Description

TECHNICAL FIELD [0001] The present invention relates to a vaporizing unit and an electronic cigarette including the vaporizing unit,

The present invention relates to a vaporizing unit with improved structure and an electronic cigarette comprising the same.

The electronic cigarette refers to a device for evaporating a liquid phase and sucking it, and various flavors or nicotine can be added to the liquid phase to suit the user's taste.

Such electronic cigarette does not contain tar and various harmful components which are harmful to the body, thereby giving the user satisfaction of smoking and minimizing harm caused by smoking.

Accordingly, the demand for such electronic cigarettes is continuously increasing, and product development is also being steadily carried out.

A conventional electronic cigarette includes a mouthpiece, a liquid containing portion, a vaporizing portion, and a battery. The vaporizing portion is heated by a power source applied from the battery to vaporize the liquid contained in the liquid containing portion, And has a structure sucked into a piece.

These electronic cigarettes can be broadly classified into an upper type and a lower type depending on the arrangement of the vaporizing portion. That is, the upper type may be disposed adjacent to the mouthpiece in the liquid containing portion, and the lower type may be disposed adjacent to the battery in the liquid containing portion.

Korean Patent No. 10-1364016 (entitled "Replacement Cartridge for Electronic Cigarette") also proposes a top-type electronic cigarette.

However, in the case of such an upper type electronic cigarette, there are the following problems.

First, when a user uses an electronic cigarette, a mouthpiece is placed on the upper side and a battery is placed on the lower side. Due to such a reality, if the liquid phase is not sufficient in the upper type electronic cigarette, the electronic cigarette must be periodically turned over so that the liquid phase is wetted at the core of the vaporization portion.

Secondly, when the liquid phase hardly remains, the upper liquid phase can not use the remaining amount of the liquid phase contained in the liquid phase receiving portion.

Thirdly, if the core of the vaporization part is not wetted with liquid, if the power is applied to generate heat, the core may be burned, and the gas may be sucked by the user with toxic gas, Can be accelerated.

Fourth, since the whole vaporization part needs to be replaced when the wick is replaced due to the characteristics of the upper type, it may come to the user as an economic burden.

However, in spite of this disadvantage, conventionally, in order to avoid the problem of leakage of the liquid phase to the battery through the vaporization part which is a structural shortcoming of the bottom type, and the problem of durability reduction of the battery due to such leakage, Has come.
