Electronic cigarette

An electronic cigarette, comprising:

• a shell assembly;
• a power generation assembly mounted inside or outside the shell assembly;
• and
• a storage battery mounted inside the shell assembly,
• wherein the power generation assembly comprises a microgenerator electrically connected with the storage battery and a power generation blade mounted on the microgenerator;
• external air drives the power generation blade to rotate;
• the rotation of the power generation blade drives the microgenerator to generate electricity;
• and the electricity generated by the microgenerator is stored in the storage battery,
• wherein the power generation assembly is mounted inside the shell assembly, and further comprises a power generation airflow passage;
• the shell assembly defines a ventilation hole communicating with one end of the power generation airflow passage;
• both the microgenerator and the power generation blade are mounted inside one end of the power generation airflow passage proximal to the ventilation hole;
• and, external air flows into the one end of the power generation airflow passage via the ventilation hole to drive the rotation of the power generation blade and then flows out from the other end of the power generation airflow passage, and
• wherein the power generation assembly further comprises a first ventilation conduit which is arranged above the power generation blade and has an opening at one end directly facing the power generation blade;
• an inner cavity of the first ventilation conduit constitutes a part of the power generation airflow passage;
• the shell assembly comprises a housing and a bottom cover mounted at an end of the housing;
• the ventilation hole is defined on the bottom cover;
• and, both the power generation assembly and the storage battery are mounted inside the housing.
