Description

Technical Field

[0001] This utility model relates to the field of aromatherapy equipment technology, and in particular to an aromatherapy machine. Background Technology

[0002] With the increasing popularity of aromatherapy devices, the ease of use and leak-proof performance of essential oil bottles, as the core carriers for atomizing essential oils, have become crucial indicators affecting user experience. Traditional essential oil bottles typically employ a direct-flow first spray hole design, where the first spray hole is directly connected to the internal liquid storage chamber of the bottle, and the essential oil is atomized and sprayed out through the airflow generated by the atomizer. However, this design has a significant drawback: when the essential oil bottle is tilted, inverted, or accidentally knocked over during transportation or use, the liquid essential oil inside the bottle is very likely to spill directly out along the first spray hole under the influence of gravity. This not only wastes essential oil but also contaminates the internal circuit components of the device and the surrounding desktop environment. Long-term residual essential oil may also corrode the device's outer casing, affecting its lifespan.

[0003] Therefore, how to construct a stable gas-liquid isolation barrier has become a technical challenge that urgently needs to be overcome in this field. Utility Model Content

[0041] This utility model proposes an aroma diffuser for installing an essential oil bottle 40 to spray atomized essential oil.

[0042] In the embodiments of this utility model, such as Figures 1 to 7 As shown, the aroma diffuser includes: a main body, wherein the main body is provided with a first spray hole 111;

[0043] Atomizing assembly, wherein the essential oil bottle 40 is detachably mounted on the atomizing assembly, and the atomizing assembly is disposed within the main body; and

[0044] A flow guide 30 is disposed between the first spray hole 111 and the atomizing component. The flow guide 30 includes a first flow guide channel 31 and a second flow guide channel 32 that are interconnected. The first flow guide channel 31 is arc-shaped and the horizontal cross-section of the inner sidewall of the first flow guide channel 31 is higher than the liquid level in the essential oil bottle 40. The end of the first flow guide channel 31 away from the second flow guide channel 32 is provided with a mist inlet 311 that communicates with the atomizing component. The end of the second flow guide channel 32 away from the first flow guide channel 31 is provided with a mist outlet 321 that communicates with the first spray hole 111.

[0045] Aroma diffusers are used to atomize and spray essential oils. The main body is the mounting structure of the aroma diffuser, which houses the internal components and provides installation space.

[0046] The atomizing assembly is used to atomize essential oils. The essential oil bottle 40 is detachably mounted on the atomizing assembly so that users can change to different types of essential oils or add more. The atomizing assembly generally consists of an atomizer 22 and an air pump 23. The air pump 23 provides airflow, which atomizes the essential oil under the action of the atomizer 22 and sprays it out through the guide 30.

[0047] The flow guide 30 is used to optimize the airflow path and prevent essential oil leakage. The first flow guide channel 31 has an arc-shaped design, and the horizontal cross-section of its inner wall is higher than the liquid level in the essential oil bottle 40. It should be explained that the horizontal cross-section of the inner wall of the first flow guide channel 31 refers to the horizontal cross-section of the inner wall at the highest point of the first flow guide channel 31 when the aroma diffuser is tilted during transportation or use. Due to the arc-shaped design of the first flow guide channel 31, the essential oil cannot flow directly into the second flow guide channel 32 under the action of gravity, thus preventing the essential oil from overflowing through the first spray hole 111, thereby achieving the anti-leakage function. The mist inlet 311 is connected to the atomizing component and is used to guide the atomized essential oil into the flow guide 30, while the mist outlet 321 is connected to the first spray hole 111, so that the essential oil is smoothly sprayed out after atomization, improving the atomization effect.

[0048] This utility model's aroma diffuser includes a main body, an atomizing component housed within the main body, and a flow guide 30 connecting the atomizing component and a first spray hole 111. The atomizing component is used to detachably mount an essential oil bottle 40 and atomize the essential oil. The flow guide 30 includes a first flow guide channel 31 and a second flow guide channel 32 that are interconnected. The first flow guide channel 31 is arc-shaped, and the horizontal section of its inner wall is higher than the liquid level in the essential oil bottle 40. The end of the first flow guide channel 31 away from the second flow guide channel 32 has a mist inlet 311, which communicates with the atomizing component. The end of the second flow guide channel 32 away from the first flow guide channel 31 has a mist outlet 321, which communicates with the first spray hole 111. Through this structural design, when the aroma diffuser is tilted, inverted, or subjected to impact, the arc-shaped arrangement of the first flow guide channel 31 ensures that the inner wall of the flow guide 30 is always higher than the liquid level in the essential oil bottle 40, thereby preventing essential oil from overflowing along the flow guide 30 and effectively preventing equipment damage and environmental pollution caused by essential oil leakage. Therefore, it effectively improves the leak-proof performance and practicality of the aroma diffuser.

