1A and 1B show an exploded view and an assembled view, respectively, of an embodiment of the vaporization structure according to the present invention.

1A and 1B, the vaporization structure 10 includes a storage vessel 11 for storing liquid matter, a lid 14 coupled to the upper portion of the storage vessel 11, (12) having an induction furnace (121) which is coupled to a closed gasification unit (13) and a closed gasification unit (13) to form a retention space (V) The enclosed vaporization unit 13 includes a base 131 forming a bottom surface, a coupling protrusion 133 formed along the circumference of the base 131 and coupled with the storage vessel 11, A vaporizing chamber 132 having an air induction hole formed in the longitudinal direction along the lengthwise direction and a supply gap 134 connected to the storage vessel and a heating means layer disposed above the base, ) Is formed of a breathable material permeable to gas while it can not transmit liquid.

The vaporization structure 10 according to the present invention can be applied through a design variant suitable for any electronic cigarette. For example, the vaporization structure 10 according to the present invention may be connected to a battery assembly that is applied to a known electronic cigarette and a mouthpiece may be added as needed. The vaporization structure 10 according to the present invention is not limited by the other components of the electronic cigarette that are combined or added to form an electronic cigarette.

The storage container 11 is for storing a liquid material and supplying a predetermined amount to the vaporization chamber 132. The storage container 11 may be in the shape of an open bottom and an open cylindrical shape, but is not limited thereto. If necessary, the storage container 11 may have a polyhedral shape. The lid 14 can be coupled to the upper side of the storage container 11. The lid 14 may be made of a material such as silicone, rubber or synthetic resin, and may have an inlet hole 142 formed in the middle portion thereof. The inlet hole 142 is for discharging the vaporized component generated in the vaporization chamber 132 to the outside. The lid 14 can be made detachable and, if necessary, the lid 14 can be coupled to a mouthpiece (not shown) or the lid 14 itself can function as a mouthpiece. The cover 14 is made detachable so as to enable filling of the liquid inside the storage container 11.

The sealed vaporizing unit 13 can be coupled to the lower side of the storage container 11. [ In this specification, the sealing means that the interior of the storage container 11 and the vaporization room 132 connected thereto is blocked against the external space. Specifically, the solid or liquid existing inside the storage container 11 and the vaporization chamber 132 is prevented from moving from the outside to the inside or vice versa. However, the gas can flow between the inside and the outside of the vaporization chamber 132.

The closed vaporizing unit 13 includes a base 131 forming a bottom surface, a coupling protrusion 133 formed along the periphery of the base 131 and coupled with the storage vessel 11, A vaporization chamber 132 having a supply gap 134 connected to the storage vessel, and a heating means disposed above the base.

The base 131 has a function of sealing the lower portion of the storage container 11 and at the same time supporting the remaining components of the airtight gasification unit 13. 1B, the engaging projections 133 can be formed into a shape that can be fitted into the inside or outside of the peripheral wall 111 of the storage container 11, (Not shown). The hermetic vaporizing unit 13 can be fixed to the storage container 11 in various ways, and the present invention is not limited to the embodiments shown.

A vaporization chamber 132 having a supply gap 134 above the base 131 may be formed. The liquid material stored in the inner space 112 of the storage container 11 may be supplied to the vaporization chamber 132 through the supply gap 134.

The induction unit 12 may be installed inside the storage container 11. The induction unit 12 includes a coupling portion 122 coupled with the upper portion of the vaporization chamber 132 and a coupling portion 122 extending from the coupling portion 122 to the outside of the storage vessel 11, And an induction furnace 121 inserted into the induction furnace. The induction furnace 121 has a function of discharging the vaporized component generated in the vaporization chamber 132 to the outside.

Referring to FIG. 1B, the engaging portion 122 is coupled to the upper portion of the vaporization chamber 132 to form a retention space V. As shown in FIG. The retention space V is not necessarily formed so that the vaporized component generated in the vaporization chamber 132 is temporarily retained. However, it is advantageous that the retention space V is formed for the inflow and outflow of the outside air as described below.

Hereinafter, a vaporization chamber applied to the vaporization structure according to the present invention will be described.

