An electronic cigarette (e-cigarette) capable of holding, heating, and quantitatively supplying a gelled electronic liquid (e-liquid) is provided. The e-cigarette includes an upper housing, a lower housing, a gel container, a press and reset mechanism, and an aerosol channel. The gelled e-liquid is supplied quantitatively to a heating chamber by manually pressing the press and reset mechanism. The user can adjust the time interval between pressing and releasing the press and reset mechanism according to the needs of the user for each inhalation by adjusting the length of the gelled e-liquid stick supplied to the heating chamber. Besides, a holder is provided therein with heating plates at different positions, and the holder also serves as a heating element. The design avoids the need to provide the heating element and the heating chamber separately, which reduces the volume of the smoking device.
