Description

Technical Field

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

[0002] In modern life, people often use aromatherapy in cars or indoors. By adding plant essential oils to the diffuser bottle, they allow the oil to diffuse slowly and naturally into the air, creating a fragrant environment, sterilizing and deodorizing, and refreshing the mind. Existing aromatherapy diffusers typically use essential oil bottles to hold the essential oils and use a cap with a misting device to atomize and disperse the extracted plant essential oils into the air. Examples include a floor-standing aromatherapy diffuser (application number CN202222870506.0) and an aromatherapy diffuser (application number CN202222634733.3).

[0003] In these aroma diffusers, the bottle opening and cap are threaded together. However, by using external threads on the bottle opening and internal threads on the cap, the cap fits over the bottle opening, creating a gap between the cap's inner top surface and the bottle opening's top surface. Since the essential oil, after atomization, flows out through an exhaust channel at the top of the bottle, and the inner diameter of this channel is generally much smaller than the cap's inner diameter, this sudden reduction in diameter obstructs the flow of the essential oil mist. The mist accumulates inside the cap and diffuses horizontally from its inner top surface. During this diffusion, it seeps between the inner and outer threads through the gap between the cap's inner top surface and the bottle opening's top surface, potentially causing oil residue. While existing technologies use sealing rings for further sealing, these rings are typically made of rubber or silicone, which are easily corroded and aged by essential oils, affecting their elasticity and sealing effectiveness. To ensure a tight seal, users have to tighten the essential oil bottle and cap even more, which can further reduce the elasticity of the sealing ring and wear down the thread, resulting in a further decrease in the sealing effect and even problems such as stripping, thus affecting its service life.

[0004] Therefore, it is necessary to develop an oil-resistant aromatherapy diffuser with good sealing performance and long service life. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes an oil-resistant aromatherapy diffuser with better sealing and a longer service life.

[0006] The technical solution of this utility model is implemented as follows:

[0007] An oil-resistant aromatherapy diffuser includes an essential oil container and an atomizing cover with an exhaust channel; the atomizing cover is provided with a first external thread, and the atomizing cover is threadedly connected to the essential oil container through the first external thread; furthermore, a first sealing ring is sleeved between the atomizing cover and the essential oil container, and the first sealing ring is located at the upper end of the connection between the atomizing cover and the essential oil container.

[0008] Furthermore, the atomizing cap includes a cap body, the bottom of which is provided with a threaded section, the first external thread is provided on the outer side of the threaded section, the first sealing ring is fitted on the upper end of the outer side of the threaded section, and the cap body is provided with an atomizing core and the exhaust channel.

[0009] Furthermore, the atomizing cap and / or essential oil container are provided with an annular groove, and the first sealing ring is fitted into the annular groove.

[0010] Furthermore, the atomizing core includes a pressurizing channel that is substantially parallel to the radial direction of the cover and a liquid guiding tube that is substantially parallel to the axial direction of the cover. One end of the pressurizing channel located inside the cover is connected to an air nozzle. The upper end of the liquid guiding tube is connected to or adjacent to the side of the air nozzle. In addition, a liquid outlet hole is provided on the side of the upper end of the liquid guiding tube near the air nozzle.

[0011] Furthermore, it also includes a body, the upper end of which is provided with a accommodating chamber for holding an essential oil container, and the cover is provided with a second external thread, the cover being threadedly connected to the accommodating chamber through the second external thread, and a second sealing ring is sleeved between the cover and the accommodating chamber, the second sealing ring being located at the upper end of the connection between the cover and the accommodating chamber.

[0012] Furthermore, it also includes a device head, which is provided with a third external thread. The device head is connected to the top thread of the atomizing cover via the third external thread. The device head is provided with an air collection chamber and an aromatherapy hole is opened at the top of the device head. The exhaust channel is connected to the outside through the air collection chamber and the aromatherapy hole in sequence. A third sealing ring is fitted between the device head and the atomizing cover. The third sealing ring is located at the upper end of the connection between the device head and the atomizing cover.

