Description

Technical Field

[0001] This utility model relates to the field of aromatherapy equipment technology, specifically to an aroma diffuser. Background Technology

[0002] An aroma diffuser is a common electronic product that atomizes essential oils, diffusing them into the air to improve the atmosphere, aid sleep, or achieve other health benefits. Traditional aroma diffusers typically have a complex structure, generally consisting of an outer shell, inner lining, inner chamber, and essential oil bottle nested together.

[0003] In this traditional structure, the airflow generated by the air pump needs to go through a tortuous path: first, the airflow enters the gap between the liner and the inner liner, then flows into the gap between the inner liner and the essential oil bottle through the connecting hole set on the side wall of the inner liner, and enters the atomizing cap upwards, and finally atomizes the essential oil at the atomizing cap.

[0004] However, since the top of the inner liner is usually open, users can easily and accidentally pour liquid essential oil directly into it when adding oil. Once the essential oil is poured in, the liquid quickly floods and blocks the connecting hole on the side wall of the inner liner. This completely interrupts the airflow path generated by the air pump, preventing it from reaching the atomizing cap and causing the aroma diffuser to completely lose its atomizing function. This not only affects the user's normal experience, but also makes cleaning extremely difficult due to the essential oil clogging the inside of the machine, often leading to product returns or even complete disposal. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a diffuser that optimizes the airflow path of the diffuser, preventing the airflow path from being submerged by essential oils, thereby improving the reliability and fault tolerance of the product.

[0006] To achieve this objective, the present invention adopts the following technical solution: A diffuser includes a housing, the interior of which forms an accommodating space; The inner liner is disposed within the accommodating space of the outer shell, and a second flow channel gap for gas passage is formed between the outer side wall of the inner liner and the inner side wall of the outer shell. The atomizing cap has a connecting hole on the top side wall of the inner liner. The second flow channel gap communicates with the atomizing cap through the connecting hole to allow gas to flow into the atomizing cap.

[0007] As a preferred embodiment of the diffuser, it further includes a mounting base and an air pump. The mounting base is disposed within the accommodating space of the outer shell, and the mounting base has an accommodating space inside. The air pump is disposed within the accommodating space of the mounting base. The inner liner is fixed to the mounting base by a connector, and a gap is left between the inner liner and the mounting base to form a first flow channel gap. The first flow channel gap communicates with the second flow channel gap. A through hole is opened on the mounting base near the inner liner. The output end of the air pump is located in the through hole of the mounting base to allow gas to flow into the first flow channel gap.

[0008] As a preferred embodiment of the diffuser, a first sealing ring is provided between the top outer wall of the mounting base and the inner wall of the outer shell to prevent gas leakage in the first flow channel gap; a second sealing ring is provided between the top outer wall of the inner liner and the inner wall of the outer shell to prevent gas leakage in the second flow channel gap.

[0009] As a preferred embodiment of the diffuser, the top outer wall of the mounting base is provided with a first groove, and the first sealing ring is installed in the first groove and tightly fitted with the inner wall of the outer shell; the top outer wall of the inner liner is provided with a second groove, and the second sealing ring is installed in the second groove and tightly fitted with the inner wall of the outer shell.

[0010] As a preferred embodiment of the diffuser, the inner liner includes an annular body and a base plate, the base plate being sealed to one end of the annular body, and the connector being fastened to the base plate.

[0011] As a preferred embodiment of the diffuser, the inner sidewall of the top of the outer casing extends horizontally inward to form an annular step, and the outer sidewall of the top of the annular core extends horizontally outward to form a folded edge. The folded edge is mounted on the annular step and fits tightly against the inner sidewall of the outer casing for fixation.

[0012] As a preferred embodiment of the aroma diffuser, the atomizing cover includes a cover body and an atomizing core. The outer wall of the cover body is provided with a first external thread. The cover body is threadedly connected to the inner liner through the first external thread. The cover body is provided with a pressurizing channel. The pressurizing channel extends horizontally outward and communicates with the connecting hole of the inner liner. The atomizing core is connected to the pressurizing channel.

