Title: Electromagnetic vaporizer and electronic cigarettes having the same

Description:
FIELD 
     The present disclosure generally relates to the field of electronic cigarettes, and more particularly to an electromagnetic vaporizer, electronic cigarettes having the electromagnetic vaporizer, and the methods of using electronic cigarettes having the electromagnetic vaporizer. 
     BACKGROUND 
     It is well known that smoking cigarette is harmful to smoker&#39;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&#39;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. 
     Conventional electronic cigarettes use a resistive heater to heat E-liquid in the electronic cigarette. This type of resistive heater has low energy efficiency, rate of temperature rise is low, is unable to reach very high temperature in a short period of time. The lifespan of this type of resistive heater is short. It is desirable to have an electronic cigarette that consumes less energy, rises the temperature in a rapid rate, reaches high temperature in a relatively short period of time, and has long lifespan. 
     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. 
     Furthermore, relative terms, such as “lower” or “bottom”, “upper” or “top,” and “front” or “back” may be used herein to describe one element&#39;s relationship to another element as illustrated in the Figures. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the Figures. For example, if the device in one of the figures is turned over, elements described as being on the “lower” side of other elements would then be oriented on “upper” sides of the other elements. The exemplary term “lower”, can therefore, encompasses both an orientation of “lower” and “upper,” depending of the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. The exemplary terms “below” or “beneath” can, therefore, encompass both an orientation of above and below. 
     Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein. 
     As used herein, “around”, “about” or “approximately” shall generally mean within 20 percent, preferably within 10 percent, and more preferably within 5 percent of a given value or range. Numerical quantities given herein are approximates, meaning that the term “around”, “about” or “approximately” can be inferred if not expressly stated. 
     Many specific details are provided in the following descriptions to make the present disclosure be fully understood, but the present disclosure may also be implemented by using other manners different from those described herein, so that the present disclosure is not limited by the specific embodiments disclosed in the following.
