FIELD

The present disclosure generally relates to the field of electronic cigarette, and more particularly to replaceable vaporizer assemblies and electronic cigarettes having the replaceable vaporizer assemblies.

BACKGROUND

It is well known that smoking cigarette is harmful to smoker's health. The active ingredient in a cigarette is mainly nicotine. During smoking, nicotine, along with tar aerosol droplets produced in the cigarette burning, are breathed into the alveolus and absorbed quickly by the smoker. Once nicotine is absorbed into the blood of the smoker, nicotine then produces its effect on the receptors of the smoker's central nervous system, causing the smoker relax and enjoy an inebriety similar to that produced by an exhilarant.

The electronic cigarette is sometimes referred as electronic vaporing device, personal vaporizer (PV), or electronic nicotine delivery system (ENDS). It is a battery-powered device which simulates tobacco smoking. It generally uses a heating element that vaporizes a liquid solution (e-liquid). Some solutions contain a mixture of nicotine and a variety of flavorings, while others release a flavored vapor without nicotine. Many are designed to simulate smoking experience, such as cigarette smoking or cigar smoking. Some of them are made with similar appearance, while others are made considerably different in appearance.

Replacing a vaporizer in a conventional electronic cigarette is difficult. When E-liquid gets on the vaporizer while someone is replacing the vaporizer, he/she may be contaminated with E-liquid, and it is hard to clean. Therefore, it is desirable to replace the vaporizer easily without getting E-liquid contamination.

Therefore, an unaddressed need exists in the art to address the aforementioned deficiencies and inadequacies.
