The present invention relates to an electronic cigarette for convenient injection of cigarette liquid, manufacturing method thereof, and a method for injecting cigarette liquid into the electronic cigarette. A liquid injection hole (11) is opened at a bottom of a liquid storage cup of the electronic cigarette, and the liquid injection hole (11) is sealed by a sealing element (2) which is self-closing once an injection device (1) has been pulled out from the scaling element (2). A method for manufacturing the electronic cigarette of the present invention comprises: concaving the bottom of the liquid storage cup (1) to form a cavity (12), opening the liquid injection hole (11) at a centre of a bottom wall of the cavity (12), protruding a wall of the liquid injection hole (11) towards an interior of the liquid storage cup (1) to form a protrusion (13), and snap-fitting the protrusion (13) into a circular recess (23) of the sealing element (2). A method for injecting cigarette liquid into the electronic cigarette of the present invention comprises: opening the liquid injection hole (11) at a centre of the bottom of the liquid storage cup (1), manufacturing the sealing element (2) which is used for sealing the liquid injection hole (11); inserting the sealing element (2) tightly into the liquid injection hole (11); fixing a mouthpiece cap (3) to a mouth portion of a shell (5) of the electronic cigarette; inserting the injection device (4) into an opening of the mouthpiece cap (3) and the sealing element (2) to inject cigarette liquid into the electronic cigarette; and pulling the injection device (4) out from the sealing element (2), the sealing element (2) being self-closed once the injection device (4) has been pulled out from the sealing element (2). The components of the electronic cigarette of the present invention can be assembled together first prior to the injection of cigarette liquid. Therefore, the problem of leakage and contamination of cigarette liquid during the manufacture of existing electronic cigarettes can be overcome. The electronic cigarette can be efficiently and automatically manufactured, the injection of cigarette liquid can be carried out at places where the electronic cigarettes are sold. |
