Description

Technical Field

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

[0002] Currently, aroma diffusers that employ the two-fluid atomization principle typically use compressed gas to break essential oils into tiny particles within a core atomizer to achieve diffusion. This process often utilizes Bernoulli's principle to generate negative pressure, enabling a continuous supply of essential oils and atomization circulation.

[0003] However, existing devices have significant shortcomings in practical applications. The air outlet and oil outlet of the core atomizer are extremely small, while essential oils have high surface tension and viscosity, easily leading to liquid backflow or adhesion, causing micropore blockage, thus reducing atomization effect and shortening duration. In addition, during long-term use, impurity deposition or device wear can also cause blockage or damage, leading to the failure of the entire device. Utility Model Content

[0004] The main purpose of this invention is to provide an atomizer, atomizing assembly, and an aromatherapy diffuser, which aims to prevent liquid backflow or adhesion to the atomizer, thereby improving the atomization effect of the atomizer.

[0005] To achieve the above objectives, this utility model proposes an atomizer, the atomizer comprising: The main body has an air intake channel, one end of which is an air outlet; and the end of the main body adjacent to the air outlet is also provided with a protective rim, which is located above or to the side of the air outlet to prevent backflow of essential oil liquid; and The liquid inlet pipe is connected to the main body and has a liquid inlet channel for assembly with the essential oil conduit. An oil outlet hole is provided at the end of the liquid inlet channel away from the essential oil conduit, and the oil outlet hole is located adjacent to the air outlet hole.

[0006] In one embodiment, the protective awning protrudes from the outer periphery of the main body.

[0007] In one embodiment, the protective rim protrudes from the outer periphery of the inlet pipe.

[0008] In one embodiment, the side of the protective eaves facing away from the liquid inlet pipe is a liquid guiding surface, which is inclined downward from the side adjacent to the main body to the side away from the main body.

[0009] In one embodiment, the main body is further provided with a mist outlet channel, which is connected to the outside and located above the liquid guiding surface.

[0010] This utility model also proposes an atomizing assembly, the atomizing assembly comprising: Essential oil bottle; and The atomizer described above is installed at the mouth of the essential oil bottle, and the liquid inlet channel of the atomizer is connected to the essential oil bottle.

[0011] This utility model also proposes an aroma diffuser, the aroma diffuser comprising: The outer casing has an inner cavity, a mounting cavity, and a mist outlet, wherein the mist outlet communicates with the mounting cavity, and the mounting cavity communicates with the inner cavity; A compression pump, the compression pump being installed in the inner cavity; and As described above, in the atomizing assembly, one end of the essential oil bottle of the atomizing assembly is detachably connected to the mounting cavity; the air intake channel of the atomizer of the atomizing assembly is connected to the compressor pump.

[0012] In one embodiment, the outer shell includes an upper shell and a lower shell detachably connected to the upper shell, and the mounting cavity is provided on the side of the lower shell facing away from the upper shell; a mounting flange is provided at one end of the bottle mouth of the essential oil bottle, the mounting flange is spaced apart from the bottle mouth of the essential oil bottle, and the outer wall of the mounting flange is threadedly connected to the side wall of the mounting cavity.

[0014] In one embodiment, a sealing gasket is installed between the bottom wall of the mounting cavity and the end of the mounting flange, and the sealing gasket abuts against the mouth of the essential oil bottle.

[0015] This atomizer utilizes a protective rim located above or to the side of the main body near the air outlet, creating a physical barrier that effectively blocks and guides backflow of essential oil during atomization. This completely prevents highly viscous essential oil from adhering to or clogging the delicate air and oil outlets. This key design ensures the long-term unobstructed flow of the atomizing micropores, allowing for continuous and stable mixing of the high-speed airflow and essential oil. This not only significantly improves the uniformity and efficiency of atomization but also fundamentally enhances the reliability and continuity of the atomizer's operation, ultimately achieving the core objective of preventing liquid backflow and ensuring and improving atomization performance.

[0023] Traditional two-fluid aroma diffusers, when atomizing essential oils, suffer from problems due to the small size of the air outlet and oil outlet of the core atomizer. The surface tension and viscosity of the essential oil are relatively high, which can easily cause the essential oil to flow back or adhere to the micropores, causing micropore blockage. This results in a decrease in atomization effect, a shortening of the duration, and even failure of the entire machine due to impurity deposition or device wear.

[0024] For this, please refer to Figures 1 to 3 This application proposes an atomizer 1, which includes a main body 10 and a liquid inlet tube 30. The main body 10 is provided with an air inlet channel 10a, one end of which is an air outlet 10b. The main body 10 is also provided with a protective rim 20 near the air outlet 10b, which is located above or to the side of the air outlet 10b and is used to block the backflow of essential oil liquid. The liquid inlet tube 30 is connected to the main body 10 and has an inlet channel 30a for assembly with an essential oil conduit. The end of the inlet channel 30a away from the essential oil conduit is provided with an oil outlet 30b, which is located near the air outlet 10b.

