Description

Technical Field

[0001] This invention relates to a fragrance aerosol generation system, and more particularly to the field of aerosol generation technology in the fragrance industry. Background Technology

[0002] China has a long history of spices, with ancient customs involving the collection of herbs to ward off disease and uncleanliness. Since the Han Dynasty, foreign spices have been introduced to China, and the use of solid spices has gradually become popular, becoming an everyday item for home health and aesthetic cultivation. Today, solid spices are widely used in homes, hotels, clubs, tea gardens, academies, meditation centers, and Taoist temples. Correspondingly, the methods of appreciating and using incense are mainly divided into burning, baking, and natural volatilization. These three methods release the aromatic components of spices, forming visible smoke or odorous fragrances, i.e., aerosols.

[0003] Incense burning refers to the direct ignition of incense with an open flame, such as the simplest stick incense, coil incense, and cone incense, which are lit with an open flame and allowed to burn quietly, releasing smoke. Incense powder, on the other hand, is typically produced by first imprinting a beautiful design of the powder onto the surface of incense ash using an incense seal, and then igniting a portion of it. Incense roasting refers to heating incense with charcoal or an electric incense burner without open flame combustion. For example, incense blocks are usually roasted by burying glowing red charcoal blocks in incense ash as a heat source, placing the blocks on mica sheets on the ash surface; incense balls are typically roasted in an incense burner heated by a resistance wire. Natural evaporation of incense generally does not require heating; instead, incense pastes are placed in open containers or incense blocks are placed in sachets, allowing them to naturally evaporate and release their aroma into the air.

[0004] The methods described above, such as direct ignition, charcoal fire, or electric furnace baking, have certain drawbacks. Open flame burning poses a risk of burns and even fires, and the incense-tasting equipment is inconvenient to carry; once ignited, it continues to burn until the incense is exhausted, resulting in waste; the process produces a lot of smoke, with a very strong aroma that cannot be regulated; and it generates large amounts of waste gases such as carbon monoxide and carbon dioxide, polluting the environment and harming human health, while the ash disposal is also troublesome. Charcoal baking is cumbersome, and the temperature cannot be controlled. Resistance heating has drawbacks such as the incense being exhausted all at once, uneven smoke evaporation, significant heat loss, limited high-temperature performance, and the inconvenience and unsightly appearance of the charging cable. Natural evaporation is only suitable for the release of a few incense components, with a slow evaporation rate, making it unsuitable for incense requiring rapid high-temperature release, thus limiting its application. These shortcomings restrict the large-scale application of natural solid incense, a precious traditional Chinese treasure, in daily life.

[0005] Taking mugwort as an example, mugwort is a plant belonging to the genus Artemisia in the Asteraceae family, and the plant has a strong aroma. In the field of Traditional Chinese Medicine, mugwort is mostly used for moxibustion. Moxibustion treatment methods can be roughly divided into contact methods (suppurative moxibustion, warm needle moxibustion, moxibustion devices, and poultices) and non-contact methods (suspended moxibustion, fumigation moxibustion, etc.). Contact methods may directly harm the human skin, while non-contact methods, which mostly use combustion, are more skin-friendly. Existing non-contact moxibustion technologies all rely on the smoke and heat generated by burning moxa sticks to fumigate and heal users; although the burning method is at a certain distance from the skin, it is still easy to burn the skin, and the residual ash from combustion can easily cause unnecessary risks such as burns and fires. Preliminary conclusions of some scientific studies indicate that excessive combustion of moxa sticks may produce hydrocarbon carcinogens. Therefore, proposing an application scheme that avoids open flame combustion while achieving the efficacy of non-contact moxibustion is of great market significance and value. Some existing technologies use resistance heaters to bake moxa products, such as the moxibustion device disclosed in patent CN210044470U, which heats the moxa cake through a recessed heating groove. However, only a small portion of the heat generated in this peripheral bottom or circumferential heating structure is conducted to one surface of the moxa cake, while most is dissipated into the supporting structure. To avoid damage to the supporting structure and adjacent electronic components, such as circuit board assemblies and batteries, the average temperature of this heating groove is controlled at a low level. Therefore, this resistive peripheral heating method is ineffective, especially for high-density materials like moxa products, often resulting in the outer surface being scorched while the inner layer remains insufficiently baked.

[0006] Taking agarwood as an example, agarwood is a mixture of resin and wood from plants of the Aquilaria genus. Its main components include sesquiterpenes, phenylethyl chromones, triterpenoids, aromatic compounds, and fatty acids. Agarwood possesses a distinctive aroma due to these components and can be extracted and processed into solid fragrances. Air-dried agarwood can also be used as a traditional Chinese medicine, believed to have therapeutic effects on the heart and nervous system. A common use of agarwood is through open-flame burning, releasing a rich aroma that can be used to enhance the atmosphere or for therapeutic purposes—a well-known application. However, similar to the application of mugwort products, achieving efficient release of its aroma without open-flame combustion remains a challenge in the research field.

