Description

Technical Field

[0001] This invention belongs to the field of personal care technology, and in particular relates to a nose clip-type essential oil release device with controllable release amount. Background Technology

[0002] Currently, there are many limitations to essential oil (or plant extract) devices on the market. Aroma diffusers rely on a power source and are bulky, making them impractical for portability. Essential oil (or plant extract) necklaces and bracelets release the oil through natural evaporation, which not only makes the release amount difficult to control but also results in low efficiency in getting the active ingredients into the nasal cavity. Some nasal devices have a simple structure, making the release of essential oils (or plant extracts) uncontrollable, and they cannot be controlled separately for the left and right nostrils, making them unsuitable for "unilateral discomfort" scenarios such as unilateral nasal congestion or migraines. In addition, using a single material of slow-release cotton makes it difficult to adapt to different volatile essential oils, and when using two or more essential oils at the same time, the problem of rapid consumption of volatile essential oils and insufficient release of non-volatile essential oils can easily occur.

[0003] Chinese patent document CN218010594U discloses a lemon nasal clip for nausea, comprising: a clip body and clip arms. The clip body has a through-tube structure, with breathable end caps at both ends, at least one of which is detachable. The clip arms are elastic members, located on the outer periphery of the clip body, with one end connected to one end of the clip body. In use, a lemon essential oil block is placed inside the clip body, and then the clip body is inserted into the nostril. The clip arms are positioned on the outside of the nostril, clamping the clip onto the nose. When the user breathes, air flows through the clip body into the nose. As the air passes through the clip body, it carries the aroma of the lemon essential oil block, allowing for effective absorption and thus helping to stop nausea. The two breathable end caps both limit the position of the lemon essential oil block and allow air to pass through. The through-tube structure of the clip body provides better ventilation and makes it more convenient to use.

[0004] Different types of essential oils (or plant extracts) have varying volatile and non-volatile properties due to their different compositions. In actual use, a rapid evaporation rate of essential oil in the nasal cavity can cause strong irritation and a poor user experience, while a slow evaporation rate may not provide sufficient therapeutic effects. In the aforementioned patented solution, the evaporation rate of the essential oil remains constant, making it incompatible with multiple different types of essential oils and preventing the simultaneous use of two or more types of essential oils. Summary of the Invention

[0005] To overcome the technical problems of existing essential oil release devices, which offer a wide variety of essential oils with varying release rates, and where excessively rapid release rates can cause over-stimulation of the nasal cavity, while slow release rates result in delayed therapeutic effects, this invention aims to provide a nasal clip-type essential oil release device with controllable release. This device combines two or more cotton bodies with high and low absorbency to form a slow-release cotton, adjusts the release rate of the same or more essential oils, and further adaptively fine-tunes the release by adjusting the connectivity area of ​​the mounting tube. This satisfies the differentiated release needs of essential oils and improves the user experience.

[0006] To achieve the above objectives, the present invention employs the following technical solution: a nose clip-type essential oil release device with controllable release volume, comprising two release components and a U-shaped elastic clip disposed between the two release components; each release component includes an installation tube disposed on the U-shaped elastic clip, a slow-release cotton detachably connected to the installation tube for slow-release of essential oil, and a round cap rotatably connected to the outer periphery of the installation tube; wherein, the slow-release cotton includes a low-absorbency cotton body and a high-absorbency cotton body detachably connected to the low-absorbency cotton body; the outer wall of the installation tube is provided with at least one first grid hole communicating with the interior of the installation tube; the round cap can selectively seal the first grid hole.

[0007] Optionally, the oleophilicity of the highly absorbent cotton body is greater than that of the low-absorbent cotton body.

[0008] Optionally, the highly absorbent cotton body and the low-absorbent cotton body are made of the same material; the porosity of the highly absorbent cotton body is greater than that of the low-absorbent cotton body.

[0009] Furthermore, the low-absorbency cotton body is wrapped around the periphery of the high-absorbency cotton body.

[0010] Specifically, the low-absorption cotton body is disposed on one side of the high-absorption cotton body; a separation membrane is disposed between the low-absorption cotton body and the high-absorption cotton body.

[0011] Furthermore, the outer wall of the round cap is provided with at least one second grid hole that communicates with the interior of the round cap; the communication area between the first grid hole and the second grid hole can be selectively adjusted.

