Description
BACKGROUND OF THE
Recently, as people have become more interested in health, it has become increasingly clear that cigarettes are at high risk for health, thus e-cigarettes are eased and e-cigarettes with fewer risks to humans are presented.
These electronic cigarettes vaporize the special tobacco liquid with a vaporizer so that the user feels as if he is inhaling the cigarette. Since the tobacco liquid does not contain toxic substances causing dependence such as nicotine and tar at the time of manufacture, smoking of the electronic cigarette gradually reduces the nicotine addiction, thereby helping to quit smoking.
At this time, as electronic cigarettes are miniaturized, various component elements are densely arranged in the electronic cigarette. In addition, the electronic cigarette is increasingly adopting a metal housing to enhance the appearance and protect the above-mentioned components.
However, since the metal housing is excellent in electrical conductivity due to the nature of the material, an electrical path can be formed between the housing and the built-in circuit depending on the specific device or depending on the location. Particularly, since the metal housing and the circuit part form a loop, when a static electricity having a high voltage instantaneously flows through a conductor such as a metal housing having a large exposed surface area, the circuit part such as an IC can be damaged, Measures are required.
On the other hand, such an electronic cigarette generally uses a charger to charge the battery. Such a charger converts an external AC power source to a DC power source and then to a low DC power source suitable for an electronic cigarette through a transformer. Here, in order to enhance the electrical insulation of the transformer, a Y-CAP composed of a capacitor is provided at both ends of the transformer.
However, when the Y-CAP does not have the normal characteristics, such as a non-genuine charger, the DC power may not be sufficiently blocked by the Y-CAP, and furthermore, a leakage current may be generated by the AC power source. Can propagate along the ground of the circuit.
Such a leakage current can be transmitted to a conductor which can be contacted with a human body, such as an external housing of an electronic cigarette. As a result, it can give a user an unpleasant feeling of crushing and, in severe cases, There is a concern.
Therefore, electronic cigarettes employing a metal housing are required to protect users from such leakage currents.
