Description

Technical Field

[0001] 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

[0002] The current aromatherapy methods are roughly as follows:

[0003] Liquid essential oil ultrasonic atomization: ultrasonic vibration is applied to liquid essential oil or liquid essential oil water mixture to stimulate the liquid essential oil (or liquid essential oil water mixture) into molecular or molecular cluster form, which is then released into the surrounding air to complete aromatherapy. Typical products are the current mainstream aromatherapy devices - ultrasonic aromatherapy atomizers;

[0004] High-speed airflow disperses liquid essential oil: high-speed airflow flows through the liquid film or droplets of essential oil, disperses the liquid essential oil, forms molecules or molecular clusters of liquid essential oil, and emits them into the surrounding air to complete aromatherapy. Typical products are pump-type diffusers;

[0005] Airflow entrainment diffusion: The airflow flows through liquid essential oil or solid essential oil impregnation, carrying the essential oil molecules into the surrounding air to complete the aromatherapy. The typical product is the wet curtain aromatherapy humidifier;

[0006] Thermal evaporation: Heat the liquid or solid essential oil impregnated material, so that the essential oil evaporates into gas and enters the surrounding air to complete the aromatherapy.

[0007] Typical products are e-cigarettes;

[0008] Combustion: Ignite the impregnation of essential oils to allow the essential oil molecules to enter the surrounding air to complete the aromatherapy. Typical products include scented candles, burning incense, etc.

[0009] Natural evaporation: Liquid essential oil or its solution or solid essential oil impregnation is placed in the air, and the essential oil molecules therein naturally diffuse into the surrounding air to complete the aromatherapy. Typical products are scented cakes, etc.

[0010] In the aromatherapy industry, in addition to traditional natural volatilization 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.

[0011] Since most types of essential oils are corrosive and volatile, the storage and transportation of all liquid essential oils have certain requirements for container materials, sealing, temperature, pressure, etc. During the use of essential oils, due to their high viscosity, strong adhesion and certain corrosiveness, essential oils will form a layer of essential oil on the equipment, container outer wall and other areas, commonly known as "oil creeping", which will cover the equipment and containers with a layer of essential oil, affecting the experience and making it difficult to clean.

[0012] When different types of liquid essential oils are mixed, there is a high probability that chemical reactions will occur, causing changes in smell and quality. This is bound to happen when changing essential oils in the same aromatherapy device.

[0013] This is an inevitable drawback when using liquid essential oils for aromatherapy, which is difficult to solve. This situation has further affected the development of compound aromatherapy, making compound aromatherapy remain in the conceptual stage and difficult to promote among the general public. Summary of the invention

[0068] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0069] The embodiments of the present invention are described in detail below, and examples of the embodiments 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 cannot be understood as limiting the present invention.

[0070] See also Figure 1 This embodiment provides an aromatherapy method based on powdered essential oil, comprising the following steps:

[0071] Metering: Metering the powdered essential oil to quantitatively take out the essential oil for use;

[0072] Release: Physically manipulate the essential oils to break the microcapsules that encapsulate the essential oils and release the essential oils;

[0073] Diffusion: Dilute the essential oil released from the microcapsules with air to diffuse it within a certain space;

[0074] The metering, releasing and diffusion steps are collaboratively controlled to be performed in one of the following modes depending on the aromatherapy concentration requirement:

[0075] M1: metering, release, and diffusion steps are performed continuously;

[0076] M2: The metering, release, and diffusion steps are performed synchronously and intermittently;

[0077] M3: The metering step is performed intermittently, while the release and diffusion steps are performed continuously;

[0078] M4: The metering and release steps are carried out synchronously and intermittently, and the diffusion step is carried out continuously;

[0079] M5: The metering and release steps are performed asynchronously and intermittently, and the diffusion step is performed continuously;

[0080] M6: The metering, release and diffusion steps are performed asynchronously and intermittently.

[0081] The metering step can be one of the following modes:

[0082] 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.

[0083] Metering mode 2: one or more channels are opened between the storage container and the working container, so that the powdered essential oil enters the working container from the storage 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 is set 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.

[0084] 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 by the rotation of the metering device. The purpose of quantitatively distributing the powdered essential oil to the working container is achieved by controlling the rotation stroke of the metering device. 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.

