Description

Technical Field

[0001] The invention relates to aromatherapy essential oil, in particular to functional aromatherapy essential oil and a preparation device thereof, and belongs to the technical field of aromatherapy. Background Art

[0002] Essential oils are widely used in aromatherapy. Traditional aromatherapy oils are often made from a single plant essential oil and have limited functionality, primarily used for scent enhancement or simple mood relief. They struggle to achieve multi-dimensional regulation of neurotransmitters, meridian systems, and biorhythms. While single lavender essential oil can act on GABA receptors through linalyl acetate, it cannot simultaneously regulate qi and blood circulation in the meridians or synchronize the body's circadian rhythm, resulting in limited sleep-inducing effects. Existing technologies lack complex formulas that can simultaneously regulate neurotransmitter transmission, stimulate meridian circulation, and regulate biorhythms, failing to meet modern needs for comprehensive mental and physical health. Traditional extraction methods have low extraction efficiency for active ingredients and can easily degrade heat-sensitive ingredients, such as ligustilide in Chuanxiong, affecting the oil's efficacy. Effective encapsulation and protection methods are lacking for easily oxidized ingredients, such as evening primrose seed oil, resulting in poor stability and difficulty in long-term storage. Furthermore, existing aromatherapy essential oil preparation devices often suffer from inaccurate feed control and low mixing efficiency. Traditional stirring devices mostly use a single motor to drive the stirring paddle, which cannot achieve time-sharing and quantitative addition of multi-component raw materials, and easily causes uneven mixing of ingredients or insufficient reaction time. At the same time, mechanical stirring may introduce metal impurities, affecting the purity of essential oils. Therefore, a functional aromatherapy essential oil and a preparation device thereof are proposed. Summary of the Invention

A magnetic stirring mechanism is provided at the bottom of the stirring tank body 11; through the cooperation of the layered drive block and the slide rod 28, the mechanical structure is used to realize the sequential control of the feed linkage flap valve 29, which can accurately realize the time-sharing and quantitative addition of multi-component raw materials. The magnetic stirring mechanism adopts non-contact magnetic drive to eliminate metal impurities that may be introduced by mechanical stirring, ensure the purity of the essential oil, and improve the mixing efficiency.

[0037] In one embodiment, the limiting mechanism includes a disc 30 fixedly mounted on the rotating shaft 20 and a limiting groove 33 opened on the base 10. A pressure sensor 35 is installed on the inner bottom wall of the limiting groove 33. The bottom of the disc 30 is fixedly connected to a sleeve 31 and a spring 32. The spring 32 is arranged inside the sleeve 31, and one end of the spring 32 is fixedly connected to a rod body 34; the pressure sensor 35 monitors the axial displacement of the rotating shaft 20 in real time, and can accurately feedback the operating status of the rotating shaft 20. The control panel 202 is triggered by the pressure change to adjust the shutdown of the first motor 21, and the feeding of the first feed hopper 14, the second feed hopper 15 and the third feed hopper 16 is controlled to ensure the accuracy of the feeding timing.

[0039] In one embodiment, a control panel 202 is provided on the base 10 and is electrically connected to the first motor 21, the second motor 41, and the pressure sensor 35. A cover 17 is threadedly connected to the top of the stirring tank 11, and a liquid outlet pipe 18 is connected to the bottom sidewall of the stirring tank 11. The control panel 202 integrates an automated control system that can precisely control the start and stop, speed, and operating timing of the first motor 21 and the second motor 41 according to a preset program.

The threaded cover 17 facilitates equipment cleaning and raw material loading, and the bottom liquid outlet pipe 18 is designed to facilitate the discharge of essential oils.

[0040] In one embodiment, the first drive block 22, the second drive block 23, and the third drive block 24 are respectively provided with a first notch portion 221, a second notch portion 231, a third notch portion 241 and a slope portion 201. The circumferential lengths of the first notch portion 221, the second notch portion 231, and the third notch portion 241 increase successively along the rotating shaft 20 and are adapted to the inclination angle of the slope portion 201. The first drive block 22, the second drive block 23, and the third drive block 24 slide into the first notch portion 221, the second notch portion 231, and the third notch portion 241 successively through the sliding rod 28 to drive the feed linkage flap valve 29 to flip, so as to realize the time-sharing feeding control of the first feed hopper 14, the second feed hopper 15, and the third feed hopper 16. The torsion spring 26 in the fixing seat 25 provides a torsional reset force. When the slide rod 28 slides into the first notch portion 221 of the first driving block 22, the torsion spring 26 drives the connecting rod 27 to drive the slide rod 28 to return to its position, so that the feed linkage flap valve 29 flips open; through the incremental design of the circumferential length of the notch portion and the adaptation of the inclination angle of the slope portion 201, the opening timing and opening duration of each feed hopper can be accurately controlled to realize the sequential feeding of the neurotransmitter regulation group → meridian stimulation group → biorhythm regulation group, which meets the optimal mixing process requirements of each component in the formula; the reset force of the torsion spring 26 ensures that the feed linkage flap valve 29 automatically opens after the slide rod 28 slides into the notch portion in turn.

