Description

FIELD

The present disclosure generally relates to the field of electronic cigarettes, and more particularly to mouth to lung convertible electronic cigarettes, and methods of using the mouth to lung convertible electronic cigarettes.

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.

Different smokers have different smoking habits. Some smokers want to have a limited amount of E-liquid vapor, and these smokers are sometime referred as mouth smokers. Others want to have large amount of E-liquid vapor, and these smokers are sometime referred as lung smokers. It is desirable to have an electronic cigarette that satisfies the needs of both types of smokers.

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.

It will be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present disclosure.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” or “includes” and/or “including” or “has” and/or “having” when used herein, specify the presence of stated features, regions, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, components, and/or groups thereof.