[0025] In this application, the atomizer 1 is mainly used for atomizing and diffusing essential oils. The main body 10 is the primary structural component of the atomizer 1, and various functional structures, such as channels, orifices, or additional components, can be integrated internally or externally. The main body 10 provides the physical carrier for realizing the core functions of the atomizer 1. The air inlet channel 10a is a passageway located inside or on the surface of the main body 10, used to guide gas into the atomizer 1. The structure and dimensions of this channel are designed to ensure the stability and efficiency of the airflow. The air outlet 10b is the end opening of the air inlet channel 10a through which gas is discharged and interacts with the liquid during atomization. The geometry and position of the air outlet 10b affect the atomization effect. The protective rim 20 is a protruding structure located on the main body 10, adjacent to the air outlet 10b. Its main function is to physically block or guide the backflow of essential oil liquid, preventing it from adhering to or clogging key orifices. The placement and shape of the protective rim 20 are crucial to achieving its blocking function. The liquid inlet tube 30 is a tubular component connected to the main body 10, used to guide liquid into the atomization area. The connection method and internal structure of the liquid inlet tube 30 are designed to ensure a smooth liquid supply. The liquid inlet channel 30a is a passageway inside the liquid inlet tube 30, used to carry and transport essential oils. The size and material of this channel are selected to suit the characteristics of the essential oils and ensure effective assembly with the essential oil conduit. The essential oil conduit is an external conduit used to transport essential oils from the storage container to the liquid inlet channel 30a of the atomizer 1. The connection between the essential oil conduit and the liquid inlet channel 30a ensures a continuous supply of essential oils. The oil outlet 30b is the end opening of the liquid inlet channel 30a through which essential oils are discharged and mixed with the airflow, thereby achieving atomization. The position and size of the oil outlet 30b, in conjunction with the air outlet 10b, affect atomization efficiency and particle size.

[0026] This application provides an atomizer 1, whose main body 10 is designed as the core structure of the atomizer 1, and has an air intake channel 10a inside. The air intake channel 10a can be a straight pipe, and its cross-sectional shape can be circular, square, or elliptical to guide airflow. One end of the air intake channel 10a forms an air outlet 10b, which can be a circular, slit-shaped, or other shaped opening for ejecting compressed gas. For example, the air outlet 10b can be a tiny circular hole formed directly on the wall of the main body 10, or a slit integrally formed by a mold.

[0027] A protective rim 20 is provided at one end of the main body 10 adjacent to the air outlet 10b. This protective rim 20 can be a thin, sheet-like protrusion extending from the surface of the main body 10, or an edge structure surrounding a portion of the air outlet 10b. The protective rim 20 is positioned above or to the side of the air outlet 10b. For example, the protective rim 20 can be a small shield located directly above the air outlet 10b, or a vertical baffle located to one side of the air outlet 10b. The protective rim 20 is designed to prevent backflow of essential oil during atomization, preventing it from directly adhering to the edge of the air outlet 10b or the oil outlet 30b, thereby avoiding blockage.

[0028] In addition, the atomizer 1 also includes an inlet tube 30, which is connected to the main body 10 to supply essential oils. This connection can be a plug-in, adhesive, or threaded connection. The inlet tube 30 has an inlet channel 30a inside, which can be an integrally formed inner cavity 3a with the inlet tube 30, or an independent tube inserted into the inlet tube 30. The inlet channel 30a is designed for assembly with an essential oil conduit; for example, the essential oil conduit can be directly inserted into the inlet of the inlet channel 30a, or connected to the inlet channel 30a via an adapter.

[0029] Specifically, the end of the liquid inlet channel 30a furthest from the essential oil conduit is provided with an oil outlet 30b. This oil outlet 30b can be the end opening of the liquid inlet channel 30a, and its size and shape can be designed according to atomization requirements, such as a tiny circular orifice. The oil outlet 30b is positioned adjacent to the air outlet 10b. For example, the oil outlet 30b can be positioned side-by-side with the air outlet 10b, or slightly lower than the air outlet 10b, to utilize the negative pressure effect of the airflow. This proximity ensures that the essential oil sprayed from the oil outlet 30b can effectively interact with the high-speed airflow sprayed from the air outlet 10b, thereby achieving effective atomization of the essential oil.

