Description

TECHNICAL FIELD

[0001] The present application relates to the field of atomization, in particular to a solid essence, a preparation method thereof and an electronic atomization device. BACKGROUND

[0002] Currently, the essence in the atomization substrate is mainly mixed in the PG / VG tobacco tar in the form of liquid, but there are problems such as easy volatilization, decomposition and migration of aroma components during storage or heating, resulting in unstable aroma, flavor fading from front to back, and poor user experience. At present, it is mainly relied on to select essence components with stronger thermal stability and lower volatility to reduce the loss in the high-temperature atomization process; or, by adjusting the PG / VG ratio to improve the solubility of the essence; or, using special carriers (such as MCT oil) to reduce migration and volatility. In addition, by reducing the atomization temperature (such as using ceramic core low-temperature atomization), reducing thermal decomposition, enhancing flavor persistence, and adding an independent essence tank outside the main oil tank, setting different release times, and realizing uniform release. The essential oil is stored in a separate barrier layer, which can gradually release the aroma through physical diffusion or active mixing.

[0003] However, the use of the above scheme in the electronic atomization device will cause the reduction of the taste restoration degree, for example, some high-boiling-point, high-thermal-stability essence components may not be easy to volatilize, resulting in insufficient aroma after atomization and poor flavor performance; some high-stability essence components have poor solubility in PG / VG solution, which may cause precipitation or uneven distribution. Therefore, due to the difficulty of volatilization of the essence, the user may not feel enough aroma when smoking the first few puffs, resulting in poor experience. SUMMARY

[0026] The application will be described in further detail below with specific reference to the drawings. Like elements in different embodiments are denoted by like reference numerals. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the application. However, it will be apparent to one skilled in the art that some features, which are not necessarily the most important to implementation, can be left out without a corresponding loss of understanding. In the description, relative terms are used to describe the orientations of the components. These terms are used only to more clearly describe the embodiments and are in no way a limitation on the scope of the application.

[0027] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. Meanwhile, the steps or actions in the method description can also be sequentially adjusted or changed in a manner that is apparent to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that the sequence is necessary, unless otherwise stated that a certain sequence must be followed.

[0028] The serial numbers of components in this document, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any sequence or technical meaning. The "connection" and "coupling" in this application include direct and indirect connections (couplings) unless otherwise specified.

[0029] The application provides a solid flavor and a preparation method thereof and an electronic atomization device.

[0030] In an embodiment of the application, the solid flavor is arranged in a liquid storage cavity of the electronic atomization device, and the solid flavor includes an adsorption carrier, a flavoring substance and a binder. The adsorption carrier is used to adsorb the flavoring substance, and the binder is used to bind and shape the adsorption carrier.

[0031] The use of the adsorption carrier to adsorb the flavoring substance can reduce the volatile loss of the flavoring substance, improve the aroma storage concentration, and optimize the user experience. In addition, the binder used in the application has very low solubility in PG and VG. The use of the binder to bind the carrier can achieve slow release of the flavor, so that the aroma concentration in the aerosol of the electronic atomization device can be continuously maintained at a relatively stable level, solving the industry pain point of "high concentration at the beginning and low concentration at the end".

[0032] In the embodiment, the adsorption carrier includes at least one of porous starch, beta-cyclodextrin, starch, maltodextrin, galactan, galacturonic acid, polyethylene glycol, activated carbon, zeolite, volcanic rock, porous silica ceramic, plant puffed particles, plant ultra-fine powder, pullulan ester, chitosan and waxy material.

[0033] In the application, for example, porous starch is used as the adsorption carrier. Because the porous starch has a large number of pores and a loose internal structure, it has good adsorption and better locks the aroma of the essence, thereby prolonging the shelf life of the solid essence.

[0034] The plant puffed particles are obtained by a plant puffed process. The plant puffed process is a high-temperature and high-pressure instantaneous puffing (extrusion) technology. The plant puffed particles have a porous structure. The plant puffed raw materials include corn, wheat, rice, oat, soybean, pea, broad bean, konjac, sweet potato, cassava, fruit and vegetable residues, plant cellulose, bitter buckwheat, buckwheat, millet, Chinese medicine residues, herbal plants (such as dandelion and chrysanthemum) and the like.

