 20. Fragrance delivery channels are provided within the lower shell 20, the upper shell 10, and the cover assembly 30. During vehicle operation, the counterweight assembly 40 loses balance between its own weight and the magnetic thrust of the magnetic levitation mechanism due to vehicle vibration, causing it to bounce up and down, thus expelling the fragrance from the fragrance delivery channels upwards. The cover assembly 30 includes a cover 31, a fragrance intensity adjustment assembly 32 (including an adjustment disc 320, a silicone pad 321, an adjustment plate 322, a damping ring 323, a spring 324, and a retaining ring 325; the damping ring 323 can generally be omitted), and an upper anti-collision ring 33. The adjusting plate 322 and the groove 311 of the upper cover 31 are respectively provided with a pair of structurally matched waist-shaped leaf holes 300. A middle cover assembly 60 is provided between the upper shell 10 and the lower shell 20. The middle cover assembly 60 includes a middle cover 61, a decorative ring 62 on the outer ring of the middle cover 61, a middle cover sealing ring 63 on the upper end of the middle cover 61, and a diffusion cotton 64 inside the middle cover 61. The perfume assembly 50 includes a perfume bottle 51, perfume 52, absorbent cotton swab 53, and a bottle mouth sealing ring 54. The fragrance delivery channel includes an air inlet channel and an air outlet channel. The air inlet channel consists of multiple air inlet windows 21 on the peripheral wall of the lower shell 20 (the air inlet windows 21 are also perfume viewing windows), an air inlet valve composed of multiple spheres 65 and sphere grooves 66 inside the middle cover 61, a diffusion cotton 64, an air window 12 at the bottom of the upper shell 10, and the lower space of the jumping chamber 11. The air outlet channels are, in sequence, an absorbent cotton swab 53, a diffuser cotton 64, a central hole 13 and an air window 12 at the bottom of the upper shell 10, the lower space of the vibration chamber 11, the central one-way air outlet valve 41 of the counterweight assembly 40, the upper space of the vibration chamber 11, and the aroma intensity adjustment assembly 32. The vibration chamber 11 is divided into an upper space and a lower space by the counterweight assembly 40.

[0050] Specifically, the magnetic levitation mechanism includes a first magnetic element 42 located at the center of the lower side of the counterweight assembly 40 and a second magnetic element 14 located at the bottom of the inner shell 10. The first magnetic element 42 and the second magnetic element 14 generate a mutually repulsive magnetic thrust, which is equal to the weight of the counterweight assembly 40 itself.

[0051] Specifically, the first magnetic element 42 and the second magnetic element 14 are ring magnets.

[0052] Optionally, the outer diameters of the first magnetic element 42 and the second magnetic element 14 may be equal or unequal. The inner diameters of the first magnetic element 42 and the second magnetic element 14 may be equal or unequal. The thicknesses of the first magnetic element 42 and the second magnetic element 14 may be equal or unequal.

[0053] Specifically, the first magnetic element 42 is embedded in the first circular slot 431 at the lower center of the counterweight sleeve 43 of the counterweight assembly 40.

[0054] Specifically, the second magnetic element 14 is embedded in the second circular slot 15 at the bottom center of the upper shell 10.

[0055] Example 1:

[0056] like Figure 3 , 13 As shown, optionally, as a better embodiment, based on the previous specific implementation, this embodiment 1 further includes a third magnetic element 44 disposed on the peripheral surface of the counterweight assembly 40 and a fourth magnetic element 16 disposed on the inner surface of the upper shell 10. The third magnetic element 44 and the fourth magnetic element 16 generate a mutually repulsive magnetic thrust, which causes the center of the counterweight assembly 40 to be located on the central axis of the upper shell 10. Since both the upper shell 10 and the counterweight assembly 40 are cylindrical, they share a common central axis. The third magnetic element 44 and the fourth magnetic element 16 are ring magnets. The third magnetic element 44 is wrapped around the third circular groove 432 on the peripheral surface (i.e., the counterweight sleeve 43) of the counterweight assembly 40, and the fourth magnetic element 16 is tightly fitted onto multiple ribs 17 on the inner wall of the upper shell 10. The outer diameter of the third magnetic component 44 is smaller than the inner diameter of the fourth magnetic component 16, and there is a gap between the outer surface of the third magnetic component 44 and the inner surface of the fourth magnetic component 16. The height of the third magnetic component 44 is smaller than the height of the fourth magnetic component 16.

[0057] Example 2:

[0058] like Figure 14 As shown, the difference between Embodiment 2 and Embodiment 1 is that the third magnetic element 44 and the fourth magnetic element 16 are multiple magnetic blocks distributed in a ring (uniformly). The number of magnetic blocks in the third magnetic element 44 and the fourth magnetic element 16 are matched, with a minimum of four blocks and a preferred distribution of six or eight blocks. The third magnetic element 44 is embedded in the third toothed groove (not shown in the figure) on the peripheral surface of the counterweight assembly 40, and the fourth magnetic element 16 is embedded in multiple toothed grooves (not shown in the figure) on the inner wall of the upper shell 10. The rest is the same as in Embodiment 1 and will not be repeated here.

