Detailed Implementation

[0024] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0025] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] refer to Figure 1-5 This utility model provides an adjustable concentration car fragrance diffuser, including a front cover 1, a rear cover 2, and an adjustment disc 3. The front cover 1 and the rear cover 2 are connected to form a receiving cavity 10 for placing fragrance chips 11. The adjustment disc 3 is rotatably connected to the side of the rear cover 2 near the front cover 1, and at least part of the adjustment disc 3 extends out of the receiving cavity 10, thus allowing the user to directly rotate and adjust the adjustment disc 3. The rear cover 2 has a diffuser opening 20, and the adjustment disc 3 has an adjustment opening 30 corresponding to the diffuser opening 20. The term "corresponding" mainly means that the opening and closing positions of the two are mutually corresponding. The rear cover 2 has a first adjustment part, and the adjustment disc 3 has a second adjustment part that matches and connects to the first adjustment part. The first adjustment part and the second adjustment part can be used to adjust whether the diffuser opening 20 and the adjustment opening 30 overlap or are staggered.

[0028] The working principle of the car air freshener provided by this utility model is as follows:

[0029] In use, the fragrance pad can be placed in the receiving cavity 10. The connection state between the first and second adjustment parts can be adjusted by rotating the adjustment disc 3. In this embodiment, the first and second adjustment parts have at least three connection states along the rotation direction of the adjustment disc 3, thereby controlling the size of the overlapping area between the diffuser 20 and the adjustment port 30. Specifically, when it is necessary to adjust the concentration of the fragrance, the user can control the rotation of the adjustment disc 3 by rotating the part of the adjustment disc 3 that extends out of the receiving cavity 10. When the first and second adjustment parts are in the first connection state, this is the initial state, and the fragrance diffuser is in the closed state, that is, the diffuser 20 and the adjustment port 30 are misaligned. By rotating the adjustment disc 3, the first and second adjustment parts are in the second connection state. At this time, the diffuser 20 and the adjustment port 30 overlap, that is, the diffuser 20 and the adjustment port 30 are connected, and the air conditioner vent can direct the air into the receiving cavity 10. Air is blown into the cavity 10, causing the fragrance of the scented tablet 11 to diffuse into the car's interior environment. When the adjustment disc 3 is rotated further, the first and second adjustment parts are in a third connection state. At this time, the overlapping area between the diffuser 20 and the adjustment port 30 reaches its maximum, that is, the connection area between the diffuser 20 and the adjustment port 30 is the largest. At this time, the air volume in the cavity 10 also reaches its maximum, so the fragrance concentration in the car can also reach its highest level. When it is necessary to turn off the fragrance diffuser, simply rotate the adjustment disc 3 in the opposite direction to return the connection state between the first and second adjustment parts to the initial state.

[0030] The adjustable concentration car fragrance diffuser provided by this utility model has the following advantages compared with the prior art:

[0031] The adjustment disc 3 is rotatably connected to the rear cover 2. The structure is simple. By rotating the adjustment disc 3, the overlapping area between the diffuser 20 and the adjustment port 30 can be controlled, thereby controlling the amount of air blown into the accommodating cavity 10, thus achieving a controllable concentration effect. Users can control the concentration of the fragrance according to the actual situation in the car, further enhancing the user experience.

[0032] In a preferred embodiment, a limiting groove 21 is also provided on the rear cover 2, and the extending direction of the limiting groove 21 is set along the rotation direction of the adjusting plate 3, or in other words, the limiting groove 21 extends along the circumferential direction of the rear cover 2; the adjusting plate 3 is provided with an adjusting block 31, which extends out of the receiving cavity 10, and the adjusting block 31 can rotate within the limiting groove 21. When the adjusting block 31 rotates, it can control the adjusting port 30 to coincide with or be offset from the aroma diffuser port 20. In this embodiment, by setting the limiting groove 21, on the one hand, it can facilitate the rotation of the adjusting plate 3 and make quick adjustments; on the other hand, it can also play a limiting role.

[0033] In a preferred embodiment, a first positioning shaft 22 is provided on the side of the rear cover 2 near the front cover 1. The first positioning shaft 22 protrudes towards the front cover 1. A sleeve hole 32 is provided on the adjusting plate 3, and the adjusting plate 3 is sleeved on the positioning shaft through the sleeve hole 32. A first adjusting part is provided on the first positioning shaft 22, and a second adjusting part is provided on the inner wall of the sleeve hole 32. At least one of the first adjusting part and the second adjusting part is a protrusion 23, and the other is a groove 33. The protrusion 23 and the groove 33 are matched and connected.