[0030] By providing a protective rim 20 near the air outlet 10b on the main body 10 and positioning it above or to the side of the air outlet 10b, the atomizer 1 effectively blocks the backflow of essential oil during atomization, preventing it from adhering to the tiny openings of the air outlet 10b or the oil outlet 30b. This design significantly reduces the risk of micropore clogging, avoids the problems of decreased atomization effect and shortened duration caused by essential oil backflow, thereby improving the stability and lifespan of the atomizer 1.

[0031] In some embodiments described above, the atomizer 1 is provided with a protective rim 20, which is located above or to the side of the air outlet 10b to prevent backflow of essential oil liquid. However, in actual use, the essential oil liquid may splash or condense during atomization. If the protective rim 20 fails to effectively form a barrier, some essential oil liquid may still flow back to an undesirable area, affecting the atomization effect or causing contamination.

[0032] For this, please refer to Figures 1 to 3 This application further proposes the above-mentioned atomizer 1, wherein the protective rim 20 protrudes from the outer periphery of the main body 10.

[0033] In this embodiment, the protective rim 20 protrudes from the outer periphery of the main body 10, meaning that the protective rim 20 structurally extends outward, exceeding the outer contour of the main body 10 in the corresponding area. This protruding design makes the protective rim 20 form a physical overhang or edge, which enhances the interception and guidance capabilities of essential oil droplets. Specifically, the protective rim 20 can be integrally formed and connected to the main body 10, or the protrusion can be achieved through additional structural components. The degree and shape of the protrusion can be optimized according to the specific structure of the atomizer 1 and the atomization characteristics of the essential oil to ensure that it can effectively cover and block potential essential oil backflow paths. For example, the protective rim 20 can be designed as a ring, semi-ring, or sheet structure, extending outward at a certain angle or arc, thereby forming an effective blocking surface above or to the side of the air outlet 10b.

[0034] By designing the protective rim 20 to protrude from the outer periphery of the main body 10, it forms a more significant physical barrier structure. When essential oil droplets generated during atomization, whether splashed or condensed, encounter the protective rim 20, its protruding structure effectively intercepts and guides these droplets away from the air outlet 10b and air inlet channel 10a. This prevents the essential oil from flowing back into the internal structure of the atomizer 1, thus ensuring the stability and purity of the atomization effect and effectively preventing the essential oil from contaminating or clogging the internal components of the atomizer 1, extending the service life of the device.

[0035] Please see Figures 1 to 3 This application further proposes a protective awning 20 protruding from the outer periphery of the inlet pipe 30.

[0036] Specifically, the protective rim 20 extends outward in the radial direction, beyond the outer boundary of the inlet pipe 30. This design allows the protective rim 20 to form a wider blocking area, effectively covering the external space of the inlet pipe 30. The protective rim 20 can be designed as a ring structure surrounding the inlet pipe 30, with an outer diameter larger than that of the inlet pipe 30, thus providing a physical barrier when the essential oil liquid may flow back along the outer wall of the inlet pipe 30.

[0037] Furthermore, the protective rim 20 can also be an arc-shaped structure partially surrounding the inlet pipe 30, with its protruding portion located in the direction in which the essential oil is most likely to flow back. The protruding portion of the protective rim 20 can be integrally formed with the inlet pipe 30, or it can be a separate component fixed to the inlet pipe 30 or the main body 10 by means of snaps, welding, or bonding, extending to the outer periphery of the inlet pipe 30. The degree of protrusion can be optimized according to the path and amount of essential oil backflow to ensure effective blocking.

[0038] Through the above technical solution, the protruding design of the protective rim 20 can more effectively intercept the essential oil liquid flowing back along the outer wall of the inlet pipe 30. This prevents the essential oil liquid from accumulating near the atomization area, thereby ensuring the stability and consistency of the atomization process and reducing the waste of essential oil. This design significantly enhances the overall effectiveness of the protective rim 20 in managing the flow of essential oil.

[0039] Please see Figures 1 to 3 Furthermore, this application proposes that the side of the protective eaves 20 facing away from the liquid inlet pipe 30 is a liquid guiding surface 20a, and the liquid guiding surface 20a is inclined downward from the side adjacent to the main body 10 to the side away from the main body 10.

[0040] Specifically, the side of the protective rim 20 facing away from the liquid inlet pipe 30 is designed as a liquid guiding surface 20a. This liquid guiding surface 20a is a surface on the protective rim 20 specifically designed to guide liquid flow. Its function is to collect and guide essential oil liquid blocked by the protective rim 20, allowing it to drain in an orderly manner and preventing disorderly accumulation. At the same time, the liquid guiding surface 20a is inclined downwards from the side adjacent to the main body 10 towards the side away from the main body 10. This inclined structure allows the essential oil liquid to flow naturally downwards along the liquid guiding surface 20a under the action of gravity, thereby effectively diverting the essential oil liquid away from key areas (such as near the air outlet 10b). The tilt angle can be optimized according to the viscosity of the essential oil, the installation direction of the atomizer 1, and the desired drainage efficiency. For example, it can be set to an angle of 5 degrees to 45 degrees with the horizontal plane to ensure that the essential oil liquid can drain smoothly and prevent stagnation.

