Description

Electronic cigarette {ELECTRONIC CIGARETTE}

The present invention relates to an electronic cigarette, and more particularly to an electronic cigarette for supplying the liquid of the liquid storage unit to the vaporization unit by the pumping action.

Tobacco is a favorite item frequently used by smokers.

However, it is not generally recommended to cause various diseases such as lung cancer and circulatory diseases (such as laryngeal cancer and Burger's disease caused by vasoconstriction) caused by harmful substances such as tar included in cigarettes.

Moreover, since the situation is causing damage to people around by secondhand smoke, the smoking cessation movement is spreading widely, and the places of smoking cessation are also greatly increasing.

Nevertheless, it was very difficult to quit habitually smoking because of its addictive nature.

Recently, a lot of assistive devices and aids such as smoking cigarettes, smoking gum, smoking aid pipes, etc. to help you quit smoking have been developed and commercialized.

In particular, the smoking cessation auxiliary pipe is provided with a mouthpiece containing various substances that react well with tobacco smoke to filter nicotine and tar when smoking. It is not sufficient to provide a smoking cessation effect by causing a rejection of tobacco taste by function.

In order to improve the problems described above, a lot of research and development is in progress, and recently, an electronic cigarette (ELECTRONIC CIGARETTE) has been released.