[0059] Example 3:

[0060] like Figure 15 As shown, the difference between Embodiment 3 and Embodiment 1 is that the third magnetic component 44 is a ring magnet, while the fourth magnetic component 16 consists of multiple magnetic blocks distributed in a ring (uniformly), preferably 6 or 8 blocks. The third magnetic component 44 is wrapped around the third circular groove 432 of the peripheral surface (i.e., the counterweight sleeve 43) of the counterweight assembly 40, and the fourth magnetic component 16 is embedded in multiple toothed grooves (not shown in the figure) on the inner wall of the upper shell 10. The rest is the same as in Embodiment 1 and will not be repeated here.

[0061] Example 4:

[0062] like Figure 16 As shown, the difference between Embodiment 4 and Embodiment 1 is that the third magnetic component 44 consists of multiple magnetic blocks distributed in a ring (uniformly), preferably 6 or 8 blocks. The fourth magnetic component 16 is a ring magnet. The third magnetic component 44 is embedded in the third toothed groove (not shown in the figure) on the peripheral surface of the counterweight assembly 40, and the fourth magnetic component 16 is tightly fitted onto multiple ribs 17 on the inner wall of the upper shell 10. The rest is the same as in Embodiment 1 and will not be repeated here.

[0063] Example 5:

[0064] like Figure 17 As shown, optionally, as a cost-reduction embodiment, the difference between this embodiment 5 and embodiment 1 is that the third magnetic component 44 and the fourth magnetic component 16 are omitted, and the inner wall of the upper shell 10 is a smooth surface, the peripheral surface of the counterweight component 40 is a smooth surface, and a gap is provided between the peripheral surface of the counterweight component 40 and the inner wall of the upper shell 10. The rest is the same as in embodiment 1, and will not be repeated here.

[0065] For ease of explanation, only Example 1 will be used here; the principles of the other examples are the same. The four annular magnets in this scheme (i.e., the first magnetic element 42, the second magnetic element 14, the third magnetic element 44, and the fourth magnetic element 16) are permanent magnets, and their magnetic poles are arranged as follows... Figure 18 As shown.

[0066] The one-way exhaust valve 41 of this design includes a circular valve plate 410, three evenly spaced sliding rods 411 extending downwards from the lower side of the valve plate 410, and outward hooks 412 at the lower end of the sliding rods 411. The sliding rods 411 and hooks 412 are inserted from top to bottom into the central circular hole 433 of the counterweight sleeve 43. The length of the sliding rods 411 is greater than the depth of the central circular hole 433, so that the valve plate 410 can move upwards away from the central circular hole 433 to open the valve and allow the aroma to be discharged upwards. To improve the sealing performance of the one-way exhaust valve 41, a valve rubber ring 413 is provided between the upper side of the valve plate 410 and the central circular hole 433. The counterweight assembly 40 of this design includes a counterweight block 45 located in the mounting groove 434 on the upper side of the counterweight sleeve 43.

[0067] The working process of this solution is briefly described as follows: Perfume 52 is adsorbed onto diffusion cotton 64 through absorbent cotton swab 53. During vehicle operation, the counterweight component 40 loses the balance between its own weight and the magnetic thrust of the magnetic levitation mechanism due to vehicle vibration, causing it to bounce up and down, which drives the fragrance in the fragrance delivery channel to be discharged upward. Specifically, when the counterweight component 40 bounces upward, an air intake process is generated. Under the action of negative pressure, outside air pushes the ball 65 through the air intake channel (see the detailed description above) into the space of the bounce chamber 11, and mixes with the perfume around the diffusion cotton 64, dispersing into the space of the bounce chamber 11. When the counterweight component 40 bounces downward, an exhaust process is generated. The counterweight component 40 compresses the fragrance in the space of the bounce chamber 11 and discharges it outward through the exhaust channel (see the detailed description above).

[0068] As can be seen from the accompanying drawings in this specification, this solution does not require screws; all components are connected by snap-fit ​​or threaded joints, which has the advantage of high assembly efficiency.

[0069] In summary, the technical solution of this utility model has the following beneficial effects:

[0070] Based on the background technology of Chinese Utility Model Patent Application No. CN2025203594908, this utility model improves the spring-type sliding mechanism into a magnetic levitation mechanism, which has the following advantages:

[0071] (1) The lower side and the surrounding area of ​​the counterweight component are subjected to magnetic thrust and are suspended in a state under the balance of its own weight and magnetic thrust. It is located at the center of the jumping cavity wall in the horizontal direction and will not touch the jumping cavity wall, so the friction is very small.

[0072] (2) Because the friction of the magnetic suspension counterweight component is very small, the counterweight component will jump with the slight vibration of the product, which greatly improves the jumping sensitivity and allows the perfume to be fully diffused inside the vehicle.

[0073] (3) Because this product has high magnetic levitation jumping sensitivity, it is more suitable for mid-to-high-end models with good shock absorption systems.

[0074] (4) Because the counterweight component is suspended and does not contact the wall of the jumping chamber, there is almost no friction and no mechanical noise is generated, so the product is more durable and has a longer service life.

[0075] (5) This solution uses a magnetic levitation mechanism, which has a simple structure and process, and is easy to assemble and mass-produce.

[0076] (6) Based on market and customer demand, for this product that reduces costs, the third and fourth magnetic components can be removed, and the inner wall of the upper shell and the peripheral surface of the counterweight assembly can be changed to a smooth surface.

[0077] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