[0007] It is evident that open flame combustion is a common problem in the heating process of solid fragrances. Therefore, it is urgent to develop an application solution for solid fragrances that can heat efficiently without combustion. Summary of the Invention

[0008] The present invention provides a fragrance aerosol generation system, including an electromagnetic heater and a sensing fragrance, wherein the electromagnetic heater bakes the sensing fragrance in a mode of electromagnetic induction heating without combustion, thereby controllably releasing the desired aerosol.

[0009] The technical solution of the present invention is that the fragrance aerosol generation system includes the electromagnetic heater and the induction fragrance. The electromagnetic heater includes a coil, an electromagnetic shield, a control unit, a support component and an operation panel. The coil and the control unit are electrically connected to form an electromagnetic coupling circuit. The electromagnetic shield is located near the coil to isolate electromagnetic interference. The coil, the support component and the operation panel are combined to form a fragrance chamber.

[0010] The sensing fragrance includes a fragrance matrix for generating aerosols and a receptor for generating heat and temperature marking, wherein the fragrance matrix is ​​in close physical contact with the receptor;

[0011] Specifically, when the sensor is configured as a single material, its initial permeability exhibits peak characteristics with increasing temperature in the range from room temperature (20°C) to Curie temperature; when the sensor is configured as a composite structure including a temperature-marking material, the initial permeability of the temperature-marking material exhibits peak characteristics with increasing temperature in the range from room temperature (20°C) to Curie temperature; both the single material and the temperature-marking material have a Curie temperature not exceeding 400°C.

[0012] Furthermore, the receptor is embedded inside the fragrance matrix or arranged around the periphery of the fragrance matrix, and the shape of the fragrance sensor is one of spherical, columnar, sheet-like, or disc-shaped.

[0013] Furthermore, the fragrance matrix comprises agarwood, sandalwood, musk, ambergris, frankincense, sandalwood, borneol, rosemary, cyperus, safflower, clove, fennel, cardamom, cinnamon, cyperus rhizome, rue, citronella, benzoin, tonka bean, styrax, honeysuckle, wisteria, fragrant grass, patchouli, costus root, scrophularia, ginseng, chuanxiong rhizome, atractylodes rhizome, angelica root, codonopsis root, amber, angelica dahurica, calamus, fragrant grass, mosquito repellent grass, peppermint, camphor, pine needles, eucalyptus leaves, cypress leaves, bamboo leaves, turmeric, and more. It is made from one or more of the following: mugwort, licorice, dried tangerine peel, lemon, olive, perilla leaves, tea, red dates, fruits or their kernels, flower buds of various flowers or their extracted floral water, wine or dealdehyde alcohol, honey, rock sugar, petroleum jelly, paraffin wax, musk, saltpeter, calcium carbonate, stone powder, cinnamon powder, wood powder, and other Chinese medicinal herbs and herbs that can be used in fragrances. It is prepared by one or more of the following processes: grinding, fermentation, stir-frying, steaming, drying, mixing, crushing, pressing, and kneading.

[0014] Furthermore, the coil is configured as a planar disc or a three-dimensional helical tube.

[0015] Furthermore, the control unit is provided with a control circuit capable of generating the desired electromagnetic excitation. The control circuit includes a power supply, a first resonant inductor, a second resonant inductor, a first resonant capacitor, a second resonant capacitor, and a resonant charging control switch. One end of the second resonant inductor is connected to the power supply, the other end of the second resonant inductor is connected to the first resonant capacitor, one end of the second resonant capacitor is connected to one end of the first resonant inductor, the other end of the second resonant capacitor is connected to ground, the other end of the first resonant inductor is connected to the other end of the first resonant capacitor and connected to the drain of the resonant charging control switch, and the source of the resonant charging control switch is connected to ground.

[0016] Furthermore, the electromagnetic heater also includes a heat insulation layer and a perforated cover plate. The heat insulation layer is located near or around the coil, and the perforated cover plate covers the spice compartment.

[0017] Furthermore, the peak characteristic includes a single-peak characteristic curve, wherein the operating temperature of the sensor is set to the right of the peak and close to the peak.

[0018] Furthermore, the peak characteristics include a bimodal characteristic curve, wherein the operating temperature of the sensor is set to the right of and near the first peak, or set to the right of and near the second peak.

[0019] Furthermore, the electromagnetic heater includes one or more spice chambers capable of electromagnetic induction heating, with the number of spice chambers not exceeding six.

[0020] Furthermore, the electromagnetic heater employs either a centralized overall heating method or a distributed sequential heating method for induction fragrances placed in multiple fragrance chambers.

[0021] This invention proposes a fragrance aerosol generation system, comprising an electromagnetic heater and an induction fragrance. The induction fragrance is placed in the fragrance chamber of the electromagnetic heater and heated to release aerosols. The heating mode is electromagnetic induction heating without open flame combustion. The induction fragrance includes a fragrance matrix for generating aerosols and a sensor for heating and temperature marking. The fragrance matrix and the sensor are tightly physically bonded. After receiving electromagnetic excitation from the electromagnetic heater, the sensor generates controllable eddy current Joule heating, which acts on the fragrance matrix to volatilize aerosols. The sensor is coupled with the electromagnetic heater to achieve non-contact temperature measurement and control. For a configuration with one fragrance chamber, the electromagnetic heater uses a one-time heating method for fragrance release within a fixed duration. For a configuration with multiple fragrance chambers, the electromagnetic heater uses a centralized overall heating method to rapidly release a large amount of aerosols, or a distributed sequential heating method to slowly release an appropriate amount of aerosols. The electromagnetic heater and induction fragrance proposed in this invention can fully bake the fragrance matrix and efficiently volatilize aroma components, making the entire fragrance generation process clean, hygienic, subtle, elegant, and long-lasting.

