Description

Technical Field

[0001] The present invention relates to the technical field of electronic atomization, and in particular to a smoke-free electronic cigarette atomization liquid and a preparation method thereof. Background Art

[0002] In recent years, with rising public health awareness and the advancement of global tobacco control policies, e-cigarettes have rapidly gained popularity as an alternative product that simulates the smoking experience of traditional cigarettes. They generate aerosols by atomizing a liquid containing nicotine, flavorings, and other ingredients. While this avoids the harmful substances such as tar and carbon monoxide produced by traditional cigarette combustion, several issues remain. Currently available e-cigarette liquids rely on propylene glycol (PG) and glycerol (VG) as base solvents. The high viscosity of VG results in a large amount of visible aerosol after atomization, exacerbating environmental pollution. The aerosols produced by e-cigarette liquids (i.e., secondhand smoke from e-cigarettes) contain particulate matter (including fine and ultrafine particles), a new source of air pollution that harms the environment and others. Furthermore, in recent years, government departments have issued smoking bans, strictly prohibiting smoking in indoor and other public places (i.e., smoke is prohibited). This has resulted in restrictions on both cigarettes and e-cigarettes, placing certain limitations on users. In existing technologies, some companies have tried to reduce smoke visibility by lowering the VG ratio or using alternative solvents, but they are still unable to completely eliminate smoke emissions, and their practical applications are limited.

[0003] To sum up, developing an electronic cigarette atomizer that can retain the smoking experience of traditional cigarettes while completely eliminating visible smoke has become a key technical direction to break through industry policy barriers and meet public health needs.