[0041] Example 1, a balanced conditioning formula, comprising 10 parts of lavender essential oil and 6 parts of Roman chamomile essential oil for the neurotransmitter regulation group, 5 parts of supercritical CO2 extract of Chuanxiong and 8 parts of cold-pressed bergamot oil for the meridian stimulation group, and 7 parts of tuberose absolute oil and 3 parts of evening primrose seed oil for the biorhythm regulation group; The neurotransmitter regulation group, the meridian stimulation group and the biorhythm regulation group are respectively loaded into the first feed hopper 14, the second feed hopper 15 and the third feed hopper 16, and the first motor 21 and the second motor 41 are started through the control panel 202. The time-sharing feeding is realized by utilizing the difference in the circumferential length of the notch portion of the driving block. The first motor 21 rotates to drive the slide rod 28 to slide into the first notch portion 221 of the first driving block 22, thereby driving the feeding linkage flap valve 29 at the first driving block 22 to flip open, and the essential oil in the first feed hopper 14 flows into the stirring tank body 11 for stirring by the magnetic stirring mechanism. The pressure sensor 35 detects the pressure change and controls the first motor 21 to stop through the control panel 202. After setting 8 minutes, the first motor 21 is turned on. The above operation is repeated. After setting 10 minutes, the first motor 21 is turned on, and the second motor 41 is set to drive the magnetic stirring assembly to mix for 30 minutes. Finally, the essential oil is collected through the liquid outlet pipe 18; 50 trial subjects were selected to verify the balanced conditioning aromatherapy essential oil of Example 1. After continuous use for one month, 88% of the trial subjects said that their overall physical and mental state improved, 8% of the trial subjects felt slightly relieved, and 4% of the trial subjects had no obvious feeling. The ingredient ratio of this example is balanced, the cost of Chuanxiong and tuberose absolute oil is moderate, and the comprehensive conditioning effect is significant.

[0042] Example 2, a soothing and sleep-inducing formula, comprising 15 parts of lavender essential oil and 10 parts of Roman chamomile essential oil for the neurotransmitter regulation group, 2 parts of supercritical CO2 extract of Chuanxiong and 5 parts of cold-pressed bergamot oil for the meridian stimulation group, and 4 parts of tuberose absolute oil and 1 part of evening primrose seed oil for the biorhythm regulation group; The neurotransmitter regulation group, meridian stimulation group and biorhythm regulation group are respectively loaded into the first feed hopper 14, the second feed hopper 15 and the third feed hopper 16, and the first motor 21 and the second motor 41 are started through the control panel 202. The time-sharing feeding is realized by utilizing the difference in the circumferential length of the notch part of the driving block. The first motor 21 rotates to drive the slide rod 28 to slide into the first notch part 221 of the first driving block 22, thereby driving the feeding linkage flap valve 29 at the first driving block 22 to flip open, and the essential oil in the first feed hopper 14 flows into the stirring tank body 11 for stirring through the magnetic stirring mechanism. The pressure sensor 35 detects the pressure change and controls the first motor 21 to stop through the control panel 202. The first motor 21 is turned on after setting 13 minutes. The above operation is repeated. The first motor 21 is turned on after setting 5 minutes, and the second motor 41 is set to drive the magnetic stirring assembly to mix for 40 minutes. Finally, the essential oil is collected through the liquid outlet pipe 18.

[0043] 50 trial subjects were selected to test the soothing and sleep-inducing aromatherapy essential oil of Example 2. After continuous use for one month, 82% of the trial subjects reported that they fell asleep faster, 13% of the trial subjects felt that their sleep depth improved, and 5% of the trial subjects did not notice any changes. In this example, the lavender essential oil has a high proportion and a sufficient content of linalyl acetate, and the sleep-inducing effect is outstanding, but the raw material cost is relatively high.

