A kind of atomizer for cigarette and electronic cigarette liquid

technical field

The invention belongs to the technical field of electronic cigarettes, and in particular relates to an atomizer for cigarettes and an electronic cigarette liquid.

Background technique

In recent years, with the continuous increase of international and domestic tobacco control efforts, various low-temperature non-combustible tobacco products have been developed one after another. Among them, electronic cigarettes imitate the smoking experience of real cigarettes, and do not burn at high temperatures, reducing the release of many harmful substances, and are favored by consumers.

At present, e-cigarette manufacturers have developed e-liquids of various flavors. The main components of mainstream e-liquids on the market are a mixture of food-grade or pharmaceutical-grade glycerin, propylene glycol, and tobacco-specific flavors. Some e-liquids also contain Contains nicotine and tobacco extract ingredients, mainly to make it taste closer to cigarettes. Patent No. CN 111938197 A discloses an e-liquid for e-cigarettes, including propylene glycol and vegetable glycerin, which reduces the throat hit of the e-liquid by adjusting its ratio; Chinese patent CN109864330A discloses an e-liquid containing polyols, including At least one of pentanetriol and butanetriol, by using polyols instead of propylene glycol and glycerin in traditional e-cigarette liquids as an atomized smoke agent, solves the problem of propylene glycol and glycerin in the sweetness and dryness of smoking Problem; Another example is that an electronic atomization agent disclosed in CN104473323A includes ester compounds, water, propylene glycol and/or glycerin, and utilizes the unique taste characteristics of large molecular weight esters to screen and optimize its combination ratio and use it as The electronic atomizing agent can not only be used as an electronic atomizing agent alone, but also can be used in conjunction with existing atomizing agents. After experimental evaluation and smoking, this electronic cigarette atomizer has a good taste and can obviously overcome the sweet and greasy feeling caused by the large amount of glycerin and propylene glycol used in existing atomizers.

The above-mentioned e-cigarette agent or e-cigarette liquid mainly focuses on the aroma, flavor and taste, while ignoring the fogging ability and the release of the amount of smoke. Therefore, it is particularly important to further scientifically select a formula combination with low boiling point, low atomization temperature, large fogging amount, and no obvious sweet and greasy feeling and dry feeling in the formula of electronic cigarette atomizer.

Contents of the invention

In order to solve the above technical problems, the object of the present invention is to provide an atomizer for cigarettes and an electronic cigarette liquid. The smoke atomizer contains glycerol glucoside with a low boiling point, and adding it to the e-cigarette liquid can reduce the atomization temperature and increase the amount of smoke released.

In order to achieve the above object, the present invention provides an aerosol for tobacco, which comprises 9-11 parts by mass of glycerol glucoside, 40-60 parts of propylene glycol and 10-30 parts of glycerin.

Glycerol glucoside is a kind of alkyl glycoside, which is prepared from glycerol and glucose through glycosidation reaction. According to the difference in stereo configuration and glycosidic bond connection position, glycerol glucoside has 6 three-dimensional structures, and its structural formula is as follows:

Different Configurations of Glycerol Glucosides

Glycerol glucoside is a commonly used compound in polyol glycosides, and its main use is as a humectant, humectant, surfactant, etc. It also has moisture absorption and moisturizing functions, as well as low toxicity and low irritation, and is also widely used in the fields of medicine, cosmetics, health products and food additives. However, the inventors of the present application unexpectedly discovered that glycerol glucoside has a relatively low boiling point, and adding it to electronic cigarette liquid as an atomizer can realize rapid atomization at a relatively low heating temperature and produce a large amount of released smoke Effect, thereby satisfying the pumping experience of consumers, thereby creating the present invention.

Glycerol glucoside can be used alone as an electronic atomizer, or it can be used in conjunction with existing atomizers. However, due to the high viscosity of glycerol glucoside, when used alone, it will affect the fluidity of the e-cigarette liquid, so that the e-liquid cannot be replenished in time near the heating wire to be heated, resulting in a decrease in the fogging ability. Therefore, the atomizer also contains 40-60 parts of propylene glycol and 10-30 parts of glycerin. Propylene glycol and glycerin not only dilute glycerol glucoside, but also because of its low boiling point, propylene glycol is easy to vaporize in electronic cigarettes, and the gasified smoke has better diffusivity and filling feeling in the oral cavity and nasal cavity, and glycerin It can make the smoke thick and full, and further improve the atomization effect.