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely one embodiment of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Sensing fragrances include a fragrance matrix for generating aerosols and a sensor for sensing, with the fragrance matrix and the sensor in close physical contact.

[0040] The following specific embodiments illustrate the production steps of hair fragrance base. (Refer to...) Figure 1 This embodiment demonstrates a manufacturing process for a hair fragrance matrix using mugwort matrix as an example.

[0041] Step 1 in the spice manufacturing process: separation of stems and leaves. In use, only the leaves are needed. The stems at the tips of the mugwort are easily broken and damaged, and the stems are a non-magnetic material with a high degree of lignification. Therefore, after harvesting the mugwort, the leaves and stems need to be separated.

[0042] Step 2 in the spice manufacturing process: Artemisia floss. Artemisia floss is a soft, fine, cotton-like substance obtained by repeatedly sun-drying, pounding, crushing, and sifting out impurities and dust from Artemisia leaves.

[0043] Step 3 in the spice manufacturing process: moxa wool rolling. Moxa wool is a fine, fibrous material with a low degree of self-polymerization. Therefore, it is usually wrapped with a winding film for compression during the winding process.

[0044] Step 4 of the spice manufacturing process is cutting the moxa sticks. Long moxa sticks are not suitable for use in this embodiment. The moxa sticks are separated into sheet-like moxa cakes by a cutter. The cross-section of the moxa cake is a circle corresponding to the cross-section of the moxa stick, or it can be other shapes, depending on the fixed shape of the compression and winding.

[0045] It should be noted that, in addition to mugwort, the raw materials for the fragrance base mainly include, but are not limited to, one or more of the following: agarwood, sandalwood, musk, ambergris, frankincense, sandalwood, borneol, rosemary, cyperus, safflower, clove, fennel, cardamom, cinnamon, cyperus rhizome, rue, citronella, benzoin, tonka bean, styrax, honeysuckle, wisteria, fragrant grass, patchouli, costus root, scrophularia, ginseng, chuanxiong rhizome, atractylodes, angelica, codonopsis, and amber. Angelica dahurica, calamus, angelica dahurica, mosquito repellent grass, mint, camphor, pine needles, eucalyptus leaves, cypress leaves, bamboo leaves, turmeric, licorice, dried tangerine peel, lemon, olive, perilla leaves, tea, red dates, various fruits or their kernels, flower buds of various flowers or their extracted floral water, alcohol or dealdehyde alcohol, honey, rock sugar, petrolatum, paraffin wax, musk, saltpeter, calcium carbonate, stone powder, cinnamon powder, wood powder, and one or more other Chinese medicinal herbs and herbs that can be used in fragrance.

[0046] The fragrance matrix in this invention is a basic powder formed by using various plant, animal, and mineral fragrances or their extracts as raw materials, which are manually ground or mechanically pulverized and sieved into small particles of different mesh sizes, and then processed through different methods such as fermentation, frying, steaming, drying, mixing, crushing, extrusion, and kneading. The powder itself has the following forms: fine powder with a particle long axis size distribution of 0.02-1 mm, large particles with a particle long axis size distribution of 1.01-4 mm, or fine velvet with a diameter of 0.3-0.9 mm.

[0047] The aforementioned aroma-generating matrix raw materials, after processing, form fragrances. Taking into account roasting time, the size of the fragrance chamber of the electromagnetic heater, and ease of operation, they can have the following forms:

[0048] The fragrance matrix has the following morphology: spherical or ellipsoidal. The diameter of the sphere and the length of the major or minor axis of the ellipsoid are 5-40 mm, preferably 8-20 mm.

[0049] Fragrance matrix morphology 2: cylindrical or similar rod-shaped. The diameter of the cylinder and the diameter of the rod body are 5-30 mm, preferably 8-20 mm; the overall length is 15-35 mm, preferably 20-30 mm.

[0050] Fragrance matrix morphology three: disc-shaped. Its XY plane can be circular, annular, elliptical, equilateral triangle, rhombus, square, rectangle, regular pentagon to regular octagon, star-shaped, or a combination of these shapes, as well as irregular shapes resembling clover, plum petals, etc. The area of ​​these shapes in the XY plane is 625-4900 mm². 2 Preferably 900-2500mm 2 Its Z-axis thickness is 3-15mm, preferably 6-10mm.

[0051] Fragrance base form four: slender incense sticks or round incense coils. The total length of the stick is 40-300mm, preferably 100-200mm; the cross-sectional area of ​​the stick is 1-16mm². 2 4-9mm is preferred 2 .

[0052] The following specific embodiments illustrate different ways in which the receptors and the fragrance matrix are combined. The receptors are tightly combined with the fragrance matrix, either embedded inside the fragrance matrix or arranged on the periphery of the fragrance matrix.

