Description

TECHNICAL AREA

The present invention relates to the field of electronic cigarette smoke inspection and analysis technology, in particular to an electronic cigarette smoking machine with a voltage-adjustable power supply.

STATE OF THE ART

As an electronic product designed to imitate traditional cigarettes, an electronic cigarette is actually a portable vaporizer, which is usually powered by a battery and uses a built-in heating mechanism to atomize a liquid into a vapor for smoking by a user. Due to the possibility of synthesizing different flavors of the liquids and the extended ban on conventional cigarettes, electronic cigarettes are enjoying increasing popularity as a replacement for conventional cigarettes.

According to research, the smoke produced by electronic cigarettes also has a harmful effect on personal health and thus electronic cigarettes do not offer an effective means of smoking cessation. A smoking machine is required for smoke analysis of electronic cigarettes, and unlike conventional cigarettes, there are few smoking machines specifically designed for smoke analysis of electronic cigarettes available on the market. Even with smoking machines that are said to have been specially developed for smoke testing of electronic cigarettes, it is usually only possible to test those electronic cigarettes in which the nebulization of the liquid is initiated by means of a smoke air stream, while electronic cigarettes in which nebulization is initiated by pressing a push button or similar component must be started by a user, an application is not possible. Thus, the integration of turning on and off the nebulizing function in the electronic cigarette inspection process and the research on the influence of the working voltage, the working current and the operating time of the heating element in an evaporator on the smoke composition analysis become urgent problems to be solved.
