Heating core and atomizer thereof

Abstract

A heating core and an atomizer thereof are provided. An air vent is arranged in a middle of the heating core to connect with an air pipe of the atomizer so that generated smoke can pass therethrough, that is, a separate aperture for smoke passing therethrough is provided to avoid a large reduction in the amount of smoke caused by micro-pores blockage. When current flows to an inner ring thereof, because the current will disperse to two half rings that form a parallel effect thereof, heating capacity of the inner ring is lower than that of a first extension section or a second extension section. An area of the first cross section of the heating core is less than an area of the second cross section of the heating core, so that a resistance of the inner ring is less than that of the first or second extension sections.
