Description

[0001] This application is a divisional application. The application number of the original application is 202111586653.9, the application date is December 23, 2021, and the name of the invention is "An aromatherapy method and aromatherapy device based on powdered essential oil." Technical Field

[0002] The invention belongs to the technical field of aromatherapy, and in particular relates to an aromatherapy method and an aromatherapy device based on powdered essential oil. Background Art

[0003] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not necessarily be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0004] The current aromatherapy methods are roughly as follows: Liquid essential oil ultrasonic atomization: This method applies ultrasonic vibrations to liquid essential oils, or mixtures of liquid essential oils and water, to stimulate the liquid essential oils (or mixtures of liquid essential oils and water) into molecular or molecular clusters, which are then released into the surrounding air to create aromatherapy. A typical example is the current mainstream aromatherapy device, the ultrasonic aromatherapy atomizer. High-speed airflow disperses liquid essential oils: High-speed airflow passes through the liquid film or droplets of essential oils, dispersing the liquid essential oils into molecules or molecular clusters, which are then released into the surrounding air to complete the aromatherapy process. Typical products include pump-type diffusers. Airflow diffusion: Airflow passes through liquid essential oil or solid essential oil impregnation, carrying the essential oil molecules into the surrounding air to complete the aromatherapy. A typical product is a wet curtain aromatherapy humidifier. Thermal evaporation: Heat the liquid or solid essential oil impregnation, causing the essential oil to evaporate into gas and enter the surrounding air to complete the aromatherapy. Typical products include electronic cigarettes; Combustion: Ignite the impregnated material with essential oils, allowing the essential oil molecules to enter the surrounding air to complete the aromatherapy. Typical products include scented candles, burning incense, etc. Natural evaporation: Liquid essential oils, their solutions, or solid essential oil impregnations are placed in the air, where the essential oil molecules naturally diffuse into the surrounding air, completing the aromatherapy process. Typical products include scented cakes.

[0005] In the aromatherapy industry, in addition to traditional natural evaporation and combustion products, the current mainstream products are liquid essential oil ultrasonic atomization and high-speed airflow blowing liquid essential oil, both of which use liquid essential oil as the fragrance source and consumables.

[0006] Because most essential oils are corrosive and volatile, the storage and transportation of all liquid essential oils imposes specific requirements on container material, sealing, temperature, and pressure. During use, essential oils, due to their high viscosity, strong adhesion, and corrosive properties, can form a layer of oil on equipment and container exteriors, a process known as "oil creep." This can coat equipment and containers, negatively impacting the user experience and making them difficult to clean.

[0007] Mixing different types of liquid essential oils will most likely cause chemical reactions, changing the smell and quality. This is bound to happen when changing essential oils in the same aromatherapy device.

[0008] This is an inevitable drawback of using liquid essential oils for aromatherapy, which is difficult to solve. This situation has also affected the development of compound aromatherapy, making compound aromatherapy remain at the conceptual stage and difficult to promote among the general public. Summary of the Invention

[0034] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0035] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] See also Figure 1 This embodiment provides an aromatherapy method based on powdered essential oil, comprising the following steps: Metering: Metering the powdered essential oil to quantitatively take out the essential oil for use; Release: Physically manipulate the essential oil to break the microcapsules that encapsulate the essential oil and release the essential oil. Diffusion: Dilute the essential oil released from the microcapsules with air to diffuse it within a certain space; The metering, releasing and diffusion steps are controlled in a coordinated manner according to the aroma concentration requirements and performed in one of the following modes: M1: metering, release, and diffusion steps are performed continuously; M2: metering, release, and diffusion steps are performed synchronously and intermittently; M3: The metering step is performed intermittently, while the release and diffusion steps are performed continuously; M4: The metering and release steps are performed synchronously and intermittently, and the diffusion step is performed continuously; M5: The metering and release steps are performed asynchronously and intermittently, while the diffusion step is performed continuously; M6: The metering, release, and diffusion steps are performed asynchronously and intermittently.

[0037] The metering step can be one of the following modes: Metering mode 1: Repeatedly use one or more quantitative metering containers to dispense the powdered essential oil from the storage container into the working container according to the specified amount. For example, use a spoon-type quantitative metering container to dispense the powdered essential oil from the storage container into the working container. The measuring unit is spoon.

