Abstract

An exemplary atomizer includes an atomizing sleeve, an air pipe received in the atomizing sleeve, a mouthpiece assembly arranged at one end of the atomizing sleeve, and an atomizing assembly received in the atomizing sleeve. The atomizing sleeve and the air pipe cooperatively define a sealed liquid reserving chamber for reserving tobacco liquid. The atomizing assembly includes a liquid obstruction cover and a glass fiber core. The liquid obstruction cover includes a sidewall. The sidewall and the atomizing sleeve cooperatively defining a gap. The glass fiber core is fixed by the sidewall, and two opposite ends of the glass fiber core are both positioned in the gap. The glass fiber core is configured for absorbing the tobacco liquid in the liquid reserving chamber through the gap.
