The citation and/or discussion of such references， if any， is provided merely to clarify the description of the present invention and is not an admission that any such reference is “prior art” to the invention described herein. All references listed， cited and/or discussed in this specification are incorporated herein by reference in their entireties and to the same extent as if each reference was individually incorporated by reference.

FIELD

The present invention generally relates to the field of electronic cigarette (or e-cigarette) ， and more particularly to electronic cigaretteshaving adjustable vaporizer， and methods of using the electronic cigaretteshaving adjustable vaporizer.

BACKGROUND

The background description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors， to the extent it is described in this background section， as well as aspects of the description that may not otherwise qualify as prior art at the time of filing， are neither expressly nor impliedly admitted as prior art against the present disclosure.

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 cigaretteis 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 cigarettesmoking or cigarsmoking. Some of them are made with similar appearance， while others are made considerably different in appearance.

Conventional electronic cigarettes are made with a mouth piece assembly， a vaporizer assembly， an electric connecting assembly， and an e-liquid storage assembly. The mouth piece is installed on top of the e-liquid storage assembly， and the vaporizer assembly is installed inside of the e-liquid storage assembly， and electrically connected to a DC power source through the electric connecting assembly. The mouth piece assembly is connected to the vaporizer assembly and forms an air flow passage. The e-liquid is stored in the e-liquid storage assembly. The e-liquid flows through a vaporizing chamber of the heating assembly using fiber threads. The e-liquid in the fiber threads is then heated by a heating wire of the heating assembly and therefore vaporized. The vaporized e-liquid goes up to the mouth piece such that a smoker enjoys the vaporized e-liquid. However， the vapor flow and the quantity and speed of e-liquid vaporization are not controllable or adjustable to meet the different demands of various electronic cigarette smokers.

Therefore， heretofore unaddressed needs exist in the art to address the aforementioned deficiencies and inadequacies.
