Atomizer for electronic cigarette

Abstract

An atomizer for electronic cigarette comprises a mouth-piece, an atomization shell and a thread bushing. The atomization shell is a hollow pipe with its first end connected to the mouth-piece and second end sealed by a sealing sleeve and the thread bushing. An aerosol passage is provided inside the atomization shell. The aerosol passage has one end in communication with an orifice of the mouth-piece and another end communicating with the sealing sleeve muff-coupled to the thread bushing. The atomization shell has a first intermediary piece extending into the sealing sleeve for introducing tobacco liquid stored in the atomization shell into the sealing sleeve. An electric heater is provided between the sealing sleeve and the thread bushing. The electric heater heats up the tobacco liquid immerged in the first intermediary piece to make it atomized. The atomized tobacco liquid flows through the aerosol passage and is discharged through the mouth-piece.
