Electronic cigarette

An electronic cigarette, the electronic cigarette comprising a sensor and an atomizing assembly both of which are disposed in a housing, wherein the atomizing assembly is provided with a first airflow passage, a second airflow passage is provided in the housing, and the sensor is disposed in the second airflow passage, the housing is defined with a first air inlet and a second air inlet, the first air inlet is in fluid communication with the first airflow passage, the second air inlet is in fluid communication with the second airflow passage, the first airflow passage and the second airflow passage are isolated from each other by a partition member;

• wherein the atomizing assembly comprises an atomizer head and a venting unit, the atomizer head is disposed at a bottom end of the venting unit, the venting unit comprises an inner air pipe and an outer air pipe, the inner air pipe is coaxial with and disposed inside the outer air pipe, a gap between the inner air pipe and the outer air pipe forms an air inlet passage, two ends of the air inlet passage are respectively in fluid communication with the first air inlet and the atomizer head, an air outlet passage is defined inside the inner air pipe, two ends of the air outlet passage are respectively in fluid communication with the first airflow passage and the atomizer head, whereby the external air enters from the first air inlet, flows downward along the air inlet passage toward the atomizer head, mixes with the smoke generated at the atomizer head, then flows upward along the air outlet passage toward the first airflow passage, and finally exits from the first airflow passage for being inhaled;
• wherein the electronic cigarette further comprises a liquid storage unit, the liquid storage unit comprises a liquid storage sleeve, the liquid storage sleeve is coaxial with and disposed outside the outer air pipe, a gap between the liquid storage sleeve and the outer air pipe forms a liquid storage chamber for storing cigarette liquid, the liquid storage chamber is in fluid communication with the atomizer head.