[0049] Furthermore, such as Figures 1 to 6 As shown, the first flow channel 31 is arranged in a ring shape, and the mist outlet 321 is positioned close to the central axis of the flow guide 30 relative to the mist inlet 311. In this embodiment, the ring-shaped design of the first flow channel 31 makes the boundary of the flow guide 30 more uniform, thereby ensuring that the inner wall of the flow guide 30 remains higher than the liquid level in the essential oil bottle 40 regardless of the direction or angle from which the aroma diffuser is tilted, preventing the essential oil in the aroma diffuser from overflowing due to tilting, and further realizing the anti-leakage function.

[0050] Furthermore, the placement of the mist outlet 321 near the central axis relative to the mist inlet 311 creates an angle between the first guide channel 31 and the second guide channel 32. This design further limits essential oil leakage. When the aroma diffuser is tilted or inverted, the angled design effectively prevents essential oil from flowing into the second guide channel 32, thus avoiding overflow through the mist outlet 321. This structure optimizes leak-proof performance, ensuring the reliability and long-term stable use of the aroma diffuser.

[0051] Furthermore, the mist outlet 321 is located at the center of the airflow guide 30. In this embodiment, positioning the mist outlet 321 at the center of the airflow guide 30 optimizes the spray direction of the atomized essential oil, allowing the atomized essential oil to be sprayed evenly and stably from the center. This design helps to evenly distribute the airflow after the essential oil is atomized, thereby improving the atomization effect and ensuring that the atomized essential oil in the aromatherapy diffuser can cover a wider area.

[0052] Furthermore, the mist inlet 311 and the mist outlet 321 are arranged opposite to each other along the axial direction of the guide member 30. It should be explained that the axial direction opposite to each other means that the opening directions of the mist inlet 311 and the mist outlet 321 are arranged on opposite sides of the first guide channel 31.

[0053] Furthermore, such as Figures 1 to 4 As shown, the first spray hole 111 is located on the top surface of the main body. In this embodiment, the first spray hole 111 is located on the top surface of the main body, which enables the atomized essential oil to be sprayed upwards evenly and stably, thereby purifying the environment around the main body, effectively enhancing the reliability and effectiveness of the aromatherapy diffuser, and improving the user experience.

[0054] Furthermore, such as Figures 1 to 4 As shown, the main body includes a mounting shell 12 and a cover 11 detachably connected to the mounting shell 12. The atomizing component is mounted on the cover 11, and the first spray hole 111 is located at the top of the cover 11. The essential oil bottle 40 is located inside the mounting shell 12. In this embodiment, the detachable connection between the cover 11 and the mounting shell 12 allows users to easily disassemble and clean the internal components of the aromatherapy diffuser. Specifically, the atomizing component is mounted on the cover 11, facilitating user replacement of the essential oil bottle 40 and routine maintenance. Simultaneously, the first spray hole 111, located at the top of the cover 11, ensures that the atomized essential oil can be smoothly sprayed from the top, avoiding clogging or obstruction of the spray. The essential oil bottle 40, located inside the mounting shell 12, helps stabilize the storage and supply of essential oil, ensuring the reliability and stability of the aromatherapy diffuser during use.

[0055] Furthermore, such as Figures 1 to 6As shown, the cover 11 is provided with a rectifier cavity 112, and the guide member 30 is disposed within the rectifier cavity 112. The atomizing component and the mist inlet 311 are both connected to the rectifier cavity 112. In this embodiment, the design of the rectifier cavity 112 can effectively balance and guide the airflow, ensuring that the atomized essential oil can smoothly enter the guide member 30. By placing the guide member 30 within the rectifier cavity 112, the flow path of the essential oil airflow can be optimized, reducing turbulence in the airflow and thus improving atomization efficiency.

[0056] In addition, the connection between the atomizing component and the mist inlet 311 and the rectifier cavity 112 helps the airflow to transition smoothly, so that the atomized essential oil can enter the guide component 30 evenly and stably and be sprayed out through the mist outlet 321, which effectively improves the atomization effect of the aroma diffuser and enhances the stability and overall performance of the aroma diffuser.