[0044] Example 3, a meridian dredging formula, comprising 8 parts of lavender essential oil and 12 parts of Roman chamomile essential oil for the neurotransmitter regulation group, 5 parts of supercritical CO2 extract of Chuanxiong and 3 parts of cold-pressed bergamot oil for the meridian stimulation group, and 10 parts of tuberose absolute oil and 5 parts of evening primrose seed oil for the biorhythm regulation group; The neurotransmitter regulation group, meridian stimulation group and biorhythm regulation group are respectively loaded into the first feed hopper 14, the second feed hopper 15 and the third feed hopper 16, and the first motor 21 and the second motor 41 are started through the control panel 202. The time-sharing feeding is realized by utilizing the difference in the circumferential length of the notch part of the driving block. The first motor 21 rotates to drive the slide rod 28 to slide into the first notch part 221 of the first driving block 22, thereby driving the feeding linkage flap valve 29 at the first driving block 22 to flip open, and the essential oil in the first feed hopper 14 flows into the stirring tank body 11 for stirring through the magnetic stirring mechanism. The pressure sensor 35 detects the pressure change and controls the first motor 21 to stop through the control panel 202. The first motor 21 is turned on after setting 12 minutes. The above operation is repeated. After setting 14 minutes, the first motor 21 is turned on, and the second motor 41 is set to drive the magnetic stirring assembly to mix for 45 minutes. Finally, the essential oil is collected through the liquid outlet pipe 18.

[0045] 50 trial subjects were recruited to experience the meridian-dredging aromatherapy essential oil of Example 3. After continuous use for one month, 82% of the trial subjects reported that their muscle tension was relieved, 15% of the trial subjects felt that their meridians were relaxed, and 3% of the trial subjects had no obvious improvement. In this example, the proportion of evening primrose seed oil and cold-pressed bergamot oil was increased, and the β-cyclodextrin encapsulation technology increased the process cost, but the meridian conditioning was highly targeted.

[0046] Comparative Example 1: A certain brand of balancing and conditioning aromatherapy essential oil on the market is simply compounded with rose essential oil and lavender essential oil, supplemented with base oil. The aroma layer is single, only focusing on emotional relief, and lacks the dimension of comprehensive physical and mental conditioning. 30 trial subjects were selected, whose age and physical and mental conditions were matched with those of the trial subjects of Example 1. A double-blind test was conducted on Example 1 and the comparative product simultaneously. After continuous use for 1 month, 87% of the trial subjects believed that Example 1 had a better balancing effect in the dual dimensions of emotional relief and physical relaxation, 8% felt that there was little difference between the two, and 5% believed that the aroma of the comparative product was more pleasing but the conditioning depth was insufficient.

[0047] Conclusion: Commercially available balancing and conditioning aromatherapy generally has the problems of single ingredient compounding and limited conditioning dimensions. Example 1 of the present invention innovatively compounds Chuanxiong oil and tuberose absolute oil, retains the active ingredients through supercritical CO2 extraction, and achieves emotional and physical balance with precise proportions. It has controllable costs and more comprehensive effects.

[0048] Comparative Example 2: A certain brand of meridian-dredging aromatherapy essential oil is commercially available. It is mainly composed of peppermint essential oil and rosemary essential oil, and is combined with ordinary base oil. It relies on a cooling sensation to temporarily relieve muscle tension, has no targeted meridian conditioning ingredients, and the essential oil evaporates quickly and has a short duration of action. 30 trial subjects were recruited, and their muscle conditions and meridian sensitivity were basically the same as those of the trial subjects in Example 3. A double-blind test was conducted to compare Example 3 with the comparative product. After continuous use for one month, 82% of the trial subjects reported that Example 3 was superior in relieving muscle tension and lasting longer in meridian relaxation, 10% believed that the two products had similar immediate cooling sensations, and 8% felt that the comparative product had a stronger fragrance.

[0049] Conclusion: Traditional meridian dredging aromatherapy relies on a single cooling ingredient, which has the problem of short-term effect. Example 3 of the present invention specifically compounds evening primrose seed oil to nourish the meridians and cold-pressed bergamot oil to promote qi and dredge the meridians, and combines β-cyclodextrin encapsulation technology to extend the duration of the essential oil effect. Although the process cost increases, it achieves deep penetration and long-term meridian conditioning, solving the pain point of traditional products with short-term relief and long-term ineffectiveness.