[0085] Metering mode 4: attaching the powdered essential oil to a carrier, and indirectly completing the metering of the powdered essential oil by metering the carrier, such as attaching the powdered essential oil to a carrier such as fabric, paper, non-woven fabric, porous minerals, etc. by molecular adsorption, adhesion, etc., quantitatively intercepting or locally applying the carrier carrying the powdered essential oil, so as to control the dosage of the essential oil.

[0086] 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.

[0087] The release step disclosed in this application can be one of the following modes:

[0088] 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;

[0089] Release mode 2: Use a high-frequency impact device to apply high-frequency impact to the powdered essential oil particles in the working container to break the microcapsules of the powdered essential oil and release the essential oil therein;

[0090] Release mode 3: providing a liquid solvent to the powdered essential oil in the working container so that the microcapsules of the powdered essential oil are dissolved in the solvent, thereby achieving the purpose of releasing the essential oil therein;

[0091] 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, so that the microcapsules of the powdered essential oil enter an unstable state, thereby achieving the purpose of releasing the essential oil therein.

[0092] The ultimate goal of aromatherapy is to evenly disperse the essential oil molecules or molecular clusters into the surrounding air. After the above two steps (metering + release), the essential oil has been quantitatively released in 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:

[0093] 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, so as to diffuse the essential oil molecules into the air.

[0094] 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 to carry the misted essential oil mixture into the surrounding air, so as to diffuse the essential oil molecules or essential oil molecule clusters into the air.

[0095] 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.

[0096] According to the aromatherapy concentration requirement, the above-mentioned metering, releasing and diffusing steps are performed synchronously and continuously to obtain a continuous aromatherapy effect, and the essential oil molecules or molecular clusters are continuously and evenly distributed to the surrounding air.

[0097] In some application requirements, such as in public places where the presence or absence of people is uncertain, the above-mentioned metering, releasing, and diffusing steps can be performed synchronously and intermittently according to the presence or absence of people or other aromatherapy targets, so as to achieve the purpose of accurately delivering essential oils and saving usage.

[0098] The intermittent method can also control the duty cycle to control the dosage of essential oil and thus the aromatherapy concentration. For example, one or both of the metering and releasing steps can be intermittently performed, and one or both of the releasing and diffusing steps can be intermittently performed.

[0099] The above scheme is used to realize the aromatherapy of a single essential oil, that is, single aromatherapy. The following further technical scheme can realize the simultaneous use of multiple essential oils, that is, compound aromatherapy:

[0100] In an aromatherapy space and time, the quantitative placement of multiple powdered essential oils is completed separately or collectively by the metering step, so that multiple essential oils can participate in the aromatherapy in the same space and time according to the specified ratio, and the release step is implemented separately or collectively, and the diffusion step is carried out collectively to achieve compound aromatherapy.

[0101] 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.

[0102] In the above compound aromatherapy scheme, the metering and release process of different essential oils can be:

[0103] 1) Separate measurement and release;

[0104] 2) Separate measurement and centralized release;

[0105] 3) Centralized metering and centralized release.

[0106] The process is carried out separately to avoid mixing of essential oils in different forms, causing chemical reactions and making the aromatherapy worse; while the process is carried out in a centralized manner to simplify the aromatherapy equipment and reduce costs. Under the conditions that the powdered essential oil is more stable and / or the amount of essential oil used is small, mixing of essential oils in different forms can also be avoided. Therefore, both centralized and separate processes are within the scope of protection of this application.

[0107] 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.

[0108] See also Figure 2 and Figure 3 A single aromatherapy device based on powdered essential oil comprises a device body 1 and a control circuit, wherein the device body 1 comprises an essential oil storage container (not shown), a metering device 13, a releasing device 15 and a diffusion device 16, wherein the essential oil storage container, the metering device 13, the releasing device 15 and the diffusion device 16 are connected in sequence, and the control circuit is electrically connected to the metering device 13, the releasing device 15 and the diffusion device 16, wherein the essential oil storage container is used to store the powdered essential oil, the metering device 13 is used to quantitatively distribute the powdered essential oil from the essential oil storage container, the releasing device 15 is used to crush and / or melt and / or destabilize the microcapsules to release the essential oil in the microcapsules, and the diffusion device 16 is used to spread the released essential oil into the surrounding air in the form of molecules or molecular clusters.

