Description

Technical Field

[0001] The present invention relates to the field of electronic atomization, and in particular to a magnetic response-releasing electronic atomization liquid and a preparation method and application thereof. Background Art

[0002] With the widespread development of electronic atomization technology, electronic atomization technology has been widely used in the fields of medicine, electronic cigarettes, etc. In the field of medicine, Chinese medicine has become an important factor for patients to be reluctant to take Chinese medicine because of its strong herbal flavor. In addition, traditional medicines are generally swallowed, which makes it extremely difficult for children and the elderly to take them. Electronic atomization liquid is an emerging atomization technology that generates aerosols for human inhalation by heating atomization liquid. If traditional medicines are atomized for patients to take, it will effectively eliminate the resistance of children to taking medicines and the safety hazards caused by the elderly swallowing medicines.

[0003] Compared with traditional cigarettes, electronic cigarettes are loved by cigarette lovers all over the world because they do not contain carcinogens such as tar and have rich flavors. Flavors and flavors are added to the atomizing liquid of electronic cigarettes. The volatility of flavor and flavor molecules is uncontrollable. During use, there is generally a phenomenon of poor durability and durability. As the number of puffs increases, due to sensory fatigue and the reduction of flavor substances in the atomizing liquid, the taste of the atomizing liquid decreases, which greatly affects the consumer's smoking experience. However, there is no effective way in the prior art to solve the problem of taste attenuation of the atomizing liquid caused by the increase in the number of puffs. In addition, different groups of people have different requirements for taste intensity, and the existing atomizing liquid cannot achieve adjustable release of taste intensity, and cannot meet the taste needs of different groups of people. Summary of the invention

[0004] In order to overcome the problems existing in the prior art, one of the objectives of the present invention is to provide an electronic atomization liquid.

[0005] A second object of the present invention is to provide a method for preparing electronic atomization liquid.

[0006] A third object of the present invention is to provide an electronic atomization device.

[0007] A fourth object of the present invention is to provide an application of electronic atomization liquid in the field of electronic atomization.

[0008] In order to achieve the above object, the technical solution adopted by the present invention is:

[0009] The first aspect of the present invention provides an electronic atomization liquid, comprising the following components in weight percentage: 90-99.99% polyol, 0.01-10% magnetic responsive microcapsules; the magnetic responsive microcapsules contain magnetic responsive materials; the magnetic responsive materials include at least one of magnetic responsive metal ions and magnetic responsive metal oxide nanoparticles. The magnetic responsive material in the present invention refers to a material that heats up under the action of a magnetic field.

[0010] On the one hand, the electronic atomization liquid in the present invention can achieve controlled release. There are two ways to release the magnetic responsive microcapsules, specifically: (1) Under the action of a high-frequency (tens to hundreds of MHz) magnetic field, the magnetic responsive material in the magnetic responsive microcapsule generates local heat and destroys the microcapsule structure, thereby achieving controlled release of the microcapsule. (2) Under the action of a low-frequency alternating magnetic field, the magnetic responsive material moves locally under the action of the magnetic field, causing the microcapsule structure to change, thereby achieving controlled release of the microcapsule. On the other hand, the occurrence of taste attenuation caused by an increase in the number of puffs can be avoided. The magnetic responsive microcapsule contains a magnetic responsive material, which enables the microcapsule to slowly release the active ingredient under the action of the magnetic field and be heated and atomized. The amount of the active ingredient (i.e., the core material) in the atomized aerosol is controlled by the magnetic field, so that the amount of the active ingredient in the aerosol remains constant or increases with the extension of the puffing time, thereby avoiding the occurrence of taste attenuation. In addition, different types of electronic atomization liquids with different magnetic properties (for example, different fragrances or different drugs) can be prepared by adjusting the type and content of the magnetically responsive material in the microcapsule, and then these electronic atomization liquids can be mixed. When used, the magnetic field can be adjusted to selectively release specific types of microcapsules according to the needs of different users. For example, orange-flavored electronic atomization liquid and lemon-flavored electronic atomization liquid with different magnetic strengths are mixed and used, and then when the user wants to use the orange-flavored electronic atomization liquid, the orange-flavored electronic atomization liquid is selectively released through magnetic field regulation, thereby achieving the selective release of the core material in the magnetically responsive microcapsule according to the preferences of different users.

[0011] Preferably, the wall material of the magnetically responsive microcapsule comprises a magnetically responsive material.

[0012] Taking the total mass percentage of the magnetic responsive microcapsules as 100%, the mass percentage of the magnetic responsive material is 0.1-5%.

[0013] Preferably, the core material of the magnetically responsive microcapsule includes at least one of a drug, a fragrance base, and a tobacco flavoring agent. The fragrance base contains unstable components such as esters and aldehydes, which are easy to volatilize or oxidize and deteriorate under high temperature conditions, resulting in the disappearance of the fragrance flavor characteristics when the electronic atomization liquid forms an aerosol, and there is a phenomenon of poor persistence and durability, and even unpleasant odors such as "fermentation taste". Therefore, the present invention uses magnetically responsive microcapsules to embed the core materials such as fragrance bases, which can completely solve the problem of fragrance base volatilization, and thus solve the problem of poor persistence and durability of fragrance bases. On the other hand, the use of magnetically responsive microcapsules to embed the core material can also achieve the controlled release of the microcapsules, thereby meeting the taste intensity and taste diversity needs of different consumers.

[0014] Preferably, the medicine includes Chinese medicine or Western medicine. Chinese medicine has a pungent smell, and many patients resist swallowing Chinese medicine. The present invention can encapsulate the medicine by magnetic responsive microcapsules to avoid the pungent smell of Chinese medicine.

[0020] Preferably, the polyphenol is at least one selected from compounds containing phenolic hydroxyl functional groups.

[0021] Preferably, the polyphenol is selected from at least one of tannic acid, ellagic acid, gallic acid, anthocyanin and dopamine.

[0022] The present invention uses polyphenols with good biocompatibility as one of the wall materials, which not only achieves the adjustable release of the core material, but also the polyphenols themselves have multiple functions such as antioxidant and antibacterial, so that the electronic atomization liquid has certain antioxidant and antibacterial effects, avoiding the oxidation of components in the electronic atomization liquid or the growth of microorganisms in the electronic atomization liquid, and is healthier and safer when used.

[0023] Preferably, the magnetically responsive metal ions include Fe3+ ion.

[0024] Preferably, the magnetically responsive metal oxide nanoparticles include Fe3O4 nanoparticles.

[0026] Preferably, the polyol is selected from at least one of glycerol, propylene glycol, triethylene glycol and ethylene glycol.

[0027] Preferably, the polyols are glycerol and propylene glycol, and the mass ratio of glycerol to propylene glycol is 1:(0.1-8).

[0032] S1: homogenizing and emulsifying the emulsifier, the solvent and the core material to prepare an emulsion;

[0033] S2: Mixing the emulsion, the magnetic responsive material and the polyphenol to prepare the magnetic responsive microcapsule.

[0034] Preferably, the method for preparing the magnetic responsive microcapsules further comprises performing step S3 after step S2, and step S3 is: adjusting the pH to 7-9.

[0035] Preferably, the method for preparing the magnetic responsive microcapsules further comprises performing step S4 after step S3, wherein step S4 comprises: washing with water, and then centrifuging at a speed of 2000-10000 rpm to separate the magnetic responsive microcapsules.
