Description

TECHNICAL FIELD

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

[0002] The electronic atomization device is an aerosol generating device. After being inhaled by a human body, aerosols with different particle sizes are deposited in different tissue sites of the human body. For example, aerosols with large particle sizes are mainly deposited in the upper respiratory tract, such as the nose, pharynx, and larynx, and mainly affect the aftertaste of smoking. Aerosols with small particle sizes are mainly deposited in the lower respiratory tract, such as the trachea, bronchus, and alveoli, and mainly affect the texture of smoking. When the proportion of large-particle aerosols is large, the oral residue and roughness of smoke are more likely to be intensified. For example, when tobacco-flavored atomization liquid is inhaled, the oral aftertaste is not clean, and when fruit-flavored atomization liquid is inhaled, the sweet and greasy feeling is mainly caused by too many large particles.

[0041] Performance test:

[0042] The electronic atomized liquids of Examples 1-10 and Comparative Example 1 were respectively injected into a smoking device, and the generated smoke was subjected to aerosol particle size testing and sensory quality evaluation. The aerosol particle size testing was performed by using a cascade impaction test method. A cascade impactor was obtained by combining multiple impactors with different particle size cuttings. The collected aerosol particles of different particle sizes were weighed by using the cascade impactor, so as to obtain the particle size distribution of the measured aerosol. The proportions of aerosol particles with particle size ≤1 μm and >1 μm were counted, and the results are shown in Tables 2 and 3. The sensory quality evaluation was performed according to the scoring criteria shown in Table 3, and the results are shown in Table 4. Figure 1

[0048]

[0049]

[0050] According to Table 2 and Figure 1 It can be seen that, compared with Comparative Example 1, the electronic atomization liquid of the application adds aerosol adjusting atomization base liquid, the proportion of small particle size (≤1 um) particles in the generated aerosol is improved to different degrees, and the highest proportion reaches 92.0%, while the proportion of large particle size (>1 um) particles is reduced, so the electronic atomization liquid of the application can effectively reduce the proportion of large particle size particles in the aerosol and increase the proportion of small particle size particles. In addition, the sensory quality evaluation results in Table 4 show that, compared with the smoke of Comparative Example 1, the main differences of Examples 1-10 are that the aftertaste in the oral cavity is cleaner, the smoke is drier and more delicate, and the sensory quality is improved.