[0035] The plant ultra-fine powder is obtained by airflow pulverization, mechanical impact, frozen pulverization and the like. The particle size of the plant ultra-fine powder is usually less than 100 μm. The plant raw materials of the plant ultra-fine powder include tea powder, green tea powder, matcha powder, ganoderma lucidum, cordyceps, ginseng, radix astragali, citrus peel, lemon peel, rose petal powder, wood powder, bamboo powder, fruit shell powder, activated carbon powder, pollen, alfalfa and perilla and the like.

[0036] The waxy material includes microcrystalline wax, polyethylene wax, Brazil palm wax mixture, beeswax, paraffin insect wax, lanolin, candelilla wax and the like.

[0037] The binder includes at least one of tamarind polysaccharide gum, polyvinyl alcohol, hydroxypropyl methyl cellulose, xanthan gum, sodium alginate, gum arabic, gelatin, polylactic acid, stearic acid and monoglyceride.

[0038] The flavoring substance includes edible essence. The specific flavor type can be adjusted according to user demand, which is not described herein.

[0039] In the embodiment, the mass ratio of the adsorption carrier to the binder is 3:1 to 5:1.

[0040] If the proportion of the adsorption carrier is too high (the amount of the binder is too small), the solid flavor structure will be loose and fragile, the flavor will be released too quickly and unevenly, the taste will be strong at the beginning and weak at the end when heated, and the product stability will be reduced due to insufficient adhesion for processing and molding. If the proportion of the adsorption carrier is too low (the amount of the binder is too large), the flavor release will be blocked, the taste will be weak, and the product hardness will be too high and the suction resistance will be increased due to the excessive amount of the binder, and harmful pyrolysis products will be generated at high temperatures, affecting safety and user experience. In the present application, the mass ratio is controlled at 3:1-5:1, which can balance the flavor loading capacity, structural strength and release efficiency, ensure uniform release of the flavor when heated, and maintain the physical properties and safety of the product.

[0041] In an embodiment of the present application, a preparation method of a solid flavor is provided for preparing the aforementioned solid flavor, comprising: obtaining a carrier suspension comprising an adsorption carrier, and a flavor solution comprising flavoring substances; mixing the carrier suspension and the flavor solution and adding a binder to obtain a mixed slurry; and drying and dry-pressing the mixed slurry to obtain the solid flavor.

[0042] The solid flavor obtained by the preparation method of the present application can reduce the loss of volatile aroma and improve the storage concentration of the aroma, because the adsorption carrier adsorbs the flavoring substances. The release speed of the aroma can be slowed down by the adhesion and molding of the adsorption carrier by the binder and the molding of the mixed slurry, so that the aroma concentration of the solid flavor can be continuously and stably output, solving the industry pain point of the aerosol aroma "strong at the beginning and weak at the end" in the electronic atomization equipment.

[0043] In this embodiment, the carrier suspension further comprises a first solvent, and the first solvent comprises water. The flavor solution further comprises a second solvent, and the second solvent comprises at least one of propylene glycol and ethanol.

[0044] The use of water as the first solvent can safely disperse the adsorption carrier and maintain the stability of the slurry, and the use of propylene glycol or ethanol as the second solvent can efficiently dissolve the flavoring substances and adjust the volatilization rate, so that the combination of the two can ensure uniform loading and fixation of the flavor, meet the production requirements of low residue and high compatibility, and meet the performance requirements of the electronic atomization equipment for heating and atomization.

[0045] In an embodiment of the present application, an electronic atomization equipment is provided, please refer to Figures 1-4 The electronic atomization equipment further comprises a liquid storage cavity 260 and the aforementioned solid flavor, and the solid flavor is arranged in the liquid storage cavity 260. The liquid storage cavity 260 is used for storing an atomization substrate, and the liquid storage cavity 260 defines an atomization channel for generating an aerosol.

[0046] By setting the solid essence and the atomization substrate in the liquid storage cavity 260, the solid essence and the atomization substrate are mixed conveniently. However, the solid essence is pressed into a shape, and thus cannot be dissolved in the atomization substrate quickly, but is released slowly, thereby prolonging the release time of the essence and keeping the concentration of the aroma output stable and sustained.