[0057] Furthermore, such as Figures 1 to 5 As shown, a fixing post 113 protrudes from the periphery of the first spray hole 111 within the rectifying cavity 112, and the mist outlet 321 of the guide member 30 is fitted onto the fixing post 113. In this embodiment, the fixing post 113 is used to fix the guide member 30, ensuring that the mist outlet 321 is stably positioned within the rectifying cavity 112 and preventing displacement or loosening during use. By fitting the mist outlet 321 onto the fixing post 113, a stable spray path for the essential oil airflow is ensured, improving the atomization effect and the accuracy of essential oil spraying. The first spray hole 111 penetrates the fixing post 113 and communicates with the guide member 30.

[0058] Furthermore, such as Figures 1 to 4 As shown, the atomizing assembly includes a first mounting bracket 21, an atomizer 22 fixedly mounted on the first mounting bracket 21, and an air pump 23 disposed within the mounting housing 12. One end of the atomizer 22 is connected to the liquid in the essential oil bottle 40 via a conduit 41, and the other end is connected to the air pump 23. The cover 11 has a mounting groove 114, and the first mounting bracket 21 is fixedly disposed within the mounting groove 114. A flow-rectifying cavity 112 is formed between the first mounting bracket 21 and the inner wall of the mounting groove 114. The first mounting bracket 21 has a second spray hole 211 connecting the flow-rectifying cavity 112 and the essential oil bottle 40. In this embodiment, the atomizing assembly is stably mounted via the first mounting bracket 21, and the atomizer 22 is connected to the liquid in the essential oil bottle 40 via the conduit 41, ensuring that the essential oil can be supplied to the atomizer 22 for atomization in a timely manner. The air pump 23 provides airflow support to the atomizer 22, promoting the atomization and spraying of the essential oil.

[0059] Secondly, the design of the mounting groove 114 allows the first mounting bracket 21 to be securely installed on the cover 11, and the space between the first mounting bracket 21 and the inner wall of the mounting groove 114 forms a rectifier cavity 112. The rectifier cavity 112 optimizes the airflow path, reduces turbulence in the airflow, and improves atomization efficiency. The design of the second spray hole 211 allows for a smooth connection between the rectifier cavity 112 and the essential oil bottle 40, ensuring that the essential oil can be effectively supplied to the atomizer 22 for atomization.

[0060] Furthermore, such as Figures 1 to 4 and Figure 7 As shown, the atomizing assembly further includes a second mounting bracket 24 disposed within the mounting housing 12. The second mounting bracket 24 has a receiving groove 241 for accommodating the essential oil bottle 40. The first mounting bracket 21 and the second mounting bracket 24 interlock to form a sealed cavity 25. The air pump 23 is disposed on the second mounting bracket and communicates with the sealed cavity 25. The first mounting bracket 21 has an airflow channel 212, one end of which communicates with the atomizer 22, and the other end of which communicates with the sealed cavity 25. In this embodiment, the second mounting bracket 24 provides a receiving groove 241 for the essential oil bottle 40, effectively fixing the position of the essential oil bottle 40 and ensuring that the essential oil bottle 40 does not shift during use. The first mounting bracket 21 and the second mounting bracket 24 interlock to form a sealed cavity 25. The design of the sealed cavity 25 can effectively isolate external air and airflow path, ensuring the stability of airflow and the atomization effect of essential oil during atomization.

[0061] An air pump 23 is mounted on a second mounting bracket 24 and communicates with a sealed cavity 25, enabling the atomizer 22 to atomize essential oils via airflow provided by the air pump 23. An airflow channel 212 opened in the first mounting bracket 21 is connected to the atomizer 22 at one end and to the sealed cavity 25 at the other end, which facilitates smooth airflow and ensures that the essential oils are atomized and sprayed out through the atomizer 22.

[0062] Specifically, the atomizer 22 includes a first channel 221 and a second channel 222. One end of the first channel 221 is connected to the airflow channel 212, and the other end is open towards the inside of the essential oil bottle 40 and close to the end of the second channel 222. The other end of the second channel 222 is connected to a conduit 41 extending into the inside of the essential oil bottle 40. The end of the second channel 222 close to the first channel 221 is used to spray out the liquid in the essential oil bottle 40. The axes of the first channel 221 and the second channel 222 are perpendicular to each other.

[0063] In use, the air pump 23 pressurizes the sealed cavity 25. After the air enters the airflow channel 212, it enters the essential oil bottle 40 through the first channel 221 of the atomizer 22, increasing the air pressure inside the essential oil bottle 40. This causes the essential oil liquid inside the essential oil bottle 40 to be forced into the conduit 41 and then flow into the second channel 222 and exit from the end of the second channel 222 near the first channel 221. Since the first channel 221 and the second channel 222 are opposite and perpendicular, the air blown into the essential oil bottle 40 by the air pump 23 and the essential oil liquid meet at the adjacent ends of the first channel 221 and the second channel 222, causing the essential oil liquid to be dispersed and atomized into an essential oil mist. The essential oil mist moves upward, flows through the second spray hole 211 into the rectifier cavity 112, and then exits through the guide 30 and the first spray hole 111.