[0012] Furthermore, the lower end of the round cap is provided with multiple toothed grooves; the lower end of the mounting tube is provided with elastic protrusions for hindering the movement of the toothed grooves.

[0013] Optionally, a scale mark is provided on the lower part of the outer wall of the round cap; an indicator mark is provided at the lower end of the mounting tube, which is directly opposite the scale mark.

[0014] Specifically, the scale markings include a plurality of truncated cones evenly distributed along the circumference of the cap; each truncated cone is provided with a recessed hole, and the area of ​​each recessed hole decreases sequentially along the circumference of the cap.

[0015] Furthermore, an annular groove is provided on the lower part of the outer wall of the mounting tube; at least one elastic clip is provided on the lower part of the inner wall of the round cap, which engages with the annular groove; the elastic clip is slidably connected within the annular groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. This invention uses a U-shaped elastic clip to wear two release components inside the nasal cavity, achieving portable wear and efficient inhalation.

[0018] 2. This invention uses selectable types of slow-release cotton and layered slow-release cotton to carry the same or two or more essential oils (or plant extracts), adapting to different types and release rates of essential oils (or plant extracts) to meet the diverse needs of general care and precise slow release; it can not only adjust the release rate of a single essential oil, but also enable two or more essential oils to be released synergistically, enriching the application scenarios.

[0019] 3. This invention adjusts the area of ​​the mounting tube containing the essential oil release cotton to the outside by adjusting the area of ​​the first grid hole and the second grid hole facing each other. The individual release component has an independent volume control structure and precise side-by-side volume control. In addition, the toothed groove and elastic protrusion locking structure and scale design also provide convenience for adjusting the release volume. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

They are only for the convenience of describing this invention 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. They should not be construed as limiting the specific protection scope of this invention.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature, and in the description of this invention, "a number" means two or more, unless otherwise explicitly specified.

[0030] In this invention, unless otherwise explicitly specified and limited, terms such as "set" and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0031] See Figures 1-6 A nasal clip-type essential oil release device with controllable release volume includes two release components and a U-shaped elastic clip 11 disposed between the two release components; the U-shaped elastic clip 11 has a U-shaped structure, with both ends fixedly connected to the two release components respectively, and is adapted to nasal septums of different thicknesses.

[0032] The release assembly includes an installation tube 12 disposed on the U-shaped elastic clip 11, a slow-release cotton 3 detachably connected to the installation tube 12 for slow-release of essential oil, and a round cap 21 rotatably connected to the outer periphery of the installation tube 12; the outer wall of the installation tube 12 is provided with four first grid holes 122 evenly distributed along the circumferential direction and communicating with the interior of the installation tube 12; the outer wall of the round cap 21 is provided with four second grid holes 22 evenly distributed along the circumferential direction and communicating with the interior of the round cap 21.

[0033] The lower end of the round cap 21 is provided with four evenly distributed toothed grooves 25; the lower end of the mounting tube 12 is provided with elastic protrusions 111 for hindering the movement of the toothed grooves 25; the lower part of the outer wall of the round cap 21 is provided with four scale marks 24; the lower end of the mounting tube 12 is provided with an indicator mark 112 that is selectively opposite to the four scale marks 24; the scale mark 24 is a frustum; the frustum is provided with a concave hole, and the area of ​​each concave hole decreases sequentially along the circumference of the round cap 21.

[0034] The lower part of the outer wall of the mounting tube 12 is provided with an annular groove 121; the lower part of the inner wall of the round cap 21 is provided with at least four elastic clips 23 that are evenly distributed along the circumference and engage with the annular groove 121; the elastic clips 23 are slidably connected in the annular groove 121.

[0035] The slow-release cotton 3 includes a low-absorbency cotton body 31 and a high-absorbency cotton body 32 detachably connected to the low-absorbency cotton body 31. The high-absorbency cotton body 32 has strong adsorption and can firmly lock in volatile essential oils, preventing them from evaporating prematurely. The low-absorbency cotton body 31 has weaker adsorption and is suitable for low-volatility essential oils. It will not over-lock in the essential oils (leading to non-evaporation) and can control the evaporation rate of the essential oils through weak adsorption. By using two different types of slow-release cotton with varying adsorption properties, the release efficiency and duration of volatile and non-volatile essential oils are balanced, avoiding the problem of excessively rapid consumption of volatile essential oils and insufficient release of non-volatile essential oils when using more than two types of essential oils at the same time.

