Description

Electronic cigarette for refill

More particularly, the present invention relates to an electronic cigarette for refilling, and more particularly, to a cigarette refill for cigarettes, which is not excessively supplied to fibers of an atomizer, is always supplied in an appropriate amount, The present invention relates to an electronic cigarette for refilling, which is capable of shutting off a cigarette liquid which can be inhaled together with smoke,

Electronic cigarette devices typically include electronic cigarettes and electronic cigarette cases for storing electronic cigarettes and for charging electronic cigarettes. Conventional electronic cigarettes include a suction rod and a power rod, and the suction rod and the power rod are usually integrally coupled through a thread. When the electronic cigarette is not used, the suction rod and the power rod are usually separated from each other, It is stored in the corresponding insertion slot of the case.

The conventional electronic cigarette case includes a case body, a bracket for accommodating the power rod of the electronic cigarette and the suction rod, and a power assembly for charging the power rod, The power source assembly includes a battery, a PCB substrate, and a first connector. The first connector is a copper-made sleeve member having internal threads. A second connector is mounted on the power rod, The second connector is correspondingly inserted into the first connector to implement charging.

On the other hand, the electronic cigarette for refilling includes an atomization device for storing the tobacco liquid phase in the suction rod and atomizing the stored tobacco liquid phase into mist. The fogging device absorbs the tobacco liquid phase by winding the high temperature resistant fiber on the heating wire, and the tobacco liquid phase absorbed by the fiber as heat of the heating wire at the time of inhalation is atomized into mist. However, such a conventional electronic refill cigarette has a problem that the cigarette liquid is excessively supplied to the fibers, and the smoke and the cigarette liquid are sucked together, thereby adversely affecting health rather than directly smoking the cigarette.

Open Patent No. 2015-0119021 (published on October 23, 2015) "Method of forming a heating element, electronic cigarette and heating element"

The object of the present invention is to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a cigarette lighter in which the liquid cigarette is not excessively supplied to the fibers of the atomizer, The present invention relates to a refillable electronic cigarette which is capable of not only leaving a liquid phase but also being fumed so as to be sucked only in fog, and capable of shutting off a liquid tobacco which can be inhaled together with mist.

One aspect of the refill electronic cigarette for achieving the object of the present invention is an electronic cigarette having one end connected to a battery rod and an atomization device made up of an electric heating wire and a fiber inside a hollow portion penetrating up and down, A connecting portion having a first step portion and a second step portion sequentially formed on the outer lower side of the upper projection portion having the opening portion; A cap which is fitted on an outer side of the upper projection of the connection portion and has a lower end portion in contact with the first step portion, a hollow upward protrusion portion in the upper end portion, and a liquid supply hole communicating with the opening portion of the connection portion on both lower sides thereof; An inner barrel having a lower end fitted into and engaged with an outer side and an upper side step of the upper protrusion of the cap; An outer barrel having an outer side and a bottom side of the second step portion of the connecting portion and having a lower end fitted and in contact therewith; A liquid filling portion formed between the outer barrel and the inner barrel; And a suction port coupled to an upper end of the outer barrel and the inner barrel, the suction port having a suction hole at a central portion thereof.

In addition, the suction port is formed so as to pass through the upper and lower portions, and a silicone-made expanded portion which is fixed to the packing fixing groove portion formed on the inner side of the suction port is formed on the upper side. An insertion portion inserted into the inner barrel below the expanded portion is integrally formed And the insertion portion further includes a tapered portion which is inclined downward and inward in the outward direction.

As described above, according to the present invention, the cap blocks the outside of the opening formed in the upper protrusion of the connecting part, and only a small diameter suction hole formed on both sides of the cap communicates only a part of the opening part of the connecting part, Since the fiber is always supplied with a proper amount of tobacco liquid, the remaining amount of the tobacco liquid in the fiber upon heating of the heating cable can be completely atomized, so that only the mist can be inhaled. In this case, By blocking the liquid phase again from the packing and having a double blocking function, it is possible to reliably prevent the harmfulness of health caused by the inhalation of the liquid tobacco.

Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a sectional view showing the internal structure of a suction rod of an electronic cigarette according to the present invention. As shown in FIG. 1, the present invention includes a connecting part 2 connected to a battery rod, a cap 3 connected to the connecting part 2 An outer barrel 5 in which a lower portion is supported by the connecting portion 2 so as to be spaced apart from the inner barrel 4 and an outer barrel 4 which is supported by the outer barrel 4, (7) which is coupled to the upper ends of the outer barrel (5) and the inner barrel (4) and has a suction hole (71) at a central portion thereof, a liquid filling portion (6) formed between the inner barrel ).

2, the connecting portion 2 includes an atomizing device composed of an electric heating wire C and a fiber S on the inside of a hollow portion 20 penetrating up and down as shown in FIG. 2, The first step portion 23 and the second step portion 24 are sequentially formed on the lower outer side of the upper projecting portion 21 having the projecting portions 22. The cap 3 is fitted on the outer side of the upper projecting portion 21 of the connection portion 2 and has a lower end portion abutting on the first step portion 23 and a hollow upward projecting portion 31 on the upper end portion, A liquid supply hole 33 communicating with the opening 22 of the cap 2 is formed so that the lower end of the inner barrel 4 is fixed to the outer side of the upper projecting portion 21 of the cap 3 and the upper step portion 32 of the cap 3 And are fitted to each other. The lower end of the outer barrel 5 is fitted to the outer side and the bottom of the second step portion 24 of the connecting portion 2 so as to be in contact with each other.

The suction port 7 is formed by passing through the upper and lower portions as shown in FIG. 3 and has an expansion part 72a made of silicone which is fixed to the upper side by being fixed to the packing fixing groove part 73 formed on the inner side of the suction port 7, And an inserting portion 72b inserted into the inner barrel 4 downwardly of the bulging portion 72a is integrally formed of the same material and the inserting portion 72b is formed to be inclined downward inward And further includes a taper 72c.

In the present invention constructed as described above, the tobacco liquid phase filled in the liquid filling portion 6 is supplied between the outer barrel 5 and the inner barrel 4 through the liquid supply hole 33 of the cap 3, S, and when the smoking cigarette C is heated, the tobacco liquid absorbed in the fibers is atomized into mist. The smoky smoke is sucked through the inner tube 4 through the suction hole 71 of the suction port 7 so that the smoke is sucked between the taper 72c of the liquid-liquid packing 72 and the inner barrel 4 The inlet of the liquid-liquid packing 72 is narrowed by the action of the suction force, so that the tobacco liquid phase that follows may be blocked and only the atomized mist can be sucked. On the other hand, the tobacco liquid phase of the liquid filling portion 6 can be prevented from leaking through an O-ring between the suction port 7 and the outer barrel 5 which are helically connected to each other. (Not shown) may be formed on the outer barrel 5 so that the remaining amount of the liquid tobacco can be visually confirmed.

In this case, only the suction hole of the small diameter formed on both sides of the cap communicates only a part of the opening portion of the cap, so that the fiber of the atomizer device provided inside the connection portion is always The amount of tobacco liquid remaining in the fibers is small when the heating of the heating wire is performed, so that it can be completely atomized and can be inhaled purely. Thus, the tobacco liquid which can come along with the mist can be re- By having a double-blocking function by blocking the secondary packing, it is possible to reliably block the health hazards due to the inhalation of the liquid tobacco.