[0038] Metering Mode 2: One or more channels are opened between the storage container and the working container, allowing the powdered essential oil to flow from the storage container into the working container along the channels. By controlling the opening time of the channels between the two containers, the powdered essential oil can be quantitatively distributed to the working container. For example, a controllable valve can be provided between the storage container and the working container. When the valve is open, the powdered essential oil can fall into the working container through the valve. The amount of powdered essential oil entering the working container can be controlled by controlling the opening time of the valve.

[0039] Metering mode 3: A metering device with a screw and / or gear set structure is set between the storage container and the working container. The powdered essential oil is transported from the storage container to the working container through the rotation of the metering device. By controlling the rotation stroke of the metering device, the purpose of quantitatively placing the powdered essential oil into the working container is achieved. For example, a controllable gear device is set between the storage container and the working container. When the gear rotates, the powdered essential oil can be brought from the storage container into the working container through the gear gap. By controlling the rotation angle or number of cycles of the gear, the amount of powdered essential oil entering the working container can be controlled.

[0040] Metering mode 4: Powdered essential oil is attached to a carrier and metered indirectly by metering the carrier. For example, the powdered essential oil is attached to a carrier such as fabric, paper, non-woven fabric, or porous minerals by molecular adsorption or adhesion. The amount of essential oil used can be controlled by quantitatively intercepting or locally administering the carrier containing the powdered essential oil.

[0041] Since the aromatherapy method provided in this embodiment uses powdered essential oil, under normal conditions, the essential oil components are wrapped in microcapsules. Therefore, when using powdered essential oil for aromatherapy, it is first necessary to destroy the stability of the essential oil capsules to release the essential oil therein.

[0042] The release step disclosed in this application can be one of the following modes: Release mode 1: Use mechanical extrusion, grinding and other devices to mechanically squeeze and grind the powdered essential oil particles in the working container to break the microcapsules of the powdered essential oil and release the essential oil therein; Release mode 2: Use a high-frequency impact device to apply high-frequency impact to the powdered essential oil particles in the working container, breaking the microcapsules of the powdered essential oil and releasing the essential oil therein; Release mode 3: Liquid solvent is supplied to the powdered essential oil in the working container, so that the microcapsules of the powdered essential oil dissolve in the solvent, thereby releasing the essential oil; Release mode 4: A heating and / or lighting device is installed on the working container to heat and / or illuminate the powdered essential oil in the working container, causing the microcapsules of the powdered essential oil to enter an unstable state, thereby achieving the purpose of releasing the essential oil therein.

[0043] The ultimate goal of aromatherapy is to evenly disperse essential oil molecules or molecular clusters into the surrounding air. After the above two steps (metering + release), the essential oil has been quantitatively released from the working container. Therefore, the next diffusion step is required to disperse the essential oil released from the microcapsules into the surrounding air as evenly as possible. The diffusion step disclosed in this application can be one of the following modes: Diffusion mode 1: The airflow flows through the working container, carrying the essential oil molecules or essential oil molecular clusters released from the microcapsules into the surrounding air, thereby achieving the purpose of diffusing the essential oil molecules into the air.

[0044] Diffusion mode 2: An ultrasonic vibration device is installed on the working container to ultrasonically atomize the liquid essential oil mixture formed in release mode 3, and an air flow is provided to the atomized essential oil mixture, carrying the misted essential oil mixture into the surrounding air, thereby achieving the purpose of diffusing the essential oil molecules or essential oil molecular clusters into the air.

[0045] Diffusion mode 3: A heating device is installed on the working container to heat the essential oil released after the release step 4, so that the essential oil evaporates into the surrounding air, thereby achieving the purpose of diffusing the essential oil molecules or molecular clusters into the air.

[0046] According to the aromatherapy concentration requirements, the above-mentioned metering, releasing and diffusion steps are carried out synchronously and continuously to obtain a continuous aromatherapy effect, and the essential oil molecules or molecular clusters are continuously and evenly distributed into the surrounding air.

[0047] In certain application requirements, such as in public places where the presence or absence of crowds is uncertain, the above-mentioned metering, releasing, and diffusion steps can be performed synchronously and intermittently according to the presence or absence of crowds or other aromatherapy targets, so as to achieve the purpose of accurately delivering essential oils and saving usage.

[0048] The intermittent method can also control the duty cycle to control the amount of essential oil used and thus the aroma concentration. For example, one or both of the metering and release steps can be intermittently performed, or one or both of the release and diffusion steps can be intermittently performed.

