[0001] MODULAR ELECTRONIC CIGARETTES HEATING STRUCTURE [0002]

More particularly, the present invention relates to an electronic cigarette, which is installed inside a vaporization chamber and is electrically connected to a connection terminal of a battery through a body of an electronic cigarette, and heats the liquid phase transferred from the liquid carrier through an electric heating line The present invention also relates to a heating structure for electronic cigarette which generates vapor (smoke) by vaporizing a liquid phase supplied from the liquid carrier.

Generally, tobacco is a frequently used smell by smokers, and contains various harmful substances such as nicotine harmful to the human body. Therefore, various diseases such as lung cancer and circulatory diseases (such as Burger's disease caused by laryngeal cancer and vasoconstriction) And is not generally recommended. In addition, smoking cessation areas are greatly expanded because of the effects of secondhand smoke even to the people who do not smoke. However, it is very difficult for lovers to stop cigarettes that have been habitually smoking due to their addictive nature.

Recently, electronic cigarettes have been developed and marketed for smoking cessation aids, which have similar effects to actual cigarettes. E-cigarettes generally vaporize liquid essences to which flavor components are added to generate steam (smoke) as a replacement for existing cigarette smoke, thereby providing the user with a feeling similar to smoking a real cigarette.

At this time, the generated steam may contain a substance such as nicotine or tar, or may not contain any substance at all. Recently, many attempts have been made to adopt a liquid essence to which a fragrance ingredient is added so as not to give harm to the human body. Steam is generated by vaporizing the liquid essence through a heating method using an electric heating line or an ultrasonic vibration type.

A variety of techniques for heating electronic cigarettes are disclosed in Korean Patent Publication No. 10-2012-0074596 (Publication Date: 2012. 07. 06), Korean Patent Publication No. 10-2012-0113513 (Publication Date: October 15, 2012) Practical Application No. 20-2011-0010862 (Published on November 22, 2011), Korean Patent Publication No. 10-2013-0000595 (Published Date: March 2013, 2013).

When the power is supplied from the battery to the heating wire by operating the switch, the core is heated by the heating wire, so that the liquid essence introduced into the wick from the liquid tank is vaporized So that steam (smoke) is generated. The generated steam is sucked into the mouth of the user through the suction cradle of the electronic cigarette to give the user the feeling of smoking a real cigarette.

In the electronic cigarettes according to the prior art having such operating characteristics, the heating wire is fastened to a portion electrically connected to the connection terminal of the battery using a brazing welding method. Such a brazing welding method requires a certain level of skill , It was virtually impossible to replace the heating wires in the case of unskilled persons not familiar with soldering welding. In addition, even in the case of the skilled person, since the soldering iron should be provided in order to replace the heating wire, it is troublesome to replace the heating wire on the way of traveling (travel, etc.), and a soldering iron is separately purchased, Additional costs were incurred because the wire had to be replaced. In addition, when repeatedly replacing the heating wire, there is a problem that the welded portion is damaged, slag is generated, and the service life is shortened.

In order to solve these problems, Korean Patent No. 10-1524997 (filed on Feb. 27, 2015), filed on February 27, 2015 and registered on May 27, 2015, Modularized heating structure for electronic cigarette " has been proposed.

A first connection ring coupled to the first fastening protrusion so that one end thereof is coupled to the first fastening protrusion, and a second fastening protrusion coupled to the second fastening protrusion such that the other end of the electric heating wire is coupled to the second fastening protrusion 2 connecting ring.

Such a heating structure for electronic cigarette according to the related art is installed inside the atomizer chamber of the electronic cigarette by providing a heating body structure in which the heating body, the first and second connecting rings, and the heating wire are integrally modularized Separation from the atomizer chamber is easy. It is also possible to easily replace the heating wire with a simple operation of separating the heating element structure from the non-heater chamber and separating the first and second connecting rings from the heating body when the user changes the heating wire Therefore, it is easy to carry the electronic cigarette more easily than the conventional brazing welding method, and can easily and easily be mounted inside the atomizer chamber of the electronic cigarette or can be easily separated from the atomizer chamber, thereby contributing to popularization of the electronic cigarette. In addition, even for unskilled persons, it is possible to easily and easily replace the heating wire and to extend the life of the electronic cigarette without visiting the e-cigarette specialty store directly.

