The present application is disclosed an atomizing component and an electronic cigarette. The atomizing component comprises a light-permeable e-liquid storage sleeve. An atomizing core is detachably connected to an end of the e-liquid storage sleeve. A fastening element for restricting radial expansion of the e-liquid storage sleeve is sleeved at where the e-liquid storage sleeve is insertedly connected to the atomizing core. An end of a ventilation pipe opposite to the atomizing core is a smoke emitting outlet in communication with a suction nozzle. An e-liquid filler hole is extended from the end of the ventilation pipe provided with the smoke emitting outlet. The smoke emitting outlet and the e-liquid filler hole are located on planes of different heights; while e-liquid is being added, the outer circumferential wall of the ventilation pipe blocks the e-liquid splashed accidentally, thus preventing the e-liquid from being splashed into the ventilation pipe.

An electronic cigarette and method for controlling the smoke amount of electronic cigarette. The electronic cigarette comprises a gas sensor (11), an atomizer (12), a voltage output unit (13) and a smoke volume control unit (14). The method for controlling the smoke amount of electronic cigarette comprises: pre-establishing the mathematical model of the relationship of smoking intensity, smoking time and the output voltage or output power; detecting current smoking intensity and smoking time of the electronic cigarette; calculating and/or finding out the corresponding voltage or power from the mathematical model, according to the detected smoking intensity and smoking time; and adjusting the voltage or power output to the atomizer (12) of the electronic cigarette according to the calculated and/or found voltage or power. Thus the smoke amount of the electronic cigarette is close or equal to the amount of the cigarette.

An apparatus comprising a heater configured to heat smokable material to volatilize at least one component of the smokable material, wherein the heater is elongate and comprises a plurality of independently controllable heating regions arranged sequentially along a longitudinal axis of the heater.

A method of controlling an electric heater in an electrically heated smoking system is provided, including providing electrical power to the heater in pulses such that during active periods power is supplied to the heater and during inactive periods power is not supplied to the heater; charging a capacitor in an RC circuit during the inactive periods and allowing the capacitor to discharge during the active periods; and monitoring a discharge voltage of the capacitor and if the discharge voltage of the capacitor drops below a threshold voltage level, then stopping further supply of electrical power to the heater.