In order to obtain better blending effect and fluidity of the atomizer, as a further solution of the present invention, the viscosity of the glycerol glucoside is 56mPa·s ~ 894mPa·s.

The preparation process of glycerol glucoside in the present application is not limited, and direct glycoside method, solvent method, transglycoside method, indirect synthesis method or enzyme catalysis method can be used. As a further solution of the present invention, the glycerol glucoside is obtained by mixing glycerin, glucose and an acidic catalyst and then heat refluxing. Under acidic catalyst conditions, it is produced by the direct reaction of glycerin and glucose, with simple reaction steps, mild reaction conditions, and no chemical solvent residue.

Commonly used acidic catalysts are liquid acids such as hydrochloric acid, sulfuric acid, and phosphoric acid, which have problems such as poor selectivity, many by-products, poor product quality, and severe equipment corrosion, and a large amount of acidic wastewater cannot be recycled, which easily causes environmental pollution. As a further solution of the present invention, the acidic catalyst is an acidic activated carbon-supported catalyst, which not only has a mild reaction, but also does not corrode equipment, has little pollution, and is in a solid state and is easy to recycle; in addition, the glycerol glucose prepared by using the catalyst Glycosides have no by-products, thereby avoiding that when it is used as an atomizer, the impurities produced by the side reactions in it will not affect the quality of the suction.

Activated carbon can be loaded with various acidic compounds as an acidic catalyst. p-toluenesulfonic acid basically has the advantages of sulfuric acid, and it is also an organic acid with weak oxidation, no corrosion, and little pollution. As a further solution of the present invention, the acidic activated carbon-supported catalyst is an activated carbon-supported p-benzenemethanesulfonic acid catalyst.

As a further solution of the present invention, the molar ratio of glycerol to glucose is (10:1)~(2:1), for example, it can be 2:1, 3:1, 4:1, 5:1, 6: 1, 7:1, 8:1, 9:1, 10:1, etc. Excessive glycerin not only promotes the reaction process, makes the glucose reaction more complete, but also does not need to remove the excess glycerin raw material after the reaction, it can be directly used as a mist Therefore, the preparation of glycerol glucose of the present invention only needs to remove the solid catalyst by filtration, and does not need to remove excess glycerol, thereby avoiding strict post-processing processes such as column chromatography and distillation.

As a further solution of the present invention, the mass ratio of the acidic catalyst to the glucose is (0.02:1)˜(0.03:1).

As a further solution of the present invention, the reflux temperature of the thermal reflux is 90-150° C., and the reflux time is 4-5 hours.

In addition, the present invention also provides an electronic cigarette liquid, comprising the aerosol for tobacco as mentioned above.

As a further solution of the present invention, in parts by mass, the electronic cigarette liquid comprises 60-80 parts of the atomizer, 0.01-0.2 parts of nicotine and 1-10 parts of tobacco flavoring.

The glycerol glucoside of the present application is chemically synthesized under the condition of an acidic catalyst, the reaction conditions are mild, fast and efficient, and the post-treatment is simple. The synthesized glycerol glucoside has a low boiling point. It can not only be used alone as an electronic cigarette atomizer, but also can be used in conjunction with existing traditional atomizers. It can generate a larger amount of smoke at a lower temperature, thereby improving the quality of the electronic cigarette. Excellent smoking taste to meet the sensory needs of consumers. In addition, by rationally adjusting the ratio between it and propylene glycol and glycerin, the glycerol glucoside, propylene glycol, and glycerin are alcoholized, and degraded to generate a series of aromas that can endow the e-liquid with elegance and increase the amount of aroma, especially the sugar produced by degradation. It can increase the sweetness of the mouth during suction, thereby reducing the amount of propylene glycol and glycerin used in traditional atomizers, and reducing the sweetness and greasy feeling.