[0036] The highly absorbent cotton body 32 has a higher oleophilicity than the low-absorbent cotton body 31. The highly absorbent cotton body 32 can be made of a strongly oleophilic material, such as polyester fiber; the low-absorbent cotton body 31 can be made of a moderately or mildly oleophilic material, such as viscose fiber. Alternatively, the same material can be used, but with different porosities. For example, the highly absorbent cotton body 32 can be made of high-porosity fiber, such as polyester fiber with a porosity of 65%-85%, and the low-absorbent cotton body 31 can be made of low-porosity fiber, such as polyester fiber with a porosity of 35%-60%.

[0037] Working principle:

[0038] 1. Layered sustained release: For single essential oils (or plant extracts) or multiple essential oils (or plant extracts) with consistent volatility, the sustained release cotton uses an inner and outer layer structure (such as...). Figure 5 As shown in the second embodiment 3b), the inner and outer layers are connected. The inner layer is a highly absorbent cotton body 32, and the outer layer is wrapped with a low-absorbent cotton body 31. The essential oil (or plant extract) is adsorbed by the highly absorbent cotton body 32 and slowly evaporates through the low-absorbent cotton body 31.

[0039] For essential oils (or plant extracts) with varying volatility, the slow-release cotton uses a top-bottom (or left-right) layer structure (e.g.) Figure 5 As shown in the first embodiment 3a), a separating membrane 33 is used in the middle for separation. A highly absorbent cotton body 32 is suitable for volatile essential oils to reduce loss, while a low-absorbent cotton body 31 is suitable for non-volatile essential oils to ensure release. Although it is a top-bottom (or left-right) layer structure, for volatile essential oils (or plant extracts), an inner-outer layer structure can be used on the basis of the top-bottom (left-right) layers, using the same method as above (e.g., Figure 5 (As shown in the third embodiment 3c).

[0040] 2. Release Amount Control: By rotating the round cap 21, the facing area (i.e., the connected area) of the first grid hole 122 and the second grid hole 22 is adjusted, thereby achieving release amount adjustment. For gear locking and identification, when the round cap 21 is rotated, the elastic protrusion 111 engages with the corresponding arc-shaped toothed groove 25 of the round cap 21, producing a slight clicking sensation to indicate that the target gear has been reached. After locking, it can prevent displacement due to vibration during movement or when looking down. The outer scale facilitates quick identification of the current release gear (e.g., 3 intensities: "." corresponds to weak release, "o" to medium release, and "O" to strong release).

[0041] 3. Independent unilateral dosage control: By independently rotating the two round caps 21, the release volume of the left and right nasal cavities can be adjusted differently (such as strong release on one side and weak release on the other side).

[0042] How to use:

[0043] 1. Select the appropriate type of layered slow-release cotton combination based on the type and volatility of the essential oil. (For single essential oils or essential oils with consistent volatility, an inner and outer layer structure slow-release cotton can be used, and the essential oil can be directly soaked in the cotton. For two or more essential oils with inconsistent volatility, they can be divided into highly volatile essential oils and non-volatile essential oils. A top-bottom (or left-right) layer structure slow-release cotton can be used, with highly absorbent cotton soaking in highly volatile essential oils and low-absorbent cotton soaking in non-volatile essential oils. After adding a separating membrane in the middle, it is placed into the installation tube, using a top-bottom or left-right layer structure. For highly volatile essential oils (or plant extracts), an inner and outer layer structure can also be used, as a whole with a low-absorbent cotton (soaked in non-volatile essential oils), with a separating membrane in the middle, and then placed into the installation tube to form a top-bottom or left-right layer structure.)

[0044] After inserting the slow-release cotton, close the round cap.

[0045] 2. Rotate the two round caps independently as needed to adjust the corresponding nostrils to "weak release, medium release, strong release" or "closed" (e.g., when one nostril is congested due to a cold, adjust the strong release to the congested nostril and the weak release to the unobstructed nostril).

[0046] 3. Clip the U-shaped elastic clip in the middle of the nostril so that the two release components are located in the corresponding nostril.

[0047] Beneficial effects:

[0048] 1. Portable, stable, and safe to use: The compact size and nose clip design allow for direct wear, making it suitable for various scenarios such as driving, office work, and sports. The layered slow-release cotton effectively prevents leakage by holding essential oils (or plant extracts), while the elastic protrusions and toothed locking design prevent displacement due to vibration, further enhancing the stability and safety of use.

