电子烟介绍（Introduction of e-cigarettes）电子烟介绍(Introduction of e-cigarettes)E-cigarettes are also known as virtual cigarettes and electronic atomizer for smoking cessation and replacement cigarettes. It has the same appearance as the cigarette, the taste of the cigarette, even more than the average cigarette, and it can smoke, smell and feel like a cigarette. Electronic cigarettes contain no other harmful ingredients, such as tar or aerosol particles, and manufacturers also believe that e-cigarettes are not filled with second-hand smoke. But some studies suggest that e-cigarettes still have secondhand smoke. Because the electronic cigarettes has been a lack of systematic clinical trial data to support, some countries have decided that electronic cigarettes is illegal, in some countries as to electronic cigarettes must conform to the drug standard as a smoking cessation drugs sale. It needs to be stated that e-cigarettes have no efficacy in purification of lung, and the discussion about e-cigarette can clear lung poison is false and illegal propaganda.Chinese name: e-cigaretteElectronic cigaretteNickname: e-cigarette, electronic atomizerMain ingredients: plant extract, water, edible spicesPreservatives: noMain function: quit smoking and replace cigarettesSuitable crowd: people who have quit smoking, long-term smokers who feel bad and seek alternatives to cigarettesSide effects: the amount of nicotine in some e-cigarettes is fluctuating and may be inhaled as a lethal dose of nicotine. Some e-cigarettes are tested for toxic substances that contain nicotine.Storage: place in a cool, dry placeFunction: assist in quitting smoking and replacing cigarettesdirectoryA brief historyThe structureThe related contentSelection methodMethod of userestrictionsanA brief historyThe structureThe related contentSelection methodMethod of userestrictionsanEdit this sectionA brief historyGeneration electronic cigaretteThe original electronic cigarette is at the request of abroad, because there are a lot of foreign laws and regulations prohibit smoking in public places, and people generally high standard of living abroad, the wealthy, more strict in quality of life. So, originally designed for export of foreign trade. There were some brands at home, but they were very expensive. Almost no domestic sales, all exports. So many people don't know. But with the advent of the financial crisis, many export products have been sold out and prices have come down slowly.The design of a generation of e-cigarettes is completely modeled on the shape of ordinary real smoke, the smoke is yellow and the body is white. This generation of e-cigarettes has been popular for a few years because it is similar to real smoke andis accepted by customers in the first place. However, as people more and more on the use of the first generation of electronic cigarettes, especially foreign customers, in use process of slowly finds many of the shortcomings of the first generation of electronic cigarettes, mainly displays in the atomizer. The first generation of vaporized vaporizer is easy to burn, and when you change the smoke cartridge, it can easily hurt the tip of the atomizer. The cumulative effect of the cumulative effect will be completely worn down, resulting in no smoke from the atomizer.Secondary electronic smokeSecond generation electronic cigarettes than generation electronic cigarette is a bit long, is 9.25 mm in diameter, and the main characteristic is improved after the second generation of electronic cigarettes atomizer, atomizer outside with a protective cap, smoke flare is inserted into the atomizer inside,And a generation of e-cigarettes is an atomizer inserted into a smoke bomb, two exactly the opposite. The characteristics of the second generation of e-cigarettes are the combination of the smoke bomb and the atomizer, which is the most striking feature. The user needs to abandon the vaporizer every time he changes the smoke cartridge. Such a design can solve the problem of immaturity of the atomizer technology.Edit this sectionThe structureAlthough electronic cigarettes have style or brand, their basic structure is generally made up of three parts: battery rod, atomizer and smoke bomb.Schematic diagram of electronic cigarette structureThere are also two components: battery rods and vaporized smoke bombs, known as second-generation e-cigarettes.atomizerGenerally speaking, the smoke cartridge is the suction part, and some factories should glue the atomizer and smoke cartridge together to make a disposable atomizer. thisElectronic smoke structure diagramSample do advantage is that can greatly enhance the flavors of electronic cigarettes and smoke quantity, at the same time, the quality is more stable, because electronic cigarettes knows, atomizer is one of the most easily broken, traditional electronic cigarette is a separate