[0041] Through the above technical solution, when the atomizer 1 is working, if essential oil flows back and is blocked by the protective rim 20, this essential oil will fall onto the liquid guiding surface 20a of the protective rim 20. Since the liquid guiding surface 20a is inclined downwards, the essential oil will flow along the liquid guiding surface 20a under the action of gravity and be guided to an area away from the air outlet 10b and the liquid inlet tube 30, thus effectively preventing the accumulation of essential oil on the protective rim 20. This not only prevents essential oil from re-entering the airflow channel and causing secondary pollution or blockage, but also ensures the continuous and stable atomization performance of the atomizer 1, improves the utilization efficiency of the essential oil, and extends the service life of the atomizer 1.

[0042] Please see Figures 1 to 3 Furthermore, this application proposes that the main body 10 is also provided with a mist outlet channel 10c, which is connected to the outside and located above the liquid guiding surface 20a.

[0043] Specifically, the mist outlet channel 10c within the main body 10 is a structure used to guide the atomized essential oil mist from the atomization area to the external environment. This mist outlet channel 10c can be a separate pipe, a hole, or a series of interconnected chambers. Its shape can be circular, square, or other geometric shapes suitable for gas flow, ensuring that the essential oil mist can be effectively discharged from the atomizer 1 for the user to inhale or diffuse into the environment. The mist outlet channel 10c communicates with the outside world, typically through one or more mist outlets 3c. These mist outlets 3c can be located at the top, side, or bottom of the main body 10, depending on the overall structure of the atomizer 1 and the intended use.

[0044] Furthermore, the mist outlet channel 10c is positioned above the liquid guiding surface 20a, meaning that the inlet or main part of the mist outlet channel 10c is vertically higher than the liquid guiding surface 20a. For example, the liquid guiding surface 20a can be an inclined plane, and the mist generated by the atomizer 1 is discharged from the space or hole above the inclined plane.

[0045] Through the above technical solution, the mist outlet channel 10c provided on the main body 10 ensures the smooth discharge of the essential oil mist generated by atomization. More importantly, by positioning the mist outlet channel 10c above the liquid guiding surface 20a, the discharge path of the essential oil mist is effectively separated from the flow path of the returning essential oil liquid in space. During its ascent, the essential oil mist is not obstructed or contaminated by the returning essential oil liquid flowing downwards along the liquid guiding surface 20a, thus ensuring atomization efficiency and the purity of the essential oil mist. This design avoids secondary contact between the essential oil mist and the returning liquid, effectively preventing the mist from being recondensed or discharged carrying the returning liquid, thereby improving the overall performance of the atomizer 1 and the user experience.

[0046] Please see Figures 3 to 6 To address the problems of clogging of the air outlet 10b and oil outlet 30b, decreased atomization performance, and shortened equipment lifespan caused by the high viscosity and easy backflow of essential oils in traditional atomizing devices, this solution provides a highly integrated and easily replaceable atomizing assembly. This assembly includes an essential oil bottle 2 and an atomizer 1 installed at its opening. The liquid inlet channel 30a of the atomizer 1 is connected to the essential oil inside the bottle.

[0047] The core innovation of this solution lies in the precise optimization of the atomizer 1 structure and its integrated design with the essential oil bottle 2. The atomizer 1 is manufactured using high-precision injection molding, resulting in a compact size. Its main body 10 features a protective eaves 20, similar to a roof structure, around the air outlet 10b. This effectively intercepts and guides backflow of essential oil during atomization, preventing the air outlet 10b and oil outlet 30b from becoming clogged and ensuring continuous and stable atomization. Crucially, the atomizer 1 is pre-installed as a stopper at the mouth of the essential oil bottle 2 at the factory, forming a complete storage and replacement unit. Users do not need to replace the atomizer 1 separately; they only need to replace the entire essential oil bottle 2 when the essential oil is used up, simultaneously updating the atomizer 1 and fundamentally avoiding device failure caused by micropore clogging or wear of the atomizer 1.

[0048] During operation, when external compressed gas is ejected at high speed from the air outlet 10b through the air inlet channel 10a of the atomizer 1, the essential oil is drawn out from the oil outlet 30b and atomized under negative pressure. The protective rim 20 continuously prevents backflow during this process. This assembly, through its integrated, backflow-preventing, and replaceable design, systematically solves the clogging problem in essential oil atomization. It boasts significant advantages such as anti-clogging durability, ease of use (replacing the filter with the bottle), cost-effectiveness, and the ability to ensure long-term stable mist output from the aromatherapy diffuser, thereby improving the overall reliability of the product and the user experience.