[0049] 2. The release amount is precise and controllable. By rotating the round cap to adjust the connection area of ​​the first and second grid holes, the release amount can be precisely controlled to meet different concentration requirements and avoid waste or discomfort due to excessive concentration.

[0050] 3. The single-sided independent volume control structure is adapted to specific scenarios such as nasal congestion due to colds and migraines, achieving "precise treatment" and breaking through the limitations of traditional simultaneous volume control of both nostrils.

[0051] 4. The gear lock and intuitive scale design allow the elderly and children to quickly identify and operate the gears, solving the problems of unclear gear positions and easy misadjustment.

[0052] 5. Strong compatibility with essential oils and lower loss: The layered and detachable slow-release cotton uses different materials or combinations of materials with different porosities to adapt to volatile (such as peppermint and lemon) and non-volatile (such as sandalwood and cedar) essential oils respectively, avoiding rapid consumption or insufficient release, and improving the utilization rate and release uniformity of essential oils.

[0053] 6. High efficiency and superior user experience: The release component is located directly inside the nostril, and the active ingredients are directly inhaled after being released in layers, reducing volatilization loss and quickly exerting effects such as refreshing, soothing, and clearing the nasal passages; the overall structure is simple and easy to use, suitable for various groups of people and diverse needs, upgrading from "general care" to "precise relief".

[0054] Example 1 (Suitable for volatile essential oils: peppermint plant extract, for refreshing / nasal decongestion scenarios)

[0055] 1. U-shaped elastic clip: Made of food-grade PP material, the "U"-shaped opening is elastic and can be adapted to nasal septums of different thicknesses.

[0056] 2. Release components:

[0057] Installation tube: The surrounding structure is a fence-like structure with 1mm wide gaps and 4 gaps. There are 3 elastic protrusions on the outer edge.

[0058] Slow-release cotton: The high-absorbency cotton body is made of polyester fiber (80% porosity, solid cylinder, 2mm diameter, 8mm length), and the low-absorbency cotton body is made of polyurethane sponge (40% porosity, hollow cylinder, 4mm outer diameter, 2mm inner diameter, 8mm length). The high-absorbency cotton body can be inserted into the hollow of the low-absorbency cotton body.

[0059] Round cap: made of food-grade PP material, with 1mm wide and 4 gaps in the fence, 3 sets of arc-shaped grooves on the inner side, and engraved ".", "o" and "O" markings on the outer side. It is connected to the installation tube by a flexible clip.

[0060] When using (for unilateral nasal congestion during a cold): Soak the prepared slow-release cotton in peppermint extract and place it into the installation tube, then screw on the round cap; turn the round cap on the congested side to the "O" strong release setting (to accelerate nasal patency), and turn the unobstructed side to the "." weak release setting (to avoid irritation).

[0061] Example 2 (Suitable for non-volatile essential oils: lavender essential oil, for soothing scenarios)

[0062] 1. U-shaped elastic clip: made of silicone, lightweight and with moderate elasticity.

[0063] 2. Release components:

[0064] Installation tube: The surrounding structure is a grid-like structure with 1mm wide gaps and 4 gaps. There is a silicone elastic protrusion (1mm in diameter) on the outer edge.

[0065] Slow-release cotton: The adsorption layer (highly adsorbent cotton body) is made of polyester fiber (porosity 80%, thickness 2mm), and the controlled-release layer (lowly adsorbent cotton body) is made of polyurethane sponge (porosity 40%, thickness 4mm), with a combined diameter of 4mm.

[0066] Round cap: made of food-grade PP material, with 1mm wide gaps in the fence, 4 gaps, 4 sets of arc-shaped grooves on the inner side, and engraved ".", ".", "o", and "O" markings on the outer side. It is connected to the installation tube by a flexible clip.

[0067] When using: Soak the slow-release cotton (thin absorbent layer + thick controlled-release layer) in lavender essential oil and place it into the installation tube, then fasten the round cap; depending on your need for relaxation before bed, rotate both round caps to the "o" medium-release position (elastic protrusions engage with the corresponding grooves, creating a locking indicator); wear the U-shaped elastic clip to position the release component inside the nostril. It can be used continuously for 6-8 hours, with even release of essential oil and no risk of displacement.

