Development track of electronic cigarettes, how much do you know? | KKEMC.COM

        From the invention to the 15 years of today, the electronic cigarette has changed the products of the 7th generation in total. Today, we will talk about the development track of electronic cigarettes.

First generation of electronic cigarette
First
generation of e-cigarettes or the first e-cigarette products can be said that China’s Han Li was invented around 2000. The generation of e-cigarettes as a compact and convenient alternative to cigarettes was unique at the time, and later manufacturers basically The product serves as a prototype. The first generation of electronic cigarettes has an electronic controller that is separate from the battery. It controls the 3.7v rechargeable lithium battery to discharge current. It uses a three-stage structure of batteries, atomizers and cartridges. The battery controller limits the voltage to 4.2v through the micro board and outputs a voltage of 3.3v. After that, Han Li created a generation of products produced by the company.

Fisrt generation of electronic cigarettes
In the early days, there was not only one patent related to e-cigarettes, but they did not achieve commercial success, but the e-cigarette products invented by Han Li were successful because when Hanli invented e-cigarettes, it was exactly what consumers were thinking about. To find a healthier alternative to cigarettes, using a lithium battery controller to generate smoke is the first time people have seen it.

Second generation electronic cigarettes
With the continuous improvement of electronic cigarette equipment, the second generation of electronic cigarette products has gradually emerged. First generation of e-cigarettes is not very good to use because of battery power and voltage limitations. The smoke of a generation of e-cigarettes can only satisfy the people with less smoke addiction. The early second-generation e-cigarette model included a 14500 lithium battery case (for example: the Nicostick, an early e-cigarette prototype that was first discussed at a foreign e-cigarette forum in 2009, with a battery case on the e-cigarette). A copper tube with a two-head battery (the early prototype product had the copper).

         The first commercial-generation second-generation e-cigarette prototype was the Screwdriver made by Tog in the UK. The most typical feature of this prototype is that it has a larger RC123a lithium battery that is more stable for longer use after each charge. Trog used a resistor to reduce the battery voltage to 5v. The prototype was considered as the template for the other products at the time, but because the small-scale e-cigarette consumers at that time did not realize the existence of the product, the commercial achievement was achieved. Very limited.

  Mechanical electronic cigarette


Early products were mechanical, meaning there was no electronic control circuitry, and there was usually a spring-loaded control switch at the bottom of the tobacco rod. Some products have a voltage of 6v, they connect two lithium batteries in series, and two lithium batteries are connected in series to reach a voltage of 8.4v. This requires manual adjustment of the voltage, and improper control can result in a nebulizer voltage overload. These products are inherently very dangerous, and because the battery can be short-circuited, the atomizer instantly heats up in the semi-sealed metal pipe, eventually causing an explosion. There have been many reports of the second-generation e-cigarette explosion. There are already 15 known cases, and some people have entered the hospital, some of which are facial injuries. These problems are actually caused by the inherent defects of the preheating instability of the lithium battery and the unreasonable design of the metal tube flue gas in and out. finally
With the use of IMR lithium manganate batteries and consumers gradually turning to regulated electronic cigarettes, the end of the exploration of metal rod electronic cigarettes.

        The basic second-generation e-cigarette products are a hot topic in the early online e-cigarette community. Many people put forward the best performance configuration in the whole year of 2009. In 2010, the third generation e-cigarette 5v pressure regulating box e-cigarettes joined. Competition, at this time has been a great improvement over the early 3.7v electronic cigarette.

EGO’s medium size electronic cigarette


It is also possible to count medium-sized electronic cigarettes as second-generation electronic cigarettes. EGO electronic cigarettes have the same structure as a generation of electronic cigarettes, but they have larger sizes. Janty invented the design of EGO but forgot to apply for a patent, and then it was widely plagiarized and is now a mainstream reference for e-cigarettes. EGO’s 650mAh battery size e-cigarette is the object of many companies. EGO is also available in 900mAh, 1,000mAh and 1,300mAh versions. Like The Tornado, Riva, kGo, etc. are basically the same replica of EGO. The e-cigarette industry is actually based on constant imitation. The reason for this situation is that people did not realize the value of their own design and neglected to apply for patents, or some of them were not sufficiently regulated.

        The second generation of electronic cigarette holders combines the cartridge and the atomizer into one.

