[0001] This utility model relates to the field of air outlet aromatherapy devices, and more particularly to an air outlet aromatherapy device. Background Technology

[0002] Vent diffusers are common fragrance devices that are clipped and positioned at the air vents of cars. They work by using the principle of air vents to guide some of the gas into the diffuser to create a fragrance effect.

[0003] In vent-type aromatherapy diffusers, some use scented blocks or breathable membrane diffusers as the source of fragrance. Breathable membrane diffusers only diffuse fragrance from one side, which is not very efficient. While the outer surface of the scented block itself is the source of fragrance, the current structure of vent-type aromatherapy diffusers, such as setting an air outlet on one side, makes insufficient use of the fragrance diffusion surface of the scented block, resulting in low fragrance diffusion efficiency. Summary of the Invention

[0004] This invention provides an air vent aromatherapy diffuser, which aims to solve the problem of insufficient fragrance diffusion efficiency of existing air vent aromatherapy diffusers.

[0005] According to an embodiment of this application, an air outlet aromatherapy diffuser is provided, including a base, an aromatherapy component, and an air guide plate. The aromatherapy component is disposed on the base, and the air guide plate covers the aromatherapy component within the base. The aromatherapy component includes an internal portion and a protruding portion. The internal portion is arranged around the outer periphery of the protruding portion, and the internal portion is located between the base and the air guide plate, with its side abutting against the inner side of the base. The protruding portion protrudes towards the side away from the base, and extends outwards into the central area of ​​the air guide plate. The base... An air inlet is provided at the bottom of the base, and a recessed first and second drainage groove are provided on the inner surface of the base. The first drainage groove is connected to the air inlet and the second drainage groove respectively. The second drainage groove bends and extends from the bottom of the base to the top side.

[0030] 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, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0032] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0033] Please combine Figure 1 , Figure 2 , Figure 3 and Figure 4 The first embodiment of this utility model discloses an air outlet aromatherapy diffuser, including a base 1, an aromatherapy component 2 and an air guide plate 3. The aromatherapy component 2 is disposed on the base 1, and the air guide plate 3 covers the aromatherapy component 2 inside the base 1.

[0034] The aromatherapy component 2 includes a built-in portion 21 and a protruding portion 22. The built-in portion 21 is arranged around the outer periphery of the protruding portion 22. The built-in portion 21 is located between the base 1 and the air guide plate 3, and the side of the built-in portion 21 abuts against the inner side of the base 1. The protruding portion 22 protrudes towards the side away from the base 1, and the protruding portion 22 extends outward and exposes the central area of ​​the air guide plate 3. That is, the air guide plate 3 is arranged around the outer periphery of the protruding portion 22, and the air guide plate 3 covers the built-in portion 21 inside the base 1.

[0035] It is understood that the aromatherapy component 2 is a solid perfume paste that is molded in one piece, and its outer surface, including the outer surface of the inner part 21 and the protruding part 22, is made of solid perfume paste material that can be used to diffuse fragrance.

[0036] The base 1 has an air inlet 101 at its bottom, and its inner surface has a recessed first drainage groove 102 and a second drainage groove 103. The first drainage groove 102 communicates with both the air inlet 101 and the second drainage groove 103. The second drainage groove 103 extends from the bottom of the base 1 inwards to the top. Figure 2As shown, the second drainage groove 103 forms a connected L-shaped groove structure on the inner surface of the base 1, including the bottom surface and the side surface of the base 1, and extends to the top of the base 1. The air inlet 101, the first drainage groove 102 and the second drainage groove 103 are connected in sequence.

[0037] The air guide plate 3 has a through groove 31 at the top position corresponding to the second flow channel 103 (e.g., Figure 4 As shown in the diagram, the through groove 31 extends outward from the side of the protrusion 22, and a first air outlet 104 is formed between the through groove 31 and the side of the base 1. The air guide plate 3 has a second air outlet 32 ​​at the end of the through groove 31 near the protrusion 22. Figure 4 As shown in direction a, the airflow entering from the first guide channel 102 moves upward from the direction of the second guide channel 103. When it passes through the through channel 31, the airflow is split, with one stream blowing outward toward the first air outlet 104 (that is, blowing out toward the side of the aromatherapy diffuser). Figure 4 (In the direction of ab), another airflow flows along the channel 31 toward the protrusion 22, and blows upward from the second air outlet 32 ​​(that is, blows toward the top of the aroma diffuser, such as...). Figure 4 (in the AC direction), forming aromatherapy airflow in two directions.

[0038] It can be understood that the number of first drainage channels 102 and second drainage channels 103 is one or more. The number of multiple second drainage channels 103 corresponds one-to-one with the number of through channels 31 and the number of first air outlets 104. One first drainage channel 102 can connect to multiple second drainage channels 103 and multiple air inlets 101. The number of first drainage channels 102 corresponds one-to-one with the number of air inlets 101, and the side of one first drainage channel 102 connects to multiple second drainage channels 103. Figure 2 As shown, the base 1 is provided with four first drainage channels 102, each of which is connected to an air inlet 101, and each of which is connected to four or five second drainage channels 103.

