Clearomizer, cartridge, and electronic cigarette

A cartridge, comprising a clearomizer, a column tube for accommodating the clearomizer, a third conductive connector, and a fourth conductive connector;

• wherein:
• the clearomizer comprises a first main body and a second main body;
• wherein, the first main body comprises a first distal end away from the second main body;
• the first distal end comprises a mouthpiece;
• the second main body comprises a second distal end away from the first main body;
• the clearomizer further comprises a first conductive connector and a second conductive connector both disposed on the second distal end;
• the column tube comprises an open top, a cavity, and a bottom wall;
• the second main body is inserted through the open top into the cavity;
• the third conductive connector and the fourth conductive connector are disposed on the bottom wall and are electrically connected to the first conductive connector and the second conductive connector, respectively;
• the third conductive connector and the fourth conductive connector each are a singular conductive metal attractable by a magnet;
• and/or
• the third conductive connector comprises a third electrode and a third magnetic attraction member;
• the third magnetic attraction member is hollow and is disposed around an outer periphery of the third electrode;
• or the third electrode is hollow and is disposed around an outer periphery of the third magnetic attraction member;
• or the third magnetic attraction member and the third electrode are connected in parallel;
• the fourth conductive connector comprises a fourth electrode and a fourth magnetic attraction member;
• the fourth magnetic attraction member is hollow and is disposed around an outer periphery of the fourth electrode;
• or the fourth electrode is hollow and is disposed around an outer periphery of the fourth magnetic attraction member;
• or the fourth magnetic attraction member and the fourth electrode are connected in parallel.