[0053] In this embedded arrangement, one or more receptors are embedded within the fragrance matrix. This heating method involves heat diffusion from the interior or center of the fragrance outwards. For example... Figure 2 As shown, the fragrance matrix is ​​made of a certain fragrance mixture powder, which is heated by the receptors inside to generate an aerosol and thus achieve fragrance dispersion. Figure 2 Figure a shows a cross-sectional view of a spherical fragrance sliced ​​from the center. The receptor 211 is a spherical particle, and multiple receptors 211 are randomly distributed in the fragrance matrix 212 and are densely pressed together with the fragrance matrix 212. Figure 2 Figure b shows a cross-sectional view of a disc-shaped fragrance sliced ​​along the Z direction from the center of the XY plane. A thin, circular sensor 221 is located in the middle of the fragrance matrix 222, forming a sandwich-like structure. Figure 2 Figure c shows a cross-sectional view of a cylindrical fragrance sliced ​​longitudinally from the central axis, with a rectangular thin-film receptor 231 longitudinally disposed in the fragrance matrix 232 along the central axis.

[0054] In the external wrapping arrangement, one or more receptors cover, wrap, or wrap around the surface of the fragrance matrix. This heating method involves heating from the outside in. The micropores or meshes in the receptors serve as auxiliary channels for aerosol dispersal. The number of micropores is greater than two, and they are preferably evenly distributed on the unfolded surface of the receptors. Figure 3 As shown, the fragrance matrix is ​​made of a certain fragrance powder, which is heated by the receptors placed on the periphery to generate an aerosol to achieve fragrance dispersion. Figure 3 Figure a shows a cross-sectional view of a spherical fragrance sliced ​​from the center. The spherical or mesh-like receptors 311 encapsulate the fragrance matrix 313, where 312 are ventilated micropores. Figure 3 Figure b shows a cross-sectional view of a disc-shaped fragrance sliced ​​along the Z direction from the center of the XY plane. Two thin, circular receptors 321 in the XY plane are located on the upper and lower surfaces of the fragrance matrix 323, forming a sandwich-like structure, where 322 is a ventilated micropore. Figure 3Figure c in the figure is a schematic cross-section of a cylindrical fragrance sliced ​​longitudinally from the central axis. The tubular receptors 332 surround the fragrance matrix 333, and 332 are ventilated micropores.

[0055] The sensor can be composed of a single material or multiple composite alloy materials, including a temperature marking material. When the sensor is made of a single alloy material, it has the dual functions of heating and temperature marking. When the sensor is composed of multiple composite materials, different components perform different functions of heating or temperature marking. In this case, the magnetic characteristics of the temperature marking material in the sensor are extremely important for the system's detection, temperature measurement, and temperature control operations. The behavior of the initial permeability of the single material or the temperature marking material as a function of temperature is discussed below.

[0056] The initial permeability μ i It exhibits a peak characteristic as temperature T increases, and the peak characteristic includes, for example: Figure 4 The single-peak characteristic curve shown and / or as shown Figure 5 The bimodal characteristic curve shown is shown.

[0057] refer to Figure 4 , Figure 4 This is a schematic diagram of a single-peak curve, which has a peak of highest permeability M. For this magnetic variation characteristic, the present invention sets the operating temperature Tb of the sensor at point B to the right of the highest permeability peak M, and close to peak M. The corresponding temperature relationship is that Tb is close to T... m Far from Curie temperature T c .

[0058] refer to Figure 5 , Figure 5 This is a schematic diagram of a bimodal curve. For the bimodal curve, as the temperature increases from room temperature T0 (=20℃), the initial permeability μ... i The change will show two peaks, namely the Hopkinson peak M1 and the highest permeability peak M2, when the temperature is further increased to the Curie temperature T. c2 When the magnetism disappears, the present invention addresses this characteristic of magnetic change by adjusting the operating temperature T of the sensor. b1 Setting point B1 to the right of the first peak M1, and adjacent to it, the corresponding temperature relationship is T. b1 Close to T m1 Stay away from T c2 Alternatively, the point can be set at B2 to the right of the second peak M2, and adjacent to the second peak M2. In this case, the corresponding temperature relationship is T. b2 Close to T m2 Stay away from T c2 .

[0059] There are usually no strict precision standards for the aerosol release of fragrances. From the perspective of temperature adaptability and controllability, sensors with single-peak or double-peak characteristic curves are generally applicable. The temperature can be controlled and the duty cycle of the power input can be dynamically adjusted through the preset program of the electromagnetic heater. Dynamic thermal equilibrium can still be achieved under the conditions of external temperature fluctuations and changes in the heating of the fragrance matrix, so as to achieve stable operation.

[0060] The single material or temperature-marking material has a Curie temperature not exceeding 400°C, preferably between 200-400°C. Based on the experimental experience of the present invention and the programming settings of the electromagnetic heater, the corresponding stable operating temperature of the receptor is set between approximately 100-300°C. This temperature range is very suitable for most fragrance-generating matrices, such as artemisia or agarwood: on the one hand, it avoids open flame combustion or scorching of the fragrance; on the other hand, it provides the necessary temperature for efficient baking, thereby fully releasing the aroma. This process can be called efficient aroma diffusion, aroma baking, or aroma appreciation, and is suitable for applications such as in-vehicle use, home use, hotels, tea rooms, and various clubs.

