The present invention relates to a heating structure that can be applied to an electronic cigarette and a vaporization assembly having such a heating body, and specifically, a vaporized nicotine smoke formed by integrally forming a storage container for supplying a nicotine solution and a vaporizing space to be vaporized. The present invention relates to a heating element structure and a vaporization assembly having such a heating element that can be applied to an electronic cigarette that can be prevented from leaking and at the same time allow mass production through an automated facility.

Electronic cigarettes are electronic devices that deliver a small amount of nicotine solution from a stored container to a heater and vaporize it into a smoke form that can be inhaled into a person's mouth. Such e-cigarettes were developed and commercialized in China in 2003 and developed in various forms.

A prior art related to electronic cigarettes is Patent Publication No. 2007-0022640, 'Aerosol electric cigarette'. The prior art is that the air inlet is formed and the air is introduced from the outside as the electrical switch circuit and the electrical circuit board having a high frequency generator is operated, the nicotine solution stored in the liquid supply bottle is supplied to the atomizer, the nicotine solution is vaporized by the high frequency generator Nicotine solutions that have been evaporated are disclosed for electron cigarettes that are directed to the mouthpiece through a flow passage.

Another prior art regarding electronic cigarettes is Patent Publication No. 2009-0005139, 'Aerosol Electronic Cigarettes'. The prior art includes a battery assembly, a nebulizer assembly, a cigarette bottle assembly, a cell integrated into the hollow, the battery assembly and the analyzer assembly are connected and stored inside the cell and the cigarette bottle assembly is detachable to one side of the cell.

The heater 141 may be in a strip shape or a seal shape, and the solution carrier 142 may be formed to surround the heater 141. The solution carrier 142 may be at least one fiber strand and may be disposed to wrap around the heater 141 or may be disposed side by side with the heater 141. When the solution carrier 142 becomes at least one fiber, the nicotine solution may be delivered to the heater 141 by capillary action. The nicotine solution does not necessarily have to be delivered to the heater 141 by capillary action. For example, the nicotine solution may be delivered to the heater 141 in a sprayed form.