Figure 2 illustrates an embodiment of a vaporization chamber in a vaporization structure according to the present invention.

Fig. 2 (A) shows a perspective view of the vaporization chamber, and Fig. 2 (B) shows a front view thereof.

2, the vaporization chamber 132 includes a bottom surface 24, a heating means layer 23 disposed above the bottom surface 24, a vaporization layer 22 formed above the heating means layer 23, And the air-permeable layer 21 formed above the vaporization layer 22.

The bottom surface 24 has a support function and can be part of the base described above. However, it is advantageous that the bottom surface 24 has a structure in which a heating means such as a heater provided in the heating means layer 23 can be fixed. The heating means layer 23 may comprise any heater known in the art, such as, for example, a nichrome wire, a ceramic heater, a carbon fiber heater, a planar heating element or a carbon nano heater. And an ultrasonic vibration device capable of vaporizing the liquid material as required. The heating means layer 23 corresponds to a layer for fixing a means such as a heater for vaporizing the liquid material supplied to the vaporization layer 22 and may include any heater or heater mounting structure known in the art .

The vaporization layer 22 may include an absorbent material capable of absorbing and retaining the liquid material supplied from the storage container 11 through the supply gap 134. The absorbent material may be, for example, a fiber, such as a nonwoven fabric, a powder capable of absorbing cotton, paper or liquid, or any liquid absorbent material known in the art. When a part of the liquid material absorbed by the absorbing material is vaporized by the heating means layer 23, the liquid material may be supplied to the absorbing material again from the storage container 11. By repeating this process, all the liquid material stored in the storage container 11 can be absorbed and vaporized by a certain amount by the absorbent material.

The liquid material vaporized in the vaporization layer 22 can be transferred to the abovementioned retention space V or the induction furnace 121 via the ventilation layer 21. [ The breathable layer 21 may be made of a breathable material such as a breathable film or a porous ceramic material that is gas permeable but liquid impermeable. The size of the pores formed in the breathable material may be any size that allows permeation of gas and does not permeate the liquid, but may preferably be from 1 nanometer to 100 micrometers.

Each of the layers described above can be received in a hollow housing in which the top and bottom surfaces do not transmit both open liquid and gas. A gap corresponding to the supply gap 134 should be formed in the housing.

It is necessary to supply air from the outside in order to suck in the vaporized liquid material.

3 (a) is a plan view of the vaporization chamber 132, (b) is a front view, and FIG. 3 (c) shows a structure coupled to the induction unit 12, respectively.

Referring to FIG. 3, air induction holes 31a and 31b may be formed along the circumferential surface of the vaporizing chamber 132 along the longitudinal direction. The air induction holes 31a and 31b may be formed to penetrate the upper portion from the bottom surface of the vaporizing chamber 132 and at least one may be formed along the circumferential surface. As shown in FIG. 2 (B), it is advantageous that the air induction holes 31a and 31b are formed in a portion where the supply gap 134 is not formed. The number or position of the air induction holes 31a and 31b may be appropriately selected, and the present invention is not limited thereto.

3, external air introduced into the air induction holes 31a and 31b may flow into the retention space V and may be discharged to the outside through the induction furnace 121 together with the vaporized components. Even if the retention space V is not formed or the retention space V of a small size is formed, the joining portion 122 and the ventilation layer 21 are bonded to each other by means such as an adhesive, If not, external air may be introduced. Since the retention space V is formed for the inflow of outside air, the retention space V does not necessarily have to be formed in consideration of the above. Outside air can be introduced into the interior of the induction unit 12 in various ways, and the present invention is not limited to the embodiments shown.

The vaporization structure according to the present invention has an advantage that a part of the liquid material is prevented from leaking to the inside of the electronic cigarette by causing vaporization to occur in the closed space. In addition, the vaporization structure according to the present invention has an advantage that the amount of vaporization of the liquid material in a part of the storage space of the liquid material is kept constant, so that the quality of the electronic cigarette remains the same. In addition, the electronic cigarette according to the present invention has an advantage that the user's suction feeling can be raised by preventing the liquid component from being contained in the vaporized component.