atomizer, it broke a few days. This is also the fundamental reason why the e-cigarettes were questioned before. And if you keep using a single atomizer for a long time, the taste is very poor and the amount of smoke is very small. This directly affects the effect of quitting smoking. And professional liquid injection by the factory, to avoid his note to smoke too much or too less liquid back into his mouth or flow into the battery part corrosion problem of the circuit, the remaining oil smoke also more than generalsmoke bombs, sealed performance is good, so the use of his time than other smoke bombs. In this way he was more effective. The technology is currently owned by very few brands. The construction of the atomizer is a heating element, which makes the smoke and oil evaporate on the side of the battery, causing the smoke to evaporate, thus causing theinhaling to achieve the effect of "blowing smoke".rodThe inner structure of the smoke rod USES the same basic components: a lamp PCBA board, rechargeable battery, various electronic circuits.Most e-cigarettes use lithium-ion and secondary battery power components. Battery life depends on the type and size of the battery, the number of times and the operating environment. And many differenttypes of battery chargers are available, such as sockets for direct charging, car charging, and USB charger. Batteries are the biggest components of e-cigarettes.Some electronic cigarettes use an electronic airflow sensor to start the heating element, and an inhalation will make the battery circuit work. Manual sensing requires users to press a button and smoke. Pneumatic use is convenient, manual circuit is more stable than pneumatic, relatively speaking. It's better to smoke than air. Traditionally, electronic cigarettes have been activated by electronic means. This involves the use of pure hand mechanical switches andrelated circuits, heating components. Users can quickly find it's not very reliable, along with the development of the hardware and software, several automatic machinery manufacturing electronic cigarette manufacturers started to r&d, put an end to use manual wiring, welding or electronic, in order to achieve security and reliability. This is a trend, but once it's out, China can't make up its own market for making e-cigarettes in China at artificially low cost.Edit this sectionThe related contentQuit smoking principleThe most common use of nicotine replacement therapy in the world is the gradual reduction in the nicotine intake of smokers. Generally from high to low, gradual decrease. But even if the maximum concentration ofnicotine is only a third of that of a regular cigarette, it can avoid dependence on e-cigarettes.According to incomplete statistics, the electronic cigarette is nicotine replacement therapy now quit rate of the highest in all sortsof products, in addition to his used nicotine replacement therapy, hehas a big advantage, smoking is not to change my habitual action, as the saying goes, he will also be able to meet the mouth addiction to smoking. This is very important, because a large part of smokers, just can't get rid of this habit, just can't stop smoking.The working principle ofElectronic cigarettes through high-tech silicon control ofsmoke and air flow sensors output and working status of nicotine by atomization, the atomized particles into a solution containing the nicotine and essence, absorbed by the lungs, simulation of smoke at the same time. Without the tar and other harmful components of cigarettes, there will be no second-hand smoke or smoke in the enclosed space; Traditional cigarettes are lit by tobacco or tobacco, and harm thehealth of both smokers and non-smokers.Inhale, formed in sensor high-speed airflow, air flow sensors'people breathe in mouth, triggering air sensing switch, make the airflow sensor switch, products began to enter the working state. Thecentral processing unit controls the execution unit through calculation and measurement. The atomizer is controlled by the central control unit and is atomized according to the degree of oral suction. Atomizer iscomposed of high frequency oscillation circuit and the heating wire, in the atomizer, high purity electronic cigarettes liquid after superfine atomizing pump pressurized into the spray chamber, the high frequency of ultrasonic vibration on the critical atomized into droplets are about0.5 1.5 um, combined with inhalation of air dispersion into the form of aerosol, and simulation of the flue gas steam fog, look like smoke, is actually the fog. The critical atomization condition is to reduce the surface tension of the liquid to the most atomizing degree by heating, and simulate the temperature of ordinary flue gas (50-60 degree Celsius). At the same time, the green indicator light on the front of the e-cigarette lights up, simulating the cigarette