[0047] In an embodiment of the present application, referring to Figures 1-2 , the electronic atomization device further comprises a liquid storage member 100, which is arranged in the liquid storage cavity 260 and comprises a receiving cavity 110 and an atomization channel 120 arranged along the thickness direction of the liquid storage member 100, and the solid essence is arranged in the receiving cavity 110. The thickness direction of the liquid storage member 100 is parallel to the axial direction of the electronic atomization device. The receiving cavity 110 is arranged along the thickness direction of the liquid storage member 100, specifically, the extension direction of the receiving cavity 110 is parallel to the thickness direction of the liquid storage member 100, or the extension direction of the receiving cavity 110 intersects with the thickness direction of the liquid storage member 100 at an acute angle. When the solid essence is arranged in the receiving cavity 110, the uniform diffusion of the flavoring substances is facilitated, and the user experience is improved.

[0048] By arranging the solid essence modularly on the liquid storage member 100, when the liquid storage member 100 is arranged in the electronic atomization device, the solid essence is arranged separately and is gradually released in the atomization substrate by physical diffusion, which prolongs the preservation time of the aroma of the solid essence, realizes temperature-controlled release, and reduces flavor loss without interfering with the components of the atomization substrate.

[0049] In an embodiment of the present application, referring to Figures 3-4 , the liquid storage cavity 260 is provided with a partition plate 210, which is used to divide the liquid storage cavity 260 into a liquid storage space 220 and the receiving cavity 110, and the partition plate 210 is provided with a through hole 230 to communicate the liquid storage space 220 and the receiving cavity 110. The solid essence is arranged in the receiving cavity 110, the liquid storage space 220 is used to store the atomization substrate, and the atomization channel 120 is formed in the liquid storage space 220.

[0050] By arranging the partition plate 210 and the through hole 230 on the partition plate 210, that is, by arranging a contact barrier between the solid essence and the atomization substrate, the solid essence can be released in the atomization substrate without being soaked in the atomization substrate excessively, which facilitates the slow release of the solid essence, prolongs the preservation time of the aroma of the essence, realizes temperature-controlled release, and reduces flavor loss without interfering with the components of the atomization substrate.

[0051] Referring to Figure 2 or Figure 4 , the electronic atomization device comprises two or more solid essences, which are arranged uniformly around the circumferential side of the atomization channel 120.

[0052] By uniformly arranging the accommodating cavities 110 around the atomization channel 120, the solid essence can be arranged in the accommodating cavities 110, so that the solid essence in the atomization matrix at all positions in the liquid storage cavity 260 is more uniformly distributed, and the user's smoking taste is improved.

[0053] It can be understood that in other embodiments, the accommodating cavities 110 can be arranged around the atomization channel 120, for example, four accommodating cavities 110 can be arranged, and one solid essence is arranged in each of the accommodating cavities 110.

[0054] Please refer to Figures 1-4 The electronic atomization device includes a liquid storage bin 200, the liquid storage bin 200 includes oppositely arranged inner walls 240 and outer walls 250, the inner walls 240 and the outer walls 250 are arranged to form a liquid storage cavity 260, the atomization channel 120 is located inside the inner walls 240, and the minimum distance between the solid essence and the outer walls 250 is less than the minimum distance between the solid essence and the inner walls 240.

[0055] The atomization channel 120 is provided with an atomization core, and the solid essence is arranged relatively far away from the atomization channel 120, so that the heat generated by the atomization core does not affect the stability of the solid essence due to the close distance between the solid essence and the atomization channel 120, the solid essence is excessively released in the early stage, and the subsequent aroma release concentration is affected.

[0060] The mixed solution preparation step is as follows: the flavor solution is slowly added to the porous starch suspension while stirring, 10 parts by mass of tamarind polysaccharide gum is added at the same time, and a homogenizer is used for stirring at a speed of 1000 rpm for 2 h to obtain a mixed slurry.

The data shown in table 5 and Figure 9

[0096] Table 5

[0097]

[0098] Analysis of experimental results

[0099] As can be seen from the data in table 1 and Figure 5 The average value of the adsorption rate of the porous starch carrier to the fragrance is 76.04%, which is at a high level, and can adsorb sufficient fragrance, better lock the aroma of the fragrance, and prolong the shelf life of the solid fragrance.

