Description
- The present invention relates to electronic cigarettes, especially to an electronic cigarette with new air intake way and a mouthpiece cover thereof.
- Along with people's concern on health rising, people are aware of tobacco harmful to the body, therefore generates electronic cigarettes to replace tobacco cigarettes. Electronic cigarette is usually making e-liquid to be atomized for users smoking. Because of nicotine, tar and other harmful substances being removed during manufacturing process of e-liquid which greatly reduces harmful to users' health. Also since there is no nicotine, tar and other harmful substances in the e-liquid, after smoking electronic cigarette, people's dependent addiction on smoking will gradually become smaller, so electronic cigarette also has effects of aiding to quit smoking.
- Referring to
FIG. 1 andFIG. 2 , traditional electronic cigarette usually includes an e-liquid cup, an atomizer, an atomizationcontrol circuit board 111 and abattery 109. All the aforementioned components are disposed in aninhalation rod sleeve 110. - The atomizer is used to atomize e-liquid in the e-liquid cup to aerosol. The atomizer includes a
heating wire 106 and a liquid-guidingwick 107 operable to absorb e-liquid and support the heating wire. Theheating wire 106 winds on the liquid-guidingwick 107. Two ends of theheating wire 106 respectively connect with two electrodes of thebattery 109 by electrical wires. - The e-liquid cup includes a liquid-
storage member 102 for storing e-liquid, a liquid-guidingtube 103 for guiding e-liquid out from the liquid-storage member, an air-guidingtube 104, amouthpiece cover 101 and anatomization seat 108. Theatomization seat 108 and themouthpiece cover 101 are oppositely disposed and spaced by a certain distance. The air-guidingtube 104 is fixed between theatomization seat 108 and themouthpiece cover 101. The liquid-guidingtube 103 is sheathed at an outer of the air-guidingtube 104, meanwhile the liquid-guidingtube 103 is disposed at an internal of the liquid-storage member 102.
