Background

The electronic cigarette is a novel electronic product, which has similar appearance to a common cigarette and has the same taste as the cigarette. Because the electronic cigarette heats the tobacco tar through the atomizing device and produces the flue gas that can suck, compare with traditional cigarette, the electronic cigarette is not burnt, does not have the produced multiple harmful chemical substance after the burning, does not have the harm that "second-hand-cigarette" caused other people and the pollution to the environment, therefore the more healthy and the environmental protection of electronic cigarette for traditional cigarette.

Because prior art's electron cigarette adopts the mode of heating to atomize the tobacco tar, and the cartridge rapid heating up and conduct to the cigarette holder rapidly in atomization process leads to too high with user direct contact's cigarette holder temperature, not only influences user's smoking and experiences, still causes the mouth scald to the user easily. Although there are also measures for cooling the atomizer, the cooling device is disposed downstream of the flue gas flow. Because the downstream position is close to the position where the user contacts the cigarette holder, if the temperature is not reduced in time, the contact part of the cigarette holder and the user is easy to scald. And the heat sink of prior art when one end refrigeration cooling, the other end produced the heat to the condition of heat gathering appears easily, has seriously influenced the cooling effect of cigarette bullet.
