Electronic cigarette From Wikipedia, the free encyclopedia http://www.somybox.com/Wholesale-electronic-cigarette_c987 An electronic cigarette e-cigarette or personal vaporizer is a battery-powered cigarette, vaporizer, device that provides inhaled doses of nicotine by way of a vaporized solution. alternative to smoked tobacco products, such as cigarettes, cigars, or addition  to purported nicotine delivery, this vapor also provides a flavor and sensation similar to that of inhaled tobacco smoke, while no smoke or combustion is actua involved in its operation. An electronic cigarette takes the form of some manner of elongated tube, though are designed to resemble the outward appearance of real smoking products, like cigarettes, cigars, and pipes. Another common design is the "pen-style", so nam its visual resemblance to a ballpoint pen. Most electronic cigarettes are reusa devices with replaceable and refillable parts. A number of disposable electroni cigarettes have also been developed Operation In automatic models, when a user inhales through the device, air flow is detect sensor, which activates a heating element that vaporizes a nicotine solution st  the mouthpiece. On manual models, the user must depress a button to activate t heating element to produce vapor which is then inhaled by the user. On most mod LED on the opposite end of the device is also activated during inhalation, whic as an indicator of use. Several LED colors are available from various manufactu Components While electronic cigarettes take many forms, they each generally employ the sam components: a mouthpiece, a heating element, a rechargeable battery, an electronic circuits. Mouthpiece ("cartridge") The mouthpiece is a small disposable plastic cup-like piece affixed to the end tube. Inside the mouthpiece is a smaller plastic cup which holds an absorbent m that is saturated with a flavored liquid solution that may contain nicotine. T  cup is made such that air is able to flow around it and through a hole in the e outer piece; this is necessary for the device to provide the ability for sucti the vapor into the user's mouth. The mouthpiece is referred to in the industry as a "cartridge". When the liquid in the cartridge has been depleted, it can refilled by the user or replaced with another pre-filled cartridge. Another alternative to using cartridges is the direct dripping method using By removing the absorbent material, one is able to simply remove the plastic mouth and drip several drops of e-liquid directly onto the atomizer bridge. To furthe dripping, some manufacturers have created specialty mouthpieces made of stainle steel or plastic that are intended just for dripping and do not require re time you drip. Heating element ("atomizer") The heating element serves to vaporize the liquid in the mouthpiece so that it inhaled. This component is referred to in the industry as an "atomizer". Atomiz a finite life of about one month (on average) and are one of the recurring expe associated with electronic cigarettes. Some models combine an atomizer and pre- disposable component referred to as a "cartomizer". Battery and electronics Most electronic cigarettes employ a lithium-ion rechargeable battery to power t heating element. Battery life varies depending on the battery type and size, of use, and operating environment. Many different battery charger types are availa such as wall outlet, car, and USB chargers. The battery is generally the larges component of an electronic cigarette. Some electronic cigarettes employ an electronic airflow sensor to automatically the heating element upon inhalation, while other models require the user to pre button while inhaling. Various other electronic circuits are usually employed a such as a timed cutoff switch to prevent overheating and a colored LED to signa activation of the device. Traditionally, electronic cigarettes have utilized an electronic means of a This involved the use of small tactile switches, vacuum switches and the related wir electronics necessary to run them. Users soon discovered these could be unrelia With the advent of "mods", several manufacturers have created all mechanical electronic cigarettes that eliminate the use of any wiring, solder or electroni effort to improve switch reliability. While some larger electronic cigarette models employ a user-replaceable standar battery cell, many models are too small to house a standard-size cell and inste require a proprietary component made by the electronic cigarette manufacturer. those models, the battery and electronic components are housed within a single replaceable part, which is still generally referred to in the industry simply a "battery". Nicotine and non-nicotine solution Nicotine solutions sold separately for use in refillable cartridges are referred to as "e-liquid" or "e-juice", and commonly contain some amount of flavoring, w hundreds of different flavors available. They consist of nicotine dissolved in glycol (PG) and/or vegetable glycerin (glycerol) or VG. Both PG and VG are comm food additives. Solutions are also available in differing nicotine concentrations, to let decide the amount of nicotine to be taken in. Concentrations range from Zero Nicotine, midrange doses (6–8 mg/ml and 10–14 mg/ml respectively), to high and extra-high doses (16–18 mg/ml and 20–54 mg/ml respectively). The concentration ratings are often printed at the e-liquid bottle or cartridge, although the standard "mg/ml" often gets abbreviated to just "mg". Solutions are also available that c nicotine  at all. Some flavor varieties attempt to resemble traditional cigarette types, such as tobacco and menthol, and some even attempt to mimic specific cigarette brands, as Marlboro or Camel. Fruit and other flavors are also available, such as vanil caramel, and coffee. American Association of Public Health Physicians The American Association of Public Health Physicians has come out in support of electronic cigarettes. The AAPHP recommends that the FDA reclassify the electro cigarette as a tobacco product (as opposed to a drug/device combination) and be that the effects of second-hand smoke will be significantly decreased using ele cigarettes.  Health New Zealand Ltd. study In 2008, Dr. Murray Laugesen, of Health New Zealand, published a report on the of Ruyan electronic cigarette cartridges. Ruyan funded the research, but both D Laugesen and the WHO claim that the research is independent. The presence of trace amounts of TSNAs in the cartridge solution was documented in the analysis results also indicated that the level of nicotine in the electronic cigarette was not different from the concentration of nicotine found in nicotine patches. John Britton, a lung specialist at the University of Nottingham, UK and chair of the Royal Co Physicians Tobacco Advisory Group said “if the levels are as low as in nicotine replacement therapy, I don’t think there will be much of a problem. ” The study conducted detailed quantitative analysis and concluded that carcinogens and tox are present only below harmful levels. The final conclusion of the safety repor "Based on the manufacturer’s information, the composition of the cartridge liquid is not hazardous to health, if used as intended." Manufacturers promote electronic cigarettes as a safer alternative to smoking cigarettes, claiming that most of the harmful material produced by the combusti tobacco in traditional cigarettes is not present in the atomized liquid of elec cigarettes. Despite claims that electronic cigarettes are safer, manufactures i warning labels with their products. For instance, the following advisory appear website of Green Smoke, a electronic cigarette company: “Warning: Nicotine is highly addictive. This product is not intended to diagnose, treat, cure or mitigate an or condition.” According to Cancer Research UK, "For a smoker, the health hazards of continuin smoke greatly outweigh any potential risks of using NRT". It may be worth noting, however, that while electronic cigarettes are purported to deliver nicotine t in a manner similar to that of a Nicotrol inhaler, no electronic cigarette has yet b approved as a medicinal NRT product or provided the necessary clinical testing for suc approval. Moreover, doubts have been raised as to whether electronic cigarettes actually deliver any substantial amount of nicotine at all. Though manufacturers have marketed electronic cigarettes as a way to curtail an addiction to nicotine, international health organizations have stated they may not be marketed as a cessation device. a number of regulatory agencies have issued warnings regarding the health effects of these products. The recently formed El Cigarette Association aims to eliminate unsubstantiated health claims made by electronic cigarette companies, and those companies that wish to participate in association must agree to refrain from making such claims. In a recent online survey from November 2009 among 303 smokers, it was found that e-cigarette substitution for tobacco cigarettes resulted in reduced perceived health proble compared to smoking conventional cigarettes (less cough, higher ability to do e and a better sense of taste and smell).