[0061] The aforementioned receptors have low resistivity, typically in the range of 2-30 × 10⁻⁶. -8 Between Ωm (20℃), the eddy current effect is generated quickly under these conditions, which makes the receptor heat up rapidly per unit time, allowing for rapid baking and carbonization of the aroma-generating matrix, producing a rich aerosol.

[0062] The sensor is composed of a single alloy material or a composite material. When the sensor is composed of a single alloy material, its initial permeability exhibits a peak characteristic with increasing temperature in the range from room temperature (20°C) to the Curie temperature. When the sensor is a composite structure composed of multiple alloy materials, the sensor is configured to include a temperature-marking material, and its initial permeability exhibits a peak characteristic with increasing temperature in the range from room temperature (20°C) to the Curie temperature.

[0063] The base material used in this invention for the single material or temperature marking material includes one or more of the following: iron-nickel-zirconium based alloy, iron-nickel based soft magnetic permalloy (such as 1J85), iron-nickel based expansion alloy (such as 4J42) or Invar alloy (such as low expansion iron-nickel alloy), iron-chromium based alloy, aluminum-nickel-cobalt based alloy, or neodymium-iron-boron based alloy; or a series of non-standard alloys with ferromagnetic or subferromagnetic properties formed by modifying the above materials with a small amount of alloying elements.

[0064] In one embodiment, the single material or temperature-marking material is a base alloy formed from the main raw materials iron, nickel, and zirconium, which is a non-standard alloy. Considering the possibility of different metallographic phases formed by the interactions and combinations of the various raw material elements, this invention provides a single material or a composite structural material including a temperature-marking material in an iron-nickel-zirconium-based ternary alloy, wherein the weight percentages are 2.00-35.00% iron, 60.00-90.00% nickel, and 0.40-10.00% zirconium.

[0065] The initial magnetic permeability of this series of alloys has the aforementioned peak characteristics, which can be used as a temperature marker. It can be coupled with the excitation coil in the electromagnetic heater. After reaching a stable operating temperature, the magnetic field still has a heat preservation function, which can achieve stable operation.

[0066] In another embodiment, a small amount of certain alloying elements may be added to the iron-nickel-zirconium-based alloy, which may be the first additive element chromium and / or cobalt, wherein the weight percentages of iron, nickel, and zirconium are 2.00-35.00% iron, 60.00-90.00% nickel, and 0.40-10.00% zirconium, respectively, and the weight percentages of the first additive element raw material are 0.50-20.00% chromium and 0.50-20.00% cobalt.

[0067] Chromium and cobalt are added to the iron-nickel-zirconium-based alloy as the first additive elements in an appropriate ratio, which improves the temperature marking function of the alloy after melting, such as temperature sensitivity. On the one hand, it is used to reduce the initial magnetic permeability of the alloy, and on the other hand, it is used to adjust the Curie temperature to meet the carbonization requirements of different types of fragrance matrices.

[0068] In a further embodiment, small amounts of other alloying elements can be added to the iron-nickel-zirconium-based alloy, which can be considered as secondary alloying elements. The secondary alloying element raw materials include one or more of aluminum, boron, molybdenum, manganese, copper, titanium, neodymium, magnesium, silicon, carbon, niobium, phosphorus, vanadium, gadolinium, lanthanum, and cerium. The weight percentages of iron, nickel, and zirconium are respectively: iron 2.00-35.00%, nickel 60.00-90.00%, and zirconium 0.40-10.00%. The weight percentages of the secondary alloying element are: aluminum 0-8.00%, boron 0- 7.60%, Molybdenum 0-7.20%, Manganese 0-6.00%, Copper 0-4.20%, Titanium 0-3.50%, Neodymium 0-2.80%, Magnesium 0-2.20%, Silicon 0-2.00%, Carbon 0-1.80%, Niobium 0-1.50%, Phosphorus 0-1.00%, Vanadium 0-0.90%, Gadolinium 0-0.80%, Lanthanum 0-0.60%, Cerium 0-0.50%.

[0069] The addition of raw material elements not only makes the smelting and processing process smoother and promotes production efficiency, but also adjusts and improves the characterization function of temperature marking components.

[0070] The aforementioned weight percentage calculation method can accurately identify the content of the raw material elements, the first additive raw material element, and the second additive raw material element of the base alloy using various technical means such as chemical composition analysis, spectral analysis, mass spectrometry analysis, chromatographic analysis, and X-ray atomic energy spectroscopy.

[0071] The arrangement, number, and shape of the receptors in the hair fragrance matrix in the above embodiments can take many forms.

[0072] like Figure 6 The illustration shows an example of a composite receptor embedded within a hair fragrance matrix. Figure 6 Figure a shows two single-layer receptors 611 and 612 made of different materials embedded in the fragrance matrix 613. Both receptors have heating and temperature marking functions. Figure 6 The receptor 621 shown in Figure b is made of multi-layer composite materials A, B, and C. Figure 622 is an enlarged cross-sectional view of the receptor 621. Materials A, B, and C have heating, temperature marking, and anti-corrosion functions, respectively. They form the receptor components and are arranged in the fragrance matrix 623.

