The nicotine solution stored in the housing 11 must be delivered to the heating means 14 in a certain amount. The heating means 14 will be described below.

Fig. 2 shows an embodiment of the fixing structure of the heating means applicable to the vaporization structure according to the present invention.

2 (A) shows a perspective view and an enlarged view of an embodiment in which the heating means 14 is fixed to the fixing part 131 and FIG. 2 (B) shows the heating device 14 in the fixing part 131 Sectional view of a combined embodiment.

Referring to FIG. 2 (A), the fixing part 131 formed above the cover 132 may be formed as a hollow cylinder having a constant thickness. The lower portion of the cylindrical shape may be connected to the cover portion 132 and the upper portion may be an open shape. The fixing grooves 133a and 133b are formed along the circumferential surface of the opened upper portion and both ends of the heating means 14 can be fixed to the fixing grooves 133a and 133b.

The heating means for vaporizing the supplied nicotine solution will be described below.

Figure 3 illustrates various embodiments of heating means that may be applied to the vaporization structure according to the present invention.

3 (a), the heating means 14 includes a heater 143, a supply means 141 arranged along the heater 143, a heater 143, and an air permeable material (142). The heater 143 may be any heater known in the art, such as a carbon heater, a sheath heater, a nichrome wire, or a ceramic heater. The feeding means 141 can be, but is not limited to, a plurality of fiber strands, for example. The supply means 141 may be, for example, a plurality of capillaries made of a ceramic material or may be made of a yarn made in an actual shape. When the supply means 141 becomes a plurality of fiber strands or a fiber aggregate, the nicotine solution can be transferred to the heater through the capillary phenomenon. As shown in Fig. 3 (a), both ends of the supply means 141 may be exposed to the nicotine solution stored in the housing 11. The nicotine solution can be transferred from both ends of the supply means 141 through a capillary phenomenon. The nicotine solution is present in the supply means 141 arranged along the heating means 143 and the heater 143 can be heated when smoking is performed. The heating of the heater 143 causes the nicotine solution to vaporize and release to the outside of the breathable material 142. When the nicotine solution is vaporized, the nicotine solution can be supplied through the supply means 141 again.

The breathable material 142 refers to a material through which a liquid component can not pass but a gas component can pass through, and can be, for example, a breathable fabric or a breathable ceramic coating. The heating means 14 forms a closed passage across the housing 11 and a nicotine solution is present in the closed passageway. When power is supplied to the heater 141, the nicotine solution existing around the heater 141 may be vaporized and released to the outside of the air-permeable material 142, and the nicotine solution supplied to the inside of the housing 11 may be heated by the heating means (Not shown).

The breathable material 142 may be made in the form of a film or may form a feed passage in a manner that coats the feed means 141 and the heater 143. If desired, each fiber strand can be coated or wrapped by a film. The breathable material 142 may be configured to enclose a portion of the supply means 141 or the heater 142. Both ends of the supply means 141 or the heater 143 wrapped with the breathable material 142 are fixed to the fixing grooves of the fixing portion and can be sealed by the sealing material. Accordingly, the air-permeable material 141 can form a closed supply passage provided with the supply means 141 and the heater 143 therein.

As shown in (a) of FIG. 3, if the supply means 141 or the heater 143 is wrapped by the breathable material 142, wiring to an external power source such as the battery of the heater 142 may become difficult.

FIG. 3 (B) shows an embodiment in which a lead for connection to an external power source is formed in the heater 142.

Referring to (B) of FIG. 3, a non-breathable material 142b may be provided on both sides of the breathable material 142a to form a supply passage. The non-breathable material 142b is a material which can not be permeated by both liquid and gas, and is intended to specify the portion to be fixed to the fixing groove while improving the sealing of the supply passage. The non-breathable material 142b may be provided with conductive rings 144a and 144b and may have a lead function to be connected to an external power source. The conductive rings 144a and 144b may be fixed to the fixing groove and the fixing groove may be connected to a power source such as a battery. The non-breathable material 142b is not necessarily formed, and the conductive rings 144a and 144b may be formed directly on both ends of the breathable material 142a. The embodiment shown in FIG. 3 (B) is an exemplary one, and the heater 143 may be connected to an external power source in various ways.

FIG. 3 (C) shows an embodiment in which the heater 143 is formed on the outside of the breathable material 142. The air permeable material 142 provided with the feeding means 141 may penetrate the heater 143 such as a nichrome wire and both ends of the feeding means 141 may be in contact with the nicotine solution.

If the heater 143 is provided outside the air-permeable material 142, the thermal efficiency can be reduced. However, there is an advantage that the breathable material 142 and the heater 143 can be separately manufactured and combined. Further, when the heater 143 becomes a nichrome wire, it has an advantage that the heating means 14 can be easily formed.

The formation of the supply passages by the breathable materials 142, 142a shown in Figs. 3 (a), 3 (b) and 3 (c) is illustrative and various forms of supply passages may be formed.

An embodiment of the electronic cigarette to which the vaporization structure according to the present invention is applied will be described below.

FIG. 4 shows an embodiment of an electronic cigarette to which the vaporization structure according to the present invention is applied.

Referring to FIG. 4, the electronic cigarette may include a battery assembly 41, an air supply assembly 42, a housing 11, and a mouthpiece 43.

The battery assembly 41 includes a light emitting portion 411 formed on the front side thereof, a circuit board 412 provided therein, a switch 413 for operating the circuit board 412, a battery 414, The coupling portion may include an inlet hole 415 for the inflow of external air, a threaded portion 416 to be coupled to the air supply assembly 42, and an electrode connection portion 417. The air supply assembly 42 includes an engaging thread portion 426 to be engaged with the engaging portion, an induction hole 425 connected to the induction hole 415, and an induction hole 425, And an air passage 422 and a fixed block 423 for guiding the air introduced through the induction groove 421 to the vaporizing structure.

When smoking is started using the mouthpiece 43, the outside air flows into the outside of the electronic cigarette through the inlet hole 415 and the guide hole 425 and flows along the guide groove 421 to flow into the air supply assembly 42 As shown in FIG. The inflow air then operates the sensor so that the battery 414 and the switch 413 are activated. The operation of the switch 413 causes the light emitting portion 411 to emit light and simultaneously the heat generated in the heater formed in the heating means 14 by the operation of the battery 414. [ The nicotine solution supplied from the housing 11 by the heat generated in the heating means 14 is vaporized in the heating means 14 and converted into nicotine smoke. The nicotine smoke may be supplied to the mouthpiece 43 through the discharge passage 122 via the retention space 121 together with the air introduced through the air passage 422 and sucked into the mouth. In such a process, the heating means 14 forms a closed passage so that the external leakage of the nicotine solution is prevented and the nicotine smoke can be supplied to the discharge passage 122.

The illustrated embodiment is illustrative and the vaporization structure according to the present invention can be applied to various types of electronic cigarettes and can be applied, for example, to electronic cigarettes operated by a pressure switch. Also, the vaporization structure according to the present invention can be applied regardless of the manner in which the nicotine solution is stored in the housing 11.

The vaporization structure according to the present invention has the advantage that the nicotine solution is prevented from leaking to the outside. Further, the vaporization structure according to the present invention has an advantage that a certain portion of the electronic cigarette housing can be prevented from being heated by preventing the heating means from being exposed to the outside. In addition, the vaporization structure according to the present invention has an advantage that the heating efficiency for vaporization can be increased by the presence of the heating means inside.