[0013] Furthermore, the top surface of the machine head is higher than the top surface of the machine body.

[0014] Furthermore, the outer surface of the essential oil container is provided with a first texture.

[0015] Furthermore, the outer surface of the machine head is provided with a second texture.

[0016] Furthermore, the essential oil container and atomizing cap are made of metal.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] By providing a first external thread on the atomizing cap, when the atomizing cap is threadedly connected to the essential oil container, the upper end of the essential oil container fits over the outside of the atomizing cap. There is no gap between the top surface inside the atomizing cap and the top surface of the essential oil container, thus preventing the atomized essential oil from leaking from the top surface inside the atomizing cap and reducing oil dripping. Similarly, it also prevents the atomized essential oil from horizontally diffusing from the top surface inside the atomizing cap to contact the first sealing ring. In particular, the first sealing ring is located at the upper end of the connection between the atomizing cap and the essential oil container. Even if the atomized essential oil seeps vertically into the gap between the essential oil container and the atomizing cap, the threaded structure itself has good sealing properties, so the first sealing ring is the last to come into contact with the essential oil, greatly reducing the possibility of it being corroded by the essential oil, slowing down the aging rate of the first sealing ring, and allowing the first sealing ring to maintain good elastic recovery performance and sealing effect for a longer period of time.

[0030] Reference Figures 1-6

[0031] An oil-resistant aromatherapy diffuser includes an essential oil container 100 and an atomizing cover 200 with an exhaust channel 204. The atomizing cover 200 is provided with a first external thread 1, and the atomizing cover 200 is threadedly connected to the essential oil container 100 through the first external thread 1. Furthermore, a first sealing ring 2 is sleeved between the atomizing cover 200 and the essential oil container 100, and the first sealing ring 2 is located at the upper end of the connection between the atomizing cover 200 and the essential oil container 100.

[0032] During aromatherapy, the essential oil in the essential oil container 100 is atomized. Since the atomizing cap 200 is threadedly connected to the essential oil container 100 via the first external thread 1, meaning the upper end of the essential oil container 100 fits over the outside of the atomizing cap 200, there is no gap between the top surface inside the atomizing cap 200 and the top surface of the essential oil container 100. This prevents the atomized essential oil from leaking from the top surface inside the atomizing cap 200, reducing oil dripping. Similarly, it also prevents the atomized essential oil from horizontally diffusing from the top surface inside the atomizing cap 200 to contact the first sealing ring 2. In particular, the first sealing ring 2 is located at the upper end of the connection between the atomizing cap 200 and the essential oil container 100, ensuring that even if the atomized essential oil leaks from the top surface inside the atomizing cap 200, it will not leak. The gas seeps vertically into the gap between the essential oil container 100 and the atomizing cap 200. Because the inner diameter of the atomizing cap 200 is less different from that of the essential oil container 100 at the connection point between the two, it does little to obstruct gas flow. Furthermore, the threaded structure itself has good sealing properties, and the first sealing ring 2 is the last to come into contact with the essential oil, greatly reducing the possibility of it being corroded by the essential oil. This slows down the aging rate of the first sealing ring 2, allowing it to maintain good elastic recovery performance and sealing effect for a longer period of time. It also reduces the possibility of thread wear or even stripping, thereby extending the service life of the anti-oil-drip aromatherapy diffuser.

[0033] In a preferred embodiment, the atomizing cap 200 includes a cap body 201, the bottom of which is provided with a threaded section 202. The first external thread 1 is provided on the outer side of the threaded section 202, and the first sealing ring 2 is sleeved on the upper end of the outer side of the threaded section 202. Furthermore, the cap body 201 is provided with an atomizing core 203 and an exhaust channel 204. Under the action of the atomizing core 203, the essential oil is atomized and discharged from the exhaust channel 204.

