Electronic cigarette and method for controlling atomization thereof

An electronic cigarette, comprising:

• an atomizer;
• a battery rod assembly detachably connected to the atomizer;
• and
• a control unit electrically connected to the atomizer and the battery rod assembly;
• wherein
• a battery is provided in the battery rod assembly for supplying power to the atomizer for atomizing cigarette liquid,
• the atomizer comprises a liquid cup assembly, a suction nozzle and an atomizer core,
• the liquid cup assembly comprises a liquid storage cartridge and an air tube inserted in the liquid storage cartridge,
• the suction nozzle made of a conductive material is provided at an end of the liquid cup assembly facing away from the battery rod assembly,
• the atomizer core detachably connected to the liquid cup assembly for atomizing cigarette liquid is provided at the other end of the liquid cup assembly,
• the atomizer core is provided with a smoke passage and an elastic conductive arm extending into the smoke passage,
• the air tube made of a conductive material is inserted in the smoke passage and elastically abuts against the elastic conductive arm,
• the elastic conductive arm is electrically connected to the control unit, the elastic conductive arm is electrically connected to the suction nozzle through the air tube,
• a conductive cartridge electrically connected to the control unit is provided on an outer periphery surface of the battery rod assembly, and
• a user touches the suction nozzle and the conductive cartridge via skin when smoking, which allows the suction nozzle to conduct with the conductive cartridge, and the control unit controls the battery to supply power to the atomizer to atomize the cigarette liquid when the control unit detects that the suction nozzle is conducted with the conductive cartridge.