[0100] As can be seen from the data in table 2 and Figure 6 The TPM of the first 1000 aerosols is basically 7 mg / puff, and the average value is 7.09 mg / puff, which shows that the fragrance is set in the electronic atomization equipment in the form of solid fragrance, which can improve the stability of the fragrance, ensure stable release of the fragrance, and prolong the shelf life of the fragrance.

[0101] As can be seen from the data in table 3 and Figure 7 For the electronic atomization equipment with a liquid storage member, by introducing solid fragrance, the aroma decay is reduced in the whole pre-suction, middle and post-suction stages, and the aroma concentration in the post-suction stage is only reduced by about 10% compared with that in the pre-suction stage. Specifically, the aroma of the electronic atomization equipment with a single fragrance is reduced by 12.6%, and the aroma of the electronic atomization equipment with two fragrances is reduced by about 11.7%. Compared with comparative example 1, since comparative example 1 does not have a good aroma retention means, the aroma decays quickly during the whole suction, and the aroma concentration in the post-suction stage of comparative example 1 is reduced by 39.6% compared with that in the pre-suction stage, which is much larger than that of the electronic atomization equipment of examples 2 and 3.

[0102] For the electronic atomization equipment with a liquid storage member (not provided with a liquid storage member), such as examples 4 and 5, the aroma concentration in the post-suction stage of the electronic atomization equipment provided with a single solid fragrance is reduced by 13.3% compared with that in the pre-suction stage, and the aroma concentration in the post-suction stage of the electronic atomization equipment provided with two solid fragrances is reduced by 11% compared with that in the pre-suction stage. The aroma concentration in the post-suction stage of the electronic atomization equipment of comparative example 2 is reduced by 50.6% compared with that in the pre-suction stage, which is also much larger than that of the electronic atomization equipment provided with solid fragrances.

[0103] ​In summary, e-vaporizers with a liquid reservoir (without a liquid reservoir) experience faster aroma decay compared to those with a liquid reservoir. Furthermore, the aroma decay rate of e-vaporizers that directly mix flavoring with the atomizing matrix is ​​significantly higher than that of e-vaporizers that incorporate solid flavoring. This is because the use of binders and compressed solid flavoring allows for the slow release of aroma substances, prolonging the aroma release time and ensuring a stable aroma output, thus solving the problem of "strong initial aroma followed by weak aroma" in e-vaporizers.

[0104] From Table 4 and Figure 8 The aroma concentration data of the first 200 puffs of the electronic atomizing device show that, after accelerated environmental testing, the aroma concentration of the atomized atomizers in Comparative Examples 1-2 decreased significantly. However, the aroma concentration of the atomizer with added solid flavoring decreased significantly less. Furthermore, the aroma concentration of the atomizer in the reservoir type (without a reservoir) decreased more significantly than that in the reservoir type. This further demonstrates that placing the flavoring in solid form within the reservoir 100 or reservoir 200 can improve the stability of the flavoring, reduce evaporation loss, and allow for a more stable release of the flavoring aroma.

[0105] Meanwhile, the test results of aroma retention in Tables 3 and 4 show that, compared with the electronic atomization device with a liquid storage chamber (without a liquid storage chamber), the liquid storage chamber structure has less aroma evaporation, higher aroma stability, and longer aroma retention time.

[0106] From Table 5 and Figure 9 It can be seen that the aerosol flavor of e-vaporizers with solid flavorings is generally better than that of e-vaporizers without solid flavorings in Comparative Examples 1-2. This is because the liquid flavorings in Comparative Examples 1-2 are volatile and unstable in storage. The aroma and flavor evaluation of e-vaporizers with liquid reservoirs is generally better than that of e-vaporizers with storage tanks (without a liquid reservoir). This further confirms that the flavorings in e-vaporizers with storage tanks (without a liquid reservoir) are more volatile, resulting in a weaker aroma.

[0107] This application employs a receiving cavity 110 on the liquid storage component or liquid storage tank 200, and places solid flavorings inside the receiving cavity 110, allowing customers to change different flavors according to their personal preferences, thereby increasing the fun of electronic atomization devices. At the same time, it uses porous starch, porous ceramics, and food-grade polymers as carriers, which makes the flavoring release more uniform and has better high temperature resistance and solubility, thus solving the instability problem caused by the traditional mixing of liquid flavorings and atomization matrix.

For the skilled in the art to which the present invention belongs, according to the idea of the present invention, several simple deductions, deformation or replacement can be made.