flame, indicating that the e-cigarette is in the working state. When the inhalation is stopped, the air flow in the sensor disappears, the flow sensorswitches off, the circuit board IC processor stops working, the atomizer stops working, and the green indicator of the electronic cigarette end is extinguished.Scope of application1. Use the crowdChronic smoking and poor feeling.Long-term work in no-smoking places and smoking habit.There is a willing to quit.2. Applicable placesIt can be used in various smoking areas such as trains, theatres, hospitals and libraries.It can be used to prevent fire and fire units, such as gas stations and forest farms.3. Minors under 18 years of age are prohibited from using electronic cigarettes.Edit this sectionSelection method1. Quantity of smokeThe whole electronic smoke structure design, air inlet, air passage. Good e-cigarette design can guarantee a large amount of smoke, and then guarantee the stability of smoke.2. AtomizerThe function of the atomizer is the atomization, which is the core component of e-cigarette.A good electronic cigarettes, there must be a good atomizer, outstanding atomizer has the fever silk coarse, outside has the characteristic of steel ring protection, average width is about 5 mm in atomizer can guarantee good out of the smoke.Third, the batteryThe battery is connected to the atomizer, and liquid atomization requires a lot of energy, so the length of the battery life is the standard to measure whether an electronic cigarette is good. The link location of battery and atomizer with material is also key, every time when charging the place to turn, if the material is bad will soon appear wear Resulting in poor contact electronic smoke to stop working.Batteries that fuse with gold-plated technology tend to last longer than normal.Four, appearanceGood product, its appearance is relaxed, the design is rigorous, the work is exquisite, can give a person a kind of joyful feeling, help successful quit smoking.Five, the tasteThe current flavor is mostly marlboro, originally for the smoke. Taste is the defect of e-cigarette, but now it is more and more important in these years. Taste is also closer to real smoke, such as Chinese and licorice flavors are closer to real smoke. And peppermint and roasted tobacco and fruit flavors are preferred.Vi. Qualification certificationThere are many fake and inferior products on the market today, and the price is between tens and 100 yuan. These products have greatquality problems and health problems. Therefore, when purchasing e-cigarette products, it is necessary to see the relevant qualification and certification, and do not purchase fake and inferior products because of the low price.Edit this sectionMethod of useThe assembly wayElectronic smoke assembly anatomyPull out the smoke cartridge connected with the atomizer, replace it with a new smoke cartridge, and then connect it to the atomizer and smoke cartridge. Then you can enjoy the e-cigarette.Note: after the smoke of e-cigarette is opened, it is best to use it within three days.When the smoke drop is found, the smoke cartridge is used up, please change into a new smoke bomb.Use skills1. Be careful not to suck too hard when using, too hard to smoke. The smoke is sucked directly into your mouth because it is too hard to absorb, and it is not atomized by the atomizer. So it's more smoke and smoke.2. When smoking, please pay attention to take a long time to take a long breath, because the smoke in the smoke can be completely atomized by the inhaler for a long time, resulting in more smoke.3. Pay attention to the use of perspective, to keep up a cigarette holder, smoke bar downward-sloping, if smoking cigarette holder when rod up down, smoke liquid by gravity will naturally flowing downwards into your mouth.4. When the smoke comes into your mouth, take it down and take it apart, and wipe off the excess water from the cigarette's mouth and the atomizer before you use it.5. To keep the battery in sufficient power, the lack of electricity can also cause the smoke to be absorbed into the mouth without being fully atomized.Matters needing attention1. After the first or no smoke cartridge is placed for a period of time, you must first load the new smoke bomb and wait for a few minutes for the smoke to infiltrate. In the case of smokeless liquid, the use of electronic cigarette can easily damage the atomizer.2. A normal cigarette can absorb about 15 mouths.It is recommended that the user smoke the e-cigarette 14-16 for half an hour and then inhale.3. Lithium battery charging time 1.5-2 hours.The picture before the e-cigarette4. Direct inhalation of smoke from smoke cartridge is prohibited. Excessive amount of smoke can be directly exposed to the oral cavity, which can stimulate the mucous membrane of the mouth.Please put the e-cigarettes and smoke cartridge