Vaporizing Chip for Electronic Cigarette

The present invention relates to a vaporization chip for e-cigarettes, and more specifically, a vaporization chip for e-cigarettes, which can prevent leakage of the solution while at the same time supplying the solution to the heating element, and at the same time improve the quality of the vaporized components. It is about.

An electronic cigarette refers to a device that enables the inhalation by vaporizing a nicotine solution or a smoking solution for cigarette smoke by heat generated by electricity. Generally, the electronic cigarette may comprise a battery assembly, a supply assembly, a vaporization assembly, and a suction assembly. The battery assembly includes, for example, a rechargeable battery and can supply the power required for vaporization of the solution in the vaporization assembly. The supply assembly has the function of storing the nicotine solution, the smoking cessation aid solution or the inhalable solution and supplying it to the vaporization assembly in a certain amount during the inhalation process. The vaporization assembly has the function of vaporizing the solution with electric power supplied from the battery assembly to make the liquid into a gaseous state. And the suction assembly has the function of directing the vaporized solution from the vaporization assembly into the mouth to be inhaled.

A prior art related to electronic cigarettes is Utility Model Publication No. 2011-0010862, 'Electronic cigarette atomizer cartridge'. In the prior art, a cigarette main body portion having a battery incorporated therein is connected to the lower end, and a suction pipe portion 20 connected to the upper end of the cigarette main body portion is coupled to the upper end of the cigarette main body portion. The essence casing includes a liquid essence, A lower end cap fixedly installed at a lower end of the casing and having a cigarette main body fastening portion for detachably coupling the essence casing and the cigarette main body portion, An air inflow pipe and an air inlet pipe coupling part connected to the air inflow pipe in a downward direction are provided in an upper part of the tubular member coupled to the upper end of the air inflow pipe, An intake pipe body having two seating grooves opposed to the upper end of the peripheral wall, And a water jacket which is installed on the first air passage and has at least one end extending into the essence casing, an electric heating coil wound around the core located on the first air passage so as to be heated, A packing portion having a central portion through which the essence casing is inserted through an upper end thereof and a second air passage on the extension line of the first air passage, and a battery portion for supplying battery power to the electric heating coil And a power supply means for supplying power to the electronic cigarette.

Another prior art related to electronic cigarettes is Patent Registration No. 1081481, "Electronic cigarette atomizer cartridge." The prior art includes a liquid tank in which an essence receiving space for receiving an essence is formed and a lower end is opened and a smoke discharging hole is formed, a smoke disposed in an essence receiving space of the liquid tank and communicating with the smoke discharging hole A body which is connected to a lower end of the fluid tube and the liquid tank and has an upper opening to communicate with the flow hole and is formed with an essence inlet hole communicating with the essence receiving space and a wick provided on the inner side of the body, And an atomizer having a heating element for heating the essence, and a non-atomizer integrated cartridge for an electronic cigarette.

In the prior art, nickel-chromium wire is used as the heating element for vaporizing the nicotine solution, and the supply of the solution to the heating element is made through the fiber. Specifically, a plurality of strands of fibers penetrate into the coil-shaped nickel-chromium wire and both ends of the fibers are connected to a nicotine storage container. The nicotine solution can be delivered to the heating element through the capillary action of the fibers to vaporize. For intake of vaporized components, air must be introduced from the outside and the air passage is connected to the heating element for this purpose. In such a structure the heating element is exposed to the outside and the nicotine solution delivered to the heating element through the fibers is likewise exposed to the outside. This may cause the exposed nicotine solution to flow along an air passage, if not vaporized. On the other hand, when vaporization proceeds while the nicotine solution supplied to the heating element through the fiber is supplied in advance, a part of the nicotine solution may be sucked without being vaporized. This causes a problem that the quality of the e-cigarette is lowered and the smoking satisfaction by the e-cigarette may be lowered.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems of the prior art and has the following objectives.