[0068] Example 3 (Soothing Scenarios: Synergistic Use of Volatile and Non-Volatile Essential Oils)

[0069] Synergistic essential oil blend: volatile soothing essential oil (bergamot essential oil, which has the effect of relieving anxiety and refreshing mood) + non-volatile soothing essential oil (lavender essential oil, which has the effect of calming the nerves and promoting sleep). The two work together to achieve the dual effect of "rapid relief + long-lasting calming".

[0070] 1. U-shaped elastic clip: made of silicone, lightweight and with moderate elasticity.

[0071] 2. Release components:

[0072] Installation tube: It has 4 holes with a diameter of 1mm around the perimeter and 3 silicone elastic protrusions (diameter of 1mm) on the outer edge.

[0073] Slow-release cotton: The high-absorbency cotton body is made of polyester fiber (80% porosity, 6mm diameter cylinder, 5mm length, balancing adsorption capacity and slow release rate), used to adsorb bergamot essential oil; the low-absorbency cotton body is made of polyurethane sponge (40% porosity, 6mm diameter cylinder, 5mm length, ensuring stable release of lavender essential oil), with an interlayer separating the layers to form an upper and lower structure, with a total length of 10mm, which perfectly fits the inner diameter and height of the installation tube without loosening or shifting.

[0074] Round cap: Made of silicone, with 4 holes of 1mm diameter around the perimeter, 3 sets of arc-shaped grooves on the inner side, and "●", "●●", and "●●●" scales engraved on the outer side. The corresponding essential oil release rate is marked next to the scale. It is connected to the installation tube by a flexible clip, making it easy to disassemble.

[0075] When using:

[0076] 1. Essential oil soaking: Soak highly absorbent cotton balls in bergamot essential oil (soaking time 5 minutes to ensure full absorption), and soak low-absorbent cotton balls in lavender essential oil (soaking time 8 minutes to adapt to the non-volatile properties). After soaking, stack the two layers with a separating film in between to form an upper and lower layer structure, and put it into the installation tube.

[0077] 2. Gear adjustment: After fastening the round cap, rotate the round caps of the two release components until the elastic protrusions are engaged in the "●●" release position. At this time, the opening and closing degree of the fence gap is 60%, which is suitable for the need for a soothing and balanced release before sleep.

[0078] 3. How to wear and use: Clip the U-shaped elastic clip in the middle of the nostril, and insert the two release components into the corresponding nostrils to ensure no exposure and no discomfort; Bergamot essential oil is released through the highly absorbent cotton body temperature to relieve daytime anxiety, while lavender essential oil is continuously released through the low absorbent cotton body for long-lasting calming and soothing. The two work together to effectively improve sleep quality.

[0079] Other embodiments:

[0080] 1. Slow-release cotton material: High- and low-absorption cotton bodies can be made of the same material (such as sponge, foam, fiber, etc.), achieving different adsorption properties through different porosities. For example, the porosity can be adjusted within the range of 70%-90% (high-absorption cotton body) and 30%-50% (low-absorption cotton body). Alternatively, different materials can be used. For example, high-absorption cotton bodies can be made of high-porosity sponge, fiber felt, etc., while low-absorption cotton bodies can be made of low-porosity foam, activated carbon composite sponge, etc.

[0081] 2. Gear and scale design: Multiple gears can be set, and the scale can be replaced by numbers "1, 2, 3, 4" or text "micro, weak, medium, strong" to adapt to different users' recognition habits.

[0082] 3. Connection method between the round cap and the mounting tube: In addition to elastic clips and threads, a rotary damping structure can be used to further improve the smoothness of gear adjustment.

[0083] 4. U-shaped elastic clip material: Plastic, silicone, titanium alloy, etc. can be selected to improve wearing comfort and durability.

[0084] 5. Layered combination variants: Pre-set combination kits can be designed (such as "volatile group" and "non-volatile group"), or accessories with adsorption layers and controlled release layers of different thicknesses can be provided for easy replacement by users.

[0085] 6. The first / second grid hole can also be other shapes. The release amount can be adjusted according to the shape gap by rotating the mounting tube and the angle of the round cap.

[0086] 7. The device can be used for semi-finished products that require users to add essential oils (or plant extracts) or slow-release cotton before use, or it can be used as a finished product that has already been added with essential oils (or plant extracts).

[0087] 8. The device can be a reusable product in which the user can add essential oils (or plant extracts) or replace the slow-release cotton, or it can be a disposable product in which essential oils (or plant extracts) cannot be added or the slow-release cotton cannot be replaced.