[0034] In this embodiment, the cover 201 and the threaded section 202 are integrally formed to prevent gaps between the bottom surface of the cover 201 and the top surface of the threaded section 202; furthermore, the inner surface of the threaded section 202 is smooth, effectively preventing essential oil from sticking to the inner surface of the threaded section 202; in addition, the outer diameter of the bottom surface of the cover 201 is larger than the outer diameter of the threaded section 202, which serves as a limiting effect.

[0035] In a preferred embodiment, the atomizing cover 200 is provided with an annular groove 3, and the first sealing ring 2 is fitted in the annular groove 3, which can better fix the first sealing ring 2 to the outer side of the atomizing cover 200.

[0036] In this embodiment, the annular groove 3 is located above the first external thread 1, ensuring that the first sealing ring 2 is located at the upper end of the connection between the atomizing cap 200 and the essential oil container 100.

[0037] In some alternative embodiments, the annular groove 3 may also be provided on the essential oil container 100, or two symmetrical annular grooves 3 may be provided on the atomizing cap 200 and the essential oil container 100, respectively covering both sides of the first sealing ring 2.

[0038] In a preferred embodiment, the atomizing core 203 includes a pressurizing channel 2031 that is substantially parallel to the radial direction of the cover 201 and a liquid guiding tube 2032 that is substantially parallel to the axial direction of the cover 201. One end of the pressurizing channel 2031 located inside the cover 201 is connected to an air nozzle 2033. The upper end of the liquid guiding tube 2032 is connected to or adjacent to the side of the air nozzle 2033. Furthermore, a liquid outlet hole 2034 is provided on the side of the upper end of the liquid guiding tube 2032 near the air nozzle 2033.

[0039] In this embodiment, the upper end of the liquid guide tube 2032 is fixedly connected to the side of the air nozzle 2033. In some optional embodiments, the upper end of the liquid guide tube 2032 can be fixedly connected to the port of the pressurization channel 2031, the cover 201, or the essential oil container 100, as long as the liquid outlet 2034 is close to the air nozzle 2033 and the high-pressure airflow ejected from the air nozzle 2033 can impact the essential oil ejected from the liquid outlet 2034.

[0040] In this embodiment, both the liquid outlet 2034 and the air nozzle 2033 are located at the upper end of the threaded section 202. The mist formed by the impact of the high-pressure airflow from the air nozzle 2033 on the essential oil sprayed from the liquid outlet 2034 mainly diffuses at the upper end of the threaded section 202. This design, on the one hand, shortens the distance between the atomized essential oil and the exhaust channel 204, allowing the essential oil mist to be discharged better and faster. On the other hand, it also reduces the possibility of the atomized essential oil seeping into the gap between the essential oil container 100 and the atomizing cap 200.

[0041] The principle and structure of atomizing liquid by impacting it with high-pressure airflow is existing technology and has been disclosed in patent documents such as an essential oil atomizing core (application number CN201821575853.8), an aroma diffuser (application number CN202222918650.7), an aroma diffuser that can hold multiple essential oils at the same time (application number CN201922369990.7), and a multi-variety essential oil atomizing aroma diffuser (application number CN201821069616.4), and will not be repeated here.

[0042] In a preferred embodiment, the device further includes a body 300, the upper end of which is provided with a receiving compartment 301 for accommodating the essential oil container 100. The cover 201 has a second external thread 4, which connects the cover 201 to the receiving compartment 301. A second sealing ring 5 is fitted between the cover 201 and the receiving compartment 301, located at the upper end of the connection between the cover 201 and the receiving compartment 301. The body 300 provides support for the essential oil container 100, allowing it to be fixed at the user's desired height, and also provides sufficient space for the installation of devices such as air pumps and controllers.

[0043] In this embodiment, the design of the second external thread 4 and the second sealing ring 5 can fix the relative positions of the atomizing cap 200 and the essential oil container 100 on the body 300, while also reducing the possibility that the atomized essential oil will leak into the container 301 and then further leak into the outside through the gap between the cap 201 and the container 301. At the same time, the second sealing ring 5 is located at the upper end of the connection between the cap 201 and the container 301, which also reduces the possibility that the second sealing ring 5 will be corroded by the essential oil.

