Novel electronic cigarette

The invention discloses a novel electronic cigarette, and aims to provide a novel electronic cigarette being stable in heating and long in service life. The novel electronic cigarette comprises a tube tobacco rod, a suction nozzle connected at one end of the tobacco rod, a smoke emitting device, a battery, a wind pressure switch and an LED lamp which are sequentially disposed in the tobacco rod from the end, close to the suction nozzle, of the tobacco rod, to the end, far away from the suction nozzle, of the tobacco rod, and a transparent or semitransparent ventilating cover which has vents and is disposed at the end of the tobacco rod. The joint of the tobacco rod and the suction nozzle is provided with a smoke mixing cavity. The suction nozzle comprises a tube body and a suction nozzle inner core fully filled in the tube. The smoke emitting device comprises a heat insulation sleeve sleeved in the tobacco rod, a PCT heater and a radiator, wherein the PCT heater and the radiator are disposed in the heat insulation sleeve and connected through thermal conduction. The radiator is arranged in the center of the heat insulation sleeve, and the PCT heater is arranged at two sides of the radiator or surrounds the periphery of the radiator. The wind pressure switch, the LED lamp, the battery and the PCT heater are electrically connected. The novel electronic cigarette is quick in heating, high in heat transformation rate and long in service life.