[0049] Please see Figures 3 to 6 This application proposes an aroma diffuser, which includes a housing 3, a compressor pump 4, and the aforementioned atomizing assembly. The housing 3 has an inner cavity 3a, a mounting cavity 3b, and a mist outlet 3c. The mist outlet 3c communicates with the mounting cavity 3b, and the mounting cavity 3b communicates with the inner cavity 3a. The compressor pump 4 is installed in the inner cavity 3a. One end of the bottle opening of the essential oil bottle 2 of the atomizing assembly is detachably connected to the mounting cavity 3b. The air inlet channel 10a of the atomizer 1 of the atomizing assembly is connected to the compressor pump 4.

[0050] The core innovation of this embodiment lies in the fact that by combining the above-mentioned atomizing assembly with the specific cavity structure of the compressor pump 4 and the outer shell 3, the protective rim 20 set near the air outlet 10b of the atomizer body 1 can effectively block the backflow of essential oil liquid, thereby preventing liquid from adhering to the tiny openings of the air outlet 10b or the oil outlet 30b, and significantly reducing the risk of micropore blockage.

[0051] Specifically, the inner cavity 3a of the outer shell 3 is used to accommodate the compressor pump 4, the mounting cavity 3b is connected to the inner cavity 3a to realize airflow transmission, and the mist outlet 3c is connected to the mounting cavity 3b to ensure that the atomized essential oil diffuses smoothly to the outside. The essential oil bottle 2 of the above-mentioned atomizing assembly is detachably connected to the mounting cavity 3b through the bottle mouth end, so that the air intake channel 10a of the atomizer 1 is directly connected to the compressor pump 4. When the compressed gas is sprayed out from the air outlet 10b through the air intake channel 10a, it interacts with the essential oil sprayed out from the adjacent oil outlet 30b to achieve atomization.

[0052] Because the protective rim 20 is located above or to the side of the air outlet 10b, its protruding structure can physically intercept any essential oil liquid that may flow back during atomization, preventing it from adhering to the critical orifice area. Furthermore, the side of the protective rim 20 facing away from the liquid inlet pipe 30 is designed as a downwardly sloping liquid guiding surface 20a, which can guide the intercepted liquid away from the air outlet 10b and the oil outlet 30b. Based on this, the detachable connection between the mounting cavity 3b of the outer shell 3 and the bottle opening of the essential oil bottle 2 facilitates maintenance and replacement, while the direct connection between the compressor pump 4 and the air inlet channel 10a of the atomizer 1 ensures a stable airflow supply.

[0053] The above technical solution effectively solves the problem of micropore blockage caused by essential oil backflow, improves the stability of atomization effect and the service life of the equipment, and avoids the risk of whole machine failure caused by impurity deposition or device wear.

[0054] In some embodiments of this application, the aroma diffuser includes a housing 3, a compressor pump 4, and an atomizing assembly, wherein one end of the essential oil bottle 2 of the atomizing assembly is detachably connected to the mounting cavity 3b. However, in actual use, the installation and removal of the essential oil bottle 2 may not be convenient, or the stability and sealing of the connection may be difficult to guarantee, thereby affecting the user experience of the aroma diffuser and the effective atomization of the essential oil.

[0055] Please see Figures 3 to 6 In this regard, this application further proposes that the outer shell 3 includes an upper shell 31 and a lower shell 32 detachably connected to the upper shell 31. The lower shell 32 has the mounting cavity 3b on the side facing away from the upper shell 31. One end of the bottle mouth of the essential oil bottle 2 is provided with a mounting flange 32a. The mounting flange 32a is spaced apart from the bottle mouth of the essential oil bottle 2, and the outer wall of the mounting flange 32a is threadedly connected to the cavity side wall of the mounting cavity 3b.

[0056] Specifically, the outer casing 3 of the aroma diffuser is designed as a detachable upper shell 31 and lower shell 32. This structure makes the installation and replacement of the internal components, especially the essential oil bottle 2, more convenient. For example, through a simple disassembly operation, users or maintenance personnel can easily access the mounting cavity 3b, thereby simplifying the replacement process of the essential oil bottle 2 and improving the maintenance efficiency and user-friendliness of the equipment. Meanwhile, the mounting cavity 3b is located on the side of the lower shell 32 facing away from the upper shell 31. This layout optimizes the installation position of the essential oil bottle 2 to the lower part of the aroma diffuser, helping to lower the overall center of gravity of the equipment and thus enhancing the stability of the aroma diffuser during operation. This design also makes the installation of the essential oil bottle 2 more intuitive, allowing users to easily insert, remove, or screw it in from above or the side.