Third generation of electronic cigarettes
T
he third generation of electronic cigarettes is a true electronic adjustment device, with great progress. E-cigarettes from the beginning of a plastic box with two lithium batteries, gradually turned into a box style, in the three generations of electronic cigarette battery box, there are still two lithium batteries, usually 7.4v can reach up to 8.4v, but An electronic voltage regulator controller is installed to stabilize the battery output voltage control at 5V. The three generations of electronic cigarettes also have a 5v output voltage, using lithium batteries, and charging three advantages, reaching the ultimate goal of battery discussion on the network. The 5v battery-box e-cigarette dominates the market in 2010 and can satisfy the vast majority of consumers. It can even be said that its experience is three times that of a generation of e-cigarettes. Although the three generations of products do not need to change the different cartridges, no one cares, because the suction experience is already very good.

        Three generations of electronic cigarettes use a cigarette holder that can be repeatedly added with smoke oil.

Fourth generation of electronic cigarettes
The electronic pressure regulating box has led the trend of the fourth generation of electronic cigarettes, which was produced in the research and development laboratory of the Electronic Cigarette Forum. ECF’s four-generation e-cigarettes initially allow users to adjust the voltage from 3.3v to 6v, but still use the potentiometer buttons to provide external voltage control like the second generation, or use a screwdriver to adjust the voltage. At the beginning, the four generations of e-cigarettes did not have a display screen. Everyone had to guess how much voltage was adjusted. Later, a display like a very original electronic watch was added. Although very rough at first, the flexibility of the four generations at that time made everyone very surprised. Nowadays, the pressure-regulating device has a voltage-regulating button, which can be adjusted to a voltage of 0.1V on the display.

Electronic pressure regulator


Obviously, but the term prototype is no longer applicable at this stage, because you are already buying a product that costs almost $250 and is equipped with a format controller and LED display. Some vendors have begun to use electronic cigarettes (APV: advanced personal vapouriser) to refer to e-cigarettes, which is still the case. Now we refer to e-cigarette equipment, which refers to replaceable batteries and various components.

Fifth generation of electronic cigarettes
The fifth generation of electronic cigarettes is a voltage-increasing box type device. The voltage regulator can generate the voltage used by any atomizer, and is not limited by the battery voltage. Even a lithium battery can be used to adjust any voltage required. . If the required voltage is less than the battery voltage, the voltage regulator can suppress the voltage. If the required voltage is higher than the battery voltage, the voltage regulator can also increase the voltage. Five generations of electronic cigarettes can control the output voltage of a 3.7v lithium battery to a range of 3.3v to 6v. Of course, the amplification voltage comes at a price and requires a power amplifier to achieve. So there are 4 to 5 amplifiers in the single-cell battery regulator to generate 4.5 to 5.5. This means that the battery needs better quality. The IMR lithium manganese oxide battery has been proven to be the most cost-effective battery. There is no problem with a 18650-size IMR battery using 10 power amplifiers.

        Sixth generations of electronic cigarettes
The sixth generation of electronic cigarettes is marked with adjustable output power, which means that the wattage of the atomizer output can be adjusted. In the case of the same output power, no matter what kind of atomizer is used, the amount of smoke generated is basically There is no difference. Power control e-cigarettes have been very expensive when they first appeared. Like Evolv’s Darwin series, it is also the first six-generation commercial e-cigarette product, but the price and product size are constantly decreasing. Now the power control box is already a E-cigarette equipment that is much cheaper than the original. Now the sixth generation of e-cigarettes is a more advanced mass equipment, but the Darwin series of products will sell for a few hundred dollars at that time, but at that time the price was set to be lower, this product sold thousands of because of the addition The cost of repairs that the company invested in later became a loss-making business. Around the end of 2013, it is possible to buy a regulated rate e-cigarette for around $100.


        Power control products


One thing to note is that there is actually no such thing as true power regulation. The power value we read on the display frequency is only the converted value of voltage and current.

Seventh generation of electronic cigarettes
In the first quarter of 2015, seven generations of temperature-controlled electronic cigarettes entered the field of vision. The chip in the electronic cigarette can control the electronic cigarette device to generate a certain temperature of the flue gas. There are many advantages to this, such as avoiding drying the cotton core, and setting a maximum temperature limit to prevent thermal degradation of the smoke oil due to excessive temperature. Of course, the seventh generation of electronic cigarettes also has some shortcomings. For example, the newly used pure nickel coil of the atomizer increases with the increase of temperature, which will bring voltage fluctuation, which is not as stable as the nickel-chromium alloy coil.
