FIELD OF THE INVENTION:
The present invention pertains to a device that provides sensory experience to the users. More
particularly, the present invention pertains to novel E-cigarette or vaping devices or inhalation
devices.
BACKGROUND OF THE INVENTION:
E-cigarettes or vaping devices or inhalation devices have become popular as replacement
products to conventional cigarettes and for those who are unwilling to quit tobacco smoking or
unable to quit with medical advice and pharmaceutical methods. Generally e- cigarettes have an
advantage over other nicotine supplements in that electronic cigarette may aid in smoking
cessation and are likely to be more effective than traditional pharmacotherapy, as the physical
stimuli of holding and puffing on the electronic cigarette may be better at satisfying short term
craving. E-cigarettes or vaping devices or inhalation devices are expected to be less toxic than
traditional cigarettes, and evidence suggests that they are safer than conventional cigarettes, and
possibly as safe as any other nicotine replacement product. The conventional cigarette provides
smoking experience by burning of tobacco wrapped in a paper, and the smoke consists of several
constituents such as tar, aldehydes, Poly Aromatic Hydrocarbon's (PAH's), Carbon Monoxide
(CO), Benzo-o-pyrene along with nicotine vapor. It has been known that smoke constituents
such as tar, aldehydes, PAH's, CO and several other compounds are harmful, and hence, product
development efforts were directed at providing nicotine vapor without tar, CO, aldehydes and
PAH's to the smoker.
Hence, the present invention provides a novel device and method of vaporizing the tobacco
extract and other flavored liquid with or without nicotine in a controlled way and produce
nicotine vapor without harmful components such as carbon monoxide (CO), Benzo-o-pyrene,
aldehydes, poly aromatic hydrocarbon's (PAH's) and tar by the way of controlled heating in the
E-cigarettes or vaping devices or inhalation devices.
The E-cigarettes or vaping devices or inhalation devices of the present invention comprises of
several novel and inventive elements and the elements in functional combination provide the
novel and inventive device of the present invention.