[0013] As a preferred embodiment of the aroma diffuser, the atomizing core is provided with an air chamber and an essential oil chamber. The air chamber is connected to the pressurization channel to allow gas to enter, and the air chamber is provided with an air nozzle for the gas to be sprayed out.

[0014] As a preferred embodiment of the diffuser, the inner liner has a accommodating space, and an essential oil bottle containing essential oil is disposed within the accommodating space. The outer wall of the cap is provided with a second external thread, and the cap is threadedly connected to the essential oil bottle through the second external thread. An oil suction tube is disposed inside the essential oil bottle, and the oil suction tube is connected to the essential oil chamber of the atomizing core. The essential oil chamber is provided with an oil outlet. The air nozzle is adjacent to the oil outlet, and their axes are intersecting, so that the airflow ejected from the air nozzle can draw the essential oil out of the oil outlet through air pressure and collide with it at high speed to form an essential oil mist.

[0015] As a preferred embodiment of the diffuser, the atomizing cover is connected to an atomizing head, the cover body is provided with an exhaust channel, the atomizing head is provided with a gas collecting chamber communicating with the exhaust channel, and the top of the atomizing head is also provided with a mist outlet, which is connected with the gas collecting chamber to allow essential oil mist to flow out into the external environment.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) This utility model fundamentally solves the industry problem of diffuser failure due to misoperation by improving the internal airtight structure of the diffuser and cleverly increasing the inlet height of the connecting hole of the inner liner. Even if the user accidentally pours essential oil into the inner liner, the inlet of the connecting hole will not be submerged in most cases due to its high position. The gas generated by the air pump can still smoothly enter the atomizing cover through the connecting hole to achieve continuous atomization, which greatly improves the reliability and fault tolerance of the product.

[0017] (2) This utility model simplifies the airflow path of the diffuser. The airflow generated by the air pump flows through the first flow channel gap between the mounting base and the inner liner, to the second flow channel gap between the outer shell and the inner liner, and finally directly reaches the atomizing cover through the connecting hole, creating a shorter and smoother airflow path. This airflow path effectively reduces the airflow resistance, enabling the gas to reach the atomizing area more efficiently and quickly, thereby improving the atomization efficiency and the amount of mist output.

[0018] (3) The inner liner of this utility model abandons the traditional inner liner limiting structure, so that the inner liner has a larger accommodating space. This design frees the product from the constraints of a single capacity specification, and can flexibly adapt to inner liners of various sizes, thus improving the versatility of the product.

Detailed Implementation

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0030] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figures 1 to 3 As shown, this utility model provides a diffuser, including a shell 1, an inner liner 2, an atomizing cover 3, a mounting base 4, and an air pump 5. The shell 1 has an internal accommodating space, and both the mounting base 4 and the inner liner 2 are disposed within this space. The mounting base 4 also has an internal accommodating space, and the air pump 5 is disposed within this space. The inner liner 2 is fixed to the mounting base 4 by a connector 6, and a gap is left between the inner liner 2 and the mounting base 4 to form a first flow channel gap 7. A second flow channel gap 8 is formed between the outer side wall of the inner liner 2 and the inner side wall of the shell 1. The first flow channel gap 7 and the second flow channel gap 8... When the air pump 5 is working, the gas generated will first enter the first flow channel gap 7 and then enter the second flow channel gap 8 along the first flow channel gap 7. Since the top side wall of the inner liner 2 is also provided with a connecting hole 23, the second flow channel gap 8 is connected to the atomizing cover 3 through the connecting hole 23. Therefore, the gas can directly enter the atomizing cover 3 along the second flow channel gap 8 and the connecting hole 23, thereby simplifying the airflow path of the diffuser. This airflow path is not only shorter and smoother, but also effectively reduces airflow resistance, so that the gas can reach the atomizing area more efficiently and quickly, improving the atomization efficiency and mist output of the diffuser.