[0057] Furthermore, a mounting flange 32a protrudes from one end of the bottle opening of the essential oil bottle 2. This mounting flange 32a is a ring-shaped or partially ring-shaped structure extending outward from the bottle opening area of ​​the essential oil bottle 2, and its main function is to provide a structured connection interface for the essential oil bottle 2. This flange can be designed with external threads, serving as the structural basis for threaded connection with the mounting cavity 3b, thereby ensuring that the essential oil bottle 2 can be securely fixed inside the aromatherapy diffuser. The mounting flange 32a is spaced apart from the bottle opening of the essential oil bottle 2. This spacing design provides necessary space between the bottle opening of the essential oil bottle 2 and the mounting flange 32a. This space can be used to accommodate a sealing element or to provide a buffer and guiding area for the atomized essential oil mist, ensuring that the function of the essential oil bottle 2's opening is not affected and facilitating subsequent mist transmission.

[0058] Furthermore, the outer wall of the mounting flange 32a is threadedly connected to the side wall of the mounting cavity 3b. Threaded connection is an efficient and reliable mechanical fixing method. By screwing the corresponding threads on the side wall of the mounting flange 32a on the essential oil bottle 2 into the mounting cavity 3b, the essential oil bottle 2 can be quickly installed and removed. This connection method not only provides strong mechanical support, preventing the essential oil bottle 2 from accidentally loosening or falling off during use, but also forms a tight fit when tightened, helping to improve the sealing performance at the connection and effectively reducing the risk of essential oil leakage.

[0059] Through the above technical solution, the outer shell 3 of the aroma diffuser is designed as a detachable upper shell 31 and lower shell 32, with the mounting cavity 3b located on the side of the lower shell 32 facing away from the upper shell 31. This makes the installation position of the essential oil bottle 2 more reasonable and significantly improves the ease of operation. The mounting flange 32a protruding from one end of the essential oil bottle 2 is threadedly connected to the side wall of the mounting cavity 3b via its outer wall, providing a stable, reliable, and repeatedly detachable fixing method for the essential oil bottle 2. This threaded connection ensures the stability and good sealing of the essential oil bottle 2 during the operation of the aroma diffuser, effectively avoiding problems such as essential oil leakage or loose connections. This not only simplifies the replacement process of the essential oil bottle 2 and improves the user experience, but also ensures that the atomizing assembly can stably communicate with the essential oil bottle 2 and precisely align with the air intake channel 10a of the compressor pump 4, thereby ensuring efficient and continuous essential oil atomization by the aroma diffuser, improving the overall atomization effect and the reliability of the equipment operation.

[0060] Please see Figures 3 to 6 This application further proposes that in the above-mentioned aroma diffuser, a mist guiding space 3d is formed between the mounting flange 32a and the mouth of the essential oil bottle 2, and the mist guiding space 3d is connected to the mist outlet 3c; a mist passage hole is provided at one end of the mouth of the essential oil bottle 2, the mist passage hole is connected to the essential oil bottle 2, and the mist passage hole is located within the mist guiding space 3d.

[0061] Specifically, the mist-guiding space 3d formed between the mounting flange 32a and the mouth of the essential oil bottle 2 refers to a cavity region of a specific shape constructed between the mounting flange 32a and the mouth of the essential oil bottle 2. This space is designed to provide a concentrated and controlled flow path for the essential oil mist generated by the atomizer 1. For example, by precisely designing the inner wall shape of the mounting flange 32a and the outer wall shape of the mouth of the essential oil bottle 2, a closed channel, either annular or non-annular, can be formed after assembly, thereby effectively collecting and guiding the essential oil mist.

[0062] The connection between the mist-guiding space 3d and the mist outlet 3c means that there are one or more open channels between the mist-guiding space 3d and the mist outlet 3c of the aroma diffuser. These channels can be direct openings or designed short pipes to ensure that the essential oil mist collected in the mist-guiding space 3d can flow directly and smoothly to and be discharged from the outside of the aroma diffuser. This connectivity is a necessary condition for the effective discharge of essential oil mist.

[0063] One end of the mouth of the essential oil bottle 2 is provided with a mist passage hole, which is one or more openings located at the end of the mouth of the essential oil bottle 2. The mist passage hole serves as the entrance for the mist generated by the atomizer 1 to enter the mist guiding space 3d. Its size, shape, and number can be optimized according to the mist output of the atomizer 1 and the structure of the mist guiding space 3d to ensure that the mist can enter smoothly.