[0064] Furthermore, such as Figures 1 to 4 As shown, a check valve 50 is also provided in the airflow channel 212. In this embodiment, the check valve 50 is installed in the airflow channel 212 to prevent the airflow from flowing backward. When the air pump 23 is working, the airflow in the airflow channel 212 is forced to pass through the atomizer 22 for atomization, and the check valve 50 can prevent the airflow or essential oil from flowing back into the sealed cavity 25 and contaminating the device, thereby improving the performance and stability of the aromatherapy diffuser.

[0065] Furthermore, such as Figures 1 to 4 As shown, an anti-overflow ball valve 60 is provided on the side of the second spray hole 211 facing the essential oil bottle 40. In this embodiment, the anti-overflow ball valve 60 is a valve with a spherical structure, installed near the second spray hole 211 and facing the essential oil bottle 40. The function of the anti-overflow ball valve 60 is to prevent essential oil from overflowing through the second spray hole 211 due to gravity when the aromatherapy diffuser is tilted or inverted.

[0066] The spherical structure inside the anti-overflow ball valve 60 can be freely adjusted according to changes in liquid pressure, preventing essential oils from overflowing due to external forces. When the aroma diffuser is in normal working condition, the anti-overflow ball valve 60 is open, allowing the atomized essential oils to flow smoothly through the second spray hole 211 and out through the guide member 30. However, when the aroma diffuser is tilted at too large an angle or inverted, the anti-overflow ball valve 60 will automatically close, preventing essential oil leakage, ensuring that the inside of the aroma diffuser remains clean, and preventing external environmental contamination by essential oils. This improves the practicality of the aroma diffuser.

[0067] At the same time, with the help of the guide component 30, the aroma diffuser is effectively guaranteed not to leak from any angle, thus effectively improving the practicality of the aroma diffuser.

[0068] Furthermore, such as Figures 1 to 4As shown, the atomizing component also includes a flow divider 27, which is disposed within the rectifying cavity 112 and corresponds to the second spray hole 211. In this embodiment, the function of the flow divider 27 is to differentiate the airflow path, thereby effectively distributing the atomized essential oil through the second spray hole 211, making the atomized essential oil more evenly distributed in the rectifying cavity 112, avoiding uneven or overly concentrated airflow, which would affect the atomization effect of the aroma diffuser. This design further improves the atomization efficiency and stability of the aroma diffuser.

[0069] Furthermore, such as Figures 1 to 3 As shown, the aroma diffuser also includes a control component, which includes a main control board 71 and a battery 72 electrically connected to the main control board 71. The main control board 71 is electrically connected to the air pump 23. In this embodiment, the control component intelligently controls the working state of the aroma diffuser, ensuring that the diffuser can operate efficiently and stably. The main control board 71 is the core control component of the aroma diffuser. It is powered by the battery 72 and electrically connected to the air pump 23, controlling the start and stop of the air pump 23 and its working intensity. When the user turns on the aroma diffuser, the main control board 71 controls the working state of the air pump 23 by receiving the user's operation commands (such as turning on, turning off, adjusting the atomization intensity, etc.), thereby achieving the atomization effect of essential oils.

[0070] Battery 72 provides the necessary power for the entire system, ensuring the independent operation of the aroma diffuser. Through the electrical connection between the main control board 71 and the air pump 23, the operating mode of the aroma diffuser can be flexibly adjusted, enhancing the user experience.

[0071] Furthermore, such as Figures 1 to 6 As shown, the flow guide 30 is a one-piece molded structure. In this embodiment, the flow guide 30 adopts a one-piece molded design, which allows the flow guide 30 to be formed by an integral mold during the production process, avoiding the splicing of multiple parts, thereby improving the overall stability and sealing of the structure. Specifically, the flow guide 30 can be made into a one-piece molded structure using blow molding or ultrasonic welding, and there is no limitation on this.

[0072] like Figure 8 and Figure 9 As shown, in another embodiment, the flow guide 30 may further include an upper housing 33 and a lower housing 34 that are interlocked with each other. The upper housing 33 and the lower housing 34 are provided with partitions 35 for forming a flow guide channel. The mist inlet 311 is opened on the lower housing 34, and the mist outlet 321 is opened on the upper housing 33.

[0073] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