[0049] The above solution is used to realize the aromatherapy of a single essential oil, that is, single essential oil aromatherapy. The following further technical solution can realize the simultaneous use of multiple essential oils, that is, compound aromatherapy: In an aromatherapy time and space, the quantitative placement of multiple powdered essential oils is completed separately or centrally by the metering step, so that multiple essential oils participate in the aromatherapy in the same time and space according to the specified ratio, and the release step is implemented separately or centrally, and the diffusion step is carried out centrally to achieve compound aromatherapy.

[0050] The so-called aromatherapy in the same time and space refers to the aromatherapy action carried out in the aromatherapy space of the same aromatherapy device at the same time, which is different from the following situations: the aromatherapy of different types of essential oils is carried out by the same aromatherapy device at different times (for example, the same aromatherapy device first emits lavender essential oil for 3 seconds, and then emits lemon essential oil for 10 seconds); in the same space, multiple aromatherapy devices simultaneously and separately emit different types of essential oils.

[0051] In the above compound aromatherapy scheme, the metering and release process of different essential oils can be: 1) Separate measurement and release; 2) Separate metering and centralized release; 3) Centralized metering and release.

[0052] The purpose of performing the processes separately is to avoid mixing of the different essential oil forms, which could cause chemical reactions and deteriorate the aromatherapy. The purpose of performing the processes centrally is to simplify the aromatherapy equipment and reduce costs. This can also prevent mixing of the different essential oil forms, given the greater stability of powdered essential oils and / or the smaller amounts of essential oil used. Therefore, both centralized and separate processes are within the scope of protection of this application.

[0053] In the above embodiment, since powdered essential oil is used, its advantage is that it can avoid the defects of liquid essential oil in storage, transportation and use. Moreover, since powdered essential oil does not have the easy leakage, strong fluidity and strong corrosiveness of liquid essential oil, the requirements for the metering device are relatively simple, which can reduce the design difficulty and cost.

[0054] See also Figure 2 and Figure 3 A single aromatherapy device based on powdered essential oil includes a device body 1 and a control circuit. The device body 1 includes an essential oil storage container (not shown), a metering device 13, a release device 15 and a diffusion device 16. The essential oil storage container, the metering device 13, the release device 15 and the diffusion device 16 are connected in sequence. The control circuit is electrically connected to the metering device 13, the release device 15 and the diffusion device 16. The essential oil storage container is used to store powdered essential oil. The metering device 13 is used to quantitatively distribute the powdered essential oil from the essential oil storage container. The release device 15 is used to crush and / or melt and / or destabilize the microcapsules to release the essential oil in the microcapsules. The diffusion device 16 is used to spread the released essential oil into the surrounding air in the form of molecules or molecular clusters.

[0055] See also Figure 2 In one embodiment, the metering device 13 includes a housing 1 and a metering rotor 131 disposed within the housing 1. The housing 1 is connected to the essential oil storage container via a feeding port 12. The metering rotor 131 is rotatably connected to a bearing (not shown) on the inner wall of the housing 1 via a metering shaft 132. The circumferential side wall of the metering rotor 131 is provided with at least one metering recess 133. The metering rotor 131 is driven to rotate by a metering driver (not shown).

[0056] See also Figure 2 In one embodiment, the shell 1 is connected to the essential oil storage container via a docking port 11 , and a spiral 111 is provided on the inner wall of the docking port 11 to achieve a threaded connection between the shell 1 and the essential oil storage container.

[0057] In another embodiment, the metering and placement of the microcapsules may be achieved by using a screw-type, gear-type, valve-type, peristaltic-type mechanism, etc., which is not limited here.

[0058] See also Figure 2 In one embodiment, the release device 15 includes a second shell and a roller 151 arranged inside the second shell. The roller 151 is eccentrically installed inside the second shell through a release shaft 152. The diameter of the roller 151 is smaller than the inner cavity diameter of the second shell. During the eccentric rotation of the roller 151 inside the second shell, its circumferential side wall can fit with the inner wall of the second shell, and a gap 153 is formed between the roller 151 and the inner wall of the second shell for powdered essential oil to flow into. The second shell and the first shell are connected through the metering outlet 14.

[0059] In another embodiment, the release of the powdered essential oil can be achieved by extrusion, high-frequency impact, solvent dissolution, heating, illumination, stirring, etc., which are not limited here.