[0109] See also Figure 2 In one embodiment, the metering device 13 includes a shell 1 and a metering rotor 131 arranged inside the shell 1. The shell 1 is connected to the essential oil storage container through a feeding port 12. The metering rotor 131 is rotatably connected to a bearing (not shown) on the inner wall of the shell 1 through 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).

[0110] 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.

[0111] In another embodiment, the metering and placement of the microcapsules can be achieved by using a screw type, a gear type, a valve type, a peristaltic type or other type of mechanism, which is not limited here.

[0112] See also Figure 2 In one embodiment, the release device 15 includes a shell 2 and a roller 151 arranged inside the shell 2. The roller 151 is eccentrically installed inside the shell 2 through a release shaft 152. The diameter of the roller 151 is smaller than the inner cavity diameter of the shell 2. During the eccentric rotation of the roller 151 inside the shell 2, its circumferential side wall can fit with the inner wall of the shell 2, and a gap 153 is formed between the roller 151 and the inner wall of the shell 2 for powdered essential oil to flow in. The shell 2 and the shell 1 are connected through a metering outlet 14.

[0113] 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.

[0114] 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 inside 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 to the diffusion chamber 161 to entrain the essential oil molecules from 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 a diffusion outlet (not shown).

[0115] In one embodiment, the diffusion driver is an air supply device, an ultrasonic atomization device, a heating device, etc., which is not limited here.

[0116] See also Figure 2 In one embodiment, a residue collection tank 17 is further provided on one side of the second shell, a waste outlet interface 154 is provided on the side wall of the second shell, and a waste collection interface 172 matching the waste outlet interface 154 is provided on the side wall of the residue collection tank 17. By docking the waste outlet interface 154 with the waste collection interface 172, after the powdered essential oil in the second shell is released, 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 on the inner side of the waste outlet interface 154, and the waste collection channel 173 on the inner side of the waste collection interface 172. The residue collection tank 17 can be disassembled 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.

[0117] During operation, an essential oil storage container (not shown) containing powdered essential oil is docked to the essential oil storage container docking port 11, and the powdered essential oil therein enters the upper end of the metering device 13 along the feeding port 12 under the action of its own gravity. When the metering device driver (not shown) drives the metering rotor 131 to rotate, each metering notch 133 on the metering rotor 131 will carry the powdered essential oil equivalent to its volume to the metering outlet 14, and these powdered essential oils enter the release device 15 along the metering outlet 14 under their own gravity; 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, and the metering unit is equivalent to the volume of the metering notch 133.

[0118] After the powdered essential oil enters the gap 153 of the release device 15, it moves downward by its own gravity. Figure 2 When the eccentrically mounted roller 151 rotates counterclockwise, the powdered essential oil is driven to move from the left side to the right side of the gap 153. At the bottom of the release device 15, the gap between the roller 151 and the inner cavity of the release device 15 is the smallest, the powdered essential oil is squeezed, and the essential oil wrapped in the microcapsule is released. This process completes the release of the essential oil.

[0119] The released essential oil molecules or molecular clusters enter the diffusion cavity 161 in the diffusion channel 16 from the gap 153. The diffusion driver (not shown) is an air supply device that sends the airflow into the diffusion cavity 161 in a directional manner, and the essential oil molecules or molecular clusters are diffused into the surrounding air through the diffusion outlet (not shown). This process completes the diffusion of the essential oil.

[0120] After the release step of the essential oil, the microcapsules encapsulating the essential oil are broken, and after the essential oil is released, the shells of the microcapsules are accumulated as residues and enter the residue collection tank 17. The residue collection tank 17 is connected to the release device 15 through a detachable docking port, and the user can remove the residue collection tank 17 at any time for cleaning when changing the type of essential oil or when the residue in the residue collection tank 17 is full of residues.

[0121] 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 pressing squeezing device, etc. When working, the user shakes or presses the handle to complete a stage of essential oil release.

[0122] 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.