[0073] like Figure 7 The illustration shows an example of embedding a single receptor within the hair fragrance matrix. Figure 7 Figure a shows a single-layer receptor 711 made of a single material, embedded in the fragrance matrix 712. When the fragrance is prepared with an axial length greater than its radial length, the mechanical strength of the receptor is not high, and insertion is difficult. Figure 7 The slender, thin-film sensor shown in Figure a presents a significant challenge. In this case, inserting two sensors 721 from opposite ends along the axial direction to work together to generate heat is a feasible solution. Figure 7 As shown in Figure b, although there are two receptors in the fragrance matrix 722, both receptors are single-layer receptors made of the same single material.

[0082] The following specific embodiment is a schematic diagram of the electromagnetic heater part.

[0083] Figure 8 This is a schematic cross-sectional view of an electromagnetic heater using a planar disc coil. Figure 9 This is a schematic diagram of a cross-section of an electromagnetic heater that uses a three-dimensional helical tubular coil.

[0084] Reference Figure 8 , Figure 8This is a schematic diagram of the structure of an electromagnetic heater with a planar disc-shaped coil. In its specific implementation, the XY plane of the coil is parallel to the surface of the electromagnetic heater, and the fragrance is located on the upper surface of the coil, close to the XY plane. The basic hardware components of the electromagnetic heater include a circuit board assembly and battery unit 88, a support component 86, an electromagnetic shielding cover 87, a coil 89, a heat insulation layer 83, an operation panel 85, and a perforated cover plate 82. The circuit board assembly includes multi-layer rigid and / or circuit boards, integrating high-density interconnected chips and components, and serving as the software carrier for the control program. It can realize multiple functions such as switching, charging and discharging, anti-counterfeiting identification, heating, temperature measurement, and temperature control. The battery unit includes a polymer lithium-ion rechargeable battery, providing power output to the circuit and enabling multiple charge-discharge cycles. The support component 86 is mainly made of plastics and resins, such as polyphenylene sulfide, polyethersulfone, polyamide, polybutylene terephthalate, acrylonitrile-butadiene-styrene copolymer, and various glass fiber reinforced plastics, etc., and is easy to assemble, providing component protection and effective heat dissipation. The electromagnetic shielding cover 87 includes a soft magnetic alloy and a ferrite nanocrystalline magnetic shielding layer, which isolates part of the electromagnetic field generated by the coil to prevent electromagnetic interference to the circuit board assembly. The coil 89 is a single-turn or multi-turn enameled copper wire, silver-plated copper wire, aluminum wire, or silver wire, and its shape is filamentous or strip-shaped. It has a high no-load quality factor q value in the frequency range of 30K-20M Hz (low loss during operation). Under the high-frequency alternating magnetic field excitation in the frequency range, the sensor 84 embedded in the fragrance matrix 81 generates heat due to a strong eddy current effect. The sensor 84 is detected, anti-counterfeiting, temperature measurement, and temperature control functions are realized by detecting the change in inductance related to the change in initial permeability. The heat insulation layer 83 is made of high heat-resistant microcrystalline glass, polyetheretherketone resin, mica sheet, or aerogel cloth, etc., to provide necessary heat insulation for the fragrance chamber to protect the coil, circuit board assembly, battery, and other units. The control panel 85 assists in a series of operations such as switching on / off, temperature settings, modes, and colored lights, and can display usage parameters or status such as time, temperature, and battery level. The perforated cover plate covers the fragrance and provides an unobstructed aerosol evaporation channel.

[0085] In a simplified electromagnetic heater, the aforementioned components are not essential; that is, the heating function can still be achieved even by omitting some non-core components. For example, the electromagnetic heater mainly includes a coil, an electromagnetic shield, a support structure, a control unit, and a power supply, without numerous display and control components. The coil and control unit are electrically connected to form an electromagnetic coupling circuit. The electromagnetic shield is located near or around the coil to isolate electromagnetic interference. The coil and support structure are combined to form a fragrance chamber for holding fragrances.

[0086] like Figure 9The diagram shows a schematic of an electromagnetic heater using a three-dimensional helical coil. In a specific implementation, the axis of the coil is perpendicular to the surface of the electromagnetic heater, and the spices are surrounded by the coil.

[0087] The basic hardware components of this electromagnetic heater include circuit board assembly and battery unit 97, support component 95, electromagnetic shielding cover 98, coil 99, heat insulation layer 92, operation panel 94, and perforated cover plate 93, etc. The specific structural contents and working principle are similar to those of the previous model. Figure 8 The electromagnetic heater illustrated in the diagram is similar and will not be described in detail here.

[0088] It should be noted that the electromagnetic heater may contain one spice chamber or multiple distributed spice chambers, where "multiple" refers to no more than six. For multiple distributed spice chambers, multiple coils can be configured accordingly. In this case, the electromagnetic heater can simultaneously hold multiple spices with the same or different aromas, and a control program can be set to perform distributed sequential heating. After reaching the cumulative heating timer, the heater switches to heating different spices.