[0039] It can be understood that the aromatherapy gas is output in two directions formed by the airflow moving along the ab and ac directions. The airflow starts from the first guide groove 102 and contacts the bottom of the built-in part 21. Then the airflow enters the second guide groove 103 and contacts the side of the built-in part 21. Then the airflow enters the through groove 31 and contacts the top surface of the built-in part 21. Finally, when it is discharged from the second air outlet 32, it can still contact the outer surface of the protrusion 22. This achieves multi-area coverage of the outer surface of the aromatherapy component 2, improves the fragrance diffusion efficiency, makes the fragrance diffusion on the surface of the aromatherapy component 2 more uniform, and makes full use of the multiple fragrance diffusion surfaces of the aromatherapy component 2 for fragrance diffusion.

[0040] Furthermore, please combine Figure 5 and Figure 6 The protrusion 22 is provided with an inwardly recessed notch 221 at the position corresponding to the second air outlet 32, and the notch 221 extends from the position near the second air outlet 32 ​​toward the top of the protrusion 22.

[0041] It is understandable that when the airflow flows upward from the second air outlet 32 ​​along the surface of the protrusion 22, the notch 221 can further increase the surface area of ​​contact between the airflow and the surface of the protrusion 22, thereby further improving the fragrance diffusion efficiency of the aroma diffuser 2. At the same time, the notch 221 can utilize the area on the side of the protrusion 22 to form another channel for gas flow, allowing the diffused gas to flow outward more evenly.

[0042] Please continue to combine Figure 1 and Figure 4 The air vent aromatherapy diffuser of this application also includes a top cover 4, which covers the outer periphery of the air guide plate 3 away from the base 1. The protrusion 22 and the second air outlet 32 ​​are exposed on the top cover 4, so that the middle area of ​​the top cover 4 forms a recessed structure. The gap between the outer periphery of the protrusion 22 and the inner periphery of the top cover 4 forms an annular cavity. When the second air outlet 32 ​​blows out gas, a flow straightening wall can be formed based on the annular cavity to guide the gas from the second air outlet 32 ​​to blow along the protruding direction of the protrusion 22.

[0043] Optionally, as one embodiment, the inner edge of the top cover 4 is flush with the edge of the second air outlet 32. The distance between the inner surface of the top cover 4 and the protrusion 22 gradually increases from the bottom to the top, forming a sloping structure to increase the coverage of the outward blowing airflow and increase the diffusion area of ​​the aromatherapy gas.

[0044] Alternatively, as another embodiment, the top cover 4 is made of transparent material, and the inside of the top cover 4 is sealed with liquid and suspended matter, specifically water and gold foil fragments to form a flowing "quicksand" effect; or it can be made of essential oil and plastic particles, which can also form a flowing dynamic effect and enhance the aesthetics.

[0045] Please combine Figure 2 and Figure 3 The air inlets 101 are located at opposite ends of the base 1. The airflow flows from opposite ends of the aromatherapy component 2 toward the middle. During the process, based on the guiding effect of the first guide groove 102, the airflow continuously flows to multiple second guide grooves 103 on the path and is blown out from the corresponding first air outlet 104 and second air outlet 32.

[0046] Please continue to combine Figure 3 and Figure 4The base 1 also has an opening 11, and a clamping part 12 is provided on the side of the base 1 opposite to the aromatherapy component 2. The clamping part 12 includes claws 121, a first connecting plate 122, and a second connecting plate 123. The claws 121 are respectively disposed on both sides of the opening 11, and the first connecting plate 122 connects the claws 121 on both sides of the opening 11. The second connecting plate 123 is located inside the opening 11 and is disposed corresponding to the first connecting plate 122. The middle area of ​​the second connecting plate 123 arches towards the aromatherapy component 2.

[0047] It is understandable that the clamping part 12 is made of plastic, the jaws 121 are used to clamp onto the fan blades of the car's air vent, the first connecting plate 122 is used to connect the jaws 121 on both sides of the opening 11, and the arched structure of the opening 11, in conjunction with the second connecting plate 123, facilitates the movement and clamping of the jaws 121.

[0048] Compared with the prior art, the air vent aromatherapy provided by this utility model has the following beneficial effects:

[0049] By setting an air guide plate to cover the aromatherapy unit inside the base, with the protruding part of the aromatherapy unit exposed on the air guide plate, a first flow channel is set inside the base to connect with a second flow channel. Together with the through channel and the second air outlet set on the air guide plate, a pipeline for forming gas flow inside the product is created. That is, when the gas enters the product and flows inside, the airflow is divided into two paths. The first path is based on the first and second flow channels and is discharged outward from the first air outlet, that is, the fragrance is diffused using the surface of the internal part. The second path is based on the first flow channel, the second flow channel, and the through channel, and continues to blow outward along the outer surface of the protruding part from the direction of the second air outlet, that is, further utilizing the surface of the protruding part to diffuse the fragrance. The result is that it can form fragrance diffusers in both the side and front of the product, and allow the airflow to flow completely over most of the surface of the aromatherapy unit, improving the fragrance diffusion efficiency and the utilization rate of the fragrance diffusion surface of the aromatherapy unit, and making the fragrance diffusion loss between different parts of the aromatherapy unit more uniform.

[0050] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
