Atomizer and electronic cigarette having same

Abstract

An exemplary atomizer includes a housing and an atomizing core arranged in the housing. The housing defines a liquid chamber configured for accommodating tobacco liquid. The atomizing core is configured for atomizing the tobacco liquid to form aerosol. The atomizing core includes a hollow tubular heating body and a liquid conducting element wrapping around the heating body. The liquid conducting element is configured guiding the tobacco liquid in the liquid chamber to the heating body for atomization. The heating body defines a passage for aerosol. The heating body is made of metal. The heating body includes a sidewall defining a plurality of openings.
