## Background
FIELD
The present disclosure generally relates to the field of electronic cigarette, and more particularly to an E-liquid separation mechanism, electronic cigarettes having the E-liquid separation mechanism, and methods of using the electronic cigarettes having the E-liquid separation mechanism.
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 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.
When E-liquid is filled in an electronic cigarette before shipment out of a factory, the E-liquid is always in contact with an E-liquid storage medium, and exposed to air causing vaporization. The oxidation of the E-liquid may cause certain bad smell or bad taste with users. Therefore, it is desirable to separate the E-liquid from the E-liquid storage medium before users are ready to use them, and/or between each use.
Therefore, an unaddressed need exists in the art to address the aforementioned deficiencies and inadequacies.

DETAILED DESCRIPTION
The present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the disclosure are shown. This disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Like reference numerals refer to like elements throughout.
It will be understood that when an element is referred to as being “on” another element, it can be directly on the other element or intervening elements may be present therebetween. In contrast, when an element is referred to as being “directly on” another element, there are no intervening elements present. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

In yet another aspect, the present disclosure relates to a method of using an electronic cigarette 10 having an E-liquid separation mechanism as shown in FIG. 9.
At query block 902, the user determines whether an E-liquid storage tank assembly 101 is in an up position. When the electronic cigarette 10 is shipped out of factory, or it is not in use, the E-liquid storage tank assembly 101 is usually in the up position so that the E-liquid from an E-liquid storage tank 1012 is separated from the vaporizer assembly 102 and E-liquid supply path is blocked. When the E-liquid storage tank assembly 101 is in the up position, the method proceeds to block 904. Otherwise, the method skips block 904 and proceeds to block 906.
At block 904, the user pushes down the E-liquid storage tank assembly 101 against a vaporizer assembly 102 from the up position to a down position.
At query block 906, the user determines whether the E-liquid storage tank assembly 101 is in a first position. When the electronic cigarette 10 is not in use, the E-liquid storage tank assembly 101 is usually placed in the first position so that the E-liquid from the E-liquid storage tank 1012 is separated from the vaporizer assembly 102 and the E-liquid supply path is blocked. When the E-liquid storage tank assembly 101 is in the first position, the method proceeds to block 908. Otherwise, the method skips block 908 and proceeds to block 910.
At block 908, the user rotates the E-liquid storage tank assembly 101 against the vaporizer assembly 102 from the first position to a second position. When the E-liquid storage tank assembly 101 is in the second position, a first E-liquid storage tank base opening 10141 and a second E-liquid storage tank base opening 10142 defined on a vaporizer base 1024 of the vaporizer assembly 102 coincide with a first vaporizer E-liquid opening 10231 and the second vaporizer E-liquid opening 10232 defined on a heating element base 10235, respectively, allowing E-liquid filled in the E-liquid storage tank 1012 to flow into a cylindrical E-liquid storage medium 1022 to be vaporized by one or more heating elements 1023 through E-liquid paths formed between the first E-liquid storage tank base opening 10141 and the first vaporizer E-liquid opening 10231, and the second E-liquid storage tank base opening 10142 and the second vaporizer E-liquid opening 10232, respectively.
At block 910, the user turn an electrical power supply to provide electrical power to the one or more heating elements 1023 of the vaporizer assembly 102 to vaporize the E-liquid flowed to the cylindrical E-liquid storage medium 1022 when the E-liquid storage tank assembly 101 is in the second position, and sucks E-liquid vapor from the vaporizer assembly 102 through a mouthpiece 1011. Air outside of the electronic cigarette 10 enters the vaporizer assembly 102 through a first vaporizer air intake 10233 and a second vaporizer air intake 10234 to be vaporized by the vaporizer assembly 102, and the vapor formed by the vaporizer assembly 102 exits through a vapor output 1013 and the mouthpiece 1011.
In certain embodiments, when the user finish using the electronic cigarette 10, the method also includes: determining, by the user, whether the E-liquid storage tank assembly 101 is in the second position, rotating, by the user, the E-liquid storage tank assembly 101 against the vaporizer assembly 102 from the second position to the first position, when the E-liquid storage tank assembly 101 is determined to be in the second position, and pulling up, by the user, the E-liquid storage tank assembly 101 against the vaporizer assembly 102 from the down position to the up position to terminate the E-liquid flow and separate the E-liquid in the E-liquid storage tank 1012 from the cylindrical E-liquid storage medium 1022.