[0033] Meanwhile, in this embodiment, the connection hole 23 of the inner liner 2 is located on the top side wall, cleverly increasing the inlet height of the connection hole 23 of the inner liner 2. This fundamentally solves the industry problem of diffuser failure due to misoperation. Even if the user accidentally pours essential oil into the inner liner 2, because the connection hole 23 is positioned high, its inlet will not be submerged in most cases. The gas generated by the air pump 5 can still smoothly enter the atomizing cover 3 through the connection hole 23, achieving continuous atomization and greatly improving the reliability and fault tolerance of the product.

[0034] It should be noted that, in order to ensure that the gas from the air pump 5 can enter the first flow channel gap 7, this embodiment has a through hole in the mounting base 4 near the inner liner 2, and the output end of the air pump 5 is located in the through hole of the mounting base 4 so that the gas can flow into the first flow channel gap 7.

[0035] like Figure 4 As shown, since this embodiment simplifies the airflow path of the diffuser, the airtight structure of this embodiment is also changed accordingly. In this embodiment, a first sealing ring 9 is provided between the top outer wall of the mounting base 4 and the inner wall of the outer shell 1, thereby ensuring that the gas generated by the air pump 5 can only flow into the second flow channel gap 8 through the first flow channel gap 7, and cannot flow away into the gap between the mounting base 4 and the outer shell 1.

[0036] Similarly, in this embodiment, a second sealing ring 10 is provided between the top outer wall of the inner liner 2 and the inner wall of the outer shell 1, so as to ensure that the gas in the second flow channel gap 8 can only flow into the atomizing cover 3 through the connecting hole 23, and cannot flow out into the gap between the atomizing cover 3 and the outer shell 1.

[0037] It should be noted that, in order to install the first sealing ring 9 and the second sealing ring 10, a first groove 41 is provided on the top outer side wall of the mounting base 4 in this embodiment. The first sealing ring 9 is installed in the first groove 41, so as to better fix the first sealing ring 9 to the outer side of the mounting base 4. At the same time, the first sealing ring 9 is tightly fitted with the inner side wall of the outer shell 1 to achieve the gas sealing effect. Similarly, a second groove 24 is provided on the top outer side wall of the inner liner 2, and the second sealing ring 10 is installed in the second groove 24, so as to better fix the second sealing ring 10 to the outer side of the inner liner 2. At the same time, the second sealing ring 10 is tightly fitted with the inner side wall of the outer shell 1, thereby achieving the gas sealing function.

[0038] like Figure 5 and Figure 6 As shown, the inner liner 2 specifically includes an annular liner 21 and a bottom plate 22. The bottom plate 22 is sealed to one end of the annular liner 21, and the connector 6 is fastened to the bottom plate 22.

[0039] It should be noted that the connector 6 described in this embodiment can be a bolt. By opening a hole in the top of the mounting base 4 and opening a threaded groove on the side of the base plate 22 near the mounting base 4, the bolt passes through the mounting base 4 and is threadedly connected to the threaded groove of the base plate 22, thereby achieving a fast connection. Similarly, the connector 6 described in this embodiment can also be a plug rod. By opening a hole in the top of the mounting base 4 and opening a slot on the side of the base plate 22 near the mounting base 4, the plug rod passes through the mounting base 4 and engages with the slot of the base plate 22 to achieve a fast connection.

[0040] It is understood that the connector 6 described in this embodiment is not limited to the connection methods listed above, and can also be connected by other fastening methods, as long as there is a gap between the base plate 22 and the mounting base 4. These will not be described in detail here.