[0060] See also Figure 2 In one embodiment, the diffusion device 16 includes a shell three and a diffusion driver (not shown) arranged inside the shell three. A diffusion chamber 161 is provided in the shell three. The shell three is connected to the shell two through a diffusion port 18. The diffusion driver is used to transport airflow into the diffusion chamber 161 to entrain the essential oil molecules from the inside of the shell two. After the powdered essential oil releases the essential oil in the shell two, the essential oil molecules or molecular clusters enter the diffusion chamber 161 through the diffusion port 18, are entrained by the airflow transported into the diffusion chamber 161 by the diffusion driver, and diffuse into the surrounding air through the diffusion outlet (not shown).

[0061] In one embodiment, the diffusion driver is an air supply device, an ultrasonic atomization device, a heating device, etc., which is not limited here.

[0062] See also Figure 2 In one embodiment, a residue collection tank 17 is further provided on one side of the second shell, and a waste outlet interface 154 is provided on the side wall of the second shell, and a waste collection interface 172 is provided on the side wall of the residue collection tank 17 to match the waste outlet interface 154. By docking the waste outlet interface 154 with the waste collection interface 172, after the powdered essential oil in the second shell undergoes the release step, the remaining residue enters the residue collection tank 17 through the waste outlet interface 154 and the waste collection interface 172, the waste outlet channel 155 inside the waste outlet interface 154, and the waste collection channel 173 inside the waste collection interface 172. The residue collection tank 17 can be removed from one side of the second shell, and after cleaning the residue therein, it can be re-docked to the second shell to continue working.

[0063] During operation, an essential oil storage container (not shown) containing powdered essential oil is docked to the essential oil storage container docking port 11. Under the influence of gravity, the powdered essential oil in the container flows through the feed port 12 into the upper end of the metering device 13. As the metering device driver (not shown) rotates the metering rotor 131, each metering notch 133 on the metering rotor 131 carries a volume of powdered essential oil corresponding to its volume to the metering discharge port 14. This powdered essential oil, under its own gravity, flows through the metering discharge port 14 into the release device 15. When the metering rotor 131 stops rotating, the powdered essential oil stops feeding into the release device 15. This process completes the metering of the powdered essential oil, with the metering unit corresponding to the volume of the metering notch 133.

[0064] After the powdered essential oil enters the gap 153 of the release device 15, it moves downward by its own gravity. Figure 2 In the process, the eccentrically mounted roller 151 rotates counterclockwise, driving the powdered essential oil from the left side of the gap 153 to the right side. At the bottom of the release device 15, the gap between the roller 151 and the inner cavity of the release device 15 is minimal, squeezing the powdered essential oil and releasing the essential oil encapsulated in the microcapsules. This process completes the release of the essential oil.

[0065] The released essential oil molecules or molecular clusters enter diffusion chamber 161 within diffusion channel 16 through gap 153. A diffusion driver (not shown) acts as an air supply device, directing airflow into diffusion chamber 161. This airflow carries the essential oil molecules or molecular clusters and diffuses them into the surrounding air through a diffusion outlet (not shown). This process completes the essential oil diffusion.

[0066] After the essential oil release step, the microcapsules encapsulating the essential oil are broken. After the essential oil is released, the microcapsule shells serve as residue and accumulate in the residue collection tank 17. The residue collection tank 17 is connected to the release device 15 via a detachable docking port. The user can remove the residue collection tank 17 for cleaning at any time when changing the type of essential oil or when the residue collection tank 17 is full of residue.

[0067] Furthermore, the release device 15 is a non-electric release device, and its operation is not controlled by the control circuit. The non-electric release device includes but is not limited to: a rotary squeezing device with a manual operating handle, a press-type squeezing device, etc. When working, the user shakes or presses the handle to complete a stage of essential oil release.

[0068] Furthermore, instead of designing a measuring device, the user scoops the powdered essential oil with a spoon-shaped measuring container and pours it into the inlet of the release device 15 to complete the essential oil metering.

[0069] Figure 3 Shows the principle block diagram of a single aromatherapy device. Figure 2 、 Figure 3 In the embodiment, the metering device 13, the release device 15 and the diffusion device 16 are all controlled by the control circuit through their respective corresponding driving mechanisms. The amount of essential oil is controlled by the operation of the metering device 13, the release speed of the essential oil is controlled by the operation of the release device 15, and thus the aroma concentration is controlled. The essential oil is fed into the diffusion device 16 through the diffusion mechanism. Furthermore, a single aromatherapy device based on powdered essential oil also includes a power supply and an interactive device. The control circuit is electrically connected to the interactive device to interact with other electronic devices to achieve remote control, interaction, etc.