[0044] In some optional embodiments, the accommodating chamber 301 is fitted with the essential oil container 100 and the cover 201 to form an airflow space. One end of the pressurizing channel 2031 is connected to the airflow space. Furthermore, an air pump is installed inside the body 300, and the air outlet of the air pump is connected to the airflow space, so that the high-pressure gas generated by the air pump is sequentially injected into the essential oil container 100 through the airflow space, the pressurizing channel 2031, and the air nozzle 2033.

[0045] In a preferred embodiment, the device further includes a head 400, which is provided with a third external thread 6. The head 400 is threadedly connected to the top of the atomizing cover 200 via the third external thread 6. The head 400 is provided with an air collecting chamber 401 and an aromatherapy hole 402 is opened at the top of the head 400. The exhaust channel 204 is connected to the outside through the air collecting chamber 401 and the aromatherapy hole 402 in sequence. A third sealing ring 7 is sleeved between the head 400 and the atomizing cover 200. The third sealing ring 7 is located at the upper end of the connection between the head 400 and the atomizing cover 200.

[0046] In this embodiment, the lower end of the gas collecting chamber 401 is open, and there are multiple exhaust channels 204. The upper end of each exhaust channel 204 is surrounded inside the lower end of the head 400. The essential oil mist in the essential oil container 100 can enter the gas collecting chamber 401 through multiple exhaust channels 204 and finally flow out to the outside through the aromatherapy hole 402. The cross-sectional area of ​​the essential oil container 100, the total cross-sectional area of ​​the multiple exhaust channels 204, and the cross-sectional area of ​​the aromatherapy hole 402 decrease sequentially. Compared with the design of directly discharging to the outside through a single exhaust channel 204, the above design can effectively reduce the abruptness of the change in the channel area of ​​the essential oil mist flowing out to the outside, making the process of the essential oil mist being discharged to the outside more gradual.

[0047] In addition, a third external thread 6 is provided on the head 400 and a third sealing ring 7 is provided at the upper end of the connection between the head 400 and the atomizing cover 200. This design also reduces the leakage and oil dripping of the atomized essential oil, and also reduces the possibility of the third sealing ring 7 being corroded by the essential oil, thereby improving the sealing effect and effectively ensuring that the atomized essential oil is discharged from the aromatherapy hole 402 instead of leaking from the gap between the head 400 and the atomizing cover 200.

[0048] In a preferred embodiment, the top surface of the head 400 is higher than the top surface of the body 300, making it easier to grip and rotate.

[0049] In a preferred embodiment, the outer surface of the essential oil container 100 is provided with a first texture 101, which is a CD texture, mainly used to enhance friction and has the effects of anti-slip and anti-fingerprint.

[0050] In a preferred embodiment, the outer surface of the head 400 is provided with a second texture 403, which is a diamond-shaped texture and is mainly used to enhance friction and prevent slippage.

[0051] As a preferred embodiment, the essential oil container 100 and the atomizing cap 200 are made of metal, which has good corrosion resistance and wear resistance, and also avoids the problems of plastic consumables falling off and clogging, as well as discoloration, that exist when using plastic materials.

[0052] Working principle:

[0053] In use, essential oil is poured into the essential oil container 100, and then the atomizing cap 200 is placed on top of the essential oil container 100 and screwed to the essential oil container 100 through the first external thread 1. At the same time, the motor head 400 is screwed onto the atomizing cap 200 through the third external thread 6. Then, the essential oil container 100 is placed into the receiving cavity and screwed to the receiving chamber 301 through the second external thread 4, so that the essential oil container 100, the atomizing cap 200 and the motor head 400 are all fixed on the body 300. Finally, the high-pressure airflow is sprayed into the essential oil container 100 through the pressurization channel 2031 and the nozzle 2033 and impacts the essential oil sprayed from the liquid outlet 2034, causing the essential oil to atomize. The atomized airflow will be discharged to the outside through the exhaust channel 204, the air collection chamber 401 and the aromatherapy hole 402, realizing the aromatherapy function.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