[0089] Furthermore, the control circuit diagram of the electromagnetic heater is as follows: Figure 10 As shown. The control circuit includes a power supply VCC, a first resonant inductor L1, a second resonant inductor L2, a first resonant capacitor C1, a second resonant capacitor C2, and a resonant charging control switch Q1. One end of the second resonant inductor L1 is connected to the power supply VCC. The other end of the second resonant inductor L2 is connected to the first resonant capacitor C1, the second resonant capacitor C2, and one end of the first resonant inductor L1. The other end of the second resonant capacitor C2 is connected to ground. The other end of the first resonant inductor L1 is connected to the other end of the first resonant capacitor C1 and is connected to the drain of the resonant charging control switch Q1. The source of the resonant charging control switch Q1 is connected to ground.

[0090] In practical implementation, the control circuit operates as follows: It uses a synchronous circuit or the analog-to-digital converter (ADC) of a microcontroller unit (MCU) to compare the voltage levels at positions x1 and x2, thereby controlling the on / off state of the resonant charging control switch Q1. The control circuit has two resonant circuits: Resonant circuit 1 consists of a first resonant inductor L1 and a first resonant capacitor C1; resonant circuit 2 consists of a first resonant inductor L1, a first resonant capacitor C1, and a second resonant capacitor C2. The temperature change of the sensor causes a change in the inductance of the first resonant inductor L1, resulting in a change in the parameters of the resonant circuit. This allows for the measurement of the peak value of the resonant period, thus determining the stable operating temperature of the sensor, which is located to the right of and close to a certain peak value.

[0091] It should be noted that the single material or temperature marking material used in this embodiment has a certain initial magnetic permeability at room temperature (20°C). When it is placed in the electromagnetic field of the first resonant inductor L1 (i.e., the coil), it will cause a change in the inductance of the first resonant inductor L1. In the detection program, a threshold or multiple target conditions for the current change behavior caused by this change in inductance are preset, so as to determine whether the correct sensor is placed, so as to realize the detection and anti-counterfeiting identification functions. Accordingly, normal operation program can be started or protection measures can be triggered.

[0092] based on Figure 5 The peak characteristics described herein show that in the early stages of heating, the initial permeability increases with rising temperature, then decreases after reaching peak point N, followed by an increase, and then rapidly decreases after reaching peak point M2. Around peak point N or M2, from left to right of a given peak, the circuit switches between two resonant loops: half a cycle in loop 1 and the other half in loop 2. A schematic diagram of the time t of a single resonant cycle of resonant loop 1 versus sensor temperature is shown below. Figure 11 As shown, the coil inductance L1 changes with the temperature-dependent initial permeability. When L1 increases, the cycle time of the corresponding resonant circuit 1 increases; when L1 decreases, the cycle time of the corresponding resonant circuit 1 decreases. This causes the cycle time detected by the synchronization circuit or the MCU's ADC to change, thus achieving precise temperature measurement and control. The sensor's operating temperature is controlled to the right of the peak temperature point, and a dynamically balanced operating state is achieved by adjusting the duty cycle of the power input.

[0093] The following are specific experimental examples of the fragrance aerosol generation system.

[0094] In this experimental example, three solid fragrances with classic scents were prepared: No. 001 Lingbo Xianyun Fragrance (round cake), No. 002 Han Jianning Palace Fragrance (spherical), and No. 003 Goose Pear Tent Fragrance (cylindrical). Their main raw materials are shown in Table I.

[0095] Table I: Main Raw Materials of Three Classic Solid Fragrances

[0096]

[0097] Fragrances No. 001, 002, and 003 are formulated using a heating method where receptors are embedded within the fragrance matrix, respectively corresponding to... Figure 2 The three methods described herein aim to produce three fragrances with similar volumes as much as possible in the experiment. The goal of this invention in practical applications is to use a relatively simple structural form to facilitate the fragrance manufacturing process and operation during heating.

[0098] The disc-shaped fragrance has a Z-axis height of 4.3 mm and a diameter of 12 mm in the XY plane. The receptor is a composite circular sheet, constructed from a double-layer material of stainless steel 430 and a corrosion-resistant soft magnetic alloy. Here, the stainless steel 430 primarily functions as a heat source, while the corrosion-resistant soft magnetic alloy serves as a temperature marking material. Its Z-axis height is 0.2 mm, and its diameter in the XY plane is 10 mm. Correspondingly, the volume of the fragrance matrix and the receptor are 470.3 mm². 3 and 15.7mm 3 The single receptor is located at the center of the fragrance in the Z-axis direction, parallel to the surface of the fragrance.

[0099] The spherical fragrance particles have a diameter of 10 mm. Within them are 60 randomly distributed small iron-nickel-zirconium alloy spheres with a diameter of 0.8 mm, serving as single-alloy component receptors and simultaneously functioning as heat generators and temperature markers. Correspondingly, the volumes of the fragrance matrix and the receptors are 471.0 mm². 3 and 16.1mm 3 .