in the place where the children are not easy to contact.6. The decrease in the amount of electronic smoke and the lack of basic smoke indicate that the nicotine solution has been exhausted and new smoke cartridge should be replaced.Edit this sectionrestrictionsBecause electronic cigarette technology is relatively new, as wellas with the tobacco legal and some links of the medicine policy, so at present in many countries, legislation and public health survey about electronic cigarette is not settled yet.It is illegal to sell electronic cigarettes containing nicotine in Australia.In Austria, electronic cigarettes are believed to be medical devices, as well as medical products with nicotine tubes. Therefore, before legitimate sales, electronic cigarettes must have the CE (European commission) logo and the nicotine cartridge is registered as a medical product.In Brazil, electronic cigarette sales, imports or any form of advertising are prohibited. The Brazilian health watchdog (Anvisa) found that the current health and safety assessment of electronic cigarettes was still unsatisfactory, so that electronic cigarettes could not be commercially approved.In the Czech republic, electronic cigarette use and advertising are currently unrestricted.Electronic cigarettes are legal in Denmark, but the nicotine tube is currently under a temporary ban because of a review by Danish health authorities.In Canada, the use of electronic cigarettes is under reviewbecause of a smoking ban in public places. Canada has not yet approved market licenses for any electronic cigarette products.It is illegal to sell or buy a nicotine cartridge through theInternet in Finland, but it is not illegal to buy the nicotine cartridge used for personal use from overseas sources.It is illegal to own or sell electronic cigarettes in Hong Kong.In the Netherlands, electronic cigarettes are permitted, but electronic cigarette advertising is banned before the European Union is established.In New Zealand, the ministry of health says the nicotine canister is required to comply with the medical bill unless it is marketed as a registered drug.In panama, distribution and sales of electronic cigarettes have been banned since September 2009.In South Africa, the use of electronic cigarettes is currently unrestricted.In tajikistan, the use of electronic cigarettes is currently unrestricted.In Britain, the use of electronic cigarettes is currently unrestricted.In the United States, the food and drug administrationconsiders electronic cigarettes to be a nicotine release device that needs FDA approval. The agency is currently investigating electronic smoking devices and has prevented some electronic cigarette products from importing to the United States.Legal disputes, Virginia attorney general health in sinai, Leon (Ken Cuccinelli), because they make electronic cigarette is not to violate the Virginia indoor public places the decision of the smoking ban, but has been support and criticism from health groups different camps.The ruling means that virginians are free to use electroniccigarettes in restaurants and other places where smoking is banned.Science and health committee in the United States a message on the website of references, the Washington post reported in sinai, judgement, electronic cigarette devices from the hot water vapor does notconstitute a "usually people understand" smoke. Report quoted a spokesman of the American cancer society, the ruling "for us toestablish a smoke-free workplace and promote a healthy environment and are trying to do everything" in Virginia is backwards.But Elizabeth whelan, founder of the American council on science and health, has a different view of the situation. "The American cancer society is basically saying, 'stick with the real thing -- cigarettes,'" she said. She praised him for making such a ruling. She added: "the person who has the scientific knowledge is in contact with him and explains the actual situation to him."Disadvantages 1. E-cigarettes are not real tobacco because theydon't burn. The taste can never be the same as cigarettes.2. The e-cigarette industry is currently in a chaotic market, especially the taobao market, which is full of fake products. Even someof the best selling products, the corresponding qualifications of the manufacturers are not up to standard.3. The lack of effective supervision of e-cigarettes has led to an uncertain future.4. There is also obvious exaggeration of electronic cigarettes. For example, many people advertise that e-cigarettes have the effect of clearing lung poison. This is all illegal propaganda, electronic cigarette is not even medicine, not to be clear lung poison at all. And science has shown that e-cigarettes don't have any function of clearing the lungs. E-cigarettes now only have the effect of replacing cigarettes and helping to stop smoking.。
