An atomizer (1), an electronic cigarette, and a method for preventing e-liquid leakage when filling an e-liquid into the electronic cigarette. The atomizer (1) is used for being combined with a battery component (2) to form the electronic cigarette. The atomizer (1) comprises an atomizing sleeve (11) and, respectively inserted at either extremity of the atomizing sleeve (11), a mouthpiece (12) and an atomizing core (13) used for atomizing the e-liquid. A ventilation pipe (14) and an e-liquid storage cavity (15) used for accommodating the e-liquid (3) are provided within the atomizing sleeve (11). An e-liquid inlet (134) in communication with the e-liquid storage cavity (15) is provided on the atomizing core (13). An extensible/retractable and flexible sealing sleeve (16) sleeved at where the e-liquid inlet (134) is located is provided within the e-liquid storage cavity (15). An e-liquid filler opening of the e-liquid storage cavity (15) is provided at the extremity of the atomizing sleeve (11) in proximity to an extremity of the mouthpiece (12). A press rod (17) connected with the flexible sealing sleeve (16) is provided on the mouthpiece (12). The press rod (17) is used for pressing the flexible sealing sleeve (16) to make room for the e-liquid inlet (134) to be in communication with the e-liquid storage cavity (15). The press rod (17) is also used for being withdrawn to allow the flexible sealing sleeve (16) to reset and shield the e-liquid inlet (134) upon losing the pressing effect of the press rod (17). |