[0123] Figure 3 The schematic diagram of the single aromatherapy device is shown in FIG. Figure 2 , Figure 3In the embodiment, the metering device 13, the releasing device 15 and the diffusion device 16 are all cooperatively controlled by the control circuit through their respective corresponding driving mechanisms, and the dosage of the 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 releasing device 15 to control the aromatherapy concentration, and the essential oil is delivered to the diffusion device 16 through the diffusion mechanism. Further, 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.

[0124] The interactive device is a device that accepts operator operations, conveys the operator's intentions to the control circuit, and feeds back the working status of the control circuit to the operator through an audio-visual device. It is electrically connected to the control circuit and includes but is not limited to buttons, touch sensors, touch screens, switches, LED indicator lights, display screens, buzzers / speakers, etc.

[0125] In another embodiment, a compound aromatherapy device based on powdered essential oils is provided. Different from the above-mentioned single 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.

[0126] In the above embodiments, the sampled powdered essential oil is metered, crushed, and diffused to complete the aromatherapy.

[0127] In another form of powder aromatherapy, the powdered essential oil can also be attached to a carrier (such as fabric, paper product, sponge, etc.), and the powdered essential oil can be measured by quantitatively adding the carrier; the powdered essential oil capsules attached to the carrier can be broken by rubbing, squeezing, etc., to release the essential oil; and the airflow can be constrained to flow through the carrier that has been rubbed, squeezed, etc., so that the airflow can carry the released essential oil molecules or molecular clusters and emit them into the surrounding air to achieve diffusion.

[0128] Figure 4 , Figure 5 The structure of using powdered essential oil for aromatherapy is illustrated, wherein the aromatherapy device 2 includes a carrier supply roll 211, a carrier recovery roll 213, a carrier 20, an extrusion frame 25, at least one extrusion roller 253 axially mounted on the extrusion frame, an extrusion mortar 254 matched with the extrusion frame, a plurality of ventilation holes 255 distributed on the extrusion mortar 254, an air supply device mounting frame 257 integrated with the extrusion mortar, an air supply device 26, and necessary housings (not shown), drive devices (not shown), control circuits (not shown), etc.

[0129] Please refer to Figure 4The carrier 20 of the powdered essential oil is wound on a carrier supply roll 211 and is axially connected to a housing (not shown) via a supply roll 212 .

[0130] The carrier recovery reel 213 recovers the essential oil carrier 20 after use and is axially connected to the housing (not shown) through the supply reel 214.

[0131] At least one squeezing roller 253 is located at the periphery of the squeezing frame 25 and is axially connected to the squeezing frame 25 via a squeezing roller shaft 252 .

[0132] The extrusion frame 25 is axially connected to the housing (not shown) via an extrusion frame shaft 251.

[0133] 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 extrude the carrier 20 of the powdered essential oil, and the capsule of the powdered essential oil attached thereto can be broken.

[0134] During operation, the driving 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 a 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.

[0135] The driving device (not shown) of the extrusion frame 25 drives the extrusion frame 25 to rotate, thereby driving the extrusion roller 253 installed on the extrusion frame 25 to move, so that the extrusion roller 253 moves along the inner cavity of the extrusion mortar 254, and the extrusion roller 253 rotates around its axis 252 to squeeze 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 realizes the release of the powdered essential oil.

[0136] The air supply device 26 is an axial flow fan in this embodiment. When it is working, it sends air flow 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 emit outward. This process realizes the diffusion of powdered essential oil.

[0137] 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. Figure 5 The carrier 20 is divided into several areas in parallel, wherein 201 is an attachment area for a powdered essential oil; 202 is an isolation area where no essential oil is attached; and 203 is an attachment area for another powdered essential oil.

[0138] The attachment density of the powdered essential oil on the carrier 20 (the amount of essential oil attached per unit area) and the area ratio of each region determine the proportion of the essential oil attached to the carrier 20, that is, the ratio, thereby determining the formula of the compound aromatherapy.

[0139] During operation, after the same section of the carrier 20 is rolled for a section, two powdered essential oils determined by the attachment ratio simultaneously enter the inner cavity of the extrusion mortar 254, and after being squeezed, they are simultaneously released and diffused according to the formula ratio to achieve compound aromatherapy.

[0140] Figure 5 Only the combination of two essential oils is illustrated, and more compound combinations of essential oils can be processed according to this idea, all of which are within the protection scope of this application.

[0141] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