[0070] The interactive device is a device that accepts operator operations, conveys the operator's intentions to the control circuit, and feeds back the operating status of the control circuit to the operator through audio-visual devices. It is electrically connected to the control circuit and includes but is not limited to buttons, touch sensors, touch screens, switches, LED indicators, display screens, buzzers / speakers, etc.

[0071] In another embodiment, a compound aromatherapy device based on powdered essential oils is provided. Different from the above-mentioned single-ingredient aromatherapy device, multiple essential oil storage containers are provided for storing different essential oils, multiple metering devices 13 are provided for respectively metering and placing different essential oils, and at least one essential oil release device 15, diffusion device 16, and residue collection device 17 are provided.

[0072] In the above embodiments, the powdered essential oil is sampled, measured, crushed, and diffused to complete the aromatherapy.

[0073] In another form of powder aromatherapy, the powdered essential oil can also be attached to a carrier (such as fabric, paper products, sponge, etc.), and the powdered essential oil can be measured by quantitatively adding the carrier; by kneading, squeezing and other operations on the carrier, the powdered essential oil capsules attached to the carrier are broken to release the essential oil; by restricting the airflow to flow through the carrier that has been kneaded, squeezed, etc., the airflow carries the released essential oil molecules or molecular clusters and disseminates them into the surrounding air to achieve diffusion.

[0078] The extrusion frame 25 is axially connected to the housing (not shown) through the extrusion frame shaft 251.

[0079] The extrusion frame 25 and the extrusion mortar 254 are installed closely together, and the carrier 20 of the powdered essential oil passes through the gap between the two. When the extrusion frame 25 drives the extrusion roller 253 installed thereon to move, the extrusion roller 253 cooperates with the extrusion mortar 254 to squeeze the carrier 20 of the powdered essential oil, which can break the powdered essential oil capsules attached thereto.

[0080] During operation, the drive device (not shown) of the carrier recovery reel 213 and / or the supply reel 211 drives the recovery reel 213 to rotate, which will take up a section of the carrier 20 and allow the new section of the carrier 20 to enter the cavity of the extrusion mortar 254. This process realizes the metering of the powdered essential oil.

[0081] The drive device (not shown) of the extrusion frame 25 drives the extrusion frame 25 to rotate, thereby driving the extrusion roller 253 mounted on the extrusion frame 25 to move, so that the extrusion roller 253 moves along the inner cavity of the extrusion mortar 254. The extrusion roller 253 rotates about its axis 252, squeezing the carrier 20 located between the extrusion roller 253 and the extrusion mortar 254, thereby breaking the microcapsules of the powdered essential oil attached to the carrier 20. This process releases the powdered essential oil.

[0082] The air supply device 26 is an axial flow fan in this embodiment. When it is in operation, it sends air into the inner cavity of the extrusion mortar 254 through the multiple air holes 255 on the extrusion mortar 254, passes through the gaps in the carrier 20, and carries the released essential oil molecules or molecular clusters to be emitted outward. This process realizes the diffusion of the powdered essential oil.

[0083] In this embodiment, as a further solution, compound aromatherapy can be achieved by changing the way the carrier 20 is attached with powdered essential oil. For details, please refer to Figure 5 The carrier 20 is divided into several parallel zones, wherein 201 is an attachment zone for a powdered essential oil; 202 is an isolation zone where no essential oil is attached; and 203 is an attachment zone for another powdered essential oil.

[0084] The density of the powdered essential oil attached to the carrier 20 (the amount of essential oil attached per unit area) and the area ratio of each zone determine the proportion of essential oil attached to the carrier 20, i.e., the ratio, and thus the formula of the compound aromatherapy.

[0085] During operation, after the same section of the carrier 20 is rolled for a certain period, two powdered essential oils determined by the attachment ratio simultaneously enter the inner cavity of the extrusion mortar 254. After being squeezed, they are simultaneously released and diffused according to the formula ratio to achieve compound aromatherapy.

[0086] Figure 5 Only the combination of two essential oils is illustrated. Compound combinations of more essential oils can be processed according to this idea and are all within the scope of protection of this application.

[0087] The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of this patent.
