Atomizing core with air flow chamber

Abstract

An atomizing core includes a heating unit, and a liquid transfer unit made of a porous material. The liquid transfer unit includes an air guide part, and a base surrounding the air guide part. A gap between the air guide part and the base forms an air flow chamber. The liquid transfer unit is provided with an air inlet communicated with the air flow chamber, an air outlet communicated with the air flow chamber, and a liquid inlet part for contacting with the liquid. The heating unit includes a heating part disposed on an inner wall of the air flow chamber and contacting with the liquid transfer unit, and electrical connection parts for transmitting currents to the heating part. The volume, flow rate and path of the air flow are determined mainly by the structure of the liquid transfer unit, so the consistency of the atomization effect is guaranteed.
