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

The storage container 11 is for supplying a predetermined amount to the vaporization room 132 while storing the liquid, but may have a hollow inside and an open lower and upper cylinder shape, but is not limited thereto. If necessary, the storage container 11 may have a polyhedron shape. The lid 14 may be coupled to the upper portion of the storage container 11. The cover 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. The inflow hole 142 is for discharging the vaporized component generated in the vaporization room 132 to the outside. The lid 14 may be made detachable and a mouthpiece (not shown) may be coupled to the lid 14 as needed, or the lid 14 itself may function as a mouthpiece. The cover 14 is made to be detachable so as to enable the filling of the liquid inside the storage container 11.

An airtight vaporization unit 13 may be coupled to the bottom of the storage container 11. Sealing in the present specification means that the interior of the storage container 11 and the vaporization room 132 connected thereto is blocked with respect to the external space. Specifically, the solid or liquid present in the interior of the storage container 11 and the vaporization room 132 is blocked from moving from outside to inside or vice versa. However, the gas may flow between the inside and the outside of the vaporization room 132.

The sealed vaporization unit 13 has a base 131 forming a bottom surface, a coupling protrusion 133 formed along the circumference of the base 131 to be coupled with the storage container 13, and a length along the thickness surface of the outer wall. And a vaporization room 132 having an air guide hole formed in the direction and a supply gap 134 connected to the storage container, and a heating means disposed above the base.

The base 131 has a function of supporting the remaining components of the closed vaporization unit 13 while at the same time sealing the lower portion of the receiving container 11. As shown in FIG. 1B, the engaging projection 133 can be made into a form that can be fitted inside or outside the circumferential wall 111 of the receiving container 11, whereby the sealed vaporizing unit 13 has a receiving container. It can be coupled to (11). The closed vaporization unit 13 may be fixed to the receiving container 11 in various ways and the present invention is not limited to the embodiment shown.

2 (a) is a perspective view of the vaporization room and (b) is a front view respectively.

Referring to FIG. 2, the vaporization room 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 It may consist of a ventilation 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, the bottom surface 24 advantageously has a structure in which a heating means such as a heater installed in the heating means layer 23 can be fixed. The heating means layer 23 may comprise any heater known in the art, for example nichrome wire, ceramic heaters, carbon fiber heaters, planar heating elements or carbon nano heaters. It may also include an ultrasonic vibration device that can vaporize the liquid as needed. The heating means layer 23 corresponds to a layer for fixing means, such as a heater for vaporizing liquid matter 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 maintaining the liquid material supplied from the storage container 11 through the supply gap 134. The absorbent material may be, for example, a powder capable of absorbing fibers, cotton, paper or liquid, such as a nonwoven fabric, or any liquid absorbent material known in the art. When a part of the liquid material absorbed in the absorbent material is vaporized by the heating means layer 23, the liquid material may be supplied from the storage container 11 to the absorbent material again. By repeating this process, all the liquid matter stored in the storage container 11 may be absorbed and vaporized in a predetermined amount by the absorbent material.

The liquid vaporized in the vaporization layer 22 may be transferred to the residence space V or the induction pipe 121 described above through the ventilation layer 21. The ventilation layer 21 may be made of a breathable material, such as a breathable film or a porous ceramic material, which allows gas to pass but not through liquid. The size of the pores formed in the breathable material may be any size capable of permeation of the gas and not permeable to the liquid, but may preferably be 1 nanometer to 100 micrometers.

Each layer described above may be housed in a hollow housing that does not penetrate both liquid and gas with the top and bottom sides open. However, a gap corresponding to the supply gap 134 should be formed in the housing.

The air guide holes 31a and 31b may be made to penetrate the upper portion from the bottom surface of the vaporization room 132 and at least one may be formed along the circumferential surface. As shown in Fig. 2B, it is advantageous that the air guide holes 31a and 31b are formed in a portion where the supply gap 134 is not formed. The number or position of the air guide holes 31a and 31b may be appropriately selected and the present invention is not limited thereto.

Referring to (c) of FIG. 3, the outside air introduced into the air induction holes 31a and 31b may be introduced into the residence space V and discharged to the outside through the induction path 121 together with the vaporization component. Even when the retention space V is not formed in particular, or when the retention space V of a small size is formed, the bonding portion 122 and the ventilation layer 21 are adhered by, for example, an adhesive. If not, outside air can flow in. In fact, since the retention space V is formed for the inflow of external air, the retention space V does not necessarily need to be formed in consideration of the above. Outside air may be introduced into 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 the advantage of preventing the leakage of a portion of the liquid to the inside of the electronic cigarette by allowing the vaporization to occur in the closed space.
