Atomizer and electronic cigarette having the same
An atomizing head and a ventilation assembly are included in an atomizer for an electronic cigarette. The atomizing head includes an atomizing core and an atomizing tube. The circumference of the atomizing core defines airflow channels, so that air can flow into the atomizing core. This avoids the leakage caused by negative pressure when a user is inhaling smoke. The atomizer causes outside air to be more fully mixed with the smoke generated from liquid tobacco, and the user's experience is improved.