[0100] The cylindrical fragrance has a Z-axis height of 9.4 mm and a diameter of 8.2 mm in the XY plane. A single rectangular sheet of low-expansion iron-nickel alloy is inserted at the axial center as a sensor, which also functions as a heat generator and temperature marker. Its dimensions are 9.4 mm long x 6.5 mm wide x 0.25 mm thick. Correspondingly, the volumes of the fragrance base powder and the sensor are 472.3 mm². 3 and 15.3mm 3 .

[0101] In this invention, the heating power is adjusted, and the real-time temperature of the sensor is fed back through the aforementioned electromagnetic coupling loop system. This is further verified by infrared non-contact temperature measurement of the outer surface of the fragrance. The sensor's operating temperature is set at three different points: approximately 150°C, 200°C, and 350°C. The expected average temperature of the corresponding fragrances is around 50°C, 100°C, and 250°C, respectively. Heating and baking experiments were conducted on the three fragrances listed in Table I using these three temperature settings.

[0102] Aroma concentration is related to the heating and baking temperature and the cumulative heating time. In an extreme case, for example, after baking spices for several hours at a sensor operating temperature of approximately 350°C, the aroma components may be depleted, and if heated further, the aroma emitted by the spices will be almost undetectable. The goal of this invention in practical applications is to achieve a baking life of approximately 4 hours for the spices, meaning that a noticeable aroma release is maintained throughout the 4 hours of continuous baking.

[0103] In this invention, the aforementioned fragrance was heated cumulatively in a fixed room for 4 hours. Every 0.5 hours, a participant smelled the aroma, and the concentration of the fragrance was subjectively compared. After each smelling, the participant moved away from the aromatherapy room and then smelled coffee beans to "cleanse" their nose and improve their sensitivity for the next smelling. The aroma concentration levels are defined as "strong," "medium," and "weak," corresponding to intense, delicate, and faint aromas, respectively. In practical application, this invention aims to achieve the "medium" level of delicate aroma.

[0104] After verification, all three sensor configurations in Table I can be used to achieve the functions of detection, identification, heating, temperature measurement and temperature control.

[0105] Comparative analysis of the aromatherapy effects revealed that a sensor operating temperature of around 200℃ is suitable for roasting the three types of fragrances listed in Table I. This results in a more uniform and lasting aroma release; specifically, throughout the 4-hour heating process, the emitted aroma remains at a "medium" concentration, with a slight decrease in olfactory perception over time. Based on this, in practical applications, the 4-hour period can be divided into four average time intervals, corresponding to a plateau-step temperature curve, such as 200℃, 210℃, 220℃, and 230℃. This compensates for the loss of some of the effective components after the fragrance matrix evaporates, thus maintaining a more uniform and stable aroma concentration throughout the 4-hour period.

[0106] When the receptors are set to operate at approximately 150°C and 350°C, these represent two relatively extreme conditions. At approximately 150°C, the fragrance release is very slow, remaining at a "weak" level for about 3 hours, and then at a "medium" level from about 3 hours until 4 hours later. Therefore, low-temperature applications at around 150°C are generally only suitable for home settings where the speed of fragrance release is not critical. In this case, the fragrance lasts longer, up to about 8 hours or even longer. Conversely, when baking at around 350°C, a very strong "strong" fragrance is present for about 0.5 hours, but becomes almost undetectable after about 1 hour. This high temperature is only suitable for applications requiring a quick and intense fragrance, with a shorter duration of about 1 hour.

[0107] To further test the heating rate of this fragrance aerosol generation system, this experiment also used a three-dimensional helical tubular coil to electromagnetically excite and characterize a thin-film iron-nickel soft magnetic alloy sensor. In this case, the iron-nickel soft magnetic alloy simultaneously served as a heating element and a temperature marker. Since infrared thermometry detects surface temperature, a bare coil and bare sensor were directly inserted into the coil to calibrate the stable operating temperature immediately after application. A Mag32 infrared imager was used to monitor the bare coil and bare sensor. It was found that within approximately 74 seconds of system startup, the sensor's maximum temperature rapidly increased to and remained at approximately 300°C. The temperature distribution under dynamic stability is shown in [Figure showing...]. Figure 12 .

[0108] The invention also experimentally verified the roasting effect of mugwort spices. A thin-film sensor made of iron-nickel soft magnetic alloy was used as a heat source to conduct a long-term roasting test on columnar mugwort cakes. The initial permeability of the iron-nickel soft magnetic alloy exhibits the aforementioned single-peak characteristic, with a Curie temperature of approximately 400℃. Its permeability reaches its peak at approximately 300℃ and then begins to decline. Therefore, the sensor can be stably operated at around 300℃. Figure 13 This is a picture of the mugwort spice after it was baked at the receptor working temperature of 300℃ for 0.5 hours and then cut open. It was found that the carbonization of the mugwort floss was very thorough. Under these conditions, the aroma and pharmacological components of the mugwort floss should have been effectively released as expected through heating without combustion.

[0109] The embodiments disclosed in this invention are merely specific examples for the purpose of clearly illustrating the invention and should not be regarded as limiting the scope of the invention. Of course, they should not be used to limit the scope of the claims of this invention. For those skilled in the art, equivalent changes, modifications, variations, etc., made in accordance with the claims of this invention without creative effort are still within the scope of this invention and should be included within the protection scope of the claims of this invention.