However, in the heating structure for electronic cigarette according to the prior art proposed by the present applicant, since the whole heating wire is made of the resistance wire, a relatively high temperature of heating occurs at the connection point between both ends of the heating wire and the first and second connection rings The heat generated by this heat may not only burn the user by overheating the entire area of the electronic cigarette through the atomizer chamber, but it may overheat the battery and cause battery explosion.

As shown in FIG. 2, the heating body 11 has a cylindrical structure having a receiving space 11a therein. For example, it can be a circular or polygonal tubular structure with four or more vertices. The first and second fastening protrusions 11-2 and 11-3 (first and second fastening protrusions 11-2 and 11-3) are fastened to both sides of the heating main body 11 in one direction Is formed.

The first and second fastening protrusions 11-2 and 11-3 can be formed to have a diameter smaller than the diameter of the heating body 11, as shown in Fig. The first and second fastening protrusions 11-2 and 11-3 are preferably formed integrally with the heating body 11 through an injection molding process in consideration of ease of manufacture and manufacturing cost, It is not. For example, when the first and second fastening protrusions 11-2 and 11-3 are worn or damaged (broken), only the first and second fastening protrusions 11-2 and 11-3 are heated by the heating body 11, The first and second fastening protrusions 11-2 and 11-3 may be fastened to the heating body 11 by a screw fastening method that is easy to attach and detach.

As shown in Figs. 1 and 3, both ends of the heating wire 14 are passed through the first and second fastening protrusions 11-2 and 11 (the first and second fastening protrusions) -3), and a communicating groove portion 11b which is recessed inwardly and formed in one direction. The bottom of the communication groove 11b is connected to the first and second connection rings 12 and 13 in a state where the heating wire 14 is positioned on the outer surfaces of the first and second fastening protrusions 11-2 and 11-3. 11-3 so as to facilitate the fastening of the first and second fastening protrusions 11-2, 11-3. Accordingly, the heating wire 14 positioned on the outer surfaces of the first and second fastening protrusions 11-2 and 11-3 passes through the communication groove portion 11b, and the first and second fastening protrusions 11-2 and 11- 3 is minimized, it is easy to fasten the first and second connecting rings 12, 13.

On the other hand, the outer surfaces of the first and second fastening protrusions 11-2 and 11-3 may be formed with recessed fitting grooves (not shown) corresponding to the communication groove portions 11b inwardly. At this time, the depth of the fitting groove is shallower than the thickness of the heating wire 14 so that a part of the heating wire 14 protrudes to the outside of the fitting groove in a state where the heating wire 14 is fitted in the fitting groove, The contact force between the first and second connecting rings 12 and 13 and the heating wire 14 in the state where the two connecting rings 12 and 13 are fastened to the first and second fastening protrusions 11-2 and 11-3 Can be increased.

As shown in FIGS. 2 and 3, the heating body 11 is preferably formed such that the side portion 11-1 is opened laterally (in the lateral direction in FIG. 1) so that a part of the heating wire 14 is exposed to the outside. Accordingly, when the liquid carrier 20 (see FIG. 5) is installed inside the heating wire 14, air can be introduced into the receiving space 11a through the opening of the side portion 11-1.

The first and second connecting rings 12 and 13 fastened to the first and second fastening protrusions 11-2 and 11-3 are electrically shorted to the heating body 11 It is formed as an insulator. For example, the insulator is formed of a ceramic material or a zirconium material, preferably a low density absorbent ceramic material. Accordingly, when heat is generated in the heating wire 14, the internal temperature of the heating wire 14 is kept constantly maintained to prevent the unsaturated boiling of the liquid phase, thereby functioning as a hot water bath. In other words, the ceramic material has a property of uniformly dissipating heat while rapidly absorbing the high temperature, and by absorbing and reducing the heat of the heating element that instantaneously generates heat by this property, it is possible to prevent the combustion of the liquid phase, Regarding the liquid phase to be supplied, it dissipates the heat uniformly and homogenizes the liquid phase. Further, depending on the degree of curing of the ceramic, the low-hardening ceramic can absorb the liquid phase and atomize the liquid phase in the ceramic, so that the bathing effect can be enhanced.