[0064] The mist vent is connected to the essential oil bottle 2, meaning that the mist vent forms a continuous channel with the interior of the essential oil bottle 2 (i.e., the area where the atomizer 1 produces mist). Since the atomizer 1 is usually installed at the mouth of the essential oil bottle 2, its mist outlet 3c will directly or indirectly face the space inside the mouth of the essential oil bottle 2. Therefore, the mist vent acts as a bridge between this internal space and the mist guiding space 3d, ensuring that the essential oil mist produced by the atomizer 1 can smoothly enter the mouth area of ​​the essential oil bottle 2 from the interior of the atomizer 1.

[0065] The mist vent is located within the mist guiding space 3d, meaning its opening is completely within the boundary of the space. Through precise structural design and assembly, the mist vent at the end of the essential oil bottle 2's neck is aligned with and surrounded by the entrance of the mist guiding space 3d. This ensures that the mist exiting the essential oil bottle 2's neck is effectively captured and guided by the mist guiding space 3d, preventing leakage or disorderly diffusion within the mounting cavity 3b.

[0066] Through the above technical solution, a mist-guiding space 3d is formed between the mounting flange 32a and the mouth of the essential oil bottle 2, and this mist-guiding space 3d is connected to the mist outlet 3c, providing a clear and concentrated flow path for the essential oil mist generated by the atomizer 1. The essential oil mist enters the mist-guiding space 3d directly through the mist-passing hole at the mouth of the essential oil bottle 2 and is effectively guided to the mist outlet 3c. This design avoids the disorderly diffusion, retention, or condensation of essential oil mist in the mounting cavity 3b, significantly improving the collection and discharge efficiency of essential oil mist, ensuring that the aromatherapy diffuser can stably and efficiently output essential oil mist, thereby enhancing the aromatherapy effect and user experience.

[0067] In some embodiments of the aroma diffuser described above, the essential oil bottle 2 is connected to the mounting cavity 3b of the outer casing 3 via a mounting flange 32a at its mouth, forming a mist-guiding space 3d for guiding the mist. However, during the connection process between the essential oil bottle 2 and the mounting cavity 3b, since the essential oil bottle 2 contains essential oil liquid and the compressor pump 4 provides air pressure to the atomizer 1, if the connection is not sealed tightly, essential oil leakage may occur, affecting the use environment and cleanliness of the aroma diffuser. It will also cause air pressure loss, thereby affecting the atomization effect and the overall performance of the aroma diffuser.

[0068] For this, please refer to Figures 3 to 6This application further proposes that a sealing gasket 3e is installed between the bottom wall of the mounting cavity 3b and the end of the mounting flange 32a, and the sealing gasket 3e abuts against the bottle opening of the essential oil bottle 2. The bottom wall of the mounting cavity 3b is the bottom structure of the mounting cavity 3b, typically a flat surface or a surface with a specific shape, which provides support and positioning for the installation of the essential oil bottle 2 and serves as a pressure-bearing surface for the sealing gasket 3e. The end of the mounting flange 32a refers to the distal portion of the mounting flange 32a, which is opposite to the bottom wall of the mounting cavity 3b when the essential oil bottle 2 is installed. This end, together with the bottom wall, forms a space to accommodate the sealing gasket 3e and applies pressure to the sealing gasket 3e to achieve a seal. The sealing gasket 3e is a ring-shaped or irregularly shaped component made of an elastic material, such as silicone rubber, nitrile rubber, fluororubber, or polytetrafluoroethylene, which has good resilience, oil resistance, and aging resistance. The function of the sealing gasket 3e is to provide a compressible medium between the two mating surfaces to fill minute gaps, thereby preventing leakage of fluids (such as essential oils) or gases (such as compressed air). The bottle neck of the essential oil bottle 2 is the opening portion of the essential oil bottle 2, serving as the channel for the essential oil to flow out and the atomized gas to enter. During installation, the sealing gasket 3e will directly contact the outer edge of the bottle neck or a specific sealing area to form a seal. Abutment refers to the sealing gasket 3e being compressed between the bottom wall of the mounting cavity 3b and the end of the mounting flange 32a, and making tight contact with the bottle neck of the essential oil bottle 2. This tight contact causes the sealing gasket 3e to undergo elastic deformation, thereby filling the minute gaps at the joint and forming an effective sealing barrier.

[0069] By installing a sealing gasket 3e between the bottom wall of the mounting cavity 3b and the end of the mounting flange 32a, and ensuring that the sealing gasket 3e abuts against the mouth of the essential oil bottle 2, a reliable seal can be effectively formed at the connection between the essential oil bottle 2 and the aroma diffuser housing 3. This sealing gasket 3e compensates for tolerances between the connecting parts and absorbs minor unevenness that may occur during assembly, thereby preventing essential oil from leaking from the mouth of the essential oil bottle 2 into the mounting cavity 3b or the outside of the housing 3. Simultaneously, this sealing structure also helps maintain the air pressure provided by the compressor pump 4, ensuring that air pressure does not escape from the connection gaps, thus guaranteeing that the atomizer 1 can obtain a stable airflow for efficient atomization, improving the atomization effect and overall operational stability of the aroma diffuser.