[0034] In a further preferred embodiment, there are multiple slots 33 or protrusions 23, which are spaced apart along the rotation direction of the adjusting disk 3. Referring to the figure, in this embodiment, there are three slots 33 and one protrusion 23. The three slots 33 are spaced apart along the circumferential direction on the inner wall of the through hole, and the protrusion 23 is located on the outer wall of the first positioning shaft 22. By rotating the adjusting disk 3, the protrusion 23 can be respectively engaged in the three slots 33, thereby corresponding to the three connection states mentioned above, and thus giving the fragrance diffuser three adjustable states: the first state is the fragrance diffuser closed (at which time the diffuser opening 20 and the adjusting opening 30 are offset), the second state is the fragrance diffuser half-open (at which time the diffuser opening 20 and the adjusting opening 30 partially overlap), and the third state is the fragrance diffuser fully open (at which time the diffuser opening 20 and the adjusting opening 30 completely overlap). In another embodiment, there can be one slot 33 and three protrusions 23, and the principle is the same as described above, which will not be repeated here. This design allows users to quickly and easily adjust the desired fragrance concentration, making it very convenient to use. Simultaneously, the interaction between the protrusion 23 and the slot 33 ensures that the adjustment disc 3 is relatively fixed when mounted on the first positioning shaft 22, preventing it from slipping out and improving stability.

[0035] In a preferred embodiment, there are multiple diffuser openings 20 and multiple adjustment openings 30. The multiple diffuser openings 20 are spaced apart along the circumferential direction of the rear cover 2; the multiple adjustment openings 30 are spaced apart along the circumferential direction of the adjustment disc 3. By providing multiple diffuser openings 20 and adjustment openings 30, the diffusion speed of the fragrance diffuser can be accelerated, and the diffusion effect can be better.

[0036] In a preferred embodiment, the position, shape, and size of each aroma diffuser 20 correspond to each adjustment port 30. That is, the position and shape of the aroma diffuser 20 and the adjustment port 30 are adapted to each other.

[0037] In a preferred embodiment, a first positioning shaft 22 is provided on the side of the rear cover 2 near the front cover 1, and a first connecting member 24 is provided on the first positioning shaft 22; a second positioning shaft 12 corresponding to the first positioning shaft 22 is provided on the second positioning shaft 12, and a second connecting member 13 is provided on the second positioning shaft 12. The front cover 1 and the rear cover 2 can be connected through the first connecting member 24 and the second connecting member 13. In this embodiment, the front cover 1 and the rear cover 2 can be detached and connected through the first connecting member 24 and the second connecting member 13, thereby facilitating the user to replace the incense stick 11 or the adjustment disc 3 at any time, making disassembly and assembly convenient.

[0038] In a preferred embodiment, the first connector 24 and the second connector 13 are magnetically connected. In this embodiment, both the first connector 24 and the second connector 13 are magnetic (such as magnets); in another embodiment, one of the first connector 24 and the second connector 13 is magnetic and the other is metal, also utilizing the principle of magnetic attraction to facilitate quick installation of the front cover 1 and the rear cover 2. Compared to the conventional threaded connection method on the market, this magnetic connection method is more conducive to increasing the product's service life. Specifically, with the conventional threaded connection method, as the usage time increases, especially with frequent air conditioning use in summer, the replacement frequency of the air conditioner 11 also increases. Frequent disassembly and reassembly of the front cover 1 and the rear cover 2 can lead to wear of the threads, resulting in loosening of the connection between the front cover 1 and the rear cover 2, thus affecting the product's service life.

[0039] In a preferred embodiment, at least one positioning hole 14 is provided on the front cover 1 or the rear cover 2, and a positioning pin 25 is provided on the other. The positioning pin 25 can be inserted into the positioning hole 14 to fix the front cover 1 and the rear cover 2. That is, in addition to being connected by magnetism, the front cover 1 and the rear cover 2 are further fixed by the cooperation between the positioning pin 25 and the positioning hole 14, which improves the overall stability of the fragrance diffuser. In this embodiment, multiple positioning holes 14 and positioning pins 25 are provided, respectively located on the periphery of the front cover 1 and the rear cover 2, making the connection between the front cover 1 and the rear cover 2 tighter and more aesthetically pleasing.

[0040] In a preferred embodiment, a fixing clip 26 is provided on the side of the back cover 2 away from the front cover 1 (i.e., the side closer to the air conditioner vent). The fixing clip 26 is detachably connected to the back cover 2. Specifically, the back cover 2 has a slot 27, and the end of the fixing clip 26 near the back cover 2 has an insert 260. The insert 260 can be inserted into the slot 27 to connect and fix the two. The fixing clip 26 is mainly used to fix the entire fragrance diffuser at the air conditioner vent. Since the fixing clip 26 is mainly clamped at the air vent, it will also wear down over time. By using a detachable connection, if the fixing clip 26 is damaged, the user can easily replace it at any time without having to replace the entire fragrance diffuser, thus reducing costs.

[0041] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