[0041] In this embodiment, the inner liner 2 abandons the traditional inner liner limiting structure, allowing the inner liner 2 to have a larger accommodating space within the outer shell 1. This design frees the product from the constraints of a single capacity specification, enabling it to flexibly adapt to inner liners 2 of various sizes, thus improving the product's versatility.

[0042] like Figure 2 As shown, in order to achieve the connection between the inner liner 2 and the outer shell 1, the top inner wall of the outer shell 1 in this embodiment extends inward horizontally to form an annular step 11, and the top outer wall of the annular liner 21 extends outward horizontally to form a folded edge 25. The folded edge 25 is mounted on the annular step 11 and fits tightly against the inner wall of the outer shell 1 to achieve fixation, thereby limiting the relative position of the inner liner 2 in the axial and radial directions.

[0043] like Figure 7 As shown, the atomizing cap 3 includes a cap body 31 and an atomizing core 32. The outer wall of the cap body 31 is provided with a first external thread 311. The first external thread 311 is integrally formed with the cap body 31. The cap body 31 is threadedly connected to the inner liner 2 through the first external thread 311. A pressurization channel 313 is provided inside the cap body 31. The pressurization channel 313 extends horizontally outward and communicates with the connection hole 23 of the inner liner 2. At the same time, an air chamber 321 and an essential oil chamber 322 are provided inside the atomizing core 32. The air chamber 321 is connected to the pressurization channel 313. The gas in the second flow channel gap 8 is pressurized through the pressurization channel 313 and enters the air chamber 321. The air chamber 321 is also provided with an air nozzle 323. High-pressure gas can be ejected at high speed from the air nozzle 323 of the air chamber 321.

[0044] Meanwhile, the inner liner 2 also has a storage space inside, within which is placed an essential oil bottle 12 for holding essential oils. The outer wall of the cap 31 has a second external thread 312, which is integrally formed with the cap 31. The cap 31 is threadedly connected to the essential oil bottle 12 via the second external thread 312. An oil suction tube 13 is installed inside the essential oil bottle 12, communicating with the essential oil chamber 322 of the atomizing core 32. The essential oil chamber 322 is equipped with an oil outlet 324. During the high-speed ejection of gas from the nozzle 323, according to Bernoulli's principle, the faster the fluid velocity... The lower the lateral pressure, the better. This is because the high-speed airflow will pull the air in the essential oil chamber 322 out of the oil outlet 324, creating a low-pressure area in the essential oil chamber 322. Under the action of air pressure, the essential oil in the essential oil bottle 12 will enter the essential oil chamber 322 through the oil suction tube 13 and flow out from the oil outlet 324. Since the air nozzle 323 and the oil outlet 324 are adjacent and their axes are intersecting, the high-speed airflow ejected from the air nozzle 323 can spray the essential oil flowing out of the oil outlet 324, causing the essential oil to collide and shear violently with the high-speed airflow, thereby being atomized into ultrafine particles.

[0045] It should be noted that, in this embodiment, the oil nozzle 324 and the air nozzle 323 are preferably set at 90° vertically, which is more conducive to the collision between the high-speed airflow and the essential oil, resulting in higher atomization efficiency.

[0046] In this embodiment, the atomizing cover 3 is also connected to an atomizing head 14. An exhaust channel 314 is provided inside the cover 31, and an air collecting chamber 141 communicating with the exhaust channel 314 is provided inside the atomizing head 14. A mist outlet 142 is also provided at the top of the atomizing head 14. The mist outlet 142 is communicating with the air collecting chamber 141. The atomized essential oil will enter the air collecting chamber 141 through the exhaust channel 314 and finally flow out into the external environment through the mist outlet 142, thereby realizing the aromatherapy function.

[0047] It is understood that the housing 1 in this embodiment also houses components such as a controller and a battery pack. Furthermore, the housing 1 has several control buttons, which are electrically connected to the controller inside the housing 1 via wires to achieve intelligent control of the diffuser. This invention does not involve improvements to these structures and will not be elaborated upon here.

[0048] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