[0070] The following example will provide a more detailed explanation of the above technical solution: Please see Figures 3 to 6 In an aroma diffuser application scenario, user A wants to use the device to diffuse essential oil fragrance within a specific space. The diffuser integrates a misting assembly, which includes an essential oil bottle 2 and a misting device 1. The misting device 1 is installed at the mouth of the essential oil bottle 2, and its liquid inlet channel 30a is connected to the essential oil bottle 2 to ensure a continuous supply of essential oil.

[0071] When the aroma diffuser is started, the compressor pump 4 inside its outer casing 3 begins to operate, generating high-pressure gas. This high-pressure gas is ejected at high speed from the air outlet 10b through the air inlet channel 10a of the atomizer 1. According to Bernoulli's principle, a local negative pressure zone is formed near the air outlet 10b. Since the oil outlet 30b of the atomizer 1 is located near the air outlet 10b, the essential oil in the essential oil bottle 2 is drawn into the liquid inlet channel 30a of the atomizer 1 through the essential oil conduit and is then drawn out from the oil outlet 30b by negative pressure. The high-speed airflow shears and impacts the essential oil at the intersection of the air outlet 10b and the oil outlet 30b, breaking the essential oil into tiny atomized particles, forming an essential oil mist.

[0072] During the essential oil atomization process, due to the surface tension and viscosity of essential oils, some essential oil particles may not be completely atomized, or they may flow back or condense under the influence of airflow, forming larger droplets. If these droplets flow back directly to the air outlet 10b or the oil outlet 30b, they can easily cause micropore blockage, thus affecting the atomization effect and the lifespan of the device. To solve this problem, a protective rim 20 is provided at one end of the atomizer 1 body 10 near the air outlet 10b. This protective rim 20 is located above or to the side of the air outlet 10b, and its main function is to physically block these backflowing essential oil liquids.

[0073] Specifically, the protective awning 20 protrudes from the outer periphery of the main body 10 and the liquid inlet pipe 30, forming an effective interception area. Furthermore, the side of the protective awning 20 facing away from the liquid inlet pipe 30 is designed as a liquid guiding surface 20a. This liquid guiding surface 20a is inclined downwards from the side adjacent to the main body 10 towards the side away from the main body 10. When the returning essential oil is intercepted by the protective awning 20, it flows along the inclined liquid guiding surface 20a and is effectively guided to an area away from the air outlet 10b and the oil outlet 30b, thereby preventing the accumulation and clogging of the essential oil in the critical atomization area. Compared to the prior art where the returning essential oil directly adheres to the edge of the micropores, causing clogging, the design of the protective awning 20 and its liquid guiding surface 20a provides a proactive liquid management mechanism, significantly reducing the risk of clogging.

[0074] Meanwhile, the main body 10 of the atomizer 1 is also provided with a mist outlet channel 10c, which is connected to the outside and located above the liquid guiding surface 20a. This design ensures that the essential oil mist can be smoothly discharged through the mist outlet channel 10c after it is generated, without being affected by the backflow of essential oil liquid on the liquid guiding surface 20a, thus ensuring atomization efficiency and mist quality.

[0075] In the entire aroma diffuser, the mouth of the essential oil bottle 2 of the atomizing assembly is detachably connected to the mounting cavity 3b of the aroma diffuser housing 3. A mounting flange 32a protrudes from the mouth of the essential oil bottle 2, spaced apart from the mouth of the essential oil bottle 2. The outer wall of the mounting flange 32a is threadedly connected to the side wall of the mounting cavity 3b, achieving a secure installation and easy replacement of the essential oil bottle 2. A mist-guiding space 3d is formed between the mounting flange 32a and the mouth of the essential oil bottle 2, and this space communicates with the mist outlet 3c of the housing 3. A mist-passing hole is provided at the mouth of the essential oil bottle 2, communicating with the bottle and located within the mist-guiding space 3d. Thus, the essential oil mist generated by the atomizer 1 enters the mist-guiding space 3d through the mist-passing hole and then diffuses to the external environment through the mist outlet 3c. To ensure airtightness, a sealing gasket 3e is installed between the bottom wall of the mounting cavity 3b and the end of the mounting flange 32a. The sealing gasket 3e abuts against the mouth of the essential oil bottle 2, effectively preventing essential oil leakage and airflow loss, and further improving the overall performance and reliability of the aromatherapy diffuser.
